The invasion of Spartina alterniflora significantly affected the local ecosystem of Western Pacific Ocean where Moerella iridescens lives. Five patches with different invasion stages of S. alterniflora were selected and the influence on distribution of M. iridescens was studied on the coast of Wenzhou Bay, China in 2007. The aggregated distribution pattern was proved by using Taylor&#39s power ...

primitive neuroectodermal tumor (pnet) is usually an aggressive, rapidly progressing and metastasizing tumor. occurrence of this type of tumor in the kidney is considered as unusual and few cases have been reported so far. we present a metastatic pnet arising probably from the kidney in a 17-year-old female patient with local invasion and metastasis to the stomach. pnet should be considered as ...

  Background and Objectives: Retinoblastoma is the most common intraocular pediatric malignancy.

This study was performed to determine the role of angiogenesis in local invasion of retinoblastoma and its correlation with patients’ sur...
