Researchers discover mechanism by which lead alters nerve cells in the brain

Exposure to lead wreaks havoc in the brain, with consequences that include lower IQ and reduced potential for learning. But the precise mechanism by which lead alters nerve cells in the brain has largely remained unknown.

Researchers observe how cholera decimates competing bacteria and human cells

Bacteria live in a state of perpetual warfare, with different species battling for dominion over their competitors and when pathogen, over their infected host. New research suggests that the human pathogen Vibrio cholerae, which causes the disease cholera, kills off its microbial rivals by jabbing them with a spring-loaded poison dagger.

Brain mitochondria are dysfunctional in early-stage Alzheimer's

Mitochondria -- subunits inside cells that produce energy -- have long been thought to play a role in Alzheimer's disease. Now Mayo Clinic researchers using genetic mouse models have discovered that mitochondria in the brain are dysfunctional early in the disease.

First clinical assessment of how interferon fights infections in people

A drug once taken by people with HIV/AIDS but long ago shelved after newer, modern antiretroviral therapies became available has now shed light on how the human body uses its natural immunity to fight the virus—work that could help uncover new targets for drugs.

New NOSH-aspirin appears more effective against cancer

Scientists have combined two new "designer" forms of aspirin into a hybrid substance that appears more effective than either of its forebears in controlling the growth of several forms of cancer in laboratory tests. Their report on the new NOSH-aspirin, so named because it releases nitric oxide (NO) and hydrogen sulfide (H2S), appears in the journal ACS Medicinal Chemistry Letters.

Walnuts associated with better memory scores and cognitive function

Do you recall what you ate for breakfast today or dinner last night? According to new research, you may have a better chance of remembering if you include walnuts. Recent findings published in the Journal of Alzheimer's Disease report walnut consumption in a Mediterranean diet is associated with better memory scores and cognitive function.

Alzheimer's disease drugs may act like a bad electrician

Alzheimer's disease drugs now being tested in clinical trials may have potentially adverse side effects, according to new Northwestern Medicine research. A study with mice suggests the drugs could act like a bad electrician, causing neurons to be miswired and interfering with their ability to send messages to the brain.

Scientists discover that sperm do not function like olfactory cells

According to a 2003 study by German and American scientists, a component of the Lily of the Valley scent known as Bourgeonal alters the calcium balance of human sperm and attracts the sperm. The "Lily of the Valley phenomenon" - also the title of a book about smelling - was born as a result of this discovery that sperm act as swimming olfactory cells which follow a "scent trail" laid by the egg. However, a detailed explanation for the Lily of the Valley phenomenon remained illusive as neither Bourgeonal nor other scents could be identified in the female sex organ.

Tiny molecule might help protect pancreas from cancer

A tiny molecule might help protect the pancreas from deadly disease and cancer. Tackling a mysterious process: There is a feeling that neglected cancers need more research and Pancreatic cancer is one of the least studied. Today, the survival rate is 3% for five years. Professor Petersen, at the School of Biosciences at Cardiff University, hopes his team's research can change that.

WUSM to study children with weakened immune systems

Not all viruses make us sick. But which ones are friends and which ones are foes? Researchers at Washington University School of Medicine in St. Louis have received a five-year, $3.3 million grant to study children with weakened immune systems to identify the viruses that make children sick.

Cannabinoids may be a target for new strategies in cancer treatment

Cannabis-like substances that are produced by the body have both therapeutic and harmful properties, besides their well-known intoxicating effects, and the body's cannabinoid system may be a target for new strategies in cancer treatment.

Scientists find evidence of a ‘different’ flu virus in bats

They were surprised to find genetic fragments of a flu virus in bats. So far, scientists haven't been able to grow it, and it's not clear if — or how well — it spreads. Flu bugs are common in humans, birds and pigs and have even been seen in dogs, horses, seals and whales, among others. About five years ago, Russian virologists claimed finding flu in bats, but they never offered evidence.

Aurora-A protein blocks proper functioning of tumor-suppressor p73

A protein abundantly found in treatment-resistant cancers holds an important tumor-suppressor out of the cell nucleus, where it would normally detect DNA damage and force defective cells to kill themselves, a team of scientists reports in the current Cancer Cell.
