Purpose to examine the effect of a 4-day NO3- loading protocol on the submaximal oxygen cost of both low fit and high fit participants at five different exercise intensities. Methods participants were initially assigned to a placebo (PL; negligible NO3-) or inorganic nitrate-rich (NR; 6.2 mmol nitrate/day) group; double-blind, placebo-controlled, crossover. Participants completed three trials...

Although triiodothyronine (T3) is widely used clinically, preclinical support for its antidepressant-like effects is limited, and the mechanisms are unknown. We evaluated 1) the antidepressant-like effects of T3 in the novelty suppressed feeding test (NSFT), tail suspension test (TST), and forced swim test (FST), 2) the role of presynaptic 5-HT(1A) receptors in the antidepressant-like mechanism...

The glucosinolate autolysis products of crushed seeds of DesclIrainia sophia L. (khakeshi) and Brassica napus L. (shelghem) were administered orally to rats in doses representing 8,16 and 32 gm seeds/kg body weight/day at intervals of 10, 20 and sometimes 30 days. Serum T3 and T4 concentrations were reduced in 10 day•autolysate treated animals in a similar fashion to that found with methim...

The objective of this study was to investigate the impact stimulating embryo during dormancy in incubation period. 450 eggs (Ross 308) were allocated four treatments each with three replicates. as follows: T1 control (without shock), T2 Shocked (40) Millivolts (mV), T3 (50) T4 (75) (mV). A different voltage device used shock egg, after marking a line iron filings ensure electrical conductivity,...

No, we’re not making odds for a horse race or betting at a table in Las Vegas! Readers of my column in P&T might recall my discussions of our nation’s performance in health care in previous issues. I’ve noted, with disappointment, that our health care system does not perform as well as those in other nations we like to compare ourselves with. A report from the Commonwealth Fund that caught my a...

OBJECTIVE The present study was designed to retrospectively evaluate Class I malocclusion cases treated with extraction of the four first premolars, aiming to establish the relationship between the quality of orthodontic treatment outcomes and the long-term occlusal stability. MATERIAL AND METHODS The sample comprised 94 patients of both genders, presenting Class I malocclusion, treated with ...

Twenty-four yearling male local Washera lambs with an average initial body weight of 18.14 ± 1.07 kg were used to assess the nutritional value of Millettia ferruginea. Experimental animals were grouped into six blocks of four animals, and each animal was randomly assigned to one of the four dietary treatment feeds. The treatments used were; Sole natural pasture grass hay (T1), and 150, 300, 450...

Postnatal Sertoli cell maturation is characterized by a pronounced rise in androgen receptor (AR) expression, which increases several fold between birth and adulthood. Since both 3,3',5-triiodothyronine (T3) and FSH regulate Sertoli cell proliferation and differentiation, we have determined the effects of T3 and FSH on AR mRNA expression in cultured Sertoli cells from 5-day-old rats. These cult...

This study was conducted to determine the effects of sumac, yeast, and onion supplementation broiler chicken feeds on performance. Four hundred fifty, one-day-old Ross 308 chicks were obtained from Yagoo Group Hatchery in Sulaymaniyah Province randomly distributed into three treatment groups (150 for each group) with six replicates (each 25 chicks). Chicks raised floor cages (210 × 200 100 cm)....

In order to compare the acute effects of three kinds of antithyroid agents of iodide (I-), propylthiouracil (PTU) and PTU combined with iodide (PTU+I-) on thyroid function in hyperthyroid patients with diffuse goiter, serum concentrations of thyroxine (T4), triiodothyronine (T3), T3-resin sponge uptake (T3-RU) and free thyroxine index (FT4I) were employed as thyroid function parameters. In the ...
