The turkey hen, a photosensitive bird, will become photorefractory (PR) during the reproductive cycle and will cease laying despite a stimulatory day length. This response is thought to be "programmed" by hormonal events early in the reproductive cycle. The turkey tom, in contrast, produces semen for extended periods and has not been shown to exhibit PR. We compared hormone profiles following p...

Long-term starvation induces an increase in the protein degradation of skeletal muscle in human and laboratory animals.t'9) Rats subjected to refeeding have demonstrated a reduction in the rate of muscle pretein degradation.'・3・5・6・S・") This decrease in degradation due to refeeding is associated with changes in the plasma concentration of many hormones such as insulin, insulinIike growth factor...

We measured total thyroxin (Tr4), free thyroxin(FT4, total triiodothyronine (TT3), free triiodothyronine (FT3), and thyrotropin (TSH) in serum sampled before and 1, 2, 4, 6, and 8 h after administration of prescribed doses of thyroxin to 12 patients with proven primary hypothyroidism. At 2, 4, and 6 h post-dose, the mean values for 114 and FT4 and also that at 8 h for FT4 significantly (P <0.05...

We used an enzyme immunoassay to determine the normal reference intervals for thyroxin, triiodothyronine, and thyrotropin in groups of children, ranging from newborns to 15-year-olds. Results compared well with those by radioimmunoassay. There were no substantial differences between plasma and serum samples for thyroxin and triiodothyronine, but thyrotropin concentrations differed significantly...

Thyroid hormone state was assessed in a group of postmenopausal women who had received long term treatment with oestrogen. Serum concentrations of total thyroxine, triiodothyronine, and thyroxine binding globulin were raised compared with those in a control group given placebo; serum concentrations of thyroid stimulating hormone did not differ between the groups. Oestrogen treatment resulted in...

A series of tetrahedral oligothiophenes bearing n-hexyl groups at the α-positions of the terminal thiophene rings, (n-C(6)H(13)(C(4)H(2)S)(n))(4)C (Hex-TnTM; n=1-4), has been synthesized by Kosugi-Migita-Stille coupling as a key reaction. Thanks to the improved solubility afforded by the terminal n-hexyl groups, the largest homologue (n=4) was successfully obtained. Whereas the smaller derivati...
