Why the abnormal phenomena of D-band center theory exist?A new BASED theory for surface catalysis and chemistry

Since the D-band center theory was proposed,it has been widely used in the fields of surface chemistry by almost all researchers,due to its easy understanding,convenient operation and relative accuracy.However,with the continuous development of material systems and modification strategies,researchers have gradually found that D-band center theory is usually effective for large metal particle systems,but for small metal particle systems or semiconductors,such as single atom systems,the opposite conclusion to the D-band center theory is often obtained.To solve the issue above,here we propose a bonding and anti-bonding orbitals stable electron intensity difference(BASED)theory for surface chemistry.The newly-proposed BASED theory can not only successfully explain the abnormal phenomena of D-band center theory,but also exhibits a higher accuracy for prediction of adsorption energy and bond length of intermediates on active sites.Importantly,a new phenomenon of the spin transition state in the adsorption process is observed based on the BASED theory,where the active center atom usually yields an unstable high spin transition state to enhance its adsorption capability in the adsorption process of intermediates when their distance is about 2.5Å.In short,the BASED theory can be considered as a general principle to understand catalytic mechanism of intermediates on surfaces.

Effects of nutritional and psychological status in gastrointestinal cancer patients on tolerance of treatment

AIM: To assess the effects of poor nutritional and psychological status on tolerance of cancer treatment and the recovery of physical performance status in patients with gastrointestinal cancer. METHODS: An epidemiological survey with respect to nutritional and psychological status in patients with gastrointestinal cancer was conducted among 182 operated patients in four provincial-level hospitals from December 2005 to June 2006. The food frequency survey method, state-trait anxiety inventory (STAI) and depression status inventory (DSI) were used to obtain information about the diet and psychological status in the patients. Nutritional status in the participants was reflected by serum albumin (Alb), hemoglobin (HB) and body mass index (BMI). RESULTS: Alb, protein intake and anxiety were associated with the severity of side effects of treatment. The adjusted relative risk (RR) for Alb, protein intake and anxiety was 3.30 (95% CI: 1.08, 10.10, P = 0.03), 3.25 (95% CI: 1.06, 9.90, P = 0.04) and 1.48 (95% CI: 1.29, 1.70, P < 0.0001), respectively. Moreover, calorie intake, HB and depression were associated with the recovery of physical performance status in the patients. Adjusted relative risk was 2.12 (95% CI: 1.09, 4.03, P = 0.028), 2.05 (95% CI: 1.08, 3.88, P =0.026) and 1.07 (95% CI: 1.02, 1.12, P = 0.007), respectively. CONCLUSION: Both poor nutrition status and psychological status are independent risk factors for severe side effects of cancer treatment, and have impact on the recovery of physical performance status in patients after treatment.

Functional dyspepsia:Are psychosocial factors of relevance?

The pathogenesis of Functional Dyspepsia （FD） remains unclear, appears diverse and is thus inadequately understood. Akin to other functional gastrointestinal disorders, research has demonstrated an association between this common diagnosis and psychosocial factors and psychiatric morbidity. Conceptualising the relevance of these factors within the syndrome of FD requires application of the biopsychosocial model of disease. Using this paradigm, dysregulation of the reciprocal communication between the brain and the gut is central to symptom generation, interpretation and exacerbation. Appreciation and understanding of the neurobiological correlates of various psychological states is also relevant. The view that psychosocial factors exert their influence in FD predominantly through motivation of health care seeking also persists. This appears too one-dimensional an assertion in light of the evidence available supporting a more intdnsic aetiological link. Evolving understanding of pathogenic mechanisms and the heterogeneous nature of the syndrome will facilitate effective management. Co-morbid psychiatric illness warrants treatment with conventional therapies. Acknowledging the relevance of psychosocial variables in FD, the degree of which is subject to vadation, has implications for assessment and management. Available evidence suggests psychological therapies may benefit FD patients particularly those with chronic symptoms. The rationale for use of psychotropic medications in FD is apparent but the evidence base to support the use of antidepressant pharmacotherapy is to date limited.

ENDOMYOCARDIAL FIBROSIS IN CHINA

To introduce the epidemical, pathological, and clinical characteristics as well as the diagnostic and therapeutical experiences of endomyocardial fibrosis(EMF) in China. [WT5”BX] Data sources.[WT5”BZ]A CMBdisc search was done of the Chinese language literature published from January 1983 through June 1997 about EMF and/or restrictive cardiomyopathy. A manual search was then done for other contributions, including abstracts, between January 1965 and June 1997. [WT5”BX] Results. [WT5”BZ]Eighty seven Chinese cases of EMF were collected in this paper. There were 49 men and 38 women, with a mean age of 28±13 years(range, 8 to 68 years). The distribution of the cases is mainly in the south of China. Combined right and left ventricular disease occurs in 48 percent of cases, with pure right ventricular involvement occurring in 42 percent and pure left ventricular involvement in the remaining 10 percent of patients who are examined postmortem. The diagnosis of EMF was confirmed in 21 cases at autopsy, and in 66 cases by echocardiography, angiocardiography, and/or endomyocardial biopsy which showed the characteristic changes. Clinically, right sided disease is the commonest variety. Endocardiectomy and tricuspid(n=7) or mitral(n=1) valves replacement have been performed in 8 patients. There were 2 operative deaths. Six patients had a satisfactory recovery postoperatively and living well in the follow up duration. [WT5”BX] Conclusion.

Effects of Matrine on Aconitine-Induced Electrophysiological Changes in Rat Ventricular Myocytes

Aim To explore the reason that the antiarrhythmic effect of the extract oftraditional Chinese medicinal herb, matrine, is weaker than quinidine and verapamil by comparison ofthe effect and efficacy of matrine on various kinds of transmembrane ionic currents with those ofquinidine and verapamil; and to demonstrate the best targets for antiarrhythmic drugs. MethodsWhole-cell patch-clamp techniques were used to record the action potential and ionic currents insingle cells of rat ventricular myocytes. Aconitine was used to induce the changes of ioniccurrents, then study the effects of matrine and quinidine, verapamil on aconitine-induced unbalancedchannel currents and action potential. Results Aconitine 1 μmol·L^(-1) induced significantchanges in transmembrane currents and action potential in single cells of rat ventricular myocytes.APD was significantly prolonged by aconitine. Simultaneously, aconitine increased sodium, L-typecalcium and inward rectifier potassium currents. Matrine 100 μmol· L^(-1) reversed theaconitine-induced changes of sodium current (I_(Na)) from (-70.2+- 10.5) pA/pF to ( - 39.6+-4.0)pA/pF(n = 5, P < 0.05 vs aconitine); L-type calcium current (I_(Ca-L)) from (20.4+- 3.8) pA/pF to (- 12.9+- 2.9) pA/pF ( n = 6, P < 0.01); the inward rectifier potassium current (I_(k1) ) from (-32.2+- 1.08) pA/pF to ( -24.0+-3.4) pA/pF (n = 6, P < 0.01), and action potential duration. Thereversal effects of quinidine and verapamil on aconitine-induced changes of APD and ionic currentswere more marked than matrine. Conclusion Aco-nitine significantly disturbs the normal equilibriumof ion channels in ventricular myocytes. It induces changes of I_(Na), I_(Ca-L), I_(K1) andprolongation of action potential duration. Matrine at concentration 50 or 100 μmol·L^(-1)statistically significantly suppresses aconitine-induced changes of APD and ionic currents. Thepotency and efficacy of inhibitory effect of matrine are markedly weaker than those of commonly usedverapamil and quinidine.

The Relevance of Vygotsky＇s Developmental Perspective to the Debate on Methodology in Psychological Science

Throughout his work, Lev S. Vygotsky （1896-1934） pursued the objective of reformulating psychological theory. His historical-cultural analysis of the ＂crisis in psychology＂ showed that, beyond contradictions between the two main methodological currents---＂objective/explanatory＂ and ＂subjective/intuitive＂--psychology is primarily influenced by its empirical-sensory foundations. This influence is actually at the origin of the disagreement since it maintains the obligation for the two currents to make reference to empirical-sensory data. Only a general model of the developing human being, assessed by its usefulness, will allow reorienting psychology towards a broader science. This would lead to a general theory of psychology, which could then facilitate the search for tools for an indirect method enabling it to go beyond empiricism.

Evolution of research methods in Psychology

psychology has more than 100 years developmwnt history, and make great success during this time. But in the after development, psychology met the unprecedented contradiction and conflict, facing division and broken, and in the embrassmed situation of divorced from society, positive psychology is emerge as the times requirement in this crisis. In order to better guide the development to positive psychology, providing philosophical theory and instructions on methodology,it is neeessary to discuss about the positive psycholog from a philosophical perspective. Since 1879 the western modern psychology come into being, the psychology of natural science orientation has been the mainstream of psychology. In addition, admit the uniqueness of man, attention to people＇s inner experience of humanistic psychology, also occupies a space in the confrontation with the reflection of the mainstream of scientific psychology, positive psychology from the research content to lead psychology to another port, but the research methods are not completely abandon the previous research methods of positivism psychology, but more introduced humanism based on the oositivism research method of scientific oriented.

The Intercultural and Psychophysical Pedagogy of Phillip Zarrilli

Phillip Zarrilli is an acting teacher whose pedagogy incorporates the Asian disciplines of hatha yoga, kalarippayattu, and t ＇ai chi ch ＇uan. His intercultural pedagogy would be best labeled as ＂psychophysical＂ based on his own assertions and when bearing in mind the traditions that he considers most personally influential, all of which have intercultural elements, both Western and Asian. This paper examines Zarrilli＇s personal origins, his pedagogy, his teaching influences, and his legacy based on his artistic progeny. Information was gathered through interviews, personal observation, on-site participation, and literature. The subjects of these analyses were： the disciplines of Asian origin relevant to Zarrilli＇s pedagogy; how his teaching influences his students; Zarrilli＇s personal development from university to his present international teaching, directing, and writing; his past and current projects; and what his work means today.

Cultural Psychology： An Interdisciplinary Perspective

Cultural Psychology emerged as an interdisciplinary subfield roughly in the 1980s/1990s. With about thirty years of momentum, this discipline has grown from little more than a special interests group to a topic to which multiple institutions and journals have been dedicated. This paper presents an outline of the discipline of Cultural Psychology from an American interdisciplinary perspective. The pitfalls of General Psychology （research methodology, politicization, and an essentialist hermeneutic） and Anthropology （an epistemological gap in the four fields approach, psychophobia, and the role of the researcher in cultural change） are addressed, in turn. Cultural Psychology provides an alternative to these pitfalls by drawing on the strengths of each discipline to address both theoretical and empirical problems. Cultural Psychology urges for a critical reflection on the social structure and history of its own discipline, resulting in a broader academic canon and a more nuanced understanding of interdisciplinary relations within the human sciences.

Analysis of the Story-Line Behind Selected Hausa Proverbs

Proverbs which are short witty traditional oral expressions handed down from generation to generation as a common heritage is also believed to be true expressions of the Hausa people＇s philosophy. This philosophy is clad in different ways by the people as they are continuously at work to give meanings to their creative activities. Proverbs are one of the most relevant expressions of human wisdom and knowledge of nature, psychology, and reality for the Hausa people of Northern Nigeria; however, the images that are presented in the proverbs are culturally defined and they may differ from place to place, as well as from generation to generation. Proverbs are capable of a variety of meanings, according to how and when they are used. These findings have revealed that many popular and interesting Hausa proverbs tell a condensed story; these stories give vivid illustrations which help the hearer understand the proverbs. In this paper, the author attempts a deep intellectual analysis into the story-lines behind the emergence of some selected Hausa proverbs, with a view to comprehending and propagating embedded ideas and cultural principles or philosophies that may be relevant for contemporary social usage.

Psychological and Philosophical Readings of the Spectatorship of Bollywood and Indian Tamil Film in Sri Lanka

The objective of this study is to explore the psychic, moral, ethical and logical significances in the spectatorship of Bollywood and Tamil film in the Sri Lanka. Bollywood and Tamil film has been taking a very popular cultural performance in Sri Lanka. The original Indian spectatorship of these film traditions has been diverted by the cultural and political psychology of Sri Lanka. Hence, this local orientation of the Indian cinema remains a quite metamorphosis and deconstruction in its appreciation and screening in terms of the social, cultural and political features that deeply-rooted in Sri Lankan history, culture and geographical limitations. For this study, several film texts, which include typical Bollywood and Tamil film characteristic features were used and observed on how they have been absorbed in the Sri Lankan cultural society. And on the other hand, some audience surveys specific to different film appreciation contexts were conducted. They included urban slums, semi-rural Muslim societies, north and east areas of Tamil villages, Colombo urban society, Tamil state areas and Kandyan Sinhala rural villages. In the textual analysis of the film content, implicit psychological narrations and their social and aesthetic interpretations were revealed in the analytical explanations. Using the audience surveys, many different opinions that can be traditionally filtered in the screening and appreciation of these film traditions specific to their living cultural settings were also identified. In conclusion, perception in Sinhala film has been considerably designed by the experience of Bollywood and Tamil film spectatorship is deducted by this study. Hence, not only this social trend affected to the appreciation of film in local general audience but also in all the facets of film production （script writing, shooting, acting, dialoguing, music and choreography and screening） has also significantly being influenced by the Bollywood and Tamil film. As a result of this evolution of local film culture, most recent trend in Sinhala film noir is also being followed by the early subjective consequences of Bollywood and Tamil film culture in Sri Lanka.

Androgen actions on endothelium functions and cardiovascular diseases

The roles of androgens on cardiovascular physiology and pathophysiology are controversial as both beneficial and detrimental effects have been reported. Although the reasons for this discrepancy are unclear, multiple factors such as genetic and epigenetic variation, sex-specificity, hormone interactions, drug preparation and route of administration may contribute. Recently, growing evidence suggests that androgens exhibit beneficial effects on cardiovascular function though the mechanism remains to be elucidated. Endothelial cells （ECs） which line the interior surface of blood vessels are distributed throughout the circulatory system, and play a crucial role in cardiovascular function. Endothelial progenitor cells （EPCs） are considered an indispensable element for the reconstitution and maintenance of an intact endothelial layer. Endothelial dysfunction is regarded as an initiating step in development of atherosclerosis and cardiovascular diseases. The modulation of endothelial functions by androgens through either genornic or nongenomic signal pathways is one possible mechanism by which androgens act on the cardiovascular system. Obtaining insight into the mechanisms by which androgens affect EC and EPC functions will allow us to determine whether androgens possess beneficial effects on the cardiovascular system. This in turn may be critical in the prevention and therapy of cardiovascular diseases. This article seeks to review recent progress in androgen regulation of endothelial function, the sex-specificity of androgen actions, and its clinical applications in the cardiovascular system.

On the theoretical basis of linguistics and modem cultural studies

Language study is closely related to the ecological literature and cultural studies. The predicament of modern ecological literature and cultural theory is that there no linguistic theory to rely on. Biolinguistics emphasize the two-way interaction between language and environment, regard language as the intermediate link between nature and culture. It combines the ＂environment＂ of language with nature and social psychology. Thus this theory studies beyond such one-way determinism of traditional linguistics as ＂the world constructed language＂ or ＂language of the construction of the world,＂ concerning the relationship between language and the world. It also goes beyond the dualism of ＂naturatness＂ of language and ＂agreement＂ of the issue to become the real eco-dialectical linguistic theory with rich ＂argument＂ . This theory can help people better understand the relationship between text and the world, nature and culture, natural ecology and social spiritual ecology. Therefore it is a basic theory of modern literature, cultural studies, as well as one of the most leading and challenging issue for the study of ecological poetic and culture abroad.

Transition psychology： the membership approach

China＇s social transformation since reform and opening up in 1978 has provided a unique social laboratory for Chinese researchers of social psychology. In order to describe, understand and interpret the psychological and behavioral logic of the Chinese people, we need to call on social psychology research or social transition psychology research that looks directly at social transition, in order to go beyond the cultural exceptionalism and static society approaches. Multiple group membership is the potential core construct of such a psychology.
