Article Abstract

Hierarchical zeolites offer improved mass transfer and catalytic performance, yet their controlled synthesis remains challenging. We report a one-pot synthesis of size-tunable, rod-shaped aligned ZSM-5 (RA-ZSM-5) using tetraethylammonium and tetrabutylammonium hydroxides. The crystallization mechanism and improved mass diffusion associated with the hierarchical structure are elucidated.

Bisphenol A (BPA) is a persistent organic pollutant with toxic effects on human health and ecosystems. In this study, the performance of MWCNT-OH functionalized with iron nanoparticles (MWCNT-OH@Fe) using sugarcane bagasse extract as a reducing agent (green synthesis) was evaluated for BPA adsorption. The kinetics are fast, between 10 and 20 min in the range of concentrations evaluated and the resistance to external film diffusion (external film mass transfer) identified as the rate-limiting step of the process.

Introduction: Anti-N-methyl-D-aspartate receptor (NMDA-R) encephalitis is a neuropsychiatric disorder with additional psychiatric features caused by NMDA-R immunoglobulin G (IgG) antibodies in cerebrospinal fluid (CSF). This report presents the follow-up of a patient in whom we assumed mild NMDA-R encephalitis in the first psychotic episode.

Case Study: A patient with a prior episode of an acute polymorphic psychotic syndrome relapsed five and a half years later following a severe COVID-19 infection.

Cadmium (Cd) contamination in water poses a critical global challenge. A novel nanocomposite, montmorillonite (Mt)-supported nanoscale zero-valent iron (Mt-nZVI), synthesized by liquid phase reduction, offers a promising method for effectively removing Cd. The material underwent characterization through various techniques, including X-ray diffraction (XRD) and Scanning Electron Microscope(SEM).

Primary bladder diffuse large B-cell lymphoma: A rare case report.

Int J Surg Case Rep

September 2025

Department of Urology, The Second Affiliated Hospital, Kunming Medical University, Yunnan Province, China. Electronic address:

Introduction: Diffuse large B-cell lymphoma (DLBCL), a common subtype of non-Hodgkin lymphoma (NHL), originates primarily from lymph nodes, with a small proportion arising extranodally in sites such as the gastrointestinal tract and central nervous system. Given the general absence of lymphoid tissue in the bladder, primary bladder DLBCL is exceptionally rare.

Case Presentation: This case report describes an 83-year-old male patient with a bladder mass, initially suspected as cystitis glandularis, ultimately diagnosed via pathological examination as DLBCL.

Introduction And Importance: Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma, yet primary renal involvement is rare, constituting less than 1 % of renal malignancies. A case of non-germinal center B-cell-like (non-GCB) DLBCL with BCL-6 positivity is particularly unique. Conventionally, BCL-6 is linked to germinal center B-cell-like (GCB) subtypes.
