BACKGROUND The purpose of this study was to perform a dosimetric comparison between proton beam therapy (PBT) and photon radiation therapy in patients with locally advanced esophageal squamous cell carcinoma (ESCC) who were treated with PBT in our institution. In addition, we evaluated the correlation between toxicities and dosimetric parameters, especially the doses to normal lung or heart tis...

ABSTRACT- Desert truffles are hypogeous ascomyceteous ectomycorrhizal fungi, occurring in arid and semi-arid ecosystems. A PCR-based method was developed for the identification of 3 major desert truffles of Iran: Terfezia claveryi, Tirmania pinoyi and Tirmania nivea based on internal transcribed spacers of rDNA. Two specific PCR primers were designed for T. claveryi, 4 for T. pinoyi, and 2 for ...

Introduction Determining the area-at-risk (AAR) in acute coronary syndromes (ACS) after Percutaneous Coronary Intervention (PCI) is remaining a challenge and is crucial to estimate the myocardial salvage and especially the AAR/infarct-size ratio. Depicting the AAR accurately maximizes then ability to test acute imaging paradigms. In addition, evaluating the occurrence of early hemorrhagic trans...

The roots of nearly all land plants form mycorrhizal symbioses with specialized soil fungi. The mycorrhizal fungi serve as extensions of plant roots, taking up nutrients and water and transferring them to the roots. In return, the mycorrhizal fungi receive their primary energy source in the form of simple sugars from plant photosynthates translocated to the roots. Sequoiadendron giganteum forms...

土壤微生物是表征土壤质量的敏感指标，采用Illumina HiSep技术分析不同覆盖方式对半湿润易旱区农田土壤微生物群落结构及多样性的影响，以期从微生物的角度评价农田不同覆盖措施对土壤质量的影响。设3种覆盖模式：平作塑料薄膜覆盖（P）、平作秸秆覆盖（S）和垄膜沟播覆盖（R），以平作不覆盖为对照（CK），研究不同覆盖模式下土壤微生物群落变化，分析各土壤理化因子与微生物群落之间的关系。研究结果表明各覆盖处理显著改变了土壤微生物的群落结构和多样性。所有土壤样品中，细菌群落的优势菌门是变形菌门（Proteobacteria）、酸杆菌门（Acidobacteria）、放线菌门（Actinobacteria），丰度分别为29.69%、28.28%和20.76%，CK处理下较高的土壤pH和低NO3-N含量抑制了土壤中酸杆菌门（Acidobacteria）的生长繁殖，而放线菌门...

Madagascar is known for its high diversity and endemism of fauna flora. Fungi, however, have been largely overlooked in evolution studies on the island, whether fungi exhibit same patterns as animals plants has yet to be further examined. We collected fungal sporocarps ectomycorrhizal (EcM) roots during three opportunistic surveys five forests generated a dataset Internal Transcribed Spacer (IT...
