Bright light therapy may aid patients with depressive and bipolar disorders

A report in the November Cell Metabolism reveals powerful effects of light on the adrenal glands, a finding that might explain the broad benefits of bright light therapy for a variety of conditions, including sleep and depressive disorders, according to researchers.

Circadian rhythm - two key groups of neurons control morning and evening activity

A Brandeis University study published in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies).

Biomedical device allows stem cells derived from adult bone marrow to be grown in sufficient quantities to permit far more research

Human stem cells offer tremendous hope for the development of revolutionary medical treatments for these and a variety of other human health problems.

Discovery of novel form of regulation of the GLI1 gene

The Quaking gene, first described as a mutation in mice that causes rapid tremor, is thought to suppress tumor formation and protect humans from cancer.

Molecular origins of diabetes

An unexpected twist to a discovery reported just two months ago may significantly improve our understanding about the molecular origins of diabetes.

First step in exploring the GnRH reproduction-related circuitry in the brain

Howard Hughes Medical Institute researchers have discovered a vast network of neurons in the brain of mice that governs reproduction and controls the effects of reproductive status on other brain functions.

Researchers can now identify patients likely to respond to cancer drug therapy

Researchers at UCLA's Jonsson Cancer have identified key characteristics in certain deadly brain tumors that make them 51 times more likely to respond to a specific class of drugs than tumors in which the molecular signature is absent.

How protein-enriched meals decrease hunger and reduce eating

Researchers have uncovered new evidence to explain the observation that diets rich in protein stunt the appetite, according to a report in the November Cell Metabolism.

Lifelong exercise decreases cellular aging in the brain

In the first study to show that lifelong exercise decreases cellular aging in the brain, scientists from the McKnight Brain Institute of the University of Florida say that moderately active rats have healthier DNA and more robust brain cells than their less active counterparts. The research was presented at the Society for Neuroscience's 35th annual meeting in Washington, D.C.

Cellular signal may determine life or death for damaged brain cells

Scientists at the Universities of Heidelberg and Ulm and a unit of the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, have discovered that a specific signal within brain cells may determine whether they live or die after a stroke.

Pretreating a vein graft with edifoligide prior to coronary bypass graft surgery does not lower the rate of graft failure

Coronary artery bypass graft (CABG) surgery is one of the most common surgical procedures performed in the United States, according to background information in the article. In appropriately selected patients, CABG surgery results in improved survival, relief of angina, and improved quality of life. Despite frequent use of artery grafts, vein grafts remain the most frequently used conduit.

Zyflamend shows promise in the early treatment of prostate cancer

Data from the Columbia University Department of Urology demonstrates that Zyflamend, a unique herbal extract preparation, suppresses the growth of prostate cancer cells and induces prostate cancer cells to self-destruct via a process called "apoptosis."

Human umbilical cord blood cells may widen treatment window for stroke

An experimental treatment that spares disability from acute stroke may be delivered much later than the current three-hour treatment standard – a potential advance needed to benefit more stroke victims.

Older brains store and encode memories differently than younger brains

Researchers working with rats have found the first solid evidence that still "sharp" older brains store and encode memories differently than younger brains.

Aspirin and ibuprofen may significantly reduce the risk of esophageal cancer among people with Barrett's esophagus

Aspirin and other nonsteroidal anti- inflammatory drugs, such as ibuprofen, may significantly reduce the risk of esophageal cancer among people with Barrett's esophagus, a precancerous condition associated with chronic heartburn that affects an estimated 1 million to 2 million Americans.

Introgen's INGN 241 combined with Celebrex kills breast cancer cells

Introgen Therapeutics, Inc. today reported the publication of preclinical data demonstrating that INGN 241 works synergistically with celecoxib (Celebrex) marketed by Pfizer to inhibit the growth and increase apoptosis (cell death) of breast cancer cells.

Aspirin may prevent skin cancer

Australian scientists say that common drugs such as aspirin may hold the key to reducing the risk of developing skin cancer.

Statin drug reverses learning and attention deficits in a mouse model of the genetic disorder Neurofibromatosis type I

This week, researchers report evidence that a statin drug already shown to be safe for use in humans has proven effective at correcting cell-cell communication and curing learning disfunction in a mouse model of Neurofibromatosis type I, a human genetic disorder that causes learning disabilities in millions of people worldwide.

Chlamydia pneumoniae may cause vision problems

Researchers at the Massachusetts Eye and Ear Infirmary (MEEI) have found that Chlamydia pneumoniae, a bacterium linked to heart disease and capable of causing chronic inflammation, was present in the diseased eye tissue of five out of nine people with neovascular, or "wet," age-related macular degeneration (AMD).

Cell fusion triggered by viruses is a possible contributing factor in the development of human cancer

In some cases, the fusion of human cells is a normal process that leads, for instance, to the formation of muscle and bone. Viral infections can also cause cell fusion, but cells fused by viruses are widely considered to be harmless because they are generally believed to die without consequences for the host.
