background : methadone is considered as a good choice for maintenance treatment program (mmtp) in opioid addicted individuals. qt interval prolongation was reported previously in methadone chronic usersespecially in high dose prescription. qt-interval prolongation predisposes patients to lethal dysrhythmia. this is a report of corrected qt(qtc) prolongation due to acute methadone poisoning. to ...

background: the health transition in india reflects the growing burden of cardiovascular diseases. it is well-known that there are significant and meaningful differences in the measured electrocardiogram (ecg) parameters between females and males. specific to ecg diagnosis and ischemia, reports have indicated a higher number of false positive results in female patients than in male patients. th...

In this study, we aimed to investigate reproductive performance in estrus-induced Zandi ewes treated with equine chorionic gonadotrophin (eCG) injection in combination with prostaglandin F2α (PGF2α)and gonadotrophin releasing hormone (GnRH) during non-breeding season. The estrous cycle was synchronized using controlled internal drug release (CIDR) for 12 days. The ewes were randomly assigned to...

Background Non-contrast MRA (NC-MRA) based on bSSFP and slab-selective inversion has become an attractive alternative for imaging renal arteries without the usage of potentially nephrotoxic contrast agent. It typically requires navigator gating or abdominal bellow triggering to alleviate breathing motion artifacts. However, navigator gating significantly complicates and lengthens exams due to i...

PURPOSE ECG-gated CT enables the visualization of motions caused by the beating of the heart. Although ECG gating is frequently used in cardiac CT imaging, this technique is also very promising for evaluating vessel wall motion of the aortic artery and the motions of (stent grafts inside) abdominal aortic aneurysms (AAA). Late stent graft failure is a serious complication in endovascular repair...

background: raw sewage contains various pathogenic organisms including bacteria, viruses, fungus, worms and protozoa. workers at wastewater treatment plants (wwtps) are exposed to these organisms as well as to h2s gas causing many health hazards. objectives: to assess some work-related health effects among wwtps workers with special emphasis on the most common infections as well as cardiopulmon...
