The emergence of nucleic acid-based molecular techniques has significantly enhanced laboratory diagnosis and monitoring of atypical pneumonia. These techniques have not only provided rapid and sensitive detection of fastidious microbial organisms but have also played critical roles in identifying and characterizing emerging patho- gens that cause atypical pneumonia. Other benefits that molecular techniques can bring to the field include organism differentiation, quantitation, typing, and antibiotic resistance profiles. Gradually becoming standardized and widely available, the future will see some promising molecular methods become a mainstay in clinical laboratories for recognition and diagnosis of atypical pneumonia pathogens.

Accurate thermal simulation is the key in the simulation approach to defining the unique microstructure and properties of the HAZ regions. Simulation enables an expansion of the volume of material char- acteristic of each H4Z region to a sufficient size for property *** combined influence of heat input,preheat temperature, plate thickness, and widing process on HAZ microstructure and properties relics on the accurate simulation of thermal cycles corresponding to different peak temperatures using an HAZ simulator like the *** computer programs have been developed to predict thermal excursions in various HAZ regions during welding. Some were developed based simply on the thermal propertics of a material;whereas, others were generated on the basis of actual experimental data.A suitable HAZ thermal simulation program must be ons that can authntically duplicate an ac- tual thermal cycle experienced during welding within reasonable limies. Therefore, the similarities and differences among the HAZ thermal cycles predicted by various methodologies should be fully under- stood. A total of sts thermal cycle prediction methodologies were compared in this evaluation.

The western part of China borders on South and Southeast Asia. Of the numerous well known international rivers sharing with the two regions, the Lancang Mekong River has been most extensively studied in the world for its important strategic position, rich resources, prosperous potential market as well as considerable opportunities for investment and development. The sustainable multipurpose development in this area has increasingly become the focus of international regional cooperation, and great attention has been paid to this area by the international society. Up to now, at least 10 major actions in the international regional cooperation are expected in this area. This paper intends, at the angle of geography and with the overall target of promoting the sustainable development in the basin through international cooperations, to study the international position, the potential and the prospects for development of the Lancang Mekong River, to analyze the main problems in this international cooperation, to propose targets and prospects for such cooperation, and to indicate the way for geographers to participate in such research.

miRNAs are a class of small RNA molecules with regulatory function, and play an important role in tumor development and progression. It has been demonstrated that tumor-derived miRNAs exist in the circulating nucleic acids of cancer patients. This phenomenon implies that detection of the circulating miRNA may be an effective method for non-invasive diagnosis of cancer. In this review, we summarize the applications of the circulating miRNA as biomarkers in cancer diagnosis, as well as the latest research progress in this area.

大港孔店油田油藏特征、流体和微生物性质分析结果表明,属于高温生态环境,地层水矿化度较低,氮、磷浓度低,而且缺乏电子受体,主要的有机物来源是油气。油田采用经过除油处理的油藏产出水回注方式开发,油层中存在的微生物类型主要是厌氧嗜热菌,包括发酵菌(102个/mL^105个/mL),产甲烷菌(103个/mL);好氧菌主要存在于注水井周围。硫酸盐还原菌(SRB)还原速率0.002μgS2-/(L·d)~18.9μgS2-/(L·d),产甲烷菌产甲烷速率0.012μgCH4/(L·d)~16.2μgCH4/(L·d)。好氧菌能够氧化油形成生物质,部分氧化产物为挥发性脂肪酸和表面活性剂。产甲烷菌在油氧化菌液体培养基中产生CH4,CO2为好氧微生物和厌氧微生物的共同代谢产物。这些产物具有提高原油流动性的作用。用示踪剂研究了注入水渗流方向。通过综合分析,油藏微生物具有较大的潜力,基于激活油层菌的提高采收率方法在该油田是可行的。
