Halomonas pelophila sp. nov., isolated from mud and Halomonas aquatica sp. nov., isolated from marine water.

Two Gram-negative, catalase- and oxidase-positive, cream-coloured, short rod-shaped, and motile bacterial strains, designated CS7 and SSM6, were isolated from mud and marine water collected in Incheon, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences showed that both strains belonged to the genus Halomonas. Strain CS7 exhibited the highest 16S rRNA similarity with Halomonas urmiana TBZ3 (99.

Analysis of lymph node metastasis based on consolidation tumor ratio and maximum standardized uptake value in clinical stage IA non-small cell lung cancer.

Background: Sublobar resection has been established as an acceptable treatment for early-stage non-small cell lung cancer (NSCLC). As a result, preoperative prediction of lymph node (LN) metastasis is becoming an important factor in determining surgical strategy. This study aimed to investigate the predictive accuracy of the consolidation tumor ratio (CTR) and the maximum standardized uptake value (maxSUV) of the primary tumor for LN metastasis in patients with clinical stage IA NSCLC.

Heavy metals promote the formation of multidrug-tolerant Staphylococcus aureus and Escherichia coli persisters.

Bacterial persisters are dormant phenotypic variants that are tolerant to antibiotics, contributing to treatment failure and the emergence of antimicrobial resistance. Although the formation of persisters has been extensively studied in regards to bacterial infections and treatment, such as antibiotic exposure or intracellular survival within macrophages, the role of environmental stressors in persister formation remains largely unexplored. In this study, we investigate the role of environmental heavy metals, specifically arsenic (As), cadmium (Cd), and mercury (Hg), in promoting persister cell formation in Staphylococcus aureus and Escherichia coli.

Dual-MOF-Layered Films via Solution Shearing Approach: A Versatile Platform for Tunable Chemiresistive Sensors.

Metal-organic frameworks (MOFs) are ideal for gas sensing due to their high porosity and chemical diversity. However, their low electrical conductivity has traditionally limited their application in chemiresistive-type sensors. The recent development of electrically conductive MOFs (cMOFs) has addressed this limitation.
