background: background and objectives: the biological variation of body mass index (bmi) and waist circumference (wc) with age may vary by gender. the objective of this study was to investigate the functional relationship of anthropometric measures with age and sex.methods: the data were collected from a population-based cross-sectional study of 1800 men and 1800 women aged 20-70 years in north...

the present study was carried out to compare different random regression models to estimate variance components of lamb's average birth weight per lambing (abwll) in mehraban sheep. the data were 5,559 abwll records of 2,244 mehraban ewes. the random regression models consisted of namely, flock-year-season of lambing as fixed effect, a fixed regression to fit average trajectory of the popu...

the present study used a constant level of citric acid and polyvinyl alcohol and different amounts of nanocrystalline cellulose (cnc) and tio2 nanoparticles to improve the properties of starch film. the effect of different amounts of glycerol was also examined. the results of differential scanning colorimetry demonstrated that the addition of cnc increased the melting and glass transition tempe...

We studied the influence of vitamin E on intramuscular collagen characteristics and on metacarpal growth plate evolution in suckling lambs. Twenty-four 5-d-old Ile de France suckling male lambs were divided into four equal weight groups, and weekly i.m. injections of DL-alpha-tocopheryl acetate (Control group, 0 IU; Group 1, 625 IU; Group 2, 1,000 IU; and Group 3, 1,500 IU) were given until the...

PURPOSE To investigate the effects of split-dose irradiation on primary and metastatic uveal melanoma cell lines, with a clonogenic survival assay. METHODS Appropriate cell concentrations of four primary and four metastatic human uveal melanoma cell lines were cultured for irradiation with single doses and with two equal fractions separated by 5 hours. After irradiation, colony formation was ...

PURPOSE Using current radiobiologic models and biologic parameters, we performed an exploratory study of the clinical consequences of hypofractionation in prostate cancer radiotherapy. METHODS AND MATERIALS Four hypofractionated treatment regimens were compared with standard fractionation of 2 Gy x 39 for prostate carcinoma using a representative set of anatomical structures. The linear-quadr...
