Goal: The potent anti-cancer activity of Arteether (ARE) has been the focus of many studies. However, the hydrophobic property of this drug limits its application. To increase the bioavailability of ARE, we formulated a nanosystem (NS) of folic acid (FA), chitosan (CS) and Fe3O4 for delivery of ARE against breast cancer. Material and Methods: The CS coated Fe3O4 was synthesized by co-precipitat...

Tumor-related vessel length (TVE) was quantified as the number of pixels skeletonized tumor vessels on ultrafast dynamic contrast-enhanced MRI (UF-DCE MRI). The association between TVE and breast cancer subtypes investigated. Invasive presenting with human epidermal growth factor receptor 2 (HER2) associated increased tumor-related length.

introduction: transient cavitations induced by low frequency irradiation of ultrasound can be used to treat tumors. previous studies in in-vitro experiments have shown that induced cavitation by dual or multiple frequencies of ultrasound is greater than induced cavitation by single frequency irradiation. in this study, we compared and evaluated the treatment effects of dual frequency irradiatio...

conclusions pc-rplnd is one the major operations in the field of urology, which is associated with significant adjunctive surgeries. in appropriate cases, pc-rplnd was associated with good cancer specific survival in tertiary oncology center. results twenty-one patients underwent bilateral pc-rplnd. mean age was 26.3 years (ranged 16 - 47). mean size of retroperitoneal mass after chemotherapy w...

introduction: angiogenesis, the process of new blood vessel formation from pre-existing vessels, has important physiological roles in embryonic development, female reproduction cycle, and wound healing. it is also crucial for pathological processes in several diseases especially tumor growth and metastasis. thereby, inhibition of angiogenesis as an addition to the conventional therapies such as...

Introduction: Epidermal growth factor receptor (EGFR) has been shown to play a critical role in tumor cell growth and its overexpression has been observed in many epithelial tumors. In the field of cancer vaccine research, displaying the peptide mimotope on the surface of phage particles has shown promising results. Methods: In this study using m13-PVIII phage display system, two constructs we...

Objective: Methanol extract of bran and unpolished grain of two traditional aromatic rice genotypes viz. Kalijira and Chinigura were assayed for their activity on the growth and initiation of crown-gall tumors on potato disks. Materials and Methods: Three Agrobacterium tumefaciens (A. tumefaciens) strain AtSl0105, AtTa0112, and AtAc0114 were used as the tumor forming agent. Collected rice was s...

  Background and Objectives: Retinoblastoma is the most common intraocular pediatric malignancy. Angiogenic factor expression such as VEGF (vascular endothelial growth factor) in retinoblastoma can be confirmatory angiogenic potential of this tumor. This study was performed to determine the role of angiogenesis in local invasion of retinoblastoma and its correlation with patients’ sur...
