Amanda Devine, R Arthur Criddle, Ian M Dick, Deborah A Kerr, and Richard L Prince Abstract The influence of urinary sodium excretion and dietary calcium intake was examined in a 2-y longitudinal study of bone density in 124 women postmenopausal for > 10 y. Analysis of bone density changes showed that urinary sodium excretion was […]

Anand Vaidya, MD MMSc, Jenifer M. Brown, MD, and Jonathan S. Williams, MD MMSc Abstract There is increasing evidence of a clinically relevant interplay between the renin-angiotensin-aldosterone system and calcium regulatory systems. Classically, the former is considered a key regulator of sodium and volume homeostasis while the latter is most often associated with skeletal health. […]
Rebecca A. Capel and Derek A. Terrar* British Heart Foundation Centre of Research Excellence, Department of Pharmacology, University of Oxford, Oxford, UK Mechanisms underlying pacemaker activity in the sinus node remain controversial, with some ascribing a dominant role to timing events in the surface membrane (“membrane clock”) and others to uptake and release of […]

Alice H. Tischler, Louise Lie, Cecilia M. Thompson, Karen L. Visick George O’Toole, Editor ABSTRACT Vibrio fischeri uses biofilm formation to promote symbiotic colonization of its squid host, Euprymna scolopes. Control over biofilm formation is exerted at the level of transcription of the symbiosis polysaccharide (syp) locus by a complex set of two-component regulators. Biofilm formation can be induced […]
Viruses originate from RNAs. The sugar in RNA is ribose sugar and is the phosphates based, and they react in the nucleotides to form an ester bond. While not inside a cell or in the process of cell infection, viruses exist as an independent particle known as virions or virus particles. The way the virus […]
Nutrients 2013, 5, 3964-3974; doi:10.3390 / nu5103964 / ISSN 2072-6643 Abstract: Concern has recently arisen about the potential adverse effects of excessive calcium intakes, i.e., calcium loading from supplements, on arterial calcification and risks of cardiovascular diseases (CVD) in older adults. Published reports that high calcium intakes in free-living adults have relatively little or […]
