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...
alzheimer's disease (ad) is the most prevalent neurodegenerative disorder. it is characterized by formation of amyloid plaques and neurofibrillary tangles in the brain, degeneration of the cholinergic neurons and neural cell death. this study was aimed to investigate the effect of a triazine derivative, c16h12cl2n3s, on learning in an alzheimer's rat model. animals were divided into seven group...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
in the present study, the effect of steroidal anti-inflammatory drug betamethasone (0.12, 0.24 mg/kg, i.p. acutely) on striatal glutamate level in parkinsonian rats was studied using the microdialysis technique. our results showed significant differences (p<0.05) in the level of striatal glutamate between treated and non-treated damaged rats.
some animal models have been used to study alzheimer's disease (ad). ad is an irreversible progressive neurodegenerative disease and the most common cause of dementia. animal studies have shown that there is a relation between decrease in cholinergic functions in the nucleus basalis of meynert (nbm) and loss of learning capability and memory. the aim of this study was to investigate the ef...
abstract the present study was conducted to investigate the effect of using model essays on the development of writing proficiency of iranian pre-intermediate efl learners. to fulfill the purpose of the study, 55 pre- intermediate learners of parsa language institute were chosen by means of administering proficiency test. based on the results of the pretest, two matched groups, one as the expe...
objective(s): intracerebral injection of bone marrow stromal cells (bmscs) is being investigated as a therapeutic tool to prevent alzheimer's disease (ad). our aim was to investigate the effects of bmscs by intrathecal injection in ad rat model. materials and methods: bmscs were obtained from the bone marrow of wistar rat and transplanted into ad rat model via intrathecal injection. the ra...
oxidative stress plays a major role in the pathogenesis of alzheimer's disease (ad) of sporadic origin. the expression of dhcr24 (seladin-1), marker for neuronal oxidative stress and degeneration, has been reported to be altered in the brains of ad patients. in the present study, we investigated the effect of trimetazidine (tmz) on the hippocampal oxidative parameters and the expression of dhcr...
