Walnuts and walnut oil reduce blood pressure during stress: Study

A diet rich in walnuts and walnut oil may prepare the body to deal better with stress, according to a team of Penn State researchers who looked at how these foods, which contain polyunsaturated fats, influence blood pressure at rest and under stress.

NIH awards Scripps Research grants to study the mechanisms of protein complex

For Immediate Release -Scripps Research Institute scientists have been awarded approximately $65 million in four five-year grants as part of the National Institutes of Health's (NIH) latest round of structural biology funding. The projects will focus on determining the shapes and functions of proteins and protein complexes that are important in biology and medicine.

Cell aging is associated with reduced histone level

Like cats, human cells have a finite number of lives-once they divide a certain number of times they change shape, slow their pace, and eventually stop dividing, a phenomenon called cellular senescence.

Study on immune system activation may help develop new drugs for infections

A new research report in the October 2010 print issue of the Journal of Leukocyte Biology sheds important light on how our immune systems detect invading organisms to be destroyed and removed from our bodies. The information from this research should ultimately help lead to the development of new drugs and treatments that allow health care providers to prevent runaway immune reactions that can have devastating consequences for people.

Researchers find STIM1 protein inhibits voltage-operated calcium channels

A calcium sensing protein, STIM1, known to activate store-operated calcium channels has been found to also inhibit voltage-operated calcium channels, according to researchers at Temple University.

Researchers discover new mechanism of DNA repair process

Tucked within its double-helix structure, DNA contains the chemical blueprint that guides all the processes that take place within the cell and are essential for life. Therefore, repairing damage and maintaining the integrity of its DNA is one of the cell's highest priorities.

Scientists identify a new way to cure food allergies

Johns Hopkins scientists have discovered a way to turn off the immune system's allergic reaction to certain food proteins in mice, a discovery that could have implications for the millions of people who suffer severe reactions to foods, such as peanuts and milk.

UCLA receives contract to study proteins involved in cardiovascular disease development

UCLA has received a five-year, $12.5 million contract award from the National Heart, Lung and Blood Institute to spearhead an international consortium of medical experts that will study proteins that may be involved in the development of cardiovascular disease.

Vitamin D deficiency in African-American women can increase risk of aggressive breast cancer: Study

African-American women had lower vitamin D levels than white women, and vitamin D deficiency was associated with a greater likelihood for aggressive breast cancer, according to data presented at the Third AACR Conference on the Science of Cancer Health Disparities.

Study shows low DRC level may increase risk for non-melanoma skin cancer

DNA repair capacity (DRC) measurements effectively identified individuals who were at high risk for non-melanoma skin cancer, and may be a useful method to evaluate the efficacy of preventive therapies, according to study results presented at the Third AACR Conference on the Science of Cancer Health Disparities.

Scientists find new replicating mechanism of Salmonella bacteria

New findings by National Institutes of Health scientists could explain how Salmonella bacteria, a common cause of food poisoning, efficiently spread in people. In a study published this week in the Proceedings of the National Academy of Sciences, researchers describe finding a reservoir of rapidly replicating Salmonella inside epithelial cells. These bacteria are primed to infect other cells and are pushed from the epithelial layer by a new mechanism that frees the Salmonella to infect other cells or be shed into the intestine.

Stem cell research breakthrough

Australian researchers have grown new human stem cells outside the body and this may provide new hope to cancer patients and those with genetic disorders. The team found a way to manipulate the environment of blood-forming stem cells to make them multiply.

Siblings of children with autism have language delays: Study

Siblings of children with autism have more frequent language delays and other subtle characteristics of the disorder than previously understood. Girls also may be mildly affected more often than recognized in the past.

Activating rearrangements in receptor genes are more common than previously thought

A multi-institutional team led by investigators from Memorial Sloan-Kettering Cancer Center has published a study that provides new insight into genetic changes that make some forms of glioblastoma, the most common type of primary brain cancer, more aggressive than others and explains why they may not respond to certain therapies. The research was led by senior author Eric C. Holland, MD, PhD,--an MSKCC surgeon, researcher and the Director of the Brain Tumor Center--and was published in the October 1 issue of the journal Genes & Development.

Increase in levels of P450 protein creates EET molecules that lower blood pressure

If you are one of the millions of Americans with high blood pressure, more help is on the way. That's because a new research study published in the October 2010 print issue of The FASEB Journal shows that a protein, called P450, metabolizes arachidonic acid in our blood vessel walls to create a tiny molecule with a big name-epoxyeicosatrienoic acid (EET)-which in mice, turns off genes responsible for vascular inflammation and ultimately relaxes blood vessels to lower blood pressure. This protein and genes are also present in humans.

Study suggests balance between NF-kB and p53 signaling as a promising target for new cancer drugs

A new report published in the October 2010 print issue of The FASEB Journal offers a ray of hope in the search for new cancer drugs. By examining the seemingly conflicting roles of how oncogenes and tumor suppressor genes handle cellular stress, scientists from the Institute for Advanced Studies in New Jersey argue that each of these opposing systems could be potent drug targets in the effort to stop cancer. In addition, their hypothesis provides new insights into what contributes to immunological disorders such as chronic inflammation and autoimmune diseases.

Lying creates desire to clean the 'dirty' body part: Study

Apparently your mom had it right when she threatened to wash your mouth out with soap if you talked dirty. Lying really does create a desire to clean the "dirty" body part, according to a University of Michigan study.

Report finds development of multiple myeloma is tied to 'hypomethylation'

DNA methylation - a modification of DNA linked to gene regulation - is altered with increasing severity in a blood cancer called multiple myeloma, according to a study by Mayo Clinic and the Translational Genomics Research Institute (TGen).
