    This report describes the survey results of the scrap iron and steel recycling industries in Thailand and Indonesia. The purpose of this survey is to extract problems obstructing the scrap iron and steel recycling, to recognize the present situation and predict the future situation, and to examine the possibility of international cooperation. As a result of the survey, it was found that the quality of scrap collected in the domestic market is poor as it contains too many impurities for it to be utilized for the manufacture of many higher quality iron and steel products. The actual quantity of domestically collected scrap is too low to support the expected growth in demand in each nation. Current environmental management practices are largely concerned with the construction of wastewater treatment facilities and the extraction of furnace dust. However, the lack of enforcement of environmental regulations does not encourage companies to implement sound environmental practices. Neither government actively promotes and investigates iron and steel recycling in the domestic, commercial or industrial sectors. Collaboration with overseas nations having more advanced iron and steel industries could be helpful to the scrap recycling industry in both nations. 6 figs., 21 tabs.

    In order to promote steel slag re-utilization in developing countries, a possibility was presented for technical cooperation to India, Indonesia and Thailand upon putting the status of slag utilization in Japan into order. Blast furnace slag produced in Japan (having a re-utilization rate of 95%) is re-utilized and processed as cement aggregates and road beds, and converter slag as civil engineering materials and ores. Steel making slag (having a re-utilization rate of 80%) is re-utilized as road, processing and civil engineering materials. Since the steel making slag faces intensifying competition with ash made by incinerating construction and general wastes, it is important to improve its price competitiveness or mixed utilization with other materials. Re-utilization has not advanced to a recognizable level in developing countries because of having no difficulty for availability of lands for wastes. However, growth of full-scale steel industries and elevation in tendency of environment preservation now urge increase in the slag re-utilization rate. Required to achieve the goal would include wider use of re-utilization technologies, quality control on slag, joint use of facilities to produce re-utilization products, and governmental assistance on burdens of transportation cost. Assistance from Japan is expected to help meet these requirements. 25 figs., 31 tabs.

    This review briefly summarizes recent Tai Chi research on physical benefits including balance and muscle strength and psychological benefits including attentiveness, sleep and anxiety. Cardiovascular changes following Tai Chi include decreased heart rate and blood pressure, increased vagal activity and decreased cholesterol. Pain syndromes that have been affected include fibromyalgia, osteoarthritis and rheumatoid arthritis. Autoimmune and immune conditions recently researched and reviewed here include osteoporosis, diabetes and HIV. Methodological problems with this research include the variability in forms (series of postures) used across studies as well as the intensity of the Tai Chi schedule. Further, most of the studies are based on within group changes rather than attention control group comparisons. Nonetheless, significant clinical improvements have been noted.

    NEDO is positively implementing the training programs, in view of importance of training experts on (energy-saving and environmental conservation technologies), by inviting administrators and engineers from developing countries to educate them with Japan's pollution preventive techniques, administration procedures, energy-saving measures, and so on. In FY 1998, NEDO commissioned the International Center for Environment Technology Transfer to train administrators and engineers from Indonesia, the Philippines, Vietnam and Myanmar. This paper describes the proposals, based on the collected answers of the trainees to the questionnaires. The trainees were interested in all themes. About 40% of the trainees considered that the training period was short. Some trainees hoped the training course was held in summer. Difference in industrialization is reflected in difference in recognition and urgency of the environmental problems. Training was conducted by English and Vietnamese, but could be done without translators of Vietnamese. Preparation for the invitation needs a lot of works, and the course should be explained more thoroughly beforehand. It is regrettable that one trainee from Indonesia was late for the course. (NEDO)

    The activities implemented jointly (AIJ) is expected as global measures to reduce greenhouse gas (such as CO2) emission. In this report, the possibility of AIJ projects in developing countries was researched. The United Nations Framework Convention on Climate Change was signed by 155 countries in 1992. This convention parties approved AIJ projects for measures against global warming. The 1st Conference of the Parties (COPI) held in 1995 approved the pilot phase of AIJ by voluntary workers jointly with developing countries until the end of this century. The trend, level and future plan of energy conservation technologies were researched and analyzed for steelmaking, cement and electric power supply industries in both the Philippine and Thailand. The possibility of AIJ projects was studied by selecting several Japanese energy conservation technologies transferable to both countries. The same research was also carried out for forest as carbon absorption source. 5 refs., 23 figs., 58 tabs.

    In the last 2 decades, a growing body of research aimed at investigating the health benefits of Tai Chi in various chronic health conditions has been recognized in the literature. This article reviewed the history, the philosophy, and the evidence for the role of Tai Chi in a few selected chronic pain conditions. The ancient health art of Tai Chi contributes to chronic pain management in 3 major areas: adaptive exercise, mind-body interaction, and meditation. Trials examining the health benefit of Tai Chi in chronic pain conditions are mostly low quality. Only 5 pain conditions were reviewed: osteoarthritis, fibromyalgia, rheumatoid arthritis, low back pain, and headache. Of these, Tai Chi seems to be an effective intervention in osteoarthritis, low back pain, and fibromyalgia. The limitations of the Tai Chi study design and suggestions for the direction of future research are also discussed.

    Tai chi is a complex multicomponent mind-body exercise. Many studies have provided evidence that tai chi benefits patients with a variety of chronic disorders. This form of mind-body exercise enhances cardiovascular fitness, muscular strength, balance, and physical function and seems to be associated with reduced stress, anxiety, and depression and improved quality of life. Thus, despite certain limitations in the evidence, tai chi can be recommended to patients with osteoarthritis, rheumatoid arthritis, and fibromyalgia as a complementary and alternative medical approach.

    Inter-industry relations tables and energy statistics are combined for Asian countries for the preparation of energy analysis oriented inter-industry relations tables, which are used to metrically analyze Aisan nations' industrial structures and energy consumption structures for the ultimate purpose of grasping the magnitude of each industry's demand for energy. The tables prepared this year cover Korea, Indonesia, Thailand, and the Philippines. In Korea, the self-sufficiency rate of mineral fuels is low at 23.1%, which is due to its import of crude oil from abroad. It consumes 177.92-million tons (in terms of oil) of energy for its economic activities, with energy saving measures expected to work effectively here. Indonesia's mineral fuel self-sufficiency rate is high at 84.3% because it is an oil producing country. The energy it consumes for its economic activities is 179.37-million tons (in terms of oil), and energy saving measures will work effectively here. Thailand is a crude oil importing country. Its mineral fuel self-sufficiency rate is 33.4% and the energy its economic activities consume is 53.08-million tons (in terms of oil), and energy saving measures will work effectively in this country. The Philippines is a crude oil importing country and its mineral fuel self-sufficiency rate is as low as 4.8%. It consumes 22.71-million tons of energy (in terms of oil) for its economic activities, and energy-saving measures are expected to take effect here. (NEDO)

    Al-Turki, Faiza

    Healing is a multifaceted venture. Whereas many traditional cultures see healing as a journey that, by necessity, combines body, mind, and spirit, today's Western society frequently divides healing, relegating its parts to various experts--body to physicians, mind to psychologists, spirit to religions. Employing heuristic and alchemical hermeneutic methodologies, this thesis explores tai chi as a healing tool that bridges that division, exploring the following question: is it possible that the connection of body, mind, and spirit offered by tai chi is the very mechanism by which it facilitates healing? The cultural and historical context of tai chi is introduced, as well as research showing various Western views. A heuristic approach offers personal examples of the use of tai chi as a process partner, while a depth psychological lens informs the use of tai chi principles to guide moments of self-exploration and transformation in a therapeutic way.

    Balance function begins to decline from middle age on, and poor balance function increases the risk of fall and injury. Suitable exercise training may improve balance function and prevent accidental falls. The coordination of visual, proprioceptive, vestibular and musculoskeletal system is important to maintain balance. Balance function can be evaluated by functional balance testing and sensory organization testing. Tai Chi Chuan (TC) is a popular conditioning exercise in the Chinese community, and recent studies substantiate that TC is effective in balance function enhancement and falls prevention. In studies utilizing functional balance testing, TC may increase the duration of one-leg standing and the distance of functional reach. In studies utilizing sensory organization testing, TC improves static and dynamic balance, especially in more challenging sensory perturbed condition. Therefore, TC may be prescribed as an alternative exercise program for elderly subjects or balance-impaired patients. Participants can choose to perform a complete set of TC or selected movements according to their needs. In conclusion, TC may improve balance function and is appropriate for implementation in the community.

    Tai-chi chuan is popular worldwide especially in China. People practice tai-chi chuan daily with faith believing that they will be rewarded with health and varieties of other rewords. The Tai Chi Chuan Theory by Master Chang and the Tai Chi Chuan Theory by Master Wang are translated to be the baseline of the tai-chi chuan. The theory described in these two papers clearly shows that the tai-chi power source is the combination of the two antigravity forces distinction by each foot. The ying, yang and hollowed, solid discussed in the papers are the properties and body relationship of the two antigravity forces. The antigravity forces presented inside of body are as air to the balloon termed chi. However chi could be generated by any muscle pressing; only the antigravity forces from feet are called nature chi that has the maximum strength of the person. When a person is soft, as an infant the nature chi will fulfill entire body with no time and effort. The sequence forms were designed for deploying the nature chi in speed and power. The combination of chi and tai-chi form make tai chi chuan supreme than other kinds of martial art. In the training process chi massages whole body many time for a sequence form practice that stimulate all organs and could lead to cure body diseases, lose weight, postpone aging process, and remove the aging symptoms. For the people practicing in the park daily with proper guidance they will fulfill their wishes. Tai chi exercise could also apply to other sports as in dancing and golfing they are discussed at the end of the paper.

    Tai Chi Chuan (Tai Chi) is a Chinese traditional mind-body exercise and recently, it becomes popular worldwide. During the practice of Tai Chi, deep diaphragmatic breathing is integrated into body motions to achieve a harmonious balance between body and mind and to facilitate the flow of internal energy (Qi). Participants can choose to perform a complete set of Tai Chi or selected movements according to their needs. Previous research substantiates that Tai Chi has significant benefits to health promotion, and regularly practicing Tai Chi improves aerobic capacity, muscular strength, balance, health-related quality of life, and psychological well-being. Recent studies also prove that Tai Chi is safe and effective for patients with neurological diseases (e.g., stroke, Parkinson's disease, traumatic brain injury, multiple sclerosis, cognitive dysfunction), rheumatological disease (e.g., rheumatoid arthritis, ankylosing spondylitis, and fibromyalgia), orthopedic diseases (e.g., osteoarthritis, osteoporosis, low-back pain, and musculoskeletal disorder), cardiovascular diseases (e.g., acute myocardial infarction, coronary artery bypass grafting surgery, and heart failure), chronic obstructive pulmonary diseases, and breast cancers. Tai Chi is an aerobic exercise with mild-to-moderate intensity and is appropriate for implementation in the community. This paper reviews the existing literature on Tai Chi and introduces its health-promotion effect and the potential clinical applications.

    Full Text Available Exercise training is the cornerstone of rehabilitation for patients with cardiovascular disease (CVD. Although high-intensity exercise has significant cardiovascular benefits, light-to-moderate intensity aerobic exercise also offers health benefits. With lower-intensity workouts, patients may be able to exercise for longer periods of time and increase the acceptance of exercise, particularly in unfit and elderly patients. Tai Chi Chuan (Tai Chi is a traditional Chinese mind-body exercise. The exercise intensity of Tai Chi is light to moderate, depending on its training style, posture, and duration. Previous research has shown that Tai Chi enhances aerobic capacity, muscular strength, balance, and psychological well-being. Additionally, Tai Chi training has significant benefits for common cardiovascular risk factors, such as hypertension, diabetes mellitus, dyslipidemia, poor exercise capacity, endothelial dysfunction, and depression. Tai Chi is safe and effective in patients with acute myocardial infarction (AMI, coronary artery bypass grafting (CABG surgery, congestive heart failure (HF, and stroke. In conclusion, Tai Chi has significant benefits to patients with cardiovascular disease, and it may be prescribed as an alternative exercise program for selected patients with CVD.

    2016-11-01

    To summarize the evidence on the health benefits of tai chi. A literature review was conducted on the benefits of tai chi for 25 specific conditions, as well as for general health and fitness, to update a 2014 review of systematic reviews. Systematic reviews and recent clinical trials were assessed and organized into 5 different groups: evidence of benefit as excellent, good, fair, or preliminary, or evidence of no direct benefit. During the past 45 years more than 500 trials and 120 systematic reviews have been published on the health benefits of tai chi. Systematic reviews of tai chi for specific conditions indicate excellent evidence of benefit for preventing falls, osteoarthritis, Parkinson disease, rehabilitation for chronic obstructive pulmonary disease, and improving cognitive capacity in older adults. There is good evidence of benefit for depression, cardiac and stroke rehabilitation, and dementia. There is fair evidence of benefit for improving quality of life for cancer patients, fibromyalgia, hypertension, and osteoporosis. Current evidence indicates no direct benefit for diabetes, rheumatoid arthritis, or chronic heart failure. Systematic reviews of general health and fitness benefits show excellent evidence of benefit for improving balance and aerobic capacity in those with poor fitness. There is good evidence for increased strength in the lower limbs. There is fair evidence for increased well-being and improved sleep. There were no studies that found tai chi worsened a condition. A recent systematic review on the safety of tai chi found adverse events were typically minor and primarily musculoskeletal; no intervention-related serious adverse events have been reported. There is abundant evidence on the health and fitness effects of tai chi. Based on this, physicians can now offer evidence-based recommendations to their patients, noting that tai chi is still an area of active research, and patients should continue to receive medical follow-up for any

    Tai Chi, a systematic callisthenic exercise first developed in ancient China, involves a series of slow and rhythmic circular motions. It emphasises use of 'mind' or concentration to control breathing and circular body motions to facilitate flow of internal energy (i.e. 'qi') within the body. Normal flow of 'qi' is believed to be essential to sustain body homeostasis, ultimately leading to longevity. The effect of Tai Chi on balance and muscle strength in the elderly population has been reported; however, the effect of Tai Chi on dyspnoea, exercise capacity, pulmonary function and psychosocial status among people with chronic obstructive pulmonary disease (COPD) remains unclear. • To explore the effectiveness of Tai Chi in reducing dyspnoea and improving exercise capacity in people with COPD.• To determine the influence of Tai Chi on physiological and psychosocial functions among people with COPD. We searched the Cochrane Airways Group Specialised Register of trials (which included the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Allied and Complementary Medicine Database (AMED) and PsycINFO); handsearched respiratory journals and meeting abstracts; and searched Chinese medical databases including Wanfang Data, Chinese Medical Current Contents (CMCC), Chinese Biomedical Database (CBM), China Journal Net (CJN) and China Medical Academic Conference (CMAC), from inception to September 2015. We checked the reference lists of all primary studies and review articles for relevant additional references. We included randomised controlled trials (RCTs) comparing Tai Chi (Tai Chi alone or Tai Chi in addition to another intervention) versus control (usual care or another intervention identical to that used in the Tai Chi group) in people with COPD. Two independent review authors screened and selected studies. Two independent review authors extracted data from included

    Full Text Available Background. The present study aimed to evaluate and compare the effect of two different types of Tai Chi programs on the Functional Movement Screening (FMS in older adults. Methods. Ninety older adults (65.5 ± 4.6 years old who met the eligibility criteria were randomized into three different groups based on a ratio of 1 : 1 : 1: a traditional Tai Chi exercise (TTC, a simplified Tai Chi exercise (TCRT, or a control group (routine activity. The FMS consisted of the deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg rise, trunk stability push-up, and rotatory stability, which was used to measure physical function before the present study and after six months of Tai Chi interventions. Results. Seventy-nine participants completed the present study (control = 27, TTC = 23, and TCRT = 29. Significant improvement on the FMS tests between the baseline and after the six-month intervention was observed in both Tai Chi programs, whereas no significant improvement was observed in the control group. In addition, participants in the TCRT group demonstrated greater improvement than those in the TTC group. Conclusions. The TCRT is more effective in improving the physical function in older adults when compared to the traditional Tai Chi modality, particularly for improving balance.

    Tai Ji Quan, developed as a martial art, has traditionally served multiple purposes, including self-defense, competition/performance, and health promotion. With respect to health, the benefits historically and anecdotally associated with Tai Ji Quan are now being supported by scientific and clinical research, with mounting evidence indicating its potential value in preventing and managing various diseases and improving well-being and quality of life in middle-aged and older adults. The research findings produced to date have both public health significance and clinical relevance. However, because of its roots in the martial arts, transforming traditional Tai Ji Quan movements and training approaches into contemporary therapeutic programs and functional applications is needed to maximize its ultimate utility. This paper addresses this issue by introducing Tai Ji Quan: Moving for Better Balance , a functional therapy that involves the use of Tai Ji Quan principles and Yang-style-based movements to form an innovative, contemporary therapeutic approach that integrates motor, sensory, and cognitive components to improve postural control, gait, and mobility for older adults and those who have neurodegenerative movement impairments. It provides a synergy of traditional and contemporary Tai Ji Quan practice with the ultimate goal of improving balance and gait, enhancing performance of daily functional tasks, and reducing incidence of falls among older adults.

    It is decided in the COP4 that the concrete schemes for the (Kyoto Mechanism) should be boiled down towards the end of 2000. Of the many outstanding issues concerned, those related to the clean development mechanism (CDM) involve a number of problems awaiting solution. In particular, setting the baselines for amounts of the greenhouse effect gas emissions in projects not existing, which are essential for identifying reduced amounts of emissions (or credits), poses serious difficulty because of wide arbitrariness involved in the methodology. Therefore, (standardization) of the procedures is demanded for the accurate identification. In actuality, however, no methodology has been established as to what methods will be possibly applicable to widely diversified types of projects. This workshop, therefore, has focused the discussions on the (baseline problems), expecting to serve as a trigger for the future directions by presenting international researches and promoting the discussions thereon to deepen recognition of these problems, where the AIJ experiences have served as one of the bases.

    The purpose of the survey is to promote the international research cooperation projects from the survey stage, via demonstration research stage to the diffusion stage. Field surveys have been conducted to find out the needs of energy saving and environmental technology for the efficient consumption of petroleum in the developing countries with mass-consumption of petroleum in the future. The survey was conducted in the Philippines in the FY 1996. Next developing themes were proposed. The first theme was developing method of sugar plant. The magnesia method has been developed as a basic technology for cleaning sugar solution process instead of using lime. By the recycling method, the waste cake amount can be remarkably reduced. The second theme was electron beam exhaust gas treatment by a dry method of simultaneous desulfurization and denitrification of high concentration SOx and NOx in the fertilizer production plants. The third theme was the energy saving technology for SOx reduction of heating furnace for iron-steel by using an ultra energy saving-type regenerative burner. The last theme was chlorine bypass technology in cement industry, which would become an advanced technology development for the use of chlorine containing fuels in the near future. 40 refs., 36 figs., 79 tabs.

    The project aims at energy saving and CO2 emission reduction for a clinker cooling system (CCS), and a demonstration test was conducted at a demonstration cement plant in Indonesia. The plant started operation using the new CCS aiming for the enhancement of cooling and heat recovery efficiency. The actually achieved heat recovery efficiency attributable to the adoption of the new CCS was 60.8% against the target of 68%, this meaning an improvement of 8% over the value recorded prior to the new CCS adoption. As for increase in recovered heat due to heat recovery efficiency improvement of the CCS itself, it was 31kcal/kg-clinker. The heat reduction rate throughout the system thanks to the new CCS was 40kcal/kg-clinker. The kiln secondary air temperature increased for improved burner combustion performance for a rise of the clinker burning degree to 12kcal/kg in terms of calorie, and thus a reduction of 52kcal/kg-clinker in total was achieved. No mechanical trouble was reported with the new CCS. Investigations were conducted into cement supply/demand and technological trends in Indonesia, Vietnam, and China. Learnings from the investigation of German cement making technologies were fully utilized in the designing of the new system. (NEDO)

    A dissemination plan was decided on concerning an energy-related database, which has been prepared in the eight countries including Japan in the Asian Pacific region since fiscal 1993. The database is so designed that the energy-related data of the eight countries are retained equally by each country and that the data of all these countries are readily made available in each of these counties in the same manner as retrieving the data of its own. It is necessary that each country establishes a system of amassing data of its own and collecting the data continuously as well as renewing the data mutually with the other countries. The disseminating/enlightening measures of the database were extracted from such viewpoints as enhancing the recognition level, educating/enlightening the usage, teaching the operation method, and customizing the NEDO-DB. In addition, a plan was prepared in which organizations/institutions, as the object of the dissemination and enlightenment in each country, were classified into four groups based on the relation to their counterpart and on the possibility of the database utilization, with a schedule made for each group as to the implementation of each of the disseminating/enlightening measures.

    Field research was made for oil saving in Thailand. To promote energy saving in a textile industry as main export industry, its motivation for production stuff is essential in business improvement. Proposal for work improvement, supply system of bonuses, and small-group activity are effective. Management of an energy consumption rate is essential in business management. Use of efficient waste water treatment equipment is also one of the issues. In food factories, various scopes for improvement are still found by mass/heat balance analysis in production process. As an example, a large amount of water is consumed in vain for washing raw rice in a rice powder factory, and separation of SS precipitate from waste water should be improved. Because of lagoon treatment, an effluent standard is not achieved in spite of consumption of wasteful aeration power. This treatment is reasonable because of its scale and site, although the standard can be achieved by activated sludge method. Reconsideration of the standard is also necessary based on a local total BOD load capacity. The profitability of a methane fermentation method should be examined. 72 figs., 95 tabs.

    For the purpose of contributing to the economic growth and the global environmental protection in the Asian area, an investigation was carried out into energy conservation technology and environmental protection technology in the chemical industry of Japan. Measures for energy conservation are shifting from those which do not cost so much such as reduction in excess air rate of the heating furnace, and reduction in reflux ratio of the distillation tower to those with equipment investment such as waste heat recovery of the heating furnace and waste heat recovery of the distillation tower. In the 1980s, the utilization of low temperature waste heat by absorption type refrigerator and heat pump was promoted and the energy utilization efficiency by computer control was enhanced. Concerning environmental measures, the following were carried out: installation of the flue gas desulfurization device and reconstruction of high-rise stack, reduction of NOx by combustion control, smoke/dust disposal of electrostatic precipitator, combustion of hydrocarbon causing photochemical oxidant, catalytic oxidation, condensation, treatment by activated carbon, activated sludge treatment for BOD/COD, diaphragm process for dimethylmercury, ion exchange resin process, etc. 21 refs., 29 figs., 27 tabs.

    This paper makes an analysis on the characteristics of R and D concerning Australia, one of the core nations in the cooperation, on the basis of the idea that 'establishment of new comparative superiority through cooperation' can be realized by joint work among Japan, Australia and Asian nations. In Australia, it was found that R and D was often promoted through a new idea obtained by recruiting heterogeneous persons and communicating mutually internally. It was also found that in Australia an affinity exists to such persons of different nature. Accordingly, Australia was presumably quite suitable for the place to bring up the persons of developing nations. On the basis of these analytical results, proposal was made to promote three programs; namely, preparation of a data base for R and D organizations and the staff, commencement of a partnership program, and opening of a needs searching conference.

    Developing countries have no sufficient basic data for the analysis of meteorological conditions including wind characteristics, and there are problems in adopting simulation models there. Accordingly, the revision/development of simulation models were conducted, considering characteristics of models to predict wind characteristics from topographical/geographical aspects and widely meteorological aspect in Myanmar. At the same time, the mean wind velocity distribution chart for Myanmar was drawn up by observing wind characteristics domestically in Myanmar, by comparing the predicted results using the above-mentioned models and the measured data, and by verifying the simulation results. The items for development are as follows: (1) To make simulation models for wind characteristics in the whole Myanmar based on the information obtained from the meteorological observation system for prediction of the mean wind velocity. Also to verify the simulational results using the measured data on wind characteristics at specified points. (2) To conduct the developmental work under a research system jointly with the counterpart and to produce favorable results as an international joint research.

    On-site researches are conducted to study the possibility of a model business using energy-saving and environment preservation technologies of Japan and Indonesia. At textile plants, the management of heat and water in the dyeing and finishing processes is found inadequate, with great quantities of heat left uncared-for in medium- and low-temperature wastewater. An energy-saving proposition is submitted in which solar energy and absorption-type refrigerators are combined. Instrumentation and management also require improvement. At nitrogenous and phosphatic fertilizer plants, the energy consumption rate is found aggravated by degradation of facilities, and continued research and further analysis are necessary before working out energy-saving policies for them. At urea fertilizer plants, though it is not easy to modernize the manufacturing processes, energy-saving and environment preserving efforts are under way within the bounds of capability. Their energy consumption rate is high because of frequent shut-downs. It is necessary to detect an anomaly at its early stage and to introduce backup systems for the elimination of erroneous operations. Operating conditions need to be analyzed for validity. At melamine manufacturing plants, process drainage is allowed into the river without any treatment contaminating the water with products of melamine hydrolysis. Short-term and long-term solutions are suggested. (NEDO)

    For global scale measures to be taken for environmental protection, it becomes more and more important in the future to positively transfer and spread energy conservation technologies of Japan to overseas countries. Especially, it is effective for both economic growth in the Asian region and global environmental protection to transfer technologies which the oil refining industry has been developing and accumulating. Energy conservation in the oil refining industry means the energy conservation by strengthening the operational control at the first and second oil crises in the first stage, the energy conservation in the second stage which was accompanied by small and medium scale plant/equipment investments during several years after the first stage, and the energy conservation in the third stage which was accompanied by large scale investments from the first half of the 1980s to the present, resulting in improvement of 40% over before the first oil crisis. As to environmental protection measures, measures to reduce waste from oil refinery against air pollution and water pollution were prepared by the first half of the 1970s, and technologies were established of waste water treatment, flue gas desulfurization and denitrification. A lot of facilities for improvement of product quality and for low pollution were installed. In addition to environmental technologies, also in other industries, there were seen the heightening of thermal efficiency of kiln and thermal efficiency of cooling technique of clinker cooler in the cement industry and the improvement of productivity in the paper/pulp industry. 360 figs., 62 tabs.

    The field research of oil conservation was conducted in developing countries, in particular, Vietnam where a steep increase in oil consumption is anticipated in the future. Energy conservation is the most effective direct measures to control combustion of fossil fuels, and an important issue to be promoted by all countries in the world to prevent global warming and reserve energy resources. In fiscal 1994, main industries in the northern part of Vietnam were researched. In fiscal 1995, the report meeting of plant survey results in the northern part and the technical seminar of energy-saving in industrial field were held, and plants around Ho Chi Minh City in the southern part of Vietnam were researched. Although Vietnam has recently acquired membership in ASEAN and is undergoing dramatic economic growth, has many problems in environmental measures. Japan has top-ranking results on energy-saving in industrial field, and the transfer of such superior technologies and techniques will greatly contribute to resource and global warming problems as well as pollution control measures in Vietnam. 13 refs., 25 figs., 26 tabs.

    The Conference on the Policies and Measures of Climate Change Mitigation was held in Tokyo on January 28, 1997, with participation in the conference from governments, research institutes, industrial circles, NGO, etc. of ten countries including Japan. In the session `technology transfer,` presentations were made on `the current status of the technology transfer, and the expectation and requests` by Australia and Japan which provide technology and by China which receives technology. As a whole, every country recognized importance of technology transfer of both hardware and software, private sectors` taking leadership, the use of international organizations dealing with fund supply and credit guarantee. In the session `tradable permits/quotas,` Dr. A. Haspel, U.S. Department of Energy reported the structure and effect of U.S. tradable emission permits on sulfur dioxide from thermal power plants, and proposed tradable emission permits against greenhouse effect gas. The proposal needs to be further studied and discussed, and it was regarded as too early to include the proposal in the protocol to be conducted at COP3

    Full Text Available The relationship between physical activity (PA and cognition has received much attention recently. While evidence of improved cognition following PA has consistently been observed, the majority of studies have spotlighted aerobic exercise and the effects of other modes of PA, such as Tai Ji Quan, on cognition have received limited attention. This article provides a brief review of the literature concerning the influence of Tai Ji Quan on cognition in older adults, including those with intact cognition and those with cognitive impairment. In addition, this review proposes potential mechanisms (cardiovascular fitness, motor fitness, movement coordination, social interaction, and meditation statuses as well brain structure and function evaluated from a neuroimaging perspective that may explain the Tai Ji Quan–cognition relationship. Finally, we present suggestions for future research. In conclusion, Tai Ji Quan, with its multi-faceted characteristics, shows promise as a mode of PA for enhancing cognition, as well as brain health, in older adults. Based on the findings in this review, further exploration of the effects of Tai Ji Quan on cognition in older adults is warranted.

    In order to maintain stable upright stance, the postural control system must account for the continuous perturbations to the body's center-of-mass including those caused by spontaneous respiration. Both aging and disease increase "posturo-respiratory synchronization;" which reflects the degree to which respiration affects postural sway fluctuations over time. Tai Chi training emphasizes the coordination of respiration and bodily movements and may therefore optimize the functional interaction between these two systems. The purpose of the project was to examine the effect of Tai Chi training on the interaction between respiration and postural control in older adults. We hypothesized that Tai Chi training would improve the ability of the postural control system to compensate for respiratory perturbations and thus, reduce posturo-respiratory synchronization. Participants were recruited from supportive housing facilities and randomized to a 12-week Tai Chi intervention (n=28; 86 ± 5 yrs) or educational-control program (n=34, 85 ± 6 yrs). Standing postural sway and respiration were simultaneously recorded with a force plate and respiratory belt under eyes-open and eyes-closed conditions. Posturo-respiratory synchronization was determined by quantifying the variation of the phase relationship between the dominant oscillatory mode of respiration and corresponding oscillations within postural sway. Groups were similar in age, gender distribution, height, body mass, and intervention compliance. Neither intervention altered average sway speed, sway magnitude or respiratory rate. As compared to the education-control group, however, Tai Chi training reduced posturo-respiratory synchronization when standing with eyes open or closed (ppostural control or respiration, yet reduced the coupling between respiration and postural control. The beneficial effects of Tai Chi training may therefore stem in part from optimization of this multi-system interaction. Copyright © 2015

  16. Ezra Pound and Du Fu: Gazing at Mt. Tai

    Full Text Available Confined to a six-by-six-foot outdoor steel cage, Ezra Pound saw a series of mountain hills from a few miles to the east of Pisa. The poet compared one of these small 800-metre hills to the sacred Chinese Mt. Tai, which becomes the most common geographical name in The Pisan Cantos. Pound’s poetic summoning of this particular mountain is related to the fact that Mt. Tai is historically and culturally connected to the philosophy of Confucius, who personally ascended the mountain several times. Pound, as a devout Confucian disciple, closely follows the philosophical doctrines and attempts to mentally trace the footsteps of Confucius. This paper will argue how Pound’s poetic evocation of the mountain shares a striking similarity to an eighth-century Chinese poem called “Gazing at Mt. Tai,” which was written by the famous literatus - Du Fu 杜甫(712 – 770 . In spite of living in two completely different eras and countries, Pound’s and Du Fu’s reference to Mt. Tai demonstrates the confluence of their poetic spirits. Neither of them ascended mountain personally. They instead made use of their poetic imagination to follow the paths of Confucius and perceived the mountain as an earthly paradise, one which represents tranquillity and serenity away from the moral and physical corruption of the external world.

    Rheumatologic diseases (e.g., fibromyalgia, osteoarthritis, and rheumatoid arthritis) consist of a complex interplay between biologic and psychological aspects, resulting in therapeutically challenging chronic conditions to control. Encouraging evidence suggests that Tai Chi, a multi-component Chinese mind-body exercise, has multiple benefits for patients with a variety of chronic disorders, particularly those with musculoskeletal conditions. Thus, Tai Chi may modulate complex factors and improve health outcomes in patients with chronic rheumatologic conditions. As a form of physical exercise, Tai Chi enhances cardiovascular fitness, muscular strength, balance, and physical function. It also appears to be associated with reduced stress, anxiety, and depression, as well as improved quality of life. Thus, Tai Chi can be safely recommended to patients with fibromyalgia, osteoarthritis, and rheumatoid arthritis as a complementary and alternative medical approach to improve patient well-being. This review highlights the current body of knowledge about the role of this ancient Chinese mind-body medicine as an effective treatment of rheumatologic diseases to better inform clinical decision-making for our patients.

    Background Patients with Parkinson's disease have substantially impaired balance, leading to diminished functional ability and an increased risk of falling. Although exercise is routinely encouraged by health care providers, few programs have been proven effective. Methods We conducted a randomized, controlled trial to determine whether a tailored tai chi program could improve postural control in patients with idiopathic Parkinson's disease. We randomly assigned 195 patients with stage 1 to 4 disease on the Hoehn and Yahr staging scale (which ranges from 1 to 5, with higher stages indicating more severe disease) to one of three groups: tai chi, resistance training, or stretching. The patients participated in 60-minute exercise sessions twice weekly for 24 weeks. The primary outcomes were changes from baseline in the limits-of-stability test (maximum excursion and directional control; range, 0 to 100%). Secondary outcomes included measures of gait and strength, scores on functional-reach and timed up-and-go tests, motor scores on the Unified Parkinson's Disease Rating Scale, and number of falls. Results The tai chi group performed consistently better than the resistance-training and stretching groups in maximum excursion (between-group difference in the change from baseline, 5.55 percentage points; 95% confidence interval [CI], 1.12 to 9.97; and 11.98 percentage points; 95% CI, 7.21 to 16.74, respectively) and in directional control (10.45 percentage points; 95% CI, 3.89 to 17.00; and 11.38 percentage points; 95% CI, 5.50 to 17.27, respectively). The tai chi group also performed better than the stretching group in all secondary outcomes and outperformed the resistance-training group in stride length and functional reach. Tai chi lowered the incidence of falls as compared with stretching but not as compared with resistance training. The effects of tai chi training were maintained at 3 months after the intervention. No serious adverse events were observed. Conclusions

    Previous research has suggested that tai chi offers a therapeutic benefit in patients with fibromyalgia. We conducted a single-blind, randomized trial of classic Yang-style tai chi as compared with a control intervention consisting of wellness education and stretching for the treatment of fibromyalgia (defined by American College of Rheumatology 1990 criteria). Sessions lasted 60 minutes each and took place twice a week for 12 weeks for each of the study groups. The primary end point was a change in the Fibromyalgia Impact Questionnaire (FIQ) score (ranging from 0 to 100, with higher scores indicating more severe symptoms) at the end of 12 weeks. Secondary end points included summary scores on the physical and mental components of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). All assessments were repeated at 24 weeks to test the durability of the response. Of the 66 randomly assigned patients, the 33 in the tai chi group had clinically important improvements in the FIQ total score and quality of life. Mean (+/-SD) baseline and 12-week FIQ scores for the tai chi group were 62.9+/-15.5 and 35.1+/-18.8, respectively, versus 68.0+/-11 and 58.6+/-17.6, respectively, for the control group (change from baseline in the tai chi group vs. change from baseline in the control group, -18.4 points; Ptai chi group versus 28.0+/-7.8 and 29.4+/-7.4 for the control group (between-group difference, 7.1 points; P=0.001), and the mental-component scores were 42.6+/-12.2 and 50.3+/-10.2 for the tai chi group versus 37.8+/-10.5 and 39.4+/-11.9 for the control group (between-group difference, 6.1 points; P=0.03). Improvements were maintained at 24 weeks (between-group difference in the FIQ score, -18.3 points; PTai chi may be a useful treatment for fibromyalgia and merits long-term study in larger study populations.

    To examine the effects of long-term Tai Ji Quan (Chinnese Traditional Exercise) on automatic nervous modulation in the elders. The 18 subjects from Tai Ji Quan exercise class in Liaoning University of Retired Veteran Cadres were assigned into long-term Tai Ji Quan exercise group including 10 subjects and novice group including 8 subjects. Electrocardiography, respiratory and blood pressure data were collected on the following time points: at rest before Tai Ji Qhuan exercise and 30 min or 60 min after Tai Ji Quan exercise. The subjects at rest state in the long-term Tai Ji Quan exercise group showed higher than the subjects in the novice group in resperitory rate (RR), standard deviations of normal to normal intervals (SDNN), total power (TP), low frequency power (LFP), high frequency power (HFP), normalized high frequency power (nHFP), but lower in LFP/HFP, systolic and diastolic blood pressure, and heart rate. At rest state the respiratory rate of subjects in long-term Tai Ji Quan exercise group was significantly lower than the novices. After Tai Ji Quan exercise, TP, nHFP, LFP/HFP, heart rate and systolic pressure showed significantly changes, and the change level of Tai Ji Quan on these indices was larger in Tai Ji Quan exercise group than that in the novice group. Long-term Tai Ji Quan exercise can improve vagal modulations, and tend to reduce the sympathetic modulations.

    Push Hand is an advanced training technique for the Yang-style old frame 108 forms Tai Chi Chuan. It is performed by two practitioners. To clarify how people use forces during Push Hand training, it is important to review the ground reaction force (GRF). Here, we quantify the characteristics of the GRF during Push Hand training. Kinematic data and GRF data from 10 Tai Chi Chuan practitioners (29.9 ± 7.87 years) were synchronously recorded using a three-dimensional motion analysis system (200 frames · s(-1)) and three-dimensional force plates (1000 Hz). The resultant GRF for both feet for the 0%, 50% and 100% phases of attack and defence were compared to body weight using a paired-samples t-test. The differences in the resultant GRF between the 0%, 50% and 100% phases of attack and defence were tested by one-way repeated-measures ANOVA. The significance level was set to 0.05. The total resultant GRF was almost equal to the participant's body weight in push hand. This result was consistent throughout the entire push hand process. Our results revealed that the GRF was comparable to the body weight, implying that practitioners do not push or resist their opponents during the push hand process.

    Full Text Available Abstract Tai Chi Quan (Tai Chi, a traditional Chinese martial art, has become increasingly popular in western countries. Tai Chi integrates deep diaphragmatic breathing with body movements to achieve a harmonious balance between the body and mind, which facilitates the flow of internal energy (Qi. An increasing number of studies have reported that Tai Chi significantly benefits aerobic capacity, muscular strength, balance, and psychological well-being. In addition, Tai Chi offers unique advantages for physical fitness and the treatment of chronic diseases. This paper reviews the existing literatures on Tai Chi, introduces its health-promotion effects and the potential clinical applications, and summarizes recent studies that prove Tai Chi is safe and effective for patients with neurological diseases, rheumatological diseases, musculoskeletal diseases, cardiovascular diseases, chronic obstructive pulmonary diseases, and cancers. After reviewing the literatures in this field, we conclude that the long-term results of practicing Tai Chi may benefit the cardiovascular system, motor system, respiratory system, and nervous system. However, the potential role and mechanism of Tai Chi has not yet been determined. Further studies with long follow-up periods are necessary to meet the standards of clinical applications.

    Understanding the genetic mechanisms underlying carbohydrate metabolism can promote the development of biotechnological advances in fruit plants. The flesh tomato fruit represents an ideal system for examining the role of sucrose cleavage enzymes in fruit development, and wild tomato species differing in storage sugars serve as an excellent research material for this purpose. Plant vacuolar invertase is a key enzyme of sucrose metabolism in the sink organs. In the present study, we identified complete gene sequences encoding the TAI vacuolar invertase in 11 wild and one cultivated tomato accessions of the Solanum section Lycopersicon. The average level of interspecific polymorphism in TAI genes was 8.58%; however, in the green-fruited tomatoes, the TAI genes contained 100 times more SNPs than those in the red-fruited accessions. The TAI proteins demonstrated 8% variability, whereas the red-fruited species had none. A TAI-based phylogenetic tree revealed two main clusters containing self-compatible and self-incompatible species, which concurs with the previous crossability-based division and demonstrates that the TAI genes reflect the evolutionary relationships between the red- and green-fruited tomatoes. Furthermore, we detected differential expression patterns of the TAI genes in the fruits of wild and cultivated tomatoes, which corresponded to sugar composition. The polymorphism analysis of the TAI acid invertases of Solanum section Lycopersicon species will contribute to the understanding of the genetic potential of TAI genes to impact tomato breeding through genetic engineering of the carbohydrate composition in the fruit.

    Full Text Available BACKGROUND: The safety and health benefits of Tai Chi mind-body exercise has been documented in a large number of clinical studies focused on specific diseases and health conditions. The objective of this systematic review is to more comprehensively summarize the evidence base of clinical studies of Tai Chi for healthcare. METHODS AND FINDINGS: We searched for all types of clinical studies on Tai chi in PubMed, the Cochrane Library and four major Chinese electronic databases from their inception to July 2013. Data were analyzed using SPSS17.0 software. A total of 507 studies published between 1958 and 2013 were identified, including 43 (8.3% systematic reviews of clinical studies, 255 (50.3% randomized clinical trials, 90 (17.8% non-randomized controlled clinical studies, 115 (22.7% case series and 4 (0.8% case reports. The top 10 diseases/conditions was hypertension, diabetes, osteoarthritis, osteoporosis or osteopenia, breast cancer, heart failure, chronic obstructive pulmonary disease, coronary heart disease, schizophrenia, and depression. Many healthy participants practiced Tai Chi for the purpose of health promotion or preservation. Yang style Tai Chi was the most popular, and Tai Chi was frequently practiced two to three 1-hour sessions per week for 12 weeks. Tai Chi was used alone in more than half of the studies (58.6%, while in other studies Tai Chi was applied in combination with other therapies including medications, health education and other physical therapies. The majority of studies (94.1% reported positive effects of Tai Chi, 5.1% studies reported uncertain effects and 0.8% studies reported negative effects. No serious adverse events related to Tai Chi were reported. CONCLUSIONS: The quantity and evidence base of clinical studies on Tai Chi is substantial. However, there is a wide variation in Tai Chi intervention studied and the reporting of Tai Chi intervention needs to be improved. Further well-designed and reported studies

    As a part of development of the energy conservation technology database, revision was made on 'Directory of Energy Conservation Technology in Japan' which was published to present the energy conservation technology of the Japanese energy-intensive industry to Asian countries in fiscal 1996. The previous directory was composed of 307 technical items, and 126 items among them were deleted and new 63 items were added through this revision. The technologies with energy conservation effects more than 10% were mainly selected by knowledge of the industrial members of the committee and other specialists. The energy conservation effect widely ranges from low-level one to high-level one, and the number of all the energy conservation technologies is enormous. Consequently, it should be considered that the applicable extent of the energy conservation technologies is dependent on the energy cost or economical situation of Japan and developing countries.

    Indonesia is the biggest iron steel producing country in the ASEAN countries. Most of the production is produced by the electric furnace method in which iron steel scrap is used as a material. However, an energy saving measure in this method, the electric furnace scrap preheater using flue gas, has not yet been spread on a full scale. This R and D is aimed at developing jointly with Indonesia an electric furnace scrap preheater for medium/small size electric furnaces which are adoptable to the present iron making situation in Indonesia and installing it to the electric furnace of the iron making plant in Indonesia for a demonstrative study on energy saving, etc. Spread/expansion of the electric furnace scrap preheater which is an excellent energy saving system targeted expansion of energy saving technology not only of Indonesia, but of ASEAN countries and Japan. In this fiscal year, remodeling of part of the system was made by change of flue gas flow for increasing the energy saving effect, and at the same time, a research study was made of a scrap reheater effective as a total system. Moreover, the paper investigated technical data/information in Japan and overseas. 3 figs., 9 tabs.

    Full Text Available It is important to identify effective non-pharmacological alternatives to stimulant medications that reduce symptoms of attention deficit hyperactivity disorder (ADHD. In this study of healthy young adults, we measured the effects of training in tai chi, which involves mindful attention to the body during movement. Using a non-randomized, controlled, parallel design, students in a 15-week introductory tai chi course (n=28 and control participants (n=44 were tested for ADHD indicators and cognitive function at three points over the course of the 15 weeks. The tai chi students' self-report of attention, but not hyperactivity-impulsivity, improved compared to controls. At baseline, inattention correlated positively with reaction time variability in an affective go/no-go task across all participants, and improvements in attention correlated with reductions in reaction time variability across the tai chi students. Affective bias changed in the tai chi students, as reaction times to positive- and negative-valenced words equalized over time. These results converge to suggest that tai chi training may help improve attention in healthy young adults. Further studies are needed to confirm these results and to evaluate tai chi as therapy for individuals with ADHD.

    A substantial number of individuals with Parkinson's disease exhibit debilitating non-motor symptoms that decrease quality of life. To date, few treatment options exist for the non-motor symptomatology related to Parkinson's disease. The goal of this pilot investigation was to determine the effects of Tai Chi exercise on the non-motor symptomology in Parkinson's disease. Twenty-one individuals with Parkinson's disease were enrolled in a Tai Chi intervention (n=15) or a noncontact control group (n=6). Participants assigned to Tai Chi participated in 60-minute Tai Chi sessions three times per week, for 16 weeks. Pre and post measures included indices of cognitive-executive function including visuomotor tracking and attention, selective attention, working memory, inhibition, processing speed and task switching. Additionally, all participants were evaluated on the Parkinson's disease Questionnaire-39 and Tinetti's Falls Efficacy Scale. Results indicated that the Tai Chi training group had significantly better scores following the intervention than the control group on the Parkinson's disease Questionnaire-39 total score as well as the emotional well-being sub score. Trends for improvement were noted for the Tai Chi group on Digits Backwards, Tinetti's Falls Efficacy Scale, and the activities of daily living and communication sub scores of the Parkinson's disease Questionnaire-39. This research provides initial data that supports future studies to definitively establish efficacy of Tai Chi to improve non-motor features of Parkinson's disease.

    Activity participation has a positive impact on both quantity and quality of life (QOL). Regular participations in physical, social, and cultural activities are associated with successful aging. There is considerable evidence that Tai Chi has positive health benefits; physical, psychosocial and therapeutic. Furthermore, Tai Chi does not only consist of a physical component, but also sociocultural, meditative components that are believed to contribute to overall well-being. This chapter describes the benefits of Tai Chi exercise for the older adults, particularly in terms of the psychosocial aspect. The perceived meanings, associated values and well-being, as well as the impact on QOL, of Tai Chi practice among the older adults in Hong Kong are also discussed. Tai Chi exercise is chosen by the elderly participants for its gentle and soft movements. Besides the physical aspect, the benefits they describe include lifestyle issues, as well as psychological and social benefits. Evidence points out that the improvements in physical and mental health through the practice of Tai Chi among the older adults are related to their perceived level of QOL. Findings from numerous studies support the belief that the practice of Tai Chi has multiple benefits to practitioners that are not only physical in nature. It is recommended as a strategy to promote successful aging.

  3. Tai chi for health benefits in patients with multiple sclerosis: A systematic review.

    Full Text Available The aim of this systematic review was to evaluate the existing evidence on the effectiveness and safety of Tai chi, which is critical to provide guidelines for clinicians to improve symptomatic management in patients with multiple sclerosis (MS. After performing electronic and manual searches of many sources, ten relevant peer-reviewed studies that met the inclusion criteria were retrieved. The existing evidence supports the effectiveness of Tai chi on improving quality of life (QOL and functional balance in MS patients. A small number of these studies also reported the positive effect of Tai chi on flexibility, leg strength, gait, and pain. The effect of Tai chi on fatigue is inconsistent across studies. Although the findings demonstrate beneficial effects on improving outcome measures, especially for functional balance and QOL improvements, a conclusive claim should be made carefully for reasons such as methodological flaws, small sample size, lack of specific-disease instruments, unclear description of Tai chi protocol, unreported safety of Tai chi, and insufficient follow-up as documented by the existing literature. Future research should recruit a larger number of participants and utilize the experimental design with a long-term follow-up to ascertain the benefits of Tai chi for MS patients.

    2009-05-01

    Full Text Available Abstract Background Low back pain persisting for longer than 3 months is a common and costly condition for which many current treatments have low-moderate success rates at best. Exercise is among the more successful treatments for this condition, however, the type and dosage of exercise that elicits the best results is not clearly defined. Tai chi is a gentle form of low intensity exercise that uses controlled movements in combination with relaxation techniques and is currently used as a safe form of exercise for people suffering from other chronic pain conditions such as arthritis. To date, there has been no scientific evaluation of tai chi as an intervention for people with back pain. Thus the aim of this study will be to examine the effects of a tai chi exercise program on pain and disability in people with long-term low back pain. Methods and design The study will recruit 160 healthy individuals from the community setting to be randomised to either a tai chi intervention group or a wait-list control group. Individuals in the tai chi group will attend 2 tai chi sessions (40 minutes/week for 8 weeks followed by 1 tai chi session/week for 2 weeks. The wait-list control will continue their usual health care practices and have the opportunity to participate in the tai chi program once they have completed the follow-up assessments. The primary outcome will be bothersomeness of back symptoms measured with a 0–10 numerical rating scale. Secondary outcomes include, self-reports of pain-related disability, health-related quality of life and global perceived effect of treatment. Statistical analysis of primary and secondary outcomes will be based on the intention to treat principle. Linear mixed models will be used to test for the effect of treatment on outcome at 10 weeks follow up. This trial has received ethics approval from The University of Sydney Human Research Ethics Committee. HREC Approval No.10452 Discussion This study will be the first

    2015-03-01

    Previous research has documented the beneficial effect of Tai Chi, but most of the studies focused on elders and patients with specific health conditions. The aim of the study was to test whether Tai Chi can help to improve self-concept in adolescents with a longitudinal study. The sample comprised 160 students from a Chinese middle school; half of students formed the experimental group and the rest formed the control group. A 1-year Tai Chi intervention was delivered in 60-minute sessions, five times a week. Both groups were instructed to complete the measure of self-concept at the beginning and end of the intervention. Statistical analysis shows the significant reduction of good behaviour, intellectual and school status, popularity and anxiety in the experimental group compared with the control group. The results suggest that the Tai Chi intervention could improve self-concept in adolescents. © 2014 International Union of Psychological Science.

    Tai chi has been increasingly applied in osteoporosis patients. However, systematic reviews of the efficacy of this practice have been few and of limited scope. This study reviews previous experimental research work using tai chi as an intervention in postmenopausal women with osteoporosis and to appraise the reported research designs used, tai chi methods used, and outcomes. A systematic review method was used to search 14 databases for articles published between January 1980 and July 2013. Searched keywords included: "tai chi," "osteoporosis," and "postmenopausal women". The 2,458 articles initially identified were reduced to 4 valid articles based on considerations of criteria and repeatability. The 4 valid articles used either a randomized clinical trial (RCT) or a controlled clinical trial (CCT). They were further analyzed and synthesized in terms of common variables such as balance, muscle strength, and quality of life. Three of the 4 studies identified significant pretest / posttest differences in physiological aspects of quality of life in participants but did not obtain consistent results in terms of the psychological aspects. While reports identified a significant and positive tai chi effect on balance, they all used different measurements to do so. Only one of the four studies identified significant improvement in muscle strength. Therefore, this review could not identify clear support for the effectiveness of tai chi on balance or muscle strength. This review did not definitively support the positive effects of tai chi on balance, muscle strength, and quality of life in postmenopausal women with osteoporosis. The designs used in the tai chi interventions may be referenced for future studies. We suggest that future studies use data triangulation rather than a single-item tool to validate the research in order to cross-verify the same information. This may strengthen the research and increase the credibility and the validity of related findings.

    The purpose of this study was to examine the mental health effects of Tai chi on regular practitioners by investigating the relationships between flow experience, IKIGAI (Japanese: "Life worth living"), and sense of coherence. The results indicated that flow experience may influence IKIGAI and IKIGAI may influence sense of coherence; this suggests that IKIGAI may act as an intermediary between flow experience and sense of coherence. The results also indicated that the longer the Tai chi experience, the higher was the flow experience.

    Full Text Available Objectives. To evaluate the reporting quality of published randomized clinical trials (RCTs in the Tai Chi literature following the publication of the CONSORT guidelines in 2001. Data Sources. The OVID MEDLINE and PUBMED databases. Review Methods. To survey the general characteristics of Tai Chi RCTs in the literature, we included any report if (i it was an original report of the trial; (ii its design was RCT; (iii one of the treatments being tested was Tai Chi; and (iv it was in English. In addition, we assessed the reporting quality of RCTs that were published between 2002 and 2007, using a modified CONSORT checklist of 40 items. The adequate description of Tai Chi interventions in these trials was examined against a 10-item checklist adapted from previous reviews. Results. The search yielded 31 Tai Chi RCTs published from 2002 to 2007 and only 11 for 1992–2001. Among trials published during 2002–2007, the most adequately reported criteria were related to background, participant eligibility and interpretation of the study results. Nonetheless, the most poorly reported items were associated with randomization allocation concealment, implementation of randomization and the definitions of period of recruitment and follow-up. In addition, only 23% of RCTs provided adequate details of Tai Chi intervention used in the trials. Conclusion. The findings in this review indicated that the reporting quality of Tai Chi intervention trials is sub-optimal. Substantial improvement is required to meet the CONSORT guidelines and allow assessment of the quality of evidence. We believe that not only investigators, but also journal editors, reviewers and funding agencies need to follow the CONSORT guidelines to improve the standards of research and strengthen the evidence base for Tai Chi and for complementary and alternative medicine.

    Cognitive declines are common in older people and can be a major health issue in an aging world. One type of body-mind exercises, t'ai chi, can be a possible means to help maintaining older adults' cognitive abilities, in addition to beneficial effects of physical exercises. The purpose of this study was to investigate whether t'ai chi practitioners had better attention and memory functions than older people with or without regular exercises. A cross-sectional study examining the relationship between t'ai chi practice and age-, gender- and education-similar older peoples' attention and memory functions. Forty-two (42) community-dwelling elderly subjects, aged 60 or older, recruited from t'ai chi clubs in Hong Kong formed the t'ai chi group. Another 49 elderly having regular exercise habits were recruited from community centers for inclusion in the exercise group. A nonexercise group (normal healthy control) consisting of 44 subjects were also recruited by random selection and through contacting local elderly centers. They were also screened by the Modified Barthel Index, Chinese Mini-mental Status Examination, Geriatric Depression Scale, and evaluated by attention tests (Color Trail Form A-1 and 2) and memory tests (including Rivermead Behavioral Memory Test and The Hong Kong List Learning Test). The main finding was that the three groups differed in attention and memory functions, and the t'ai chi group had demonstrated better performance than the other two groups in most subtests. As a causal relationship cannot be assumed in the present cross-sectional study, future research is required to examine how t'ai chi can improve cognitive function using a randomized control trial as well as determining whether t'ai chi practice can lead to better health status among elderly people.

    Full Text Available Objective: To detect the effects of Tai Chi Chuan practice on the cognition of elderly subjects with Mild Cognitive Impairment. Methods: This is a pilot study with 26 elderly patients (mean age of 74 years with Mild Cognitive Impairment. The evaluation instruments were Subjective Memory Complaint Scale (SMC, Rivermead Behavioral Memory Test (RBMT and Digit Span Forward and Backward (DSF and DSB from the Wechsler Adult Intelligence Scale (WAIS. One group of 13 patients received two weekly 60-minute classes of Tai Chi Chuan (Yang style for 6 consecutive months, and the rest formed the Control Group. The Tai Chi Chuan Group was also evaluated as to learning of the Tai Chi Chuan practical exercises by means of a Specific Learning Test applied after three months of intervention. Results: After six months of intervention, the TCC Group showed significant improvement on the RBMT and the SMC (p = 0.007 and p = 0.023, respectively. The Control Group showed no significant differences in the cognitive tests during the study. There was a significant correlation between the Tai Chi Chuan Learning Test and RBMT (p = 0.008, showing that patients with a better performance in exercising TCC also showed a better performance in memory. Conclusions: In this study, a six-month program of Tai Chi Chuan afforded a significant improvement of the performance of memory complaints in the elderly with Mild Cognitive Impairment. Additional randomized studies with larger samples and more prolonged follow-up are needed to confirm these benefits.

    [Purpose] Exercise has been shown to improve cardiovascular fitness and cognitive function. Whether the inclusion of mind over exercise would increase parasympathetic control of the heart and brain activities more than general exercise at a similar intensity is not known. The aim of this study was to compare the effects of Tai Chi (mind-body exercise) versus arm ergometer cycling (body-focused exercise) on the heart rate variability and prefrontal oxygenation level. [Subjects and Methods] A Tai Chi master was invited to perform Tai Chi and arm ergometer cycling with similar exercise intensity on two separate days. Heart rate variability and prefrontal oxyhemoglobin levels were measured continuously by a RR recorder and near-infrared spectroscopy, respectively. [Results] During Tai Chi exercise, spectral analysis of heart rate variability demonstrated a higher high-frequency power as well as a lower low-frequency/high-frequency ratio than during ergometer cycling, suggesting increased parasympathetic and decreased sympathetic control of the heart. Also, prefrontal oxyhemoglobin and total hemoglobin levels were higher than those during arm ergometer exercise. [Conclusion] These findings suggest that increased parasympathetic control of the heart and prefrontal activities may be associated with Tai Chi practice. Having a "mind" component in Tai Chi could be more beneficial for older adults' cardiac health and cognitive function than body-focused ergometer cycling.

    Until recently, studies of fog and cloud chemistry in China have been rare - even though the fate of China’s large sulfur dioxide emissions depends, in part, on the ability of regional clouds to support rapid aqueous oxidation to sulfate. Sulfur dioxide oxidized in regional clouds is more likely to be removed by wet deposition while sulfur dioxide that undergoes slower gas phase oxidation is expected to survive longer in the atmosphere and be transported over a much broader spatial scale. Two 2008 field campaigns conducted at Mt. Tai, an isolated peak on the NE China plain, provide insight into the chemical composition of regional clouds and the importance of various aqueous phase sulfur oxidation pathways. Single and two-stage Caltech Active Strand Cloudwater Collectors were used to collect bulk and drop size-resolved samples of cloudwater. Collected cloudwater was analyzed for key species that influence in-cloud sulfate production, including pH, S(IV), H2O2, Fe and Mn. Other major cloud solutes, including inorganic ions, total organic carbon (TOC), formaldehyde, and organic acids were also analyzed, as were gas phase concentrations of SO2, O3, and H2O2. A wide range of cloud pH was observed, from below 3 to above 6. High concentrations of cloudwater sulfate were consistent with abundant sulfur dioxide emissions in the region. Sampled clouds were also found to contain high concentrations of ammonium, nitrate, and organic carbon. Peak TOC concentrations reached approximately 200 ppmC, among the highest concentrations ever measured in cloudwater. Hydrogen peroxide was found to be the dominant aqueous phase S(IV) oxidant when cloud pH was less than approximately 5.4. Despite its fast reaction with sulfur dioxide in cloud droplets, high concentrations of residual hydrogen peroxide were measured in some clouds implying a substantial additional capacity for sulfate production. Ozone was found to be an important S(IV) oxidant when cloud pH was high. Oxidation of S

    This paper reports a study to examine change in psychosocial status following a 12-week Tai Chi exercise intervention among ethnic Chinese people with cardiovascular disease risk factors living in the United States of America. Regular participation in physical activity is associated with protection against cardioavascular disease, and improvements in physical and psychological health. Increasing amounts of scientific evidence suggests that mind-body exercise, such as Tai Chi, are related to improvements in mental health, emotional well-being, and stress reduction. No prior study has examined the effect of a Tai Chi exercise intervention on psychosocial status among people with cardiovascular disease risk factors. This was a quasi-experimental study. Participants attended a 60-minute Tai Chi exercise class three times per week for 12 weeks. Data were collected at baseline, 6 and 12 weeks following the intervention. Psychosocial status was assessed using Chinese versions of Cohen's Perceived Stress Scale, Profile of Mood States, Multidimensional Scale of Perceived Social Support, and Tai Chi exercise self-efficacy. A total of 39 participants, on average 66-year-old (+/-8.3), married (85%), Cantonese-speaking (97%), immigrants participated. The majority were women (69%), with social support (eta2 = 0.12). Tai Chi was a culturally appropriate mind-body exercise for these older adults, with statistically significant psychosocial benefits observed over 12-weeks. Further research examining Tai Chi exercise using a randomized clinical trial design with an attention-control group may reduce potential confounding effects, while exploring potential mechanisms underlying the relaxation response associated with mind-body exercise. In addition, future studies with people with other chronic illnesses in all ethnic groups are recommended to determine if similar benefits can be achieved.

    Full Text Available Tai Ji Quan is considered to be a part of traditional Chinese Wushu (a martial art and comprises various styles that have evolved historically from the Chen, Yang, Wǔ, Wú, and Sun families (schools. Recent simplification of the original classic styles has made Tai Ji Quan easier to adopt in practice. Thus, the traditional legacy of using Tai Ji Quan for self-defense, mindful nurturing of well-being, and fitness enhancement has been expanded to more contemporary applications that focus on promoting physical and mental health, enhancing general well-being, preventing chronic diseases, and being an effective clinical intervention for diverse medical conditions. As the impact of Tai Ji Quan on physical performance and health continues to grow, there is a need to better understand its historical impact and current status. This paper provides an overview of the evolution of Tai Ji Quan in China, its functional utility, and the scientific evidence of its health benefits, as well as how it has been a vehicle for enhancing cultural understanding and exchanging between East and West.

    The aim of this study is to investigate and compare how 12-weeks of Tai Chi Chuan and Baduanjin exercise can modulate brain structure and memory function in older adults. Magnetic resonance imaging and memory function measurements (Wechsler Memory Scale-Chinese revised, WMS-CR) were applied at both the beginning and end of the study. Results showed that both Tai Chi Chuan and Baduanjin could significantly increase grey matter volume (GMV) in the insula, medial temporal lobe, and putamen after 12-weeks of exercise. No significant differences were observed in GMV between the Tai Chi Chuan and Baduanjin groups. We also found that compared to healthy controls, Tai Chi Chuan and Baduanjin significantly improved visual reproduction subscores on the WMS-CR. Baduanjin also improved mental control, recognition, touch, and comprehension memory subscores of the WMS-CR compared to the control group. Memory quotient and visual reproduction subscores were both associated with GMV increases in the putamen and hippocampus. Our results demonstrate the potential of Tai Chi Chuan and Baduanjin exercise for the prevention of memory deficits in older adults.

    Full Text Available Introduction. Patients with end-stage renal disease (ESRD have poor physical performance and exercise capacity due to frequent dialysis treatments. Tai Chi exercises can be very useful in the area of rehabilitation of people with ESRD. Objectives. The aim of the study was to assess exercise capacity in ESRD patients participating in 6-month Tai Chi training. Patients and Methods. Twenty dialysis patients from Wroclaw took part in the training; at the end of the project, 14 patients remained (age 69.2±8.6 years. A 6-minute walk test (6MWT and spiroergometry were performed at the beginning and after 6 months of training. Results. After 6 months of Tai Chi, significant improvements were recorded in mean distance in the 6MWT (387.89 versus 436.36 m, rate of perceived exertion (7.4 versus 4.7, and spiroergometry (8.71 versus 10.08 min. Conclusions. In the ESRD patients taking part in Tai Chi training, a definite improvement in exercise tolerance was recorded after the 6-month training. Tai Chi exercises conducted on days without dialysis can be an effective and interesting form of rehabilitation for patients, offering them a chance for a better quality of life and fewer falls and hospitalisations that are the result of it.

CCD observations of asteroids were obtained with the 35/51 cm Maksutov-type meniscus telescope and the 1.65 m Ritchey-Chretien reflector. In the Minor Planet Circulars and the Minor Planet Electronic Circulars (2000–2004 we published 6629 astrometric positions of 1114 asteroids. Among them 78 were newly discovered asteroids at Molėtai, a few NEOs were found by our team independently. For the 67 asteroids discovered at Molėtai the precise orbits were calculated. Because of small number of observations, a few asteroids have low-precision orbits and some asteroids have been lost. For seven objects we present their ephemerides for 2015.

    Whether persons with dementia benefit from fall prevention exercise is unclear. Applying the Positive Emotion-Motivated Tai Chi protocol, preliminary findings concerning adherence and effects of a dyadic Tai Chi exercise program on persons with Alzheimer's disease (AD) are reported. Using pre/posttest design, 22 community-dwelling AD-caregiver dyads participated in the program. Fall-risk-relevant functional mobility was measured using Unipedal Stance Time (UST) and Timed Up and Go (TUG) tests. Results showed that 19/22 (86.4%) AD patients completed the 16-week program and final assessment; 16/19 dyads (84.2%) completed the prescribed home program as reported by caregivers. UST adjusted mean improved from 4.0 to 5.1 (Week 4, p .05) post intervention. Retaining dementia patients in an exercise intervention remains challenging. The dyadic Tai Chi approach appears to succeed in keeping AD-caregiver dyads exercising and safe.

  8. A Description and Linguistic Analysis of the Tai Khuen Writing System

    R. Wyn Owen

    2017-03-01

    Full Text Available This article provides a description and linguistic analysis of the Tai Tham script-based orthography of Tai Khuen, a Tai-Kadai language spoken in Eastern Shan State, Myanmar. The language has a long history of writing flowing out of the literary and religious culture nurtured by the Lan Na Kingdom from the 13th Century onwards. Comparison of phoneme and grapheme inventories shows that the orthography is well able to represent the spoken language as well as ancient Pali religious texts. Apart from spelling conventions reflecting the etymology of borrowed Pali and Sanskrit morphemes, sound changes over time have also decreased the phonological transparency of the orthography, notwithstanding the need of some more conservative varieties which still preserve distinctions lost in other varieties. Despite the complexities of the script, the literacy rates in Khuen are remarkably high for a minority language not taught in the government school system.

    Full Text Available Abstract Background Knee Osteoarthritis (KOA is a major cause of pain and functional impairment among elders. Currently, there are neither feasible preventive intervention strategies nor effective medical remedies for the management of KOA. Tai Chi, an ancient Chinese mind-body exercise that is reported to enhance muscle function, balance and flexibility, and to reduce pain, depression and anxiety, may safely and effectively be used to treat KOA. However, current evidence is inconclusive. Our study examines the effects of a 12-week Tai Chi program compared with an attention control (wellness education and stretching on pain, functional capacity, psychosocial variables, joint proprioception and health status in elderly people with KOA. The study will be completed by July 2009. Methods/Design Forty eligible patients, age > 55 yr, BMI ≤ 40 kg/m2 with tibiofemoral osteoarthritis (American College of Rheumatology criteria are identified and randomly allocated to either Tai Chi (10 modified forms from classical Yang style Tai Chi or attention control (wellness education and stretching. The 60-minute intervention sessions take place twice weekly for 12 weeks. The study is conducted at an urban tertiary medical center in Boston, Massachusetts. The primary outcome measure is the Western Ontario and McMaster Universities (WOMAC pain subscale at 12 weeks. Secondary outcomes include weekly WOMAC pain, function and stiffness scores, patient and physician global assessments, lower-extremity function, knee proprioception, depression, self-efficacy, social support, health-related quality of life, adherence and occurrence of adverse events after 12, 24 and 48 weeks. Discussion In this article, we present the challenges of designing a randomized controlled trial with long-term follow up. The challenges encountered in this design are: strategies for recruitment, avoidance of selection bias, the actual practice of Tai Chi, and the maximization of adherence

    Full Text Available Tai people are widely distributed in Thailand, Laos and southwestern China and are a large population of Southeast Asia. Although most anthropologists and historians agree that modern Tai people are from southwestern China and northern Thailand, the place from which they historically migrated remains controversial. Three popular hypotheses have been proposed: northern origin hypothesis, southern origin hypothesis or an indigenous origin. We compared the genetic relationships between the Tai in China and their "siblings" to test different hypotheses by analyzing 10 autosomal microsatellites. The genetic data of 916 samples from 19 populations were analyzed in this survey. The autosomal STR data from 15 of the 19 populations came from our previous study (Lin et al., 2010. 194 samples from four additional populations were genotyped in this study: Han (Yunnan, Dai (Dehong, Dai (Yuxi and Mongolian. The results of genetic distance comparisons, genetic structure analyses and admixture analyses all indicate that populations from northern origin hypothesis have large genetic distances and are clearly differentiated from the Tai. The simulation-based ABC analysis also indicates this. The posterior probability of the northern origin hypothesis is just 0.04 [95%CI: (0.01-0.06]. Conversely, genetic relationships were very close between the Tai and populations from southern origin or an indigenous origin hypothesis. Simulation-based ABC analyses were also used to distinguish the southern origin hypothesis from the indigenous origin hypothesis. The results indicate that the posterior probability of the southern origin hypothesis [0.640, 95%CI: (0.524-0.757] is greater than that of the indigenous origin hypothesis [0.324, 95%CI: (0.211-0.438]. Therefore, we propose that the genetic evidence does not support the hypothesis of northern origin. Our genetic data indicate that the southern origin hypothesis has higher probability than the other two hypotheses

    Full Text Available Abstract Background Post-menopausal osteopenic women are at increased risk for skeletal fractures. Current osteopenia treatment guidelines include exercise, however, optimal exercise regimens for attenuating bone mineral density (BMD loss, or for addressing other fracture-related risk factors (e.g. poor balance, decreased muscle strength are not well-defined. Tai Chi is an increasingly popular weight bearing mind-body exercise that has been reported to positively impact BMD dynamics and improve postural control, however, current evidence is inconclusive. This study will determine the effectiveness of Tai Chi in reducing rates of bone turnover in post-menopausal osteopenic women, compared with standard care, and will preliminarily explore biomechanical processes that might inform how Tai Chi impacts BMD and associated fracture risks. Methods/Design A total of 86 post-menopausal women, aged 45-70y, T-score of the hip and/or spine -1.0 and -2.5, have been recruited from primary care clinics of a large healthcare system based in Boston. They have been randomized to a group-based 9-month Tai Chi program plus standard care or to standard care only. A unique aspect of this trial is its pragmatic design, which allows participants randomized to Tai Chi to choose from a pre-screened list of community-based Tai Chi programs. Interviewers masked to participants' treatment group assess outcomes at baseline and 3 and 9 months after randomization. Primary outcomes are serum markers of bone resorption (C-terminal cross linking telopeptide of type I collagen, bone formation (osteocalcin, and BMD of the lumbar spine and proximal femur (dual-energy X-ray absorptiometry. Secondary outcomes include health-related quality-of-life, exercise behavior, and psychological well-being. In addition, kinetic and kinematic characterization of gait, standing, and rising from a chair are assessed in subset of participants (n = 16 to explore the feasibility of modeling skeletal

    Tai Chi has been widely practiced as a Chinese martial art that focuses on slow sequential movements, providing a smooth, continuous and low intensity activity. It has been promoted to improve balance and strength and to reduce falls in the elderly, especially those 'at risk'. The potential benefits in healthy younger age cohorts and for wider aspects of health have received less attention. The present study documented prospective changes in balance and vascular responses for a community sample of middle-aged women. Seventeen relatively sedentary but healthy normotensive women aged 33-55 years were recruited into a three times per week, 12-week Tai Chi exercise programme. A further 17 sedentary subjects matched for age and body size were recruited as a control group. Dynamic balance measured by the Functional Reach Test was significantly improved following Tai Chi, with significant decreases in both mean systolic (9.71 mmHg) and diastolic (7.53 mmHg) blood pressure. The data confirm that Tai Chi exercise can be a good choice of exercise for middle-aged adults, with potential benefits for ageing as well as the aged.

    Full Text Available Background. This cross-sectional study examined the effect of aging on performing finger-pointing tasks involving choices and whether experienced older Tai Chi practitioners perform better than healthy older controls in such tasks. Methods. Thirty students and 30 healthy older controls were compared with 31 Tai Chi practitioners. All the subjects performed a rapid index finger-pointing task. The visual signal appeared randomly under 3 conditions: (1 to touch a black ball as quickly and as accurately as possible, (2 not to touch a white ball, (3 to touch only the white ball when a black and a white ball appeared simultaneously. Reaction time (RT of anterior deltoid electromyogram, movement time (MT from electromyogram onset to touching of the target, end-point accuracy from the center of the target, and the number of wrong movements were recorded. Results. Young students displayed significantly faster RT and MT, achieving significantly greater end-point accuracy and fewer wrong movements than older controls. Older Tai Chi practitioners had significantly faster MT than older controls. Conclusion. Finger-pointing tasks with a choice paradigm became slower and less accurate with age. Positive findings suggest that Tai Chi may slow down the aging effect on eye-hand coordination tasks involving choices that require more cognitive progressing.

    Tai-Chi has shown benefits in physical and psychological outcomes in diverse populations. We aimed to determine the changes elicited by a Tai-Chi program (12 and 24 weeks) in acute pain (before vs. after session) in fibromyalgia patients. We also assessed the cumulative changes in pain brought about by a Tai-Chi program. Thirty-six patients (29 women) with fibromyalgia participated in a low-moderate intensity Tai-Chi program for 12 weeks (3 sessions/week). Twenty-eight patients (27 women) continued the program for an additional 12 weeks (i. e., 24 weeks). We assessed pain by means of a Visual Analogue Scale (VAS) before and after each single session (i. e., 72 sessions). We observed significant immediate changes (P-values from 0.037 to 0.0001) with an approximately 12% mean decrease of acute pain in the comparison of VAS-values before and after each session (72 sessions in total), with the exception of 4 sessions. We observed significant changes in cumulative pain pre-session (95% CI=-0.019; -0.014; PTai-Chi program for 12 weeks (3 times/week) decreased levels of acute pain in fibromyalgia patients. A longer period is necessary (e. g. 24 weeks) for observing cumulative changes in pain. © Georg Thieme Verlag KG Stuttgart · New York.

    Abstract Objectives To determine the effectiveness of tai chi interventions compared with aerobic exercise, a current core standard treatment in patients with fibromyalgia, and to test whether the effectiveness of tai chi depends on its dosage or duration. Design Prospective, randomized, 52 week, single blind comparative effectiveness trial. Setting Urban tertiary care academic hospital in the United States between March 2012 and September 2016. Participants 226 adults with fibromyalgia (as defined by the American College of Rheumatology 1990 and 2010 criteria) were included in the intention to treat analyses: 151 were assigned to one of four tai chi groups and 75 to an aerobic exercise group. Interventions Participants were randomly assigned to either supervised aerobic exercise (24 weeks, twice weekly) or one of four classic Yang style supervised tai chi interventions (12 or 24 weeks, once or twice weekly). Participants were followed for 52 weeks. Adherence was rigorously encouraged in person and by telephone. Main outcome measures The primary outcome was change in the revised fibromyalgia impact questionnaire (FIQR) scores at 24 weeks compared with baseline. Secondary outcomes included changes of scores in patient’s global assessment, anxiety, depression, self efficacy, coping strategies, physical functional performance, functional limitation, sleep, and health related quality of life. Results FIQR scores improved in all five treatment groups, but the combined tai chi groups improved statistically significantly more than the aerobic exercise group in FIQR scores at 24 weeks (difference between groups=5.5 points, 95% confidence interval 0.6 to 10.4, P=0.03) and several secondary outcomes (patient’s global assessment=0.9 points, 0.3 to 1.4, P=0.005; anxiety=1.2 points, 0.3 to 2.1, P=0.006; self efficacy=1.0 points, 0.5 to 1.6, P=0.0004; and coping strategies, 2.6 points, 0.8 to 4.3, P=0.005).

    This study examined the effects of regular Tai Chi practice and jogging on the neuromuscular activity of the trunk, hip, and ankle joint muscles of older people during lateral postural perturbation. A total of 42 older people participated in the study and formed the Tai Chi, jogging, and sedentary control groups. Electromyography signals were collected from the peroneus longus, anterior tibialis, gluteus medius, and erector spinae during unpredictable mediolateral perturbation. The Tai Chi group exhibited significantly faster latencies of the tibialis anterior and erector spinae than the control group. The jogging group showed a significantly shorter neuromuscular reaction time of the erector spinae than the control group. No significant difference was observed between the Tai Chi and jogging groups. Long-term regular Tai Chi practice enhanced the neuromuscular reaction of the erector spinae and tibialis anterior to lateral perturbation and will help timely posture correction when lateral postural distributions occur.

    Physicians encounter various symptom-based complaints each day. While physicians strive to support patients with chronic illnesses, evidence indicates that patients who are actively involved in their health care have better health outcomes and sometimes lowers costs. This article is to analyze how patient engagement is described when complex interventions such as Tai Chi were delivered in Randomized Controlled clinical Trials (RCTs). It reviews the dynamic patient- physician relationship in chronic illness management and to illustrate the patient engagement process, using Tai Chi as an example intervention. RCTs are considered the gold standard in clinical research. This study is a qualitative analysis of RCTs using Tai Chi as an intervention. A systematic literature search was performed to identify quality randomized controlled clinical trials that investigated the effects of Tai Chi. Selected clinical trials were classified according to research design, intervention style, patient engagement, and outcomes. Patient engagement was classified based on levels of patient participation, compliance, and selfmanagement. The chronic health conditions included in this paper are Parkinson's disease, polyneuropathy, hypertension, stroke, chronic insomnia, chronic heart failure, fibromyalgia, osteoarthritis, central obesity, depression, deconditioning in the elderly, or being pre-clinically disabled. We found that patient engagement, as a concept, was not well defined in literature. It covers a wide range of related terms, such as patient involvement, participation, shared decision- making, patient activation, adherence, compliance, and self-management. Tai Chi, as a very complex practice system, is to balance all aspects of a patient's life; however, the level of patient engagement is difficult to describe using conventional clinical trial design. To accurately illustrate the effect of a complex intervention, novel research design must explore ways to measure patient

    Full Text Available Abstract Background Physical activity and exercise appear to improve psychological health. However, the quantitative effects of Tai Chi on psychological well-being have rarely been examined. We systematically reviewed the effects of Tai Chi on stress, anxiety, depression and mood disturbance in eastern and western populations. Methods Eight English and 3 Chinese databases were searched through March 2009. Randomized controlled trials, non-randomized controlled studies and observational studies reporting at least 1 psychological health outcome were examined. Data were extracted and verified by 2 reviewers. The randomized trials in each subcategory of health outcomes were meta-analyzed using a random-effects model. The quality of each study was assessed. Results Forty studies totaling 3817 subjects were identified. Approximately 29 psychological measurements were assessed. Twenty-one of 33 randomized and nonrandomized trials reported that 1 hour to 1 year of regular Tai Chi significantly increased psychological well-being including reduction of stress (effect size [ES], 0.66; 95% confidence interval [CI], 0.23 to 1.09, anxiety (ES, 0.66; 95% CI, 0.29 to 1.03, and depression (ES, 0.56; 95% CI, 0.31 to 0.80, and enhanced mood (ES, 0.45; 95% CI, 0.20 to 0.69 in community-dwelling healthy participants and in patients with chronic conditions. Seven observational studies with relatively large sample sizes reinforced the beneficial association between Tai Chi practice and psychological health. Conclusions Tai Chi appears to be associated with improvements in psychological well-being including reduced stress, anxiety, depression and mood disturbance, and increased self-esteem. Definitive conclusions were limited due to variation in designs, comparisons, heterogeneous outcomes and inadequate controls. High-quality, well-controlled, longer randomized trials are needed to better inform clinical decisions.

  9. Sensorimotor control of balance: a Tai Chi solution for balance disorders in older subjects.

    In addition to environmental factors, deteriorating sensorimotor control of balance will predispose older adults to falls. Understanding the aging effects on sensorimotor control of balance performance is important for designing fall prevention programs for older adults. How repeated practice of Tai Chi can improve limb joint proprioception, integration of neural signals in the central nervous system for balance control, and motor output at the level of knee muscles is discussed in this chapter. Our previous studies showed that elderly Tai Chi practitioners performed significantly better than elderly nonpractitioners in (1) knee joint proprioception, (2) reduced or conflicting sensory situations that demand more visual or vestibular contributions, (3) standing balance control after vestibular stimulation without visual input, (4) voluntary weight shifting in different directions within the base of support, (5) single-leg stance during perturbations of the support surface, and (6) knee extensor and flexor muscle strength. In a prospective study, we further showed that 4 weeks of daily Tai Chi practice but not general education produced significant improvement in balance performance. The requirements of Tai Chi for accurate joint positioning and weight transfer involving smooth coordination of neck, trunk, upper and lower limb movements, make it particularly useful for improving the sensorimotor control of balance in the elderly. Because Tai Chi can be practiced any time and anywhere, and is well accepted by older people in both the East and now the West, it is especially suited to be a key component of a low-costing community-based fall prevention program alongside with education about environmental factors.

    To determine whether Tai Chi or hydrotherapy classes for individuals with chronic symptomatic hip or knee osteoarthritis (OA) result in measurable clinical benefits. A randomized controlled trial was conducted among 152 older persons with chronic symptomatic hip or knee OA. Participants were randomly allocated for 12 weeks to hydrotherapy classes (n = 55), Tai Chi classes (n = 56), or a waiting list control group (n = 41). Outcomes were assessed 12 and 24 weeks after randomization and included pain and physical function (Western Ontario and McMaster Universities Osteoarthritis Index), general health status (Medical Outcomes Study Short Form 12 Health Survey [SF-12], version 2), psychological well-being, and physical performance (Up and Go test, 50-foot walk time, timed stair climb). At 12 weeks, compared with controls, participants allocated to hydrotherapy classes demonstrated mean improvements (95% confidence interval) of 6.5 (0.4, 12.7) and 10.5 (3.6, 14.5) for pain and physical function scores (range 0-100), respectively, whereas participants allocated to Tai Chi classes demonstrated improvements of 5.2 (-0.8, 11.1) and 9.7 (2.8, 16.7), respectively. Both class allocations achieved significant improvements in the SF-12 physical component summary score, but only allocation to hydrotherapy achieved significant improvements in the physical performance measures. All significant improvements were sustained at 24 weeks. In this almost exclusively white sample, class attendance was higher for hydrotherapy, with 81% attending at least half of the available 24 classes, compared with 61% for Tai Chi. Access to either hydrotherapy or Tai Chi classes can provide large and sustained improvements in physical function for many older, sedentary individuals with chronic hip or knee OA.

    Recent dual-task studies suggest that Tai Chi practitioners displayed better control of standing posture and maintained a quicker response time of postural muscle activation during a stepping down activity. Whether this effect extends to voluntary balance control, specifically the limits of excursion of the center of pressure, remains to be examined. The purpose of this study was to evaluate the cognitive-motor interference pattern by examining the effects of a concurrently performed cognitive task on attention of voluntary balance control in older adults who are long-term practitioners of Tai Chi. Ten older Tai Chi practitioners and 10 age-matched nonpractitioners performed a voluntary balance task that required them to shift their weight to reach a preset target in the forward and backward directions, with (single task, ST) and without (dual task, DT) a secondary cognitive task, which was the counting backward task. The counting backward task required the individual to compute and verbalize a series of arithmetic differences between a given pair of randomly generated numbers. The cognitive task was also performed independently (cognitive-ST). All trials were performed in a random order. Balance outcomes included reaction time, movement velocity, and maximal excursion of the center of pressure provided by the NeuroCom system. Cognitive outcome was the number of correct responses generated within the 8-second trial during the ST and DT conditions. Outcome variables were analyzed using a 2-factor, group by task, analysis of variance. DT costs for the variables were calculated as the relative difference between ST and DT conditions and were compared between the 2 groups using independent t tests. Tai Chi practitioners displayed shorter reaction times (P older nonpractitioners for both directions; however, no difference was found between the maximal excursions of the 2 groups. Cost analyses revealed that reaction time and cognitive costs were significantly lower in

    Preliminary evidence suggests that meditative exercise may have benefits for patients with chronic systolic heart failure (HF); this has not been rigorously tested in a large clinical sample. We sought to investigate whether tai chi, as an adjunct to standard care, improves functional capacity and quality of life in patients with HF. A single-blind, multisite, parallel-group, randomized controlled trial evaluated 100 outpatients with systolic HF (New York Heart Association class I-III, left ventricular ejection fraction ≤40%) who were recruited between May 1, 2005, and September 30, 2008. A group-based 12-week tai chi exercise program (n = 50) or time-matched education (n = 50, control group) was conducted. Outcome measures included exercise capacity (6- minute walk test and peak oxygen uptake) and disease-specific quality of life (Minnesota Living With Heart Failure Questionnaire). Mean (SD) age of patients was 67 (11) years; baseline values were left ventricular ejection fraction, 29% (8%) and peak oxygen uptake, 13.5 mL/kg/min; the median New York Heart Association class of HF was class II. At completion of the study, there were no significant differences in change in 6-minute walk distance and peak oxygen uptake (median change [first quartile, third quartile], 35 [-2, 51] vs 2 [-7, 54] meters, P = .95; and 1.1 [-1.1, 1.5] vs -0.5 [-1.2, 1.8] mL/kg/min, P = .81) when comparing tai chi and control groups; however, patients in the tai chi group had greater improvements in quality of life (Minnesota Living With Heart Failure Questionnaire, -19 [-23, -3] vs 1 [-16, 3], P = .02). Improvements with tai chi were also seen in exercise self-efficacy (Cardiac Exercise Self-efficacy Instrument, 0.1 [0.1, 0.6] vs -0.3 [-0.5, 0.2], P mood (Profile of Mood States total mood disturbance, -6 [-17, 1] vs -1 [-13, 10], P = .01). Tai chi exercise may improve quality of life, mood, and exercise self-efficacy in patients with HF. Trial Registration clinicaltrials.gov Identifier

    Tai'an, a famous cultural tourist district, is a new endemic foci of scrub typhus in northern China. Frequent reports of travel-acquired cases and absence of effective vaccine indicated a significant health problem of scrub typhus in Tai'an. Thus, descriptive epidemiological methods and spatial-temporal scan statistics were used to describe the epidemic characteristics and detect the significant clusters of the high incidence of scrub typhus at the town level in Tai'an. Results of descriptive epidemiological analysis showed a total of 490 cases were reported in Tai'an with the annual average incidence ranging from 0·48 to 2·27/100 000 during 2006-2013. Females, the elderly and farmers are the high-risk groups. Monthly changes of scrub typhus cases indicated an obvious epidemic period in autumn. Spatial-temporal distribution analysis, showed significant clusters of high incidence mainly located in eastern and northern Tai'an. Our study suggests that more effective, targeted measures for local residents should be implemented in the eastern and northern areas of Tai'an in autumn. Meanwhile, it may prove beneficial for health policy makers to advise travellers to take preventive measures in order to minimize the risk of infection of scrub typhus in Tai'an.

    Full Text Available Objective. Patients with schizophrenia residing at institutions often suffer from negative symptoms, motor, and functional impairments more severe than their noninstitutionalized counterparts. Tai-chi emphasizes body relaxation, alertness, and movement coordination with benefits to balance, focus, and stress relief. This pilot study explored the efficacy of Tai-chi on movement coordination, negative symptoms, and functioning disabilities towards schizophrenia. Methods. A randomized waitlist control design was adopted, where participants were randomized to receive either the 6-week Tai-chi program and standard residential care or only the latter. 30 Chinese patients with schizophrenia were recruited from a rehabilitation residency. All were assessed on movement coordination, negative symptoms, and functional disabilities at baseline, following intervention and 6 weeks after intervention. Results. Tai-chi buffered from deteriorations in movement coordination and interpersonal functioning, the latter with sustained effectiveness 6 weeks after the class was ended. Controls showed marked deteriorations in those areas. The Tai-chi group also experienced fewer disruptions to life activities at the 6-week maintenance. There was no significant improvement in negative symptoms after Tai-chi. Conclusions. This study demonstrated encouraging benefits of Tai-chi in preventing deteriorations in movement coordination and interpersonal functioning for residential patients with schizophrenia. The ease of implementation facilitates promotion at institutional psychiatric services.

    Ammonia toxicity varies largely due to its pH- and temperature-dependent speciation (unionized ammonia nitrogen, NH 3 -N). The seasonal and long-term trend of ammonia risk in ecologically significant sections of Tai Lake, China was unknown. In this study, a two-level (deterministic and quantitative) method was developed to assess the special ecological risks posed by NH 3 -N at 37 sites during two seasons (February and September) of 2014 in Tai Lake. The long-term temporal (2004-2015) risk posed by NH 3 -N was also assessed by comparing annual quantitative risk values (probability of exceeding acute or chronic threshold values) in three key sections of Tai Lake. The results indicated the species living in the Tai Lake were at a 0.04% and 32.45% chance of risk due to acute exposure, and a 1.97% and 92.05% chance of risk due to chronic exposure in February and September of 2014, respectively. Alarmingly, the chronic ecological risks of NH 3 -N in the Lanshanzui section of the Tai Lake remained >30% from 2004 to 2011. The chronic risk of NH 3 -N in all three key sections of Tai Lake started to decrease in 2011. This was likely the consequence of the control practice of eutrophication implemented in the Tai Lake. A significant decline in diversity of the benthic invertebrate community of the Tai Lake could be associated with continuous exposure to ammonia over decades given different sensitivity of taxa to ammonia. The results laid a scientific foundation for risk assessment and management of ammonia in Tai Lake, China, and the developed two-level risk assessment approach can also be applied to other similar aquatic regions.

    Antibiotics are widely used in aquaculture and therefore may be present as a dietary risk in cultured aquatic products. Using the Tai Lake Basin as a study area, we assessed the presence of 15 antibiotics in 5 widely cultured aquatic species using a newly developed dietary risk ranking approach. By assigning scores to each factor involved in the ranking matrices, the scores of dietary risks per antibiotic and per aquatic species were calculated. The results indicated that fluoroquinolone antibiotics posed the highest dietary risk in all aquatic species. Then, the total scores per aquatic species were summed by all 15 antibiotic scores of antibiotics, it was found that Crab (Eriocheir sinensis) had the highest dietary risks. Finally, the most concerned antibiotic category and aquatic species were selected. This study highlighted the importance of dietary risk ranking in the production and consumption of cultured aquatic products around Tai Lake. Copyright © 2017 Elsevier Inc. All rights reserved.

    To compare the effectiveness of tai chi and low-level exercise in reducing falls in older adults; to determine whether mobility, balance, and lower limb strength improved and whether higher doses of tai chi resulted in greater effect. Randomized controlled trial. Eleven sites throughout New Zealand. Six hundred eighty-four community-residing older adults (mean age 74.5; 73% female) with at least one falls risk factor. Tai chi once a week (TC1) (n = 233); tai chi twice a week (TC2) (n = 220), or a low-level exercise program control group (LLE) (n = 231) for 20 wks. Number of falls was ascertained according to monthly falls calendars. Mobility (Timed-Up-and-Go Test), balance (step test), and lower limb strength (chair stand test) were assessed. The adjusted incident rate ratio (IRR) for falls was not significantly different between the TC1 and LLE groups (IRR = 1.05, 95% confidence interval (CI) = 0.83-1.33, P = .70) or between the TC2 and LLE groups (IRR = 0.88, 95% CI = 0.68-1.16, P = .37). Adjusted multilevel mixed-effects Poisson regression showed a significant reduction in logarithmic mean fall rate of -0.050 (95% CI = -0.064 to -0.037, P leg) and lower limb strength (P leg), P = .66 (left leg), P = .21, and P = .44, respectively). There was no difference in falls rates between the groups, with falls reducing similarly (mean falls rate reduction of 58%) over the 17-month follow-up period. Strength and balance improved similarly in all groups over time. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

    Tai Lake (Chinese: Taihu), the third-largest freshwater lake in China, suffers from harmful cyanobacteria blooms that are caused by economic development and population growth near the lake. Several studies have focused on phytoplankton in Tai Lake after a drinking water crisis in 2007; however, these studies primarily focused on microcystin bioaccumulation and toxicity to individual species without examining the effects of microcystin on macrobenthic community diversity. In this study, we conducted a survey of the lake to examine the effects of microcystine and other pollutants on marcobenthic community diversity. A totally of forty-nine species of macroinvertebrates were found in Tai Lake. Limnodrilus hoffmeisteri and Corbicula fluminea were the most abundant species. Cluster-analysis and one-way analysis of similarity (ANOSIM) identified three significantly different macrobenthic communities among the sample sites. More specifically, sites in the eastern bays, where aquatic macrophytes were abundant, had the highest diversity of macrobenthic communities, which were dominated by Bellamya aeruginosa, Bellamya purificata, L. hoffmeisteri, and Alocinma longicornis. Sites in Zhushan Bay contained relatively diverse communities, mainly composed of L. hoffmeisteri, C. fluminea, L. claparederanus, R. sinicus, and Cythura sp. Sites in the western region, Meiliang Bay and Wuli Bay had the lowest diversity, mainly composed ofL. hoffmeisteri, C. fluminea, Branchiura sowerbyi, and Rhyacodrilus sinicus. In addition, the relationships between macrobenthic metrics (Shannon–Wiener, Margalef, and Pielou) and environmental variables showed that community structure and spatial patterns of macrobenthos in Tai Lake were significantly influenced by chemical oxygen demand (CODCr), biochemical oxygen demand (BOD5), lead (Pb), and microcystin-LR (L for leucine and R for arginine). Our findings provide critical information that could help managers and policymakers

    The aim of this study was to compare movement kinematics, cocontraction times, and metabolic data in expert and nonexpert Tai Chi practitioners. Significant differences were observed for all kinematic parameters: experts moved smoothly (lower jerk) and with a lower frequency. No differences in metabolic and electromyography data were observed but for the breathing pattern (experts breathed slowly and deeply). Movement frequency and breathing pattern are thus the main features that distinguish expert and nonexpert practitioners.

Material and Methods: A quasi-experimental study with a longitudinal cutting was conducted; the study population was a group of elderly in the city of Popayan. It consisted of three phases: in the first one, an initial evaluation of physical capacity (walking, balance, daily basic activities was applied, afterward, the scale of Yesavage for signs of depression, and finally the Folstien Mini Mental Test to assess cognitive functions. In the second phase, a program of Tai Chi exercises in one weekly session for a twelve weeks period was implemented. In the third phase, the evaluation of the results of the program through participant re-evaluating was carried out. Results: The functional capacity improved in all the tested aspects, the difference in walking speed and the static and dynamic balance were statistically significant; in the same way, the cognitive ability improved in all the tested items, statistical significance was found in aspects such as memory, attention, calculation and language. All participants achieved full functionality of the daily basic activities. Conclusions: The application of a Tai Chi technique provides significant benefits in the balance and the cognitive ability of the elderly, leading to a breakthrough in their independent behavior and improving their functional capacity, so it could be recommended as an alternative technique of physiotherapeutic intervention in neuronal rehabilitation.

    Full Text Available Background: Several studies have shown that Tai Chi Chuan can improve cardiac function in patients with heart disease. Objective: To conduct a systematic review of the literature to assess the effects of Tai Chi Chuan on cardiac rehabilitation for patients with coronary artery disease. Methods: We performed a search for studies published in English, Portuguese and Spanish in the following databases: MEDLINE, EMBASE, LILACS and Cochrane Register of Controlled Trials. Data were extracted in a standardized manner by three independent investigators, who were responsible for assessing the methodological quality of the manuscripts. Results: The initial search found 201 studies that, after review of titles and abstracts, resulted in a selection of 12 manuscripts. They were fully analyzed and of these, nine were excluded. As a final result, three randomized controlled trials remained. The studies analyzed in this systematic review included patients with a confirmed diagnosis of coronary artery disease, all were clinically stable and able to exercise. The three experiments had a control group that practiced structured exercise training or received counseling for exercise. Follow-up ranged from 2 to 12 months. Conclusion: Preliminary evidence suggests that Tai Chi Chuan can be an unconventional form of cardiac rehabilitation, being an adjunctive therapy in the treatment of patients with stable coronary artery disease. However, the methodological quality of the included articles and the small sample sizes clearly indicate that new randomized controlled trials are needed in this regard.

    Full Text Available In order to promote the scientific standardization of Tai-chi-chuan teaching and training, a Tai-chi-chuan auxiliary training system based on Kinect motion capture technology and extraction of the angle feature and speed feature is proposed and designed. The dynamic time planning algorithm (DTW sampling corresponding frame is applied to replace the traditional method of sampling the key frame. The auxiliary training system consists of learning module, action acquisition module and action scoring module. Learning module with stan-dard action teaching video, to meet the requirements of students learning; action acquisition module uses Microsoft developed Kinect equipment to realize data acquisition of the spatial coordinates of the human skeleton in Tai-chi-chuan action, and through filtered noise reduction and the occlusion point data processing the skeleton data is saved. The scoring module constructs the test sequence based on the 16 angle features of eight key joint nodes and the instantaneous velocity characteristics of 20 joint nodes. By comparing with the standard sequence in real time, the original scoring rules is used to achieve the scoring function, which provides students with intuitive and reliable training recommendations, so as to improve the efficiency of learning. By increasing the number of sensors, further designing and optimizing data fusion and filtering algorithm, combining with Microsoft’s Kinect2.0 version, the system can also be applied to medical rehabilitation, physical training analysis and evaluation, virtual reality and human-computer interaction, etc.

    Full Text Available OBJECTIVE: To determine whether Tai Chi Chuan or ballroom dancing promotes better performance with respect to postural balance, gait, and postural transfer among elderly people. METHODS: We evaluated 76 elderly individuals who were divided into two groups: the Tai Chi Chuan Group and the Dance Group. The subjects were tested using the NeuroCom Balance Master¯ force platform system with the following protocols: static balance tests (the Modified Clinical Tests of Sensory Interaction on Balance and Unilateral Stance and dynamic balance tests (the Walk Across Test and Sit-to-stand Transfer Test. RESULTS: In the Modified Clinical Test of Sensory Interaction on Balance, the Tai Chi Chuan Group presented a lower sway velocity on a firm surface with open and closed eyes, as well as on a foam surface with closed eyes. In the Modified Clinical Test of Sensory Interaction on Unilateral Stance, the Tai Chi Chuan Group presented a lower sway velocity with open eyes, whereas the Dance Group presented a lower sway velocity with closed eyes. In the Walk Across Test, the Tai Chi Chuan Group presented faster walking speeds than those of the Dance Group. In the Sit-to-stand Transfer Test, the Tai Chi Chuan Group presented shorter transfer times from the sitting to the standing position, with less sway in the final standing position. CONCLUSION: The elderly individuals who practiced Tai Chi Chuan had better bilateral balance with eyes open on both types of surfaces compared with the Dance Group. The Dance Group had better unilateral postural balance with eyes closed. The Tai Chi Chuan Group had faster walking speeds, shorter transfer times, and better postural balance in the final standing position during the Sit-to-stand Test.

    Aging is a process associated with a decline in cognitive and motor functions, which can be attributed to neurological changes in the brain. Tai Chi, a multimodal mind-body exercise, can be practiced by people across all ages. Previous research identified effects of Tai Chi practice on delaying cognitive and motor degeneration. Benefits in behavioral performance included improved fine and gross motor skills, postural control, muscle strength, and so forth. Neural plasticity remained in the aging brain implies that Tai Chi-associated benefits may not be limited to the behavioral level. Instead, neurological changes in the human brain play a significant role in corresponding to the behavioral improvement. However, previous studies mainly focused on the effects of behavioral performance, leaving neurological changes largely unknown. This systematic review summarized extant studies that used brain imaging techniques and EEG to examine the effects of Tai Chi on older adults. Eleven articles were eligible for the final review. Three neuroimaging techniques including fMRI ( N = 6), EEG ( N = 4), and MRI ( N = 1), were employed for different study interests. Significant changes were reported on subjects' cortical thickness, functional connectivity and homogeneity of the brain, and executive network neural function after Tai Chi intervention. The findings suggested that Tai Chi intervention give rise to beneficial neurological changes in the human brain. Future research should develop valid and convincing study design by applying neuroimaging techniques to detect effects of Tai Chi intervention on the central nervous system of older adults. By integrating neuroimaging techniques into randomized controlled trials involved with Tai Chi intervention, researchers can extend the current research focus from behavioral domain to neurological level.

    To examine whether combined center- and home-based Tai Chi training can improve cognitive ability and reduce physiological fall risk in older adults with amnestic mild cognitive impairment (a-MCI). Randomized controlled trial. Chiang Mai, Thailand. Adults aged 60 and older who met Petersen's criteria for multiple-domain a-MCI (N = 66). Three weeks center-based and 12 weeks home-based Tai Chi (50 minutes per session, 3 times per week). Cognitive tests, including Logical Memory (LM) delayed recall, Block Design, Digit Span forward and backward, and Trail-Making Test Part B-A (TMT B-A), and fall risk index using the Physiological Profile Assessment (PPA). At the end of the trial, performance on LM, Block Design, and TMT B-A were significantly better for the Tai Chi group than the control group after adjusting for baseline test performance. The Tai Chi group also had significantly better composite PPA score and PPA parameter scores: knee extension strength, reaction time, postural sway, and lower limb proprioception. Combined center- and home-based Tai Chi training three times per week for 15 weeks significantly improved cognitive function and moderately reduced physiological fall risk in older adults with multiple-domain a-MCI. Tai Chi may be particularly beneficial to older adults with this condition. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

  2. [About da tai - abortion in old Chinese folk medicine handwritten manuscripts].

    Of 881 Chinese handwritten volumes with medical texts of the 17th through mid-20th century held by Staatsbibliothek zu Berlin and Ethnologisches Museum Berlin-Dahlem, 48 volumes include prescriptions for induced abortion. A comparison shows that these records are significantly different from references to abortion in Chinese printed medical texts of pre-modern times. For example, the percentage of recipes recommended for artificial abortions in handwritten texts is significantly higher than those in printed medical books. Authors of handwritten texts used 25 terms to designate artificial abortion, with the term da tai [see text], lit.: "to strike the fetus", occurring most frequently. Its meaning is well defined, in contrast to other terms used, such as duo tai [see text], lit: "to make a fetus fall", xia tai [see text], lit. "to bring a fetus down", und duan chan [see text], lit., to interrupt birthing", which is mostly used to indicate a temporary or permanent sterilization. Pre-modern Chinese medicine has not generally abstained from inducing abortions; physicians showed a differentiating attitude. While abortions were descibed as "things a [physician with an attitude of] humaneness will not do", in case a pregnancy was seen as too risky for a woman she was offered medication to terminate this pregnancy. The commercial application of abortifacients has been recorded in China since ancient times. A request for such services has continued over time for various reasons, including so-called illegitimate pregnancies, and those by nuns, widows and prostitutes. In general, recipes to induce abortions documented in printed medical literature have mild effects and are to be ingested orally. In comparison, those recommended in handwritten texts are rather toxic. Possibly to minimize the negative side-effects of such medication, practitioners of folk medicine developed mechanical devices to perform "external", i.e., vaginal approaches.

    The purpose of this study was to investigate the benefits of exercises with different cognitive demands for cognitive functions (Executive and non-Executive) in healthy older adults. A cross-sectional design was adopted. In total, 84 healthy older adults were enrolled in the study. They were categorized into the Tai Chi group (TG), the brisk walking group (BG) or the control group (CG). Each participant performed the Stroop task and a digit comparison task. The Stroop task included the following three conditions: a naming condition, an inhibition condition and an executive condition. There were two experimental conditions in the digit comparison task: the non-delay condition and the delay condition. The results indicated that participants of the TG and BG revealed significant better performance than the CG in the executive condition of cognitive tasks and fitness. There was no significant difference of reaction time (RT) and accuracy rate in the inhibition and delay conditions of cognitive tasks and fitness between the TG and BG. The TG showed shorter reaction time in the naming and the executive conditions, and more accurate in the inhibition conditions than the BG. These findings demonstrated that regular participation in brisk walking and Tai Chi have significant beneficial effects on executive function and fitness. However, due to the high cognitive demands of the exercise, Tai Chi benefit cognitive functions (Executive and non-Executive) in older adults more than brisk walking does. Further studies should research the underlying mechanisms at the behavioural and neuroelectric levels, providing more evidence to explain the effect of high-cognitive demands exercise on different processing levels of cognition.

    Background—Tai Chi Chuan (TTC) exercise has beneficial effects on the components of physical condition and can produce a substantial reduction in the risk of multiple falls. Previous studies have shown that short term TCC exercise did not improve the scores in the single leg stance test with eyes closed and the sit and reach test. There has apparently been no research into the effects of TCC on total body rotation flexibility and heart rate responses at rest and after a three minute step test.

    Exercise is effective in reducing falls in people with Parkinson disease. However, information on the cost effectiveness of this approach is lacking. We conducted a cost-effectiveness analysis of Tai Ji Quan for reducing falls among patients with mild-to-moderate Parkinson disease. We used data from a previous intervention trial to analyze resource use costs related to intervention delivery and number of falls observed during a 9-month study period. Cost effectiveness was estimated via incremental cost-effectiveness ratio (ICER) in which Tai Ji Quan was compared with 2 alternative interventions (Resistance training and Stretching) on the primary outcome of per fall prevented and the secondary outcome of per participant quality-adjusted life years (QALY) gained. We also conducted subgroup and sensitivity analyses. Tai Ji Quan was more effective than either Resistance training or Stretching; it had the lowest cost and was the most effective in improving primary and secondary outcomes. Compared with Stretching, Tai Ji Quan cost an average of $175 less for each additional fall prevented and produced a substantial improvement in QALY gained at a lower cost. Results from subgroup and sensitivity analyses showed no variation in cost-effectiveness estimates. However, sensitivity analyses demonstrated a much lower ICER ($27) when only intervention costs were considered. Tai Ji Quan represents a cost-effective strategy for optimizing spending to prevent falls and maximize health gains in people with Parkinson disease. While these results are promising, they warrant further validation.

    To determine if a program of intense Tai Chi exercise that has been shown to reduce the risk of falling in older adults improves postural control by altering the center of pressure (COP) trajectory during gait initiation. Before-after trial. Biomechanics research laboratory. Twenty-eight older adults transitioning to frailty who participated in either a 48-week intervention of intense Tai Chi training or a wellness education (WE) program. Eight Tai Chi forms emphasizing trunk rotation, weight shifting, coordination, and narrowing of lower-extremity stance were taught twice weekly. WE program participants met once a week and received lectures focused on health. Main outcome measures The COP was recorded during gait initiation both before and after the 48-week intervention by using a forceplate sampling at 300 Hz. The COP trajectory was divided into 3 periods (S1, S2, S3) by identifying 2 landmark events. Displacement and average velocity of the COP trace in the anteroposterior (x) and mediolateral (y) directions, as well as smoothness, were calculated. Tai Chi training increased the posterior displacement of the COP during S1 and improved the smoothness of the COP during S2. Tai Chi improved the mechanism by which forward momentum is generated and improved coordination during gait initiation, suggesting improvements in postural control.

    Descending stairs demands attention and neuromuscular control, especially with dual-tasking. Studies have demonstrated that stroke often degrades a survivor's ability to descend stairs. Tai Chi has been shown to improve dual-tasking performance of healthy older adults, but no such study has been conducted in stroke survivors. This study investigated the effect of Tai Chi training on dual-tasking performance that involved stepping down and compared it with that of conventional exercise among stroke survivors. Subjects were randomized into Tai Chi ( n = 9), conventional exercise ( n = 8), and control ( n = 9) groups. Those in the former two groups received 12-week training. Assessments included auditory Stroop test, stepping down test, and dual-tasking test involving both simultaneously. They were evaluated before training (time-1), after training (time-2), and one month after training (time-3). Tai Chi group showed significant improvement in the auditory Stroop test from time-1 to time-3 and the performance was significantly better than that of the conventional exercise group in time-3. No significant effect was found in the stepping down task or dual-tasking in the control group. These results suggest a beneficial effect of Tai Chi training on cognition among stroke survivors without compromising physical task performance in dual-tasking. The effect was better than the conventional exercise group. Nevertheless, further research with a larger sample is warranted.

    This study evaluated whether Tai Ji Quan: Moving for Better Balance (TJQMBB) could improve global cognitive function in older adults with cognitive impairment. Using a nonrandomized control group pretest-posttest design, participants aged ≥65 years who scored between 20 and 25 on the Mini-Mental State Examination (MMSE) were allocated into either a 14-week TJQMBB program (n=22) or a control group (n=24). The primary outcome was MMSE as a measure of global cognitive function with secondary outcomes of 50-ft speed walk, Timed Up&Go, and Activities-Specific Balance Confidence (ABC) scale. At 14 weeks, Tai Ji Quan participants showed significant improvement on MMSE (mean=2.26, pJi Quan participants performed significantly better compared to the controls in both physical performance and balance efficacy measures (p<0.05). Improvement in cognition as measured by MMSE was related to improved physical performance and balance efficacy. These results provide preliminary evidence of the utility of the TJQMBB program to promote cognitive function in older adults in addition to physical benefits. Copyright © 2014 The Authors.

    Developed from traditional Chinese martial arts, Tai Chi exercise includes different forms and interactive Push Hands but biomechanical analyses have focused on the former only. To analyse the techniques of Push Hands, an experienced master was asked to defend pushing by four opponents. Movements were videotaped and digitized using a motion analysis system. Surface electrodes were used to record the electromyographic activity of ten muscle groups. Two force plates were used to measure the ground reaction force on each foot. Inexperienced individuals performed the same procedure to serve as the control group. The results indicate that the master adopted a postural adjustment to maintain balance. A clear shift of body weight from the front to the rear foot and mediolateral displacement of the centre of gravity was observed. Low electromyographic activity was observed in the upper body muscle groups, while high electromyographic activity was observed in the right rectus femoris and very high activity in the left rectus femoris during the defence. All inexperienced participants lost their balance in resisting pushing. It is concluded that the Tai Chi defensive technique includes a subtle postural adjustment that slightly changes the pushing force direction, and allows the rear leg to resist the incoming force.

    In 1893, Wan Tsun-mo translated and published Tai chan ju yao ( Essentials in Obstetrics ), the first monograph of western obstetrics in modern China, symbolizing the independence of obstetrics from such maternal and child books as Fu ying xin shuo and Fu ke jing yun tu shuo , which occupies an important position in the history of the development of modern Chinese obstetrics. The book introduced anatomy, physiology, pathology, embryology, diagnostics, surgery, pharmacology and other knowledge of obstetrics in a catechismal form, and had a detailed discussion of such advanced obstetrical technologies as antiseptic, anesthesia, forceps and cesarean section for the first time.Judging from the content and translation of Tai chan ju yao , this book has already possessed the basic knowledge system of modern obstetrics, though the translation appeared to be somewhat jerky and not elegant and the terminology needing to be further improved, it was not only used as an important medium for the introduction of obstetrical knowledge, but also of great clinical value.However, its influence was so weak that later researchers seldom mentioned this book.

    Total suspended particles (TSP) were collected at the summit of Mt. Tai (1534 m above sea level) on a daytime and nighttime basis during a summertime campaign (May-June 2006) and were characterized for organic molecular compositions using solvent extraction/derivatization and gas chromatography/mass spectrometry technique. The n-Alkanes, fatty acids, fatty alcohols, sugars, glycerol and polyacids, and phthalate esters were found as major organic compound classes, whereas lignin and resin products, sterols, aromatic acids, hopanes, and polycyclic aromatic hydrocarbons (PAHs) were detected as minor classes. Sugars (49.8-2115 ng m-3, average 640 ng m-3 in daytime; 18.1-4348 ng m-3, 799 ng m-3 in nighttime) were found to be the dominant compound class. Levoglucosan, a specific cellulose pyrolysis product, was detected as the most abundant single compound, followed by C28 fatty alcohol, diisobutyl and di-n-butyl phthalates, C29n-alkane, C16 and C28 fatty acids, and malic acid. By grouping organic compounds based on their sources, we found that emission of terrestrial plant waxes was the most significant source (30-34%) of the TSP, followed by biomass burning products (25-27%) (e.g., levoglucosan and lignin and resin products), soil resuspension (15-18%) due to agricultural activities, secondary oxidation products (8-10%), plastic emission (3-10%), marine/microbial sources (6%), and urban/industrial emissions from fossil fuel use (4%). However, low molecular weight dicarboxylic acids (such as oxalic acid) of photochemical origin were not included in this study. Malic acid was found to be much higher than those reported in the ground level, suggesting an enhanced photochemical production in the free troposphere over mountain areas. Temporal variations of biomass burning tracers (e.g., levoglucosan, galactosan, mannosan) and some higher plant wax derived compound classes suggested that there were two major (E1 and E2) and one minor (E3) biomass-burning events during this

    Full Text Available China’s water pollution is severe and has a negative impact on its residents. Establishing an emissions trading mechanism will be helpful for reducing the pollution. However, the government in China controls the emission rights market. The “GDP Only” preference blocks equitable rules to address the externalities. To modify this distortion, we develop a multi-objective primary distribution model that optimizes economic efficiency, environmental contribution, and fairness. In addition, the geographical location of a company and the industry differential are two key factors that would affect the local government’s decision. According to the simulation results using data from Tai Lake in China, this model can effectively help to meet the political expectation that large-scale manufacturers with poor technology can take the initiative to reduce emissions through emission-rights distribution.

    Increasing evidence underscores the health benefits of Tai Chi (TC), although there is limited evidence of benefits among racial and ethnic minorities. This study investigated the impact of psychosocial status on balance among 23 Latino seniors after a twice-a-week, 12-week TC exercise program. Functional status was measured at baseline, immediately after, and three months following the TC exercise program, using the Timed Up and Go Test and Tinetti Falls Efficacy Scale. Psychosocial status was measured at baseline by the Center for Epidemiologic Studies Depression Scale and Norbeck Social Support Questionnaire. Both measures of functional status improved and were sustained after three months of TC. Greater improvement was significantly related to a higher level of baseline social support. More depressed seniors reported less fear of falling after TC. Depression and social support are important moderators of functional improvement after TC among Latino seniors.

    Tai Chi Chuan (TCC) is a Chinese conditioning exercise and is well known for its slow and graceful movements. Recent investigations have found that TCC is beneficial to cardiorespiratory function, strength, balance, flexibility, microcirculation and psychological profile. The long-term practice of TCC can attenuate the age decline in physical function, and consequently it is a suitable exercise for the middle-aged and elderly individuals. TCC can be prescribed as an alternative exercise programme for selected patients with cardiovascular, orthopaedic, or neurological diseases, and can reduce the risk of falls in elderly individuals. The exercise intensity of TCC depends on training style, posture and duration. Participants can choose to perform a complete set of TCC or selected movements according to their needs. In conclusion, TCC has potential benefits in health promotion, and is appropriate for implementation in the community.

    2012-01-01

    Full Text Available As a popular exercise form, Tai Chi (TC has been investigated to determine its contributions to an active and healthy lifestyle. There are an increasing number of researchers who focus on exploring the potential physiological and psychological benefits of TC but only a few systematic reviews of these benefits to a variety of populations. The purpose of this paper is to comprehensively evaluate the reported psychological benefits associated with practicing TC. Although many investigators have reported possible psychological benefits of TC for children, young adults, older healthy adults, and for a variety of patient populations, many of the reports suffer one or more methodological flaws. These flaws include inadequate study design, including lack of control groups, small sample sizes, unsophisticated statistical techniques, or publication without rigorous peer review. After reviewing the results of the existing literature regarding the potential psychological benefits of TC, we recommend that future investigations be conducted with additional adherence to the traditional scientific process.

    Fibromyalgia Syndrome (FMS) is characterized by musculoskeletal pain, muscle tenderness leading to disability, impaired quality of life (QoL), fatigue and it is accompanied by sleep disorders and psychological distress. Mind body therapies (MBT), such as Tai Ji Quan (TJQ), use different techniques to facilitate the ability of the mind to influence disease characteristics and symptoms. Some studies showed that TJQ, in patients with rheumatic diseases, particularly FMS, improved QoL, disability and psychological distress. To evaluate the efficacy of TJQ on disability, QoL, fatigue, sleep and psychological distress in an Italian cohort of FMS patients. We enrolled 44 FMS patients: 22 patients (Experimental Group) participated to a course of Tai Ji Quan style of (2/week for 16 weeks); 22 patients (Control Group) participated to an educational course about FMS (2/week for 16 weeks). At baseline (T0) and at the end of treatment (T1), patients were assessed for disability [Fibromyalgia Impact Questionnaire (FIQ), Health Assessment Questionnaire (HAQ)], Quality of Life [Short-Form 36 (SF36)], fatigue [Functional Assessment of Chronic Illness-Fatigue (FACIT-F)], pain [Widespread Pain Index (WPI)], tenderness [Tender Points (TP)], Sleep Quality [Pittsburgh Sleep Quality Index (PSQI)] and mood disorders [Hospital Anxiety and Depression Scale (HADS)]. At T1 versus T0, patients of the Experimental Group showed a significant improvement in FIQ, FACIT, SF36 (Summary Physical Index, Physical activity, physical role, bodily pain, general health, vitality, emotional role limitations), in WPI, TP, PSQI (total, sleep duration, and sleep disturbance) and HADS (total score and anxiety subscale), while Patients in the Control Group did not improve in any parameter. In FMS patients TJQ, if performed by an expert physiotherapist, should be regarded as an effective rehabilitation method. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Fibromyalgia (FM), one of the most common musculoskeletal disorders, is associated with high levels of impaired health and inadequate or limited symptom relief. The cause of this complex syndrome is unknown, and there is no known cure. Numerous research results indicate that a combination of physical exercise and mind-body therapy is effective in symptom management. T'ai Chi, an ancient Chinese exercise, combines physical exercise with mindbody therapy. To investigate the effects of T'ai Chi exercise on FM symptoms and health-related quality of life. Pilot study, one group pre-to-post posttest design. Participants with FM (n = 39) formed a single group for 6 weeks of 1-hour, twice weekly T'ai Chi exercise classes. FM symptoms and health-related quality of life were measured before and after exercise. Twenty-one participants completed at least 10 of the 12 exercise sessions. Although the dropout rate was higher than expected, measurements on both the Fibromyalgia Impact Questionnaire (FIQ) (Buckhardt, Clark, & Bennett, 1991) and the Short Form-36 (SE-36) (Ware & Sherbourne, 1992) revealed statistically significant improvement in symptom management and health-related quality of life. Knowledge of interventions to enhance health for the patient with musculoskeletal problems is a National Association of Orthopaedic Nurses priority. Tai Chi is potentially beneficial to patients with FM. Further research is needed to support evidence-based practice.

    The Mon-Khmer speaking peoples inhabited northern Thailand before the arrival of the Tai speaking people from southern China in the thirteenth century A.D. Historical and anthropological evidence suggests a close relationship between the Mon-Khmer groups and the present day majority northern Thai groups. In this study, mitochondrial and Y-chromosomal DNA polymorphisms in more than 800 volunteers from eight Mon-Khmer and ten Tai speaking populations were investigated to estimate the degree of genetic divergence between these major linguistic groups and their internal structure. A large fraction of genetic variation is observed within populations (about 80% and 90% for mtDNA and the Y-chromosome, respectively). The genetic divergence between populations is much higher in Mon-Khmer than in Tai speaking groups, especially at the paternally inherited markers. The two major linguistic groups are genetically distinct, but only for a marginal fraction (1 to 2%) of the total genetic variation. Genetic distances between populations correlate with their linguistic differences, whereas the geographic distance does not explain the genetic divergence pattern. The Mon-Khmer speaking populations in northern Thailand exhibited the genetic divergence among each other and also when compared to Tai speaking peoples. The different drift effects and the post-marital residence patterns between the two linguistic groups are the explanation for a small but significant fraction of the genetic variation pattern within and between them. © 2011 Kutanan et al; licensee BioMed Central Ltd.

    Fibromyalgia is a chronic musculoskeletal pain syndrome that causes substantial physical and psychological impairment and costs the US healthcare system over $25 billion annually. Current pharmacological therapies may cause serious adverse effects, are expensive, and fail to effectively improve pain and function. Finding new and effective non-pharmacological treatments for fibromyalgia patients is urgently needed. We are currently conducting the first comparative effectiveness randomized trial of Tai Chi versus aerobic exercise (a recommended component of the current standard of care) in a large fibromyalgia population. This article describes the design and conduct of this trial. A single-center, 52-week, randomized controlled trial of Tai Chi versus aerobic exercise is being conducted at an urban tertiary medical center in Boston, Massachusetts. We plan to recruit 216 patients with fibromyalgia. The study population consists of adults ≥21 years of age with fibromyalgia who meet American College of Rheumatology 1990 and 2010 diagnostic criteria. Participants are randomized to one of four Tai Chi intervention groups: 12 or 24 weeks of supervised Tai Chi held once or twice per week, or a supervised aerobic exercise control held twice per week for 24 weeks. The primary outcome is the change in Revised Fibromyalgia Impact Questionnaire total score from baseline to 24 weeks. Secondary outcomes include measures of widespread pain, symptom severity, functional performance, balance, muscle strength and power, psychological functioning, sleep quality, self-efficacy, durability effects, and health-related quality of life at 12, 24, and 52 week follow-up. This study is the first comparative effectiveness randomized trial of Tai Chi versus aerobic exercise in a large fibromyalgia population with long-term follow up. We present here a robust and well-designed trial to determine the optimal frequency and duration of a supervised Tai Chi intervention with regard to short

    Full Text Available Abstract Background Vestibular rehabilitation (VR is a well-accepted exercise program intended to remedy balance impairment caused by damage to the peripheral vestibular system. Alternative therapies, such as Tai Chi (TC, have recently gained popularity as a treatment for balance impairment. Although VR and TC can benefit people with vestibulopathy, the degree to which gait improvements may be related to neuromuscular adaptations of the lower extremities for the two different therapies are unknown. Methods We examined the relationship between lower extremity neuromuscular function and trunk control in 36 older adults with vestibulopathy, randomized to 10 weeks of either VR or TC exercise. Time-distance measures (gait speed, step length, stance duration and step width, lower extremity sagittal plane mechanical energy expenditures (MEE, and trunk sagittal and frontal plane kinematics (peak and range of linear and angular velocity, were measured. Results Although gait time-distance measures were improved in both groups following treatment, no significant between-groups differences were observed for the MEE and trunk kinematic measures. Significant within groups changes, however, were observed. The TC group significantly increased ankle MEE contribution and decreased hip MEE contribution to total leg MEE, while no significant changes were found within the VR group. The TC group exhibited a positive relationship between change in leg MEE and change in trunk velocity peak and range, while the VR group exhibited a negative relationship. Conclusion Gait function improved in both groups consistent with expectations of the interventions. Differences in each group's response to therapy appear to suggest that improved gait function may be due to different neuromuscular adaptations resulting from the different interventions. The TC group's improvements were associated with reorganized lower extremity neuromuscular patterns, which appear to promote a faster

    Previous researchers have found that 10-form Tai chi yields symptomatic benefit in patients with fibromyalgia (FM). The purpose of this study was to further investigate earlier findings and add a focus on functional mobility. We conducted a parallel-group randomized controlled trial FM-modified 8-form Yang-style Tai chi program compared to an education control. Participants met in small groups twice weekly for 90 min over 12 weeks. The primary endpoint was symptom reduction and improvement in self-report physical function, as measured by the Fibromyalgia Impact Questionnaire (FIQ), from baseline to 12 weeks. Secondary endpoints included pain severity and interference (Brief Pain Inventory (BPI), sleep (Pittsburg sleep Inventory), self-efficacy, and functional mobility. Of the 101 randomly assigned subjects (mean age 54 years, 93 % female), those in the Tai chi condition compared with the education condition demonstrated clinically and statistically significant improvements in FIQ scores (16.5 vs. 3.1, p = 0.0002), BPI pain severity (1.2 vs. 0.4, p = 0.0008), BPI pain interference (2.1 vs. 0.6, p = 0.0000), sleep (2.0 vs. -0.03, p = 0.0003), and self-efficacy for pain control (9.2 vs. -1.5, p = 0.0001). Functional mobility variables including timed get up and go (-.9 vs. -.3, p = 0.0001), static balance (7.5 vs. -0.3, p    0.0001), and dynamic balance (1.6 vs. 0.3, p = 0.0001) were significantly improved with Tai chi compared with education control. No adverse events were noted. Twelve weeks of Tai chi, practice twice weekly, provided worthwhile improvement in common FM symptoms including pain and physical function including mobility. Tai chi appears to be a safe and an acceptable exercise modality that may be useful as adjunctive therapy in the management of FM patients. (ClinicalTrials.gov Identifier, NCT01311427).

    The risk of oxidative stress-related metabolic diseases increases with menopause and physical inactivity. We hypothesized that an 8-week Tai Chi (TC) training program (2 sessions in class; 2 sessions at home; 1-1:15/session) would improve antioxidant capacity and reduce cardiovascular risks in both pre- (n = 8) and postmenopausal (n = 7) sedentary women. Selected measures of physical fitness and blood parameters were analyzed before and after the program. Besides the well-known effects of TC on balance, flexibility, and maximum leg extensor strength, TC (1) increased erythrocyte glutathione peroxidase activity-an aerobic training-responsive antioxidant enzyme-and plasma total antioxidant status and (2) decreased plasma total homocysteine, a cardiovascular risk marker. In addition to being a low-velocity, low-impact, and relatively safe, TC is a suitable physical activity design for pre- and postmenopausal women to increase antioxidant defenses. Investigating breathing effects during TC movements would be an interesting area for further research in diseases prevention.

    To evaluate the effects of coordination exercise on postural stability in older individuals by Chinese shadow boxing, Tai Chi Chuan (TCC). Cross-sectional study. Research project in a hospital-based biomechanical laboratory. The TCC group (n = 25) had been practicing TCC regularly for 2 to 35 years. The control group (n = 14) included healthy and active older subjects. Static postural stability test: progressively harder sequential tests with 6 combinations of vision (eyes open, eyes closed, sway-referenced) and support (fixed, sway-referenced); and dynamic balance test: 3 tests of weight shifting (left to right, forward-backward, multidirectional) at 3 speeds. Static and dynamic balance of Sensory Organization Testing (SOT) of the Smart Balance Master System. In static postural control, the results showed no differences between the TCC or control group in the more simple conditions, but in the more complicated SOT (eyes closed with sway surface, sway vision with sway surface), the TCC group had significantly better results than the control group. The TCC group also had significantly better results in the rhythmic forward-backward weight-shifting test. Duration of practice did not seem to affect the stability of elder people. The elderly people who regularly practiced TCC showed better postural stability in the more challenged conditions than those who do not (eg, the condition with simultaneous disturbance of vision and proprioception). TCC as a coordination exercise may reduce the risk of a fall through maintaining the ability of posture control.

    Full Text Available Jiao Tai Wan (JTW, a Chinese herbal formula containing Rhizoma Coptidis and Cortex Cinnamomi, has been used for diabetic treatment for many years. The aim of this study was to determine the main components in JTW and to investigate the effects of JTW on hepatic lipid accumulation in diabetic rats and humans. JTW extract was prepared and the main components were assayed by HPLC. An animal model of diabetes mellitus was established and JTW was administered intragastrically. In the clinical study, diabetic patients with poor glycemic control were treated with JTW. Blood glucose and lipid parameters, liver histology, hepatic triglyceride content and lipogenic gene expression were examined. Our data demonstrated that JTW significantly improved hyperglycemia, hyperlipidemia and hepatic lipid accumulation in diabetic rats. This was accompanied by the down-regulation of acetyl coenzyme A carboxylase (ACC and fatty acid synthase (FAS protein expressions, and the up-regulation of AMP-activated protein kinase (AMPK and phosphorylated-ACC (pACC protein expressions in the liver tissues. Diabetic patients also exhibited decreases in their hepatic triglyceride content. The results suggest that JTW attenuates hepatic lipid accumulation in diabetic rats and humans. These beneficial effects are possibly associated with the inhibition of lipogenic gene expression in the liver.

    Full Text Available The quantitative and reproducible analysis of the standard body movement in Tai Chi Chuan (TCC was performed in this study. We aimed to provide a reference of the upper extremities for standardizing TCC practice. Microsoft Kinect was used to record the motion during the practice of TCC. The preparation form and eight essential forms of TCC performed by an instructor and 101 practitioners were analyzed in this study. The instructor completed an entire TCC practice cycle and performed the cycle 12 times. An entire cycle of TCC was performed by practitioners and images were recorded for statistics analysis. The performance of the instructor showed high similarity (Pearson correlation coefficient (r=0.71~0.84 to the first practice cycle. Among the 9 forms, lay form had the highest similarity (rmean=0.90 and push form had the lowest similarity (rmean=0.52. For the practitioners, ward off form (rmean=0.51 and roll back form (rmean=0.45 had the highest similarity with moderate correlation. We used Microsoft Kinect to record the spatial coordinates of the upper extremity joints during the practice of TCC and the data to perform quantitative and qualitative analysis of the joint positions and elbow joint angle.

    Full Text Available Whether Tai Chi Chuan (TCC can influence the intrinsic functional architecture of the human brain remains unclear. To examine TCC-associated changes in functional connectomes, resting-state functional magnetic resonance images were acquired from 40 older individuals including 22 experienced TCC practitioners (experts and 18 demographically matched TCC-naïve healthy controls, and their local functional homogeneities across the cortical mantle were compared. Compared to the controls, the TCC experts had significantly greater and more experience-dependent functional homogeneity in the right postcentral gyrus (PosCG and less functional homogeneity in the left anterior cingulate cortex (ACC and the right dorsal lateral prefrontal cortex (DLPFC. Increased functional homogeneity in the PosCG was correlated with TCC experience. Intriguingly, decreases in functional homogeneity (improved functional specialization in the left ACC and increases in functional homogeneity (improved functional integration in the right PosCG both predicted performance gains on attention network behavior tests. These findings provide evidence for the functional plasticity of the brain’s intrinsic architecture toward optimizing locally functional organization, with great implications for understanding the effects of TCC on cognition, behavior and health in aging population.

    Full Text Available Both the incidence and severity of herpes zoster (HZ or shingles increase markedly with increasing age in association with a decline in varicella zoster virus (VZV-specific immunity. Considerable evidence shows that behavioral stressors, prevalent in older adults, correlate with impairments of cellular immunity. Moreover, the presence of depressive symptoms in older adults is associated with declines in VZV-responder cell frequency (VZV-RCF, an immunological marker of shingles risk. In this review, we discuss recent findings that administration of a relaxation response-based intervention, tai chi chih (TCC, results in improvements in health functioning and immunity to VZV in older adults as compared with a control group. TCC is a slow moving meditation consisting of 20 separate standardized movements which can be readily used in elderly and medically compromised individuals. TCC offers standardized training and practice schedules, lending an important advantage over prior relaxation response-based therapies. Focus on older adults at increased risk for HZ and assay of VZV-specific immunity have implications for understanding the impact of behavioral factors and a behavioral intervention on a clinically relevant end-point and on the response of the immune system to infectious pathogens.

    A 12-week Wheelchair Tai Chi 10 Form (WTC10) intervention was conducted among elderly with disability to examine the effect of this WTC10 intervention on selected physical and mental health variables. Thirteen (age 87.23 ± 6.71) in the WTC10 intervention group and 15 (age 89.73 ± 6.31) in the control group completed the study. Independent t-tests and paired t-tests were employed to examine the differences between groups and within groups, respectively, at pretest and post-test. The WTC10 intervention group showed significant improvements in systolic and diastolic blood pressure, shoulder external rotation, left trunk rotation and total trunk rotation after the intervention. A 12-week WTC10 intervention had positive effects on blood pressure, range of motion at the shoulder and trunk, physical activity, and mental health among the elderly with disability. WTC10 is a feasible and safe exercise for the elderly with disability.

    Regular exercise can delay age-related risk factors and can maintain or improve physical health and activity in older adults leading to a decrease in fall risk. The purpose of this study was to compare 2 different interventions for fall prevention, tai chi (TC) and Otago, by examining lower extremity strength, balance, and spatiotemporal gait parameters in community-dwelling older women. We performed a randomized trial in which subjects were assigned to 1 of 2 groups: the TC group (n = 21; age, 72.8 ± 4.7 years, range: 65-83 years), which participated in a modified Sun-style TC exercise program; and the Otago group (n = 24; age, 71.5 ± 3.6 years, range: 65-79 years), which participated in the Otago exercise program. The Timed Up and Go (TUG) test, functional reach (FR) test, one-leg standing (OLS) test, 5 times sit-to-stand test (5×STS), 30-second sit-to-stand (30s STS) test, and gait parameters (gait velocity, step length, step width, stride time, and cadence) were measured before and after the intervention. Both groups showed statistically significant improvements in balance (TUG and OLS tests), lower extremity strength (5×STS and 30s STS tests), and spatiotemporal gait parameters, except for step width and step length (P fall prevention.

    Full Text Available Whilst healthcare professions are already considered one of the most stressful occupations, workplaces are becoming busier, and the potential for workplace absenteeism and burnout has intensified. There is growing evidence that the mind–body practice of Tai Chi, which originated in China as a martial art, has value in treating or preventing many health-related problems, such as stress and anxiety, and that regular practice helps to significantly improve wellbeing, attention, focus, and resilience. This intervention provided 12 sessions of Tai Chi for a group of 12 multidisciplinary healthcare workers and was general wellbeing was measured pre- and post-intervention. Using a mixed methods research design, it was discovered that there were statistically significant gains in well-being during this timeframe with results indicating a strong case for further roll out of the program to a larger pool and more extensive study.

    Background Patients with schizophrenia are characterized by high prevalence rates and chronicity that often leads to long-term institutionalization. Under the traditional medical model, treatment usually emphasizes the management of psychotic symptoms through medication, even though anti-psychotic drugs are associated with severe side effects, which can diminish patients’ physical and psychological well-being. Tai-chi, a mind-body exercise rooted in Eastern health philosophy, emphasizes the m...

  6. Knee osteoarthritis pain in the elderly can be reduced by massage therapy, yoga and tai chi: A review.

    Field, Tiffany

    2016-02-01

    This is a review of recently published research, both empirical studies and meta-analyses, on the effects of complementary therapies including massage therapy, yoga and tai chi on pain associated with knee osteoarthritis in the elderly. The massage therapy protocols have been effective in not only reducing pain but also in increasing range of motion, specifically when moderate pressure massage was used and when both the quadriceps and hamstrings were massaged. The yoga studies typically measured pain by the WOMAC. Most of those studies showed a clinically significant reduction in pain, especially the research that focused on poses (e.g. the Iyengar studies) as opposed to those that had integrated protocols (poses, breathing and meditation exercises). The tai chi studies also assessed pain by self-report on the WOMAC and showed significant reductions in pain. The tai chi studies were difficult to compare because of their highly variable protocols in terms of the frequency and duration of treatment. Larger, randomized control trials are needed on each of these therapies using more standardized protocols and more objective variables in addition to the self-reported WOMAC pain scale, for example, range-of-motion and observed range-of-motion pain. In addition, treatment comparison studies should be conducted so, for example, if the lower-cost yoga and tai chi were as effective as massage therapy, they might be used in combination with or as supplemental to massage therapy. Nonetheless, these therapies are at least reducing pain in knee osteoarthritis and they do not seem to have side effects. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To compare the effect of a custom-designed yoga program with 2 other balance training programs. Randomized controlled trial. Research laboratory. A group of older adults (N=39; mean age, 74.15 ± 6.99 y) with a history of falling. Three different exercise interventions (Tai Chi, standard balance training, yoga) were given for 12 weeks. Balance performance was examined during pre- and posttest using field tests, including the 8-foot up-and-go test, 1-leg stance, functional reach, and usual and maximal walking speed. The static and dynamic balances were also assessed by postural sway and dynamic posturography, respectively. Training produced significant improvements in all field tests (Ptime × group interaction were not detected. For postural sway, significant decreases in the area of the center of pressure with eyes open (P=.001) and eyes closed (P=.002) were detected after training. For eyes open, maximum medial-lateral velocity significantly decreased for the sample (P=.013). For eyes closed, medial-lateral displacement decreased for Tai Chi (Ptime on the test (P=.006), and 2 linear measures in lateral (P=.001) and anterior-posterior (P<.001) directions were seen for the sample. Yoga was as effective as Tai Chi and standard balance training for improving postural stability and may offer an alternative to more traditional programs.

    Health-related quality of life (HRQL) and self-esteem are often diminished among women diagnosed and treated for breast cancer. Tai Chi is a moderate form of exercise that may be an effective therapy for improving HRQL and self-esteem among these women. We sought to compare the efficacy of Tai Chi Chuan (TCC) and psychosocial support (PST) for improving HRQL and self-esteem among breast cancer survivors. A group of 21 women diagnosed with breast cancer, who had completed treatment within the last 30 months were randomized to receive 12 weeks of TCC or PST. Participants in both groups met three times a week for 60 minutes. HRQL and self-esteem were assessed at baseline, 6 weeks, and 12 weeks. The TCC group demonstrated significant improvements in HRQL, while the PST group reported declines in HRQL, with the differences between the two groups approaching significance at week 12. Additionally, the TCC group exhibited improvements in self-esteem, while the PST group reported declines in self-esteem, with the differences between groups reaching statistical significance at week 12. These findings, coupled with a visual inspection of the raw change scores, support the plausibility of a dose-response relationship concerning Tai Chi. In this pilot investigation, the TCC group exhibited improvements in HRQL and self-esteem from baseline to 6 and 12 weeks, while the support group exhibited declines. Randomized, controlled clinical trials with larger sample sizes are needed.

    The purpose of this study was to determine the effectiveness of an 8-week Tai Chi Chih exercise program on physical functional performance (PFP) among women aged 45 to 65 years. A quasi-experimental design with a nonequivalent comparison group was used. Forty-one healthy inactive women were assigned to either an intervention group (n = 19) or a comparison group (n = 19). A 60-min Tai Chi Chih exercise class was conducted twice a week for 8 weeks. PFP was measured at baseline and postintervention using the Continuous Scale Physical Functional Performance-10 (CS-PFP 10). Between-group differences were analyzed using one-way analysis of covariance (ANCOVA). After participating in the 8-week program, intervention group participants showed greater improvement in the CS-PFP measures (p .06). However, the comparison group had little changes. The findings from this study suggest that participation in an 8-week Tai Chi Chih exercise program can improve PFP in healthy, community-dwelling middle-aged women. © The Author(s) 2013.

    2014-04-01

    This study investigates the breathing frequency (BF)-independent effect of Tai Chi Chuan (TCC) on autonomic nervous modulation in TCC practitioners. Twenty-five TCC practitioners and 25 sedentary normal controls were recruited. The stationary heart rate variability (HRV) measures of TCC practitioners and controls were compared. The same HRV measures in TCC practitioners and among the controls, TCC practitioners before TCC and TCC practitioners 30 min after TCC were compared. In TCC practitioners, the BF, normalized high-frequency power (nHFP), and normalized very low-frequency power were significantly increased, while the normalized low-frequency power (nLFP) was significantly decreased 30 min after TCC. The BF correlated significantly and negatively with heart rate (HR), nHFP and nLFP, and correlated significantly and positively with mean RR interval (MnRR) before TCC in TCC practitioners. A slower BF is associated with a higher HR, a greater vagal modulation, and a greater combined sympatho-vagal modulation before TCC. To remove the effect of BF on HRV measures, new indices such as HR*BF, nHFP*BF, nLFP*BF, and MnRR/BF were introduced for comparison among the controls, TCC practitioners before TCC, and TCC practitioners 30 min after TCC. Thirty minutes after TCC, the MnRR/BF of TCC practitioner was smaller whereas HR*BF and nHFP*BF were greater than those before TCC. The BF-independent effects of TCC on the autonomic nervous modulation of TCC practitioners are an increase in vagal modulation and HR, and a decrease in mean RR interval. The mechanism underlying the parallel increase in HR and vagal modulation in TCC practitioners is not understood yet at present.

    Because nutrient enrichment has become increasingly severe in the Tai Lake Basin of China, identifying sources and loads is crucial for watershed nutrient management. This paper develops an empirical framework to estimate nutrient release from five major sectors, which requires fewer input parameters and produces acceptable accuracy. Sectors included are industrial manufacturing, livestock breeding (industrial and family scale), crop agriculture, household consumption (urban and rural), and atmospheric deposition. Results show that in the basin (only the five sectors above), total nutrient loads of nitrogen (N) and phosphorus (P) into aquatic systems in 2008 were 33043.2 tons N a-1 and 5254.4 tons P a-1, and annual area-specific nutrient loads were 1.94 tons N km-2 and 0.31 tons P km-2. Household consumption was the major sector having the greatest impact (46 % in N load, 47 % in P load), whereas atmospheric deposition (18 %) and crop agriculture (15 %) sectors represented other significant proportions of N load. The load estimates also indicate that 32 % of total P came from the livestock breeding sector, making it the second largest phosphorus contributor. According to the nutrient pollution sectors, six best management practices are selected for cost-effectiveness analysis, and feasible options are recommended. Overall, biogas digester construction on industrial-scale farms is proven the most cost-effective, whereas the building of rural decentralized facilities is the best alternative under extreme financial constraint. However, the reduction potential, average monetary cost, and other factors such as risk tolerance of policy makers should all be considered in the actual decision-making process.

    The treatment and disposal of sewage sludge generate considerable amounts of greenhouse gases (GHGs) and pose environmental and economic challenges to wastewater treatment in China. To achieve a more informed and sustainable sludge management, this study conducts a life cycle inventory to investigate the GHG performances of six scenarios involving various sludge treatment technologies and disposal strategies. These scenarios are landfilling (S1), mono-incineration (S2), co-incineration (S3), brick manufacturing (S4), cement manufacturing (S5), and fertilizer for urban greening (S6). In terms of GHG emissions, S2 demonstrates the best performance with its large offset from sludge incineration energy recovery, followed by S4 and S6, whereas S1 demonstrates the poorest performance primarily because of its large quantity of methane leaks. The scenario rankings are affected by the assumptions of GHG offset calculation. In most scenarios, GHG performance could be improved by using waste gas or steam from existing facilities for drying sludge. Furthermore, considering the GHG performance along with economic, health, and other concerns, S6 is recommended. We thus suggest that local governments promote the use of composted sludge as urban greening fertilizers. In addition, the use of sludge with 60% water content, in place of the current standard of 80%, in wastewater treatment plants is proposed to be the new standard for Tai Lake Watershed in China. - Highlights: ► Life-cycle GHG emissions of six sludge handling scenarios are examined. ► Scenario rankings are affected by the assumptions of GHG offset calculation. ► Using heat from existing facilities to dry sludge can improve GHG performance. ► Fertilizer for urban greening is recommended due to its integrated performance. ► The sludge water-content standard is suggested to changed from 80% to 60%.

    Antibiotics are widely used to improve the health and yields of farmed animals, including fish, but their use is accompanied by undesirable ecological effects. Relatively little is known about the water-body burden of antibiotics and their influence on primary productivity in aquaculture ecosystem. In this study, antibiotics usage within 24 fishponds, covering 4 areas, sampled 5 times, and having 5 fish species, was investigated surrounding Tai Lake in China. The study analyzed 15 antibiotics (including 5 sulfonamides, 2 quinolones, 3 β-lactams, 3 tetracyclines, 1 amphenicol, and 1 macrolide), and all of them were detected in water samples, with a detection frequency of 2-60%. Sulfonamides were the most prevalent, and concentrations of sulfamethoxazole, sulfamonomethoxine, and florfenicol being over 2000 ng L(-1) in some samples, while the other antibiotics levels ranged from ND (no detection) to 551.18 ng L(-1). Significant differences were observed in antibiotic burden among different regions for total antibiotics, sulfonamides, quinolones, and amphenicols; among time points for quinolones, β-lactams, and tetracyclines; and among species for quinolones and macrolides. Furthermore, basing on the risk quotient (RQ) method, the assessment revealed that florfenicol was of highest risk to algae with RQ values exceeding 0.1, while macrolide erythromycin posed the second highest risk. The partial correlation coefficient between total antibiotics and chlorophyll (a) was -0.035 that clearly indicated total antibiotics were detrimental to green algae growth, while the nutrient input and other physical - chemical factors were much more beneficial. Overall, holistic far-reaching measures of antibiotics control are recommended to preserve aquaculture ecosystem health. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Tai Chi Chuan (TCC) is known to be a good calisthenics for people. This study examined the relationship between pulse harmonics and autonomic nervous modulation in TCC practitioners. Power spectral measures of right pulse wave and heart rate variability (HRV) measures were compared between TCC practitioners and control subjects. Correlation analyses between pulse harmonics and HRV measures were performed using linear regression analysis. At baseline, the total power of pulse (TPp), powers of all individual pulse harmonics, normalized power of the 1(st) harmonics (nPh1) of TCC practitioners were greater, while the normalized power of the 4(th) pulse harmonics (nPh4) of TCC practitioners was smaller, than those of the controls. Similarly, the baseline standard deviation (SD(RR)), coefficient of variation (CV(RR)), and normalized high-frequency power (nHFP) of RR intervals were smaller, while the normalized very low-frequency power (nVLFP) and low-/high- frequency power ratio (LHR) were larger in the TCC practitioners. The TCC age correlated significantly and negatively with nPh1, and nearly significantly and negatively with nPh2 in the TCC practitioners. Thirty min after TCC exercise, the percentage changes in mRRI, SDRR, TP, VLFP were decreased, while the percentage changes in HR, ULFP, nLFP, and Ph2 were increased, relative to the controls. Correlation analysis shows that the %Ph2 correlates significantly and negatively with %mRRI and significantly and positively with %HR. The TCC practitioners had increased baseline total power of pulse and the 1(st) and 2(nd) pulse harmonics, and decreased power of the 4(th) pulse harmonics, along with decreased vagal modulation and increased sympathetic modulation. After TCC exercise, the power of the 2(nd) harmonics of TCC practitioners was increased which might be related to the increase in HR due to decreased vascular resistance after TCC exercise.

  17. Global Application of TaiWan Ionospheric Model to Single-Frequency GPS Positioning

    Ionospheric delay is one the major sources of error in GPS positioning and navigation. This error in both pseudorange and phase ranges vary depending on the location of observation, local time, season, solar cycle and geomagnetic activity. For single-frequency receivers, this delay is usually removed using ionospheric models. Two of them are the Klobuchar, or broadcast, model and the global ionosphere map (GIM) provided by the International GNSS Service (IGS). In this paper, a three dimensional ionospheric electron (ne) density model derived from FormoSat3/COSMIC GPS Radio Occultation measurements, called the TaiWan Ionosphere Model, is used. It was used to calculate the slant total electron content (STEC) between receiver and GPS satellites to correct the pseudorange single-frequency observations. The corrected pseudorange for every epoch was used to determine a more accurate position of the receiver. Observations were made in July 2, 2011(Kp index = 0-2) in five randomly selected sites across the globe, four of which are IGS stations (station ID: cnmr, coso, irkj and morp) while the other is a low-cost single-frequency receiver located in Chungli City, Taiwan (ID: isls). It was illustrated that TEC maps generated using TWIM exhibited a detailed structure of the ionosphere, whereas Klobuchar and GIM only provided the basic diurnal and geographic features of the ionosphere. Also, it was shown that for single-frequency static point positioning TWIM provides more accurate and more precise positioning than the Klobuchar and GIM models for all stations. The average %error of the corrections made by Klobuchar, GIM and TWIM in DRMS are 3.88%, 0.78% and 17.45%, respectively. While the average %error in VRMS for Klobuchar, GIM and TWIM are 53.55%, 62.09%, 66.02%, respectively. This shows the capability of TWIM to provide a good global 3-dimensional ionospheric model.

    The fate of China’s sulfur dioxide emissions depends, in part, on the ability of regional clouds to support rapid aqueous oxidation of these emissions to sulfate. Sulfur dioxide oxidized in regional clouds is more likely to be removed by wet deposition while sulfur dioxide that undergoes slower gas phase oxidation is expected to survive longer in the atmosphere and exert a radiative forcing impact over a broader spatial scale. Two 2008 field campaigns conducted at Mt. Tai, an isolated peak on the NE China plain, provide insight into the importance of various aqueous phase sulfur oxidation pathways in the region. Single and two-stage cloudwater collectors were used to collect bulk and drop size-resolved samples of cloudwater. Collected cloudwater was analyzed for key species that influence in-cloud sulfate production, including pH, S(IV), H2O2, Fe and Mn. Other major cloud solutes, including inorganic ions, total organic carbon, formaldehyde, and organic acids were also analyzed, as were gas phase concentrations of SO2, O3, and H2O2. A wide range of cloud pH was observed, from below 3 to above 6. High concentrations of cloudwater sulfate were consistent with abundant sulfur dioxide emissions in the region. Despite its fast aqueous reaction with sulfur dioxide, high concentrations of residual hydrogen peroxide were measured in some clouds implying a substantial capacity for additional sulfate production. Ozone was found to be an important S(IV) oxidant in some periods when cloud pH was high. This presentation will examine the importance of different oxidants (H2O2, O3, and O2 catalyzed by trace metals) for sulfur oxidation and the overall capacity of regional clouds to support rapid aqueous phase sulfate production.

    Full Text Available Background: Tai Chi that originated in China as a martial art is an aerobic exercise with low-to-moderate intensity and may play a role in cardiac rehabilitation.Aim: To systematically review the effect of Tai Chi on cardiorespiratory fitness for coronary disease rehabilitation.Methods: We performed a search for Chinese and English studies in the following databases: PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Chinese Biomedical Literature Database, China Knowledge Resource Integrated Database, Wanfang Data, and China Science and Technology Journal Database. The search strategy included terms relating to or describing Tai Chi and coronary disease, and there were no exclusion criteria for other types of diseases or disorders. Further, bibliographies of the related published systematic reviews were also reviewed. The searches, data extraction, and risk of bias (ROB assessments were conducted by two independent investigators. Differences were resolved by consensus. RevMan 5.3.0 was used to analyze the study results. We used quantitative synthesis if the included studies were sufficiently homogeneous and performed subgroup analyses for studies with different control groups. To minimize bias in our findings, we used GRADEpro to grade the available evidence.Results: Five studies were enrolled—two randomized controlled trials (RCTs and three nonrandomized controlled trials (N-RCTs—that included 291 patients. All patients had coronary disease. ROB assessments showed a relatively high selection and detection bias. Meta-analyses showed that compared to other types of low- or moderate-intensity exercise, Tai Chi could significantly improve VO2max [MD = 4.71, 95% CI (3.58, 5.84, P < 0.00001], but it seemed less effective at improving VO2max as compared to high-intensity exercise. This difference, however, was not statistically significant [MD = −1.10, 95% CI (−2.46, 0.26, P = 0.11]. The GRADEpro showed a low level of the

    To investigate the efficacy and safety of Ji-Tai tablet and Ji-Tai tablet combined with buprenorphine in the treatment of patients with acute withdrawal syndrome of mild heroin dependence. A total of 150 patients with mild heroin dependence were recruited, and were randomly assigned to a Ji-Tai tablet group (n=50), a Ji-Tai tablet combined with buprenorphine group (n=50) and a control group (n=50) during a 10-day clinical trial. Opiate withdrawal scale (OWS) was used to measure the severity of withdrawal symptoms. Anxiety symptoms assessments were made at 0 day (baseline), the day 5 (middle), and the day 10 (end) by the Hamilton anxiety scale (HAMA). Symptoms were assessed before and 1 h or 2 h after medication each day. The total withdrawal symptoms scores and the daily reduction rate were used to measure the effect of Ji-Tai tablet vs Ji- Tai tablet plus buprenorphine. Safety evaluation was carried out by the following measures: baseline of treatment, drug side effects after the treatment, vital signs (blood pressure, heart rate, and respiration rate), laboratory examination (routine blood and urine tests and the liver and kidney function tests), and electrocardiograms. A total of 142 mild heroin dependence patients performed the experiments (including 48 in the Ji-Tai tablet group, 48 in the Ji-Tai tablet with buprenorphine group and 46 in the control group). The scores of baseline withdrawal symptoms were 43.520±19.786, 42.640±17.648 and 47.100±24.450, respectively, with no significant differences among the 3 groups (all P>0.05 ). During the 10-day treatment, the reduction rate of acute withdrawal symptoms scores increased daily, the acute withdrawal syndrome scores and the anxiety symptoms scores declined from day 0 to day 10, there was also no significant difference among the 3 groups (all P>0.05). Ji-Tai tablet did not affect vital signs such as blood pressure, heart rate, and respiration rate. Ji-Tai tablet or Ji-Tai tablet combined with buprenorphine

    Background: Falls among the elderly is a major public health concern. Tai Chi exercise appears to prevent the risk of falls among the elderly. Previous reviews found that there is insufficient evidence to conclude whether Tai Chi is effective in fall prevention. Our review was performed to update the current evidence on the effect of this intervention. Methods: We systematically searched Medline, PubMed, Embase, and Cochrane Library for studies published up to 2013. Randomized controlled t...

    There is growing interest in t'ai chi, but little research has addressed whether t'ai chi is effective in older people using wheelchairs for mobilization. The aim of this study was to compare the effects of seated t'ai chi exercise and usual standard activities on mood states and self-efficacy in older people living in a long-term care facility and using wheelchairs for mobilization. Randomized controlled trial (trial registration no. ACTRN12613000029796). One long-term-care facility in Taiwan. Sixty participants were randomly assigned by a computer-generated random sequence to a t'ai chi group (n = 30) or a usual exercise and entertainment activities group (n = 30). Seated t'ai chi exercise for 40 minutes three times a week for 26 weeks was provided. Mood states (Profile of Mood States Short Form [POMS-SF]) and self-efficacy (Self-Efficacy for Exercise [SEE]). At week 26, participants in the t'ai chi group reported significantly lower mood states on the fatigue-inertia dimension of the POMS-SF (mean score ± standard deviation, 3.56 ± 3.71) than did the control group (mean score, 7.16 ± 6.36) (F [1, 58] = 7.15; p self-efficacy for older people using wheelchairs.

    Full Text Available Physical inactivity is one of the major modifiable lifestyle risk factors for cardiovascular disease (CVD. This protocol aims to evaluate the effectiveness of Tai Chi versus brisk walking in reducing CVD risk factors. This is a randomized controlled trial with three arms, namely, Tai Chi group, walking group, and control group. The Tai Chi group will receive Tai Chi training, which consists of two 60-min sessions each week for three months, and self-practice for 30 min every day. The walking group will perform brisk walking for 30 min every day. The control group will receive their usual care. 246 subjects with CVD risk factors will be recruited from two outpatient clinics. The primary outcome is blood pressure. Secondary outcomes include fasting blood for lipid profile, sugar and glycated haemoglobin (HbA1c; body mass index, waist circumference, body fat percentage; perceived stress level and quality of life. Data collections will be conducted at baseline, 3-month, 6-month and 9-month. Generalized estimating equations model will be used to compare the changes in outcomes across time between groups. It is expected that both the Tai Chi and walking groups could maintain better health and have improved quality of life, and that Tai Chi will be more effective than brisk walking in reducing CVD risk factors.

    Full Text Available Objective. The purpose of this systematic review is to evaluate the evidence on the effect of Tai Chi for Parkinson’s disease (PD. Methods. Six electronic databases up to June 2014 were searched. The methodological quality was assessed with PEDro scale. Standardised mean difference and 95% confidence intervals of random-effects model were calculated. Results. Nine studies were included in our review. The aggregated results are in favor of Tai Chi on improving motor function (P=0.002 and balance (P<0.00001 in patients with PD. However, there is no sufficient evidence to support or refute the value of Tai Chi on improving gait velocity (P=0.11, stride length (P=0.21, or quality of life (P=0.40. And there is no valid evidence in follow-up effects of Tai Chi for PD. Conclusion. The current results suggest that Tai Chi can significantly improve the motor function and balance in patients with PD, but there is indeed not enough evidence to conclude that Tai Chi is effective for PD because of the small treatment effect, methodological flaws of eligible studies, and insufficient follow-up. Consequently, high-quality studies with long follow-up are warranted to confirm current beneficial findings.

    Full Text Available Abstract Background Osteoporosis is a major health problem in postmenopausal women. Evidence suggests the importance of oxidative stress in bone metabolism and bone loss. Tea consumption may be beneficial to osteoporosis due to its antioxidant capability. However, lack of objective data characterizing tea consumption has hindered the precise evaluation of the association between tea ingestion and bone mineral density in previous questionnaire-based epidemiological studies. On the other hand, although published studies suggest that Tai Chi (TC exercise can benefit bone health and may reduce oxidative stress, all studies were conducted using a relatively healthy older population, instead of a high-risk one such as osteopenic postmenopausal women. Therefore, this study was designed to test an intervention including green tea polyphenol (GTP and TC exercise for feasibility, and to quantitatively assess their individual and interactive effects on postmenopausal women with osteopenia. Methods/Design One hundred and forty postmenopausal women with osteopenia (defined as bone mineral density T-score at the spine and/or hip between 1 to 2.5 SD below the reference database were randomly assigned to 4 treatment arms: (1 placebo group receiving 500 mg medicinal starch daily, (2 GTP group receiving 500 mg of GTP per day, (3 placebo+TC group receiving both placebo treatment and TC training (60-minute group exercise, 3 times per week, and (4 GTP+TC group receiving both GTP and TC training for 24 weeks. The outcome measures were bone formation biomarker (serum bone alkaline phosphatase, bone resorption biomarker (serum tartrate resistant acid phosphatase, and oxidative DNA damage biomarker (urinary 8-hydroxy-2'-deoxyguanosine. All outcome measures were determined at baseline, 4, 12, and 24 weeks. Urinary and serum GTP concentrations were also determined at baseline, 4, 12, and 24 weeks for bioavailability. Liver function was monitored monthly for safety. A

    Full Text Available Fuzhong Li1,2 1Oregon Research Institute, Eugene, OR, USA; 2Shanghai University of Sport, Shanghai, People’s Republic of ChinaBackground: Limits of stability, defined as the ability to maintain the center of gravity within the boundary of the base of support, is critically important for older adults in performing their activities of daily living. However, few exercise programs specifically tailored to enhance limits of stability exist. The primary purpose of this study was to determine whether a therapeutically designed intervention, Tai Ji Quan: Moving for Better Balance (TJQMBB, could improve limits of stability in older adults. A secondary purpose was to examine concomitant change in limits of stability and physical performance as a result of the intervention.Methods: A single-group design was used in which 145 community-dwelling older adults (average age: 75 years were enrolled in TJQMBB classes, participating twice weekly for 48 weeks. Primary outcome measures were three indicators of limits of stability (LOS (endpoint excursion, movement velocity, and directional control, with secondary measures of physical performance being Timed Up and Go and 50-foot speed walk (in seconds, which were assessed at baseline, 24 weeks, and 48 weeks. Changes in the repeated measures of outcome variables were analyzed via latent curve analysis.Results: At 48 weeks, a significant rate of change (improvement over time was observed in the three limits of stability indicators (endpoint execution: 8.30% LOS, P<0.001; movement velocity: 0.86 degrees/second, P<0.001; directional control: 6.79% of 100, P<0.001; all reached a threshold of real change as judged by the minimal detectable change values. Improvements in the three limits of stability measures were concomitantly correlated with improved (reduced times performance scores in the Timed Up and Go (-0.30, -0.45, and -0.55, ­respectively and 50-foot walk (-0.33, -0.49, and -0.41, respectively

    Full Text Available Tai Chi (TC is a slow-motion contemplative exercise that is associated with improvements in sensorimotor measures, including decreased force variability, enhanced tactile acuity, and improved proprioception, especially in elderly populations. Here, we carried out two studies evaluating the effect of TC practice on measures associated with sensorimotor processing. In study 1, we evaluated TC’s effects on an oscillatory parameter associated with motor function, beta rhythm (15-30 Hz coherence, focusing specifically on beta rhythm intermuscular coherence (IMC, which is tightly coupled to beta corticomuscular coherence (CMC. We utilized electromyography (EMG to compare beta IMC in older TC practitioners with age-matched controls, as well as novices with advanced TC practitioners. Given previous findings of elevated, maladaptive beta coherence in older subjects, we hypothesized that increased TC practice would be associated with a monotonic decrease in beta IMC, but rather discovered that novice practitioners manifested higher beta IMC than both controls and advanced practitioners, forming an inverted U-shaped practice curve. This finding suggests that TC practice elicits complex changes in sensory and motor processes over the developmental lifespan of TC training. In study 2, we focused on somatosensory (e.g., tactile and proprioceptive responses to the Rubber Hand Illusion (RHI in a middle-aged TC group, assessing whether responses to the illusion became dampened with greater cumulative practice. As hypothesized, TC practice was associated with decreased likelihood to misattribute tactile stimulation during the RHI to the rubber hand, although there was no effect of TC practice on measures of proprioception or on subjective reports of ownership. These studies provide preliminary evidence that TC practice modulates beta network coherence in a non-linear fashion, perhaps as a result of the focus on not only efferent motor but also afferent sensory

    The present study examined the effects of a 12-week Tai Chi (TC) training regimen on heart rate variability (HRV), symptomatology, muscle fitness and body composition in women with fibromyalgia. Participants were randomly assigned to either a TC training group (n = 18) or a control group (n = 19). HRV, symptomatology, muscle fitness and body composition were measured before and after 12 weeks. There were significant decreases (p body composition after TC or control. TC may be an effective therapeutic intervention for improving sympathovagal balance, pain, fatigue, strength and flexibility in women with fibromyalgia.

    2015-01-01

    Full Text Available Peripheral neuropathy and loss of somatosensation in older adults with type 2 diabetes can increase risk of falls and disability. In nondiabetic older adult population Tai Chi has been shown to enhance balance and fitness through improvements in somatosensation and neuromuscular control, and it is unclear if Tai Chi would elicit similar benefits in older adults with diabetes. Therefore, the purpose of this study was to investigate the effects of an 8-week, three-hour-per-week Tai Chi intervention on peripheral somatosensation in older adults with type 2 diabetes. Participants were eight Hispanic older adults with type 2 diabetes who participated in the Tai Chi intervention and a convenience sample of Hispanic older adults as a referent group. Baseline and postintervention assessments included ankle proprioception, foot tactile sense, plantar pressure distribution, balance, and fitness. After intervention, older adults with type 2 diabetes showed significant improvements in ankle proprioception and fitness and decreased plantar pressure in the forefoot, with no statistical effect noted in balance or tactile sensation. Study results suggest that Tai Chi may be beneficial for older adults with diabetes as it improves ankle proprioception; however, study findings need to be confirmed in a larger sample size randomized controlled trial.

    Full Text Available Objective. To investigate the effects of sitting Tai Chi on muscle strength, balance control, and quality of life (QOL among survivors with spinal cord injuries (SCI. Methods. Eleven SCI survivors participated in the sitting Tai Chi training (90 minutes/session, 2 times/week for 12 weeks and eight SCI survivors acted as controls. Dynamic sitting balance was evaluated using limits of stability test and a sequential weight shifting test in sitting. Handgrip strength was also tested using a hand-held dynamometer. QOL was measured using the World Health Organization’s Quality of Life Scale. Results. Tai Chi practitioners achieved significant improvements in their reaction time (P=0.042; maximum excursion (P=0.016; and directional control (P=0.025 in the limits of stability test after training. In the sequential weight shifting test, they significantly improved their total time to sequentially hit the 12 targets (P=0.035. Significant improvement in handgrip strength was also found among the Tai Chi practitioners (P=0.049. However, no significant within and between-group differences were found in the QOL outcomes (P>0.05. Conclusions. Twelve weeks of sitting Tai Chi training could improve the dynamic sitting balance and handgrip strength, but not QOL, of the SCI survivors.

    To assess some fall-related clinical variables (balance, gait, fear of falling, functional autonomy, self-actualization and self-efficacy) that might explain the fact that supervised Tai Chi has a better impact on preventing falls compared to a conventional physiotherapy program. The participants (152 older adults over 65 who were admitted to a geriatric day hospital program) were randomly assigned to either a supervised Tai Chi group or the usual physiotherapy. The presence of the clinical variables related to falls was evaluated before the intervention (T1), immediately after (T2), and 12 months after the end of the intervention (T3). Both exercise programs significantly improved fall-related outcomes but only the Tai Chi intervention group decreased the incidence of falls. For both groups, most variables followed the same pattern, i.e. showed significant improvement with the intervention between T1 and T2, and followed by a statistically significant decrease at the T3 evaluation. However, self-efficacy was the only variable that improved solely with the Tai Chi intervention (p = 0.001). The impact of supervised Tai Chi on fall prevention can not be explained by a differential effect on balance, gait and fear of falling. It appeared to be related to an increase of general self-efficacy, a phenomenon which is not seen in the conventional physiotherapy program.

    The study aimed to determine the effects of a 4-month Tai Chi intervention on tenderness, functional capacity, symptomatology, and quality of life in men with fibromyalgia. The effect of a 3-month detraining period was also analyzed. Six men with fibromyalgia (age 52.3 ± 9.3 years) followed a 4-month Tai Chi intervention. The outcome variables were tenderness, functional capacity (30-second chair stand, handgrip strength, chair sit and reach, back scratch, blind flamingo, 8 feet up and go, and 6-minute walk tests), and self-administered questionnaires. A significant improvement (p = .028) after the intervention period for the chair sit and reach test was found, such improvement was maintained after the detraining phase. Tenderness, symptomatology, and quality of life did not significantly change after the intervention period or the detraining phase. In summary, a 4-month Tai Chi intervention improved lower body flexibility in men with fibromyalgia. This improvement persisted after the detraining period.

    Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide. Psychological risk factors such as stress, anxiety and depression are known to play a significant and independent role in the development and progression of CVD and its risk factors. Tai Chi has been reported to be potentially effective for health and well-being. It is of value to assess the effectiveness and safety of Tai Chi on psychological well-being and quality of life in people with CVD and/or cardiovascular risk factors. We will include all relevant randomised controlled trials on Tai Chi for stress, anxiety, depression, psychological well-being and quality of life in people with CVD and cardiovascular risk factors. Literature searching will be conducted until 31 December 2016 from major English and Chinese databases. Two authors will conduct data selection and extraction independently. Quality assessment will be conducted using the risk of bias tool recommended by the Cochrane Collaboration. We will conduct data analysis using Cochrane's RevMan software. Forest plots and summary of findings tables will illustrate the results from a meta-analysis if sufficient studies are identified. Ethics approval is not required as this study will not involve patients. The results of this study will be submitted to a peer-reviewed journal for publication, to inform both clinical practice and further research on Tai Chi and CVDs. This review will summarise the evidence on Tai Chi for psychological well-being and quality of life in people with CVD and their risk factors. We anticipate that the results of this review would be useful for healthcare professionals and researchers on Tai Chi and CVDs.

    To compare the performance of older experienced Tai Chi practitioners and healthy controls in dual-task versus single-task paradigms, namely stepping down with and without performing an auditory response task, a cross-sectional study was conducted in the Center for East-meets-West in Rehabilitation Sciences at The Hong Kong Polytechnic University, Hong Kong. Twenty-eight Tai Chi practitioners (73.6 ± 4.2 years) and 30 healthy control subjects (72.4 ± 6.1 years) were recruited. Participants were asked to step down from a 19-cm-high platform and maintain a single-leg stance for 10 s with and without a concurrent cognitive task. The cognitive task was an auditory Stroop test in which the participants were required to respond to different tones of voices regardless of their word meanings. Postural stability after stepping down under single- and dual-task paradigms, in terms of excursion of the subject's center of pressure (COP) and cognitive performance, was measured for comparison between the two groups. Our findings demonstrated significant between-group differences in more outcome measures during dual-task than single-task performance. Thus, the auditory Stroop test showed that Tai Chi practitioners achieved not only significantly less error rate in single-task, but also significantly faster reaction time in dual-task, when compared with healthy controls similar in age and other relevant demographics. Similarly, the stepping-down task showed that Tai Chi practitioners not only displayed significantly less COP sway area in single-task, but also significantly less COP sway path than healthy controls in dual-task. These results showed that Tai Chi practitioners achieved better postural stability after stepping down as well as better performance in auditory response task than healthy controls. The improved performance that was magnified by dual motor-cognitive task performance may point to the benefits of Tai Chi being a mind-and-body exercise.

    Full Text Available PM2.5 and TSP samples were collected at the summit of Mountain Tai (MT (1534 m a.s.l. in spring 2006/2007 and summer 2006 to investigate the characteristics of aerosols over central eastern China. For comparison, aerosol samples were also collected at Tazhong, Urumqi, and Tianchi in Xinjiang in northwestern China, Duolun and Yulin in northern China, and two urban sites in the megacities, Beijing and Shanghai, in 2007. Daily mass concentrations of TSP and PM2.5 ranged from 39.6–287.6 μg m−3 and 17.2–235.7 μg m−3 respectively at the summit of MT. Averaged concentrations of PM2.5 showed a pronounced seasonal variation with higher concentration in summer than spring. 17 water-soluble ions (SO42−, NO3, Cl, F, PO43−, NO2, CH3COO, CH2C2O42−, C2H4C2O42−, HCOO, MSA, C2O42−, NH4+, Ca2+, K+, Mg2+, Na+, and 19 elements of all samples were measured. SO42−, NO3, and NH4+ were the major water-soluble species in PM2.5, accounting for 61.50 % and 72.65 % of the total measured ions in spring and summer, respectively. The average ratio of PM2.5/TSP was 0.37(2006 and 0.49(2007 in spring, while up to 0.91 in summer, suggesting that aerosol particles were primarily comprised of fine particles in summer and of considerable coarse particles in spring. Crustal elements (e.g., Ca, Mg, Al, Fe, etc. showed higher concentration in spring than summer, while most of the pollution species (SO42−, NO3, K

    Cardiovascular disease is a common health problem resulting from many factors, including dyslipidemia. T'ai chi is one of the interventions assigned to improve lipid profiles and other physical outcomes. However, conflicting results might be attributed to different study designs and interventional approaches. A systematic review and meta-analysis are needed to evaluate existing evidence. The aim of this systematic review and meta-analysis is to evaluate existing randomized clinical trials (RCTs) regarding the overall effect of t'ai chi exercise on lipid profiles. Electronic databases (MEDLINE and Cumulative Index to Nursing and Allied Health Literature) were searched. The authors included only English peer reviewed published RCTs that used a t'ai chi intervention and high-density lipoprotein cholesterol (HDL-C) as the primary outcome along with low-density lipoprotein cholesterol (LDL-C) and/or total cholesterol (TC) as secondary outcomes. The authors identified 37 potentially eligible studies. Only eight RCTs were eligible for their qualitative review, and seven studies were eligible for meta-analysis. The included studies were rated as having a low risk of bias. Despite the overall low risk of bias, all studies failed to blind participants to group assignment and were generally unclear about whether they were selectively reporting data. A fixed effect model (I 2  = 38.16%) demonstrated a small positive effect of t'ai chi on HDL-C (Cohen d = 0.12; standard error [SE] = 0.067; p = 0.037). A random effect model demonstrated a medium effect and small effect for LDL-C (Cohen d = 0.47; SE = 0.347; p = 0.089) and TC (Cohen d = 0.34; SE = 0.225; p = 0.066), respectively. T'ai chi may potentially be beneficial on lipid profiles across different age groups and populations. Although there were conflicting results regarding the effect of t'ai chi on lipid profiles, the majority of studies had at least a small positive effect indicating

    Full Text Available Gaseous and particulate semi-volatile carbonyl compounds were determined every three hours in the atmosphere of Mount Tai (elevation, 1534 m in the North China Plain during 2–5, 23–24 and 25 June 2006 under clear sky conditions. Using a two-step filter cartridge in a series, particulate carbonyls were first collected on a quartz filter and then gaseous carbonyls were collected on a quartz filter impregnated with O-benzylhydroxylamine (BHA. After the two-step derivatization with BHA and N,O-Bis(trimethylsilyltrifluoroacetamide (BSTFA, carbonyl derivatives were measured using a gas chromatography. The gaseous concentrations were obtained as follow: glycolaldehyde (range 0–826 ng m−3, average 303 ng m−3, hydroxyacetone (0–579 ng m−3, 126 ng m−3, glyoxal (46–1200 ng m−3, 487 ng m−3, methylglyoxal (88–2690 ng m−3, 967 ng m−3, n-nonanal (0–500 ng m−3, 89 ng m−3, and n-decanal (0–230 ng m−3, 39 ng m−3. These concentrations are among the highest ever reported in the urban and forest atmosphere. We found that gaseous α-dicarbonyls (glyoxal and methylglyoxal are more than 20 times more abundant than particulate carbonyls and that glycolaldehyde is one order of magnitude more abundant than in aerosol phase. In contrast, hydroxyacetone and normal aldehydes (nonanal and decanal are equally present in both phases. Time-resolved variations of carbonyls did not show any a clear diurnal pattern, except for hydroxyacetone. We found that glyoxal, methylglyoxal and glycolaldehyde positively correlated with levoglucosan (a tracer of biomass burning, suggesting that a contribution from field burning of agricultural wastes (wheat crops is significant for the bifunctional carbonyls in the atmosphere of Mt. Tai. Upward transport of the pollutants to the mountaintop from the low lands in the North China Plain is a major process to control the distributions of carbonyls in the upper atmosphere over Mt. Tai.

    Many studies suggest that Tai Chi exercise is a safe and appropriate mind-body exercise for older people and effectively slows down age-related cognitive decline. A set of bespoke Tai Chi exercise named 'Cognition Protecting Tai Chi' (CPT) has been created for older people with cognitive impairments by the research team of geriatricians, neurologists, rehabilitation specialists, experts of sports medicine and experienced practitioners of traditional Chinese medicine. This trial is designed to evaluate its effects on cognitive function, behaviour/moods, risk of falls and activities of daily living of the participants with mild dementia. A randomised controlled study will be conducted. Eighty participants with mild dementia will be recruited and randomly allocated to an intervention group and a control group. The intervention group will practice the CPT exercise three times a week for 20 min each time under the guidance of professional therapists. The control group will continue receiving their routine treatments. The duration of this study will be 10 months. All participants will be assessed with a battery of neuropsychological and functional evaluations, which include Mini Mental State Examination, Montreal Cognitive Assessment, the WHO-University of California Los Angeles-Auditory Verbal Learning test (WHO-UCLA-AVLT), Trail Making Test (TMT), Geriatric Depression Scale, Neuropsychological Inventory and Barthel Index, at the baseline, 5 and 10 months during the study period. Fall incident will also be recorded. The primary outcome will be the WHO-UCLA-AVLT delayed recall score. The secondary outcome will be the TMT score.

    This study aimed to evaluate a community-based implementation of an evidence-based fall prevention program, in which 131 individuals participated in Tai Chi: Moving for Better Balance. Self-report and functional performance assessments included demographics, health and fall history, the Activities-Specific Balance Scale, the Timed Up and Go test, and the Functional Reach test. Pre-post scores were compared with the Wilcoxon signed rank test. The mostly female participants were 73 years old, on average. At baseline, 18% reported being afraid or very afraid of falling, and 18% had fallen in the past 6 months. At follow-up, there was significant improvement in Timed Up and Go ( p older adults, and can effectively reduce fall risk when implemented in community settings.

    This study explored the immediate effects of Tai Chi (TC) training on attention and meditation, perceived stress level, heart rate, oxygen saturation level in blood, and palmar skin temperature in late middle-aged adults. Twenty TC practitioners and 20 nonpractitioners volunteered to join the study. After baseline measurements were taken, the TC group performed TC for 10 minutes while their cognitive states and cardiovascular responses were concurrently monitored. The control group rested for the same duration in a standing position. Both groups were then reassessed. The participants' attention and meditation levels were measured using electroencephalography; stress levels were measured using Perceived Stress Scale; heart rate and blood oxygenation were measured using an oximeter; and palmar skin temperature was measured using an infrared thermometer. Attention level tended to increase during TC and dropped immediately thereafter ( p training could temporarily improve attention and decrease perceived stress levels, it could not improve meditation, palmar skin temperature, or blood oxygenation among late middle-aged adults.

    Full Text Available The aims of this study were to improve the cost-benefit ratio of the application of artificial insemination in fixed time (TAI by the transcervical route in sheep, to test the dosage reduction and the use of the vulvar submucosa (VSM route as an alternative for the application of equine chorionic gonadotropin (eCG on the efficiency of the synchronization protocol and fertility to artificial insemination (AI and to measure the level of cortisol in ewes as a result the application of this biotechnique. Blood samples were collected before AI, immediately after AI and seven days after AI. Six groups of twenty animals were used, and each group received doses of 200, 300 and 400 IU of eCG by the intramuscular route (IM and VSM. Estrus was detected, and 48 hours later, the inseminations were performed by the transcervical route. Among the 120 treated ewes, 87.5% came in estrus. The percentage of the intrauterine deposition of semen was 88.3%. The pregnancy rate ranged from 20 to 70% between treatments, with an average of 46.66%. The VSM route was viable for the application of eCG in doses of 300 and 400 IU. The reduction in the eCG dose to 200 IU by the IM route reduces costs while maintaining the efficiency of estrus synchronization protocols and TAI with frozen semen in Santa Ines ewes. The average levels of cortisol were significant, at 1.15, 2.86 and 0.52 ?g/dL according to the three collections, being higher after the animal was off the easel at the end of AI. The procedures for performing the transcervical AI technique indicate that stress in the animals produces satisfactory fertility results and a low cost in multiparous ewes of the Santa Ines breed.

    Stress is a major problem in today's fast-paced society and can lead to serious psychosomatic complications. The ancient Chinese mind-body exercise of Tai Chi may provide an alternative and self-sustaining option to pharmaceutical medication for stressed individuals to improve their coping mechanisms. The protocol of this study is designed to evaluate whether Tai Chi practice is equivalent to standard exercise and whether the Tai Chi group is superior to a wait-list control group in improving stress coping levels. This study is a 6-week, three-arm, parallel, randomized, clinical trial designed to evaluate Tai Chi practice against standard exercise and a Tai Chi group against a nonactive control group over a period of 6 weeks with a 6-week follow-up. A total of 72 healthy adult participants (aged 18-60 years) who are either Tai Chi naïve or have not practiced Tai Chi in the past 12 months will be randomized into a Tai Chi group (n = 24), an exercise group (n = 24) or a wait-list group (n = 24). The primary outcome measure will be the State Trait Anxiety Inventory with secondary outcome measures being the Perceived Stress Scale 14, heart rate variability, blood pressure, Short Form 36 and a visual analog scale. The protocol is reported using the appropriate Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) items. Copyright © 2014. Published by Elsevier B.V.

    Contamination by persistent organochlorines (OCs), such as DDTs, hexachlorocyclohexane isomers (HCHs), chlordane compounds (CHLs), hexachlorobenzene (HCB) and polychlorinated biphenyls (PCBs) were examined in sediments, soils, fishes, crustaceans, birds, and aquaculture feed from Lake Tai, Hangzhou Bay, and in the vicinity of Shanghai city in China during 2000 and 2001. OCs were detected in all samples analyzed, and DDT and its metabolites were the predominant contaminants in most sediments, soils and biota. Concentrations of p,p'-DDT and ratio of p,p'-DDT to {sigma}DDTs were significantly higher in marine fishes than those in freshwater fishes. While the use of DDTs has been officially banned in China since 1983, these results indicate a recent input of technical DDTs into the marine environment around Hangzhou Bay. Comparison of organochlorine concentrations in fishes collected from Lake Tai and Hangzhou Bay suggests the presence of local sources of HCHs, chlordanes and PCBs at Lake Tai. Higher proportions of penta- and hexa-PCB congeners in fishes at Lake Tai may suggest the use of highly chlorinated PCB product, such as PCB{sub 5}, around this lake. To our knowledge, this is a first comprehensive study to examine the present status of organochlorine contamination in various environmental media, such as sediments, soils and wildlife, in China. - Elevated concentrations of DDTs were detected in sediments, soils, and wildlife collected from China.

    The effectiveness of pharmacological treatment may be limited in older persons. Several studies using Tai Chi or music therapy separately confirmed positive effects in the reduction of depressive symptoms. We conducted a cluster randomized controlled trial to evaluate the possible synergistic effect of combined music and Tai Chi on depressive symptoms. One hundred and seven older adults with mild to moderate depressive symptoms were recruited from Ya'an city. Fifty-five participants were cluster randomized to combined music and Tai Chi group for three months, while the other fifty-two individuals were randomized to the control group that entailed routine health education delivered monthly by community nurses. The primary outcome of depressive symptoms was measured with the Geriatric Depression Scale (GDS) at baseline and monthly for three months. At three-month follow-up, a statistically significant improvement in depressive symptoms was found in the intervention group compared with control group (F(3,315) = 69.661, P < 0.001). Following adjustments for socio-demographic data, the true effect of intervention on depressive symptoms was significant (F = 41.725, P < 0.01, η p 2 = 0.574). Combined music and Tai Chi reduced depressive symptoms among community-dwelling older persons. This represents an economically viable solution to the management of depression in highly populous developing nations.

Participants: Seventy-five adults (18–40 years from a predominately undergraduate mid-sized university. Methods: This was an assessor blinded, randomized feasibility trial, and participants were randomized into one of three groups: 10 weeks of TCC meeting 2 times per week, 10 weeks of TCC with a DVD of the curriculum, and control group receiving a handout on anxiety management. Anxiety and sleep quality were assessed 4 times: baseline, 4 weeks, 10 weeks (immediate post-intervention, and 2 months post-intervention. Retention was defined as a participant attending the baseline assessment and at least one other assessment. Adherence to the intervention was set a priori as attendance at 80% of the TCC classes. Results: Eighty-five percent of participants were retained during the intervention and 70% completed the 2 month follow-up assessments. To increase statistical power, the two TCC groups were combined in the analyses of anxiety and sleep quality measures. No significant changes in anxiety were found in the control group, while levels of anxiety decreased significantly over time in the two TCC groups. Sleep quality scores improved across time for all three groups, but adherent TCC participants reported greater improvement than control participants. Conclusion: TCC may be an effective nonpharmaceutical means of improving anxiety and poor sleep quality

    The purpose of this study was to explore the effects of a 24-week Tai Ji Quan training program on sleep quality, quality of life, and physical performance among elderly Chinese women with knee osteoarthritis (OA). A 24-week randomized, controlled trial of 46 elderly women with knee OA. Participants were randomly assigned to either a Tai Ji Quan group (n = 23) or a control group (n = 23). Participants in the Tai Ji Quan group completed training sessions three times per week, while those in the control group had bi-weekly educational classes. The primary outcome was total score of the Pittsburgh Sleep Quality of Index (PSQI). Secondary outcomes were: seven subscales of the PSQI; sleep latency; total sleep time; sleep efficiency; physical component summary (PCS) and mental component summary (MCS) of the 36-item Short Form Health Survey (SF-36); Berg Balance Scale (BBS); and Timed Up and Go (TUG). Compared with the control group, participants in the Tai Ji Quan group had significantly improved primary outcome (global PSQI score, p = 0.006) and secondary outcomes, including three PSQI sub-scores (sleep latency, p = 0.031; sleep duration, p = 0.043; daytime dysfunction, p = 0.007), total sleep time (p = 0.033), and SF-36 PCS (p = 0.006). The Tai Ji Quan group also had significant improvements compared with baseline in three PSQI sub-scores (sleep latency, p = 0.031; habitual sleep efficiency, p = 0.049; sleep disturbance, p = 0.016), sleep latency (p = 0.003), BBS (p = 0.001), and TUG (p = 0.006).

    Although pulmonary rehabilitation (PR) is associated with significant clinical benefits in chronic obstructive pulmonary disease (COPD) and has been recommended by guidelines, PR with conventional exercise training has not been widely applied in the clinic because of its inherent limitations. Alternative exercise such as Tai Chi has been investigated and the results are promising. However, the strengths and weaknesses of the exercise modality of Tai Chi, conventional PR and a combination of Tai Chi and conventional PR and the possible mechanisms underlying Tai Chi exercise remain unclear. This study aims to address the above research gaps in a well-designed clinical trial. This study is a single-blind, randomised controlled trial. Participants with stable COPD will be recruited and randomly assigned to one of four groups receiving Tai Chi exercise, conventional PR using a total body recumbent stepper (TBRS), combined Tai Chi and TBRS, or usual care (control) in a 1:1:1:1 ratio. Participants will perform 30 min of supervised exercise three times a week for 8 weeks; they will receive sequential follow-ups until 12 months after recruitment. The primary outcome will be health-related quality of life as measured by the St George's Respiratory Questionnaire. Secondary outcomes will include 6 min walking distance, pulmonary function, the modified Medical Research Council Dyspnoea Scale, the COPD Assessment Test, the Hospital Anxiety and Depression Scale, the Berg Balance Scale, exacerbation frequency during the study period, and systemic inflammatory and immune markers. Ethics approval has been granted by the Clinical Trial and Biomedical Ethics Committee of West China Hospital of Sichuan University (No TCM-2015-82). Written informed consent will be obtained from each participant before any procedures are performed. The study findings will be published in peer-reviewed journals and presented at national and international conferences. ChiCTR-IOR-15006874; Pre

    Full Text Available Abstract Background Falls are a significant public health problem. Thirty to fifty percent of the elderly of 65 years and older fall each year. Falls are the most common type of accident in this age group and can result in fractures and subsequent disabilities, increased fear of falling, social isolation, decreased mobility, and even an increased mortality. Several forms of exercise have been associated with a reduced risk of falling and with a wide range of physiological as well as psychosocial health benefits. Tai Chi Chuan seems to be the most promising form of exercise in the elderly, but the evidence is still controversial. In this article the design of a randomized clinical trial is presented. The trial evaluates the effect of Tai Chi Chuan on fall prevention and physical and psychological function in older adults. Methods/Design 270 people of seventy years and older living at home will be identified in the files of the participating general practitioners. People will be asked to participate when meeting the following inclusion criteria: have experienced a fall in the preceding year or suffer from two of the following risk factors: disturbed balance, mobility problems, dizziness, or the use of benzodiazepines or diuretics. People will be randomly allocated to either the Tai Chi Chuan group (13 weeks, twice a week or the no treatment control group. The primary outcome measure is the number of new falls, measured with a diary. The secondary outcome measures are balance, fear of falling, blood pressure, heart rate, lung function parameters, physical activity, functional status, quality of life, mental health, use of walking devices, medication, use of health care services, adjustments to the house, severity of fall incidents and subsequent injuries. Process parameters will be measured to evaluate the Tai Chi Chuan intervention. A cost-effectiveness analysis will be carried out alongside the evaluation of the clinical results. Follow

    To examine the effects of Tai Chi and walking training on aerobic fitness, resting energy expenditure (REE), body composition, and quality of life; as well as analyzing the energy metabolism during exercises, to determine which one had better advantage in improving health status. Three hundred seventy-four middle-aged Chinese subjects who were recruited from nine geographic areas in Sha Tin were randomized into Tai Chi, walking, or control groups at area level. The 12-week (45min per day, 5days per week) Tai Chi or brisk walking training were conducted in respective intervention groups. Measures were performed at baseline and end of trial. Another 30 subjects were recruited to compare the energy metabolism between practicing Tai Chi and walking. The between-group difference of VO2max was 3.3ml/min/kg for Tai Chi vs. control and 3.7ml/min/kg for walking vs. control (both Pwalking. Regarding to energy metabolism test, the self-paced walking produced approximately 46% higher metabolic costs than Tai Chi. Practicing Tai Chi consumes a smaller amount of energy metabolism but similar health benefits as self-paced brisk walking. Copyright © 2016. Published by Elsevier Ltd.

  15. Can Tai Chi and Qigong Postures Shape Our Mood? Toward an Embodied Cognition Framework for Mind-Body Research

    Kamila Osypiuk

    2018-05-01

    Full Text Available Dynamic and static body postures are a defining characteristic of mind-body practices such as Tai Chi and Qigong (TCQ. A growing body of evidence supports the hypothesis that TCQ may be beneficial for psychological health, including management and prevention of depression and anxiety. Although a variety of causal factors have been identified as potential mediators of such health benefits, physical posture, despite its visible prominence, has been largely overlooked. We hypothesize that body posture while standing and/or moving may be a key therapeutic element mediating the influence of TCQ on psychological health. In the present paper, we summarize existing experimental and observational evidence that suggests a bi-directional relationship between body posture and mental states. Drawing from embodied cognitive science, we provide a theoretical framework for further investigation into this interrelationship. We discuss the challenges involved in such an investigation and propose suggestions for future studies. Despite theoretical and practical challenges, we propose that the role of posture in mind-body exercises such as TCQ should be considered in future research.

    To compare the effect of two 10-week balance training programs, Combined Balance and Step Training (CBST) versus tai chi (TC), on balance and stepping measures. Prospective intervention trial. Local senior centers and congregate housing facilities. Aged 65 and older with at least mild impairment in the ability to perform unipedal stance and tandem walk. Participants were allocated to TC (n = 107, mean age 78) or CBST, an intervention focused on improving dynamic balance and stepping (n = 106, mean age 78). At baseline and 10 weeks, participants were tested in their static balance (Unipedal Stance and Tandem Stance (TS)), stepping (Maximum Step Length, Rapid Step Test), and Timed Up and Go (TUG). Performance improved more with CBST than TC, ranging from 5% to 10% for the stepping tests (Maximum Step Length and Rapid Step Test) and 9% for TUG. The improvement in TUG represented an improvement of more than 1 second. Greater improvements were also seen in static balance ability (in TS) with CBST than TC. Of the two training programs, in which variants of each program have been proven to reduce falls, CBST results in modest improvements in balance, stepping, and functional mobility versus TC over a 10-week period. Future research should include a prospective comparison of fall rates in response to these two balance training programs.

    2015-01-01

    The aim of this study was to compare experts to naïve practitioners in rating the beauty and the technical quality of a Tai Chi sequence observed in video-clips (of high and middle level performances). Our hypothesis are: i) movement evaluation will correlate with the level of skill expressed in the kinematics of the observed action but ii) only experts will be able to unravel the technical component from the aesthetic component of the observed action. The judgments delivered indicate that both expert and non-expert observers are able to discern a good from a mediocre performance; however, as expected, only experts discriminate the technical from the aesthetic component of the action evaluated and do this independently of the level of skill shown by the model (high or middle level performances). Furthermore, the judgments delivered were strongly related to the kinematic variables measured in the observed model, indicating that observers rely on specific movement kinematics (e.g. movement amplitude, jerk and duration) for action evaluation. These results provide evidence of the complementary functional role of visual and motor action representation in movement evaluation and underline the role of expertise in judging the aesthetic quality of movements.

    Full Text Available Tai Chi and walking are both moderate-intensity physical activity (PA that can be easily practiced in daily life. The objective of the study was to determine the effects of these two PAs on weight loss, metabolic syndrome parameters, and bone mineral density (BMD in Chinese adults. We randomized 374 middle-aged subjects (45.8 ± 5.3 years into 12-week training (45 minutes per day, 5 days per week of Tai Chi (n=124 or self-paced walking (n=121 or control group (n=129. On average, Tai Chi and walking groups lost 0.50 and 0.76 kg of body weight and 0.47 and 0.59 kg of fat mass after intervention, respectively. The between-group difference of waist circumference (WC and fasting blood glucose (FBG was −3.7 cm and −0.18 mmol/L for Tai Chi versus control and −4.1 cm and −0.22 mmol/L for walking versus control. No significant differences were observed regarding lean mass, blood pressure, triglycerides, total cholesterol, high-density and low-density lipoprotein cholesterol, and BMD compared to control. Change in lean mass, not fat mass or total weight loss, was significantly correlated to the change in BMD. Our results suggest that both of these two PAs can produce moderate weight loss and significantly improve the WC and FBG in Hong Kong Chinese adults, with no additional effects on BMD.

This study aimed to test the efficacy of the “Tai Chi for Diabetes” form, developed to address health-related problems in diabetes, including mobility and physical function. Thirty-eight older adults with stable type 2 diabetes were randomized to Tai Chi or sham exercise, twice a week for 16 weeks. Outcomes included gait, balance, musculoskeletal and cardiovascular fitness, self-reported activity and quality of life. Static and dynamic balance index (−5.8 ± 14.2; p = 0.03 and maximal gait speed (6.2 ± 11.6%; p = 0.005 improved over time, with no significant group effects. There were no changes in other measures. Non-specific effects of exercise testing and/or study participation such as outcome expectation, socialization, the Hawthorne effect, or unmeasured changes in health status or compliance with medical treatment may underlie the modest improvements in gait and balance observed in this sham-exercise-controlled trial. This Tai Chi form, although developed specifically for diabetes, may not have been of sufficient intensity, frequency, or duration to effect positive changes in many aspects of physiology or health status relevant to older people with diabetes.Keywords: Tai Chi, Type 2 diabetes, physical function

    Objectives. The advantageous effect of physical exercise on bones has been proven. Quantitative ultrasound (QUS) at different skeletal sites is an accepted method for indirect and noninvasive assessment of bone quality and fracture risk. Earlier, the present authors showed higher values of ultrasound transmission in the hand phalanges of a group of Polish women practicing Tai Chi. The aim of the present study was a prospective assessment of skeletal status in women practicing Tai Chi. Material and Methods. One-year follow-up of skeletal status was assessed using QUS measurements at the hand phalanges in a group of 46 exercising women (mean age: 59.3 ± 8.7 years). Results. At follow-up, increases in the mean amplitude-dependent speed of sound (Ad-SoS) from 1995 ± 80 to 2012 ± 75 m/s (p = 0.001) and mean Z-score from 0.673 ± 1.054 to 1.053 ± 1.178 (p = 0.0005) were observed in the exercising subjects. These changes revealed statistically significant positive correlation with subject age (r = 0.39, p = 0.007 and r = 0.35, p 0.018, respectively). The increase in Ad-SoS exceeded the value of the '' least significant change '' in 19 subjects (41%) of the total group and in 2 (22%) incorporated into medithe pre- and postmenopausal subgroups, respectively. Conclusions. A beneficial effect of regular Tai Chi exercise on skeletal status as assessed by phalangeal QUS is observed in older women. Tai Chi gymnastics may be recommended in the prevention of postmenopausal osteoporosis, especially in older individuals. (authors)

    Aging is typically associated with progressive multi-system impairment that leads to decreased physical and cognitive function and reduced adaptability to stress. Due to its capacity to characterize complex dynamics within and between physiological systems, the emerging field of complex systems biology and its array of quantitative tools show great promise for improving our understanding of aging, monitoring senescence, and providing biomarkers for evaluating novel interventions, including promising mind-body exercises, that treat age-related disease and promote healthy aging. An ongoing, two-arm randomized clinical trial is evaluating the potential of Tai Chi mind-body exercise to attenuate age-related loss of complexity. A total of 60 Tai Chi-naïve healthy older adults (aged 50-79) are being randomized to either six months of Tai Chi training (n=30), or to a waitlist control receiving unaltered usual medical care (n=30). Our primary outcomes are complexity-based measures of heart rate, standing postural sway and gait stride interval dynamics assessed at 3 and 6months. Multiscale entropy and detrended fluctuation analysis are used as entropy- and fractal-based measures of complexity, respectively. Secondary outcomes include measures of physical and psychological function and tests of physiological adaptability also assessed at 3 and 6months. Results of this study may lead to novel biomarkers that help us monitor and understand the physiological processes of aging and explore the potential benefits of Tai Chi and related mind-body exercises for healthy aging.

    Objective was to investigate the effects of Tai Chi exercise on nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S) levels, and blood pressure (BP) in patients with essential hypertension (EH). EH patients were assigned to the Tai Chi exercise group (HTC, n = 24), and hypertension group (HP, n = 16) by patients' willingness. Healthy volunteers matched for age and gender were recruited as control (NP, n = 16). HTC group performed Tai Chi (60 min/d, 6 d/week) for 12 weeks. Measurements (blood glucose, cholesterol, NO, CO, H2S and BP) were obtained at week 0, 6, and 12. SBP, MAP, and low-density lipoprotein cholesterol levels decreased, and high-density lipoprotein cholesterol levels increased by week 12 in the HTC group (all p exercise seems to have beneficial effects on BP and gaseous signaling molecules in EH patients. However, further investigation is required to understand the exact mechanisms underlying these observations, and to confirm these results in a larger cohort.

    The aim of this research is to determine the effect of TAI or direct learning (DL) on student’s mathematics achievement viewed from spatial intelligence. This research was quasi experiment. The population was 10th grade senior high school students in Alor Regency on academic year of 2015/2016 chosen by stratified cluster random sampling. The data were collected through achievement and spatial intelligence test. The data were analyzed by two ways, ANOVA with unequal cell and scheffe test. This research showed that student’s mathematics achievement used in TAI had better results than DL models one. In spatial intelligence category, student’s mathematics achievement with high spatial intelligence has better result than the other spatial intelligence category and students with high spatial intelligence have better results than those with middle spatial intelligence category. At TAI, student’s mathematics achievement with high spatial intelligence has better result than those with the other spatial intelligence category and students with middle spatial intelligence have better results than students with low spatial intelligence. In DL model, student’s mathematics achievement with high and middle spatial intelligence has better result than those with low spatial intelligence, but students with high spatial intelligence and middle spatial intelligence have no significant difference. In each category of spatial intelligence and learning model, mathematics achievement has no significant difference.

    Antipsychotic drugs are limited in their ability to improve negative symptoms, quality of life, and medication adherence in patients with schizophrenia. The addition of nonpharmacological interventions like social skills training has a positive effect on medication adherence and decreases rehospitalization rates but is limited in improving patients' symptoms, aggressive behaviors, and quality of life. Aerobic exercise, especially Tai-chi, can potentially reduce psychopathological and negative symptoms, decrease aggressive behaviors, and improve quality of life. It is an ideal rehabilitation intervention for patients with schizophrenia. However, no study has investigated the effects of social skills training plus Tai-chi on outcomes among outpatients with schizophrenia. This study analyzes the effect of antipsychotics combined with community-based integrated interventions on outcomes of schizophrenia. In this study, a 24-session social skills training plus Tai-chi was used in community settings among patients with schizophrenia. A total of 244 patients were randomly assigned to medication treatment alone (MTA group) or community-based integrated intervention (CBII group), which accepted social skills training plus Tai-chi in addition to medication treatment. Generalized linear mixed models were used to evaluate the intervention effect (group effect), intervention effect over time (time effect), and interaction effect (group × time effect). t tests were used to evaluate between-group differences on clinical variables. Multiple linear regression analysis was used to analyze the differences between the intervention at 12 months and baseline for the Positive and Negative Syndrome Scale (PANSS) negative symptoms and quality of life-social domain. Compared with the MTA group, the CBII group had lower scores on PANSS (F = 17.312, p social domain of the World Health Organization Quality of Life Scale-Brief version (WHOQOL-BREF) from baseline to 12 months were significant

    Full Text Available One of the most fragile stratums of every society is the people with certain disabilities, especially educable mentally retarded children. Some of the most tangible difficulties of these people are seen in their perceptual and motional abilities (coordination, balance, atmospheric awareness, time awareness, physical awareness and sense of direction. Overcoming these inabilities requires the integration of environmental information and decision making for performance of a special function. The objective of the present research is to investigate the effects of eight weeks of Tai-Chi exercises on status parameters of Kyphosis and balance among educable mentally retarded children. The research sample is consisted of 30 educable mentally retarded children suffering from Kyphosis abnormality. The sample individuals were selected from welfare centers of Tehran. After selection of samples, prior and post to execution of the protocol, the individuals were measured in terms of Kyphosis angle, chest expansion, coefficient of Delmas, spine extension and static and dynamic balances respectively through flexible rulers, tape measure, stoke test and Y test. The educable mentally retarded children were assigned to two 15 individual groups of experimental (age average of 11.6 years; average height of 142.30; average weight of 39.26kg and control (age average of 11.06; height average of 139.83 and weight average of 35.86kg. The subjects of the experimental group were participated in an 8 week course of Tai-Chi exercises in three weekly 45 minute sessions. These exercises included a 10 minute warm-up, 30 minutes of Tai-Chi movements and 5 minutes of cool-down. During this time, the subjects of the control group were not incorporated into any exercise. By the use of the Shapiro-Wilk test, the normality of data distribution was investigated and approved. Also the Leon test was used for investigation of equality of the variances. Afterwards, descriptive statistics

    Ionospheric delay is one of the major sources of error in GPS positioning and navigation. This error in both pseudorange and phase ranges can vary depending on the location of observation, local time, season, solar cycle and geomagnetic activity. This effect can be practically removed using dual-frequency receivers. However, these types of receivers are very expensive and thus, impractical for most users. Therefore, for single-frequency receivers, ionosphere is usually modeled to attempt to remove this effect analytically. Numerous ionosphere models have been introduced in the past. Some of which are the Klobuchar (or broadcast) model and the global ionosphere map (GIM) provided by the International GNSS Service (IGS). In this paper, another model, called the TaiWan Ionosphere Model (TWIM) was used to correct this effect. TWIM is a three dimensional ionospheric electron (ne) density model derived from FormoSat3/COSMIC GPS Radio Occultation measurements, was used to calculate ionospheric delay for GPS single-frequency positioning. The ne profiles were used to calculate the slant TEC (STEC) between a receiver and each GPS satellite and correct the pseudorange single-frequency observations. The corrected pseudorange for every epoch was used to calculate the position of the receiver. Observations were made in a low-latitude location near one of the peaks of the equatorial anomaly. It was shown that TEC maps generated using TWIM exhibited detailed structure of the ionosphere, whereas Klobuchar and GIM only provided the basic diurnal and geographic features of the ionosphere. Also, it was shown that for static point positioning TWIM provides more accurate and more precise positioning than the Klobuchar and GIM models. That is, on the average, the horizontal accuracy, represented by the circular error probable (CEP), distance RMS (DRMS) and twice the DRMS (2DRMS), were better by 15-18% as compared with the CEP, DRMS and 2DRMS of uncorrected, Klobuchar and GIM.

    Full Text Available This paper is based on an ethnographic enquiry conducted over the last four years and shows the setting of a close interaction between hosts and guests in the White Tai villages in Mai Chau district, in the northwest uplands of Vietnam. The author argues that tourism is utilised as a medium to demonstrate a culture of hospitality. A new trend in tourism production and consumption is brought into discussion; in relation to this, this paper looks at what is really happening in the tourism spaces of the White Tai villages through the experiences not only of tourists but also of villagers. The author identifies several types of host-guest relationships and argues that there is a transformation of the host-guest relationship within these tourist spaces, a transformation evident in the new production and consumption practices of the market. Such relationships must be understood by looking beyond conceptions of commodification and politicisation of ethnicity. --- Basierend auf einer vierjährigen ethnographischen Feldforschung schildert dieser Beitrag die Interaktionen zwischen Bereisten und Reisenden anhand von White Tai-Dörfern im Mai Chau-Bezirk im nordwestlichen Hügelland Vietnams. Die Autorin argumentiert, dass Tourismus als Medium zur Demonstration von Gastfreundlichkeit eingesetzt werde. Neben einer Diskussion zu touristischer Pro- duktion und Konsum, werden in diesem Artikel auch die Erfahrungen und Wahrnehmungen der TouristInnen und DorfbewohnerInnen analysiert sowie verschiedene Typen von Beziehungen zwischen GastgeberInnen und Gästen identifiziert. Es wird dabei argumentiert, dass im Kontext touristischer Räume eine Transformation dieser Beziehungen stattfinde, die in den neuen Produktions- und Konsumpraktiken evident sei. Solche Beziehungen können nur verstanden werden, wenn ein altbekanntes Verständnis von Kommodifizierung und Politisierung von Ethnizität erweitert werde.

  11. Tai Ji Quan for the aging cancer survivor: Mitigating the accelerated development of disability, falls, and cardiovascular disease from cancer treatment

    Full Text Available Currently there are more than 13.7 million cancer survivors living in the U.S., and that figure is projected to increase by 31% in the next decade, adding another 4 million cancer survivors into the healthcare system. Cancer is largely a disease of aging, and the aging of the population will sharply raise the proportion of older cancer survivors, many of whom will be long-term survivors (5+ years post diagnosis. This review will address the potential utility of exercise to address three health problems that are of particular concern for the aging cancer survivor and the healthcare system, i.e., disability, falls, and cardiovascular disease, because the development of these age-related problems may be accelerated by cancer treatment. While there are many different modes of exercise that each produce specific adaptations, Tai Ji Quan may be a particularly suitable strategy to mitigate the development of age- and cancer-treatment-related problems. Based on studies in older adults without cancer, Tai Ji Quan produces musculoskeletal and cardiometabolic adaptations and is more easily performed by older adults due to its low energy cost and slower movement patterns. Since cancer survivors are mostly older, inactive, and often physically limited by the lingering side effects of treatment, they need to engage in safe, practical, and effective modes of exercise. The dearth of published controlled trials examining the efficacy of Tai Ji Quan to mitigate cancer-treatment-related musculoskeletal and cardiovascular side effects points to ample research opportunities to explore the application of this non-Western exercise modality to improve long-term outcomes for aging cancer survivors.

    Understanding the impacts of climate change and agricultural management practices on soil organic carbon (SOC) dynamics is critical for implementing optimal farming practices and maintaining agricultural productivity. This study examines the influence of climate and agricultural management on carbon sequestration potentials in Tai-Lake Paddy soils of China using the DeNitrification-DeComposition (DNDC) model, with a high-resolution soil database (1:50,000). Model simulations considered the effects of no tillage, increasing manure application, increasing/decreasing of N-fertilizer application and crop residues, water management, and climatic shifts in temperature and precipitation. We found that the carbon sequestration potential for the 2.32 Mha paddy soils of the Tai-Lake region varied from 4.71 to 44.31 Tg C during the period 2001-2019, with an annual average SOC changes ranged from 107 to 1005 kg C ha-1 yr-1. The sequestration potential significantly increased with increasing application of N-fertilizer, manure, conservation tillage, and crop residues. To increase soil C sequestration in this region, no-tillage and increasing of crop residue return to soils and manure application are recommended. Our analysis of climate impacts on SOC sequestration suggests that the rice paddies in this region will continue to be a carbon sink under future warming conditions. In addition, because the region’s annual precipitation (>1200 mm) is high, we also recommend reducing irrigation water use for these rice paddies to conserve freshwater in the Tai-Lake region.

Patients and methods: “Hidden elderly” is a term used to describe older adults who are socially isolated and refuse social participation. This pilot randomized controlled trial recruited 48 older adults aged 60 or above who did not engage in any social activity. They were randomized into tai chi qigong (n=24 and standard care control (n=24 groups. The former group underwent a three-month program of two 60-minute sessions each week, with the socially active volunteers paired up with them during practice. Standard care included regular home visits by social workers. Primary outcomes were assessed by means of the Lubben social network and De Jong Gieveld loneliness scales, and by a revised social support questionnaire. Secondary outcomes were covered by a mental health inventory and the Rosenberg self-esteem scale, and quality of life by using the 12-Item Short Form Health Survey. Data was collected at baseline, and at three and six months thereafter. Results: The generalized estimating equations model revealed general improvement in outcomes among participants on the tai chi qigong program. In particular, participants reported a significantly greater improvement on the loneliness scale (B=-1.32, 95% confidence interval [CI] -2.54 to -0.11, P=0.033 and the satisfaction component of the social support questionnaire (B=3.43, 95% CI 0.10–6.76, P=0.044 than the control group.

    Women with cancer are significantly more likely to fall than women without cancer placing them at higher risk of fall-related fractures, other injuries and disability. Currently, no evidence-based fall prevention strategies exist that specifically target female cancer survivors. The purpose of the GET FIT (Group Exercise Training for Functional Improvement after Treatment) trial is to compare the efficacy of two distinct types of exercise, tai chi versus strength training, to prevent falls in women who have completed treatment for cancer. The specific aims of this study are to: 1) Determine and compare the efficacy of both tai chi training and strength training to reduce falls in older female cancer survivors, 2) Determine the mechanism(s) by which tai chi and strength training each reduces falls and, 3) Determine whether or not the benefits of each intervention last after structured training stops. We will conduct a three-group, single-blind, parallel design, randomized controlled trial in women, aged 50–75 years old, who have completed chemotherapy for cancer comparing 1) tai chi 2) strength training and 3) a placebo control group of seated stretching exercise. Women will participate in supervised study programs twice per week for six months and will be followed for an additional six months after formal training stops. The primary outcome in this study is falls, which will be prospectively tracked by monthly self-report. Secondary outcomes are maximal leg strength measured by isokinetic dynamometry, postural stability measured by computerized dynamic posturography and physical function measured by the Physical Performance Battery, all measured at baseline, 3, 6 and 12 months. The sample for this trial (N=429, assuming 25% attrition) will provide adequate statistical power to detect at least a 47% reduction in the fall rate over 1 year by being in either of the 2 exercise groups versus the control group. The GET FIT trial will provide important new knowledge

    The current study was undertaken to evaluate Salmonella contamination in retail pork at major village markets of the Tai'an region, China. In total, 200 retail pork samples were collected from four village markets between June 2015 and February 2016, of which 69 samples (34.5%) were determined to be positive for Salmonella. Eleven serotypes were identified from the 69 Salmonella isolates, and Salmonella Derby was the most common (18 of 69, 26.1%), followed by Typhimurium (17 of 69, 24.6%) and Meleagridis (11 of 69, 15.9%). Antimicrobial susceptibility testing showed that antimicrobial resistance against tetracycline was the most prevalent (42 of 69, 60.9%), but antimicrobial resistance against both ceftriaxone and cefotaxime was 1.4% (1 of 69) and 2.9% (2 of 69), respectively. Multilocus sequence typing revealed that the 69 Salmonella isolates were divided into 11 sequence types (STs), among which ST40 (18 of 69, 26.1%) was the most common, followed by ST34 (15 of 69, 21.7%) and ST64 (13 of 69, 18.8%). Collectively, retail pork at village markets in the Tai'an region has a high Salmonella contamination rate, and these isolates exhibit broad-spectrum antimicrobial resistance. However, the absence of a dominant ST demonstrates that the Salmonella isolates from retail pork may be of diverse origins.

    Full Text Available To determine if Tai Chi (TC has an impact on long-range correlations and fractal-like scaling in gait stride time dynamics, previously shown to be associated with aging, neurodegenerative disease, and fall risk.Using Detrended Fluctuation Analysis (DFA, this study evaluated the impact of TC mind-body exercise training on stride time dynamics assessed during 10 minute bouts of overground walking. A hybrid study design investigated long-term effects of TC via a cross-sectional comparison of 27 TC experts (24.5 ± 11.8 yrs experience and 60 age- and gender matched TC-naïve older adults (50-70 yrs. Shorter-term effects of TC were assessed by randomly allocating TC-naïve participants to either 6 months of TC training or to a waitlist control. The alpha (α long-range scaling coefficient derived from DFA and gait speed were evaluated as outcomes.Cross-sectional comparisons using confounder adjusted linear models suggest that TC experts exhibited significantly greater long-range scaling of gait stride time dynamics compared with TC-naïve adults. Longitudinal random-slopes with shared baseline models accounting for multiple confounders suggest that the effects of shorter-term TC training on gait dynamics were not statistically significant, but trended in the same direction as longer-term effects although effect sizes were very small. In contrast, gait speed was unaffected in both cross-sectional and longitudinal comparisons.These preliminary findings suggest that fractal-like measures of gait health may be sufficiently precise to capture the positive effects of exercise in the form of Tai Chi, thus warranting further investigation. These results motivate larger and longer-duration trials, in both healthy and health-challenged populations, to further evaluate the potential of Tai Chi to restore age-related declines in gait dynamics.The randomized trial component of this study was registered at ClinicalTrials.gov (NCT01340365.

    In recent decades, the evidence supporting the physical and mental health benefits of holistic movement practices such as yoga and t'ai chi have become increasingly established. Consequently, investigating the participation prevalence and patterns of these practices is a relevant pursuit in the public health field. Few studies have provided population-level assessment of participation rates, however, and even fewer have focused on patterns over time. The purpose of this study was to examine participation prevalence and trends in yoga/Pilates and t'ai chi/qigong over a ten-year period in a nationally representative sample of Australians aged 15 years and over, with particular attention to sex and age. A secondary purpose was to juxtapose these findings with participation trends in traditional fitness activities over the same period. Data comprised modes and types of physical activity, age, and sex variables collected through the Exercise, Recreation and Sport Survey (ERASS), a series of independent cross-sectional Australia-wide surveys conducted yearly between 2001 and 2010. For each year, weighted population estimates were calculated for those participating in yoga/Pilates, t'ai chi/qigong, and fitness activities (e.g. aerobics, calisthenics). Linear regression and multiple logistic regression analyses were used to examine trends in prevalence rates over time and differences among sex and age (15-34; 35-54; 55+ years) groups, respectively. Average prevalence rates between 2001 and 2010 were 3.0% (95% CI 2.9-3.1) for yoga/Pilates, 0.6% (95% CI 0.5-0.6) for t'ai chi/qigong, and 19.2% (95% CI 18.9-19.4) for fitness activities. Across the decade, overall participation rates remained relatively stable for yoga/Pilates and t'ai chi/qigong, while increasing linearly for fitness activities. For both genders and in all three age groups, participation in fitness activities increased, whereas only in the 55+ age group was there a significant increase in yoga

    Higher age is associated to a variety of physical and mental disorders. Age-related changes in steroid secretion have been suggested to be an underlying mechanism leading to frailty, depression, and sexual dysfunction. However, Tai chi qigong and similar forms of exercise have been shown to improve a great variety of health-related parameters in older individuals. We examined 56 self-reporting healthy men actively practicing Tai chi qigong and/or self-defense Kung-fu and 55 age-matched self-reporting healthy controls. Saliva samples were obtained in a standardized procedure for subsequent quantification of circulating testosterone and cortisol levels. In addition, depressive symptoms, life satisfaction, and sexual health were assessesd via self-report questionnaires. Age was negatively associated with testosterone, while no association emerged for cortisol. Tai chi qigong and/or self-defense Kung-fu training was neither associated with testosterone nor cortisol. More weekly Tai chi qigong and/or self-defense Kung-fu training (4 or more times per week) was instead associated with a lower CT-ratio, less depressive symptoms, and higher life satisfaction compared to individuals, who trained only one to three times per week. More years of Tai chi qigong and/or self-defense Kung-fu training were associated with less depressive symptoms and higher life satisfaction but not with the CT-ratio. No significant associations emerged for Tai chi qigong and/or self-defense Kung-fu training and sexual health. When compared to the age-matched controls, there is a significant effect of Tai chi, qigong and/or self-defense Kung-fu on the CT-ratio. Contrast analyses revealed a significantly lower CT-ratio for the high training load group in contrast to the low training load group. Further, in contrast to the control group, the low training load group exhibits a significantly higher CT-ratio. For depression, contrast analyses revealed a significantly lower level of depression in the

    Full Text Available Organic tracer compounds, as well as organic carbon (OC, elemental carbon (EC, water-soluble organic carbon (WSOC, and stable carbon isotope ratios (δ13C of total carbon (TC have been investigated in aerosol samples collected during early and late periods of the Mount Tai eXperiment 2006 (MTX2006 field campaign in the North China Plain. Total solvent-extractable fractions were investigated by gas chromatography/mass spectrometry. More than 130 organic compounds were detected in the aerosol samples. They were grouped into twelve organic compound classes, including biomass burning tracers, biogenic primary sugars, biogenic secondary organic aerosol (SOA tracers, and anthropogenic tracers such as phthalates, hopanes and polycyclic aromatic hydrocarbons (PAHs. In early June when the field burning activities of wheat straws in the North China Plain were very active, the total identified organics (2090 ± 1170 ng m−3 were double those in late June (926 ± 574 ng m−3. All the compound classes were more abundant in early June than in late June, except phthalate esters, which were higher in late June. Levoglucosan (88–1210 ng m−3, mean 403 ng m−3 was found as the most abundant single compound in early June, while diisobutyl phthalate was the predominant species in late June. During the biomass-burning period in early June, the diurnal trends of most of the primary and secondary organic aerosol tracers were characterized by the concentration peaks observed at mid-night or in early morning, while in late June most of the organic species peaked in late afternoon. This suggests that smoke plumes from biomass burning can uplift the aerosol particulate matter to a certain altitude, which could be further transported to and encountered the summit of Mt.

    Daytime and night-time PM 1 and PM 2.5 samples were simultaneously collected at the summit of Mount Tai during summer and autumn 2014. The mass concentrations and chemical compositions were analysed to determine the temporal variations of PM 1 and PM 2.5 and their contributions to visibility impairment. In summer, the average mass concentrations of PM 1 and PM 2.5 were 38.16μg/m 3 and 53.33μg/m 3 , respectively. In autumn, the values were 42.75μg/m 3 and 59.16μg/m 3 . Water-soluble inorganic ions were the most abundant species in both PM 1 and PM 2.5 , followed by organic mass (OM). Among the major water-soluble ions, SO 4 2- and NH 4 + had higher concentrations in summer than in autumn, whereas the concentration of NO 3 - showed the opposite seasonal trend. Lower concentrations of organic carbon (OC), elemental carbon (EC) and water-soluble organic carbon (WSOC) were obtained in summer than in autumn. The water-soluble components (SO 4 2- , NO 3 - , NH 4 + and WSOC) showed a clear diurnal variation due to the specific meteorological conditions of Mount Tai. The water content in PM 1 and PM 2.5 was enhanced by the water-soluble components, especially NH 4 NO 3 . The decreased visibility resulted from the combined influence of particulate matter and relative humidity (RH). The threshold PM 2.5 concentration corresponding to a visibility of <10km was 56.60μg/m 3 , which decreased with an increase in RH. A revised IMPROVE equation was applied to estimate the light-extinction coefficient b ext , which was found to be lower for these chemicals in autumn (364Mm -1 ) than in summer (482Mm -1 ). (NH 4 ) 2 SO 4 made the largest contribution to b ext in both summer and autumn, with an average rate of 56.97%. OM (17.32%) and NH 4 NO 3 (15.13%) were also important contributors, with similar contribution rates. The contribution of NH 4 NO 3 to b ext was higher during summer, and OM contributions were higher during autumn. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available El trabajo titulado “El Tai-Chi, una alternativa para mejorar la concentración de la atención en los estudiantes” persigue como objetivo la concentración de la atención de los estudiantes mediante la práctica del Tai-Chi, para así demostrar que se concentra e influye en la esfera específica de la disociación de ideas, que tanto se pone de manifiesto sobre todo en los estudiantes con trastornos del comportamiento, los que se caracterizan por la combinación de un comportamiento hiperactivo y pobremente modulado con una marcada falta de atención y de continuidad en las tareas, manifestando una actividad desorganizada, mal regulada y excesiva. Normalmente estas dificultades persisten durante los años de escolaridad e incluso en la vida adulta, pero en muchos de los afectados se produce, con el paso de los años, una mejoría gradual de la hiperactividad y del déficit de la atención. En este empeño queremos proponer algunas herramientas de trabajo para los profesores que buscan alternativas para el desarrollo de la concentración de la atención en los escolares con trastornos del comportamiento, con el ánimo de que durante su vida ostenten un mayor aprovechamiento docente y puedan desempeñarse de una forma más útil en la sociedad. De lo anterior se deduce la gran necesidad de que la familia y la escuela coordinen y se planteen objetivos comunes en cuanto al desarrollo de la concentración de la atención en escolares con trastornos del comportamiento, puesto que los profesores en el proceso docente educativo tienen que tener en cuenta las características de estos para desarrollar en ellos estrategias de aprendizaje. Por lo que esta alternativa tratara de darle solución a uno de los problemas claves presentados en el estudiantado, es decir, una vía para eliminar la falta de concentración en las diferentes actividades que repercute en la formación general integral.

  5. Incorporation of Complex Hydrological and Socio-economic Factors for Non-point Source Pollution Control: A Case Study at the Yincungang Canal, the Lake Tai Basin of China

    It is increasingly realized that non-point pollution sources contribute significantly to water environment deterioration in China. Compared to developed countries, non-point source pollution in China has the unique characteristics of strong intensity and composition complexity due to its special socioeconomic conditions. First, more than 50% of its 1.3 billion people are rural. Sewage from the majority of the rural households is discharged either without or only with minimal treatment. The large amount of erratic rural sewage discharge is a significant source of water pollution. Second, China is plagued with serious agricultural pollution due to widespread improper application of fertilizers and pesticides. Finally, there lack sufficient disposal and recycling of rural wastes such as livestock manure and crop straws. Pollutant loads from various sources have far exceeded environmental assimilation capacity in many parts of China. The Lake Tai basin is one typical example. Lake Tai is the third largest freshwater lake in China. The basin is located in the highly developed and densely populated Yangtze River Delta. While accounting for 0.4% of its land area and 2.9% of its population, the Lake Tai basin generates more than 14% of China's Gross Domestic Production (GDP), and the basin's GDP per capita is 3.5 times as much as the state average. Lake Tai is vital to the basin's socio-economic development, providing multiple services including water supply for municipal, industrial, and agricultural needs, navigation, flood control, fishery, and tourism. Unfortunately, accompanied with the fast economic development is serious water environment deterioration in the Lake Tai basin. The lake is becoming increasingly eutrophied and has frequently suffered from cyanobacterial blooms in recent decades. Chinese government has made tremendous investment in order to mitigate water pollution conditions in the basin. Nevertheless, the trend of deteriorating water quality has yet to

    Fungi are ubiquitous throughout the near-surface atmosphere, where they represent an important component of primary biological aerosol particles. This study combined internal transcribed spacer region sequencing and quantitative real-time polymerase chain reaction (qPCR) to investigate the ambient fungi in fine (PM2. 5, 50 % cutoff aerodynamic diameter Da50 = 2.5 µm, geometric standard deviation of collection efficiency σg = 1.2) and submicron (PM1, Da50 = 1 µm, σg = 1.2) particles at the summit of Mt. Tai located in the North China Plain, China. Fungal abundance values were 9.4 × 104 and 1.3 × 105 copies m-3 in PM2. 5 and PM1, respectively. Most of the fungal sequences were from Ascomycota and Basidiomycota, which are known to actively discharge spores into the atmosphere. The fungal community showed a significant seasonal shift across different size fractions according to Metastats analysis and the Kruskal-Wallis rank sum test. The abundance of Glomerella and Zasmidium increased in larger particles in autumn, whereas Penicillium, Bullera, and Phaeosphaeria increased in smaller particles in winter. Environmental factors, namely Ca2+, humidity, and temperature, were found to be crucial for the seasonal variation in the fungal community. This study might serve as an important reference for fungal contribution to primary biological aerosol particles.

    Reproductive toxicity of organic extracts of the surface water from the Tai section of the Yangtze River was assessed by in vitro cytotoxity assays and selected persistent organic pollutants including PCBs, OCPs and PAHs were quantified by instrumental analysis. Eleven of the US EPA priority PAHs were detected. Individual PAHs were found to range from 0.7 to 20 ng/L. Concentrations of BaP did not exceed the national drinking water source quality standard of China. However, a 286-fold concentrated organic extract induced significant reproductive toxicity in adult male rats. The morphology of cells, MTT assay and LDH release assay were all affected by exposure to the organic extracts of water. The results of the reproductive toxicity indicated that PAHs posed the greatest risk of the chemicals studied. The compounds present in the water could be bioconcentrated and result in adverse effects. - Highlights: → Only 11 PAHs of US EPA priority PAHs were detected in surface water the Yangtze River. → Level of BaP didn't exceed national drinking water source quality standard of China. → 286-fold concentrated organic extracts induced great reproductive toxicity in rats. → PAHs posed the greatest risk of the chemicals studied. → The compounds in the water could be bioconcentrated and result in adverse effects. - In vitro bioassay responses observed in Yangtze River source water extracts showed great reproductive toxicity, and PAHs were responsible.

    Bacteria are widely distributed in atmospheric aerosols and are indispensable components of clouds, playing an important role in the atmospheric hydrological cycle. However, limited information is available about the bacterial community structure and function, especially for the increasing air pollution in the North China Plain. Here, we present a comprehensive characterization of bacterial community composition, function, variation, and environmental influence for cloud water collected at Mt Tai from 24 July to 23 August 2014. Using Miseq 16S rRNA gene sequencing, the highly diverse bacterial community in cloud water and the predominant phyla of Proteobacteria, Bacteroidetes, Cyanobacteria, and Firmicutes were investigated. Bacteria that survive at low temperature, radiation, and poor nutrient conditions were found in cloud water, suggesting adaption to an extreme environment. The bacterial gene functions predicted from the 16S rRNA gene using the Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) suggested that the pathways related to metabolism and disease infections were significantly correlated with the predominant genera. The abundant genera Acinetobacter, Stenotrophomonas, Pseudomonas, and Empedobacter originated from a wide range of habitats including cloud condensation nuclei and ice nuclei active species, opportunistic pathogens, and functional species, demonstrating the importance of ecology and health in cloud water. Cluster analysis including hierarchical cluster (Hcluster) and principal coordinate analysis (PCoA) indicated a significant disparity between polluted and non-polluted samples. Linear discriminant analysis effect size (LEfSe) demonstrated that potential pathogens were enriched in the polluted cloud samples, whereas the diverse ecological function groups were significant in the non-polluted samples. Discrepant community structure determined by redundancy analysis (RDA) indicated that the major ions in

    Purpose Cognitive behavioral therapy for insomnia (CBT-I) and Tai Chi Chih (TCC), a movement meditation, improve insomnia symptoms. Here, we evaluated whether TCC is noninferior to CBT-I for the treatment of insomnia in survivors of breast cancer. Patients and Methods This was a randomized, partially blinded, noninferiority trial that involved survivors of breast cancer with insomnia who were recruited from the Los Angeles community from April 2008 to July 2012. After a 2-month phase-in period with repeated baseline assessment, participants were randomly assigned to 3 months of CBT-I or TCC and evaluated at months 2, 3 (post-treatment), 6, and 15 (follow-up). Primary outcome was insomnia treatment response-that is, marked clinical improvement of symptoms by the Pittsburgh Sleep Quality Index-at 15 months. Secondary outcomes were clinician-assessed remission of insomnia; sleep quality; total sleep time, sleep onset latency, sleep efficiency, and awake after sleep onset, derived from sleep diaries; polysomnography; and symptoms of fatigue, sleepiness, and depression. Results Of 145 participants who were screened, 90 were randomly assigned (CBT-I: n = 45; TCC: n = 45). The proportion of participants who showed insomnia treatment response at 15 months was 43.7% and 46.7% in CBT-I and TCC, respectively. Tests of noninferiority showed that TCC was noninferior to CBT-I at 15 months ( P = .02) and at months 3 ( P = .02) and 6 ( P insomnia remission was 46.2% and 37.9% in CBT-I and TCC, respectively. CBT-I and TCC groups showed robust improvements in sleep quality, sleep diary measures, and related symptoms (all P insomnia. TCC, a mindful movement meditation, was found to be statistically noninferior to CBT-I, the gold standard for behavioral treatment of insomnia.

    Based on the remote sensing data in 2000, 2005, and 2010, this paper analyzed the variation trends of the land use type and landscape pattern in Daiyue District of Tai' an City from 2000 to 2010. The ecological risk index was built, that of the District was re-sampled and spatially interpolated, and the spatiotemporal pattern of the ecological risk in the rural-urban ecotone of the District was analyzed. In 2000-2010, the main variation trend of the land use type in the District was the shift from natural landscape to artificial landscape. The intensity of human disturbance was larger in cultivated land, garden plot, and forestland than in other landscape types, while the human disturbance in water area was smaller. The ecological loss degree of cultivated land and water area decreased somewhat, while that of the other land use types presented an increasing trend. The ecological risk distribution in the District was discrete in 2000 and 2010, but most centralized in 2005. The ecological risk of each ecological risk sub-area had an increasing trend in 2000-2005, but was in adverse in 2005-2010. In 2000-2010, the ecological risk of the District was mainly at medium level. Spatially, the distribution of the ecological risk in the District had an obvious differentiation, with an overall diffusive increasing from forestland as the center to the surrounding areas. In the District, the ecological risk was mainly at medium and higher levels, the area with lower ecological risk had an obvious dynamic change, while that with the lowest and highest ecological risk had less change.

    To understand the source and atmospheric behaviour of low molecular weight monocarboxylic acids (monoacids), gaseous (G) and particulate (P) organic acids were collected at the summit of Mt.

Particulate organic acids were collected with neutral quartz filter whereas gaseous organic acids were collected with KOH-impregnated quartz filter. Normal (C1-C10), branched (iC4-iC6), hydroxy (lactic and glycolic), and aromatic (benzoic) monoacids were determined with a capillary gas chromatography employing p-bromophenacyl esters. We found acetic acid as the most abundant gas-phase species whereas formic acid is the dominant particle-phase species. Concentrations of formic (G/P 1 570/1 410 ng m-3) and acetic (3 960/1 120 ng m-3) acids significantly increased during the enhanced field burning of agricultural wastes. Concentrations of formic and acetic acids in daytime were found to increase in both G and P phases with those of K+, a field-burning tracer (r = 0.32-0.64). Primary emission and secondary formation of acetic acid is linked with field burning of agricultural wastes. In addition, we found that particle-phase fractions (Fp = P/(G + P)) of formic (0.50) and acetic (0.31) acids are significantly high, indicating that semi-volatile organic acids largely exist as particles. Field burning of agricultural wastes may play an important role in the formation of particulate monoacids in the NCP. High levels (917 ng m-3) of particle-phase lactic acid, which is characteristic of microorganisms, suggest that microbial activity associated with terrestrial ecosystem significantly contributes to the formation of organic aerosols.

    Background Diminished control of standing balance, traditionally indicated by greater postural sway magnitude and speed, is associated with falls in older adults. Tai Chi (TC) is a multisystem intervention that reduces fall risk, yet its impact on sway measures vary considerably. We hypothesized that TC improves the integrated function of multiple control systems influencing balance, quantifiable by the multi-scale “complexity” of postural sway fluctuations. Objectives To evaluate both traditional and complexity-based measures of sway to characterize the short- and potential long-term effects of TC training on postural control and the relationships between sway measures and physical function in healthy older adults. Methods A cross-sectional comparison of standing postural sway in healthy TC-naïve and TC-expert (24.5±12 yrs experience) adults. TC-naïve participants then completed a 6-month, two-arm, wait-list randomized clinical trial of TC training. Postural sway was assessed before and after the training during standing on a force-plate with eyes-open (EO) and eyes-closed (EC). Anterior-posterior (AP) and medio-lateral (ML) sway speed, magnitude, and complexity (quantified by multiscale entropy) were calculated. Single-legged standing time and Timed-Up–and-Go tests characterized physical function. Results At baseline, compared to TC-naïve adults (n = 60, age 64.5±7.5 yrs), TC-experts (n = 27, age 62.8±7.5 yrs) exhibited greater complexity of sway in the AP EC (P = 0.023), ML EO (Padults.

    Older cancer survivors are a vulnerable population due to an increased risk for chronic diseases (e.g., cardiovascular disease) compounded with treatment late-effects and declines in physical functioning. Therefore, interventions that reduce chronic disease risk factors (i.e., blood pressure, chronic inflammation, and cortisol) are important in this population. Tai chi chih (TCC) is a mind-body exercise associated with reductions in chronic disease risk factors, but has not been examined with older cancer survivors. In a feasibility randomized controlled trial of TCC, we examined secondary outcomes of blood pressure, salivary cortisol, and inflammatory cytokines (interleukin (IL)-6, IL-12, tumor necrosis factor-α, IL-10, IL-4) due to their implications in chronic diseases. Sixty-three senior female cancer survivors (M age = 67 years, SD = 7.15) with physical functioning limitations (SF-12 physical functioning ≤80 or role-physical ≤72) were randomized to 12-weeks (60-min, three times a week) of TCC or Health Education control (HEC) classes. Resting blood pressure, 1-day salivary cortisol samples, and fasting plasma samples for cytokine multiplex assays were collected at baseline and 1-week post-intervention. Controlling for baseline values, the TCC group had significantly lower systolic blood pressure (SBP, p = 0.002) and cortisol area-under-curve (AUC, p = 0.02) at post-intervention than the HEC group. There was no intervention effect on inflammatory cytokines (p's > 0.05). This TCC feasibility trial was associated with significant reductions in SBP and cortisol AUC in senior female cancer survivors. Larger, definitive trials are needed to confirm these findings. Senior survivors' have an increased risk for chronic diseases; however, TCC interventions may help reduce associated risk factors.

More than a quarter of adults with cognitive impairment experience sleep disturbance. The objective of this pilot study was to evaluate the preliminary effects of tai chi qigong (TCQ on improving the night-time sleep quality of older adults with cognitive impairment. Participants: Older adults with cognitive impairment who complain of sleep disturbance. Methods: A randomized controlled trial with two groups. Fifty-two subjects were recruited from two district elderly community centers and randomly assigned to either the TCQ group (n=27 or the control group (n=25. The intervention group received TCQ training consisting of two 60-minute sessions each week for 2 months. The control group was advised to maintain their usual activities. Sleep quality was measured by the Chinese Pittsburgh Sleep Quality Index. Quality of life was measured by Short-form 12, cognitive functions measured by mini-mental state examination, and subjective memory deficits measured by the memory inventory for Chinese. Results: Data were collected at baseline, 2 months, and 6 months. Significant results were noted at 6 months in the Chinese Pittsburgh Sleep Quality Index global score (P=0.004, sleep duration (P=0.003, habitual sleep efficiency (P=0.002, and the Short-form 12 mental health component (P<0.001. The TCQ participants reported better sleep quality and a better (quality of life mental health component than the control group.

    Osteoporosis (OP) has been defined as a degenerative bone disease characterised by low bone mass and microstructural deterioration of bone tissue, leading to fragility and an increased risk of fractures, especially of the hip, spine and wrist. Exercise has been shown to benefit the maintenance of bone health and improvement of muscle strength, balance and coordination, thereby reducing the risk of falls and fractures. However, prior findings regarding the optimal types and regimens of exercise for treating low bone mineral density (BMD) in elderly people are not consistent. As an important component of traditional Chinese Qigong exercises, Tai Chi (TC) is an ancient art and science of healthcare derived from the martial arts. The objective of this study is to attempt to conduct a systematic review and meta-analysis of the existing studies on TC exercise as an intervention for the prevention or treatment of OP in elderly adults and to draw more useful conclusions regarding the safety and the effectiveness of TC in preventing or treating OP. Eight electronic databases (Science Citation Index, PubMed Database, Embase (Ovid) Database, the Cochrane Central Register of Controlled Trials, and Chinese databases, including Chinese BioMedical Database, China National Knowledge Infrastructure, Wanfang database and the Chongqing VIP Chinese Science and Technology Periodical Database) will be searched from the beginning of each database to 1 April 2018. Potential outcomes of interest will include rates of fractures or falls, BMD at the total hip and the total spine, bone formation biomarkers, bone resorption biomarkers, bone biomarkers, health-related quality of life and adverse events. Only randomised controlled trials comparing TC exercise against each other or non-intervention will be included. The Cochrane risk of bias assessment tool will be used for quality assessment. Ethical approval is not required as the study will be a review of existing studies. This review may help

    Jiao-Tai-Wan (JTW), composed of Rhizome Coptidis and Cortex Cinnamomi, is a classical traditional Chinese prescription for treating insomnia. Several in vivo studies have concluded that JTW could exert its therapeutical effect in insomnia rats. However, the specific mechanism is still unclear. The present study aimed to explore the effect of JTW on sleep in obesity-resistant (OR) rats with chronic partial sleep deprivation (PSD) and to clarify its possible mechanism. JTW was prepared and the main components contained in the granules were identified by 3D-High Performance Liquid Chromatography (3D-HPLC) assay. The Male Sprague-Dawley (SD) rats underwent 4 h PSD by environmental noise and the treatment with low and high doses of JTW orally for 4 weeks, respectively. Then sleep structure was analyzed by electroencephalographic (EEG). Inflammation markers including high-sensitivity C reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels were examined in the rat plasma. Meanwhile, metabolic parameters as body weight increase rate, fasting plasma glucose (FPG), fasting insulin (FINS) levels and insulin resistance index (HOMA-IR) were measured. The expressions of clock gene cryptochromes (Cry1 and Cry2) and inflammation gene nuclear factor-κB (NF-κB) in peripheral blood monocyte cells (PBMC) were also determined. The result showed that the administration of JTW significantly increased total sleep time and total slow wave sleep (SWS) time in OR rats with PSD. Furthermore, the treatment with JTW reversed the increase in the markers of systemic inflammation and insulin resistance caused by sleep loss. These changes were also associated with the up-regulation of Cry1 mRNA and Cry 2 mRNA and the down-regulation of NF-κB mRNA expression in PBMC. This study suggests that JTW has the beneficial effects of improving sleep, inflammation and insulin sensitivity. The mechanism appears to be related to the modulation of circadian clock and

We randomized 100 patients with chronic systolic HF (NYHA Class 1-3, ejection fraction≤40%) to a 12-week group TC program or an education control. At 12-weeks, semi-structured interviews were conducted on a random subset (n = 32; n = 17 in TC, n = 15 in control), audiorecorded and transcribed verbatim. Two independent reviewers extracted information using grounded-theory methods for emergent themes. We explored similarities and differences in themes/sub-themes between the groups, and examined qualitative association with changes from baseline to post-intervention in previously reported quantitative measures (e.g., Minnesota Living with HF, Cardiac Exercise Self Efficacy and Profile of Mood States). The mean age (±SD) of participants was 68±9 years, baseline ejection fraction 29±7%, and median New York Heart Association class 2 HF. We idenitifed themes related to the patient's experience of illness, perceptions of self, and relationship to others. Specific psychosocial and physical benefits were described. Common themes emerged from both groups including: social support and self-efficacy related to activity/exercise and diet. The tai chi group, however, also exhibited a more global empowerment and perceived control. Additional themes in TC included mindfulness/self-awareness, decreased stress reactivity, and renewed social role. These themes mirrored improvements in previously reported quantitative measures (quality-of-life, self-efficacy, and mood) in TC compared to control. Patients in TC also reported physical benefits (e.g., decreased pain, improved energy, endurance, flexibility). Positive themes emerged from both groups, although there were qualitative differences in concepts of self-efficacy and perceived control

    Tai Chi (TC) is a form of low to moderate physical activity that has been shown to significantly impact health and functional fitness among older adults; the impact of TC on the health and functional fitness of older adults with arthritis is not well understood. The purpose of this study was to assess the effectiveness of a 16-week TC intervention for improving functional fitness and self-reported general health among older adults with arthritis who were born outside Canada and were residing in low-income neighborhoods. A 16-week intervention was conducted among older adults residing in 1 of 2 specified low-income neighborhoods in Canada. The analysis was limited to those who self-reported having arthritis (n = 102). Participants were encouraged to attend 2 moderate-intensity TC sessions per week for a total of 120 minutes. Functional fitness and health were assessed at baseline and at 16 weeks. Average attendance was 1.1 sessions per week. Functional fitness assessment results indicated that right-hand grip strength (25.6 ± 8.2 to 26.7 ± 7.8 kg), left-hand grip strength (24.9 ± 7.3 to 26.8 ± 7.1 kg), 30-second arm curl (15.6 ± 5.0 to 18.6 ± 5.7 repetitions/30 s), Timed Up-and-Go (7.4 ± 2.6 to 6.9 ± 2.6 s), and 30-second chair stand (12.0 ± 3.9 to 15.4 ± 5.8 s) improved significantly (P health (61.5 ± 20.9 to 66.0 ± 20.4; P = 0.03), vitality (61.5 ± 18.9 to 67.5 ± 20.2; P = 0.008), and mental health (74.3 ± 16.5 to 78.5 ± 17.7; P = 0.04) also improved significantly over the intervention period. Improvements in physical health and physical function scores were clinically meaningful. Participating in TC for 16 weeks led to significant improvements in functional fitness and components of physical and mental health among older adults with self-reported arthritis. Tai Chi seems to be a valuable mode of physical activity for this population.

    Cognitive decline amongst older adults is a significant public health concern. There is growing interest in behavioral interventions, including exercise, for improving cognition. Studies to date suggest tai chi (TC) may be a safe and potentially effective exercise for preserving cognitive function with aging; however, its short-term and potential long-term impact on physically active, healthy adults is unclear. To compare differences in cognitive function among long-term TC expert practitioners and age-matched and gender-matched TC-naïve adults and to determine the effects of short-term TC training on measures of cognitive function in healthy, nonsedentary adults. A hybrid design including an observational comparison and a 2-arm randomized clinical trial (RCT). Healthy, nonsedentary, TC-naive adults (50 y-79 y) and age-matched and gender-matched long-term TC experts. A cross-sectional comparison of cognitive function in healthy TC-naïve (n=60) and TC expert (24.5 y ÷ 12 y experience; n=27) adults: TC-naïve adults then completed a 6-month, 2-arm, wait-list randomized clinical trial of TC training. Six measures of cognitive function were assessed for both cross-sectional and longitudinal comparisons. TC experts exhibited trends towards better scores on all cognitive measures, significantly so for category fluency (P=.01), as well as a composite z score summarizing all 6 cognitive assessments (P=.03). In contrast, random assignment to 6 months of TC training in TC-naïve adults did not significantly improve any measures of cognitive function. In healthy nonsedentary adults, long-term TC training may help preserve cognitive function; however, the effect of short-term TC training in healthy adults remains unclear.

    Full Text Available Age-related cognitive decline is a significant public health concern. Recently, non-pharmacological methods, such as physical activity and mental training practices, have emerged as promising low-cost methods to slow the progression of age-related memory decline. In this study, we investigated if Tai Chi Chuan (TCC and Baduanjin modulated the fractional amplitude of low-frequency fluctuations (fALFF in different frequency bands (low-frequency: 0.01–0.08 Hz; slow-5: 0.01–0.027 Hz; slow-4: 0.027–0.073 Hz and improved memory function. Older adults were recruited for the randomized study. Participants in the TCC and Baduanjin groups received 12 weeks of training (1 h/day for 5 days/week. Participants in the control group received basic health education. Each subject participated in memory tests and fMRI scans at the beginning and end of the experiment. We found that compared to the control group: (1 TCC and Baduanjin groups demonstrated significant improvements in memory function; (2 TCC increased fALFF in the dorsolateral prefrontal cortex (DLPFC in the slow-5 and low-frequency bands; and (3 Baduanjin increased fALFF in the medial PFC in the slow-5 and low-frequency bands. This increase was positively associated with memory function improvement in the slow-5 and low-frequency bands across the TCC and Baduanjin groups. Our results suggest that TCC and Baduanjin may work through different brain mechanisms to prevent memory decline due to aging.

    This paper discusses simple measuring methods for water quality. There are various purposes for measuring water quality. It is not necessary to measure the water quality in an official way by taking a lot of labor and cost. Simple measuring methods are often adopted. By applying simple methods, measuring points and frequency of main discharge processes can be increased, resulting in the detailed evaluation and monitoring. Easy safety check for earth filling waste and soil pollutants is realized. Daily inspection and atmospheric measurements at accidents and disasters are easily promoted. The simple methods require easy and rapid operation, sensibility, accuracy and reproducibility suitable for the purpose, small size apparatus, low cost for measurements, and safety against used harmful matters. Coloring reaction is utilized for most of the measuring principles of simple methods, which include tests using test papers, pack tests, colorimetric tests, and tests using photoelectric colorimeter. The bacteria detection includes titration methods using dropping bottles, tablets and syringes, and tests using test papers. A measuring kit for the enzyme immunity method is commercialized. Cooperation of experts, measuring operators at the site and citizens is also indispensable. 7 refs., 3 figs., 2 tabs.

However, an inquisitive reader must ask the following questions: Can Kuang-i chi, a medieval collection of tales of encounters with the other world by the minor T’ang Dynasty official Tai Fu 戴孚 (fl. 760-780, chin-shih 757, be used for the purpose of the study of religious culture? How? and to what extent? What approaches would be effective in inquiring such a text and what kinds of conclusions can be drawn? Though not explicitly setting forth these questions, Dudbridge’s work serves as answers to them through explicitly defining the nature of Kuang-i chi to his study, discarding conventional categories and establishing new ones in his analysis, and associating Kuang-i chi to the “vernacular,” instead of official, or “centralized,” religious culture (p.63-4. Using a sharp historical focus on the collection, Dudbridge concentrates on the dynamics of change in religious practices of T’ang Dynasty that is rooted and reflected in such a vernacular religious culture....

    The present paper outlines the present situation of environment of developing countries, factors causing environmental devastation, and the influence in the international linkage as described in 1992 White Paper on Environment. The present environmental devastation is originated from national poverty. In general, as the results of imposing excessive pressure on the natural environment accompanying the increase of population or causing urban pollution due to the movement or densification of population, poverty brings about the reduction and devastation of forest, deterioration of soil, desertification, contamination of air and rivers, causing miserable situation. Prawn culture as primary export industry damages mangrove woods, and causes water pollution. Industrial development is rapidly spreading pollution of water and air. As for international relations, the net transfer amount of money in the flow of funds between advanced countries and developing countries is in the direction from the latter to the former due to payment of debts. In enforcing direct investment or overseas development aid projects, advanced countries must be aware of their responsibility, make efforts in grasping the situations of aided countries and perform sufficient environmental assessment. 5 refs., 8 figs., 11 tabs.

    For Laos, Bangladesh, Malaysia and Vietnam, survey was conducted to promote the introduction and spread of renewable energy, mainly the photovoltaic power generation. Relating to the solar radiation, the amount in the four countries is much higher than that in Japan, 3.4kWh/m{sup 2}/day on average. The countries are areas suitable for the photovoltaic power generation. As to the wind velocity, the area where the wind velocity is higher than 5m/second, which enables the introduction of the wind power generation, is limited to the south/west of Bangladesh, Malaysia, and the coastal part and islands in Vietnam. The wind power generation is being used in Malaysia and Vietnam. As for the precipitation, it rains concentratedly in the rainy season, and therefore, it is difficult to stably secure energy through the year by the small-scale hydroelectric power generation. In Vietnam, however, resident individuals eagerly introduce the small-scale hydroelectric power generation, and about 20,000kW is now in operation. Concerning the introduction of the photovoltaic power generation, Bangladesh is in a state of working out a master plan, Laos is in a state of drawing up a plan for the spread, and Malaysia and Vietnam are in a state of the verification.

    Energy conservation is considered the most realistic measure against the problem of the global warming for the time being. Developing countries consume about 30% of the energy consumed in the world. Although their absolute consumption amount is little at the moment, their energy consumption is increasing year after year. Efficiency of their energy utilization is low because compared with advanced countries their equipments are of old type and their technologies are behind the times. It is, therefore, estimated possible to conserve energy by 30% with e improvements and plant and equipment investments. It is very effective to introduce Japanese advanced energy conservation technologies to these countries through international cooperation. In fact investigation commissions composed of experts have been dispatched to Thailand, China and Argentine, experts have been dispatched to foreign countries to stay there for several years and give assistance, trainees have been received, and study and training meetings have been held already. Seminars with Japanese lecturers have been also held in many foreign countries since 1983. As for the future prospect, establishment of core organizations as the base of technologies and human resources in foreign countries for the further promotion of assistance is expected. 7 figs.

    As for the real GDP growth rate in India, the real GDP per capita during 1980-1993 increased 2.9% on annual average, but that in China did 8.0%. India has largely been behind China in the economic growth, but since the liberalization of economy in 1991, the Indian economy has remarkably been developed. It is predicted that the real GDP during 1993-2010 will be 5-6% on annual average. The difference in GDP increase between India and China is caused by differences in energy conservation, speed of conversion from non-commercial energy to commercial energy, serviceability of the industrial structure, etc. It is predicted that the primary energy consumption will grow on the level of China. The oil demand will grow 4-6% in China and 5-6% in India in 1993-2010, showing more increase in India. For oil import to India to exceed 1 million B/D in 2000, it is necessary to clear the ceiling of the international balance. For India to become a big country corresponding to its population size, a lot of difficulties should be overcome. 49 refs., 104 figs., 62 tabs.

    Anfo (Ammonium Nitrate and Fuel Oil)is an explosive consisting of prill ammonium nitrate and light oil that immediately spread across the world upon its debut in the U.S. around 1956, but the details of its birth, for example the name of its inventor, are not known. Granular ammonium nitrate is in production, with its porosity enhanced to elevate oil absorption efficiency to the level for the nitrate to be proper as the material for the anfo by adjusting the water content at approximately 4% in the ammonium nitrate mother liquid before corning. Efforts are being exerted by manufacturers to improve the drying process to remove excess water efficiently from granular ammonium nitrate. In Japan, industrial production of prill ammonium nitrate for the anfo began in 1964. Since then, the problem of anfo sensitivity to detonation has been solved by adjusting the oil absorption rate of prill ammonium nitrate to be in the range of 10-12%, and the problem of ammonium nitrate solidification has been solved by the development of a solidification preventing technology that utilizes solidification preventing agents based on organic surface active agents (while inorganic anti-bonding agents are in popular use in the U.S. and Europe)

    The paper arranged the present situation and the problems of environmental cooperation for developing countries, and studied based thereon how to cooperate in environmental protection for developing countries in the future. At the same time, it arranged the problems/subjects posed when environment-related companies in Japan try to transfer environmental technology to developing countries, for the purpose of using them as data in studying possibility of reviewing the environmental cooperation presently conducted. A view on environmental cooperation is that as security of mankind, it is necessary to help developing countries in technology/knowledge/fund. However, a trial calculation indicated that the initial investment of 11.1 trillion yen is needed only for desulfurization and water treatment in China and ASEAN countries. Such a huge amount of money cannot be paid at all even by developed countries. As the support of environmental protection measures, the one also including energy and resource is needed. Further, the support of environmental protection measures should be the one that has the exhibition effect and influential effect, promotes efforts of developing countries' own, and pushes independent environmental measures forward. From this point of view, a study was made on what the details of the environmental cooperation should be like. (NEDO)

    The olfactory cell is the most prominent chemical sensor to detect various kinds of external chemical substances with high sensibility. Consequently, on the model of such an organic chemical sensor mechanism, an artificial membrane with functions to detect and distinguish various chemical substances has been developed. In this study, a test using a lipid bimolecular membrane was carried out. As a result, it was found that the lipid bimolecular membrane showed membrane potential changes responding to various odorants. The mambrane with proper lipid composition presented almost the same sensibility to odorants as an olfactory organ. Response characteristic against various odors changed greatly due to the lipid composition and the addition of protein. It was also found that various odors can be discriminated by analyzing response information obtained from a lot of mambranes with different compositions Such ideas can be applied to the odor discrimination of the artificial membrane sensor. 14 refs., 13 figs.

    Due to the rapid economy growth and industry development in China, the map of industry and economy in Asian countries has been greatly changing. The technology, which has supported Japan's industrial development, is characterized by the improvements of original technologies introduced from Europe and the United States. On the other hand, Korea has problems of creating the original and individual production technology and its basis. The industrial technology in China at present has problems which are accompanied with the conversion from the planned economy system to the market economy system. However, Chinese people having a tradition of 'link of three parts' seem to understand the Japanese style management policy well. Japan has played a role as 'world's center of manufacturing' by using its excellent production technology. In the future, China is considered to play a role as the 'world's center of manufacturing,' due to its huge domestic market, cheap and rich manpower, and excellent potential capacity of industrial technology. In Japan, it is emphasized that an industrial society system should be reconstructed, in which excellent individuality and talent can be made good use of. 6 refs., 1 fig.

    Hongkong Route 3 construction under the BOT scheme (covering the basic plan, design, and construction, and the management of the completed tunnel as a private, toll facility) is described. The new route aims at dealing with aggravating traffic conditions as part of the major highway network joining Hongkong and Guanzhou, China proper. It is a dual three lane system, consisting of a 3.7km-long road tunnel, a 1.5km-long southern approach, and a 6.3km-long northern approach. Geologically speaking, the tunnel section as a whole is on a relatively hard and stable basement made of fine-grain granite and granitic diorite. Also introduced in this report are the project-executing organization and the flow of tendering under the BOT scheme. Since the shortening of the construction time is quite important in the 30-year BOT franchise period, rapid boring technologies were introduced into tunnel excavation. The 5.6m long-hole blasting enabled a maximum monthly progress of 460m. For the assurance of high boring accuracy and cycle time reduction, a fully automatic boring machine was adopted for speedy positioning and marking. An emulsion-type explosive was used, which can be pump-fed under pressure, for shortening the charging time. 5 figs.

    Full Text Available Background. Stroke is a major healthcare problem with serious long-term disability and is one of the leading causes of death in the world. Prevention of stroke is considered an important strategy. Methods. Seven electronic databases were searched. Results. 36 eligible studies with a total of 2393 participants were identified. Primary outcome measures, TCC exercise combined with other intervention had a significant effect on decreasing the incidence of nonfatal stroke (n=185, RR = 0.11, 95% CI 0.01 to 0.85, P=0.03 and CCD (n=125, RR = 0.33, 95% CI 0.11 to 0.96, P=0.04. For the risk factors of stroke, pooled analysis demonstrated that TCC exercise was associated with lower body weight, BMI, FBG level, and decreasing SBP, DBP, plasma TC, and LDL-C level regardless of the intervention period less than half a year or more than one year and significantly raised HDL-C level in comparison to nonintervention. Compared with other treatments, TCC intervention on the basis of the same other treatments in patients with chronic disease also showed the beneficial effect on lowering blood pressure. Conclusion. The present systematic review indicates that TCC exercise is beneficially associated with the primary prevention of stroke in middle-aged and elderly adults by inversing the high risk factors of stroke.

    This paper describes results of the rock magnetic survey mainly including measurement of magnetic susceptibility conducted in the northern Pakistan from 1992 to 1997. Magnetic characteristics in Himalaya-Karakoram ranges and prospective ore deposits are also described. Magnetic susceptibility data measured in this district were summarized as a frequency map in each geological block. Granitoids in the northern part of Kohistan batholith and granitoids of Ladakh batholith showed remarkably high magnetic susceptibility values, which suggested they are magnetite-series magmatism. It has been known that magnetite-series magmatism often accompanies sulfide-forming mineral resources, which suggests high potentiality of abundant mineral resources containing Mo, Cu, Pb, Zn, Ag and Au. From the results of the magnetic susceptibility measurements and the above-mentioned models, accordingly, it can be pointed out that the northern part of Kohistan batholith, the distribution area of Ladakh batholith, and surrounding areas are promising targets for mineral resources exploration in the Himalaya-Karakoram ranges, northern Pakistan. 5 refs., 3 figs.

    Xiaobing Chen

    Full Text Available Chinese mitten crab (CMC, Eriocheir sinensis is an economically valuable species in South-East Asia that has been widely farmed in China. Characterization of the intestinal bacterial diversity of CMC will provide insights into the aquaculturing of CMCs. Based on the analysis of cloned 16S rRNA genes from culture-independent CMC gut bacteria, 124 out of 128 different clones reveal >95% nucleotide similarity to the species belonging to the four phyla of Tenericutes, Bacteroidetes, Firmicutes and Proteobacteria; one clone shows 91% sequence similarity to the member of TM7 (a candidate phylum without cultured representatives. Fluorescent in situ hybridization also reveals the abundance of Bacteroidetes in crab intestine. Electron micrographs show that spherical and filamentous bacteria are closely associated with the microvillus brush border of the midgut epithelium and are often inserted into the space between the microvilli using a stalk-like cell appendage. In contrast, the predominant rod-shaped bacteria in the hindgut are tightly attached to the epithelium surface by an unusual pili-like structure. Both 16S rRNA gene denaturing gel gradient electrophoresis and metagenome library indicate that the CMC Mollicutes group 2 appears to be present in both the midgut and hindgut with no significant difference in abundance. The CMC Mollicutes group 1, however, was found mostly in the midgut of CMCs. The CMC gut Mollicutes phylotypes appear to be most closely related to Mollicutes symbionts detected in the gut of isopods (Crustacea: Isopoda. Overall, the results suggest that CMCs harbor diverse, novel and specific gut bacteria, which are likely to live in close relationships with the CMC host.

Researches are conducted into some processes of Japanese origin now enjoying high evaluation as global achievements are reviewed, which involve the separation and purification of butadiene, production of concentrated nitric acid, disproportionation of toluene, polymerization of vinyl chloride in a large reactor, development and practical application of lithium ion secondary batteries, and the enzymatic production of the D-amino acid. As examples of development of chemical technologies, furthermore, researches are undertaken into the ammonia synthesizing technology, production of resorcinol, and coal liquefaction. Also reviewed are data on the history of industries accommodated in museums, and numerous articles of scientific literature written in the period of Shogunate-end through Meiji-beginning to constitute the foundation on which Japan's scientific technologies would make rapid progress. The result gives suggestions for opening a new way toward creative and unique technologies. (NEDO)

    Through an arrangement of published data about American air lines during 1985 through 1987, the overall expense vs. transportation fee (expense vs. effect) was studied as a main viewpoint. As a result, the fuel oil cost, even in case of wide fuselage plane, high in transportation efficiency, was high in ratio, 32 to 52% (3 to 5 times as high as that 12 to 14 years ago), and fluctuated connectedly with the oil price. While the jet fuel price fluctuated connectedly with the oil price per equal volume with 1.3 to 1.4 of price ratio. Further, the flight range ratio was recorded to be approx. 0.06 to 0.24 km/kg. While the transportation efficiency was lower than approx. 5000kg*km/kg with a wide range of overall expense, approx. 9 to 87 cents per compensative transportation ton*km. Because even a sudden decrease in transportation quantity did not decrease the overall expense, it was known to be important in management to secure the transportation quantity. 30 refs., 15 figs., 1 tab.

The features include the relics of oxytone and barytone accentuation, columnal accentuation, the double-peaked and secondary stress types.The accentuation system of the Svirkos subdialect has been found to be rather close to other peripheral subdialects of the Vilnius dialect (Gervėčiai, Dieveniškės etc.. The parameters that help identify the closeness of the subdialects are as follows: 1 well-preserved barytone and oxytone accentuation patterns; 2 the impact of Slavic languages on prosody (violations of the Saussure-Fortunatov law, the stress placement is not related to the tone of the word, columnal accentuation. The author suggests that the double-peaked stress and the secondary phonological stress in northern dialects are stronger (in the area of the Utena dialect, whereas in southern dialects (southern highlanders weaker than in peripheral subdialects of the Vilnius dialect. Secondary non-phonological stresses, though optional, perform important functions: contribute to the rhythmic arrangement of the phrase (rhythmic stress, make up for the loss of ending or help preserve the full ending (morphemic stress. The accentuation systems of Vilnius dialect idioms are less different than their vocalisms.

    With an objective of saving energy and reducing greenhouse gas emission, a modernization project has been discussed on the North Bangkok heavy oil burning thermal power plant owned by Electricity Generating Authority of Thailand (EGAT). The present project plans to withdraw the existing units No. 1, 2 and 3, and install two new generating facilities with the rated output of 358.3 MW using natural gas as fuel. The present feasibility survey has performed detailed comparative discussions on four cases, whereas a proposal was selected to withdraw all of the boilers, steam turbines, and generators, and install two single axis combined cycle systems whose output has been increased by using the existing fuel tank area. The energy saving effect by this project can reduce fuel consumption annually by 514 kt of crude oil equivalent. The greenhouse gas can be reduced annually by 2,680 kt-CO2. The project will require a total fund of about 57 billion yen. The profitability assessment calls for the internal profitability of 8.413% and the investment fund efficiency of 1.69%. The economic investment payback effect of this project is determined sufficient. (NEDO)

  8. How Down is a Downbeat? Feeling Meter and Gravity in Music and Dance

    Full Text Available The idea that metrical accent might be related to an embodied sense of "up" and "down" is implied by the terms "upbeat" and "downbeat," and is central to theories of meter as gravitational field, such as those evolved by Robert Hatten and Steve Larson. Yet as Hatten himself notes, upbeats and downbeats do not always map conveniently on to upward or downward movements in dance. Drawing on ethnographic research among trainee ballet teachers and recent theories of musical meter, this article discusses some practical and theoretical problems that arise when trying to teach about meter in the context of ballet training. It is suggested that empathic listening and perspective taking, rather than appeals to common embodied experiences of meter, may be key to developing better interdisciplinary understanding between musicians and dancers.

    In a discharge excitation rare gas halide excima laser, uniform generation and stable maintenance of the excited discharge determines the laser characteristics. In this report, an approximate solution was obtained on the Boltzmann equation (frequently used for the theoretical analysis of this laser) to examine the nature of the solution. By optimizing the conversion of the variables, calculation of an electron swarm parameter in the hitherto uncertain range of the low conversion electric field was made possible, giving a generation mechanism of the uncertainty of the excited dischareg. The results are summarized as below. (1) The Boltzmann equation gives a linear solution for a logarithmic value of an electron energy in the range of low conversion electric field. (2) Time-wise responce ability between the measured voltage, current characteristics of the excitation discharge was clarified and the attachment and ionization coefficients calculated by Boltzmann equation. (3) Dependency of the attachment coefficient on the partial pressure of fluorine and kripton was examined, and the attachment coefficient was found to increase with the increase of the partial pressure for the both cases. 20 refs., 9 figs., 2 tabs.

    A feasibility study was conducted for the implementation of the optimum model project in the fiber dyeing and processing industry in Thailand. This paper describes the results of fiscal 1999. Seventy percent of about 400 companies are those heavily consuming energy, while small-scale businesses having a production capacity of less than one million yards/month take the sixty percent of the industry. Their energy conserving measures are behind. Measures against ground subsidence and drainage cost these companies greatly. Trade competition with China and others is being intensified. Although designated under the Energy Saving Promotion Act, the plants are not enjoying the privilege. Needed for the energy saving measures are grasp of the current situation such as energy consumption status, thorough operation management, improvement of energy efficiency in the present production facilities, renewal/additional installation of production equipment, and implementation of developmental energy saving measures. As energy conservation measures are deemed adaptable to the industry if the investment recovery period is two years or less, diagnostic analysis was made on six plants, with diffusion of the result examined. The total energy consumption of the industry was estimated to be reducible by 35% through high-recovery-rate measures such as improvement of boilers, recovery of exhaust heat, control of energy consumption rate, and introduction of dyeing machines having low liquor ratio.

    The industry of natural gas is finding great inter-relationship with the electric power section due to aspects technical, economical and institutional. In Brazil, this world tendency is increasing quickly, above all, starting from the crisis of energy lived by the Country in 2001. In spite of, in spite of being the third producing largest and consume-pain in Brazil, Bahia now is deficient in natural gas, committing the thermal-electricity generation due to lack of this energy one as well as, of the deficiency in the transport and distribution infrastructure. Besides, Bahia is the Brazilian state with the largest population without access the electric power. This motivates reflections concerning the potentialities of the natural gas to lessen this situation. Therefore, this work has an objective to evaluate the structures of the industry of the natural gas and the electric section in Bahia and the relationship among these segments. Initially, it tries to present the reasons that it is taking the development of the electric power generation in consonance with the industry of the gas.

    The paper surveyed the present situation and future trend of economy, energy supply/demand, coal production/distribution/utilization and the environmental effects in Thailand. The survey on the coal utilization and its environmental effects was partially requested of the environmental research institute in Thailand. The amount of coal utilization in Thailand rapidly increased to nearly four times as large as that ten years ago mainly in terms of domestic lignite under the government`s policy on expansion of the domestic energy use. However, most of this domestic lignite is low-grade coal with low calories and high sulfur content, and the use of it was rapidly increased mostly in power generation sector without no adequate environmental measures taken. This caused an environmental problem on air pollution due to sulfur oxides at Mae Moh power plant in the north several years ago, and the damages to the regional residents, etc. were given much publicity by journalism and developed the social problem. Accordingly, Thai people are now critical of the coal resource exploration and the coal use expansion. Under the circumstances, the Ministry of Industry and the energy related ministries/offices are obliged to review their development/promotion plans. 84 figs., 99 tabs.

    The paper investigated and studied the present situation and future trend of coal utilization and distribution in Thailand, and the present situation of environmental effects and the measures taken for environmental protection. Around 2010, coal will probably be produced only at EGAT`s Mae Moh (MM) coal mine. Demand for overseas coal is expected to be 40-50 million tons in 2011, and preparation of the coal center becomes a subject. For general industry use coal, pretreatment such as coal preparation, coal blending and briquetting is needed, considering coal quality, usage, transport distance and environmental effects. Brown coal of MM coal mine is a lignite with high sulfur, high ash content and low heating value. Wide spread of its use can be expected if upgrading is possible such as desulfurization, deashing, increasing heating value. In the electric power generation field, the absorber was installed at the existing boiler of the mine-mouth generating plant to conduct a verification test on high grade desulfurization of ultra-high sulfur lignite. In the industry field, the circulating fluidized bed boiler was adopted. In the residential/commercial field, introduction of briquette was proposed. 80 refs., 84 tabs.

    A demonstrative study was conducted in Thailand for grasping the effect on small electricity grids when several photovoltaic power generation systems, including AC modules, are connected to the grid. In fiscal 2000, surveys and studies were conducted about the data of the local power system, where to install the demonstrative system, and how to install the same, which were necessary for working out a basic design for Libong Island newly designated as the site for the demonstrative system. It was then concluded that the demonstrative system be a grid-connected 100 kW-level photovoltaic system comprising one main photovoltaic power station (85 kW), photovoltaic power systems for school buildings (3-6 kW, three schools), and AC modules (110 W, 10 locations). The manufacture of solar cell modules, grid-connected power conditioners, and measuring devices were completed. Civil engineering work and construction were under way on the site, including the construction of a management building, installation of concrete bases for solar cell arrays, construction of fences surrounding the site, and so forth.

    A potential study in FY 1998 was made of the energy/environment related activity implementation joint (COP3 related AIJ) in 6 Southeast Asian countries. Vietnam is a country which is the lowest in greenhouse effect gas (GHG) emission in the world, but they want the international assistance for their continued development and contribution to the global environment. Laos has to continue their economic development for extermination of poverty and improvement of life level. Accordingly, AIJ has to be the one that supports those and is helpful for both industrial development and environmental improvement. The same in Cambodia as in Laos, AIJ has to be the one that is helpful for both industrial development and promotion of environmental improvement. In Myanmar, GHG emits (CO2 conversion) 94.5% in the agricultural sector where methane is emitted from livestock and rice growing. There, the forest protection plays a big role. In Thailand, the use of land and forest protection are subjects mainly with the heightening of energy efficiency and fuel substitution. Malaysia, of course, promotes the economic development, has the leading GHG policy (traffic management in urban area, etc.), and wants the international technology transfer. (NEDO)

    Eine Säule der kausalen Therapie bei Patienten mit Ulcus cruris venosum ist die Kompressionstherapie. Sie unterstützt die Abheilung, reduziert Schmerzen und Rezidive und steigert die Lebensqualität. Bislang existieren kaum wissenschaftliche Daten zu dem Versorgungsstand und fachspezifischem Wissen von Patienten mit Ulcus cruris venosum. Standardisierte Fragebögen wurden bundesweit in 55 Pflegediensten, 32 Arztpraxen, vier Wundzentren und -sprechstunden sowie einem Pflegetherapiestützpunkt von Patienten mit Ulcus cruris venosum bei Erstvorstellung anonym ausgefüllt. Insgesamt nahmen 177 Patienten (Durchschnittsalter 69,4 Jahre; 75,1 % Frauen) teil. Ein florides Ulcus cruris venosum bestand im Mittel 17 Monate. 31,1 % hatten keine Kompressionstherapie, 40,1 % Binden und 28,8 % Strümpfe. Bei der Bestrumpfung hatten 13,7 % Kompressionsklasse III, 64,7 % Kompressionsklasse II und 19,6 % Kompressionsklasse I. 70,6 % legten die Strümpfe nach dem Aufstehen an, 21,1 % trugen sie Tag und Nacht. 39,2 % bereiteten die Strümpfe Beschwerden. Lediglich 11,7 % hatten eine An- und Ausziehhilfe. Die Binden wurden im Mittel 40,7 Wochen getragen und bei 69 % nicht unterpolstert. Bei 2,8 % wurde der Knöchel- und Waden-Umfang zur Erfolgskontrolle gemessen. Venensport machten 45,9 %. Ein Drittel hatte keine Kompressionsversorgung, obwohl diese eine Basismaßnahme der Therapie des Ulcus cruris venosum ist. Zudem ist deren korrekte Auswahl und Anwendung angesichts der langen Bestandsdauer der Ulzerationen zu hinterfragen. Weiterführende Fachkenntnisse bei Anwendern und Verordnern sowie Patientenschulungen sind erforderlich. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Taiwan, hence, embarked on a decade of integrating biodiversity data. Under the support of NSC and COA, the database and websites of TaiBIF, TaiBNET (TaiCOL, TaiBOL, and TaiEOL have been established separately and collaborate with the GBIF, COL, BOL, and EOL respectively. A cross-agency committee was thus established in Academia Sinica in 2008 to formulate policies on data collection and integration as well as the mechanism to make data available to the public. Any commissioned project will hereafter be asked to include these policy requirements in its contract.

    This study aimed to determine whether reproductive performance of ewes submitted to laparoscopic timed artificial insemination (TAI) would be similar to ante meridiem (AM)/post meridiem (PM) rule and assisted natural mating (NM), and whether GnRH may enhance the pregnancy rate in TAI. In experiment I, 191 non-lactating ewes were synchronized, then TAI was performed either 48 h after progesterone (P4) removal (TAI-48 h) or 12 h after estrus detection (AM/PM); moreover, some ewes were submitted to NM (NM) as control treatment. In experiment II, 247 non-lactating ewes were allocated in five treatments, a control (no-GnRH on protocol) and four treatments arranged in a factorial design 2 × 2. The factors were time and dose of GnRH: ewes that received either 10 μg (TAI-10 μg-36 h) or 25 μg of GnRH (TAI-25 μg-36 h) 36 h after P4 removal and ewes that received either 10 μg (TAI-10 μg-48 h) or 25 μg of GnRH (TAI-25 μg-48 h) at time of insemination, 48 h after P4 removal. In experiment I, pregnancy rate in TAI-48 h was lower (P = 0.03) than AM/PM and NM. Moreover, the probability of pregnancy in TAI-48 h was higher (P = 0.06) in ewes detected in estrus early. In experiment II, the use of GnRH in TAI protocols increased (P < 0.01) pregnancy rate at synchronization, and TAI-25 μ-48 h and TAI-10 μg-36 h treatments increased (P = 0.02) pregnancy rate compered to TAI-10 μg-48 h. We conclude that TAI decreased pregnancy rate compered to NM and AM/PM, which may be improved by GnRH use in TAI to synchronize ovulation.

    Thyroid autoimmunity (TAI) is frequent in infertile women, but to what extent thyroglobulin autoantibodies (Tg-Abs) contribute to TAI is unclear in the literature. The aims of the present study were to determine the prevalence of TAI in women consulting for fertility problems and to investigate the impact of isolated Tg-Abs, isolated thyroid peroxidase autoantibodies (TPO-Abs), and the presence of both autoantibody types on thyroid function. Furthermore, thyroid function was compared between women with and without TAI and between infertile and fertile women. A cross-sectional data analysis nested within an ongoing prospective cohort study was performed in order to determine the prevalence of TAI in unselected women consulting our tertiary referral center for reproductive medicine (CRM). The women underwent a determination of serum thyrotropin (TSH), free thyroxine (FT4), TPO-Abs, and Tg-Abs. The cause of infertility, age, body-mass index (BMI), and smoking habits were recorded. The prevalence of TAI was 16% (163/992). In 8% of cases, both types of autoantibodies were present, in 5% isolated positive Tg-Abs were found, and 4% had isolated positive TPO-Abs (p=0.025 and p=0.003 respectively). The prevalence of TAI was significantly higher in infertile women as compared to that in fertile controls (19% vs. 13%; p=0.047). The median serum TSH level was significantly higher in the women with TAI and with isolated positive Tg-Abs compared to that in women without TAI (1.83 [1.44] and 1.90 [0.85] vs. 1.47 [0.94] mIU/L; phabits were comparable between the study groups. The prevalence of TAI was higher in infertile women as compared to fertile women consulting our CRM. Five percent of the women had isolated positive Tg-Abs and a significantly higher serum TSH compared to that in women without TAI.

In den ersten 6 Monaten wurden 404 Patienten erfasst. Nur 15 % hatten zum Zeitpunkt der Fraktur eine osteoprotektive Therapie, obwohl 52 % bereits zumindest eine prävalente osteoporotische Fraktur aufwiesen. Lediglich 59 Patienten (15 % hatten einen normalen 25- Hydroxyvitamin-D-Serumspiegel von 30 ng/mL, wobei 37 Patienten (62 % davon vorsubstituiert waren. Diese ersten Auswertungen zeigen die eklatante Unterversorgung in diesem Patientenkollektiv, welche in Kombination mit der pandemisch vorliegenden Vitamin-D-Defizienz die hohe Dringlichkeit eines interdisziplinären Managements über die chirurgische Versorgung hinaus unterstreicht.

  4. Die Entdeckung des Higgs-Teilchens oder wie das Universum seine Masse bekam

    2013-01-01

    Im Oktober 2013 setzte der Nobelpreis für Peter Higgs und François Englert den vorläufigen Höhepunkt in der verrückten Geschichte um das sogenannte Gottesteilchen, das Higgs-Boson. Schon im Juli des Vorjahres hatten die Physiker weltweit gejubelt: Mehr als fünfzig Jahre nachdem Peter Higgs und andere Wissenschaftler die Existenz des Teilchens theoretisch begründet hatten, war es im gigantischen Teilchenbeschleuniger CERN gefunden worden. Jetzt erzählen Harald Lesch und seine Co-Autoren, warum sich rund um das Higgs-Teilchen so viele skurrile Missverständnisse und mediale Sensationen ranken. Gewohnt kurzweilig und gut verständlich enthüllen sie, wie aus dem verzweifelt gesuchten „gottverdammten Teilchen“ das Gottesteilchen wurde, dass der Urknall nicht simuliert werden kann und dass Schwarze Löcher nicht unbedingt alles verschlingende Monster sind. Dabei wird deutlich, dass die Suche nach den geheimnisvollen Kräften, die das Universum, unsere Erde und letztlich auch uns Menschen zusammenhalten...

    In order to provide discussion materials for measures to achieve the GHG emission reduction target, investigations and discussions have been made on the following subjects: cost effectiveness of reducing GHG emission by target countries and target technologies, use of maps and databases on the possible reduction quantity of GHG emission, the targeted countries and business categories. Regarding the target countries, investigations were made on the general situation of the energy consumption efficiency, difference between their energy consumption efficiency by industries and that in Japan, and the GHG emission quantities by sectors. As a result, 31 counties hopeful in reducing CO2 emission were selected. With regard to technologies to reduce CO2 emission, technologies having been practically used and proliferated in Japan were used as the base, whereas 43 technologies were systematized for such departments as industries, business operations, households, and transportation. According to a trial calculation on the effect of CO2 emission reduction, if the 43 technologies are applied to the 31 target countries, CO2 emission reduction of 698 million tons as a whole would be possible, for which the required expense was calculated as 114.4 trillion yen. In evaluating the CO2 emission reducing technologies, the cost effectiveness of each technology was evaluated by cost per GHG emission reduction of 1t-CO2. (NEDO)

    The present investigative research is intended to grasp the whole image of cost effectiveness of the energy saving and new energy technologies to suppress and reduce CO2 emission in Japan. Furthermore, the research considers the cost effectiveness and discusses the efficiency and the directionality of reducing CO2 emission from an estimation of the social introduction cost of individual technologies and quantity of CO2 emission reduction. These activities are intended to provide the fundamental items of information when discussing the measures to achieve the emission reduction target imposed on Japan. The research divides the whole aspect into energy conversion, industrial, consumer and transportation departments for discussion, and calculates the technological items that can be introduced by 2010 and the quantity of the introduction thereof, as well as the effect of reducing CO2 emission. Calculations are also performed on 27 elementary technologies in total and the CO2 emission reducing effect, assuming technological possibilities. Subsequently, analyses are carried out from the viewpoint of cost effectiveness by departments. It is shown that the average cost effectiveness is distributed in the range from 108,000 yen/ton to 1,129,000 yen/ton. Scenarios of reducing CO2 emission are discussed from the analyses of the cost effectiveness. (NEDO)

    This paper introduces activities performed by Chubu Electric Power Co., Inc. on ice heat storage air conditioning systems. Chubu Electric Power has worked with concerted efforts particularly on proliferation of an ice heat storage type air conditioning system, called `Eco-Ice`. A `heat storage air conditioner group` has been established in the sales department of the head office, and `market development groups` in branch offices to advance the recommendation activities. The Eco-Ice has been publicized on TV commercials, and the `97 Electric Power Heat Storage Air Conditioning Fair was held. Individual discrete type models were added to the product line-up in fiscal 1995. In addition, because of the system economy having been improved as a result of the improvements in the governmental subsidy system, power charge system, and support system, the number of Eco-Ice contracts is increasing rapidly. Two-hundred and forty Eco-Ice systems were contracted from April to October 1997, which means that peak shift capacity reached 7887 kW. Compared with the same period of fiscal 1996, the number of contract increased by 74 cases or 45% , and the peak shift capacity increased by 3148 kW or 66%. 4 figs.

  11. A role for Taiman in insect metamorphosis.

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Recent studies in vitro have reported that the Methoprene-tolerant (Met and Taiman (Tai complex is the functional receptor of juvenile hormone (JH. Experiments in vivo of Met depletion have confirmed this factor's role in JH signal transduction, however, there is no equivalent data regarding Tai because its depletion in larval or nymphal stages of the beetle Tribolium castaneum and the bug Pyrrhocoris apterus results in 100% mortality. We have discovered that the cockroach Blattella germanica possesses four Tai isoforms resulting from the combination of two indels in the C-terminal region of the sequence. The presence of one equivalent indel-1 in Tai sequences in T. castaneum and other species suggests that Tai isoforms may be common in insects. Concomitant depletion of all four Tai isoforms in B. germanica resulted in 100% mortality, but when only the insertion 1 (IN-1 isoforms were depleted, mortality was significantly reduced and about half of the specimens experienced precocious adult development. This shows that Tai isoforms containing IN-1 are involved in transducing the JH signal that represses metamorphosis. Reporter assays indicated that both T. castaneum Tai isoforms, one that contains the IN-1 and another that does not (DEL-1 activated a JH response element (kJHRE in Krüppel homolog 1 in conjunction with Met and JH. The results indicate that Tai is involved in the molecular mechanisms that repress metamorphosis, at least in B. germanica, and highlight the importance of distinguishing Tai isoforms when studying the functions of this transcription factor in development and other processes.

  12. A Review of Traumatic Axonal Injury following Whiplash Injury As Demonstrated by Diffusion Tensor Tractography

    Sung Ho Jang

    2018-02-01

    Full Text Available Whiplash is a bony or soft tissue injury resulting from an acceleration–deceleration energy transfer in the neck. Although patients with whiplash injury often complain of cerebral symptoms, and previous studies have reported evidence indicating brain injury, such an association has not been clearly elucidated. Traumatic axonal injury (TAI is tearing of axons due to indirect shearing forces during acceleration, deceleration, and rotation of the brain or to direct head trauma. Diffusion tensor imaging (DTI has a unique advantage to detect TAI in patients whose conventional brain CT or magnetic resonance imaging (MRI results were negative following head trauma. Since the introduction of DTI, six studies using diffusion tensor tractography (DTT based on DTI data have reported TAI in patients with whiplash injury, even though conventional brain CT or MRI results were negative. A precise TAI diagnosis in whiplash patients is clinically important for proper management and prognosis. Among the methods employed to diagnose TAI in the six previous studies, the common diagnostic approach for neural tract TAI in individual patients with whiplash injury were (1 whiplash injury history due to car accident; (2 development of new clinical symptoms and signs after whiplash injury; (3 evidence of neural tract TAI in DTT results, mainly via configurational analysis; and (4 coincidence of newly developed clinical manifestations and the function of injured neural tracts. All six studies were individual patient case studies; therefore, further prospective studies involving larger number of subjects should be encouraged.

  13. Differences in the acute intestinal syndrome after partial and total abdominal irradiation in mice

    International Nuclear Information System (INIS)

    Dewit, L.; Oussoren, Y.; Bartelink, H.; Stewart, F.A.

    1985-01-01

    The acute intestinal syndrome in mice was analysed after partial (PAI) and total abdominal irradiation (TAI). The LDsub(50/15) was significantly higher after PAI (16.3 Gy) than after TAI(14.3 Gy). The dose-response curve for maximal weight loss also showed a shift of 1.8-2 Gy to higher doses after PAI compared with TAI. The X-ray survival curve for duodenal crypt cells was shifted by only 0.6 Gy for PAI and TAI. In order to assess the possible role of radiation-induced leucopenia and the influence of irradiating the spleen (shielded with PAI), lethality, weight loss and blood leucocyte counts were compared after PAI and TAI in splenectomized and non-splenectomized mice. No major difference in leucopenia was found between the different treatment groups, whereas the differences in lethality and weight loss between PAI and TAI remained the same. Shielding the spleen in the partial abdominal field therefore did not contribute to the difference in LDsub(50/15). These findings imply that the increased LDsub(50/15) after PAI compared with TAI was mainly due to shielding of a small part of the bowel (about 13 per cent of the abdominal area). (author)

    Several studies have suggested that the association between aspirin and improved cancer survival is mediated through the mechanism of aspirin as thrombocyte aggregation inhibitors (TAI). The aim of this study was to provide epidemiological evidence for this mechanism assessing the association between overall survival and the use of aspirin and non-aspirin TAI in patients with colorectal cancer. In this observational study, data from the Netherlands Comprehensive Cancer Organisation were linked to PHARMO Database Network. Patients using aspirin or aspirin in combination with non-aspirin TAI (dual users) were selected and compared with non-users. The association between overall survival and the use of (non-)aspirin TAI was analysed using Cox regression models with the use of (non-)aspirin TAI as a time-varying covariate. In total, 9196 patients were identified with colorectal cancer and 1766 patients used TAI after diagnosis. Non-aspirin TAI were mostly clopidogrel and dipyridamole. Aspirin use was associated with a significant increased overall survival and hazard ratio (HR) 0.41 (95% confidence interval [CI] 0.37-0.47), and the use of non-aspirin TAI was not associated with survival of HR 0.92 (95% CI 0.70-1.22). Dual users did not have an improved overall survival when compared with patients using solely aspirin. Aspirin use after diagnosis of colorectal cancer was associated with significantly lower mortality rates and this effect remained significant after adjusting for potential confounders. No additional survival benefit was observed in patients using both aspirin and another TAI. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Visualisierungen von Wissen hatten und haben im Kern des Faches Soziologie einen schweren Stand. Gerald BECK nimmt sich daher in seinem Buch "Sichtbare Soziologie" der Thematik an, um die Stellung von Visualisierungen in der Soziologie zu verstehen, damit verbundene Problemfelder zu identifizieren und für visuelle Umsetzungen zu sensibilisieren. Er setzt dazu beim Übergang zur Zweiten Moderne an und betrachtet anhand von neun Fallbeispielen gelungene und weniger gelungene Visualisierungen. Durch die verkürzte Aufarbeitung des Verhältnisses der Soziologie zum Bild bleiben jedoch wichtige Einsichten unberücksichtigt, sodass BECKs Empfehlungen, die Zahl der Visualisierungen und die visuelle Kompetenz zu erhöhen, kaum geeignet sind, die Skepsis in der Soziologie gegenüber Visualisierungen zu überwinden.

    Die gravierenden Veränderungen des Marktes und des Wettbewerbes infolge der Globalisierung Ende des 20. Jahrhunderts hatten auch einschneidende Auswirkungen auf die industrielle Instandhaltung. Dies galt sowohl für die unternehmensinterne Instandhaltung als auch für die externen Instandhaltungsdienstleister. Die Instandhaltung, die sich in der Vergangenheit schon ständig den sich verändernden wirtschaftlichen Rahmenbedingungen in der Regel auch erfolgreich angepasst hatte, stand vor einer neuen Herausforderung. Sie wurde erneut hinsichtlich ihrer Schnittstellen, Arbeitsteilung und Organisation sowie der Flexibilität, Qualität, Nachhaltigkeit und Gesamteffizienz in vielen Unternehmen sowohl intern als auch extern zunehmend sehr kritisch betrachtet. Es wurde in vielen Unternehmen prinzipiell alles auf den Prüfstand gestellt und bisherige Strukturen, Abläufe, Strategien und Prozesse hinsichtlich des vorhandenen Verbesserungspotenzials hinterfragt. Dabei wurde auch sehr oft über den "eigenen Tellerrand“ geschaut und externer Sachverstand genutzt.

  10. Changes in the Severity and Injury Sources of Thoracic Aorta Injuries due to Vehicular Crashes.

    Science.gov (United States)

    Ryb, Gabriel; Dischinger, Patricia; Kerns, Timothy; Burch, Cynthia; Rabin, Joseph; Ho, Shiu

    Research using the National Automotive Sampling System-Crashworthiness Data System (NASS-CDS) suggested a decreased adjusted risk of thoracic aorta injuries (TAI) for newer vehicles during near-side crashes and an increased adjusted TAI risk during frontal crashes. This study attempted to explore possible explanations of these findings. Adult front seat occupants in the Crash Injury Research and Engineering Network (CIREN) database through June 2012 were studied. TAI cases were compared with remaining cases in relation to crash and vehicular characteristics. TAI cases of later crash year (CY) (2004-2012) were compared to those in earlier CY (1996-2003) in relation to TAI severity (minor, moderate, severe and non-survivable). TAI cases in newer model year (MY) vehicles (1999-2012) were compared to those in older vehicles (1988-98) in relation to injury source (steering wheel, front, left, seat belt, air bag and other or unknown). Analysis was stratified by direction of impact (frontal and near-side) and the use of restraints. The similar TAI severity of earlier and later CY among frontal crashes suggests that the observed changes in the adjusted odds of injury seen in NASS-CDS are not due to an increase in injury detection. The decrease in TAI severity among newer vehicles in near-side crashes of later CY is consistent with a beneficial effect of crashworthiness improvements for this crash configuration. A shift of injury source in frontal crashes from the steering wheel in older vehicles to "front of vehicle structures", "seat belts" and "unknown and other" in newer vehicles should suggest potential sites for crashworthiness improvements.

    Research highlights: → The TAI inhibitor showed peak-value-phenomenon due to the change of adsorption mode. → The adsorption of TAI inhibitor made the PZC shift toward positive direction. → The adsorption film occurred by forming coordination bonds between heteroatom and Fe. → Bigger adhesive force owing to hydrophobic interaction was detected in TAI solution. → The long range-repulsive force reduced by screening effect of surface charges of TAI. - Abstract: The inhibition performance of a newly synthesized thioureido imidazoline inhibitor (TAI) in CO 2 corrosion was studied by using electrochemical impedance spectroscopy (EIS), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). Results show that the values of inhibition efficiency show peak-value-phenomenon at concentration of 0.15 mmol dm -3 owing to the change of adsorption mode. The adsorption of protonated TAI molecules on the negatively charged steel surface makes the potential of zero charge (PZC) shift to positive direction, and the long-range electrostatic exclusive forces between AFM tip and sample surface are reduced by screening effect of surface charges.

    Full Text Available Trauma patients with thoracic aortic injury (TAI suffer blunt cardiac injury (BCI at variable frequencies. This investigation aimed to determine the frequency of BCI in trauma patients with TAI and compare with those without TAI. All trauma patients with TAI who had admission electrocardiography (ECG and serum creatine kinase-MB (CK-MB from January 1999 to May 2009 were included as a study group at a level I trauma center. BCI was diagnosed if there was a positive ECG with either an elevated CK-MB or abnormal echocardiography. There were 26 patients (19 men, mean age 45.1 years, mean ISS 34.4 in the study group; 20 had evidence of BCI. Of 52 patients in the control group (38 men, mean age 46.9 years, mean ISS 38.7, eighteen had evidence of BCI. There was a significantly higher rate of BCI in trauma patients with TAI versus those without TAI (77% versus 35%, P<0.001.

    Objective : We assessed the level of students' test anxiety, and the relationship between test anxiety and academic performance. Methods : We recruited 166 third-quarter students. The Test Anxiety Inventory (TAI) was administered to all participants. Total scores from written examinations and objective structured clinical examinations (OSCEs) were used as response variables. Results : Multiple regression analysis shows that there was a modest, but statistically significant negative correlation between TAI scores and written exam scores, but not OSCE scores. Worry and emotionality were the best predictive models for written exam scores. Mean total anxiety and emotionality scores for females were significantly higher than those for males, but not worry scores. Conclusion : Moderate-to-high test anxiety was observed in 85% of the chiropractic students examined. However, total test anxiety, as measured by the TAI score, was a very weak predictive model for written exam performance. Multiple regression analysis demonstrated that replacing total anxiety (TAI) with worry and emotionality (TAI subscales) produces a much more effective predictive model of written exam performance. Sex, age, highest current academic degree, and ethnicity contributed little additional predictive power in either regression model. Moreover, TAI scores were not found to be statistically significant predictors of physical exam skill performance, as measured by OSCEs.

    The objective was to determine whether the presence of fertility-associated antigen (FAA) on sperm collected from Nelore (Bos indicus) bulls can be used to assess potential fertility of sperm for use at first-service fixed-time AI (TAI). Six Nelore bulls were selected based on FAA status (FAA-negative: N = 3; FAA-positive: N = 3) and the ability to produce neat semen with ≥ 70% morphologically normal sperm and 60% estimated progressive motility before cryopreservation. In Experiment 1, suckled multiparous Nelore cows (N = 835) were evaluated for body condition score (BCS) and received an intravaginal progesterone device (CIDR) and 2.0 mg of estradiol benzoate (Day 0). On Day 9 the CIDR was removed, 12.5 mg of PGF(2α) and 0.5 mg of estradiol cypionate were administered, and calves were removed for 48 h. All cows received TAI on Day 11 (48 h after CIDR removal). Pregnancy per TAI (P/TAI) was not different between FAA-positive and FAA-negative bulls (41.5% vs. 39.3%, respectively). There was an effect of AI technician on P/TAI (36.0% vs. 43.9%; P cows with BCS ≥ 2.75 were 1.4 times more likely to become pregnant compared with cows with BCS fertility of sperm for use in TAI.

    Full Text Available Efficacy of the β-adrenergic receptor blocker (carazolol at Timed Artificial Insemination (TAI was investigated. Cows (n = 73 were pre-synchronized with two PGF2α injections given 14 d apart to initiate the Ovsynch protocol at early and middle luteal stages 14 d later, and received injections of GnRH and PGF2α seven d apart followed by GnRH 48 h later, and TAI 16 - 18 h later. Corpus luteum (CL was detected via rectal palpation at the beginning of the Ovsynch protocol. Carazolol (Treatment I; n = 41 or physiologic saline (Treatment II; n = 32 were administered via jugular vein five min before TAI. Uterine tone was determined prior to infusion and at TAI via rectal palpation. Pregnancies were diagnosed with transrectal ultrasonography 40 ± 7 d after TAI. Uterine tone was 2.8 (1.4 - 5.3 times higher (P P < 0.05, and 66.7%, 75%, 52.6%, 100% and 16.7%, 33.3%, 25%, 28.6% in primiparous cows with CL and without CL, and in multiparous cows with CL and without CL in Treatments I and II, respectively. Pregnancy rates did not differ between treatments I (34.2% and II (40.6%. In conclusion, no beneficial effect of carazolol administration prior to TAI was found except for the increased uterine tone.

    Achilles tendon is the tendon connecting the heel with the calf muscles. Tendo-achilles injury (TAI) in players is common in games. The frequency of TAI is unknown and aetiology is controversial: The present descriptive cross-sectional study was done to determine the prevalence of TAI and associated factors contributing to it in football, cricket and badminton. From January to June 2012, male players (n = 131), age -17-35 years, were selected by purposive sampling technique from renowned sporting clubs at Dhaka, Bangladesh. TAI was diagnosed through structured questionnaire and interviewing the respondents. The analysis by Statistical Package for Social Sciences (SPSS) programme revealed that 11.5% players suffered from TAI, i.e. prevalence was 115 per 1000 respondents. Most injuries (70/131; 53.4%) occurred in the playground and (59/131; 45.3%) happened in practice field. Injuries among the players of third division were higher, i.e. about 36% (p = 0.000). TAI was significantly dependent on occupation (p = 0.046), BMI (p = 0.008), divisional status (p = 0.023), game type (p = 0.043), ground condition (p = 0.05) and injury severity (p = 0.000). The injured players referred for treatment to the physiotherapist was highest (9/15, i.e. 60%) followed by the physicians (5/15, i.e. 33%) (p = 0.000). The associations of TAI with various factors were discussed suggesting effective measures be taken and treatment, particularly physiotherapy, be given to injured players. However, there is a need of team work with sports medicine specialist also to enable the injured players to continue their professional games.

    Homology-based gene/gene-analog cloning method has been extensively applied in isolation of RGAs (resistance gene analogs) in various plant species. However, serious interference of sequences on homoeologous chromosomes in polyploidy species usually occurred when cloning RGAs in a specific chromosome. In this research, the techniques of chromosome microdissection combined with homology-based cloning were used to clone RGAs from a specific chromosome of Wheat-Thinopyrum alien addition line TAi-27, which was derived from common wheat and Thinopyrum intermedium with a pair of chromosomes from Th. intermedium. The alien chromosomes carry genes for resistance to BYDV. The alien chromosome in TAi-27 was isolated by a glass needle and digested with proteinase K. The DNA of the alien chromosome was amplified by two rounds of Sau3A linker adaptor-mediated PCR. RGAs were amplified by PCR with the degenerated primers designed based on conserved domains of published resistance genes (R genes) by using the alien chromosome DNA, genomic DNA and cDNA of Th. intermedium, TAi-27 and 3B-2 (a parent of TAi-27) as templates. A total of seven RGAs were obtained and sequenced. Of which, a constitutively expressed single-copy NBS-LRR type RGA ACR 3 was amplified from the dissected alien chromosome of TAi-27, TcDR 2 and TcDR 3 were from cDNA of Th. intermedium, AcDR 3 was from cDNA of TAi-27, FcDR 2 was from cDNA of 3B-2, AR 2 was from genomic DNA of TAi-27 and TR 2 was from genomic DNA of Th. intermedium. Sequence homology analyses showed that the above RGAs were highly homologous with known resistance genes or resistance gene analogs and belonged to NBS-LRR type of R genes. ACR 3 was recovered by PCR from genomic DNA and cDNA of Th. intermedium and TAi-27, but not from 3B-2. Southern hybridization using the digested genomic DNA of Th. intermedium, TAi-27 and 3B-2 as the template and ACR 3 as the probe showed that there is only one copy of ACR 3 in the genome of Th. intermedium and TAi

    Recently, reproductive management has become more difficult as a result of increased herd size. Problems with missing estrous signs and decrease in conception rate by artificial insemination (AI) performed at wrong timing have caused low AI conception rates. In 1995, ovulation synchronization and fixed-time AI (Ovsynch/TAI) was developed in the USA as a new reproductive technology, which was accepted as an useful reproductive management tool in many countries. However, no information on the use of Ovsynch/TAI was available in Japan. It was, therefore, warranted to show the ovulation rate and conception rate after Ovsynch/TAI using gonadotropin releasing hormone analogue (GnRH-A, fertirelin acetate) and prostaglandin F2alpha (PGF2alpha)-THAM, both were commercially available in this country. The conception rate after Ovsynch/TAI has been known to vary among different herds and individuals. Investigation and analysis of factors affecting the conception rate was also warranted to improve the conception rate. A series of experiments were carried out to establish Ovsynch/TAI using domestically produced GnRH-A and PGF2alpha and to study factors affecting conception rate after Ovsynch protocol. Ovsynch using 100 microg GnRH-A and 25 mg PGF2alpha were observed using ultrasonography. As a result, a high synchronization rate of ovulation at 16 to 20 h after the second GnRH injection was confirmed. The conception rate after Ovsynch/TAI was compared in 87 cows with the conception rate after AI at estrus induced by PGF2alpha (139 cows). Conception rate after Ovsynch/TAI was higher than the figure after AI at induced estrus (59.1% vs 20.9%, Pbody condition score (BCS) was 3.75 at dry period and 3.0 at the day of Ovsynch. In conclusion, Ovsynch/TAI is an effective tool for the reproductive management of dairy cows. A steady and sufficient conception rate after Ovsynch/TAI could be expected by taking the factors affecting the conception rate into the consideration.
