BACKGROUND: Changes in nursing students' expectations of their clinical nursing faculty competences over the course of time are an insufficiently researched phenomenon. OBJECTIVES: To explore what competences BSc nursing students expect from their clinical faculties during their clinical training, and whether their expectations changed during their three-year studies. Furthermore, to survey factors which influenced their expectations and whether the fulfilment levels of their expectations influenced their feelings, learning, and behaviour...

In mammals, faithful inheritance of genomic methylation patterns ensures proper gene regulation and cell behaviour, impacting normal development and fertility. Following establishment, genomic methylation patterns are transmitted through S-phase by the maintenance methyltransferase Dnmt1. Using a protein interaction screen, we identify Microprocessor component DROSHA as a novel DNMT1-interactor. Drosha-deficient embryonic stem (ES) cells display genomic hypomethylation that is not accounted for by changes in the levels of DNMT proteins...

Donggutuo (DGT) is one of the richest archaeological localities in the Nihewan Basin of North China, thereby providing key information about the technological behaviours of early hominins in eastern Asia. Although DGT has been subject of multiple excavations and technological studies over the past several decades, few detailed studies on the lithic assemblages have been published. Here we summarize and describe the DGT lithic assemblages, examining stone tool reduction methods and technological skills. DGT dates to ca...

Jonathan A Kemp
The physics of wound and unwound strings on the electric guitar are presented here, and the pitch intervals produced by the movements of a Fender Stratocaster tremolo unit are explained. Predicted changes in pitch sensitivity of different strings are given, and experimentally verified, for changes in saddle height, the distance of string free to move behind the nut and ratio of diameters/masses of the core and windings of wound strings. Also, it is shown that changes to the gauge of strings (assuming the string tension is sufficient for linear behaviour and in absence of changes to other construction details) don't alter the pitch intervals produced by a given angle of tremolo arm use assuming the instrument is set up with the same sounding pitches and starting bridge angle...

BACKGROUND: Exploring ways to improve the trajectory and symptoms of autism spectrum disorder is prevalent in research, but less is known about the natural prognosis of autism spectrum disorder and course of symptoms. The objective of this study was to examine the temporal stability of autism spectrum disorder and autism diagnosis, and the longitudinal trajectories of autism core symptom severity. We furthermore sought to identify possible predictors for change. METHODS: We searched PubMed, PsycInfo, EMBASE, Web of Science, Cochrane Library up to October 2015 for prospective cohort studies addressing the autism spectrum disorder/autism diagnostic stability, and prospective studies of intervention effects...

Pregnancy is a period of psychological change which may lead to difficulties of adaptation and psychological suffering and give rise to high-risk behaviours for the fœtus in pregnant women. These risk behaviours, which are defined by certain authors as a form of "maltreatment" of the fœtus, usually spring from the psychological distress of the pregnant woman but are not recognised as a specific medical disorder. We illustrate the difficulties encountered in the identification of, and the specific intervention in, these situations through the clinical case of a pregnant drugs-dependent patient subjected to several stress factors who, in addition to consuming substances, developed high-risk behaviours for herself and her pregnancy: self-endangerment under the influence of substances, falls or refusals of treatment...

Tomáš Pluskal, Jing-Ke Weng
Humans perceive physical information about the surrounding environment through their senses. This physical information is registered by a collection of highly evolved and finely tuned molecular sensory receptors. A multitude of bioactive, structurally diverse ligands have evolved in nature that bind these molecular receptors. The complex, dynamic interactions between the ligands and the receptors lead to changes in our sensory perception or mood. Here, we review our current knowledge of natural products and their derived analogues that interact specifically with human G protein-coupled receptors, ion channels, and nuclear hormone receptors to modulate the sensations of taste, smell, temperature, pain, and itch, as well as mood and its associated behaviour...

AIM: This paper examines appeal to fear in general: its perceived positive aspects, its negative characteristics, its appropriate as well as its fallacious use. BACKGROUND: Appeal to fear is a commonly used marketing method that attempts to change behaviour by creating anxiety in those receiving a fearful message. It is regularly used in public health initiatives such as anti-smoking, anti-drunk driving campaigns as well as in hypertension awareness campaigns. Some chiropractors appear to use appeal to fear to promote subluxation awareness and thereby encourage the use of chiropractic treatment...

OBJECTIVES: We examined the relationship between a physical activity monitor, which measures physical activities and health behavioural factors, and behavioural changes in 70 first-year university students who consented to participate among 80 students (recovery rate, 87.5%). METHODS: We evaluated Pearson's correlation coefficients using the Mann-Whitney U-test for changes in health behavioural factors and self-efficacy and performed binomial logistic regression analysis with health behavioural factors and self-efficacy as dependent variables and life improvement effects as explanatory variables...

In cooperative breeders, aggression from dominant breeders directed at subordinates may raise subordinate stress hormone (glucocorticoid) concentrations. This may benefit dominants by suppressing subordinate reproduction but it is uncertain whether aggression from dominants can elevate subordinate cooperative behaviour, or how resulting changes in subordinate glucocorticoid concentrations affect their cooperative behaviour. We show here that the effects of manipulating glucocorticoid concentrations in wild meerkats (Suricata suricatta) on cooperative behaviour varied between cooperative activities as well as between the sexes...

When the immune system responds to tumour development, patterns of immune infiltrates emerge, highlighted by the expression of immune checkpoint-related molecules such as PDL1 on the surface of cancer cells. Such spatial heterogeneity carries information on intrinsic characteristics of the tumour lesion for individual patients, and thus is a potential source for biomarkers for anti-tumour therapeutics. We developed a systems biology multiscale agent-based model to capture the interactions between immune cells and cancer cells, and analysed the emergent global behaviour during tumour development and immunotherapy...

Inappropriate prescribing of antibiotics for the management of respiratory tract infections (RTIs) has contributed to increased prevalence of antibiotic resistance, and this remains a challenge. The aim of this study was to evaluate the effect of general practitioners' (GPs) participation in the Antibiotics: Clinical e-Audit, a quality-improvement activity, on GP self-reported knowledge and practice change, and explored barriers encountered in the management of respiratory tract infections (RTIs). Participants completed a survey at the end of the activity to assess the usefulness of the audit, any reported changes made and barriers encountered to their clinical practice...

BACKGROUND: The choice and appropriate use of animal models in drug discovery for Alzheimer's disease (AD) is pivotal to successful clinical translation of novel therapeutics, yet true alignment of research is challenging. Current models do not fully recapitulate the human disease, and even exhibit various degrees of regional pathological burden and diverse functional alterations. Given this, relevant pathological and functional endpoints must be determined on a model-by-model basis. The present work explores the rTg4510 mouse model of tauopathy as a case study to define best practices for the selection and validation of cognitive and functional endpoints for the purposes of pre-clinical AD drug discovery...

Background: Gap year travellers can potentially be exposed to many infectious diseases and other travel-related health problems including injuries and psychological problems. Currently, there is little information on health and wellbeing of this particular group of travellers. Methods: Participants were recruited from an organization that specialized in organising international gap year placements. Gap year travellers were asked to complete a pre-departure survey on demographics, placement destination and duration, previous travel experience, hobbies, risk taking behaviour, anticipated problems during the placement, and pre-travel preparations...

The tumour immune microenvironment is considered to influence cancer behaviour and outcome. Using a panel of markers for innate and adaptive immune cells we set out to characterise and understand the bladder tumour microenvironment of 114 patients from a prospective multicentre cohort of newly-diagnosed bladder cancer patients, followed-up for 4.33±1.71 years. We found IL-17-positive cells were significantly increased in primary and concomitant carcinoma in situ (CIS), p<0.0001, a highly malignant lesion which is the most significant single risk factor for disease progression...

In the wake of transformational change powered by the digital era, resultant leadership challenges and strategies essential for successful change, both tactical and cultural, are linked to defined capabilities within the Systems Transformation domain of the LEADS in a Caring Environment framework. Honed from experience, specific softer leadership behaviours supporting system transformation are both described and reinforced. Further, a matrix combining the LEADS framework capabilities with these more specific behaviours is offered as a planning tool that leaders may reflect upon and map out key activities associated with their sponsorship of significant change...

Science lies nowadays in the centre of several storms. The better known is the finding of non-reproducibility of many scientific results, which stretches from the medical field (clinic and pre-clinic tests) to study on behaviour (priming research). Although the bad use of statistics is reported to be a patent cause of the reproducibility crisis, its deep reasons are to be sought elsewhere; particularly, in the passage from a regimen of little science - regulated by small communities of researchers - to the current big science - identified by a hypertrophic production of millions of research papers and by the imperative "publish or perish", in a setting dominated by market...

BACKGROUND: Mothers of children with autism spectrum disorder (ASD) report high levels of stress and lower levels of well-being than parents of typically developing children. Current interventions for ASD typically focus on working with the child rather than delivering strategies to help support parents. OBJECTIVE: To evaluate the effectiveness of a psychoeducation intervention developed to support mothers of children with ASD in Saudi Arabia. METHOD: Sixty-two mothers (23-52 years) of children (26-78 months) were recruited to a multisite randomized controlled trials of the intervention...

Engaging young people in the design and delivery of mental health education could lead to more effective interventions; however, few of these interventions have been evaluated. This study aimed to gain preliminary evidence with regards to the efficacy and acceptability of OpenMinds: a peer-designed and facilitated mental health literacy programme for university and secondary school students. The programme involves a structured programme of education and training for university medical students, who then deliver workshops in secondary schools...
