Walnuts provide key nutrients that may be essential in male reproductive health

Research published in the recent issue of Biology of Reproduction Papers-in-Press reports that 75 grams (approximately 2.5 ounces) of walnuts consumed per day improved sperm vitality, motility, and morphology (normal forms) in a group of healthy young men between 21-35 years of age.

Plexin B2-CD100 interaction for prompt activation of γδ T cells and wound healing

Scientists at The Scripps Research Institute have made a breakthrough in understanding a class of cells that help wounds in skin and other epithelial tissues heal, uncovering a molecular mechanism that pushes the body into wound-repair mode.

Sophisticated brain scans can accurately predict age

It isn't uncommon for people to pass for ages much older or younger than their years, but researchers have now found that this feature doesn't apply to our brains. The findings reported online on August 16 in Current Biology, a Cell Press publication, show that sophisticated brain scans can be used to accurately predict age, give or take a year.

Rhomboid enzymes and malaria treatment: an interview with Sinisa Urban

Rhomboid enzymes live in the cell’s membrane where their job is to cut the anchors of proteins, which releases the target proteins from the membrane.

Study uncovers new pathway that can treat depression

Depression takes a substantial toll on brain health. Brain imaging and post-mortem studies provide evidence that the wealth of connections in the brain are reduced in individuals with depression, with the result of impaired functional connections between key brain centers involved in mood regulation. Glial cells are one of the cell types that appear to be particularly reduced when analyzing post-mortem brain tissue from people who had depression.

Acute stress modifies DNA methylation and activity of certain genes

Acute stress alters the methylation of the DNA and thus the activity of certain genes. This is reported by researchers at the Ruhr-Universität Bochum together with colleagues from Basel, Trier and London for the first time in the journal Translational Psychiatry. "The results provide evidence how stress could be related to a higher risk of mental or physical illness", says Prof. Dr. Gunther Meinlschmidt from the Clinic of Psychosomatic Medicine and Psychotherapy at the LWL University Hospital of the RUB.

Researchers discover mechanisms responsible for chemoresistance in ovarian cancer

The presence of multiple ovarian cancer genomes in an individual patient and the absence or downregulation of the gene LRP1B are associated with the development of chemoresistance in women with the high-grade serous cancer subtype of ovarian cancer whose disease recurs after primary treatment. These study results are published in Cancer Research, a journal of the American Association for Cancer Research.

Radiosensitivity molecular signature can lead to better radiation therapy decisions for breast cancer

Researchers at Moffitt Cancer Center, working with colleagues in Sweden, the Netherlands and Puerto Rico, have validated a radiosensitivity molecular signature that can lead to better radiation therapy decisions for treating patients with breast cancer.

Combination of Zelboraf and immunotherapy increases tumor responses and survival in MM

Combining the recently approved BRAF inhibitor, Zelboraf with an engineered T cell immunotherapy to treat metastatic melanoma significantly increased tumor responses and survival in an animal model, researchers at UCLA's Jonsson Comprehensive Cancer Center have shown.

Human milk oligosaccharides may reduce risk of mother-to-child HIV transmission

An international team of researchers has found that certain bioactive components found in human milk are associated with a reduced risk of HIV transmission from an HIV infected mother to her breast-fed infant. Their study will be published in the August 15 online edition of American Journal of Clinical Nutrition.

Passenger deletions that deactivate essential genes provide new opportunity to strike cancer

Genomic deletions promote cancer by carving up or eliminating tumor-suppressor genes, but now scientists report in the journal Nature that the collateral damage they inflict on neighboring genes exposes cancer cells to vulnerabilities and new avenues for attack.

Medicago, IDRI receive FDA approval to commence Phase 1 H5N1 vaccine trial

The Infectious Disease Research Institute (IDRI), a Seattle-based non-profit research organization that is a leading developer of adjuvants used in vaccines combating infectious disease, and Medicago Inc., a biopharmaceutical company focused on developing highly effective and competitive vaccines based on proprietary manufacturing technologies and Virus-Like Particles (VLPs), announce that they have been cleared by the U.S. Food and Drug Administration (FDA) to initiate a Phase 1 clinical trial for an H5N1 Avian Influenza VLP vaccine candidate.

Special device provides evidence of how bloodstream infections begin

New research may help explain why hundreds of thousands of Americans a year get sick - and tens of thousands die - after bacteria get into their blood. It also suggests why some of those bloodstream infections resist treatment with even the most powerful antibiotics.

RNA-delivering nanoparticles allow rapid screening of new drug targets in mice

By sequencing cancer-cell genomes, scientists have discovered vast numbers of genes that are mutated, deleted or copied in cancer cells. This treasure trove is a boon for researchers seeking new drug targets, but it is nearly impossible to test them all in a timely fashion.

Inhibiting over-production of Panx1 protein can treat melanoma

New research from Western University, Canada, has identified a potential new target for the treatment of melanoma, the deadliest of all skin cancers. Silvia Penuela and Dale Laird discovered a new channel-forming protein called Pannexin (Panx1) that is expressed in normal levels on the surface of healthy skin cells.

Researchers discover why people with sickle cell disease get milder cases of malaria

Researchers at Duke University Medical Center may finally have discovered why people with sickle cell disease get milder cases of malaria than individuals who have normal red blood cells.

Cedars-Sinai's ICT-107 doubles median survival of patients with malignant brain tumor

An experimental immune-based therapy more than doubled median survival of patients diagnosed with the most aggressive malignant brain tumor, Cedars-Sinai Medical Center researchers reported in Cancer Immunology, Immunotherapy, published online Aug. 3.

CYCLOPS genes may serve as targets for cancer therapies

The genomic tumult within tumor cells has provided scientists at Dana-Farber Cancer Institute and the Broad Institute of MIT and Harvard with clues to an entirely new class of genes that may serve as an Achilles' heel for many forms of cancer.

Combination of exercise and S-nitrosoglutathione improves recovery from stroke

In a study published in the current issue of Restorative Neurology and Neuroscience scientists report that a therapy combining exercise with the neurovascular protective agent S-nitrosoglutathione (GSNO) improved recovery from stroke in a rat model. GSNO is a compound found naturally in the body and it has no known side effects or toxicity.
