Do you have an aversion to the seed head of the lotus flower or honeycomb? If so, you might also get nervous about the situation that you are looked at by many people. The traits which make you uncomfortable with them are social anxiety and trypophobia
Hemophilia B is a rare, and recessive X-linked disease characterized by a deficiency of coagulation factor IX. A safe non-viral transfection method based on nucleofection to express and secrete human clotting factor IX, was used.
hFIX levels in the blood of NSG mice injected with ASCs transfected with this vector, were 2.7 ng/mL 48 hours after injection.
Exercise is an effective method of reducing workplace burnout and psychological stress. Cardiovascular exercise reduced negative feelings of burnout and stress. Resistance exercise helped to promote positive aspects of emotional well-being and self accomplishment.
Some mutations are harmful to an organism, yet under certain circumstances can protect an individual when challenged by disease or toxins. Identifying the environment in which this unusual type of diversity is maintained can be difficult. During a high-mortality pandemic of “sea star wasting disease” we identified an association between such diversity in an elongation factor gene, and the health of ochre sea stars (Pisaster ochraceus). Individuals carrying this diversity may be better able to survive the current pandemic, but with important fitness costs for the species as a whole.
Six wildlife species of amphibians, fish and birds were sampled and screened for organohalogen contaminants (OHCs) in a paddy field in Yangtze River Delta, China. High contaminations of chlorinated paraffins were found particularly in terrestrial species. A novel pattern of PCBs with relatively high contribution from octa-CBs to decaCB was observed. A new group of OHCs, with 5–8 chlorines, were found but are not yet structurally confirmed. DDTs was the major organochlorine pesticide contaminant in wildlife. The results show an extensive contamination of OHCs in wildlife in Yangtze River Delta, calling for further (eco)toxicology study and environmental monitoring.
There are two models for reducing the impact of agriculture on biodiversity: land sparing and land sharing. Their success depends on edge effects and fragmentation of patches of farm vs habitat. Land sparing worked the best for preserving biodiversity in birds.
