Calcium Signalling calcium signaling molecules
2017/3/7
Applications for this meeting must be submitted by May 20, 2017. Please apply early, as some meetings become oversubscribed (full) before this deadline. If the meeting is oversubscribed, it will be st...
The influence of genetic susceptibility and calcium plus vitamin D supplementation on fracture risk
fracture bone mineral density genetic risk score calcium vitamin D postmenopausal women
2018/11/13
Background: Fracture is a complex trait, affected by both genetic and environmental factors. A meta-analysis of genome-wide association studies (GWASs) identified multiple bone mineral density (BMD) a...
Effects of calcium supplementation on body weight: a meta-analysis
body weight calcium meta-analysis obesity body mass index
2018/12/18
Background: Whether calcium supplementation can reduce body weight and prevent obesity remains unclear because of inconsistent reports.

Effects of protein kinase C on parthenogenetic activation of pig oocytes using calcium ionophore or nitric oxide-donor
oocyte pig parthenogenesis activation calcium ionophore nitric oxide
2015/6/4
Porcine oocytes matured in vitro were activated for parthenogenetic development using either calcium ionophore (50μM for 10 min) or nitric oxide donor SNAP (2mM for 23.5 hours). Protein kinase C (PKC)...
The Pyrethroid Deltamethrin, Which Causes Choreoathetosis with Salivation (CS-Syndrome), Enhances Calcium Ion Influx via Phosphorylated CaV2.2 expresssed in Xenopus laevis oocytes
deltamethrin CaV2.2 PMA
