Association of anticardiolipin antibodies levels with instent restenosis in patients with coronary artery disease.

Present study was conducted to evaluate the association of IgG anticardiolipin antibodies with instent restenosis in patients having undergone percutaneous intervention with bare metal or drug eluting stents. Coronary artery disease patients with stent placement at least 6 months prior were screened for eligibility. 26 satisfied the inclusion/exclusion criteria.

Simulation of physiology experiments--an alternative to animal use.

Amphibian experiments on nerve-muscle preparation and heart are essential as per first year MBBS practical syllabus, for learning basic concepts in Physiology. Need was felt to design and develop computer based simulation software as an alternative to animal use, due to growing concern and stringent laws imposed by animal ethical bodies. Computer algorithms were developed for 13 amphibian experiments, by manually tracing the graphs obtained through mechanical experimentation and storing the X, Y coordinates for the end points of each line segment as data base tables.

Assessment of respiratory and sympathetic cardiovascular parameters in obese school children.

The study was undertaken to assess the respiratory and sympathetic cardiovascular functions in obese and non obese school children of 12-16 years age group, randomly selected from two schools of Rajpura (Punjab), representing mixed socioeconomic group of Punjabi ethnicity and categorized as obese or controls as per standard criteria for Body Mass Index (BMI). Dynamic lung function tests and pressor response to cold (Cold pressor test) and isometric exercise (Handgrip dynamometer test) were carried out. Statistical analysis comprised students' t-test, at 95% confidence level and simple linear regression analysis.

Therapeutic efficacy of basic fibroblast growth factor on experimental focal ischemia studied by magnetic resonance imaging.

The purpose of this study was to evaluate the effect of intravenous infusion of basic fibroblast growth factor (bFGF) in a permanent ischemia model at the subacute phase (2 weeks) as well as at 24 hours and 1 week using T2-weighted magnetic resonance imaging (MRI). The middle cerebral artery (MCA) in Sprague-Dawley rats was occluded using an intraluminal suture method. The rats were randomly divided into 2 groups to receive either bFGF (45 mircrog/kg/hr) or saline solution.

Retention of ovaries and oxidative stress of surgery.

Objective: Surgical menopause results in severe menopausal symptoms due to the sudden withdrawal of estrogen. This study evaluated the impact of surgical menopause on oxidant and antioxidant status.

Methods: Thirty eight women who underwent total hysterectomy with or without bilateral salpingo-oophorectomy were included.
