Apoptosis has important pathophysiological consequences contributing to pulmonary arterial hypertension (PAH). However, the mechanism underlying apoptosis in PAH remains unknown. Apoptosis repressor with caspase recruitment domain (ARC) is an essential factor in cell apoptosis, and regulates intrinsic and extrinsic apoptosis signaling pathways. It is hypothesized that ARC may be involved in the apoptotic responses of pulmonary arterial smooth muscle cells (PASMCs) following mild chronic injury. In the present study, serum deprivation (SD) was used to induce apoptosis of PASMCs...

Systemic sclerosis (SSc) is an autoimmune disease characterized by excessive extracellular matrix deposition in the skin and internal organs. Three major abnormalities, autoimmunity, vasculopathy, and fibrosis, are considered to play important roles in the pathophysiology of SSc. SSc is a heterogeneous disease with clinical features, disease progress, therapeutic response, and prognosis. Therefore, identification of biomarkers, which can predict the course of the disease, is required for the progress of clinical practice...

The up-regulation of transient receptor potential channel 6 (TRPC6) has been found to contribute to the proliferation of pulmonary artery smooth muscle cells (PASMCs), and inhibition of phosphodiesterase-5 (PDE5) has been shown to suppress TRPC6 expression in PASMCs. However, the molecular mechanisms underlying the up-regulation of TRPC6 expression and PDE5 modulation of TRPC6 expression in PASMCs remain largely unclear. The aim of this study is to address these issues. Endothelin-1 (ET-1) dose and time-dependently up-regulated TRPC6 expression in primary cultured rat PASMCs, and this was accompanied with the activation of calcineurin and subsequent translocation of NFATc4 to the nucleus...

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease in which the amount of emphysema and airway disease may be very different between individuals, even in end-stage disease. Emphysema formation may be linked to the involvement of the small pulmonary vessels. The NAPDH oxidase (Nox) family is emerging as a key disease-related factor in vascular diseases, but currently its role in hypoxia-induced pulmonary remodelling in COPD remains unclear.Here we investigate the role of p22phox, a regulatory subunit of Nox, in COPD lungs, hypoxic pulmonary vasoconstriction (HPV), hypoxia-induced pulmonary vascular remodelling and pulmonary hypertension...

BACKGROUND: Aspecific scoring systems are used to predict the risk of death postsurgery in patients with infective endocarditis (IE). The purpose of the present study was both to analyze the risk factors for in-hospital death, which complicates surgery for IE, and to create a mortality risk score based on the results of this analysis. METHODS AND RESULTS: Outcomes of 361 consecutive patients (mean age, 59.1±15.4 years) who had undergone surgery for IE in 8 European centers of cardiac surgery were recorded prospectively, and a risk factor analysis (multivariable logistic regression) for in-hospital death was performed...

We have established that annexin A2 (ANXA2) is an important factor in the experimental hepatopulmonary syndrome (HPS) serum-induced proliferation of pulmonary arterial smooth muscle cells (PASMCs). However, the detailed mechanism remains unclear. ANXA2 translocated to the caveolin-enriched microdomains (caveolae) in PASMCs upon HPS serum stimulation. The disruption of caveolae by Methyl-β-cyclodextrin (MβCD) alleviated the caveolae recruitment of ANXA2 and the ANXA2-mediated activation of ERK1/2 and NF-κB, so that ANXA2-modulated PASMC proliferation was suppressed...

Crohn's disease and ulcerative colitis are the two major types of inflammatory bowel disease, and affect mainly the gastrointestinal tract but also have extraintestinal sequelae, such as arterial and venous thromboembolism. Thromboembolic complications, particularly pulmonary thromboembolism, can be life threatening and require prompt management with anticoagulants. Conventional vitamin K antagonists have been used for the treatment of thromboembolic complications, but the development of novel oral anticoagulants has shifted the paradigm...

BACKGROUND: Adult patients with undiagnosed atrial septal defect (ASD) may have right heart cavity enlargement and functional tricuspid valve insufficiency. Moderate or more severe tricuspid regurgitation has been associated with a worse prognosis, and more serious complications are typically seen in older patients. This study aimed to evaluate the improvement in functional tricuspid regurgitation and heart geometry after transcatheter ASD closure in older patients. PATIENTS AND METHODS: The data of 111 patients over 60 years of age with moderate or severe tricuspid regurgitation before ASD closure were analyzed...

We describe the case of a neonate who was prenatally diagnosed at a gestational age of 36 weeks with premature constriction of the ductus arteriosus. Blood from the thin ductus arteriosus flowed toward the pulmonary artery. Severe tricuspid regurgitation was also observed. We subsequently confirmed rupture of the tricuspid papillary muscle after birth. Cardiotonic drugs and nitric oxide were administered immediately at birth for pulmonary hypertension, and this therapy was continued until the seventh postnatal day...

Intraperitoneal free air (IFA) is sometimes accompanied by pneumatosis cystoides intestinalis (PCI); therefore, proper diagnosis is essential for PCI management. We report two cases of PCI with IFA. A 70-year-old female taking anti-psychotic medication for schizophrenia presented with repeated vomiting and high-grade fever. Computed tomography revealed small, linear gaseous cysts in the intestinal wall along with IFA. Although there was no sign of peritoneal irritation, intestinal perforation was not excluded...
