Calcium intake and its relationship with risk of overweight and obesity in Adolescents
(2009-03-01)
Adolescents' eating habits are determined by social, psychological, economic, political, and educational influences. They tend to prefer foods with inadequate nutritional value and high fat and carbohydrate content which ...
Effect of calcium intake on urinary oxalate excretion in calcium stone-forming patients
(Associação Brasileira de Divulgação Científica, 2002-06-01)
Dietary calcium lowers the risk of nephrolithiasis due to a decreased absorption of dietary oxalate that is bound by intestinal calcium. The aim of the present study was to evaluate oxaluria in normocalciuric and hypercalciuric ...
Endocytic vesicles contain a calmodulin-activated Ca2+ pump that mediates the inhibition of acidification by calcium
(1990)
Endocytic vesicles isolated from rabbit reticulocytes contained an intrinsic Ca2+-pump activity that was dependent on ATP, activated by calmodulin and inhibited by vanadate. 45Ca2+ uptake and acidification studies indicated ...
Calcium-dependent halothane activation of sarcoplasmic reticulum calcium channels from frog skeletal muscle
(1994)
The effect of halothane on calcium channels present in sarcoplasmic reticulum membranes isolated from frog skeletal muscle was studied at the single channel level after fusing the isolated vesicles into planar lipid bilayers. ...
Regulation of Intercellular Calcium Signaling Through Calcium Interactions with Connexin-Based Channels
(2012)
The synchronization of numerous cellular events requires complex electric and metabolic cell-cell interactions. Connexins are a family of membrane proteins that constitute the molecular basis of two kinds of channels: gap ...
Signal transduction and gene expression regulated by calcium release from internal stores in excitable cells
(SOCIEDAD BIOLOGIA CHILE, 2004)
Calcium regulation of several transcription factors involves different calcium-dependent signaling cascades and engages cytoplasmic as well as nuclear calcium signals. The study of the specific sources of calcium signals ...
Influence of the addition of calcium hydroxide powder on some physical and chemical properties of the sealer MTA fillapex
(2012)
Objective: This study evaluated the flow, pH and calcium release of MTA Fillapex (G1) or Fillapex plus 10% in weight of calcium hydroxide powder (G2), compared to AH Plus (G3) and Sealapex (G4). Materials and methods:The ...
