Summary: In this study, a novel biosynthesis method for the preparation of zinc oxide/carbon nanofiber nanocomposite (ZnO-CNFs) was proposed and their photocatalytic and antimicrobial properties were evaluated for wastewater treatment. The synthesized ZnO-CNFs showed high photodegradation efficiency of tetracycline antibiotic residues and superior antibacterial and antifungal activity compared to ZnO nanoparticles. These findings indicate that ZnO-CNFTD exhibits excellent photocatalytic and antimicrobial potential and can be a promising candidate for effective treatment of water contaminated with microorganisms and organic compounds.

Summary: The objective of this study is to identify the receptor that mediates the activity of BacSp222 bacteriocin. Through fluorescent labeling and confocal microscopy, it was found that BacSp222 interacts directly with cells. The results show that BacSp222 binds to TLR2/TLR6 heterodimers and induces proinflammatory signaling through MyD88 and NF-kappa B pathways.

Summary: The fungal pathogen Candida albicans can form biofilms that protect it from drugs and the immune system by releasing extracellular vesicles (EVs) that promote extracellular matrix formation and resistance to antifungal drugs. The study identifies functions for numerous EV cargo proteins in biofilm matrix assembly, drug resistance, fungal cell adhesion, and dissemination. The findings suggest that EVs play a crucial role in coordinating biofilm development in C. albicans.

Summary: This study aimed to identify the active TLR2 heterodimer (TLR2/1 or TLR2/6) involved in sperm-uterine immune crosstalk in bovine. The results revealed that sperm triggered the expression of TLR1 and TLR2 through TLR2/1 heterodimer, and TLR2/6 heterodimer induced a stronger inflammatory response. The findings suggest that sperm utilize TLR2/1 heterodimerization to trigger a weak inflammatory response in the bovine uterus, providing an ideal uterine environment for early embryo reception and implantation.

Summary: Microbial interactions play a crucial role in microbial physiology, with quorum sensing and metabolite exchange being key elements. Loss-of-function mutations in quorum-sensing components are common across different species, and quorum sensing is modulated by small molecules and environmental conditions. Recent evidence suggests that strain heterogeneity can impact microbial interactions and act as selective pressures on the emergence of common mutations in quorum sensing genes.

Summary: The study aimed to determine the epidemiological cut-off values (ECVs) of ten antifungal agents in a wide range of yeasts and Aspergillus spp. using gradient concentration strips. Retrospective collection of minimum inhibitory concentrations for various antifungal agents was done from 35 French microbiology laboratories between 2002 and 2020. The calculated ECVs can aid in interpreting minimum inhibitory concentrations and identifying non-wild type isolates.

Summary: This study assessed the value of beta 1,3-D-glucan (BDG) detection in the cerebrospinal fluid (CSF) of non-neonatal non-cryptococcosis patients. The results showed that the sensitivity of BDG assay in diagnosing proven/highly probable/probable FI-CNS ranged from 72.7% to 100%, and the specificity was found to be 81.8%. Despite its sub-optimal performance, BDG assay should be added to the diagnostic armamentarium for FI-CNS.

Summary: Western diets, high in fat and sugar and low in vegetable fiber, are causing an increase in obesity and diseases of civilization. These diets lead to gut dysbiosis and overgrowth of Candida albicans, a major cause of fungal infection worldwide. Factors such as smoking, excessive alcohol consumption, lack of physical activity, prolonged use of antibiotics, and chronic psychological stress also contribute to disease development and gut dysbiosis. A diversified diet containing vegetable fiber, omega-3 polyunsaturated fatty acids, vitamins D and E, and probiotic or prebiotic supplements can improve the biodiversity of the microbiota and reduce the abundance of fungal species in the gut. Traditional medicine offers various foods and plants effective against fungal overgrowth and gut dysbiosis. Overall, healthy diets and lifestyle factors positively impact the gut microbiota and the brain.

Summary: Mucormycosis is a rare and life-threatening fungal infection caused by molds of the order Mucorales. It mainly affects the lungs, following the rhino-orbito-cerebral (ROC) areas and the skin. Risk factors for pulmonary mucormycosis (PM) include hematological malignancies and solid organ transplantation, while ROC infections are commonly associated with diabetes mellitus. The diagnosis of PM relies on CT scans, cultures, PCR tests, and histology, and treatment involves liposomal amphotericin B as the first-line therapy.

Summary: Cell identity is controlled by a core transcriptional regulatory circuitry (CoRC) consisting of cell-specific transcription factors (TFs). However, our study reveals that the transcriptional regulatory network regulating hepatocyte identity is more complex than initially thought. We identified a set of TFs, which we call hepatocyte identity (Hep-ID)(CONNECT) TFs, that not only control hepatocyte identity effector genes, but also interact with TFs of the CoRC. Furthermore, we found that Hep-IDCONNECT TFs play a role in fine-tuning CoRC TF expression and can reset CoRC TF expression in dedifferentiated hepatocytes.
