Developmental stages in experimental liver metastases: Relation to invasiveness
International Journal of Cancer, 1994AbstractWe have previously reported that an invasive morphotype can be evoked in a rat colon carcinoma by transplanting it into pre‐induced subcutaneous granulation tissue. We have now studied the interaction of the same tumor with liver tissue, which is extremely poor in connective tissue in comparison with the subcutaneous site.

An Experimental Study of Plant Community Invasibility
Ecology, 1996A long—term field experiment in limestone grassland near Buxton (North Derbyshire, United Kingdom) was designed to identify plant attributes and vegetation characteristics conducive to successful invasion. Plots containing crossed, continuous gradients of fertilizer addition and disturbance intensity were subjected to a single—seed inoculum comprising ...

Differentiation and neoplasia. Invasion and metastasis; experimental systems
The Journal of Pathology, 1983AbstractIn a series of six transplantable mammary carcinomas and 11 squamous cell carcinomas of mice, evidence of tumour “progression” was obtained in the majority.Progression was evidenced by increased growth rates, transplantability and metastatic capacity, and decreased differentiation and immunogenicity (when present initially).The degree of ...

Experimental island invasion of house mice
Population Ecology, 2015Abstract The ability of invasive species to recurrently establish populations from small numbers of founders, while threatened species struggle at the same low population sizes, is a paradox in conservation biology.

Identifying the biotic factors underlying invasion success into existing communities is critical to understand the dynamics of biological invasions; and while some studies suggest that intraspecific diversity may play an important role, there has not been a systematic evaluation of the evidence.

Non-invasive experimental determination of a CT source model
Physica Medica, 2016Non-invasive methods to determine equivalent X-ray source models of a CT scanner are presented. A high-precision technique called TRIC ("Time Resolved Integrated Charge") was developed and used to characterize the bow tie filters (BT) of the CT scanner installed at Physikalisch-Technische Bundesanstalt (PTB).

Invasive Plant and Experimental Venue Affect Tadpole Performance
Biological Invasions, 2006(Uploaded by Plazi for the IPBES Invasive Alien Species Assessment) Introductions of non-native predators and competitors appear to contribute to worldwide amphibian declines; however, potential negative impacts of invasive plants on habitat quality and amphibian populations have not been examined.

Experimental approaches to problems of invasion and metastasis.
Anticancer research, 1986The highly metastasizing ASML cells and the non-metastasizing AS cells, arisen as spontaneous tumors of the rat, were confronted with rat lung tissue in vitro. Small cubes of the lung were allowed to heal their cut edges, then tumor cells were added. Both tumor cell types adapted their shape to the environment, penetrated the superficial layer of lung ...

[Experimental study on the invasion of glioma in vivo].
Zhonghua yi xue za zhi, 2002To investigate the invasion and metastasis of glioma cell in vivo by implanting C6 glioma cells with the enhanced green fluorescent protein (EGFP) gene into the brain of SD rats.C6 glioma cells were transfected with a plasmid vector (pEGFP-N3) containing the EGFP gene.
