Among tick species, members of the subfamily Amblyomminae have received special attention, since they serve as vectors for pathogens such as Rickettsia spp. and display cryptic species complexes that make their taxonomical classification challenging. Amblyomma ovale, Amblyomma maculatum, and other species of the genus Amblyomma have shown a long history of taxonomic controversies. Spermiotaxonomy has proved to be a valuable tool in the solution of systematic conflicts in Metazoa that can aid molecular and external morphological analyses in ticks and, overall, provide more robust analyses and results...

There is a continuing debate about control of voluntary movement, with conflicted evidence about the balance between control of movement vectors (amplitude control) that implies knowledge of the starting position for accuracy, and equilibrium point or final position control, that is independent of the starting conditions. We tested wrist flexion and extension movements in a man with a chronic peripheral neuronopathy that deprived him of proprioceptive knowledge of his wrist angles. In a series of experiments, we demonstrate that he could scale the amplitude of his wrist movements in flexion/extension, even without visual feedback, and appeared to adopt a strategy of moving via a central wrist position when asked to reach target angles from unknown start locations...

Binge eating disorder (BED) is defined as recurrent, distressing over-consumption of palatable food (PF) in a short time period. Clinical studies suggest that individuals with BED may have impairments in cognitive processes, executive functioning, impulse control, and decision-making, which may play a role in sustaining binge eating behavior. These clinical reports, however, are limited and often conflicting. In this study, we used a limited access rat model of binge-like behavior in order to further explore the effects of binge eating on cognition...

It is increasingly recognized that the abnormal physiologic consequences of pulmonary hypertension (PH) may contribute to poor cardiopulmonary health in premature babies. Conflicting literature has led to clinical uncertainty, pathological misinterpretation and variability in treatment approaches among practitioners. There are several disorders with overlapping and interrelated presentations and other disorders with a similar clinical phenotype but diverse pathophysiological contributors. In this review, we provide a diagnostic approach for acute HRF in the preterm neonate, outline the pathophysiological conditions that may present as acute PH and discuss the implications of high pulmonary vascular resistance (PVR) on the cardiovascular system...

INTRODUCTION: Errors and notices to appear in court are a reality of life for many midwives and exert significant effects on both their professional and personal lives. Given the increasing population policies in place, this study was conducted to examine midwives' experiences of litigation in Iran. METHODS: A qualitative study was conducted in 2014 using an interpretive phenomenological approach. The interviews were recorded and transcribed and were then analyzed using the Diekelmann method...

This study examined the effects of dual identity conflict, religious identity (religious/spiritual vs. sexual), and partnership status on the coping strategies and mental health of gay Jewish men in modern Israeli society. Participants were 73 religious and 71 secular gay men recruited via email, social networking sites, and online resources targeting sexual minority men. Participants were assessed via measures of identity conflict, mental health, and coping strategies. Jewish gay men who reported more severe identity conflict also reported using less problem-focused, emotion-focused, and avoidance coping strategies and reported poorer mental health than their less identity-conflicted counterparts...

The aim is to achieve a transgenerational view of single motherhood in Spain, to look at which contexts it arises in, how it changes with the introduction of assisted reproduction, and how the role of religion in Spanish society permeates medical practice and affects the lives of women patients. I examine single motherhood and investigate two interconnected themes: a) being a mother and being mothered are both permeated with socio-cultural, political, religious, economic and psychological significance; b) Spain led Europe in multiple births due to assisted reproduction, thus ethical conflicts and patient rights are analysed...

This study examined the unique roles of support and conflict in the relationship with the mother and the father in predicting changes in adolescents' depressive symptoms over a 1-year period. Potential moderating effects of genetic factors (Gene × Environment interaction) and sex were also investigated. This study utilized a design of twins raised in the same family, based on a sample of 121 monozygotic and 88 dizygotic same-sex twin pairs (418 individuals; 52.2% girls) assessed in Grade 8 (M = 14.09, SD = ...

REVIEW
Shaoli Lin, Yan-Jin Zhang
Hepatitis B virus (HBV) causes liver diseases that have been a consistent problem for human health, leading to more than one million deaths every year worldwide. A large proportion of hepatocellular carcinoma (HCC) cases across the world are closely associated with chronic HBV infection. Apoptosis is a programmed cell death and is frequently altered in cancer development. HBV infection interferes with the apoptosis signaling to promote HCC progression and viral proliferation. The HBV-mediated alteration of apoptosis is achieved via interference with cellular signaling pathways and regulation of epigenetics...

Patients' requests for non-indicated cesarean delivery challenge the professionalism of obstetricians. This is because physicians should not provide clinical management in the absence of an evidence-based indication for it. The ethics of responding professionally to requests for non-indicated cesarean delivery would appear to be simple: just say "No." This paper presents an ethically and clinically more nuanced approach, on the basis of the professional responsibility model of obstetric ethics, emphasizinga preventive ethics approach...

Previous studies that have investigated the association between B-vitamin supplement use and risk for cataract yield conflicting results. The aim of this study was to examine the association between use of high-dose B-vitamin supplements (approximately 10 times recommended daily intake) and risk for age-related cataract in a population-based prospective study of 13 757 women from the Swedish Mammography Cohort and 22 823 men from the Cohort of Swedish Men. Dietary supplement use and potential confounders were assessed using a questionnaire at baseline...

As early diagnosis of swallowing and feeding difficulties in infants and children is of utmost importance, there is a need to evaluate the quality of the psychometric properties of pediatric assessments of swallowing and feeding. A systematic review was performed summarizing the psychometric properties of non-instrumental assessments for swallowing and feeding difficulties in pediatrics; no data were identified for the remaining twelve assessments. The COSMIN taxonomy and checklist were used to evaluate the methodological quality of 23 publications on psychometric properties...

BACKGROUND: Continuous monitoring of cerebral autoregulation is considered clinically useful due to its ability to warn against brain ischemic insults, which may translate to a relationship with adverse outcome. It is typically performed using the pressure reactivity index (PRx) based on mean arterial pressure and intracranial pressure. A new ORx index based on brain tissue oxygenation and cerebral perfusion pressure (CPP) has been proposed that similarly allows for evaluation of cerebrovascular reactivity...

In contrast to a wealth of human studies, little is known about the ontogeny and consistency of empathy-related capacities in other species. Consolation-post-conflict affiliation from uninvolved bystanders to distressed others-is a suggested marker of empathetic concern in non-human animals. Using longitudinal data comprising nearly a decade of observations on over 3000 conflict interactions in 44 chimpanzees (Pan troglodytes), we provide evidence for relatively stable individual differences in consolation behaviour...

Diverse RNA transcripts acting as competing endogenous RNAs (ceRNAs) can co-regulate each other's expression by competing for shared microRNAs. CCR2 protein, the receptor of CCL2, is implicated in cancer progression. However, our results showed that higher CCR2 mRNA level was remarkably associated with prolonged survival of breast cancer patients. The conflicting results prompt us to study the non-coding function of CCR2 mRNA. We indicated that CCR2 3'UTR inhibited MDA-MB-231 and MCF-7 cells metastasis by repressing EMT in vitro and suppressed breast cancer metastasis in vivo Mechanistically, CCR2 3'UTR modulated RhoGAP protein STARD13 expression via acting as a STARD13 ceRNA in a microRNA-dependent and protein coding-independent manner...

REVIEW
John A Frank, Cédric Feschotte
Eukaryotic genomes are littered with sequences of diverse viral origins, termed endogenous viral elements (EVEs). Here we used examples primarily drawn from mammalian endogenous retroviruses to document how the influx of EVEs has provided a source of prefabricated coding and regulatory sequences that were formerly utilized for viral infection and replication, but have been occasionally repurposed for cellular function. While EVE co-option has benefited a variety of host biological functions, there appears to be a disproportionate contribution to immunity and antiviral defense...

BACKGROUND CONTEXT: Smartphones have become an integral tool in the daily life of healthcare professionals (Franko 2011). Their ease of use and wide availability often make smartphones the first tool surgeons use to perform measurements. This technique has been validated for certain orthopaedic pathologies (Shaw 2012, Quek 2014, Milanese 2014, Milani 2014), but never to assess sagittal parameters in adult spinal deformity. This study was designed to assess the validity, reproducibility, precision and efficiency of using a smartphone protractor application to measure sagittal parameters commonly measured in adult spinal deformity assessment and surgical planning...

BACKGROUND: Measuring and monitoring progress towards Millennium Development Goals (MDG) 4 and 5 requires valid and reliable estimates of maternal and neonatal mortality. In South Africa, there are conflicting reports on the estimates of maternal and neonatal mortality, derived from both direct and indirect estimation techniques. This study aims to systematically review the estimates made of maternal and neonatal mortality in the period from 1990 to 2015 in South Africa and determine trends over this period...
