Background People living with dementia often develop distressing behavioural and psychological symptoms (BPSD) that can affect their quality of life and the capacity of family carers and staff providing support at home. This systematic review of qualitative studies considers the views and experiences of people living with dementia and care providers about these symptoms and what helps to reduce their impact. Methods The two-stage review involved (a) An initial mapping of the literature to understand the range of BPSD, and how it is operationalised by different groups, to develop a search strategy; (b) A search of electronic databases from January 2000 to March 2015, updated in October 2016...

Chirality is ubiquitous in nature and plays crucial roles in biology, medicine, physics and materials science. Understanding and controlling chirality is therefore an important research challenge with broad implications. Unlike other chiral colloids, such as nanocellulose or filamentous viruses, amyloid fibrils form nematic phases but appear to miss their twisted form, the cholesteric or chiral nematic phases, despite a well-defined chirality at the single fibril level. Here we report the discovery of cholesteric phases in amyloids, using β-lactoglobulin fibrils shortened by shear stresses...

Background: Latin America and the Caribbean (LAC) countries, have been historically under-represented due to the lack of surveillance of physical behaviours in young populations. Therefore, the aim of this study was to describe and compare overall physical activity (PA), active transportation to and from school (i.e. walking or cycling), physical education (PE) participation, and sedentary behaviour (SB) in adolescents from 26 countries in LAC. Methods: Data were collected in the Global School-based Student Health Survey (2007-13)...

Preventing HIV among young people is critical to achieving and sustaining global epidemic control. Evidence from Western settings suggests that family-centred prevention interventions may be associated with greater reductions in risk behaviour than standard adolescent-only models. Despite this, family-centred models for adolescent HIV prevention are nearly non-existent in South Africa - home to more people living with HIV than any other country. This paper describes the development and formative evaluation of one such intervention: an evidence-informed, locally relevant, adolescent prevention intervention engaging caregivers as co-participants...

BACKGROUND: Universities' responsibility to ensure academic integrity is frustrated by software and communication tools that facilitate content reuse coupled with a growing international essay writing economy. A wide range of behaviours constitute academic dishonesty and while a complex phenomenon to examine, existing evidence suggests that there is sufficient proliferation (both in volume and variety) of these behaviours among Australian university students to warrant concern. This proliferation presents faculty and staff with new challenges in ensuring academic integrity...

Metastasis remains the greatest challenge in the clinical management of cancer. Cell motility is a fundamental and ancient cellular behaviour that contributes to metastasis and is conserved in simple organisms. In this Review, we evaluate insights relevant to human cancer that are derived from the study of cell motility in non-mammalian model organisms. Dictyostelium discoideum, Caenorhabditis elegans, Drosophila melanogaster and Danio rerio permit direct observation of cells moving in complex native environments and lend themselves to large-scale genetic and pharmacological screening...

Quantum dot (QD)-decorated semiconductor micro- and nanoparticles are a new class of functional nanomaterials that have attracted considerable interest for their unique structural, optical and electronic properties that result from the large surface-to-volume ratio and the quantum confinement effect. In addition, because of QDs' excellent light-harvesting capacity, unique photoinduced electron transfer, and up-conversion behaviour, semiconductor nanoparticles decorated with quantum dots have been used widely in photocatalytic applications for the degradation of organic pollutants in both the gas and aqueous phases...

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...

Though James Lind is renowned as a pioneer of the clinical trial, he records the 1747 trial aboard the Salisbury in passing, never followed up on it, never campaigned for clinical trials as a means of medical discovery, and eventually pronounced scurvy an insoluble enigma. The case can be made that in confessing his lack of an unfailing remedy for scurvy and his trouble making sense of the disease's behaviour, Lind did medicine a greater service than by conducting his now-famous trial. At the time, medical progress was hindered by the all-too-common practice of proclaiming success and concealing failure...

Many fish species face increasing challenges associated with climate change and overfishing. At the same time, aquaculture is becoming vital for food security. Gaining a deeper understanding of the basic biology of fish is therefore more important than ever. Here we synthesize and summarize key questions, opportunities and challenges in fish biology highlighted during a round-table discussion at the 50th Anniversary Symposium of The Fisheries Society of the British Isles, held at the University of Exeter, U...

Background: Aphasia is an acquired impairment in language and in the cognitive processes that underlie language. Aphasia affects the quality of life of the person with aphasia (PWA) and his or her families in various ways in diverse contexts and cultures. It is therefore important that speech language therapists understand how different contextual and cultural factors may mediate experiences. Purpose: The aim of the study was to describe the caregiving experience of female caregivers of PWA residing in Tembisa, a township situated in the east of Johannesburg...

Building on previous work in the field, we examined the effect of maternal high fat diet (HFD) during gestation and lactation on the sensitivity of male and female adult offspring to acute and repeated cocaine exposures, and to the expression of cocaine-induced anxiety in the elevated plus maze (EPM). In both male and female offspring, acute injections of cocaine induced a strong locomotor-activating effect; repeated injections produced a robust conditioned locomotor response to the context in which they were given cocaine, and heightened activity in response to a subsequent acute challenge of cocaine...

BACKGROUND: Despite the potential population-level impact of a health-promoting schools approach, schools face challenges in implementation, indicating a gap between school health research and practice. Knowledge exchange provides an opportunity to reduce this gap; however, there has been limited evaluation of these initiatives. This research explored researchers' and knowledge users' perceptions of outcomes associated with a knowledge exchange initiative within COMPASS, a longitudinal study of Canadian secondary students and schools...
