Objective: The present this study aimed to determine the proper cut-off points for waist circumference (WC), Waist to height ratio (WHtR) and body mass index (BMI) for early predicting of metabolic syndrome among inactive college students. Materials and Methods: In this cross-sectional study, 126 males (age 20.33±1.71) and 63 females (age 20.36±1.72) with inactive lifestyle parti...
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...
Considering water scarcity in Iran, application of deficit irrigation or water stress on some crops is inevitable. We need to provide appropriate design for deficit irrigation. Furrow irrigation management to obtain high efficiency and uniformity is difficult. Therefore, to investigate the variation of the input discharge, the cut-off time and furrow length that are effective on the efficiency ...
receiver operating characteristics (roc) curves have numerous applications for identifying a cut-off point in diagnostic tests. nonetheless, given that sometimes two cut-off points have to be specified simultaneously, the roc curve can be used to identify such points. the volume under the roc surface (vus) serves as a criterion for the accuracy of diagnostic tests. one of the unfortunate outcom...
abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...
Background: Two questions about diagnostic value of urinary neutrophil gelatin associated lipocalin (uNGAL) in detection of acute kidney injury (AKI) in children have remained unanswered; first, which cut-off point of uNGAL has the highest value in detection of AKI; and second when is the best time for measuring this biomarker in a patient? Accordingly, the present study aimed to conduct a syst...
Abstract Introduction: The purpose of this study was to determine the prevalence of mental disorders among high school students in the city of Rafsanjan in the academic year 2001-2002, and to assess the re- lated demographic factors.Method: 830 students were selected through multistage cluster sampling and their mental health status was assessed by SCL-90-R and for suspicious cases of psychiat...
conclusions the fev1/fev6 ratio can be used as a valid surrogate for fev1/fvc in the diagnosis of airway obstruction, especially for screening purposes in high-risk populations for copd. moreover, fev6 is an acceptable alternative for fvc in detection of restrictive pattern. results this study shows that the current cut-off points used to detect obstruction and restriction can be replaced by fe...
Background & Objective: Preterm labor is a major risk factor of mortality and morbidity in newborns and fetuses. Low birth weight is also a risk factor for mortality and various neonatal diseases. This study aimed to determine the association between the CRP levels in first trimester of pregnancy with low birth weight and preterm labor. Methods & Materials: In this prospective cohort study, ...
