Ochratoxin A in dried figs, raisings, apricots, dates on Iranian retail market  [PDF]
Ebrahim Rahimi, Amir Shakerian
Health (Health) , 2013, DOI: 10.4236/health.2013.512282
Abstract:

Ochratoxin A (OTA) is among the most important mycotoxins, and the International Agency for Research on Cancer (IARC) classifies it as possibly carcinogenic to humans (group 2B). A total of 121 samples of dried fruits from the central zone of Iran were analyzed for OTA by enzyme linked immunosorbent assay (ELISA) technique. The recovery percentages of OTA in spiked dried fruit samples at concentrations of 5, 10 and 20 ng/g were found to be 84.9%, 89.3% and 90.4% as mean, respectively. OTA was found in 20.7% of the analyzed samples by average concentration of 6.7 ± 3.9 ng/g. The incidence rates of OTA contamination in dried fig, raising, apricots, and date samples were 10.4%, 44.7%, 6.7% and 10.0%, respectively. The concentrations of OTA in 7.9% of contaminated dried raising samples and 2.1% of dried fig samples were higher than maximum tolerance limit accepted by European Union (10 ng/g). This value reflects that the analyzed samples have a minimal contribution to toxicological risk. To our best knowledge, the present study is the first report of the presence of OTA by ELISA in dried fruit samples in Iran.

 

Incarnation or Divine Transmigration in Rumi’s Masnavi Ma’navi
Ebrahim Rahimi Zangene
Studies in Literature and Language , 2012, DOI: 10.3968/j.sll.1923156320120402.1055
Abstract: The Resurrection of man according to actual form of his deed is one of the most significant issues among the Islamic Mystics and scholars that is people with their deeds and actions shape the form for their soul expression, which is the real substance of their soul. Their Purgatorial face will be embodied on the basis of their inward soul expression. This concept has wildly been expressed by Rumi in Masnavi Ma’navi, in which he has given a vivid definition. In the present study, the researcher has surveyed the concept of incarnation and the way human behavior changes his nature, soul and spirit in line with explaining its difference with transmigration from Rumi’s viewpoint, which is evaluated with respect to Quranic verses of Household. Key words: Incarnation; Divine Transmigration; Soul; Soul expression
State Anxiety Affects on Balance Scores in Young Female University Students
A. Rahimi,Z. Ebrahim Abadi
Journal of Medical Sciences , 2012,
Abstract: The current study focused on the effects of anxiety on balance index in young female university students. A group of 15 female students with a high anxiety score (higher than 42 in Spielberger’s score) and a group of 15 female students with a low anxiety score (lower than 42 in Spielberger’s score) were recruited in this study. The Anteroposterior (AP), Mediolateral (ML) and the overall dynamic Stability Index (SI) of the subjects were recorded by use of a Biodex stabilometer (Biodex Stabilometer System, USA) and were compared with each other. The results revealed a significant difference between the two groups. The subjects with a high anxiety score showed a stability index higher than those in low anxiety group (p<0.005) which simply means significantly less stability in this group. In conclusion, this study showed a less stability index existed in subjects with higher anxiety scores. It could be inferred from the results that carrying out a state anxiety assessment concurrently with a clinical balance test certainly help clinicians to predict the hidden associated instability disorders of the patients.
Escherichia coli O157:H7/NM prevalence in raw beef, camel, sheep, goat, and water buffalo meat in Fars and Khuzestan provinces, Iran
Ebrahim Rahimi,Hamid Reza Kazemeini,Mohammad Salajegheh
Veterinary Research Forum , 2012,
Abstract: Enterohemorrhagic Escherichia coli (EHEC) of the O157:H7 serotype is a worldwide zoonotic pathogen responsible for the majority of severe cases of human EHEC disease. The aim of the present study was to investigate the prevalence of E. coli O157: H7/NM in raw meat samples from two provinces of Iran. During a period from March 2010 to March 2011. Two hundred and ninety five raw meat samples were collected from beef (n= 85), camel, (n= 50), sheep (n= 62), goat (n= 60), and water buffalo (n=38). Fourteen (4.7%) of the 295 samples were positive for E. coli O157. The highest prevalence of E. coli O157 was found in beef samples (8.2%), followed by water buffalo (5.3%), sheep (4.8%), camel (2.0%), and goat (1.7%). Of fourteen E. coli O157 isolates, only one was determined to be serotype O157: H7 while 13 were determined as serotype O157: NM. Of the 14 E. coli O157:H7/NM isolates, one, four, two, and one strains were positive for stx1, stx2, eaeA and ehlyA genes, respectively. The prevalence of this organism varied between seasons with the highest prevalence of E. coli O157 occurring in summer (9.3%). The results of this study showed that beef and water buffalo meat are a significant source for human EHEC E. coli O157:H7/NM infection in Iran. The data reported in this study provides some useful baseline in formation for future research such as molecular or epidemiologic works.

Abdollah Ghasemi Pirbalouti, Ebrahim Rahimi, Sayed Ali Moosavi
Acta agriculturae Slovenica , 2010, DOI: 10.2478/v10014-010-0013-1
Abstract: Listeria monocytogenes is a foodborne pathogen responsible for listeriosis. The inhibitory effect of essential oils (1% v/w) of Thymus daenensis Celak (Lamiaceae), Thymbra spicata L. (Lamiaceae) and Satureja bachtiarica Bunge (Lamiaceae) applied to the surface of chicken frankfurters was determined on L. monocytogenes inoculated at low (103 CFU/g) and high (106 CFU/g) populations and stored for seven and 14 days. The results showed that L. monocytogenes populations increased during seven and 14 days of storage at 4 °C on control frankfurters without essential oil. The application of 1 % essential oil (v/w) of herbs to frankfurter surfaces can significantly reduce (p<0.05) the L. monocytogenes populations as compared to control in two inocula treatments after seven and 14 days of storage at 4 °C.

Asian Journal of Neuroscience , 2014, DOI: 10.1155/2014/753286
Abstract: Background. The relationship between underweight and lumbar spine surgery is still unknown. Aim. To evaluate the effect of underweight versus obesity based on surgical outcome of lumbar disc herniation. Material and Method. In this retrospective study, we evaluated 206 patients (112 male and 94 female) with a mean age of years old (ranged 20–72) who have been surgically treated due to the refractory simple primary L4-L5 disc herniation. We followed them up for a mean period of months (ranged 24–57). We used Body Mass Index (BMI), Oswestry Disability Index (ODI), and Visual Analogue Scale (VAS) for categorization, disability, and pain assessment, respectively. We used Wilcoxon and Mann-Whitney tests for statistics. Results. Surgical discectomy in all weight groups was associated with significant improvement in pain and disability, but intergroup comparison showed these improvements in both underweight and obese groups and they were significantly lower than in normal weight group. Excellent and good satisfaction rate was also somewhat lower in both these ends of weight spectrum, but statistically insignificant. Conclusion. Both obesity and underweight may have adverse prognostic influences on the surgical outcome of lumbar disc herniation, although their impact on subjective satisfaction rate seems to be insignificant. 1. Introduction Obesity with its increased stress on the lumbar spine has a known adverse effect on lumbar intervertebral discs. The relationship between obesity and low back pain (LBP) has been repeatedly discussed previously. Numerous authors emphasized the unfavorable effects of obesity on the spinal column including back pain, facet arthrosis, and degenerative disc disease [1–11]. Albeit, it is worth noting that this relationship is not accepted by all authors [12]. Obesity has also been accused of an increased incidence of postoperative spinal complications, but in appropriately indicated patients, it is certainly associate with satisfactory outcomes [13–16]. Therefore, it is nearly proven that obesity has several adverse effects on the lumbar spine but does this mean that underweight has a protective effect on it? Is underweight associated with better lumbar spinal surgical outcomes? There is still little investigation has been performed to evaluate a possible relationship between underweight and the results of lumbar surgeries. In this study we aimed to evaluate the effect of underweight versus obesity on the surgical outcome of the patients with symptomatic lumbar disc herniation who have undergone operative treatment. 2.

Preana: Game Theory Based Prediction with Reinforcement Learning  [PDF]
Zahra Eftekhari, Shahram Rahimi
Natural Science (NS) , 2014, DOI: 10.4236/ns.2014.613099
Abstract:

In this article, we have developed a game theory based prediction tool, named Preana, based on a promising model developed by Professor Bruce Beuno de Mesquita. The first part of this work is dedicated to exploration of the specifics of Mesquita’s algorithm and reproduction of the factors and features that have not been revealed in literature. In addition, we have developed a learning mechanism to model the players’ reasoning ability when it comes to taking risks. Preana can predict the outcome of any issue with multiple steak-holders who have conflicting interests in economic, business, and political sciences. We have utilized game theory, expected utility theory, Median voter theory, probability distribution and reinforcement learning. We were able to reproduce Mesquita’s reported results and have included two case studies from his publications and compared his results to that of Preana. We have also applied Preana on Irans 2013 presidential election to verify the accuracy of the prediction made by Preana.

Analysis of Rooftop Rainwater Harvesting in Kabul New City: A Case Study for Family Houses and Educational Facilities  [PDF]
Obaidullah Rahimi, Keisuke Murakami
Open Journal of Civil Engineering (OJCE) , 2018, DOI: 10.4236/ojce.2018.82013
Abstract: The Afghan government has planned the project of Kabul New City (KNC) to cope with the rapid growth of Kabul, an existing capital city. Due to climatic and topographical reasons, it is supposed that KNC suffers from a water scarcity problem. This study investigates the feasibility of a rooftop rainwater harvesting system in KNC to relieve the water scarcity problem. An applicability of the rooftop rainwater harvesting system was discussed for several types of residential houses and schools, using 11 years rainfall data. This study also examined the cost-effectiveness of the system by considering the service life of the system. Furthermore, an optimal size of the rainwater storage tank was discussed based on the balance among harvested rainwater volume, non-potable water demand, and cost-effectiveness.
Prophylactic antibiotic for prevention of posttraumatic meningitis after traumatic pneumocephalus: design and rationale of a placebo-controlled randomized multicenter trial [ISRCTN71132784]
Behzad Eftekhar, Mohammad Ghodsi, Azar Hadadi, Mousa Taghipoor, Samira Sigarchi, Vafa Rahimi-Movaghar, Ehsan Kazemzadeh, Babak Esmaeeli, Farideh Nejat, Alireza Yalda, Ebrahim Ketabchi
Trials , 2006, DOI: 10.1186/1745-6215-7-2
Abstract: In this prospective, randomized controlled clinical trial, 200 selected head injury patients with traumatic pneumocephalus are randomly assigned to receive intravenous antibiotics (2 grams Ceftriaxone twice a day), oral antibiotics (Azithromycin) or placebo for at least 7 days after trauma. The patients will be followed for one month posttrauma.The authors hope that this study helps clarifying the effectiveness and indications of antibiotics in prevention of meningitis in traumatic pneumocephalus after head injury and in specific subgroup of these patients.Chemoprophylaxis with antibiotics is both feasible and desirable for prevention of a potentially serious disease when specific groups at risk can be defined and when a safe, effective, and affordable prophylactic agent is available [1]. One of such potentially serious diseases is posttraumatic meningitis. The incidence of posttraumatic meningitis after head trauma ranges from 0.2 to 17.8 per cent and increases significantly in the presence of skull base fracture, pneumocephalus or cerebrospinal fluid (CSF) leak [2,3].Considering the serious complications of the posttraumatic meningitis, the idea of chemoprophylaxis with antibiotics for prevention of posttraumatic meningitis has always been considered rational, but the efficacy of prophylactic antibiotic agents in the setting of posttraumatic CSF leakage is still controversial. The contrasting findings reported by two large studies in which metaanalyses were conducted reflect the general disagreement and lack of sufficient power of the previous studies [4-6].One possible reason for the inability of the previous studies to demonstrate the efficacy of prophylactic antibiotics for prevention of posttraumatic meningitis might have been inconsideration of those subsets of patients with specific risk factors [5].With this concept in mind, the authors tried to clarify those subgroups at risk in two subsequent studies since 1994. In the first study done in our hospital (Gh
Effect of Hot Accumulative Roll Bonding Process on the Mechanical Properties of AA5083  [PDF]
Hassan Sheikh, Ebrahim Paimozd
Open Journal of Metal (OJMetal) , 2011, DOI: 10.4236/ojmetal.2011.11002
Abstract: In this work, accumulative roll bonding (ARB) process as a severe plastic deformation was applied on an AA5083 sheet up to 6 cycles at the temperature of 300℃ and at the strain rate of 50 s­‐1. The results of tensile tests show that the values of the yield stress and the ultimate tensile strength don't change considerably after 4 cycles. Also, transmission electron microscopy (TEM) micrograph confirmed that the microstructure has fine (sub) grains with the size of 200 nm - 400 nm.
