Researchers discover new gene in colon cancer
...Without 15-PGDH present,unchecked COX-2 goes on to cause
abnormal changes on the cellular level, which may lead to tumor development." Previous studies have shown that patients who take nonsteroidal anti-inflammatory drugs (NSAIDs), which are COX-2 inhibitors, have a lower incidence of colon cancer. COX-2 ...
Vitamin E in plant seeds could halt prostate, lung cancer, says Purdue scientist
... prior indications that some form of vitamin E may cause
cell death in some mouse cell lines, we are the first to provide a mechanism for such an effect." Gamma-tocopherol, though rarely available in vitamin pills, is nevertheless found in abundance in the typical American diet. Many nuts are rich...
UCSB makes important advances in studies of retinal detachment
...own stimuli, these cells begin to contract and can cause
the retina to tear or re-detach. In humans, PVR is the most common cause
of failure of retinal reattachment surgery. It occurs in five to 10 percent of all cases. Essent...
Alcohol vulnerability linked to action of insulin
...vity is inhibited, the amount of alcohol needed to cause
inebriation decreases. The scientists had also examined different regions of the fly brain to determine where the Protein Kinase had its effect. In the new research they zeroed in on a small group of neurons in the brain, specifically cells producing...
Gene vaccine for Alzheimer's disease shows promising results
...ems of mice to fight against amyloid proteins that cause
the devastating plaques that are characteristic of Alzheimer's disease. For years scientists have examined the possibility of using a protein-based vaccine to slow the progression of the disease in its early stages. UT Southwestern researchers have c...
Cigarette smoking exacerbates alcohol-induced brain damage
...nic, heavy alcohol consumption is already known to cause
brain damage. Cigarette smoking can also cause
brain damage, both in conjunction with alcohol use as well as independently. These findings have imp...
A genetic difference at the opiate receptor gene affects a person's response to alcohol
...intravenous doses of alcohol that were designed to cause
breath alcohol concentration (BAC) levels of .02, .04, and .06. Researchers measured subjective intoxication, stimulation, sedation, and mood states at baseline and at each of the three BAC levels. Results indicate that individuals with the G alle...

of deaths in industrialised countries. In experiments with a model of cerebral ischemia using rats, a team from the Institute of Neurosciences of the Universitat Autnoma de Barcelona (Spain) has observed how the presence of ranitidine reduces neurona...
New route to Parkinson's found in cells' 'garbage disposal' system
... mutations in a key gene called parkin are a major cause
of Parkinson's disease (PD). Now they have discovered a new mechanism by which the parkin gene can be compromised, a finding that they say could lead to new drugs for the disorder. Andrea Lozano, Senior Scientist at the Toronto Western Research Insti...
