Objective: Nowadays the value of bioelectrical impedance analysis (BIA) in the estimation of body adiposity both on a clinical basis in the individual and epidemiologically in large populations is of great interest. The current study determine accuracy of BIA compared with body mass index (BMI) measurement for estimating body composition in a group of normal weight employee women with a sedenta...
در بسیاری از آزمون هایی که ما انجام می دهیم ، برای رد یا تایید فرض صفر از p-value استفاده می کنیم . ما می توانیم در بسیاری از این آزمون ها به راحتی با چند آزمایش اولیه و تجربی ، برای پارامتر مورد علاقه ، یک کران بالا و یک کران پایین به دست آوریم اما با توجه به اینکه p-value تنها به مقدار مشخص شده و فرض صفر بستگی دارد ، نمی تواند به شایستگی از این اطلاعات برای گرفتن یک تصمیم بهتر و درستتر ، استف...
BACKGROUND Medical choices often evoke great value uncertainty, as patients face difficult, unfamiliar tradeoffs. Those seeking to aid such choices must be able to assess patients' ability to reduce that uncertainty, to reach stable, informed choices. OBJECTIVE The authors demonstrate a new method for evaluating how well people have articulated their preferences for difficult health decisions...
Although cross-sectional (between-person) comparisons consistently reveal age-related cognitive declines beginning in early adulthood, significant declines in longitudinal (within-person) comparisons are often not apparent until age 60 or later. The latter results have led to inferences that cognitive change does not begin until late middle age. However, because mean change reflects a mixture o...
The aim of this study is to investigate how elevation of body temperature changes organs blood flow during sevoflurane anesthesia. We conducted in vivo research on 14 male Wistar rats to monitor pulse rate and arterial blood pressure and measure hepatic, small intestinal, renal, and descending aortic blood flow using a laser Doppler blood flowmeter. We assessed the changes in organ blood flow, ...
thinking, impaired judgment, other disturbances of higher cortical function, or personality change. The disturbance is severe enough to interfere significantly with work or usual social activities or relationships with others. The diagnosis of Dementia is not made if these symptoms occur. . .in Delirium. . . The DSM-IIIR definition of dementia has good to very good reliability (kappa’s ranging ...
It is critical to discover why some people's cognitive abilities age better than others'. We applied multivariate growth curve models to data from a narrow-age cohort measured on a multi-domain IQ measure at age 11 years and a comprehensive battery of thirteen measures of visuospatial, memory, crystallized, and processing speed abilities at ages 70, 73, and 76 years (n = 1091 at age 70). We fou...
The present study used a coordinated analyses approach to examine the association of physical activity and cognitive change in four longitudinal studies. A series of multilevel growth models with physical activity included both as a fixed (between-person) and time-varying (within-person) predictor of four domains of cognitive function (reasoning, memory, fluency, and semantic knowledge) was use...
Hofmann, Asmundson, & Beck (2013--this issue) offer an overview of cognitive-behavior therapy (CBT) as well as its similarities and differences from so-called "third-generation" behavior therapies, particularly Acceptance and Commitment Therapy (ACT). In this commentary we suggest that CBT is most accurately viewed as a broad family of distinct psychotherapy models that includes the traditional...
