Humans are frequently exposed to aluminum from various food additives, therapeutic treatments and the environment, and it can be potentially toxic. This study is aimed to elucidate the protective effects of propolis against aluminum chloride (AlCl3 )-induced histopathological and immunohistochemical changes in kidney tissues of rats. Sixty Wistar Albino male rats (average weight 250-300 g) were divided into three equal groups. The first served as a negative control. The second received AlCl₃ (34 mg/kg bw, 1/ 25 LD 50). The third were administered AlCl₃ (34 mg/kg bw, 1/ 25 LD 50) plus propolis (50 mg/kg bw). Doses were given once daily via a gavage for 8 weeks every day. The results showed that shrunken glomeruli, intraglomerular congestion, loss of apical microvilli, degeneration of mitochondria and widened rough endoplasmic reticulum were also observed in the Proximal Convoluted Tubules of these animals. Treatment with propolis ameliorated the harmful effects of AlCl₃ ; this was also proved histopathologically by the noticeable improvement in the renal tissues. There were also significant variations in the expressed of ki-67 and p53 proteins. It can be concluded that propolis may be promising as a natural therapeutic agent in AlCl₃ -induced renal toxicity and oxidative stress in rat kidneys.

Background And Objective: Fexofenadine is commonly used as a probe substrate to assess P-glycoprotein (Pgp) activity. While its use in healthy volunteers is well documented, data in older adult and polymorbid patients are lacking. Age- and disease-related physiological changes are expected to affect the pharmacokinetics of fexofenadine.

Aim: This study aimed to explore the possible bidirectional interrelations between fructose-induced metabolic syndrome (MS) and apical periodontitis (AP).
Methodology: Twenty-eight male Wistar rats were distributed into four groups (n = 7, per group): Control (C), AP, Fructose Consumption (FRUT) and Fructose Consumption and AP (FRUT+AP). The rats in groups C and AP received filtered water, while those in groups FRUT and FRUT+AP received a 20% fructose solution mixed with water to induce MS.

Aim: Proteinuria is the most robust predictive factors for the progression of chronic kidney disease (CKD), and interventions targeting proteinuria reduction have shown to be the most effective nephroprotective treatments to date. While glomerular dysfunction is the primary source of proteinuria, its consequences extend beyond the glomerulus and have a profound impact on tubular epithelial cells. Indeed, proteinuria induces notable phenotypic changes in tubular epithelial cells and plays a crucial role in driving CKD progression.

Objective: Although left ventricular hypertrophy frequently accompanies end-stage renal disease, heart failure (HF) with reduced ejection fraction (EF) is also observed in a subset of patients. In those patients kidney transplantation (KT) is generally avoided due to an increased risk of mortality in addition to the risks associated with HF. This prospective study was designed to follow patients with HF who were being prepared for KT.

Ribosomal S6 protein kinase 4 (RSK4), a member of the serine‒threonine kinase family, plays a vital role in the Ras‒MAPK pathway. This kinase is responsible for managing several cellular activities, including cell growth, proliferation, survival, and mobility. In this study, we observed higher RSK4 protein expression in clear cell renal cell carcinoma (ccRCC) than in normal kidney tissue, and the overexpression of RSK4 might predict poor outcomes for ccRCC patients.
