We determine the preferences of residents in an ad hoc sample, according to the...

Exercise training improves the aging-induced downregulation of myosin heavy chain (MHC) and sarcoplasmic reticulum (SR) Ca(2+)-ATPase, which participate in the regulation of cardiac contraction and relaxation. Thyroid hormone receptor (TR), a transcriptional activator, affected the regulation of gene expression of MHC and SR Ca(2+)-ATPase. We hypothesized that myocardial TR signaling contribute...

In order to determine the normal values of total IgE in children, 3270 sera were taken from 0-14 year old males and females in different parts of Tehran, the capital of Iran. The technique which was used to measure total IgE was ELISA method using monoclonal anti-IgE antibody. The results of this research indicated that the lower value for IgE was detected in children at birth (X=3.S3 IU/m...

The aim of the present study was to investigate the effects of converting enzyme inhibition by captopril on ECG parameters in aged rats. Four-month-old male rats received captopril dissolved in tap water (0.5 mg/l) or tap water for 2 or 20 months. At the end of treatment, under anesthesia, RR and PR interval, P wave and QRS duration, QT and corrected QT interval were measured in all animals. On...
