A reliable way to replicate α-synuclein aggregation on cell membranes in Parkinson's disease patients

The accumulation of α-synuclein, a small, negatively charged protein, in neural cells, is one of the hallmarks of Parkinson's disease. It has been suggested that oligomeric α-synuclein causes membranes to become permeable, or to form channels on the outer cell membrane.

SSRIs increase risk of falling in nursing home residents with dementia

Nursing home residents with dementia who use average doses of selective serotonin reuptake inhibitors (SSRIs) are three times more likely to have an injurious fall than similar people who don't use these drugs. The association can be seen in people who use low doses of SSRIs and the risk increases as people take higher doses. The results are published in the British Journal of Clinical Pharmacology.

Research on neuron interaction could lead to potential treatment for addiction

Harvard scientists have developed the fullest picture yet of how neurons in the brain interact to reinforce behaviors ranging from learning to drug use, a finding that might open the door to possible breakthroughs in the treatment of addiction.

Insufficient sleep increases risk of becoming overweight

New research from Uppsala University, Sweden, shows that a specific brain region that contributes to a person's appetite sensation is more activated in response to food images after one night of sleep loss than after one night of normal sleep. Poor sleep habits can therefore affect people's risk of becoming overweight in the long run. The findings are published in the Journal of Clinical Endocrinology & Metabolism.

NIEHS study: 32M people in the U.S. have autoantibodies

A recent study conducted by the National Institute of Environmental Health Sciences (NIEHS), an agency of the National Institutes of Health (NIH), shows that 32 million people in the United States have autoantibodies, the most common of which are antinuclear antibodies.

HOXB13 gene mutation linked to familial prostate cancer risk

The quest for genetic information in the fight against prostate cancer is nearly two decades long. While researchers and doctors have long accepted the hereditary nature of the disease, in that closer relatives are at a two-fold increased risk of developing prostate cancer, the genetic explanation remained a mystery. Last week geneticists shared news of a novel gene mutation linked to familial prostate cancer risk.

New colorectal cancer screening test is highly accurate and more sensitive: Study

Results of two studies suggest that a new, investigational colorectal cancer screening test developed in a collaboration between Mayo Clinic and Exact Sciences Inc. of Madison, Wis., is highly accurate and significantly more sensitive than other noninvasive tests at detecting precancerous tumors (adenomas) and early-stage cancer.

Exposure to metformin may decrease risk of cancer

In 2005, news first broke that researchers in Scotland found unexpectedly low rates of cancer among diabetics taking metformin, a drug commonly prescribed to patients with Type II diabetes. Many follow-up studies reported similar findings, some suggesting as much as a 50-per-cent reduction in risk.

Study identifies mechanism that AML cells use to evade chemotherapy

A study published this week in the journal Leukemia identifies a mechanism that acute myeloid leukemia (AML) cells use to evade chemotherapy - and details how to close this escape route.

PfSET10 molecule plays a crucial role in malaria infection

The discovery by researchers from the Walter and Eliza Hall Institute of a molecule that is key to malaria's 'invisibility cloak' will help to better understand how the parasite causes disease and escapes from the defenses mounted by the immune system.

New genetic signature could cause bile duct cancer

Investigators at the Massachusetts General Hospital (MGH) Cancer Center have identified a new genetic signature associated with bile duct cancer, a usually deadly tumor for which effective treatment currently is limited.

Novel technique accurately maps gene-regulation proteins

A novel technique has been developed and demonstrated at Penn State University to map the proteins that read and regulate chromosomes -- the string-like structures inside cells that carry genes.

Scientists crack genetic code for Schistosoma haematobium

Scientists have cracked the genetic code and predicted some high priority drug targets for the blood parasite Schistosoma haematobium, which is linked to bladder cancer and HIV/ AIDS and causes the insidious urogenital disease schistosomiasis haematobia in more than 112 million people in Africa.

Dogs with spinal cord injuries may soon benefit from experimental drug

Dogs with spinal cord injuries may soon benefit from an experimental drug being tested by researchers at the University of California, San Francisco (UCSF) and Texas A&M College of Veterinary Medicine & Biomedical Sciences — work that they hope will one day help people with similar injuries.

TB associated with EGFR mutations in patients with lung adenocarcinoma

Tuberculosis (TB) has been suspected to increase a person's risk of lung cancer because the pulmonary inflammation and fibrosis can induce genetic damage. However, direct evidence of specific genetic changes and the disease have not been extensively reported.

Alpha-hemolysin may play an unexpected role in UTIs

Researchers from the University of Utah have identified a process by which the most common types of urinary tract infection-causing bacteria are able to trigger bladder cell shedding and disable immune responses. According to this new study, published in the Jan. 19, 2012, issue of Cell Host & Microbe, α-hemolysin, a toxin secreted by many strains of Escherichia coli (E. coli), may play an important, unexpected role during both the establishment and persistence of urinary tract infections.
