A multicenter study investigating the genetic analysis of childhood steroid-resistant nephrotic syndrome: Variants in COL4A5 may not be coincidental.

This study aimed to discuss the pathogenic hereditary factors of children with steroid-resistant nephrotic syndrome (SRNS) in Guangxi, China. We recruited 89 patients with SRNS or infantile NS from five major pediatric nephrology centers in Guangxi, and conducted a retrospective analysis of clinical data. Whole-exome sequencing analysis was also performed on all patients.

Tri-channel metasurface fusion of continuously varying gray levels for nanoprinting and holographic displays.

Metasurfaces are extensively utilized in nanoprinting and hologram fusion displays due to their superior wavefront shaping capabilities. However, the creation of continuously varying grayscale images based on conventional Malus's law necessitates the use of at least one polarizer for observation, which compromises the metasurface's integration. In this study, inspired by the Jacobi-Anger expansion, we propose a tri-channel metasurface to establish three independent information channels for simultaneous grayscale nanoprinting and polarization multiplexed holography.

Clinical characteristics and prognosis of steroid-resistant nephrotic syndrome in children: a multi-center retrospective study.

Background: This study investigated the factors influencing the prognosis of children with steroid-resistant nephrotic syndrome (SRNS) in patients from the Guangxi region.

Methods: We retrospectively analyzed clinical and pathological data of 279 patients with SRNS from six tertiary hospitals in Guangxi. Clinical data were compared between initial (I-SRNS) and secondary (S-SRNS) steroid resistance subgroups and Cox regression analysis was used to determine risk factors for chronic kidney disease (CKD) and CKD stage 5 (CKD5) in patients with SRNS.

Discovery of a novel 1H-pyrazole- [3,4-b] pyridine-based lysine demethylase 5B inhibitor with potential anti-prostate cancer activity that perturbs the phosphoinositide 3-kinase/AKT pathway.

Lysine demethylase 5B (KDM5B) is a member of the Jumonji AT-rich interactive domain 1 family. Its main function is to demethylate di/trimethyl histone H3 lysine 4 and it plays a crucial role in the occurrence and development of cancer. In this study, we performed structure-based optimization of KDM5B inhibitors based on our previous work and the most active compound we synthesized was 11ad.
