Evaluation of novel surfactants for the decontamination of chemical warfare agents.

Toxicol Mech Methods

September 2025

Department of Toxicology and Military Pharmacy, Military Faculty of Medicine, Hradec Kralove, University of Defence, Brno, Czech Republic.

The decontamination of chemical warfare agents or compounds involved in chemical industry incidents poses a significant challenge to environmental protection and human health. These compounds are highly toxic and could be relatively resistant to conventional decontamination methods. In recent years, surfactants have emerged as a promising option, as they can enhance the solubility of organophosphorus compounds in aqueous solutions while promoting their degradation or adsorption onto surfaces.

EBAMP: An efficient de novo broad-spectrum antimicrobial peptide discovery framework.

Cell Rep

September 2025

State Key Laboratory of Pathogen and Biosecurity, Academy of Military Medical Sciences, Beijing 100071, China. Electronic address:

De novo design of antimicrobial peptides (AMPs) is challenging due to the vast combinatorial space and unknown mechanisms. We propose EBAMP, a generative-discriminative framework for de novo broad-spectrum AMP design targeting bacteria and fungi. EBAMP combines a Transformer-based generative model with advanced feature-based screening to explore peptide space and select multiobjective candidates.

Composite materials have been increasingly used in various branches of industry, transport, construction, and medicine-as well as in other sectors of the economy and science-in recent decades. A significant advancement in the improvement of composite material characteristics has been achieved through the use of nanoparticles, which substantially enhance the properties of the base material, whether it is the matrix or the reinforcing phase in hybrid composites. The broad application of polymers and polymer composites in many areas of engineering has had a significant impact on reducing friction and wear, improving the thermal characteristics of individual components and entire technical systems, enhancing electrical conductivity, reducing the specific weight of components, lowering noise and vibration levels, and ultimately decreasing fuel consumption, production costs, and the costs of operation and maintenance of technical systems.

The Influence of Rolling Direction and Dynamic Strengthening on the Properties of Steel.

Materials (Basel)

August 2025

Institute of Robots & Machine Design, Faculty of Mechanical Engineering, Military University of Technology, 2 Gen. S. Kaliskiego St., 00-908 Warsaw, Poland.

The article presents an analysis of the mechanical properties of S700MC steel, which represents advanced low-alloy high-strength steels. The influence of microstructure, shaped by a controlled thermo-mechanical rolling process, on the strength, ductility, and resistance to cracking and fatigue of the material is discussed. Particular attention is paid to the anisotropy of mechanical properties resulting from the orientation relative to the rolling direction, manifested by variations in yield strength, tensile strength, and total elongation of the specimens.

Background: Occupational noise-induced hearing loss poses a significant health risk, especially for military and law enforcement. Unlike steady, prolonged noise, impulse noise, such as gunfire, leads to more immediate and severe hearing impairment. This study explores the link between sensorineural hearing loss and cytokine levels in nasal secretions of male and female military cadets exposed to high-intensity gunfire noise.

Introduction: Medical evacuation (MEDEVAC) is a crucial component of military healthcare, and the time during which evacuation of the wounded, injured and ill individuals happens is one of the most critical factors. The article focuses on the initial phase of ground evacuation from the Point of Injury to the casualty collection point (CCP). Casualty transport is the combat unit's task, triggered by a 9-liner MEDEVAC request.

August 2025

Department of Radiobiology, Military Faculty of Medicine, University of Defence, Třebešská 1575, Hradec Králové, 500 02, Czech Republic.

The dicentric chromosome assay is a well-established biodosimetric method used to assess absorbed ionizing radiation doses by detecting dicentric chromosomal aberrations. Here, we present a detailed, reproducible protocol for applying the dicentric chromosome assay for evaluation of radioprotective agents, including novel piperazine derivatives compared with amifostine and its active metabolite WR-1065. The protocol covers all key steps-blood sample preparation, irradiation, lymphocyte culture, metaphase preparation, and scoring of dicentric chromosomes.

Juvenile Paget disease with unique compound heterozygous sequence variants in the TNFRSF11B gene.

Orphanet J Rare Dis

August 2025

Department of Clinical Biochemistry and Diagnostics and Osteocenter, University Hospital Hradec Kralove and Faculty of Medicine in Hradec Kralove, Charles University, Sokolska 581, 500 05, Hradec Kralove, Czech Republic.

Background: Juvenile Paget disease (JPD) is a rare autosomal recessive bone disease characterized by escalated bone metabolism leading to skeletal deformities, susceptibility to fractures, and some extraskeletal findings. This genetic disease is associated with changes in the TNFRSF11B gene encoding osteoprotegerin, an important regulator of osteoresorption. Most published JPD cases have been found to carry homozygous TNFRSF11B variants, while compound heterozygous variants in this gene have been reported only twice.

Masked language modeling (MLM) has expanded the exploration of text-image person re-identification (TIReID) tasks from coarse-granularity to fine-grained alignment. Whereas, we note that vanilla MLM picks random tokens for visual-to-token reasoning, which could fail the intention of semantic visual-textual alignment by indistinguishably focusing on all the sub-words. This work proposes to leverage the inherent hierarchical scene graph knowledge in each text for guiding token masking and enhancing cross-modal representation in TIReID, thus relieving the pitfall of blind visual-textual alignment.

Background: The prospect for Bruton's tyrosine kinase (BTK) inhibition to meaningfully affect relapsing multiple sclerosis has recently been questioned due to inconsistent findings in the magnitude and sustainability of the effect of BTK inhibitors on disease activity. We assessed the safety, efficacy, and CSF drug concentrations of fenebrutinib, a highly selective, noncovalent, reversible BTK inhibitor, in patients with relapsing multiple sclerosis.

Methods: This multicentre, double-blind, randomised, placebo-controlled, phase 2 trial (FENopta) was conducted at 18 community centres and hospitals across six countries in Europe and North America.

Department of Military Internal Medicine and Military Hygiene, Military Faculty of Medicine, University of Defence, Hradec Kralove, Czech Republic.

Objectives: The first aim of this cross-sectional study was to reveal the prevalence of overweight and obesity among Czech military personnel (CMP). The second aim was to compare accuracy of the body mass index (BMI) classification with the body fat percentage (BF%), waist circumference (WC), and visceral fat area (VFA). BMI is a commonly used method to assess obesity, but its accuracy in reflecting body composition, especially in physically fit individuals, has been questioned.

This paper presents two discrete circuit solutions for realizing passive, electronically adjustable constant-phase elements, specifically half-order capacitors with a -45° phase shift. Fractional-order capacitors with electronically adjustable pseudocapacitance are especially useful for designing tunable filters and oscillators. The ability to adjust pseudocapacitance electronically and continuously is a major improvement over traditional passive solutions.

The abnormalities in blood coagulation in patients with diabetes can lead to a prothrombotic state and requirement for the administration of direct anticoagulants. However, no comparative studies have been conducted on the effects of different direct anticoagulants. A head-to-head investigation of the impact of anticoagulants in 50 patients of type 1 diabetes mellitus (DMT1) was performed, and the data were compared to 50 generally healthy individuals.
