The Role of Intra-Articular Delivery of BM-MSCs-Derived Exosomes in Improving Osteoarthritis: Implication of // Axis.

Background: Bone marrow-derived mesenchymal stem cells (BM-MSCs) have recently attracted great attention due to their crucial anti-inflammatory and regenerative properties. This work aims to examine the curative impact of intra-articular injection of BM-MSCs-derived exosomes in ameliorating osteoarthritis (OA) progression in rats and to explore the interaction between circular RNA of Yes-associated protein 1 () and microRNA-21 () in the rat knee joints.

Methodology: Gene expression , , toll-like receptor-7 (), aggrecan, and collagen type II were evaluated by quantitative reverse transcription polymerase chain reaction (qRT-PCR) in the rat articular tissues.

Diagnostic Value of Combined BCOR, Cyclin D1, and CD10 in Differentiating Endometrial Stromal Sarcoma From Other Uterine Spindle Cell Lesions.

Uterine spindle cell lesions share a dilemmatic overlapped features that needed to be addressed by the pathologist to reach a conclusive accurate diagnosis for its prognostic value and different management decisions. Usage of combined IHC panel can be an aiding guiding tool in this context. The aim of this study is to evaluate the diagnostic value of combined BCOR, Cyclin D1, and CD10 IHC panel in differentiating endometrial stromal sarcoma from other uterine spindle cell lesions.

TLR4, IgA and EpCAM Expression in Colorectal Cancer and Their Possible Association with Microbiota as a Pathogenic Factor; An Immunohistochemical and Genetic Study.

Background: The pathogenesis of inflammatory bowel disease (IBD) and colorectal cancer (CRC) is thought to be related to immune response against gut microbiota. TLR4, IgA, and EpCAM have a role in intestinal local immune response and their altered expression related to both IBD and CRC. Lipopolysaccharide (LPS) is the main activator of TLR4.

and studies of -loaded electrospun PLGA/PMMA/collagen nanofibers for accelerating topical wound healing.

This work aims to develop plant extract-loaded electrospun nanofiber as an effective wound dressing scaffolds for topical wound healing. Electrospun nanofibers were fabricated from leaf extract (SCLE), poly(lactic--glycolic acid) (PLGA), poly(methyl methacrylate) (PMMA), collagen and glycine. Electrospinning conditions were optimized to allow the formation of nanosized and uniform fibers that display smooth surface.

Transcranial Irradiation Mitigates Paradoxical Sleep Deprivation Effect in an Age-Dependent Manner: Role of BDNF and GLP-1.

The growing prevalence of aged sleep-deprived nations is turning into a pandemic state. Acute sleep deprivation (SD) accompanies aging, changing the hippocampal cellular pattern, neurogenesis pathway expression, and aggravating cognitive deterioration. The present study investigated the ability of Near Infra Red (NIR) light laser to ameliorate cognitive impairment induced by SD in young and senile rats.
