  5. The phosphorus speciations in the sediments up- and down-stream of cascade dams along the middle Lancang River.

    Chemosphere 120:653 (2015) PMID 25462310

    We detected the longitudinal variability of phosphorus speciations and its relation to metals and grain size distribution of sediments in three cascade canyon reservoirs (Xiaowan, Manwan and Dachaoshan) along Lancang River, China. Five phosphorus speciations including loosely bound P (ex-P), red...

    • We investigated the longitudinal variation of P speciations in sediments. • The maximum releasing risk level of BAP was found in the lowest reservoir. ...
  8. Seasonal changes of CO2, CH4 and N2O fluxes in different types of alpine grassland in the Qinghai-Tibetan Plateau of China

    Soil Biology and Biochemistry 80:306 (2015)

    Grassland degradation and grassland use type changes are associated with dynamics in soil properties and biogeochemical cycling, with implications for carbon and nitrogen cycling and trace gas fluxes. To examine the influence of grassland degradation and grassland use type changes on g...

  10. Radiotherapy for asymptomatic brain metastasis in epidermal growth factor receptor mutant non-small cell lung cancer without prior tyrosine kinase inhibitors treatment: a retrospective clinical study.

    Radiation Oncology 10:118 (2015) PMID 26014133 PMCID PMC4490723

    Non-small cell lung cancer (NSCLC) with brain metastasis (BM) harboring an epidermal growth factor receptor (EGFR) mutation shows good response to tyrosine kinase inhibitors (TKIs). This study is to assess the appropriate timing of brain radiotherapy (RT) for asymptomatic BM in EGFR mutant NSCLC...
  11. An international contrast of rates of placental abruption: an age-period-cohort analysis.

    PLoS ONE 10(5):e0125246 (2015) PMID 26018653 PMCID PMC4446321

    Although rare, placental abruption is implicated in disproportionately high rates of perinatal morbidity and mortality. Understanding geographic and temporal variations may provide insights into possible amenable factors of abruption. We examined abruption frequencies by maternal age, delivery y...
  12. Effects of short-term and long-term warming on soil nutrients, microbial biomass and enzyme activities in an alpine meadow on the Qinghai-Tibet Plateau of China

    Soil Biology and Biochemistry 76:140 (2014)

    Two open-top chambers (OTCs) experiments were conducted to assess the impacts of 2-year and 10-year warming on soil biochemistry in the alpine meadow on the Qinghai-Tibet Plateau (QTP) of China. The soil warming at 0.8–1.1 °C above the control in the two experiments did not significant...
