Agricultural antibiotic use contributes to 'super-bugs' in humans

... rate to potentially contaminated food, and a very low probability of transmission at a given meal." Nevertheless, based on the analysis presented in PLoS Medicine, the authors suggest that "transmission from agriculture can have a greater impact on human populations than hospital transmission." After f...

Less virulent strains of avian influenza can infect humans

...aks involved two serotypes of avian influenza: one low and one highly pathogenic H7N1 and a low pathogenic H7N3 virus. Seven individuals exposed to the more recent outbreak of low pathogenic H7N3 ...

Experimental shingles vaccine proves effective in nationwide study

...olerated, with the rates of serious adverse events low and local reactions at the vaccination site generally mild. "As people live longer, and the proportion of older people in our population increases, it is highly likely that the prevalence of shingles will increase. A preventive shingles vaccine woul...

Genetically modified maize not found in southern Mexico

...panies in the United States that can test for very low concentrations of transgenic material in maize seeds. The researchers were looking for traces of two key transgenes ?one or both of which are found in all GM maize crops. Test results showed no evidence of the presence of either transgene from any o...

Tiny avalanche photodiodes target bioterrorism agents

...d out by the ozone layer providing for a naturally low background signal. Solar-blind APDs are intrinsically able to take advantage of this low background level, while PMTs must use external filters to become solar-blind. This makes secure batt...

Eliminating bacterial infections out of thin air

... bacteria killing is increased under conditions of low oxygen due to HIF-1 upregulation, and that bacterial infection upregulates HIF-1. In fact, upregulation of HIF-1 enhances expression of bactericidal agents and killing of bacteria. This reveals that a novel approach to treating bacterial infection i...

New book expands biological classifications to account for 'alien' life

...mpounds such as ammonia that remain liquid at very low temperatures. Ward is one of several faculty members in the UW's groundbreaking graduate program in astrobiology. The program, the first of its kind, started in 1998 with a grant from the National Science Foundation and has since been bolstered by f...

Stolen gene allows insect virus to enter cells

...as a diarrheal-type virus, reproducing itself at a low level in the gut, letting the host survive," Blissard hypothesizes. "Picking up the f gene may have caused a radical change in the pathology of this virus, because a virus that co-exists nicely with its host will function a lot differently than one t...

Metal-containing compounds show promise as HIV weapon

...nging off them. The researchers found that at very low concentrations, the new molecules inhibit protease in infected cultured human cells with no obvious toxicity toward the cells. The 12-pointed, cagelike molecule of boron bound to carbon, called carborane, has been known for more than 50 years but ju...

Does manganese inhaled from the shower represent a public health threat?

... have developed manganese poisoning even at fairly low doses in their water supplies, Spangler said. The Environmental Protection Agency (EPA) has set 0.5 milligrams/liter as the upper limit of manganese advisable in water supplies. The limit, however, is based on odor and taste of the water. The potent...

U-M scientists discover identifying markers for primitive blood-forming stem cells

...rify HSCs are expressed as a gradient from high to low across the hematopoietic cell hierarchy," says Omer H. Yilmaz, co-first author and a student in the Medical School's M.D./Ph.D. program. "What's really exciting about this finding is that now we have markers that turn on and off abruptly as stem cell...

Costly breeding programs for endangered species pay off

...altered on a 12-hour cycle based upon the high and low temperatures recorded in Houston that day. In both strategies, all breeding lines survived in captivity. In the "wild" setting, four of the inbred populations went extinct, compared to just one extinction for the MAI lines. "Apparently, the stressf...
