Computational analysis of genetic loci required for amphid structure and functions and their possibly corresponding microRNAs in C. elegans

Objective To examine the important roles of microRNAs （miRNAs） in regulating amphid structure and function, we performed a computational analysis for the genetic loci required for the sensory perception and their possibly corresponding miRNAs in C. elegans. Methods Total 55 genetic loci required for the amphid structure and function were selected. Sequence alignment was combined with E value evaluation to investigate and identify the possible corresponding miRNAs. Results Total 30 genes among the 55 genetic loci selected have their possible corresponding regulatory miRNA（s）, and identified genes participate in the regulation of almost all aspects of amphid structure and function. In addition, our data suggest that both the amphid structure and the amphid functions might be regulated by a series of network signaling pathways. Moreover, the distribution of miRNAs along the 3＇ untranslated region （UTR） of these 30 genes exhibits different patterns. Conclusion We present the possible miRNA-mediated signaling pathways involved in the regulation of chemosensation and thermosensation by controlling the corresponding sensory neuron and interneuron functions. Our work will be useful for better understanding of the miRNA-mediated control of the chemotaxis and thermotaxis in C. elegans.

Analysis of the major components of root exudates released from several economic forest tree using GC-MS

In 2000 and 2001, 1-year-old seedlings of 7 economic tree species including chestnut, apricot, persimmon, peach, walnut, pear and apple were cultured in garden pots that had a diameter of 40 cm and were filled with clean sand. The major components of exudates released from their roots were isolated and analysed by GC-MS. Totally 200 kinds of organic chemicals were isolated, of which 3 kinds i.e. naphthalene, dimethylbenzene and dibutyl phthalate were principally controlled pollutants according to 'Blacklist of Principal Environment Pollutants in China' and the standard of U.S. Environmental Protection Agency (EPA). The research result provided theoretical evidence for selecting low-pollution economic forest crops in the water source protection area in Miyun Reservoir.

Feasible economic strategies to improve screening compliance for colorectal cancer in Korea

ABM: While colorectal cancer (CRC) is an ideal target for population screening, physician and patient attitudes contribute to low levels of screening uptake. This study was carried out to find feasible economic strategies to improve the CRC screening compliance in Korea. METHODS: The natural history of a simulated cohort of 50-year-old Korean in the general population was modeled with CRC screening until the age of 80 years. Cases of positive results were worked up with colonoscopy. After polypectomy, colonoscopy was repeated every 3 years. Baseline screening compliance without insurance coverage by the national health insurance (NHI) was assumed to be 30%. If NHI covered the CRC screening or the reimbursement of screening to physicians increased, the compliance was assumed to increase. We evaluated 16 different CRC screening strategies based on Markov model. RESULTS: When the NHI did not cover the screening and compliance was 30%, non-dominated strategies were colonoscopy every 5 years (COL5) and colonoscopy every 3 years (COL3). In all scenarios of various compliance rates with raised coverage of the NHI and increased reimbursement of colonoscopy, COL10, COL5 and COL3 were non-dominated strategies, and COL10 had lower or minimal incremental medical cost and financial burden on the NHI than the strategy of no screening. These results were stable with sensitivity analyses. CONCLUSION: Economic strategies for promoting screening compliance can be accompanied by expanding insurance coverage by the NHI and by increasing reimbursement for CRC screening to providers. COL10 was a cost-effective and cost saving screening strategy for CRC in Korea.

R/S AND WAVELET ANALYSIS ON EVOLUTIONARYPROCESS OF REGIONAL ECONOMIC DISPARITY IN CHINA DURING PAST 50 YEARS

This paper shows the dynamic process of regional disparity of economic development in China in the past 50 years from a new insight by using the rescaled range statistic (R/S) analysis and wavelet analysis of the Theil index sequence with different time scales. The main conclusions are: 1) The regional disparity of economic development in China, including the inter-provincial disparity, inter-regional disparity and intra-regional disparity, has existed for many years. Theil index by the comparative price has revealed the true trend for comparative disparity of regional economic development from 1952 to 2000. 2) Decomposition of Theil index indicates that the dynamic trend of comparative inter-provincial disparity in the coastal region is in line with dynamic trend of inter-provincial disparity in the whole China. 3) The R/S analysis results tell us that during 1966-1978, the Hurst exponent H=0.504 approximate to 0.5, which indicates that in that period the evolution of comparative inter-provincial disparity of economic development showed a random characteristic, and in the other periods, i.e. 1952-1965, 1979-1990 and 1991-2000, the Hurst exponent H>0.5, which indicates that in those periods the evolution of the comparative inter-provincial disparity of economic development in China had a long-enduring characteristic. 4) By using wavelet analysis at different time scale, we arrived at a conclusion that the evolutionary process of the disparity of economic development of China is not a simple inverted U shape but a compound of several U shapes. The result tells us that the evolutionary plot of inter-provincial disparity in China follows the inverted U on the whole at the higher scale, 24 ( 16 years). That is to say, the disparity tends to rise in the first stage of economic development, and fall slowly over the peak in the second stage of economic development. However, if we shorten the time scale to 23 ( 8 years), then a link of several U shapes will appear.

How expensive is inflammatory bowel disease? A critical analysis

Economic analysis of chronic diseases is required for proper allocation of resources and understanding costeffectiveness studies of new therapies. Studies on health care cost of ulcerative colitis （UC） and Crohn＇s disease （CD） are reviewed here. These studies were carried out in various countries with disparate health care systems. In the United States, data were often modeled or retrieved from large insurance schemes. Surgery and in-patient hospitalization accounted for over half the outlay on UC and CD. Fistulous disease in CD and parenteral nutrition were very costly. In Canada, overall charges were lower than in the United States, but there too, surgical costs were relatively high. In European studies, economic data were abstracted directly from patients＇ files. One pan-European study examined the outlay on UC and CD in a community-based prospective inception cohort followed for 10 years. Overall costs in Europe were lower than in the United States. Surgery, hospitalization, year of follow-up, disease phenotype in CD and ASCA-positivity impacted significantly on costs. In all studies, the cost data were right skewed, aminosalicylates were expensive drugs, and biological agents the most expensive; moreover indirect costs were not calculated. Infliximab raised costs considerably in CD, but there were no long-term followup studies, so that the cost-benefit of biological agents remains unknown. In conclusion, costs of managing UC and CD vary by country, surgery, genotype and several other factors. The most important question for further research is whether the biological therapies are cost-effective in the long-term.

Determinants of Female Employment Rate in the European Union

The aim of this paper is to provide a clear insight about the determinants of female employment rate in the European Union where we have used panel data analyses of 27 countries members of the European Union from 1995 till 2009. Applying dynamic modeling, i.e, generalized method of moments （GMM） econometrics findings have driven us to system estimated model where the following institutional variables have been tested： maternity leave, child care facilities, college education, fertility rate, GDP growth, female unemployment rate and part-time employment. We expect these variables to have a positive impact on the female employment rate except for the female unemployment rate and maternity leave

Prediction for asphalt pavement water film thickness based on artificial neural network

In order to study the variation o f the asphalt pavement water film thickness influenced by multi-factors,anew method for predicting water film thickness was developed by the combination o f the artificial neural network(ANN)a d two-dimensional shallow water equations based on hydrodynamic theory.Multi-factors included the rainfall intensity,pavement width,cross slope,longitudinal slope a d pavement roughness coefficient.The two-dimensional hydrodynamic method was validated by a natural rainfall event.Based on the design scheme o f Shen-Sha expressway engineering project,the limited training data obtained by the two-dimensional hydrodynamic simulation model was used to predict water film thickness.Furthermore,the distribution of the water film thickness influenced by multi-factors on the pavement was analyzed.The accuracy o f the ANN model was verified by the18sets o f data with a precision o f0.991.The simulation results indicate that the water film thickness increases from the median strip to the edge o f the pavement.The water film thickness variation is obviously influenced by rainfall intensity.Under the condition that the pavement width is20m and t e rainfall intensity is3m m/h,t e water film thickness is below10mm in the fast lane and20mm in t e lateral lane.Athough there is fluctuation due to the amount oftraining data,compared with the calculation on the basis o f the existing criterion and theory,t e ANN model exhibits a better performance for depicting the macroscopic distribution of the asphalt pavement water film.

The expansion and limitation of behavioral finance research methods

Behavioral finance inherits the standard research methods in the finance, and it makes outstanding contribution to leading the experimental research into the field of finance. It uses the cognitive science as the method guide to expand its scientific research tools. On one hand, the intelligent development of the cognitive science provides an important and effective means of a tool for the behavioral finance research; on the other hand, precisely because behavioral finance theories of progress makes a certain extent, dependent on the modem cognitive science research results and thus the development of cognitive science, its results application and limitation will be confined to a direct impact on the development of behavioral finance. That is why we need an in-depth study of the new method of behavioral finance research and grasps their limitations.

Cytogenetic and Clinical Analysis of 340 Chinese Patients with Primary Amenorrhea

Objective To analyze the relationship between karyotypes and clinic features of patients with primary amenorrhea.Methods G banding was done for 340 patients with primary amenorrhea to facilitate individual chromosome identification,and if specific staining for certain portions of the chromosome was necessary,C banding was used.The clinical data were recorded by physical examination and ultrasound scanning.Results Karyotype analysis of the 340 patients revealed that 180(52.94%) patients had normal female karyotypes and 160(47.06%) patients had abnormal karyotypes.The abnormal karyotypes included abnormal X chromosome(150 patients),mosaic X-Y chromosome(4 patients),abnormal autosome(5 patients),and X-autosome translocation(1 patient).The main clinical manifestations in patients with primary amenorrhea were primordial or absent uterus(95.9%),invisible secondary sex features(68.8%),little or absent ovary(62.6%),and short stature(30.0%).The incidence of short stature in patients with X chromosome aberration(46%,69/150) was significangly higher that in patients with 46,XX(9.44%,17/180) as well as 46,XY(6.67%,3/45;χ2=146.25,P=0.000).All primary amenorrhea patients with deletion or break-point at Xp11.1-11.4 were short statures.Conclusions One of the main reasons of primary amenorrhea is choromosome abnormality,especially heterosome abnormality.It implies the need to routinely screen chromosomal anomalies for such patients.There might be relationship between Xp11.1-11.4 integrity and height improvement.

Self-Regulated Reading Comprehension Strategy Selection Through Diagnostic-Prescriptive Instruction： A Case Study

This demonstration of concept applies diagnostic-prescriptive reading instruction, a methodology useo m omteu atd^u~ developmental education, toward improving reading comprehension and self-regulated comprehension strategy selection in Chinese postsecondary education. A single tutor, also the researcher, works closely with one Chinese university student to develop student-centered comprehension strategies that she can practice on her own. After a battery of formal and informal assessments and interviews, decoding and understanding deficiencies are identified, characterized, and discussed. Both the student and her tutor develop and execute a study plan, which was completed during the spring semester of 2010 at Sha＇anxi University of Science and Technology （SUST） in Xi＇an, People＇s Republic of China （PRC）. By focusing on the subject＇s primary decoding deficiency, spelling, and her primary understanding deficiency, lack of background knowledge, the subject and her reading tutor are able to strategically tackle five reading comprehension goals： （1） spelling; （2） phonemic awareness; （3） noticing structural and cohesive elements; （4） comparing argumentative and evaluative texts; and （5） analyzing expository texts in business and economics. A final discussion analyzes both qualitative and quantitative data, including unexpected discoveries such as the salience of cohesion in reading comprehension and the cultural biases of standardized reading assessments.

Biological Analysis of HSV-1 Immediate-early Proteins ICP0, ICP22, and ICP27 in Neuroblastoma Cells

The three immediate-early proteins of HSV-1, ICP0, ICP22, and ICP27, have specific and pivotal functions in transcriptional activation and inhibition, multiple regulatory and control processes of viral genes. In this paper, the expression and localization of these three proteins were studied in neuroblastoma cells using biochemical assays, and their possible and potential interactive functions are discussed. The data show that the three proteins are localized in different structures, specifically in the PML-NB-associated structure, which is a specific nuclear structure composed of many protein molecules and bound tightly to the nuclear matrix in neuroblastoma cells. The results suggest that the activating and suppressive functions of ICPs are mostly dependent on their transcriptional and regulatory roles, including the PML-NB-associated structure.

Effect of Inhalation of Essential Oil of Rosa Demascena Mill. on Psychomotor Functions in Human

Some studies document that odorants influence in sympathetic and parasympathetic nervous systems, and neurophysiological brain activity. Odors compounds can act on the neuroendocrine system, neurotransmitters and neuromodulators, influencing psychological behavior as well as body function. The study was conducted in 20 individuals in each test to analyze the effects of essential oil inhalation on psychomotor performance in the healthy volunteers. Two tests were performed in the present study （1） SLCT （six letter cancellation test） and （2） DLST （digit letter substitution test）. These tests were carded out for the assessment of psychopharmacological activity of essential oil of Rosa damascena Mill., in healthy young human individuals belonging to the age group 18 to 22 years. The results of the psychomotor performance test in healthy human individuals revealed that there was improvement in psychomotor functions.

The Interpretation of the Reference of ＂Now＂ in Written Messages： An Experimental View

The semantics of pure indexicals ＂I,＂ ＂here,＂ and ＂now＂ has been discussed in the area of philosophy of language. According to David Kaplan, in face-to-face communication, ＂I,＂ ＂here,＂ and ＂now＂ refer respectively to the agent, the place, and the time of the context of utterance. In recorded and written messages, however, the identification of pure indexical references is nontrivial, given that there is a gap between the time of utterance and that of interpretation. In the literature, four major views are proposed from a philosophical perspective. While these are theoretically competing, no empirical data or pragmatic analyses have been provided. How is the reference of ＂now＂ in written messages interpreted？ Which views proposed in the literature are supported empirically？ This paper investigates these questions from experimental and pragmatic perspectives.
