Cardiovascular (CV) diseases are the most commonly encountered etiology of mortality in patients having kidney failure. β-Trace protein (BTP) is a biomarker of glomerular filtration function as well as a potential predictor of adverse CV outcomes. This study aimed to determine the prognostic value of BTP in patients on chronic hemodialysis (HD). A total of 96 patients undergoing HD were enrolled. Baseline variables were collected, and the patients were tracked for 3 years. Twenty-five patients died at 3 years. Those who experienced mortality were noted to have higher serum concentrations of BTP and a higher incidence of diabetes mellitus (DM). The area under the receiver operating characteristic curve for serum BTP distinguishing mortality from survival was 0.659 (95% confidence interval [CI], 0.555-0.752; = 0.027). After the adjustment of variables potentially affecting survival rates, BTP levels above the median (adjusted hazard ratio [aHR]: 2.913, 95% CI, 1.256-6.754; = 0.013), the presence of DM (aHR: 2.474, 95% CI, 1.041-5.875; = 0.040), and low serum albumin (aHR: 0.298, 95% CI, 0.110-0.806; = 0.017) independently correlated with survival in HD patients. Serum BTP is a novel biomarker for predicting overall outcomes in HD patients.

Background: There is still a significant proportion of patients with rheumatoid arthritis (RA) in whom multiple therapeutic lines are ineffective. These cases are defined by the EULAR criteria as Difficult-to-Treat RA (D2T-RA) for which there is limited knowledge of predisposing factors.

Objective: To identify the clinical features associated with D2T-RA in real-life practice.

The therapeutic role of naringenin nanoparticles on hepatocellular carcinoma.

BMC Pharmacol Toxicol

January 2025

Biochemistry Department, Faculty of Science, Tanta University, Tanta, Egypt.

Background: Naringenin, a flavonoid compound found in citrus fruits, possesses valuable anticancer properties. However, its potential application in cancer treatment is limited by poor bioavailability and pharmacokinetics at tumor sites. To address this, Naringenin nanoparticles (NARNPs) were prepared using the emulsion diffusion technique and their anticancer effects were investigated in HepG2 cells.

Background: Synthesis of organic@inorganic hNFs is achieved by the coordination of organic compounds containing amine, amide, and diol groups with bivalent metals. The use of bio-extracts containing these functional groups instead of expensive organic inputs such as DNA, enzymes, and protein creates advantages in terms of cost and applicability. In this study, the application potentials (antioxidant, antibacterial, anticancer, guaiacol, anionic, and cationic dye degradation) of hybrid (organic@inorganic) nanoflowers (hNFs) synthesized with Cu and snakeskin (SSS) were proposed.
