Background and purpose: The 4T1 cell line is a laboratory model used in the study of tumors biology. This cell line is very tumorigenic with high metastatic capacity in different organs. In this study, histology and immunohistochemistry methods were used to investigate the structure and localization of Na+/K+- ATPase enzyme in 4T1 cells induced breast cancer tumor in Balb/c nu mice. Material...
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...
We study the phase diagram of the four dimensional O(4) model with first (β1) and second (β2) neighbor couplings, specially in the β2 < 0 region, where we find a line of transitions which seems to be second order. We also compute the critical exponents on this line at the point β1 = 0 (F4 lattice) by Finite Size Scaling techniques up to a lattice size of 24, being these exponents different from...
To investigate the effects of the two-pore-domain potassium (K2P) channel TASK-3 in a syngeneic murine model for malignant glioma. Malignant or high-grade glioma (WHO grade III and IV) are the most common and most aggressive primary brain tumors in adults. Despite aggressive multimodal therapy, the outcome of patients with malignant glioma remains poor. However, recent phase I and II trials hav...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
Dynamic cellular manufacturing systems, Mixed-integer non-linear programming, Production planning, Manufacturing attributes This paper presents a novel mixed-integer non-linear programming model for the design of a dynamic cellular manufacturing system (DCMS) based on production planning (PP) decisions and several manufacturing attributes. Such an integrated DCMS model with an extensi...
Cell formation (CF) problem is one of the most important decision problems in designing a cellular manufacturing system includes grouping machines into machine cells and parts into part families. Several factors should be considered in a cell formation problem. In this work, robust optimization of a mathematical model of a dynamic cell formation problem integrating CF, production planning and w...
the aim of this study was to assess the predictive effect of the ebmt risk score on the outcomes of allogeneic stem cell transplantation in a relatively homogenous group of acute myelogenous leukemia (aml) patients regarding the occurrence of acute and chronic graft versus host disease (gvhd). this historical cohort study included adult patients (≥ 15 years old) with aml (n=363) who received al...
مقدمه: لنفوم سینوس ماگزیلاری، صرف نظر از اولیه یا ثانویه، تقریباً در تمامی موارد به فرم nonhodgkin's تیپ سلول b گزارش شده است و اغلب با تظاهراتی چون علایم درگیری سینوس ها، حفره بینی، دهان و اربیت بروز می کند. معرفی بیمار: بیمـار، مرد 20 سـاله ای است که بدون هیچ گونه علایـمی دال بر درگیری سیستم سینونازال و اربیتال مراجعه کرد. تنها علامت و شکایت بیمار احساس توده در سقف دهان و لق شدگی دو دندان...
