Baseline fibroblast growth factor 23 predicts incident heart failure and cardiovascular mortality in patients with chronic kidney disease: A 3-year follow-up study.

Background: Heart failure (HF) is a significant cause of death among patients with chronic kidney disease (CKD). Emerging data suggest a crucial role of fibroblast growth factor 23 (FGF23) in the pathogenesis of HF in CKD patients. The present study aimed to investigate whether the serum intact FGF23 (iFGF23) level is elevated when ejection fraction (EF) is preserved and to evaluate its predictive value for incident HF and cardiac mortality in CKD patients with preserved EF.

Identification of USP2 as a novel target to induce degradation of KRAS in myeloma cells.

Inducing the degradation of KRAS represents a novel strategy to combat cancers with KRAS mutation. In this study, we identify ubiquitin-specific protease 2 (USP2) as a novel deubiquitinating enzyme of KRAS in multiple myeloma (MM). Specifically, we demonstrate that gambogic acid (GA) forms a covalent bond with the cysteine 284 residue of USP2 through an allosteric pocket, inhibiting its deubiquitinating activity.

The current research status of the mechanisms and treatment of radioactive brain injury.

Radioactive brain injury, a severe complication ensuing from radiotherapy for head and neck malignancies, frequently manifests as cognitive impairment and substantially diminishes patients' quality of life. Despite its profound impact, the pathogenesis of this condition remains inadequately elucidated, and efficacious treatments are notably absent in clinical practice. Consequently, contemporary interventions predominantly focus on symptom alleviation rather than achieving a radical cure or reversing the injury process.

Role of Arg1 ILC2s and ILCregs in gestational diabetes progression.

Innate lymphoid cells (ILCs) are a newly discovered subset of immune cells that are responsible for regulation of the immune microenvironment. In particular, the ILC categories ILC2s and regulatory ILCs (ILCregs) are associated with immunosuppression and chronic inflammation. Chronic low-grade inflammation leads to insulin resistance, a major etiological factor in gestational diabetes mellitus (GDM).

Distinction in the function and microstructure of white matter between major depressive disorder and generalized anxiety disorder.

Background: Major depressive disorder (MDD) and generalized anxiety disorder (GAD) are two of the leading causes of impairment to human mental health. These two psychiatric disorders overlap in many symptoms and neurobiological features thus difficult to distinguish in some cases.

Methods: We enrolled 102 participants, comprising 40 patients with MDD, 32 patients with GAD and 30 matched healthy controls (HCs), to undergo multimodal magnetic resonance imaging (MRI) scans.

Methods: A total of 3053 healthy adults (1922 women) aged 18-79 years were enrolled.

BPZ inhibits early mouse embryonic development by disrupting maternal-to-zygotic transition and mitochondrial function.

The use of Bisphenol A (BPA) has been widely restricted due to its adverse health effects. Bisphenol Z (BPZ) is used as an alternative to BPA, and humans are widely exposed to BPZ through various routes. Recent studies have shown that BPZ exposure adversely affects mouse oocyte meiotic maturation.
