Perfusion Bioreactor Culture Incorporating Mechanical Confinement Enhances Mesenchymal Stem Cell Extracellular Vesicle Production and Wound Healing Potential

Advanced Materials Technologies, EarlyView.
Scalable manufacturing challenges and limited potency remain two of the most intransigent issues limiting clinical translation of EV therapeutics. Mechanical cues can induce phenotypic changes and increased vesiculation in EV source cells without the use of extraneous reagents, chemicals, and/or cargo, thereby potentially drastically improving the ...

Experimental determination and prediction of solid-liquid phase equilibria for binary (N-(2-acetoxyethyl)-p-nitroaniline (1) + N-ethyle-4-nitroaniline (2)) mixture

MATEC Web of Conferences, 2013
The nitrocellulose based materials are degraded in a natural way during their storage; the processes of degradation are accelerated when the temperature or the humidity increases.

Cap‐oPMN: Oral Inflammatory Load Quantification Using Capillary Microfluidics and Automated Image Processing

Advanced Materials Technologies, EarlyView.
ABSTRACT Quantifying oral polymorphonuclear neutrophils (oPMNs) is a clinically validated approach for assessing periodontal inflammation. However, current methods, such as manual hemocytometry and flow cytometry, are time‐consuming (>3 h), require invasive sampling, and depend on staining and complex instrumentation, making them unsuitable for point ...

From monoclonal antibody to gene for a neuron-specific glycoprotein in Drosophila [PDF]

, 1985
A monoclonal antibody (MAb24B10), derived from mice immunized with Drosophila retina, exclusively stains photoreceptor cells in the retina and their axonal projections to the optic ganglia. The antigen (Ag24B10) is a 160-kDa glycoprotein comprising about

Cell Cycle Control of Nuclear Metabolism Couples Phosphatidylinositol Signaling to Histone Methylation

Advanced Science, EarlyView.
Nuclear metabolism oscillates during cell cycle progression. Quantitative chromatome proteomics and imaging reveal phase‐specific dynamics of PIP5K1A and nuclear PIP2, linking phosphatidylinositol metabolism to histone methylation. This work identifies nuclear lipid metabolism as a previously unrecognized regulatory axis coordinating chromatin ...

Studying Nitrocellulose Decomposition Process in Nitrocellulose-Cellulose-Trinitrotoluene System

VNU Journal of Science: Natural Sciences and Technology
This study presents the results of determining the kinetic parameters of the decomposition process of system Nitrocellulose-Cellulose-Trinitrotoluene. The kinetic parameters were determined based on differential scanning calorimetry (DSC) data using the Kissinger and Ozawa methods of NC in the samples of NC, NC-Cellulose, NC-Trinitrotoluene dissolved ...

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,

Molecular characterization of an anion pump. The ArsB protein is the membrane anchor for the ArsA protein [PDF]

, 1990
R-factor mediated bacterial resistance to arsenical salts occurs by active extrusion of the toxic oxyanions from cells of gram negative bacteria. The ars operon of the conjugative plasmid R773 encodes an anion pump.
