Preserved ratio impaired spirometry, airflow obstruction, and their trajectories in relationship to chronic kidney disease: a prospective cohort study.

Spirometry findings, such as restrictive spirometry and airflow obstruction, are associated with renal outcomes. Effects of spirometry findings such as preserved ratio impaired spirometry (PRISm) and its trajectories on renal outcomes are unclear. This study aimed to investigate the impact of baseline and trajectories of spirometry findings on future chronic kidney disease (CKD) events.

Plasma membrane-associated ARAF condensates fuel RAS-related cancer drug resistance.

RAF protein kinases are major RAS effectors that function by phosphorylating MEK. Although all three RAF isoforms share a conserved RAS binding domain and bind to GTP-loaded RAS, only ARAF uniquely enhances RAS activity. Here we uncovered the molecular basis of ARAF in regulating RAS activation.

Stromal architecture and fibroblast subpopulations with opposing effects on outcomes in hepatocellular carcinoma.

Dissecting the spatial heterogeneity of cancer-associated fibroblasts (CAFs) is vital for understanding tumor biology and therapeutic design. By combining pathological image analysis with spatial proteomics, we revealed two stromal archetypes in hepatocellular carcinoma (HCC) with different biological functions and extracellular matrix compositions. Using paired single-cell RNA and epigenomic sequencing with Stereo-seq, we revealed two fibroblast subsets CAF-FAP and CAF-C7, whose spatial enrichment strongly correlated with the two stromal archetypes and opposing patient prognosis.

Cross-Cultural Adaptation and Validation of the Mandarin Chinese Version of the Vocal Performance Questionnaire.

Objective: The Mandarin Chinese version of the Vocal Performance Questionnaire (VPQ-CM) for evaluating vocal performance.

Methods: A total of 120 participants with vocal disorders and 120 healthy participants completed this study. Investigators translated the original VPQ into the VPQ-CM, and participants completed the questionnaire fill it.

Development and therapeutic assessment of bispecific nanobodies targeting B-cell activating factor and interleukin-17 for the neutralization of inflammatory mediators in autoimmune diseases.

Autoimmune diseases are characterized by dysregulated immune responses and chronic inflammation. B cell activating factor (BAFF) and interleukin-17 (IL-17) are key mediators in the pathogenesis of several autoimmune diseases, driving B cell hyperactivation, autoantibody production, and tissue damage. Simultaneous targeting of these pathways may provide a synergistic therapeutic approach.
