Management of mass casualty incidents: a systematic review and clinical practice guideline update.
Eur J Trauma Emerg Surg
January 2025
Institute for Research in Operative Medicine (IFOM), Faculty of Health, School of Medicine, Witten/Herdecke University, Ostmerheimer Str. 200, 51109, Cologne, Germany.
Purpose: Our aim was to generate evidence- and consensus-based recommendations for the management of mass casualty incidents (MCIs) based on current evidence. This guideline topic is part of the 2022 update of the German guideline on the treatment of patients with severe/multiple injuries.
Methods: MEDLINE and Embase were systematically searched to August 2021.
Mustard Gas Induced Corneal Injury Involves Ferroptosis and p38 MAPK Signaling.

January 2025
Harry S. Truman Memorial Veterans' Hospital, Columbia, Missouri, United States.
Purpose: Sulfur mustard gas (SM) exposure to eyes causes multiple corneal injuries including stromal cell loss in vivo. However, mechanisms mediating stromal cell loss/death remains elusive. This study sought to test the novel hypothesis that SM-induced toxicity to human corneal stromal fibroblasts involves ferroptosis mechanism via p38 MAPK signaling.

College of Biotechnology and Pharmaceutical Engineering, State Key Laboratory of Materials-Oriented Chemical Engineering, Nanjing Tech University, Nanjing 211816, P.R. China.
To enhance production efficiency, curtail costs, and minimize environmental impact, developing simple and sustainable nanozyme synthesis methods has been the focus of relevant research. In this report, graphite-coated CeO nanoparticles (CeO NPs) with multiple defects (Ce defects, oxygen vacancies and carbon defects) were synthesized the culture filtrate of the extremely radioresistant bacterium R12 ( R12). The as-prepared CeO NPs exhibit remarkable oxidase (OXD)-like activity, efficiently catalyzing the oxidation of the chromogenic substrate 3,3',5,5'-tetramethylbenzidine (TMB) to form oxTMB, even in the absence of HO.

The emergence of carbapenem-resistant (CRKP) poses a significant public health threat, particularly in low- and middle-income countries (LMICs) with limited surveillance and treatment options. This study examines the genetic diversity, resistance patterns, and transmission dynamics of 66 CRKP isolates recovered over 5 years (2015-2019) after the first case of CRKP was identified at a tertiary care hospital in Lima, Peru. Our findings reveal a shift from to as the dominant carbapenemase gene after 2017.

A theoretical description of various [AeX] (Ae = Be-Ba, X = F-I) systems, some of which have been reported in the literature to bear an unusual quadruple bond between the metal and the halogen, is provided based on both (i) the localization of the Fermi hole and (ii) the topological analysis of the one-electron density. Insights into the bond order of various [AeX] systems are inferred on the basis of the number of electrons localized in the bond basin, the topology of the Fermi hole information computed along the bond axis, and the delocalization index. The results suggest that the [AeX] molecules present a bond with attributes closer to a classical dative bond than to a multiple one, being characterized by large stabilization due to the electrostatic interaction between the polarized metal and the halogen anion.
