Background: The clinical significance and optimal management of supranormal differential renal function (DRF ≥ 55%) in pediatric ureteropelvic junction obstruction (UPJO) remain debated. This study investigated supranormal DRF clinical characteristics and evaluated surgical versus conservative management outcomes to guide decision-making.
Methods: We retrospectively reviewed 76 children with unilateral UPJO who underwent standardized DMSA and DTPA scans at a single center (2020-2022).
Modulation of copper-induced neurotoxicity by monoisoamyl 2,3-dimercaptosuccinic acid loaded nanoparticles through inhibition of mitophagy and reduction of oxidative stress in SH-SY5Y cells.

Copper (Cu) dysregulation, often stemming from ATP7B gene mutations, exacerbates neurological disorders like Huntington's, Alzheimer's, and Parkinson's diseases. Monoisoamyl 2,3-dimercaptosuccinic acid (MiADMSA) shows promise in mitigating Cu induced neurotoxicity by chelating intracellular Cu ions, reducing oxidative stress, and restoring antioxidant enzyme function. However, challenges such as poor bioavailability hinder its therapeutic efficacy.

Copper plays an important role in the regulation of PD-L1, suggesting that reducing copper levels within tumors may enhance anti-cancer immunotherapy. Tumor microenvironment responsive copper nanodeprivator (TMECN) was developed for enhancing immunotherapy of tumor via the cross-link of mercaptopolyglycol bipyridine and dimercaptosuccinic acid modifying FePt nanoalloy using the disulfide bond. Upon entering tumor cells, the disulfide bond in TMECN is cleaved by the overexpressed glutathione, exposing abundance of sulfhydryl groups.

The incidence of urinary tract infection (UTI) caused by extensive beta-lactamase-producing Escherichia coli (ESBL-EC) is increasing, including in children. However, the available oral antibiotic treatment options for ESBL-EC are limited. Herein, we report the cases of two children diagnosed with UTI caused by ESBL-EC (ESBL-UTI) who were switched from empirical intravenous antibiotics in UTI to amoxicillin-clavulanic acid (AMPC/CVA) (14:1) after the causative organism was found to be ESBL-EC.

Background: Severe Acute Respiratory syndrome coronavirus 2 (SARS-CoV-2) and Influenza A viruses (IAVs) are among the most important causes of viral respiratory tract infections, causing similar symptoms. IAV and SARS-CoV-2 infections can provoke mild symptoms like fever, cough, sore throat, loss of taste or smell, or they may cause more severe consequences leading to pneumonia, acute respiratory distress syndrome or even death. While treatments for IAV and SARS-CoV-2 infection are available, IAV antivirals often target viral proteins facilitating the emergence of drug-resistant viral variants.
