Multiple aspects of cornea development, including the innervation of the cornea by trigeminal axons, are sensitive to embryonic levels of thyroid hormone (TH). Although previous work showed that increased TH levels could enhance the rate of axonal extension within the cornea in a thyroxine (T4)-...
Total superoxide dismutase (T-SOD) activity in the hypo- and hyper-T rats markedly decreased. In conclusion, these results indicated that thyroid hormones have an important influence on the modulation of uterine antioxidative status. 展开 关键词: Antioxidative status Nitric oxide Rat Thyroid hormone ...
1. Studies have shown that adenosine transport and adenosine A1 receptors in rat brain are subjected to regulation by thyroid hormone levels. Since the ect... C Brown,M Stetson 被引量: 24发表: 1985年 Effects of Thyroid Hormones on Behavior of Yearling Atlantic Salmon (Salmo salar) The indivi...
T3 and T4 hormone concentrations were changed in both morning and afternoon groups in autumn, win-ter, spring and summer seasons, and this situation was closely related to the reproductive period or moulting of T merula while that seasonal varying temperatures affect the amount of these hormones....
1. The effects of 4 weeks of thyroid hormone treatment on contractile, enzyme-histochemical and morphometric properties and on the myosin isoform composition were compared in the slow-twitch soleus and the fast-twitch extensor digitorum longus (EDL) muscle in young (3-6 months) and old (20-24...
Water consumption, thyroid hormone function, behavioral responses, and skull and jawbone measurements were compared among treatments. Additionally, liver, spleen, genital, and brain imidacloprid concentrations were determined by an enzyme-linked immunosorbent assay (ELISA). Results indicated that 1) control...
Before and immediately after and one hour after exercising blood sampling were taken and was measured the concentration of thyroid stimulating hormone (TSH), thyroxin (T4), and triiodothyronine (T3). To examine changes variance ANOVA test were used and only in T4 hormone, significant difference ...
Increase by 15 mg per day every 2 to 3 weeks to achieve normal serum T3 and T4 levels. Maintenance: 60 to 120 mg per day.Usual Adult Dose for Thyroid Cancer:In follicular and papillary carcinoma of the thyroid: Doses larger than the ones suggested for replacement therapy (30 mg to 120...
DOI2 allows the pituitary and hypothalamus to monitor both plasma T3 and T4 independently and plays therefore a critical role in the feedback regulation of thyroid hormone secretion (Larsen, 1982). DIO3 catabolize thyroid hormones and terminates T3 action and is also influenced by thyroid state (...
Those who incorporate a T3 cytomel (or T4) cycle during such an instance will find that their production of said hormone rapidly and potently evolves, thus leading to astate of equilibrium being restored. This is the “official” purpose of these products at least; an auxiliary function lies ...
