Scientists have demonstrated a new way to assess the potentially damaging effects of prenatal drug exposure--a technique that could also be used to monitor a fetus's response to therapeutic drugs--using sophisticated, noninvasive medical imaging tools, reports the February issue of the Society of Nuclear Medicine's Journal of Nuclear Medicine. Scientists used PET combined with MRI to track the uptake and distribution of trace amounts of cocaine in pregnant monkeys.
The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) is establishing six new Research Units in order to promote cooperation between outstanding scientists and researchers in innovative research projects.
The Heart Truth, a national awareness campaign for women about heart disease sponsored by the National Heart, Lung, and Blood Institute (NHLBI), will host the Red Dress Collection 2005 Fashion Show today at Olympus Fashion Week in New York City on National Wear Red Day. With 26 of America's most influential designers and a star-studded cast of celebrity models, the fashion show brings to life the Red Dress, the national symbol for women and heart disease awareness.
In drought conditions, the capacity for retaining carbon in legume nodules is limited and this may be the reason why there is a drop in nitrogen-fixing in legumes under these conditions.
A new study suggests that people with autism may perform unusually well on some tests of visual processing. The researchers found that autistic people were less likely than others to have false memories about images they had seen earlier. The researchers had previously demonstrated this kind of effect with verbal material, but not with visual material.
A technology institute at UC San Diego handed out its first awards to honor undergraduate researchers in bioinformatics.
The final public NIH rule is wasteful of federal research dollars and a missed opportunity to take advantage of available technology and existing efforts, according to leading not-for-profit medical and scientific publishers. These publishers already have policies to provide public access. They proposed that NIH work with them to save money and avoid confusion, but the final rule fails to do so.
The results of the world's first phase 3 HIV vaccine efficacy trial are reported in the March 1 issue of the Journal of Infectious Diseases, now available online. Although the vaccine was ineffective in preventing HIV infection, the trial represents a landmark in the fight against HIV and offers the scientific community a foundation on which to build future trials.
Public interest supporters of the NIH Enhanced Public Access Plan today declared the just-announced policy falls short of their expectations and long-standing recommendations. In a letter addressed to Health and Human Services (HHS) Secretary Michael Leavitt, the Alliance for Taxpayer Access outlined its key concerns with the NIH plan.
With a $10 million competitively bid contract from the U.S. Display Consortium (USDC), Binghamton University, State University of New York, has established the Center for Advanced Microelectronics Manufacturing (CAMM).
Six leading medical institutions, including the Autism Center at the University of Washington, are joining forces with physicians and parents to form the nonprofit Austism Treatment Network.
The use of full-body cardiovascular and tumor MRI to screen for disease in patients who do not have any suspicious symptoms is technically feasible, but for the present, full-body MRI screening should not be performed outside of a research setting due to the uncertainty of whether the benefits outweigh the risks, according to a new study by researchers from the University Hospital of Essen in Germany.
Researchers have identified a promising new target in their fight against a dangerous bacterium that sickens people in hospitals, especially people who receive medical implants such as catheters, artificial joints and heart valves.
A University of Alberta surgeon, well known for his pioneering work in developing the Edmonton Protocol treatment for diabetes, has taken another important step in the fight against diabetes.
The presence of a protein known as Stat5 prevents laboratory-grown breast cancer cells from becoming invasive and aggressive, according to new research from Georgetown University.
Oncologists have long thought that cancer treatments tend to be more effective at certain times of day. But they have been unable to turn this knowledge into practice. Now, researchers have discovered a molecular mechanism that explains why sensitivity to anti-cancer drugs changes with the clock. The findings could lead to new drug treatments that may be more effective because they harness the power and precision of the body's internal clock.
Using magnetic resonance spectroscopy (MRS) for the first time to examine energy production biochemistry in a beating human heart, Johns Hopkins researchers have found substantial energy deficits in failing hearts.
The long-held belief that older people perform slower and worse than younger people has been proven wrong. In a study published today in Neuron, psychologists from McMaster University discovered that the ageing process actually improves certain abilities: Older people appear to be better and faster at grasping the big picture than their younger counterparts.
Scientists have moved a step closer to understanding what happens when cells receive a faulty signal that is known to be a cause of cancer.
Senior social scientists and policy-makers meet in Belfast tomorrow (Friday, February 4) to explore how far the government is succeeding in abolishing child poverty, reducing social exclusion, and improving equal opportunities in Northern Ireland.
Scientists have discovered that factors such as human immunity and drug resistance are less important to the success of bacterial spread than previously thought.
Proteins called coactivators control the process by which a single gene can initiate production of several proteins in a process called alternative splicing, said Baylor College of Medicine researchers in a report that appears in today's issue of the journal Molecular Cell.
A pro-inflammatory protein activated by bacteria in the colon plays a key role in the development of experimental colitis in mice - a mouse-version of human Crohn's disease - according to research by scientists at the University of California, San Diego (UCSD) School of Medicine.
New guidelines restricting GPs from referring patients for endoscopy - a hospital procedure to check for cancer of the gullet or stomach - put patients at risk, says a letter in this week's BMJ.
Those most at risk of dying from sudden cardiac death in England are offered the least protection from available preventative measures, say researchers on bmj.com this week.
