...ing no-flow ischemia. Baseline liver biopsies were harvested from anesthetized three-day-old male (n=4) and female (n=6) piglets and immediately afterward the liver was excised and placed in a normothermic bath for 45 minutes. Biopsies were then taken at 15, 30, and 45 minutes of ischemia. All biopsies were an...

Renewable energy wrecks environment

... of the USA, vast areas would need to be shaved or harvested annually. To obtain the same electricity from biomass as from a single nuclear power plant would require 2500 square kilometers of prime Iowa land.

Killing only a few animals won't do any harm -- or will it?

... Kooten and co-workers predict for example that in harvested cannibalistic fish populations, individuals may reach giant sizes, more than double the size of those in unharvested population. Indeed, such giant cannibals seem to occur frequently in heavily fished lakes. Our results are directly applicable to con...

Tick-related disease thrives on cholesterol, study suggests

...s collected blood samples from each mouse and also harvested each animal's spleen and liver. They determined the extent of the infection based on the amount of bacteria found in each tissue. Since the spleen and liver both filter blood, and the liver makes and stores cholesterol, the researchers thought that t...

On-farm research shows farmers that they can use less nitrogen

...8 tons of corn silage on my clay soils, so when we harvested 20 tons in 2006, I was excited." This year, Kiechle is applying half the nitrogen he used last year. "This on-farm research trial showed I was just wasting money to apply more. I cut back, and that has saved me about $10-$12 per acre." And when far...

UVa researchers restore genes in human inner ear cells
