An injectable drug, called ATX-101, currently being tested melts away "submental fat", better known as the double chin. According to its makers, ATX-101 can be injected in a clinic and takes just five minutes. It consists of deoxycholic acid, a naturally-occurring molecule that helps us break down fat, which effectively destroys the membranes of fat cells, causing them to burst and then be metabolised by the body. ...

A possible vaccine for lung cancer! In a country known for cigars, lung cancer is one of the major killers in Cuba. So for the past 25 years, they’ve been developing Cimamax, which is now available freely to Cubans. According to a Phase II trial conducted in Cuba in 2008, lung cancer patients who received the vaccine lived an average of four to six months longer than those who didn’t. This led Japan and some European countries to trial the drug as well.

The drug itself is far from flawless and, by attacking a cell’s protein rather than the tumour directly, can have severe side effects, including – of all things - causing a higher risk of cancer. It might not be a "cure" in the traditional sense, but it's a way of managing the disease. What t ...

Isn't it strange, two FDA-approved drugs - topical ruxolitinib or tofacitinib - can reawaken dormant hair follicles! According to the study, within 3 weeks, mice that received topical ruxolitinib or tofacitinib had regrown nearly all their hair (right photo; drug was applied only to the right side of the mouse). Little to no hair growth occurred in control mice during the same timeframe (left photo). According to researchers at Columbia University Medical Center, inhibiting a family of enzymes inside hair follicles that are suspended in a resting state restores hair growth.

These drugs, known as JAK inhibitors have been approved to treat blood diseases (ruxolitinib) and the other for rheumatoid arthritis (tofacitinib). Both are being tested ...

For the first time, scientists have discovered a link between heavy marijuana use and reduced dopamine production. Just so you know, dopamine is the hormone/neurotransmitter that is released during any kind of satisfaction - it's the same hormone that is released in your brain when you eat chocolate. In a recent study, lower dopamine release was found in the striatum - a region of the brain that is involved in working memory, impulsive behavior, and attention, in addition to subregions involved in associative and sensorimotor learning, and in the globus pallidus. Previous studies have shown that addiction to other drugs of abuse, such as cocaine and heroin, have similar effects on dopamine release, but such evidence for cannabis was mis ...

Asthma is one of those illnesses that is so common that we never stop to question what causes it and how it could be treated. Affecting more than 25 million people, asthma is one of the most common chronic respiratory conditions in the United States. It is caused by the increased reactivity of the tracheobronchial tree to various stimuli, including exercise, allergies, or infections of the respiratory tract. Symptoms include, but are not limited to breathlessness, cough, wheezing, and chest tightness.


The most commonly used medications for asthma are: bronchodilators, xanthine derivatives, leukotriene inhibitors, corticosteroids, and mast cell stabilizers (see full list below). Xanthine derivatives treat asthma by re ...

For quite some time it's been known in the medical community that a link exists between depression and heart disease. For example, large epidemiological surveys typically find that 1.5 to 3 percent of the population is depressed at any given time. Among patients with heart disease, however, the rate of depression is closer to 18 percent. Similarly, about 1 in 6 people in the general population has an episode of major depression during their lifetimes, compared to about 50 percent of people with heart disease. Finally, a Canadian study revealed that of 222 patients who had suffered heart attacks, those who were depressed were four times as likely to die within the next 6 months.

Amassing this evidence is one thing, but explaining it is quite ...
