The purpose of this study is to investigate the function of a novel potassium transporter gene (NrHAK1) isolated from Nicotiana rustica roots using yeast complement and real-time PCR technique. The complementary DNA (cDNA) of NrHAK1, 2 488 bp long, contains an open reading frame (ORF) of 2 334 bp encoding a protein of 777 amino acids (87.6 kDa) with 12 predicted transmembrane domains. The NrHAK1 protein shows a high sequence similarity to those of high-affinity potassium transporters in Mesembryanthemum, Phytolacca acinosa, Arabidopsis thaliana, and so on. We found that the NrHAK1 gene could complement the yeast-mutant defect in K+ uptake. Among several tissues surveyed, the expression level of NrHAK1 was most abundant in the root tip and was up-regulated when exposed to potassium starvation. Moreover, the transcript accumulation was significantly reduced by adding 5 mmol/L NH4+ to the solution. These results suggest that NrHAK1 plays an important role in potassium absorption in N. rustica. 展开更多

Changes in distribution density,morphology and secretory content of endocrine cells in the gastro-entero-pancreatic system of black-spotted frogs Rana nigromaculata before and after fasting were investigated using immunohistochemistry and antisera to six gut hormones.Six types of endocrine cells were detected in the digestive tract of Rana nigromaculata,including 5-hydroxytryptamine(5-HT),gastrin(GAS),somatostatin(SOM),glucagon(GLU),pancreatic polypeptide(PP)and vasoactive intestinal polypeptide(VIP)cells.After fasting,the density of 5-HT cells in the esophagus,cardia and fundus,GAS cells in the fundus and pylorus,PP cells in the fundus decreased significantly(P<0.01),while SOM cells in the cardia,GLU cells in the rectum increased significantly(P<0.01).The cytoplasmic processes of 5-HT cells became shorter or not detectable.The secretory content of GAS cells reduced in the cardia.The positive immunostaining reaction in the perinuclear region of SOM cells in the cardia,fundus and pylorus became weaker,while the staining intensity in the periphery of these cells became stronger.VIP cells were not detectable in the whole digestive tract after fasting.Five types of endocrine cells were found in the pancreas of Rana nigromaculata,including 5-HT,GAS,SOM,GLU and PP cells.After fasting,the density of 5-HT cells decreased slightly(P>0.05),while SOM,GAS,GLU and PP cells increased significantly(P<0.01).Furthermore,the secretory content of GLU cells increased significantly.Considering their functionalities,our results indicate that the changes of GEP endocrine cells in Rana nigromaculata responded adaptively to starvation-induced stress. 展开更多

The present study was designed to investigate the potential protective effect of melatonin as an antioxidant separately or in combination with antigens (cerearial; CAP or soluble worm; SWAP) against Schistosoma mansoni infection in hamsters. Each hamster was sensitized with an initial immunization of 0.6 ml of the extracted antigen (30μg protein/mL). After four days, a second injection of 0.4 mL was given (20μg protein/mL). Then, each hamster was exposed to 260 ± 20 S. mansoni cercariae followed with melatonin treatment (3.5 mg/kg) for thirty days from the 1st day of post infection. Levels of lipid peroxidation (LPO) products, eatalase (CAT) activity, hepatic glutathione (GSH) and biochemical changes in the liver and kidneys functions were investigated. The results revealed a high significant increasing of LPO and decreasing of CAT and GSH in liver of infected hamsters. Biochemical observations showed severe damage in the liver enzyme activities and increasing cholesterol level in infected animals. Melatonin co-treatment with antigen to the infeeted-hamster attenuated the increase of LPO and restored the activity of CAT and levels of hepatic GSH. Also, the biochemical damages in the liver and kidneys funetions were reduced. The present study suggests that melatonin may be useful in combating free radical-induced damage due to infection toxicity. The immunization with previous antigens resulted in a remarkable improvement on the liver enzyme activities, which were increased after infection. Thus, vaccination of hamsters with antigens (both CAP and SWAP) and melatonin treatment has more potent effect on the enhancement of antioxidant and biochemical of S. mansoni infected-hamster than each treatment separately. Immunization of the hamster with SWAP followed by melatonin was the best way among the other regime treatments to improve the biochemical and antioxidant parameters of the infected-hamsters. 展开更多

Objective: To get the message of knowledge and attitude about pain of the medical members from basic medi- cal service sites by questionnaire investigation. To point out concrete directions for generalization and post-education of the three-tiered principles of analgesics treatment of WHO. Methods: We designed a questionnaire about cancer pain treatment. We used it to make inquire in 1040 medical staff from different medical agencies. SPSS software was used to analyze all data. Results: 1027 questionnaires were fit for data analysis. 91.4% of staff working in the primary medical agencies, 95.0% with professional title of assistant professor or lower title, and 83.7% younger than 50-year old. The data displayed that basic knowledge of cancer pain are poorly mastered. More than half investigates cannot evaluate the pain degrees correctly, and have many erroneous understandings about pain. Conclusion: The training of pain treatments for the medical staff working in primary medical agencies should be enhanced because of their poor grasping. Primary agencies should increase the varieties of analgesic drugs and change their attitude and conception of analgesic drugs administration. 展开更多

This study employed an innovative meth- odological framework that combines geomatics and conventional survey methods to monitor changes in forest conditions and examine their associations with local forest governance parameters in a mountain watershed covering 153.3 km2 in the middle moun- tains of Nepal. The study involved two spatial scales and analytical steps. First, geomatics techniques were used to map and detect changes in major land cover types in the watershed between 1976 and 2000 and to analyze relationships between forest cover changes and governance arrangements. This was followed by micro-level analysis of the relationships between the biological conditions of selected forests within the watershed and their governance arrangements, using conventional survey methods and analytical tools. The findings show that forest cover in the watershed in- creased by about 15 per cent during the period. The rate of increase in forest cover was highest in areas under a semi-government type of governance ar- rangement, while the community forests were gener- ally better in terms of current biological conditions compared to the semi-government forests. This in- consistency between the findings from the two analy- ses does not allow us to draw any firm conclusions regarding the role of property rights in determining forest condition, but it indicates that the outcomes of local forest management initiatives may be more de-pendent on local institutional arrangements regulat- ing forest use and maintenance of forest resources than on the type of property rights arrangements. The findings also provide evidence of the methodological suitability of the research approach adopted, which may be useful for addressing many other research questions related to forestry and natural resources management, particularly those involving multiple spatial scales. 展开更多

This study attempts to investigate if and how students' perceptions regarding the first accounting course related with the selection of accounting as a major. Moreover, it examines students' initial perceptions and course performance regarding the introductory accounting course. Participants in this study were 120 students from Technological Educational Institute of Kavala, School of Business and Economics (3 departments), who were asked to complete a survey instrument. The instrument used eleven statements regarding students' perceptions (such as difficulty and motivation of the course) of the first accounting course. The main factors affect students' decisions to follow accounting and seem to be similar with other researchers' findings (Geiger & Ogilby, 2000). Future research could be used larger sample from different countries and the survey could also be used for a longer time period. 展开更多

Background and aims: Patient plays an important role in preventing the adverse events (AEs) and harms occurredduring medical care; however, the incidence of AEs and harms can be effectively reduced if patients actively andsuccessfully participate in their care. Organizations of safety management for patients and authorities of health systemagree that involve patients into the management on their care can obviously prevent medical error; whereas, the attitudesand actual actions of hospitalized patients for the view remain controversial. In this study, we aimed to explored patients’attitudes and actual actions participate in their own safety and whether patients with positive attitude are more likely totake action than others? Methods: In the present cross-sectional study, convenience sampling method was adopted torecruit a sample size consist of 2052 patients from two teaching hospitals affiliated to Medical College of ShantouUniversity located in Shantou China. We used a questionnaire consist of 7 items to investigate the attitudes and actualactions of hospitalized patients participating in their care. Then the actual actions between patients with positive andnegative attitudes were analyzed using descriptive analysis and independent t-test. Results: Most patients have a positiveattitude on engaging in their safety management activity. Although most patients have positive attitude, fewer can takeactual actions. Patients with positive attitude are more likely to take actions, but there are not statistical significantdifference for positive and negative attitudes patients in terms of some items, such as “Ask doctor or nurse to wash theirhands” and “Ask nurse or doctor to confirm your identity”, etc. Conclusions: Positive attitude is an important factor thatimproves the rate of participating in the medical care activity for patients. Based on the results of current study,interventions that improve the attitude of patient are needed to improve patients’ attitude and what is more important ishow to convert attitude into actual action. When making plan of interventions, cultural background of patients need to betaken into account. 展开更多

In furtherance of their most recent research on the textbook of the course LC (language and communication) 4001 Reading Skills Development in English for Graduate Studies (2012), the co-authors carried out a follow-up work on read-aloud approach as some students voiced a sense of dissatisfaction with regard to such means which was primarily used in the LC 4001 class taking place from August 8 to November 27, 2012. In the current study, the data were garnered from 37 students enrolling in LC 4001 from January 8 to May 7, 2013. Based on the questionnaire, the findings revealed that a large number of the English reading learners acknowledged the mounting importance of English as a linguafranca in the region of 84% and 16% at the "most" and "much" levels, respectively. Likewise, around 90% of the participants had a positive attitude toward such pedagogical method, while only 10% disliked it. Concerning the academic reading curriculum for higher English reading competence, students' different language learning backgrounds and personal excitement caused by reading-aloud activities should be taken on board. Any activity introduced into the classroom should be explicitly stated to the students at the beginning of the course. Using any instructional approach without clear explanations or precautions may seriously upset learners partially or even completely obstruct their effective learning 展开更多

The study determined the research priorities in Swaziland agricultural sector. Data collection used existing documents on agricultural research prioritizing, Nominal Group Technique and modified Delphi technique, with analysis of data using content categorization and, group and individual ranking of submissions. Findings showed the agricultural priorities from national policies are tied-up with mitigating the effects of HIV and AIDS on food security, reduction of poverty and, sustainable development. The findings also revealed forty-three field crops areas needing research. Seven horticulture areas and eleven livestock sector areas were of high priority. A considerable number of research areas in field crops, horticulture and livestock indicated that the current research system has not adequately addressed research needs, despite efforts made by the private sector, University of Swaziland and Ministry of Agriculture and Cooperatives, for Swaziland to achieve self-sufficiency in food production. Recommendation was that the identified research priorities should be used as basis for directing the limited resources in conducting agricultural research. The participation of all stakeholders would facilitate efficient use of resources and facilitate collaboration amongst research institutions. The University of Swaziland should develop research priorities aligned with national policies and objectives, to facilitate funding for research by both government and donor agencies. 展开更多

Revision is an important part of writing process but it often baffles the researchers due to the difficulties in recording the revision process of students. Based on a self-made questionnaire and the online record of the revision process, this study describes the English learners' revision behaviors and process in their second semester of a two-year writing course. The analysis indicates that the English learners hold a positive attitude towards revision and but passive in resorting to outside sources for help. The source of the feedback has a great influence on their motivation of revision. On the other hand, although they use all types of revision operations, they concentrate on surface changes and simple operations. 展开更多

Several studies have investigated how to use learning games to improve inquiry abilities. However, not every learner favors this kind of approach. Thus, we need to examine how human factors affect learners' reactions to the use of a digital game to support inquiry-based learning. This study addressed this issue by developing a digital game, "Baking Town", and using the game to examine the effects of two central human factors, sex differences and problem-solving strategies, on students' performance. The results demonstrate that students' inquiry abilities were significantly improved after they participated in the digital game. The results also demonstrate that the digital game may be a feasible way to reduce differences between boys and girls in this domain. Finally, we used the findings to develop a framework that can be used to enhance our understanding of sex differences and the use of problem-solving strategies in the context of digital games. 展开更多

The aim of the research in the paper was to study redlining practice within the greater Johannesburg area. The aim can be summarised by the following objectives: firstly, to investigate the evidence of redlining in the Greater Johannesburg area and to test its existence; secondly, to investigate the reasons why the areas were redlined; thirdly, to understand what the South Africa government and society did to combat the redlining practice. The research methodology was based on a questionnaire and interviews. A pool of respondents from the Greater Johannesburg suburbs that had interest or were affected by the practice of redlining was sought and interviewed. Analysis of the responses was made and conclusions were drawn from the responses. Secondary data was also sought from publications on the redlining practice to support the primary interviews data. From the interview responses and the secondary data, it was established that redlining existed in Greater Johannesburg and that the areas where redlining was practised could be marked on a map. 展开更多

Budget emphasis, leadership behavior structure and consideration, and effectiveness of audit review were examined as antecedents of attitudes toward DAB. The findings produced consistent evidence in support of the theoretical model. It is not an emphasis on meeting budgets that leads to undesirable behavior, but contextual variables, such as leadership behavior structure and effectiveness of audit review. 展开更多

A total of 10 K-12 teachers enrolled in one graduate course participated in this study. They received lectures, took practices and exercises of Scratch programming and were then asked to design and implement their projects before the semester. It was found that teaching programming concepts to K-12 teachers with Scratch is feasible. K-12 teachers with less computer background can learned basic programming concepts and applied them in their project code implementation. Although no significant difference was found between participants' pre-test and post-test on programming self-efficacy, positive attitudes toward learning Scratch programming was revealed in the questionnaire survey and results of interviews. This study paves a way for referring to the teaching of programming concepts for K- 12 teachers. 展开更多

This action research explores the use of the flipped classroom approach in an English speaking class with 25 students at intermediate level in a vocational college in China's Mainland. It aims at motivating English learners and helping them develop communicative language skills more effectively and efficiently. Both qualitative and quantitative methods are adopted to analyze the data collected through interviews, teaching logs, as well as anonymous questionnaires and a summative assessment. Results show that the flipped classroom approach does stimulate students to invest more time and effort prior to instruction and during class learners do participate in communicative language exercises more enthusiastically. As a result, conceivable progress has been made in learners' performance. Possible recommendations of incorporating periodic rotation within the class, adding certain teacher-led instruction, and informal evaluation with group members, are raised at the end of the paper to help further improve the teaching/learning outcome of the flipped classroom approach. 展开更多
