Researchers identify molecular and protein signatures that predict HCV virus-induced liver injury

Researchers have discovered molecular and protein signatures that predict rapid onset of liver damage in hepatitis C patients following a liver transplant. The markers appeared soon after transplant and well before clinical evidence of liver damage.

Researchers use small molecule compound to generate reversible birth control in male mice

The development of a male contraceptive pill has long proven to be elusive, but findings from a new study may point scientists in the right direction to making oral birth control for men a reality.

Study reveals why human brain is large and more complex than that of other animals

Researchers have found what they believe is the key to understanding why the human brain is larger and more complex than that of other animals.

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.

T. gondii can cause inflammation in the brain

A parasite thought to be harmless and found in many people may actually be causing subtle changes in the brain, leading to suicide attempts.

PKS-positive E. coli may encourage development of colon cancer

Scientists at the University of Liverpool have identified a type of E. coli bacteria that may encourage the development of colon cancer.

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.

People with no dementia symptoms and high protein levels more likely to avoid the disease

People who are free of dementia and have high levels of a protein that indicates the presence of inflammation have relatives who are more likely to avoid the disease as well, according to a new study published in the August 15, 2012, online issue of Neurology, the medical journal of the American Academy of Neurology.

Biomedical engineer devises new noise model that is closer to the biological reality

Biomedical engineer Muhammet Uzuntarla from Bulent Ecevit University, Turkey, and his colleagues present a biologically accurate model of the underlying noise which is present in the nervous system.

Study looks at differences in brain structure between karate practitioners

Brain scans have revealed distinctive features in the brain structure of karate experts, which could be linked to their ability to punch powerfully from close range. Researchers from Imperial College London and UCL (University College London) found that differences in the structure of white matter - the connections between brain regions - were correlated with how black belts and novices performed in a test of punching ability.

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.

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.

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.

Low adropin levels may increase risk of metabolic disease

Working with a national team of researchers, a scientist from the Florida campus of The Scripps Research Institute has shown for the first time a link between low levels of a specific hormone and increased risk of metabolic disease in humans.

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.

Article describes novel technique to study interactions between HIV-1 and P. falciparum

The World Health Organization estimates that in 2011 there were 216 million cases of malaria and 34.2 million people living with HIV. These diseases particularly afflict sub-Saharan Africa, where large incidence of co-infection result in high mortality rates. Yet, in spite of this global pandemic, interactions between the parasite that causes malaria, Plasmodium falciparum, and HIV-1 are poorly understood.
