This study describes an actuated bioreactor which mimics the pulsatile contractile motion of the intestinal barrier using electro-responsive elastomers as smart materials that undergo deformation upon electrical stimulation. The device consists of an annular dielectric elastomer actuator working as a radial artificial muscle able to rhythmically contract and relax a central cell culture well. The bioreactor maintained up to 4 h of actuation at a frequency of 0.15 Hz and a strain of 8%-10%, to those of the cyclic contraction and relaxation of the small intestine...

International and national organizations have formulated guidelines establishing limits for occupational and residential electromagnetic field (EMF) exposure at high-frequency fields. Italian legislation fixed 20 V/m as a limit for public protection from exposure to EMFs in the frequency range 0.1 MHz-3 GHz and 6 V/m as a reference level. Recently, the law was changed and the reference level must now be evaluated as the 24-hour average value, instead of the previous highest 6 minutes in a day. The law refers to a technical guide (CEI 211-7/E published in 2013) for the extrapolation techniques that public authorities have to use when assessing exposure for compliance with limits...

Informed consent as a model of care has evolved as an alternative to the standard model of care recommended by the World Professional Association for Transgender Health's Standards of Care, version 7, which emphasizes the importance of mental health professionals' role in diagnosing gender dysphoria and in assessing the appropriateness and readiness for gender-affirming medical treatments. By contrast, the informed consent model for gender-affirming treatment seeks to acknowledge and better support the patient's right to, and capability for, personal autonomy in choosing care options without the required involvement of a mental health professional...

The decision concerning the introduction of primary and secondary prophylaxis of venous thromboembolism (VTE) in patients with solid brain neoplasms and brain metastases is often challenging due to the concomitant increased risk of intracranial hemorrhage and to limited evidence from available literature. A standardized questionnaire composed of nine multiple-choice questions regarding primary VTE prevention in non-surgical patients during high-risk conditions and VTE secondary prevention in patients with a solid brain neoplasm or cerebral metastases was sent via electronic mail to all the members (n = 2420) of the Italian Federation of the Internal Medicine Hospital Executives' Associations (FADOI) in June 2015...

The entomopathogenic nematode Steinernema carpocapsae has been widely used for the biological control of insect pests. It shares a symbiotic relationship with the bacterium Xenorhabdus nematophila, and is emerging as a genetic model to study symbiosis and pathogenesis. We obtained a high-quality draft of the nematode's genome comprising 84,613,633 bp in 347 scaffolds, with an N50 of 1.24 Mb. To improve annotation, we sequenced both short and long RNA and conducted shotgun proteomic analyses. S. carpocapsae shares orthologous genes with other parasitic nematodes that are absent in the free-living nematode C...

The effective enforcement of the access to healthcare as fundamental right requires an important theoretical and political effort at linking the often contradictory economic and social dimensions of development. This study suggests the need for a systemic view of policies related to the industrial base and innovation in health and the construction of the Brazilian Unified National Health System (SUS). The authors investigate the relations between health, innovation, and development, seeking to show and update the political, economic, and social determinants of the recent Brazilian experience with the Health Economic-Industrial Complex (HEIC)...

Diverse LiPF6 hydrolysis products evolve during lithium-ion battery cell operation at high operation voltages and high operation temperatures. However, their influence on the electrode/electrolyte interfaces is not yet investigated and understood. In this work, literature-known hydrolysis products of LiPF6 dimethyl fluorophosphate (DMFP) and diethyl fluorophosphate (DEFP) were synthesized and investigated as electrolyte additives. The addition of only 1 wt.% DMFP or DEFP to 1 M LiPF6 in EC:EMC (1:1, by wt.) electrolyte results in improved capacity retention, increased Coulombic efficiencies (CEs) and reduced self-discharge of LiNi1/3Mn1/3Co1/3O2 (NMC111)/Li half cells charged to the elevated upper cut-off potential of 4...

The gold-catalyzed direct functionalization of aromatic C-H bonds has attracted interest for constructing organic compounds which have application in pharmaceuticals, agrochemicals, and other important fields. In the literature, two major mechanisms have been proposed for these catalytic reactions: inner-sphere syn-addition and outer-sphere anti-addition (Friedel-Crafts-type mechanism). In the current article, the AuCl3-catalyzed hydrofurylation of allenyl ketone, vinyl ketone, ketone and alcohol substrates is investigated with the aid of density functional theory calculations and it is found that the corresponding functionalizations are best rationalized in terms of a novel mechanism called "concerted electrophilic ipso-substitution" (CEIS) in which the gold(III)-furyl σ-bond produced by furan auration acts as a nucleophile and attacks the protonated substrate via an outer-sphere mechanism...

The genus Odontophrynus Reinhardt & Lütken comprises 11 species distributed throughout South and East of South America (Frost 2016) clustered in three phenetic groups: O. americanus, O. cultripes, and O. occidentalis (Savage & Cei 1965; Cei 1987; Caramaschi & Napoli 2012). Only the O. occidentalis group is recovered as monophyletic in the most recent phylogenetic hypotheses (Pyron & Wiens 2011; Pyron 2014). In these analyses, the O. cultripes group is not recovered and the monophyly of O. americanus group was not tested, since only one species of the group was included (Pyron & Wiens 2011; Pyron 2014)...

BACKGROUND: There is evidence that administration of a programmed intermittent epidural bolus (PIEB) compared to continuous epidural infusion (CEI) leads to greater analgesia efficacy and maternal satisfaction with decreased anesthetic interventions. METHODS: In this study, 166 women with viable pregnancies were included. After an epidural loading dose of 10mL with Ropivacaine 0.16% plus Sufentanil 10μg, parturient were randomly assigned to one of three regimens: A - Ropivacaine 0...

The study of nanomaterial translocation across epithelial barriers is often hindered by the low permeability of transwell membranes to nanoparticles. To address this issue ultra-thin poly(L-lactic acid) nanofilms with zero tortuosity micropores were developed for use in nanoparticle passage tests. In this study we demonstrate that microporous polymeric nanofilms allow a significantly higher passage of silver nanoparticles in comparison with commercial membranes normally used in Transwell inserts. A robust procedure for collecting free-standing nanofilms which enables their manipulation and use in lab-on-chip systems is described...

Simeprevir is a substrate for organic anion-transporting polypeptides (OATPs) that transport bilirubin. Hyperbilirubinemia is an adverse event reported during treatment of chronic hepatitis C patients with simeprevir plus pegylated interferon and ribavirin. Because gadoxetic acid is also a substrate of OATPs, pretreatment gadoxetic acid-enhanced magnetic resonance imaging (MRI) may predict hyperbilirubinemia during treatment. This prospective study therefore evaluated 11 consecutive patients with chronic hepatitis C who underwent gadoxetic acid-enhanced MRI prior to treatment with simeprevir plus pegylated interferon and ribavirin for 12 weeks, followed by pegylated interferon and ribavirin for an additional 12 weeks...

We report genomes of two species of cactophilic Drosophila: Drosophila arizonae and D. navojoa These two are the closest relatives of D. mojavensis, forming the D. mojavensis cluster. D. mojavensis and D. arizonae diverged from D. navojoa ∼5.8 Mya, while the split between D. arizonae and D. mojavensis is more recent, at 1.5 Mya. Together the three genomes provide opportunities to examine genomic changes associated with speciation and host shifts in this ecologically defined group of flies. The three species are also separated by fixed inversion differences in three of their six chromosomes...
