گیاه اگروستما گیتاگو علف هرز مزارع گندم استان اردبیل می باشد. نانولیپوزوم ها حامل دارو وعوامل فعال هستند واثر بخشی داروها را بر روی سلول های سرطانی افزایش می دهند. هدف: هدف از این مطالعه بررسی اثر سیتوتوکسیک عصاره لیوفیلیزه گیاه اگروستما گیتاگو و مقایسه آن با فرم نانو لیپوزومی این عصاره بر روی رده سلولی آدنوکارسینومای معده انسان (ags) می باشد. روش: پس از جمع آوری دانه ها، عصاره لیوفیلیزه آنها...
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...
Background & Aims: Gastric cancer is the second common cancer in Iran and it has unfortunately no diagnostic signs in early stages. Considering the role of genetic and environmental factors in the development of gastric cancer, this study aimed at evaluating DNA-content of stomach cells in patients with gastric cancer in order to find a reliable index for prediction of disease prognosis and pro...
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...
Background and Objective: Nowadays, it has been proven that the immune system plays a major role in the occurrence or treatment of some cancers. The PDL-1 proteins are among the components of the immune system, which are expressed in different body cells, including B cells and T cells. In this regard, the present study was conducted to determine the frequency of PDL-1 protein expression and its...
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...
