New insights into perception - sensory processing of visual and tactile motion use overlapping neural circuits

In the classic waterfall illusion, if you stare at the downward motion of a waterfall for some period of time, stationary objects - such as rocks - appear to drift upward.

Thymosin beta-4 protein prompts damaged heart cells to repair themselves after a heart attack

A protein that the heart produces during its early development reactivates the embryonic coronary developmental program and initiates migration of heart cells and blood vessel growth after a heart attack, researchers at UT Southwestern Medical Center have found.

In the ICU, use of benzodiazepines, other factors may predict severity of post-stay depression

Psychiatrists and critical care specialists at Johns Hopkins have begun to tease out what there is about a stay in an intensive care unit (ICU) that leads so many patients to report depression after they go home.

Gene fusion discovery may lead to improved prostate cancer test

A newly discovered gene fusion is highly expressed in a subset of prostate cancers, according to a study by researchers at Weill Cornell Medical College.

Research points to a new approach to treating type 1 diabetes

Scientists at Burnham Institute for Medical Research (Burnham) and the University of California San Diego (UC San Diego) School of Medicine have demonstrated in mice that transplanted pancreatic precursor cells are protected from the immune system when encapsulated in polytetrafluorethylene (PTFE).

Discovery of key decision-point at which cells with broken DNA repair themselves or die

When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis.

Researchers explain process by which cells 'hide' potentially dangerous DNA segments

The DNA in the 23 pairs of chromosomes in each of the billions of cells of the human body is so tightly packed that it would measure six feet in length if stretched end to end.

Scientists discover the secrets of NF-kappaB

A study published in Science examines a key player in conditions such as cancer, inflammatory bowel disease, rheumatoid arthritis and asthma and has shown that cells use a sophisticated communication system to coordinate responses to infection and maintain inflammation in the body.

Researchers reveal how immune cells can be harnessed to target melanoma

Researchers at the Babraham Institute and the University of Catanzaro "Magna Graecia", Italy, co-ordinating an international network of scientists and clinicians from Europe, the USA and Japan, have identified new mechanisms through which the immune system recognises and responds to tumours like melanomas.

For cancer cells, genetics alone is poor indicator for drug response

In certain respects, cells are less like machines and more like people.

Deficiency in vitamin D may exacerbate autoimmune disease

Deficiency in vitamin D has been widely regarded as contributing to autoimmune disease, but a review appearing in Autoimmunity Reviews explains that low levels of vitamin D in patients with autoimmune disease may be a result rather than a cause of disease and that supplementing with vitamin D may actually exacerbate autoimmune disease.

Test predicts who will develop end-stage renal disease

Measuring kidney function by assessing two different factors-glomerular filtration rate (GFR) and urinary albumin levels-helps determine which patients with chronic kidney disease (CKD) will develop end-stage renal disease (ESRD), according to a study appearing in the May 2009 issue of the Journal of the American Society Nephrology (JASN).

Discovery of gene that protects against leukemia

Researchers have identified a gene that controls the rapid production and differentiation of the stem cells that produce all blood cell types -- a discovery that could eventually open the door to more streamlined treatments for leukemia and other blood cancers, in which blood cells proliferate out of control.

Research could lead to new non-antibiotic drugs to counter hospital infections

Lack of an adequate amount of the mineral phosphate can turn a common bacterium into a killer, according to research to be published in the April 14, 2009, issue of the Proceedings of the National Academies of Science.

New research should ease constipation

If you hate prune juice and chalky fiber supplements, just sit down and relax.

Dopamine agonists trigger destructive behaviors

A new study conducted at Mayo Clinic reports that one in six patients receiving therapeutic doses of certain drugs for Parkinson's disease develops new-onset, potentially destructive behaviors, notably compulsive gambling or hypersexuality.

New common pathway in neurodegenerative disease is a possible door to a point of no return

A just-out study suggests that what keeps chronic nervous system diseases such as Alzheimer's, Huntington's and ALS going - until they overcome the internal protective mechanisms a body can throw at them - may largely come down to poor conversational skills.

Many skin cancer patients do not receive sentinel lymph node biopsy

Although clinical practice guidelines recommend sentinel lymph node (SLN) biopsy for many patients with clinically node-negative melanoma, a new analysis from the National Cancer Database (NCDB) of the American College of Surgeons (ACS) has found approximately half of patients do not receive recommended evaluation of their lymph nodes and that the type of health insurance a patient has, the type of hospital delivering treatment, and the hospital's geographic region are all associated with provider compliance with those guidelines.

Research finds active brown fat in adult humans

Researchers at the Joslin Diabetes Center have demonstrated that adult humans still have a type of "good" fat previously believed to be present only in babies and children.
