Extraglomerular cortex and medulla structural elements of kidneys, obtained from 10 male normal rabbits and 10 human beings (8 male and 2 female), who died from accidents at the age of 16-40 years, were studied in comparison. Morphometric studies with statistical evaluation are presented in diagrams, showing the percentage correlation of structural elements of rabbit and human kidneys. It is shown that the difference in life conditions of the studied species may result in the difference of these correlations The obtained results must be taken in to account in the comparative study of pathologic processes in the human and rabbit kidneys.

Evaluation of Complement-Dependent Cytotoxicity Assays for Gene-Edited Pig-to-Human Xenotransplantation.

Background: Gene-edited pigs for xenotransplantation usually contain one or more transgenes encoding human complement regulatory proteins (CRPs). Because of species differences, human CRP(s) expressed in gene-edited pigs may have difficulty inhibiting the activation of exogenous rabbit complement added to a complement-dependent cytotoxicity (CDC) assay. The use of human complement instead of rabbit complement in CDC experiments may more accurately reflect the actual regulatory activity of human CRP(s).

Objectification, being perceived and treated merely as an object with a denial of one's humanness, has been linked to numerous adverse outcomes in daily life. Despite this, its influence on online behaviors, particularly problematic gaming, remains underexplored. The current research (total = 1,000) extends the literature on objectification by investigating the effect of objectification on problematic gaming.

A successful therapeutic outcome in the treatment of solid tumours requires efficient intratumoural drug accumulation and retention. Here we demonstrate that zinc gluconate in oral supplements assembles with plasma proteins to form ZnO nanoparticles that selectively accumulate into papillary Caki-2 renal tumours and promote the recruitment of dendritic cells and cytotoxic CD8 T cells to tumour tissues. Renal tumour targeting is mediated by the preferential binding of zinc ions to metallothionein-1X proteins, which are constitutively overexpressed in Caki-2 renal tumour cells.

Cataracts are significant causes of blindness, closely linked to prolonged hypercholesterolemia. While saffron has the potential for eye health, its effects on lens lesions remain understudied. This study aimed to investigate the effect of saffron on the lens changes in atherosclerotic-induced New Zealand white rabbits (NZWR).

The shortage of corneal donors and the limitations in tissue engineering grafts, such as biocompatibility and mechanical properties, pose significant challenges in corneal transplantation. Here, for the first time, we investigate the effect of Rho kinase inhibitor Y-27632 and a dual media culture approach, including proliferative media (M1) and stabilizing media (M2), on rabbit limbal epithelial stem cells (LESCs), aiming to explore the feasibility of constructing corneal cell sheets in vitro through auto-bioprinting and assessing their corneal wound healing capacity in vivo. Y-27632 has primarily demonstrated significantly enhanced LESCs growth, proliferation, and reduced apoptosis.
