Melatonin as a neurotransmitter

Neurotransmitters are chemical messengers which facilitate communication between neurons and from neurons to the brain. Melatonin is one example of these neurotransmitters. Melatonin acts as a neurotransmitter responsible for regulating circadian rhythms and affecting the sleep-wake cycle. The production of melanin is influenced by the body’s internal clock, which responds to light and darkness exposure.

Melatonin is a central player in the regulation of the circadian rhythm, which helps to synchronize your body and its sleep cycle along with the day-night cycle. It is typically released in the evening or long bouts of tiredness, which signals the body that it is time to go to sleep. Melatonin is usually released and linked to the eye’s exposure of darkness. As the daylight diminishes, melatonin levels in the blood rise steadily, which promotes drowsiness and thus signals the transition to a sleepy phase.

Melatonin works in a rather simple way. Its sleep-inducing effects are administered based on its interaction with melatonin receptors, particularly MT1 and MT2 receptors in the brain. When they are activated, they promote sleep.

Melatonin Supplements are administered to people who have problems with their sleep cycle and are unable to feel well-rested or sleep on time. These supplements work by mimicking natural melatonin production in the body, as they follow a natural rise pattern in response to decreasing light levels. They are sometimes also used to alleviate jet leg and to support working personnel who work in night shifts.

The top 4 diets for PCOS: DASH diet, high protein diet, reduced calorie diet, and the keto diet. Which is better?

 PCOS is a  condition wherein people have imbalanced hormone levels. These imbalances present themselves in the form of polycystic ovaries, chronic irregular periods, and higher levels of testosterone in the form of increased body/facial hair. Among people who have PCOS, 80% of patients will hold fat around their belly and gain weight because of the effects of hormonal imbalances on their bodies. These effects include insulin resistance, gut dysbiosis, low-grade inflammation and more.  To treat this weight gain, doctors tend to recommend different diets to PCOS patients. But, the efficacy of these diets are heavily dependent on the person's individual situation. There are four major dietary approaches used to lose weight for people with PCOS: Reduced calorie diets, DASH diets, high protein diets, and keto diets. For most people, a combination of all of these diets will work best.  Here's a short explanation of each of these diets:  1) Reduced calorie diet: You e...

Eliglustat for Gaucher disease: How does it work? How is it consumed? Side effects? Is it safe? Efficacy? Research? Evidence?

Gaucher disease is a rare genetic disorder wherein the body lacks the ability to break down a specific kind of fat, which leads to accumulation thereof around various parts of the body, such as organs and bones. Eliglustat is one of the most common medications prescribed to help treat the disease by reducing production of the fat itself.  The disease is an inherited lysosomal storage disorder which is caused by an enzyme deficiency, specifically a low level of glucocerebrosidase. This enzyme breaks down a fat with a similar name, glucocerebroside. When the body lacks production of the enzyme, the fat accumulates around and in cells of the spleen, liver, and bone marrow. This causes a variety of symptoms in patients, and can present itself in bizarre ways like: enlarged spleens and livers, increased bone pain and occurrence of fractures, fatigue, anemia and even increased bruising.  Eliglustat, the medicine provided to patients, works in one way: substrate reduction. Basically,...

How does oxymetazoline work to clear your nasal passages?

Oxymetazoline Hydrochloride is a topical nasal decongestant that is often found in most OTC nasal sprays like Otrivin in India. It works quite effectively with regards to relieving people from nasal congestion caused by things like colds, allergies, or sinusitis by constricting blood vessels in the nasal passages. The medication is an alpha-adrenergic receptor binder, meaning that it binds to the alpha-adrenergic receptors. These receptors are found on the smooth muscle cells which line blood vessels in the nasal mucosa. When oxymetazoline is applied to the nasal mucosa through droplets, it stimulates the receptors and triggers them to cause constriction of nasal blood vessels. Through vasoconstriction, there is a reduce in blood flow to the region, causing decreased swelling and inflammation. It also reduces how much mucus is produced, since it reduces the quantity of fluid that leaks into the passages. Thus, air can flow more freely in the passage, providing relief from the blocked n...
