A persistent challenge in solving inverse problems in electrocardiography is the application of suitable constraints to the calculation of cardiac sources. Whether one formulates the inverse problem in terms of epicardial potentials or activation wavefronts, the problem is physically ill-posed and hence results in numerically unstable computations.

BACKGROUND This study was conducted to evaluate the efficacy and side effects of a new regimen of 800 microg misoprostol administered intravaginally every 6 h up to a maximum of three doses in 24 h for second trimester pregnancy termination. METHODS A total of 66 women seeking termination of second trimester pregnancy (30 fetal structural anomaly, six(More)
The aim of this randomized prospective study was to compare efficacy and side effects of saline moistened misoprostol with dry misoprostol, administered 800 μg intravaginally every 6 h up to a maximum of 3 doses in 24 h for second trimester pregnancy termination. A total of 81 women seeking termination of second trimester pregnancy (55 fetal death, 17 fetal(More)
Previous studies have examined the influence of body position, respiration, and habitus on body surface potentials. However, the authors could only estimate the sources of the effects they documented. Among the proposed origin of changes in body surface potentials from those studies were the position of the heart, alterations in autonomic tone, differences(More)
AIM AND SCOPE To investigate the inhibitory effect of subconjunctival application of VEGF antibodies bevacizumab, ranibizumab, pegaptanib, and HER2 antibody trastuzumab on corneal neovascularization in a rat model of experimental corneal neovascularization. MATERIAL AND METHOD Thirty male Wistar albino rats were included in the study. A chemical burn was(More)
To investigate the effectiveness of human amniotic membrane (HAM) in the prevention of postoperative adhesion formation and to compare it with the efficacy of hyaluronate/carboxymethylcellulose (HA/CMC) membrane in a rat model. Following pilot studies and computer-generated randomization, 23 female Wistar albino rats were operated on in the full study. One(More)
The current study was designed to investigate the efficacy of a hyaluronate/carboxymethylcellulose membrane for the prevention of post-operative adhesion in a rat uterine horn model. This is a prospective double-blinded controlled study. Nineteen injured uterine horns were treated with a hyaluronate/carboxymethylcellulose membrane as a barrier and 19(More)
BACKGROUND The study was conducted to compare the levonorgestrel intrauterine system (LNG-IUS) and Copper T380A intrauterine device (IUD) in women with and without adenomyosis and to investigate the effects on menstruation and dysmenorrhea. STUDY DESIGN Women diagnosed as having adenomyosis on transvaginal ultrasound were assigned to receive LNG-IUS(More)
OBJECTIVE We sought to test if metformin could regress endometriotic explants in rats. STUDY DESIGN After inducing endometriotic implants and randomization of female Wistar albino rats, they were given 25 and 50 mg/kg/day of oral metformin in group A (n = 9) and B (n = 8), respectively, for 28 days. Group C (n = 9) was given saline as placebo. RESULTS(More)
Gonadoblastoma is a rare gonadal tumor with tumor cells arranged in nests surrounded by ovarian stroma containing Leydig or lutein-type cells. In 50% of the cases, there is an overgrowth of germ cells with progression to dysgerminoma. A case of gonadoblastoma with coexisting dysgerminoma developing in both ovaries of a 20-year-old girl who had increased(More)
