Ewing sarcoma is a malignant pediatric bone and soft tissue tumor. Although the 5-year survival rate of localized disease approaches 75%, the prognosis of metastatic and/or therapy-resistant disease remains dismal despite the wide use of aggressive therapeutic strategies. We previously reported that high expression of glutathione S-transferase M4 (GSTM4) in primary tumors correlates with poor p...

Radiation induced sarcoma is a rare but recognized complication of radiotherapy and is associated with poor prognosis, frequently occurs 5 years after completion of treatment. We report radiation-induced sarcoma in a 42 years old male, involving the left parietooccipital scalp region following treatment of brain tumor with craniotomy and post-operative radiation with 60Co machine. Diagnosis of ...

against itself but not against others. Each new tumor induced is therefore expected to have a new antigemc individuality. However, cross-reactivity between independently induced tumors has occasionally been reported (2, 5 , 6, 8—10,12, 13). The notion that antigenic determinants may be repeated in different tumors opens the possibility of antigenic typing. The observations of cross-reactivity...

sativum L.) is now believed due to the properties of its active principle, allyithiosuffinicallyl ester, allicin (6). Allicin is produced by enzymatic degra dation of alum, S-allyl-frcysteine-S-oxide. Inhibi tion of sulfhydryl enzymes is associated with the presence of the —SO—S—grouping(11). The role of suffhydryl groups in cell division and mitoses has been reviewed by Barron (1) : an i...

be achieved by either homologous mouse type C replicating viruses or heterologous viruses capable of replicating in such cells (8). The increased levels of Moloney sarcoma specific RNA might be achieved by increased rates of transcription of the MSV genome or decreased rates of degradation of the sarcoma specific RNA. In addition, as a secondary effect, increases of sarcoma RNA may occur by gen...

Introduction: There is many ways to assessing the electrical conductivity anisotropyof a tumor. Applying the values of tissue electrical conductivity anisotropyis crucial in numerical modeling of the electric and thermal field distribution in electroporationtreatments. This study aims to calculate the tissues electrical conductivityanisotropy in patients with sarcoma tumors using diffusion tens...

Kaposi ' s sarcoma (KS) i s a mul t i focal angioproliferative disease characterised by transdifferentiation of human herpes virus type 8 (HHV-8) infected endothelial cells into spindle-shaped cells, followed by cytokine-dependent transformation, proliferation, neovascularisation and inflammatory cell infiltration. Trans-differentiation is the conversion of differentiated cells either morpholog...

for centuries, aloe vera has been used by many different cultures. the ancient greeks, the romans, the babylonians, indians and the chinese have all used aloe vera as a medicinal plant. one of the common experimental cancer models is sarcoma-180. when aloe was administered to mice bearing s-180 tumors, the tumor growth was inhibited. aloe vera is a dietary supplement and not a regulated drug. t...
