Dextran fouling of polyethersulfone ultrafiltration membranesâCauses, extent and consequences [PDF]

open access: yes, 2007
In a recent paper [Susanto, Ulbricht, J. Membr. Sci. 266 (2005) 132], we showed that dextran does foul polyethersulfone (PES) ultrafiltration (UF) membranes by contact of the solution with the membrane surface without flux through the membrane.

Dextran dextrinase and dextran of Gluconobacter oxydans

open access: yesJournal of Industrial Microbiology & Biotechnology, 2005
Certain strains of Gluconobacter oxydans have been known since the 1940s to produce the enzyme dextran dextrinase (DDase; EC2.4.1.2)-a transglucosidase converting maltodextrins into (oligo)dextran. The enzyme catalyses the transfer of an alpha1,4 linked glucosyl unit from a donor to an acceptor molecule, forming an alpha1,6 linkage: consecutive ...

Differential effects on membrane permeability and viability of human keratinocyte cells undergoing very low intensity megasonic fields [PDF]

open access: yes, 2017
Among different therapeutic applications of Ultrasound (US), transient membrane sonoporation (SP) - a temporary, non-lethal porosity, mechanically induced in cell membranes through US exposure - represents a compelling opportunity towards an efficient ...

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

A2A Adenosine Receptor Antagonism Reverts the Blood-Brain Barrier Dysfunction Induced by Sleep Restriction. [PDF]

open access: yesPLoS ONE, 2016
Chronic sleep restriction induces blood-brain barrier disruption and increases pro-inflammatory mediators in rodents. Those inflammatory mediators may modulate the blood-brain barrier and constitute a link between sleep loss and blood-brain barrier ...

Delivery of mixed-lineage kinase domain-like protein by vapor nanobubble photoporation induces necroptotic-like cell death in tumor cells [PDF]

open access: yes, 2019
Modern molecular medicine demands techniques to efficiently deliver molecules directly into mammalian cells. As proteins are the final mediators of most cellular pathways, efficient intracellular protein delivery techniques are highly desired.

Intrastriatal convection-enhanced delivery results in widespread perivascular distribution in a pre-clinical model

open access: yesFluids and Barriers of the CNS, 2012
Background Convection-enhanced delivery (CED), a direct method for drug delivery to the brain through intraparenchymal microcatheters, is a promising strategy for intracerebral pharmacological therapy.
