Background: Regular preventive chemotherapy (PCT) targeting high-risk populations is an effective way to control STH in the short term, but sustainable long-term STH control is expected to require improved access to water, sanitation, and hygiene (WASH). However, experimental studies have not been able to conclusively demonstrate the benefit of WASH in preventing STH (re-)infections. We investigated the impact of WASH on STH infections during and after PCT using mathematical modelling. Read More

Less schooling is associated with increased biological risks for chronic disease, but whether increasing years of schooling through policy interventions reduces these risks remains unclear. We examine the effect of a major education reform introduced in 1959 that raised the minimum school leaving age from 14 to 16 years in France, offering a unique natural experiment. We assess the causal impact of increased schooling duration on 16 biomarkers of cardiovascular, metabolic, organ and immune function in a large cohort of men and women born around 1953. Read More

The nonlinear electrokinetic motion of electrically induced Janus droplets (EIJDs) in a microchannel is studied in this paper. The EIJDs were fabricated by operating the positively charged aluminum oxide nanoparticles to partially cover the oil droplets with electric field. The nanoparticle coverage of the EIJDs changes with the electric field strength, which leads to the variation of the electrophoretic mobility of the EIJDs. Read More

Because the application of Bisphenol A (BPA) was restricted, many substitutes, such as Bisphenol F (BPF) and Bisphenol S (BPS), were developed as BPA substitutes. Therefore, environmental impacts of BPA and its substitutes on aquatic organisms should be concerned, especially their combined toxicity. In this study, the impacts of BPA, BPF, BPS and their mixture on the feeding behavior, reproduction and physiological function of daphnids were synthetically evaluated, involving the duration and mode of exposure.

Interferons (IFNs) are key players in the tumor immune response and act by inducing the expression of IFN-stimulated genes (ISGs). Here, we identify the mixed-lineage kinase domain-like pseudokinase (MLKL) as an ISG in various cancer cell lines. Both type I and type II IFNs increase the expression of MLKL indicating that MLKL up-regulation is a general feature of IFN signaling. Read More

The innate immune system is the first line of defense against pathogenic threats. For the early pathogen recognition and activation of cell protective mechanisms, germline-encoded pattern recognition receptors (PRRs) detect characteristic and evolutionary conserved pathogen-associated molecular patterns (PAMPs). PRRs are therefore key elements in the innate immune response; in addition, they sense danger-associated molecular patterns (DAMPs) that are released by host cell molecules under pathophysiological conditions.

Radiotherapy plays a vital role in cancer treatment, for which accurate prognosis is important for guiding sequential treatment and improving the curative effect for patients. An issue of great significance in radiotherapy is to assess tumor radiosensitivity for devising the optimal treatment strategy. Previous studies focused on gene expression in cells closely associated with radiosensitivity, but factors such as the response of a cancer patient to irradiation and the patient survival time are largely ignored.

The sympathetic nervous system is the main stimulator of cardiac function. While acute activation of the β-adrenoceptors exerts positive inotropic and lusitropic effects by increasing cAMP and Ca, chronically enhanced sympathetic tone with changed β-adrenergic signaling leads to alterations of gene expression and remodeling. The CREB-regulated transcription coactivator 1 (CRTC1) is activated by cAMP and Ca. Read More

It is well-known that both emotional and motivational events greatly impact our behaviour. Based on previous work on the interplay between these two constructs, the present study aimed to test whether and how concurrent emotion and reward signals interact in terms of their basic valence, when both are equally relevant to the task. To this end, we employed a novel fMRI paradigm in which reward availability was explicitly signalled by positive, neutral, or negative facial expressions (using block-wise instructions). Read More

Understanding how cortical activity generates sensory perceptions requires a detailed dissection of the function of cortical layers. Despite our relatively extensive knowledge of their anatomy and wiring, we have a limited grasp of what each layer contributes to cortical computation. We need to develop a theory of cortical function that is rooted solidly in each layer's component cell types and fine circuit architecture and produces predictions that can be validated by specific perturbations.

More than 70% of the population in Mexico is overweight or obese, affecting mainly people in productive age. Obesity is associated with the development of diseases that increase cardiovascular risk (diabetes mellitus, hypertension or atherogenic dyslipidemia), diseases that limit the quality of life of the patient (osteoarthrosis or sleep apnea) and even with the increase in the incidence of certain types of cancer (breast or colon). It is evident that the decrease of at least 5% of body weight induces improvement in all these factors; however, in some patients it is difficult to achieve this goal only with lifestyle modifications.

Background And Purpose: Acute insulin administration results in a hyperpolarization and concomitant decrease of firing rate in a subpopulation of arcuate Proopiomelanocortin (POMC) and Neuropeptide Y/Agouti-related peptide (NPY/AgRP) cells. This rapid effect on cellular activity has been implicated as a cellular correlate of insulin effects on energy balance and glucose homeostasis. Recent evidence suggests that zinc in mammalian insulin formulations is required for the insulin-induced inhibition of arcuate POMC neurons, while guinea-pig insulin, which fails to bind zinc, activates POMC neurons in mice.

NWC is an uncharacterised protein containing three strongly conserved domains not found in any other known protein. Previously, we reported that the NWC protein is detected in cells in the germinal layer in murine testes (strain: C57BL/6), and its knockout results in no obvious phenotype. We determined the NWC expression pattern during spermatogenesis, and found this protein in spermatocytes and round spermatids, but not in epididymal sperm. Read More

Since multi-view data are available in many real-world clustering problems, multi-view clustering has received considerable attention in recent years. Most existing multi-view clustering methods learn consensus clustering results but do not make full use of the distinct knowledge in each view so that they cannot well guarantee the complementarity across different views. In this paper, we propose a Distinction based Consensus Spectral Clustering (DCSC), which not only learns a consensus result of clustering, but also explicitly captures the distinct variance of each view.

Nanoscale metallic glasses (MGs) are frequently used in experimental and computational studies to probe the deformation mechanisms in amorphous metals. Potential consequences of the significant surface to volume ratio in these extremely small materials, nevertheless, are not well understood. Here, using molecular dynamics simulations and novel selective 3D visualization, we show that significant irreversible atomic shear strain condenses on the 3D surface of these materials under low uniaxial stress, while the interior atoms are bearing much lower, mostly reversible shear strain.
