Using complementary physical-chemical methods including turbidimetry, quasielastic light scattering, gel filtration, and phase analysis, we examined the interactions between dilute concentrations of the common bile salt, taurochenodeoxycholate (TCDC), and uni- and multilamellar vesicles (MLVs) composed of defined molecular species of lecithin (L) and varying contents of cholesterol (Ch). Dissol...

Diabetes Mellitus (DM) is a metabolic disease caused by high blood glucose levels (hyperglycemia). Hyperglycemia due to lack of insulin secretion in the body. Glycemic control diabetic patients seen HbA1C levels. One complications DM nephropathy. Renal function abnormalities associated with nephropathy are indicated increased creatinine and microalbumin. This shows that it necessary monitor kid...

Throughfall deposition was measured in a complex ecosystem at the southeast of Mexico. Samples were collected in an annual basis at Xicalango-Atasta region in Campeche State. Ionic exchange resin collectors were used in 13 points in a multiple transects design. Ions retained were extracted and analyzed by colorimetry and turbidimetry. Mean throughfall deposition fluxes for N and S were 0.97 and...

The present study investigated the in vitro effect of lysozyme (0-1,000 µg/ml) on Candida albicans (C. albicans) biofilm development. Investigations were conducted on C. albicans ATCC 10231 and on 10 clinical isolates from dentures. Strains were cultured aerobically at 37˚C in Sabouraud broth. Yeast growth was evaluated by turbidimetry. Biofilm biomass was quantified on a polystyrene support by...

A new method combining automatic turbidimetry and sequential viable count determinations was developed to evaluate the in vitro activity of various antifungal agents alone and in combination against three clinical isolates of Candida spp. (two Candida albicans and one C. tropicalis) at two inocula (10(-5) and 10(-6) CFU/ml). Specific parameters were derived from the time-kill curves: the maxima...

Cement paste is an already well-known material used in ore mining. It mainly to fill excavation areas and the tailings from surface return underground mines. In this way, amount of deposited degradation terrain are reduced. The itself can be as artificial barrier between mining works watercourses. Significant economic environmental benefits expected using cement paste, which would contribute su...

quercetin, a ubiquitous flavonol, represents a promising leading drug for development of new chemotherapeutic agents. however, its limited cytotoxicity to cancer cells hampers its clinical use. in order to obtain novel quercetin derivatives with superior cytotoxicity, seven alkylated quercetin derivatives were synthesized. solubility of these derivatives was determined by turbidimetry. cytotoxi...
