Novel plague virulence factor identified

...s continued, given potential use of Y. pestis as a biological weapon, they said. The results of the Duke research will appear Aug. 26, 2005, in the on-line edition of European Molecular Biology Organization (EMBO) Reports to be published in print in October.

Anthrax inhibitors identified by Burnham team

...acillus anthracis ("anthrax") is a proven agent of biological terrorism. Pulmonary anthrax, in which spores of the anthrax bacteria are inhaled, is typically fatal unless diagnosis is made at an early stage of infection, when antibiotics such as Ciprofloxacin can provide a complete cure. At late stages in the d...

Researchers seek to discover what really happens when a virus enters the body

...e concerned with damage detected on the basis of a biological cell's death than with the introduction of foreign invaders, such as viruses. If Matzinger is correct, then decades of scientific and medical diagnostic thinking could be in jeopardy. As immunologists consider the relatively new concept, a new NIH ...

Attacks of King George III's madness linked to key metabolism molecule

...by feedings of sugar and high-carbohydrate food. A biological explanation for these nutritional effects has been lacking. The Dana-Farber scientists say in a report featured on the cover of the August 26 issue of Cell that the nutritional component of porphyria involves a key master metabolic molecule, PGC-1 a...

Compound might defeat African sleeping sickness, clinical trial beginning this month

... because they can cross the blood-brain barrier, a biological wall that protects the nervous system naturally but can block beneficial drugs, he said. Work is also progressing rapidly on a new drug for drug-resistant malaria, another major threat in developing countries. The UNC-led Consortium to Develop New D...

Size matters: Preventing large mammal extinction

...ed. Larger mammals have the additional pressure of biological disadvantages such as long gestation period and late weaning age to contend with, significantly increasing their susceptibility to extinction. "In a world dominated by people, being big is substantially more of a disadvantage than we realised, which...

Pregnant women at higher risk for HIV, Uganda study finds

... suggest that the increased risk was likely due to biological changes during pregnancy. "We cannot generalize our findings beyond the Rakai setting and it would be important for other investigators to verify our results. However, if women are at increased risk of HIV acquisition during pregnancy, our findings ...

Space matters: Estimating species diversity in the fossil record

...ionally relied on to identify patterns of existing biological diversity is a long-established rule of thumb called the species-area effect: the tendency for species number, or richness, to increase in a predictable way with area. Paleontologists have been unable to account for the species-area effect, or to eve...
