Age- and Sex-Related Volumetric Density Differences in Trabecular and Cortical Bone of the Proximal Femur in Healthy Population.

Background: There are age- and sex-related increases in the prevalence of osteoporosis. Bone densitometry based on dual energy X-ray absorptiometry (DXA) is the gold standard for the assessment of bone mineral density (BMD). Three-dimensional (3D) analysis of the proximal femur (3D-DXA) allows discrimination between cortical and trabecular compartments, and it has shown a good correlation with computed tomography.

Mitochondrial genome of Neuryurus rudis (Xenarthra, Cingulata); contribution to phylogeny and origin of glyptodonts.

The remarkable glyptodonts have sparked the interest of evolutionary biologists since the 19th century, in their attempts to elucidate the phylogenetic relationships among the various species of these armored giants and their relationship with other xenarthrans. In recent years, the molecular analysis of the first glyptodont has included them within the cingulates, as a special group of armadillos that lost the mobility of the bands of their armor during their evolutionary history. In this research, we obtained the mitochondrial DNA sequence of the elusive and poorly known glyptodont Neuryurus rudis, inferring its phylogenetic position with respect to the glyptodont Doedicurus sp.

Global self-esteem and degree of overweight/obesity: are they linked in the adult population? A systematic review and meta-analysis.

Objective: Self-esteem may be adversely affected in adults with overweight or obesity, particularly women and those showing higher BMIs, although there is no consensus in the literature. The objective of the current study, based on reported cross-sectional associations, was to clarify the relationship between global self-esteem and overweight/obesity in adults.

Methods: Four databases were searched to identify eligible literature published prior to June 2024, and a systematic review was conducted of the 120 articles identified.

Joint kinematic responses of Olympic medallist skiers to repeated slalom runs.

This case study aims to examine changes in the lower limb joint kinematic profile and performance stability induced by repeated ski runs in two world-class alpine skiers. Two Olympic medallist alpine skiers were tested during their slalom training, with continuous recording of right knee and hip angles, along with turn time and run time. The eight runs of the training session were analysed with linear mixed models.
