Background: Single-walled (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) can pose risks in biological systems leading to harmful effects, such as, reactive oxygen species (ROS) formation, DNA damage, mitochondrial dysfunction, and ultimately, the cell death through apoptosis.

Objectives: The study assessed the nephrotoxicity of the SWCNTs and SWCNTs-Ag-TiO nanocomposites through in vitro and in vivo experiments, assessing oxidative stress, genotoxicity, and safety for biomedical applications.

Methodology: In vitro, HK-2 cell lines were utilized to evaluate the effects of nanomaterials on cellular activity, apoptosis, ROS generation, and micronuclei formations.

Article Synopsis
  • - Discrepancies between pulse oximetry and arterial oxygen saturation can complicate clinical assessments, often caused by factors like poor blood flow, skin color, movement, or specific blood conditions.
  • - Unstable hemoglobin variants, such as hemoglobin Köln, are rare genetic mutations that can disrupt the normal structure and function of hemoglobin, affecting its ability to bind oxygen.
  • - This case study highlights a 44-year-old Arabic woman diagnosed with hemoglobin Köln after extensive investigations revealed significant differences between her pulse oximetry readings and arterial oxygen saturation.

Purpose: We aimed to compare recurrence-free survival (RFS) and progression-free survival (PFS) of the patients with pure high-grade (HG) vs mixed-grade (MG) nonmuscle-invasive bladder cancer who received adequate bacillus Calmette-Guérin therapy.

Materials And Methods: We conducted a retrospective cohort analysis using data from an institutional database. The study included patients diagnosed with HG nonmuscle-invasive bladder cancer at the initial transurethral resection specimen between 2010 and 2020.

Key Clinical Message: Rhinovirus infection has the potential to exhibit unconventional symptoms like symptomatic hyponatremia. Health care professionals should remain vigilant about this potential complication, especially in cases with uncommon presentations. Timely identification and effective management of hyponatremia can mitigate potential complications and enhance patient prognosis.

Article Synopsis
  • Blue toe syndrome is a condition where the toes turn blue, and it can be caused by different factors.
  • A 38-year-old man from Saudi Arabia had blue toe syndrome and doctors found out he had very high platelet levels because of not having enough iron in his body.
  • He received treatment with pain relief, blood-thinning medicines, fluids, and iron, and got better after a few days.
