Fish oil may help kidney disease sufferers

Fish oil, it's been touted as an answer to Alzheimers, arthritis and even weight-loss but now a Queensland University of Technology researcher will test its health benefits in people with chronic kidney disease.

Dietitian Rachel Zabel, from QUT's Institute of Health and Biomedical Innovation in Brisbane, Australia, will investigate the effects of fish oil on patients with kidney disease undergoing dialysis.

Ms Zabel said daily doses of fish oil in the form of a tablet or liquid had been shown to decrease inflammation - a common problem in people with kidney disease.

RNA analysis can identify rejection in lung transplants

Recent data from the Lung Allograft Rejection Gene expression Observational (LARGO) study provides compelling evidence that profiling gene expression in peripheral blood can detect organ rejection in lung transplant patients.

Screening teen risk behaviors

Research shows that adolescents who engage in one form of risky behavior, like drug or alcohol use, are likely to engage in other risky behaviors like self-harm, or having unprotected sex, but often times these behaviors are not discussed during a medical or mental health exam. Now, a new study shows that a simple and brief screening measure called the adolescent risk inventory (ARI) can quickly identify the broad range of risk behaviors found among adolescents.

Cherries may help reduce heart disease risk factors

Increasing intake of antioxidant-rich cherries may help lower the risk of metabolic syndrome and cardiovascular disease, suggests a new study(1) presented today at the Experimental Biology annual meeting.

Researchers say the animal study is encouraging and will lead to further clinical studies in humans.

Chinese medicinal herb stops formation of cysts in lethal kidney disease

Triptolide is derived from a Chinese medicinal herb, named Lei Gong Teng, which has been used in traditional medicine to treat cancer, inflammation, and auto-immune diseases and, more recently, also has been tested in Phase I clinical trials as an anti-tumor agent.

'Exercise pill' tells cells to burn fat

By giving ordinary adult mice a drug - a synthetic designed to mimic fat - Salk Institute scientist Dr. Ronald M. Evans is now able to chemically switch on PPAR-d, the master regulator that controls the ability of cells to burn fat. Even when the mice are not active, turning on the chemical switch activates the same fat-burning process that occurs during exercise. The resulting shift in energy balance (calories in, calories burned) makes the mice resistant to weight gain on a high fat diet.

Reversing cancer cells to normal cells

Northwestern University scientist Mary J.C. Hendrix and colleagues discovered that aggressive melanoma cells (but not normal skin cells nor less aggressive melanoma cells) contain specific proteins similar to those found in embryonic stem cells. This groundbreaking work led to the first molecular classification of malignant melanoma and may help to explain how, by becoming more like unspecialized stem cells, the aggressive melanoma cell gained enhanced abilities to migrate, invade and metastasize while virtually undetected by the immune system.

Tart cherries may alter heart/diabetes factors

Tart cherries may be good for more than just making pie, according to new data from an animal study conducted by University of Michigan Health System researchers and presented today at a major scientific meeting.

Unicellular microRNA discovery

Dr. Yijun Qi (National Institute of Biological Sciences, China), reports his discovery of microRNAs in the unicellular green alga, Chlamydomonas reinhardtii. This is the first finding of microRNAs in a unicellular organism.

“The finding changes the dogma that miRNAs only exist in multicellular organisms, and adds an important piece into the blooming small RNA world. A pressing question we have now is what these miRNAs are exactly doing in the green alga. I hope we will know the answers soon,” says Dr. Qi.

Genes that turn a plant's ability to self-pollinate on and off

Some plants need a partner to reproduce. Pollen from one plant pollinates the stigma of another, and a seed is formed. But other plants can self-pollinate, a handy survival mechanism for a lonely plant.

Aspirin may be less effective heart treatment for women than men

A new study shows that aspirin therapy for coronary artery disease is four times more likely to be ineffective in women compared to men with the same medical history.

Historically, studies have shown that aspirin therapy is less effective in women than in men, but it has remained unclear how much less effective and whether this affects patient outcomes, said Michael Dorsch, clinical pharmacist and adjunct clinical instructor at the University of Michigan College of Pharmacy.

New study may explain why alcohol consumption increases breast cancer risk

For the first time, scientists have used a laboratory mouse model to mimic the development of human alcohol-induced breast cancer.

Alcohol (EtOH) consumption -- even moderate -- is a well-established risk factor for breast cancer in women. A recent study showed that 60 percent of female breast cancers worldwide were attributable to alcohol consumption. Nevertheless, the mechanisms of alcohol-induced breast cancer are poorly understood.

Decreasing ischemia and reperfusion in heart transplants

A new study, led by Felix Aigner, M.D., has identified a protein known as Lipocalin-2 (Lcn-2) as potentially responsible for regulating the body's inflammatory response during heart transplants.

Arming the fight against resistant bacteria

In 1928, Alexander Fleming opened the door to treating bacterial infections when he stumbled upon the first known antibiotic in a Penicillium mold growing in a discarded experiment.

Nanocomposites for more durable tooth fillings

The mouth is a tough environment, which is why dentists do not give lifetime guarantees. Despite their best efforts, a filling may eventually crack under the stress of biting, chewing and teeth grinding, or secondary decay may develop where the filling binds to the tooth. Fully 70 percent of all dental procedures involve replacements to existing repairs, at a cost of $5 billion per year in the United States alone.
