Exposure to high altitude can cause acute mountain sickness (AMS) and, in severe cases, cerebral or pulmonary edema. Capillary leakage has been hypothesized to play a role in the pathogenesis of AMS, although the mechanism of altitude-related illnesses re
Around half of people with an extreme form of obsessive compulsive disorder responded well to a type of psychosurgery that proved to be safe and effective, according to new research.
Stem cells that strongly express a gene called WNT3 are biased to develop into cells and tissues including pancreas, liver and bladder. This discovery suggests that other genes may serve as biomarkers for selecting stem cells with a preference for turning
Another piece of the puzzle to better understand and treat obsessive compulsive disorder (OCD) has fallen into place with the publication of new research that shows that the structural brain abnormalities of Doberman pinschers afflicted with canine compul

New research suggests that the altered function of neural circuitry contributes to restricted eating in anorexia and overeating in bulimia. The research may offer a pathway to new and more effective treatments for these serious eating disorders.
Researchers have identified the microenvironment surrounding microvasculature as a niche where dormant cancer cells may reside, and the sprouting of microvasculature blood vessels as the event that transforms dormant cancer cells into metastatic tumors.
Cancer immunotherapy is showing promise in treating patients with a variety of advanced, metastatic tumors, as evidenced by two newly unveiled studies.
One of the most difficult moments faced by anaesthetists and other healthcare staff is when to carry on attempts to resuscitate a person, and when those efforts should reasonably stop.
Different forms of childhood abuse increase the risk for mental illness as well as sexual dysfunction in adulthood, but little has been known about how that happens. Scientists have now discovered a neural basis for this association. The study shows that
Any breast cancer surgeon who regularly performs lumpectomies confronts the question "Did I get it all?" 30 to 60 percent of the time in the US, the answer is "no," requiring the patient to undergo a second surgery to remove the remain
Intestinal bacteria may have a greater influence on us than was previously thought. Researchers have shown that patients with type 2 diabetes have an altered gut microbiota. Their findings have led to a new model to identify patients at increased risk of
The liver can indeed regenerate itself if part of it is removed. However, researchers trying to exploit that ability in hopes of producing artificial liver tissue for transplantation have repeatedly been stymied: Mature liver cells, known as hepatocytes,

Researchers report preliminary results showing significant antitumor activity with very manageable side effects from a new drug being tested in patients with advanced melanoma, the deadliest form of skin cancer.

Researchers have determined the role of a key growth factor, found in limited quantities in human skin cells, that helps hair follicles form and regenerate during the wound healing process. When this growth factor, called Fgf9, was overexpressed in a mous
In an age when microbial pathogens are growing increasingly resistant to the conventional antibiotics used to tamp down infection, scientists have synthesized a potent new class of compounds capable of curbing the bacteria that cause staph infections.

A new report from the Institute of Medicine says schools should be responsible for helping pupils engage in at least 60 minutes of vigorous or moderate intensity activity during each school day.
A frequent history of heartburn elevated risk for throat and vocal cord cancers. Use of antacids lowered risk. Further studies are needed to confirm the protective effect of antacids.
