Soil properties related to land-use systems in oases of Sangong river watershed,Xinjiang

Understanding the effect of human activities on the soil environment is fundamental to understanding global change and sustainable development.In the process of transformation of tropical rain forests and semiarid grasslands to farmlands,land degradation usually occurs.But the transformation of arid desert landscape to oasis is found to have quite different consequences.Taking an alluvial plain oasis in the north piedmont of the Tianshan Mountains as a case study,we investigate oasis soil properties related to different land-use systems during the transformation of arid desert to oases.Selected land-use systems consisted of an annual crop field less than 3 years old,annual crop field 3-6 years old,annual crop field more than 6 years old,perennial crop field less than 4 years old,perennial crop field of 4-6 years old,perennial crop field more than 6 years old,abandoned farmland more than 3 years old,woodland field more than 6 years old,ecological forestation field,natural shrubbery field,desert grass land,and saline or alkaline field.Different land-use systems affect significantly the distribution of sand,silt and clay.Sand content in oasis soil tends to decrease with cultivation years but silt and clay contents tend to be increased in the oasis soils.Soil fertility is higher in the land-use systems under strong human disturbance than under weak human disturbance.Oasis soil nutrients also tend to increase with cultivation years.Soils have a significantly lower salinity in the land-use systems under strong human disturbance than under weak human disturbance.Soil organic matter and nutrients of the annual and perennial crop systems in the oasis tend to increase with cultivation time with the oasis soil acting as a carbon sink.These results show that soils are not degraded and the soil quality is gradually improved under rational land use and scientific management patterns,including uniform exploitation of land resources,effective irrigation systems,sound drainage systems,balanced fertilizer application,crushed straw return to soil and transformation of annual crop fields to perennial ones.
Dust storms evolution in Taklimakan Desert and its correlation with climatic parameters

Based on the sand dust storms data and climatic data in 12 meteorological stations around sand dust storm originating areas of the Taklimakan Desert,we analyzed the trends of the number of dust storm days from 1960 to 2005 as well as their correlations with temperature,precipitation,wind speed and the number of days with mean wind speed ≥ 5 m/s.The results show that the frequency of dust storm events in the Taklimakan region decreased with the elapse of time.Except Ruoqiang and Minfeng,in the other 10 meteorological stations,the frequency of dust storm events reduces,and in 4 meteorological stations of Kuqa,Korla,Kalpin and Hotan,the frequency of dust storm events distinctly decreases.The temperature has an increasing trend,while the average wind speed and the number of days with mean wind speed ≥ 5 m/s have decreasing trends.The correlation analysis between the number of days of dust storms and climatic parameters demonstrates that wind speed and the number of days with mean wind speed ≥ 5 m/s have strong positive correlation with the number of days of dust storms,with the correlations coefficients being 0.743 and 0.720(p<0.01),respectively,which indicates that strong wind is the direct factor resulting in sand dust storms.Whereas precipitation has significant negative correlation with the number of days of dust storms(p<0.01),and the prior annual precipitation has also negative correlation,which indicates that the prior precipitation restrains the occurrence of sand dust storms,but this restraining action is weaker than the same year's precipitation.Temperature has negative correlation with the number of dust storm days,with a correlations coefficient of-0.433(p<0.01),which means that temperature change also has impacts on the occurrence of dust storm events in the Taklimakan region.
Mercury concentration in hair samples from Chinese people in coastal cities

This investigation was made to estimate current normal concentrations of total mercury in the hair of Chinese coastal people. Hair samples were collected from 659 healthy inhabitants in the areas along the coast and the rivers (such as Shanghai, Ningbo, Dalian, Xiamen, and Zhoushan) of China from Feb. 2005 to June 2006. Total mercury concentrations in the samples were analyzed by the cold vapor atomic adsorption spectrometry method (CVAAS). The results showed the geometric mean concentration of total mercury in the hair of the total population (N = 659) was 0.83 g/g, and the geometric mean of the concentrations of total mercury in the hair of the male (0.94 g/g, 338 inhabitants with an average age of 35.2, age 2–93) was higher than that of the female (0.72 g/g, 321 inhabitants with an average age of 39.1, age 1–90). In both the male and female, the mean concentrations of total mercury in hair increased with age, and then gradually decreased. There was a significant correlation between the total hair mercury and the place of residence (p < 0.01), and total hair mercury was the highest in volunteers who lived in Zhoushan. Over half of all sample concentrations were below the USEPA-recommended 1 g/g. In Zhoushan (males, 2.44 g/g; females, 1.94 g/g) and Ningbo (males, 1.06 g/g; females, 1.02 g/g), it exceeded the recommended level. Very little females (0.3%) of reproductive age showed hair mercury levels close to 10 g/g. It was thus concluded that fish consumption was a major current route for mercury exposure in China.
Degradation and mineralization of 2-chloro-, 3-chloro- and 4-chlorobiphenyl by a newly characterized natural bacterial strain isolated from an electrical transformer fluid-contaminated soil

A bacterium classified as Achromobacter xylosoxidans strain IR08 by phenotypic typing coupled with 16S rRNA gene analysis was isolated from a soil contaminated with electrical transformer ?uid for over sixty years using Aroclor 1221 as an enrichment substrate. The substrate utilization profiles revealed that IR08 could grow on all three monochlorobiphenyls (CBs), 2,4’- and 4,4’-dichlorobiphenyl as well as 2-chlorobenzoate (2-CBA), 3-CBA, 4-CBA, and 2,3-dichlorobenzoate. Unusually, growth was poorly sustained on biphenyl and benzoate. In growth experiments, IR08 degraded all CBs (0.27 mmol/L) in less than 96 h with concomitant stoichiometric release of inorganic chloride and growth yields were 2–3 times higher than those observed on biphenyl. In contrast to most of the chlorobiphenyl- degrading strains described in the literature, which are reported to form CBA, no metabolite was identified in the culture broth by HPLC analysis. When co-incubated with respective CBs and biphenyl, strain IR08 preferentially utilized the chlorinated analogues in less than 96 h while it took another 264 h before 90% of the initially supplied biphenyl could be degraded. The promotion of co- metabolic transformation of halogenated substrates by the inclusion of their non-halogenated derivatives may not therefore, result in universal benefits.
Solubility and sorption of petroleum hydrocarbons in water and cosolvent systems

The solubility and sorption of oil by uncontaminated clay loam and silt loam soils were studied from water and cosolvent/water solutions using batch techniques. The data obtained from the dissolution and sorption experiments were used to evaluate the applicability of the cosolvent theory to oil as a complex mixture. Aqueous solubility and soil-water distribution coeff_cients (K_(d,w), L/kg) were estimated by extrapolating from cosolvent data, with a log-linear cosolvency model, to the volume fraction of cosolvent (f_c) 0, and were compared with direct aqueous measurements. The extrapolated water solubility was 3.16 mg/L, in good agreement with the directly measured value of 3.83 mg/L. Extrapolated values of K_(d,w) for the two soils were close to each other but consistently higher than the values from direct aqueous measurements, because of the presence of dissolved organic carbon (DOC). The partition coe?cient (K_(DOC)) between the DOC and the freely dissolved phase and the OC-normalized sorption coeff_cient (K_(OC)) were determined. The average values of logK_(DOC) and logK_(OC) were estimated as 4.34 and 3.32, respectively, giving insight into the possibility of oil becoming mobilized and/or of the soil being remedied. This study revealed that the cosolvency model can be applied to a broader range of hydrophobic organic chemicals (HOCs) than has been previously thought. The results aided in a reliable determination of water solubility and sorption coeff_cients and provide information about the fate of oil in solvent-contaminated environment.
Synthesis,Characterization,and DNA Binding Properties of Dinuclear Copper(Ⅱ) Complex [Cu_2(TATP)_2(L-Leu)_2(ClO_4)_2]_2·2H_2O

A dinuclear copper(Ⅱ) complex [Cu_2(TATP)_2(L-Leu)_2(ClO_4)_2]_2·2H_2O was synthesized and characterized,where,TATP=1,4,8,9-tetraazatriphenylene,and L-Leu=L-leucinate. The complex was crystallized in the triclinic space group P1,with two independent molecules in a unit cell. Two Cu(Ⅱ) ions in each complex [Cu_2(TATP)_2(L-Leu)_2(ClO_4)_2] molecule were found to be in different coordination geometries,i.e.,Cu2 or Cu4 of a distorted square-pyramidal geometry coordinated with two nitrogens of TATP,the amino nitrogen and one carboxylate oxygen of L-Leu and one oxygen of perchlorate,and Cu1 or Cu3 with an octahedral geometry coordinated with the above stated similar coordinated atoms,and another carboxylate oxygen of L-Leu coordinating to Cu2 or Cu4. The complex can interact with CT-DNA by an intercalative mode and cleave pBR322 DNA in the presence of ascorbate.
Dynamical analysis of mesoscale eddy-induced ocean internal waves using linear theories

This study aims to explore generation mechanisms of the ocean internal wave using the dynamical analysis methods based on linear theories.Historical cruise measurements and recent synthetic aperture radar(SAR)observations of mesoscale eddies with diameter of several tens of kilometers to hundreds of kilometers show that the internal wave packets with wavelength of hundreds of meters to kilometer exist inside the mesoscale eddies.This coexistence phenomenon and inherent links between the two different scale processes are revealed in the solutions of governing equations and boundary conditions for the internal wave disturbance with a horizontally slowly variable amplitude in a cylindrical coordinate system.The theoretical solutions indicate that the instability of eddy current field provides the dynamical mechanism to internal wave generation.The derived dispersion relation indicates that the internal wave propagation is modified by the eddy current field structure.The energy equation of the internal waves clearly shows the internal wave energy increment comes from the eddy.The theoretical models are used to explain the observation of the mesoscale eddy-induced internal waves off the Norwegian coast.The two-dimensional waveform solution of the anticyclonic eddy-induced internal wave packet appears as ring-shaped curves,which contains the typical features of eddy stream lines.The comparison of theoretical solutions to the structure of the internal wave packets on SAR image shows a good agreement on the major features.
Barrier and compensation layers in the East China Sea

Climatology of the isothermal layer depth(ILD)and the mixed layer depth(MLD)has been produced from in-situ temperature-salinity observations in the East China Sea(ECS)since 1925.The methods applied on the global are used to compute the ILD and the MLD in the ECS with a temperature criterion ΔT=0.8 ℃ for the ILD,and a density criterion with a threshold Δσθ corresponding to fixed ΔT=0.8 ℃ for the MLD,respectively.With the derived climatology ILD and MLD,the monthly variations of the barrier layer(BL)and the compensation layer(CL)in the ECS are analyzed.The BL mainly exists in the shallow water region of the ECS during April-June with thickness larger than 15 m.From December to next March,the area along the shelf break from northeast of Taiwan Island to the northeast ECS is characterized by the CL.Two kinds of main temperature-salinity structures of the CL in this area are given.
Differential attraction of parasitoids in relation to specificity of kairomones from herbivores and their by-products

Infochemicals are used by foraging parasitoids in the host selection process from habitat preference until host recognition. Kairomones from the herbivore host plays a vital role in the attraction of parasitoids, particularly in the micro-habitat. Parasitoids are specifically attracted to their respective herbivore species even when different herbivores are present on the same plant. Chemicals emitted from different stages of host (eggs, larvae, pupae, adult), host by-products (e.g., frass, exuviae, mandibular gland secretions, defense secretions etc.), or intra-specific infochemicals (pheromones) can be main signals for the parasitoids. Parasitoids can differentiate between host and non-host, between different hosts and host stages by perceiving specific volatile and contact kairomones from the host itself, host along with its by-product, by-products alone or intra-specific infochemicals; of which frass (by-product) and intra-specific infochemicals are the most reported ones. Adult and larval parasitoids have been reported to be attracted to kairomones of their target stage or byproduct of their host. Pupal parasitoids have been found to utilize kairomones from the preceding host stage while egg parasitoids are known to exploit a variety of host infochemicals, for example, either from eggs themselves or other non-target host stages, especially adults and adult-related by-products. The kairomonal chemicals identified so far include various groups, but mainly hydrocarbons. A high degree of host specificity and host acceptance is important for the parasitoids as any mistake may result in the loss of fitness.
Arabidopsis Kinesins HINKEL and TETRASPORE Act Redundantly to Control Cell Plate Expansion during Cytokinesis in the Male Gametophyte

Asymmetric cell division at pollen mitosis I (PMI) is required to specify the differential fate of the daughter vegetative and generative cells. Cytokinesis at PMI displays specialized features, and it has been suggested that there might be distinct molecular pathways underpinning different modes of cytokinesis in plants. Activation of the NACK–PQR MAP kinase signaling pathway, which is essential for somatic cell cytokinesis in tobacco, depends upon the NACK1 and NACK2 kinesin-related proteins. Their Arabidopsis orthologs, HINKEL (HIK) and TETRASPORE (TES), were reported to be essential for cytokinesis in somatic cells and in microsporocytes, respectively. More recently, HIK and TES were shown to have a functionally redundant role in female gametophytic cytokinesis. We report here that HIK and TES are co-expressed in microspores and developing pollen, and, through analysis of microspore and pollen development in double heterozygote mutants, the occurrence of cell plate expansion defects during cytokinesis at PMI. The data demonstrate a functionally redundant role for HIK and TES in cell plate expansion during male gametophytic cytokinesis, extending the concept that different modes of cytokinesis are executed by a common signaling pathway, but reinforcing the individuality of gametophytic cytokinesis in its requirement for either TES or HIK.
High throughput route selection in multi-rate wireless mesh networks

Most existing Ad-hoc routing protocols use the shortest path algorithm with a hop count metric to select paths. It is appropriate in single-rate wireless networks, but has a tendency to select paths containing long-distance links that have low data rates and reduced reliability in multi-rate networks. This article introduces a high throughput routing algorithm utilizing the multi-rate capability and some mesh characteristics in wireless fidelity (WiFi) mesh networks. It uses the medium access control (MAC) transmission time as the routing metric, which is estimated by the information passed up from the physical layer. When the proposed algorithm is adopted, the Ad-hoc on-demand distance vector (AODV) routing can be improved as high throughput AODV (HT-AODV). Simulation results show that HT-AODV is capable of establishing a route that has high data-rate, short end-to-end delay and great network throughput.

腔镜甲状腺手术是一种治疗甲状腺疾病的外科新方法,有显著的美容效果.随着腔镜外科医生的经验积累和手术器械的不断改进(如超声刀的应用),腔镜甲状腺手术的适应证逐步扩大[1-2].我们对2006年1月至2007年6月本院收治的4例因接受腔镜手术治疗导致再手术的甲状腺癌患者的临床资料进行了回顾性分析,旨在探讨腔镜甲状腺手术用于甲状腺癌治疗的可行性.
泌尿组织工程学的进展

20世纪末期组织工程学为组织或器官的修复与重建带来了全新的概念.从最初的材料修复到现在的干细胞和克隆技术的运用,组织工程技术在泌尿外科学的研究已经从实验室和动物模型阶段向人体临床应用发展,新技术、新方法、新的理念也伴随着基础研究和临床实践不断涌现.
妊娠合并肺动脉高压的处理

随着孕期保健的开展及产科质量的提高,孕产妇死亡率逐年下降,但由于妊娠合并心脏病患者的增多,而导致的孕产妇死亡率明显增加,尤其肺动脉高压(PAH)患者妊娠猝死的危险性更大,孕产妇死亡率与肺动脉压力的高低密切相关,重度肺动脉高压者死亡率高达50%以上[1].因此妊娠合并肺动脉高压已引起产科学者的高度重视.
脑深部刺激治疗帕金森病的研究进展

帕金森病是一种慢性退行性运动系统疾病,其主要的病理变化为黑质致密部多巴胺能神经元变性,纹状体内多巴胺大量减少.丘脑底核（subthalamicucleus, STN）脑深部电刺激（deep brain stimulation, DBS）是目前治疗中晚期帕金森病一种很好方法，具有良好的疗效，延长了运动障碍缓解期，手术安全性高，术后并发症较少，患者耐受性较好，并且一部分患者术后可逐步减少药物剂量。
如何诊断儿童尿路感染?

尿路感染(UTI)是儿科常见病,若置之不理就会引发肾功能障碍.由此可见,准确诊断尿路感染至关重要.为了明确不同症状和体征在准确诊断婴幼儿尿路感染中的作用,来自匹兹堡大学医学院儿科系的Nader Shaikh及其同事对MEDLINE及EMBASE数据库中发表于1966年至2007年的相关文献进行了检索,此外还审阅了所有满足入选标准的文章的参考文献,1篇既往发表的系统综述以及3本临床技能教材,另外还与2名该领域的专家交换意见,最后共找到6988篇可能相关的文章,其中仅有12篇文章满足所有入选标准.
加强探讨脂毒性的多脏器损害

脂毒性是糖尿病发病的重要原因之一.我们知道当营养过量时,随着脂肪细胞的增大,脂肪细胞出现功能异常,对胰岛素抗脂解作用减弱,导致游离脂肪酸(FFA)外溢增多.
瑞替普酶溶栓治疗急性心肌梗死患者的疗效观察

急性心肌梗死(AMI)治疗的主要策略之一是尽早、完全地开通梗死相关动脉(IRA)的前向血流,恢复组织水平的再灌注.对于症状发作12 h内的AMI患者,进行溶栓治疗具有明显的疗效.第3代溶栓药物瑞替普酶(r-PA,商品名派通欣)是一种新型重组组织型纤溶酶原激活剂(rt-PA),静脉推注给药使用方便.现对我院急诊科应用r-PA治疗AMI患者的疗效进行总结,报告如下.
