The aim of this study was to examine the tissue expression and Iocalisation of the somatostatin receptors （SSTRs） in hormone-refractory （HR） prostate cancer （PCa）. Five SSTRs were evaluated immunohistochemically in 20 radical prostatectomies （RPs） with Gleason score （GS） 3＋3=6 PCa, in 20 RPs with GS 4＋4=8 and 4＋5=9 PCa, and 20 transurethral resection of the prostate specimens with HR PCa. The mean values in the cytoplasm （all five SSTRs were expressed）, membrane （only SSTR3 and SSTR4 were expressed） and nuclei （only SSTR4 and SSTR5 were expressed） of the glands in HR PCa were 20-70% lower than in the other two groups, the differences being statistically significant. All five SSTRs were expressed in the smooth muscle and endothelial cells of HR PCa, the mean values being lower than in the other two groups. In conclusion, this study expands our knowledge on the expression and Iocalisation of five SSTRs in the various tissue components in the HR PCa compared with hormone-sensitive PCa.

International Journal of Geosciences 2014年第3期5卷 239-246页

作者： Nivaor rodolfo Rigozo Instituto Nacional de Pesquisas Espaciais(INPE) Sao Jose dos CamposBrazil

This paper presented a study of the effects of atmospheric pressure in the time series of muon detector using the method of spectral analysis of iterative regression. In which it observed that the periods of 4.8, 5.7, 7.0, 8.7, 10.7, 14.1, 16.2, 21.0, 31.2 and 356.7 days present in the amplitude spectrum of atmospheric pressure are also present in the amplitude spectra of muons data. Also it observed that the standardization of muons data to eliminate the effects of atmospheric pressure is efficient for periods under 7 days.

The Response of Benthic Foraminiferal Assemblages to Copper Exposure: A Pilot Mesocosm Investigation

引用

Journal of Environmental Protection 2012年第4期3卷 342-352页

作者： Frontalini Fabrizio Coccioni rodolfo Dipartimento di Scienze della Terra della Vita e dell’Ambiente (DiSTeVA) Università degli Studi di Urbino “Carlo Bo” Urbino Italy.

Controlled experiments, including mesocosms and laboratory cultures, are used to identify a potential speci?c cause- effect relationship that has been previously inferred in field studies. In this study, a series of mesocosm experiments are carried out to assess the impact of different concentrations of copper on benthic foraminiferal assemblages over time. This pilot investigation documents that Cu contamination has a detrimental effect on foraminifera when compared to original and control samples. In particular, increased concentrations of Cu (normally higher than 120 μg/l) lead to a lowering of foraminiferal density and diversity and an increased occurrence of abnormalities. This study thus supports that the use of an experimental approach is suitable for investigating the response of benthic foraminifera to stress including pollution. Moreover, the application of mesocosms represents an innovative tool to be placed alongside field studies and culture experiments.
