BACKGROUND Testosterone in Older Men with Mobility Limitations Trial found an increased incidence of cardiovascular events in men randomized to testosterone, resulting in enrollment cessation by trial's Data and Safety Monitoring Board. We evaluated changes in gonadal hormones and markers of inflammation and coagulation to elucidate risk factors associated with cardiovascular events. METHODS ...

objectives: it is important to recognize any risk factors for the development of injuries in the athletic population. the aim of this study was to investigate the association between joint hyper mobility and low back pain in iranian hyper mobile and non-hyper mobile athletes. methods: 50 athletic patients with low back pain (age=23.20±12.79 years) and 51 healthy athletes (age=24.28±13.70) from ...

The low-temperature electron mobility is investigated here for electrons confined in modulation-doped In0.53Ga0.47As/InP single symmetric quantum wells. The subband structure calculation is developed via variational method, both Schrödinger and Poisson equations being solved simultaneously with adequate heterointerface matching conditions. With this in hands, the main electron scattering rates ...

The hole mobilities in the GaAs1-xSbx system is been investigated for 0.0 ≤ x ≤ 1.0. Undoped room temperature mobilities are used to examine the scattering as a function of the Sb content. Two scattering mechanisms are considered: ionised impurity and alloy scattering. The alloy scattering potential is found to be 1.868 eV, which is about twice the theoretical value. Samples of various doping l...

OBJECTIVE To test the hypothesis that aerobic-related leisure-time physical activity (PA) is associated with better cognitive function and that the effect varies among apolipoprotein E (APOE) genotype groups. DESIGN Cross-sectional study of persons examined in the Third National Health and Nutrition Examination Survey (NHANES-III; 1988-1994). SETTING US noninstitutionalized population. PA...
