Five permanently established xenograft lines of human soft tissue sarcomas were irradiated with single doses of 5.8 MeV d(14)+Be neutrons and of 60Co rays, respectively, at several dose levels to generate dose response relationships. The tumors were clamped ten minutes prior to and during
Mechanisms of hypoxia-related angiogenesis are important for uterine smooth muscle tumors. Factors that are related to angiogenesis during hypoxia include vascular endothelial growth factor (VEGF), hypoxia inducible factor 1α (HIF1α), T-cell intracellular antigen1 (TIA1), eukaryotic translation
Hypoxia is now established as a key factor influencing the pathophysiology of malignant growth. Among other effects, hypoxia modulates the expression of a multitude of genes through the induction of hypoxia-inducible transcription factors. This differential gene expression favors angiogenesis, cell

Lung metastasis of leiomyosarcoma that protrudes into the left atrium is an extremely rare condition. Severe complications may occur that prominently increase the mortality during the perioperative period. Currently, the anesthetic management reports are limited and there is no generally
OBJECTIVE
Doxorubicin-based treatment is standard therapy for metastatic uterine leiomyosarcoma. There is no standard second-line therapy. We determined activity of fixed-dose rate gemcitabine plus docetaxel as second-line treatment for metastatic uterine leiomyosarcoma.
METHODS
Eligible women with
As part of a broader effort to identify postreceptor signal regulators involved in specific diseases or organ adaptation, we used an expression cloning system in Saccharomyces cerevisiae to screen cDNA libraries from rat ischemic myocardium, human heart, and a prostate leiomyosarcoma for entities
Endosialin (CD248, TEM-1) is expressed in pericytes, tumor vasculature, tumor fibroblasts, and some tumor cells, including sarcomas, with limited normal tissue expression, and appears to play a key role in tumor-stromal interactions, including angiogenesis. Monoclonal antibodies targeting endosialin
The majority of hematopoietic malignancies have aberrancies in the retinoblastoma (Rb) pathway. Loss in Rb function is, in most cases, a result of the phosphorylation and inactivation of Rb by the cyclin-dependent kinases (cdks), main regulators of cell cycle progression. Flavopiridol, the first cdk
Secreted frizzled related protein 1 (sFRP1) is a modulator of Wnt signaling. Recently, aberrations of Wnt signaling were reported to be involved in the pathology of various human neoplasms. We investigated the expression and function of sFRP1 in uterine leiomyomas. Secreted FRP1 expression was
BACKGROUND
Adult respiratory distress syndrome (ARDS) is characterized by progressive hypoxemia, diffuse bilateral pulmonary infiltrates and normal left ventricular function.
METHODS
A 58-year-old woman developed ARDS following extensive cytoreductive surgery for a widely disseminated
Uterine fibroid or leiomyoma is the commonest benign uterine tumour. Its occurrence in the postmenopausal age group is rare and if enlargement of the fibroid noted during this time, the diagnosis of leiomyosarcoma is provisional until proven otherwise. A case of a postmenopausal woman with a huge
Results from our laboratory have put a question mark on the existence of a direct quantitative relationship between tumor hypoxia and HIF-mediated protein expression in cancers of the uterine cervix. In the present study, this subject has been further explored by the analysis of HIF-related marker
Paragangliomas (PGLs) belong to the most hereditary endocrine tumours. The existence of mutated HIF2A in these tumours, the role of oncometabolites on HIFs stabilisation and a recent concept proposing how hereditary PGLs converge on the hypoxia-signalling pathway, brought solid evidence of the
Hereditary leiomyomatosis and renal cell cancer (HLRCC, also known as multiple cutaneous and uterine leiomyomatosis, MCUL) is a highly penetrant autosomal dominant tumor predisposition syndrome characterized by benign leiomyomas of the skin and the uterus. Renal cell carcinomas, occurring in a
