Cells perceive the physical cues such as perturbations of extracellular matrix (ECM) stiffness, and translate these stimuli into biochemical signals controlling various aspects of cell behavior, which contribute to the physiological and pathological processes of multiple organs. In this study, we tested the hypothesis that during arterial stiffening, vascular smooth muscle cells (SMCs) sense the increase of ECM stiffness, which modulates the cellular phenotype through the regulation in DNA methyltransferases 1 (DNMT1) expression...

BACKGROUND: The management of massive pulmonary embolism remains challenging, with a considerable mortality rate. Although veno-arterial extracorporeal membrane oxygenation (VA-ECMO) for massive pulmonary embolism has been reported, its use as salvage therapy has been associated with poor outcomes. We reviewed our experience utilizing an aggressive, protocolized approach of VA-ECMO to triage, optimize, and treat these patients. METHODS: All patients with a massive pulmonary embolism who were placed on VA-ECMO, as an initial intervention determined by protocol, were retrospectively reviewed...

BACKGROUND: Radioembolization (RE) with intra-arterial administration of (90)Y microspheres is a promising technique for the treatment of liver metastases from small intestinal neuroendocrine tumors (SI-NET) not amenable to surgery or local ablation. However, studies comparing RE to other loco-regional therapies are lacking. The aim of this randomized study was to compare the therapeutic response and safety after RE and bland hepatic arterial embolization (HAE), and to investigate early therapy-induced changes with diffusion-weighted MRI (DWI-MRI)...

Total robotic resection of mid- and low rectal cancers confers technical advantages within the confines of the pelvis and allows difficult rectal cancer cases to be performed efficiently with less risk of conversion to open. To maximize the advantage of robotic surgery, we utilize the technique of single docking totally robotic dissection for rectal cancer for both the Da Vinci Si and Xi Surgical Systems. All steps are performed robotically, with the surgery divided into two phases. The first phase consists of inferior mesenteric artery and vein ligation, sigmoid and descending colon mobilization and splenic flexure takedown...

Chronic inflammation promotes the development of hypertension and is associated with increased T cell infiltration and cytokine production in impaired organs. Gap junction protein connexin 43 (Cx43), is ubiquitously expressed in immune cells and plays an important role in T cell proliferation and activation, and cytokine production. However, the correlation between Cx43 in T cells and the hypertensive inflammatory response remains unknown. Thus, in this study, we wished to examine this correlation. First, our results revealed that hypertension caused significant thickening of the vascular wall, inflammatory cell infiltration into part of the renal interstitium and glomerular atrophy, and it increased the tubular damage scores in the kidneys of spontaneously hypertensive rats (SHRs)...

AIMS: Oxidative stress and inflammation have been implicated in the pathogenesis of vascular dementia (VD). Thioredoxin-interacting protein (TXNIP) plays a vital role in oxidative stress and NOD-like receptor protein 3 (NLRP3) inflammasome activation. There is evidence that acupuncture has an antioxidative and neuroprotective effect in VD. In this study, we investigated whether acupuncture can attenuate cognitive impairment via inhibiting TXNIP-associated oxidative stress and inflammation in VD rats...

Previous epidemiological studies have suggested that genetic factors are more likely to influence the development of premature coronary artery disease (CAD) than disease in older patients. Several studies have evaluated the association between the G894T polymorphism located in an exon of endothelial nitric oxide synthase (eNOS) and the risk of premature CAD. However, the findings were inconsistent. Thus, we performed a meta-analysis to clarify the association; we conducted both overall and subgroup analyses...

Pulmonary artery anastomosis stenosis is a rare cause of right ventricular failure after orthotopic heart transplantation. In this case report, direct ultrasound of the pulmonary artery helped diagnose stenosis at a location not visible on transesophageal echocardiography or even with standard epicardial ultrasound views. It is important to evaluate all vascular anastomoses after heart or lung transplantation because surgical revision of these lesions is facile, but if left undiagnosed, significant morbidity or mortality is likely...

BACKGROUND: Advanced age is an independent predictor of poor outcome after cardiac arrest (CA). From experimental studies of regional ischemia-reperfusion injury, advanced age is associated with larger infarct size, reduced organ function, and augmented oxidative stress. The objective of this study was to investigate the effect of age on cardiovascular function, oxidative stress, inflammation, and endothelial activation after CA representing global ischemia-reperfusion. METHODS: Aged (26 months) and young (5 months) rats were subjected to 8 min of asphyxia induced CA, resuscitated and observed for 360 min...
