Gut Epithelial Barrier Function is Impacted by Hyperglycemia and Secondary Bile Acids in Vitro: Possible Rescuing Effects of Specific Pectins

Molecular Nutrition &Food Research, Volume 68, Issue 11, June 2024.
Specific BAs are involved in maintenance of gut barrier function. BA metabolism may be disturbed in IBD and diabetes. This might be solved by supplementing the diet with specific dietary fibers such as DM19HB and DM43HB pectins. Gut epithelial barrier disruption is commonly observed in Western diseases like diabetes and inflammatory bowel disease (IBD).

Influence of xylan content on the oxygen delignification performance of eucalypt kraft pulps as studied using prehydrolysis and xylanase treatments [PDF]

BioResources, 2012
Common metrics for evaluating the efficiency of oxygen delignification include the kappa number and Klason lignin content. As a change in xylan content often leads to a change in HexA content, the kappa number must be corrected for the HexA contribution ...

Incorporating Nanoparticles in Porous Foam Templating for Enhanced Sensitivity of Capacitive Pressure Sensors

Advanced Sensor Research, Volume 3, Issue 5, May 2024.
This work introduces the incorporation of silica nanoparticles (SNPs) in the templating process of porous foams for capacitive pressure sensors. The SNPs change the microstructures and porosity of the foams, which results in significant enhancement of sensitivity for pressures below 2 kPa, leading to linearization of sensitivity of the pressure sensor ...

Improved Cellulose Yield in the Production of Dissolving Pulp from Bamboo Using Acetic Acid in Prehydrolysis

BioResources, 2014
Despite increasing demand for dissolving pulps from raw material, production costs remain quite high compared to regular paper pulp. Research literature to date has focused on improving performance and quality but has not simultaneously explored how to ...

ATPase mechanism of the 5'-3' DNA helicase, RecD2: evidence for a pre-hydrolysis conformation change [PDF]

, 2013
The superfamily 1 helicase, RecD2, is a monomeric, bacterial enzyme with a role in DNA repair, but with 5'-3' activity unlike most enzymes from this superfamily. Rate constants were determined for steps within the ATPase cycle of RecD2 in the presence of

Lignin studies I. Investigations concerning lignin determination

Agricultural and Food Science, 1957
In this investigation a sulphuric acid method for the determination of lignin is presented and the influence of various details critically studied. The samples ground to pass through a 60 mesh (0.25 mm.) screen gave 0—5 % smaller results than those ...

Current Approaches on Natural Fiber Reinforcement Surface Treatment for Construction Material Application

International Journal of Polymer Science, Volume 2024, Issue 1, 2024.
The conversion of waste into value‐added products is critical to long‐term sustainability as waste disposal costs, landfilling space, and climate change would be reduced. Research and production industries investigate the possible use of natural fibers as a substitute for fossil fuels.

An Effective Sol‐Gel‐Functionalized Polyurethane Foams Solid Platform Packed Minicolumns for Complete Extraction of Chromium (VI) from Water: Kinetic, Sorption Isotherms, Thermodynamic Study, and Analytical Utility

International Journal of Analytical Chemistry, Volume 2024, Issue 1, 2024.
In the modern era, sol‐gel plays a key role in the progress of a new generation of dispersive solid‐phase microextractors (d–µ SPMEs) for the removal of organic and inorganic pollutants in complex matrices. Thus, the current study reports the use of sol‐gel‐functionalized polyurethane foams (PUFs) as a novel solid platform for complete extraction of ...
