Most casualty or personnel decontamination studies have focused on removing contaminants from the skin. However, scalp hair and underlying skin are the most likely areas of contamination following airborne exposure to chemicals. The aim of this study was to investigate the interactions of contaminants with scalp hair and underlying skin using a hybrid in vitro diffusion cell model. The in vitro hybrid test system comprised "curtains" of human hair mounted onto sections of excised porcine skin within a modified diffusion cell. The results demonstrated that hair substantially reduced underlying scalp skin contamination and that hair may provide a limited decontamination effect by removing contaminants from the skin surface. This hybrid test system may have application in the development of improved chemical incident response processes through the evaluation of various hair and skin decontamination strategies.

The sluggish kinetics and diffusion of lithium polysulfide (LiPS) intermediates lead to the decline in the capacity and rate of high-energy lithium-sulfur (Li-S) batteries. Integrating adsorbents and electrocatalysts into the Li-S system is an effective strategy for suppressing the polysulfide shuttle and enhancing the redox kinetics of sulfur species. The disordered structure of the electrocatalysts exhibits significantly enhanced catalytic activity.

Pseudomonas aeruginosa is a prominent opportunistic pathogen, especially in burn wound infections, and is often associated with high morbidity and mortality due to its multidrug resistance (MDR) characteristics.This study aimed to evaluate the multidrug resistance profile and perform a molecular phylogenetic analysis of P. aeruginosa isolates recovered from human burn infection sample .

Foodborne illnesses pose a significant public health threat globally, particularly in Saudi Arabia, where the rapid growth of the food service sector has increased the risk of exposure to multidrug-resistant (MDR) bacteria. Traditional microbiological methods are often time-consuming and may lack precision, highlighting the need for faster and more accurate diagnostic alternatives. In this study, Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) was employed for the rapid and precise identification of bacterial contaminants in ready-to-eat (RTE) foods, alongside an assessment of their antibiotic resistance profiles.

Primary cardiac lymphoma (PCL) is one of the rarest primary malignancies of the heart. This report describes a rare presentation of diffuse large B-cell lymphoma (DLBCL) in a 61-year-old woman from Iran who presented with weakness, dyspnea, and bilateral lower extremity edema, especially on the right side that progressively worsened over 2 years. Initial diagnostic workup, including laboratory tests, color Doppler ultrasound, and echocardiography, revealed a large immobile mass attached to the RA wall.

Primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT), is an uncommon and aggressive subtype of cutaneous B-cell lymphoma, typically affecting elderly women and predominantly involving the lower extremities. Its diagnosis relies on immunohistochemical profiling and clinical presentation. We report a rare case of a 45-year-old male presenting initially with scalp and supraciliary plaques.
