Exploring the physicochemical and antimicrobial properties of gold-chitosan hybrid nanoparticles composed of varying chitosan amounts.

A green synthesis method for gold-chitosan hybrid nanoparticles (Au-CS hNPs) using different concentrations of CS as a capping/reducing agent is reported to investigate the effect of CS concentration on the physicochemical properties as well as the antimicrobial activity of the developed Au-CS hNPs. The as-synthesized Au-CS hNPs were characterized using visible spectrophotometry, FTIR, dynamic light scattering, DSC, XRD, SEM-EDX and TEM. The size of the formed hNPs ranges from 16.

Density and refractive index data of binary and ternary mixtures of imidazolium-based ionic liquids, -hexane and organic compounds involved in the kinetic resolution of rac-2-pentanol.

This data article is related to the subject of the research article "Extraction of Organic Compounds Involved in the Kinetic Resolution of rac-2-Pentanol from n-Hexane by Imidazolium-based Ionic Liquids: Liquid-Liquid Equilibrium" (Montalbán et al., 2018) [1]. It contains experimental data of density and refractive index of binary and ternary mixtures of imidazolium-based ionic liquids, -hexane and organic compounds involved in the kinetic resolution of -2-pentanol (-2-pentanol, vinyl butyrate, -2-pentyl butyrate or butyric acid) measured at 303.

Influence of ionic strength on the flexibility of alginate studied by size exclusion chromatography.

SEC measurements of the [η]-M relationship for alginate from Macrocystis pyrifera and the wormlike model can be used to characterize flexibility through two independent treatments (Bohdanecky's equations and HYDFIT program), both providing the same results. Two different assumptions concerning mass per unit of length lead to different conclusions. First: persistence length decreases with ionic strength (the intrinsic component of the persistence length is 11.

Peginterferon alpha-2a and ribavirin in patients with hepatitis C virus genotype 1 infection with persistently normal alanine aminotransferase levels.

Background And Aim: To evaluate the efficacy and safety of peginterferon α-2a plus ribavirin at standard doses in patients with hepatitis C virus (HVC) genotype 1 infection with persistently normal alanine aminotransferase (ALT) levels.

Methods: Patients aged 18 to 65 years were included in this observational, prospective study if they had evidence of a HCV genotype 1 infection. The serum HCV RNA concentration was determined at baseline and week 12.

[Emergency care of patients with upper gastrointestinal bleeding in regional hospitals in Catalonia].

Objective: To evaluate the resources available in Catalan regional hospitals for the emergency care of upper gastrointestinal hemorrhage.

Methods: We analyzed a survey sent to 32 hospitals on the availability, composition and resources of a duty endoscopy service for the year 2009.

Results: Responses were obtained from 24 centers, covering 3,954,000 inhabitants.
