the cytotoxicity activity of the essential oils from the leaves of achillea wilhelmsii c. koch were studied on six tumor cell lines and a normal cell line w

Background and Objective: Evaluation of tumor proliferative activity may provide a predicting parameter to estimate biologic aggression and a subsequent prognosis that has been evaluated in many malignancies. We have selected renal cell carcinoma (RCC) in this study. To determine tumor proliferative activity, KI67 antibody was applied and results were compared with apoptosis, applying P53 antib...

the macrophages role within the tumor microenvironment has amended by a variety of factors, thus serves a vital role in tissue morphogenesis. the role of macrophages in health and disease differs enormously as the macrophage has shown dual functions. macrophage has a basic role in antigen presentation serving as the first line of defense in diseases. however the presence of cytokines and growth...

we aimed to develop a cost-effective and robust method to predict drug resistance in individualpatients. representative tissue fragments were obtained from tumors removed from femalepatients, aged 24-74 years old. the tumor tissue was taken by a histopathology’s or a surgeonunder sterile conditions. cells obtained by enzymatic dissociation from tumor after surgery, werecultured as a monolayer f...

background: the present study was performed to investigate the effects of trace elements particularity se, zn and cu on tumor genesis in breast cancer. methods: the inhibitory effect of se, zn and cu, on telomerase activity was analyzed in human breast tumor tissues and breast cancer (t47d) cells. tissue specimens from 24 women with benign breast disease and 32 women with breast cancer specimen...
