Whether pregnant women with conditions ranging from ulcers to AIDS should keep taking the same doses of medicine they took before pregnancy is a question Medical College of Georgia researchers want answered.
They are betting they’ll find that to maintain efficacy, pregnant women will need higher doses and that the placenta, a 2-pound temporary organ of pregnancy, is why.
“The idea that we are developing is that pregnant women are so different from non-pregnant women in ter
What kind of mysteries and scientific intrigue await the European Space Agencys Venus Express once it has left Earth for its nearest planetary neighbour in 2005? A closer inspection promises to reveal a planet that is hugely different from our own despite a few similarities.
Astronomers often call Venus the Earths twin because both are about the same size and have the same mass. In other ways, however, Venus seems to be an altogether different class of planet. Scientists are keen
Molekularabdrucke in Polymermaterialien als Reaktionsgefäße für die Pharmaforschung
Materialien mit winzigsten Hohlräumen, die andere Moleküle als “Gäste” aufnehmen können, spielen eine bedeutende Rolle in Wissenschaft und Technik. Ein besonders interessantes Verfahren zur Herstellung von Materialien mit passgenau zugeschnittenen Hohlräumen ist das so genannte “Molecular Imprinting”. Die als spätere Gäste vorgesehenen Moleküle werden dabei als Schablone eingesetzt: In ihrer Gegenwart
Ein Verfahren zur schnelleren Analyse von Wasserverschmutzung hat die australische Griffith University in Zusammenarbeit mit der Lincoln University in Neuseeland entwickelt. Organische Verschmutzungen können jetzt innerhalb einer Stunde nachgewiesen werden.
Bei der alten und bei der neuen Methode wird die organische Verschmutzung anhand des biochemischen Sauerstoffbedarfs in einer Wasserprobe gemessen. “Das bisherige Messverfahren dauert aber fünf Tage”, sagt Dr. Richard John vom Institut f
Exosomes are minute, natural membrane vesicles secreted by various types of cells of the immune system. They are of enormous interest to oncologists, who are now using them in clinical trials as tumor-antigen bearers to trigger tumor rejection by the body.
On the basis of studies in vitro and in mice, INSERM doctors and research scientists at the Institut Curie proposed a novel mode of functioning of exosomes in the December 2002 issue of Nature Immunology. It seems that exosomes can indire
Airplane wings or railway rails are examples of mechanical components constantly submitted to stress. They consist of materials (metal alloys) with properties that may change under stress. To understand and improve such materials, it is essential to observe them on a microscopic scale. The ESRF and the ILL make today a step forward into looking deep inside engineering components. Thanks to the use of complementary neutron and synchrotron X-ray beams, these two centres offer a unique tool to measure s
