Predictors for sickle-cell-anemia complications

Researchers at UT Southwestern Medical Center have determined that the level, or saturation, of oxygen in blood could be used to identify children with sickle cell anemia who are at an increased risk of stroke.

New insights into what happens on a molecular level during photosynthesis

In a technical advance that could allow researchers to watch cells as they act during the process of photosynthesis, scientists have developed a method that extends the power of fluorescence-mediated bio-imaging to see discrete pigments inside live cells of bacteria.

How much and how often people drink influences mortality risk

How much and how often people drink - not just the average amount of alcohol they consume over time - independently influence the risk of death from several causes, according to a new study by researchers at the National Institutes of Health (NIH).

Researchers discover molecular pathway in blood vessels that controls blood pressure and vascular function

University of Iowa researchers have identified a molecular pathway in blood vessels that controls blood pressure and vascular function and may help explain why certain drugs for type II diabetes also appear to lower patients' blood pressure.

PET/CT planning beneficial for head and neck cancer patients

Using a combination of positron emission tomography (PET) and computed tomography for radiation therapy treatment planning in head and neck carcinoma patients provides for excellent, local and regional disease control when compared to CT alone, according to a study in the March 1 issue of the International Journal for Radiation Oncology*Biology*Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.

ISG15 protein inhibits Ebola from reaching out to infect neighboring cells

Scientists at the University of Pennsylvania School of Veterinary Medicine have identified a protein, ISG15, that inhibits the Ebola virus from budding, the process by which viruses escape from cells and spread to infect neighboring cells.

New potential drug target for atherosclerosis

A nuclear receptor protein, known for controlling the ability of cells to burn fat, also exerts powerful anti-inflammatory effects in arteries, suppressing atherosclerosis in mice prone to developing the harmful plaques, according to new research by scientists at the Salk Institute for Biological Studies and the Harvard School of Public Health.

New malaria drug also treats toxoplasmosis

A new drug that will soon enter clinical trials for treatment of malaria also appears to be 10 times more effective than the key medicine in the current gold-standard treatment for toxoplasmosis, a disease caused by a related parasite that infects nearly one-third of all humans—more than two billion people worldwide.

Molecular alliance that sustains embryonic stem cell state

One of the four ingredients in the genetic recipe that scientists in Japan and the U.S. followed last year to persuade human skin cells to revert to an embryonic stem cell state, is dispensable in ES cells, thanks to the presence of a molecular alliance between a specific group of key proteins known as transcription factors, a research team led by the Genome Institute of Singapore (GIS) under the Agency for Science, Technology and Research (A*STAR) reports in the current issue of Nature Cell Biology.

Folic acid consumption before and during pregnancy

Taking a folic acid pill a day — a simple measure to prevent severe birth defects — is under-promoted in the media, under-recommended by health care providers and underused by women of childbearing age, according to a new review of studies.

Alcohol may increase blood pressure to a much greater extent than previously thought

Previous observational studies have reported that heavy alcohol intake is a risk factor for hypertension but such studies may be confounded by factors such as diet, smoking, exercise levels and socio-economic position.

Flat, non-polypoid colorectal neoplasms linked to colorectal cancer

Flat, non-polypoid colorectal neoplasms (NP-CRNs), which may be difficult to detect, appear to be relatively common and may have a greater association with cancer compared with the more routinely diagnosed type of colorectal polyps, according to a study in the March 5 issue of JAMA.
