Influence of ultrafiltration membrane characteristics on adsorptive fouling with dextrans [PDF]

open access: yes, 2005
This paper presents a detailed investigation of fouling mechanisms for ultrafiltration membranes with polysaccharides obtained by studying membrane–solute (static adsorption) and membrane–solute–solute interactions (ultrafiltration (UF)).

Mass transfer coefficients in cross-flow ultrafiltration [PDF]

open access: yes, 1989
Usually, in concentration polarization models, the mass transfer coefficient is an unknown parameter. Also, its variation with changing experimental circumstances is in question.

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

A novel function for the Caenorhabditis elegans torsin OOC-5 in nucleoporin localization and nuclear import. [PDF]

open access: yes, 2015
Torsin proteins are AAA+ ATPases that localize to the endoplasmic reticular/nuclear envelope (ER/NE) lumen. A mutation that markedly impairs torsinA function causes the CNS disorder DYT1 dystonia. Abnormalities of NE membranes have been linked to torsinA

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

Potential of novel dextran oligosaccharides as prebiotics for obesity management through in vitro experimentation [PDF]

open access: yes, 2014
The energy-salvaging capacity of the gut microbiota from dietary ingredients has been proposed as a contributing factor for the development of obesity. This knowledge generated interest in the use of non-digestible dietary ingredients such as prebiotics ...

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.

Release of macromolecules from albumin-heparin microspheres [PDF]

open access: yes, 1992
Hydrophilic microspheres based on albumin-heparin conjugates have been prepared as a macromolecular delivery system. The soluble albumin-heparin conjugate was synthesized and crosslinked in a water-in-oil emulsion with glutaraldehyde to form microspheres

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
