A flow cytometry test was developed to identify carbapenemase production by Enterobacteriaceae and to discriminate between the different types of carbapenemases (classes A, B, and D). It is based on the detection of meropenem activity against bacteria, coupled with different carbapenemase inhibitors, which is assessed by flow cytometry. It represents a convenient, fast, and reliable approach (100% sensitivity and 100% specificity) for the detection and characterization of different carbapenemases.

Introduction: Immunosenescence remodels immune functions and was first described with aging. It is present in 25% of cancer patients but has also been described in patients with Immune-mediated inflammatory diseases (IMIDs). This study aims at quantifying cells exhibiting a phenotype of senescence in CD4+ (T4sen) and CD8+ (T8sen) T cells, analyzing its potential drivers and the effect of anti-TNF treatment in a prospective cohort of patients with rheumatoid arthritis (RA), spondyloarthritis (SpA) and Sjögren disease (SjD).

Objectives: Osteoarthritis (OA) is one of the most common chronic degenerative diseases, with chondrocyte apoptosis and extracellular matrix (ECM) degradation as the major pathological changes. The mechanical stimulation can attenuate chondrocyte apoptosis and promote ECM synthesis, but the underlying molecular mechanisms remain unclear. This study aims to investigate the role of primary cilia (PC) in mediating the effects of mechanical stimulation on OA progression.

Objectives: Acute lung injury (ALI) is an acute respiratory failure syndrome characterized by impaired gas exchange. Due to the lack of effective targeted drugs, it is associated with high mortality and poor prognosis. (TW) has demonstrated anti-inflammatory activity in the treatment of various diseases.

Esophageal cancer is a major cause of cancer-related death, often preceded with chronic inflammation and injuries. The NFκB/IKKβ pathway plays a central role in inflammation, yet its role in early esophageal carcinogenesis remains unclear. This study investigated the role of epithelial IKKβ in early esophageal carcinogenesis.

Objectives: To study the molecular mechanisms of LDH-loaded si-NEAT1 for regulating paclitaxel resistance and tumor-associated macrophage (TAM) polarization in breast cancer.
Methods: qRT-PCR and Western blotting were used to detect the expression of lncRNA NEAT1, miR-133b, and PD-L1 in breast cancer SKBR3 cells and paclitaxel-resistant SKBR3 cells (SKBR3-PR). The effects of transfection with si-NEAT1 and miR-133b mimics on MRP, MCRP and PD-L1 expressions and cell proliferation, migration and apoptosis were investigated using qRT-PCR, Western blotting, scratch and Transwell assays, and flow cytometry.
