Alginate is a linear anionic heteropolysaccharide with chemical structure consisting of 1,4-linked subunits β-D-mannuronic acid (M) and its C-5 epimer α-L-guluronic (G). It well known that the monomer composition molecular weight alginates affect their properties influence use in food pharmaceutical industries. usually extracted from seaweed for commercial purposes, but can also be produced by ...

OBJECTIVE To identify whether women with poor ovarian response may benefit from treatment with corifollitropin alfa in a GnRH antagonist protocol. DESIGN Retrospective pilot study. SETTING University-based tertiary care center. PATIENT(S) Poor ovarian responders fulfilling the Bologna criteria developed by European Society for Human Reproduction and Embryology Consensus Group. INTERVENT...

Alginate oligosaccharides (AOS), belonging to the class of functional marine oligosaccharides, are low-molecular polymers linked by ?-1,4-mannuronic acid (M) and ?-1,4-guluronic (G), which could be classically obtained enzymatic hydrolysis alginate. With low viscosity good water solubility, as well anti-oxidant, immune regulation, anti-bacterial anti-inflammatory activities, AOS have been widel...

Background and Objective: To assess the control release of bio-molluscicides (Crude Ferula asafoetida and their active component ferulic acid) loaded in alginates as binding matrix. Methodology: Sodium alginate, an anionic block copolymer of β-D-mannuronic acid and α-L-guluronic acid, is a readily available, non-toxic polysaccharide its property to form gel with divalent and multivalent cations...

The influence of abscisic acid (ABA) on carbon metabolism, rate of photorespiration, and the activity of the photorespiratory enzymes ribulose bisphosphate oxygenase and glycolate oxidase in 7-day-old barley seedlings (Hordeum vulgare L. var. Alfa) was investigated. Plants treated with ABA had enhanced incorporation of labeled carbon from (14)CO(2) into glycolic acid, glycine, and serine, while...

The distinct molecular structure of darbepoetin alfa, in both its amino acid sequence and its carbohydrate content, results in a biologic profile with lower binding affinity, longer circulating half-life, and higher in vivo potency compared with the epoetins. The mechanisms responsible for these differences in biological effects have not been fully explained. Pharmacokinetic investigations of d...

INTRODUCTION Treatment of chronic hepatitis C (CHC) with pegylated interferon (Peg-IFN) and ribavirin leads to sustained virological response (SVR) in approximately 50% of the patients. SVR depends on hepatitis C virus (HCV) and host factors, including IL28B genotypes. OBJECTIVES The aim of the study was to investigate the therapeutic efficacy of the difficult-to-treat HCV genotype 1b in pati...

BACKGROUND & AIMS Lysosomal acid lipase deficiency is an autosomal recessive enzyme deficiency resulting in lysosomal accumulation of cholesteryl esters and triglycerides. LAL-CL04, an ongoing extension study, investigates the long-term effects of sebelipase alfa, a recombinant human lysosomal acid lipase. METHODS Sebelipase alfa (1mg/kg or 3mg/kg) was infused every-other-week to eligible sub...

The enzymes mannuronan C-5 epimerases catalyse the in-chain epimerisation of beta-D-mannuronic acid to alpha-L-guluronic acid in the last step of alginate biosynthesis. The recombinant C-5 epimerase AlgE4, encoded by the soil bacteria Azotobacter vinelandii and expressed in Escherichia coli, exhibits a non-random mode of action when acting on mannuronan and alginates of various monomeric compos...
