Nat Commun. 2020;11:4807. doi: 10.1038/s41467-020-18497-3.This interesting paper illustrates the potential of machine learning to improve the sensitivity and specificity of routine techniques in clinical practice if large cohorts for training and validation of models are used. Yu et al. present a transfer learning model (machine learning approach to solve research problems by r...

To read the full abstract: J Clin Endocrinol Metab, March 2020, 105(3):e70–e84A cohort of 21 adult males (aged 19 to 89 years) harboring hemizygous pathogenic IGSF1 gene mutations underwent anthropometry, endocrine testing, testis ultrasonography, and body composition assessment to define the pathophysiological role of IGSF1 in influencing GH secretion. In addition, two lines of Igsf1 -deficient male mice were use...

Abstract: Nature. 2019 Mar;567(7747):234–238.In brief: In this article, the authors present evidence that the murine epiphyseal growth plate develops a postnatal stem cell niche with monoclonal properties, that are able to self-renew. They thereby challenge the concept of a continous depletion of progenitor cells as a limiting factor for bone growth.<p class="abste...

Physical activity can reverse age-dependent decline in skeletal muscle, preventing osteopor...
