Architectural Glass & Cladding has put their reputation behind the trusted and innovative products of Okalux GmbH. -- Architectural Glass & Cladding has put their reputation behind the trusted and innovative products of Okalux GmbH. Since 2010, their close partnership has helped the architectural community to discover the advantages of energy efficiency, end user comfort and the use of natural daylight to reduce the running costs of buildings throughout Australia and South East Asia."Our goal is to develop optimum solutions to satisfy architects specific demands – with glass," said Paul Nipperess, Sales and Marketing Manager of Architectural Glass & Cladding. AG&C has more than 20 years experience in the glass and façade industries."Okalux has decades of experience in the development and manufacture of high quality insulating glass for international construction projects. The very first product which sparked off the idea for the founding of the company also set the standard for its powers of innovation. Hollow fibres, which were originally conceived for the textiles industry, produce great advantages when inserted in the space between the panes of a window: they produce a soft diffusion of daylight and deep illumination of interiors," said Paul.This was followed by systems for light deflection and improved diffusion, transparent heat insulation and energy reduction. Paul goes on to say, "Glass is one of the most fascinating materials available to architects. It allows natural light into buildings and contributes decisively towards the end user's comfort. Okalux has dedicated itself to using natural light and ensuring that its products produce a balance of often contradictory demands; supplying a building with light and thermal energy while simultaneously protecting against overheating, heat loss and UV radiation." Because of this, Paul has called on architects, designers and builders to keep windows on their radar early by "creating purpose built solutions."This partnership between Okalux and Architectural Glass and Cladding has provided solutions to many key projects by utilising many of the unique and innovative Okalux products. These projects include: 570 Bourke Street Melbourne, Australian Catholic University NSW, Australian War Memorial ACT, The Peter Doherty Institute (University of Melbourne), Illumin8 Building (Adelaide University), Malaiwana Estate (Phuket Thailand), and 5 Martin Place (Sydney). Projects currently under construction include Monash University (Melbourne), and the Hong Kong Art Museum.For more information contact Architectural Glass & Cladding Pty Ltd, Suite 17, Wharf Central, 75 Wharf Street, Tweed Heads NSW 2485, phone 07 5523 2335, fax 07 5523 2336, email: info@agcproducts.com.au ( mailto://info@ agcproducts.com.au ), website: http://www.agcproducts.com.au

Brain region-specific changes have been demonstrated with a variety of cognitive training interventions. The effect of cognitive training on brain subnetworks in humans, however, remains largely unknown, with studies limited to functional networks. Here, we used a well-established working memory training program and state-of-the art neuroimaging methods in 40 healthy adults (21 females, mean age 26.5 years). Near and far-transfer training effects were assessed using computerized working memory and executive function tasks. Adaptive working memory training led to improvement on (non)trained working memory tasks and generalization to tasks of reasoning and inhibition. Graph theoretical analysis of the structural (white matter) network connectivity (“connectome”) revealed increased global integration within a frontoparietal attention network following adaptive working memory training compared with the nonadaptive group. Furthermore, the impact on the outcome of graph theoretical analyses of different white matter metrics to infer “connection strength” was evaluated. Increased efficiency of the frontoparietal network was best captured when using connection strengths derived fromMRmetrics that are thought to be more sensitive to differences in myelination (putatively indexed by the [quantitative] longitudinal relaxation rate, R1) than previously used diffusion MRI metrics (fractional anisotropy or fiber-tracking recovered streamlines). Our findings emphasize the critical role of specific microstructural markers in providing important hints toward the mechanisms underpinning training-induced plasticity that may drive working memory improvement in clinical populations. © 2016 the authors.

Novel activities and experiences shape the brain's structure and organisation and, hence, our behaviour. However, evidence from structural plasticity studies remains mixed and the neural correlates of learning and practice are still poorly understood. We conducted a robustly designed study into grey matter plasticity following 2 months of working memory training. We generated a priori hypotheses regarding the location of plastic effects across three cognitive control networks (executive, anterior salience and basal ganglia networks), and compared the effects of adaptive training (n = 20) with a well-matched active control group (n = 20) which differed in training complexity and included extensive cognitive assessment before and after the training. Adaptive training relative to control activities resulted in a complex pattern of subtle and localised structural changes: Training was associated with increases in cortical thickness in right-lateralised executive regions, notably the right caudal middle frontal cortex, as well as increases in the volume of the left pallidum. In addition the training group showed reductions of thickness in the right insula, which were correlated with training-induced improvements in backward digit span performance. Unexpectedly, control activities were associated with reductions in thickness in the right pars triangularis. These results suggest that the direction of activity-induced plastic changes depend on the level of training complexity as well as brain location. These observations are consistent with the view that the brain responds dynamically to environmental demands by focusing resources on task relevant networks and eliminating irrelevant processing for the purpose of energy reduction. © 2016 The Authors.

The Quality in Acute Stroke Care (QASC) was a cluster randomised control trial (CRCT) which evaluated the effectiveness of evidence-based clinical treatment protocols for the management of fever, hyperglycaemia and swallowing, in conjunction with multidisciplinary team building workshops, and a standardised interactive staff education program (collectively known as the Fever, Sugar, Swallowing (FeSS) intervention) to improve patient outcomes 90-days. We found that patients cared for in stroke units who received our intervention were 15·7% more likely to be alive and independent 90 days following their stroke. They also had significantly: fewer episodes of fever, lower mean temperatures, lower mean blood glucose levels, and better screening for swallowing difficulties. © 2012 The Author.

Exercise represents a major challenge to whole-body homeostasis provoking widespread perturbations in numerous cells, tissues, and organs that are caused by or are a response to the increased metabolic activity of contracting skeletal muscles. To meet this challenge, multiple integrated and often redundant responses operate to blunt the homeostatic threats generated by exercise-induced increases in muscle energy and oxygen demand. The application of molecular techniques to exercise biology has provided greater understanding of the multiplicity and complexity of cellular networks involved in exercise responses, and recent discoveries offer perspectives on the mechanisms by which muscle "communicates" with other organs and mediates the beneficial effects of exercise on health and performance. ©2014 Elsevier Inc.

Benefits of community-based whole-body vibration (WBV) as a mode of exercise training for people with chronic obstructive pulmonary disease (COPD) have not been investigated. The low skill demand of WBV may enhance habitual sustainability to physical activity by people with COPD, provided efficacy of WBV can be established. The purpose of this trial was to compare a community-based WBV intervention with a sham WBV (SWBV) intervention and monitor exacerbations, exercise tolerance, and functional performance of the lower limbs of people with COPD. Community-dwelling adults with a GOLD clinical diagnosis of COPD were recruited to the trial. This was a Phase II efficacy trial with crossover to sham intervention interspersed with two-week washout. Each six-week intervention consisted of two sessions per week of either WBV or SWBV. The interventions were completed in the home of each participant under supervision. The outcome measures were selected psychological (perceived dyspnoea) and physiological (heart rate and oxygen saturation) responses to exercise, simulated activities of daily living (timed-up-and got test and 5-chair stands test), and selected kinematic variables of gait across the 14-week trial. Sixteen adults with stable COPD were recruited to the trial. No exacerbations were reported during the WBV or SWBV interventions. After WBV, performance of activities of daily living (ADLs) and gait improved (p ≤ 0.05), while there was no change after SWBV (p > 0.05). Despite five withdrawals during the washout period, a 100% compliance to each six-week intervention was noted. Results showed that WBV did not exacerbate symptoms of COPD that can be associated with physical inactivity. The WBV intervention improved tests to simulate ADLs such as rising from a chair, turning, and walking gait with greater effect than a SWBV intervention. If a placebo effect was systemic to the WBV intervention, the effect was negligible. As a standalone community-based intervention, WBV was an efficacious mode of exercise training for people with stable COPD that did not negatively effect exercise tolerance or exacerbate the disease, while concurrently improving functional performance of the lower limbs.

Purpose: A limitation of most rugby league time-motion studies is that researchers have examined the demands of single teams, with no investigations of all teams in an entire competition. This study investigated the activity profiles and technical and tactical performances of successful and less-successful teams throughout an entire rugby league competition. Methods: In total, 185 rugby league players representing 11 teams from a semiprofessional competition participated in this study. Global positioning system analysis was completed across the entire season. Video footage from individual matches was also coded via notational analysis for technical and tactical performance of teams. Results: Trivial to small differences were found among Top 4, Middle 4, and Bottom 4 teams for absolute and relative total distances covered and distances covered at low speeds. Small, nonsignificant differences (P =.054, ES = 0.31) were found between groups for the distance covered sprinting, with Top 4 teams covering greater sprinting distances than Bottom 4 teams. Top 4 teams made more meters in attack and conceded fewer meters in defense than Bottom 4 teams. Bottom 4 teams had a greater percentage of slow play-the-balls in defense than Top 4 teams (74.8% ± 7.3% vs 67.2% ± 8.3%). Middle 4 teams showed the greatest reduction in high-speed running from the first to the second half (-20.4%), while Bottom 4 teams completed 14.3% more high-speed running in the second half than in the first half. Conclusion: These findings demonstrate that a combination of activity profiles and technical and tactical performance are associated with playing success in semiprofessional rugby league players. © 2014 Human Kinetics, Inc.

The aim of this study was to determine if simulation aided by media technology contributes towards an increase in knowledge, empathy, and a change in attitudes in regards to auditory hallucinations for nursing students. A convenience sample of 60 second-year undergraduate nursing students from an Australian university was invited to be part of the study. A pre-post-test design was used, with data analysed using a paired samples t-test to identify pre- and post-changes on nursing students' scores on knowledge of auditory hallucinations. Nine of the 11 questions reported statistically-significant results. The remaining two questions highlighted knowledge embedded within the curriculum, with therapeutic communication being the core work of mental health nursing. The implications for practice are that simulation aided by media technology increases the knowledge of students in regards to auditory hallucinations. © 2013 Australian College of Mental Health Nurses Inc.

Purpose: No study has investigated the frequency and nature of repeated high-intensity-effort (RHIE) bouts across elite and semielite rugby league competitions. This study examined RHIE activity in rugby league match play across playing standards. Participants: 36 elite and 64 semielite rugby league players. Methods: Global positioning system analysis was completed during 17 elite and 14 semielite matches. Results: The most commonly occurring RHIE bouts involved 2 efforts (2-RHIE) for both elite and semielite players. Only small differences were found in 2-RHIE activity between elite and semielite match play (effect size [ES] ≥0.31 ± 0.15, ≥88%, likely). RHIE bouts were more likely to involve contact as the number of efforts in a bout increased (ES ≥0.40 ± 0.15, 100%, almost certainly). Semielite players performed a greater proportion of 2-contact-effort RHIE bouts than their elite counterparts (68.2% vs 60.6%, ES 0.33 ± 0.15, 92%, likely), while elite players performed a greater proportion of 3-effort bouts (26.9% vs 21.1%, ES 0.31 ± 0.15, 88%, likely). Elite players also had a shorter recovery (1.00-3.99 vs ≥4.00 min) between RHIE bouts (ES ≥1.60 ± 0.71, ≥94%, likely). Conclusion: These findings highlight the RHIE demands of elite and semielite rugby league match play. Elite players are more likely to perform RHIE bouts consisting of 3 efforts and to have a shorter recovery time between bouts. Exposing players to these RHIE demands in training is likely to improve their ability to tolerate the most demanding passages of match play. © 2015 Human Kinetics, Inc.

Herbal medicine interventions have been identified as having potential benefit in the treatment of rheumatoid arthritis (RA). To update an existing systematic (Cochrane) review of herbal therapies in RA. We searched electronic databases Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, AMED, CINAHL, Web of Science, Dissertation Abstracts (1996 to 2009), unrestricted by language, and the WHO International Clinical Trials Registry Platform in October 2010. Randomised controlled trials of herbal interventions compared with placebo or active controls in RA. Two authors selected trials for inclusion, assessed risk of bias and extracted data.  Twelve new studies were added to the update, a total of 22 studies were included.Evidence from seven studies indicate potential benefits of gamma linolenic acid (GLA) from evening primrose oil, borage seed oil, or blackcurrent seed oil, in terms of reduced pain intensity (mean difference (MD) -32.83 points, 95% confidence interval (CI) -56.25 to -9.42,100 point pain scale); improved disability (MD -15.75% 95% CI -27.06 to -4.44%); and an increase in adverse events (GLA 20% versus placebo 3%), that was not statistically different (relative risk 4.24, 95% CI 0.78 to 22.99).Three studies compared Tripterygium wilfordii (thunder god vine) to placebo and one to sulfasalazine and indicated improvements in some outcomes, but data could not be pooled due to differing interventions, comparisons and outcomes. One study reported serious side effects with oral Tripterygium wilfordii Hook F. In the follow-up studies, all side effects were mild to moderate and resolved after the intervention ceased. Two studies compared Phytodolor(®) N to placebo but poor reporting limited data extraction. The remaining studies each considered differing herbal interventions. Several herbal interventions are inadequately justified by single studies or non-comparable studies in the treatment of rheumatoid arthritis. There is moderate evidence that oils containing GLA (evening primrose, borage, or blackcurrant seed oil) afford some benefit in relieving symptoms for RA, while evidence for Phytodolor® N is less convincing.Tripterygium wilfordii products may reduce some RA symptoms, however, oral use may be associated with several side effects. Many trials of herbal therapies are hampered by research design flaws and inadequate reporting. Further investigation of each herbal therapy is warranted, particularly via well designed, fully powered, confirmatory clinical trials that use American College of Rheumatology improvement criteria to measure outcomes and report results according to CONSORT guidelines.
