Experimental design is known to be a powerful tool that permits to identify the most active factors in an experiment.
As one of the most active factors, groundwater age is a key to understand the hydrological cycle as well as the associated hydro-ecological processes in a watershed.
An important factor to consider is that the most active agent in NPC, cisplatin, has been omitted from their regimen.
As we compared the relative potencies of various serum growth factors (platelet-derived growth factor, PDGF; lysophosphatidic acid, LPA; basic fibroblast growth factor, bFGF) to desensitize GC-B, we realized that serum acted at dilutions where the above factors could not represent the most active desensitization factor.
PDGF is the best characterized and the most active proliferative factor for OPCs.
Among FGFs, basic FGF (bFGF) which binds to specific RTKs, FGFRs (Mohammadi et al, 1997), is the most active growth factor for endothelium and several studies have demonstrated its expression in breast cancer (Luqmani et al, 1992; Colomer et al, 1997; Smith et al, 1999).
Temperature is one of the most active environmental factors affecting all plant metabolic activities, including amino acid and carbohydrate metabolism [ 55].
Temperature is one of the most active environmental factors that affect all plant metabolic activities, including amino acid and carbohydrate metabolism [ 50].
Vascular endothelial growth factor (VEGF), the most active endogenous proangiogenic factor and an endothelial cell-specific mitogen, is involved in angiogenesis in various types of tumors.
We found that the genes for several transcription factors were upregulated during IgE-sensitization and FcεRI aggregation, including the transcription factors most active during an immune response, such as NFκ B and NFAT (Table. 1f).
