Introduction: Donepezil (DON), an Acetylcholinesterase Inhibitor (AChEI), is widely used in the treatment of Alzheimer’s Disease (AD). The current study aimed at evaluating the effect of donepezil hydrochloride on pyramidal neuron response in CA1 region of a rat model of AD. Methods: In the current experimental study, adult male Wistar rats were randomly divided into four groups: Nucleus Basal...

Asthma is an inflammatory and chronic disease that affects about 300 million people globally. The disease is more common in developed countries. The increase in the prevalence of asthma is not only due to genetic factors, but also to many environmental factors related to urbanization and type of nutrition. It has been reported that obesity is an independent risk factor for asthma and obese chil...

in traditional chinese medicine, arsenous compounds, including arsenic trioxide (ato), are often used to treat many diseases, which are safe and effective. recently, studies have indicated that th17– il-17 involved in the pathogenesis and development of asthma. the goal of this study was to investigate the effect and mechanism of ato on asthma, especially the th17– il-17 axis. we used oval bumi...

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...

Objective: This study aimed to investigate the prediction of asthma control on the basis of perceived stress, locus of control, and self-efficacy in adult patients with asthma.  Methods: This was a descriptive-correlative and cross-sectional study.The solecty of this study is all asthmatic patients in Tehran. our sample consisted of 100 participants who were selected by purposeful sampl...

Asthma is the most common cause of recurrent wheezing, cough and dyspnea in childhood. Delay in diagnosis and lack of appropriate treatment can cause sustained changes which decrease respiratory capacity of children in future. Therefore, identifying the symptoms relating to asthma is the key for timely diagnosis and treatment of this disease. This study was done to investigate asthma incidence ...

objectives: crocin, a constituent of saffron and yellow gardenia, possesses anti-nociceptive effects. in the present study, we investigated the effects of intra-fourth ventricle injection of crocin in a rat model of orofacial pain. the contribution of opioid system was assessed using intra-fourth ventricle injection of naloxone, an opioid receptor antagonist. materials and methods: a guide cann...

BACKGROUND Epidemiological studies have revealed that intrauterine growth retardation (IUGR) or low birth weight is linked to the later development of asthma. Epigenetic regulatory mechanisms play an important role in the fetal origins of adult disease. However, little is known regarding the correlation between epigenetic regulation and the development of asthma following IUGR. METHODS An IUG...
