Impact of Maternal Vitamin D Receptor (VDR) Gene Polymorphisms on Spontaneous Preterm Birth (Egyptian Case-Control Study)

Diverse effects of Ba^(2+) and Co^(2+) on fura-2 fluorescence ratio signals (FR, F350/F380) were examined in cultured bovine aortic endothelial cells (BAECs). ATP (3 ?M) induced FR oscillations normal Ca^(2+)-containing solutions. Co^(2+), but not Ba^(2+), inhibited ATP-induced oscillations. In Ca^(2+)-free solutions, 3 ?M only elicited a single transient. When replaced Ca^(2+) the perfusate, provoked distinct The maximal rate rise signal was greater than seen without increased maintained to high steady level. external by transient oscillated with long recovery time constant. survey at excitation wavelength 350 nm (F350), decreased intensity presence Ca^(2+). however, F350 as well, especially results suggest that fluctuation is balanced release from internal stores influx Ba2+ seems be permeable through channels competes for dye. blocks does inhibit ATP-mediated cells.
