BACKGROUND: Patients with ruptured saccular intracranial aneurysms have excess long-term mortality due to cerebrovascular and cardiovascular diseases compared with general population. Chronic inflammation is detected in ruptured intracranial aneurysms, abdominal aortic aneurysms and coronary artery plaques. Bacterial infections have been suggested to have a role in the aetiology of atherosclerosis. ...

Plasmodium falciparum utilizes multiple ligand-receptor interactions for invasion. The invasion ligand EBA-175 is being developed as a major blood-stage vaccine candidate. EBA-175 mediates parasite invasion of host erythrocytes in a sialic acid-dependent manner through its binding to the erythrocyte receptor glycophorin A. In this study, we address the ability of ...

Seven three-month-old, female, helminth-free lambs were immunized intranasally with three doses (1 mg total) of a recombinant part of the catalytic region of the serine/threonine phosphatase 2 A (PP2Ar) (G1). In addition, four lambs were used as an adjuvant control group (G2), four as unimmunized, infected controls (G3) and four ...

Patients with pancreatic cancer, which is characterized by an extensive collagen-rich fibrotic reaction, often present with metastases. A critical step in cancer metastasis is epithelial to mesenchymal transition, which can be orchestrated by Snail family of transcription factors. To understand the role of Snail (Snai1) in pancreatic cancer, we generated ...

The incidence of gastric cancer throughout the world is ∼2-3 times higher in men than in women. Previous research suggested that isoflavones, which are structurally similar to 17β-estradiol, may prevent gastric cancer. Based on a large, population-based, prospective study, we recently reported a null association between dietary isoflavone intake and ...

OBJECTIVES: Constrictive pericarditis is the result of a spectrum of primary cardiac and non-cardiac conditions. Few data exist on the preoperative risk specific to survival after pericardiectomy. This study was designed to compare the association of aetiology of constrictive pericarditis and other clinical variables, with long-term survival after total pericardiectomy. ...

Atherosclerosis is accelerated in diabetes mellitus mainly due to the reduced availability and function of endothelial progenitor cells (EPCs). The purpose of this study was to determine the protective effects of the anthocyanin cyanidin-3-O-β-glucoside (C3G) on EPC function and endothelial repair in diabetic apolipoprotein E-deficient (apoE(-/-)) mice. Diabetes mellitus was ...

OBJECTIVES: Patients with chronic Stanford type B aortic dissections (TBAD) are traditionally treated medically, but some of the affected thoracic and thoracoabdominal aortic segments progress to large aneurysms with a significant risk of rupture. The purpose of this study is to retrospectively evaluate, with an 'all-comers' approach, the survival and ...

Many high-level visual regions exhibit complex patterns of stimulus selectivity that make their responses difficult to explain in terms of a single cognitive mechanism. For example, the parahippocampal place area (PPA) responds maximally to environmental scenes during fMRI studies but also responds strongly to nonscene landmark objects, such as buildings, ...

BACKGROUND: Diabetes prevalence is high worldwide, affecting entire populations. Yet some population groups are more susceptible than others. In contemporary western societies, socioeconomically disadvantaged groups are disproportionally affected. The pattern is less clear for diabetes mortality. Researchers argue increasingly in favour of looking beyond individual socioeconomic position (SEP). In light ...

Improving maternal nutrition is an important step toward reducing low birth weight (LBW) and its sequelae. In India, an estimated 7.5 million babies are born each year with LBW, which accounts for more than one-third of the global burden. In this context, little is known about the population-level association of ...

AIMS: Mutant protein aggregation cardiomyopathy (MPAC) is characterized by reductive stress (RS), protein aggregation (of chaperones and cytoskeletal components) and ventricular dysfunction in transgenic mice expressing human mutant CryAB (hmCryAB). Sustained activation of Nrf2 causes reductive stress, which contributes to proteotoxic cardiac disease. The goals of this pre-clinical study were ...

AIMS: The complex molecular mechanisms underlying spontaneous cardiac pacemaking are not fully understood. Recent findings point to a coordinated interplay between intracellular Ca(2+) cycling and plasma membrane localized cation transport determining the origin and periodicity of pacemaker potentials. The sodium-calcium exchanger (NCX1) is a key sarcolemmal protein for the maintenance ...

Body nitrogen retention is dependent on the amount of dietary protein consumed, as well as the fat and carbohydrate content in the diet, due to the modulation of amino acid oxidation. PPARα is a transcription factor involved in the upregulation of the expression of enzymes of fatty acid oxidation. However, ...

Systemic administration of the noncompetitive N-methyl-D-aspartate (NMDA)- receptor antagonist, MK-801, has been proposed to model cognitive deficits similar to those seen in patients with schizophrenia. Evidence has shown that MK-801 increases the probability of operant responding during extinction, possibly modeling perseveration, as would be seen in patients with schizophrenia. This ...

The central noradrenergic neurone, like the peripheral sympathetic neurone, is characterized by a diffusely arborizing terminal axonal network. The central neurones aggregate in distinct brainstem nuclei, of which the locus coeruleus (LC) is the most prominent. LC neurones project widely to most areas of the neuraxis, where they mediate dual ...

Although oral bisphosphonates (BP) are highly effective in preventing fractures, some patients will fracture while on treatment. We identified predictors of such fractures in a population-based cohort of incident users of oral BP. We screened the SIDIAP database to identify new users of oral BP in 2006-2007. SIDIAP includes pharmacy ...

The endogenous cannabinoids 2-arachidonoylglycerol (2-AG) and anandamide (AEA) play vital roles during nervous system development. The degradation of 2-AG and AEA is mediated by monoacylglycerol lipase (MAGL) and fatty acid amide hydrolase (FAAH), respectively. These enzymes are inhibited following developmental chlorpyrifos (CPF) exposure. To investigate whether this inhibition is persistent ...
