BACKGROUND: Little is know about whether the effects of community engagement interventions for child survival in low-income and middle-income settings are sustained. Seasonal variation and secular trend may blur the data. Neonatal mortality was reduced in a cluster-randomised trial in Vietnam where laywomen facilitated groups composed of local stakeholders employing a problem-solving approach for 3 years. In this analysis, we aim at disentangling the secular trend, the seasonal variation and the effect of the intervention on neonatal mortality during and after the trial...

Erosion of vertebral bodies by an abdominal aortic aneurysm is extremely rare. Chronic contained rupture can cause difficulties in diagnosis because there are many clinical presentations: back pain, sciatic pain, or an expansive abdominal mass. Computed tomography is the gold-standard diagnostic tool. We report the case of a 49-year-old man who suffered from back pain because of a chronic ruptured aortic aneurysm.

The complexity of snake venoms has long been investigated to explore a myriad of biologically active proteins and peptides that are used for immobilizing or killing prey, and are responsible for the pathological effects observed upon envenomation. Glycosylation is the main post-translational modification (PTM) of viperid venoms but currently there is little understanding of how protein glycosylation impacts the variation of venom proteomes. We have previously reported that Bothrops venom glycoproteomes contain a core of components that markedly define their composition and parallel their phylogenetic classification...

Thin film of amorphous tungsten-doped cobalt oxide (W:CoO) was successfully grown on a conducting electrode via an electrochemical oxidation process employing a [Co(WS4)2]2- deposition bath. The W:CoO catalyst displays attractive performance for the oxygen evolution reaction in an alkaline solution. In the pH 13 NaOH solution, the best W:CoO operates with moderate onset overpotential of 230 mV and requires 320 mV overpotential to generate a catalytic current density of 10 mA.cm-2. Low Tafel slope of 45 mV.decade-1 was determined, indicating a rapid O2-evolving kinetics...

The Red River basin (RRB) exhibits substantial variation of water resource seasonally and annually. Sustainable water resource management in the RRB has been challenging due to the lack of in situ hydrological measurement data over the basin-wide scale. To address this issue, this study aimed to perform the setting up, calibration, and validation of the variable infiltration capacity (VIC) hydrological model forced with ground- and satellite-based datasets at a high spatial resolution of 0.1° for simulating the daily river flow of the Red River system in the RRB during the period of 2005-2014...

BACKGROUND: Ventilator-associated respiratory infection (VARI) comprises ventilator-associated pneumonia (VAP) and ventilator-associated tracheobronchitis (VAT). Although their diagnostic criteria vary, together these are the most common hospital-acquired infections in intensive care units (ICUs) worldwide, responsible for a large proportion of antibiotic use within ICUs. Evidence-based strategies for the prevention of VARI in resource-limited settings are lacking. Preventing the leakage of oropharyngeal secretions into the lung using continuous endotracheal cuff pressure control is a promising strategy...

We propose a new surgical technique for superior cavopulmonary anastomosis in patients with functionally univentricular heart and bilateral superior caval veins. One of the reasons of failed bidirectional Glenn shunts in patients with bilateral superior caval veins is the small caliber of one or both veins, with limited flow through each cavopulmonary anastomosis that can easily result in torsion, blockage, or clot formation. The conversion of two small superior caval veins into a single confluence which is large enough to connect with the pulmonary artery (PA) can resolve this problem...

Crosstalk among immune cells has attracted considerable attention with the advent of immunotherapy as a novel therapeutic approach for challenging diseases, especially cancer, which is the leading cause of mortality worldwide. Dendritic cells-the key antigen-presenting cells-play a pivotal role in immunological response by presenting exogenous epitopes to T cells, which induces the self-defense mechanisms of the body. Furthermore, nanotechnology has provided promising ways for diagnosing and treating cancer in the last decade...

Myocardial infarction (MI) leads to cardiomyocyte loss, impaired cardiac function, and heart failure. Molecular genetic analyses of myocardium in mouse models of ischemic heart disease have provided great insight into the mechanisms of heart regeneration, which is promising for novel therapies after MI. Although biomechanical factors are considered an important aspect in cardiomyocyte proliferation, there are limited methods for mechanical assessment of the heart in the mouse MI model. This prevents further understanding the role of tissue biomechanics in cardiac regeneration...
