Genetic markers for testosterone and estrogen level regulation identified

A research study led by the Peninsula College of Medicine and Dentistry, University of Exeter, and Boston University School of Medicine, in collaboration with a global consortium, has identified genetic markers that influence a protein involved in regulating oestrogen and testosterone levels in the bloodstream.

BUSM researchers identify genetic markers for testosterone, estrogen level regulation

(Boston) – A research study led by Boston University School of Medicine (BUSM) and the University of Exeter in the United Kingdom, in collaboration with a global consortium, has identified genetic markers that influence a protein involved in regulating estrogen and testosterone levels in the bloodstream.

Stone Age tools help to streamline modern manufacturing

Innovative research published by the National Physical Laboratory (NPL) and the University of Bradford uses laser microscopes to explore how stone tools were used in prehistory, and the process has helped streamline surface measurement techniques for modern manufacturers.

Complications following 2-level axial lumbar interbody fusion

Charlottesville, VA (July 20, 2012). Surgeons from the Instituto de Patologia da Coluna in Sao Paulo, Brazil have found that an innovative minimally invasive surgical procedure performed to achieve two-level axial lumbar interbody fusion produced immediate successful results, but within 2 years complications set in, making the procedure far less desirable. Findings of this study are reported in the article "Results and complications after 2-level axial lumbar interbody fusion with a minimum 2-year follow-up.

Numbers of blind are falling

The numbers of people in Germany who are blind or visually impaired is going down. Robert P. Finger and his co-authors present their findings in the current edition of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2012; 109[27/28]: 484-9).

3-D tumor models improve drug discovery success rate

Imagine millions of cancer cells organized in thousands of small divots. Hit these cells with drugs and when some cells die, you have a candidate for a cancer drug. But a review published this week in the journal Expert Opinion on Drug Discovery argues that these 2D models in fact offer very little information about a potential drug's effects in the body and may often give researchers misleading results.

Stem cell research aids understanding of cancer

The study, published in the journal Stem Cell, adds to our understanding of the role of stem and next stage progenitor cells in tissue regeneration and in the diagnosis and treatment of cancer.

While stem cells are known to reside in organs such as the liver and pancreas, they are difficult to isolate. The new findings show that an antibody developed by the team can be used to capture the stem cells.

Beneficial bacteria may help ward off infection

While many bacteria exist as aggressive pathogens, causing diseases ranging from tuberculosis and cholera, to plague, diphtheria and toxic shock syndrome, others play a less malevolent role and some are critical for human health.

In a new study, Cheryl Nickerson and her group at ASU's Biodesign Institute, in collaboration with an international team* including Tom Van de Wiele and lead author Rosemarie De Weirdt at Ghent University, Belgium, explore the role of Lactobaccilus reuteri—a natural resident of the human gut—to protect against foodborne infection.

Meta-analysis: Interventions improve depression in cancer patients

Despite guidelines recommending screening for depression in cancer patients, it's been unclear whether interventions designed to treat this depression are effective. A study by the University of Colorado Cancer Center and other institutions, published in the Journal of the National Cancer Institute, changes that. This meta-analysis of 10 studies encompassing 1362 patients shows that especially cognitive behavioral therapy and pharmacologic interventions decrease depressive symptoms in cancer patients.

Inaugural cross-disciplinary Public Participation in Scientific Research conference

Though public participation in scientific research has deep roots in the history of science, in the last few years it has taken off spectacularly from launch pads across the disciplines of science and education, fueled by advances in communications technology and a sea change in a scientific culture now eager to welcome outsiders as collaborators.

DNDi and Cipla to develop 4-in-1 pediatric antiretroviral drug combination

On the eve of the XIX International AIDS Conference in Washington, DC, the Drugs for Neglected Diseases initiative (DNDi), a not-for-profit research and development (R&D) organization, announces a new collaboration with Indian drug manufacturer Cipla to develop and produce an improved first-line antiretroviral (ARV) combination therapy specifically adapted to meet the treatment needs of infants and toddlers living with HIV/AIDS.

Vitamin D may protect against lung function impairment and decline in smokers

Vitamin D deficiency is associated with worse lung function and more rapid decline in lung function over time in smokers, suggesting that vitamin D may have a protective effect against the effects of smoking on lung function, according to a new study from researchers in Boston.

Rutgers study: Anxiety disorders in poor moms likely to result from poverty, not mental illness

NEW BRUNSWICK, N.J. – Poor mothers are more likely to be classified as having the mental illness known as generalized anxiety disorder (GAD) because they live in poverty – not because they are suffering from a psychiatric disorder, according to Rutgers researchers.

Lack of insurance linked to advanced stage cervical cancer

ATLANTA –July 19, 2012—A large national sample of women diagnosed with cervical cancer between 2000 and 2007 finds lack of insurance was second only to age as the strongest predictor of late stage at diagnosis, a gap the authors say is likely attributable to lack of screening.

Novel anti-malarial drug target identified

An international team of scientists, led by researchers from the Department of Pediatrics at the University of California, San Diego School of Medicine, have identified the first reported inhibitors of a key enzyme involved in survival of the parasite responsible for malaria. Their findings, which may provide the basis for anti-malarial drug development, are currently published in the online version of the Journal of Medicinal Chemistry.
