Monensin in ruminant diets increases production of propionic acid. We have tested the hypothesis that propionic acid may be elevated to such an extent by monensin that it cannot be optimally metabolized by the methyl malonyl-CoA pathway requiring vitamin B12 (B12) in the liver. Thus, the effect...
This decrease was similar in magnitude across both sexually mature classes, indicating that costs to the expression of high sperm viability are incurred largely through levels of pre-copulatory investment. Males exposed to immature females produced sperm of low viability at both time points. Although ...

Vitamin B12 is considered to be a safe supplement. At the recommended dosages, toxicity is highly unlikely. Since it is a water soluble vitamin, the body will excrete any excess through the urine. As such, no upper limit of intake has been established yet.[13] It seems that a high vita...
They result from the effects of vitamin B12 deficiency on the nervous tissues. Similarly, the tissue changes found in iron deficiency, and very possibly much of the symptomatology, may be a result of effects produced by the lack of iron on the tissues. Today, I should like to review the ...

(2001) indicated that the energy used for reproduction by the American lobster (Homarus americanus) mainly came from protein, and a high protein diet was conducive to its gonadal development. Rodríguez-González et al. (2009) investigated different dietary protein levels on gonadal development of ...
To improve the oral efficiency of exenatide, we prepared polyethylene glycol-poly(lactic-co-glycolic acid) (PEG-PLGA) NPs modified with Fc (NPs-Fc) for exenatide oral delivery. Exenatide was encapsulated into the NPs by the w/o/w emulsion-solvent evapora
Whereas high-achieving groups strengthened the positive relations between academic achievement and social competence, low-achieving groups facilitated the negative relations between academic achievement and social problems. The results indicate the significance of the peer group for social functioning from a ...
A study was made of the microflora of the gut in rats receiving for 30 days a stock diet with and without aureomycin, or a purified diet alone or with addition of methionine or vitamin B12or aureomycin or vitamin B12and aureomycin. With the purified diet the growth of the rats was greates...
