Pathogenic intracellular bacteria pose a significant threat to global public health due to the barriers presented by host cells hindering the timely detection of hidden bacteria and the effective delivery of therapeutic agents. To address these challenges, we propose a tandem diagnosis-guided treatment paradigm. A supramolecular sensor array is developed for simple, rapid, accurate, and high-throughput identification of intracellular bacteria.

is a vital zoonotic pathogen known for its extensive drug resistance and ability to form biofilms, which contribute to its antibiotic resistance. In this study, the phage vB_C4, specifically targeting , was isolated and subjected to bioinformatic analysis and bacteriostatic activity assays. The combination of phage vB_C4 with antibiotics such as cephalothin and cefoxitin, which target the bacterial cell wall, resulted in a significantly enhanced bacteriostatic effect compared to either the phage or antibiotics alone.

On the one hand, nature utilizes hierarchical assemblies to create complex biological binding pockets, enabling ultrastrong recognition toward substrates in aqueous solutions. On the other hand, chemists have been fervently pursuing high-affinity recognition by constructing covalently well-preorganized stereoelectronic cavities. The potential of noncovalent assembly, however, for enhancing molecular recognition has long been underestimated.

The trans-translation system, mediated by transfer-messenger RNA (tmRNA, encoded by the gene) and its partner protein SmpB, helps to release ribosomes stalled on defective mRNA and targets incomplete protein products for hydrolysis. Knocking out the and genes in various pathogens leads to different phenotypic changes, indicating that they have both cooperative and independent functionalities. This study aimed to clarify the functional relationships between tmRNA and SmpB in a pathogen that poses threats in aquaculture and human health.

Background: Electroconvulsive therapy (ECT) is a highly effective treatment for schizophrenia and mood disorders; however, most evidence is derived from the adult population, with less evidence in adolescents. We sought to determine the use of ECT in adolescents in the Institute of Mental Health (IMH) and evaluate the treatment outcome.

Methods: We conducted a retrospective naturalistic analysis of ECT registry data of patients aged from 10 to 19 years from March 2017 to March 2023.

The current mortality rates for breast cancer underscore the need for better prognostic tools; moreover, LIM and calponin homology domain 1 (LIMCH1), which is a protein with dual roles in cancer, is a promising candidate for investigation. This study employed an integrative approach combining bioinformatics analysis of The Cancer Genome Atlas (TCGA) cohort and clinical immunohistochemistry (IHC) cohort data. We analysed LIMCH1 expression patterns, its associations with clinicopathological features and prognosis, and its impact on the tumour immune microenvironment (TIME).

Fenton reactions, commonly employed in environmental remediation, decompose H₂O₂ using Fe⁺ to generate free radicals. However, the efficiency is often limited by the slow conversion of Fe³⁺ to Fe⁺. In this study, we synthesize zero-valent iron nanoparticles (nZVI) via a green, plant extract-mediated reduction method, resulting in nZVI coated with a reductive polyphenolic layer that enhances Fe³⁺/Fe⁺ cycling.

Article Synopsis
  • Breast cancer presents a major global health issue, complicated by its diverse characteristics and resistance to treatment, while current staging systems fail to fully represent its biological complexity.
  • This study investigated MyD88, an important protein in inflammatory responses, using advanced techniques like RNA sequencing and immunohistochemistry to examine its role in breast cancer.
  • Elevated MyD88 levels correlated with better patient outcomes and increased sensitivity to chemotherapy, suggesting its potential as a predictive biomarker and a valuable tool for personalized medicine in treating breast cancer.

Article Synopsis
  • Hfq, an RNA chaperone, is crucial for the virulence and pathogenicity of the infectious bacterium Aeromonas veronii.
  • Deleting the hfq gene leads to decreased swimming motility, reduced biofilm formation, and lower adhesion to epithelial cells, significantly impairing its ability to colonize in host tissues.
  • The study indicates that while hfq deletion reduces some virulence traits, it paradoxically increases secreted proteins and cytotoxicity, suggesting Hfq regulates the expression of virulence factors, balancing pathogenicity and fitness in A. veronii.

Flagella are essential for biofilm formation, adhesion, virulence, and motility. In this study, the deletion of argR resulted in defects in flagellar synthesis and reduced motility, nevertheless, the underlying mechanism by which ArgR regulated bacterial motility remained unclear. ChIP-Seq and RNA-Seq analysis revealed that ArgR regulated the expression of flagellar genes, concluding two-component system flrBC and multitudinous flagellar structure genes.

Background: In recent years, the combination of CDK4/6 inhibitors (CDK4/6i) and endocrine therapy (ET) has emerged as the standard first-line treatment for hormone receptor positive (HR+) and human epidermal growth factor receptor 2 negative (HER2-) metastatic breast cancer (MBC) patients. However, the comparison between the efficacy of CDK4/6i has been poorly explored before. Moreover, it remains unclear about the optimal choice of CDK4/6i in the first-line treatment for HR+/HER2- MBC patients in Asian, especially Chinese populations.

Repeated low-intensity noise exposure is prevalent in industrialized societies. It has long been considered risk-free until recent evidence suggests that the temporary threshold shift (TTS) induced by such exposure might be a high-risk factor for hearing loss. This study was conducted to further investigate the manner in which repeated low-intensity noise exposure contributed to hearing damage.

Background: Post-traumatic Fusarium infection is rare. Arterial occlusive disease, a common vascular disorder in the elderly, often leads to ischemic necrosis of the lower extremities, which in turn increases the likelihood of secondary infections. Those secondary infections can be caused by bacteria, virus, or fungi.

: Ferroptosis in lung epithelium and endothelium contributes to the pathogenesis of acute respiratory distress syndrome (ARDS), a critical and often fatal condition marked by acute inflammation and elevated pulmonary vascular permeability. Despite this, there are currently no FDA-approved therapeutics specifically targeting ferroptosis for ARDS management. : A screening of 259 FDA-approved drugs was conducted to identify an effective ferroptosis inhibitor in pulmonary epithelial and endothelial cells.

Cancer cells secrete extracellular vesicles (EV) encapsulating bioactive cargoes to facilitate inter-organ communication in vivo and are emerging as critical mediators of tumor progression and metastasis, a condition which is often accompanied by a dysregulated cholesterol metabolism. Whether EVs are involved in the control of cholesterol homeostasis during tumor metastasis is still undefined and warrant further investigation. Here, we find that breast cancer-derived exosomal miR-9-5p induces the expression of HMGCR and CH25H, two enzymes involved in cholesterol synthesis and the conversion of 25-hydroxycholesterol from cholesterol by targeting INSIG1, INSIG2 and ATF3 genes in the liver.

Background: Improving the microenvironment to augment endogenous regenerative potential has emerged as a fundamental concept for stimulating and expediting periodontal tissue repair and regeneration. Previous studies have demonstrated that TPPU, a soluble epoxide hydrolase inhibitor (sEHi), mediates the suppression of inflammatory bone loss in periodontitis models. However, the underlying mechanisms remain largely elusive.

TANK binding kinase 1 (TBK1) is an important kinase that is involved in innate immunity and tumor development. Macrophage colony-stimulating factor (M-CSF) regulates the differentiation and function of macrophages towards the immunosuppressive M2 phenotype in the glioblastoma multiforme microenvironment. The role of TBK1 in macrophages, especially in regulating macrophage polarization in response to M-CSF stimulation, remains unclear.
