Testing pregnant women for gestational diabetes at 16-weeks of pregnancy is a more efficient way to screen for the disease than the current method of screening women during their third trimester, said Gerard Nahum, M.D., an associate clinical professor at Duke University Medical Center’s department of obstetrics and gynecology.
The earlier tests, Nahum said, allow women at highest risk for gestational diabetes to be identified and treated earlier, possibly heading off complications in both
The event which occurred almost a hundred years ago in Podkamennaya Tunguska has drawn scientists` attention again. What actually exploded at that time in the remote taiga, the power of explosion being equal to the 50-megaton H-bomb? The hypothesis that it was a meteorite or any other extraterrestrial object has not quite satisfied inquisitive minds, since too many puzzles remain unsolved. A geologist Vladimir Epifanov, Siberian Research Institute of Geology, Geophysics and Mineral, reported to the
A team of geologists has determined the age of the oldest known meteorite impact on Earth – a catastrophic event that generated massive shockwaves across the planet billions of years before a similar event helped wipe out the dinosaurs.
In a study published in the Aug. 23 issue of the journal Science, the research team reports that an ancient meteorite slammed into Earth 3.47 billion years ago.
Scientists have yet to locate any trace of the extraterrestrial object itself or the gi
Researchers at Case Western Reserve University report in the August 22 issue of Nature how magnesium activates microscopic ion channels in the membrane of a cell. These particular ion channels are important in controlling blood pressure. Scientists, the researchers say, can use this new finding in the quest to understand how magnesium helps to decrease blood pressure and also treat heart failure and stroke.
Calcium activated potassium channels are important microscopic pathways in the cell
In this month’s Genome Biology, Mitch Kostich and colleagues from the Schering-Plough Research Institute (NJ, USA) have identified and mapped an important group of molecules known as protein kinases. These molecules are central to the communication of information both within and between cells, in a process known as cell signaling. Defective protein kinases are associated with hundreds of human diseases, including some types of cancer, and it is hoped that this map, which shows the relationships betwe
UC Irvine researchers are leading the effort to understand the causes and effects of one of the worlds leading environmental problems — air pollution. They are studying both regional and worldwide air pollution issues, ranging from the effects of freeway exhaust to the role dust storms and forest fires may play. UCI is also involved in a large-scale commuter transportation project designed to cut back on auto emissions and is home to the Air Pollution Health Effects Laboratory, which continues
