Tumoral Growth
In addition to its well-known homoeostatic actions in the cardiovascular system, ET-1 has been shown to constitute a potent growth regulatory peptide in various tissues. We have studied the expression of ET-1 and its receptors (ETAr and ET-Br) in human meningiomas (n = 35) as well as their involvement in cellular growth. By PCR of reversetranscribed RNA we detected ET-1 mRNA in 91% (32 of 35), ...
متن کاملTumoral cystitis in children.
Three children aged 3-11 years had ultrasonography of the urinary tract for the investigation of dysuria and haematuria. A bladder mass was seen in these 3 children. One child had computed tomography scan, cystoscopy and bladder biopsy because rhabdomyosarcoma was considered. The biopsy revealed an inflammatory process.

In this retrospective study,clinical data and radiological features of nine cases of idiopathic tumoral calcinosis are reviewed. Imaging features, particularly magnetic resonance imaging findings are detailed.
متن کاملStochastic models for tumoral growth.
Strong experimental evidence has indicated that tumor growth belongs to the molecular beam epitaxy universality class. This type of growth is characterized by the constraint of cell proliferation to the tumor border and the surface diffusion of cells at the growing edge. Tumor growth is thus conceived as a competition for space between the tumor and the host, and cell diffusion at the tumor bor...
