Fifteen sequences from the mitochondrial cytochrome c oxidase subunit I gene (COI) were determined for 4 species of the genus Meretrix, with the homologous sequences ofM. petechialis obtained from the GenBank data library The alignment length of the sequences was 574bp after excluding ambiguous sites, including 93 parsimony informative sites. In the fragments, the percentages of A, T, C and G were 21.15%, 44.71%, 14.05% and 20.09% respectively. There were 12 haplotypes identified: 4 M. meretrix, 2 M. IamarckiL 3 M. lusoria, 1 M. lyrata and 2 M. petechialis. Furthermore, it was revealed that M.. meretrix, M. petechialis and M. lusoria shared some haplotypes. Phylogeny trees were reconstructed by Maximum-parsimony (MP) and Bayesian method using Qylina sinensis as the outgroup. Our results indicated that M. lusoria, M. petechialis and M. meretrix are closely related species. This is in accordance with the viewpoint that M. petechialis and M. lusoria should be treated as a junior synonym of M. meretrix. 展开更多

Found in the Trans-Himalayas of north-west Yunnan and south-east Tibet, the black-and-white snub-nosed monkey (Rhinopithecus bieti) is one of the world’s most endangered primates. A recent survey indicates that only 15 groups with 2500 individuals remain in the wild. However, the Tibetan Xiaochangdu group may be the only equilibrium group in the field since the last investigation in 1988. To evaluate the effects of traditional culture and socioeconomic activity on biodiversity conservation of R. bieti, we conducted a case study in the Honglaxueshan National Nature Reserve in southeast Tibet from June 2003 to May 2005. Interviews, direct observations, and analysis of socioeconomic data indicated major advantages to the conservation of R. bieti, which included that: 1) traditional culture mainly depended on raising livestock and collecting non-timber products rather than forest planting of Tibetan highland barley; 2) religious beliefs, against to kill any wildlife living on the sacred mountain, were mainly influenced by Tibetan Buddhism; and 3) bigger household numbers were induced by the polyandrous marriage system, which resulted in lower per capita resource consumption than smaller ones. 展开更多

With the development of the Internet, the Internet language-a new social variant of language comes into being. Owing to its distinctive features, the Internet language draws extensive attention and evokes dispute. Should we make laws to restrict its development or be magnanimous and tolerant? The present authors think that the dispute reflects the clash between the traditional culture and the "fast food" culture. The two cultures would co-exist harmoniously and co-develop healthily only if we cherish the law in the development of language and grasp the indirect correlation between them. 展开更多

Traditional Chinese vernacular dwellings take root in farming culture with profound connotations. Through analyzing ecological thoughts and cultural ideas in traditional vernacular dwellings, this study aims to provide references for the design of modern vernacular dwellings. It is proposed in this study that ① Ecological thoughts of traditional vernacular dwellings include the simple eco-thought of 'human-nature oneness', Fengshui (traditional Chinese ideas hold that the location of a house or tomb is supposed to have an influence on the fortune of a family) theories of 'balance of yin and yang', energy-saving thought of 'making the best use of local advantages'. Traditional vernacular dwellings are mainly constructed according to local conditions, facing the sunny side and water, backing on the shady side and mountains, with local materials and suitable construction structures for local environment and climatic conditions, which enable residents to enjoy warm winter and cool summer, sufficient sunshine, excellent ventilation and heat-proof, wind and humidity proof, that is, a natural ecological living environment. ② Cultural thoughts of traditional vernacular dwellings include the strict and square philosophical ideas as well as harmonious artistic thoughts. Traditional Chinese vernacular dwellings demonstrate morals and ethics by strict and square patterns and strong sense of hierarchy, most of them have definite axes in spatial patterns to show the hierarchy and core of construction groups; abstract patterns of flower, grass, animal or human beings are also often applied in detailed designs, showing esthetic tastes. The formation of traditional Chinese vernacular dwellings has been closely linked with social and cultural factors, living habits, geographical, water and soil, environmental and climatic conditions as well as folk customs, which can provide significant references for the design and reformation of modern new-type vernacular dwellings. 展开更多

A method that combines category-based and keyword-based concepts for a better information retrieval system is introduced. To improve document clustering, a document similarity measure based on cosine vector and keywords frequency in documents is proposed, but also with an input ontology. The ontology is domain specific and includes a list of keywords organized by degree of importance to the categories of the ontology, and by means of semantic knowledge, the ontology can improve the effects of document similarity measure and feedback of information retrieval systems. Two approaches to evaluating the performance of this similarity measure and the comparison with standard cosine vector similarity measure are also described. 展开更多

This paper presents a new approach to determining whether an interested personal name across doeuments refers to the same entity. Firstly,three vectors for each text are formed: the personal name Boolean vectors denoting whether a personal name occurs the text the biographical word Boolean vector representing title, occupation and so forth, and the feature vector with real values. Then, by combining a heuristic strategy based on Boolean vectors with an agglomeratie clustering algorithm based on feature vectors, it seeks to resolve multi-document personal name coreference. Experimental results show that this approach achieves a good performance by testing on "Wang Gang" corpus. 展开更多

Accompanying rapid developments in hepatic surgery,the number of surgeries and identifications of histological types of primary hepatic space-occupying lesions (PHSOLs) have increased dramatically.This has led to many changes in the surgicopathological spectrum of PHSOLs,and has contributed to a theoretical basis for modern hepatic surgery and oncological pathology.Between 1982 and 2009 at the Eastern Hepatobiliary Surgery Hospital (EHBH) in Shanghai,31 901 patients underwent surgery and were diagnosed as having a PHSOL.In this paper,we present an analysis of the PHSOL cases at the EHBH for this time period,along with results from a systematic literature review.We describe a surgicopathological spectrum comprising more than 100 types of PHSOLs that can be stratified into three types:tumor-like,benign,and malignant.We also stratified the PHSOLs into six subtypes derived from hepatocytes;cholangiocytes;vascular,lymphoid and hemopoietic tissues;muscular,fibrous and adipose tissues;neural and neuroendocrine tissues;and miscellaneous tissues.The present study provides a new classification system that can be used as a current reference for clinicians and pathologists to make correct diagnoses and differential diagnoses among various PHSOLs. 展开更多

AIM:To analyze the experience within our hospital and to review the literature so as to establish the best means of diagnosis of abdominal tuberculosis. METHODS:The records of 11 patients (4 males,7 females, mean age 39 years,range 18-65 years) diagnosed with abdominal tuberculosis in Harran University Hospital between January 1996 and October 2003 were analyzed retrospectively and the literature was reviewed. RESULTS:Ascites was present in all cases.Other common findings were weight loss (81%),weakness (81%),abdominal mass (72%),abdominal pain (72%),abdominal distension (63%),anorexia (45%) and night sweat (36%).The average hemoglobin was 8.2 g/dL and the average FAR was 50 mm/h (range 30-125).Elevated levels of cancer antigen CA-125 were determined in four patients.Abdominal ultrasound showed abnormalities in all cases:ascites in all,tuboovarian mass in five,omental thickening in 3,and enlarged lymph nodes (mesenteric,para-aortic) in 2.CT scans showed ascites in all,pelvic mass in 5,retroperitoneal lymphadenopathy in 4,mesenteric stranding in 4,omental stranding in 3, bowel wall thickening in 2 and mesenteric lymphadenopathy in 2.Only one patient had a chest radiograph suggestive of a new TB lesion.Two had a positive family history of pulmonary TB.None had acid-fast bacilli (AFB) in the sputum and the tuberculin test was positive in only two.Laparotomy was performed in 6 cases,laparoscopy in 4 and ultrasound- guided fine needle aspiration in 2.In those patients subjected to operation,the findings were multiple diffuse involvement of the visceral and parietal peritoneum,white ‘miliary nodules’or plaques,enlarged lymph nodes,ascites, ‘violin string’fibrinous strands,and omental thickening. Biopsy specimens showed granulomas,while ascitic fluid showed numerous lymphocytes.Both were negative for acid-fast bacilli by staining.PCR of ascitic fluid was positive for Mycobactenum tuberculosis ( M.tuberculosis) in all cases. CONCLUSION:Abdominal TB should be considered in all cases with ascites.Our experience suggests that PCR of ascitic fluid obtained by ultrasound-guided fine needle aspiration is a reliable method for its diagnosis and should at least be attempted before surgical intervention. 展开更多

The causative species was determined to be Enteromorpha prolifera (Ulva prolifera O. F. Miiller), a familiar green macroalga along the coastline of China. Rapid accumulation of a large biomass of floating U. prolifera prompted research on different aspects of this species. In this study, we constructed a nonnormalized cDNA library from the thalli of U. prolifera and acquired 10072 high-quality expressed sequence tags (ESTs). These ESTs were assembled into 3 519 nonredundant gene groups, including 1 446 clusters and 2 073 singletons. After annotation with the nr database, a large number of genes were found to be related with chloroplast and ribosomal protein, GO functional classification showed 1 418 ESTs participated in photosynthesis and 1 359 ESTs were responsible for the generation of precursor metabolites and energy. In addition, rather comprehensive carbon fixation pathways were found in U. prolifera using KEGG. Some stress-related and signal transduction-related genes were also found in this study. All the evidences displayed that U. prolifera had substance and energy foundation for the intense photosynthesis and the rapid proliferation. Phylogenetic analysis of cytochrome c oxidase subunit I revealed that this green-tide causative species is most closely affiliated to Pseudendoclonium akinetum (Ulvophyceae). 展开更多

Water deficits observed in many regions of the world make it necessary to implement measures intended to improve this situation. Poland is one of the countries with the poorest water resources in Europe due to its natural conditions and human impact. As a result of land reclamation carried out over decades, many elements of its hydrographic system have been changed, and some of them, like lakes, have disappeared altogether. In the days of the socio-economic transformation and more frequent extreme events, what seems worth considering is the renaturalisation of non-existing lakes, an idea presented in this paper on a selected example. 展开更多

Fire is quite a common natural phenomenon closely related to forest hydrology in forest ecosystem. The influence of fire on water is indirectly manifested in that the post fire changes of vegetation, ground cover, soil and environment affect water cycle, water quality and aquatic lives. The effect varies depending upon fire severity and frequency. Light wildland fires or prescribed burnings do not affect hydrology regime significantly but frequent burnings or intense fires can cause changes in hydrology regime similar to that caused clear cutting. 展开更多

Integrated multi-trophic aquaculture (IMTA) has been proposed as a concept that combines the cultivation of fed aquaculture species (e.g., finfish/shrimp) with extractive aquaculture species (e.g., shellfish/seaweed). In seaweed-based integrated aquaculture, seaweeds have the capacity to reduce the environmental impact of nitrogen-rich effluents on coastal ecosystems. Thus, selection of optimal species for such aquaculture is of great importance. The present study aimed to develop a seaweed species-selection index for selecting suitable species in seaweed-based integrated aquaculture system. The index was synthesized using available literature-based information, reference data, and physiological seaweed experiments to identify and prioritize the desired species. Undaria pinnatifida, Porphyra yezoensis and Ulva compressa scored the highest according to a seaweed-based integrated aquaculture suitability index (SASI). Seaweed species with the highest scores were adjudged to fit the integrated aquaculture systems. Despite the application of this model limited by local aquaculture environment, it is considered to be a useful tool for selecting seaweed species in IMTA. 展开更多

The objectives of this study were to analyze the biodiversity of the Traditional Gudeuljang Irrigated Rice Terraces in Cheongsando, South Korea's representative GIAHS(Globally Important Agricultural Heritage System) site, with reference to position and land-use features, and to develop a plan to promote agricultural biodiversity in the region. We confirmed approximately 54,000 m2 of Gudeuljang paddy fields by an on-site survey. Of the Traditional Gudeuljang Irrigated Rice Terraces confirmed by onsite inspection, our survey showed that approximately 24,000 m2 are currently being used as paddy fields, approximately 15,000 m2 are being used as dry fields, and approximately 14,000 m2 are fallow. In terms of other non-agricultural land use, there was grassland, including graveyards; artificial arboreal land, such as orchards, rivers and wetlands, and man-made facilities, such as roads and residences. We also confirmed that the Traditional Gudeuljang Irrigated Rice Terraces had higher plant species diversity than conventional terraced rice paddies, and there was a difference in life form characteristics between the two types. Although the superficial topsoil structure is thesame for the Traditional Gudeuljang Irrigated Rice Terraces(TGIRTs) and conventional terraced rice paddies, it is thought that the differences in the subsurface structure of the TGIRTs contribute greatly to species and habitat diversity. However, the TGIRTs in Cheongsando are facing degeneration, due to damage and reduction in agricultural activity. The main cause is the reduction in the number of farming households due to an aging population in Cheongsando. In order to address this problem, we proposed a management plan, related to fallow paddy fields in South Korea, to initiate voluntary activities in the TGIRTs. 展开更多
