Free-range use and intestinal parasites in organic/free-range laying hens [PDF]
Journal of Applied Poultry Research, 2023 SUMMARY: Intestinal parasites are commonly found in non-cage laying hens. Some of these parasites reduce welfare and performance. Anthelmintics are not always effective and may lead to residues in eggs and in the environment. The aim of this study was to

Short and Long-Range Electron Transfer Compete to Determine Free-Charge Yield in Organic Semiconductors [PDF]
, 2021 Understanding how Frenkel excitons efficiently split to form free-charges in low-dielectric constant organic semiconductors has proven challenging, with many different models proposed in recent years to explain this phenomenon.

Toxoplasmosis in a Free-ranging Mink [PDF]
Journal of Wildlife Diseases, 2006 A free-ranging mink (Mustela vison), estimated to be 3 mo old, was found on the campus of Michigan State University, East Lansing, Michigan; it exhibited clinical signs of left hind limb lameness, ataxia, head tremors, and bilateral blindness. Histologically, the animal had a mild, nonsuppurative meningoencephalitis and severe chorioretinitis with ...

Science, 2007 Human eggs are in short supply, but much in demand. Many infertile women need donated eggs if they are to bear children. Researchers need eggs for somatic-cell nuclear transfer (SCNT) to try to develop stem cell lines. If SCNT-derived stem cells could be made from patients suffering from devastating conditions such as motor neuron disease, they could ...
