Identification and characterization of ethR and ethA genes impacting the sensitivity of Mycobacterium abscessus to ethionamide

ABSTRACT Mycobacterium abscessus is a rapidly growing non-tuberculous mycobacterium with rising global incidence. This pathogen exhibits intrinsic resistance to most antibiotics, presenting a major public health threat. Ethionamide (ETH) requires bioactivation by monooxygenase Et...

Long‐term efficacy of adjunctive cenobamate: Open‐label extension of a randomized, placebo‐controlled study in a multinational Asian population

OBJECTIVE: This study was undertaken to assess long-term efficacy, safety, and tolerability of adjunctive cenobamate in an open-label extension (OLE) of a randomized, double-blind, placebo-controlled, dose-response study (NCT04557085; YKP3089C035 [Study C035]) in Asian patients w...

Spatial distribution, clustering patterns, and economic burden of comorbidities among hospitalised pulmonary tuberculosis patients in Guangdong province: a spatial epidemiological study based on inpatient big data

Background: Comorbidities may complicate the treatment of pulmonary tuberculosis and exacerbate both the clinical and economic burden. We aimed to examine comorbidity patterns, spatial clustering, and economic burden in hospitalised pulmonary tuberculosis (PTB) patients in Guangd...

Selective Similarity Preference: People with a “Darker Core” Desire More Partner Similarity in Dark Traits but Not in Big Five

Research on assortative mating has shown that couples share strong similarities in demographic and attitudinal variables, while the similarity in personality is generally weak. However, a recent meta-analysis indicated that couple similarity in dark traits is considerably greater...

A necroptotic-to-apoptotic signaling axis underlies inflammatory bowel disease

ABSTRACT Inflammatory bowel disease (IBD) is a chronic condition caused by altered cytokine signaling, maladaptive immunity, dysbiosis, and intestinal barrier dysfunction. Patients with IBD receive therapy to correct these imbalances and achieve remission. However, most patients...

Dibutyl phthalate disrupts ESR1-GPX4 redox signaling and aggravates ovarian dysfunction in a PCOS-like mouse model

Dibutyl phthalate (DBP), a widely used phthalate plasticizer, has been implicated in reproductive toxicity, but the molecular mechanisms by which experimental DBP exposure affects ovarian granulosa-cell function remain incompletely defined. In an exploratory clinical cohort, urin...

Sequential Integration of Microenvironment Regulation Utilizing Aggregation‐Induced Emission Luminogen‐Based Carbon Dots for Diabetic Wound Treatment

Effective management of diabetic wound healing remains challenging due to the complex wound microenvironment, characterized by persistent infections and inflammation, as well as obstacles in tissue repair, including impaired extracellular matrix (ECM) remodeling and re-epithelial...

Plasma metabolomic signatures enable the diagnosis and prognosis of chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a progressive heterogeneous lung disease driving global illness and death, yet reliable biomarkers for its early diagnosis, molecular subtyping and prognosis are lacking. Here, we conduct targeted plasma metabolomic profiling in two...

Mapping the senescent stromal landscape and altered the immune microenvironment in PCOS endometrium

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder affecting approximately 10% of reproductive-aged women and is a major cause of infertility. Inadequate endometrial receptivity is a pivotal contributor to this infertility, but its underlying cellular mechanisms r...

Tumor–host metabolic interactions in the microenvironment and macroenvironment: Mechanisms and targeting strategies

ABSTRACT: Tumor metabolic reprogramming is a hallmark of cancer and is driven not only by intrinsic mechanisms of tumor cells but also by dynamic interactions between the local tumor microenvironment (TME) and the host macroenvironment. This review systematically elaborates on th...

IS 26 -mediated circular bla KPC transposon in ST2483 Pseudomonas aeruginosa

ABSTRACT The global spread of carbapenem-resistant Pseudomonas aeruginosa (CRPA) poses a critical clinical threat, with bla KPC as a key mobile carbapenem resistance gene. Here, we investigated a novel bla KPC-2 genetic element and its transmission in clinical ST2483 isolate PA10...

A large-scale multi-center analysis reveals that HNRNPA2B1 variants increase neuroblastoma risk in Chinese children

Neuroblastoma has significant clinical heterogeneity, more precise genetic biomarkers are needed for early risk stratification. Although m 6 A modification has been reported to affect tumor development, the epidemiological impact of HNRNPA2B1 polymorphisms on neuroblastoma suscep...

P1.073. The Evaluative Value of Quality of Life in Neoadjuvant Treatment for Esophageal Squamous Cell Carcinoma

Abstract Topic Esophageal Cancer: Adjuvant and Neo-Adjuvant Therapies Background While neoadjuvant therapy contribute to tumor downstaging and improves resectability rates, effective tools for predicting treatment response remain limited. This study investigated quality of life b...

P1.059. Calcium-Channel Blocker Use and Survival After Neoadjuvant Therapy for Locally Advanced ESCC

Abstract Topic Esophageal Cancer: Adjuvant and Neo-Adjuvant Therapies Background Calcium-channel blockers (CCBs) are commonly prescribed for cardiovascular disease. Beyond hemodynamic effects, experimental studies suggest that CCBs may modulate tumor biology through interference...

P1.057. Early Recurrence After Neoadjuvant Therapy and Esophagectomy for Locally Advanced ESCC

Abstract Topic Esophageal Cancer: Adjuvant and Neo-Adjuvant Therapies Background Despite improved interventions with radical esophagectomy accompanied by perioperative systematic therapy, recurrence remains frequent in locally advanced esophageal squamous cell carcinoma (ESCC). A...

P1.058. Angiotensin System Inhibitors and Outcomes After Neoadjuvant Therapy for Locally Advanced ESCC

Abstract Topic Esophageal Cancer: Adjuvant and Neo-Adjuvant Therapies Background Renin angiotensin system signaling has been implicated in tumor growth, angiogenesis, immune modulation, and responses to cytotoxic and radiation-based therapies, yet clinical effects appear heteroge...

Machine Learning‐Triggered Auto‐Discovery and Promotion of Luminescent Materials: From Predictive Modeling to Autonomous Laboratories

ABSTRACT Machine learning (ML) is transforming the development of luminescent materials, including quantum dots, rare‐earth‐doped phosphors, and transition‐metal‐doped phosphors, by addressing the limitations inherent in traditional trial‐and‐error methodologies. First‐generation...

Epithelial–mesenchymal transition in carcinoma: navigating phenotypic states to target resistance and metastasis

Epithelial–mesenchymal transition (EMT), historically described as a binary morphological change from an epithelium to a mesenchymal state, no longer adequately accounts for carcinoma cell phenotypes observed in patients. Single-cell sequencing, spatial-omics, and lineage tracing...

Benzo[a]pyrene-induced METTL3 overexpression accelerates renal cell carcinoma progression via m6A modification of LTB4R mRNA and enhanced Treg infiltration

Benzo[ a ]pyrene (BaP) is a widespread environmental pollutant and a representative polycyclic aromatic hydrocarbon with well-established carcinogenic properties. However, the molecular mechanisms through which BaP promotes renal cell carcinoma (RCC) progression, particularly tho...

Motor imagery enhances swallowing motor cortex excitability and activates sensorimotor regions: a TMS and fNIRS study

Action observation (AO) and motor imagery (MI) represent promising, non-invasive strategies for promoting neuroplasticity in motor rehabilitation by engaging the shared neural substrates of actual movement. However, their translation to swallowing rehabilitation, particularly for...
