The aim of this research was to evaluate the welfare of pre-weaned piglets euthanised using three different gas treatments: 100% carbon dioxide (CO₂), 100% argon (Ar) or a mixture of 60% Ar/40% carbon dioxide (Ar/CO₂). Two studies (n = 5 piglets/treatment/study) were conducted: (1) behavioural and physiological data were collected from conscious piglets during exposure to test gases via immersion in a pre-filled chamber and (2) electrophysiological data were collected from lightly anaesthetised, intubated and mechanically ventilated piglets exposed to the same test gases...

The resistive switching properties of silicon-aluminium oxynitride (SiAlON) based devices have been studied. Electrical transport mechanisms at both resistance states were determined, exhibiting an ohmic behaviour at low resistant state and a defect-related Poole-Frenkel mechanism at high resistant state. Nevertheless, some features on the Al top-electrode are generated during the initial electroforming, suggesting some material modifications. An in-depth microscopic study at the nanoscale have been performed after the electroforming process, by acquiring scanning electron microscopy and transmission electron microscopy images...

Background: Approximately 17% of the European workforce is engaged in shift work. How the experience of shift work impacts on the dietary and lifestyle practices of workers is unclear. Methods: Overall, 15 focus groups were conducted by two researchers, with 109 participants. The initial focus group was carried out with both researchers present, to ensure consistency in facilitation. Both researchers thematically analysed all data collected. Results: Shift work was described as affecting many areas of workers' lives...

The biochemical and behavioral responses to prenatal and early postnatal exposure to paracetamol in rats are not well understood. The effect of daily maternal and early life administration of 5 mg/kg (group P5) or 15 mg/kg paracetamol (group P15) was evaluated in two-month old male rats, relative to control animals receiving tap water (Con). Social behavior and episodic memory were investigated with Social Interaction and Novel Object Recognition (NOR) tests. Quantification of brain-derived neurotrophic factor (BDNF) was determined in prefrontal cortex, hippocampus and striatum using enzyme-linked immunosorbent assay (ELISA)...

Fishes are the first group of vertebrates that respond when the environment is contaminated with pollutants resulted from anthropogenic activities. The development of the toxicity tests is bringing new evidence about the toxicological effects of the pollutants upon the life forms. Behavioural abnormalities in the swimming performance and cognitive processes were well associated with the response of organisms to pollutants from environment. The aim of the paper was to study the behavioural changes of zebrafish (memory, swimming performances and aggression) and oxidative stress (superoxide dismutase and malondialdehyde) during 32 h of acute exposure with methylmercury (II) chloride to measure its neurotoxicity effects upon fish community...

In-vehicle collision avoidance technology (CAT) has the potential to prevent crash involvement. In 2015, Transport for New South Wales undertook a trial of a Mobileye 560 CAT system that was installed in 34 government fleet vehicles for a period of seven months. The system provided headway monitoring, lane departure, forward collision and pedestrian collision warnings, using audio and visual alerts. The purpose of the trial was to determine whether the technology could change the driving behaviour of fleet vehicle drivers and improve their safety...

Although several studies have demonstrated a potential correlation of dietary patterns with cognitive function, the relationship between tooth loss and dietary patterns and cognitive function have not been identified. In this cross-sectional study, we used a reduced rank regression (RRR) analysis, a technique used previously to observe dietary patterns based on the intakes of nutrients or levels of biomarkers associated with the condition of interest, to identify tooth loss-related dietary patterns and investigate the associations of such patterns with cognitive impairment in 334 community-dwelling Japanese subjects aged ≥ 60 years...

Sedentary behaviour is increasing due to societal changes and is related to prolonged periods of sitting. There is sufficient evidence proving that sedentary behaviour has a negative impact on people's health and wellness. This paper presents our research findings on how to mine the temporal contexts of sedentary behaviour by utilizing the on-board sensors of a smartphone. We use the accelerometer sensor of the smartphone to recognize user situations (i.e., still or active). If our model confirms that the user context is still, then there is a high probability of being sedentary...

Background: Condoms remain the main protection against sexually transmitted infections (STIs) when used correctly and consistently. Yet, there are many reported barriers to their use such as negative attitudes, reduced sexual pleasure, fit-and-feel problems and erection difficulties. The UK home-based intervention strategy (HIS-UK) is a behaviour change condom promotion intervention for use among young men (aged 16-25 years) designed to increase condom use by enhancing enjoyment of condom-protected intercourse...

Within populations, individuals can vary in stress response, a multivariate phenomenon comprising neuroendocrine, physiological and behavioural traits.Verbal models of individual stress "coping style" have proposed that the behavioural component of this variation can be described as a single axis, with each individual's coping style being consistent across time and stress contexts.Focusing on this behavioural component of stress response and combining repeated measures of multiple traits with a novel multivariate modelling framework, we test for the existence of coping style variation and assess its stability across contexts in the Trinidadian guppy ( Poecilia reticulata )...

Substance abuse is a family disease that adversely impacts both the user and the user's family. The family can act as a risk factor for the development of substance abuse among children and adults. The family can also be involved in therapy to either help the recovery process or prevent substance abuse. Marital and family therapy have been found to be effective in reducing the severity of substance use, lowering marital and family conflict, improving family communication and cohesion as well as effective parenting practices...

In socials insects, exploration is fundamental for the discovery of food resources and determines decision-making. We investigated how the interplay between the physical characteristics of the paths leading to food sources and the way it impacts the behaviour of individual ants affects their collective decisions. Colonies of different sizes of Lasius niger had access to two equal food sources through two paths of equal length but of different geometries: one was straight between the nest and the food source, and the other involved an abrupt change of direction at the midway point (135°)...

Increasing HIV testing rates among high-risk groups should lead to increased numbers of cases being detected. Coupled with effective treatment and behavioural change among individuals with detected infection, increased testing should also reduce onward incidence of HIV in the population. However, it can be difficult to predict the strengths of these effects and thus the overall impact of testing. We construct a mathematical model of an ongoing HIV epidemic in a population of gay, bisexual and other men who have sex with men...

Fertility levels and their determinants in Saudi Arabia have not been studied sufficiently for formulating family policy, although some attention has been paid to rapid fertility transitions in the context of socioeconomic and cultural change. This study focused on the fertility of a particular occupational category in the Kingdom of Saudi Arabia to assess determinants of fertility, measured as the number of children. The sample was drawn from the King Saud University staff - ever-married Saudi Arabian women...

BACKGROUND: A neurobiologically informed, system-specific psychopathological approach has been suggested for use in schizophrenia. However, to our knowledge, such an approach has not been used to prospectively describe the course of schizophrenia. SAMPLING AND METHODS: We assessed psychopathology in a well-described sample of 100 patients with schizophrenia or schizoaffective disorder with the Bern Psychopathology Scale (BPS) at 6-month intervals for up to 18 months...

OBJECTIVES: Reinforcements for the pulmonary autograft (PA) in the Ross operation have been introduced to avoid the drawback of conduit expansion and failure. With the aid of an in silico simulation, the biomechanical boundaries applied to a healthy PA during the operation were studied to tailor the best implant technique to prevent reoperation. METHODS: Follow-up echocardiograms of 66 Ross procedures were reviewed. Changes in the dimensions and geometry of reinforced and non-reinforced PAs were evaluated...

Universal health coverage (UHC) has been adopted by many countries as a national target for 2030. People with disabilities need to be included within efforts towards UHC, as they are a large group making up 15% of the world's population and are more vulnerable to poor health. UHC focuses both on covering the whole population as well as providing all the services needed and must include an emphasis on health promotion, as well as disease treatment and cure. Health promotion often focusses on tackling individual behaviours, such as encouraging exercise or good nutrition...

We have previously reported the effects of intracranial injections of dopamine D1, D2 and D3 ligands in animals subjected to the Novel Object Recognition (NOR) test following exposure to chronic mild stress (CMS) and chronic treatment with risperidone (RSP). Here, we present some molecular biological data from the same animals. It was predicted that brain-derived neurotrophic factor (BDNF) signalling in the prefrontal cortex (PFC) would reflect behavioural performance, implying an increase following acute administration of a D2 agonist or a D3 antagonist, blockade of this effect by CMS and its restoration by chronic RSP...
