Evaluating the potential mediating role of ADAMTS13 activity in the relationship between obesity and the severity of COVID-19: A retrospective cohort study.

Obesity and low enzyme A disintegrin and metalloproteinase with thrombospondin type-1 motif-13 (ADAMTS13) activity have been linked to poor coronavirus disease 2019 (COVID-19). Given that obesity may influence ADAMTS13 activity, it is feasible; however, it remains unclear whether ADAMTS13 activity acts as a mediator between obesity and COVID-19 outcomes. We investigated the link between body mass index (BMI) and COVID-19 outcomes, using ADAMTS13 activity as a mediator.

CYP2C8 rs11572080 and CYP3A4 rs2740574 risk genotypes in paclitaxel-treated premenopausal breast cancer patients.

Comparison between stem cell therapy and stem cell derived exosomes on induced multiple sclerosis in dogs.

Background: Multiple sclerosis (MS) is a chronic condition that primarily manifests as demyelination of neuronal axons in the central nervous system, due to the loss or attack of oligodendroglia cells that form myelin. Stem cell therapy has shown promising results for the treatment of MS due to its capability to halt the immune attack, stop apoptosis and axonal degeneration, and differentiate into oligodendrocytes. Stem cell-derived Exosomes (Exosomes) have shown great capabilities for neuronal diseases as they have growth factors, complex sets of miRNA, enzymes, proteins, major peptides, lipids, and macromolecules with anti-inflammatory, angiogenesis, and neurogenesis activities.

Copper-doped magnesium phosphate nanopowders for critical size calvarial bone defect intervention.

Calvarial defects of bone present difficult clinical situations, and their restoration using biocompatible materials requires special treatments that enable bone regeneration. Magnesium phosphate (MgP) is known as an osteoinductive biomaterial because it contains Mg ions and P ions that enhance the activity of osteoplast cells and help in bone regeneration. In this study, MgP and CuO-doped MgP were fabricated and characterized for their physicomechanical properties, particle size, morphology, surface area, antibacterial test, and in vitro bioactivity evaluation using the following techniques: X-rays diffraction, Fourier-transformer infrared, TEM, and Brunauer, Emmett and Teller (BET) surface area, X-rays photoelectron spectroscopy (XPS), and Scanning electron microscopy (SEM).
