BACKGROUND AND PURPOSE: Neuroinflammation is initiated by a variety of stimuli including infections, sepsis, neurodegenerative diseases or traumatic brain injury and if not adequately controlled can lead to various degrees of neuronal damage and behavioural impairment. A critical event in the initial steps of inflammation is neutrophil extravasation. Semicarbazide sensitive amine oxidase (SSAO, also known as vascular adhesion protein 1 or VAP-1) regulates neutrophil adhesion and extravasation...

BACKGROUND: Public attitudes toward depression and help-seeking behaviour are important factors influencing depressed people to obtain professional help and adequate treatment. OSPI-Europe is a multi-level suicide prevention programme including a public awareness campaign. It was implemented in four regions of four European countries (Germany, Hungary, Ireland and Portugal). This paper reports the results of the evaluation of the campaign, including its visibility and effects of the campaign on stigma associated with depression and help-seeking behaviour...

Camponotus senex (Fr. Smith 1858) and Camponotus textor Forel, 1899 are commonly confused species in the New World tropics. We provide morphological characteristics based on the larvae and adults, behavioural differences, together with evidence from molecular markers (cuticular hydrocarbon profiles, venom differences, nuclear ribosomal ITS-1, and mtDNA COI sequence comparisons) to separate the two species, demonstrating they are not immediately closely related. In conclusion we suggest new reliable morphological characters which can benefit from deeper phenetic analysis, and support the contextual usefulness of non-morphological tools in resolving sibling ant species...

BACKGROUND: Depression and anxiety disorders are relapse-prone conditions, even after successful treatment with pharmacotherapy or psychotherapy. Cognitive behavioural therapy (CBT) is known to prevent relapse, but there is little evidence of the durability of remission after low intensity forms of CBT (LiCBT). METHOD: This study aimed to examine relapse rates 12 months after completing routinely-delivered LiCBT. A cohort of 439 LiCBT completers with remission of symptoms provided monthly depression (PHQ-9) and anxiety (GAD-7) measures during 12 months after treatment...

A fundamental problem faced by humans is learning to select motor actions based on noisy sensory information and incomplete knowledge of the world. Recently, a number of authors have asked whether this type of motor learning problem might be very similar to a range of higher-level decision-making problems. If so, participant behaviour on a high-level decision-making task could be predictive of their performance during a motor learning task. To investigate this question, we studied performance during an explorative motor learning task and a decision-making task which had a similar underlying structure with the exception that it was not subject to motor (execution) noise...

The lipopeptide surfactin produced by certain strains of Bacillus subtilis is a powerful bio-surfactant possessing potentially useful antimicrobial properties. In order to better understand its surface behaviour, we have used surface sensitive Sum Frequency Generation (SFG) vibrational spectroscopy in the C-H and C=O stretching regions to determine its structure at the air/water interface. Using surfactin with the leucine groups of the peptide ring perdeuterated we have shown that the majority of the SFG signals arise from the 4 leucine residues...

Sequence similarity is a commonly used measure to compare proteins. With the increasing use of ontologies, semantic (function) similarity is getting importance. The correlation between these measures has been applied in the evaluation of new semantic similarity methods, and in protein function prediction. In this research, we investigate the relationship between the two similarity methods. The results suggest absence of a strong correlation between sequence and semantic similarities. There is a large number of proteins with low sequence similarity and high semantic similarity...

This paper aims to improve the interaction and coordination between the human and the robot in cooperative execution of complex, powerful and dynamic tasks. We propose a novel approach that integrates online information about the human motor function and manipulability properties into the hybrid controller of the assistive robot. Through this human-inthe- loop framework, the robot can adapt to the human motor behaviour and provide the appropriate assistive response in different phases of the cooperative task...

Objective Drink driving is widely recognised as a major road safety problem. In Australia, health promotion messages encourage monitoring the number of standard drinks consumed prior to driving. The pilot research aimed to investigate commuting behaviour and blood alcohol concentration (BAC) of diners, including intended-drivers, at Sunshine Coast restaurants. Methods Five hundred and forty-four diners (n = 260 males) consented to participate in a brief interview and to use a breathalyser device to measure their BAC...

OBJECTIVE: The ability to detect changing visual information is a vital component of safe driving. In addition to detecting changing visual information, drivers must also interpret its relevance to safety. Environmental changes considered to have high safety relevance will likely demand greater attention and more timely responses than those considered to have lower safety relevance. The aim of the present study was to explore factors that are likely to influence perceptions of risk and safety regarding changing visual information in the driving environment...

G Paradossi, E Chiessi
The water affinity of poly(N-isopropylacrylamide), PNIPAM, is tuned by tacticity, since the hydrophobicity rises with the increase of the degree of isotacticity. On the basis of this experimental evidence, atomistic molecular dynamics simulations of pairs of PNIPAM stereoisomers in 1.6% w/w polymer aqueous solution, a condition intermediate between the dilute and semidilute regimes, were carried out to comparatively investigate the solution behaviour and hydration of atactic and isotactic-rich PNIPAMs, both below and above the lower critical solution temperature, LCST...

Gas-liquid-solid phase transition behaviour of water is studied with environmental scanning electron microscopy for the first time. Abnormal phenomena are observed. At a fixed pressure of 450 Pa, with the temperature set to -7 °C, direct desublimation happens, and ice grows continuously along the substrate surface. At 550 Pa, although ice is the stable phase according to the phase diagram, metastable liquid droplets first nucleate and grow to ~100-200 μm sizes. Ice crystals nucleate within the large sized droplets, grow up and fill up the droplets...

This study sought to clarify the effects of 15-lipoxygenase/15-hydroxyeicosatetraenoic acid in angiogenesis and neurological functional recovery after cerebral ischaemic stroke in mice. In vivo, we performed behavioural tests to determine functional recovery after stroke. Double immunofluorescence staining of CD31 and Ki67/PCNA was performed to evaluate the effects of 15-lipoxygenase/15-hydroxyeicosatetraenoic acid on angiogenesis in an MCAO mouse model. In vitro, we investigated the effects of 15-hydroxyeicosatetraenoic acid on BMVEC proliferation and migration...

OBJECTIVE: The goal of the study was to examine differential mediation of long-term effects of discrimination on health behaviour and health status by internalising (anxiety and depression) and externalising (hostility and anger), and to explore moderation of these effects, specifically, by the presence of support networks and coping tendencies. DESIGN: The current analyses employed structural equation modelling of five waves of data from Black female participants of the Family and Community Health Study over 11 years (M age 37-48)...

Recommendations for physical activity and for fruit and vegetable intake are often not translated into action due to deficits in self-regulatory strategies. The present study examines the interplay of intention, intergoal facilitation, action and coping planning and self-regulation in facilitating physical activity and healthy nutrition. In an online study, intentions and behaviours were assessed at baseline, intergoal facilitation and planning at 4-week follow-up, self-regulation, physical activity and nutrition at 6-month follow-up in a non-clinical sample...

The present study explores whether sleep concerns are associated with wish to die throughout a 1-month time interval following a suicide crisis. Sixty-eight patients admitted to the emergency department of a general or psychiatric hospital were enrolled. Sleep difficulties were assessed using the Insomnia Severity Index (ISI), the Epworth Sleepiness Scale, self-reported satisfaction with sleep and time in bed. Suicidal ideation was assessed through the presence of a wish to die at 1 month following a suicide crisis...

Personality research has been focused on different aspects of the self, including traits, attitudes, beliefs, goals, and motivation. These aspects of the self are used to explain and predict social behaviour. The present research assessed generalized beliefs about the world, termed 'social axioms' (Leung et al., ), and examined their additive power over beliefs about the self in explaining a communal behaviour, that is, modesty. Three studies predicted reported modest behaviour among Mainland Chinese, Hong Kong Chinese, East Asian Canadians, and European Canadians...

BACKGROUND: Dilated cardiomyopathy (DCM) can be caused by mutations in sarcomeric and non-sarcomeric genes. In this study we defined the pathogenic effects of three DCM causing mutations: the sarcomeric mutations in genes encoding cardiac troponin I (TNNI3p.98truncation ) and cardiac troponin T (TNNT2p.K217deletion ; also known as the K210del) and the non-sarcomeric gene mutation encoding lamin A/C (LMNAp.R331Q ). METHODS: We assessed sarcomeric protein expression and phosphorylation and contractile behaviour in single membrane-permeabilized cardiomyocytes in human left ventricular heart tissue...

We demonstrate that a bipolar non-volatile resistive switching behaviour with negative differential resistance (NDR) effect is realized in a Cu/BaTiO3/Ag device, which was deposited on a Si substrate via magnetron sputtering equipment. We suggest that the bipolar resistive switching is dominated by the trapping/detrapping of electrons at the BaTiO3-Cu interface. In addition, we demonstrate that the device exhibits good performance, including a large on/off ratio, high reliability and long retention time. Therefore, BaTiO3 may become a good candidate for application in resistive switching random access memory (RRAM) devices...
