Abstract:

Background: Pesticides contain endocrine disrupting chemicals that have potential to perturb the normal thyroid and reproductive hormone axis. The aim of present study was to estimate the variations in serum tri-iodothyronine (T3) tetra-iodothyronine (T4) thyroid stimulating hormone (TSH) and testosterone levels in occupationally exposed pesticide sprayers in comparison to controls. Methods: For this purpose, blood samples of (n=50) pesticide sprayers were collected from District Layyah, south Punjab, Pakistan. Whereas, samples (n=25) of healthy control subjects were obtained from Univer

Abstract:

We must understand hormonal pathways to solve the global problem of overweight children and adolescents. This study examines the relationship between thyroid hormone levels and body weight in Rawalpindi boys, where childhood obesity/BMI is more prevalent. Thyroid function and body weight have been linked in a few studies. In this case-control study, we recruited 166 boys (both normal and Obese) aged 5-15 from hospitals in District Rawalpindi, Pakistan. Heparinized syringes collected 1.5 ml antecubital blood samples from each subject. Blood plasma was immediately centrifuged following standard

<strong>Aim: </strong>The aim of the present study was to compare thyroid profile of postmenopausal women with those in reproductive age group as well as to find the correlation between age and thyroid profile. <strong>Methods: </strong>The present study was conducted by the Department of Biochemistry, Shree Narayan Medical Institute & Hospital, Saharsa, Bihar, India, for the period of 1 year. The study includes 100 young and middle-aged pre-menopausal women (18-50 years) and 100 elderly post-menopausal women (>50 years). All the subjects enrolled in the study were female

Abstract:

The interrelationship between plasma cortisol levels, iodine-iodide nutritional supplementation, plasma thyroid hormone levels (tri- and tetra-iodothyronine, T3 and T4 respectively), and infection intensity with the sea louse Caligus elongatus were investigated in Atlantic salmon, Salmo salar L., and Arctic char, Salvelinus alpinus (L.). Cortisol-implanted Atlantic salmon had significantly higher mean intensities of sea lice than salmon not implanted with cortisol. Untreated Arctic char had significantly higher plasma cortisol levels and sea lice infections than untreated salmon. Cortisol-impl

Introduction: Sickle cell disease is an inherited red blood cell disorder that leads to oxidative stress with the consequence of damage to certain organs, including the thyroid. Objective: To evaluate changes in serum concentrations of triiodothyronine (T3), tetra-iodothyronine (T4) and thyroid-stimulating hormone (TSH) in subjects with sickle cell disease in the city of Lubumbashi. Methods: This study examined indicators of energy metabolism and a marker of oxidative stress in sickle cell anemia children attending ″The Sickle Cell Care Center (C-fare) ″.

Abstract:

Over the past few years increasing evidence has suggested the nongenomic effects of thyroid hormone, such as the activation of the signal transduction pathways and the activation of nuclear factor-κB by the induction of oxidative stress. The present study was undertaken to investigate the effect of thyroid hormone on human polymorphonuclear leukocytes (PMNLs) which are known as important sources of reactive oxygen species in the circulation. The production of superoxide anion (O2−) and the activity of myeloperoxidase were determined in the presence and absence of several inhibitors of the sign

Abstract:

Introduction and Aim: Hyperthyroidism is a disorder characterized by excessively high amounts of tri-iodothyronine and thyroxine in the bloodstream. TPO is a thyroid-specific antigen. TPO gene mutations affect thyroid hormone synthesis, causing full or partial iodide organification abnormalities. In this study, we aimed to look at the single nucleotide polymorphisms (SNPs) in the TPO gene and find possible relation of these SNPs to the development or prognosis of hyperthyroidism. Materials and Methods: Blood samples were collected from hyperthyroid patients (n=75) and healthy individuals (n=25
