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.

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.

CU professor to interview epilepsy sufferers and their families in depth

Sara Shostak, assistant professor in the department of sociology, along with principal investigator Ruth Ottman, professor of epidemiology at Columbia University, and other collaborators were recently awarded a $2 million grant from The National Institute of Neurological Disorders and Stroke (NINDS) to learn more about these questions.

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.

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.

Childhood adversity may lead to epigenetic changes in glucocorticoid receptor gene

In a look at how major stressors during childhood can change a person's biological risk for psychiatric disorders, researchers at Butler Hospital have discovered a genetic alteration at the root of the association.

New RNA interference method holds promise for cancer, other diseases

For the past decade, scientists have been pursuing cancer treatments based on RNA interference - a phenomenon that offers a way to shut off malfunctioning genes with short snippets of RNA. However, one huge challenge remains: finding a way to efficiently deliver the RNA.

Rare egg producing stem cells in women’s ovaries discovered

It was known till now that women were born with all the eggs they'll ever have. But now Harvard scientists have found that ovaries of young women harbor very rare stem cells capable of producing new eggs. The researchers feel that harnessing those stem cells might one day lead to better treatments for women left infertile because of disease or age.

MGH scientists isolate OSCs from ovaries of reproductive age women

For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

CML patients can benefit from imatinib after unsuccessful interferon therapies

A new study has found that patients with chronic myeloid leukemia (CML) who have not responded to interferon treatments experience long-term benefits when they switch to the targeted drug imatinib.

Survey: 49% of asthma patients are not using controllers

Forty-nine percent of children and adults with persistent asthma are not using controller medications according to results of a first of its kind survey of 1,000 asthma sufferers.

Researchers identify elusive gene responsible for TAR syndrome

Researchers have identified an elusive gene responsible for Thrombocytopenia with Absent Radii (TAR), a rare inherited blood and skeletal disorder. As a result, this research is now being transformed into a medical test that allows prenatal diagnosis and genetic counselling in affected families.

Skin cancer drug may prolong survival in advanced cases: Study

Researchers say 132 patients in the U.S. and Australia who were given the drug vemurafenib gained several extra months of life. The study published in the New England Journal of Medicine found that those on the drug lived an average of 16 months, compared with nine months on conventional treatment.

Seven scientists aim to make strides in predicting and preventing preterm birth

With the help of funding from the March of Dimes, researchers from five states and Canada are seeking answers to questions such as how cellular-level processes that control uterine muscles may affect preterm labor, the causes of preeclampsia, and how air pollution may affect pregnancy and preterm birth - all with the goal of preventing preterm birth so more babies will get a healthy start in life.

Evolutionary forces encourage diversity in the active surfaces of venomous toxins

For snakes, spiders, and other venomous creatures, the "business end," or active part, of a toxin is the area on the surface of a protein that is most likely to undergo rapid evolution in response to environmental constraints, say researchers from Ben Gurion University in Israel.

Study evaluates how environmental triggers might alter epigenetics of CFS

A University of Toronto Scarborough (UTSC) researcher is examining how environmental triggers might alter gene function in people with Chronic Fatigue Syndrome. The research could lead to better insights into the disease and eventually to new treatments.
