Binge eating behaviours are associated with recurrent weight gain after metabolic and bariatric surgery.

Background: Recurrent weight gain (RWG) is a major post-operative challenge among metabolic and bariatric surgery (MBS) patients. Binge eating behaviours (BEB) and food addiction (FA) have been identified as significant predictors of post-MBS RWG. However, limited research has investigated their independent associations with post-MBS RWG.

Endothelial TRIM35-Regulated MMP10 Release Exacerbates Calcification of Vascular Grafts.

Vascular calcification is a highly regulated process in cardiovascular disease (CVD) and is strongly correlated with morbidity and mortality, especially in the adverse stage of vascular remodeling after coronary artery bypass graft surgery (CABG). However, the pathogenesis of vascular graft calcification, particularly the role of endothelial-smooth muscle cell interaction, is still unclear. To test how ECs interact with SMCs in artery grafts, single-cell analysis of wild-type mice is first performed using an arterial isograft mouse model and found robust cytokine-mediated signaling pathway activation and SMC proliferation, together with upregulated endothelial tripartite motif 35 (TRIM35) expression.

Not enough: Medicaid expansion, medical debt, and cost avoidance in rural American Indian and Alaska Native households.

Purpose: Despite expanding health insurance coverage under the Patient Protection and Affordable Care Act (ACA), many Americans struggle with financial barriers to health care. Medicaid expansion was meant to help alleviate these barriers, particularly for rural communities, but has shown mixed results. The American Indian and Alaska Native (AI/AN) community, which faces both racial and geographic disparities, is a group that should benefit from Medicaid expansion.

Repression of PFKFB3 sensitizes ovarian cancer to PARP inhibitors by impairing homologous recombination repair.

Background: Ovarian cancer (OC), particularly high-grade serous ovarian carcinoma (HGSOC), is the leading cause of mortality from gynecological malignancies worldwide. Despite the initial effectiveness of treatment, acquired resistance to poly(ADP-ribose) polymerase inhibitors (PARPis) represents a major challenge for the clinical management of HGSOC, highlighting the necessity for the development of novel therapeutic strategies. This study investigated the role of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3), a pivotal regulator of glycolysis, in PARPi resistance and explored its potential as a therapeutic target to overcome PARPi resistance.

Kinematic Alignment Compared with Mechanical Alignment Techniques Results in Greater Peak Three-Dimensional Knee Joint Moments During Stair Negotiation.

Background: This study investigated the influence of surgical alignment techniques on knee joint biomechanics during stair negotiation tasks. Our hypothesis was that a more personalized joint alignment would result in reduced medial knee loading biomechanics to negotiate the stairs.

Methods: There were 28 adults (14 mechanical alignments [MA], 14 kinematic alignment [KA]) who underwent total knee arthroplasty (TKA) at least one year post-operatively and performed five stair ascent and descent trials at their preferred velocities.

Immunology of Biliary Atresia.

Biliary atresia is a progressive neonatal cholangiopathy that leads to liver failure. Characterized by inflammation-mediated liver injury, the immune system plays a critical role in the pathogenesis of this disease. Though several types of immune cells and mediators have been implicated in animal models of biliary atresia, emerging literature reflects the complex interplay of components of the immune response that contributes to disease progression in humans.

Expression and correlation analysis of VISTA in peripheral blood mononuclear cells of myasthenia gravis patients.

Myasthenia gravis (MG) is a T cell-dependent, B cell-mediated disorder strongly associated with antigen presentation by dendritic cells (DCs). In MG, mucosal tolerance is linked to increased expression of TGF-β mRNA in monocytes. Additionally, monocytic myeloid-derived suppressor cells (M-MDSCs) exhibit negative immunomodulatory effects by suppressing autoreactive T and B cells.

Ambient coarse particulate matter pollution and hospital admissions for schizophrenia.

Objective: To investigate the association between ambient coarse particulate matter (PM) pollution and risk of acute schizophrenia episodes.

Methods: A time-stratified case-crossover study with a two-stage analytical approach was conducted to investigate the association between ambient PM pollution and schizophrenia admissions (an indicator for acute schizophrenia episodes) across 259 Chinese cities of prefecture-level or above during 2013-2017. A conditional logistic regression model was constructed to estimate city-specific changes in hospital admissions for schizophrenia associated with per interquartile range (IQR) increase in ambient PM, and the overall associations were obtained by pooling the city-specific associations using the random-effects model.

Setting standards for brain collection procedures in metabolomic studies.

Current metabolomics technologies can measure hundreds of chemical entities in tissue extracts with good reliability. However, long-recognized requirements to halt enzyme activities during the initial moments of sample preparation are usually overlooked, allowing marked postmortem shifts in levels of labile metabolites representing diverse pathways. In brain many such changes occur in a matter of seconds.

HP1 Promotes the Centromeric Localization of ATRX and Protects Cohesion by Interfering Wapl Activity in Mitosis.

Background: α thalassemia/mental retardation syndrome X-linked (ATRX) serves as a part of the sucrose nonfermenting 2 (SNF2) chromatin-remodeling complex. In interphase, ATRX localizes to pericentromeric heterochromatin, contributing to DNA double-strand break repair, DNA replication, and telomere maintenance. During mitosis, most ATRX proteins are removed from chromosomal arms, leaving a pool near the centromere region in mammalian cells, which is critical for accurate chromosome congression and sister chromatid cohesion protection.

Melanoma-derived versican reactivates tumor-associated macrophages by upregulating pyruvate carboxylase through TLR2-MyD88-RelB axis under normoxia.

Relieving hypoxia in the tumor microenvironment (TME) promotes innate and adaptive immunity. Our previous research demonstrated that reoxygenation of the TME promotes the phagocytosis and tumor-killing functions of tumor-associated macrophages (TAMs) by upregulating pyruvate carboxylase (PCB). However, the mechanism remains obscure.

Emerging Roles of TRIM56 in Antiviral Innate Immunity.

The tripartite-motif protein 56 (TRIM56) is a RING-type E3 ubiquitin ligase whose functions were recently beginning to be unveiled. While the physiological role(s) of TRIM56 remains unclear, emerging evidence suggests this protein participates in host innate defense mechanisms that guard against viral infections. Interestingly, TRIM56 has been shown to pose a barrier to viruses of distinct families by utilizing its different domains.

eEF-2K Deficiency Boosts the Virus-Specific Effector CD8 T Cell Responses During Viral Infection.

In this study, we revealed a critical role of eukaryotic elongation factor-2 kinase (eEF-2K), a negative regulator of protein synthesis, in regulating T cells during vaccinia virus (VACV) infection. We found that eEF-2K-deficient (eEF-2K⁻/⁻) mice exhibited a significantly higher proportion of VACV-specific effector CD8 T cells without compromising the development of VACV-specific memory CD8 T cells. RNA sequencing demonstrated that eEF-2K⁻/⁻ VACV-specific effector CD8 T cells had enhanced functionality, which improves their capacity to combat viral infection during the effector phase.
