Adenosine 5'-cyclic diphosphoribose [cyclic ADP-ribose (cADPR)], a metabolite of NAD+ that promotes Ca2+ release from sea urchin egg homogenates and microsomal fractions, has been proposed to act as an endogenous agonist ...

Calcium channels derived from sarcoplasmic reticulum of frog skeletal muscle were fused with planar lipid bilayers. Fractional open times displayed two types of calcium dependence: (i) blockable channels showed a bell-shaped ...

Phosphorus is a crucial nutrient for the aquatic environment, however its excess has brought imbalance to the lake ecosystem. The mobile forms of phosphorus in the sediment are the available fractions that will be ...

The ophidic accidents attributed to the genus Micrurus sp., despite rare, are extremely severe and can led to death by respiratory arrest. The clinical manifestations of envenoming arise mainly from venom neurotoxic activity. ...

Application of recombinant human bone morphogenetic protein 2 (rhBMP-2) to implant surfaces has been of great interest due to its osteoinductive potential. However, the optimal coating methodology has not been clarified. ...
