Effects of dextran and dextran sulfate on the glucoamylase-catalyzed reaction.

open access: yesAgricultural and Biological Chemistry, 1977
The hydrolysis of maltose by glucoamylase (EC 3. 2. 1. 3 from Rhizopus niveus) was carried out in the presence and absence of dextran and dextran sulfate, which are the components of supports of immobilized enzymes. The interaction between dextran and the enzyme was observed by the fluorescence spectrophotometry.

Blood-brain barrier disruption in CCL2 transgenic mice during pertussis toxin-induced brain inflammation [PDF]

open access: yes, 2012
BACKGROUND: The chemokine CCL2 has an important role in the recruitment of inflammatory cells into the central nervous system (CNS). A transgenic mouse model that overexpresses CCL2 in the CNS shows an accumulation of leukocytes within the perivascular ...

Embedded 3D‐Coaxial Bioprinting of Stenotic Brain Vessels with a Mechanically Enhanced Extracellular Matrix Bioink for Investigating Hemodynamic Force‐Induced Endothelial Responses

open access: yesAdvanced Functional Materials, EarlyView.
In this study, a physically enhanced vascular dECM bioink and used 3D‐coaxial bioprinting are developed to fabricate mature brain blood vessels for cerebral atherosclerosis research. This model demonstrates that vascular geometry‐induced hemodynamic changes trigger vascular inflammation, ensuring its potential for cerebrovascular research.

Perfusable Brain Microvascular Network‐On‐Chip Model to Study Flavivirus NS1‐Induced Endothelial Dysfunction

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a microfluidic brain microvascular network‐on‐chip (BMVasChip) to investigate endothelial barrier dysfunction caused by flavivirus non‐structural protein 1 (NS1), including virus‐ and time‐dependent vascular damage, leakiness, and dysfunction.

Chromatographic Separation of Isomaltooligosaccharides on Ion-Exchange Resins: Effect of the Cationic Form

open access: yesAdsorption Science & Technology, 2012
Prebiotic isomaltooligosaccharides (IMOs) are composed of α-d-glucose units linked by glucosidic α (1Ø6) bonds and they remain intact until reaching the large bowels, where they are metabolized by bifidobacteria and lactobacillus.

Specific modulation of airway epithelial tight junctions by apical application of an occludin peptide [PDF]

open access: yes, 2006
Tight junctions are directly involved in regulating the passage of ions and macromolecules (gate functions) in epithelial and endothelial cells. The modulation of these gate functions to transiently regulate the paracellular permeability of large solutes
