Reverse triiodothyronine (rT3), triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH) values were measured by radioimmunoassay in 40 children with congenital hypothyroidism who were being given levothyroxine (0.05-0.35 mg/day) and in 14 normal controls. In 15 of the children with hypothyroidism the treatment, judged by serum T4 and TSH values and thyrotrophin releasing ho...

Finding alternative feeds, such as sesame hulls and Prosopis juliflora species can attenuate difficulties of feed shortage and reduce the cost of animal feed in arid and semi-arid countries. Thirty-two Black male kids with similar initial weights (BW = 16.7±0.80 kg) and 120±5 d of age, were used to evaluate the effect of replacing barley grains and soybean meal with Prosopis juliflora pods (PJP...

The effects of NaCl, glucose, and thyroid hormone on the production of superoxide (O2*-) within the renal medulla of Sprague-Dawley rats were examined. Responses of intracellular superoxide [O2*-]i in isolated medullary thick ascending limbs (mTALs) were studied using real-time fluorescent microscopy with measurement of the dehydroethidium (DHE) to ethidium (Eth) conversion ratio (Eth/DHE ratio...

OBJECTIVE To analyze the long-term changes in maxillary arch widths and buccal corridor ratios in orthodontic patients treated with and without premolar extractions. METHODS The study included 53 patients who were divided into the extraction (n = 28) and nonextraction (n = 25) groups. These patients had complete orthodontic records from the pretreatment (T1), posttreatment (T2), and postreten...

AIM Among the many biological effects which occur during orthodontic movement, we decided to investigate gingival microcirculation. The aim of the study was to evaluate the biological microvascular response to the application of orthodontic force in vivo. MATERIALS AND METHODS Forty patients (case group) between 9-22 years of age (average± DS 12±3.01) were selected for the study (M/F ratio: 2...

this experiment was performed to determine the role of vitamin e and coenzyme q10 antioxidants on performance and ascites parameters of broiler chicks in cold stress conditions using a completely randomized design with 5 treatments and 5 replicates in each treatment. treatments were: positive control (pc, normal thermal conditions without antioxidants), negative control (nc, cold stress without...

Throughout this investigation the effects of three commonly used agricultural pesticides, endosulfan (an organochlorine), malathion (an organophosphorous) and carbaryl (a carbamate) were studied on circulating levels of T4, T3, and the T3/T4 ratio of the fresh water catfish Clarias batrachus during the vitellogenic ( formation of the yolk of an egg) and post-vitellogenic phases of their annual ...
