A poem depicting the life of the doctors who are the true fighters of our nation whose sacrifice and determination often goes unnoticed.

It takes a full life to realise what is True,

To earn the title Doctor is a pride for all but a dream of only a Few. Take it or leave it, it’s up to You.

Take it or leave it, it’s up to You.

It’s a lifelong journey which has to be fulfilled by You.

They acquire a lot of knowledge throughout their medical Career,

But when a patient with an unknown disease arrives it’s their biggest Barrier.

They work like soldiers at the borders to save lives at the risk of their own Demise,

Seeing the patient fully cured is their biggest Prize.

They relate every aspect of their life with their medical life,

Whenever they see a Crescent moonlight Night,

They are reminded of P falciparum gametocyte.

They possess virtues which can’t be measured by a Test.

They have special qualities which make them stand apart from the Rest.

They have the patience to calm a disturbed mind.

Being objective and also very Kind.

Applaud to the doctors who sincerely do Care.

They are like those precious stones who are found very Rare.

Let’s stand up and clap for our heroes Today,

Salute and wish them a very 

Happy Doctor’s Day

Bioelectronic Medicine

By Pratiksha Baliga

Published 6:39 PM EST, Sat July 17, 2021


Bioelectronic Medicine consists of implantable devices that will use electricity to regulate biological processes, treat diseases, and restore lost functionality. These devices would work in a manner in which they will induce, block, and sense electrical activity by taking into account the Peripheral Nervous System at the centre to progress with advances mainly concerned with chronic diseases and their control.  It will be attached to individual peripheral nerves, thereby deciphering and modulating neural signaling patterns, achieving a therapeutic effect targeting the signal function of a specific organ. These miniaturized device components will create flexible and biocompatible materials. The biggest problem with drugs is that, although they cure diseased cells, they also result in adverse reactions. Bioelectronic Medicine, as compared to drugs, will be designed with more efficiency and will comprise of expandable components for computation and power, thus reducing the side-effects and costs. It will focus on precision to reach specific targeted locations.

Ongoing Research

The research is ongoing to discover a particular methodology of harnessing the body’s peripheral wiring, which might help in the treatment of acute and chronic diseases. Dysfunctional neural circuits give rise to dysfunctional organs. The aim of bioelectronic medicine is to counteract this condition by restoring electronic impulses with adjustments of neuron firings, thereby changing the neurotransmitter concentrations traveling through those circuits.  An alternative way is emerging including neuromodulation, biostimulation, or electroceuticals to deteriorate the expense of costly chemical and biological drugs.

The human body is electric. Peripheral nerves connect all organs to the central nervous system These nerves are packaged in bundles and carry about 100,000 nerve fibers. A peripheral nerve is also the longest nerve in the body, linking the brain to the organs and controlling breathing and heart rate. It goes everywhere to gain access to a bunch of different targets. Some of the researchers believe that this is the greatest promise for bioelectronic medicine, which, by manipulating the vagus nerve, can control inflammation and the immune response and drive most chronic disease. Also, acetylcholine, the principal neurotransmitter that stems from the vagus nerve, inhibits the production of cytokines such as the tumor necrosis factor, an inflammatory molecule involved in rheumatoid arthritis.

These implants are very small in size. Researchers and engineers are into a mindset of not blindly zapping a large bundle of nerves. Instead, they are collaborating on the basic physiology and high-tech tools needed to zero in on the specific subset of fibers known to innervate the organ of interest. Further changes are thought to personalize this device in such a manner as changing the pulse, width, amplitude, or frequency of stimulation. Unlike as with many pharmacologic agents, a plan is executed to be selective with therapeutic effects along with its reduced side effects as well.

Such a device would not only develop connections with the nerves, but also with the rest of the body to decipher and develop the best response in real-time by stimulating or blocking nerve signals. For example, diabetes might involve the pancreas to make more insulin when it’s needed. In the gastrointestinal system, an electrode might sense the motility rate of the gut and then determine the optimal frequency of pulses to speed it up or slow it down. The ultimate goal is to restore a healthy pattern of electrical pulses.

Future Aspects

In the upcoming future, the vision of revolutionizing the system of medicines will come to fruition. Bioelectronic medicines hold the promise in achieving the therapeutic intervention by modulating the signalling patterns of the nerves’ impulses. These medicines include devices which are implanted anywhere in the viscera and record the neural activity. However, the upcoming research is thought to focus on three principal areas. Firstly, making of an instinctive nerve atlas is pivotal as this focuses on mapping the innervation of visceral organs such as the lungs, heart, liver, pancreas, kidney, bladder, gastrointestinal tract, lymphoid organs, and reproductive organs. The objective is achieving resolution at the level of nerve fibers and action potentials. Secondly, neural interfacing technology helps in mapping neural signals, which includes ultrasonic and tomography techniques for recording and modulation. Thirdly, when the particular signaling pattern is characterized, the focus drifts towards confirmation of rule, which implies characterizing which neural circuit exerts impact over which disease in the representative animal model. After that, an experimental phase is sought after, which includes developing the correlation of neural signals and biomarkers patterns and also investigating the effect of blocking and stimulating neural activity during established disease. Thus, altogether this revolution in the medical fraternity might bring a change in the society introducing a new class of precision medicine to patients.

Artificial Blood-A Mystery Soon to be a Reality

By Pratiksha Baliga

Published 3:03 PM EST, Tues June 1, 2021


Blood is a transport liquid pumped by the heart to all parts of the body and vice versa to repeat the process. It is also a tissue with a collection of similar specialized cells that serve particular functions. It is composed of red blood cells for transportation of oxygen and carrying back of carbon dioxide to exhale, white blood cells to fight infections, platelets to heal by clotting of blood in injuries, and plasma for circulation of platelets and blood cells in the body.

Artificial blood is a blood substitute used to mimic and fulfill some vital functions of the biological blood like the transport of oxygen and carbon dioxide. It is useful during life-sustaining conditions with serious blood loss. They cannot carry out secondary functions like fighting infections. Nowadays with the growing need for blood and reduced availability of donors, the creation of artificial blood is a need for millions. 


Human blood has a composition of products that need to be added to make artificial blood. First and most importantly it should ensure compatibility thus in this case the types of blood should not vary and be similar for all. It should also fulfill the purpose of the patient’s safety, to be able to process and remove the disease-causing agents like microorganisms, bacteria, and viruses, being pathogen-free. Secondly, the important aspect is regarding the transportation of oxygen and carbon dioxide. This feature is considered to be fulfilled by recent research. Third, it must be shelf-stable. Human blood can only be stored for a relatively short period. According to the Red Cross, storage of blood cells is done in the refrigerator at 6°C for 42 days, while platelets can be stored at room temperature in agitators only for 5days. So unlike donated blood, artificial blood should be able to be stored for at least a year or more. 


Perfluorocarbons are a group of human-made chemicals composed of carbon and fluorine. They are thought to be used to design artificial blood and dissolve about 50 times more oxygen than blood plasma. They are inexpensive and do not require any biological materials. In making it useful for artificial blood ongoing research is in talking terms in which certain hurdles have to be overcome. Firstly, correction in its solubility in water has to be brought about, which can be achieved by its combination with emulsifiers that can suspend its tiny particles in the blood. Secondly, the quantity of Perfluorocarbons has to be large as they carry much less oxygen than hemoglobin-based products. Thus improved emulsions will be developed in the subsequent time, the process of which has begun. 

Haemoglobin Based Products

Hemoglobin carries oxygen from the lungs to the other body tissues. Artificial blood made according to this principle has an advantage due to its natural function. Unlike in Perfluorocarbons, the oxygen covalently bonds to hemoglobin. It has another advantage of eliminating blood typing as they aren’t contained in a membrane and are different from the whole blood. Along with having the pros, hemoglobin-based also has some cons. Firstly, stability is an issue.

Secondly, its raw material cannot be used as it would lead to breaking down into small toxic products inside the body. Therefore artificial blood hemoglobin-based should be made by resolving these issues. The stability of it can be brought about by chemically cross-linking or using recombinant DNA technology to produce modified proteins.

The cross-linking has specific chemical cross-links which prevent dissociation to dimers or monomers. Therefore these hemoglobins attain the properties of solubility and stability. Thus it is expected that these modified ones should have a greater ability to carry oxygen than our red blood cells. The research is going on and its availability is expected to be within some years.

Process in Making

Perfluorocarbons involve polymerization reactions for the making of artificial blood. Hemoglobin-based products are mostly preferred which can be used by isolation or synthetic production with the use of amino acids. It also uses specific types of bacteria and materials needed to incubate it like warm water, glucose alcohol, urea, acetic acid, and liquid ammonia. Later the process involves molecular modification followed by reconstitution in an artificial blood formula. A strain of E.coli bacteria is taken and in three days the harvesting of protein is done along with the destruction of the bacteria. 

Then starts with the fermentation process where bacterial culture is transferred to the test tube containing all the required nutrients for growth. This step results in bacterial multiplication and transferring to a seed tank which later is transferred to a fermentation tank. This leads to the production of hemoglobin after which the tank is emptied and the isolation process begins. Here the hemoglobin is isolated with the centrifugal separator and purified by fractional distillation. Lastly from here, it is transferred for final processing. It’s mixed with water and electrolytes for the production of usable artificial blood which is later pasteurized and packaged.


The various types of artificial blood are restricted to certain limitations. Researchers and scientists are also coming up with the idea of using hematopoietic stem cells for the production of artificial blood. This is said to have similar morphology with a similar amount of hemoglobin as the natural red blood cells. The Food and Drug Administration is examining the safety of this blood along with its cost-effectiveness. It may also serve as a blood donor to all common blood types. Along with all this currently, many companies are working on the production of safe and effective artificial blood by clearing the various limitations. In the future, it is anticipated that new materials to carry oxygen in the body will be found. Additionally, long-lasting products will be developed, along with the products that perform other functions of the blood effectively. Hopefully, investigations carried out will be beneficial in the upcoming times.

Smart Inhalers

By Pratiksha Baliga

Published 1:57 PM EST, Sun May 9, 2021


Inhalers are medical devices used to treat chronic obstructive pulmonary disease such as asthma by delivering bronchodilator medication to the airway directly, making use of a fast and sharp inspiratory force, without passing through the blood. The medicine within inhalers uses lactose molecules. Chronic Obstructive Pulmonary Disease affects over 200 million people around the world whereas asthma affects another 300 million. The chronic respiratory disease makes up a little over 8% of the world’s chronic disease burden. In order to mitigate the clinical severity of these conditions, the patients have to adhere to a strict medication schedule, with the dosage and timing being adjusted to achieve control of their symptoms.

With modern times coming into play, inhalers are powered by different forms of technology giving rise to a new generation of devices named Smart Inhalers. They are present with extra digital features of connection with mobile applications and help doctors and patients to manage asthmatic conditions in a better and improved way. 

Working and Features

Monitoring of medication schedules and dosage reminders is its main feature. A sensor on the inhaler communicates with the mobile application via Bluetooth to keep a  track of the inhaler using data in the app. The app records the date, time, and even the location of each dosage intake, and then using this information schedules the user’s next dose reminder. Some of these inhalers use a built-in sensor that is integrated into the body of the inhaler itself, while others, for example, can use propeller sensors which are external sensors that can be attached to various kinds of inhalers. Along with these features these inhalers also have high pollen and pollution alerts or the ability to sense if the user forgets to take their inhaler with them when they leave home. They can also indicate when the patient is overusing their preventive medicine pointing towards poorly controlled asthma.

Nowadays a smart cap called CapMedic for smart inhalers is used by people with asthma, chronic obstructive pulmonary disease, and other respiratory disorders. It is available only by prescription. It has to be placed on top of the inhaler and it houses sensors that guide users and collect data for remote patient monitoring. It connects via Bluetooth providing direct communication with patients for better effectiveness in management. The caps are reusable and rechargeable emitting visual, audio, and haptic signals letting the users know when an inhaler has been adequately shaken and is fully upright, among other parameters that ensure a full dose of medication. It fits on most of the smart inhalers available and pairs with an app on the phone that can send data to a clinician. It also incorporates a spirometer which measures the air capacity of the lungs.

World’s First Smart Inhaler

The world’s first smart inhaler was recently approved by the FDA, and named Teva’s ProAir Digihaler (albuterol sulfate). It was introduced to the United States market through an sNDA application and was said to join Proteus Digital Health as being a potential game-changer for digital medicines.The ProAir Digihaler is built on the RespiClick inhaler formulation. It has a sensor that tracks when it is used in real-time and syncs this data to a mobile app. The patient has to use an app to scan a QR code at the top of the inhaler, which will sync the inhaler to the app. The ProAir Digihaler can determine how well the patient uses it, as the sensor measures a breath actuation and sees how well a patient inhales giving them a rating.

Patients can view their event data through the ProAir companion app, which provides tips to improve inhaler techniques and offers medication reminders if they choose. They can also transmit the data directly to their doctors to keep a track of their condition, its management and bring about improvement in their treatment plan.


Following the wave of connected devices and smart health technologies coming up in the healthcare sectors, the future of digital health innovation will be brighter than before. Smart inhalers are considered by many the way the future will progress, essentially breathing fresh air into the management scope of chronic respiratory treatments in the years ahead. Its demand is considered to increase at a significant rate with novel opportunities to address more challenges associated with accessibility, quality, effectiveness, efficiency, and cost of healthcare.

Asteroid Hyalosis

By Pratiksha Baliga

Published 7:18 PM EST, Wed April 7, 2021


The vitreous humour is a highly hydrated gel-like substance that provides structural support to the eyeball while providing a clear unobstructed path for light to reach the retina. It comes with hindrance to the forward oxygen diffusion from the retinal blood supply to the anterior segment of the eye where it can cause oxidative damage to the lens. It is an extracellular matrix composed of collagen fibrils with the carbohydrate polymer hyaluronan also called hyaluronic acid, serving as the major component between the fibrils. With age, it may partially liquefy as a result of hyaluronan breakdown associated with oxidative stress. Once liquefied the vitreous does not reform significantly. Opacities may form in the clear vitreous as a result of developmental abnormalities, injury, or diseases. Developmental opacities are present from birth and are remnants of the hyaloid system located in Cloquet’s canal.

Degenerative opacities are associated with inflammatory debris, often appear after ocular inflammation, ocular hemorrhage, posterior vitreous detachment, or vitreous hemorrhage.

One of such commonly observed degenerative opacities is Asteroid Hyalosis, a condition of the eye involving small white opacities of asteroid bodies or calcium fat globules in the vitreous humour. The asteroid bodies are chemically made up of calcium-pyrophosphates and phospholipids. These bodies remain attached to the collagen fibrils of the eye and move only with the movement of the collagen framework. The condition is considered to be degenerative as it is associated with increasing age usually 55 years and more commonly in males than females.

It occurs in only up to 0.2% of people under 55 years of age, while the prevalence in those 75 years or older is 2%-3%.

Fig: Asteroid Hyalosis

Fig: The yellow particles of Asteroid Hyalosis are seen over the optic nerve, which obscures the retina but vision is unaffected

Symptoms, Diagnosis, and Causes

It’s mostly asymptomatic and it does not affect the patients’ vision. It starts with the appearance of small yellow-white spots in the visual field of the patient, usually noticed during an eye examination by a specialist. The spots are very tiny and often hard to see unless observed closely under proper lightning. The white particles are composed of calcium hence to ease the eye examination the patient’s pupils are dilated using an instrument called a slit lamp. A special dye called fluorescein is applied with the administration of eye drops to dilate pupils to see the eye structures. In Asteroid Hyalosis asteroid particles would be visible through the slit beam.

Fig: Asteroid Particles in the vitreous cavity using Slit beam

Method of eye scanning can also be used called optical coherence tomography which will allow the eye specialist to visualize the retina layers in the back of the eye to create a cross-sectional retinal image. It can help provide an accurate anatomic diagnosis.

Fig: Optical coherence tomography appearance of Asteroid Hyalosis

Another method is Fluorescein Angiography which makes use of filters to reduce interference from the calcium bodies and makes diagnosis easier. However, this technique has limited ability to diagnose subtle abnormalities and often produces poor quality images. The requirement of high technical skill for handling the instrument is another challenge.

Fig: Fluorescein Angiography in Asteroid Hyalosis

Research believes that Asteroid Hyalosis is not associated with any particular eye disease but probably can be considered a side effect of certain eye procedures. The exact cause is unknown but it is believed that its association is with health conditions majorly diabetes mellitus. Patients with diabetes mellitus experience vitreous degeneration characterized by precocious liquefaction and posterior vitreous detachment. Biochemical studies have detected that hyperglycemia alters vitreous collagen, changes that might be responsible for the observed vitreous degeneration might cause asteroid hyalosis. It is considered to be unilateral but if it persists with health conditions like diabetes mellitus it should be bilateral because each eye is equally exposed to hyperglycemia.

The overall relationship between diabetes mellitus and asteroid hyalosis is further complicated by suggesting that asteroid hyalosis may arrest the process of vitreous collapse or eye contraction with proliferative diabetic retinopathy.


Asteroid Hyalosis doesn’t require any treatment unless it starts affecting a patient’s eye vision with being blurry/floaters or one has underlying conditions making your eye more vulnerable to damage such as diabetic retinopathy the vitreous humour can be surgically removed and replaced, a procedure of vitrectomy can be performed.

Fig: Procedure of Vitrectomy


The diagnosis and management of Asteroid Hyalosis are essential and should be done with utmost care. The associated health conditions, with the most common ones being diabetes mellitus, hypertension, and hyperlipidemia should be managed by interprofessional team communication with endocrinologists and general physicians along with optometrists, ophthalmologists, ophthalmology nurses, and operating room nurses. The nurses should be involved in the patient’s education and their follow-up, informing the ophthalmologist in case of any issue.

Einstein’s Brain

By Pratiksha Baliga

Published 9:53 PM EST, Sun February 28, 2021


Albert Einstein was a German theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics.

His brain has long been a subject of research and speculation. It was removed within seven and a half hours of his death by Thomas Harvey, a pathologist.

In 1955, Harvey decided to conduct an investigation of Einstein’s brain. He measured and took photographs of Einstein’s brain for further study. He divided Einstein’s brain into 240 blocks and created 12 sets of 200 slides containing tissue samples indexed to the blocks.

Scientific Study and Observation

Einstein’s brain weighed 1,230 grams (2.7lbs) which was less in comparison to a normal adult male brain, which weighs about 1,400 grams (3lbs).

In 1985, Dr. Marian Diamond received four cortical associated sections of the superior prefrontal and inferior parietal lobes of both the hemispheres of Einstein’s brain from Harvey. Glial cells (glue cells) fix neurons into place and keep them supplied with oxygen and nutrients. She made thin sections of the brain, 6 micrometres in thickness, to carry out microscopic examinations of these sections.

The number of neurons and glial cells were compared in four areas of the brain- Area 9 and 39 of the cerebral cortex on the right and left hemispheres in each area. Area 9 is located in the prefrontal cortex of the frontal lobe and is important for planning behavior, attention and memory. Area 39 is located in the parietal lobe, a part of the association cortex which is important for language and several other complex functions.

Dr. Diamond compared the ratio of the glial cells with that of 11 other males. It was observed that Einstein’s brain had more glial cells relative to neurons in all areas studied, which suggested that they needed and used more energy. 

In 1996, Britt Anderson at the University of Alabama at Birmingham published a study on Einstein’s prefrontal cortex. The thickness of Einstein’s cerebral cortex (area 9) was thinner than the normal brain but the density of neurons were greater. This suggested that the neurons were more tightly packed which might be the reason for Einstein’s faster processing of information.

In a normal human brain, the Parietal Operculum is a part of the parietal lobe that covers the upper part of the insular lobe from the front to the back. Harvey had reported that Einstein had no parietal operculum in either hemisphere, which was later disputed. An enlarged Sylvian fissure, a deep fissure in each hemisphere which separates the frontal and parietal lobes from the temporal lobe, was also found. In 1999, further analysis was done at McMaster University in Canada by Sandra Witelson in The Lancet, which revealed that his parietal operculum region in the inferior frontal gyrus, located in the frontal lobe of the brain, was vacant, and the Sylvian fissure was absent. Researchers theorized that this vacancy encouraged better communication of the neurons. This was considered the reason for Einstein’s spatial cognition and mathematical thought.

Examination of two slices of Albert Einstein’s brain was done containing the hippocampus, which is a subcortical brain structure containing neurons that plays an important role in learning and memory. The left sided neurons were larger than those of the right side in comparison with brain slices of the same area among ordinary people. Einstein’s left part of the brain had stronger nerve cell connections between hippocampus and neocortex as compared to the right.

In 2012, Dean Falk started working with a previously unseen set of photographs of Einstein’s brain taken by Harvey, in which she found many unusual features. One of which was an extra ridge on the mid-frontal lobe, which is concerned with planning and memory. In a normal brain, there are three ridges, whereas in Einstein’s brain, there were four, which justified that his grasping power and memory was slightly better compared to others. She also found that Einstein’s parietal lobes were dramatically asymmetric, and he had a knob on his right motor strip called the “sign of omega,” which is thought to be correlated with musicians who use their left hands and would apply to Einstein.

In 2013, Dean Falk studied Einstein’s unusual corpus callosum, a bundle of fibre which connects the two cerebral hemispheres and helps in communication between both the hemispheres. Einstein’s corpus Callosum was compared with that of 15 elderly people and 52 of the same aged people. It was found that Einstein’s brain had thicker corpus callosum than in control groups and had more connections between certain regions of his cerebral hemispheres in comparison to different and same aged people. This suggested enhanced cooperation between his brain hemispheres.


After carrying out the research of Albert Einstein’s brain, there is no clear conclusion that his mind has a significantly higher level of performance than the average humans. With each study and research in detail, the debated points have the equal potential to out-rule the other. Some points are confirmed while others are yet to be ruled out. Hopefully, the conclusion of this ongoing mystery will soon be discovered.

Overview of Eye Color Depictions


The coloured part of the eye iris has pigmentation which determines our eye colour. Pigmentation varies depending on the melanin concentration in the iris pigment epithelium, iris stroma (located at the back & front of the iris) and the cellular density of the stroma.[1]The darker the eye colour, the more melanin is present in them. According to many studies and new research findings conducted, it is observed that there could be a relationship between a person’s eye colour and personality traits. Europeans have found to have the greatest variation in eye colour with brown being the most common, blue/gray eyes coming up second and the most rare colour being green. Babies usually have blue eyes at first, but they later darken as melanin builds up in the iris. Eyes with the least melanin appear grey or blue, a moderate amount of melanin produce green eyes and those with the highest amounts are brown or black.The person’s eye colour indicates how agreeable that person is like those with lighter-coloured (blue and green) eyes tend to be less agreeable and more competitive than the brown-eyed. Blue and green eyes were also linked to being egocentric and skeptical of others while those with brown eyes were considered more selfless, sympathetic and willing to help others.[2]

Eye Colours and their Personality Traits

Brown eyes

Light to medium brown eyes is the world’s most prevalent eye color, with approximately 79% of the world’s population having them. They tend to be confident, assertive & are great at handling conflict because they are typically agreeable people who are willing to listen to other people’s points of view before giving their own. Chronobiology International published a study which showed that they tend to sleep two hours less than those with light-coloured eyes hence have poorer sleep cycles,thus having a harder time waking up in the morning.Researches particularly one conducted at Georgia State University, say that the melanin causing the brown hue in the eyes makes people more receptive to alcohol and are more likely to be alcoholics. But the later research has shown the opposite to be true.Dark-brown eyes are usually highly pigmented with more melanin, sometimes causing them to look nearly black, since darker the eyes the more melanin is present. They share many of the same traits with light brown eyed people but are more confident than them. They are natural leaders who are mysterious.They tend to drink less than those with lighter eyes. They don’t follow the crowd but the crowd follows them. They are better in sports, requiring hitting targets like tennis.[3]

Black eyes

People with Black eyes are considered to be strong, full of energy, impulsive, often seek dangerous adventures, exhibit great dignity but pretentious, and are secretive and mysterious. They are also very passionate and loyal especially to their friends.[3]

Green eyes

Only 2% of the world’s population have green eyes.The balance of melanin in green eyes contributes to a mix of brown eye and blue eye personality traits. Green eyed people are the most exotic and seductive ones,mysterious with a self-sufficiency attitude, often unpredictable,yet slow to anger. They have a melanin balance which keeps them agreeable yet dominant and strong. They are patient, can restrain their emotions, are original, creative, highly intelligent, intellectual,have a high level of concentration and enjoy freedom.They are considered mysterious,nature admirers and have a positive and creative outlook towards life. Also very jovial, and can easily become jealous but possess lots of love. They are generally sensual and attractive.[3]

Gray eyes

Gray eyes are a sign of a person who obeys society’s standards while being quiet and deceptive.[5]This eye color is a variation of blue eyes and is extremely rare which is 1% of the world population. If one has gray eyes their personality traits vary depending on whether it is dark or light gray. Light gray eyes have much less melanin than dark gray eyes. Those with light gray eyes won’t let just anyone in but once they do, they open up completely and great affection. Whereas Dark gray eyes have a balanced personality with two separate sides, sometimes good and sometimes bad depending upon the situation.[3]

Blue eyes

8-10% of the world’s population are blue eyed, and are considered to share a single ancestor in common.The light blue hue of this eye color is sometimes associated with being soft and timid but they are considered to be the strongest of all as they are better able to tolerate pain than those with any other eye color. They know how to manage their emotions and can handle the negative ones very well as they possess inner and physical strength.They are considered a representation of knowledge,attractive,possessing a peaceful and calm personality. They are considered to exceed expectations especially in academic sciences.[4]

Violet eyes

People with violet eyes are highly imaginative, creative, possess lots of self-esteem,  and are often a perfectionist with high ideals and a high charisma.[3]

Amber eyes

According to researchers Amber eye colour in humans is the rarest (0.01%) which are of solid colour and have a strong tint of yellowish or golden with a copper tint due to deposition of a yellow pigment called lipochrome in the iris. It is a very fascinating eye colour to have because of the mystic personality and aura they carry. Such people are crowd pleasers. They are mistaken to be reserved but in reality they are very warm, charming and a great conversationalist. They are also unique, creative, innovative, trustworthy, like being outdoors and are appealing to others.[3]

Hazel eyes

The unique coloring of hazel eyes is a result of the combination of brown and amber with a unique scattering of light due to materials from the bloodstream that were broken down due to liver imbalance thus might experience digestive issues.They often appear to change colors; more green, amber, or brown depending on their environment. Only 5%of the world’s population have hazel eyes and that goes perfectly with their personality. Hazel eyed people are rare,hard to describe and have a balanced attitude.They are imaginative, determined, love adventures, and often have a boundless inner vitality. They are often risk takers, profound thinkers, courageous, aware of their own limitations, responsible but often have a serious selfish attitude.Two hazel eyes are never exactly the same just like their unique eye colour scheming,thus hard to pinpoint their exact trait.[3]

Our eyes are not only the windows to our soul but also to our personality.The pigmentation of our iris influences the way one acts, the things one likes and overall how a person is.Our eye colour always reflects our inner feelings of joy, happiness, compassion, patience, frustration, pain and anger. There is surely a connection between personality traits and iris characteristics which suggests that people with different eye colors tend to develop distinctive personality traits based on eye colors.

Botulinum Toxin A: A Guide Towards Enhancing One’s Features


Signs of aging start to appear on every person no matter how young the person is. One must have probably heard the term facial aesthetics either in terms of the overall attractive level of someone’s face or the set of treatments available to help people enhance their features and allow their natural beauty to shine through. These treatments often make use of Botox to soften expression lines and define facial contours adding a glow to one’s face.[1] Botox is considered the best treatment and involves using a purified version of the botulinum type A toxin to reduce unwanted lines and wrinkles on the face restoring a more youthful appearance.[2] 

The face has sets of muscles that contract due to everyday facial expressions which leads to the skin wrinkles as the muscle shortens during contraction, making it move in different directions.

Botox best targets Dynamic wrinkles which are formed by facial movements, such as squinting, smiling and furrowing of the brow. A tiny injection of Botox in the right place weakens the muscle, allows it to relax, and thereby removes the wrinkle.

Along with maintaining wrinkles, it helps in slimming and contouring the face which is achieved by targeting the masseter muscles at the back of the jaw giving a proper square shape to the face. This is called as the masseter reduction. This reduction results in loss of pounds of weight making one’s face look elegant, thus maintaining facial balance which must be enhanced from time to time.

Mechanism of Action

Botulinum toxin is a two-chain polypeptide consisting of a light chain (approx 50 kDa) and a heavy chain (approx 100 kDa) which are joined by a disulfide bond.[4]This toxin binds to specific receptors on the surface of the presynaptic nerve cells, mediated by the C-terminal of the heavy chain, which takes around half an hour. The plasma membrane of the nerve cells invaginates around the toxin-receptor complex, forming a vesicle containing a toxin in the nerve terminal, the process is known as internalization. Following internalization, is the process of Translocation in which the disulfide bond is cleaved and the 50-kDa light chain of the toxin is released across the endosomal membrane of the endocytic vesicle into the cytoplasm of the nerve terminal.[3]Botulinum toxin can be serologically divided from A to G[4]. The light chain of serotypes A and E inhibit the release of acetylcholine by cleaving the cytoplasmic protein needed for the docking of acetylcholine vesicles on the inner side of the nerve membrane of the nerve terminal[3], thus leading to blocking of the nerve impulses to the tiny facial muscles, forcing them to relax and smoothing out the skin to lessen the appearance of lines and wrinkles.[2]. Following the injection, the toxin diffuses into the tissue until it binds selectively and reversibly in the presynaptic terminal of the neuromuscular junction and then attaches to the specific protein-membrane responsible for acetylcholine excretion.[3] 

Botox is generally injected into the muscles of facial expression which are attached to muscles rather than bones and by contracting, they pull across the skin to give facial expressions.[5]

The After Effects and Precautions

The clinical effects of Botox are seen on the first to the fourth day after injection followed by 1 to 4 weeks of maximum effect, which will resolve after 3–4 months. The effects are temporary and remain maximum for around 6months. In order to prolong its effect from six months to one year, the treatment should be repeated for one year or more. The duration of the Botox effect varies among individuals due to differences in muscle arrangements. According to the American Board of Cosmetic Surgery, Botox injections are the most popular cosmetic procedure nationwide.It is used for reducing glabellar frown lines, crow’s feet at the side of the eyes, horizontal forehead creases, wrinkles around the mouth, nasolabial folds, smoothing out neck and chest or cleavage wrinkles. The procedure takes around 15 to 30 minutes and effects are fully visible in around 7-14 days. Some measures should be taken into consideration before and after the procedure. It’s best to avoid alcohol starting one week before the procedure. One should discontinue medications like Aspirin and anti-inflammatory ones before 2 weeks of the procedure to avoid bruising. After the procedure, one should prefer not to rub on the injection site for at least 24 hours to avoid the spread of Botox to another area. The doctor also advises to stay upright for about 4 hours after the procedure and take a day off from exercising. Like every other treatment, Botox has some advantages along with that some disadvantages also. The disadvantages include crooked smile or drooling, eye dryness or severe tearing, mild pain or swelling around the injection site, weakness in the muscles,flu-like symptoms or a feeling of being unwell, upset stomach, numbness.[5]

Ideal Age

This depends on the benefits of BOTOX on our skin.More sun damage may lead to start treatments in  late twenties to early thirties, while different skin types or lucky genetics could allow one to wait until age 40 or above.

Botox in 20’s: During this age if one has smooth and wrinkle free skin they may go with less or no Botox.If exposure to the sun is more or use tanning beds, are a smoker, or showing early signs of wrinkles due to family tendency, then one must consult a dermatologist for light Botox.

Botox in 30’s: In one’s 30’s firstly the sun exposure is the most important factor common in all age groups. More refined wrinkles may start appearing at this age so this is the best age for Botox treatment. Also if one is a smoker or live in higher altitudes, in such conditions strain on skin is more  thus Botox is the best at this time.

Botox in 40’s: At this time wrinkles are more defined as the skin starts thinning along with the breaking down of the elastin and collagen start becoming more visible. Once the wrinkle lines have etched in and are visible at rest and even remain when one stretches their skin with their fingers, it’s an indication of the ideal age group for Botox.[6]


For many generations, a lot of people have benefited from BOTOX Treatment. Not only it is highly effective for smoothing wrinkles and reducing fine lines but is also used as a facial relaxation treatment which also aids in treating disorders like eye-twitching, hyperhidrosis, and certain cases of Bell’s Palsy. An injection of Botox temporarily prevents muscles from moving and blocks certain chemical signals from nerve endings. This can relax the skin around the area and relieve pain or discomfort from spasms treating eye twitching. They make use of botulinum toxin to block the nerve signals responsible for sweating, stopping the sweat glands from producing too much sweat thus treating hyperhidrosis. A Botox treatment for permanent or longstanding Bell’s palsy is available to help patients mitigate the effects of unilateral facial weakness. It relaxes hyperactive muscles and temporarily restores facial symmetry, resulting in an improved facial appearance.

Botox injections have been widely acclaimed for their short-term, anti-ageing properties. The procedure has gained popularity as it is non-invasive, leaves no scars and the recovery period is low. However it should be remembered that Botox is an addiction inducing substance and its patrons may become heavily dependent on the drug to make one look young and feel good.

Telemedicine: A Virtual Visit


Telemedicine is the use of electronic communications and software by health care professionals to evaluate, diagnose, and treat patients at a distance. It includes a growing variety of applications and services using two-way video, e-mail, smartphones, wireless tools, and other forms of telecommunication technology. Patient consultations through video conferencing, transmission of still images, e-health including patient portals, remote monitoring of vital signs, continuing medical education are all considered a part of telemedicine.


During the admission of a patient to a hospital, the patient along with the family members have to bear a lot of expenses like traveling, medicine, and the stay in the hospital till the treatment is completed. Telemedicine provides a means to reduce this expenditure by contacting the doctors through electronic devices from their current location. The doctors can schedule appointments that notify the patient and give guidelines along with additional advice like curbing obesity rate and tobacco use by encouraging them to improve their lifestyle choices. It ensures regular follow-ups, reporting early warning signs even if the patient is in any part of the world. Proper and remote monitoring of the patient can be done along with solving queries to ensure they are on track. When patients are committed to their own healthcare goals, it leads to lower costs and improved health. Some studies also reveal that telemedicine patients score lower for depression, anxiety, and stress and have 38% fewer hospital admissions. In a doctor’s clinic or hospital, there are a lot of chances of transmission of infections or diseases from patient to patient or patient to doctor. By telemedicine, the risk of exposure and infection transmission is reduced.

It is also beneficial for the doctors, especially the primary care ones, to contact specialists irrespective of their location and communicate easily for a second opinion and detailed advice. This benefit provides improved access and consultation for better treatment. Telemedicine comes into play in a clinic setup where the doctor has a lot of overhead expenses like buying a clinic or if rented then paying the rent to the owner, examination beds for patient’s checkup, the need of various types of equipment and staff members for managing the clinic. Through telemedicine, the doctors can reduce this extra cost by attending most of the patients online who do not require a physical approach. This aspect ensures increased patient flow and revenue to doctors and reduced transport expenditure to the patients making it beneficial for both the doctors and the patients.


During the scheduled appointment the patient can have any of their family members present with them. If the age of the patient is 16 years or less, or if the patient has some mental conditions like dementia or physical disability due to an accident, then any one of the authorized family members is required to consult the doctor on the patient’s behalf, irrespective of the patient’s presence. At the time of the virtual visit, the doctor must first ensure the consent of the patient before proceeding with the consultation. Then the patient has to provide the doctor with their medical record, enumerating their present condition and the current symptoms to proceed with the best treatment according to the doctor’s advice. The doctor should evaluate and make a decision regarding the preferable consultation medium. Like in cases of appendicitis complaint physical examination is needed and telemedicine cannot be applied. A complaint of headache or fever may not always require a physical examination or audio-visual approach. But in cases of any allergy or any inflammation like Conjunctivitis, the doctor has to decide if a physical or telemedicine approach is needed. During the telemedicine visit disrobing of the patient is mostly never preferred unless there’s an utmost need or in a case where the patient wants an examination of a visible finding concerning them. In such a situation the patient can click a photo of the visible finding and send it to the doctor for the diagnosis. In a telemedicine setup, the first doctor patient consultation need not be an in-person consultation and the doctors can be contacted by the patients from any state. The doctors giving teleconsultation must be a registered practitioner with a degree of MBBS and above. The displaying of their registration number during all the consultation is necessary especially in cases of emails, Whatsapp messages, prescriptions, and on fee receipts.

If the teleconsultation with the patient does not take place over video, then the doctor cannot prescribe any drugs to the patient other than common over-the-counter medications such as paracetamol, O.R.S. solutions, cough lozenges, etc. 

Prescribing drugs for chronic diseases like asthma, diabetes, hypertension should be avoided in telemedicine consultation unless it is an addition to the earlier prescription of an in-person consultation of approximately less than six months ago. If a prescription is necessary then the teleconsultation should be done strictly via video. A prescription can be sent through any electronic medium such as email, Whatsapp as a photo, scan, or digital copy of a signed prescription or an e-prescription.


Telemedicine applications are used for delivering virtual health services from providers to patients. They include all-in-one software platforms to video chat and beyond some of which are widely in talks.

MD Live is an app that provides 24/7 access to doctors, dermatologists, psychiatrists, and counselors who are board-certified with an experience of 15years and above through a mobile app or an online website. Pieces of Advice for routine medical conditions like allergies, common cold, diarrhea, flu are given by well-trained physicians and treatment of depression, anxiety, eating disorders by psychiatrists.

Doctor on demand is being widely used especially in the United States to improve its healthcare system. The main advantage of this is it will reduce the waiting time of the patients who wait for almost 24days and above for the first appointment with the doctor and can connect face to face with doctors and specialists from multiple medical branches. It is free to join and payment is as per consultation which is proven to treat 90% of the common health issues.

Live Health ensures expert medical advice, diagnosis, treatment plans, and prescriptions along with the detailed profile of each doctor giving the choice to choose the doctor of one’s choice according to one’s needs with quite an affordable price.

Talkspace is known for its services to psychiatry and emotionally challenged patients. One can have unlimited talks and also send unlimited messages to your therapist within the privacy of your room and get one to two times messages reply per day. If one needs unlimited chats to get out of their rough times Sibly can also be one’s choice.

Teladoc is said to be ranked at the topmost for telemedicine services in Satisfaction and Customer Service with Direct by J.D. Power. It is also known to be working with 5% of the top-ranking medical specialists. It provides various services like everyday care, behavioral health, dermatology, nutrition, and women’s health doctors, integration with Apple HealthKit, e-Prescriptions, and video conferencing.

Fruit Street especially works on diabetic patients and patients aiming for weight loss. It notifies the patient at the start if they are fit for the program. It is a 12-week program with 26 video chat courses by a registered dietician. Along with the general services of telemedicine apps it has an additional feature of providing a free Fitbit for attending two classes.


Information and Communication Technologies has had a positive impact on the healthcare sector with the innovation of telemedicine in recent times. This impact is not only from a technology point of view but also from a socio-cultural and economic view. The reason lies upon various solutions of day to day challenges such as the demand for healthcare services, population aging, or management of large amounts of information. It is providing a convenient way to deliver and improve access to healthcare for non-emergency issues by saving time and money through online consultation. Thus, telemedicine technology is becoming a viable alternative to an in-person doctor visit.

Artificial Intelligence in Medicine

Artificial intelligence in medical practice is the use of computer techniques to perform clinical diagnoses and suggest treatments in medical areas [1]. It has the capability of detecting meaningful relationships in a data set and could be used for the diagnosis, treatment, and for coming to a particular conclusion. Similar to the way doctors are educated through years of medical schooling and learning from mistakes, artificial intelligence algorithms learn to do the same job as a doctor. They perform tasks requiring human intelligence like pattern and speech recognition, image analysis, and decision making. The Artificial Intelligence algorithm includes feeding data in the computer system, which are structured having a label recognizable to the algorithm, performance is analyzed just like exams give an analysis of a medical student’s performance thus giving results. Based on the results of this analysis the algorithm can be modified, fed more data, or rolled out for the decision-making of the person writing the algorithm [2].

Fig: AI algorithm learning the basic anatomy of a hand and can recreate where a missing digit should be. This could allow physicians to see the proper place to reconstruct a limb/put a prosthetic.

These performances and results are tested with a physician’s performance to determine its clinical ability and value. In medicine language, it includes input data based upon numericals such as Heart Rate or Blood Pressure and based upon images such as Magnetic Resonance Imaging Scans or Images of Biopsy Tissue Samples. The algorithms from this data could be a probability or a classification. The result of the above example could be the probability of having an arterial clot according to the heart rate and blood pressure data or the labeling of an imaged tissue sample by classifying it as cancerous or non-cancerous. There are two recent applications in the Artificial Intelligence of clinical and accurate algorithms benefiting both patient and doctor for the diagnosis. One is the algorithm researchers at Seoul National University Hospital and College of Medicine developed called Deep Learning-based Automatic Detection to analyze chest radiographs and detect abnormal cell growth (cancers). The results were compared to many physician’s detection abilities and were found to perform better than the doctors [2].

Fig: Artificial Intelligence algorithm; Deep Learning Method.The left panel shows the original X-ray. The right panel shows the X-ray with orange color indicating signs of pneumothorax which could be unnoticed by radiologists

The second algorithm was developed by researchers at Google AI Healthcare called Lymph Node Assistant which analyzed histology slides stained tissue samples to identify metastatic breast cancer tumors from lymph node biopsies. It could identify suspicious regions of the sample which could not be distinguished with the human eye. It was proven to accurately classify a cancer as cancerous or non-cancerous in 99% of the cases. Hence these algorithms could help doctors with correct diagnosis thus allowing them to invest time in solving cases that computers cannot solve [2].

Fig: AI algorithm; Lymph node biopsy

Artificial intelligence could be considered a boon as it may help for early diagnosis of diseases whose later diagnosis can cause delays in the treatment and may be harmful to the patient. For example, researchers have claimed that it could be used to diagnose Alzheimer’s disease years before symptoms appear. The computers can be trained for brain scans to be able to spot subtle signs of dementia that could be missed by humans allowing early diagnosis. This could probably be done using 18-F-fluorodeoxyglucose positron emission tomography (FDG-PET). In an FDG-PET scan FDG, a radioactive glucose compound is injected into the blood. PET scans can then measure the uptake of FDG in brain cells, an indicator of metabolic activity. Through Deep Learning, the algorithm can teach itself metabolic patterns that correspond to Alzheimer’s disease.If one can detect the symptoms earlier, it would help investigators to find better ways to reduce or halt the disease process. Future research should take into consideration, training the deep learning algorithm to look for patterns associated with the accumulation of beta-amyloid and tau proteins, abnormal protein clumps, and tangles in the brain that are markers specific to Alzheimer’s disease, according to UCSF’s Youngho Seo, Ph.D., which can add another dimension to using Artificial Intelligence in Alzheimer’s disease detection [3].

Artificial Intelligence has many clinical applications to improve patient care and potentially save lives. Maintaining medical records and past history is the first step in health care where robots collect, store, reformat, and trace data to provide faster and more consistent access. They also analyze data including notes and reports from a patient’s file and clinical expertise to help to choose the right treatment pathway [5].There are some latest tools and technology developed in the health care sector based on the Artificial Intelligence algorithm. This includes: MelaFind, which is a tool that does not involve introduction of instruments into the body and gives extra information to dermatologists in early detection and recognition of skin cancer,lesions and helps in it’s examination. It also helps in evaluation of skin lesions up to 2.5 mm beneath the skin. By using Artificial Intelligence based algorithms, dermatologists can analyze irregular moles and diagnose serious skin cancers such as melanoma. The device demonstrated 98.3% sensitivity by correctly identifying 172 out of 175 melanomas and high-grade lesions. Robotic-assisted therapy is used in neurological patients and is specially used for stroke patients’ recovery. The robotic arm and hand use digital algorithms to detect motions that patients cannot execute during therapy thus improving their performance per hour than they would have if worked with a physical therapist alone thus allowing speedy recover[4].Robots can also perform tests, x-rays, CT scans, data entry, and other tasks faster and more accurately. Cardiology and Radiology are two fields where the amount of data to analyze is huge and time-consuming. Future cardiologists and radiologists should look only at the most critical cases in which human monitoring is useful [5]. Caption Guidance, which is an Artificial Intelligence guided ultrasound platform or software capable of instructing clinicians on obtaining a clearer picture of the heart in motion. It will be used for capturing echocardiographic images of the patient’s heart without special training, spotting high-quality 2D heart images, and automatically recording video clips for later analysis, while calculating heart function measures thus improving the diagnosis of heart diseases [4].

Fig: AI tools in health care

Conclusion: Artificial Intelligence will surely improve the healthcare industry, from predictive medical care and more accurate diagnosis to motivating the patients to take care of their health. It will certainly continue enhancing the patient’s experience and healthcare expertise in general. The use of Artificial Intelligence is predicted to decrease medical costs as there will be more accuracy in diagnosis and better predictions in the treatment plan as well as more prevention of disease. It will not replace healthcare workers but instead allow them to spend more time for the bedside care of their patients, resulting in the greater outcomes for all.
