BACKGROUND Seasonal variation and regional heterogeneity have been observed in the estimated effect of fine particulate matter (PM2.5) mass on mortality. Differences in the chemical compositions of PM2.5 may cause this variation. We investigated the association of the daily concentration of PM2.5 components with mortality in Nagoya, Japan. METHODS We combined daily mortality counts for all re...

Globally, there is growing demand in natural colourants from plants the food, cosmeceutical and pharmaceutical fields. Generally, among various categories of secondary metabolites, carotenoids, anthocyanins, phenols are significant plant-based pigments. Coloured pigments possess remarkable anthocyanin related to anti-oxidant, anti-inflammatory anti-metastatic features. The major objective this ...

Potassium monopersulfate has been decomposed in aqueous solution in the presence of Co(II). The process has been simulated by means of a mechanism based on elementary reactions. Rate constants have been taken from literature reports or, alternatively, assimilated to analogous reactions occurring in Fenton ́s chemistry. Several operating conditions have been successfully applied. Keywords—Monoper...

A technique for the isolation of ribonucleic acid (RNA)-rich mutants of Escherichia coli is described. Mutagenized cells were centrifuged to isopycnic equilibrium on potassium tartrate or cesium sulfate gradients. Samples from the region of the gradients slightly denser than the majority of the cells were spread on agar plates, and the resulting clones were tested for increased RNA to protein r...

A quick hemostatic effect, as well as sclerosing and shrinkage of hemorrhoids, can be attained when internal hemorrhoids are treated by using injection therapy with aluminum potassium sulfate and tannic acid (ALTA), the outcomes of treatment may be similar to those of a hemorrhoidectomy. However, if the type of hemorrhoid or the method of injection is not appropriate for ALTA treatment, complic...

Recent reports have implicated the NLRP3-associated inflammasome in the adjuvanticity of alum. Here, we summarize the major findings and ask what this may mean for improving human vaccination.

BACKGROUND Dalfampridine (4-aminopyridine; 4-AP) is a potassium channel blocker that has been available in the United States as a treatment to improve walking in patients with multiple sclerosis. 4-AP is well-characterized in vitro with regard to inhibition of neuronal potassium channels, but the potential contribution of its metabolites to clinical activity has not been determined. This study ...

drought stress is one of the most important problems of agriculture and an important factor of plant product reduction. application of absorbent materials can help usage of sporadic rain fall and cause more maintenance of water storage. in order to study the effect of super absorbent polymer, potassium sulfate and manure under drought condition and favorable irrigation on some traits of foxtail...

T, .ranscorneal potentials have been reported by several laboratories and have been related to an active transfer of sodium ions across the cornea. Both epithelial and endothelial cells have been implicated as sites of a metabolic pump. The active transport of ions across the cornea is involved in the maintenance of hydration, thickness, and transparency." The effect of these ions may be indire...
