Background: ω-3 polyunsaturated fatty acids (PUFAs), such as eicosapentaenoic acid (EPA, C20:5ω3) and docosahexaenoic acid (DHA, C22:6ω3), are widely regarded as cardioprotective. EPA, but not DHA, has been reported to prevent fibrosis in heart failure. The relationship between the ω-3 PUFA fraction in epicardial adipose tissue (EAT) and subcutaneous adipose tissue (SAT) and vascular inflammation in patients with cardiovascular disease remains unclear.

Previous research has focused on the lateral-to-anteroposterior tracheal diameter ratio (LAR). This study aimed to assess the LAR and postoperative outcomes of EA patients.
View Article and Find Full Text PDFAcute respiratory distress syndrome (ARDS) is a life-threatening lung injury that induces cytokine hypersecretion. Receptor activity-modifying protein (RAMP) 1, a subunit of the calcitonin gene-related peptide (CGRP) receptor, regulates the production of cytokines. This study examined the role of RAMP1 signaling during lipopolysaccharide (LPS)-induced acute lung injury (ALI).

Although recent studies have identified various factors involved in modifying contractile proteins and mitochondrial function, the molecular mechanisms coordinating contractile and metabolic functions during muscle fiber transition are not fully understood. Using a gene-deficient mouse approach, our previous studies uncovered that vestigial-like family member 2 (Vgll2), a skeletal muscle-specific transcription cofactor activated by exercise, is essential for fast-to-slow adaptation of skeletal muscle.

View Article and Find Full Text PDFAcute lung injury (ALI) is characterized by hyperinflammation followed by vascular leakage and respiratory failure. Vascular endothelial growth factor (VEGF)-A is critical for capillary permeability; however, the role of VEGF receptor 1 (VEGFR1) signaling in ALI progression remains unclear. Here, we show that deletion of VEGFR1 tyrosine kinase (TK) signaling in mice exacerbates lipopolysaccharide (LPS)-induced ALI as evidenced by excessive pro-inflammatory cytokine production and interleukin(IL)-1β-producing neutrophil recruitment to inflamed lung tissues.

Angiogenesis is crucial for the repair and regeneration of liver tissue post-PHx. Calcitonin gene-related peptide (CGRP) released from sensory nerves and its receptor-receptor activity-modifying protein 1 (RAMP1) are involved in angiogenesis.

The association between saltiness perception and sodium intake among CKD patients is unclear, and the factors that influence saltiness are also not fully understood. We evaluated saltiness perception in CKD patients employing a cost-effective saltiness perception test using sodium solutions and evaluated the association between saltiness perception, sodium intake, and the influencing factors.

Background: Craniosynostosis, a common congenital anomaly, results from premature fusion of the cranial sutures. One of the forms of craniosynostosis is premature fusion of the metopic suture, referred to as trigonocephaly, but the diagnosis of metopic suture synostosis remains controversial. The purpose of this study was to clarify, using geometric morphometric analysis, if a metopic ridge alone observed in cases of mild trigonocephaly represents a pathological phenomenon.

Off-the-job training (OJT), especially when using disease-specific models, is an effective method of acquiring surgical skills. To achieve effective OJT, it is necessary to provide objective and appropriate skill assessment feedback to trainees.

This study aims to explore the association between sedentary time and work engagement among workers in Japan in the post-pandemic work environment. Methods This cross-sectional analysis utilized data from the Japan COVID-19 and Society Internet Survey (JACSIS), conducted from September to November 2023, after the COVID-19 pandemic period.

We investigated the potential usefulness and clinical relevance of LAS to detect atrial remodeling including fibrosis by analyzing gene expression in cardiovascular surgery patients. Preoperative 2DSTE was performed in 131 patients (92 patients with sinus rhythm [SR] patients including paroxysmal AF [PAF], 39 atrial fibrillation [AF]) undergoing cardiovascular surgery.

However, immune-related adverse events (irAEs) must be addressed to maximize the efficacy of ICIs. Mycobacterium tuberculosis (Mtb) infection is considered as a type of irAE associated with ICIs, but the underlying mechanism is not completely understood.

However, the details of the interplay between GaN and Mg have remained largely unknown. Here we observe that Mg-intercalated GaN superlattices can form spontaneously by annealing a metallic Mg film on GaN at atmospheric pressure.
