Previous research suggests that meditation, a mindfulness exercise, could result in increased connectedness to nature and pro-environmental behavior. Exposure to nature also is associated with these outcomes. It was hypothesized that meditation alongside stimuli reminiscent of the natural environment would produce enhanced effects. Participants ( N = 97) were randomly assigned to complete a 4-week online meditation program consisting of a guided meditation paired with either nature sounds (“nature group”) or spa-like sounds (“control group”). Mindfulness, connectedness to nature, and pro-environmental behavior were assessed before and after the program. Meditation, in general, produced increases in mindfulness, connectedness to nature, and pro-environmental behavior. Additionally, the nature group had a greater rate of change in connectedness to nature when compared to the control group. The results extend previous cross-sectional research by demonstrating the beneficial effects of meditation on pro-environmental behavior and its theorized mechanisms, which may be informative for future research and interventions.

AbstractSince many linguistic structures are variable (i. e. conveyed by multiple forms), building a second-language grammar critically involves developing sociolinguistic competence (Canale and Swain. 1980. Theoretical bases of communicative approaches to second language teaching and testing. Applied Linguistics 1(1). 1–47), including knowledge of contexts in which to use one form over another (Bayley and Langman. 2004. Variation in the group and the individual: Evidence from second language acquisition. International Review of Applied Linguistics in Language Teaching 42(4). 303–318). Consequently, researchers interested in such competence have increasingly analyzed the study-abroad context to gauge learners’ ability to approximate local norms following a stay abroad, due to the quality and quantity of input to which learners may gain access (Lafford. 2006. The effects of study abroad vs. classroom contexts on Spanish SLA: Old assumptions, new insights and future research directions. In Carol Klee & Timothy Face (eds.), Selected proceedings of the 7th conference on the acquisition of Spanish and Portuguese as first and second languages, 1–25. Somerville, MA: Cascadilla Proceedings Project). Nevertheless, the present study is the first to examine native or learner variation between imperative (e. g. ven ‘come’) and optative Spanish commands (e. g. que vengas ‘come’). We first performed a corpus analysis to determine the linguistic factors to manipulate in a contextualized task, which elicited commands from learners before and after four weeks abroad in Alcalá de Henares, Spain. Their overall rates of selection and predictive factors were compared to local native speakers (NSs) and a control group of at-home learners.Results revealed that the abroad learners more closely approached NS rates of selection following the stay abroad. Nonetheless, for both learner groups conditioning by independent variables only partially approximated the NS system, which was more complex than previously suggested.

ABSTRACT Introduction: Worldwide cocaine use in all its various forms is increasing; cocaine users exceeded 17 million in the world. In Brazil, this data is also alarming. A survey conducted in 2010 found that the country has more than 900,000 crack-cocaine users. Objective: To evaluate the effects of exercise on anthropometric variables and components of physical fitness in ex-crack cocaine users. Methods: Randomized controlled trial with 20 men, divided into exercise group (n=10) and control group (n=10), admitted to a detoxification center. We assessed the physical fitness components related to health (cardiorespiratory endurance, flexibility, muscular strength/endurance, and body composition) before and after the physical training program. Results: The exercise contributed to the maintenance of anthropometric variables, while the control group had an increased in total body fat and visceral fat. Regarding physical fitness, resistance training led to the increase of most variables studied, particularly strength and cardiorespiratory capacity. On the other hand, the VO2max and the strength of the sedentary subjects were reduced (P<0.05). Conclusion: The exercise showed beneficial effects on the components of physical fitness and maintenance of body composition.

Abstract BackgroundThe purpose of this study was to investigate the effect of 12 months of aerobic exercise combining stachys lavandulifolia (S. lavandulifolia) consumption on anxiety, Metabolic Syndrome profiles and antioxidant defense (Glutathione) and lipid peroxidation (Malondialdehyde) in 50-65 years old women with syndrome metabolic.Methods48 women with syndrome Metabolic were randomly divided into four groups: exercise (n=12), exercise+S. lavandulifolia (n=12), S. lavandulifolia (n=12) and control group (n=12). S. lavandulifolia groups consumed 3 g aerial parts of S. lavandulifolia daily. Training groups performed an exercise protocol of aerobic exercise for 12 months (three sessions per week). Blood samples were obtained before and after training period for antioxidant indicators and lipid degradation measurement. Also, Beck anxiety questionnaire used for evaluating levels of anxiety. T-test and one-way analysis of variance were used for the evaluation of within-group and between-group differences, respectively.ResultsA significant increase was observed in serum levels of Malondialdehyde (P =0.004), Catalase indexes (Pvalue= 0.01), and Glutathione (P=0.001) in the training group and S. lavandulifolia groups after 12 months. Body weight, BMI, and SBP and Anexiety was decreased significantly greater in exercise +S. lavandulifolia group compared to control, exercise and S. lavandulifolia groups (P=0.001)ConclusionAnxiolytic effect and Anti-Oxidative Stress Activity was seen, so taking S. lavandulifolia along with exercises may have beneficial effects on reinforcement the antioxidant system and prevention of anxiety and The negative effects of indicators related to cardiovascular disease in women with metabolic syndrome.

ObjectivesAlterations in dopamine neurotransmission underlie some of the clinical features of Huntington’s disease (HD) and as such are a target for therapeutic intervention, especially for the treatment of chorea and some behavioural problems. However, justification for such an intervention is mainly based on case reports and small open label studies and the effects these drugs have on cognition in HD remain unclear.MethodsIn this study, we used the Enroll-HD observational database to assess the effects of antidopaminergic medication on motor, psychiatric and cognitive decline, over a 3-year period. We first looked at the annual rate of decline of a group of HD patients taking antidopaminergic medication (n=466) compared with an untreated matched group (n=466). The groups were matched on specified clinical variables using propensity score matching. Next, we studied a separate group of HD patients who were prescribed such medications part way through the study (n=90) and compared their rate of change before and after the drugs were introduced and compared this to a matched control group.ResultsWe found that HD patients taking antidopaminergic medication had a slower progression in chorea and irritability compared with those not taking such medications. However, this same group of patients also displayed significantly greater rate of decline in a range of cognitive tasks.ConclusionIn conclusion we found that antidopaminergic treatment is associated with improvements in the choreic movements and irritability of HD but worsens cognition. However, further research is required to prospectively investigate this and whether these are causally linked, ideally in a double-blind placebo-controlled trial.

There is substantial interest in identifying the behavioral means by which to improve cognitive performance. Recent research and commercial ventures have focused on cognitive training interventions, but evidence suggests that the effects of these programs are small and task-specific. Researchers have also shown interest in exploring the potential benefits of physical activity for cognitive performance. Because the effects of physical activity have been found to be small to moderate and to be more global in nature, interest in physical activity has been growing over the past several decades. Evidence regarding the efficacy of physical activity is provided through cross-sectional studies, longitudinal prospective studies, and randomized controlled trials. When reviewed meta-analytically, small-to-moderate beneficial effects are reported for children, adults, older adults, and cognitively impaired older adults, and these effects are evident for a wide range of cognitive domains, including executive function, memory, and information processing. Researchers are currently focused on identifying the mechanisms of these effects. Most of this research has been conducted using animal models, but there is a growing body of literature with humans. From this evidence, there is support for the role of changes in cerebral structure, hippocampal perfusion, and growth factors in explaining the observed benefits. Thus far, however, the literature is quite sparse, and future research is needed to clarify our understanding of the mechanisms that provide the causal link between physical activity and cognitive performance. Research is also focused on understanding how to increase the benefits by potentially combining cognitive training with physical activity and by identifying the genetic moderators of the effects. These lines of work are designed to elucidate ways of increasing the magnitude of the benefits that can be obtained. At this point in time, the evidence with respect to the potential of physical activity for benefiting cognitive performance is quite promising, but it is critical that funding agencies commit their support to the continued exploration necessary to allow us to ultimately be able to prescribe physical activity to specific individuals with the express purpose of improving cognition.

In this article, we reviewed results of research on near-death experiences (NDEs) over the past 3 decades and examined the effect of viewing the hour-long 2002 BBC documentary The Day I Died: The Mind, the Brain, and Near-Death Experiences on accurate knowledge about near-death experiences among advanced undergraduates at a southwestern university. In a quasi-experimental research design, the experimental group completed a 20-item questionnaire before and after viewing the documentary ( n = 66; 45 females, 21 males), and the waitlist control group completed the questionnaire as pre- and posttest before viewing the documentary ( n = 39; 36 female, 3 male). The two groups' scores at pretest were not significantly different ( p > .05). Group by occasion repeated measures ANOVA revealed the experimental group's posttest scores moved significantly in the direction of correctness with a large effect size ( p < .001; η2= .56), whereas waitlist control group posttest scores remained similar to pretest scores. We discuss two exceptions to the effectiveness of the documentary and recommendations for educators using it as well as for future research.

9549 Background: The impact of BC on HRQL is poorly understood. To our knowledge, this is the first and largest cross-sectional study that compares HRQL of patients before and after BC diagnosis (DX). Methods: Our sample included 1,476 BC patients (≥ age 65) within the SEER-Medicare Health Outcomes Survey linkage database (1998-2007). We assessed differences in HRQL as measured by SF-36 physical (PCS) and mental (MCS) summary scores in patients who had a survey >1 yr before BC DX (n=620) and those who had a survey after BC DX (n=856). We compared groups by year from BC DX using regression analyses and results were adjusted for cancer stage, race, gender, age at BC DX, marital status, education, income, smoking status, activity of daily living (ADLs), and non-cancer comorbidities. Results: Patients who had a survey after BC DX were diagnosed with BC at an older age than those with a survey before BC DX (55.9% at age ≥75 yr vs. 36.8%; P<0.01). Other baseline demographic and socioeconomic characteristics were similar. Baseline HRQL were poor in patients before DX (PCS mean=40.1; MCS mean=51.1) with 50.6% and 31.9% of them having comorbidity score ≥2 and impairment of ≥1 ADLs, respectively. After BC DX, significant decreases in PCS (-2.7; 95% CI -3.8,-1.7) and MCS (-1.4; 95% CI -2.6, -0.3) were observed, with HRQL being lowest in those who had BC DX within 1 yr (PCS mean= 36.6; MCS mean=49.7). Declines in PCS during the <1, 1-3, 3-5, 5-10, and 10+ yr periods after BC DX compared to before BC DX were -3.8 (P<0.01), -2.5 (P<0.01), -2.2 (P=0.01), -1.1 (P=0.19) and -0.8 (P=0.57) whereas decreases in MCS were -2.0 (P=0.01), -2.2 (P<0.01), -1.2 (P=0.21), -0.1 (P=0.92), -0.8 (P=0.62) respectively. More advanced BC, lower educational level, higher comorbidity score, and impaired ADLs were significantly associated with both worse PCS and MCS after BC DX (P<0.05). Lower income and older age at BC DX showed significant association with low PCS (P<0.05). Conclusions: Older BC patients are a vulnerable population with poor baseline HRQL. HRQL of patients after BC DX is significantly worse than HRQL of patients before DX, possibly due to therapy and/or disease progression. Future research that evaluates interventions to improve HRQL in older patients with BC is critical.

ABSTRACTPast studies of aging and disability have been restricted to and by cross-sectional data. When cross-sectional surveys measure income, disability status and age at a common point in time, it is impossible to discern the process, and consequences, of a disability onset. In other words, it is not possible to examine the circumstances of the same individuals before, and after, the disability onset; nor whether effects differ according to the age at which the disability occurs. The present study uses a new panel data set, the Survey of Labour and Income Dynamics (SLID), to examine the prevalence of disability with respect to age, gender, and other socio-economic characteristics; however, its unique contribution is its investigation of disability onset, and the rates of entry into, and exit from, disability status by age group and gender. Further, we assess the financial circumstances of those who become disabled vis-à-vis a “control group”.

Dose Dependent Decrease

Endothelin (ET) may have both detrimental (reduced coronary flow) and beneficial effects (positive inotrope, reduced arrhythmogenesis) following ischaemia. We examined the effects of ET on cardiac function during reperfusion following prolonged hypothermic cardioplegic arrest in a protocol mimicking cardiac transplantation. Isolated working rat hearts were perfused with Krebs buffer to which increasing concentrations of ET-1 or sarafotoxin S6c had been added. Identical experiments were performed after 4h of cardioplegic arrest at 4°C. Under pre-ischaemic conditions ET-1 caused a dose-dependent decrease in cardiac function compared with controls. In contrast, following ischaemia low doses of ET-1 (10-10 M) caused a significant and beneficial increase in cardiac output (109.1% versus 81.3%), dP/dt i.e. the rate of change of pressure with time (94.7% versus 75.6%) and stroke volume (100.3% versus 77.5%) compared with controls (P<0.05). At higher doses of ET-1 there was a detrimental effect on cardiac output, dP/dt and stroke volume similar to that seen prior to ischaemia. Sarafotoxin S6c had no significant effect pre or post ischaemia on any of the parameters measured compared with controls (P = not significant). ET-1 at low concentrations during reperfusion can improve the recovery of cardiac function mediated via ETA receptors. ET may play an important physiological role in the recovery of cardiac function following prolonged ischaemia.

The purpose of this study was to examine the influence of an interactive, educational workshop on hazing knowledge, intentions to haze and intentions to prevent hazing. Components of the workshop included discussion on hazing definitions, prevalence, causes, consequences, and prevention. Nineteen sport club officers at a midsize university served as the intervention group and a convenience sample of 44 sport club student-athletes served as a control group. Hazing knowledge increased among workshop attendees and workshop attendees had greater hazing knowledge before and after the intervention in comparison with the control group who received no intervention. However, intentions to haze and the intentions to prevent hazing did not differ among groups. The intervention group increased their knowledge of where to report hazing acts and attitudes toward alternative activities to hazing. Recommendations for future research and hazing interventions for administrators are provided.
