INTRODUCTION: Catheter ablation (CA) is an established and widespread treatment option for drug refractory atrial fibrillation (AF). CA has undergone considerable improvements during the last years and several ablation strategies have been proposed for different AF patterns. EVIDENCE ACQUISITION: The main cornerstone is the electrical isolation of pulmonary veins (PVs) especially among patients with paroxysmal AF. This can be achieved mainly with the use of radiofrequency or cryo-energy...

Cardiovascular disease (CVD) is the leading cause of death in the western world, in both genders. Although awareness of the importance of prevention, diagnosis and optimal treatment of CVD has risen in general, most women are not fully aware of their CVD risk. Moreover, women are not alert to the burden of risk in their reproductive years (e.g. complicated pregnancy and/or peri-menopausal period) and their impact on future CVD. Unique Female issues such as: fertile age, menopause, oral contraceptives, hormonal and metabolic disorders during pregnancy, labor, as well as psychological matters, and healthy life-style are major contributors to primary and secondary prevention of CVD...

Abdominal pregnancy is a very rare obstetric complication which is seriously hazardous to the mother as well as the fetus. It poses a diagnostic challenge to this day. Both maternal and fetal mortality rates in such cases are high, as well as the malformation rate among the affected fetus. The best diagnostic tools are ultrasound and MRI. The availability of these instruments, and especially the latter, is scarce in developing countries, hence the higher rate of this type of pregnancy in these regions. The higher incidence of abdominal pregnancy in developing countries is also associated with the greater prevalence of low socioeconomic status, pelvic infections and infertility - all are more prevalent in these countries...

Due to considerable progress in exhaust control emission technology and extensive regulatory work regarding this issue, non-exhaust sources of air pollution have become a growing concern. This research involved studying three types of road environment samples such as road dust, sludge from storm drains and roadside soil collected from heavily congested and polluted cities in Poland (Krakow, Warszawa, Opole and Wroclaw). Particles below 20 µm were examined since it was previously estimated that this fine fraction of road dust is polluted mostly by metals derived from non-exhaust sources of pollution such as brake linings wear...

PURPOSE: The mitogen-activated protein kinase phosphatases (MKPs) are a family of dual-specificity phosphatases that inactivate MAPKs by dephosphorylation. Impairment of MKP-1 expression in insulin resistance has been suggested to affect the cardioprotective properties of insulin. We hypothesized that manipulation of its activity during myocardial ischaemia/reperfusion of control as well as insulin-resistant rats may affect the outcome. METHODS: Hearts from 16 week dietary induced obese Wistar rats and their age matched controls were isolated, perfused in the working mode and subjected to 15 min global ischaemia / 30 min reperfusion or 35 min coronary artery ligation/ 60 min reperfusion...

From a biological perspective, a natural product can be defined as a compound evolved by an organism for chemical interactions with another organism including prey, predator, competitor, pathogen, symbiont or host. Natural products hold tremendous potential as drug leads and have been extensively studied by chemists and biochemists in the pharmaceutical industry. However, the biological purpose for which a natural product evolved is rarely addressed. By focusing on a well-studied group of natural products-venom components from predatory marine cone snails-this review provides a rationale for why a better understanding of the evolution, biology and biochemistry of natural products will facilitate both neuroscience and the potential for drug leads...

More patients are surviving long-term following a cancer diagnosis and as such are at risk for second malignancies. As the most common primary brain tumor, glioblastoma (GBM) will not infrequently occur in this population. No study has examined the incidence of prior cancer (PC) in patients harboring GBM. Here we evaluate the epidemiological features, as well as the molecular and clinical characteristics of GBM as a second cancer. Utilizing a web-based cancer data management system at our institution, we identified 2164 patients harboring GBM from 2007 to 2014...

Maladaptive patterns of cardiac adjustment to stress in adolescents may reveal their vulnerability to anxiety disorders (ADs). Traditional research in this field has focused on anxiety levels, whereas the time course of anxiety has rarely been considered. Nevertheless, since overall anxiety decreases as adolescence progresses, increasing time courses are clinically relevant and can be associated with maladaptive contextual adjustment. In this study, the cardiac pattern of adjustment to stress in adolescents with increasing anxiety was analysed...

Starch-enriched brewery waste (SBW), an unexplored feedstock, was investigated as a nutritious low-cost source for the mixotrophic cultivation of Ettlia sp. YC001 for biodiesel production. Stirring, autoclaving, and sonication were assessed for the SBW, in conjunction with pH. Stirring at 55 °C was found to be the best, in terms of the effectiveness of starch hydrolysis and yeast disintegration as well as cost. The treated solutions were found to support the mixotrophic growth of microalgae: 20 g/L of glucose medium resulted in the highest biomass production of 9...

The heart must function continuously as it is responsible for both supplying oxygen and nutrients throughout the entire body, as well as for the transport of waste products to excretory organs. When facing either a physiological or pathological increase in cardiac demand, the heart undergoes structural and functional remodeling as a means of adapting to increased workload. These adaptive responses can include changes in gene expression, protein composition, and structure of sub-cellular organelles involved in energy production and metabolism...

Cardiac tissue responds to long-term hemodynamic load through initiation of a hypertrophic remodeling program. Importantly, if not counteracted this response will eventually lead to organ failure. Cardiac hypertrophic adaptations are complex, and involve multiple cellular events and the mechanisms underlying the development of cardiac hypertrophy are not well understood. Mitochondrial dysfunction has been indicated as a potential and important player in the development of cardiac hypertrophy. Additionally, substantial evidence shows that a significant portion of mitochondrial processes, necessary for normal cardiomyocyte physiology, are impacted by these hypertrophic changes...

The use of remote optical feedback systems represents a promising approach for minimally invasive, nerve-sparing laser surgery. Autofluorescence properties can be exploited for a fast, robust identification of nervous tissue. With regard to the crucial step towards clinical application, the impact of laser ablation on optical properties in the vicinity of structures of the head and neck has not been investigated up to now. We acquired 24,298 autofluorescence spectra from 135 tissue samples (nine ex vivo tissue types from 15 bisected pig heads) both before and after ER:YAG laser ablation...

Genetic factors might be largely responsible for the development of autism spectrum disorder (ASD) that alone or in combination with specific environmental risk factors trigger the pathology. Multiple mutations identified in ASD patients that impair synaptic function in the central nervous system are well studied in animal models. How these mutations might interact with other risk factors is not fully understood though. Additionally, how systems outside of the brain are altered in the context of ASD is an emerging area of research...
