Analysis of In Vitro Cytotoxicity of Carbohydrate-Based Materials Used for Dissolvable Microneedle Arrays.

Numai utilizatorii înregistrați pot traduce articole

Dissolvable microneedle arrays (MNAs) can be used to realize enhanced transdermal and intradermal drug delivery. Dissolvable MNAs are fabricated from biocompatible and water-soluble base polymers, and the biocargo to be delivered is integrated with the base polymer when forming the

Retardation of thermal and urea induced inactivation of alpha-chymotrypsin by modification with carbohydrate polymers.

Numai utilizatorii înregistrați pot traduce articole

Modification of enzymes by means of covalent coupling using soluble polymers results in enzymes which retain high biological activity and display resistance to denaturants, high temperature and chaotropic agents. Alpha-chymotrypsin, which has a potential for use in industrial applications, was

Differentiation of carbohydrate gums and mixtures using fourier transform infrared spectroscopy and chemometrics.

Numai utilizatorii înregistrați pot traduce articole

Guar gum, a nonionic galactomannan, is used as an economical thickener and stabilizer in the food industry and is often combined with xanthan, locust bean gum (LBG), or carboxymethylcellulose (CMC) to promote synergistic changes in viscosity or gelling behavior via intermolecular interactions;

Hydrophobically Modified Glucan as an Amphiphilic Carbohydrate Polymer for Micellar Delivery of Myricetin.

Numai utilizatorii înregistrați pot traduce articole

Myricetin (Myr) is a phytochemical with many functional properties. However, its hydrophobicity, low bioavailability, and stability limit its application. In this study, octadecanoate oat β-glucan (OGE) was synthesized and gained recognition as a self-assembled micelle forming a polymer with a

Novel multifunctional colloidal carbohydrate nanofiber electrolytes with excellent conductivity and responses to bone cancer cells.

This work presents a new approach to fabricating novel polymer nanofiber composites (NFCs) from water solution blends of PVA (hydrolyzed 89%)/ODA-MMT and Na-CMC/ODA-MMT nanocomposites as well as their folic acid (FA) incorporated modifications (NC-3-FA and NC-4-FA) through green electrospinning

Comparison of Five Extraction Methods for Intracellular Metabolites of Salmonella typhimurium.

Numai utilizatorii înregistrați pot traduce articole

Salmonella enterica serovar typhimurium (S. typhimurium) causes food poisoning in human and animals. Its infection rate is the highest among all salmonella serotypes. Metabolomics is a potential way to study the pathogenesis of S. typhimurium via analysis of various small molecular substances. Due

Isolation and Characterization of the First Xylanolytic Hyperthermophilic Euryarchaeon Thermococcus sp. Strain 2319x1 and Its Unusual Multidomain Glycosidase.

Numai utilizatorii înregistrați pot traduce articole

Enzymes from (hyper)thermophiles "Thermozymes" offer a great potential for biotechnological applications. Thermophilic adaptation does not only provide stability toward high temperature but is also often accompanied by a higher resistance to other harsh physicochemical conditions, which are also

Complexation of alkyl glycosides with α-cyclodextrin can have drastically different effects on their conversion by glycoside hydrolases.

Numai utilizatorii înregistrați pot traduce articole

Substrates present in aggregated forms, such as micelles, are often poorly converted by enzymes. Alkyl glycosides constitute typical examples and the critical micelle concentration (CMC) decreases with increasing length of the alkyl group. In this study, possibilities to hydrolyse alkyl glycosides

Subchronic oral toxicity study with regular and enzymatically depolymerized sodium carboxymethylcellulose in rats.

Numai utilizatorii înregistrați pot traduce articole

Enzymatically depolymerized sodium carboxymethylcellulose (CMC-ENZ) is a new functional food ingredient which has a lower molecular weight and viscosity than regular sodium carboxymethylcellulose (CMC). Both compounds are known not to be absorbed to a significant extent, and the human safety of CMC

Directed evolution of the bacterial endo-β-1,4-glucanase from Streptomyces sp. G12 towards improved catalysts for lignocellulose conversion.

Numai utilizatorii înregistrați pot traduce articole

With the aim to develop biocatalysts for enhanced hydrolysis of (hemi)cellulose into monosaccharides, random diversity by directed evolution was introduced in the gene coding for the endo-β-1,4-glucanase from Streptomyces sp. G12 which had been recombinantly expressed in Escherichia coli and named

Discovery and characterization of a thermostable two-domain GH6 endoglucanase from a compost metagenome.

Numai utilizatorii înregistrați pot traduce articole

Enzymatic depolymerization of recalcitrant polysaccharides plays a key role in accessing the renewable energy stored within lignocellulosic biomass, and natural biodiversities may be explored to discover microbial enzymes that have evolved to conquer this task in various environments. Here, a

A monoclonal antibody with binding and inhibiting activity towards human pancreatic carcinoma cells. I. Immunohistological and immunochemical characterization of a murine monoclonal antibody selecting for well differentiated adenocarcinomas of the pancreas.

Numai utilizatorii înregistrați pot traduce articole

The murine monoclonal antibody (MAb) BW 494 was characterized in relation to its tissue specificity, the epitope recognized, in vitro and in vivo radiolocalization and its potential to mediate antibody dependent cellular cytotoxicity (ADCC) and complement mediated cytolysis (CMC). The MAb defined

Differential Proteomic Profiles of Pleurotus ostreatus in Response to Lignocellulosic Components Provide Insights into Divergent Adaptive Mechanisms.

Numai utilizatorii înregistrați pot traduce articole

Pleurotus ostreatus is a white rot fungus that grows on lignocellulosic biomass by metabolizing the main constituents. Extracellular enzymes play a key role in this process. During the hydrolysis of lignocellulose, potentially toxic molecules are released from lignin, and the molecules are derived

Effects of cellulose, carboxymethylcellulose and inulin fed to rats as single supplements or in combinations on their caecal parameters.

Numai utilizatorii înregistrați pot traduce articole

We compared the effect of diets containing different nondigestible carbohydrates: cellulose (C), inulin (IN) and carboxymethylcellulose (CMC) as single supplements or in dietary combination on caecal physiology of rats. Sixty male Wistar rats (Rattus norvegicus) were divided into five groups and for

Surrogate target cells expressing surface anti-idiotype antibody for the clinical evaluation of an internalizing CD22-specific antibody.
