Scientific breakthrough: What caused the extinction of the woolly rhinoceros ten thousand years ago from an area in Europe covering the coasts of the Arctic Ocean in the north to the coasts of the Mediterranean in the south?
Clinicians should carefully weigh the risks and benefits of when to administer platelet glycoprotein IIb/IIIa (Gp IIb/IIIa) inhibitors for patients with acute coronary syndromes undergoing invasive treatment, according to a study in the February 14 issue of JAMA.
Genetic testing for eye disease is providing vital information about complex retinal diseases, especially when used to confirm a clinician?s diagnosis, according to a newly published study of such tests that were conducted over a five-year period.
A new research laboratory at Rutgers University?Camden seeks to determine how children develop cognitive skills, how cultural heritage can shape psychological perspectives, and the role memory plays in making judgments.
An unsubstantiated but well-publicised claim by The Gambia’s President Yahya Jammeh that he can cure AIDS risks setting back efforts to stop the virus from spreading in the tiny West Africa nation and the region, campaigners warn.
Using a nuclear transfer procedure, scientists at Rockefeller University and the Howard Hughes Medical Institute have, for the first time, shown reproducibly that mice can be cloned from adult stem cells.
The U.S. Food and Drug Administration (FDA) today announced it has cleared for marketing in the U.S. the TephaFLEX Absorbable Suture?the first absorbable polymer suture made from material isolated from bacteria modified by recombinant DNA technology.
Among patients with retinal disease, molecular testing can confirm a clinical diagnosis of hereditary disorders, identify carrier status and confirm or rule out the presence of a familial mutation in those without symptoms, according to a report in the February issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
Healthy and viable mice that survive until adulthood have, for the first time, been cloned from adult stem cells. Scientists from Rockefeller University, including Howard Hughes Medical Institute investigator Elaine Fuchs, used cells called keratinocyte stem cells, which represent a new model system for cloning. Keratinocytes come from the skin, making them a particularly attractive stem cell source because of their ready accessibility.
In hospitals today, the first warning that a post-operative patient is going into septic shock is often when the patient’s blood pressure collapses and congestive heart failure begins. By that time the patient has a high probability of dying, or if he survives, an even higher probability of permanent major organ damage after a long stay in an intensive care unit.
