BACKGROUND: Endothelial colony-forming cells (ECFCs), also termed late outgrowth endothelial cells, are a well-defined circulating endothelial progenitor cell type with an established role in vascular repair. ECFCs have clear potential for cell therapy to treat ischaemic disease, although the precise mechanism(s) underlying their response to hypoxia remains ill-defined. METHODS: In this study, we isolated ECFCs from umbilical cord blood and cultured them on collagen...

BACKGROUND: Clostridium septicum is a rare cause of meningitis and brain abscess in children and adults. Gas production by the pathogen can lead to pneumocephalus and the overall mortality rate of Clostridium septicum CNS infection is as high as 74%. The most common entry site of the pathogen is the gastrointestinal tract. CASE PRESENTATION: We describe a 74-year-old man who presented with a left-sided cerebral infarction in the middle cerebral artery territory...

A unique and highly versatile technique, stress echocardiography (SE) is increasingly recognized for its utility in the evaluation of non-ischaemic heart disease. SE allows for simultaneous assessment of myocardial function and haemodynamics under physiological or pharmacological conditions. Due to its diagnostic and prognostic value, SE has become widely implemented to assess various conditions other than ischaemic heart disease. It has thus become essential to establish guidance for its applications and performance in the area of non-ischaemic heart disease...

Modelling cardiac electrophysiology (EP) can help understand pathologies and predict the response to therapies. Moreover, estimating patient-specific parameters of the EP model is crucial to obtain personalised information. The novelty of this paper is to use non-invasive data (body surface potential mapping, BSPM) in order to personalise the main parameters of a cardiac EP model for predicting different pacing conditions. First, an efficient forward model is proposed, coupling the Mitchell- Schaeffer transmembrane potential model with a current dipole formulation...

INTRODUCTION: Close monitoring of blood glucose levels during the immediate post-acute stroke phase is of great clinical value, as there is evidence that the risk of neurological deterioration is associated with both hyper- and hypoglycaemia. The aim of this review paper is to summarise the evidence on post-stroke blood glucose management and its impact on clinical outcomes, during the early post-acute stage. FINDINGS: Post-stroke hyperglycaemia has been associated with increased cerebral oedema, haemorrhagic transformation, lower likelihood of recanalisation and deteriorating neurological state...

OBJECTIVE: Ischaemic stroke is a leading cause of death and disability. Autoregulation and collateral blood flow through the circle of Willis both play a role in preventing tissue infarction. To investigate the interaction of these mechanisms a one-dimensional steady state model of the cerebral arterial network was created. METHODS: Structural variants of the circle of Willis that present particular risk of stroke were recreated using a network model coupled with: (1) a steady state physiological model of cerebral autoregulation; (2) one wherein the cerebral vascular bed was modelled as a passive resistance...

BACKGROUND: Alcohol consumption is steadily increasing in high-income countries but the harm and possible net benefits of light-to-moderate drinking remain controversial. We prospectively investigated the association between time-varying alcohol consumption and overall and cause-specific mortality among middle-aged women. METHODS: Among 48 249 women at baseline (33 404 at follow-up) in the prospective Swedish Women's Lifestyle and Health cohort, age 30-49 years at baseline, we used repeated information on alcohol consumption and combined this method with multiple imputation in order to maximise the number of participants and deaths included in the analyses...

REVIEW

The genetics of isolated colonic Crohn's disease place it approximately midway between Crohn's disease with small intestinal involvement and UC, making a case for considering it as a separate condition. We have therefore systematically reviewed its epidemiology, pathophysiology and treatment. Key findings include a higher incidence in females (65%) and older average age at presentation than Crohn's disease at other sites, a mucosa-associated microbiota between that found in ileal Crohn's disease and UC, no response to mesalazine, but possibly better response to antitumour necrosis factor than Crohn's disease at other sites...

Hypoxia-inducible factor 1α (HIF-1α) controls many genes involved in physiological and pathological processes. However, its roles in glutamatergic transmission and excitotoxicity are unclear. Here, we proposed that HIF-1α might contribute to glutamate-mediated excitotoxicity during cerebral ischaemia-reperfusion (CIR) and investigated its molecular mechanism. We showed that an HIF-1α conditional knockout mouse displayed an inhibition in CIR-induced elevation of extracellular glutamate and N-methyl-D-aspartate receptor (NMDAR) activation...

Photoperiod disruption, which occurs during shift work, is associated with changes in metabolism or physiology (e.g. hypertension and hyperglycaemia) that have the potential to adversely affect stroke outcome. We sought to investigate if photoperiod disruption affects vulnerability to stroke by determining the impact of photoperiod disruption on infarct size following permanent middle cerebral artery occlusion. Adult male Wistar rats (210-290 g) were housed singly under two different light/dark cycle conditions (n = 12 each)...

Acute renal failure (ARF) is a syndrome of abrupt decline in renal function induced by a number of different insults. In clinic, the common etiology for ARF is ischemia-reperfusion injury (IRI). The pathophysiological process of renal IRI is complex, there is no good treatment. Stem cell therapy is a new and promising treatment for renal IRI. Mesenchymal stem cells (MSCs) have the ability to differentiate into tissues of mesodermal lineages. MSCs are under intensive study as potential therapeutic strategy for renal IRI...

The strategy of Remote Ischaemic Conditionings (RIC) is easy to apply, cost effective, low in side effects and belongs to the most potent cardioprotective strategies evaluated within recent years. Its practical application is carried out by simple use of a blood pressure cuff, more precise by 4 repetitive cycles of inflating the cuff above 200 mmHg for 5 minutes followed by an equal long break between the cycles. First experimental and clinical data repetitively demonstrated a significant reduction in myocardial injury following ischemia/reperfusion...

The renin angiotensin system (RAS) consists of the systemic hormone system, critically involved in regulation and homeostasis of normal physiological functions [i.e. blood pressure (BP), blood volume regulation], and an independent brain RAS, which is involved in the regulation of many functions such as memory, central control of BP and metabolic functions. In general terms, the RAS consists of two opposing axes; the 'classical axis' mediated primarily by Angiotensin II (Ang II), and the 'alternative axis' mediated mainly by Angiotensin-(1-7) (Ang-(1-7))...

BACKGROUND: Surfers myelopathy can be a rapidly devastating disease and little is known surrounding the pathophysiology of the condition. Although the classical pattern of illness has been well reported, it has never been observed in a non-surfing setting. METHODS: A 51-year-old demolition worker presented with acute non-traumatic myelopathy. Clinical examination revealed sensory loss to the level of L2. T2-MRI and MRI-DWI revealed a hyperintense signal suggestive of an ischaemic event...
