Bromocriptine-induced removal of endoplasmic membranes from prolactinoma cells

Summary Adenomatous prolactin cells lose 39% of their cytoplasm volume within 7 days after the beginning of bromocriptine treatment. A simultaneous reduction of the rough-surfaced endoplasmic reticulum and the Golgi apparatus occurs. Their membranes are removed by rapid transport along the secretory pathway to the cell surface and to lysosomal destruction.We thank Prof. E. del Pozo, Sandoz Ltd, Basle, for the generous gift of injectable bromocriptine, Prof. E.R. Weibel, Dept. of Anatomy, University of Bern, for his technical advice, Dr U. Helfenstein, Institute of Biostatistics, University of Zürich, for his help in the statistical evaluation of the results and the EMDO-Foundation, Zürich, for financial support.     

Energy flow and community structure in freshwater ecosystems

The goal of this article is twofold: 1) It aims at providing an overview on some major results obtained from energy flow studies in individuals, populations, and communities, and 2) it will also focus on major mechanisms explaining community structures. The basis for any biological community to survive and establish a certain population density is on the one hand energy fixation by primary producers together with adequate nutrient supply and the transfer of energy between trophic levels (bottom-up effect). On the other hand, predator pressures may strongly control prey population densities one or more trophic levels below (top-down effect). Other interpopulation effects include competition, chemical interactions and evolutionary genetic processes, which further interact and result in the specific structuring of any community with respect to species composition and population sizes.     

秦淮河流域典型排涝泵站前池水质与降雨特征响应关系

为分析排涝泵站前池水质与降雨特征的响应关系,对南京市城区秦淮河沿线2个排涝泵站前池水质以及降水量开展高频在线自动监测,结合回归树方法分析了不同降雨强度、前期干旱时间条件下排涝泵站前池水质变化规律,探讨了不同类型排涝泵站前池水质的主要影响因素。结果表明:晴雨天均有生活污水汇入的A泵站前池氨氮质量浓度在大雨强下降低,中雨强下先升高后降低,小雨强下平缓上升,A泵站前池污染物质量浓度主要受降雨强度和次降水量影响;主要接收降雨径流,雨量大时有生活污水溢流汇入的B泵站,前池污染物质量浓度在大雨强下先升高后逐渐降低,中雨强下降低,小雨强下变化不大,B泵站前池水质主要受次降水量、前期干旱时间和降雨强度影响;2个泵站前池CODMn质量浓度变化与降雨的响应规律相似,但更多受到与前期干旱时间关联的地表径流冲刷作用影响;连续降雨均导致泵站前池氨氮质量浓度和CODMn质量浓度波动变化较大,而前期干旱时间越长,降雨发生后泵站前池水质越差。
