| 1 | Ammonia-oxidizing archaea and bacteria are structured by geography in biological soil crusts across North American arid lands显示文摘Introduction:Biological soil crusts(BSCs)can dominate surface cover in dry lands worldwide,playing an integral role in arid land biogeochemistry,particularly in N fertilization through fixation and cycling.Nitrification is a characteristic and universal N transformation in BSCs that becomes important for the export of N beyond the microscopic bounds of the crust itself.The contribution of ammonia-oxidizing bacteria(AOB)in BSCs has been shown,but the role and extent of the recently discovered ammonia-oxidizing archaea(AOA)have not.Methods:We sampled various types of crusts in four desert regions across the western United States and characterized the composition and size of ammonia-oxidizing communities using clone libraries and quantitative PCR targeting the amoA gene,which codes for the ammonia monooxygenase enzyme,universally present in ammonia-oxidizing microbes.Results:All archaeal amoA sequences retrieved from BSCs belonged to the Thaumarchaeota(Nitrososphaera associated Group I.1b).Sequences from the Sonoran Desert,Colorado Plateau,and Great Basin were indistinguishable from each other but distinct from those of the Chihuahuan Desert.Based on amoA gene abundances,archaeal and bacterial ammonia oxidizers were ubiquitous in our survey,but the ratios of archaeal to bacterial ammonia oxidizers shifted from bacterially dominated in northern,cooler deserts to archaeally dominated in southern,warmer deserts.Conclusions:Archaea are shown to be potentially important biogeochemical agents of biological soil crust N cycling.Conditions associated with different types of BSCs and biogeographical factors reveal a niche differentiation between AOA and AOB,possibly driven by temperature. | Yevgeniy Marusenko Scott T Bates Ian Anderson Shannon L Johnson Tanya Soule Ferran Garcia-Pichel | 2013 | Ecological Processes2013，2，1： | 4 |
| 2 | 强化降压对高血压患者左心室肥厚的影响显示文摘目前尚不清楚超出推荐值的强化降压是否更能降低高血压患者的左心室肥厚(left ventricular hypertrophy,LVH)发生风险,以及LVH风险降低能否解释强化降压的益处。Soliman等纳入收缩压干预试验(systolic blood pressure intervention,SPRINT)中患有高血压但无糖尿病的8164例受试者(平均年龄67.9岁,女性35.3%,31.2%为非洲裔), | 刘莉 叶鹏 Soliman EZ Ambrosius WT Cushman WC Zhang ZM Bates JT Neyra JA Carson TY Tamariz L Ghazi L Cho ME Shapiro BP He J Fine LJ Lewis CE SPRINT Research Study Group | 2017 | 中华高血压杂志2017，25，6： | 2 |
