The morphologic and pathologic changes which occurred within the cecal mucosa of 4 horses during the onset of laminitis were determined from cecal biopsy materials obtained via a cecal fistula; the laminitis was induced with carbohydrate overload. The cecal epithelial mucosa specimens were obtained at 0 (base line), 24, 32, 48, and 72 hours after horses were given carbohydrate overload, and these were fixed and subsequently photographed. Changes in the cecal epithelium were examined by transmission electron and scanning electron microscopies. These histopathologic changes indicated that the mucosal barrier was substantially damaged by the carbohydrate overload.

Introduction: Serum levels of interleukin-6 (IL-6) are increased in COVID-19 patients. IL-6 is an effective therapeutic target in inflammatory diseases and tocilizumab, a monoclonal antibody that blocks signaling via the IL-6 receptor (IL-6R), is used to treat patients with severe COVID-19. However, the IL-6R exists in membrane-bound and soluble forms (sIL-6R), and the sIL-6R in combination with soluble glycoprotein 130 (sgp130) forms an IL-6-neutralizing buffer system capable of neutralizing small amounts of IL-6.

The multiple enzymatic properties of the Au-modified metal-organic framework (Au-MOFs) have made it a functional catalytic system for antitumor treatment. However, in the face of insufficient catalytic substrates in tumor tissue, it is still impossible to achieve efficient treatment of tumors. Herein, Au-MOFs loaded with hyaluronic acid (HA)-modified calcium peroxide nanoparticles (CaO NPs) were used to construct a nanozyme (Au-MOF/CaO/HA) for substrate self-supplied and parallel catalytic/calcium-overload-mediated therapy of cancer.

Iron overload in transfusion-dependent thalassemia patients represents a significant public health challenge due to its high mortality rate and risks of severe complications. Therefore, developing safe and effective therapeutic modalities for managing iron overload is critical, as current animal models inadequately replicate human conditions. The aim of this study was to investigate the effects of intravenous iron dextran on hepatocyte morphology, liver iron concentration, and serum iron profile changes as a model for hemochromatosis.

Along with the synthetic drugs, numerous traditional and functional food approaches are equally trialed to eradicate the problem. As a prospective new source of dietary protein hydrolysates, freshwater mollusks () have recently drawn huge interest from researchers.

Parietal Epithelial Cells (PECs) activation and proliferation are common to several distinct forms of glomerulopathies. Due to several stimuli, PECs can change to a progenitor (CD24 and CD133/2) or a pro-sclerotic (CD44) phenotype. In addition, PECs, which are constantly exposed to filtered albumin, are known to be involved in albumin internalization, but how this mechanism occurs is unknown.
