OBJECTIVE To study the differences in the cleavage time between chromosomally normal and abnormal embryos and to elaborate an algorithm to increase the probability of noninvasively selecting chromosomally normal embryos. DESIGN Retrospective cohort study. SETTING University-affiliated infertility center. PATIENT(S) Preimplantation genetic screening patients (n = 125; n = 77 with ET), incl...

The objectives of the present study was to standardize the protocol for production of functional pork loaves and to assess the economics of production of the developed product.Four treatments were prepared with incorporation of inulin powder (IP) as fibre source viz. Control (0% IP; C), 1% (T1), 2% (T2) and 3% (T3) by replacing the amount of lean meat in the product formulation. Different batch...

Pathology of the thyroid gland tissue was characterized in patients with Triiodothyronine (T3)-predominant Graves' disease who had normal levels of serum T4 but increased levels of serum T3 during antithyroid drug therapy. In order to compare this group of patients with an usual type of Graves' patients, age, sex, dietary intake of iodide, duration of antithyroid therapy and the dose of thionam...

The protective effects of oxymatrine (OMT) on apoptosis and heat shock protein 90a (Hsp90a) expression in a rabbit model of lung ischemia-reperfusion injury (LIRI) were investigated. The model of LIRI was established in rabbits and they were randomly divided into two groups: The control group (group C, n=10), and experimental group (further divided into groups E1, n=10; and group E2, n=10), to ...

Two important features of amphibian metamorphosis are the sequential response of tissues to different concentrations of thyroid hormone (TH) and the development of the negative feedback loop between the pituitary and the thyroid gland that regulates TH synthesis by the thyroid gland. At the climax of metamorphosis in Xenopus laevis (when the TH level is highest), the ratio of the circulating pr...

BACKGROUND Clinical and experimental data have suggested a potential negative impact of low-T3 state on the prognosis of cardiac diseases. The aim of the present prospective study was to assess the role of thyroid hormones in the prognosis of patient population with heart disease. METHODS AND RESULTS A total of 573 consecutive cardiac patients underwent thyroid function profile evaluation. Th...

AIM The aim of the present study was an in vivo evaluation of the wear of different sealing materials using the replication technique. MATERIALS AND METHODS Four different sealing materials were randomly applied on 2 out of 4 caries-free permanent first molars of each patient. Impressions were taken at T0: before the sealing material was applied; T1: right after the application; T2: 6 months ...

The beta-amyloid protein (Abeta), the major component of the senile plaques found in Alzheimer brains, derives from a larger beta-amyloid precursor protein (APP). Alternative splicing of the APP gene yields three major APP messenger RNAs (mRNAs), which, in turn, give rise to the APP770, APP751, and APP695 protein isoforms. In this study we examined the effects of thyroid hormone on APP expressi...

Thyroid function decreases and cold exposure response becomes impaired with increasing age. We investigated the age-related changes in thyroid structure and function and cold-induced changes in the thyroid activity of aging rats. Thirty-two male Sprague-Dawley rats were randomly divided into four groups (8 rats per group): young (7 months) and old (22 months) groups exposed to room temperature ...
