Interferon-δ (IFN-δ) belongs to type I IFN. It was first identified by Lefevre in 1993. The porcine interferon-δ (PoIFN-δ)-related sequences were reported in 2009. The IFN-δ-related sequences have not been studied as closely as IFN-α and IFN-β. In this study, we identified 11 functional genes and 7 pseudogenes of the PoIFN-δ-related subtypes from the porcine genome database. Three of these genes were cloned, expressed, and functionally studied. PoIFN-δ-related subtypes can bind to the type I IFN receptors, activate the Janus kinase-signal transduce and activator of transcription (JAK-STAT) signaling pathway, induce IFN stimulate genes, and other cytokines. The antiviral activity of PoIFN-δ-related subtypes varies a lot in different subtypes. Among all the PoIFN-δ subtypes detected, PoIFN-δ8 has the strongest antiviral and immunomodulatory activities.

Background: Tumefactive demyelination (TD) is a rare variant of multiple sclerosis (MS) characterized by tumor-like lesions that often require aggressive management. Genome-wide association studies (GWAS) identified variants associated with MS; similar analyses in TD are lacking.
Objective: A GWAS was performed to identify variants associated with TD.

Background: In response to the opioid epidemic, many surgical specialties have adopted nonopioid pain management strategies. Ultrasound (US)-guided peripheral nerve blocks (PNBs) are effective in reducing pain and opioid consumption postsurgery. Liposomal bupivacaine (LB), shown effective in shoulder surgery, was approved in November 2023 for use in US-guided lower extremity blocks.

Objectives: Patients with connective tissue diseases (CTD) have a high incidence of cardiac involvement, which often presents insidiously and can progress rapidly, making it one of the leading causes of death. Multiparametric cardiovascular magnetic resonance (CMR) provides a comprehensive quantitative evaluation of myocardial injury and is emerging as a valuable tool for detecting cardiac involvement in CTD. This study aims to investigate the correlations between CMR features and serological biomarkers in CTD patients, assess their potential clinical value, and further explore the impact of pre-CMR immunotherapy intensity on CMR-specific parameters, thereby evaluating the role of CMR in the early diagnosis of CTD-related cardiac involvement.

Objectives: Intracranial aneurysm (IA) has an insidious onset, and once ruptured, it carries high rates of mortality and disability. Cardiometabolic factors may be associated with the formation and rupture of IA. This study aims to summarize the application of Mendelian randomization (MR) methods in research on cardiometabolic factors and IA, providing insights for further elucidation of IA etiology and pathogenesis.

Background: This study aimed to investigate the association between adiponectin levels and the incidence of metabolic dysfunction- associated steatotic liver disease (MASLD) and nonalcoholic fatty liver disease (NAFLD), and to explore the predictive value of adiponectin in the onset of these conditions.
Methods: A 17-year follow-up of 35,026 individuals from the Korean Cancer Prevention Study-II biobank cohort (2004-2021) was conducted. Adiponectin levels were categorized into quintiles.
