Study links inflammation and calcium signaling in heart attack

A new study led by University of Iowa researchers has found an unexpected new link between this inflammation in heart muscle following a heart attack and a previously known enzyme called calcium/calmodulin-dependent protein kinase II or CaM kinase II.

Curry ingredient curcumin makes membranes behave for better health

Revered in India as "holy powder," the marigold-colored spice known as turmeric has been used for centuries to treat wounds, infections and other health problems.

Brain tumor treatment may increase number of cancer stem-like cells

A new study suggests that the standard treatment for a common brain tumor increases the aggressiveness of surviving cancer cells, possibly leaving patients more vulnerable to tumor recurrence.

Increasing risk of HIV among seniors

People ages 50 and older are more likely to have unprotected sex than younger groups, increasing their risk for HIV and other sexually transmitted infections, according to a recently released World Health Organization study, Reuters UK reports.

Why does aspirin increase the susceptibility of Helicobacter pylori to antimicrobials?

Resent studies reported that aspirin inhibited the growth of H. pylori in a dose-dependent manner and significantly affected the activity of virulence factors of H. pylori.

Discovery of new potential therapeutic target for Barth Syndrome

Researchers at NYU Langone Medical Center may have discovered a new targeted intervention for Barth Syndrome (BTHS).

Scientists measure impact of high-fat diet on the spread of cancer

Researchers at Purdue University have precisely measured the impact of a high-fat diet on the spread of cancer, finding that excessive dietary fat caused a 300 percent increase in metastasizing tumor cells in laboratory animals.

Chili Peppers continue to help unravel mechanism of pain sensation

Capsaicin, the active ingredient in chili peppers, generally is viewed as an irritant that produces a burning sensation when applied to a sensitive area of the body, such as the cornea.

Mathematical method helps to select human embryos

A team of researchers from the University of the Basque Country (UPV-EHU) have developed a mathematical classification which makes it possible to select human embryos for use in assisted reproduction treatments. Scientists have used the morphology of embryos to select the best candidates for implantation in the woman's uterus.

Scientists identify lab-made proteins that neutralize a broad range of influenza A viruses

Scientists have identified a small family of lab-made proteins that neutralize a broad range of influenza A viruses, including the H5N1 avian virus, the 1918 pandemic influenza virus and seasonal H1N1 flu viruses.

Calcium linked to lower risk of cancer in women

Women with higher intake of calcium appear to have a lower risk of cancer overall, and both men and women with high calcium intakes have lower risks of colorectal cancer and other cancers of the digestive system, according to a report in the February 23 issue of Archives of Internal Medicine.

Targeted nanospheres find, penetrate, then fuel burning of melanoma

Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light. When heated with lasers, the actively targeted hollow gold nanospheres did eight times more damage to melanoma tumors in mice than did the same nanospheres that gathered less directly in the tumors.

Nanoparticles detect dying cancer cells

Two years ago, researchers at the University of South Australia discovered a new molecular marker specific for chemotherapy-induced cancer cell death. Now, those same investigators have used this marker to develop an imaging agent that can pinpoint tumor cell death using magnetic resonance imaging.

Scientists identify human monoclonal antibodies effective against bird flu

Researchers at the Dana-Farber Cancer Institute (Dana-Farber), Burnham Institute for Medical Research (Burnham) and the Centers for Disease Control and Prevention (CDC) have reported the identification of human monoclonal antibodies (mAb) that neutralize an unprecedented range of influenza A viruses, including avian influenza A (H5N1) virus, previous pandemic influenza viruses, and some seasonal influenza viruses.

High-flux hemodialysis prolongs survival in chronic kidney disease

High-flux hemodialysis (which removes large toxins) reduces the risk of premature death in many patients with chronic kidney disease (CKD), according to a study appearing in the March 2009 issue of the Journal of the American Society Nephrology (JASN).

Researchers study Actin - a globular protein

Actin, a globular protein found in all eukaryotic cells, is a workhorse that varies remarkably little from baker's yeast to the human body.

Faster detection of viruses with nanodevices

A more specific and faster detection of viruses has been identified in new research by Trinity College Dublin's Professor of Physics, Martin Hegner at Trinity College's Centre of Research on Adaptive Nanostructures and Nanodevices (CRANN) and an international team of researchers.

Boosting its infectivity turns benign virus into good gene therapy carrier for cystic fibrosis

Researchers from the University of California, Berkeley, and the University of Iowa have turned a relatively benign virus into a highly infectious form that is ideal as a carrier for gene therapy.

Molecules self-assemble to provide new therapeutic treatments

Researchers in the laboratory of Samuel I. Stupp at Northwestern University have an interesting approach for tackling some major health problems: gather raw materials and then let them self-assemble into structures that can address a multitude of medical needs.
