BACKGROUND AND PURPOSE Normative age-related decline in paravertebral muscle quality is important for reference to disease and risk identification in patients. We aimed to establish age- and vertebral level-dependence of paravertebral (multifidus and erector spinae) muscle volume and fat content in healthy adult volunteers. MATERIALS AND METHODS In this prospective study multifidus and erecto...

PURPOSE To investigate the association between subfoveal choroidal thickness and ocular axial length, refractive error, and blood pressure in healthy young women and men. METHODS Cross-sectional observational study of 93 eyes in 93 healthy Danish university students (mean age 24.9 ± 2.6 years). The submacular choroid was imaged using enhanced-depth imaging spectral domain optical coherence to...

The results of several studies have shown that homosexual men have an increased prevalence of non-right-handedness and atypical patterns of hemispheric functional asymmetry. Non-right-handedness in men has been associated with increased size of the corpus callosum (CC), particularly of the isthmus, which is the posterior region of the callosal body connecting parietotemporal cortical regions. W...
