Illegal drug usage in older people reduces quality of life: Research

Health and social services are facing a new challenge, as many illicit drug users get older and face chronic health problems and a reduced quality of life. That is one of the key findings of research published in the September issue of the Journal of Advanced Nursing.

Scientists discover over-expression of C35 gene in HER2 positive tumours

UK scientists have discovered that a gene called C35 can work together with other cancer-promoting genes to drive the growth and invasion of breast cancer cells in the lab.

Scientists discover molecular gatekeeper for arthritis

Elimination of a molecular gatekeeper leads to the development of arthritis in mice, scientists report in a study published in the Journal of Experimental Medicine. The newly discovered gatekeeper is a protein that determines the fate survival or death of damaging cells that mistakenly attack the body's own tissues and lead to autoimmune disorders such as arthritis.

Scientists suggest aggressive forms of breast cancer develops from intermediary cells

A UK research team has taken an important step forward in improving our understanding of the origins of breast cancer. Scientists at the Breakthrough Breast Cancer Research Centre at The Institute of Cancer Research (ICR) in London have found evidence suggesting that aggressive forms of breast cancer are likely to develop from intermediary slightly more developed cells, rather than from stem cells.

Consumption of medications for treatment of insomnia or anxiety increases mortality risk

Taking medications to treat insomnia and anxiety increases mortality risk by 36%, according to a study conducted by Genevi-ve Belleville, a professor at Universit- Laval's School of Psychology. The details of this study are published in the latest edition of the Canadian Journal of Psychiatry.

Researchers unveil protection mechanism of telomeres from DNA repair

In the latest issue of the journal Nature, Miguel Godinho Ferreira, Principal Investigator at the Instituto Gulbenkian de Ciência (IGC) in Portugal, lead a team of researchers to shed light on a paradox that has puzzled biologists since the discovery of telomeres, the protective tips of chromosomes: while broken chromosome ends generated by DNA damage (such as radiation or cigarette smoke) are quickly joined together, telomeres are never tied to each other, thus allowing for the correct segregation of the genetic material into all cells in our body.

Study finds long-term use of bone-strengthening drugs increase risk of oesophageal cancer

People who take bone-strengthening pills called bisphosphonates over a long period of time could be more likely to develop cancer of the oesophagus (gullet), new research suggests.

Researchers reveal surface protein alteration mechanism of mycoplasma bacteria

Pathogenic bacteria have evolved a variety of mechanisms to avoid being killed by the immune systems of the humans and animals they invade. Among the most sophisticated is that practised by mycoplasmas, which regularly change their surface proteins to confuse the immune system. Recent work in the group of Renate Rosengarten and Rohini Chopra-Dewasthaly at the University of Veterinary Medicine, Vienna has revealed surprising new details of the way they do so and at the same time raised important evolutionary questions.

Micro-RNAs programmed cells can lead to malignant growth

Cancer becomes life threatening when tumor cells start leaving their primary site. They travel through the lymph and blood streams to other tissues where they grow into metastases. This transition to malignancy is associated with characteristic changes in the cancer cells. The activity of several genes is reprogrammed and, thus, the production of proteins anchoring cells to a tissue is reduced. On the other hand, the amount of surface markers which make a cancer cell mobile increases.

Researchers discover low levels of DHA associated with chronic neurodegenerative disease

UC Irvine researchers have discovered that markedly depleted amounts of an omega-3 fatty acid in brain tissue samples from Alzheimer's patients may be due to the liver's inability to produce the complex fat, also contained in fish-oil supplements.Low levels of docosahexaenoic acid, or DHA, have been associated with the chronic neurodegenerative disease affecting millions of Americans, but no cause had been identified.

Scientists discover natural mechanism to discard amyloid protein

Chemists at the University of California, San Diego, have identified how a protein that accumulates in the brains of people with Alzheimer's disease interferes with the ability of cells to get rid of debris. They also found a natural mechanism by which this protein, amyloid beta, itself may be discarded.

Federal judge refuses to lift order blocking federal funding for stem cell research

The Associated Press: "A federal judge on Tuesday refused to lift his order blocking federal funding for some stem cell research, saying that a 'parade of horribles' predicted by federal officials would not happen. Medical researchers value stem cells because they are master cells that can turn into any tissue of the body.

Irregular body weight increases mortality risk in women with colon cancer: Study

Postmenopausal women diagnosed with colon cancer may be at increased risk of death if they fail to maintain a healthy body weight before cancer diagnosis, according to a study published in the September issue of Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Researchers synthesize new compounds to reduce A-beta 42 peptide in Alzheimer's disease

A team of scientists, led by University of California, San Diego School of Medicine researchers, has synthesized hundreds of new compounds with the potential of reducing the production of the A-beta 42 peptide, a primary component of Alzheimer's disease (AD).

Ohio State University receives five-year grant to improve drug therapy using gene profiles

The National Institute of General Medical Sciences has awarded a $9.1 million, five-year grant to The Ohio State University for a study titled "Expression Genetics in Drug Therapy." The goal of the research is to enhance drug response rates and reduce the number of adverse drug reactions among patients taking medication.

Neck manipulation may be risky without significant benefits: Study

According to new research manipulation for neck pain may carry a risk of serious injury, including stroke. For the study more than 120 patients with neck pain were included. They were randomly assigned to be treated with either manipulation or mobilization - which involves small, rhythmic movements applied to stiff or inflamed tissue. The outcome of both groups was almost identical, prompting researchers to conclude that manipulation may not be worth the risk.

People in low-income areas experience more penetrating injuries than those in high-income regions: Study

Penetrating injury rates were more than 20 times higher for persons living in the lowest income neighborhoods compared with those living in the highest income neighborhoods, according to a new study published in the August issue of the Journal of the American College of Surgeons. Researchers also found that those in the lowest-income neighborhoods experienced nearly six times higher rates of blunt injury than persons in the highest income neighborhoods. Penetrating injuries included those from firearms or cuts; blunt injuries included motor vehicle crashes, falls and assaults.
