A large number of studies suggest that calcium triggers and accelerates vesicle endocytosis at many synapses and non-neuronal secretory cells. However, many studies show that prolonging the duration of the stimulation train, which induces more calcium influx, slows down endocytosis; and several studies suggest that instead of triggering endocytosis, calcium actually inhibits endocytosis. Here w...

The level of dental and oral hygiene on elementary school age children is very low, so it can be increasing the incidence of dental and oral diseases which caused by various microorganisms. Moutwash can keep dental and oral hygiene, but many commercial mouthwash is still used alcohol as their ingredients, which can be giving side effects, therefore, we still needed used alternative mouthwash, w...

Nature itself uses materials like cellulose to provide the structure of plants, chitin as the exoskeleton of several insects and molluscs, collagen for mechanical support in connective tissues and so on. At present, the socioeconomic situation of the modern world has raised the interest in renewable materials to use in regenerative medicine. The composition of Chitosan and/or Calcium Phosphates...

Inspired by Nature's catalyst, a nano-size layered manganese-calcium oxide showed a low overvoltage for water oxidation in acidic solutions, which is comparable to platinum.

A novel in vitro model based on a solution mainly composed of sodium, calcium, chloride and phosphate ions, was developed to study the calcification of biomaterials at near physiological conditions. This model, due to its ability to quickly calcify the tested materials, is called Accelerated Calcification Solution (ACS). PolyactiveTM 30170, PolyactiveTM 70/30 and its composites with nano-apatit...

in this paper, preparation, bioactivity, and osteoblast cell behavior of cortical bone derived nanobiphasic calcium phosphate (nano-bcp) are presented. the calcined bovine bone samples with the addition of di-ammonium hydrogen phosphate were heated at 700°c for 100 min, and thus nano-bcp with the composition of 63/37 hydroxyapatite (ha)/β-tricalcium phosphate (β-tcp) was produced. scanning elec...

Disturbance in water relations is the major causes of vase life reduction and senescence in cut flowers This problem is mainly due to microorganism proliferation in the vase solution which leads to vascular occlusion and reduction in solution uptake by cut flowers. Therefore a comprehensive study was conducted to evaluate the biocidal effect of nano silver particles (NSP) and compare it with so...
