Atrial fibrillation (AF) is commonly associated with heart failure. A bidirectional relationship exists between the two-AF exacerbates heart failure causing a significant increase in heart failure symptoms, admissions to hospital and cardiovascular death, while pathological remodeling of the atria as a result of heart failure increases the risk of AF. A comprehensive understanding of the pathophysiology of AF is essential if we are to break this vicious circle. In this review, the latest evidence will be presented showing a fundamental role for calcium in both the induction and maintenance of AF...

Staphylococcus aureus infection is one of the leading causes of morbidity in hospitalized patients in the United States, an effect compounded by increasing antibiotic resistance. The secreted agent hemolysin alpha toxin (Hla) requires the receptor A Disintegrin And Metalloproteinase domain-containing protein 10 (ADAM10) to mediate its toxic effects. We hypothesized that these effects are in part regulated by Notch signaling, for which ADAM10 activation is essential. Notch proteins function in developmental and pathological angiogenesis via the modulation of key pathways in endothelial and perivascular cells...

Purpose: Portal vein thrombosis (PVT) is one of the severe complications of hepatocellular carcinoma (HCC). PVT deteriorates the liver, and its dysfunction increases the risk of bleeding, influencing the prognosis of patients with liver cirrhosis and HCC. The aim of our study was to investigate whether D-dimer testing could be a sensitive marker for the diagnosis and prognosis of HCC patients with PVT. Patients and methods: Between June 2010 and December 2015, 118 HCC patients were admitted to Cannizzaro Hospital, Catania, and 50 controls were recruited from their relatives for health examinations...

Flavonoids from Huangqin (dried roots of Scutellaria baicalensis Georgi) have anti-inflammatory effects, and are considered useful for treatment of spinal cord injury. To verify this hypothesis, the T9-10 spinal cord segments of rats were damaged using Allen's method to establish a rat spinal cord injury model. Before model establishment, Huangqin flavonoid extraction (12.5 g/kg) was administered intragastrically for 1 week until 28 days after model establishment. Methylprednisolone (30 mg/kg) was injected into the tail vein at 30 minutes after model establishment as a positive control...

We previously demonstrated that administering 2-(2-benzofuranyl)-2-imidazolin (2-BFI), an imidazoline I2 receptor agonist, immediately after ischemia onset can protect the brain from ischemic insult. However, immediate administration after stroke is difficult to realize in the clinic. Thus, the therapeutic time window of 2-BFI should be determined. Sprague-Dawley rats provided by Wenzhou Medical University in China received right middle cerebral artery occlusion for 120 minutes, and were treated with 2-BFI (3 mg/kg) through the caudal vein at 0, 1, 3, 5, 7, and 9 hours after reperfusion...

Described herein is a variant of surgical reconstruction performed in a male patient with a retroaortic position of the left renal vein by means of creating a vein-allograft-vein configuration. Unfortunately, to date, there are no generally accepted recommendations on proper treatment of patients presenting with similar pathology. A situation wherein it is impossible to create an intervenous anastomosis (because of a significantly altered portion of the vein and prestenotic dilataion) dictates the necessity of searching for new variants of surgical management...

The problem of chronic venous insufficiency in women during pregnancy is of current concern. A total of 115 pregnant women in the first, second and third trimesters of gestation were examined in a stage-wise manner. During the first stage we conducted a comprehensive clinical study with the obligatory consultation by the obstetrician-gynaecologist. At the second stage, all women were subjected to ultrasonographic examination of the venous system of both lower extremities and the small pelvis. Studying the diameters of the deep veins of the right and left lower limbs, as well as the paired veins of the small pelvis demonstrated no statistically significant differences, which made it possible to evaluate these parameters as a whole...

Background: Methionine aminopeptidase 2 (MetAP2) cleaves the initiator methionine from nascent peptides during translation. In both preclinical and clinical studies, the pharmacological inhibition of MetAP2 in obese subjects results in the suppression of food intake and body weight loss. However, the mechanism of action of body weight loss caused by MetAP2 inhibition remains to be elucidated, and the sites of action by pharmacological MetAP2 inhibition remain unknown. Methods: In the present study, a comprehensive analysis of the MetAP2 expression pattern in mice was performed...

Neurocysticercosis (NCC) is a helminth infection affecting the central nervous system caused by the larval stage (cysticercus) of Taenia solium. Since vascular alteration and blood-brain barrier (BBB) disruption contribute to NCC pathology, it is postulated that angiogenesis could contribute to the pathology of this disease. This study used a rat model for NCC and evaluated the expression of two angiogenic factors called vascular endothelial growth factor (VEGF-A) and fibroblast growth factor (FGF2). Also, two markers for BBB disruption, the endothelial barrier antigen and immunoglobulin G, were evaluated using immunohistochemical and immunofluorescence techniques...

Vascular endothelial cells (ECs) and smooth muscle cells (VSMCs) are constantly exposed to hemodynamic forces in vivo, including flow shear stress and cyclic stretch caused by the blood flow. Numerous researches revealed that during various cardiovascular diseases such as atherosclerosis, hypertension, and vein graft, abnormal (pathological) mechanical forces play crucial roles in the dysfunction of ECs and VSMCs, which is the fundamental process during both vascular homeostasis and remodeling. Hemodynamic forces trigger several membrane molecules and structures, such as integrin, ion channel, primary cilia, etc...
