The Electron Beam CT (EBT) Coronary Calcium Score (CCS) is an independent predictor of coronary events and adds incremental information to standard risk factors. How to use this information was uncertain. To assist our referring physicians in utilizing this test, a web based calculator was created that combines the Framingham score risk with the EBT CCS risk to obtain a new risk for cardiac eve...
Studies of the effects of the chelating agent, calcium acetylamino propylidene diphosphonic acid (Ca-APDA), on the removal of radioactive strontium with two administration modalities were carried out in rats. The parenteral (intraperitoneal) administration of 150, 300, or 600 mg kg(-1) Ca-APDA was carried out for 3 d, 10 min after exposure of the animals to the strontium injection. On the first...
Using 1000 successive points of a pulse wave velocity (PWV) series, we previously distinguished healthy from diabetic subjects with multi-scale entropy (MSE) using a scale factor of 10. One major limitation is the long time for data acquisition (i.e., 20 min). This study aimed at validating the sensitivity of a novel method, short time MSE (sMSE) that utilized a substantially smaller sample siz...
The PCR analysis was performed on DNA samples extracted from a total of 20 individuals using six oligonucleotides primers. The author accomplished clustering analyses to reveal the Euclidean genetic distances among four clam populations from Gochang, Seocheon, Taean and Anmyeon of the Korean peninsula. The oligonucleotides primer OPA-08 generated 5 unique loci to each population, approximately ...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
Abstract Background Among older adults, depression is associated with increased risk of lower physical, social, and cognitive function. Physical Activity (PA) has been odds depression; however, the minimally sufficient dose for protection unknown. Herein, we quantified association between different PA doses depressive symptoms status among adults across 10 years (waves 1-5) as part The Irish Lo...
دزیمترهای ترمولومینسانس به سبب کاربرد وسیعشان در دزیمتریها، از جمله دزیمتری نوترون، شناخته شدهاند. در فلوی نوترونی کم، میتوان بعد از حذف مقدار دز ناشی از پرتوی گاما، مستقیماً از پدیده ترمولومینسانس برای اندازهگیری فلوی نوترون حرارتی و نیمه حرارتی استفاده کرد. در مقادیر زیادتر، به سبب لزوم استفاده از صافیهای کاهنده شدت نور، همچنین پدیده غیرخطی شدن بر اثر جذب دزهای زیاد نوترون و گاما، روش مستق...
