A pilot study into the effect of whisky, wine and beer consumption on tooth surface dissolution.

Aim: To assess the potential of acute alcohol consumption to dissolve tooth surfaces and to evaluate the difference in the dissolution potential of whisky, beer and wine.

Methods: The study sample comprised 36 healthy male volunteers with mean age of 26.27 (SD-1.

Socio-behavioral variables effecting oral hygiene and periodontal status of 12 year-old schoolchildren of Udaipur district.

Aim: To assess the effect of various socio-demographic in addition to oral hygiene variables on the oral hygiene and periodontal status.

Methods: A combination of multi stage and cluster sampling procedure was followed to collect a representative population of 831, 12 year-old schoolchildren of Udiapur district. Oral Hygiene Index Simplified (OHI-S) and Community Periodontal Index (CPI) were used to evaluate oral hygiene and periodontal status respectively.

A study on drug-drug interaction of esomeprazole and anti-diabetic drugs.

Drug-drug interaction between esomeprazole at therapeutic and higher doses and sulfonylureas was studied. Sulfonylureas (tolbutamide 40 mg/kg and glibenclamide 40 µg/kg) were administered and the time to onset of hypoglycemia, the duration of the hypoglycemia, and the peak hypoglycemia were determined. Esomeprazole (1.

Antiulcer and Anti-inflammatory Activity of Aerial Parts Enicostemma littorale Blume.

The antiulcer and in vitro anti-inflammatory activities of the aerial parts of Enicostemma littorale against aspirin, ethanol, and pyloric ligation-induced ulcers in rats and bovine serum albumin denaturation were studied. The extract (200 mg/kg and 400 mg/kg po) was administered to the overnight fasted rats, one hour prior to aspirin / alcohol / pyloric ligation challenge. The ulcer index, tissue GSH levels, and lipid peroxidation levels were estimated in all the models of ulcers and the volume of gastric secretion, acidity, and pH, were estimated in the pyloric ligation model of ulcers.

Do active ingredients in non alcoholic chlorhexidine mouth wash provide added effectiveness? Observations from a randomized controlled trial.

Background And Objective: Chlorhexidine (CHX) is the most tested and leading oral antiseptic agent. Zinc as an active ingredient has shown additive and synergistic effect and when Sodium fluoride (NaF) was used it failed to show added effectiveness and the combined effect of NaF and Zinc chloride (ZnCl2) both as active ingredients has never been evaluated. The present study assessed the effectiveness of active ingredients and to compare the frequency of adverse events occurring with traditional CHX and CHX+NaF+ZnCl2.

Napin from Brassica juncea: thermodynamic and structural analysis of stability.

The napin from Brassica juncea, oriental mustard, is highly thermostable, proteolysis resistant and allergenic in nature. It consists of two subunits - one small (29 amino acid residues) and one large (86 amino acids residues) - held together by disulfide bonds. The thermal unfolding of napin has been followed by differential scanning calorimetry (DSC) and circular dichroism (CD) measurements.

Conformation of Napin (Brassica juncea) in salts and monohydric alcohols: contribution of electrostatic and hydrophobic interactions.

Napin from mustard (Brassica juncea L.) is a seed storage protein consisting of two subunits linked through disulfide bonds and is predominantly helical in nature. Resistance to trypsin digestion and allergenicity limit its food applications.

The contribution of ionic interactions to the conformational stability and function of polygalacturonase from A. niger.

Aspergillus niger produces multiple forms of polygalacturonases with molecular masses ranging from 30 to 60 kDa. The high molecular weight polygalacturonase (61+/-2 kDa) from A. niger possesses a pH optimum of 4.

A Lewis Acid Catalyst Anchored on Silica Grafted with Quaternary Alkylammonium Chloride Moieties.

Resistance to leaching and re-usability are characteristic of the novel heterogeneous Lewis acid catalyst that was prepared by anchoring tin(IV) chloride on silica grafted with tetraalkylammonium or pyridinium chloride groups. The catalyst displays high activity and selectivity in the synthesis of 3-methyl-3-buten-1-ol by the Prins condensation of isobutene with formaldehyde [Eq. (1)].
