background: patients suffering from major beta thalassemia need frequent blood transfusions and, if not treated well, would be at risk of heart dysfunction. this study was performed to determine the diagnostic value of electrocardiography versus echocardiography in measuring the left ventricular mass index in these patients. methods: between july 2010 and june 2011, 82 asymptomatic patients ove...

background: the aim was to investigate the relationships among lean mass (lm), fat mass (fm), and bone mineral density (bmd) in women stratified by body mass index (bmi) (bmi – normal-weight, overweight, obese) and to determine threshold at which body fat assumes negative relationship with bmd. methods: this was a cross-sectional study in 471 healthy caucasian women, aged 18-67 years. bmd, lm, ...

background: the sensitivity and specificity of body mass index (bmi) percentiles of centers for disease control 2000 (cdc2000) standard was compared with child actual overweight which was identified by fat mass index (fmi) and overweight status in these children based on bmi and fmi. methods: in this case-control study, elementary school girls (aged 8-10 years) were recruited from schools of is...

We have carried out a series of small scale collisional N-body calculations of single-mass star clusters to investigate the dependence of the lifetime of star clusters on their initial parameters. Our models move through an external galaxy potential with a logarithmic density profile and they are limited by a cut-off radius. In order to find scaling relations between the lifetime of star cluste...
