BACKGROUND: Pacing at higher rates is known to suppress Torsade de Pointes (TdP) arrhythmias. Nevertheless, exact application and mechanism need further clarification. In the anesthetized, canine, chronic atrioventricular block model, ventricular remodeling is responsible for a high and reproducible incidence of TdP upon a challenge with dofetilide. OBJECTIVE: We used this model to investigate by what mechanism accelerated pacing averts TdP and what repolarization parameter could be used to guide temporary applied accelerated pacing (TAP)...

Cell survival and proliferation are central to carcinogenesis, involving various mechanisms among which those that impede apoptosis are important. In this, the role of the molecular chaperone Hsp60 is unclear since it has been reported that it can be both, pro- or anti-apoptotic. A solution to this riddle is crucial to the development of anti-cancer therapies targeting Hsp60. We addressed this question using a tumor cell line, NCI-H292, and [Cu(3,5-bis(2'-pyridyl)-1,2,4-oxadiazole)2(H2O)2](ClO4)2, CubipyOXA, a copper-containing compound with cytotoxic properties...

Accurate DNA replication is crucial for cell survival and the maintenance of genome stability. Cells have developed mechanisms to cope with the frequent genotoxic injuries that arise from both endogenous and environmental sources. Lesions encountered during DNA replication are often tolerated by post-replication repair mechanisms that prevent replication fork collapse and avert the formation of DNA double strand breaks. There are two predominant post-replication repair pathways, trans-lesion synthesis (TLS) and template switching (TS)...

BACKGROUND: Multiple studies have demonstrated the relationship between contrast volume (CV) and the risk of acute kidney injury (AKI). Quantification of total CV is often estimated and therefore may be inaccurate. We describe validation of a novel contrast monitoring system (CMS) (Osprey Medical), which is designed to detect and display injection by injection and total CV use on a monitor system in real time. METHODS: Thirty patients undergoing a coronary or peripheral angiogram were included...

Previous behavioral studies have demonstrated an effect of eye gaze direction on the processing of emotional expressions in adults with social anxiety. However, specific brain responses to the interaction between gaze direction and facial expressions in social anxiety remain unclear. The present study aimed to explore the time course of such interaction using event-related potentials (ERPs) in participants with social anxiety. High socially anxious individuals and low socially anxious individuals were asked to identify the gender of angry or neutral faces with direct or averted gaze while their behavioral performance and electrophysiological data were monitored...

BACKGROUND: Over 200 million people worldwide live with groin hernia and 20 million are operated on each year. In resource-scarce settings, the superior surgical technique using a synthetic mesh is not affordable. A low-cost alternative is needed. The objective of this study was to calculate and compare costs and cost-effectiveness of inguinal hernia mesh repair using a low-cost versus a commercial mesh in a rural setting in Uganda. METHODS: This is a cost-effectiveness analysis of a double-blinded RCT comparing outcomes from groin hernia mesh repair using a low-cost mesh and a commercially available mesh...

Adaptation of agents through learning or evolution is an important component of the resilience of Complex Adaptive Systems (CAS). Without adaptation, the flexibility of such systems to cope with outside pressures would be much lower. To study the capabilities of CAS to adapt, social simulations with agent-based models (ABMs) provide a helpful tool. However, the value of ABMs for studying adaptation depends on the availability of methodologies for sensitivity analysis that can quantify resilience and adaptation in ABMs...

: Recently, hyaluronic acid (HA) hydrogels have been extensively researched for delivering cells and drugs to repair damaged tissues, particularly articular cartilage. However, the in vivo degradation of HA is fast, thus limiting the clinical translation of HA hydrogels. Furthermore, HA cannot bind proteins with high affinity because of the lack of negatively charged sulfate groups. In this study, we conjugated sulfate groups to HA. These sulfated HA exhibit significantly slower degradation by hyaluronidase compared to the wild type HA...

Long periods of bed rest negatively affect the human body organs, notably the cardiovascular system. To avert these negative effects and promote functional recovery in patients dealing with prolonged bed rest, the goal is to mobilize them as early as possible while controlling and stabilizing their cardiovascular system. A robotic tilt table allows early mobilization by modulating body inclination, automated passive leg exercise, and the intensity of functional electrical stimulation applied to leg muscles (inputs)...

BACKGROUND: The pork tapeworm, Taenia solium, and associated human infections, taeniasis, cysticercosis and neurocysticercosis, are serious public health problems, especially in developing countries. The World Health Organization (WHO) has set goals for having a validated strategy for control and elimination of T. solium taeniasis/cysticercosis by 2015 and interventions scaled-up in selected countries by 2020. Timely achievement of these internationally-endorsed targets requires that the relative benefits and effectiveness of potential interventions be explored rigorously within a quantitative framework...

Emotional influences on fertility behaviors are an understudied topic that may offer a clear explanation of why many couples choose to have children even when childbearing is not economically rational. With setting-specific measures of the husband-wife emotional bond appropriate for large-scale population research matched with data from a long-term panel study, we have the empirical tools to provide a test of the influence of emotional factors on contraceptive use to limit fertility. This article presents those tests...

A new methodological framework for assessing agreement between cost-effectiveness endpoints generated using alternative sources of data on treatment costs and effects for trial-based economic evaluations is proposed. The framework can be used to validate cost-effectiveness endpoints generated from routine data sources when comparable data is available directly from trial case report forms or from another source. We illustrate application of the framework using data from a recent trial-based economic evaluation of the probiotic Bifidobacterium breve strain BBG administered to babies less than 31 weeks of gestation...

Occludin is a key tight junction (TJ) protein in cerebral endothelial cells (CECs) playing an important role in modulating blood-brain barrier (BBB) functions. This protein (65kDa) has been shown to engage in many signaling pathways and phosphorylation by both tyrosine and threonine kinases. Despite yet unknown mechanisms, pro-inflammatory cytokines and endotoxin (lipopolysaccharides, LPS) may alter TJ proteins in CECs and BBB functions. Here we demonstrate the responses of occludin in an immortalized human cerebral endothelial cell line (hCMEC/D3) to stimulation by TNFα (10 ng/mL), IL-1β (10 ng/mL) and LPS (100 ng/mL)...

BACKGROUND: Understanding the spatial distribution of stunting and underlying factors operating at meso-scale is of paramount importance for intervention designing and implementations. Yet, little is known about the spatial distribution of stunting and some discrepancies are documented on the relative importance of reported risk factors. Therefore, the present study aims at exploring the spatial distribution of stunting at meso- (district) scale, and evaluates the effect of spatial dependency on the identification of risk factors and their relative contribution to the occurrence of stunting and severe stunting in a rural area of Ethiopia...
