Why is calcium chloride basic/alkaline, with a pH of 8-9? « on: September 20, 2009, 11:49:37 PM » A variety of sources, including Wikipedia and several chemistry websites, stated (without explanation) that the pH of both anhydrous and hydrated calcium chloride, are basic/alkaline.B...
Apolipoprotein E4 (APOE4) is the strongest known genetic risk factor for late-onset Alzheimer’s disease (AD). Conditions of stress or injury induce APOE expression within neurons, but the role of neuronal APOE4 in AD pathogenesis is still unclear. Here
A cofactor is a chemical compound that is required for certainenzymes— called conjugated enzymes — to become active. Vitamins andmineralsserve as the cofactors required by the human body to function properly. These nutrients may either be cofactors themselves or may be chemically modified to become...
To perform immunohistological analysis of the bone marrow, harvested femurs were fixed overnight in 4% (v/v) PFA, decalcified for two days in PBS, pH 7.4, 10% (w/v) EDTA and finally fixed in optimum cutting temperature compound (OCT; CellPath) following an overnight incubation in 20% ...
Magnesium oxide (MgO) is an important inorganic compound widely used in various industries and scientific research. It is composed of magnesium (Mg) ..
with a mixture of bothbilRversions being seen. The short variant of thebilRgene is monophyletic (clade 2 in Fig.4a), suggesting that there has been extensive horizontal gene transfer during the evolution ofbilR, particularly in Firmicutes. SomebilRgenes were found in bacteria from the Flavoba...
27. Chorda tympani nerve responses to NH4Cl in theSkn-1a−/−mice were robust and not significantly different from responses observed in wild-type mice (Fig.1a, b). Responses to the sweet compound AceK were strongly attenuated inSkn-1a−/−compared with wild-type mice, as previously...
