Concord Grape Juice, cognitive function and driving performance: a 12 week, placebo controlled, randomised, crossover trial in mothers of pre-teen children

Background: Daily consumption of Concord grape juice (CGJ) over three to four months has been shown to improve memory function in adults with mild cognitive impairment, and reduce blood pressure in hypertensive adults. These benefits are likely due to the high concentration of polyphenols in CGJ. Increased stress can impair cognitive function and elevate blood pressure. Thus we examined the potential beneficial effect of CGJ in individuals experiencing somewhat stressful demanding lifestyles. Objective: To examine the effects of twelve weeks’ daily consumption of CGJ on cognitive function, driving performance, and blood pressure in healthy, middle-aged working mothers. Design: Twenty five healthy mothers of pre-teen children, aged 40-50 years, who were employed for > 30 hours/week consumed 12oz (355ml) CGJ (containing 777mg total polyphenols) or an energy, taste and appearance matched placebo daily for twelve weeks according to a randomised, crossover design with a four week washout. Verbal and spatial memory, executive function, attention, blood pressure and mood were assessed at baseline, six weeks and twelve weeks. Immediately following the cognitive battery, a subsample of seventeen females completed a driving performance assessment in the University of Leeds Driving Simulator. The twenty five minute driving task required participants to match the speed and direction of a lead vehicle. Results: Significant improvements in immediate spatial memory and driving performance were observed following CGJ relative to placebo. There was evidence of an enduring effect of CGJ such that participants who received CGJ in arm 1 maintained better performance in the placebo arm. Conclusions: Cognitive benefits associated with chronic consumption of flavonoid-rich grape juice are not exclusive to adults with mild cognitive impairment. Moreover, these cognitive benefits are apparent in complex everyday tasks such as driving. Effects may persist beyond cessation of flavonoid consumption and future studies should carefully consider the length of washout within crossover designs.

Leucine supplementation favors liver protein status but does not reduce body fat in rats during 1 week of food restriction

An important role in protein-energy metabolism has been attributed to leucine because of its long-term effects on body fat reduction and on the improvement of some indicators of protein status in rodents. The present study investigated the influence of leucine supplementation on the body composition and protein status of rats during the early phase of weight loss, which is characterized by a rapid loss of body weight. Thirty adult male Wistar rats were divided into 2 groups, a control and a leucine group (diet supplemented with 0.59% L-leucine), and were submitted to 1 week of 50% food restriction. The following parameters were evaluated: chemical carcass composition, protein and RNA content in liver and gastrocnemius muscle, and serum concentrations of insulin-like growth factor-1 and corticosterone. A higher liver weight and liver protein content were observed in the supplemented group (p < 0.05). However, no difference in body fat was found between groups (p > 0.05). The results indicate that low-dose leucine supplementation favors liver protein status but does not reduce body fat in rats during the early phase of rapid weight loss.

Sveta Bogorodica (The Church of the Holy Mother), Zavoj, Macedonia : writing about an insignificant vernacular building

Sveta Bogorodica (Church of the Holy Mother), Zavoj, is a small church built in 1934 in a village in the Republic of Macedonia. It presented a quintessential architectural division between a richly ornamented interior and a pure white formal exterior. The paper will examine the question of tradition in relation to architecture. What of the formal Byzantine architectural tradition is inherited in this folk vernacular church building? Secondly, tradition as an inherited liturgical ritual and ceremony. How are these two forms of tradition autonomous or intertwined, and how the question about transcendence in architecture pursued in the 2005 paper on Hagia Sofia might be understood within the parameters offered by this church building, will be explored in the paper .

Rural Health Week Tasmania 2007

Aims & Rationale/Objectives
To raise the awareness of health issues in rural Tasmania, the work of rural health professionals and community volunteers

Methods
A partnership initiative between the University Department of Rural Health and the Department of Health and Human Services attracted $64,000 sponsorship from government and private sector. It established 28 regional groups which organised local activities and awards for a community volunteeer and a health professional. Regional groups were surveyed about their planning process for rural health week, the activities held, their outcomes and future intentions.

Principal Findings
Regional groups were partnerships of local organisations. Activities had a preventative focus. They included cooking, bike rides, dances, manual handling, health checks, community art, suicide prevention.Events attracted up to 300 participants. There were 48 nominations for the 2 awards, which were perceived to have raised the profile of health professionals and volunteers. Activities that attracted most participation were fun runs and health expos. Most used their understanding of community needs when deciding on activities. Only a small number relied on formal health needs analyses. Groups varied in their assessment of how well the activities they organised actually met needs. Half the group members had not worked together previously. All but 3 intend to work with others in the future. Most group members learnt more about health programs and other professionals in their community.

Implications
Raised profile of health services and role of health professionals and volunteers in rural Tasmania.
Increased range of ongoing health promoting activities. Better planned and coordinated activities.

The holy grail : the search for the optimal gaar

The sustainability of a taxation system relies in part in reducing effective tax avoidance as far as is possible. Tax avoidance impacts on the economy both because it results in revenue loss and because it diverts people into devising, marketing and implementing avoidance arrangements, rather than engaging in economically productive activities. Revenue losses in turn weaken the government's ability to formulate and implement fiscal policies. Moreover, the very integrity of a tax system, necessary for its long-term sustainability, is attacked by tax avoidance. The goal of equity is undermined by tax avoidance as typically these schemes are accessed by the wealthy. Thus, tax avoidance results in an unfair shift in the tax burden to the less wealthy in society. As one commentator recently noted, combating 'tax avoidance ... will serve to lessen the overall burden on all taxpayers'. Further, legislative responses to tax avoidance increase the complexity of a taxation scheme. Tax avoidance schemes also undermine the neutrality of a taxation system by distorting trade and investment decisions. Thus, tax avoidance attacks every aspect of a fair, and hence, sustainable, taxation system.

In search of the tendon holy grail : predictable clinical outcomes

What is your first reaction when you find out your next patient has a long-term tendinopathy? I suspect you want to hide or get an urgent phone call that drags you away from the practice. You know that the person will have tried multiple interventions, probably had several injections, read all the literature about treatments for tendinopathy on the internet and want an immediate and lifelong cure. You also know that your assessment will take well into your next patient’s time allotment and even then it will remain difficult to prioritise treatments and to explain the rationale behind your plan to the patient. Even as a tendon researcher and part-time clinician whose practice consists solely of tendinopathy patients, my reactions to chronic tendinopathy patients are similar.

'We learnt that last week' : reading into the language practices of teachers

The messages teachers convey to their students through their use of language can often go unconsidered, yet such practices can have a significant impact on students and their schooling, and in the creation of learning difficulties. In this paper we employ a discursive and ideological approach to analysing teachers’ language practices and suggest that such systematic examination is warranted given the centrality of ‘teacher talk’ to students’ schooling. We draw attention to these concerns through an analysis of a spoken text between a teacher and student in the context of ‘show and tell’; a dialogue drawn from a larger body of data of interviews with and observations of teachers in six Australian primary schools. The analysis attempts to uncover the meanings conveyed to the student in question, Sam, through his teacher’s language practices and to demonstrate the potentially detrimental effects of these practices on his schooling. Generally, we propose that teachers frequently employ linguistic techniques to refashion students in various ways, according to the norms of schooling; norms that often do not account very well for student difference and which position them as ‘difficult’. Specifically, we argue that Sam’s teacher seems more interested in moulding Sam’s behaviour to conform to the interests of the school than in valuing his heritage and contributions.
