Parathyroid hormone (PTH) secretion maintains extracellular calcium (Ca2+o) homeostasis under the control of the calcium-sensing receptor (CaR). Supra-physiological pHo changes (±1 pH unit) significantly alter CaR activity in a heterologous expression system. Interestingly, metabolic acidosis and hyperparathyroidism are concomitant in both ageing and chronic kidney disease. Therefore, here we examined whether smaller, pathophysiological pH...

Exposure to soy isoflavones (ISO), abundant in soy protein infant formula, during early postnatal life has benefits to bone health in female mice. Moreover, exposure during the first 10 or 21 days of life has been shown to interfere with structural development of female reproductive organs and results in heavier body weight. The study objective was to compare if shorter exposure to ISO, during the first 5 vs 10 days of life, results in lesser adverse effects on ovarian and ute...

Ageing is associated with sarcopenia, osteoporosis and an increased risk of falling, which together contribute to increased fracture risk. There are few data describing the associations between functional measures of muscle and bone during ageing. Therefore, the aim of this study was to examine in ageing men associations between measures of lower-limb muscle strength and age and then to investigate the relationships with tibial bone outcomes.Men (n</...
