Background : Identifying the risk factors of recurrence of a disease is important both for physicians and patients. Analyzing the first recurrence may lead to an inaccurate evaluation of risk factors as it may not reflect the history of disease completely and may result in the loss of some valuable information. This study was aimed to analyze the time up to the recurrent relapses of schizophr...
امروزه با توجه به افزایش تقاضا و کاهش منابع انرژی، ذخیره سازی انرژی امری ضروری به نظر می¬رسد و مواد تغییر فاز دهنده وسیله مناسبی برای این منظور بشمار می¬روند. نقطه ضعف این مواد پایین بودن هدایت حرارتی آنهاست و یکی از راههای برطرف کردن این عیب، افزودن نانوذرات به این مواد است. در این پژوهش اثر نانو ذرات بتا سیلیکون کاربید بر خواص حرارتی ماده تغییر فاز دهنده پلی اتیلن گلیکول مورد مطالعه قرار گرفت...
Background: Coronary artery diseases (CAD) is the most common cause of death in the developing counteries. Atherosclerosis is the leading cause of CAD. A number of studies have shown that total leukocyte count is a risk factor for CAD but there is little information on the role of eosinophilia and allergy. The aim of this study was to determine the relationship between eosinophilia and histor...

The present study aimed at evaluating patients with occupational allergic contact dermatitis (ACD) caused by common allergens based on occupation type and disease history. Methods: This cross-sectional study aimed at evaluating the data of the patients with probable diagn...
The many types of pulmonary hypertension (PH) are so protean in their biological origin, histological expression, and natural history that it is difficult to create a summary picture of the disease, or to easily compare and contrast characteristics of one type of PH with another. For newcomers to the field, however, such a picture would facilitate a broad understanding of PH. In this paper, we ...
