Introduction: Intracerebroventricular (i.c.v.) injection of streptozotocin (STZ) to rodents has been reported as an appropriate model for sporadic dementia of Alzheimer's type (SDAT), characterized by a progressive impairment of memory. However, very little or nothing is known about non-cognitive behavioral effects in the STZ model. This study was carried out in order to show the protective eff...

background: alzheimer’s disease (ad) is characterized by progressive neuronal loss in hippocamp. epidermal neural crest stem cells (epi-ncsc) can differentiate into neurons, astrocytes and oligodendrocytes. the purpose of this study was to evaluate the effects of transplanting epi-ncsc into ad rat model. methods: two weeks after induction of ad by injection of amyloid-β 1-40 into ca1 area of ra...

Introduction: Effects of many flavonoids have been studied on memory, learning and improvement of Alzheimer. Many flavonoids are effective in the improvement of Alzheimer. Since no study has been conducted on the effect of salvigenin on memory and learning, our aim was to examine the effect of this flavonoid. Methods: Intraperitoneal injection of D-galactose at a dose of 120 mg / kg was used f...

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...
