In this fascinating look at the "alpha male," primatologist Frans de Waal explores the privileges and costs of power while drawing surprising parallels between how humans and primates choose their leaders. His research reveals some of the unexpected capacities of alpha males -- generosity, empathy, even peacekeeping -- and sheds light on the power struggles of human politicians. "Someone who is big and strong and intimidates and insults everyone is not necessarily an alpha male," de Waal says.
There is a growing interest in the use of mindfulness-based interventions (MBI) on youth, which has recently expanded to include the study of students in school settings. This article systematically reviewed the existing literature of applied studies using MBI with students in school settings in order to identify limitations in the scientific literature and inform future research directions. Twenty-eight studies were selected for review and were coded across multiple domains, including methodologies employed, student characteristics, intervention characteristics, and outcome variables. Results quantitatively summarized the coded variables, and strengths and limitations in the literature were subsequently identified. We conclude with specific recommendations for future interventions scientists wishing to study the utility of MBI in school settings.

PURPOSE: The purpose of this systematic review was to summarise the evidence from randomised controlled trials examining the effectiveness of physical therapy compared with care as usual or a wait-list condition on eating pathology and on physiological and psychological parameters in patients with anorexia and bulimia nervosa. METHOD: EMBASE, PsycINFO, PubMed, Cumulative Index to Nursing and Allied Health Literature, Physiotherapy Evidence Database and The Cochrane Library were searched from their inception until February, 2013. Articles were eligible if they utilised a randomised controlled trial design, compared physical therapy with a placebo condition, control intervention, or standard care and included patients with anorexia and bulimia nervosa. The methodological quality was assessed with the Jadad scale. RESULTS: Eight randomised controlled trials involving 213 patients (age range: 16-36 years) met all selection criteria. Three of the 8 included studies were of strong methodological quality (Jadad score>/=3). Major methodological weaknesses were attrition and selection bias. The main results demonstrate that aerobic and resistance training result in significantly increased muscle strength, body mass index and body fat percentage in anorexia patients. In addition, aerobic exercise, yoga, massage and basic body awareness therapy significantly lowered scores of eating pathology and depressive symptoms in both anorexia and bulimia nervosa patients. No adverse effects were reported. CONCLUSIONS: The paucity and heterogeneity of available studies limits overall conclusions and highlights the need for further research. Implications for Rehabilitation Supervised physical therapy might increase weight in anorexia nervosa patients. Aerobic exercise, massage, basic body awareness therapy and yoga might reduce eating pathology in patients with anorexia and bulimia nervosa. Aerobic exercise, yoga and basic body awareness therapy might improve mental and physical quality of life in patients with an eating disorder.
PURPOSE: Since a distorted body experience and a sedentary lifestyle are central in the course of binge eating disorder (BED), physical therapy might be an interesting add-on treatment. The aim of this study was to systematically review randomised controlled trials (RCTs) evaluating physical therapy on binge eating and physical and mental health in BED patients. METHOD: EMBASE, PsycINFO, PubMed, Cumulative Index to Nursing and Allied Health Literature, Physiotherapy Evidence Database and Cochrane Library were searched from their inception until 15 August 2012 for relevant RCTs comparing physical therapy with a placebo condition, control intervention or standard care. RESULTS: Three RCTs involving 211 female community patients (age range: 25-63 years) met all selection criteria. Review data demonstrate that aerobic and yoga exercises reduce the number of binges and the body mass index (BMI) of BED patients. Aerobic exercise also reduces depressive symptoms. Only combining cognitive behavioural therapy (CBT) with aerobic exercise and not CBT alone reduces BMI. Combining aerobic exercise with CBT is more effective in reducing depressive symptoms than CBT alone. CONCLUSIONS: The limited number of available studies and the heterogeneity of the interventions limit overall conclusions and highlight the need for further research. IMPLICATIONS FOR REHABILITATION: Because of severe co-morbid psychiatric and physical conditions, binge eating disorder is one of the most difficult psychiatric conditions to treat. Both yoga and aerobic exercise have shown promise in reducing binge eating pathology and weight. Combining aerobic exercise with cognitive behavioural therapy seems more effective in reducing depressive symptoms than cognitive behavioural therapy alone.
Ethnopharmacological relevanceSyzygium cumini (L.) Skeels (Myrtaceae), commonly known as “jambolão” in Brazil is widely used in folk medicine against leishmaniasis, inflammation, chronic diarrhea, and ulcers. It is one of the most commonly used plants for the treatment of diabetes worldwide. In previous studies, Syzygium cumini was shown to possess antihyperlipidemic and anti-allergic properties, and to exhibit good performance as an antimicrobial agent against bacteria, fungi, and protozoa parasites of the genus Leishmania and Trypanosoma. This study was aimed at evaluating the effects of S. cumini essential oil (ScEO) and its major component α-pinene on Leishmania (Leishmania) amazonensis, as well as their cytotoxicity and possible mechanisms of action.
Materials and methods
To evaluate the anti-proliferative effect on Leishmania, effects on promastigote and axenic amastigote forms were assessed using tetrazolium salt (MTT) assay. The intramacrophagic amastigotes were exposed to ScEO and α-pinene to determine the survival index. To gain insight into the mechanism of action involved in the effect on the samples, we evaluated the modulation of macrophage activation state by observing structural (phagocytic and lysosomal activities) and cellular (nitric oxide increase) changes. To assess the safety profile of ScEO and α-pinene, murine macrophages and human red blood cells were treated with ScEO and α-pinene and the selectivity index was calculated for each treatment.
Results
α-Pinene was effective against Leishmania amazonensis promastigote forms, with a half-maximal inhibitory concentration (IC50) value of 19.7µg/mL. α-Pinene was more active (IC50 values of 16.1 and 15.6µg/mL against axenic and intracellular amastigotes, respectively) than ScEO (IC50 values of 43.9 and 38.1µg/mL against axenic and intracellular amastigotes, respectively). Our results showed that the anti-Leishmania effects were mediated by immunomodulatory activity, as evidenced by the observed increases in both phagocytic and lysosomal activity, and the elevated NO levels. ScEO and α-pinene exhibited low cytotoxicity against murine macrophages and human erythrocytes. The 50% cytotoxicity concentration (CC50) values for the macrophages in the MTT assay were 614.1 and 425.2µg/mL for ScEO and α-pinene, respectively, while the corresponding half-maximal hemolytic concentration (HC50) values were 874.3 and 233.3µg/mL.
Conclusions
Taken together, the results demonstrate that ScEO and its major constituent α-pinene have significant anti-Leishmania activity, modulated by macrophage activation, with acceptable levels of cytotoxicity in murine macrophages and human erythrocytes. Further work is warranted, involving more in-depth mechanistic studies and in vivo investigations.
<i>Tangles and Webs</i>, by Buddhist scholar in the Theravāda tradition Padmasiri De Silva, uses existential philosophy and the psychoanalytic tradition to interpret and understand Buddhist teachings. The author upon draws on Freud, Kierkegaard, Heidegger, Satre and others with the idea that existentialism is more a "tone of voice" than a systemized intellectual ideology. De Silva particularly focuses on the Buddhist concept of suffering (dukkha). Tying together Buddhist and existential ideas is the concept of the "human tangle," an idea elaborated on in one Buddhist text: "Tangles within, tangles without, entangled is the race of sentient beings." The author weaves this theme to the broader existential views on anxiety and alienation. The book ends with a postscript on therapy which looks at existential approaches to the treatment of psychopathology as found in existential psychology and phenomenology-based psychiatry.

Mobile devices, such as laptops, smartphones and tablets, are ubiquitous in lectures. Students report to use their mobile devices for lecturerelated activities (e.g. taking notes). Observational data shows, that students use mobile device mainly for lecture-unrelated activities, like Facebook or playing games. So currently, mobile devices seem to distract learners from the lecture and ultimately hinder student-teacher interaction. In this study, we investigated how students (n = 75) use their mobile devices (N = 80) in a traditional lecture setting when supported with the technological support system “Backstage” or not. Backstage entails functions for quizzing students (Audience-ResponseSystem) and a backchannel allowing students to interact with each other, commenting on slides, asking questions, and providing feedback to lecturers. The results show that this technology increases students’ focus on lecture-related activities.

INTRODUCTION: Tibetan medicine (TM) is a whole systems medical approach that has had growing interest in the West. However, minimal research, particularly with cancer, has been conducted. The purpose of this article is to provide an overview of TM and describe a clinical case review study to obtain preliminary evidence of TM's safety and effect on patients treated for cancer or hematologic disorders.METHODS: A retrospective case review was conducted in India and cases met the following inclusion criteria: (a) confirmed diagnosis of cancer or hematologic disorder by standard Western biomedical diagnostic tests, (b) either treated exclusively with TM or received insufficient Western treatment followed by TM and (c) were in remission or had stable disease at least 2 years after start of TM.
RESULTS: Three cases were identified, 1 solid tumor and 2 hematologic diseases: Case 1--poorly to moderately differentiated adenocarcinoma of the stomach, positive lymph nodes and mucosal infiltration, with clear scans and excellent quality of life 29 months later ; Case 2--chronic myelogenous leukemia with normalization of hematologic labs within 3 months of starting TM and stable 4 years later; and Case 3--red cell aplasia improved significantly and reversed dependence on blood transfusions with TM. None of the cases experienced demonstrable adverse effects from TM.
CONCLUSIONS: This limited case review found TM to be safe and have positive effects on quality of life and disease regression and remission in patients with cancer and blood disorders. Further exploration and investigation using rigorous methods is warranted.

Fatigue is a common symptom in multiple sclerosis (MS). As fatigue includes a variety of aspects, its treatment is best approached in a multidisciplinary fashion that includes nonpharmacological interventions and medications. In individuals with mild fatigue non-pharmacological treatment including yoga, aerobic exercises, cooling therapy and energy conservation techniques might be considered. Several pharmacological treatments for patients with significant fatigue have proved to be effective. Among these agents, amantadine and aminopyridines are the most frequently used. More recently also aspirin and carnitine have been used to treat MS fatigue but they need to be confirmed in larger studies.
Construction of a multidisciplinary conceptual framework of environmental quality and quality of life is required to advance the field of urban development, environmental quality and human well-being. Such a framework would allow for a more theory-based choice of indicators and for the development of tools to evaluate multidimensional aspects of urban environmental quality. These tools are required to assess the current and future quality of the urban environment and to have, eventually, the ability to assess the implications of spatial and urban planning policies with respect to these dimensions. Against this background, the National Institute for Public Health and the Environment in the Netherlands (RIVM) performed a major literature review [Leidelmeijer, van Kamp, 2002, in press] to identify various concepts in the literature concerning environmental quality, the relationships between these various concepts, as well as their respective theoretical bases. This paper summarises the outcomes of this survey. It reviews the main (types of) concepts of livability, environmental quality, quality of life and sustainability, and presents examples of underlying conceptual models. Different notions and concepts are compared along the dimensions of domain, indicator, scale, time-frame and context as described by [Urban Environmental Quality—a social geographical perspective, this issue]. It is concluded that a multidisciplinary conceptual framework of environmental quality and quality of life that will go beyond the disciplinary differences found in the current literature is needed if the field is to advance.
For over 20 centuries, Buddhism has been the spiritual practice of the majority of Sri Lankans. Though Buddhist practices have been increasingly influencing psychotherapy in the West, the use of such practices in psychotherapy in Sri Lanka is not common. This paper attempts to bridge this gap by presenting a case study where Buddhist mindfulness practice was used successfully in the treatment of a case of obsessive compulsive disorder. This paper also presents an outline of the association between Buddhist mindfulness practice and mindfulness practices used in modern-day psychotherapy and discusses issues in the use of mindfulness practice in psychotherapy.

This study evaluated the degree to which a range of social emotional learning skills--academic self-efficacy, academic motivation, social connections, importance of school, and managing psychological and emotional distress and academic stress--could be used as an indicator of future academic outcomes. Using a sample of 4,797 from a large urban school district, we found that high school students classified as performing in the lowest 25% of their grade reported lower social emotional skills than students classified in the top 25% of academic performers by the end of the 8th grade. Two variables, perceived importance of attending college and psychological and physical stress, accounted for nearly 26% of the variance in cumulative high school GPA after controlling for 9th-grade GPA. Finally, the results indicated that a combination of 5 social emotional learning subscales effectively discriminated between students making positive progress towards high school graduation and those identified as having dropped out of or failed more than 14% of their courses.

BACKGROUND: Soft tissue injury imposes major public health burdens worldwide. The positive effect of China's Tibetan medicine and the Lamiophlomis rotata-based herbal Pain Relieving Plaster (PRP) on healing closed soft tissue injury (CSTI) has been reported. The herbs contained in Plaster are also referred as 'blood-activating and stasis-dispelling' in herbal medicine. The formula of the plaster contains four China's Tibetan medical herbs, including Lamiophlomis rotata, Oxytropis falcate Bunge, Curcuma longa Linn, and Myricaria bracteata. Two of these herbs (Lamiophlomis rotate; Curcuma longa Linn) are commonly used in different formulae of Chinese medicine. The objective of this study is to use an interdisciplinary approach to test the hypothesis that the formula and its components influence the process of CSTI.METHODS: In vivo models have been established in 30 rabbit ear pinnae and studied for: (1) blood flow velocity (BFV) which was affected by pressure of 21.2 kg/cm2 for 30 second over the local rabbit ear tissue; (2) edema formation of the closed soft tissue injury; (3) in vivo local temperature change.
RESULTS: The results of in vivo studies indicated that CSTI significantly increased the velocity of blood flow and increased edema formation within the control group. The PRP extracts for 5 hours significantly slowed down the BFV of CSTI in rabbit ears, markedly decreased the elevated edema level from the 3rd to the 5th day.
CONCLUSION: The ingredients contained in the formula have positive effects in healing CSTI and further study is worth exploring.
The leaves and twigs of Juniperus pingii var. wilsonii (Cupressaceae) smell aromatic and are traditionally used as the Tibetan medicine Xuba. Their essential oil obtained by ultrasonic-assisted hydrodistillation and volatiles collected by GC headspace technique were analyzed and compared by GC-MS. The analyses revealed the presence of thirty-nine components in the essential oil, representing 95.8% in content of the total oil, mainly including sabinene (22.6%), elemol (15.5%) and (-)-terpinen-4-ol (9.6%). Thirty-eight components accounting for 99.4% of the headspace volatiles were identified, mainly including sabinene (32.5%), β-pinene (21.9%) and α-thujene (10.3%). The compositions of the oil and headspace volatiles were quite similar, and twenty-five compounds identified were in common, which was 91.3% of the oil and 96.0% of the headspace volatiles in content. The essential oil could obviously inhibit Nitric oxide production in LPS-stimulated RAW 264.7 cells with no significant effect on cell viability, indicating its good anti-inflammatory activity.
OBJECTIVE: To systematically review evidence of primary outcomes from randomised controlled trials (RCTs) examining the effect of treatment strategies on quality of life (QoL) or psychosocial factors in individuals with knee osteoarthritis (OA). DESIGN: Systematic review with meta-analysis. DATA SOURCES: Medline, Embase, SPORTDiscus, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Web of Science were searched from inception to November 2017. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included RCTs investigating the effect of conservative interventions on QoL or psychosocial factors in individuals with knee OA. Only RCTs considering these outcomes as primary were included. RESULTS: Pooled data supported the use of exercise therapy compared with controls for improving health-related and knee-related QoL. There was limited evidence that a combined treatment of yoga, transcutaneous electrical stimulation and ultrasound may be effective in improving QoL. Limited evidence supported the use of cognitive behavioural therapies (with or without being combined with exercise therapy) for improving psychosocial factors such as self-efficacy, depression and psychological distress. SUMMARY/CONCLUSION: Exercise therapy (with or without being combined with other interventions) seems to be effective in improving health-related and knee-related QoL or psychosocial factors of individuals with knee OA. In addition, evidence supports the use of cognitive behavioural therapies (with or without exercise therapy) for improving psychosocial factors such as self-efficacy, depression and psychological distress in individuals with knee OA.

The Star Counting Test (SCT) has been developed to measure the regulatory function of attention. In a previous study it was shown that the SCT is suited for assessment of this attentional aspect with children. The present study concerns a more difficult version aimed at young adults. In the literature, the regulatory function of attention is increasingly stressed and it has been linked to working memory functioning. In order to further determine the validity of the SCT, performance was checked against two kinds of measures relating to working memory, i.e. Digit Span and Computational Span. These tasks both call for storage but differ in their claims on the processing component of working memory. Using confirmatory factor analysis substantial correlations were demonstrated with either of these measures. As expected, the correlations tended to rise with increasing demands on the processing component. Test scores were further compared with self-reported cognitive failures. No significant relation appeared to exist. The results are interpreted in terms of demands on the regulatory function of attention.

The scope of this paper is to analyze the self-declared symptoms and state of well-being of participants in the "Yoga and Promotion of Health" program, which consisted of hatha yoga lessons. It includes body exercises and breathing techniques, as well as ethical and philosophical content, administered to two groups of lecturers, workers and students of a public university in the State of Sao Paulo from August to December 2011 and March to June 2012. The participants filled out the adapted version of the Measure Yourself Medical Outcome Profile form at the beginning and end of the program. Of the 20 participants in Group 1, eight filled out the form and half of them reported the improvement of self-declared symptoms; as regards the state of well being, three of them felt they had improved. In Group 2, which also had 20 participants, nine completed the program and all of them reported improvements of self-declared symptoms and well-being. In conclusion, yoga is a mind-body practice which exerts an important therapeutic effect on most practitioners and also promotes health for the majority of them, expanding their capacity of self perception and self care. However, it should be noted that it doesn't achieve the same positive effect for all practitioners as some yoga traditions advocate.
Objective: The practice of yoga has been proven to have positive effects on reducing insomnia. Studies have also shown its effects on reducing climacteric symptoms. To date, however, no studies that evaluate the effects of yoga on postmenopausal women with a diagnosis of insomnia in a randomized clinical trial have been conducted. The aim of this study was to evaluate the effect of yoga practice on the physical and mental health and climacteric symptoms of postmenopausal women with a diagnosis of insomnia. Methods: Postmenopausal women not undergoing hormone therapy, who were 50 to 65 years old, who had an apnea-hypopnea index less than 15, and who had a diagnosis of insomnia were randomly assigned to one of three groups, as follows: control, passive stretching, and yoga. Questionnaires were administered before and 4 months after the intervention to evaluate quality of life, anxiety and depression symptoms, climacteric symptoms, insomnia severity, daytime sleepiness, and stress. The volunteers also underwent polysomnography. The study lasted 4 months. Results: There were 44 volunteers at the end of the study. When compared with the control group, the yoga group had significantly lower posttreatment scores for climacteric symptoms and insomnia severity and higher scores for quality of life and resistance phase of stress. The reduction in insomnia severity in the yoga group was significantly higher than that in the control and passive-stretching groups. Conclusions: This study showed that a specific sequence of yoga might be effective in reducing insomnia and menopausal symptoms as well as improving quality of life in postmenopausal women with insomnia.
Yoga has become a popular approach to improve emotional health. The aim of this review was to systematically assess and meta-analyze the effectiveness and safety of yoga for anxiety. Medline/PubMed, Scopus, the Cochrane Library, PsycINFO, and IndMED were searched through October 2016 for randomized controlled trials (RCTs) of yoga for individuals with anxiety disorders or elevated levels of anxiety. The primary outcomes were anxiety and remission rates, and secondary outcomes were depression, quality of life, and safety. Risk of bias was assessed using the Cochrane tool. Eight RCTs with 319 participants (mean age: 30.0-38.5 years) were included. Risk of selection bias was unclear for most RCTs. Meta-analyses revealed evidence for small short-term effects of yoga on anxiety compared to no treatment (standardized mean difference [SMD] = -0.43; 95% confidence interval [CI] = -0.74, -0.11; P = .008), and large effects compared to active comparators (SMD = -0.86; 95% CI = -1.56, -0.15; P = .02). Small effects on depression were found compared to no treatment (SMD = -0.35; 95% CI = -0.66, -0.04; P = .03). Effects were robust against potential methodological bias. No effects were found for patients with anxiety disorders diagnosed by Diagnostic and Statistical Manual criteria, only for patients diagnosed by other methods, and for individuals with elevated levels of anxiety without a formal diagnosis. Only three RCTs reported safety-related data but these indicated that yoga was not associated with increased injuries. In conclusion, yoga might be an effective and safe intervention for individuals with elevated levels of anxiety. There was inconclusive evidence for effects of yoga in anxiety disorders. More high-quality studies are needed and are warranted given these preliminary findings and plausible mechanisms of action.
