OBJECTIVE To evaluate the value of conventional ultrasound and contrast-enhanced ultrasound (CEUS) in determining the severity of active Crohn's disease. METHODS Thirty-seven patients who were considered to be in active period of Crohn's disease were included. Conventional ultrasound was employed to measure the thicknesses of interior, exterior and the whole bowel walls. Qualitative and quant...
Background: Brucellosis is a world-wide disease, which has a diverse clinical manifestation, and its diagnosis has to be proven by laboratory data. Serum agglutination test (SAT) is the most-widely used test for diagnosing brucellosis. The enzyme linked immunosorbent assay (ELISA) can also determine specific antibody classes against brucella. It is a sensitive, simple and rapid test, which coul...
هدف: مقایسه خواص نوری لنزهای درون چشمی حاوی مواد جذب‌کننده پرتو فرابنفش و تعیین ترکیبات شیمیایی آن‌‌ها. روش پژوهش: لنزهای درون چشمی گوناگون شامل لنزهای آکریلیک هیدروفیل انعطاف‌پذیر، هیدروفوب انعطاف‌پذیر و هیدروفوب غیر‌قابل‌انعطاف PMMA (پلی‌متیل‌متاکریلات) در سه عدد دیوپتر 15، 22 و 25 مورد بررسی قرار گرفتند. بررسی خواص نوری با روش طیف‌سنجی (UV-Visible) UV-VIS در طول موج‌های بین nm 800-200...
Wheat grain yield reduction occurs in most wheat growing regions of Iran due to post-anthesis water stress. This research was conducted to evaluate yield and yield components of wheat cultivars in normal irrigation and post anthesis irrigation cut-off conditions as a split-plot arrangement based on a randomized complete block design with three replications during 2015-16 in College of Agricultu...
Extended Abstract. Sampling is the process of selecting units (e.g., people, organizations) from a population of interest so that by studying the sample we may fairly generalize our results back to the population from which they were chosen. To draw a sample from the underlying population, a variety of sampling methods can be employed, individually or in combination. Cut-off sampling is a pr...
