Phase of clock gene expression in human leukocytes correlates with habitual sleep timing

The phase of clock gene expression in leukocytes, assessed in the absence of the masking effects of light-dark and sleep-wake cycles, correlates with habitual sleep timing, according to a study published in the May 1 issue of the journal SLEEP.

Obesity and heart failure risk

Heart specialists at Johns Hopkins and elsewhere report what is believed to be the first wide-scale evidence linking severe overweight to prolonged inflammation of heart tissue and the subsequent damage leading to failure of the body's blood-pumping organ.

Intensive training for medical staff in Latin American hospitals reduces serious complication of pregnancy

An intensive educational program for physicians and midwives involving 19 hospitals in Argentina and Uruguay dramatically reduced the rate of postpartum hemorrhage, according to researchers from the National Institutes of Health and other institutions.

High blood pressure still sneaking past doctors, Stanford study shows

Despite the well-known dangers of high blood pressure, major shortfalls still exist in the screening, treatment and control of the disease even when patients are getting a doctor's care, according to a study from the Stanford University School of Medicine.

Scientists produce stem cells from ordinary mouse skin cells

Researchers in the United States say they have produced a stem cell made from ordinary mouse skin cells which they have coaxed into becoming three different types of heart and blood cells in mice.

Trends in heart mortality reversing in younger women

Coronary heart disease mortality in younger women could be on the rise, according to findings in the open access journal, BMC Public Health, published by BioMed Central. High levels of smoking, increasing obesity and a lack of exercise could all be contributing to this disturbing trend, seen in women under the age of 50.

FDA needs additional $225 million, new authority to inspect foreign facilities to protect U.S. residents from unsafe prescription drug imports, agency officials say

FDA officials on Tuesday said the agency would need at least $225 million in additional funding annually, along with other authoritative powers, to adequately inspect the safety of imported drug products, the Baltimore Sun reports.

Children more vulnerable to harmful effects of lead at age 6 than as toddlers

Contrary to prevailing assumptions, children are more vulnerable to the harmful effects of lead exposure at the age of 6 than they are in early childhood, according to a Cincinnati Children's Hospital Medical Center study to be presented May 4 at the annual meeting of the Pediatric Academic Societies in Honolulu.

Improving survival rates among users of left ventricular assist devices

Despite the general success of left ventricular assist devices (LVADs) used in critically ill heart failure patients, implantation of these devices often leads to increased bleeding and a need for high-volume blood transfusions during and immediately after surgery.

Alzheimer's and diabetes link

Diabetic individuals have a significantly higher risk of developing Alzheimer's disease but the molecular connection between the two remains unexplained. Now, researchers at the Salk Institute for Biological Studies identified the probable molecular basis for the diabetes - Alzheimer's interaction.

Researchers create heart and blood cells from reprogrammed skin cells

Stem cell researchers at UCLA were able to grow functioning cardiac cells using mouse skin cells that had been reprogrammed into cells with the same unlimited properties as embryonic stem cells.

Scientists discover the double life of proteins

Scientists at The Australian National University are a step closer to understanding the rare Hartnup disorder after discovering a surprising link between blood pressure regulation and nutrition that could also help to shed light on intestinal and kidney function.

AstraZeneca submits sNDA for SYMBICORT in chronic obstructive pulmonary disease

AstraZeneca today announced that it submitted a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) for approval of a new indication for SYMBICORT (budesonide/formoterol fumarate dihydrate) Inhalation Aerosol for the treatment of patients with Chronic Obstructive Pulmonary Disease (COPD). SYMBICORT is currently approved for the long-term maintenance treatment of asthma in patients 12 years and older.

Mothers and offspring can share cells throughout life - with positive and negative effects

Cutting the umbilical cord doesn't necessarily sever the physical link between mother and child. Many cells pass back and forth between the mother and fetus during pregnancy and can be detected in the tissues and organs of both even decades later. This mixing of cells from two genetically distinct individuals is called microchimerism. The phenomenon is the focus of an increasing number of scientists who wonder what role these cells play in the body.

Discovery of quick method for making human monoclonal antibodies against flu

Human monoclonal antibodies (mAbs) - highly specific, identical, infection-fighting proteins produced in large quantities in the lab in cell lines that are derived from a single antibody-producing cell - against influenza can be rapidly produced in the lab, according to a new report from scientists supported by the National Institutes of Health (NIH).

Parents who just prayed as child was dying charged with murder

The parents of a diabetic girl in the U.S. who died as her parents prayed for her recovery rather than seek medical help, have been charged with second-degree reckless homicide.

Ranibizumab therapy for diabetic eye disease shows promise

A JDRF collaboration between Johns Hopkins researchers and Genentech has shown that a drug for the treatment of diabetic eye disease has performed better in clinical trials than the current standard treatment using laser surgery.

Study explains why steroid therapy for sinusitis and asthma loses its punch over time

Scientists at Johns Hopkins have outlined a new path for potential therapies to combat inflammation associated with sinusitis and asthma based on a new understanding of the body's earliest immune response in the nose and sinus cavities.

Yale scientists explain metastasis

Metastasis, the spread of cancer throughout the body, can be explained by the fusion of a cancer cell with a white blood cell in the original tumor, according to Yale School of Medicine researchers, who say that this single event can set the stage for cancer's migration to other parts of the body.

Hydrogen sulphide may be involved in regulating blood pressure

Hydrogen sulphide is a gas most commonly associated with the smell of stink bombs, sewage and rotten eggs, but a team of researchers from the Peninsula Medical School in the South West of England and King's College London have now identified a role for this gas in regulating blood pressure, according to research published in the leading science journal "Circulation".
