The nature of the relationship is based on the principle of consensus, voluntary with the highest goal of economic prosperity on the basis of political harmony and socio-cultural development in the effective cooperation of the direct actors. Vietnam with its geographic and cultural features in Southeast Asia has had a certain relationship with the Silk Road in the past and with APEC in the present and in the future. From that angle of view, positive ideas can be found about the factors that contribute to the sustainable development of nations, the whole region in particular, and the whole world in general.展开更多

We, therefore, conducted field surveys to investigate factors related to growth and mortality rates of bottom-cultured scallops after release. Specifically, we focused on the effects of total antioxidant capacity (TAOC) and three key enzymes involved in antioxidant and metabolic function:glutamic pyruvic transaminase (GPT), lactic dehydrogenase (LDH), and superoxide dismutase (SOD). Across summer and winter, we also measured the relative mRNA expression of GPT and SOD to understand their seasonal variation in the scallops, along with how such variation correlated to growth and mortality. Results show that bottom cultured scallops experienced mass mortality during the first six months post-release. During winter (December), scallops grew more rapidly and suffered less mortality than in summer (August). The observed lower performance probably resulted from less advantageous environmental factors during the summer seasons, such as high temperature and low dissolved oxygen. These environmental stressors enhance protein consumption while decreasing energetic resources in scallops. Furthermore, scallops in summer exhibited high antioxidant levels that probably competed for energy with process integral to growth and survival. These negative factors combined to elevate mortality rates. In conclusion, we provided evidence suggesting correlations between metabolic/antioxidant activity and growth and mortality of bottom-cultured yesso scallops. These correlations implied us an accurate method to estimate the performance of bottom culture system. Suggestions about innovative aquaculture techniques were also discussed in the study. Our results might provide a possible guideline to the improvement of bottom culture techniques for this commercially valuable seafood species.展开更多

This study examined cross-cultural performances on motor competence and health-related fitness between Portuguese and U.S.children.Methods: Portuguese(n = 508; 10.14 § 2.13 years, mean § SD) and U.S.(n = 710; 9.48 § 1.62 years) children performed tests of cardiorespiratory fitness(Progressive Aerobic Cardiovascular Endurance Run), upper body strength(handgrip), locomotor skill performance(standing long jump), and object projection skill performance(throwing and kicking). Portuguese and U.S. children were divided into 2 age groups(6à9 and 10à13 years) for data analysis purposes. A twoàfactor oneàway analysis of covariance(ANOVA) was conducted with the Progressive Aerobic Cardiovascular Endurance Run, handgrip, standing long jump scores, kicking, and throwing speed(km/h) as dependent variables.Results: Results indicated that Portuguese children, irrespective of sex, presented better performances in locomotor and cardiorespiratory performance(standing long jump and Progressive Aerobic Cardiovascular Endurance Run) than U.S. children in both age bands. U.S. children outperformed Portuguese children during throwing and handgrip tests. Kicking tests presented gender differences: Portuguese boys and U.S. girls outperformed their internationally matched counterparts.Conclusion: Cultural differences in physical education curricula and sports participation may impact differences in motor competence and fitness development in these countries.展开更多

As meanings generally disperse extensively in different social groups through different associations, they display certain changes in time depending on their usage. Meanwhile, it is hard to define the public relations concept, because it may refer to different meanings even in the same culture. According to the assumptions pertaining to the public relations practices shaping the dominant discourse of the USA, language which produces certain cultural meanings also shapes the way we think and act. Thus, due to its ideological and discursive nature, public relations functions as a culture policy. Being an integral communication management configuring and directing the social sphere and the practices related to it, public relations refers to the concept of habitus introduced by Bourdieu inasmuch as habitus resides in the situations formed by actions that individuals learn throughout their lives. Culture policy; on the other hand, purports the effective participation of people in cultural life, their development in social, economic and cultural areas as well as the creation of convenient conditions to sustain it, which can be achieved with public relations practices. Public relations determines the culture policies in a society with regard to the structured discourses and actions and also acts as the mouthpiece of these policies. The purpose of public communication that is necessary for development and sustainability is to inform the public objectively in cultural, social, political and economic senses by obtaining feedback form them. For the purpose of administering sound public communication strategies in a society, public relations should direct the forms of public discourse. The purpose of this study is to put forth a critical evaluation based on the idea that for the realisation of effective and sensible communication policies in a society, the perception and practice public relations in that society should be regarded as a culture policy. According, this study focuses on whether or not public relations as culture policy serve the development of democracy and public sphere.展开更多

Each installation contains 12 plots of loblolly pine planted at six levels of density from 741 to 4448 trees/ha in combination with two levels of cultural intensity, operational and intensive. The data from 37 viable installations were used to evaluate the crown ratio and relative spacing relationship of loblolly pine plantations. The effects of planting density, site quality, and cultural intensity on the relationship were investigated with a nonlinear mixed-effects modeling approach. The crown ratio and relative spacing relationship is exceedingly predictable. When loblolly pine plantation stands reached the average live crown ratio of 0.40, a critical point representing a generally acceptable level of tree vigor, the corresponding relative spacing index ranged from 0.11 to 0.20, mainly depending on initial planting density. The information about the crown ratio and relative spacing relationship would be useful for selecting the best intensity and timing of thinning.展开更多

Methods: Primarily cultured rat myocardial cells were treated with 10-6 mol/Ladriamycin and 10-6mol/L adriamycin + 10 8mol/I. CGRP. Lactate dehydrogenase (LDH ) activity in the mediumand the contents of malondialdehyde (MDA ). calcium. and magnesium in the myocardial cells were assayed.Results: In the adriamycin group, LDH activity in medium and calcium, MDA contents in myocardial cells weresignificantly increased compared with those in control group, and magnesium content in the myocardial cells wassignificantly reduced. In the adriamycin group. there was a positive correlation between LDH activity in themedium and MDA content in the myocardial cells. Meanwhile, in the adriamycin + CGRP group,- CGRP mightsignificantly reduce the leakage of LDH from myocardial cells, lessen the increase in calcium and MDA contentsand prevent the loss of magnesium. Conclusion: CGRP may inhibit adriamycin induced acute cardiotoxicity byinhibiting lipid peroxidation, attenuating calcium overload, magnesium loss, and protecting enzyme activity.展开更多

Thus, we hypothesized that diabetes-related depression might be associated with damage to the hippocampal neurovascular unit. To test this hypothesis, neurons, astrocytes and endothelial cells were isolated from the brain tissues of rat embryos and newborn rats. Hippocampal neurovascular unit co-cultures were produced using the Transwell chamber co-culture system. A model of diabetes-related depression was generated by adding 150 mM glucose and 200 μM corticosterone to the culture system and compared with the neuron + astrocyte and astrocyte + endothelial cell co-culture systems. Western blot assay was used to measure levels of structural proteins in the hippocampal neurovascular unit co-culture system. Levels of basic fibroblast growth factor, angiogenic factor 1, glial cell line–derived neurotrophic factor, transforming growth factor β1, leukemia inhibitory factor and 5-hydroxytryptamine in the hippocampal neurovascular unit co-culture system were measured by enzyme-linked immunosorbent assay. Flow cytometry and terminal deoxynucleotidyl transferase(TdT)-mediated dUTP nick end labeling staining was used to assess neuronal apoptosis in the hippocampal neurovascular unit. The neurovascular unit triple cell co-culture system had better barrier function and higher levels of structural and secretory proteins than the double cell co-culture systems. In comparison, in the model of diabetes-related depression, the neurovascular unit was damaged with decreased barrier function, poor structural integrity and impaired secretory function. Moreover, neuronal apoptosis was markedly increased, and 5-hydroxytryptamine levels were reduced. These results suggest that diabetes-related depression is associated with structural and functional damage to the neurovascular unit. Our findings provide a foundation for further studies on the pathogenesis of diabetes-related depression.展开更多
