A systematic approach to study the pH-dependent release, productivity and product specificity of dextransucrases

open access: yesMicrobial Cell Factories, 2019
Background Dextransucrases are extracellular enzymes, which catalyze the formation of α-1→6-linked glucose polymers from sucrose. These enzymes are exclusively expressed by lactic acid bacteria, which commonly acidify the extracellular environment due to

Development and optimization of a novel sustained-release dextran tablet formulation for propranolol hydrochloride [PDF]

open access: yes, 2006
A novel oral controlled delivery system for propranolol hydrochloride (PPL) was developed and optimized. The in vitro dissolution profiles of sustained-release matrix tablets of racemic PPL were determined and compared with the United States Pharmacopeia

Formation of nanoparticles by cooperative inclusion between (S)-camptothecin-modified dextrans and β-cyclodextrin polymers

open access: yesBeilstein Journal of Organic Chemistry, 2015
Novel (S)-camptothecin–dextran polymers were obtained by “click” grafting of azide-modified (S)-camptothecin and alkyne-modified dextrans. Two series based on 10 kDa and 70 kDa dextrans were prepared with a degree of substitution of (S)-camptothecin ...

Aqueous Angiography: Real-Time and Physiologic Aqueous Humor Outflow Imaging. [PDF]

open access: yesPLoS ONE, 2016
PURPOSE:Trabecular meshwork (TM) bypass surgeries attempt to enhance aqueous humor outflow (AHO) to lower intraocular pressure (IOP). While TM bypass results are promising, inconsistent success is seen.

Formation of Microcages from a Collagen Mimetic Peptide via Metal-Ligand Interactions

open access: yesMolecules, 2021
Here, the hierarchical assembly of a collagen mimetic peptide (CMP) displaying four bipyridine moieties is described. The CMP was capable of forming triple helices followed by self-assembly into disks and domes.

Improvement of a method for the characterization of ultrafiltration membranes by measurements of tracers retention [PDF]

open access: yes, 2004
The aim of this study is to improve protocols for assessing accurate characteristic retention curve and cut-off of membranes, thus enabling the manufacture and performance of the membrane to be monitored. Different data treatments are considered in order

Evaluation of free radical‐induced structural changes and their effect on antioxidant and anti‐inflammatory activities of UV/H2O2‐degraded dextrans

open access: yeseFood
Although ultraviolet (UV)/H2O2 treatment could effectively improve the bioactivities of polysaccharides, the relationship between free radical‐induced structural changes and the bioactivities of products remains unknown. Therefore, this work investigated
