Low-radiocarbon nutrition permanently reduces genetic damage to brain cells

A new method of child and maternal nutrition could prevent a specific type of genetic damage that would otherwise occur in up to 160 million brain cells in each person over their lifetime. Preventing this genetic damage could have significant implications related to aging and cancer.

Removal of ZIP proteins from hippocampus cell protects them from injury

Researchers in the Blue Bird Circle Developmental Neurogenetics Laboratory in the department of neurology at Baylor College of Medicine have discovered that zinc enters cells through specialized protein gates known as ZIP transporters, and removing these ZIP proteins from cells in the hippocampus significantly protects them from injury.

Study: Stem cells play an unexpected role in male pattern balding

Given the amount of angst over male pattern balding, surprisingly little is known about its cause at the cellular level. In a new study, published in the Journal of Clinical Investigation, a team led by George Cotsarelis, MD, chair of the Department of Dermatology at the University of Pennsylvania School of Medicine, has found that stem cells play an unexpected role in explaining what happens in bald scalp.

Dutch scientists provide new insights into intestinal cancer through plant study

Dutch scientists have gained important new insights into intestinal cancer from studying a plant. The disease is called Peutz-Jeghers Syndrome, a hereditary disorder where people develop intestinal polyps that turn into malignant tumors.

TRPM2 in pancreatic beta-cells may control insulin secretion levels

The research group led by professor Makoto Tominaga and Dr. Kunitoshi Uchida, National institute for Physiological Sciences, found TRPM2 ion channel in pancreatic beta-cells is important for insulin secretion stimulated by glucose and gastrointestinal hormone secreted after food intake. Their finding was reported in Diabetes.

New research finds pattern for detecting 'false-positive' ANA results

The presence of antinuclear antibodies (ANA) indicates the possibility of autoimmunity and the indirect immunofluorescence (IIF) assay on HEp-2 cells is the standard blood test (ANA-HEp-2) used to detect ANA. However, studies have shown that a "false-positive" ANA test occurs in up to 13% of healthy individuals. In such cases the test detects the presence of autoantibodies that apparently are not associated with autoimmunity.

People fail to understand consequences of social trauma felt by bullied victims

Taunted, harassed, and pushed to a deadly breaking point. Last year, stories of teen bullying brought to life the heartbreaking consequences of young lives cut short by ruthless and unchecked behavior. While recent media coverage of these violent acts has increased national awareness of bullying's deadly consequences, it has done little to stop it from happening.

ddn conducts interview with lead plaintiff related to embryonic stem cell research case

Drug Discovery News, a news organization covering issues, trends and product news in the pharmaceutical drug development and discovery industry, recently conducted exclusive interviews with the lead plaintiffs in the controversial Sherley v. Sebelius lawsuit challenging President Barack Obama's order granting funding for embryonic stem cell research.

Low-fat lupin proteins

In emerging countries such as China or Brazil, meat consumption is rising dramatically. Indeed, worldwide consumption of red meat has quadrupled since 1961. The United Nations Food and Agriculture Organization (FAO) expects increasing prosperity to lead to a doubling of global meat production by the year 2050. The question is whether our planet, with its limited farmland resources, will still be able to meet all of our needs into the future.

Fundamental similarities in response to wasp infection and blood cancer development

Tiny parasitoid wasps can play an important role in controlling the populations of other insect species by laying their eggs inside the larvae of these species. A newly hatched wasp gradually eats the host alive and takes over its body.

Cold Spring Harbor Protocols features organ culture methods and transcriptome analysis

New technologies and methods are spurring a renaissance in the study of organogenesis. Organogenesis, essentially the process through which a group of cells becomes a functioning organ, has important connections to biological processes at the cellular and developmental levels, and its study offers great potential for medical treatments through tissue engineering approaches.

New options in fertility preservation for oncology patients

Many young people who've just learned that they have cancer also are told that the therapies that may save their lives could rob them of their ability ever to have children. Infertility caused by chemotherapy and radiation affects a sizable population: Of the 1.5 million people diagnosed with cancer in 2009, nearly 10 percent were still in their reproductive years.
