Outcome of Patients With Central Nervous System Multiple Myeloma (CNS-MM) Treated With CNS-Directed Radiation Therapy.

Background: The prognosis of multiple myeloma involving the central nervous system (CNS-MM) is poor. We report outcomes of CNS-MM treated with CNS-directed radiation therapy (RT).

Methods: We retrospectively reviewed patients with CNS-MM treated with CNS-directed RT from 2015 to 2024.

Multiple DNA repair pathways prevent acetaldehyde-induced mutagenesis in yeast.

Acetaldehyde is the primary metabolite of alcohol and is present in many environmental sources including tobacco smoke. Acetaldehyde is genotoxic, whereby it can form DNA adducts and lead to mutagenesis. Individuals with defects in acetaldehyde clearance pathways have increased susceptibility to alcohol-associated cancers.

Bimetallic PdPt nanoparticle-incorporated PEDOT:PSS/guar gum-blended membranes for enhanced CO separation.

To address the escalating demand for efficient CO separation technologies, we introduce novel membranes utilizing natural polymer guar gum (GG), conjugate polymer (poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)) PEDOT:PSS, and bimetallic PdPt nanoparticles. Bimetallic PdPt nanoparticles were synthesized using the wet chemical method and characterized using X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) techniques. The morphologies, chemical bonds, functional groups, and mechanical properties of the fabricated membranes were characterized using various techniques.

Bimetallic PdPt Nanoparticles Decorated PES Membranes for Enhanced H Separation.

Hydrogen separation has significant importance in diverse applications ranging from clean energy production to gas purification. Membrane technology stands out as a low-cost and efficient method to address the purpose. The development of efficient gas-sensitive materials can further bolster the membrane's performance.
