Market models of education reform predict that the growth of charter schools will infuse competition into the public school sector, forcing traditional public schools to improve the practices they engage in to educate students. Some scholars have criticized these models, arguing that competition from charter schools is unlikely to produce…

Full Text Available In traditional teaching most of the class time is spent with the professor lecturing and the students watching and listening. The students work individually, and cooperation is discouraged. On the other hand, active learning changes the focus of activity from the teacher to the learners, in which students solve problems, answer questions, formulate questions of their own, discuss, explain, debate during class; moreover, students work in teams on problems and projects under conditions that assure positive interdependence and individual accountability. Although student-centered methods have repeatedly been shown to be superior to the traditional teacher-centered approach to instruction, the literature regarding the efficacy of various teaching methods is inconclusive. The purpose of this study was to compare the student perceptions of course and instructor effectiveness, course difficulty, and amount learned between the active learning and lecture sections in Health Sciences´ courses by statistical data from Anhembi Morumbi University. Results indicated significant difference between active learning and traditional teaching. Our conclusions were that strategies promoting active learning to traditional lectures could increase knowledge and understanding.
Full Text Available One of the most contentious urban education policy issues in the United States today is the expansion of charter schools and its repercussions. Does the expansion of charter schools affect the racial and socioeconomic composition of traditional public schools in the United States? This study provides empirical evidence on this question by relying on a panel design that uses school-level data from two states that have experimented with charter schools for more than 15 years: Ohio and Texas. Using county-level, spatial, and enrollment-based measures of charter exposure, the changes from pre- to post-charter-legislation stages in the student compositions of public schools that do and do not face competition from charters are examined. The results suggest that charter school presence contributes to aggregate-level changes in the share of non-Hispanic White and free-lunch-eligible students in traditional public schools in both states in different ways.

To examine the prevalence of traditional and Internet bullying and the personal, family, and school environment characteristics of perpetrators and victims. Students (12-14 years old) in 35 junior high schools were randomly selected from the Jerusalem Hebrew (secular and religious) and Arab educational system (n = 2,610). Students answered an anonymous questionnaire, addressing personal, family, and school characteristics. Traditional bullying and Internet bullying for perpetrators and victims were categorized as either occurring at least sometimes during the school year or not occurring. Twenty-eight percent and 8.9 % of students were perpetrators of traditional and Internet bullying, respectively. The respective proportions of victims were 44.9 and 14.4 %. Traditional bullies presented higher Odds Ratios (ORs) for boys, for students with poor social skills (those who had difficulty in making friends, were influenced by peers in their behavior, or were bored), and for those who had poor communication with their parents. Boys and girls were equally likely to be Internet bullies and to use the Internet for communication and making friends. The OR for Internet bullying victims to be Internet bullying perpetrators was 3.70 (95 % confidence interval 2.47-5.55). Victims of traditional bullying felt helpless, and victims of traditional and Internet bullying find school to be a frightening place. There was a higher OR of Internet victimization with reports of loneliness. Traditional bully perpetrators present distinctive characteristics, while Internet perpetrators do not. Victims of traditional and Internet bullying feel fear in school. Tailored interventions are needed to address both types of bullying.

In the United States, primary and secondary online schools are institutions that deliver online curricula for children enrolled in kindergarten through 12th grade (K-12). These institutions commonly provide opportunities for online instruction in conjunction with local schools for students who may need remediation, have advanced needs, encounter unqualified local instructors, or experience scheduling conflicts. Internet-based online schooling may potentially help children from populations known to have educational and health disadvantages, such as those from certain racial or ethnic backgrounds, those of low socioeconomic status, and children with special health care needs (CSHCN). To describe the basic and applied demographics of US online-school users and to compare student achievement in traditional versus online schooling environments. We performed a brief parental survey in three states examining basic demographics and educational history of the child and parents, the child's health status as measured by the CSHCN Screener, and their experiences and educational achievement with online schools and class(es). Results were compared with state public-school demographics and statistical analyses controlled for state-specific independence. We analyzed responses from 1971 parents with a response rate of 14.7% (1971/13,384). Parents of online-school participants were more likely to report having a bachelor's degree or higher than were parents of students statewide in traditional schools, and more of their children were white and female. Most notably, the prevalence of CSHCN was high (476/1971, 24.6%) in online schooling. Children who were male, black, or had special health care needs reported significantly lower grades in both traditional and online schools. However, when we controlled for age, gender, race, and parental education, parents of CSHCN or black children reported significantly lower grades in online than in traditional schooling (adjusted odds ratio [a
Community involvement in education has been viewed as a - by no means uncontroversial - means for enabling local members to deepen their participation in the decision-making relevant to their schools by playing a constructive role in the process. On the basis of a study carried out in Ghana, the present contribution to this discussion examines various matters involved in delegating the management of an Alternative Primary Education program to two traditional communities in the north of that country. It also explores how community members, school authorities, the sponsoring non-governmental organization and members of the local management committee themselves perceive such an approach to school management. Issues raised include whether inexperienced and even illiterate local citizens should be allowed to manage their schools, the conflicts which such management often entails and, finally, in what ways it might be beneficially promoted.

To determine the prevalence of xerophthalmia at a traditional boarding school where children do not receive a diet adequate in vitamin A. A cross-sectional survey of 406 males residing in a Quranic traditional school was conducted using the World Health Organization xerophthalmia checklist. The association between the prevalence of night blindness and proportion of students staying at the school for 6 consecutive months and those eating solely at the school was investigated. The difference in age between children with night blindness and those without was investigated. Statistical significance was indicated by P<0.05. The prevalence of night blindness, conjunctival xerosis and Bitot's spots was 24%, 12.5% and 1%, respectively. None of the boys had corneal ulceration, corneal scars and corneal xerosis. No significant association was observed between the differences in mean age and development of night blindness (P=0.657). There was a significant association between the duration of stay (cut-off of 6 months continuously) at the institute and the development of night blindness (P=0.023). There was no statistical significance between regularly eating at the maseed and outside the "maseed" and the development of night blindness (P=0.75). Children residing at a traditional school are vulnerable to developing xerophthalmia where the diet is inadequate in vitamin A. Institutional caregivers should be made aware of the importance of providing a balanced diet rich in vitamin A. Institutional caregivers should also be educated on the signs and symptoms of vitamin A deficiency for early detection of xerophthalmia.

Full Text Available Many games have been preserved as a custom, particularly among children, much after the young used to play them. In most of the cases, traditional games represent imitation of the adults’ society. Those games are numerous, with an easy start and ending, so the children use them in any possible situation. The implementation of these games and some traditional toys in the nurseries and primary schools in Novi Pazar, has proved our assumptions that teachers has given them positive marks, and even more important is that children are eager to use them and show some interests for their existence. A school can apply various sources within educational process and other out school activities.

Full Text Available The paper presents views of Adolphe Ferrière, a Swiss educator and psychologist and a Professor at the "Jean-Jacques Rousseau" Institute, about active school - one of the "new school" movements that emerged in the first half of 20th century as a countermove to traditional school founded on Herbartian conception of education. Condemning old school’s intellectualism and verbalism, active school turns towards a child, his nature, needs and interests, and declares activity, "child’s self-work", the basic principle of education. The paper points out Ferrière’s contributions to the transformation of "learning school" into "working and activity school". After presenting Ferrière’s criticism of traditional school as well as a number of "new school" movements, the author provides in more detail essential features of active school. Ferrière’s argumentation against attempts to identify active school with "handwork school" and against tendencies to make it equal with "active methods" is herein presented. Also, the author elaborates why Ferrière turns down the objection that active school neglects intellectual education and why he does not accept pragmatic qualifications of active school. Consideration is given to the demands of active school for teacher education i.e. characteristics that a "new school" teacher should possess as required by Ferrière.

Full Text Available This paper describes the botanical features of Ficus carica L. (Moraceae, its wide variety of chemical constituents, its use in traditional medicine as remedies for many health problems, and its biological activities. The plant has been used traditionally to treat various ailments such as gastric problems, inflammation, and cancer. Phytochemical studies on the leaves and fruits of the plant have shown that they are rich in phenolics, organic acids, and volatile compounds. However, there is little information on the phytochemicals present in the stem and root. Reports on the biological activities of the plant are mainly on its crude extracts which have been proven to possess many biological activities. Some of the most interesting therapeutic effects include anticancer, hepatoprotective, hypoglycemic, hypolipidemic, and antimicrobial activities. Thus, studies related to identification of the bioactive compounds and correlating them to their biological activities are very useful for further research to explore the potential of F. carica as a source of therapeutic agents.

Teachers' efficacy beliefs have been shown to correlate positively with to the successful implementation of science reform measures (National Research Council, 1996) and are context specific (Koul & Rubba, 1999). Studies on teacher efficacy in specific contexts have been conducted including the availability of resources and parent support (Tschannen-Moran & Hoy, 2002), classroom management (Emmer & Hickman, 1990; Raudenbush, Rowen, & Cheong, 1992); and institutional climate and behavior of the principal (Hoy & Woolfolk, 1993). The purpose of this study was to compare the science teaching efficacy beliefs of teacher interns prepared in professional development schools with those of student teachers prepared in traditional school settings. Other variables examined included academic level, academic major, and area of science concentration. Preservice science teacher efficacy beliefs were measured using the Science Teaching Efficacy Beliefs Instrument for Preservice Science Teachers, STEBI Form B (Enoch & Riggs, 1990) with demographic information being collected by an accompanying questionnaire. Analyses included scoring the surveys on two scales, Personal Science Teaching Efficacy Beliefs Scale and the Outcome Expectancy Scale, calculating descriptive statistics, as well as performing MANOVAS and correlations. Results indicate that preservice science teachers working in professional development schools exhibit higher personal science teaching efficacy beliefs. This finding corroborates previous studies on the efficacy beliefs of preservice teachers working in PDS schools (Long, 1996; Sandholtz & Dadlez, 2000). Results also show a strong correlation between the personal science teaching efficacy beliefs and the setting where student teaching takes place. In addition, significant differences were found in the personal science teaching efficacy beliefs between elementary education majors and science majors, science education majors, and secondary education majors

Full Text Available Physical Education teachers have been using some very classic team sports, like football, basketball, handball, volleyball, etc. for many years in order to develop their education work at school. As a consequence of this, the benefits of this kind of activities on Physical Education lessons have not been as notable as we mighthave expected, since, even if they are increasing, their development and application are still low. There are many and very varied new non-traditional sports that have emerged and extended across Spain in recent years. To mention an example, we could refer to a newly created non-traditional sport such as kin-ball. This sport wascreated for the purpose of achieving a way to combine several factors such as health, team-work and competitiveness. Three teams of four players each participate. This way, every player can participate to a great extent in all the moves of the match, for each of them must defend one area of their half in order to achieve a common objective. Besides, kin-ball helps to develop motor skills at school in an easy way; that is, coordination, balance and perception. There is a large variety of non-traditional games and sports that are similar to kin-ball, such as floorball, intercrosse, mazaball, tchoukball, ultimate, indiaca, shuttleball... All of them show many physical, psychic and social advantages, and can help us to make the Physical Education teaching-learning process more motivating, acquiring the recreational component that it showed some years ago and which hasnow disappeared

Our aims in this study were to identify the types of physical activity during leisure time and to determine if Korean secondary school girls participate in enough physical activity during leisure time to promote health. Of the 1,088 girls randomly selected by a multistaged cluster sampling technique, 705 girls completed questionnaires. Seventy-five percent of Korean secondary school girls spent time on individualized or noncompetitive activities, and 88.3% of them were classified into underactive and inactive levels with no gained health benefits during leisure time. No significant differences were observed in the physical activity levels between middle school girls and high school girls. The results of this study may be explained by the lack of perceived appropriateness for secondary school girls' participation in physical activity, which traditionally did not favor them participating in dynamic physical activities and sufficient physical activity level to gain health benefits.

Archaeology can fill the gap between ancient population and modern society elucidating the evidences found in archaeological sites. The fingerprint identified, that is the chemical composition of the ceramics, can help understanding this connection between the past and the present. The Tupiguarani Tradition vestiges found by archaeologists will be a way to know about the last two millennia of the Brazilian prehistory. This archaeological site is located along the coast of the Brazilian State of Espirito Santo, where the main evidence is a pretty ceramic with the occurrence of plastic and painted decoration. When the Portuguese settlers arrived in this region, in sixteenth century, several Missoes Jesuiticas (Jesuitical Missions) were built along the Brazilian coast. In spite of living within the Mission and been catechized, the Indians kept on producing traditional handicraft, as the decorated ceramic, however, they introduced European elements to the decoration. During the research expeditions made to the archaeological site of the Tupiguarani Tradition, many sherds were found. The identification and classification of ceramics through a multielemental chemistry analysis will be used to determine if they have the same origin. This paper shows the first elemental concentration results of the sherds collected from archaeological site determined at CDTN/CNEN, Belo Horizonte, Minas Gerais, using the TRIGA Mark I IPR-R1 nuclear reactor, applying the neutron activation technique, k 0 -method.

Nature is a rich source of taste-active compounds, in particular of plant origin, many of which have unusual tastes. Many of these are found in traditional food, where spontaneous plants are used as ingredients. Some taste-active compounds were identified in the bulbs of Muscari comosum, a spontaneous plant belonging to the family of the Liliaceae, very common in the Mediterranean area, and used in traditional gastronomy (called 'lampascioni' in South Italy). The bulbs were extracted with a series of solvents of different polarity. The different fractions were submitted to a preliminary sensory evaluation, and the most interesting ones, characterized by a strong bitter taste and some chemestetic properties, were submitted to further purification and structural analysis. From the ethereal extract, several 3-benzyl-4-chromanones and one stilbene derivative were isolated. Pure compounds were examined for their taste activity by means of sensory evaluation, and proved to be responsible for the characteristic taste of this food. Some of these compounds have been synthesized de novo to confirm their structure.

This study explored stress predictors and the role of instructional methods and institutional differences in perceived stress levels amongst students at two Asian dental schools. An anonymous questionnaire was distributed to undergraduate dental students at Tokyo Medical and Dental University (TMDU), Japan and the University of Medicine and Pharmacy (UMP), Hochiminh City, Vietnam in 2016. Data concerning the students' demographic information and grades, and responses to the Perceived Stress Scale (PSS) and Dental Environment Stress questionnaire (DES) were collected. The questionnaires were prepared in English and translated into Japanese and Vietnamese following a forward-backward translation process. Altogether 684 students answered the questionnaire with a response rate of 97% for TMDU and 89% for UMP. The mean DES score of UMP students was significantly higher than TMDU (P stress scores in several areas than UMP preclinical students. Having dentistry as their first choice of educational programme was a significant stress predictor for Japanese students whilst the clinical practicum was a significant stress predictor for Vietnamese students. Previous academic performance was not a significant stress predictor for students at either dental school. Dental students of an integrated, active-learning curriculum reported lower stress levels than students of a traditional, discipline-based curriculum. © 2018 John Wiley & Sons A/S.

Full Text Available This study (1 reports frequency rates of mutually exclusive traditional, cyber and combined (both traditional and cyber bullying roles; and (2 investigates whether adolescents belonging to particular bullying roles show higher levels of involvement in risky online activities (Compulsive Internet Use (CIU, online grooming victimization, and sexting and risky offline activities (bad behavior in school, drinking alcohol and truancy than non-involved adolescents. The sample comprised self-reports of 1928 German, Dutch and Thai adolescents (Age = 12–18; M = 14.52; SD = 1.6. The results revealed age, sex and country differences in bullying frequency rates. CIU, sending of sexts and risky offline activities were most strongly associated with combined bully-victims. The receiving of sexts was most strongly associated with combined bullies; and online grooming victimization was most strongly related to cyber bully-victims. Another important finding is that the associations between risky offline activities and combined bullying are stronger than for traditional and cyber bullying. The findings contribute to better understanding of the associations between varying bullying roles and risky online and offline activities among adolescents. In sum, the results underscore the need to promote life skills rather than adopting more conventional approaches, which focus almost exclusively on reduction of risks.

The pressing need for educated nursing staff in Greece was first recognized by Queen Olga and Crown Princess Sofia, at the end of the nineteenth century with significant international aid.As a result, the School of Nursing Sisters of the Sanatorium "Evangelismos" was founded in 1875 and the first Greek "School of Certified Nurses" of the "Saint Sophia" Children's Hospital was established in 1897. This Children's Hospital has provided Greece with excellent trained nurses in Pediatric as well as Neonatal and Infant Nursing ever since. Distinguished nurses from abroad as well as a plethora of professors and physicians have taught at the school which has effectively made a mark in forming a tradition until today. The international concept of the school, including enhancing the young nurses' practice with experience from abroad is one of its most interesting features. The first Greek nursing schools rank among the first in the world.

All various traditional arts of Banyumas area support this area to be one famous region located in the periphery of West and Central Java with its unique cultural identity. In science learning, these traditional arts are very important aspect which can be implemented as a source of analog by students thinking a science concept analogically. This paper discusses a kind of Banyumas traditional art: the ebeg, and its cultural characteristics which can play a significant role in supporting elementary school students’ analogical thinking of a science material. The method used were literature and documentary studies. It is concluded that the ebeg provides many cultural characteristics which can be used as analog of elementary school science material, in terms of its music player’s motion, kinds of musical instruments played and its dancer motion.

The purpose of the present article is to compare the individual, peer, family, and school risk and protective factors for both traditional and cyber-bullying victimization. This article draws on data from 673 students from Victoria, Australia, to examine Grade 7 (aged 12-13 years) predictors of traditional and cyber-bullying victimization in Grade 9 (aged 14-15 years). Participants completed a modified version of the Communities That Care youth survey. There were few similarities and important differences in the predictors of traditional and cyber-bullying victimization. For Grade 9 cyber-bullying victimization, in the fully adjusted model, having been a victim of traditional bullying in Grade 7 and emotional control in Grade 7 were predictors. For Grade 9 traditional bullying victimization, predictors were Grade 7 traditional bullying victimization, association with antisocial peers, and family conflict, with family attachment and emotional control marginally statistically significant. The use of evidence-based bullying prevention programs is supported to reduce experiences of both traditional and cyber-bullying victimization, as is the implementation of programs to assist students to regulate their emotions effectively. In addition, traditional bullying victimization may be reduced by addressing association with antisocial friends, family conflict, and bonding to families. © The Author(s) 2014.

This study aimed to assess knowledge and skills in a respiratory physiology course in traditional versus problem-based learning (PBL) groups in two different medical schools. Two different undergraduate medical schools were selected for this study. The first medical school followed the traditional [lecture-based learning (LBL)] curriculum, and the second medical school followed the PBL curriculum. Sixty first-year male medical students (30 students from each medical school) volunteered; they were apparently healthy and of the same age, sex, nationality, and regional and cultural background. Students were taught respiratory physiology according to their curriculum for a period of 2 wk. At the completion of the study period, knowledge was measured based on a single best multiple-choice question examination, and skill was measured based on the objective structured practical examination in the lung function laboratory (respiratory physiology). A Student's t-test was applied for the analysis of the data, and the level of significance was set at P schools.

Full Text Available Accumulating epidemiological and clinical evidence shows that inflammation is an important risk factor for various human diseases. Thus, suppressing chronic inflammation has the potential to delay, prevent, and control various chronic diseases, including cerebrovascular, cardiovascular, joint, skin, pulmonary, blood, lymph, liver, pancreatic, and intestinal diseases. Various natural products from traditional Chinese medicine (TCM have been shown to safely suppress proinflammatory pathways and control inflammation-associated disease. In vivo and/or in vitro studies have demonstrated that anti-inflammatory effects of TCM occur by inhibition of the expression of master transcription factors (for example, nuclear factor-κB (NF-κB, pro-inflammatory cytokines (for example, tumor necrosis factor-α (TNF-α, chemokines (for example, chemokine (C-C motif ligand (CCL-24, intercellular adhesion molecule expression and pro-inflammatory mediators (for example, inducible nitric oxide synthase (iNOS and cyclooxygenase 2 (COX2. However, a handful of review articles have focused on the anti-inflammatory activities of TCM and explore their possible mechanisms of action. In this review, we summarize recent research attempting to identify the anti-inflammatory constituents of TCM and their molecular targets that may create new opportunities for innovation in modern pharmacology.

Cyberbullying perpetration (using communication technology to engage in bullying) is a recent phenomenon that has generated much concern. There are few prospective longitudinal studies of cyberbullying. The current article examines the individual, peer, family, and school risk factors for both cyber and traditional bullying (the latter is bullying that does not use technology) in adolescents. This article draws on a rich data set from the International Youth Development Study, a longitudinal study of students in Victoria, Australia and Washington State, United States, which began in 2002. In this article, data from almost 700 Victorian students recruited in grade 5 are analyzed to examine grade 7 (aged 12-13 years) predictors of traditional and cyberbullying perpetration in grade 9 (aged 14-15 years). Fifteen per cent of students engaged in cyberbullying, 21% in traditional bullying, and 7% in both. There are similarities and important differences in the predictors of cyber and traditional bullying. In the fully adjusted model, only prior engagement in relational aggression (a covert form of bullying, such as spreading rumors about another student) predicted cyberbullying perpetration. For traditional bullying, previous relational aggression was also predictive, as was having been a victim and perpetrator of traditional bullying, family conflict, and academic failure. The use of evidence-based bullying prevention programs is supported to reduce experiences of all forms of bullying perpetration (cyber, traditional, and relational aggression). In addition, for traditional bullying perpetration, addressing family conflict and student academic support are also important. Copyright © 2012 Society for Adolescent Health and Medicine.

Full Text Available Research from the past 40 years indicates that African American students are subjected to exclusionary discipline, including suspension and expulsion, at rates two to three times higher than their White peers (Children’s Defense Fund, 1975; Skiba, Michael, Nardo, & Peterson, 2002. Although this phenomenon has been studied extensively in traditional public schools, rates of racially disproportionate discipline in public Montessori schools have not been examined. The purpose of this study is to examine racial discipline disproportionality in Montessori public elementary schools as compared to traditional elementary schools. The Relative Rate Index (RRI is used as a measure of racially disproportionate use of out-of-school suspensions (Tobin & Vincent, 2011. Suspension data from the Office of Civil Rights Data Collection was used to generate RRIs for Montessori and traditional elementary schools in a large urban district in the Southeast. While statistically significant levels of racial discipline disproportionality are found in both the Montessori and traditional schools, the effect is substantially less pronounced in Montessori settings. These findings suggest that Montessori schools are not immune to racially disproportionate discipline and should work to incorporate more culturally responsive classroom management techniques. Conversely, the lower levels of racially disproportionate discipline in the Montessori schools suggests that further study of discipline in Montessori environments may provide lessons for traditional schools to promote equitable discipline.

Full Text Available Recent youth trends in the prevalence of e-cigarette and traditional cigarette use in Florida were examined in a cross-sectional, representative state sample from 2011 to 2014. Traditional cigarette use among youth declined during the study period. Experimentation with and past 30-day use of e-cigarettes among Florida youth tripled over 4 years. Past 30-day e-cigarette use exceeded traditional cigarette use in 2014; 10.8% of high school and 4.0% of middle school students reported recent e-cigarette use, compared with 8.7% of high school and 2.9% of middle school students for traditional cigarettes (P<0.001. By 2014, 20.5% of high school and 8.5% of middle school students reported ever use of e-cigarettes. Among ever e-cigarette users in 2014, 30.3% of high school and 42.2% of middle school students had never smoked traditional cigarettes. Given the concern that significant rates of e-cigarette use by U.S. adolescents may have a negative effect on public health, further review of e-cigarette advertising, marketing, sales, and use among U.S. youth is warranted.

In this study, the relationships between student beliefs about the nature of science, student attitudes, and conceptual change about the nature of forces were investigated within a traditional and within a constructivistic high school physics classroom. Students in both classrooms were honors students taking a first year high school physics course and were primarily white and middle to upper SES. Students in the traditional classroom were all high ability juniors, and physics instruction was integrated with pre-calculus. Students in the constructivistic classroom were a mixture of juniors and seniors. Due to the interrelated nature of these factors and the complexity of their interactions, a naturalistic inquiry design was chosen. The data sources included videotape of 7-9 weeks of instruction; analysis of the videotapes using the Secondary Teacher Analysis Matrix (Gallagher & Parker, 1995); field notes; pretest/posttest assessment with the Force Concept Inventory (Hestenes, Wells, & Swackhammer, 1992); student responses from the Views on Science-Technology-Society questionnaire (Aikenhead & Ryan, 1992), the Questionnaire for the Assessment of a Science Course (Chiappetta, 1995), and the Constructivist Learning Environment Survey (Taylor, Fraser, & White, 1994); student interviews; and teacher interviews. In the traditional classroom, (a) students did not think that physics was relevant to everyday experiences; (b) high conceptual change students were more likely to have an angular world view (Cobern, 1993) and have views more similar to the teacher's about the nature of science; and (c) high conceptual change students were able to develop an internally consistent understanding of the content; however, that content appeared to be isolated knowledge in some students. In the constructivistic classroom, (a) students saw physics as relevant and useful; (b) there was no difference in world view or agreement with the teacher's views on the nature of science between high

This multiple methods (Denzin, 1978) study investigated two instructional approaches, traditional module and electronic Problem-Based Learning instruction (e-PBL), used within a middle school engineering classroom focused on the variables of engagement, content knowledge, student self-assessment and teacher assessment of problem solving solutions. A non-equivalent group quasi-experimental research design (Creswell, 2015) was used on middle school students (N = 100) between those that received traditional module instruction (n = 51) and e-PBL instruction (n = 49). The qualitative approach of triangulation (Jick, 1979) was used to identify emergent themes for both between and within methods of data analysis on student engagement survey responses, two days of field observations notes, and six student interview transcripts. The quantitative results identified that students who received e-PBL instruction self-reported significantly greater engagement than those who received traditional module instruction. Further, there was a significant interaction effect between engineering content knowledge by group and gender as males who received e-PBL instruction had greater growth of content knowledge scores than males receiving traditional instruction, while females who received traditional instruction had greater growth of content knowledge scores than females in the e-PBL group. Through triangulation of the qualitative data, the emergent themes of the study suggest that hands-on learning produces higher levels of reported engagement independent of instructional method. The emergence of problem solving fatigue developed when both study groups reported a decline in engagement when entering into the final phase of the quantitative study suggesting that too many complex, ill-structured problems in rapid succession may negatively impact student engagement. Although females within the treatment group were most engaged, they did not achieve the knowledge growth of the females in the
Full Text Available Abstract For several years children at Joyce Public School have been rewriting traditional stories from localized cultural and linguistic perspectives, creating innovative, individualized narrative forms with digital technology. Our experimental multiliteracies research project is a collaboration of school and university teachers and researchers following a guided action research paradigm. The study has as one of its stated objectives the development of multilingual story retelling as a means of inexpensively supporting home language maintenance, fostering language awareness and aiding English as a second language learning in a community of high linguistic diversity. This paper tells our story thus far, focusing on how we have approached the creation of multilingual stories in heterogeneous, urban language classes, discussing stumbling blocks that have forced creative problem-solving and showcasing successes.

Traditional Chinese Medicines (TCMs) have been widely used for healing of different health problems for thousands of years. They have been used as therapeutic, complementary and alternative medicines. TCMs usually consist of dozens to hundreds of various compounds, which are extracted from raw...... herbal sources by aqueous or alcoholic solvents. Therefore, it is difficult to correlate the pharmaceutical effect to a specific lead compound in the TCMs. A detailed analysis of various components in TCMs has been a great challenge for modern analytical techniques in recent decades.

Full Text Available Physical activity is associated with numerous academic and health benefits. Furthermore, schools have been identified as an ideal location to promote physical activity as most youth attend school regularly from ages 5-18. Unfortunately, in an effort to increase academic learning time, schools have been eliminating traditional activity opportunities including physical education and recess. To combat physical inactivity in you, numerous organizations are promoting a Comprehensive School Physical Activity Program to encourage academic achievement and overall health. Comprehensive School Physical Activity Programs include five components and should be centered around 1 quality physical education, 2 physical activity before and after school, 3 physical activity during school (both recess and classroom activity, 4 staff involvement, and 5 family and community engagement.

Increasing children's physical activity at school is a national focus in the U.S. to address childhood obesity. While research has demonstrated associations between aspects of school environments and students' physical activity, the literature currently lacks a synthesis of evidence to serve as a practical, spatially-organized resource for school designers and decision-makers, as well as to point to pertinent research opportunities. This paper describes the development of a new practical tool: Physical Activity Design Guidelines for School Architecture. Its aims are to provide architects and designers, as well as school planners, educators, and public health professionals, with strategies for making K-12 school environments conducive to healthy physical activity, and to engage scientists in transdisciplinary perspectives toward improved knowledge of the school environment's impact. We used a qualitative review process to develop evidence-based and theory-driven school design guidelines that promote increased physical activity among students. The design guidelines include specific strategies in 10 school design domains. Implementation of the guidelines is expected to enable students to adopt healthier physical activity behaviors. The tool bridges a translational gap between research and environmental design practice, and may contribute to setting new industry and education standards.

Full Text Available ABSTRACT The dichloromethane extract of Plectranthus ornatus Codd., a tradicional medicinal plant, showed antibiotic activity with minimum inhibitory concentration (MIC values of 0.4 mg.mL-1 and 100 percent of biofilm inhibition against Staphylococcus aureus strains isolated from animals with mastitis infections. Based on these antibacterial activities, in addition to ethnopharmacological reports from healing men and farmers in Brazil, an herbal soap was produced from this active extract and was tested both in vitro and in vivo. In vivo assays conducted on these herbal soaps led to results similar to those previously conducted with the active extract. These results indicated the great potential of this plant for use as an excipient by preparing herbal antibacterial soaps as an alternative veterinary medicine aimed at controlling bovine mastitis infections on small Brazilian farms.

This article is an attempt to reconstruct the psychological achievements of the representatives of the Lvov-Warsaw School of historical psychology, virtually forgotten and unknown in the world's psychological literature. Kazimierz Twardowski (1866-1938), founder of the school, developed a philosophical and psychological program on the basis of (among other things) the theory of actions and products, including the research program that is now included in the thread of historical psychology. His student, Wladyslaw Witwicki (1878-1948), developed the cratism theory (the theory of power) on the basis Twardowski's assumptions, providing an alternative to Alfred Adler's theory of striving for superiority while also declaring it a few years before Adler. The consequence of Witwicki's theory and the methodological assumptions was the creation of psychobiography: the first nonpsychoanalytical psychobiography of Socrates (Witwicki, 1909, 1922) and the psychobiography of Jesus Christ (Witwicki, 1958). The school's activities weakened for political reasons, particularly the outbreak of the First World War. The members of the school dispersed after 1918, and they lost international connections with the world of science. Their significant achievements in the field of psychology remained unknown to psychologists for nearly a century. In this article, I would like to present the school's unique but unfinished program of reconstructing mental life through the psychological interpretation of cultural products (literature, arts, diaries), and its value for the practice of research in historical psychology. This program required additional development, but because of the war this never happened. Some of the school's theoretical findings and the first attempts to apply them have still significant value and show us the originality of Lvov-Warsaw School psychology.

We provide an extensive summary of the in vitro antibacterial properties of medicinal plants popularly used in Mexico to treat infections, and we discuss the ethnomedical information that has been published for these species. We carried out a bibliographic investigation by analyzing local and international peer-reviewed papers selected by consulting internationally accepted scientific databases from 1995 to 2014. We provide specific information about the evaluated plant parts, the type of extracts, the tested bacterial strains, and the inhibitory concentrations for each one of the species. We recorded the ethnomedical information for the active species, as well as their popular names and local distribution. Information about the plant compounds that has been identified is included in the manuscript. This review also incorporates an extensive summary of the available toxicological reports on the recorded species, as well as the worldwide registries of plant patents used for treating bacterial infections. In addition, we provide a list with the top plant species with antibacterial activities in this review RESULTS: We documented the in vitro antibacterial activities of 343 plant species pertaining to 92 botanical families against 72 bacterial species, focusing particularly on Staphylococcus aureus, Mycobacterium tuberculosis, Escherichia coli and Pseudomonas aeruginosa. The plant families Asteraceae, Fabaceae, Lamiaceae and Euphorbiaceae included the largest number of active species. Information related to popular uses reveals that the majority of the plants, in addition to treating infections, are used to treat other conditions. The distribution of Mexican plants extended from those that were reported to grow in just one state to those that grow in all 32 Mexican states. From 75 plant species, 225 compounds were identified. Out of the total plant species, only 140 (40.57%) had at least one report about their toxic effects. From 1994 to July 2014 a total of 11

Universities in the United Kingdom have been driven to work with a larger pool of potential students than just the more traditional student (middle-class white male), in order to tackle the widely-accepted skills-shortage in the fields of science, technology, engineering and mathematics (STEM), whilst honoring their commitment to fair access to higher education. Student-led outreach programs have contributed significantly to this drive. Two such programs run by postgraduate students at the University of Southampton are the Lightwave Roadshow and Southampton Accelerate!, which focus on photonics and particle physics, respectively. The program ambassadors have developed activities to enhance areas of the national curriculum through presenting fundamental physical sciences and their applications to optics and photonics research. The activities have benefitted significantly from investment from international organizations, such as SPIE, OSA and the IEEE Photonics Society, and UK research councils, in conjunction with university recruitment and outreach strategies. New partnerships have been formed to expand outreach programs to work in non-traditional environments to challenge stereotypes of scientists. This paper presents two case studies of collaboration with education learning centers at Salisbury Cathedral and Winchester Cathedral. The paper outlines workshops and shows developed for pupils aged 6-14 years (UK key stages 2-4) on the electromagnetic spectrum, particle physics, telecommunications and the human eye using a combination of readily obtainable items, hand-built kits and elements from the EYEST Photonics Explorer kit. The activities are interactive to stimulate learning through active participation, complement the UK national curriculum and link the themes of science with the non-traditional setting of a cathedral. We present methods to evaluate the impact of the activity and tools to obtain qualitative feedback for continual program improvement. We also

Full Text Available In Portugal in recent decades, just like in other welcoming countries, immigrants have reached levels of entrepreneurial activity that are higher than those of autochthonous citizens. However, a deeper analysis of the official data shows that not all immigrant groups have the same tendency to become entrepreneurs. In this respect, the Chinese stand out as being the group with the highest ratio of entrepreneurial activity in Portugal, despite the fact that their migration is a relatively recent phenomenon. What factors can explain the Chinese community’s disproportionate rate of entrepreneurial initiative? Do they possess any particular resources that make them more enterprising than the autochthonous population, or than other groups of immigrants? Does the context of Portugal hamper certain opportunities or in some way limit their economic integration into the job market? Do we find similar business strategies among other Chinese entrepreneurs residing in welcoming societies apart from that of Portugal? Why did Chinese business initiative grow at such an exceptional rate in Portugal in the late 1990s? By seeking answers to these questions, this article attempts to examine Chinese business strategies in Portugal, as well as their exceptional success rate in comparison with other entrepreneurial immigrants. To that end, the author has analysed the data gathered in a survey carried out on 309 Chinese entrepreneurs resident in Portugal (see Oliveira, 2005.

BACKGROUND: Movement integration (MI) into traditional classroom teaching is a promising opportunity for children to increase physical activity (PA). Education outside the classroom (EOtC) can be regarded as MI, and has increased children's PA in case studies. The aim of this study....... Differences in proportion of time spent in PA intensities were tested using mixed-effects regression models. RESULTS: More moderate-to-vigorous physical activity (MVPA) occurred on days with physical education (PE) than days with EOtC (girls 0.79%, p = .001, CI = .26% to 1.31%; boys 1.35%, p = .003, CI = .32......% to 2.38%), while no difference was found between EOtC days and school days without EOtC and PE. Light physical activity (LPA) was higher on EOtC days than school days without EOtC and PE (girls 2.43% p

In most states, there are two routes to teacher licensure; traditional and alternative. The alternative route provides an accelerated entry into the classroom, often without the individual engaging in education coursework or a practicum. No matter the route, teaching skills continue to be learned by novice teachers while in the classroom with the guidance of a school-based mentor. In this study, the perceptions of mentor teachers of traditionally and alternatively licensed high school science teachers were compared with respect to mentees' science teaching competency. Further, the study explored the novice teachers' self-perception of their teaching competency. A survey, consisting of 56 Likert-type questions, was completed by mentors (N = 79) and novice high school science teachers (N = 83) in six northeastern states. The results revealed a statistically significant difference in the perceptions of the mentors of traditionally and alternatively licensed novice high school science teachers in the areas of general pedagogical knowledge, pedagogical content knowledge and professional growth, with more favorable perceptions recorded by mentors of traditionally licensed science teachers. There were no differences in the perceptions of the mentors with respect to novice high school teachers' content knowledge. There was no statistical difference in the self-perceptions of competency of the novice teachers. While alternative routes to licensure in science may be a necessity, the results of this study indicate that the lack of professional preparation may need to be addressed at the school level through the agency of the mentor. This study indicates that mentors must be prepared to provide alternatively licensed novice teachers with different assistance to that given to traditionally licensed novice teachers. School districts are urged to develop mentoring programs designed to develop the teaching competency of all novice teachers regardless of the route that led them

Full Text Available The Bapedi is an ethnic group in South Africa whose traditional music is not well documented. For this article, 31 traditional Pedi religious songs from 11 elderly Bapedi women in Sekhukhune, Limpopo Province, South Africa were collected and analysed. They were analysed using religious, musicological and contextual perspectives, and two choruses were selected. Eight Sepedi-speaking children from a school choir at Baxoxele Primary School in Soshanguve were observed whilst learning these two choruses. Repetition was used as a powerful, rhetorical and expressive device, skilfully employed to express and internalise faith and to impart dominant emotions. Informal discussions with teachers indicated that the children showed an improvement in their concentration and attitude to schoolwork. Learning these two choruses also unlocked some creative talent and improved their social skills. The joyous nature, rhythmic foundation, harmonic simplicity, and combination of intellect and emotion as well as the repetitiveness and briefness of these songs appealed to both children and adults. It was concluded that for the preservation of traditional Pedi religious music and culture there is an urgent need for the collection and documentation of traditional Pedi religious songs. In recognising their identity, such songs could contribute to the attitudes and cultural values of Sepedi-speaking children. Similar projects are suggested for the other 10 language groups in South Africa. Analisering van tradisionele godsdienstige Pedi-liedere vir gebruik in die laerskoolkurrikulum.

The 'active school' model offers promise for promoting school-based physical activity (PA); however, few intervention trials have evaluated its effectiveness. Thus, our purpose was to: (1) describe Action Schools! BC (AS! BC) and its implementation (fidelity and feasibility) and (2) evaluate the impact of AS! BC on school provision of PA. Ten elementary schools were randomly assigned to one of the three conditions: Usual Practice (UP, three schools), Liaison (LS, four schools) or Champion (CS, three schools). Teachers in LS and CS schools received AS! BC training and resources but differed on the level of facilitation provided. UP schools continued with regular PA. Delivery of PA during the 11-month intervention was assessed with weekly Activity Logs and intervention fidelity and feasibility were assessed using Action Plans, workshop evaluations, teacher surveys and focus groups with administrators, teachers, parents and students. Physical activity delivered was significantly greater in LS (+67.4 min/week; 95% CI: 18.7-116.1) and CS (+55.2 min/week; 95% CI: 26.4-83.9) schools than UP schools. Analysis of Action Plans and Activity Logs showed fidelity to the model and moderate levels of compliance (75%). Teachers were highly satisfied with training and support. Benefits of AS! BC included positive changes in the children and school climate, including provision of resources, improved communication and program flexibility. These results support the use of the 'active school' model to positively alter the school environment. The AS! BC model was effective, providing more opportunities for "more children to be more active more often" and as such has the potential to provide health benefits to elementary school children.

School-based interventions for increasing physical activity among children are widespread, however there is still a lack of knowledge about how school context factors are linked to implementation quality and effectiveness of programmes. The aim of this paper is to examine teacher-perceived effectiveness of a Danish national classroom-based health programme 'Active Around Denmark' and in particular, to investigate whether perceptions vary as a function of school social context factors. After completion of the programme all teachers (N = 5.892) received an electronic questionnaire. 2.097 completed the questionnaire (response rate 36%) and 1.781 datasets could be used for analysis. The teachers were asked about their perceptions of changes in children's attitudes towards and levels of physical activity after the competition. Our results indicated that certain contextual factors, such as schools' prioritization of health promotion, teachers' support by their school principal in implementation as well as teacher's satisfaction with the school' physical environment made a significant difference in teacher-perceived effectiveness. To conclude, teacher-perceived effectiveness of the health programme does vary as a function of school social context factors.

Full text: Recent years Hematogists and Pediatricians pay more attention to the issue of disturbance of microelement homeostasis which is the most important in formation of microelementosis in children. To prevent and to treat the deficient forms of microelementosis the determination of microelement contents in traditional food of the population in any particular region is an issue of great importance. Provision of school age children with essential microelements and deficiency of many micronutrients are not sufficiently studied. In this aspect the issue of microelement contents in food stuffs of the children of Zarafshan valley is not enough investigated. Therefore, it is advisable to study the specific weight of microelements such as iron, zinc, copper, cobalt and manganese in vegetable and animal products and phytomedium which are consumed as the traditional food of the population of this region. We have studied 47 types of food stuffs mainly of vegetable and animal origin as well as widely used phytomedium. Microelement concentration in food stuffs were defined by neutron-activation analysis method worked out at Nuclear Physics Institute Republic of Uzbekistan. For the first time we have investigated national dishes - sumalak, halisa, shinni which are the essential part of traditional food of Central Asian population and the contents of microelements being studied. As per results of investigation it was found out that the most highest contents of iron was in dried apricot (358 mg/kg), then in black (180 mg/kg) and white (110 mg/kg) raisins. National dish - shinni ( the grapes syrup) contained iron equal to 103 mg/kg, local apple - 100 mg/kg. It should be noted that not only raisins and shinni are rich with iron but the decoction from wild vineyard stalks too which contains 366 mg/l. Moderate iron contents ( 50-100 mg/kg) was found in the following dried fruits: blackberry, haw, bitter and sweet almond, dried fig, and mulberry. Low concentration of iron (less

Traditional performance expectations and career advancement paths for academic physicians persist despite dramatic transformations in the academic workflow, workload, and workforce over the past 20 years. Although the academic physician's triple role as clinician, researcher, and educator has been lauded as the ideal by academic health centers, current standards of excellence for promotion and tenure are based on outdated models. These models fail to reward collaboration and center around rigid career advancement plans that do little to accommodate the changing needs of individuals and organizations. The authors describe an innovative, comprehensive, multipronged initiative at the Perelman School of Medicine at the University of Pennsylvania to initiate change in the culture of academic medicine and improve academic productivity, job satisfaction, and overall quality of life for junior faculty. As a key part of this intervention, task forces from each of the 13 participating departments/divisions met five times between September 2010 and January 2011 to produce recommendations for institutional change. The authors discuss how this initiative, using principles adopted from business transformation, generated themes and techniques that can potentially guide workforce environment innovation in academic health centers across the United States. Recommendations include embracing a promotion/tenure/evaluation system that supports and rewards tailored individual academic career plans; ensuring leadership, decision-making roles, and recognition for junior faculty; deepening administrative and team supports for junior faculty; and solidifying and rewarding mentorship for junior faculty. By doing so, academic health centers can ensure the retention and commitment of faculty throughout all stages of their careers.

Full Text Available Abstract Background The purpose of this paper is to review relationships of academic performance and some of its determinants to participation in school-based physical activities, including physical education (PE, free school physical activity (PA and school sports. Methods Linkages between academic achievement and involvement in PE, school PA and sport programmes have been examined, based on a systematic review of currently available literature, including a comprehensive search of MEDLINE (1966 to 2007, PSYCHINFO (1974 to 2007, SCHOLAR.GOOGLE.COM, and ERIC databases. Results Quasi-experimental data indicate that allocating up to an additional hour per day of curricular time to PA programmes does not affect the academic performance of primary school students negatively, even though the time allocated to other subjects usually shows a corresponding reduction. An additional curricular emphasis on PE may result in small absolute gains in grade point average (GPA, and such findings strongly suggest a relative increase in performance per unit of academic teaching time. Further, the overwhelmingly majority of such programmes have demonstrated an improvement in some measures of physical fitness (PF. Cross-sectional observations show a positive association between academic performance and PA, but PF does not seem to show such an association. PA has positive influences on concentration, memory and classroom behaviour. Data from quasi-experimental studies find support in mechanistic experiments on cognitive function, pointing to a positive relationship between PA and intellectual performance. Conclusion Given competent providers, PA can be added to the school curriculum by taking time from other subjects without risk of hindering student academic achievement. On the other hand, adding time to "academic" or "curricular" subjects by taking time from physical education programmes does not enhance grades in these subjects and may be detrimental to health.

Traditional medicinal plants have long been used in Ethiopia to treat human and livestock ailments. Despite a well-documented rich tradition of medicinal plant use in the country, their direct antimicrobial effects are still poorly known. To investigate the antimicrobial activity of 19 medicinal plant species that were selected based on the ethnobotanical information on their traditional use to treat infectious diseases in Ankober District. About 23 different ethanol extracts of plants obtained by maceration of various parts of 19 medicinal plant species were studied for potential antimicrobial activity using a broth microdilution method against Bacillus cereus, Bacteroides fragilis, Candida albicans, Clostridium perfringens, Enterococcus faecalis, Escherichia coli, Listeria monocytogenes, Pseudomonas aeruginosa, Salmonella enteritidis, Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pyogenes. Plant extracts from Embelia schimperi Vatke (Myrsinaceae) showed the strongest antibacterial activity with a minimum inhibitory concentration (MIC) value of 64 µg/ml against B. cereus, L. monocytogenes, and S. pyogenes. Growth inhibitory activities were also observed for extracts of Ocimum lamiifolium Hochst. (Lamiaceae) against S. pyogenes, and those of Rubus steudneri Schweinf. (Rosaceae) against S. epidermidis at an MIC value of 128 µg/ml. Generally, 74% of ethanol extracts (17 extracts) showed antimicrobial activity against one or more of the microbial strains tested at an MIC value of 512 µg/ml or below. Results confirm the antimicrobial role of traditional medicinal plants of Ankober and warrant further investigations on promising medicinal plant species so as to isolate and characterise chemicals responsible for the observed strong antimicrobial activities.

Full Text Available Traditional Chinese herbal medicines (TCHMs were tested for their ability of antiquorum sensing. Water extracts of Rhubarb, Fructus gardeniae, and Andrographis paniculata show antiquorumsensing activity when using Chromobacterium violaceum CV12472 as reporter; the sub-MIC concentrations of these TCHMs were tested against AHL-dependent phenotypic expressions of PAO1. Results showed significant reduction in pyocyanin pigment, protease, elastase production, and biofilm formation in PAO1 without inhibiting the bacterial growth, revealing that the QSI by the extracts is not related to static or killing effects on the bacteria. The results indicate a potential modulation of bacterial cell-cell communication, P. aeruginosa biofilm, and virulence factors by traditional Chinese herbal medicine. This study introduces not only a new mode of action for traditional Chinese herbal medicines, but also a potential new therapeutic direction for the treatment of bacterial infections, which have QSI activity and might be important in reducing virulence and pathogenicity of pathogenic bacteria.

In South Africa, the genus Helichrysum is widely used in traditional medicine. The uses are well documented although renaming of species and the resulting confusing taxonomic nomenclature may cause uncertainty as to which specific species was referred to in some reports. The aim of this paper is to present a collated and coherent overview of the documented traditional uses of Helichrysum species and to update the botanical identity of previously studied species. Databases (Scifinder, ISI Web of Knowledge) and several books were used to collect in information on South African Helichrysum species. The traditional uses, chemistry and biological activity of Helichrysum species have been summarized. It was attempted to give clarity as to exactly which species is refer to in the ethnobotanical literature. Although a large number of ethnopharmacological uses have been documented and the chemistry of the genus has been studied extensively, only a few South African species have been investigated for their biological activity.

GalileoMobile is an itinerant science education initiative run on a voluntary basis by an international team of astronomers, educators, and science communicators. Our team's main goal is to make astronomy accessible to schools and communities around the globe that have little or no access to outreach actions. We do this by performing teacher workshops, activities with students, and donating educational material. Since the creation of GalileoMobile in 2008, we have travelled to Chile, Bolivia, Peru, India, and Uganda, and worked with 56 schools in total. Our activities are centred on the GalileoMobile Handbook of Activities that comprises around 20 astronomical activities which we adapted from many different sources, and translated into 4 languages. The experience we gained in Chile, Bolivia, Peru, India, and Uganda taught us that (1) bringing experts from other countries was very stimulating for children as they are naturally curious about other cultures and encourages a collaboration beyond borders; (2) high-school students who were already interested in science were always very eager to interact with real astronomers doing research to ask for career advice; (3) inquiry-based methods are important to make the learning process more effective and we have therefore, re-adapted the activities in our Handbook according to these; (4) local teachers and university students involved in our activities have the potential to carry out follow-up activities, and examples are those from Uganda and India.

Background. Traditional Chinese medicine encompasses a well established alternate system of medicine based on a broad range of herbal formulations and is practiced extensively in the region for the treatment of a wide variety of diseases. In recent years, several reports describe in depth studies of the molecular ingredients of traditional Chinese medicines on the biological activities including anti-bacterial activities. The availability of a well-curated dataset of molecular ingredients of traditional Chinese medicines and accurate in-silico cheminformatics models for data mining for antitubercular agents and computational filters to prioritize molecules has prompted us to search for potential hits from these datasets. Results. We used a consensus approach to predict molecules with potential antitubercular activities from a large dataset of molecular ingredients of traditional Chinese medicines available in the public domain. We further prioritized 160 molecules based on five computational filters (SMARTSfilter) so as to avoid potentially undesirable molecules. We further examined the molecules for permeability across Mycobacterial cell wall and for potential activities against non-replicating and drug tolerant Mycobacteria. Additional in-depth literature surveys for the reported antitubercular activities of the molecular ingredients and their sources were considered for drawing support to prioritization. Conclusions. Our analysis suggests that datasets of molecular ingredients of traditional Chinese medicines offer a new opportunity to mine for potential biological activities. In this report, we suggest a proof-of-concept methodology to prioritize molecules for further experimental assays using a variety of computational tools. We also additionally suggest that a subset of prioritized molecules could be used for evaluation for tuberculosis due to their additional effect against non-replicating tuberculosis as well as the additional hepato-protection offered by

Full Text Available Background. We conducted a comparative effectiveness analysis to evaluate the difference in the amount of physical activity children engaged in when enrolled in a physical activity-enhanced after-school program based in a community recreation center versus a standard school-based after-school program. Methods. The study was a natural experiment with 54 elementary school children attending the community ASP and 37 attending the school-based ASP. Accelerometry was used to measure physical activity. Data were collected at baseline, 6 weeks, and 12 weeks, with 91% retention. Results. At baseline, 43% of the multiethnic sample was overweight/obese, and the mean age was 7.9 years (SD = 1.7. Linear latent growth models suggested that the average difference between the two groups of children at Week 12 was 14.7 percentage points in moderate-vigorous physical activity (P<.001. Cost analysis suggested that children attending traditional school-based ASPs—at an average cost of $17.67 per day—would need an additional daily investment of $1.59 per child for 12 weeks to increase their moderate-vigorous physical activity by a model-implied 14.7 percentage points. Conclusions. A low-cost, alternative after-school program featuring adult-led physical activities in a community recreation center was associated with increased physical activity compared to standard-of-care school-based after-school program.

This article describes policies, practices, and facilities that form the physical activity climate in Minneapolis/St. Paul, Minnesota metro area middle and high schools and examines how the physical activity climate varies by school characteristics, including public/private, school location and grade level. Surveys examining school physical activity practices, policies and environment were administered to principals and physical education department heads from 115 middle and high schools participating in the Transdisciplinary Research on Energetics and Cancer-Identifying Determinants of Eating and Activity (TREC-IDEA) study. While some supportive practices were highly prevalent in the schools studied (such as prohibiting substitution of other classes for physical education); other practices were less common (such as providing opportunity for intramural (noncompetitive) sports). Public schools vs. private schools and schools with a larger school enrollment were more likely to have a school climate supportive of physical activity. Although schools reported elements of positive physical activity climates, discrepancies exist by school characteristics. Of note, public schools were more than twice as likely as private schools to have supportive physical activity environments. Establishing more consistent physical activity expectations and funding at the state and national level is necessary to increase regular school physical activity.

SCALE-UP–type classrooms, originating with the Student-Centered Active Learning Environment with Upside-down Pedagogies project, are designed to facilitate active learning by maximizing opportunities for interactions between students and embedding technology in the classroom. Positive impacts when active learning replaces lecture are well documented, both in traditional lecture halls and SCALE-UP–type classrooms. However, few studies have carefully analyzed student outcomes when comparable active learning–based instruction takes place in a traditional lecture hall and a SCALE-UP–type classroom. Using a quasi-experimental design, we compared student perceptions and performance between sections of a nonmajors biology course, one taught in a traditional lecture hall and one taught in a SCALE-UP–type classroom. Instruction in both sections followed a flipped model that relied heavily on cooperative learning and was as identical as possible given the infrastructure differences between classrooms. Results showed that students in both sections thought that SCALE-UP infrastructure would enhance performance. However, measures of actual student performance showed no difference between the two sections. We conclude that, while SCALE-UP–type classrooms may facilitate implementation of active learning, it is the active learning and not the SCALE-UP infrastructure that enhances student performance. As a consequence, we suggest that institutions can modify existing classrooms to enhance student engagement without incorporating expensive technology. PMID:27909018

To carry out a preliminary investigation of the biological activity of Kombucha beverages from Camellia sinensis L. (black tea) and Satureja montana L. (winter savory tea), that have consuming acidity. Cell growth effect was measured by sulforhodamine B colorimetric assay on HeLa (cervix epithelioid carcinoma), HT-29 (colon adenocarcinoma), and MCF-7 (breast adenocarcinoma). Antimicrobial activity to bacteria, yeasts and moulds was determined by agar-well diffusion method. Consuming Kombuchas had the most expressive antimicrobial activity against all investigated bacteria, except Sarcina lutea, while unfermented tea samples had no activity. Traditional Kombucha showed higher activity against Staphylococcus aureus and Escherichia coli than acetic acid, while both neutralized Kombuchas had bacteriostatic activity on Salmonella enteritidis. Examined Kombuchas did not stimulate cell proliferation of the investigated cell lines. Antiproliferative activity of winter savory tea Kombucha was comparable to that of traditional Kombucha made from black tea. Furthermore, in HeLa cell line Satureja montana L. Kombucha induced cell growth inhibition by 20% (IC20) at lower concentration compared to the activity of water extract of Satureja montana L. obtained in our previous research. Presence of more active antiproliferative component(s) in Satureja montana L. Kombucha compared to Satureja montana L. water extract and antimicrobial component(s) other than acetic acid in both Kombuchas is suggested.

This study sought to determine the influence of individual factors on active transportation to school among Danish seventh graders and whether school district factors are associated with such behaviour independently of individual factors. Mixed effects logistic regression models determined the effects of individual (gender, family affluence, enjoyment of school and academic performance) and school district factors (educational level, household savings, land use and size) on active transportation to school (by foot, bicycle or other active means) among 10 380 pupils aged 13-15 years nested in 407 school districts. Of all students, 64.4% used active transportation to school daily. Boys, those with perceived higher school performance and those with lower family affluence were more likely to use active transportation to school. After adjustment for all individual factors listed above, high household savings at the school district level was associated with higher odds of active transportation to school. As factors of land use, low level of farming land use and high proportion of single houses were associated with active transportation to school. Policies aiming at reducing social inequalities at the school district level may enhance active transportation to school. School districts with farming land use face barriers for active transportation to school, requiring special policy attention.

Context-based curriculum reforms in chemistry education are thought to bring greater diversity to the ways in which chemistry teachers organize their teaching. First and foremost, students are expected to perceive this diversity. However, empirical research on how students perceive their teacher's teaching in context-based chemistry classrooms, and whether this teaching differs from traditional chemistry lessons, is scarce. This study aims to develop our understanding of what teaching looks like, according to students, in context-based chemistry classrooms compared with traditional chemistry classrooms. As such, it might also provide a better understanding of whether teachers implement and attain the intentions of curriculum developers. To study teacher behaviour we used three theoretical perspectives deemed to be important for student learning: a content perspective, a learning activities perspective, and an interpersonal perspective. Data were collected from 480 students in 24 secondary chemistry classes in the Netherlands. Our findings suggest that, according to the students, the changes in teaching in context-based chemistry classrooms imply a lessening of the emphasis on fundamental chemistry and the use of a teacher-centred approach, compared with traditional chemistry classrooms. However, teachers in context-based chemistry classrooms seem not to display more 'context-based' teaching behaviour, such as emphasizing the relation between chemistry, technology, and society and using a student-centred approach. Furthermore, students in context-based chemistry classrooms perceive their teachers as having less interpersonal control and showing less affiliation than teachers in traditional chemistry classrooms. Our findings should be interpreted in the context of former and daily experiences of both teachers and students. As only chemistry is reformed in the schools in which context-based chemistry is implemented, it is challenging for both students and teachers to

Traditional bullying has received considerable research but the emerging phenomenon of cyber-bullying much less so. Our study aims to investigate environmental and psychological factors associated with traditional and cyber-bullying. In a school-based 2-year prospective survey, information was collected on 1,344 children aged 10 including bullying behavior/experience, depression, anxiety, coping strategies, self-esteem, and psychopathology. Parents reported demographic data, general health, and attention-deficit hyperactivity disorder (ADHD) symptoms. These were investigated in relation to traditional and cyber-bullying perpetration and victimization at age 12. Male gender and depressive symptoms were associated with all types of bullying behavior and experience. Living with a single parent was associated with perpetration of traditional bullying while higher ADHD symptoms were associated with victimization from this. Lower academic achievement and lower self esteem were associated with cyber-bullying perpetration and victimization, and anxiety symptoms with cyber-bullying perpetration. After adjustment, previous bullying perpetration was associated with victimization from cyber-bullying but not other outcomes. Cyber-bullying has differences in predictors from traditional bullying and intervention programmes need to take these into consideration.
Full Text Available Abstract Background The evolution and spread of antibiotic resistance, as well as the evolution of new strains of disease causing agents, is of great concern to the global health community. Our ability to effectively treat disease is dependent on the development of new pharmaceuticals, and one potential source of novel drugs is traditional medicine. This study explores the antibacterial properties of plants used in Haudenosaunee traditional medicine. We tested the hypothesis that extracts from Haudenosaunee medicinal plants used to treat symptoms often caused by bacterial infection would show antibacterial properties in laboratory assays, and that these extracts would be more effective against moderately virulent bacteria than less virulent bacteria. Methods After identification and harvesting, a total of 57 different aqueous extractions were made from 15 plant species. Nine plant species were used in Haudenosaunee medicines and six plant species, of which three are native to the region and three are introduced, were not used in traditional medicine. Antibacterial activity against mostly avirulent (Escherichia coli, Streptococcus lactis and moderately virulent (Salmonella typhimurium, Staphylococcus aureus microbes was inferred through replicate disc diffusion assays; and observed and statistically predicted MIC values were determined through replicate serial dilution assays. Results Although there was not complete concordance between the traditional use of Haudenosaunee medicinal plants and antibacterial activity, our data support the hypothesis that the selection and use of these plants to treat disease was not random. In particular, four plant species exhibited antimicrobial properties as expected (Achillea millefolium, Ipomoea pandurata, Hieracium pilosella, and Solidago canadensis, with particularly strong effectiveness against S. typhimurium.

Academic activity during internship is essentially practical and ward rounds are traditionally considered the cornerstone of clinical education. However, the efficacy and effectiveness of ward rounds for learning purposes have been under-investigated and it is necessary to assess alternative educational paradigms for this activity. This study aimed to compare the educational effectiveness of ward rounds conducted with two different learning methodologies. Student subjects were first tested on 30 true/false questions to assess their initial degree of knowledge on pneumonia and diarrhoea. Afterwards, they attended ward rounds conducted using an active and a traditional learning methodology. The participants were submitted to a second test 48hours later in order to assess knowledge acquisition and were asked to answer two questions about self-directed learning and their opinions on the two learning methodologies used. Seventy-two medical students taking part in a paediatric clinic rotation were enrolled. The active methodology proved to be more effective than the traditional methodology for the three outcomes considered: knowledge acquisition (33 students [45.8%] versus 21 students [29.2%]; p=0.03); self-directed learning (38 students [52.8%] versus 11 students [15.3%]; pmethods (61 students [84.7%] versus 38 students [52.8%]; ptraditional methodology in a ward-based context. This study seems to be valuable in terms of the new evidence it demonstrates on learning methodologies in the context of the ward round. © Blackwell Publishing Ltd 2011.

Vegetables have been believed to exhibit antioxidant activities due to its phenolic content. Thus, this study was carried out to determine the total phenolic content of water and ethanolic extracts of Malaysian traditional vegetables and assess their antioxidant activities. Eight samples of Malaysian traditional vegetables were dried and extracted its phenolic compounds using water and ethanolic solvent. Total phenolic content of the extracts were compared and evaluated using Folin-Ciocalteu and Prussian Blue reagent. The antioxidant activity were assessed using ferric thiocyanate assay and DPPH free radical scavenging assays. Results found that total phenolic content of water extracts ranged from 7.08 to 14.76 mg GAE (Folin-Ciocalteu assay) and 3.50 to 7.82 mg GAE (Prussian Blue assay). However, the content of phenolic of ethanolic extracts ranged from 5.21 to 15.86 mg GAE (Folin-Ciocalteu assay), and 1.84 to 11.54 mg GAE (Prussian Blue assay). The highest antioxidant activity was observed in water extracts of Etlingera elatior (75.6 %) and ethanolic extracts of Sauropus androgynus (78.1 %). Results also found that the best half maximal inhibitory concentration or IC 50 were demonstrated by water and ethanolic extracts of Sauropus androgynus which demonstrated 0.077 mg/mL and 0.078 mg/ mL, respectively. Hence, this study obtained that most of the Malaysian traditional vegetables have a potential source of natural antioxidant. (author)
Full Text Available Traditional Chinese Medicine (TCM has been used to treat diseases in China for thousands of years. TCM compositions are complex, using as their various sources plants, animals, fungi, and minerals. Polysaccharides are one of the active and important ingredients of TCMs. Polysaccharides from TCMs exhibit a wide range of biological activities in terms of immunity- modifying, antiviral, anti-inflammatory, anti-oxidative, and anti-tumor properties. With their widespread biological activities, polysaccharides consistently attract scientist's interests, and the studies often concentrate on the extraction, purification, and biological activity of TCM polysaccharides. Currently, numerous studies have shown that the modification of polysaccharides can heighten or change the biological activities, which is a new angle of polysaccharide research. This review highlights the current knowledge of TCM polysaccharides, including their extraction, purification, modification, and biological activity, which will hopefully provide profound insights facilitating further research and development.

Several plant species belonging to the genus Aspidosperma are traditionally used in Brazil and other Meso- and South American countries for the treatment of malaria and fevers. These traditional uses were motivation for this review. A literature survey completed for this review has identified scientific bibliographical references to the use of 24 Aspidosperma species to treat malaria/fevers and to 19 species that have had their extracts and/or alkaloids evaluated, with good results, for in vitro and/or in vivo antimalarial activity. Indole alkaloids are typical constituents of Aspidosperma species. However, only 20 out of more than 200 known indole alkaloids isolated from this genus have been assayed for antimalarial activity. These data support the potential of Aspidosperma species as sources of antimalarials and the importance of research aimed at validating their use in the treatment of human malaria.

In a survey conducted with 1,107 parents (590 mothers, M age=38.8 yr., SD=5.8; 517 fathers, M age=41.3 yr., SD=6.0) and 123 teachers (82 women, M age=41.1 yr., SD=9.2; 41 men, M age=41.3 yr., SD=9.1) in coastal rural Southern Ostrobothnia, Finland, an assessment of the relative responsibility of the family in comparison with that of school in the teaching of various skills to children was made. Parents and teachers agreed that the school carries 30-40% of the responsibility for the teaching of socio-emotional skills, such as conflict resolution, norms and values, self-esteem, sense of justice and responsibility, and close human relations. They also agreed that school carries 50% of the responsibility for providing information about sexuality and drugs. Fathers opined that school carried a greater responsibility in teaching skills than mothers did.

Full Text Available Abstract Background The integration of traditional ecological knowledge (TEK into formal school curricula may be a key tool for the revitalisation of biocultural diversity, and has the potential to improve the delivery of educational objectives. This paper explores perceptions of the value of TEK to formal education curricula on Malekula Island, Vanuatu. We conducted 49 interviews with key stakeholders (local TEK experts, educators, and officials regarding the use of the formal school system to transmit, maintain, and revitalise TEK. Interviews also gathered information on the areas where TEK might add value to school curricula and on the perceived barriers to maintaining and revitalising TEK via formal education programs. Results Participants reported that TEK had eroded on Malekula, and identified the formal school system as a principal driver. Most interviewees believed that if an appropriate format could be developed, TEK could be included in the formal education system. Such an approach has potential to maintain customary knowledge and practice in the focus communities. Participants identified several specific domains of TEK for inclusion in school curricula, including ethnomedical knowledge, agricultural knowledge and practice, and the reinforcement of respect for traditional authority and values. However, interviewees also noted a number of practical and epistemological barriers to teaching TEK in school. These included the cultural diversity of Malekula, tensions between public and private forms of knowledge, and multiple values of TEK within the community. Conclusions TEK has potential to add value to formal education systems in Vanuatu by contextualising the content and process of curricular delivery, and by facilitating character development and self-awareness in students. These benefits are congruent with UNESCO-mandated goals for curricular reform and provide a strong argument for the inclusion of TEK in formal school systems. Such

Influenza is still a serious threat to human health with significant morbidity and mortality. The emergence of drug-resistant influenza viruses poses a great challenge to existing antiviral drugs. Traditional Chinese medicines (TCMs) may be an alternative to overcome the challenge. Here, 10 oral proprietary Chinese medicines were selected to evaluate their anti-influenza activities. These drugs exhibit potent inhibitory effects against influenza A H1N1, influenza A H3N2, and influenza B virus. Importantly, they demonstrate potent antiviral activities against drug-resistant strains. In the study of mechanisms, we found that Xiaoqinglong mixture could increase antiviral interferon production by activating p38 MAPK, JNK/SAPK pathway, and relative nuclear transcription factors. Lastly, our studies also indicate that some of these medicines show inhibitory activities against EV71 and CVB strains. In conclusion, the 10 traditional Chinese medicines, as kind of compound combination medicines, show broad-spectrum antiviral activities, possibly also including inhibitory activities against strains resistant to available antiviral drugs.
Full Text Available Traditional kombucha is a fermented black tea extract and sugar. Sweetened black tea (10% w/v and wheatgrass juice (WGJ were mixed in various ratios and used as fermentation substrate for enhancing phenolic compounds and antioxidant activity. Starter, comprising of yeast (Dekkera bruxellensis and acetic acid bacteria (Gluconacetobacter rhaeticus and Gluconobacter roseus, was inoculated at 20% (v/v, and fermented statically at 29 ± 1°C for 12 days. The results showed that the total phenolic and flavonoid contents and antioxidant activity of the modified kombucha were higher than those of traditional preparations. All WGJ-blended kombucha preparations were characterized as having higher concentrations of various phenolic compounds such as gallic acid, catechin, caffeic acid, ferulic acid, rutin, and chlorogenic acid as compared to traditional ones. Addition of WGJ resulted in the 1,1-diphenyl-2-picrylhydrazyl (DPPH scavenging ability of kombucha being > 90%, while the oxygen radical absorbance capacity increased from 5.0 μmol trolox equivalents/mL to 12.8 μmol trolox equivalents/mL as the ratio of WGJ increased from 0% to 67% (v/v. The highest antioxidant activity was obtained using a 1:1 (v/v black tea decoction to WGJ ratio and 3 days of fermentation, producing various types of phenolic acids. These results suggest that intake of fermented black tea enhanced with wheatgrass juice is advantageous over traditional kombucha formulas in terms of providing various complementary phenolics and might have more potential to reduce oxidative stress.

Traditional Chinese medicine (TCM), as a unique form of natural medicine, has been used in Chinese traditional therapeutic systems over two thousand years. Active components in Chinese herbal medicine are the material basis for the prevention and treatment of diseases. Research on drug-protein binding is one of the important contents in the study of early stage clinical pharmacokinetics of drugs. Plasma protein binding study has far-reaching influence on the pharmacokinetics and pharmacodynamics of drugs and helps to understand the basic rule of drug effects. It is important to study the binding characteristics of the active components in Chinese herbal medicine with plasma proteins for the medical science and modernization of TCM. This review summarizes the common analytical methods which are used to study the active herbal components-protein binding and gives the examples to illustrate their application. Rules and influence factors of the binding between different types of active herbal components and plasma proteins are summarized in the end. Finally, a suggestion on choosing the suitable technique for different types of active herbal components is provided, and the prospect of the drug-protein binding used in the area of TCM research is also discussed.

We compared a randomly assigned treatment group, who received horticultural therapy-based (HT-based) programming to a comparison group, who engaged in traditional activities (TA) programming, on engagement and affect. Horticultural therapy-based programming was implemented twice weekly at 4 treatment sites for 6 weeks, while regular TA were observed at comparison sites. Results revealed no differences between groups on affective domains. Levels of adaptive behavior differed between the groups, with the treatment group demonstrating higher levels of active, passive, and other engagement and the comparison group demonstrating higher levels of self-engagement. Our results highlight the value of HT-based programs and the importance of simultaneously capturing participants' affective and behavioral responses. Theoretical and practical considerations about the facilitation of and context in which the programming occurs are discussed.

To determine the prevalence of traditional food and physical activity use and associations with cultural factors among 3,830 Alaska Native and American Indian (AN/AI) people enrolled in the Education and Research Towards Health (EARTH) Study in 3 regions of Alaska. Cross-sectional analysis of baseline data from a cohort study. Participants (2,323 women and 1,507 men) completed a computer-assisted self-administered questionnaire that included information on diet, physical activity, life-style and cultural factors. Over 92% of participants reported eating at least 1 traditional food in the past year. The top 3 traditional foods reported were fish, moose and agutaq (a mixture of berries and fat). The percentage of people who consumed traditional foods varied by region and age but not by sex (p one traditional harvesting physical activity. Picking berries or greens, cutting/smoking fish or meat and fishing were the most common activities. Participation in traditional physical activity was highest in south-west Alaska and was higher among men than women, but did not differ by age (p speaking a Native language at home, using traditional remedies and participating in or attending traditional events (p < 0.05). The EARTH Study found relationships between traditional food use, physical activities, cultural activities and behaviours. Consumption of a variety of traditional foods and participation in traditional physical activities remain an important part of the contemporary Alaska Native life-style. Efforts to promote and sustain these foods and activities in AN/AI populations may lead to improved health outcomes.

The genus Erythrina comprises more than 100 species, widely distributed in tropical and subtropical areas. In Africa, 31 wild species and 14 cultivated species have been described. In sub-Saharan Africa, Erythrina species are used to treat frequent parasitic and microbial diseases, inflammation, cancer, wounds. The rationale of these traditional uses in African traditional medicine was established by screening several species for biological activities. Promising activities were found against bacteria, parasites (Plasmodium), human and phytopathogenic fungi, some of which were multidrug resistant (MDR) micro organisms. Some species also exhibited antioxidant, anti-inflammatory activities and enzymes inhibitory properties. Most of the species chemically investigated were reported to contain flavanones, prenylated isoflavones, isoflavanones and pterocarpans. Some phytochemicals (vogelin B, vogelin C, isowightcone, abyssinin II, derrone) were the active principles as antibacterials, antifungals, antiplasmodials and inhibitors of enzyme borne diseases (PTP1B, HIV protease, DGAT). This review highlights the important role of Erythrina species as sources of lead compounds or new class of phytotherapeutic agents for fighting against major public health (MDR infections, cancer, diabetes, obesity) in sub-Saharan Africa.

Plagiochasma appendiculatum L. & L. (Aytoniaceae), Conocephalum conicum (L.) Necker (Conocephalaceae), Bryum argenteum Hedw. (Bryaceae), and Mnium marginatum (With.) P. Beauv. (Mniaceae) are bryophytes (liverworts and mosses) used by traditional healers for the treatment of burn, cuts, wounds, and skin disorders. This study evaluated the antibacterial activity of four bryophytes against some common bacteria responsible for burn infections. Different fractions of bryophytes were screened using the disc diffusion (qualitative) and broth microdilution (quantitative) methods, according to the guidelines of the National Committee for Clinical and Laboratory Standards. Chloroform fractions of liverworts were more active against Gram negative strains while butanol fractions of mosses had significant activity against Gram positive bacteria. Staphylococcus aureus was the most sensitive strain of those tested with the butanol fraction of M. marginatum (moss), with the strongest inhibition zone of 102.92% and minimum inhibitory concentration of 30 μg mL(-1). Our findings support the use of the bryophytes in traditional medicine for burn infections because of their significant antibacterial activity.

Full Text Available This article identifies four “patterns of religion” (E P Sanders in the pseudepigraphic letters of Peter and Jude in order to support the hypothesis of a “Petrine school” (J H Elliott. The first pattern that connects the letters is a Geisttradition (K Aland, guaranteeing continuity of tradition. The second is the interrelationship between faith and ethics (fides quae and fides qua. The combination of sanctification and eschatology is a third pattern connecting the three documents. Finally, two florilegia can be identified (one from the Old Testament and apocrypha, and one from the chokmatic tradition, suggesting a fourth pattern: a warning against ungodliness and infidelity. The existence of a Petrine group could represent a preliminary stage of subsequent Early Catholicism.

The physical and social environments at schools are related to students' moderate-to-vigorous physical activity (MVPA) levels. The purpose of this study was to explore the interactive effects of the school physical environment and school social capital on the MVPA of students while at school. Data from 18,875 grade 6-10 students from 331 schools who participated in the 2009/10 Canadian Health Behaviour in School-Aged Children survey were analyzed using multi-level regression. Students answered questions on the amount of time they spend in MVPA at school and on their school's social capital. Administrator reports were used to create a physical activity related physical environment score. The school physical environment score was positively associated with student MVPA at school (β = 0.040, p < .005). The association between the school social capital and MVPA was also positive (β = 0.074, p < .001). The difference in physical environments equated to about 20 minutes/week of MVPA for students attending schools with the lowest number of physical environment features and about 40 minutes/week for students attending schools with the lowest school social capital scores by comparison to students attending schools with the highest scores. The findings suggest that school social capital may be a more important factor in increasing students MVPA than the school physical environment. The results of this study may help inform interventions aimed at increasing student physical activity levels.

Full text: Traditional reactor neutron activation analysis (NAA) based on (n, γ) - thermal neutron capture nuclear reaction has been developed into a reliable and powerful analytical method, for trace element analysis, allowing the determination of over 60 chemical elements, with good accuracy and low detection limits. Considering all possibilities of activation and a radiochemical separation of the indicator radionuclide, the majority of the elements of this group can be determined at the ppm concentration level and below. However, for solving a number of analytical problems NAA technique is not well suited or it cannot be used at all. An important limitation is that all light elements, some medium and heavy elements cannot be determined even at ppm concentration level by this method, for example, H, Be, Li, B, C, N, O, Ti, Nb, Pb, etc. Accurate determination of lithium, oxygen and other light elements in sub-microgram level is of importance in geochemical and material studies. Such examples are great many. On such instances, several non-traditional reactor activation analysis can be used which have increasingly been developed and applied to several fields of semiconductor industry, biology, geology in recent years. The purpose of this presentation is to review the modern status of non-traditional nuclear reactor activation analysis based on use of nuclear reactions excited by the flow of secondary charged particles which are produced by two methods. In first method the triton flow is produced by thermal neutrons flux which excites the nuclear reaction 6 Li(n, α)T on lithium. The neutron activation analysis associated with two consecutive reactions 6 Li(n, α)T + 16 O(T, n) 18 F is established to determine trace amounts either of lithium or of oxygen in different geological, ecological and technological samples. Besides, the triton flow can be used for the determination of other light elements, for instance, B, N, S, Mg. This nuclear reactor triton activation
Full Text Available Approximately 600-700 species of Ipomoea, Convolvulaceae, are found throughout tropical and subtropical regions of the world. Several of those species have been used as ornamental plants, food, medicines or in religious ritual. The present work reviews the traditional uses, chemistry and biological activities of Ipomoea species and illustrates the potential of the genus as a source of therapeutic agents. These species are used in different parts of the world for the treatment of several diseases, such as, diabetes, hypertension, dysentery, constipation, fatigue, arthritis, rheumatism, hydrocephaly, meningitis, kidney ailments and inflammations. Some of these species showed antimicrobial, analgesic, spasmolitic, spasmogenic, hypoglycemic, hypotensive, anticoagulant, anti-inflammatory, psychotomimetic and anticancer activities. Alkaloids, phenolics compounds and glycolipids are the most common biologically active constituents from these plant extracts.
Full Text Available Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycaemia. There are many and diverse therapeutic strategies in the management of Type 2 diabetes. The inhibition of alpha-amylase activity is only one possibility to lower postprandial blood glucose levels. In our in-vitro studies we could demonstrate that different plants, mostly traditionally used in common diabetic therapy in Africa or Europe, are able to inhibit alpha-amylase, which is responsible for the breakdown of oligosaccharides into monosaccharides which are absorbed. An inhibition of alpha-amylase activity of 90% was seen with the extract of the leaves of Tamarindus indica. To quantify inhibtion rates, acarbose was used (IC50: 23.2 µM. Highest inhibition level of acarbose in our testmodel was about 85%. Additionally tests with pure polyphenolic compounds might explain the biological activity of the selected plants.

Full Text Available By accession to the European Union (EU transition countries from Central and Eastern Europe (CEE entered a dynamic period of comprehensive change in their national societal context. Part of that changing context is the Bologna Process, by which higher education will be increasingly integrated into a unified European cross-border higher education area. Proposed harmonization of higher education structures is viewed as one of the key pillars in transforming Europe into a knowledge-driven society with more competitive businesses and higher education. In the process of dynamic transition of CEE countries university business schools are also confronted with a variety of external challenges, particularly with increased competitive pressure evolving from a globalization of knowledge production and business education which affect their future prosperity in the emerging European Higher Education Area. In the article we critically evaluate key strategic developments in a broader business education context from a perspective of their implications for the university business schools in transition countries in their effort to accomplish a proper strategic adjustment to changes in society. On the basis of comprehensive analysis of relevant institutional context, we present the conceptual framework for a strategic alignment of business schools with a changing European higher education reality.

Symplocos racemosa Roxb. belongs to a unigeneric family Symplocaceae, known as lodhra in Sanskrit; is a small evergreen tree, found throughout the tropical and sub-tropical countries. Ethnobotanical literature indicates use of S. racemosa in treatment of eye disease, skin diseases, ear diseases, liver and bowel complaints, tumors, uterine disorders, spongy and bleeding gums, asthma, fever, snake-bite, gonorrhea and arthritis. The main aim of this review is to provide detailed phytopharmacological profile on S. racemosa in support with the traditional practices and ethnomedicinal uses. All relevant worldwide accepted databases have been searched for the name "S. racemosa" along with other literature from Indian Classical texts and Pharmacopoeias. The accessible literatures available on S. racemosa, were collected through electronic search on Pub med, Scopus, Science direct and traditional reports. S. racemosa is important Indian traditional drug used in many Ayurvedic and herbal formulations for treatment of liver as well as uterine disorders and leucorrhea. Majority of phytopharmacological reports are on stem bark of the plant which include anti-cancer, hepatoprotective, anti-oxidant, anti-androgenic effect, anti-inflammatory, wound healing activity and anti-diabetic effects. Phytochemical studies indicated presence of many phenolic glycosides like symplocoside, triterpenoids like betulinic acid, acetyloleanolic acid and oleanolic acid and flavonoids like quercetin which might have contributed to the observed protective effects. Many ethnobotanical claims have been confirmed through systematic in-vitro and in-vivo pharmacological studies on different extracts of stem bark and isolated constituents. However, systematic studies on the bio-markers are desirable to establish mode of action and to validate the traditional claim in clinical practice after proper safety assessment. The conservation data of genus Symplocos showed risk of extinction due to restricted
The studies were performed on 825 school children (512 girls and 313 boys) from 1st and 2nd classes of secondary schools in som voievodship capital cities. 406 school children were from public, and 419 from non-public schools. The questionnaire prepared in the Institute for Children and Youngsters Institute in Berlin was used in this study. The evaluation of collected responses made possible to state the following conclusions: The organization of school and out school activities in public and non public schools was incorrect in several aspects ie. incorrect from the hygienic point of view organization of classes during day, too early beginning of the classes, too late ending of the classes in some week days, too long time needed to complete homework, and too late return to home after completing out school activities. The difficulties in homework completing were stated by school children from both public and non public schools. In 52% cases the parents helped in homework and 12% of children reported private lessons as an additional help in homework. The analysis of responses concerning frame of mind of school children showed better situation of pupils from non public schools. Only 15% of non public school children expressed reluctancy towards schools, as compared to 21% from public schools. The relationships between pupils and teachers did not worsened during consecutive years in non public schools, as opposite to public schools where the worsening of these relationships during the consecutive years was evident.

Chemometrics is a new branch of chemistry which is widely applied to various fields of analytical chemistry. Chemometrics can use theories and methods of mathematics, statistics, computer science and other related disciplines to optimize the chemical measurement process and maximize access to acquire chemical information and other information on material systems by analyzing chemical measurement data. In recent years, traditional Chinese medicine has attracted widespread attention. In the research of traditional Chinese medicine, it has been a key problem that how to interpret the relationship between various chemical components and its efficacy, which seriously restricts the modernization of Chinese medicine. As chemometrics brings the multivariate analysis methods into the chemical research, it has been applied as an effective research tool in the composition-activity relationship research of Chinese medicine. This article reviews the applications of chemometrics methods in the composition-activity relationship research in recent years. The applications of multivariate statistical analysis methods (such as regression analysis, correlation analysis, principal component analysis, etc. ) and artificial neural network (such as back propagation artificial neural network, radical basis function neural network, support vector machine, etc. ) are summarized, including the brief fundamental principles, the research contents and the advantages and disadvantages. Finally, the existing main problems and prospects of its future researches are proposed.
Full Text Available The present study was carried out to identify antibacterial and antioxidant characteristics of traditional aqueous extracts derived from three traditional Chinese medicinal plants (Scutellaria baicalensis, Coptis chinensis and Sonchus oleraceus. It was indicated that the S. oleraceus showed the highest antibacterial efficacy, especially against Staphylococcus aureus. The minimum inhibitory concentration (MIC of the S. oleraceus was 5.0 mg/mL what was in correlation with the high total phenolic and flavonoid contents and CUPRAC value, and MIC of both S. baicalensis and C. chinensis was 7.5 mg/mL. The rational pH of the working S. oleraceus was acidic, while the other two preferred to neutral or alkaline environment. The reasonable preservation temperature of S. baicalensis should not beyond 60°C, while the other two below 90°C. Meanwhile, S. baicalensis had significant antioxidant activity with the highest CUPRAC and ·OH scavenging activity. These results had provided useful information on further drug discovery.

In single-school studies, multiple mini-interview (MMI) and traditional interview (TI) scores are associated with acceptance offers. Unexamined is whether scores at one school are associated with acceptance at other schools; such analyses would mitigate single-school design biases and better estimate how well interviews capture desired applicant attributes. Using data from the five California Longitudinal Evaluation of Admissions Practices (CA-LEAP) public medical schools, the authors examined associations of MMI and TI scores with acceptance offers within and across schools. The analyses included applicants who interviewed at ≥1 CA-LEAP school during the 2011-2013 admissions cycles, when three CA-LEAP schools employed TIs and two employed MMIs. Interview scores were standardized (z-scores: mean = 0, SD = 1) and associations with acceptance offers were examined within and across schools in analyses stratified by school, adjusting for applicant sociodemographics, academic metrics, year, and total number of interviews. Of 4,993 applicants interviewed, 428 (8.6%) interviewed at both MMI schools, 681 (13.6%) at ≥2 TI schools, and 1,327 (26.6%) at ≥1 MMI and ≥1 TI school. For each school, acceptance was associated with interview score at that school and also with interview scores at the other four schools. Cross-school associations of MMI versus TI scores with acceptance did not differ statistically. Interview score at a given CA-LEAP school was associated with acceptance at the other four schools, with no significant differences in associations for MMIs versus TIs. The findings suggest both MMIs and TIs captured attributes valued by admissions teams across CA-LEAP schools.

Science education in the U.S. has failed for over a century to bring the experience of scientific induction to classrooms, from elementary science to undergraduate courses. The achievement of American students on international comparisons of science proficiency is unacceptable, and the disparities between groups underrepresented in STEM and others are large and resistant to reform efforts. This study investigated the enactment of a physics curriculum designed upon the inductive method in a high school serving mostly students from groups underrepresented in science. The Physics and Everyday Thinking curriculum was designed to model the central practices of science and to provide opportunities for students to both extract general principles of physics and to develop scientific models from laboratory evidence. The findings of this study suggest that scientific induction is not only a process that is well within the capacity of high school students, but they enjoy it as well. Students that engaged in the central practices of science through the inductive method reported a new sense of agency and control in their learning. These findings suggest that modeling the pedagogy of the science classroom upon the epistemology of science can result in a mode of learning that can lead to positive identification with physics and the development of scientific literacy.

Thirty-eight Tacana medicinal plant species used to treat skin problems, including leishmania ulcers, skin infections, inflammation and wound healing, were collected in the community of Buena Vista, Bolivia, with the Tacana people. Twenty two species are documented for the first time as medicinal plants for this ethnic group living in the northern area of the Department of La Paz. To evaluate the leishmanicidal effect (IC 50 ) and cytotoxicity (LD 50 ) of the selected plants. To carry out bioguided studies on the active extracts. To assess the potential of Bolivian plant biodiversity associated with traditional knowledge in the discovery of alternative sources to fight leishmaniasis. Seventy three ethanol extracts were prepared from 38 species by maceration and were evaluated in vitro against promastigotes of Leishmania amazonensis and L. braziliensis. Active extracts (IC 50 ≤ 50 μg/mL) were fractionated by chromatography on Silica gel column and the fractions were assessed against the two Leishmania strains. The most active fractions and the crude extracts were evaluated against reference strains of L. amazonensis, L. braziliensis, L. aethiopica, two native strains (L. Lainsoni and L. braziliensis) and for cytotoxicity against HeLa cells. The chromatographic profile of the active fractions was obtained by reverse phase chromatography using HPLC. From the 73 extracts, 39 extracts (53.4%) were inactive and 34 showed activity. Thirteen species were sselected for bioguided studies. The crude extracts and their 36 fractions were evaluated against two Leishmania strains. The most active fraction were tested in a panel of five leishmania strains and for cytotoxicity. The Selective Index (SI = LD 50 /IC 50 ) was calculated, and were generally low. Retention time and UV spectra were recorded for the active fractions by HPLC-DAD using a reverse phase column. Profiles were very different from each other, showing the presence of different compounds. Bolivian traditional
Full Text Available Essential oils are complex mixtures of hydrocarbons and their oxygenated derivatives arising from two different isoprenoid pathways. Essential oils are produced by glandular trichomes and other secretory structures, specialized secretory tissues mainly diffused onto the surface of plant organs, particularly flowers and leaves, thus exerting a pivotal ecological role in plant. In addition, essential oils have been used, since ancient times, in many different traditional healing systems all over the world, because of their biological activities. Many preclinical studies have documented antimicrobial, antioxidant, anti-inflammatory and anticancer activities of essential oils in a number of cell and animal models, also elucidating their mechanism of action and pharmacological targets, though the paucity of in human studies limits the potential of essential oils as effective and safe phytotherapeutic agents. More well-designed clinical trials are needed in order to ascertain the real efficacy and safety of these plant products.

Antioxidant components, including anthocyanins and phenolic compounds, antioxidant activity, and their changes during traditional cooking of fresh purple waxy corn were investigated. As compared to the raw corn, thermal treatment caused significant (p⩽0.05) decreases in each antioxidant compound and antioxidant activity. Steam cooking preserved more antioxidant compounds than boiling. Boiling caused a significant loss of anthocyanin and phenolic compounds into the cooking water. This cooking water is a valuable co-product because it is a good source of purple pigment. By comparing levels of antioxidant compounds in raw and cooked corn, we determined that degradation results in greater loss than leaching or diffusion into cooking water. Additionally, separation of kernels from the cob prior to cooking caused increased loss of antioxidant compounds. Copyright © 2014 Elsevier Ltd. All rights reserved.

To examine applicant characteristics associated with multi mini-interview (MMI) or traditional interview (TI) performance at five California public medical schools. Of the five California Longitudinal Evaluation of Admissions Practices (CA-LEAP) consortium schools, three used TIs and two used MMIs. Schools provided the following retrospective data on all 2011-2013 admissions cycle interviewees: age, gender, race/ethnicity (under-represented in medicine [UIM] or not), self-identified disadvantaged (DA) status, undergraduate GPA, Medical College Admission Test (MCAT) score, and interview score (standardized as z-score, mean = 0, SD = 1). Adjusted linear regression analyses, stratified by interview type, examined associations with interview performance. The 4,993 applicants who completed 7,516 interviews included 931 (18.6%) UIM and 962 (19.3%) DA individuals; 3,226 (64.6%) had one interview. Mean age was 24.4 (SD = 2.7); mean GPA and MCAT score were 3.72 (SD = 0.22) and 33.6 (SD = 3.7), respectively. Older age, female gender, and number of prior interviews were associated with better performance on both MMIs and TIs. Higher GPA was associated with lower MMI scores (z-score, per unit GPA = -0.26, 95% CI [-0.45, -0.06]), but unrelated to TI scores. DA applicants had higher TI scores (z-score = 0.17, 95% CI [0.07, 0.28]), but lower MMI scores (z-score = -0.18, 95% CI [-0.28, -.08]) than non-DA applicants. Neither UIM status nor MCAT score were associated with interview performance. These findings have potentially important workforce implications, particularly regarding DA applicants, and illustrate the need for other multi-institutional studies of medical school admissions processes.

The aim of this study is to isolate and identify Lactobacillus plantarum isolates from traditional cheese, Kouzeh, and evaluate their antimicrobial activity against some food pathogens. In total, 56 lactic acid bacteria were isolated by morphological and biochemical methods, 12 of which were identified as Lactobacillus plantarum by biochemical method and 11 were confirmed by molecular method. For analyzing the antimicrobial activity of these isolates properly, diffusion method was performed. The isolates were identified by 318 bp band dedicated for L. plantarum. The isolated L. plantarum represented an inhibitory activity against four of the pathogenic bacteria and showed different inhibition halos against each other. The larger halos were observed against Staphylococcus aureus and Staphylococcus epidermidis (15 ± 0.3 and 14.8 ± 0.7 mm, respectively). The inhibition halo of Escherichia coli was smaller than that of other pathogen and some L. plantarum did not show any inhibitory activity against E. coli, which were resistant to antimicrobial compounds produced by L. plantarum. The isolated L. plantarum isolates with the antimicrobial activity in this study had strong probiotic properties. These results indicated the nutritional value of Kouzeh cheese and usage of the isolated isolates as probiotic strains.

Background. Pattern differentiation is the foundation of traditional Chinese medicine (TCM) treatment for erectile dysfunction (ED). This study aims to investigate the differences in cerebral activity in ED patients with different TCM patterns. Methods. 27 psychogenic ED patients and 27 healthy subjects (HS) were enrolled in this study. Each participant underwent an fMRI scan in resting state. The fractional amplitude of low-frequency fluctuation (fALFF) was used to detect the brain activity changes in ED patients with different patterns. Results. Compared to HS, ED patients showed an increased cerebral activity in bilateral cerebellum, insula, globus pallidus, parahippocampal gyrus, orbitofrontal cortex (OFC), and middle cingulate cortex (MCC). Compared to the patients with liver-qi stagnation and spleen deficiency pattern (LSSDP), the patients with kidney-yang deficiency pattern (KDP) showed an increased activity in bilateral brainstem, cerebellum, hippocampus, and the right insula, thalamus, MCC, and a decreased activity in bilateral putamen, medial frontal gyrus, temporal pole, and the right caudate nucleus, OFC, anterior cingulate cortex, and posterior cingulate cortex (P emotion-related regions, including prefrontal cortex and cingulated cortex.

History supports the staff and single serpent, the asklepian, as the symbol of healing and medicine, yet its confusion with the caduceus (a winged staff with two snakes wrapped around it) persists. No population-based information on serpent symbol use exists. To determine the prevalence of asklepian and caduceus display among Internet images of medical and health professional schools' emblems, and to compare asklepian and caduceus display between medical and health professional schools, examining the effects of school longevity and geographic location on symbol display. This cross-sectional survey examined Internet websites and Google Images associated with medical and other health professional schools in the United States, Puerto Rico, and Canada from 2013 to 2015. The primary outcome was display of a traditional or variant asklepian or caduceus among current and past emblems in Google Images. Odds ratios (ORs) and 95% confidence intervals for the comparison of medical versus other health professional schools were calculated by logistic regression. Differences among schools' longevity were assessed with Student's t-tests and linear regression. Among images of current and past emblems of 482 schools-159 medical schools and 323 health professional schools-107 (22.2%) emblems displayed only the traditional, and 205 (42.5%) any, asklepian. Adjusting for geographic region and longevity, medical schools were 59% less likely than health professional schools to display the traditional asklepian (OR 0.41, 95% CI 0.24-0.71, P=.001), and were 7.7 times more likely than health professional schools to display the traditional caduceus. Medical schools were 8% less likely than health professional schools to display any asklepian (OR 0.92, 95% CI 0.62-1.38, P=.70), and were 3.3 times more likely than health professional schools to display any caduceus. Schools' preference of the asklepian over the caduceus confirmed historical origins. Less asklepian and more caduceus display by

Full Text Available The emergence of drug resistant variants of the influenza virus has led to a need to identify novel and effective antiviral agents. As an alternative to synthetic drugs, the consolidation of empirical knowledge with ethnopharmacological evidence of medicinal plants offers a novel platform for the development of antiviral drugs. The aim of this study was to identify plant extracts with proven activity against the influenza virus. Extracts of fifty medicinal plants, originating from the tropical rainforests of Borneo used as herbal medicines by traditional healers to treat flu-like symptoms, were tested against the H1N1 and H3N1 subtypes of the virus. In the initial phase, in vitro micro-inhibition assays along with cytotoxicity screening were performed on MDCK cells. Most plant extracts were found to be minimally cytotoxic, indicating that the compounds linked to an ethnomedical framework were relatively innocuous, and eleven crude extracts exhibited viral inhibition against both the strains. All extracts inhibited the enzymatic activity of viral neuraminidase and four extracts were also shown to act through the hemagglutination inhibition (HI pathway. Moreover, the samples that acted through both HI and neuraminidase inhibition (NI evidenced more than 90% reduction in virus adsorption and penetration, thereby indicating potent action in the early stages of viral replication. Concurrent studies involving Receptor Destroying Enzyme treatments of HI extracts indicated the presence of sialic acid-like component(s that could be responsible for hemagglutination inhibition. The manifestation of both modes of viral inhibition in a single extract suggests that there may be a synergistic effect implicating more than one active component. Overall, our results provide substantive support for the use of Borneo traditional plants as promising sources of novel anti-influenza drug candidates. Furthermore, the pathways involving inhibition of hemagglutination

Work-related musculoskeletal disorders in the neck and shoulder regions are common among carpet weavers. Working for prolonged hours in a static and awkward posture could result in an increased muscle activity and may lead to musculoskeletal disorders. Ergonomic workstation improvements can reduce muscle fatigue and the risk of musculoskeletal disorders. The aim of this study is to assess and to compare upper trapezius and middle deltoid muscle activity in 2 traditional and improved design carpet weaving workstations. These 2 workstations were simulated in a laboratory and 12 women carpet weavers worked for 3 h. Electromyography (EMG) signals were recorded during work in bilateral upper trapezius and bilateral middle deltoid. The root mean square (RMS) and median frequency (MF) values were calculated and used to assess muscle load and fatigue. Repeated measure ANOVA was performed to assess the effect of independent variables on muscular activity and fatigue. The participants were asked to report shoulder region fatigue on the Borg's Category-Ratio scale (Borg CR-10). Root mean square values in workstation A are significantly higher than in workstation B. Furthermore, EMG amplitude was higher in bilateral trapezius than in bilateral deltoid. However, muscle fatigue was not observed in any of the workstations. The results of the study revealed that muscle load in a traditional workstation was high, but fatigue was not observed. Further studies investigating other muscles involved in carpet weaving tasks are recommended. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

The aim of the study was to evaluate the in vitro antiplasmodial activity of crude extracts of 12 plant species traditionally used in Benin for the treatment of malaria in order to validate their use. For each species, dichloromethane, methanol and total aqueous extracts were tested. The antiplasmodial activity of extracts was evaluated using the measurement of the plasmodial lactate dehydrogenase activity on chloroquine-sensitive (3D7) and resistant (W2) strains of Plasmodium falciparum. The selectivity of the different extracts was evaluated using the MTT test on J774 macrophage-like murine cells and WI38 human normal fibroblasts. The best growth inhibition of both strains of Plasmodium falciparum was observed with the dichloromethane extracts of Acanthospermum hispidum DC. (Asteraceae) (IC(50)=7.5 microg/ml on 3D7 and 4.8 microg/ml on W2), Keetia leucantha (K. Krause) Bridson (syn. Plectronia leucantha Krause) (Rubiaceae) leaves and twigs (IC(50)=13.8 and 11.3 microg/ml on 3D7 and IC(50)=26.5 and 15.8 microg/ml on W2, respectively), Carpolobia lutea G.Don. (Polygalaceae) (IC(50)=19.4 microg/ml on 3D7 and 8.1 microg/ml on W2) and Strychnos spinosa Lam. (Loganiaceae) leaves (IC(50)=15.6 microg/ml on 3D7 and 8.9 microg/ml on W2). All these extracts had a low cytotoxicity. Our study gives some justifications for the traditional uses of some investigated plants.

The Colorado School of Mines (CSM) has taught its first-semester introductory physics course using a hybrid lecture/Studio Physics format for several years. Over the past year we have converted the second semester of our calculus-based introductory physics course (Physics II) to a Studio Physics format, starting from a traditional lecture-based format. In this paper, we document the early stages of this conversion in order to better understand which features succeed and which do not, and in order to develop a model for switching to Studio that keeps the time and resource investment manageable. We describe the recent history of the Physics II course and of Studio at Mines, discuss the PER-based improvements that we are implementing, and characterize our progress via several metrics, including pre/post Conceptual Survey of Electricity and Magnetism (CSEM) scores, Colorado Learning About Science Survey scores (CLASS), solicited student comments, failure rates, and exam scores.

Purpose: To improve the ability of graduate students to learn medical physics concepts through the incorporation of active learning techniques. Methods: A traditional lecture-based radiological physics course was modified such that: (1) traditional (two-hour) lectures were provided online for students to watch prior to class, (2) a student was chosen randomly at the start of each class to give a two minute synopsis of the material and its relevance (two-minute drill), (3) lectures were significantly abbreviated and remaining classroom time used for group problem solving, and (4) videos of the abbreviated lectures were made available online for review. In the transition year, students were surveyed about the perceived effects of these changes on learning. Student performance was evaluated for 3 years prior to and 4 years after modification. Results: The survey tool used a five point scale from 1=Not True to 5=Very True. While nearly all students reviewed written materials prior to class (4.3±0.9), a minority watched the lectures (2.1±1.5). A larger number watched the abbreviated lectures for further clarification (3.6±1.6) and found it helpful in learning the content (4.2±1.0). Most felt that the two-minute drill helped them get more out of the lecture (3.9±0.8) and the problem solving contributed to their understanding of the content (4.1±0.8). However, no significant improvement in exam scores resulted from the modifications (mean scores well within 1 SD during study period). Conclusion: Students felt that active learning techniques improved their ability to learn the material in what is considered the most difficult course in the program. They valued the ability to review the abbreviated class lecture more than the opportunity to watch traditional lectures prior to class. While no significant changes in student performance were observed, aptitude variations across the student cohorts make it difficult to draw conclusions about the effectiveness of active

Full Text Available Optimizing physical activity (PA in children is paramount to attenuate the incidence of chronic disease and to improve social and cognitive health. Limited research exists examining the observed PA patterns during school leisure times in children from the U.S. The purpose of this study was to examine the observed PA patterns of children during three school leisure times: before school, during lunch, and after school. The SOPLAY instrument was used to observe PA during the three leisure times across six weeks at four elementary schools in the U.S. Observer PA counts were stratified by sex, PA intensity (sedentary, walking, and very active, and leisure time. Multi-level models were employed to examine the effect of leisure time and PA intensity on observer PA counts, adjusting for day and school-level clustering. Lunch displayed the greatest number of counts for sedentary, walking, and very active PA intensities (p 0.05. After school displayed the fewest counts for walking and very active PA in both sexes (p < 0.05. An emphasis should be placed on increasing walking and very active PA intensities before school and during lunch in girls and after school in both sexes.

Arctigenin (ACT) is a phenylpropanoid dibenzylbutyrolactone lignan extracted from the traditional herb Arctium lappa L. (Compositae) with anti-viral and anti-inflammatory effects. Here, we investigated the antiviral activity of ACT found in traditional Chinese medicine on porcine circovirus type 2 (PCV2) in vitro and in vivo. Results showed that dosing of 15.6-62.5μg/mL ACT could significantly inhibit the PCV2 proliferation in PK-15 cells (P<0.01). Dosing of 62.5μg/mL ACT 0, 4 or 8h after challenge inoculation significantly inhibited the proliferation of 1MOI and 10MOI in PK-15 cells (P<0.01), and the inhibitory effect of ACT dosing 4h or 8h post-inoculation was greater than 0h after dosing (P<0.01). In vivo test with mice challenge against PCV2 infection demonstrated that intraperitoneal injection of 200μg/kg ACT significantly inhibited PCV2 proliferation in the lungs, spleens and inguinal lymph nodes, with an effect similar to ribavirin, demonstrating the effectiveness of ACT as an antiviral agent against PCV2 in vitro and in vivo. This compound, therefore, may have the potential to serve as a drug for protection of pigs against the infection of PCV2. Copyright © 2015 Elsevier Ltd. All rights reserved.

Four wild berry species, Amelanchier alnifolia, Viburnum trilobum, Prunus virginiana, and Shepherdia argentea, all integral to the traditional subsistence diet of Native American tribal communities, were evaluated to elucidate phytochemical composition and bioactive properties related to performance and human health. Biological activity was screened using a range of bioassays that assessed the potential for these little-known dietary berries to affect diabetic microvascular complications, hyperglycemia, pro-inflammatory gene expression, and metabolic syndrome symptoms. Non-polar constituents from berries, including carotenoids, were potent inhibitors of aldose reductase (an enzyme involved in the etiology of diabetic microvascular complications) whereas the polar constituents, mainly phenolic acids, anthocyanins, and proanthocyanidins, were hypoglycemic agents and strong inhibitors of IL-1β and COX-2 gene expression. Berry samples also showed the ability to modulate lipid metabolism and energy expenditure in a manner consistent with improving metabolic syndrome. The results demonstrate that these berries traditionally consumed by tribal cultures contain a rich array of phytochemicals that have the capacity to promote health and protect against chronic diseases, such as diabetes.

The purpose of this study was to investigate how students perceived their learning experience when combining traditional anatomy lectures with preparatory e-learning activities that consisted of fill-in-the-blank assignments, videos, and multiple-choice quizzes. A qualitative study was conducted to explore changes in study behaviour and perception of learning. Three group interviews with students were conducted and thematically analysed. Data was categorized into four themes: 1. Approaching the course material, 2. Understanding the material, 3. Consolidating the material, and 4. Perceived learning outcome. Students appreciated the clear structure of the course, and reported that online activities encouraged them towards a first engagement with the material. They felt that they were more active during in-class sessions, described self-study before the end-of-term exam as easier, and believed that contents would remain in their memories for a longer time. By adjusting already existing resources, lectures can be combined fairly easily and cost-effectively with preparatory e-learning activities. The creation of online components promote well-structured courses, can help minimize 'student passivity' as a characteristic element of lectures, and can support students in distributing their studies throughout the term, thus suggesting enhanced learning. Further research work should be designed to confirm the afore-mentioned findings through objective measurements of student learning outcomes.

Full Text Available The worldwide increase of multidrug resistance in both community- and health-care associated bacterial infections has impaired the current antimicrobial therapy, warranting the search for other alternatives. We aimed to find the in vitro antibacterial activity of ethanolic extracts of 16 different traditionally used medicinal plants of Nepal against 13 clinical and 2 reference bacterial species using microbroth dilution method. The evaluated plants species were found to exert a range of in vitro growth inhibitory action against the tested bacterial species, and Cynodon dactylon was found to exhibit moderate inhibitory action against 13 bacterial species including methicillin-resistant Staphylococcus aureus, imipenem-resistant Pseudomonas aeruginosa, multidrug-resistant Salmonella typhi, and S. typhimurium. The minimum inhibitory concentration (MIC values of tested ethanolic extracts were found from 31 to >25,000 μg/mL. Notably, ethanolic extracts of Cinnamomum camphora, Curculigo orchioides, and Curcuma longa exhibited the highest antibacterial activity against S. pyogenes with a MIC of 49, 49, and 195 μg/mL, respectively; whereas chloroform fraction of Cynodon dactylon exhibited best antibacterial activity against S. aureus with a MIC of 31 μg/mL. Among all, C. dactylon, C. camphora, C. orchioides, and C. longa plant extracts displayed a potential antibacterial activity of MIC < 100 μg/mL.

For decades science educators and educational institutions have been concerned with the status of science content being taught in K-12 schools and the delivery of the content. Thus, educational reformers in the United States continue to strive to solve the problem on how to best teach science for optimal success in learning. The constructivist movement has been at the forefront of this effort. With mandatory testing nationwide and an increase in science, technology, engineering, and mathematics (STEM) jobs with little workforce to fulfill these needs, the question of what to teach and how to teach science remains a concern among educators and all stakeholders. The purpose of this research was to determine if students' chemistry knowledge and interest can be increased by using the 5E learning cycle in a middle school with a high population of English language learners. The participants were eighth-grade middle school students in a large metropolitan area. Students participated in a month-long chemistry unit. The study was a quantitative, quasi-experimental design with a control group using a traditional lecture-style teaching strategy and an experimental group using the 5E learning cycle. Students completed a pre-and post-student attitude in science surveys, a pretest/posttest for each mini-unit taught and completed daily exit tickets using the Expert Science Teaching Educational Evaluation Model (ESTEEM) instrument to measure daily student outcomes in main idea, student inquiry, and relevancy. Analysis of the data showed that there was no statistical difference between the two groups overall, and all students experienced a gain in content knowledge overall. All students demonstrated a statistically significant difference in their interest in science class, activities in science class, and outside of school. Data also showed that scores in writing the main idea and writing inquiry questions about the content increased over time.

The Qassim Medical School first year curriculum includes a 5-week problem-based learning (PBL) block. Student evaluation has highlighted inadequate feedback and lack of student-student and student-tutor interactions. An online intervention may alleviate this. For each problem, a discussion forum (DF) was created with 14 threads (one for each group) in virtual PBL rooms. Students' and tutors' perceived satisfaction of the intervention was evaluated and types of posts were classified. By the end of the block, all academic staff involved and 123 students (95%) had participated in the DFs. There were around 2800 posts and 28,500 views. All 14 tutors and 102 (78%) students completed the online questionnaire. Of the students, 66 (76%) male and 36 (92%) female students responded. Overall, both students and tutors perceived the intervention positively. Posts included: reforming and finalizing learning objectives, posting the concept map constructed in the face-to-face session and questioning, encouraging and motivating each other. In addition, posts included tutors' feedback and redirection. Blending e-learning with conventional PBL may help overcome student-perceived shortcomings of conventional PBL and improve the learning experience, making learning more interactive and interesting.

Full Text Available Abstract: INTRODUCTION: Plants have been commonly used in popular medicine of most cultures for the treatment of disease. The in vitro antimicrobial activity of certain Argentine plants used in traditional medicine has been reported. The aim of this study was to investigate the antimicrobial, anti-biofilm, and anti-cell adherence activities of native plants (Larrea divaricata, Tagetes minuta, Tessaria absinthioides, Lycium chilense, and Schinus fasciculatus collected in northwestern Argentina. METHODS: The activities of the five plant species were evaluated in Bacillus strains and clinical strains of coagulase-negative Staphylococcus isolated from northwestern Argentina and identified by 16S rDNA. RESULT: Lycium chilense and Schinus fasciculatus were the most effective antimicrobial plant extracts (15.62µg/ml and 62.50µg/ml for Staphylococcus sp. Mcr1 and Bacillus sp. Mcn4, respectively. The highest (66% anti-biofilm activity against Bacillus sp. Mcn4 was observed with T. absinthioides and L. divaricate extracts. The highest (68% anti-biofilm activity against Staphylococcus sp. Mcr1 was observed with L. chilense extract. T. minuta, T. absinthioides, and L. divaricata showed percentages of anti-biofilm activity of between 55% and 62%. The anti-adherence effects of T. minuta and L. chilense observed in Bacillus sp. Mcn4 reflected a difference of only 22% and 10%, respectively, between anti-adherence and biofilm inhibition. Thus, the inhibition of biofilm could be related to cell adherence. In Staphylococcus sp. Mcr1, all plant extracts produced low anti-adherence percentages. CONCLUSION: These five species may represent a source of alternative drugs derived from plant extracts, based on ethnobotanical knowledge from northwest Argentina.

However, their antimicrobial potential has been poorly studied by modern laboratory methods. This study investigates in vitro antimicrobial activity of 49 ethanol extracts from 37 plant species used in Indonesian traditional medicine for treatment against Candida albicans, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. The plants were collected from the Biopharmaca collection garden, Bogor, Indonesia. The plant material was dried, finely grounded, extracted using ethanol, concentrated, and the dried residue was dissolved in 100% DMSO. Antimicrobial activity was determined in terms of a minimum inhibitory concentration (MIC) using a broth microdilution method in 96-well microplates. The extract of Orthosiphon aristatus (Blume) Miq. (Lamiaceae) leaf produced the strongest antimicrobial effect, inhibiting the growth of C. albicans (MIC 128 μg/mL), S. aureus (MIC 256 μg/mL), E. faecalis (MIC 256 μg/mL) and P. aeruginosa (MIC 256 μg/mL). The leaf extract of Woodfordia floribunda Salisb. (Lythraceae) also exhibited significant effect against C. albicans (MIC 128 μg/mL), S. aureus (MIC 256 μg/mL) and E. faecalis (MIC 256 μg/mL). Rotheca serrata (L.) Steane & Mabb. (Lamiaceae) leaf extract inhibited the growth of S. aureus (MIC 256 µg/mL) and C. albicans (MIC 256 µg/mL). The leaf extract of O. aristatus and W. floribunda exhibited a significant anti-candidal effect. Therefore, both of these plants can serve as prospective source materials for the development of new anti-candidal agents.

Recess and physical education time continue to diminish, creating a need for additional physical activity opportunities within the school environment. The use of school gardens as a teaching tool in elementary science and math classes has the potential to increase the proportion of time spent active throughout the school day. Teachers from 4 elementary schools agreed to teach 1 math or science lesson per week in the school garden. Student physical activity time was measured with ActiGraph GT3X accelerometers on 3 garden days and 3 no-garden days at each school. Direct observation was used to quantify the specific garden-related tasks during class. The proportion of time spent active and sedentary was compared on garden and no-garden days. Seventy-four children wore accelerometers, and 75 were observed (86% participation). Children spent a significantly larger proportion of time active on garden days than no-garden days at 3 of the 4 schools. The proportion of time spent sedentary and active differed significantly across the 4 schools. Teaching lessons in the school garden may increase children's physical activity and decrease sedentary time throughout the school day and may be a strategy to promote both health and learning.

This study monitored the physical activity behavior of adolescent students over a ten month school year. Physical activity was assessed at two month intervals using self-report and objective (Actical accelerometers) measures. Self-report results (n = 547) indicated a decline in physical activity throughout the school year for all grades and genders. The decline was attributed largely to a decrease in organized activity participation. Objective physical activity results (n = 40) revealed a significant decline in activity in the latter half of the school year (February to June). Declining physical activity was attributed to a decrease in vigorous activity which was consistent across grade and gender. Collectively, the results highlight the importance of promoting consistent opportunities for adolescents to be active throughout the school year.

The incidence of Alzheimer disease (AD) is increasing every year in accordance with the increasing of elderly population and could pose significant health problems in the future. The use of medicinal plants as an alternative prevention or even for a possible treatment of the AD is, therefore, becoming an interesting research issue. Acetylcholinesterase (AChE) inhibitors are well-known drugs commonly used in the treatment of AD. The aim of the present study was to screen for AChE inhibitory activity of the Thai traditional nootropic recipe and its herbal ingredients. The results showed that ethanolic extracts of four out of twenty-five herbs i.e. Stephania pierrei Diels. Kaempfera parviflora Wall. ex Baker, Stephania venosa (Blume) Spreng, Piper nigrum L at 0.1 mg/mL showed % AChE inhibition of 89, 64, 59, 50; the IC50 were 6, 21, 29, 30 microg/mL respectively. The other herbs as well as combination of the whole recipe had no synergistic inhibitory effect on AChE activity. However some plants revealed antioxidant activity. More research should have be performed on this local wisdom remedy to verify the uses in scientific term.

To screen for influenza virus neuraminidase inhibition and to provide a reference for the clinical treatment of influenza using traditional Chinese medicines (TCM). In this study, 421 crude extracts (solubilized with petroleum ether, ethanol, ethyl acetate, and aqueous solvents) were obtained from 113 TCM. The medicine extracts were then reacted with oseltamivir, using 2'-(4-methylumbelliferyl)-α-D-N-acetylneuraminic acid (MUNANA) as the substrate, to determine influenza virus neuraminidase activity using a standard fluorimetric assay. It was found that Chinese medicine extracts from Pyrola calliantha, Cynanchum wilfordii, Balanophora involucrata and Paeonia delavayi significantly inhibited neuraminidase activity at a concentration of 40 μg/mL. Dose-dependent inhibitory assays also revealed significant inhibition. The IC50 range of the TCM extracts for influenza virus neuraminidase was approximately 12.66-34.85 μg/mL, respectively. Some Chinese medicines have clear anti-influenza viral effects that may play an important role in the treatment of influenza through the inhibition of viral neuraminidase. The results of this study demonstrated that plant medicines can serve as a useful source of neuraminidase (NA) inhibitors and further investigation into the pharmacologic activities of these extracts is warranted.

Full Text Available Plants have an important role in maintaining people’s health and improving the quality of human life. They are an important component of people’s diet, but they are also used in other spheres of human life as a therapeutic resources, ingredients of cosmetic products, paints and others. The Daphne genus belongs to family Thymeleaceae which includes 44 families with approximately 500 herbal species. The plant species of the genus Daphne are used in the traditional medicine in China and tropical part of Africa for the treatment of various conditions. Previous studies showed significant biological potential of these species as a source of pharmacologically active compounds. This indicates that this genus possess a broad spectrum of biological activity including antimicrobial, antioxidant, analgesic, anti-inflammatory, cytotoxic, anti-ulcerogenic, abortive, hypocholesterolemic and hemostatic effects. Additionally, Daphne plants are the source of valuable bioactive phytochemicals such as coumarins, flavonoids, lignans, steroids and different classes of terpenes. Different parts of the Daphne plants contain specific bioactive metabolites and can represent a source of new, natural, pharmacologically active compounds, which may potentially be used in pharmaceutical, cosmetic and food industries.

Physical activity is important in obesity prevention, but the effectiveness of different physical activity modalities remains to be determined among children. The main purpose of this study was to compare the effects of a 6-month soccer programme and a traditional physical activity programme on changes in body composition, cardiometabolic risk factors, inflammatory and oxidative markers, cardiorespiratory fitness and perceived psychological status in obese boys. Eighty-eight boys (8-12 years; BMI > +2 standard deviations of WHO reference values) participated in one of three groups: soccer, traditional activity and control. Soccer and traditional activity programmes involved 3 sessions per week for 60-90 min at an average intensity of 70-80% of maximal heart rate. Control group participated in activities of normal daily living. All boys participated in school physical education, two sessions per week of 45-90-min. Measurements were taken at baseline and after 6 months, and included body size and composition, cardiometabolic risk factors, inflammatory and oxidative markers, cardiorespiratory fitness and perceived psychological status. Physical activity and dietary intake were assessed before and immediately following the intervention. The three groups had similar characteristics at baseline. After 6 months, both intervention groups had significantly lower relative fatness (% fat), waist circumference and total cholesterol, and higher cardiorespiratory fitness, self-esteem, perceived physical competence and attraction to physical activity compared with control group. In conclusion, physical activity interventions over 6 months positively influenced several indicators of health status among obese boys. The results also suggested that soccer has the potential as an effective tool for the prevention and reduction of childhood obesity and associated consequences.

Full Text Available Abstract Background Aegle marmelos (L. Correa has been widely used in indigenous systems of Indian medicine due to its various medicinal properties. However, despite its traditional usage as an anti-diarrhoeal there is limited information regarding its mode of action in infectious forms of diarrhoea. Hence, we evaluated the hot aqueous extract (decoction of dried unripe fruit pulp of A. marmelos for its antimicrobial activity and effect on various aspects of pathogenicity of infectious diarrhoea. Methods The decoction was assessed for its antibacterial, antigiardial and antirotaviral activities. The effect of the decoction on adherence of enteropathogenic Escherichia coli and invasion of enteroinvasive E. coli and Shigella flexneri to HEp-2 cells were assessed as a measure of its effect on colonization. The effect of the decoction on production of E. coli heat labile toxin (LT and cholera toxin (CT and their binding to ganglioside monosialic acid receptor (GM1 were assessed by GM1-enzyme linked immuno sorbent assay whereas its effect on production and action of E. coli heat stable toxin (ST was assessed by suckling mouse assay. Results The decoction showed cidal activity against Giardia and rotavirus whereas viability of none of the six bacterial strains tested was affected. It significantly reduced bacterial adherence to and invasion of HEp-2 cells. The extract also affected production of CT and binding of both LT and CT to GM1. However, it had no effect on ST. Conclusion The decoction of the unripe fruit pulp of A. marmelos, despite having limited antimicrobial activity, affected the bacterial colonization to gut epithelium and production and action of certain enterotoxins. These observations suggest the varied possible modes of action of A. marmelos in infectious forms of diarrhoea thereby validating its mention in the ancient Indian texts and continued use by local communities for the treatment of diarrhoeal diseases.
Full Text Available BACKGROUND: Active transport is a very important factor for increasing the level of physical activity in children, which is significant for both their health and positive physical behaviour in adult age. OBJECTIVE: The aim of the study was to establish the proportion of Czech children aged 11 to 15 who select active transport to and from school and, at the same time, describe socio-economic and socio-demographic factors influencing active transport to and from school among children. METHODS: To establish the socio-demographic factors affecting active transport, data of a national representative sample of 11 to 15 year-old elementary school children in the Czech Republic (n = 4,425. Research data collection was performed within an international research study called Health Behaviour in School Aged Children in June 2010. Statistical processing of the results was made using a logistic regression analysis in the statistical programme IBM SPSS v 20. RESULTS: Active transport to and from school is opted for in the Czech Republic by approximately 2/3 of children aged 11 to 15. Differences between genders are not statistically significant; most children opting for active transport are aged 11 (69%. An important factor increasing the probability of active transport as much as 16 times is whether a child's place of residence is in the same municipality as the school. Other factors influencing this choice include BMI, time spent using a computer or a privateroom in a family. A significant factor determining active transport by children is safety; safe road crossing, opportunity to leave a bicycle safely at school, no fear of being assaulted on the way or provision of school lockers where children can leave their items. CONCLUSIONS: Active transport plays an important role in increasing the overall level of physical activity in children. Promotion of active transport should focus on children who spend more time using a computer; attention should also be

We evaluated the effects of a traditional Chinese medicine (TCM), named Zeng-xiao An-shen Zhi-chan 2 (ZAZ2), on patients with Parkinson's disease (PD). Among 115 patients with idiopathic PD enrolled (mean age, 64.7 ± 10.2 years old), 110 patients (M = 65, F = 45; mean age, 64.9 ± 10.7 years old) completed the study. Patients took either ZAZ2 (n = 59) or placebo granule (n = 56) in a blind manner for 13 weeks while maintaining other anti-Parkinson medications unchanged. All participants wore a motion logger, and we analyzed the power-law temporal autocorrelation of the motion logger records taken on 3 occasions (before, one week, and 13 weeks after the drug administration). Drug efficacy was evaluated with the conventional Unified Parkinson Disease Rating Scale (UPDRS), as well as the power-law exponent α, which corresponds to the level of physical activity of the patients. ZAZ2 but not placebo granule improved the awake-sleep rhythm, the UPDRS Part II, Part II + III, and Part IV scores, and the α values. The results indicate that ZAZ2 improved activities of daily living (ADL) of parkinsonism and, thus, is a potentially suitable drug for long-term use.

Full Text Available Available studies show that environmental factors may influence how parentes choose to commute their children from home to school. Thus, the aim of this study was to analyze the association between the characteristics of the physical and social environment near school and active commuting to school among preschool children. A school-based cross-sectional study with a sample of children aged 3to 5 years (n=914 was undertaken. Participants were selected by a single-stage cluster sampling process. To obtain data on commuting to school and demographicand socioeconomic variables, a previously validated questionnaire was used while an audit tool was used to assess the environment near school. Binarylogistic regression was used to analyze the association and results were presented as Odds Ratio values. Results showed that 28.3% (95%CI 25.5-31.3 ofthe children were active commuters from home to school. A positive association was found between public transportation (p=0.002 and social environment(p=0.004 domains and active commuting. However, this association was foundonly among children from families that did not have a car. The likelihood of achild being an active commuter was higher among those who are enrolled in schools with better environmental surroundings (OR=1.88; 95%CI 1.31-2.70. It was concluded that there was a positive association between some of the environmental factors near school and active commuting to school among children from families that did not have a car.
Background:Many ancient civilizations have used plants for medicinal purposes and indeed research has suggested that plant-derived compounds can be useful for treating many ailments, including cancer and infectious diseases. One such plant, Equisetum arvense, commonly known as horsetail, is a herbal plant that grows in Saudi Arabia and is traditionally used as a diuretic. Objective (s): We sought to determine whether horsetail extract exhibits 1) cytotoxic activity on cell lines and 2) antibacterial activity on the bacterial strain Escherichia coli. Materials and Methods: Using dried aerial part of the horsetail plant, a methanolic extract was prepared for screening. This extract was examined for its cytotoxic effect on the following cell lines: cervical adenocarcinoma and breast adenocarcinoma as a cancer cell model; lung fibroblast as a normal cell model; and human embryonic kidney. After 72 hours of treatment, the cells were assayed to determine the relative percentages of dead and live cells. Microscopical examination was used to give approximate percentages and a general overview of the effect on cell morphology. The LIVE⁄DEAD® Viability⁄Cytotoxicity kit was used to determine viability of cells in the population by using two dyes: the green-fluorescent calcein-AM which stains living cells, and the red-fluorescent ethidium homodimer-1 which stains dead cells. The alamarBlue® assay, based on a fluorometric/colorimetric growth indicator that detects metabolic activity, was used to establish a relative percentage of the living cells in a population treated with the plant extract compared to untreated cells (control). To determine antibacterial activity, the disc diffusion method was used. Results: Preliminary screening suggests that the horsetail extract induces death on the four tested cell lines with the greatest effect on human embryonic kidney cells followed by breast adenocarcinoma. The extract also displayed antibacterial activity at the highest

This article explores school leadership for elementary school science teaching in an urban setting. We examine how school leaders bring resources together to enhance science instruction when there appear to be relatively few resources available for it. From our study of 13 Chicago elementary (K-8) schools' efforts to lead instructional change in mathematics, language arts, and science education, we show how resources for leading instruction are unequally distributed across subject areas. We also explore how over time leaders in one school successfully identified and activated resources for leading change in science education. The result has been a steady, although not always certain, development of science as an instructional area in the school. We argue that leading change in science education involves the identification and activation of material resources, the development of teachers' and school leaders' human capital, and the development and use of social capital.

Adolescents spend considerable time at school and thus it is important to understand their opportunities for school-based physical activity. This study surveyed Ontario secondary schools to identify the range of structured opportunities and their engagement by students. A questionnaire was mailed to key informants in 600 randomly selected secondary schools in Ontario, for which 474 respondents (79%) returned completed questionnaires. Curriculum-based physical education (PE) classes in grade nine were reported to be offered in all schools and these classes in grades 10, 11 and 12 were offered in almost all schools. Student enrollment in PE decreased from grades 9 to 12 (97.9%, 49.6%, 43.3% and 35.9%, respectively). Respondents reported that funding, timetable, facilities and resources made it somewhat difficult to implement the health and physical education curriculum in their schools. About two-thirds (65.5%) of the schools had an intramural program and 15.0% of students participated in it, whereas 97.2% of the schools had an inter-school sports program and 25.0% of students participated in it. Supervision issues made it difficult to provide intramural programs and funding made it difficult to provide inter-school sports programs. Although provision of physical activity opportunities in Ontario appears satisfactory, actual engagement by students is low. The results suggest that strategies to increase student participation in PE, intramural programs, and inter-school sports programs need further consideration.
Full Text Available Abstract Background Traditional Indian and Australian medicinal plant extracts were investigated to determine their therapeutic potential to inhibit key enzymes in carbohydrate metabolism, which has relevance to the management of hyperglycemia and type 2 diabetes. The antioxidant activities were also assessed. Methods The evaluation of enzyme inhibitory activity of seven Australian aboriginal medicinal plants and five Indian Ayurvedic plants was carried out against α-amylase and α-glucosidase. Antioxidant activity was determined by measuring (i the scavenging effect of plant extracts against 2, 2-diphenyl-1-picryl hydrazyl (DPPH and 2, 2′-azinobis-3-ethylbenzothiazoline-6-sulfonate (ABTS and (ii ferric reducing power. Total phenolic and total flavonoid contents were also determined. Results Of the twelve plant extracts evaluated, the highest inhibitory activity against both α-amylase and α-glucosidase enzymes was exerted by Santalum spicatum and Pterocarpus marsupium with IC50 values of 5.43 μg/ml and 0.9 μg/ml, respectively, and 5.16 μg/ml and 1.06 μg/ml, respectively. However, the extracts of Acacia ligulata (IC50 = 1.01 μg/ml, Beyeria leshnaultii (0.39 μg/ml, Mucuna pruriens (0.8 μg/ml and Boerhaavia diffusa (1.72 μg/ml exhibited considerable activity against α-glucosidase enzyme only. The free radical scavenging activity was found to be prominent in extracts of Acacia kempeana, Acacia ligulata followed by Euphorbia drummondii against both DPPH and ABTS. The reducing power was more pronounced in Euphorbia drummondii and Pterocarpus marsupium extracts. The phenolic and flavonoid contents ranged from 0.42 to 30.27 μg/mg equivalent of gallic acid and 0.51 to 32.94 μg/mg equivalent of quercetin, respectively, in all plant extracts. Pearson’s correlation coefficient between total flavonoids and total phenolics was 0.796. Conclusion The results obtained in this study showed that most of the plant extracts

Malaria parasites show resistance to most of the antimalarial drugs and hence developing antimalarials which can act on multitargets rather than a single target will be a promising strategy of drug design. Here we report a new approach by which virtual screening of 292 unique phytochemicals present in 72 traditionally important herbs is used for finding out inhibitors of plasmepsin-2 and falcipain-2 for antimalarial activity against P. falciparum. Initial screenings of the selected molecules by Random Forest algorithm model of Weka using the bioassay datasets AID 504850 and AID 2302 screened 120 out of the total 292 phytochemicals to be active against the targets. Toxtree scan cautioned 21 compounds to be either carcinogenic or mutagenic and were thus removed for further analysis. Out of the remaining 99 compounds, only 46 compounds offered drug-likeness as per the 'rule of five' criteria. Out of ten antimalarial drug targets, only two target proteins such as 3BPF and 3PNR of falcipain-2 and 1PFZ and 2BJU of plasmepsin-2 are selected as targets. The potential binding of the selected 46 compounds to the active sites of these four targets was analyzed using MOE software. The docked conformations and the interactions with the binding pocket residues of the target proteins were understood by 'Ligplot' analysis. It has been found that 8 compounds are dual inhibitors of falcipain-2 and plasmepsin-2, with the best binding energies. Compound 117 (6aR, 12aS)-12a-Hydroxy-9-methoxy-2,3-dimethylenedioxy-8-prenylrotenone (Usaratenoid C) present in the plant Millettia usaramensis showed maximum molecular docking score.

Wound healing is a complex cascade of events with various cellular and biochemical processes that result in reconstruction and regeneration of damaged tissue. The objective of the current study was to scientifically evaluate the medicinal plants said to produce wound healing activity in traditional Iranian medicine (TIM). Electronic databases were searched for the names of medicinal plants claimed in TIM literature for having wound healing activity. Articles were evaluated to obtain any in vitro, animal, or clinical evidence of their efficacy and possible mechanisms involved in would healing. Mechanisms of action for some of these plants, including Tamarix spp., Rosa spp., Piper betle, Plantago major, Oxalis spp., Olea europaea, Malva spp., Linum usitatissimum, and Tamarindus indica, have not been yet clarified. In contrast, some herbs such as Vitis vinifera, Quercus spp., Punica granatum, Pinus spp., Polygonum spp., Lilium spp., Gentiana lutea, Arnebia euchroma, Aloe spp., and Caesalpinia spp. have various biological and pharmacological mechanisms that have been verified for wound healing activity. Overall, TIM resources have introduced various medicinal plants for wounds with confirmed effectiveness according to current pharmacological studies. These herbal remedies could be considered as future drugs for healing of wounds. Further pharmacological and clinical investigations are recommended for exploring safety, exact mechanisms, and efficacy of these herbal remedies. .

Shifting current drug discovery tide from 'finding new drugs' to 'screening natural products' may be helpful for overcoming the 'more investment, fewer drugs' challenge. Traditional Chinese medicine (TCM), relying on natural products, has been playing a very important role in health protection and disease control for thousands of years in Asia, whose therapeutic efficacy is based on the 'synergism', that is, the combinational effects to be greater than that of the individual drug. Based on syndromes and patient characteristics and guided by the theories of TCM, formulae are designed to contain a combination of various kinds of crude drugs that, when combined, generally assume that a synergism of all ingredients will bring about the maximum of therapeutic efficacy. The increasing evidence has shown that multiple active component combinations of TCM could amplify the therapeutic efficacy of each agent, representing a new trend for modern medicine. However, the precise mechanism of synergistic action remains poorly understood. The present review highlights the concept of synergy and gives some examples of synergistic effects of TCM, and provides an overview of the recent and potential developments of advancing drug discovery towards more agile development of targeted combination therapies from TCM.

Scoparia dulcis (Sweet Broomweed) has been documented as a traditional treatment of diabetes. The administration of an aqueous extract of Scoparia dulcis at a dose of 200 mg/kg body weight significantly decreased the blood glucose with significant increase in plasma insulin level in streptozotocin diabetic rats at the end of 15 days treatment. The insulin secretagogue action of Scoparia dulcis plant extract (SPEt) was further investigated using isolated pancreatic islets from mice. SPEt at a dose of 10 microg/ml evoked 6.0 fold stimulation of insulin secretion from isolated islets indicating its insulin secretagogue activity. In addition the effect of SPEt on streptozotocin induced cell death and nitric oxide (NO) in terms of nitrite production were also examined. SPEt protected against streptozotocin- mediated cytotoxicity (88%) and NO production in rat insulinoma cell line (RINm5F). Above results suggest the glucose lowering effect of SPEt to be associated with potentiation of insulin release from pancreatic islets. Our results revealed the possible therapeutic value of Scoparia dulcis for the better control, management and prevention of diabetes mellitus progression.

Peda is an Indonesian traditional fermented whole fish prepared by addition of salt prior to fermentation and drying process. Salt used to control the growth of the lactic acid bacteria for the fermentation process. The objectives of this study were isolating and characterize the potential lactic acid bacteria (LAB) from peda as culture starter candidate, particularly its activity against pathogenic bacteria. A total of five samples from five regions of East Java Province was collected and subjected to LAB isolation. Fifty-seven of 108 colonies that show clear zone in de Man, Rogosa and Sharpe (MRS) agar supplemented with 0.5% CaCO3 were identified as LAB. Twenty-seven of the LAB isolates were exhibit inhibition against Staphylococcus aureus ATCC 6538 and Pseudomonas aeruginosa ATCC 27853. Isolate Aerococcus NJ-20 was exhibited strong inhibition against S. aureus ATCC 6538 (7.6 ± 1.35 mm inhibition zone) but was not produce bacteriocin. This finding suggests that the isolate Aerococcus NJ-20 can be applied as biopreservative culture starter on peda production. Further analysis on technological properties of isolates will be needed prior to application.

The prevalence of overweight in youth has increased three- to four-fold in the United States since the 1960s. The school environment can play prominently in the mitigation of this epidemic by increasing physical activity opportunities/ levels, decreasing the availability of food/ beverage with added sugar, and enhancing students' scientific understandings about energy balance. The potential to increase energy expenditure goes beyond the school day to include safe routes for walking and biking to school (active transport) as well as the availability of school facilities as a community resource for physical activity outside of school hours. However, school consolidation and siting decisions have profound effects on active transport as well as the school as a community resource. Teachers and adolescents should not be overlooked as important partners in conceiving and carrying out programming that seeks to increase physical activity levels in youth and the broader community. As leaders and health care providers in their communities, physicians are postured to be effective advocates of, and to leverage in their own practice, school-based policies and practices towards promoting healthy weight in youth.

Full Text Available Development of land use in public facilities such as shopping center and school gives an impact on transportation problem in Manado City, North Sulawesi. To determine factors which have causal relationship with congestion as a result of school and shopping center activity then it need to be assessed and studied. Descriptive study with observational survey was used in this study. The study ran Structural Equation Modelling (SEM by using AMOS program. Estimated method was used to calculate sample size then found 300 repondents, comprised : visitors and mall managers, school visitors, parents, school managers, Public Works department, and urban planning department .The study yielded a statistically significant correlation between school and shopping center activity with congestion s. The result indicated that school activity was positively related to congestion with p value at p=0,000 (p ≤ 0,05. Shopping center activity was positively related to congestion with p value at p=0,000 (p ≤ 0,05. The closer proximity from school to shooping center will causes severe traffic congestion. The relationship between school facility with proximity was found in p value at p=0,000 (p ≤ 0,05 . The relationship between shopping center facility with proximity was found in p value at p= 0,020 (p ≤ 0,05. While, the relationship between proximity with congestion was p= 0,008 (p ≤ 0,05. Monastery school and Mega Mall activity were affecting congestion because a closer proximity of two facilities. This indicates that the occurence of traffic congestion in Monastery School may be dependent on existence of Piere Tendean road link

This study examines effects of a school garden intervention on elementary school children's physical activity (PA). Twelve schools in New York were randomly assigned to receive the school garden intervention (n=6) or to the waitlist control group that later received gardens (n=6). PA was measured by self-report survey (Girls Health Enrichment Multi-site Study Activity Questionnaire) (N=227) and accelerometry (N=124, 8 schools) at baseline (Fall 2011) and follow-up (Spring 2012, Fall 2012, Spring 2013). Direct observation (N=117, 4 schools) was employed to compare indoor (classroom) and outdoor (garden) PA. Analysis was by general linear mixed models. Survey data indicate garden intervention children's reports of usual sedentary activity decreased from pre-garden baseline to post-garden more than the control group children's (Δ=-.19, p=.001). Accelerometry data reveal that during the school day, children in the garden intervention showed a greater increase in percent of time spent in moderate and moderate-to-vigorous PA from baseline to follow-up than the control group children (Δ=+.58, p=.010; Δ=+1.0, p=.044). Direct observation within-group comparison of children at schools with gardens revealed that children move more and sit less during an outdoor garden-based lesson than during an indoor, classroom-based lesson. School gardens show some promise to promote children's PA. clinicaltrials.gov # NCT02148315. Copyright © 2014 Elsevier Inc. All rights reserved.

Comprehensive school health (CSH) is a multifaceted approach to health promotion. A key objective of CSH is to foster positive health behaviors outside of school. This study examined the 2-year change in physical activity during and after school among students participating in a CSH intervention in Edmonton, Alberta, Canada. This was a quasi-experimental, pre-post trial with a parallel, nonequivalent control group. Intervention schools had to be located in socioeconomically disadvantaged neighborhoods. In the spring of 2009 and 2011, pedometer recordings (7 full days) and demographic data were collected from cross-sectional samples of fifth grade students from 10 intervention schools and 20 comparison schools. A total of 1157 students participated in the study. Analyses were adjusted for potential confounders and the clustered design. Relative to 2009, children in 2011 were more active on schools days (1172 steps per day; P affect children's physical activity during and outside of school. Results of this study justify broader implementation of effective CSH interventions for physical activity promotion and obesity prevention in the long term.

Full Text Available Background:An adequate level of physical activity is an important part of children's lifestyle. The school environment plays a significant role in the area of interventions and strategies aiming to increase the level of physical activity in children. Objectives: The aim of this study is to analyse foreign recommendations leading to an increased level of physical activity in children and young people in Czech schools. Methods: A systematic search of studies published between 1988 and 2012 in the English language was completed in library databases Medline, Sport Discus, ProQuest, PsychInfo, ERIC, Wiley InterScience using the following keywords: physical activity, guidelines, recommendations, school and youth. The studies were then classified based on abstract and full-text analyses. Using a content analysis the expert team formulated the final recommendations to increase the level of physical activity for schools in the Czech Republic (CR. Results: Out of the total number of 91 identified foreign studies, 25 met the predetermined criteria and were used as a basis for formulating the recommendations. These foreign studies included 15 papers published in USA, two in Australia, two in Great Britain, two in Canada, one in the European Union, one in New Zealand and one international paper (an international consensus of experts from 34 countries. Based on the interpretation of the evidence, its justification and final consensus of the expert team, the basic areas for the recommendations to increase the level of physical activity in schools in the CR were identified. Conclusions: An analysis of foreign recommendations to increase the level of physical activity designed for schools and school facilities is one of the possible methods of formulating domestic recommendations. This recommendation could contribute to deeper understanding of the issue of the deteriorating lifestyle of school-aged children in the CR and reflects the efforts for improvement.
The modern education institutes play an important role in fostering professional talents, reproducing knowledge and studies, and forming the identities of certain academic fields and vocational communities. It is a matter of common knowledge that the absence of an official Korean medicine medical school during the Japanese colonial era was a severely disadvantageous factor in the aspects of academic progress, fostering follow-up personnel, and establishment of social capability. Therefore, the then Korean medicine circle put emphasis on inadequate official education institutes as the main factor behind oppression. Furthermore, as the measure to promote the continuance of Korean medicine, the circle regarded establishing civilian Korean medicine training schools as their long-cherished wish and strived to accomplish the mission even after liberation. This study looked into how the Korean medicine circle during the Japanese colonial era utilized civilian training schools to conduct the Korean medicine education conforming to modern medical school and examined how the operation of these training schools influenced the changes in the traditional Korean medicine. After the introduction of the Western medical science, the Korean medicine circle aimed to improve the quality of Korean medicine doctors by establishing modern Korean medicine medical schools. However, after the annexation of Korea and Japan, official Korean medicine medical schools were not established since policies were organized centered on the Western medical science. In this light, the Korean medicine circle strived to nurture the younger generation of Korean medicine by establishing and operating the civilian Korean medicine training schools after the annexation between Korea and Japan. The schools were limited in terms of scale and status but possessed the forms conforming to the modern medical schools in terms of education system. In other words, the civilian training schools not only adhered to the

The traditional industrial operations are well recognized as an important source of heavy metal pollution, while that caused by the e-waste recycling activities, which have sprouted in some developing countries, is often overlooked. This study was carried out to compare the status of soil heavy metal pollution caused by the traditional industrial operations and the e-waste recycling activities in the Pearl River Delta, and assess whether greater attention should be paid to control the pollution arising from e-waste recycling activities. Both the total contents and the chemical fractionation of major heavy metals (As, Cr, Cd, Ni, Pb, Cu, and Zn) in 50 surface soil samples collected from the e-waste recycling areas and 20 soil samples from the traditional industrial zones were determined. The results show that the soils in the e-waste recycling areas were mainly polluted by Cu, Zn, As, and Cd, while Cu, Zn, As, Cd, and Pb were the major heavy metals in the soils from the traditional industrial zones. Statistical analyses consistently show that Cu, Cd, Pb, and Zn in the surface soils from both types of sites were contributed mostly by human activities, while As, Cr, and Ni in the soils were dominated by natural background. No clear distinction was found on the pollution characteristic of heavy metals in the surface soils between the e-waste recycling areas and traditional industrial zones. The potential ecological risk posed by heavy metals in the surface soils from both types of sites, which was dominated by that from Cd, ranged from low to moderate. Given the much shorter development history of e-waste recycling and its largely unregulated nature, significant efforts should be made to crack down on illegal e-waste recycling and strengthen pollution control for related activities.

The worldwide increase in the rates of childhood overweight and physical inactivity requires successful prevention and intervention programs for children. The aim of the Active Living project is to increase physical activity and decrease sedentary behavior of Dutch primary school children by developing and implementing tailored, multicomponent interventions at and around schools. In this project, school-centered interventions have been developed at 10 schools in the south of the Netherlands, using a combined top-down and bottom-up approach in which a research unit and a practice unit continuously interact. The interventions consist of a combination of physical and social interventions tailored to local needs of intervention schools. The process and short- and long-term effectiveness of the interventions will be evaluated using a quasi-experimental study design in which 10 intervention schools are matched with 10 control schools. Baseline and follow-up measurements (after 12 and 24 months) have been conducted in grades 6 and 7 and included accelerometry, GPS, and questionnaires. Primary outcome of the Active Living study is the change in physical activity levels, i.e. sedentary behavior (SB), light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), and counts-per-minute (CPM). Multilevel regression analyses will be used to assess the effectiveness of isolated and combined physical and social interventions on children's PA levels. The current intervention study is unique in its combined approach of physical and social environmental PA interventions both at school(yard)s as well as in the local neighborhood around the schools. The strength of the study lies in the quasi-experimental design including objective measurement techniques, i.e. accelerometry and GPS, combined with more subjective techniques, i.e. questionnaires, implementation logbooks, and neighborhood observations.

Full Text Available This study investigated differences in health outcomes between active and passive school commuters, and examined associations between parent perceptions of the neighborhood environment and active school commuting (ASC. One hundred-ninety-four children (107 girls, aged 9–10 years from ten primary schools in Liverpool, England, participated in this cross-sectional study. Measures of stature, body mass, waist circumference and cardiorespiratory fitness (CRF were taken. School commute mode (active/passive was self-reported and parents completed the neighborhood environment walkability scale for youth. Fifty-three percent of children commuted to school actively. Schoolchildren who lived in more deprived neighborhoods perceived by parents as being highly connected, unaesthetic and having mixed land-use were more likely to commute to school actively (p < 0.05. These children were at greatest risk of being obese and aerobically unfit(p < 0.01. Our results suggest that deprivation may explain the counterintuitive relationship between obesity, CRF and ASC in Liverpool schoolchildren. These findings encourage researchers and policy makers to be equally mindful of the social determinants of health when advocating behavioral and environmental health interventions. Further research exploring contextual factors to ASC, and examining the concurrent effect of ASC and diet on weight status by deprivation is needed.
Full Text Available Peer bullying is a phenomenon present in all schools. The school as an institution has a major role in limiting peer bullying. The primary goal of the study was to determine how different groups of students perceived school climate in relation to peer bullying regarding their role in peer bullying (active participants: bullies, victims, bully-victims and non-active participants: observers. 414 students (from 18 primary and secondary schools responded to The School Climate Bullying Survey (SCBS; Cornell, 2012, which measures the incidence of various forms of peer bullying and three dimensions of school climate (prevalence of teasing and bullying, aggressive attitudes, and willingness to seek help. The results showed that the active participants in peer bullying report a frequent presence of verbal and social bullying (54% and 40%, respectively and a significantly lower frequency of physical and cyber bullying (14%. The largest differences between the groups of students were found in their perceptions of the prevalence of aggressive attitudes and willingness to seek help in a school context. In the perceptions of both of these dimensions we found a high degree of similarity between the groups of bullies and victim-bullies, and between the groups of victims and observers. The first two groups, when compared to the victims and observers, perceived to a greater extent that school allows aggression as a way of affirmation among peers and in school in general, and that neither teachers nor peers do not stop the bullying, which discourages the victims from seeking help from them. The results confirmed the existence of the association between students’ perceived school climate by bullying and their behavior (roles in peer bullying.

Detailed knowledge about physical activity energy expenditure (PAEE) can guide the development of school interventions aimed at reducing overweight in adolescents. However, relevant components of PAEE have never been objectively quantified in this population. This study investigated the contribution of active transport to and from school, physical education (PE), and leisure time activities to total PAEE during a regular school week in adolescents. Seventy-three adolescents (mean age: 15.7 years) wore an individually calibrated combined heart rate-acceleration monitor and kept an activity diary during a regular school week. Branched equation modeling was used to calculate PAEE of the specific activity categories, and their relative contribution to total PAEE was determined. Active transport and PE contributed 30.0% and 17.4%, respectively, to school-related PAEE. Active transport to and from school contributed 15% to total PAEE. Youth with a high physical activity level (PAL) spent 4 hours less in sedentary behavior than subjects with a medium or low PAL (F = 77.415 (2.70), p activities (F = 10.583 (2.70), p Active transport and PE contribute significantly to PAEE during school hours in adolescents. To achieve an increase in total PAEE in the least active group of adolescents, promising strategies might be to reduce inactive behavior, increase participation in leisure time sports, and possibly to replace inactive for active jobs. © 2012, American School Health Association.

Physical activity (PA) is essential for human health and wellbeing across all age, socioeconomic, and ethnic groups. Engagement with the natural world is a new defining criterion for enhancing the benefits of PA, particularly for children and young people. Interacting with nature benefits children's social and emotional wellbeing, develops resilience, and reduces the risk of obesity and type 2 diabetes mellitus across all population groups. Governments around the world are now recognizing the importance of children spending more active time outdoors. However, children's outdoor activities, free play, and nature-related exploration are often structured and supervised by adults due to safety concerns and risks. In this context, schools become more accessible and safe options for children to engage in PA outdoors with the presence of nature features. Research on school designs involving young children has revealed that children prefer nature-related features in school environments. Affordances in nature may increase children's interest in physically active behaviors. Given that present school campuses are designed for operational efficiency and economic reasons, there is a need to re-design schools responding to the positive role of nature on human health. If schools were re-designed to incorporate diverse natural features, children's PA and consequent health and wellbeing would likely improve markedly.

A group comparison experiment of two high school classes with pre and post instruction testing has been carried out to study the suitability and advantages of using the active learning of optics and photonics (ALOP) curricula in high schools of developing countries. Two parallel, mixed gender, 12th grade classes of a high school run by the local university were chosen. One course was randomly selected to follow the experimental instruction, based on teacher and student activities contained in the ALOP Manual. The other course followed the traditional, teacher-centered, instruction previously practiced. Conceptual knowledge of the characteristics of image formation by plane mirrors and single convergent and divergent lenses was measured by applying, in both courses, the multiple-choice test, light and optics conceptual evaluation (LOCE). Measurement before instruction showed that initial knowledge was almost null, and therefore equivalent, in both courses. After instruction testing showed that the conceptual knowledge of students following the ALOP curricula more than doubled that achieved by students in the control course, a situation maintained throughout the six conceptual dimensions tested by the 34 questions of the LOCE test used in this experiment. Using a 60% performance level on the LOCE test as the threshold of satisfactory performance, most (about 90%) of the experimental group achieved this level—independent of initial knowledge, while no student following traditional instruction reached this level of understanding. Some considerations and recommendations for prospective users are also included.
Full Text Available Purpose : The aim of the study was to assess the level of school and out-of-school physical activity of children living in rural area at the early stage of their education. Material : The research was conducted in 2009 at primary school in Świętajno (a village. The study group consisted of 42 girls and 44 boys from the 1 st, 2 nd and 3 rd grade of primary school, aged 7-10. The children were chosen by means of a purposeful selection and surveyed by a questionnaire consisting of five open-ended and five closed-ended questions. Results : The research showed that the children living in the rural area at the early stage of their education eagerly participated in the classes of physical education held at school. The most popular physical activities among the children included: games and plays with the ball and other equipment, running, gymnastics (among girls and matches and competitions (among boys. The outdoor physical activities in which the children were involved outside of school were spontaneous and unorganized including mainly cycling, roller-skating, skating or skiing. Conclusions : A marginal percentage of children participated in out-of-school sports trainings or other physical education-oriented classes (e.g. swimming lessons. A relatively high percentage of children devoted a great deal of their free time to watching television, DVDs or playing on the computer.
Effects of traditional teaching vs a multisensory instructional package on the science achievement and attitudes of English language learners middle-school students and English-speaking middle-school students
This research was designed to determine the relative effectiveness of a Multi-sensory Instructional Package (MIP) (Dunn & Dunn, 1992) versus Traditional Teaching (TT) on the science achievement- and attitude-test scores of middle-school English Language Learner (ELL) and English-speaking sixth-, seventh-, and eighth-grade middle-school students. The dependent variables were students' science- and attitude-test scores. The independent variables were the two instructional strategies, ELL and English-speaking (Non-ELL) status, and three grade levels. The sample consisted of 282 sixth-, seventh-, and eighth-grade ELL and Non-ELL middle-school students. Learning Styles: The Clue to You! (LS: CY) (Burke & Dunn, 1998) was administered to determine learning-style preferences. The control groups were taught sixth-, seventh-, and eighth-grade science lessons traditionally and the experimental groups were instructed on the same units using MIPs. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. All three groups experienced both traditional and multi-sensory instruction in all three sub-units. The data subjected to statistical analyses supported the use of an MIP rather than a traditional approach for teaching science content to both ELLs and English-speaking middle-school students. Analysis of variance (ANOVA) revealed a positive and significant impact on achievement scores. Furthermore, the students indicated significantly more positive attitudes when instructed with an MIP approach.

The South African Department of Agriculture, Forestry and Fisheries estimated in 2012 that there were 2.033 million goats in the country. Of these animals, less than 0.5% are slaughtered at registered abattoirs. Although informal and traditional slaughter of goats for home consumption is permitted under the South African Meat Safety Act 40 of 2000, the responsibility for ensuring that products are safe is left to the traditional or ritual slaughter practitioners. The objective of the present study was to assess whether preslaughter activities associated with traditional or ritual slaughter promote or reduce food-associated risks and to recommend mitigation strategies for potential food safety hazards. Structured interviews were conducted with 105 selected respondents (in and around Tshwane, South Africa) who had been involved in traditional goat slaughter. Approximately 70% of goats slaughtered were obtained from sources that could be traced to ascertain the origin of the goats. None of the respondents were aware of the need for a health declaration for slaughter stock. Some slaughter practitioners (21%) perform prepurchase inspection of stock to ascertain their health status. However, this percentage is very small, and the approach is based on indigenous knowledge systems. The majority of respondents (67.6%) travelled 1 to 11 km to obtain a goat for traditional slaughter. Although approximately 70% of slaughter goats were transported by vehicles, the vehicles used did not meet the legal standard. More than two-thirds of goats were tied to a tree while waiting to be slaughtered, and the rest were held in a kraal. The holding period ranged from 1 to 72 h, but more than 70% of the animals were slaughtered within 36 h. This study revealed that traditional and ritual slaughter involves some preslaughter activities with potential to mitigate the risk of slaughtering animals that are not fit for human consumption. Such activities include prepurchase inspection, obtaining

In West Africa, populations are used to taking traditional medicine as a first aid against common health problems. In this aspect, many plants are claimed to be effective in the treatment of Tuberculosis (TB), which according to the World Health Organization (WHO) remains one of the world's deadliest communicable diseases. The main aim of this study was to identify plants used to treat TB-symptoms by the population of Senegal and to evaluate their possible concomitant use with clinically approved TB-drugs. This approach allowed the selection of plants effectively used in traditional medicine. In order to verify if the usage of some of these plants can be rationalized, the activity of their traditional preparations was assessed with both an intracellular and extracellular antimycobacterial host-pathogen assays. An ethnopharmacological survey conducted on 117 TB-patients and 30 healers in Senegal from March to May 2014. The questionnaires were focused on the use of medicinal plants to treat common TB -symptoms (cough longer than 2 weeks, fever, night sweats, weight loss and bloody sputum). Local plant names, utilized organs (herbal drugs) and traditional formulations of the plants were recorded. Extracts were prepared by mimicking the traditional decoction in boiling water and screened for their antimycobacterial activity using Mycobacterium marinum, as a validated TB surrogate, and an Acanthamoeba castellanii - M. marinum whole-cell based host-pathogen assay, to detect anti-infective activities. By the end of the survey, nearly 30 plants were cited and the 12 most cited herbal drugs were collected and their usage documented by extensive literature search. Extracts of the chosen herbs were screened with the described assays; with a main focus on traditional formulas (mainly herbal decoctions). Two of the water extracts from Combretum aculeatum and Guiera senegalensis showed significant antimycobacterial activities when compared to the positive control drug (rifampin

Sanguinaria canadensis, also known as bloodroot, is a traditional medicine used by Native Americans to treat a diverse range of clinical conditions. The plants rhizome contains several alkaloids that individually target multiple molecular processes. These bioactive compounds, mechanistically correlate with the plant’s history of ethnobotanical use. Despite their identification over 50 years ago, the alkaloids of S. canadensis have not been developed into successful therapeutic agents. Instead...

The present study aims to investigate the effect of two educational strategies to teach geriatrics (flipped classroom-FL and traditional lectures-TR) in relation to a control group (no intervention) on students' competences. An intervention study was conducted during the third year of medicine. Two different educational strategies (flipped classroom and traditional lectures) were incorporated into a theoretical-practical discipline of geriatrics. Students were evaluated about their attitudes towards older persons (Maxwell-Sullivan, UCLA geriatric attitudes), empathy (Maxwell-Sullivan), knowledge (Palmore and cognitive knowledge), skills (standardized patient assessment), and satisfaction with the activities. A total of 243 students were assessed. The FL group demonstrated greater gains in knowledge among students and improved attitude compared to the TR. We found no differences in the skills using a standardized patient. In addition, students exposed to FL felt more prepared to treat older people, believed they had more knowledge, were more satisfied, and evaluated the discipline's format better in relation to the traditional group. Strategies in teaching geriatrics can impact students' knowledge, attitudes, and satisfaction with the course. We found that the way this teaching is delivered can influence students' learning, since there were differences between active and traditional strategies.
The diploma is focused on social acceptance of pupils in primary school.

ABSTRACT: BACKGROUND: Walking and cycling to school provide a convenient opportunity to incorporate physical activity into an adolescent\\'s daily routine. School proximity to residential homes has been identified as an important determinant of active commuting among children. The purpose of this study is to identify if distance is a barrier to active commuting among adolescents, and if there is a criterion distance above which adolescents choose not to walk or cycle. METHODS: Data was collected in 2003-05 from a cross-sectional cohort of 15-17 yr old adolescents in 61 post primary schools in Ireland. Participants self-reported distance, mode of transport to school and barriers to active commuting. Trained researchers took physical measurements of height and weight. The relation between mode of transport, gender and population density was examined. Distance was entered into a bivariate logistic regression model to predict mode choice, controlling for gender, population density socio-economic status and school clusters. RESULTS: Of the 4013 adolescents who participated (48.1% female, mean age 16.02 +\\/- 0.661), one third walked or cycled to school. A higher proportion of males than females commuted actively (41.0 vs. 33.8%, chi2 (1) = 22.21, p < 0.001, r = -0.074). Adolescents living in more densely populated areas had greater odds of active commuting than those in the most sparsely populated areas (chi2 (df = 3) = 839.64, p < 0.001). In each density category, active commuters travelled shorter distances to school. After controlling for gender and population density, a 1-mile increase in distance decreased the odds of active commuting by 71% (chi2 (df = 1) = 2591.86, p < 0.001). The majority of walkers lived within 1.5 miles and cyclists within 2.5 miles. Over 90% of adolescents who perceived distance as a barrier to active commuting lived further than 2.5 miles from school. CONCLUSION: Distance is an important perceived barrier to active commuting and a predictor

To observe the effect of certain active components from traditional Chinese medicinal herbs on Aβ secretion rates with L-[ 35 S]-Methionine, β-amyloid peptide (Aβ) in SK-N-SH cell lines stably transfected with APP695 was metabolically labeled with L-[ 35 S]-Methionine. the supernatant from culture medium was immunoprecipitated with monoclonal antibody against Aβ 22-35 , Western blot was carried out, and the gray density of Aβ band in the autoradiograph was measured by an image analysis system. The active components from certain traditional Chinese medicinal herbs (ZMS from Zhimu and AST and HT from Huangqi) were added to the culture medium at a final concentration of 10 -5 mol/L. An Aβ band in the autoradiograph was clearly viewed in the culture medium after 24 h incorporation of [ -35 S]-Methionine which represent the secretion rate of Aβ by the cells. One of the 3 tested components (AST) could significantly reduce the Aβ secretion rate while the other two showed no effect. The preliminary result showed that certain active component from traditional Chinese medicines could decrease the Aβ secretion rate but other active components could not. Combined use of the AST and ZMS was more effective than single AST. (authors)

This study aims to explore the implementation of the Indonesian Realistic Mathematics Education (PMRI) in Aceh primary schools, Indonesia. This study investigates the students' mathematics activities involved in the implementation of PMRI and for this purpose; students' mathematics activities in the classroom were observed. Students were observed three times within five weeks during mathematics class, based on PMRI. A total of 25 year five students from a public school participated in this study. Observation check list was used in this study based on ten items. The observation conducted was based on two different time periods which were 105 minutes for group A and 70 minutes for group B. The observation was conducted every 5 minutes. The results show that PMRI is being practised in Aceh, but not completely. This study shows that mathematics activities for those who were taught using PMRI are higher than for those using the traditional approach. Overall, the findings showed that the number of student activities undertaken in PMRI achieved 90.56%. The higher percentage of activities suggests that the Aceh Education Office expands the implementation of PMRI in all primary schools so that learning of mathematics is more effective. This indirectly increases the mathematics achievement of students in Aceh to a higher level on par with Indonesia's national achievement.

Many afterschool physical activity programs and curricula are available, but evaluation of their effectiveness is needed. Well-marketed programs such as the Child and Adolescent Trial for Cardiovascular Health (CATCH) Kids Club have shown limited effectiveness in increasing physical activity for participants in comparison to control groups.…
Many companies nowadays consider schools to be an important setting for marketing to children. However, important concerns can be raised from a health promotion perspective about the potential negative impact of commercial activities on the health and well-being of pupils. As this discussion paper will demonstrate, some commercial activities raise concerns in relation to physical health and obesity, not only by potentially undermining formal curriculum messages, but also through the active promotion of specific products, particularly those high in fat, sugar or salt. Nonetheless, the issues raised by commercial activities are not solely limited to effects on physical health. By allowing commercial activities, schools risk instilling in pupils consumer-orientated values. This is significant as such values have been linked to the development of poor health and well-being. Furthermore, the presence in schools of commercial activities will also militate against informed decision-making and be disempowering. There is also evidence that business-sponsored teaching materials can contain biased and misleading information. The potential negative impacts of commercial activities are inconsistent with goals in relation to the promotion of health and the principles of health-promoting schools.

A quasi-experimental cluster-controlled design was used to test the impact of comprehensive school physical activity program (CSPAP) professional development on changes in school physical activity (PA) offerings, moderate-to-vigorous physical activity (MVPA) and sedentary behaviors of 9-14 year-old children during school. Two groups of Louisiana elementary and middle school physical education teachers (N=129) attended a CSPAP summer workshop (95 in 2012=intervention, 34 in 2013=control) and were assessed on school PA offerings (teacher-reported; pre, mid, and post). During the 2012-2013 school year, intervention teachers received CSPAP support while implementing new school PA programs. MVPA and sedentary behaviors were assessed (accelerometry; baseline and post) on a sample of 231 intervention, 120 control students from 16 different schools. Multivariate analysis of covariance indicated that intervention teachers reported significantly more PA offerings during school (3.35 vs. 2.37) and that involve staff (1.43 vs. 0.90). Three-level, mixed model regressions (stratified by sex) indicated that students overall spent less time in MVPA and more time being sedentary during school, but the effects were significantly blunted among intervention students, especially boys. This study provides preliminary evidence for CSPAP professional development programs to influence school-level PA offerings and offset student-level declines in MVPA and increases in sedentary behavior.

Full Text Available Abstract Background Worldwide particularly in developing countries, a large proportion of the population is at risk for tropical parasitic diseases. Several medicinal plants are still used traditionally against protozoal infections in Yemen and Saudi Arabia. Thus the present study investigated the in vitro antiprotozoal activity of twenty-five plants collected from the Arabian Peninsula. Methods Plant materials were extracted with methanol and screened in vitro against erythrocytic schizonts of Plasmodium falciparum, intracellular amastigotes of Leishmania infantum and Trypanosoma cruzi and free trypomastigotes of T. brucei. Cytotoxic activity was determined against MRC-5 cells to assess selectivity. The criterion for activity was an IC50 T. brucei and selectivity index of >4. Results Antiplasmodial activity was found in the extracts of Chrozophora oblongifolia, Ficus ingens, Lavandula dentata and Plectranthus barbatus. Amastigotes of T. cruzi were affected by Grewia erythraea, L. dentata, Tagetes minuta and Vernonia leopoldii. Activity against T. brucei was obtained in G. erythraea, L. dentata, P. barbatus and T. minuta. No relevant activity was found against L. infantum. High levels of cytotoxicity (MRC-5 IC50 Cupressus sempervirens, Kanahia laniflora and Kniphofia sumarae. Conclusion The results endorse that medicinal plants can be promising sources of natural products with antiprotozoal activity potential. The results support to some extent the traditional uses of some plants for the treatment of parasitic protozoal diseases.

activity, active transport and after-school fitness program. Transport mode to school was assessed through a 5-day transportation diary. Results The proportion of active transport was high at baseline (86.0%) and was maintained at the two-year follow-up (87.0%). There was no difference in active travel...... between the intervention and the comparison schools after the intervention, but more students perceived parental encouragement and had a positive attitude towards bicycling at the intervention schools. This difference was however only borderline significant. Conclusion The prevalence of AST was high...... at both baseline and follow-up, but no difference between the intervention and comparison schools was detected. Future intervention research should ensure a high degree of involvement of students, teachers and parents, focus merely on AST and take advantage of already planned physical environment changes...

[Purpose] This study aimed to compare physical activities between junior high school and high school female football players in order to explain the factors that predispose to a higher incidence of sports injuries in high school female football players. [Subjects and Methods] Twenty-nine female football players participated. Finger floor distance, the center of pressure during single limb stance with eyes open and closed, the 40-m linear sprint time, hip abduction and extension muscle strength and isokinetic knee flexion and extension peak torque were measured. The modified Star Excursion Balance Test, the three-steps bounding test and three-steps hopping tests, agility test 1 (Step 50), agility test 2 (Forward run), curl-up test for 30 seconds and the Yo-Yo intermittent recovery test were performed. [Results] The high school group was only significantly faster than the junior high school group in the 40-m linear sprint time and in the agility tests. The distance of the bounding test in the high school group was longer than that in the junior high school group. [Conclusion] Agility and speed increase with growth; however, muscle strength and balance do not develop alongside. This unbalanced development may cause a higher incidence of sports injuries in high school football players.

To analyze physical activity and sedentary behavior in preschool children during their stay at school and the associated factors. 370 preschoolers, aged 4 to 6 years, stratified according to gender, age and school region in the city of Londrina, PR, participated in the study. A questionnaire was applied to principals of preschools to analyze the school infrastructure and environment. Physical activity and sedentary behavior were estimated using accelerometers for five consecutive days during the children's stay at school. The odds ratio (OR) was estimated through binary logistic regression. At school, regardless of age, preschoolers spend relatively more time in sedentary behaviors (89.6%-90.9%), followed by light (4.6%-7.6%), moderate (1.3%-3.0%) and vigorous (0.5%-2.3%) physical activity. The indoor recreation room (OR=0.20; 95%CI 0.05 to 0.83) and the playground (OR=0.08; 95%CI 0.00 to 0.80) protect four-year-old schoolchildren from highly sedentary behavior. An inverse association was found between the indoor recreation room and physical activity (OR=0.20; 95%CI 0.00 to 0.93) in five-year-old children. The indoor recreation room (OR=1.54; 95%CI 1.35 to 1.77), the playground (OR=2.82; 95%CI 1.14 to 6.96) and the recess (OR=1.54; 95%CI 1.35 to 1.77) are factors that increase the chance of six-year-old schoolchildren to be active. The school infrastructure and environment should be seen as strategies to promote physical activity and reduce sedentary behavior in preschool children.

Our study is the first to describe the prevalence and correlates (demographics, body mass index [BMI], sedentary behaviors, and physical activity) of high school youth who report active videogame playing (active gaming) in a U.S. representative sample. The National Youth Physical Activity and Nutrition Study of 2010 provided data for this study. Active gaming was assessed as the number of days in the 7 days prior to the survey that students in grades 9-12 (14-18 years of age) reported participating in active videogames (e.g., "Wii™ Fit" [Nintendo, Kyoto, Japan], "Dance Dance Revolution" [Konami, Osaka, Japan]). Students reporting ≥1 days were classified as active gamers. Logistic regression was used to examine the association among active gaming and demographic characteristics, BMI, sedentary behaviors, and physical activity. Among 9125 U.S. high school students in grades 9-12 surveyed, 39.9 percent (95 percent confidence interval=37.9 percent, 42.0 percent) reported active gaming. Adjusting for covariates, the following characteristics were positively associated (Pblack, non-Hispanic race/ethnicity; being overweight or obese; watching DVDs >0 hours/day; watching TV >0 hours/day; and meeting guidelines for aerobic and muscle-strengthening physical activity. Four out of 10 U.S. high school students report participating in active gaming. Active gamers tend to spend more time watching DVDs or TV, meet guidelines for physical activity, and/or be overweight or obese compared with nonactive gamers. These findings may serve to provide a baseline to track active gaming in U.S. youth and inform interventions that target sedentary behaviors and/or physical activity.

Interscholastic, intramural, and club physical activity (PA) programs can be important contributors to student PA accrual at schools. Few studies have assessed factors related to the provision of these extracurricular PA programs, especially in private schools. We used a 16-item questionnaire to assess the associations and influences of selected factors relative to extracurricular PA program policies and practices in 450 private California secondary schools. Associations were evaluated using contingency table analyses (i.e., chi-squared, effect size, and post-hoc analyses). Six factors were associated with schools providing extracurricular PA programs: school location, level, enrollment, and religious classification and whether the physical education (PE) program met state PE time standards and was taught by PE specialists. Both static factors (e.g., school location, level, enrollment, and religious affiliation) and modifiable factors (e.g., meeting PE standards and employing specialists) affect the provision of extracurricular PA programs. As education is state-mandated, additional study is recommended to assess the generalizability of these findings to other states and to public schools.

The intern year is a critical time for making career decisions and gaining confidence in clinical skills, communication and teamwork practices; this justifies an interest in junior doctors' perceptions of their level of preparedness for hospital work. This study explored Australian junior doctors' perspectives regarding the transition from student to doctor roles, their preparation as medical undergraduates within either traditional metropolitan schools or smaller, outer metropolitan-based (rural) programs such as Rural Clinical Schools (RCS), and the educational environment they experienced in their internship. A qualitative cross-sectional design used semi-structured interviews with postgraduate year one and two junior doctors (9 females and 11 males) within teaching hospitals in Queensland Australia. Interview questions focussed on four major content areas: preparedness for hospital work, undergraduate training, building confidence and career advice. Data were analyzed using a framework method to identify and explore major themes. Junior doctors who spent undergraduate years training at smaller, non-traditional medical schools felt more confident and better prepared at internship. More hands-on experience as students, more patient contact and a better grounding in basic sciences were felt by interns to be ideal for building confidence. Junior doctors perceived a general lack of career guidance in both undergraduate and postgraduate teaching environments to help them with the transition from the student to junior doctor roles. Findings are congruent with studies that have confirmed student opinion on the higher quality of undergraduate medical training outside a traditional metropolitan-based program, such as a RCS. The serious shortage of doctors in rural and remote Australia makes these findings particularly relevant. It will be important to gain a better understanding of how smaller non-traditional medical programs build confidence and feelings of work

To examine factors associated with regular physical activity in Croatian adolescents. A cross-sectional survey among high school students was carried out in the 2013/14 school year. A survey was conducted among 33 high schools in Zagreb City, Croatia. Participants were students aged 17-18 years. The dependent variables were regular moderate to vigorous physical activity (MVPA) and overall physical activity measured by the short version of International Physical Activity Questionnaire and defined as 60 min or more of daily physical activity. The independent variables included family, neighborhood, and high school social capital. Other study covariates included: socio-economic status, self-rated health, psychological distress and nutritional status. The associations between physical activity and social capital variables were assessed separately for boys and girls through multiple logistic regression and inverse probability weighting in order to correct for missing data bias. A total of 1689 boys and 1739 girls responded to the survey. A higher percentage of boys reported performing regular vigorous and moderate physical activity (59.4%) and overall physical activity (83.4%), comparing with the girls (35.4% and 70%, respectively). For boys, high family social capital and high informal social control were associated with increased odds of regular MVPA (1.49, 95%CI: 1.18 - 1.90 and 1.26, 95%CI: 1.02 - 1.56, respectively), compared to those with low social capital. For girls, high informal social control was associated with regular overall physical activity (OR 1.38, 95% CI: 1.09 - 1.76). High social capital is associated with regular MVPA in boys and regular overall activity in girls. Intervention and policies that leverage community social capital might serve as an avenue for promotion of physical activity in youth. Copyright © 2016 The Royal Society for Public Health.

The societal demand for inspiring and engaging science, technology, engineering, and mathematics (STEM) students and preparing our workforce for the emerging creative economy has necessitated developing students' self-efficacy and understanding of engineering design processes from as early as elementary school levels. Hands-on engineering design activities have shown the potential to promote middle school students' self-efficacy and understanding of engineering design processes. However, traditional classrooms often lack hands-on engineering design experiences, leaving students unprepared to solve real-world design problems. In this study, we introduce the framework of a toy design workshop and investigate the influence of the workshop activities on students' understanding of and self-efficacy beliefs in engineering design. Using a mixed method approach, we conducted quantitative analyses to show changes in students' engineering design self-efficacy and qualitative analyses to identify students' understanding of the engineering design processes. Findings show that among the 24 participants, there is a significant increase in students' self-efficacy beliefs after attending the workshop. We also identified major themes such as design goals and prototyping in students' understanding of engineering design processes. This research provides insights into the key elements of middle school students' engineering design learning and the benefits of engaging middle school students in hands-on toy design workshops.

Drugs are exogenous compounds for human bodies, and will be metabolized by many enzymes after administration. CYP450 enzyme, as a major metabolic enzyme, is an important phase I drug metabolizing enzyme. In human bodies, about 75% of drug metabolism is conducted by CYP450 enzymes, and CYP450 enzymes is the key factor for drug interactions between traditional Chinese medicine( TCM) -TCM, TCM-medicine and other drug combination. In order to make clear the interaction between metabolic enzymes and TCM metabolism, we generally chose the enzymatic activity as an evaluation index. That is to say, the enhancement or reduction of CYP450 enzyme activity was used to infer the inducing or inhibitory effect of active ingredients and extracts of traditional Chinese medicine on enzymes. At present, the common method for measuring metabolic enzyme activity is Cocktail probe drugs, and it is the key to select the suitable probe substrates. This is of great significance for study drug's absorption, distribution, metabolism and excretion (ADME) process in organisms. The study focuses on the interaction between TCMs, active ingredients, herbal extracts, cocktail probe substrates as well as CYP450 enzymes, in order to guide future studies.
Full Text Available Sanguinaria canadensis, also known as bloodroot, is a traditional medicine used by Native Americans to treat a diverse range of clinical conditions. The plants rhizome contains several alkaloids that individually target multiple molecular processes. These bioactive compounds, mechanistically correlate with the plant’s history of ethnobotanical use. Despite their identification over 50 years ago, the alkaloids of S. canadensis have not been developed into successful therapeutic agents. Instead, they have been associated with clinical toxicities ranging from mouthwash induced leukoplakia to cancer salve necrosis and treatment failure. This review explores the historical use of S. canadensis, the molecular actions of the benzophenanthridine and protopin alkaloids it contains, and explores natural alkaloid variation as a possible rationale for the inconsistent efficacy and toxicities encountered by S. canadensis therapies. Current veterinary and medicinal uses of the plant are studied with an assessment of obstacles to the pharmaceutical development of S. canadensis alkaloid based therapeutics.

This review explores the historical use of S. canadensis, the molecular actions of the benzophenanthridine and protopin alkaloids it contains, and explores natural alkaloid variation as a possible rationale for the inconsistent efficacy and toxicities encountered by S. canadensis therapies. Current veterinary and medicinal uses of the plant are studied with an assessment of obstacles to the pharmaceutical development of S. canadensis alkaloid based therapeutics.

Many educational researchers have proposed teaching statistics with less lecture and more active learning methods. However, there are only a few comparative studies that have taught one section of statistics with lectures and one section with activity-based methods; of those studies, the results are contradictory. To address the need for more research on the actual effectiveness of active learning methods in introductory statistics, this research study was undertaken. An introductory, univ...

This study evaluates the radical-scavenging activity of five plants used as food and medicines in the northeastern region of Brazil. Spectrophotometric analysis of the plants' ethanol extracts was carried out. The antioxidant activity was determined by the DPPH (2,2-diphenyl-1 picrylhydrazyl) test. The antioxidant capacity was measured using ascorbic acid as a positive control. All tested plant extracts showed an antioxidant activity, but the highest activity was observed with the extracts of Momordica charantia and Eugenia jambolana. Therefore, these species must be studied as a putative source of products for use in the prevention and treatment of diseases in which oxidants or free radicals are implicated.

Full Text Available Universidade Júnior is a very large educational program for the promotion of knowledge among pre-university children and teenagers launched in 2005 by U.Porto. This extremely popular initiative is currently attracting around 5000 students per year for a variety of learning activities and small research projects offered by the 14 Faculties of U.Porto during July and September. Besides providing a foretaste of university life and vocational orientation, they also give the youngsters a strong incentive to continue their studies into higher education and a knowledge-based career. A key element to the success of this process is the mentoring activity that is developed at two levels: between faculty and the junior tutors and between these and the young students.

Full Text Available Regarding school curricula as social constructions, in this paper we analyze the building up of a tradition, which goes back to the 1960s, related to the introduction of Algebra in elementary school. This tradition is presented as an inheritance of the modern mathematics movement and it is argued that the analysis of curricular innovation processes should not take into account only their proclaimed purposes, but should consider broader effects related to the breakdown of older traditions. Keywords: History of Mathematics Education. Curriculum. Modern Mathematics. Teaching of Algebra.Na linha dos estudos que investigam os currículos escolares como construções sociais, este artigo examina a constituição de uma tradição relativa à iniciação em Álgebra na escola, cuja origem remonta aos anos 1960. Ao apresentar essa tradição como uma herança do movimento da matemática moderna, argumenta que os processos de inovação curricular não devem ser analisados apenas no confronto com suas intenções anunciadas, mas pelos efeitos mais amplos que produzem de desconstituição das tradições mais antigas.

Full Text Available Differences in recess physical activity (PA according to perceived school environment among elementary school children were examined. Participants were 103 children from two schools in Japan. PA was measured using accelerometry for seven consecutive days. Time spent in sedentary or PA (light, moderate, or vigorous during their morning recess (25 min and lunch recess (15 min was determined. The School Physical Activity Environment Scale (three factors: equipment, facility, and safety was used to investigate perceived school environment. Environmental factor scores were assigned to low or high groups for each factor by median. An analysis of covariance, with grade as the covariate, was conducted separately by gender to examine differences in PA between two groups. During lunch recess, boys in the high-equipment group spent significantly more time in moderate PA (high: 1.5; low: 0.8 min whereas girls in this group spent less time in light PA (9.3, 11.0. Boys in the high-facility group spent significantly less time in sedentary (2.3, 3.9 and more time in vigorous PA (2.4, 1.4 during lunch recess, and girls spent more time in moderate (2.1, 1.2 and vigorous PA (1.9, 1.3 during morning recess. Differences were observed in recess PA according to school environment perceptions. The present study may be useful for further intervention studies for the promotion of PA during recess.

The leaves of Toddalia asiatica (L.) Lam. (Rutaceae) are widely used in folk medicine in India to treat various ailments like cough, malaria, indigestion, influenza lung diseases and rheumatism, fever, stomach ailments, cholera and diarrhea. In our earlier communication we have reported the antimicrobial study on the various extracts of the leaves and the isolation and identification of Flindersine, a quinolone alkaloid as the major active principle. In the present study, we report the antibacterial and antifungal activities of Ulopterol, a coumarin isolated as another major active antimicrobial principle. The leaves were successively extracted with hexane, chloroform, ethyl acetate, methanol and water. The extracts were studied for their antimicrobial activity against selected bacteria and fungi by using disc-diffusion method. The ethyl acetate extract which was found to possess highest antimicrobial activity was subjected to activity guided fractionation by column chromatography over silica gel. This resulted in the isolation of the coumarin, Ulopetrol, an active principle besides Flindersine which was reported by us earlier. The structure of the compound was elucidated using physical and spectroscopic data. Flindersine and Ulopterol were quantified by HPLC. Ulopterol showed activity against the bacteria viz. Staphylococcus epidermidis, Enterobacter aerogenes, Shigella flexneri, Klebsiella pneumoniae (ESBL-3967), Escherichia coli (ESBL-3984) and fungi viz. Aspergillus flavus, Candida krusei and Botrytis cinerea. Quantification by HPLC showed the content of Flindersine and Ulopterol to be 0.361% and 0.266% respectively on dry weight basis of the leaves. Ethyl acetate extract (successive extraction) contained Ulopterol, a coumarin, besides Flindersine, a quinolone alkaloid, as a major active principle in the antimicrobial studies. This is the first report of the antimicrobial activity of Ulopterol and also its first report from the plant. Copyright Â© 2012

PURPOSE. This study compares a traditional worksite-based health promotion program with an activated consumer program and a control program DESIGN. Group randomized controlled trial with 18-month intervention. SETTING. Two large Midwestern companies. SUBJECTS. Three hundred and twenty employees (51% response). INTERVENTION. The traditional health promotion intervention offered population-level campaigns on physical activity, nutrition, and stress management. The activated consumer intervention included population-level campaigns for evaluating health information, choosing a health benefits plan, and understanding the risks of not taking medications as prescribed. The personal development intervention (control group) offered information on hobbies. The interventions also offered individual-level coaching for high risk individuals in both active intervention groups. MEASURES. Health risk status, general health status, consumer activation, productivity, and the ability to evaluate health information. ANALYSIS. Multivariate analyses controlled for baseline differences among the study groups. RESULTS. At the population level, compared with baseline performance, the traditional health promotion intervention improved health risk status, consumer activation, and the ability to recognize reliable health websites. Compared with baseline performance, the activated consumer intervention improved consumer activation, productivity, and the ability to recognize reliable health websites. At the population level, however, only the activated consumer intervention improved any outcome more than the control group did; that outcome was consumer activation. At the individual level for high risk individuals, both traditional health coaching and activated consumer coaching positively affected health risk status and consumer activation. In addition, both coaching interventions improved participant ability to recognize a reliable health website. Consumer activation coaching also

Medicinal plants involved in traditional Thai longevity formulations are potential sources of antimicrobial compounds. To evaluate the antimicrobial activities of some extracts from medicinal plants used in traditional Thai longevity formulations against some oral pathogens, including Streptococcus pyogenes, Streptococcus mitis, Streptococcus mutans, and Candida albicans. An extract that possessed the strongest antimicrobial activity was fractionated to isolate and identify the active compounds. Methanol and ethyl acetate extracts of 25 medicinal plants used as Thai longevity formulations were evaluated for their antimicrobial activity using disc diffusion (5 mg/disc) and broth microdilution (1.2-2500 µg/mL) methods. The ethyl acetate extract of Ficus foveolata Wall. (Moraceae) stems that exhibited the strongest antibacterial activity was fractionated to isolate the active compounds by an antibacterial assay-guided isolation process. The ethyl acetate extract of F. foveolata showed the strongest antibacterial activity with minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of 19.5-39.0 and 39.0-156.2 µg/mL, respectively. On the basis of an antibacterial assay-guided isolation, seven antibacterial compounds, including 2,6-dimethoxy-1,4-benzoquinone (1), syringaldehyde (2), sinapaldehyde (3), coniferaldehyde (4), 3β-hydroxystigmast-5-en-7-one (5), umbelliferone (6), and scopoletin (7), were purified. Among these isolated compounds, 2,6-dimethoxy-1,4-benzoquinone (1) exhibited the strongest antibacterial activities against S. pyogenes, S. mitis, and S. mutans with MIC values of 7.8, 7.8, and 15.6 µg/mL, and MBC values of 7.8, 7.8, and 31.2 µg/mL, respectively. In addition, this is the first report of these antibacterial compounds in the stems of F. foveolata.

Little is known about physical activity (PA) among children with intellectual disability (ID) or their reasons to take part in PA and sport. To investigate PA and PA patterns during school and after school among Icelandic children with mild-to-severe ID. Ninety-one children with ID and a matched group of 93 typically developed individuals (TDI) took part. PA was assessed with accelerometers and a questionnaire was used to collect data on PA behavior. TDI children were more active and less sedentary than children with ID (p<0.001). Both sexes with ID were more active and less sedentary during school than after school (p<0.003) but no difference was found among TDI children. Children with ID (60%) were more likely to name weight loss as a reason to participate in PA than TDI children (34%, p=0.002) but a higher proportion (96%) of TDI children than children with ID (50%) participated in PA to improve skills (p<0.001). Children with ID depend more on schools to accumulate their PA and their reasons for PA participation differ from TDI children. This needs to be considered when designing and implementing PA promotion campaigns for children with ID. Copyright © 2016 Elsevier Ltd. All rights reserved.

During a 15-month period between February 2010 and April 2011, video data on (n = 38) people with dementia were collected during a person-centered and intergenerational arts activity program called Opening Minds through Art (OMA) at three different long-term care facilities in Ohio. A subsample of the OMA participants (n = 10) were also video recorded during traditional visual arts activities (e.g. coloring books, scrapbooking). A modified version of the Greater Cincinnati Chapter Well-Being Observation Tool© was used to code the intensity and frequency of observed domains of well-being (i.e. social interest, engagement, and pleasure) and ill-being (i.e. disengagement, negative affect, sadness, and confusion). Descriptive results indicate a high percentage of moderate or high intensities of well-being during OMA sessions with little to no ill-being. Paired-sample t-tests comparing OMA vs. traditional visual arts activities showed significantly higher intensity scores for OMA in the domain of engagement and pleasure, as well as significantly lower intensity scores for disengagement. The findings of this exploratory study contribute to the overall discussion about the impact of person-centered, creative-expressive arts activities on people with dementia. © The Author(s) 2014.

Urton, all belonging to the Vitaceae family, were evaluated to determine their therapeutic potentials as antineoplastic agents. The antiproliferative activity in vitro against HepG2 cells was determined. Twenty-two of the twenty-seven crude plant extracts showed activities ranging from 25% to 97% inhibition of proliferation when compared with the control which showed no inhibitory activity. Higher degrees of growth inhibition were found in aqueous root extracts in comparison with the methanol extracts of the same plant parts. The results show potential antineoplastic activity, indicating some scientific validation for traditional usage. Copyright 2000 John Wiley & Sons, Ltd.

A comparison of students who chose a traditional or a problem-based learning curriculum after failing year 2 in the traditional curriculum: a unique case study at the Nelson R. Mandela School of Medicine.
To canvas perceptions and experiences of students who had failed Year 2 of a traditional medical program and who chose to remain in the conventional program (n = 6) or had swapped to Curriculum 2001 (C2001), a problem-based learning (PBL) curriculum (n = 14). A year after their decision regarding curriculum choice, students were canvassed (largely open-ended survey) about this decision and about their perceptions of their curricular experiences. C2001 students were positive about their PBL experiences. Overwhelmingly, their decision to swap streams had been a good one. They identified PBL features as supporting their learning. Repeating traditional curriculum students were, however, more circumspect in their opinions. C2001 students had clearly embraced PBL. They were now medical students, largely because of PBL activities underpinned by a sound educational philosophy. This unique case study has provided additional evidence that PBL students are generally more content with their studies than their conventional curriculum counterparts.

Full Text Available Background: Many natural products from plants have been recognized to exert anticancer activity. In this study, ethanolic extracts of selected medicinal herbs from Iranian flora including Alyssum homolocarpum Fisch. (from seeds, Urtica dioica L. (from aerial parts, Cichorium intybus L. (from roots and Solanum nigrum L. (from fruits, were evaluated for their cytotoxic effect on different cell lines.Methods: Cytotoxic effect of these extracts was studied on three different cancer cell lines; colon carcinoma (HT-29, colorectal adenocarcinoma (Caco-2 and breast ductal carcinoma (T47D. In addition, Swiss mouse embryo fibroblasts (NIH 3T3 were used as normal nonmalignant cells. MTT assay (3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide was utilized for calculating the cytotoxicity of extracts on cell lines.Results: Results showed the potent cytotoxic activity of U. dioica ethanolic extract against T47D cell line with IC50 value of 46.14±4.55 µg/ml. Other extracts showed poor activity with IC50>100 µg/ml.Conclusions: Cytotoxic activity recorded in the present study revealed high potential antiproliferative activity of U. dioica ethanolic extract against T47D cell line. The real IC50 values of this extract may be considerably lower than the IC50 measured in our study if its pharmacological active compounds become pure. The results emphasize the importance of studies on U. dioica ethanolic extract to characterize potential components as cytotoxic natural medicines.
Full Text Available The aim of this research was to identify the volatile metabolites produced in different organs (leaves, stem and roots of Polygonum minus, an important essential oil producing crop in Malaysia. Two methods of extraction have been applied: Solid Phase Microextraction (SPME and hydrodistillation coupled with Gas Chromatography-Mass Spectrometry (GC-MS. Approximately, 77 metabolites have been identified and aliphatic compounds contribute significantly towards the aroma and flavour of this plant. Two main aliphatic compounds: decanal and dodecanal were found to be the major contributor. Terpenoid metabolites were identified abundantly in leaves but not in the stem and root of this plant. Further studies on antioxidant, total phenolic content, anticholinesterase and antimicrobial activities were determined in the essential oil and five different extracts. The plant showed the highest DPPH radical scavenging activity in polar (ethanol extract for all the tissues tested. For anti-acetylcholinesterase activity, leaf in aqueous extract and methanol extract showed the best acetylcholinesterase inhibitory activities. However, in microbial activity, the non-polar extracts (n-hexane showed high antimicrobial activity against Methicillin-resistant Staphylococcus aureus (MRSA compared to polar extracts. This study could provide the first step in the phytochemical profiles of volatile compounds and explore the additional value of pharmacology properties of this essential oil producing crop Polygonum minus.

Full Text Available Culture is a form of creative expression of a human being through which he reshapes the world, acts on it adding it value and creating new, cultural values. A human being is able to create a product of culture only when he is free and able to express himself. A contemporary man can incorporate various cultural activities into his spare time. They are especially important when they concern children and young people: regardless of whether they are used in institutional settings or in spare time. The authors conducted an empirical research of students' assumptions and beliefs concerning cultural activities in their free time. The sample comprised 233 fifth grade students. The findings show that in their spare time fifth graders: engage in various cultural activities; that students who live in urban areas attend more cultural events; that students have the opportunity to engage in extra-curricular activities in the area of culture - join cultural and artistic groups and associations and engage in various creative pursuits at different levels of participation (as consumers, full participants; and that students' attitudes concerning the influence of parents and teachers on the selection of cultural activities to be pursued do not vary greatly by gender, location or school achievement. Cultural activities do play a significant part in the free time of primary school students. This is why it is important that guidance provided in school and in spare time should be brought in greaer harmony.

The Medical School of the Federal University of Rio Grande do Norte (UFRN) is one of the biggest public medical schools in Northeast Brazil. In the last decade, significant investment in faculty development, innovative learning methodologies and student engagement has been key milestones in educational improvement at this medical school, harnessed to recent political changes that strengthened community-based and emergency education. This study describes how curriculum changes in UFRN Medical School have been responsible for major improvements in medical education locally and which impacts such transformations may have on the educational community. A group of students and teachers revised the new curriculum and established the key changes over the past years that have been responsible for the local enhancement of medical education. This information was compared and contrasted to further educational evidences in order to define patterns that can be reproduced in other institutions. Improvements in faculty development have been fairly observed in the institution, exemplified by the participation of a growing number of faculty members in programs for professional development and also by the creation of a local masters degree in health education. Alongside, strong student engagement in curriculum matters enhanced the teaching-learning process. Due to a deeper involvement of students and teachers in medical education, it has been possible to implement innovative teaching-learning and assessment strategies over the last ten years and place UFRN Medical School at a privileged position in relation to undergraduate training, educational research and professional development of faculty staff.

Ethanolic extracts of eight medicinal plants commonly used in folk medicine were tested for their antibacterial activity against four Gram positive strains (Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermidis and, Streptococcus pneumoniae) and six Gram negative strains (Escherichia coli, Proteus vulgaris, Proteus mirabilis. Salmonella typhi para A, Salmonella typhi para B and Shigella dysenteriae) that were obtained from different pathological laboratories located in Karachi, Pakistan. Disc diffusion method was used to analyze antibacterial activity. Out of eight, five medicinal plants showed antibacterial activity against two or more than two microbial species. The most effective antimicrobial plant found to be Punica granatum followed by Curcuma zedoaria Rosc, Grewia asiatica L and Carissa carandas L, Curcuma caesia Roxb respectively. From these results, it is evident that medicinal plants could be used as a potential source of new antibacterial agents.

Pereskia bleo, a leafy cactus, is a medicinal plant native to West and South America and distributed in tropical and subtropical areas. It is traditionally used as a dietary vegetable, barrier hedge, water purifier, and insect repellant and for maintaining health, detoxification, prevention of cancer, and/or treatment of cancer, hypertension, diabetes, stomach ache, muscle pain, and inflammatory diseases such as dermatitis and rheumatism. The aim of this paper was to provide an up-to-date and comprehensive review of the botanical characteristics, traditional usage, phytochemistry, pharmacological activities, and safety of P. bleo. A literature search using MEDLINE (via PubMed), Science direct, Scopus and Google scholar and China Academic Journals Full-Text Database (CNKI) and available eBooks and books in the National University of Singapore libraries in English and Chinese was conducted. The following keywords were used: Pereskia bleo, Pereskia panamensis, Pereskia corrugata, Rhodocacus corrugatus, Rhodocacus bleo, Cactus panamensis, Cactus bleo, Spinach cactus, wax rose, Perescia, and Chinese rose. This review revealed the association between the traditional usage of P. bleo and reported pharmacological properties in the literature. Further investigation on the pharmacological properties and phytoconstituents of P. bleo is warranted to further exploit its potentials as a source of novel therapeutic agents or lead compounds.

Background Migraine is a highly prevalent and disabling disorder of the brain with limited therapeutic options, particularly for preventive treatment. There is a need to identify novel targets and test their potential efficacy in relevant preclinical migraine models. Traditional Chinese medicines have been used for millennia and may offer avenues for exploration. Methods We evaluated two traditional Chinese medicines, gastrodin and ligustrazine, and compared them to two Western approaches with propranolol and levetiracetam, one effective and one ineffective, in an established in vivo rodent model of nociceptive durovascular trigeminal activation. Results Intravenous gastrodin (30 and 100 mg/kg) significantly inhibited nociceptive dural-evoked neuronal firing in the trigeminocervical complex. Ligustrazine (10 mg/kg) and propranolol (3 mg/kg) also significantly inhibited dural-evoked trigeminocervical complex responses, although the timing of responses of ligustrazine does not match its pharmacokinetic profile. Levetiracetam had no effects on trigeminovascular responses. Conclusion Our data suggest gastrodin has potential as an anti-migraine treatment, whereas ligustrazine seems less promising. Interestingly, in line with clinical trial data, propranolol was effective and levetiracetam not. Exploration of the mechanisms and modelling effects of Chinese traditional therapies offers novel route for drug discovery in migraine.

For the assessment of the in vitro anti-protozoal potential of plants traditionally used in Ecuador in the treatment of leishmaniasis, a combined approach based on interviews with healers as well as a literature search was carried out. From three regions of Ecuador, 256 local healers called "Agents of Traditional Medicine" (ATMs) were interviewed about their knowledge of the use of plants to treat and heal the illness recognized by the ATMs as leishmaniasis. From literature sources, 14 plants were identified as being used in the treatment of leishmaniasis. Subsequently, plant material was collected from a representative selection of 39 species. A total of 140 extracts were screened in vitro against Leishmania donovani, Plasmodium falciparum, Trypanosoma brucei rhodesiense and Trypanosoma cruzi. Additionally, these extracts were evaluated for their anti-microbial activities using five gram-positive and -negative bacteria as well as Candida albicans. The survey resulted in 431 use-records for 145 plant-taxa used for the treatment of leishmaniasis. The 10 most frequently reported taxa accounted for 37.7% of all records. In the case of leishmaniasis, activity was observed for Elephantopus mollis, Minquartia guianensis, Bocconia integrifolia, Gouania lupuloides, Scoparia dulcis, an as-yet-unidentified species of Piper and Brugmansia. For the leaves of M. guianensis and the twigs and bark of G. lupuloides a good selectivity index (SI) was found. IC(50) values and the SI of active plant extracts are presented.

The ethanolic extracts of eight traditional Chinese medicines and four antibiotics were investigated for their combined effects on the resistance of Staphylococcus aureus (S. aureus) in vitro. Methicillin resistant S. aureus, which was isolated from patient and a standard strain, were used. Our results showed that there are differences in the effects of many combinations used on the standard strain and resistant strain of S. aureus. The ethanolic extracts of Isatis tinctoria, Scutellaria baicalensis and Rheum palmatum can improve the antimicrobial activity of four antibiotics we used.

Results: All Inuit had a normal OGTT. Fasting glucose (mmol/l, HbA1c (%, total cholesterol (mmol/l and HDL-C (mmol/l were for Qaanaaq women: 4.8±0.2, 5.3±0.1, 4.96±0.42, 1.34±0.06, for Qaanaaq men: 4.9±0.1, 5.7±0.1, 5.08±0.31, 1.28±0.09, for TAB women: 5.1±0.2, 5.3±0.1, 6.22±0.39, 1.86±0.13, for TAB men: 5.1±0.2, 5.3±0.1, 6.23±0.15, 1.60±0.10. No differences were found in systolic or diastolic blood pressure between the groups. There was a more adverse distribution of small dense LDL-C particles and higher total cholesterol and HDL-C concentration in the western diet group. Conclusions: Diabetes or impaired glucose tolerance was not found in the Inuit consuming either the western or the traditional diet, and this could, at least partly, be due to the high amount of regular daily physical activity. However, when considering the total cardio vascular risk profile the Inuit consuming a western diet had a less healthy profile than the Inuit consuming a traditional diet.

Full Text Available Background/purpose: Bacterial infection is closely associated with the failure of endodontic treatment, and use of endodontic sealer with antimicrobial activity and biological compatibility is necessary for the success of root canal treatment. The purpose of this study was to investigate and to compare the antibacterial effect of two calcium silicate-based root canal sealers (Endoseal and EndoSequence BC sealer as recent development sealers and with three conventional root canal sealers (AH Plus, Sealapex, and Tubli-Seal, before or after setting, on Porphyromonas endodontalis, Porphyromonas gingivalis, and Enterococcus faecalis. Materials and methods: The sealers were soaked in phosphate buffered saline to elute its compositions after and before setting, and the elutes were performed the antimicrobial assay. Also, X-ray fluorescence analysis was carried out to compare compositions of two calcium silicate-based sealers. Results: The conventional root canal sealers have strong antibacterial activity against the Gram-negative bacteria, P. endodontalis and P. gingivalis. Endoseal sealer showed antibacterial activity against not only the Gram-negative bacteria, but also against the Gram-positive bacteria, E. faecalis. However, Endosequence BC sealer exhibited a weak antibacterial effect on all bacteria in this study. X-ray fluorescence analysis exhibited that Endoseal contained more types and more amount of the oxide compound known to have strong antimicrobial activity such as Al2O3, Fe2O3, MgO, Na2O, NiO, and SO2 than Endoseqeunce BC. Conclusion: Endoseal, which contains various types of oxide compounds, seems to be a suitable sealer for preventing bacterial infection in both treated and untreated root canals. Keywords: Root canal sealer, Antimicrobial activity, Oxide compound, E. faecalis

This study investigated associations of violence-related behaviors with physical activity (PA)-related behaviors among U.S. high school students. Data from the 2009 national Youth Risk Behavior Survey, a cross-sectional survey of a nationally representative sample of 9th-12th grade students, were analyzed. Sex-stratified, adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated for associations between violence-related behaviors and being physically active for ≥60 minutes daily, sports participation, TV watching for ≥3 hours/day, and video game/computer use for ≥3 hours/day. Among male students, at-school bullying victimization was negatively associated with daily PA (aOR: 0.72; 95% CI: 0.58-0.87) and sports participation; skipping school because of safety concerns was positively associated with video game/computer use (1.42; 1.01-2.00); and physical fighting was positively associated with daily PA. Among female students, at-school bullying victimization and skipping school because of safety concerns were both positively associated with video game/computer use (1.46; 1.19-1.79 and 1.60; 1.09-2.34, respectively), and physical fighting at school was negatively associated with sports participation and positively associated with TV watching. Bullying victimization emerged as a potentially important risk factor for insufficient PA. Schools should consider the role of violence in initiatives designed to promote PA.
Full Text Available Antioxidant activity of lactic acid bacteria is associated with multiple health-protective effects. Traditional indexes of chemical antioxidant activities poorly reflect the antioxidant effects of these bacteria in vivo. Cellular antioxidant activity (CAA assay was used in this study to determine the antioxidant activity of cell-free supernatants (CFSs of 10 Lactobacillus strains. The performance of the CAA assay was compared with that of four chemical antioxidant activity assays, namely, DPPH radical scavenging, hydroxyl radical scavenging (HRS, reducing power (RP, and inhibition of linoleic acid peroxidation (ILAP. Results of the CAA assay were associated with those of DPPH and ILAP assays, but not with those of RP and HRS assays. The inter- and intra-specific antioxidant activities of CFS were characterized by chemical and CAA assays. L. rhamnosus CCFM 1107 displayed a high antioxidative effect similar to positive control L. rhamnosus GG ATCC 53103 in all of the assays. The CAA assay is a potential method for the detection of antioxidant activities of lactobacilli CFSs.

Professionals working with people with dementia need to develop new activities that occupy patients and increase positive emotions. Dementia care mapping is a reliable method of measuring well-being during activities with people with dementia. The iPad has many applications that may be suitable as a group activity for persons with dementia. Six people with dementia took part in two traditional and two iPad activities over two days. Well-being was recorded using dementia care mapping. Subjects displayed similar or better levels of well-being during iPad activities than traditional activities. A larger variation of behaviors was seen during iPad activities than traditional activities. With detailed planning using a person-centred care approach, iPad group activity has the potential to be as effective and engaging as other conventional activities in achieving well-being.

Clerodendrum viscosum , Eryngium foetidum , Lippia javanica , and Murraya koenigii are one among the common wild edible plants in Northeast India which are also used as antidiabetic, stomach-ache relieving drugs, etc., The present study was aimed to reveal the phytochemical, antioxidant, and anthelmintic activity of the plants. The antioxidant capacity of methanolic extract of plants was studied by 1,1-diphenyl-2-picrylhydrazyl (DPPH), ferric reducing antioxidant power, TBARS, and total antioxidant activity (TAA). Total phenolics, flavonoids, Vitamin C, carbohydrate, and protein are also estimated following standard protocols. Anthelmintic activity of the extracts has also been studied in vitro against trematode parasites. The result showed that the methanolic extracts of plants possess a substantial quantity of alkaloids, phenolics, flavonoids, proteins, carbohydrates, and Vitamin C. Phenolics, flavonoids, and Vitamin C contents were found higher in C. viscosum followed by M. koenigii , L. javanica , and E. foetidum . The in vitro antioxidant assays revealed substantial free radical scavenging property in all the plants. TAA increased in the order C. viscosum > M. koenigii > L. javanica > E. foetidum . Similarly, C. viscosum displayed a better antioxidant capacity with IC 50 values 29.74 ± 3.63 μg and 148.77 ± 18.38 μg for DPPH and thiobarbituric acid reactive species, respectively. In addition, the plant extracts also showed good anthelmintic activity against Paramphistomum sp. Time taken for paralysis and death were 0:56 ± 0:09 h and 1:35 ± 0:07 h for L. javanica at 50 mg/mL concentration. The study therefore suggests the importance of tested plants as a natural source of free radical scavenger and plausible veterinary uses.

Implementation science is an emerging area in physical activity (PA) research. We sought to establish the current state of the evidence related to implementation of school-based PA models to explore 1) the relationship between implementation and health outcomes, and 2) factors that influence implementation. We searched 7 electronic databases (1995-2014) and included controlled studies of school-based PA programmes for healthy youth (6-18 y) measuring at least one physical health-related outcome. For objective 1, studies linked implementation level to student-level health outcome(s). For objective 2, studies reported factors associated with implementation. There was substantial variability in how health outcomes and implementation were assessed. Few studies linked implementation and health outcomes (n=15 interventions). Most (11/15) reported a positive relationship between implementation and at least one health outcome. Implementation factors were reported in 29 interventions. Of 22 unique categories, time was the most prevalent influencing factor followed by resource availability/quality and supportive school climate. Implementation evaluation supports scale-up of effective school-based PA interventions and thus population-level change. Our review serves as a call to action to 1) address the link between implementation and outcome within the school-based PA literature and 2) improve and standardize definitions and measurement of implementation.

To assess the quality of evidence for the effects of school active video game (AVG) use on physical activity and health outcomes. Online databases (ERIC, PsycINFO, PubMed, SPORTDiscus, and Web of Science) and gray literature were searched. Inclusion criteria were the use of AVGs in school settings as an intervention; assessment of at least 1 health or physical activity outcome; and comparison of outcomes with either a control group or comparison phase. Studies featuring AVGs within complex interventions were excluded. Study quality was assessed using the Effective Public Health Practice Project tool. Twenty-two reports were identified: 11 assessed physical activity outcomes only, 5 assessed motor skill outcomes only, and 6 assessed both physical activity and health outcomes. Nine out of 14 studies found greater physical activity in AVG sessions compared with controls; mostly assessed by objective measures in school time only. Motor skills were found to improve with AVGs vs controls in all studies but not compared with other motor skill interventions. Effects of AVGs on body composition were mixed. Study quality was low in 16 studies and moderate in the remaining 6, with insufficient detail given on blinding, participation rates, and confounding variables. There is currently insufficient evidence to recommend AVGs as efficacious health interventions within schools. Higher quality AVG research utilizing randomized controlled trial designs, larger sample sizes, and validated activity measurements beyond the school day is needed. Copyright © 2016 Elsevier Inc.

Full Text Available Las practicas matemáticas maoríes fueron excluidas de la escolarización en Aotearoa / Nueva Zelanda durante más de 150 años, como resultado de las políticas explícitas que impiden el uso de la lengua y cultura indígena. Como consecuencia de la gama de políticas asimilacionistas, para la década de 1970, el idioma maorí fue considerado en peligro de extinción. En respuesta a la peligrosa situación de la lengua, las comunidades maoríes crearon sus propias escuelas, en un principio fuera del sistema estatal, para apoyar la revitalización de la lengua y la cultura. Sin embargo, la reintroducción de los conocimientos culturales en áreas como las matemáticas no ha igualado los esfuerzos de revitalización del idioma. Muchas prácticas etnomatemáticas originales ya no son de uso general en la comunidad indígena y las prácticas valoradas por la mayoría de Europa siguen siendo la norma en los programas escolares exigidos por el estado. Orientación espacial es un ejemplo del contenido de los planes de estudio de matemáticas que se basa en perspectivas matemáticas occidentales. Para proporcionar una perspectiva maorí, este documento se basa en entrevistas con los ancianos y los datos históricos para examinar términos de orientación espacial maoríes y los marcos espaciales de las referencias que se derivan de estos. Los estudiantes en una escuela Māori-medium school fueron probados en su comprensión de su conocimiento tradicional. Como consecuencia de ello, una serie de actividades de aprendizaje basadas en conceptos maoríes de orientación espacial se desarrolló y probó. Los resultados de estas actividades de aprendizaje mostraron el aumento de algunos entendimientos sobre conceptos maoríes de orientación espacial.
Full Text Available Twelve medicinal plants and a commercially used drug Ivermectin were examined for insecticidal activity against Melophagus ovinus sheep ked at different time intervals using in vitro adult immersion test. The findings show that at 3.13 µL/mL, 6.25 µL/mL and 12.5 µL/mL concentration of Cymbopogon citratus, Foeniculum vulgare and Eucalyptus globulus essential oils respectively, recorded 100% mortalities against M. ovinus within 3 hour of exposure. Significantly higher insecticidal activity of essential oils was recorded (P=0.00 when compared to 10 μg/mL Ivermectin after 3-hour exposure of M. ovinus at a concentration of ≥1.57 μL/mL, ≥3 μL/mL, and ≥12.7 μL/mL essential oils of C. citratus, F. vulgare, and E. globulus, respectively. Among essential oils, C. citratus has showed superior potency at a three-hour exposure of the parasite (P=0.00 at a concentration of ≥0.78 μL/mL. Strong antiparasitic activity was recorded by aqueous extract of Calpurnia aurea (80% mortality at a concentration of 200 mg/mL within 24 h among aqueous extracts of 9 medicinal plants. The results indicated all the four medicinal plants, particularly those tested essential oils, can be considered as potential candidates for biocontrol of M. ovinus sheep ked.

An investigation of khatrah technique in archery was carried out. An electromyography (EMG) experiment was conducted towards six wrist muscles which are flexor carpi radialis, extensor carpi ulnaris and extensor digitorum communis for both arms. The maximum voluntary contraction (MVC) and activity data were recorded. The bow arm produced a higher muscle force compared to draw arm muscles during release phase. However, the muscle forces produced by bow arm had a consistency in term of pattern throughout the phases. In conclusion, the forces generated by the professional archer produced a force benchmark at the wrist joint to alleviate the risk of injury.

Ten most popular herbs used in Malaysia were analyzed by instrumental neutron activation analysis. A total of 16 trace and major elements were determined and the concentration of elements varied depending on the origin of the herb. Toxic elements found in the samples were below the levels prescribed by health regulations. The mutagenicity test showed that there was no toxic effect due to the heavy metals present in the herbs.

The commercialization of drugs started toward the end of Heian period (794-1192) when not only aristocrats and monks who were traditional patrons to drug makers, but also local clans and landlords who became powerful as a result of the disbanding of aristocratic manors accumulated enough wealth to spend money on medicine. Although traveling around the country was still a dangerous endeavor, merchants assembled groups to bring lucrative foreign drugs (mainly Chinese) to remote areas. The spread of commercial drugs to common people, however, did not happen until the early Edo period (1603-1867), when the so-called barrier system was installed nationwide to make domestic travel safe. Commercialization started in large cities and gradually spread to other areas. Many nostrums popular until recently appeared in the Genroku period (1688-1703) or later. Many such nostrums were all-cures, often consisting of such active ingredients as Saussureae radix, Agalloch, or Gambir. Even in the Edo period, many people living in agricultural or fishing villages, as well as those in the lower tier, were still poor. Much of the medication available to those people was therefore made of various plant or animal-derived substances that were traditionally used as folk medicines.

To assess the dependence on fish consumption of families and its impact on nutritional status and neurodevelopment of pre-school children. Cross-sectional study that measured children's hair mercury (HHg) as an indicator of family fish consumption, growth (anthropometric Z-scores, WHO standards) and neurological (Gesell developmental scores (GDS)) development. Traditional living conditions among families residing in the area adjacent to the Samuel Dam (Western Amazon) hydroelectric reservoir. Two hundred and forty-nine pre-school children (1-59 months of age) from families transitioning from the traditional Amazonian lifestyle. Family fish consumption was significantly correlated with children's HHg concentration (Spearman's r=0.246, P85), multiple regression analysis showed that fish consumption (as HHg) had no impact on GDS, but that some variables did interact significantly with specific domains (motor and language development). The study showed that the families' shift in fish consumption had no negative impact on the growth of young children and that ensuing methylmercury exposure has not been a noticeable neurodevelopmental hindrance.

In Kenya, most people especially in rural areas use traditional medicine and medicinal plants to treat many diseases including malaria. Malaria is of national concern in Kenya, in view of development of resistant strains of Plasmodium falciparum to drugs especially chloroquine, which had been effective and affordable. There is need for alternative and affordable therapy. Many antimalarial drugs have been derived from medicinal plants and this is evident from the reported antiplasmodial activity. The present study reports on the in vivo antimalarial activity and brine shrimp lethality of five medicinal plants traditionally used to treat malaria in Msambweni district, Kenya. A total of five aqueous crude extracts from different plant parts used in traditional medicine for the treatment of malaria were evaluated for their in vivo antimalarial activity using Plasmodium berghei infected Swiss mice and for their acute toxicity using Brine shrimp lethality test. The screened crude plant extracts suppressed parasitaemia as follows: Azadirachta indica (L) Burm. (Meliaceae), 3.1%; Dichrostachys cinerea (L) Wight et Arn (Mimosaceae), 6.3%; Tamarindus indica L. (Caesalpiniaceae), 25.1%; Acacia seyal Del. (Mimosaceae) 27.8% and Grewia trichocarpa Hochst ex A.Rich (Tiliaceae) 35.8%. In terms of toxicity, A.indica root bark extract had an LC50 of 285.8 µg/ml and was considered moderately toxic. T.indica stem bark extract and G.trichocarpa root extract had an LC50 of 516.4 and 545.8 µg/ml respectively and were considered to be weakly toxic while A.seyal and D.cinerea root extracts had a LC50>1000 µg/ml and were therefore considered to be non toxic. The results indicate that the aqueous extracts of the tested plants when used alone as monotherapy had antimalarial activity which was significantly different from that of chloroquine (P≤0.05). The results also suggest that the anecdotal efficacy of the above plants reported by the study community is related to synergism of
Full Text Available The use of fertilizers in cultivation of crops is an objective necessity. However, their use has a negative impact on environment and especially on the soil polluting it with heavy metals. Organic fertilizers can significantly improve physical and chemical soil properties and increase its fertility. In connection with deficiency of manure particular interest represents using of waste as non-conventional fertilizers, in particular waste of alcohol production. Using of high-dose alcohol stillage stronger growth processes and number of leaves, which leads to an increase of maize photosynthetic activity and productivity. Maximum formation of green mass was observed in variant with a dose of making alcohol stillage 40 m3/ha during vegetation.

Full Text Available Microbial processes leading to the production of energy from vegetable biomasses and from residues of the agroindustry make possible the exploitation of widely available and renewable energy sources which can be considered at zero balance with regard to CO2 fixation and emission. These processes show a different level of technological maturity: some of them, like the production of bioethanol or biogas, are well established and diffused processes, while others, like hydrogen production, are in the phase of advanced research. Considering the future prospects, the latter process is the most promising owing to the high calorific value of hydrogen and the absence of polluting emissions when H2 is used for combustions or for the production of electricity with fuel cells. In this review, the research activities carried out, in the field of biogas and hydrogen production, by research groups belonging to the Italian Society for Agricultural, Environmental and Food Microbiology (SIMTREA are presented.

The objective of this study was to identify inequalities in leisure-time physical activity and active commuting to school in Brazilian adolescents, as well as trends according to gender, type of school, maternal schooling, and geographic region, from 2009 to 2015. This was a descriptive study based on data from the Brazilian National School Health Survey (PeNSE) in 2009, 2012, and 2015. Students were defined as active in their leisure time when they practiced at least 60 minutes of physical activity a day on five or more of the seven days prior to the interview. Active commuting to school was defined as walking or biking to school on the week prior to the interview. The outcomes were stratified by gender, type of school, maternal schooling, and geographic region. Inequalities were assessed by differences and ratios between the estimates, as well as summary inequality indices. The 2009, 2012, and 2015 surveys included 61,301, 61,145, and 51,192 schoolchildren, respectively. Prevalence of leisure-time physical activity was 13.8% in 2009, 15.9% in 2012, and 14.7% in 2015; the rates for active commuting to school were 70.6%, 61.7%, and 66.7%, respectively. Boys showed 10 percentage points higher prevalence of leisure-time physical activity and 5 points higher active commuting to school than girls. Children of mothers with more schooling showed a mean of 10 percentage points higher prevalence of leisure-time physical activity than children of mothers with the lowest schooling and some 30 percentage points lower in relation to active commuting to school. The observed inequalities remained constant over the course of the period. The study identified socioeconomic and gender inequalities that remained constant throughout the period and which were specific to each domain of physical activity.

Full Text Available The four plants pathogens, Botrytis cinerea, Phytophthora cinnamomi, Cryphonectria parasitica and Heterobasidion annosum are responsible for several diseases affecting different plant species in Portugal, such as pines (H. annosum, chestnuts (P. cinnamomi and C. parasitica and eucalyptus (B. cinerea. These pathogens incurs in large economic losses, and ultimately causes the death of these plants. The use of biopolymers as antimicrobial agents, such as chitosan (derived from chitin, is increasing, in order to reduce the negative impact of conventional chemical treatments on the environment, avoiding health risks. Therefore, eco-friendly polymers were produced through (1 N-acetylation with addition of acetic anhydride and (2 hydrogen peroxide of chitosan samples, obtained from two different sources: shrimp (commercial chitosan and swimming crab bycatch specie Polybius henslowii. The chemical structure and molecular weight of the prepared chitosan derivatives, water soluble chitosan (WSC and chitooligosaccharides (COS, was confirmed by Fourier Transform Infrared (FT-IR and Gel Permeation Chromatography (GPC and their antifungal activity evaluated against Botrytis cinerea, Phytophthora cinnamomi, Cryphonectria parasitica and Heterobasidion annosum. The concentration range varied from 0.0125 to 0.1 mg/mL and inhibition percentages were determined by differences in radial growth on the agar plates for all species. Although not all species tested exhibited equal vulnerability towards the concentrations range, antifungal activity of chitosan samples proved to be dependent, increasing the inhibitory capacity with lower concentrations. The results obtained support the use of chitosan fromPolybius henslowii when compared with commercial chitosan with shrimp towards antifungal approaches, suggesting that chitin producers can rely on this crab waste as a raw material for chitin extraction, adding value to this bycatch specie. Financial support was obtained
Full Text Available It is acknowledged that parental engagement with children’s learning and education is of vital importance. But, there is a tendency to confuse engagement with learning with engagement with the school. While all types of parents’ involvement can have a positive effect, it is actually what parents do with their child at home that has the greatest impact. However, unless parental involvement in learning is embedded in whole-school processes it is unlikely to as effective as possible. This paper documents an action research study that explores the inclusion of parents and home values in the construction of the teaching and learning environment. This was a small step towards positive parent-teacher collaboration, which allowed an exchange of knowledge, values and cultural background experiences. In acknowledging the ways in which the parents already engaged with their children’s learning, it began to enhance self-efficacy in their ability to directly affect this learning. This work has also provoked reflexive engagement of my influence and understanding of involving parents of children with additional and diverse learning needs. But, it also details the transformative journey that influenced my thinking about how we as a school could begin to develop whole-school processes to directly involve parents in policy development and school activities.

Peroxisome proliferator-activated receptors (PPAR)-γ is widely used as an attractive target for the treatment of type 2 diabetes mellitus. Thiazolidinediones, the agonists of PPARγ, has been popularly utilized as insulin sensitizers in the therapy of type 2 diabetes whereas numerous severe side-effects may also occur concomitantly. The PPARγ activation activity of different polar extracts, including petroleum ether, ethyl acetate, n-butanol, residual of ethanol, the precipitate part of water and the supernatant of water extracts, from 37 traditional Chinese medicines were systematically evaluated. HeLa cells were transiently co-transfected with the re-constructed plasmids of GAL4-PPARγ-ligand binding domain and pGL4.35. The activation of PPARγ by different polarity extracts were evaluated based on the PPARγ transactivation assay and rosiglitazone was used as positive control. Seven medicines (root bark of Lycium barbarum, Anoectochilus sroxburghii, the rhizome of Phragmites australis, Pterocephalus hookeri, Polygonatum sibiricum, fruit of Gleditsia sinensis, and Epimedium brevicornu) were able to significantly activate PPARγ. As seven medicines were able to activate PPARγ, the anti-diabetic activity of them is likely to be mediated by this nuclear receptor. Lots of the tested medicinal products had activation effects on activating PPARγEthyl acetate extracts of root bark of L.barbarum, rhizome of P.saustralis and fruit of G.siasinensis showed good PPARγ activation effect similar or higher than that of positive control, 0.5 μg/mL rosiglitazonePetroleum ether extracts of A.roxburghii, P. hookeri, P. sibiricum, E.brevicornu also can significantly activate PPARγ, the effects of them were higher than t0.5 μg/mL rosiglitazoneSchisandra chinensis (Turcz.)

Full Text Available The aim of this work was to isolate and to characterize strains of lactic acid bacteria (LAB with bacteriocin-like inhibitory activity from 27 traditional cheeses artisanal-produced obtained from different Peruvian regions. Twenty Gram+ and catalasenegative strains among 2,277 isolates exhibited bacteriocin-like inhibitory activity against Listeria monocytogenes CWBIB2232 as target strain. No change in inhibitory activity was observed after organic acid neutralization and treatment with catalase of the cell-free supernatant (CFS. The proteinic nature of the antimicrobial activity was confirmed for the twenty LAB strains by proteolytic digestion of the CFS. Two strains, CWBI-B1431 and CWBI-B1430, with the best antimicrobial activity were selected for further researches. These strains were taxonomically identified by phenotypic and genotypic analyses as Enterococcus mundtii (CWBI-B1431 and Enterococcus faecium (CWBI-B1430. The two strains were sensitive to vancomycin (MIC 2 μg.ml-1 and showed absence of haemolysis.

Aqueous and methanolic extracts from different parts of nine traditional Zulu medicinal plants, of the Vitaceae from KwaZulu-Natal, South Africa were evaluated for therapeutic potential as anti-inflammatory and anti-microbial agents. Of the twenty-nine crude extracts assayed for prostaglandin synthesis inhibitors, only five methanolic extracts of Cyphostemma natalitium-root, Rhoicissus digitata-leaf, R. rhomboidea-root, R. tomentosa-leaf/stem and R. tridentata-root showed significant inhibition of cyclo-oxygenase (COX-1). The extracts of R. digitata-leaf and of R. rhomboidea-root exhibited the highest inhibition of prostaglandin synthesis with 53 and 56%, respectively. The results suggest that Rhoicissus digitata leaves and of Rhoicissus rhomboidea roots may have the potential to be used as anti-inflammatory agents. All the screened plant extracts showed some degrees of anti-microbial activity against gram-positive and gram-negative microorganisms. The methanolic extracts of C. natalitium-stem and root, R. rhomboidea-root, and R. tomentosa-leaf/stem, showed different anti-microbial activities against almost all micro-organisms tested. Generally, these plant extracts inhibited the gram-positive micro-organisms more than the gram-negative ones. Several plant extracts inhibited the growth of Candida albicans while only one plant extract showed inhibitory activity against Saccharomyces cerevisiae. All the plant extracts which demonstrated good anti-inflammatory activities also showed better inhibitory activity against Candida albicans.

Full Text Available In this research, positive and negative effects of club activities, the difficulties students had and the thoughts of teachers on how to conduct club activities effective are tried to be determined. In the research,where qualitative research and interview techniques are applied, ten teachers who work in Ankara Tevfik Fikret Private Elementary School, are chosen incidentally to be interviewed. During the interviews with the teachers, four questions were asked and their answers were recorded. Datas were resolved with descriptive analysis and these results were found: Teachers think that these club activities help students to discover and improve their interests and talents and help them to learn how to socialise and work with a plan. These activities also improves their general knowledge, creative thinking skills and push them to take responsibility. According to teachers, normally club activities have no negative effects on students but some problems can occur because of not choosing the suitable club according to student’s interests and talents. The most frequent problems that teachers face during club activities are the insufficiency of time, not being able to find an appropriate place to perform club activities and lack of material and activity variations. Due to these reasons, teachers offered to extend the spare time of club activities and they also offered to find new and more appropriate places and enriching materials for club activities. After all those suggestions, teachers requested students to channel themselves to club activities according to their interests and talents.

The Israeli Health Promoting School Network (HPSN) is actively committed to enhancing a healthy lifestyle for the entire school population. This study aimed to explore the contribution of school participation in the HPSN and students' individual characteristics to healthy eating and physical activity habits among Israeli school children aged 10-12 years. A cross-sectional survey was conducted among 4166 students in grades 4-6 from 28 schools. The schools were selected from a sample of HPSN affiliated and non-HPSN schools. The contribution of individual characteristics (grade, gender and subjective self-reported health education activities at school) and school characteristics (school type, population group, deprivation score) to healthy eating and physical activity habits was analyzed using multi-level hierarchical models. Multi-level analysis indicated that student's individual characteristic was significantly associated with healthy eating and physical activity habits. The subjective self-reported health education received at school was statistically significant factor associated with students' health behaviors. The school's affiliation with the HPSN was not associated with higher healthy eating and physical activity scores after adjusting for individual factors. These findings suggest that Israeli HPSN schools do not contribute to children's health behaviors more than other schools. Therefore, health promoting activities in HPSN schools need to be improved to justify their recognition as members of the HPS network and to fulfill their mission. © The Author 2017.

This cross-sectional study examined differences in children's health behaviors during school term (ST) versus school holiday (SH: June-July) and how associations changed when weather characteristics were considered. Children aged 5-18 years (n = 406) from a subtropical climate reported behaviors over 20 months. Multivariable regression models controlling for age, sex, race and body mass index z-score (BMIz) were used to examine associations between SH and each behavior. A second model included heat index, precipitation and daylight hours. Strenuous activity, moderate activity, total activity and TV viewing were significantly higher during SH than ST. After adjusting for weather characteristics, total activity remained significantly higher during SH, but the association with TV viewing was attenuated. Youth surveyed during high precipitation were significantly less likely to meet physical activity guidelines. There were no significant associations between SH and meeting sleep, physical activity or screen-time guidelines. Weather characteristics influenced associations between SH and youth's physical activity and TV viewing.

Full Text Available Abstract Background Studies examining the correlates of school transport commonly fail to make the distinction between morning and afternoon school trips. The purpose of this study was to examine the prevalence and correlates of mode shift from passive in the morning to active in the afternoon among elementary and secondary school students in Ontario, Canada. Methods Data were derived from the 2009 cycle of the Ontario Student Drug Use and Health Survey (OSDUHS. 3,633 students in grades 7 through 12 completed self-administered questionnaires. Socio-demographic, behavioural, psychological, and environmental predictors of active school transport (AST were assessed using logistic regression. Results Overall, 47% and 38% of elementary school students reported AST to and from school, respectively. The corresponding figures were 23% and 32% for secondary school students. The prevalence of AST varied temporarily and spatially. There was a higher prevalence of walking/biking found for elementary school students than for secondary school students, and there was an approximate 10% increase in AST in the afternoon. Different correlates of active school transport were also found across elementary and secondary school students. For all ages, students living in urban areas, with a shorter travel time between home and school, and having some input to the decision making process, were more likely to walk to and from school. Conclusions Future research examining AST should continue to make the analytic distinction between the morning and afternoon trip, and control for the moderating effect of age and geography in predicting mode choice. In terms of practice, these variations highlight the need for school-specific travel plans rather than 'one size fits all' interventions in promoting active school transport.

Four wild berry species, Amelanchier alnifolia, Viburnum trilobum, Prunus virginiana, and Shepherdia argentea, all integral to the traditional subsistence diet of Native American tribal communities, were evaluated to elucidate phytochemical composition and bioactive properties related to performance and human health. Biological activity was screened using a range of bioassays that assessed the potential for these little-known dietary berries to affect diabetic microvascular complications, hyperglycemia, pro-inflammatory gene expression, and metabolic syndrome symptoms. Nonpolar constituents from berries, including carotenoids, were potent inhibitors of aldose reductase (an enzyme involved in the etiology of diabetic microvascular complications), whereas the polar constituents, mainly phenolic acids, anthocyanins, and proanthocyanidins, were hypoglycemic agents and strong inhibitors of IL-1beta and COX-2 gene expression. Berry samples also showed the ability to modulate lipid metabolism and energy expenditure in a manner consistent with improving metabolic syndrome. The results demonstrate that these berries traditionally consumed by tribal cultures contain a rich array of phytochemicals that have the capacity to promote health and protect against chronic diseases, such as diabetes.

Full Text Available This article presents a pedagogical experience in Financial Management classes. The objective of this study was to investigate whether the educational activity based on active methodologies, applied in the Financial Management classes in an undergraduate course in Business Administration, can offer formative spaces that enhance the development of the students’ intrinsic motivation to the point of being relevant to the development of their autonomy and thus to be characterized as a viable manner of putting the Freirean pedagogy into practice. In order to do so, the adopted teaching strategy aimed at creating opportunities for interpretating problems that simulated real situations. A questionnaire was applied and the Bardinian content analysis was used to verify the students' impressions about the activity itself and its respective contribution to their professional and personal training. The analysis points to the fact that active methodologies are viable alternatives to the traditional method of teaching regarding the awakening of interest, motivation and the development of learning. It also points to their consonance with the Freirian pedagogy.
Full Text Available The article identifies salient features of Van de Ruit’s novels “Spud: a wickedly funny novel” (2005 and “Spud – the madness continues” (2007 and compares them with the corresponding motifs commonly found in historical British boys’ school stories, tracing shifts in discourse to establish the novels’ construction of a South African boyhood. The article argues that through his conscious subversion of the imperial model’s defining discourses, Van de Ruit’s fictional representation of Spud’s school experience portrays the previously accepted “ideal” construction of boyhood, with its unmistakably defined principles and uncontested ethical code, as fundamentally challenged by the variety of alternative discourses to which the modern protagonist is exposed. The resultant construction of Spud’s South African boyhood is, therefore, characterised by the protagonist’s constant struggle to assimilate the frequently incongruous and bewildering discourses (about moral courage and personal integrity, in particular that compete for his attention. The pivotal component of this particular construction of boyhood may be argued not to be a strict adherence to a clearly defined schoolboy ethic, but as a variable that is ultimately dependent on the boy’s choices.

Full Text Available This paper outlines the use of a form of research intervention known as the Change Laboratory to illustrate how the processes of organisational change initiated at a secondary school can be applied to develop tools and practices to analyse and potentially re-make educational traditions in a bottom-up manner. In this regard it is shown how a cultural-historical activity theory (CHAT perspective can be combined with a relational approach to generate the theoretical and practical tools for managing change at a school. Referring to an ongoing research project at a school, the paper describes how teachers and management there, with the aid of the researcher, attempt to re-configure their educational praxis by drawing on past, present and future scenarios from their schooling activity. These are correlated with similarly historically evolving theoretical models and recorded empirical data using the Vygotskyian method of double stimulation employed by the Change Laboratory. A relational conceptualisation of the school’s epistemological, pedagogical and organisational traditions is used to map out the connections between various actors, resources, roles and divisions of labour at the school. In this way the research intervention proposes a model of educational change that graphically represents it as a network of mediated relationships so that its artefacts, practices and traditions can be clearly understood and effectively manipulated according to the shared objectives of the teachers and school management. Such a relationally-oriented activity theory approach has significant implications in terms of challenging conventional processes of educational transformation as well as hegemonic knowledge-making traditions themselves.

The Child Behavior Checklist (CBCL was used for evaluation of mental health problems of the schoolchildren, Physical Activity Questionnaire for Older Children (PAQ-C, for evaluation of the physical activity levels of the subject, and a social-demographic questionnaire. Results: Most children were classified as sedentary (80% and only 7.3% of the sample showed positive for trace of mental disorder. No significant association was found between mental disorders and physical activity levels among the group, or between these variables and socio-demographic characteristics of children. It was observed that the girls were more sedentary than boys, with significant difference (p < 0.01. Conclusion: Despite the low prevalence of mental health problems among schoolchildren and the non-association with physical activity levels, special attention is necessary with this audience, aiming to strengthen physical activity as a protective factor for children’s mental health, with investments in actions aimed at the encouragement of regular practice of physical activity, combining family and school. Studies with a larger number of samples need to be conducted and its findings must be thoroughly analyzed.

The relationship between students’ school environment and exercise habits is complex, and is affected by numerous factors. However, the few studies that have been conducted on this relationship have reported inconsistent results, especially regarding Taiwanese students. We conducted this cross-sectional study to investigate the association of school environment and after-school physical activity with health-related physical fitness in Taiwanese adolescents. Data were drawn from a national survey conducted by the Ministry of Education in Taiwan in 2008 of health-related physical fitness measurements among junior high school students (649,442 total) in grades seven to nine. School environment (level of urbanization, school size, presence of sports field or gymnasium) and after-school physical activity were assessed for their association with adolescents’ physical fitness measurements (body mass index (BMI), bent-leg sit-ups, 800-/1600-m run, sit-and-reach, standing long jump). Urban boys and girls perform significantly better in muscle strength and endurance, cardiorespiratory endurance, flexibility, and explosive power; girls from rural areas exhibited significantly worse scores in body composition. Boys from large-size schools performed the worst in cardiorespiratory endurance, flexibility, and explosive power; whereas girls from large-size schools performed the worst in muscle strength, muscle endurance, and explosive power, but had the best score for body composition. However, the differences in body composition of boys from large-, medium-, and small- size schools did not reach a statistically significant level. Adolescents of both genders in schools with a sports field or gymnasium exhibited significantly better in muscle strength and endurance, cardiorespiratory endurance, and explosive power. Boys in schools with a sports field or gymnasium had significantly better body composition; girls in schools with sports field or gymnasium differed significantly in

Although interventions targeting the health of students in schools are becoming common, few studies have examined how health messages operate at the group level in school environments. This study examines the effects of message-based health interventions (extrinsic vs. intrinsic goal framing) in group environments (exergame competitive vs. exergame noncompetitive) on eliciting attitudes and intentions toward physical activity among children and adolescents. We conducted a 7-week school-based intervention program involving 336 children and 259 adolescents in Singapore in which pre- and post-intervention responses were recorded. Our findings revealed the difference in responses between child and adolescent groups. Children who participated in noncompetitive exergames with extrinsically framed health messages and those who participated in competitive exergames with intrinsically framed health messages demonstrated more favorable attitudes toward physical activity. However, the same effects were absent in our adolescent group. These findings suggest that the integration of exergames into competitive and noncompetitive environments can serve as a gateway to traditional physical activity in schools when strategically combined with intrinsically and extrinsically framed messages. Practical and theoretical implications for schools and health educators are discussed.

This study examined the impact of a 12-wk. sport stacking intervention on reaction time (RT), manual dexterity, and hand-eye coordination in elementary school-aged children. 80 Grade 2 students participated in a 15-min. sport stacking practice session every school day for 12 wk., and were tested on psychomotor performance improvement. Tests for choice RT, manual dexterity, and photoelectric rotary pursuit tracking were conducted pre- and post-intervention for both experimental group (n = 36) and the controls (n = 44) who did no sport stacking. Students who had the intervention showed a greater improvement in two-choice RT. No other group difference was found. Such sport stacking activities may facilitate children's central processing and perceptual-motor integration.

This paper exploits state health education (HED) reforms as quasi-natural experiments to estimate the causal impact of HED received by children on their parents' physical activity. We use data from the Panel Study of Income Dynamics for the period 1999-2005 merged with data on state HED reforms from the National Association of State Boards of Education Health Policy Database and the 2000 and 2006 School Health Policies and Programs Study. To identify the spillover effects of HED requirements on parents' behavior, we use several methodologies (triple differences, changes in changes, and difference in differences) in which we allow for different types of treatments. We find a positive effect of HED reforms at the elementary school on the probability of parents doing light physical activity. Introducing major changes in HED increases the probability of fathers engaging in physical activity by between 6.3 and 13.7 percentage points, whereas on average, this probability for mothers does not seem to be affected. We analyze several heterogeneous impacts of the HED reforms to unveil the mechanisms behind these spillovers. We find evidence consistent with hypotheses such as gender specialization of parents in childcare activities or information sharing between children and parents.

Detailed acoustical measurements were made in 34 active elementary school classrooms with typical rectangular room shape in schools near Ottawa, Canada. There was an average of 21 students in classrooms. The measurements were made to obtain accurate indications of the acoustical quality of conditions for speech communication during actual teaching activities. Mean speech and noise levels were determined from the distribution of recorded sound levels and the average speech-to-noise ratio was 11 dBA. Measured mid-frequency reverberation times (RT) during the same occupied conditions varied from 0.3 to 0.6 s, and were a little less than for the unoccupied rooms. RT values were not related to noise levels. Octave band speech and noise levels, useful-to-detrimental ratios, and Speech Transmission Index values were also determined. Key results included: (1) The average vocal effort of teachers corresponded to louder than Pearsons Raised voice level; (2) teachers increase their voice level to overcome ambient noise; (3) effective speech levels can be enhanced by up to 5 dB by early reflection energy; and (4) student activity is seen to be the dominant noise source, increasing average noise levels by up to 10 dBA during teaching activities.

This study was conducted to evaluate effects of traditional Chinese medicine formula (TCMF) combined with several herbs on ruminal fermentation, enzyme activities and nutrient digestibility. Twenty finishing bulls were assigned to control or different TCMFs (Yufeisan-1, -2, -3; 2.5% dry matter (DM) in concentrate). Results showed that DM intake was higher (P < 0.05) in the Yufeisan-3 group than others. Compared to control, apparent digestibility of crude protein and neutral detergent fiber were increased (P < 0.05) by Yufeisan-3. No changes were observed in ruminal pH, concentrations of ammonia-N, microbial crude protein and total volatile fatty acid, whereas ratio of acetate to propionate was lower (P < 0.05) and propionate proportion tended to be higher (P < 0.1) in three TCMFs than control. Ruminal xylanase (P = 0.061) and carboxymethylcellulase (P < 0.05) activities were higher in Yufeisan-3 than control. No changes were observed in abundance of total bacteria, fungi and protozoa, whereas Fibrobacter succinogenes (P = 0.062) and Ruminococcus flavefaciens (P < 0.05) were increased and total methanogens was reduced (P = 0.069) by Yufeisan-3 compared to control. Yufeisan-3 improved nutrient digestibility and ruminal enzyme activity, and modified fermentation and microbial community, maybe due to the presence of Herba agastaches, Cortex phellodendri and Gypsum fibrosum. © 2018 Japanese Society of Animal Science.

The purpose of this study was to measure the acute effects of pre-exhaustion vs. traditional exercise order on neuromuscular performance and sEMG in trained men. Fourteen young, healthy, resistance trained men (age: 25.5 ± 4.0 years, height: 174.9 ± 4.1 cm, and total body mass: 80.0 ± 11.1 kg) took part of this study. All tests were randomized and counterbalanced for all subjects and experimental conditions. Volunteers attended one session in the laboratory. First, they performed ten repetition maximum (10RM) tests for each exercise (bench press and triceps pushdown) separately. Secondly, they performed all three conditions at 10RM: pre-test (bench press and triceps pushdown, separately), pre-exhaustion (triceps pushdown+bench press, PE) and traditional (bench press+triceps pushdown, TR), and rested 30 minutes between conditions. Results showed that pre-test was significantly greater than PE (p = 0.031) but not different than TR, for total volume load lifted. There was a significant difference between the pre-test and the time-course of lactate measures (p = 0.07). For bench press muscle activity of the pectoralis major, the last repetition was significantly greater than the first repetition (pre-test: p = 0.006, PE: p = 0.016, and TR: p = 0.005). Also, for muscle activity of the triceps brachii, the last repetition was significantly greater than the first repetition (pre-test: p = 0.001, PE: p = 0.005, and TR: p = 0.006). For triceps pushdown, muscle activity of the triceps brachii, the last repetition was significantly greater than the first repetition (pre-test: p = 0.006, PE: p = 0.016, and TR: p = 0.005). For RPE, there were no significant differences between PE and TR (p = 0.15). Our results suggest that exercise order decreases repetitions performed, however, neuromuscular fatigue, lactate, and RPE are not impacted. The lack of difference in total volume load lifted between PE and TR might explain, at least in part, the similar metabolic and perceptual

Full Text Available The article presents testing results of educational cases. The cases were developed for first grade students based on «The world around us» topical area. The sample included 84 first-grade pupils of the two Moscow schools. The experimental group participated in development activities. The article presents fragments of two developing classes based on a textbook «The world around us» by A.A. Pleshkov. Classes were based on discussion of the methasubject content of the such various phenomena as characteristics of living and nonliving, the existence of things in different historical time (now and 200 years ago. In this paper the ability to analyze, compare, to establish causal relationships, to reflect the mode of action were considered as methasubject competencies. Development of these competencies in school-children was evaluated by the diagnosis method based on A.Z. Zak theoretical thinking. According to the diagnosis results, after the developmental activities, metasubject competencies development indicators in the experimental group significantly improved in comparison with indicators prior to specialized training. Figures have not changed in the control group, so the data lead to the conclusion that the educational cases content has a positive effect on the development of metasubject competencies in first year school children.

Full Text Available Purpose. To examine the relationship between diet, physical activity, and obesity in Indigenous youths from northern Australia. Methods. In a cross-sectional study, physical activity and dietary intake (“short nutrition questionnaire” were assessed among all youths during a face-to-face interview. For 92 high school youths, additional dietary information was assessed using a food-frequency questionnaire. Height and weight were measured and BMI was calculated. Multiple logistic regression was used to assess associations. Results. Of the 277 youths included, 52% had ≤2 servings of fruit and 84% had <4 servings of vegetables per day; 65% ate fish and 27%, take-away food (“fast food” at least twice a week. One in four ate local traditional sea food including turtle and dugong (a local sea mammal at least twice a week. Overweight/obese youths engaged in fewer days of physical activity in the previous week than normal weight youths (OR=2.52, 95% CI 1.43–4.40, though patterns of physical activity differed by sex and age (P<0.001. Overweight/obese youths were 1.89 times (95% CI 1.07–3.35 more likely to eat dugong regularly than nonobese youths. Analysis of food-frequency data showed no difference by weight assessment among high-school students. Conclusions. Low fruit and vegetable intake were identified in these Indigenous youths. Regular consumption of fried dugong and low frequency of physical activity were associated with overweight/obesity reinforcing the need to devise culturally appropriate health promotion strategies and interventions for Indigenous youths aimed at improving their diet and increasing their physical activity.
Full Text Available Abstract Background Active commuting to school has declined over time, and interventions are needed to reverse this trend. The main objective was to investigate the effects of a school-based intervention on active commuting to school and health-related fitness in school-age children of Southern Spain. Methods A total of 494 children aged 8 to 11 years were invited to participate in the study. The schools were non-randomly allocated (i.e., school level allocation into the experimental group (EG or the control group (CG. The EG received an intervention program for 6 months (a monthly activity focused on increasing the level of active commuting to school and mainly targeting children’s perceptions and attitudes. Active commuting to school and health-related fitness (i.e., cardiorespiratory fitness, muscular fitness and speed-agility, were measured at baseline and at the end of the intervention. Children with valid data on commuting to school at baseline and follow-up, sex, age and distance from home to school were included in the final analysis (n = 251. Data was analyzed through a factorial ANOVA and the Bonferroni post-hoc test. Results At follow up, the EG had higher rates of cycling to school than CG for boys only (p = 0.04, but not for walking to school for boys or girls. The EG avoided increases in the rates of passive commuting at follow up, which increased in the CG among girls for car (MD = 1.77; SE = 0.714; p = 0.010 and bus (MD = 1.77; SE = 0.714; p = 0.010 modes. Moreover, we observed significant interactions and main effects between independent variables (study group, sex and assessment time point on health-related fitness (p < 0.05 over the 6-month period between groups, with higher values in the control group (mainly in boys. Conclusion A school-based intervention focused on increasing active commuting to school was associated with increases in rates of cycling to school among boys, but not for

The participants were randomly selected and assigned to either the experimental group (n = 33 which studied through blended e-learning or the control group (n = 32 which studied through traditional classroom learning. The experiment lasted for five weeks. The results showed that (a there were no significant differences in achievement test scores between blended e-learning and traditional learning; (b students in the experimental group obtained significantly higher scores on self-assessment than students in the control group; (c students’ scores on self-assessment were significantly higher after studying through blended e-learning than before. Overall, blended e-learning did not significantly affect students’ achievement test scores, but significantly affected their self-assessment scores.
Sixty percent of America's teachers choose traditional baccalaureate programs while the remaining choose one of several alternative pathways. While certification/training is certainly important to preparing effective teachers, other research indicates that teacher efficacy serves as the foundation of teacher behaviors and classroom practice. The purpose of this study ( N = 94 induction high school science teachers) was to determine the relationships between certification pathway and opportunities to observe modeling; between years of experience and personal teaching efficacy; and teachers' perceptions of what characteristics/ experiences best explain personal teaching efficacy. The Teacher Sense of Efficacy Scale was used in an on-line survey for Phase 1 (n = 91), to measure teacher self-efficacy. In Phase 2, a basic qualitative study was conducted using telephone interviews ( n = 2) and a focus group (n = 4) along with a series of short essay questions from the online survey (n = 91). The findings indicate a significant relationship (p = 0.01) between years of teaching and overall personal teaching-efficacy, student engagement, and instructional strategies; a relationship between opportunities to see modeling and certification pathway, where traditionally certified teachers had significantly more opportunities (p = 0.000); and a relationship between classroom management and opportunities to see modeling (p = 0.005). Qualitative analyses confirmed that traditionally-prepared teachers saw a range of "modeling" and model teachers; respondents related such opportunities to more effective teaching, especially in the realm of classroom management. As more teachers choose alternative certification, it is imperative that adequate opportunities to observe teaching strategies are modeled during the certification process and once teachers enter the classroom; they must have intrinsic and extrinsic support to be successful.

We examined the effect of a comprehensive school physical activity program (CSPAP) on gross motor skills in children. Participants were 959 children (1st-6th grade; Mean age = 9.1 ± 1.5 years; 406 girls, 553 boys) recruited from 5 low-income schools receiving a year-long CSPAP intervention. Data were collected at the beginning of the school year and at a 36-week follow-up. Gross motor skills were assessed using the Test for Gross Motor Development (3rd ed.) (TGMD-3) instrument. Multi-level mixed effects models were employed to examine the effect of CSPAP on TGMD-3 scores, testing age and sex as effect modifiers and adjusting for clustering of observations within the data structure. There were statistically significant coefficients for time (β = 8.1, 95% CI [3.9, 12.3], p skills and ball skills sub-test scores. Children showed improved gross motor skill scores at the end of the 36-week CSPAP that were modified by age, as younger children displayed greater improvements in TGMD-3 scores compared to older children.

Full Text Available Background: Probiotics are living microorganisms that have useful effects on health of digestive system when acquired in a defined dosage. E. coli O157:H7 is known as one of the most important agents of diarrhea in developing countries. Therefore, attention to the treatment of such gastrointestinal disease is essential. The aim of this study was to determine antagonistic activity of food born lactobacilli against E. coli O157:H7.Methods: Lactobacilli were isolated from traditional dairy products (yogurt and buttermilk samples. Then, they were characterized using biochemical and molecular tests. Bifidobacterium bifidum PTCC 1644 was obtained from the microbial collection of Iranian Research Organization for Science and Technology in Lyophilized form. Similarly, E. coli O157:H7 PTCC12900 was obtained from faculty of veterinary medicine university of Tehran. The antagonistic activity of probiotics supernatants against E. coli O157:H7 was investigated using the disk diffusion agar, well diffusion agar and pour plate methods.Results: The isolates were characterized as Lactobacillus plantarum and Lactobacillus fermentum. All isolates showed antagonistic activities against E. coli O157:H7 in all of the three methods, where the activity of L. plantarum and B. bidifum PTCC 1644 was greater than that of L. fermentum. Conclusion: Metabolites produced by the probiotic bacteria are able to inhibit the growth of E. coli O157:H7. This can be an important solution for the prevention and treatment of E. coli O157:H7 infection and ultimately improve human health.

Millets are a diverse group of small seeded grasses, widely grown around the world as cereal foods. This communication details the proximate, mineral profile and antioxidant activity of six different small millets (Finger, Foxtail, Proso, Little, Barnyard and Kodo millets) and their 21 cultivars that are traditionally cultivated and consumed in the region of Ralayaseema, south India. The proximate analysis revealed that these millets are rich in protein, fat, ash (mineral), total dietary fibre and total phenols with appreciable antioxidant activity. However, starch and amylose content was comparatively lower as compared to major millet sorghum. ICP-MS analysis of small millets demonstrated that they are rich in minerals such as Ca, P, K, Mg, Fe, Cu, Zn, Mn, Cr, Mo and Se. Finger and kodo millets were found to be nutritionally superior over other small millets. The results suggest that small millets have a potential to provide food security and can combat micronutrient malnutrition. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Urokinase plasminogen activator (uPA) and plasminogen activator inhibitor type-1 (PAI-1) play a key role in tumour invasion and metastasis. High levels of both proteolytic enzymes are associated with poor prognosis in breast cancer patients. The purpose of this study was to evaluate the correlation between traditional prognostic factors and uPA and PAI-1 expression in primary tumour of breast cancer patients. 606 primary breast cancer patients were enrolled in the prospective study in the Department of gynaecological oncology and breast oncology at the University Medical Centre Maribor between the years 2004 and 2010. We evaluated the traditional prognostic factors (age, menopausal status, tumour size, pathohistological type, histologic grade, lymph node status, lymphovascular invasion and hormone receptor status), together with uPA and PAI-1. We used Spearman’s rank correlation, Mann Whitney U test and χ 2 test for statistical analysis. Our findings indicate a positive correlation between uPA and tumour size (p < 0.001), grade (p < 0.001), histological type (p < 0.001), lymphovascular invasion (p = 0.01) and a negative correlation between uPA and hormone receptor status (p < 0.001). They also indicate a positive correlation between PAI-1 and tumour size (p = 0.004), grade (p < 0.001), pathohistological type (p < 0.001) and negative correlation between PAI-1 and hormone receptor status (p = 0.002). Our study showed a relationship between uPA and PAI-1 and traditional prognostic factors. Their role as prognostic and predictive factors remains to be further evaluated

Parkinson's disease (PD) is a multifactorial neurodegenerative disorder affecting 5% of the population over the age of 85 years. Current treatments primarily involve dopamine replacement therapy, which leads to temporary relief of motor symptoms but fails to slow the underlying neurodegeneration. Thus, there is a need for safe PD therapies with neuroprotective activity. In this study, we analyzed contemporary herbal medicinal practices used by members of the Pikuni-Blackfeet tribe from Western Montana to treat PD-related symptoms, in an effort to identify medicinal plants that are affordable to traditional communities and accessible to larger populations. The aims of this study were to (i) identify medicinal plants used by the Pikuni-Blackfeet tribe to treat individuals with symptoms related to PD or other CNS disorders, and (ii) characterize a subset of the identified plants in terms of antioxidant and neuroprotective activities in cellular models of PD. Interviews of healers and local people were carried out on the Blackfeet Indian reservation. Plant samples were collected, and water extracts were produced for subsequent analysis. A subset of botanical extracts was tested for the ability to induce activation of the Nrf2-mediated transcriptional response and to protect against neurotoxicity elicited by the PD-related toxins rotenone and paraquat. The ethnopharmacological interviews resulted in the documentation of 26 medicinal plants used to treat various ailments and diseases, including symptoms related to PD. Seven botanical extracts (out of a total of 10 extracts tested) showed activation of Nrf2-mediated transcriptional activity in primary cortical astrocytes. Extracts prepared from Allium sativum cloves, Trifolium pratense flowers, and Amelanchier arborea berries exhibited neuroprotective activity against toxicity elicited by rotenone, whereas only the extracts prepared from Allium sativum and Amelanchier arborea alleviated PQ-induced dopaminergic cell death

Malaria is an old life-threatening parasitic disease that is still affecting many people, mainly children living in sub-Saharan Africa. Availability of effective antimalarial drugs played a significant role in the treatment and control of malaria. However, recent information on the emergence of P. falciparum parasites resistant to one of the artemisinin-based combination therapies suggests the need for discovery of new drug molecules. Therefore, this study aimed to evaluate the antiplasmodial activity of extracts, fractions and isolated compound from medicinal plants traditionally used in the treatment of malaria in Tanzania. Dry powdered plant materials were extracted by cold macerations using different solvents. Norcaesalpin D was isolated by column chromatography from dichloromethane root extract of Caesalpinia bonducella and its structure was assigned based on the spectral data. Crude extracts, fractions and isolated compound were evaluated for antiplasmodial activity against chloroquine-sensitive P. falciparum (3D7), chloroquine-resistant P. falciparum (Dd2, K1) and artemisinin-resistant P. falciparum (IPC 5202 Battambang, IPC 4912 Mondolkiri) strains using the parasite lactate dehydrogenase assay. The results indicated that extracts of Erythrina schliebenii, Holarrhena pubescens, Dissotis melleri and C. bonducella exhibited antiplasmodial activity against Dd2 parasites. Ethanolic root extract of E. schliebenii had an IC 50 of 1.87 μg/mL while methanolic and ethanolic root extracts of H. pubescens exhibited an IC 50 = 2.05 μg/mL and IC 50 = 2.43 μg/mL, respectively. Fractions from H. pubescens and C. bonducella roots were found to be highly active against K1, Dd2 and artemisinin-resistant parasites. Norcaesalpin D from C. bonducella root extract was active with IC 50 of 0.98, 1.85 and 2.13 μg/mL against 3D7, Dd2 and IPC 4912-Mondolkiri parasites, respectively.

Full Text Available The aim of this study was to determine physical activity levels of children during school recess, taking into account children’s perceptions as well as observations during recess. A mixed method was used, including the System for Observing Play and Leisure Activity in Youth (SOPLAY and focus groups. Participants included students from 3 public schools with regular and alternating schedules, who were observed during their school breaks. In addition, focus groups were held and descriptive statistics were used. A factorial variance test (2x2 was also used to determine if there were differences between levels of moderate-vigorous physical activity among school types. Results of focus groups were organized into categories. Students exhibited 47.98 sedentary activity and 52.02 moderate-vigorous physical activity during school recess, with girls being more sedentary than boys. Students with an alternating schedule are more active than those with a regular schedule. Participants perceived reduced space to play and little support from teachers as barriers to do physical activity. In conclusion, this study showed that a little over 50% of students perform physical activity during school recess, with children in alternating schedules being more active than those with a regular schedule. Participants perceive that school environment does not favor physical activity, due to environmental barriers. Based on the results of this study, physical activity should be promoted during school recess, taking into consideration barriers in natural, social, physical, and organizational environments.

Airag is a traditional fermented milk of Mongolia that is usually made from raw mare's milk. Lactobacillus helveticus is one of the lactic acid bacteria most frequently isolated from airag. In this study, we investigated the genetic and physiological characteristics of L. helveticus strains isolated from airag and clarified their significance in airag by comparing them with strains from different sources. Six strains of L. helveticus were isolated from five home-made airag samples collected from different regions of Mongolia. The optimal temperature for acidification in skim milk was 30 to 35°C for all the Mongolian strains, which is lower than those for the reference strains (JCM 1554 and JCM 1120(T)) isolated from European cheeses. All of the strains had a prtH1-like gene encoding a variant type of cell envelope proteinase (CEP). The CEP amino acid sequence in Snow Brand Typeculture (SBT) 11087 isolated from airag shared 71% identity with PrtH of L. helveticus CNRZ32 (AAD50643.1) but 98% identity with PrtH of Lactobacillus kefiranofaciens ZW3 (AEG40278.1) isolated from a traditional fermented milk in Tibet. The proteolytic activities of the CEP from SBT11087 on artificial substrate (N-succinyl-Ala-Ala-Pro-Phe-p-nitroanilide) and pure casein were measured using an intact-cell degradation assay. The activity of the CEP from SBT11087 was observed to be weak and exhibited a lower optimal temperature (40°C) than those from the reference strains (45-50°C). The specificity of the SBT11087 CEP for αS1-casein was typical of the CEPs previously reported in L. helveticus, as determined through the degradation profiles obtained through gel electrophoresis and mass spectrometry analyses. In contrast, the degradation profile of β-casein revealed that the CEP of SBT11087 primarily hydrolyzes its C-terminal domain and hydrolyzed nine of the 16 cleavage sites shared among the CEPs of other L. helveticus strains. Thus, the CEP of SBT11087 is distinct from those from

Active transportation to school is a method by which youth can build physical activity into their daily routines. We examined correlates of active transportation to school at both individual- (characteristics of the individual and family) and area- (school and neighborhood) levels amongst youth living within 1 mile (1.6 km) of their school. Using the 2009/10 Canadian Health Behaviour in School-Aged Children (HBSC) survey, we selected records of students (n = 3 997) from 161 schools that resided in an urban setting and lived within 1 mile from their school. Student records were compiled from: (1) individual-level HBSC student questionnaires; (2) area-level administrator (school) questionnaires; and (3) area-level geographic information system data sources. The outcome, active transportation to school, was determined via a questionnaire item describing the method of transportation that individual students normally use to get to school. Analyses focused on factors at multiple levels that potentially contribute to student decisions to engage in active transportation. Multi-level logistic regression analyses were employed. Approximately 18% of the variance in active transportation was accounted for at the area-level. Several individual and family characteristics were associated with engagement in active transportation to school including female gender (RR vs. males = 0.86, 95% CI: 0.80-0.91), having ≥2 cars in the household (RR vs. no cars = 0.87, 0.74-0.97), and family socioeconomic status (RR for 'not well off' vs. 'very well off' = 1.14, 1.01-1.26). Neighborhood characteristics most strongly related to active transportation were: the length of roads in the 1 km buffer (RR in quartile 4 vs. quartile 1 = 1.23, 1.00-1.42), the amount of litter in the neighborhood (RR for 'major problem' vs. 'no problem' = 1.47, 1.16-1.57), and relatively hot climates (RR in quartile 4 vs. quartile 1 = 1.33 CI, 1.05-1.53). Engagement in active transportation to school was related

Full Text Available Abstract Background Whilst evidence exists for the influence of encouragement on physical activity participation, the diversity of support sources and the type of physical activity examined previously is limited. This study examined the importance of perceived encouragement from parents, siblings/cousins, friends, and schools on participation levels across three time-specific activity opportunities that are available during a school day (after-school physical activities, lunchtime activity, and active transportation to and from school. Methods A cross-sectional sample of 12–18 year old high school students (n = 3,471 were recruited from low SES schools within South Auckland, New Zealand and categorised as either Junior (Years 9–11 or Senior (Years 12 & 13 students. Participants reported their physical activity levels and quantity of encouragement received from their parent(s, friend(s, sibling(s/cousin(s, and school to be active. For each physical activity variable participants were dichotomized as being either "active" or "less active". For each social support source, participants were grouped into either receiving "high" or "low" levels of support. Binary logistic regression analyzes were conducted to calculate odd ratios and 95% confidence intervals. Results Low parental support (Juniors, OR: 0.47, 95% CI: 0.38–0.58; Seniors, OR: 0.41, 95% CI: 0.29–0.60 and low peer support (Juniors, OR: 0.61, 95% CI: 0.51–0.74; Seniors, OR: 0.49, 95% CI: 0.35–0.69 were associated with reduced odds of being regularly active after school. For lunchtime activity, low peer support (Juniors, OR: 0.39, 95% CI: 0.32–0.48; Seniors, OR: 0.41, 95% CI: 0.29–0.57 was associated with reduced odds of being categorized as active. While no variables were significantly related to active transportation among senior students, low peer support was associated with reduced odds of actively commuting for Junior students (OR: 0.78, 95% CI: 0.66–0.92.

Although active school travel (AST) is important for increasing moderate-to-vigorous physical activity (MVPA), it is unclear how AST is related to context-specific physical activity and non-school travel. This study investigated how school travel is related to physical activity and travel behaviours across time- and space-classified domains. A total of 196 adolescents wore a Global Positioning System receiver and an accelerometer for 7 days. All data were classified into one of four domains: home, school, transport, or leisure. Generalized linear mixed models were used to compare domain-specific PA and non-school trips between active and passive school travellers. Active travellers accumulated 13 and 14 more min of MVPA on weekdays and weekend days, respectively. They also spent 15min less time in vehicular travel during non-school trips, and accrued an additional 9min of MVPA while walking on weekend days. However, those with no AST still achieved most of their MVPA in the transport domain. AST is related to out-of-school physical activity and transportation, but transport is also important for those who do not use AST. As such, future studies should consider overall mobility and destinations other than school when assessing travel and physical activity behaviours. Copyright © 2016 Elsevier Ltd. All rights reserved.
Full Text Available Abstract Background Physical activity (PA rates decline precipitously during the high school years and are consistently lower among adolescent girls than adolescent boys. Due to cultural barriers, this problem might be exacerbated in female Iranian adolescents. However, little intervention research has been conducted to try to increase PA participation rates with this population. Because PA interventions in schools have the potential to reach many children and adolescents, this study reports on PA intervention research conducted in all-female Iranian high schools. Methods A randomized controlled trial was conducted to examine the effects of two six-month tailored interventions on potential determinants of PA and PA behavior. Students (N = 161 were randomly allocated to one of three conditions: an intervention based on Pender's Health Promotion model (HP, an intervention based on an integration of the health promotion model and selected constructs from the Transtheoretical model (THP, and a control group (CON. Measures were administered prior to the intervention, at post-intervention and at a six-month follow-up. Results Repeated measure ANOVAs showed a significant interaction between group and time for perceived benefits, self efficacy, interpersonal norms, social support, behavioral processes, and PA behavior, indicating that both intervention groups significantly improved across the 24-week intervention, whereas the control group did not. Participants in the THP group showed greater use of counter conditioning and stimulus control at post-intervention and at follow-up. While there were no significant differences in PA between the HP and CON groups at follow-up, a significant difference was still found between the THP and the CON group. Conclusion This study provides the first evidence of the effectiveness of a PA intervention based on Pender's HP model combined with selected aspects of the TTM on potential determinants to increase PA among

Full Text Available The practice of physical activity (PA has recently been used as a stimulant to improve the cognitive performance in young people and to have positive repercussions on the academic performance . The aims of this research were to conceptualize the relationship between PA and cognition, as well as to associate different physical qualities with better or worse school performance, and thus to be able to make decisions about the kind of PA more adequate to foment from the educative and familiar areas. Our findings are in line with previous literature, and show that a higher physical fitness is associated with better school performance. In conclusion, our study suggests that it is necessary to strengthen the daily PA practice within school context, as well as to raise awareness among families and society about PA promotion.

The present study examined differences in dietary habits and physical activity levels between students attending private and public high schools in Jordan. A total of 386 secondary-school males and 349 females aged 14-18 years were randomly recruited using a multistage, stratified, cluster sampling technique. Dietary habits and physical activity level were self-reported in a validated questionnaire. The prevalence of obesity was significantly higher among adolescents in private (26.0%) than in public schools (16.7%). The frequency of breakfast intake was significantly higher among adolescents in private schools, whereas French fries and sweets intake was significantly higher in public schools. Television viewing showed a significant interaction with school type by sex. A higher rate of inactivity was found among students attending private schools. Despite a slightly better overall dietary profile for students in private schools, they had a higher rate of overweight and obesity compared with those in public schools.
Full Text Available Traditional Chinese Marine Medicine (TCMM represents one of the medicinal resources for research and development of novel anticancer drugs. In this study, to investigate the presence of anticancer activity (AA displayed by cold or hot nature of TCMM, we analyzed the association relationship and the distribution regularity of TCMMs with different nature (613 TCMMs originated from 1,091 species of marine organisms via association rules mining and phylogenetic tree analysis. The screened association rules were collected from three taxonomy groups: (1 Bacteria superkingdom, Phaeophyceae class, Fucales order, Sargassaceae family, and Sargassum genus; (2 Viridiplantae kingdom, Streptophyta phylum, Malpighiales class, and Rhizophoraceae family; (3 Holothuroidea class, Aspidochirotida order, and Holothuria genus. Our analyses showed that TCMMs with closer taxonomic relationship were more likely to possess anticancer bioactivity. We found that the cluster pattern of marine organisms with reported AA tended to cluster with cold nature TCMMs. Moreover, TCMMs with salty-cold nature demonstrated properties for softening hard mass and removing stasis to treat cancers, and species within Metazoa or Viridiplantae kingdom of cold nature were more likely to contain AA properties. We propose that TCMMs from these marine groups may enable focused bioprospecting for discovery of novel anticancer drugs derived from marine bioresources.
Full Text Available Traditional Chinese medicine (TCM formula has been playing a very important role in health protection and disease control for thousands of years. Guided by TCM syndrome theories, formula are designed to contain a combination of various kinds of crude drugs that, when combined, will achieve synergistic efficacy. However, the precise mechanism of synergistic action remains poorly understood. One example is a famous TCM formula Yinchenhao Tang (YCHT, whose efficacy in treating hepatic injury (HI and Jaundice syndrome, has recently been well established as a case study. We also conducted a systematic analysis of synergistic effects of the principal compound using biochemistry, pharmacokinetics and systems biology, to explore the key molecular mechanisms. We had found that the three component (6,7-dimethylesculetin (D, geniposide (G, and rhein (R combination exerts a more robust synergistic effect than any one or two of the three individual compounds by hitting multiple targets. They can regulate molecular networks through activating both intrinsic and extrinsic pathways to synergistically cause intensified therapeutic effects. This paper provides an overview of the recent and potential developments of chemical fingerprinting coupled with systems biology advancing drug discovery towards more agile development of targeted combination therapies for the YCHT.

The ethnopharmacology for treatment of parasitic infections facilitates and directs the search for new chemical entities. In this direction, this study evaluated the cytotoxicity in vitro, against trophozoites of Giardia lamblia, of aqueous extracts of leaves Achyrocline satureioides (Lam.) DC., barks of Eugenia uniflora L., aerial parts of Foeniculum vulgare Miller, and barks of Psidium guajava L. These plants are traditionally used for the treatment of diarrhea by the indigenous population Mbyá-Guarani, located at the Lomba do Pinheiro, Porto Alegre, Rio Grande do Sul, Brazil. The in vitro susceptibility qualitative analysis of G. lamblia to aqueous extracts was performed in serial dilutions from 2.5 to 0.02 mg/mL. Results revealed the minimal inhibitory concentrations: 0.313 mg/mL for A. satureioides and E. uniflora, 0.02 mg/mL for P. guajava, and F. vulgare did not present any cytotoxic effect. Quantitative assays of viable trophozoites, showed that A. satureioides presented the highest cytotoxic effect (93.5%), followed by P. guajava (82.2%), and E. uniflora (67.3%). Indigenous Guarani use mainly A. satureioides for the treatment of diarrhea, revealing the conformity with results obtained in vitro. Bioguided assays are necessary to identify the compounds responsible for the activity of the aqueous extract of A. satureioides.

School-based physical activity (PA) interventions, including school active transportation (AT), provide opportunities to increase daily PA levels, improves fitness, and reduces risk of diseases, such as type 2 diabetes. Based on a community-identified need, the Kahnawake Schools Diabetes Prevention Project, within an Indigenous community, undertook school travel planning to contribute to PA programming for two elementary schools. Using community-based participatory research, the Active & Safe Routes to School's School Travel Planning (STP) process was undertaken in two schools with an STP-Committee comprised of community stakeholders and researchers. STP activities were adapted for local context including: school profile form, family survey, in-class travel survey, pedestrian-traffic observations, walkability checklist, and student mapping. STP data were jointly collected, analyzed and interpreted by researchers and community. Traffic-pedestrian observations, walkability and parent surveys identified key pedestrian-traffic locations, helped develop safe/direct routes, and traffic calming strategies. In-class travel and mapping surveys identified a need and student desire to increase school AT. The STP-Committee translated findings into STP-action plans for two schools, which were implemented in 2014-2015 school year. Combining CBPR with STP merges community and researcher expertise. This project offered evidence-informed practice for active living promotions. Experience and findings could benefit Indigenous and non-Indigenous communities. Copyright © 2016 Elsevier Ltd.

To break through the restrictions of the evaluation model and the quantity of compounds by using the two-dimensional zebrafish model combined with chromatographic techniques, and establish a new method for the high-throughput screening of active anti-osteoporosis components. According to the research group-related studies and relevant foreign literatures, on the basis of the fact that the zebrafish osteoporosis model could efficiently evaluate the activity, the zebrafish metabolism model could efficiently enrich metabolites and the chromatographic techniques could efficiently separate and analyze components of traditional Chinese medicines, we proposed that the inherent combination of the three methods is expected to efficiently decode in vivo and in vitro efficacious anti-osteoporosis materials of traditional Chinese medicines. The method makes it simple and efficient in the enrichment, separation and analysis on components of traditional Chinese medicines, particularly micro-components and metabolites and the screening anti-osteoporosis activity, fully reflects that efficacious materials of traditional Chinese medicines contain original components and metabolites, with characteristic of "multi-components, multi-targets and integral effect", which provides new ideas and methods for the early and rapid discovery of active anti-osteoporosis components of traditional Chinese medicines.

School based oral health education through traditional lecturing has been found successful only in improving oral health knowledge, while has low effectiveness in oral hygiene and gingival health. The aim of this study was to evaluate the effectiveness of experiential learning (EL) oral health education to traditional lecturing (TL), on enhancing oral health knowledge, attitude and behavior as well as oral hygiene, gingival health and caries of 10-year-old children. Eighty-four children were recruited for the EL and 100 for the TL group from 3 locations in Greece. Data regarding oral health knowledge, attitude and behavior were collected via questionnaires. Data regarding dental plaque, gingivitis and caries were collected by clinical examination. The evaluation using questionnaires and clinical examination was assessed at baseline and 6 and 18 months afterwards. Two calibrated pediatric dentists examined the students using a periodontal probe and artificial light. Modified hygiene index (HI) was used for dental plaque recording, the simplified gingival index (GI-S) was used for gingivitis and DMFT, based on BASCD criteria, for dental caries. Based on a dedicated manual, the teacher applied in the classroom the oral health educational program using EL. EL group had statistically significant better hygiene than the TL at 6 months (p 0.05) and attitude (p > 0.05) at 6 months in comparison to baseline. EL program was found more successful than TL in oral hygiene improvement. Both oral health education programs improved the oral health knowledge, attitude and behavior of children.

Full Text Available Schools must generate answers to social challenge that the ageing population raises. The main objective of this research is to evaluate the benefits that could involve the implementation of a intergenerational program, focused on radio, in educational centers.These benefits keep relation with intergenerational learning, active ageing and the safeguard of intangible cultural heritage. In order to develope this investigation, we have approached the design, development and evaluation of a intergenerational program mediated by radio. It took place in a classroom of primary education from CPI Virxe da Cela de Monfero (A Coruña. According with it, we have selected a program evaluation methodology. In addition, we have used interviews and participant observation as a method. This labour has allowed us to show how the synergy between intergenerational programs and radio can increase benefits related to the breaking of stereotypes, the betting on lifelong learning or social inclusion. All of them aspects enable us to establish a debate about responsibility and the way in which the school can contribute to the generation of a society for all ages.

Nontraditional college students (older, part-time, and/or working) have less healthful nutrition and physical activity behaviors compared to traditional students, yet few health promotion efforts focus on nontraditional students. The purpose of this study was to use qualitative methods to explore factors affecting nutrition and physical activity behaviors of nontraditional students. Fourteen semi-structured individual interviews were conducted with nontraditional undergraduate students attending a large university. The sample had a median age of 25 (range, 21-64), 57% were men, 43% were racial/ethnic minorities, and 57% were employed (mean 22 hours/week). Data were coded using a systematic team-based approach. Consistent themes (mentioned by 4+ students) were identified and categorized into three domains: home, work, and school. Home (themes: neighborhood characteristics, family, partners), work (theme: work environment), and school (themes: cafeteria, vending machines) factors consistently influenced positive nutrition behaviors. Similarly, home (themes: neighborhood including safety, friends from home, partner,), work (theme: work environment), and school (themes: not having a car, campus structure, campus gym, friends at school) factors consistently influenced positive physical activity. Financial resources and perceptions of autonomy had influence across domains. Results indicate consistent influences on nutrition and physical activity behaviors across home, work, and school domains for nontraditional college students. Study findings suggest possible, and sometimes unconventional, intervention strategies to promote healthful eating and physical activity. For example, when cafeteria meal plans are not offered and financial constraints limit eating at the cafeteria, encouraging healthful choices from vending machines could be preferable to not eating at all.

The prevalence of school students at risk of anaphylaxis in Victoria is unknown and has not been previously studied. Similarly, rates of adrenaline autoinjector usage in the school environment have yet to be determined given increasing prescription rates. We sought to determine time trends in prevalence of school children at risk of anaphylaxis across all year levels and the annual usage rate of adrenaline autoinjectors in the school setting relative to the number of students at risk of anaphylaxis. Statewide surveys from more than 1,500 government schools including more than 550,000 students were used and prevalence rates (%) with 95% CIs were calculated. The overall prevalence of students at risk of anaphylaxis has increased 41% from 0.98% (95% CI, 0.95-1.01) in 2009 to 1.38% (95% CI, 1.35-1.41) in 2014. There was a significant drop in reporting of anaphylaxis risk with transition from the final year of primary school to the first year of secondary school, suggesting a change in parental reporting of anaphylaxis risk among secondary school students. The number of adrenaline autoinjectors activated per 1000 students at risk of anaphylaxis ranged from 6 to 8 per year, with consistently higher activation use in secondary school students than in primary school students. Statewide prevalence of anaphylaxis risk has increased in children attending Victorian government schools. However, adrenaline autoinjector activation has remained fairly stable despite known increase in the rates of prescription. Copyright © 2016 American Academy of Allergy, Asthma & Immunology.

Paediatric overweight and obesity is recognised as one of Australia's most significant health problems and effective approaches to increasing physical activity and reducing energy consumption are being sought urgently. Every potential approach and setting should be subjected to critical review in an attempt to maximise the impact of policy and program initiatives. This paper identifies the strengths and limitations of schools as a setting for promoting physical activity. The strengths are: most children and adolescents attend school; most young people are likely to see teachers as credible sources of information; schools provide access to the facilities, infrastructure and support required for physical activity; and schools are the workplace of skilled educators. Potential limitations are: those students who like school the least are the most likely to engage in health-compromising behaviours and the least likely to be influenced by school-based programs; there are about 20 more hours per week available for physical activity outside schools hours than during school hours; enormous demands are already being made on schools; many primary school teachers have low levels of perceived competence in teaching physical education and fundamental movement skills; and opportunities for being active at school may not be consistent with how and when students prefer to be active.

Feedback is one of the most powerful tools, which teachers can use to enhance student learning. It appears difficult for teachers to give qualitatively good feedback, especially during active learning. In this context, teachers should provide facilitative feedback that is focused on the development of meta-cognition and social learning. The purpose of the present study is to contribute to the existing knowledge about feedback and to give directions to improve teacher feedback in the context of active learning. The participants comprised 32 teachers who practiced active learning in the domain of environmental studies in the sixth, seventh, or eighth grade of 13 Dutch primary schools. A total of 1,465 teacher-student interactions were examined. Video observations were made of active learning lessons in the domain of environmental studies. A category system was developed based on the literature and empirical data. Teacher-student interactions were assessed using this system. Results. About half of the teacher-student interactions contained feedback. This feedback was usually focused on the tasks that were being performed by the students and on the ways in which these tasks were processed. Only 5% of the feedback was explicitly related to a learning goal. In their feedback, the teachers were directing (rather than facilitating) the learning processes. During active learning, feedback on meta-cognition and social learning is important. Feedback should be explicitly related to learning goals. In practice, these kinds of feedback appear to be scarce. Therefore, giving feedback during active learning seems to be an important topic for teachers' professional development. © 2012 The British Psychological Society.
