Background: Artemisia diffusa contains a new type of sesquiterpene lactone with an endoperoxide group (Tehranolide). Objective: Due to the existing similarity between the structures of Tehranolide and Artemisinin, it was hypothesized that Tehranolide would have similar effects as Artemisinin. In this study, the immunotherapeutic effec-tiveness of Tehranolide was investigated by direct intra-tum...

PURPOSE Evaluation of vascular disruptive activity in orthotopic models as potential surrogate biomarkers of tumor response to the microtubule-stabilizing agent patupilone. EXPERIMENTAL DESIGN Mice bearing metastatic B16/BL6 melanoma and rats bearing mammary BN472 tumors received vehicle or efficacious patupilone doses (4 and 0.8-1.5 mg/kg i.v., respectively). Tumor vascularity assessment by ...

tumor cells are dependent on angiogenesis to obtain oxygen and nutrients and also development of their new vascular network. vegf as an important stimulator of angiogenesis and endostatin as an inhibitor play a fundamental role in this process. this study was designed to investigate the effect of six weeks of resistance training on tumor tissue vegf andendostatin in mice with breast cancer. for...

objective(s): interleukin-12 (il-12) as a cytokine has been proved to have a critical role in stimulating the immune system and has been used as immunotherapeutic agents in cancer gene therapy. chitosan as a polymer, with high ability of binding to nucleic acids is a good candidate for gene delivery since it is biodegradable, biocompatible and non-allergenic polysaccharide. the objective of the...

BACKGROUND In this study, we aimed to establish the rabbit VX2 limb tumor model, and then prepare a "necrotic zone" as a safe margin by volumetric modulated arc therapy and simultaneous integrated boost (VMAT-SIB) technique applied in the areas where the tumor is located adjacent to the bone (GTVboost area). MATERIAL AND METHODS Rabbits in the control group (n=10) were not treated, while thos...

BACKGROUND The aim of this paper was to evaluate the validity of tumor volume measurement using diffusion-weighted (DW) imaging in cervical cancer. METHODS In this retrospective study, 22 patients, who underwent preoperative 3.0 T MR examinations with DW imaging were evaluated. Tumor volume measurement by oblique axial (short axis to the uterine cervix) T2-weighted imaging was performed by ma...

BACKGROUND O-(2-18 F-fluoroethyl)-L-tyrosine-(FET)-PET may be helpful to improve the definition of radiation target volumes in glioblastomas compared with MRI. We analyzed the relapse patterns in FET-PET after a FET- and MRI-based integrated-boost intensity-modulated radiotherapy (IMRT) of glioblastomas to perform an optimized target volume definition. METHODS A relapse pattern analysis was p...
