Multiparous Brahman cows (n = 21) were randomly assigned during late fall within BW and body condition score (BCS) to receive either 3.0 mL of corn oil (C; n = 7), 3.0 mg/(cow x d) triiodothyronine (T3) s.c. in 3.0 mL of corn oil (HYPER; n = 7), or 4.0 mg/(kg x d) 6-n-propyl-2-thiouracil (PTU; fed
The stimulation of ethylene production from seedling tissue of Phascolus vulgaris, Helianthus annuus and Zea mays by growth regulators was inhibited by actinomycin D and puromycin and to a lesser extent by 2-thiouracil and p-fluorophenylalanine. It is concluded that the mechanism of action of growth
Polybrominated diphenyl ethers (PBDEs) are used for fire prevention purpose. BDE-209, a congener of PBDEs, is thyroid hormones (THs)-disrupting chemical because of its structural similarity with THs. Testis is considered as THs-responsive organ and is more susceptible to chemical agents during
In the experiments described the following observations have been made: (1) The toxic and diabetogenic action of alloxan increases in rats fed a low protein diet and even more so in the case of a high lard or ox fat diet. (2) The action of these fat diets was corrected by the addition of methionine,
