زمینه و هدف: این مطالعه به منظور تعیین اثر شاخص توده بدنی و تاریخچه باروری (سن، سن منارک، تعداد زایمان، تعداد سالهای باروری، تعداد سالهای یائسگی و سطح سرمی استرادیول، تستوسترون و گلوبولین متصل به هورمون های جنسی) بر سنجش تراکم استخوان مهرههای کمری و گردن استخوان فمور در زنان یائسه سالم انجام شد. مواد و روشها: در این مطالعه توصیفی مقطعی 190 زن یائسه 64-40 ساله که بیماری زمینهای، بیماری موثر...
background: some studies have shown the possible role of protein‑energy malnutrition (pem) in persistence of endemic goiter in iodine replenished areas. the present study was conducted to assess the association between pem and goiter in schoolchildren of isfahan, iran. methods: in a cross‑sectional study using multistage cluster random‑sampling, 2331 schoolchildren with age ranged from 6‑13 yea...
Today we are riding the crest of a wave of converging new neuroscience In the physics of source localization the forward solution is where a source inside a sphere determines the electrical potential on the surface as calculated using Maxwell's 1864 equations. In contrast, the inverse problem is where the sources are unknown and the location of the sources are estimated by measuring the electri...
مقدمه : سرطان سینه از جمله شایعترین بدخیمی ها در زنان ایرانی می باشد که میزان بروز آن 09/17% در هر 100 هزار زن می باشد. میزان بقای 5 ساله این بدخیمی در حدود 75% گزارش شده است. سرطان پستان شایعترین علت مرگ در زنان پس از سرطان ریه بوده و شایعترین محل درگیری آن در ربع فوقانی-خارجی سینه می باشد. مبتلایان به سرطان سینه به دلیل مصرف داروهای مختلف از جمله مهارکننده های آروماتاز در معرض ابتلا به کاهش چ...
We conduct a field experiment to test whether (and how) emotional intelligence can be taught effectively in a short course. We randomly assign MBA students to an emotional intelligence course, a resiliency course, and a “placebo” course. We compare their emotional intelligences, as measured by the MSCEIT, before and after the sixteen-hour course. We find that students in the emotional intellige...
Pairwise and network meta-analysis (NMA) are traditionally used retrospectively to assess existing evidence. However, the current evidence often undergoes several updates as new studies become available. In each update recommendations about the conclusiveness of the evidence and the need of future studies need to be made. In the context of prospective meta-analysis future studies are planned as...
Recent studies of mammalian transcriptomes have identified numerous RNA transcripts that do not code for proteins; their identity, however, is largely unknown. Here we explore an approach based on sequence randomness patterns to discern different RNA classes. The relative z-score we use helps identify the known ncRNA class from the genome, intergene and intron classes. This leads us to a fracti...
OBJECTIVE To investigate associations of family-related factors with children's breakfast consumption and BMI-z-score and to examine whether children's breakfast consumption mediates associations between family-related factors and children's BMI-z-score. SUBJECTS Ten- to twelve-year-old children (n = 6374; mean age = 11.6 ± 0.7 years, 53.2% girls, mean BMI-z-score = 0.4 ± 1.2) and one of thei...
BACKGROUND Inappropriate feeding practices during infancy may lead to overweight. The aims of this study are to investigate the growth of children in the first 18 months of life; to evaluate the feeding practices of caregivers using developed Young Child Feeding Questionnaire; and to investigate caregivers' feeding attitudes and behaviors associated with infants' weight status. METHODS Six mo...
OBJECTIVE To determine whether previously identified adult obesity susceptibility loci were associated uniformly with childhood BMI across the BMI distribution. DESIGN AND METHODS Children were recruited through the Children's Hospital of Philadelphia (n = 7,225). Associations between the following loci and BMI were assessed using quantile regression: FTO (rs3751812), MC4R (rs12970134), TMEM1...
