Mouse Study Suggests Anxiety Disorders Take Root in Infancy

.... The resulting line of double-transgenic "rescue" animals expressed the serotonin receptors only in the forebrain, but exhibited normal anxiety behavior. Further tests, in which the drug doxycycline was used to suppress the receptors in mice at various stages of development, showed that eliminating the rece...

Study Finds Prion Proteins in Milk

...rions in milk implies a possibility that milk from animals with TSEs serves as a source of infectious prions. The study found that the absolute amount of normal prion proteins in milk differed among species, with sheep milk containing more than human milk. The study also identified prions in homogenized an...
