Electromagnetic field (EMF) radiations emitted from mobile phones may cause structural damage to neurons. With the increased usage of mobile phones worldwide, concerns about their possible effects on the nervous system are rising. In the present study, we aimed to elucidate the possible effects of prenatal EMF exposure on the cerebellum of offspring Wistar rats. Rats in the EMF group were exposed to 900-MHz pulse-EMF irradiation for 6. h per day during all gestation period. Ten offspring per each group were evaluated for behavioral and electrophysiological evaluations. Cerebellum-related behavioral dysfunctions were analyzed using motor learning and cerebellum-dependent functional tasks (Accelerated Rotarod, Hanging and Open field tests). Whole-cell patch clamp recordings were used for electrophysiological evaluations. The results of the present study failed to show any behavioral abnormalities in rats exposed to chronic EMF radiation. However, whole-cell patch clamp recordings revealed decreased neuronal excitability of Purkinje cells in rats exposed to EMF. The most prominent changes included afterhyperpolarization amplitude, spike frequency, half width and first spike latency. In conclusion, the results of the present study show that prenatal EMF exposure results in altered electrophysiological properties of Purkinje neurons. However, these changes may not be severe enough to alter the cerebellum-dependent functional tasks. © 2013 IBRO.

It was demonstrated that treatment with beta amyloid (Aβ) led to extreme alterations in the intrinsic electrophysiological properties of CA1 pyramidal neurons. Also, malfunction of the cholinergic system is correlated to the memory and cognitive impairments. Several new studies have suggested that Berberis vulgaris can act as a cholinesterase inhibitor. The present study aimed to investigate the effects of berberine (BER) on the Aβ-induced impairments in learning and memory. The male Wistar rats were divided into 4 groups of Sham, BER, Aβ and Aβ+BER. The administration of BER or its vehicle started immediately after the injection of Aβ and followed by 13 days. Then, the animals were tested for learning and memory performance using the Morris water maze (MWM) and passive avoidance tests. Then, they were sacrificed for the whole cell patch clamp recording. The results of the MWM and passive avoidance tasks indicated that administration of the BER in the Aβ+BER group prevented the memory impairment induced by Aβ. The results of the whole cell patch clamp also showed that administration of the BER restored the Aβ-induced impairments in the firing frequency, half-width and rebound action potential. These results suggested that administration of the BER could ameliorate neurotoxicity induced by Aβ. However, this neuroprotection impact could be resulted from the balance effect of the Ca2+ entry. The optimal level of Ca2+ entry by BER could be a major factor that modified the function of the Ca2+-activated K+ channels and decreased the half-width in the Aβ treated rats. © 2015 Elsevier B.V.

Organophosphorous (OPs) pesticides are the most widely used pesticides in the agriculture and home. However, many acute or chronic poisoning reports about OPs have been published in the recent years. Mitochondria as a site of cellular oxygen consumption and energy production can be a target for OPs poisoning as a non-cholinergic mechanism of toxicity of OPs. In the present review, we have reviewed and criticized all the evidences about the mitochondrial dysfunctions as a mechanism of toxicity of OPs. For this purpose, all biochemical, molecular, and morphological data were retrieved from various studies.Some toxicities of OPs are arisen from dysfunction of mitochondrial oxidative phosphorylation through alteration of complexes I, II, III, IV and V activities and disruption of mitochondrial membrane. Reductions of adenosine triphosphate (ATP) synthesis or induction of its hydrolysis can impair the cellular energy. The OPs disrupt cellular and mitochondrial antioxidant defense, reactive oxygen species generation, and calcium uptake and promote oxidative and genotoxic damage triggering cell death via cytochrome C released from mitochondria and consequent activation of caspases. The mitochondrial dysfunction induced by OPs can be restored by use of antioxidants such as vitamin E and C, alpha-tocopherol, electron donors, and through increasing the cytosolic ATP level. However, to elucidate many aspect of mitochondrial toxicity of Ops, further studies should be performed. © 2013 Elsevier Inc.


This hypothesis would help to elevate safety in nanogold-therapy of some cancers. It has no previous record in published media and there is no existing protocol for what is expressed in this paper. The hypothesis makes some experimental recommendations for future research at the interface of nanotechnology and biological systems. It is about reducing toxicity and side effects of nanogold particles (NGPs) in cancer patients treated with antibody-nanogold therapeutics. The hypothesis expresses that how to eliminate idle NGPs from blood stream of treated cancer patients in order to reduce undesirable deposition and accumulation of NGPs in non-target tissues and organs in post therapy. In this regard, at the end of therapy period, blood of treated cancer patient which contains idle nanogold-antibodies is passed through a machine named " Nanogold detoxifying machine" (NDM). This machine behaves like " hemodialysis machine" used for patients with lost kidney function but, instead of dialysis membrane, NDM is equipped with impermeable membrane containing nanotubes to which cancer specific-antigens (CSAs) are attached. While blood circulates in NDM, CSAs attract and immobilize the idle nanogold-antibodies. Implementation of NDM clears patient's blood from idle nanogold-antibodies which were not attached to their targets, the cancer cells. Elimination of idle NGPs from blood would minimize side effects resulting from their deposition or accumulation on non-target cells or tissues. Since NDM reduces anxieties about side effects, it would provide patients with better feelings too. NDM would enhance efficacy of NGPs targeted toward specific cancers. Before using it for clinical trials in human cases, NDM should pass animal evaluations; however, research works should optimize its implementation. I think NDM method holds great promise to reduce the time, effort, and expense in cancer research, screening, detection, and therapy. © 2013 Elsevier Ltd.

An examination of top-cited articles is a tool that can be used to identify and monitor outstanding scientific research. The goal of this study was to identify and analyze the characteristics of the 100 top-cited articles published in international journals dedicated to psychiatry. The Science Citation Index Expanded provided by the Thomson Reuters Institute for Scientific Information Web of Knowledge was searched in December, 2011, and 128 journals were identified in the subject category "Psychiatry." Each journal was searched on the Web of Science under "Publication Name" and the results were sorted by category "Times Cited." The 100 top-cited articles were recorded, and the list was analyzed with regard to journals, number of citations, authors, year, institution, and country of origin. The original research articles of the 100 top-cited articles were classified into one of five categories: scale/measurement, descriptive/epidemiology, mechanism, management, and imaging. The 100 top-cited articles were cited between 26,578 and 781 times; they were published between 1957 and 2005, with the largest number (35) published in the 1990s. The articles appeared in 24 journals, with more than half published in the Archives of General Psychiatry (56), followed by the American Journal of Psychiatry (6), and Psychological Medicine (6). Articles that dealt with the development, application, or validity of measurements led the list of top-cited psychiatric publications (43) and had a significantly higher number of citations compared with the rest of the articles. The time and language of publication, field of study, country of origin, and journal in which the paper appeared are possible determinants of the likelihood of citation and impact.

A carbon nanotube (CNT) paste electrode was constructed for the determination of carbidopa (CD). Owing to the unique structure and extraordinary properties of CNTs, the modified electrode has shown an obvious electrocatalytic activity towards oxidation of CD, which leads to lowering its overpotential by more than 400 mV. Also, the values of electron transfer (α=0.34). and diffusion coefficient (D 0=5.9×10 -6 cm 2/s) for CD were calculated. Under the optimum conditions, the oxidation peak currents were linearly proportional to the concentration of CD in the range from 0.07-600.0 μM. The detection limit was 29.0 nM. Then the modified electrode was used to determine CD in an excess of acetaminophen (AC). Finally, the proposed sensitive and simple electrochemical method was successfully applied to CD and AC determination in urine samples. © 2011 by ESG.

Background: Cigarette Smoking is a recognized cause of systemic disorders such as bronchogenic, carcinoma, and cardiovascular diseases and hence prompt and effective interventions are required for its elimination. Thus, This Meta-analysis was carried out for an adult population of west of Iran in order to estimate of prevalence smoking in this area. Methods: We examined related to documentation by searching in published and non-electronic databases. Data were extracted based on variables such as the year of the study, sex, age group, and the prevalence of smoking. Based on the results of heterogeneity, we used fixed or random effects model to assessment the overall prevalence of cigarette smoking. All analyses were accomplished via STATA 11 software. Results: Totally, 25, 990 subjects (13005 males) were investigated. Meta-analysis in men and women indicated prevalence of 22.9 (20.6-25.2) and 0.6 (0.3-0.9) respectively. Conclusions: It was found that more than one-fifth of men from 15 year to 64-year-old of west of Iran smoked cigarette. Providing an education on harmful effects of smoking to the adult population would be a valuable means for reducing destructive consequences of smoking.


The Brief Assessment of Cognition in Schizophrenia (BACS) is designed for assessment of cognitive function in patients with schizophrenia. Versions of the BACS in English and other languages have been shown to be as sensitive to cognitive dysfunction as a standard test battery, with the advantage of brief administration and scoring time. The present study aimed to test the concurrent validity of the Persian version of the BACS (Persian-BACS). A group of 50 patients with schizophrenia-spectrum disorders and a group of 50 healthy controls received the Persian-BACS in a first session, and in a second session a standard neurocognitive battery. Cronbach's alpha for the Persian-BACS was 0.74. All the Persian-BACS subscales were significantly correlated with the corresponding standard neurocognitive subscales and the Pearson correlation of the composite scores from the two instruments was 0.71. Moreover, a one-factor solution was found that accounted for 67.9% of the variance. Finally, the Persian-BACS demonstrated high ability to discriminate patients with schizophrenia from healthy controls. Good psychometric properties of the Persian-BACS suggest that it is a useful tool for assessing cognition in schizophrenic patients with Persian as their primary language. © 2013 The Authors.

Previous studies have examined the relationship between problematic Internet use (PIU) with pathological gambling and impulsivity. However, few studies have investigated the association between PIU and other impulse control disorders. This study aimed to assess whether PIU is related to compulsive buying, kleptomania, trichotillomania, intermittent explosive disorder, and pyromania, among a sample of Iranian university students. A cross-sectional study design was used among a random sample of (n=950) university students. Self-reported questionnaires, including demographic, Problematic Internet Use Questionnaire (PIUQ) and Minnesota Impulse Disorders Interview were utilized. The prevalence of PIU was 21.2 percent. Students with diagnosis of either compulsive buying, or intermittent explosive disorder, or pyromania had significantly higher scores on PIUQ compared to the students without the diagnosis. Multivariate regression analyses indicated that in the male gender, the diagnosis of either compulsive buying or intermittent explosive disorder were significant predictors of the risk of the PIU. The results support the proposal that PIU should be considered as a spectrum of impulse control disorder. © 2012, Mary Ann Liebert, Inc.

Many socio cultural variables could be affect eating disorders in Asian countries. In Iran, there are few researches regarding eating disorders and their contributing factors. The aim of this study is to explore frequency of eating disorders and their risk factors in an Iranian population. About 1204 participants were selected aged between fourteen to 55 years. Frequency of eating disorders and effects of variables such as demographic characteristics, Body Mass Index (BMI), use of media, body dissatisfaction, self-esteem, social comparison and social pressure for thinness in individuals with and without eating disorders, were assessed. The prevalence of eating disorders was 11.5% that included 0.8% anorexia nervosa, 6.2% full threshold bulimia nervosa, 1.4% sub threshold anorexia nervosa and 30% sub threshold binge eating disorder. Symptoms of bulimic syndrome were greater in males. In Iran, eating disorders and related problems are new issue that could be mentioned seriously The identification of these disorders and their related contributing factors are necessity of management and preventive programs planning.
