BACKGROUND While several studies have reported an inverse relation between IQ and total mortality rates, little is known about the association, if any, between IQ and disease-specific outcomes, particularly cancer. METHODS A cohort of 959,540 Swedish men who underwent IQ testing at military conscription at around 19 years of age, and who were followed for incident cancer. Hazards ratios for t...
هدف: مقایسه لنزهای داخل چشمی آسفریک Acrysof IQ و Akreos AO از نظر اعوجاج اسفریک (spherical aberration) و حساسیت کنتراست. روش پژوهش: این کارآزمایی بالینی بر روی 37 چشم از 37 بیمار انجام شد که بعد از انجام جراحی فیکوامولسیفیکیشن، به طور تصادفی، تحت کارگذاری یکی از لنزهای AO یا IQ قرار گرفتند. سه ماه بعد از عمل، بهترین دید اصلاح‌شده (BCVA)، اعوجاج اسفریک در اندازه مردمک 4 و 6 میلی‌متر و حساسیت...
Background: Transient neonatal hyperthyrotropinemia (TNH) occurs frequently in areas of iodine deficiency and may affect intellectual function and psychomotor performance. Design: A historical cohort study of intellectual development, psychomotor performance, urine iodine and thyroid function tests, performed in 9 years children with documented TNH at birth and control group. Subjects: Eighte...
هدف: مقایسه لنز داخل چشمی آسفریک AcrySof IQ و لنز داخل چشمی اسفریک Sensar از نظر اعوجاج اسفریک (spherical aberration) و حساسیت کنتراست. روش پژوهش: برای 34 چشم از 34 بیمار، بعد از جراحی آب‌مروارید به روش فیکوامولسیفیکیشن، به طور تصادفی، یکی از لنزهای داخل چشمی IQ یا Sensar کار گذاشته شد. سه ماه بعد از عمل، بهترین دید اصلاح‌شده (BCVA)، اعوجاج اسفریک در اندازه مردمک 4 و 6 میلی‌متر و حساسیت کنت...
Background: abnormal electrolytes concentrations in asthma patients can be attributed to low intake or secondary to asthma medications. Objectives: to identify the pattern of changes in electrolytes concentrations among asthmatic patients and to detect correlations between concentrations of electrolytes and pulmonary function measurements. Materials and Methods: the study involved a control gro...
The internal design of database systems has traditionally given primacy to the needs of transactional data. A radical re-evaluation of the internal design giving primacy to the needs of complex analytics shows clear benefits in large databases for both single servers and in multinode shared-disk grid computing. This design supports the trend to keep more years of more finely grained data online...
This study asked whether intensity of supervision is associated with outcome in preschool aged children with autism (N = 20) who received intensive and early behavioral intervention. Intensity of supervision ranged from 2.9 to 7.8 hours per month per child. Results show a significant correlation between intensity of supervision and improvement in IQ. Thus, intensity of supervision was reliably ...
Introduction: Autism is a heterogeneous neurodevelopmental disorder associated with social, cognitive and behavioral impairments. These impairments are often reported along with alteration of the brain structure such as abnormal changes in the grey matter (GM) density. However, it is not yet clear whether these changes could be used to differentiate various subtypes of autism spectrum disorder ...
IQ predicts many measures of life success, as well as trajectories of brain development. Prolonged cortical thickening observed in individuals with high IQ might reflect an extended period of synaptogenesis and high environmental sensitivity or plasticity. We tested this hypothesis by examining the timing of changes in the magnitude of genetic and environmental influences on IQ as a function of...
