Deficiency of selenium (Se) or alpha-tocopherol (E) creates serious health issues in horses. This study evaluated owner supplementation practices and their efficacy at preventing deficiency in a large population of horses. In addition, common clinical signs of horses presenting to a referral institution who had Se and E testing performed...
Purpose of the Study
In most liberal arts colleges, the majority of students enrolled
are primarily interested in a liberal education. To meet the requirements
of its students, several colleges have introduced a relatively
new program in the sciences; this program is the integrated
science course. This study attempts to...

A new photosystem-II mutant of the green alga Scenedesmus
obliquus D₃, strain PS-28, has been shown to lack a-tocopherol
(vitamin E). The photosynthetic activity of dark grown samples of
PS-28 is about 20% of the wild-type control. Culturing the mutant
at low light intentisites (10⁴ ergs/sec-cm ²) stimulates photosynthetic
activity...
Experiments are reported which demonstrate that a cobalt deficiency
in R. meliloti results in a decreased cytochrome content of
bacterial cells. It is concluded that the effect of cobalt deficiency
on cytochrome content of Rhizobium cells and on the leghemoglobin
content of nodules possibly may be explained by an effect...
