Experimental studies of the influence of the characteristics of the metal bond coat on the durability of the heat-protective coating of the turbine blades of a gas turbine engine

The service life of gas turbine engine (GTE) turbine blades with thermal barrier coatings (TBC) depends on many factors, including the composition, structure and properties of the metal bond coating (MB). The positive effect of using TBC is...

PPP2R1A-mediated tumor-stromal adhesion as an unrecognized mechanism of immunosuppression.

Elevated Eosinophils as a Feature of Inflammation Associated With Hypertension in Virally Suppressed People Living With HIV

Background People living with HIV (PLWH) are at increased risk of cardiovascular disease, including hypertension, which persists despite effective plasma viral suppression on antiretroviral therapy. HIV infection is characterized by long‐te...

Formulation, characterization, and valorization of the antioxidant, antibiofilm, and anti-adhesion potentials of a clove essential oil nanoemulsion

Food safety and control are fundamental public health issues that maintain consumer confidence and protection. This design (management) requires monitoring production, processing, and conservation processes while limiting microbiological, c...

Nanotechnology

Nanotechnology is the study, production and controlled manipulation of materials with a grain size < 100 nm. At this level, the laws of classical mechanics fall away and those of quantum mechanics take over, resulting in unique behaviour of...

Emerging nanomaterials for novel wound dressings: From metallic nanoparticles and MXene nanosheets to metal-organic frameworks

The growing need for developing reliable and efficient wound dressings has led to recent progress in designing novel materials and formulations for different kinds of wounds caused by traumas, burns, surgeries, and diabetes. In cases of ext...

ITRI Biofilm Prevented Thoracic Adhesion in Pigs That Received Myocardial Ischemic Induction Treated by Myocardial Implantation of EPCs and ECSW Treatment

This study tested the hypothesis that ITRI Biofilm prevents adhesion of the chest cavity. Combined extracorporeal shock wave (ECSW) + bone marrow-derived autologous endothelial progenitor cell (EPC) therapy was superior to monotherapy for i...

Roles of Rap1 signaling in tumor cell migration and invasion

Ras-associated protein-1 (Rap1), a small GTPase in the Ras-related protein family, is an important regulator of basic cellular functions (e.g., formation and control of cell adhesions and junctions), cellular migration, and polarization. Th...

In vivo topology converts competition for cell-matrix adhesion into directional migration

Migrating cells encounter multiple signals such as extracellular matrix (ECM) and chemokinetic factors but how these integrate in vivo is unclear. Here, the authors report that overall control of cell-ECM adhesion by Sema3A and Sdf1 can be ...

Identification of functional pathways for regenerative bioactivity of selected renal cells

Abstract Background Selected renal cells (SRC) are in Phase II clinical trials as a kidney-sourced, autologous, tubular epithelial cell-enriched cell-based therapy for chronic kidney disease (CKD). In preclinical studies with rodent models ...

Dysregulation of Angiogenesis and Inflammatory Genes in Endometrial Mesenchymal Stem Cells and Their Contribution to Endometriosis

Endometriosis is a common, chronic, inflammatory disorder in women, characterized by the presence of endometrial tissue outside the uterus cavity. The disease affects ~10% of women during their reproductive age. There is some debates on the...

Assessment of Safety and Probiotic Traits of Enterococcus durans OSY-EGY, Isolated From Egyptian Artisanal Cheese, Using Comparative Genomics and Phenotypic Analyses

An Enterococcus durans strain, designated OSY-EGY, was previously isolated from artisanal cheese. In this work, comparative genomic and phenotypic analyses were utilized to assess the safety characteristics and probiotic traits of the bacte...

TEMPERATURE OF SLIDING SURFACES OF INTERNAL COMBUSION ENGINES BY THE TEMPER COLORS OF WEAR PARTICLES

The present study examines the temper colors of the wear particles retained by the oil filter by optical microscope. The temperature of the sliding surfaces inside engines can be determined by the temper colors of the wear particles. Becaus...

Semi-Resolved CFD-DEM Study on the Influence of ‘Surface Energy’ Factors on the Deposition of Lignin Particles in Ceramic Membrane Pores

This study adopted a semi‑analytical CFD‑DEM coupling method to simulate the movement and deposition of lignin particles in ceramic membrane pores, with the aim of elucidating the microscopic mechanisms of membrane fouling. The movement of ...

Isoliquiritigenin Attenuates Staphylococcus aureus Adhesion and Invasion to Counteract Staphylococcus aureus Pathogenicity and Infection

IntroductionMethicillin-resistant Staphylococcus aureus (MRSA) is a major clinical challenge due to its virulence and multidrug resistance. Antivirulence strategies targeting key pathogenic mechanisms without affecting bacterial viability p...

Correlating single-molecule rupture mechanics with cell population adhesion by yeast display

Here, we present a method based on yeast surface display that allows for direct comparison between population-level cell adhesion strength and single-molecule receptor-ligand rupture mechanics. We developed a high-throughput yeast adhesion ...

Formulation, development and evaluation of buccoadhesive drug delivery system of risperidone

Aim and Objective: The study aimed to manufacture Bucco-adhesive tablets of Risperidone and characterize the effectiveness of the drug by incorporating it into the mucoadhesive drug delivery system. The sustained release tablets reduced the...

The Influence of Applying PVD Coatings on Adhesion Wear Resistance of Quenching and Tempering Steels

The article examines the effect of different types of two-layer nanostructured coatings (cVIc and nACVIc) deposited on three types of steel substrates, 45S20, C45E, and 42CrMo4, to determine the resistance to adhesive wear of the substrate/...

Concurrent acute cystitis, pancolitis, and tubo-ovarian abscess following laparoscopic ovarian cystectomy: a case report
