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 ...

Sizing nanomaterials in bio-fluids by cFRAP enables protein aggregation measurements and diagnosis of bio-barrier permeability [PDF]

open access: yes, 2016
Sizing nanomaterials in complex biological fluids, such as blood, remains a great challenge in spite of its importance for a wide range of biomedical applications. In drug delivery, for instance, it is essential that aggregation of protein-based drugs is

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.

Uptake of macromolecules by cercariae during skin penetration and transformation to schistosomula (Schistosoma mansoni) [PDF]

open access: yes, 2010
Here, we observed the uptake of membrane-impermeant molecules by cercariae as they penetrate the skin and are transformed into schistosomula. We propose that membrane-impermeant molecules, Lucifer Yellow, Propidium iodide and Hoechst 33258 enter the ...

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.

Dextran-enhanced CEST MRI reveals the size effect of BBB dysfunction associated with neuroinflammation

open access: yesVeins and Lymphatics, 2022
INTRODUCTION: The blood-brain barrier (BBB) is compromised in multiple central nervous system (CNS) disorders associated with neuroinflammation, including multiple sclerosis (MS).

Calibration of ultrafiltration membranes against size exclusion chromatography columns [PDF]

open access: yes, 2010
Using the extension of the concept of universal calibration parameter, yielding a relation between the hydrodynamic volume of molecules and the elution volume in sizeexclusionchromatography (SEC), to retention coefficients in ultrafiltration (UF), we ...

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 ...

Dextranas em açúcares do estado de São Paulo Dextrans in lugars from São Paulo State

open access: yesQuímica Nova, 2008
The characterization of dextran in sugars by size exclusion chromatography (SEC) has been carried out according to the number-average molecular weight (Mn), the weight-average molecular weight (Mw), the Z-average molecular weight (Mz), and the ...

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 ...
