in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
بررسی تآثیر کورکومین بر بیان آکواپورین5 در سلول های سرطانی روده بزرگ انسان(ht-29) سرطان روده بزرگ جزو بیماری های خطرناک بوده و از نظر شیوع سومین سرطان شایع و دومین علت مرگ ومیر ناشی از سرطان در جهان محسوب می شود. خطرابتلا به این سرطان تحت تاثیر دو عامل محیطی وفاکتورهای ژنتیکی می باشد. آکواپورین ها، پروتئین های کانال آبی بوده که نقش مهمی را در انتقال آب در بافتهای اندوتلیالی و اپی تلیالی بر عهد...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...
background : gastric cancer is a common and lethal disease throughout the world. in iran with 7300 new cases annually, it is the first cause of cancer related death in both sexes. regarding the high incidence (10.5/100000 individuals) of gastric cancer and priority of prevalence index in cancer management, in this study we tried to determine 1, 2-3 and 4-5 year point prevalence of the disease...
introduction raman spectroscopy is a vibrational spectroscopic technique, based on inelastic scattering of monochromatic light. this technique can provide valuable information about biomolecular changes, associated with neoplastic transformation. the purpose of this study was to find raman spectral markers for distinguishing normal samples from cancerous ones in different tissues. materials and...
objectives: the iranian cancer network was established in may 2003. our aim was to coordinate re search and treatment programs in all cancer centers in iran in order to save time and money and enable patients, wherever they live, to receive a uniformly high-standard treatment and care. methods: after signing a mutual contract with fellow (collaborator) university and holding some shared session...
background: our knowledge regarding the epidemiology of pancreatobiliary cancers in iran is limited. this study presents the first population-based report on pancreatobiliary cancers performed in five provinces of iran. materials andmethods: data used in this study were retrieved from population-based cancer registries in five provinces of iran (gilan, mazandaran, golestan, ardabil and kerman) ...
female cancer, especially breast and gynecologic cancers are considered multistage disease, highly influenced by risk and protective factors and/or screening preventive modalities. consequences of all these factors result in the trend of change over time.in this comparative study, based on data of national cancer registry of iran 2004 published by iranian ministry of health, age - standard inci...
background: chemokine receptors have been shown to play an important role in the development and metastatic spread of various malignancies. in this study, the gene expression profile of some key chemokine receptors involved in metastasis has been investigated in esophageal and breast cancer cell lines. methods: in a descriptive study, gene expression profile of ccr1, ccr6, ccr7, ccr9, cxcr1, ...
background and aims: among all cancers, colon cancer is common and deadly, yet preventable. the estimated worldwide incidence of colon cancer is more than one million new cases per year. this study was done to identify the epidemiological features and risk factors of colon cancer in different regions of birjand. methods: this retrospective, descriptive analytical study of patients with colon ca...
