Exposure to polycyclic aromatic hydrocarbons (PAH) negatively impacts exercise performance in fish species but the physiological modifications that result in this phenotype are poorly understood. Prior studies have shown that embryonic and juvenile mahi-mahi (Coryphaeus hippurus) exposed to PAH exhibit morphological abnormalities, altered cardiac development and reduced swimming performance. It has been suggested that cardiovascular function inhibited by PAH exposure accounts for the compromised exercise performance in fish species...

Choline alfoscerate (α-GPC) is a common choline compound and acetylcholine precursor in the brain, which has been shown to be effective in the treatment of Alzheimer's disease and dementia. α-GPC has been shown to enhance memory and cognitive function in stroke and Alzheimer's patients but currently remains untested in patients suffering from epilepsy. This study aimed to evaluate whether α-GPC treatment after seizure can ameliorate seizure-induced cognitive impairment and neuronal injury. The potential therapeutic effects of α-GPC on seizure-induced cognitive impairment were tested in an animal model of pilocarpine-induced seizure...

BACKGROUND: Although aortic valve-sparing (AVS) operations are established alternatives to composite valve graft (CVG) procedures for patients with aortic root aneurysms, comparative long-term outcomes are lacking. OBJECTIVES: This study sought to compare the results of patients undergoing AVS procedures with those undergoing CVG operations. METHODS: From 1990 to 2010, a total of 616 patients age <70 years and without aortic stenosis underwent elective aortic root surgery (AVS, n = 253; CVG with a bioprosthesis [bio-CVG], n = 180; CVG with a mechanical prosthesis [m-CVG], n = 183)...

Cannabis is a frequently used illicit recreational drug that is known to be associated with a variety of psychopharmacological effects. Negative somatic effects such as myocardial infarction and stroke have been reported, though, less frequently. Most of the literature available has focused on the complications due to smoked forms of cannabis (ganja and charas). Here we report a case of acute myocardial ischaemia with acute ischaemic stroke developing after oral ingestion of 'Bhang', a preparation of cannabis...

Low frequency-pulsed electromagnetic fields (LF-PEMFs) affect many biological processes; however, the fundamental mechanisms responsible for these effects remain unclear. Our study aimed to investigate the effect of LF-PEMFs on neuroprotection after ischemic stroke. C57B6 mice were exposed to LF-PEMF (F = 60 Hz, Bm = 10 mT) after photothrombotic occlusion. We measured the BDNF/TrkB/Akt signaling pathway, pro-apoptotic and pro-survival protein and gene expressions, and the expression of inflammatory mediators and performed behavioral tests in both LF-PEMF-treated and untreated ischemic stroke mice...

The aim of this study was to evaluate the influence of dry-land inertial training (IT) on muscle force, muscle power, and swimming performance. Fourteen young, national-level, competitive swimmers were randomly divided into IT and control (C) groups. The experiment lasted four weeks, during which time both groups underwent their regular swimming training. In addition, the IT group underwent IT using the Inertial Training Measurement System (ITMS) three times per week. The muscle groups involved during the upsweep phase of the arm stroke in front crawl and butterfly stroke were trained...

BACKGROUND: Left atrial (LA) compliance and contractility influence left ventricular stroke volume. We hypothesized that diminished LA compliance and contractile function occur early during the development of heart failure with preserved ejection fraction (HFpEF) and impair overall cardiac performance. METHODS AND RESULTS: Cardiac magnetic resonance imaging, echocardiography, left ventricular and LA pressure-volume studies, and tissue analyses were performed in a model of early HFpEF (elderly dogs, renal wrap-induced hypertension, exogenous aldosterone; n=9) and young control dogs (sham surgery; n=13)...

BACKGROUND: We have previously confirmed the importance of rat chromosome 3 (RNO3) genetic loci on blood pressure elevation, pulse pressure (PP) variability and renal pathology during salt challenge in the stroke-prone spontaneously hypertensive (SHRSP) rat. The aims of this study were to generate a panel of RNO3 congenic sub-strains to genetically dissect the implicated loci and identify positional candidate genes by microarray expression profiling and analysis of next-generation sequencing data...

OBJECTIVE: Recently several studies reported that anti-hypertensive drugs were associated with development of new-onset diabetes mellitus (NODM). However, data on the relationship between detailed prescription types and long-term incidence of NODM are still limited in Asian patients (pts). DESIGN AND METHOD: A total of 3,208 consecutive hypertension pts prescribed with calcium channel blockers (CCB) were enrolled with the exclusion of diabetic pts. Pts were divided into two groups according to the additional prescription of renin angiotensin system (RAS) blockers; 1) the CCB group (n = 1,987) and 2) CCB + RAS group (n = 1,221)...

OBJECTIVE: Hypertension has been discussed as a key role in developing cardiovascular diseases. The stroke incidence is relatively high in South Korea compared to other countries. In our research, we quantified the impact of hypertension by estimating population attributable-risk in the development of stroke. DESIGN AND METHOD: We selected 154,786 people aged over 40 among National Health Insurance Service-National sample cohort who have not diagnosed either stroke or TIA within baseline periods (2002-2005)...

Younger adults (ages ≤50 years) are increasingly prone to stroke, chronic kidney disease (CKD), and worsening cardiovascular disease (CVD) mortality in the US. An alarming increase in prevalence of high blood pressure (BP) related to the obesity epidemic appears to underlie these adverse trends. However, what specific BP characteristics measured in young adulthood optimally predict incident CVD and CKD later in life remains to be determined. Therefore, an optimization of diagnostic and therapeutic strategies in BP management for young adults is challenging but essential...

Disease risk prediction models have been developed to assess the impact of multiple risk factors and to estimate an individual's absolute disease risk. Accurate disease prediction is essential for personalized prevention, because the benefits, risks, and costs of alternative strategies must be weighed to choose the best preventive strategy for individual patients. Cardiovascular disease (CVD) prediction is the earliest example of individual risk predictions. Since the Framingham study reported a CVD risk prediction method in 1976, an increasing number of risk assessment tools have been developed to CVD risk in various settings...

This study investigated the effects of weight-shifting exercise (WSE) combined with transcutaneous electrical nerve stimulation (TENS), applied to the erector spinae and external oblique (EO) muscles, on muscle activity and trunk control in patients with hemiparetic stroke. Sixty patients with stroke were recruited to this study and randomly distributed into three treatment groups: (1) WSE + TENS, (2) WSE + placebo TENS, and (3) control. All participants underwent 30 sessions of training (30 minutes five times per week for 6 weeks) and received 1 hour of conventional physical therapy five times per week for 6 weeks...

This case report describes a 41-year-old previously healthy male who presented with stuttering transient ischemic symptoms and radiographic evidence of a left common carotid artery thrombus as well as acute and subacute ischemic infarcts in the left middle cerebral artery territory. An exhaustive stroke work-up did not provide a plausible etiology for his symptoms. His complete blood count and iron studies, however, revealed evidence of severe iron-deficiency anemia without reactive thrombocytosis. His stool guaiac test was positive...

Carotid artery dissection (CAD) is a frequent cause of stroke, accounting for up to 25% of all ischemic strokes in young and middle-aged patients.(1,2) It may be traumatic or spontaneous, with multi-factorial etiology. A tear in the arterial wall causes intrusion of blood within its layers, producing intra-luminal stenosis, or aneurysmal dilatation.(3) Thrombo-embolism arising from this anatomic disruption has been postulated as the essential stroke mechanism in CAD.(4) Bilateral internal carotid artery dissection (ICAD) has been rarely reported...

BACKGROUND: Given the young age of onset and the high probability of long-term disability after SAH, the financial impact is expected to be substantial. Primary objective was to highlight subsequent treatment costs after the acute in-hospital stay including rehabilitation and home care in comparison to ischemic stroke. METHODS: The study included 101 patients with aneurysmal SAH treated July 2007 through April 2009. In-hospital expenses were calculated using the German Diagnose Related Groups DRG...

AIMS: Different cardiac arrhythmias have been suggested to be associated with Danon disease, e.g. Wolff-Parkinson-White syndrome. However, a systematic electrophysiological investigation of patients with Danon disease is lacking thus far. METHODS AND RESULTS: Seven patients with Danon disease (4 males, 35.8 ± 10.8 years; 3 females, 51.3 ± 19.9 years) from 3 different families were studied. In all patients, the presence of Danon disease was confirmed by western blot of biopsy material or genetic testing...
