This study aimed to explore the potential use of implantable heart rate loggers to quantify the TAB of Chrysoblephus laticeps, a marine Sparid, following the ECG method protocols. Of the nine experimental fish, only five (56%) returned accurate ƒHmax data. The TAB of successful trials was easily pinpointed 100% of the time and ranged from 18.09 to 20.10 °C. This study therefore provides evidence that implantable heart rate loggers can estimate TAB of fish which can be applied to many marine species.

Conclusion: There was a high prevalence of MetS and abnormal ECG among the studied population. Abnormal ECG findings were more common in men with no differential association in people with or without MetS. However, a significant association existed between certain components of MetS and ECG abnormalities in men only. Male gender and HDLc were independent predictors of ECG Abnormalities.Keyword: Electrocardiography, metabolic syndrome, africans.

AbstractThe presence of hypertensive mediated organ damage is related to increased vascular risk and mortality and its prevention should be a therapeutic target and a surrogate marker of in/adequate blood pressure control. In old adult hypertensive patients the therapeutic target should be to prevent major cardiovascular events, but in young hypertensive subjects the focus should be pointed on preventing the development of hypertensive mediated organ damage, since most of the hard events are preceded by functional and structural tissues injury. Hypertension Guidelines of the European Society of Cardiology and European Soci...

Authors: Akagi S, Miki T, Sando Y, Fujii N, Sarashina T, Nakamura K, Ito H Abstract Chronic-active Epstein-Barr virus infection (CAEBV) is a rare disease that can lead to pulmonary arterial hypertension (PAH). However, the treatment for CAEBV-associated PAH has not been established. We discuss a case of improved pulmonary hypertension after chemotherapy in a patient with CAEBV-associated PAH. A 44-year old man was admitted to our hospital because of an abnormal electrocardiogram and liver dysfunction detected by annual medical examination. Echocardiography showed a dilated right ventricle and an estimated right ven...

Authors: Chen J, Xu S, Zhou W, Wu L, Wang L, Li W Abstract The aim of this study was to investigate the effect of exendin-4 (Ex-4) on ventricular arrhythmias and calcium sparks-mediated calcium leak in a myocardial infarction-heart failure model.We studied the influence of exendin-4 on ventricular arrhythmogenesis in a rat myocardial infarction-heart failure model. In vivo arrhythmia studies (electrocardiogram [ECG] telemetry studies), ex vivo arrhythmia studies calcium sparks tests, and analysis of total and phosphorylated ryanodine receptor (RyR) 2 and CaMK-II were carried out in sham group, myocardial infarction...

We report the case of a 33-year-old woman with no history of coronary risk factors or chest pain who experienced intermittent chest pain at rest for several minutes from 2 PM. At 8 AM the next day, chest pain recurred and persisted for about 1 hour. She was transported to our hospital by ambulance, where electrocardiogram showed ST-elevation in the precordial leads, and blood tests showed elevation of cardiac markers. She was diagnosed with ST-elevation myocardial infarction. Because she was a young woman without any risk factors, coronary spastic angina was suspected. Coronary angiography without intracoronary nitrate adm...

Authors: Liu SH, Lai CT, Chen HR, Lin WL, Yamada S, Lugtu IC, Chou YH, Yang CCH, Kuo TB, Chen SA, Lo LW Abstract Sleep and estrogen levels have an impact on neural regulation and are associated with cardiovascular (CV) events. We investigated the effects of estrogen on heart rate variability (HRV) and circadian cycle in spontaneously hypertensive rats (SHRs). Polysomnographic recording was performed in seven male and seven female SHRs during sleep. The electroencephalogram (EEG) and electromyogram (EMG) were evaluated to define active waking (AW), quiet sleep (QS), and paradoxical sleep (PS) stages. Cardiac activit...

UlihinAbstractNanocomposite electrode materials composed of graphite, Ag and AgCl were prepared by impregnation of graphite with a suspension of silver nanoparticles followed by anodizing in hydrochloric acid to obtain a layer of silver chloride on the surface of the nanoparticles. Silver nanoparticles were synthesized by the reduction of silver salts in benzyl alcohol. It was shown that the mass fraction of 1% Ag in the nanocomposite is optimal for creating a uniform coating of c...
