Studies to identify molecular causes and preventive and therapeutic strategies for Parkinson's

On the fourth floor of Wichita State University's McKinley Hall, biochemistry professor Kandatege Wimalasena and his group of doctoral and undergraduate students are hard at work researching Parkinson's disease (PD) - the second-most common neurodegenerative disease, affecting 1 to 2 percent of people older than 60.

Scientists trace nanoparticles taken up from soils by crop plants

Scientists have, for the first time, traced the nanoparticles taken up from the soil by crop plants and analysed the chemical states of their metallic elements. Zinc was shown to dissolve and accumulate throughout the plants, whereas the element cerium did not dissolve into plant tissue.

Researchers identify an exceptional mouse model of schizophrenia

Researchers at the Institute for Comprehensive Medical Science, Fujita Health University and the National Institute for Physiological Sciences, Japan, along with colleagues from 9 other institutions, have identified an exceptional mouse model of schizophrenia.

Key details of how TRF2 protein performs crucial chromosome-protecting function

We take it for granted that our chromosomes won't stick together, yet this kind of cellular disaster would happen constantly were it not for a protein called TRF2. Now, scientists at The Scripps Research Institute (TSRI) have discovered key details of how TRF2 performs this crucial chromosome-protecting function.

Drug-carrying nanoparticles have another hurdle to overcome - escaping the bloodstream

Many medically minded researchers are in hot pursuit of designs that will allow drug-carrying nanoparticles to navigate tissues and the interiors of cells, but University of Michigan engineers have discovered that these particles have another hurdle to overcome: escaping the bloodstream.

Basis of antidepressant drugs and electroconvulsive therapy found

Through a series of investigations in mice and humans, Johns Hopkins researchers have identified a protein that appears to be the target of both antidepressant drugs and electroconvulsive therapy. Results of their experiments explain how these therapies likely work to relieve depression by stimulating stem cells in the brain to grow and mature.

Liver gene found to regulate cholesterol and fat blood levels

Researchers have identified a microRNA liver gene, miR-27b, which regulates lipid (cholesterol or fat) levels in the blood. This regulator gene controls multiple genes involved in dyslipidemia—abnormal blood cholesterol levels that can contribute to heart disease.

Migraine, epilepsy and genetics: an interview with Dr. Melodie Winawer

This work is the product of an extraordinary consortium called the Epilepsy Phenome/Genome project (EPGP). It is a consortium of 27 centres in the U.S. and internationally with several hundred physicians and staff who have worked together to enrol more than 4000 patients with epilepsy and their family members.

New method can determine seriousness of cancer prognosis with 80% certainty

The number of incorrect cancer prognoses can be halved with computerised image analysis. In three years time, the method can be used on patients with bowel cancer, ovarian cancer and prostate cancer.

More than £6M funding awarded to enhance development of biopharmaceuticals

More than £6M of funding has been awarded to enhance the development of biopharmaceuticals. In total £6.5M will fund 12 projects to deliver commercially important results, such as industrial-scale production of antibodies, stem cell preservation at room temperature, biopharmaceutical production using microbes and commercial scale stem cell therapy.

Boston College biologist to explore connection between peripheral neuropathy and HIV

Boston College biologist Tricia Burdo has been awarded a five-year, $1.9 million grant from the National Institutes of Health to study the role of the body's immune response in a debilitating form of nerve damage suffered by people living with HIV.

DHA more effective than EPA in preventing liver inflammation and fibrosis

Research at Oregon State University has found that one particular omega-3 fatty acid has a powerful effect in preventing liver inflammation and fibrosis - common problems that are steadily rising along with the number of Americans who are overweight.

RRM1 gene may better predict survival for pancreatic adenocarcinoma

Moffitt Cancer Center researchers have identified a gene that may better predict survival for pancreatic adenocarcinoma, the fourth leading cause of cancer deaths in the United States.

Researchers assess complete landscape of kinome expression in cancer

When it comes to gene sequencing and personalized medicine for cancer, spotting an aberrant kinase is a home run. The proteins are relatively easy to target with drugs and plenty of kinase inhibitors already exist.

Paternal obesity may alter genetic mechanisms in next generations

A father's obesity is one factor that may influence his children's health and potentially raise their risk for diseases like cancer, according to new research from Duke Medicine.

Non-O blood type - the most important risk factor for venous thromboembolism

The non-O ABO blood type is the most important risk factor for venous thromboembolism (blood clots in veins), making up 20% of attributable risk for the condition, according to a new study in CMAJ (Canadian Medical Association Journal).

GSTM gene mutation, air pollution can increase risk of asthma-related cockroach allergy

An allergic reaction to cockroaches is a major contributor to asthma in urban children, but new research suggests that the insects are just one part of a more complex story. Very early exposure to certain components of air pollution can increase the risk of developing a cockroach allergy by age 7 and children with a common mutation in a gene called GSTM may be especially vulnerable.

Study findings suggest physical and pharmacological solutions for human stroke victims

Johns Hopkins researchers have found that mice can recover from physically debilitating strokes that damage the primary motor cortex, the region of the brain that controls most movement in the body, if the rodents are quickly subjected to physical conditioning that rapidly "rewires" a different part of the brain to take over lost function.

Non-coding RNA MALAT1 influences lung cancer metastasis

The vast majority - approximately 80 percent - of our DNA does not code for proteins, yet it gets transcribed into RNA. These RNA molecules are called non-coding and fulfill multiple tasks in the cell. Alongside a well-studied group of small RNAs, there is also a class of so-called long non-coding RNAs consisting of more than 200 nucleotides.

Oleuropein aglycone reduces inflammation associated with intestinal ischemia and reperfusion

Here's another reason why you should include olive oil in your diet: A new research report published in the Journal of Leukocyte Biology suggests that at least one compound in olive oil significantly reduces intestinal ischemia (restricted blood supply) and the resulting reperfusion injury (tissue damage caused when blood supply returns).
