There is lately observed an increase in the resistance of the main pathogens of urologic infection to β-lactam antibiotics due to production of plasmid-induced β-lactamases. The aim of the study was to reveal types TEM, SHV and CTX-M plasmid β-lactamases among uropathogens. Out of 115 isolates, 30 (26.1%) strains produced β-lactamases. Genes blaTEM and bla CTX-Mwere the most frequent. Most of the isolates were resistant to ampicillin (73.3%), ciprofloxacin (46.7%), levofloxacin (43.3%), gentamicin (40%). The βLES-producing strains were susceptible to meropenem (96.7%), nitroxolin (83.3%), phosphomycin (70%), amikacin (70%). The presence of the resistance genes in the uropathogens was evident of a high rate of their distribution among them by the plasmids. Detection of the plasmid-induced β-lactamases is important for the optimal choice of the antibiotic for empirical therapy.

Human natural killer (NK) cells can be sub-divided into two functional subsets but the clinical significance of these CD56 and CD56 NK cells in anti-tumour immunity remains largely unexplored. We determined the relative abundances of gene signatures for CD56 and CD56 NK cells along with 3 stromal and 18 other immune cell types in the patient tumour transcriptomes from the cancer genome atlas bladder cancer dataset (TCGA-BLCA). Using this computational approach, CD56 NK cells were predicted to be the more abundant tumour-infiltrating NK subset which was also associated with improved patient prognosis.

Vegetation productivity and ecosystem carbon sink capacity are significantly influenced by seasonal weather patterns. The time lags between changes in these patterns and ecosystem (including vegetation) responses is a critical aspect in vegetation-climate and ecosystem-climate interactions. These lags can vary considerably due to the spatial heterogeneity of vegetation and ecosystems.

The study aimed to compare the effects of different types of excimer laser keratectomy on rabbit corneas and to identify the optimal disease model for corneal ectasia. Additionally, investigating the structural and molecular alterations in the novel disease model helped explore the mechanisms underlying biomechanical cues in corneal ectasia. 2.

The ultrastructural organization of the nuclei of the tegmental region in juvenile chum salmon () was examined using transmission electron microscopy (TEM). The dorsal tegmental nuclei (DTN), the nucleus of (NFLM), and the nucleus of the oculomotor nerve (NIII) were studied. The ultrastructural examination provided detailed ultrastructural characteristics of neurons forming the tegmental nuclei and showed neuro-glial relationships in them.

Objective: The endometrial microbiota exerts a crucial role in maintaining the health of the female reproductive system. As such, in this study, we have examined the composition of the microbiota in endometrium tissues with and without endometriosis, with the objective of identifying key species that may potentially contribute to the progression of endometriosis.
Methods: We obtained endometrial tissues from 43 women diagnosed as either having endometriosis or not.
