Hepatocyte growth factor/Scatter factor in the eye
Progress in Retinal and Eye Research, 2000Hepatocyte growth factor, also known as scatter factor (HGF/SF) is a multipotential cytokine which can produce a range of responses in target cells and its influence in the eye in health and disease is just beginning to be appreciated. Usually HGF/SF is synthesised by mesenchymally derived cells and targets and signals epithelial cells in a paracrine ...

A word u appears as a factor of another word v as it is: in one piece. When u is a subword of v, u may be scattered as several factors. We consider the case in between and put some restrictions on the number of factors as to which u is allowed to be scattered. A large class of partial orders which are generalizations of factors and subwords is obtained.

The Journal of Chemical Physics, 1984
Waller–Hartree calculations of molecular incoherent scattering factors S( μ) for CH4, NH3, and H2O are reported to provide an unambiguous comparison with recent calculations of S( μ) for these molecules made by integration of impulse approximation Compton profiles.

Scatter Factors in Tumor Progression
2006Scatter factors are soluble proteins that activate tyrosine kinase receptors belonging to the MET oncogene family. These receptors drive a physiological genetic program known as “invasive growth” which underlies tissue morphogenesis and repair. Aberrant execution of this program in time and localization has been associated to neoplastic transformation,

Scatter factor corrections for elongated fields
Medical Physics, 1989Measurements have been made to determine scatter factor corrections for elongated fields of Cobalt‐60 and for nominal linear accelerator energies of 6 MV (Siemens Mevatron 67) and 18 MV (AECL Therac 20). It was found that for every energy the collimator scatter factor varies by 2% or more as the field length‐to‐width ratio increases beyond 3:1.

Activated human neutrophils release hepatocyte growth factor/scatter factor
European Journal of Surgical Oncology (EJSO), 2001Hepatocyte growth factor or scatter factor (HGF/SF) is a pleiotropic cytokine that has potent angiogenic properties. We have previously demonstrated that neutrophils (PMN) are directly angiogenic by releasing vascular endothelial growth factor (VEGF). We hypothesized that the acute inflammatory response can stimulate PMN to release HGF.To examine the ...

The biology of hepatocyte growth factor/scatter factor
BioEssays, 1992AbstractHepatocyte growth factor, a potent mitogen for epithelial and other cell types, and scatter factor, a stimulant of epithelial cell motility are identical. In addition to these mitogenic and motogenic functions, the factor has been shown to be an epithelial morphogen and also has antiproliferative effects in some cancer cell lines.

Photon Scattering – Form Factors
2017Scattering experiments are the paradigm of quantum mechanical measurements. A beam of atoms, ions, electrons or photons – to mention but a few possibilities – is generally created in an accelerator. A detector is used to find the energy of the scattered particle (or the absolute value of the momentum) and the scattering angle. From this, one calculates

Purification and characterization of scatter factor
1991Scatter factor is a fibroblast-derived protein which disrupts and scatters epithelial colonies and enhances the local movement of individual epithelial and endothelial cells. The factor purified from mouse fibroblasts by cation-exchange and reverse phase chromatography is a dimer of 57 kD and 30 kD protein subunits (A and B subunits), is active at ...

Regulation of angiogenesis by scatter factor
1997Scatter factor (SF, hepatocyte growth factor) is a cytokine that stimulates motility, proliferation, and morphogenesis of epithelia. These responses are transduced through a tyrosine kinase receptor that is encoded by a proto-oncogene (c-met). SF is a potent angiogenic molecule, and its angiogenic activity is mediated, in part, through direct actions ...
