A capillary zone electrophoresis (CZE) method with conductometric detection of biogenic amines (cadaverine, putrescine, agmatine, histamine, tryptamine and tyramine) is described. The optimised background electrolyte was the following: 15 mM histidine + 5 mM adipic acid + 1.5 mM sulphuric acid + 0.1 mM ethylenediaminotetraacetic acid + 0.1% hydroxyethylcellulose + 50% methanol. A clear separati...

The aim of this study was to evaluate the antimicrobial activity of Uncaria tomentosa (Willd.) DC (cat's claw) against Enterococcus faecalis, Staphylococcus aureus, and Candida albicans. Suspensions with 10(8) cells/ml of each microorganism were plated in triplicate on Mueller-Hinton agar. Wells in the agar were made and filled with 2% chlorhexidine (CHX) gel, 2% cat's claw (CC) gel, 2% CHX+CC,...

This paper reported the development of an alcohol sensor based on a glass substrate platform. The was coated with two nanomaterial types: Hydroxyethylcellulose/Polyvinylidene fluoride (HEC/PVDF) and Agarose Gel, for comparison purposes. Three layers coating material have been applied to obtain optimum sensing response. is kept dry 24 hours before expose variations ethanol concentration investig...

Contamination of maize and barley grain during storage by the toxigenic fungi Aspergillus flavus (A. flavus) Penicillium Verrucosum (P. verrucosum) is both an economic a public health problem, especially in less industrialized countries. Peracetic acid (PA) compound used for disinfection food contact surfaces. Unlike other disinfectants, it leaves no toxic residues its decomposition products (C...

The modern drug alaptide, synthetic dipeptide, shows regenerative effects and effects on the epitelisation process. A commercial product consisting of 1% alaptide hydrophilic cream is authorised for use in veterinary practice. This study focuses on the formulation of alaptide into semi-synthetic polymer-based hydrogels. The aim of the present study is to prepare hydrogels and to evaluate the li...

: Cosmetic formulators have numerous thickeners at their disposal to stabilize and increase the viscosity of formulations. Traditionally, some ingredients are most widely used for these purposes, such as polyvinylpyrrolidone, polyvinyl alcohol, sodium carboxymethylcellulose, hydroxyethylcellulose, hydroxypropylmethylcellulose, other cellulose derivatives, well carbomer acrylic acid derivatives ...
