Exploring vaginal microbiota–tissue resident stem cell crosstalk: VCAM1/Akt signaling ‐mediated enhancement of regenerative capacity

Interdisciplinary Medicine, EarlyView.
Vaginal microbiota‐derived secretory factors enhance the regenerative capacity of human endometrial stem cells by upregulating VCAM1 and activating PI3K/Akt signaling. This microbiota–stem cell crosstalk promotes self‐renewal, migration, multilineage differentiation, and metabolic reprogramming in vitro and in vivo, establishing a novel microbiota ...

Protective Role of Polydatin Against Vancomycin‐Induced Lung Toxicity via Oxidative Stress, Inflammation, Endoplasmic Reticulum Stress, Apoptosis, and Ferroptosis Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study aimed to evaluate whether polydatin (Poly) could eliminate the harmful effects of vancomycin (VCM) on the lungs of rats. Rats were administered VCM (200 mg/kg) and Poly (50 mg/kg), both separately and in combination, for a duration of 7 days.

Platelet‐Rich Fibrin (PRF) Application and Education in US Graduate Programs: A Cross‐Sectional Study

Journal of Dental Education, EarlyView.
ABSTRACT The aim of this cross‐sectional study was to assess platelet‐rich fibrin (PRF) application and education in clinical use among US graduate periodontology, endodontic, and oral and maxillofacial surgery programs. A survey questionnaire was electronically distributed to 84 oral and maxillofacial surgery (OMFS), 46 endodontic, and 46 ...

Gamma Irradiation‐Based Free Radical Grafting of N‐Hydroxyethyl Acrylamide onto Poly[(R)‐3‐hydroxybutyrate]

Macromolecular Rapid Communications, EarlyView.
This work demonstrates successful gamma‐radiation‐induced grafting of N‐hydroxyethyl acrylamide onto poly[(R)‐3‐hydroxybutyrate], producing substantial changes in material properties. Grafting generated a biphasic, less crystalline structure with enhanced thermal stability, elongation (65%), toughness (378% increase), and exceptional water uptake (610 ...

Single-Phase Autonomous Induction Generator with Single-Phase Rotor

Energies, 2017
An autonomous induction generator (IG) with an asymmetric configuration, in which both the stator and the rotor are single-phase, is often formed when a triple-phase wound rotor loses connection to a winding component while running.

Real-Time Simulation of Power Conversion in Doubly Fed Induction Machine

Energies, 2020
Currently used methods of simulation of doubly fed induction machines (DFIM), especially in real-time simulators (where a relatively large calculation step is used and high adequacy is required), do not provide the required adequacy, especially in rotor ...
