Investigators describe process by which apoE4 protein promotes development of Alzheimer's

Despite researchers' best efforts, no drug exists that can slow, halt or reverse the onslaught of Alzheimer's disease. A progressive and fatal neurodegenerative disorder, Alzheimer's has stolen the memories and livelihoods of millions-leaving patients and their families struggling to cope with the disease's devastating consequences. But today, scientists at the Gladstone Institutes propose a new research avenue that has the potential to change all that.

Researchers examine impact of exercise on mare reproductive health and embryo transfer

In the latest issue of the Journal of Animal Science, researchers at Clemson University and the University of Florida examine the impact of exercise on mare reproductive health and embryo transfer.

Dendritic spines respond to and process synaptic inputs both chemically and electrically

It's the least understood organ in the human body: the brain, a massive network of electrically excitable neurons, all communicating with one another via receptors on their tree-like dendrites. Somehow these cells work together to enable great feats of human learning and memory. But how?

Scientists evaluate two different strategies to treat Usher syndrome

After years of basic research, scientists at Johannes Gutenberg University Mainz (JGU) are increasingly able to understand the mechanisms underlying the human Usher syndrome and are coming ever closer to finding a successful treatment approach. The scientists in the Usher research group of Professor Dr. Uwe Wolfrum are evaluating two different strategies. These involve either the repair of mutated genes or the deactivation of the genetic defects using agents.

ASU scientists use X-ray laser to reveal 3-D structure of cathepsin B enzyme

An international team of scientists, using the world's most powerful X-ray laser, has revealed the three dimensional structure of a key enzyme that enables the single-celled parasite that causes African trypanosomiasis (or sleeping sickness) in humans.

Scientists develop MitoFish for in vivo studies of mitochondria transport in nerve cells

Scientists have demonstrated a new way to investigate mechanisms at work in Alzheimer's and other neurodegenerative diseases, which also could prove useful in the search for effective drugs. For new insights, they turned to the zebrafish, which is transparent in the early stages of its life. The researchers developed a transgenic variety, the "MitoFish," that enables them to see - within individual neurons of living animals - how brain diseases disturb the transport of mitochondria, the power plants of the cell.

TSRI scientist to better define how brain organizes different types of memories among neurons

A scientist from the Florida campus of The Scripps Research Institute (TSRI) has been awarded approximately $2.5 million from the National Institute of Neurological Disorders and Stroke to better define how the brain organizes different types of memories among its neurons.

TAU scientists win top prize in American Society of Human Genetics art competition

The fine arts and the exact sciences may appear an unlikely pair, but creativity is a crucial element in both. Prof. Karen Avraham and PhD candidate Shaked Shivatzki of Tel Aviv University's Sackler Faculty of Medicine embraced this truth when creating Hearing and Deafness: Structure and Sequence, their winning submission to the recent American Society of Human Genetics art competition.

Western University research could lead to better treatments for PTSD and drug addiction

New research from Western University could lead to better treatments for Post-Traumatic Stress Disorder (PTSD) and drug addiction by effectively blocking memories. The research performed by Nicole Lauzon, a PhD candidate in the laboratory of Steven Laviolette at Western's Schulich School of Medicine & Dentistry has revealed a common mechanism in a region of the brain called the pre-limbic cortex, can control the recall of memories linked to both aversive, traumatic experiences associated with PTSD and rewarding memories linked to drug addiction.

Rice bran offers promising cancer prevention properties

A recent University of Colorado Cancer Center review in the journal Advances in Nutrition shows that rice bran offers promising cancer prevention properties. Meanwhile, an ongoing clinical trial is testing the effectiveness of rice bran in preventing the recurrence of colon cancer.

New prenatal genetic test results in more clinically relevant information

A large, multi-center clinical trial led by researchers from Columbia University Medical Center (CUMC) shows that a new genetic test resulted in significantly more clinically relevant information than the current standard method of prenatal testing.

Tyk2 enzyme helps regulate obesity through differentiation of brown adipose tissue

Approximately 68 percent of U.S. adults are overweight or obese, according to the National Cancer Institute, which puts them at greater risk for developing cancer, cardiovascular disease, diabetes and a host of other chronic illnesses. But an international team of scientists led by Virginia Commonwealth University Massey Cancer Center researcher Andrew Larner, M.D., Ph.D., has successfully reversed obesity in mice by manipulating the production of an enzyme known as tyrosine-protein kinase-2 (Tyk2).

Surprising discovery about physical properties of cancer cells

A surprising discovery about the physical properties of cancer cells could help improve a new diagnostic approach - a liquid biopsy - that detects, measures, and evaluates cancer cells in blood.

New metabolic biomarkers can detect risk of illnesses in advance

One of the big challenges of biomedicine is understanding the origin of illnesses in order to improve early detection and significantly increase recovery rates, as well as being able to do what CNIO researchers call preventive molecular medicine, which consists of identifying those individuals who have a greater molecular risk of suffering certain pathologies in order to prevent them.

Children with HIV more likely to develop atherosclerosis

Children with HIV have a 2.5 fold increased risk of atherosclerosis, according to research presented at EUROECHO and other Imaging Modalities 2012. Antiretroviral treatment, lipid lowering drugs and prevention with healthy lifestyles are needed to prevent early death from cardiovascular disease.

Copper can prevent horizontal transmission of genes in antibiotic-resistant bacteria

New research from the University of Southampton has shown that copper can prevent horizontal transmission of genes, which has contributed to the increasing number of antibiotic-resistant infections worldwide.

New method can generate stable human mesenchymal stem cells for bone engineering

Human mesenchymal stem cells (hMSCs) can develop into bone cells and are useful for tissue engineering and regeneration. However, when grown in the laboratory they quickly lose their ability to continue dividing and they die.

Inserm prizes for medical research to be awarded on Dec. 3

The 2012 Inserm prizes for medical research will be awarded at a ceremony at the Coll-ge de France on Monday 3 December 2012. This year, the grand prize will be awarded to Philippe Sansonetti in the presence of Marisol Touraine, France's Minister of Social Affairs and Health, Genevi-ve Fioraso, France's Minister of Higher Education and Research, and Professor Andr- Syrota, Chairman and CEO of Inserm.

Paper reveals how 'kinase' is distributed across membranes

Using a super-resolution fluorescent microscope, Australian medical scientists are a step closer to understanding why and how human immune cells decide to activate or not, thus enabling or preventing disease taking hold in the body.

Patient-centered relationship increases pain tolerance: Study

A doctor-patient relationship built on trust and empathy doesn't just put patients at ease - it actually changes the brain's response to stress and increases pain tolerance, according to new findings from a Michigan State University research team.
