The high concentration of defects and the continuous interfaces renewal, associated with the milling-induced enhanced atomic mobility, promote different phenomena depending on the materials being milled [5 7].
One cytokine that is known to promote such phenomena is TNF-α [31].
Positive emotions promote many phenomena documented in cognitive psychology, while a negative feeling inhibits them (10).
These results demonstrate that extrinsic factors secreted by senescent MSC are able to promote senescence phenomena in neighboring cells.
A recent paper reported that immunotherapy with activated T cells propagated in this way did not enhance or promote autoimmune phenomena (Yamaguchi et al 2004).
Cell elongation and migration occur in order that networks might form, and the lower gel concentration might well promote these phenomena.
However, chronic treatment with DFMO may promote escape phenomena, including increased uptake of extracellular polyamines, providing necessary amounts of polyamines to the cells.
Repeated episodes of colonisation, and the absence of inbreeding avoidance must contribute to keeping the mutation loads down, and thus promote the phenomenon of speciation in insects.
Curiously, we detected antisense transcripts for soxS, which is a dual transcriptional activator that helps to protect the cell against oxidative stress [ 49], despite the absence of antibiotics or other factors known to promote this phenomenon.
Current contexts for children's development in contemporary industrialised societies have been described by some social commenters as 'toxic' [ 7] promoting the phenomena of 'nature-deficit' [ 8] and 'ecological illiteracy' [ 9] among young children.
