A team of researchers from China and the University of Oregon have developed an approach for neuroscientists to study how meditation might provide improvements in a person's attention and response to stress.

The study, done in China, randomly assigned college undergraduate students to 40-person experimental or control groups. The experimental group received five days of meditation training using a technique called the integrative body-mind training (IBMT). The control group got five days of relaxation training. Before and after training both groups took tests involving attention and reaction to mental stress.

A combination of drugs widely used to treat infections caused by HIV appears to stop brain damage caused by the virus as well, according to a new study.

The study involved 53 men and women with an average age of 38. The participants were given a combination of several antiretroviral drugs known as Highly Active Anti-Retroviral Therapy (HAART) for one year. Researchers tested the participants’ cerebrospinal fluid before and after treatment to see if there were elevated levels of a particular biomarker for brain injury called neurofilament light protein.

The study found 21 people had high levels of the protein, suggestive of brain damage, at the beginning of treatment.

Today's microdevices rely on external energy sources, severely limiting their mobility and autonomy in biofactory environments. New research by a group led by Dr. MinJun Kim at Drexel seeks to use a monolayer of harmless, genetically modified bacteria as a power source, which would allow future “nano-bots” to be both autonomous and self-contained.

When fabricating nanoscale motors and in developing micron-scale power sources, the actuating of fluids in microfluidic systems is usually achieved through the use of large external actuators. Dr. Kim's team is exploring the possibility of using microorganisms as a method for fabricating nanoscale elements.

A new survey(C) released by Litozin joint health reveals that men and women who aim to keep fit, could in fact, be damaging their joints. Over two thirds (68%) of all active respondents who took part in the survey had suffered from joint pain at some point.

Joint injuries seem to be a common occurrence for the nations top sports performers with David Beckham and Freddy Flintoff both recent victims.

Commissioned by LitoZin(R), a rosehip based supplement which improves joint health, the survey looked at the impact on joint health of various sporting activities amongst groups of men and women in the under 45 and over 45 age groups who all undertook 10 hours or more of light exercise a month.

Cancer patients receiving chemotherapy have not noticed a restriction in their access to treatment following the enactment of the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (MMA), despite the act's significant reduction in government reimbursement to oncologists, according to a new study led by researchers in the Duke Clinical Research Institute (DCRI).

“Critics of the MMA often said that it would reduce patients’ access to chemotherapy services, because doctors would receive 30 to 40 percent less reimbursement from the government for administering treatment,” said Kevin Schulman, M.D., director of the DCRI’s Center for Clinical and Genetic Economics, and senior investigator on the study.

Researchers in a multicenter international study state that if the HMMR gene becomes mutated it may increase a woman’s risk of breast cancer by more than a third.

Further, the researchers found that the gene interacts with the well-known breast cancer gene BRCA1. Alternations in either gene cause genetic instability and interfere with cell division, which could be a path to breast cancer developing. This leads researchers to not just a single gene, but a pathway that may be a potential target for treating or detecting breast cancer.

HMMR is mutated in about 10 percent of the population. Mutations in the two main genes involved in breast cancer susceptibility, BRCA1 and BRCA2, occur in about one of every 300 individuals, or less than 1 percent of the population.
