Journal of Science and Technology of Agriculture and Natural Resources , 2008,
Abstract: This experiment was conducted to evaluate the effects of 7 experimental diets (2 diets containing 100 and 200 mg vitamin E (VE)/kg and 5 diets containing 0, 0.5, 1, 1.5 and 2% green tea powder (GTP) ) on performance and breast and thigh meat oxidative stability of broiler chicks during different storage times. A total of 364 male broiler chicks were divided to 28 groups of 13 chicks each. Then every 4 groups were randomly allocated to one of experimental diets. During the experimental period (7-42 days of age) feed intake, weight gain and feed conversion of the experimental groups were measured. On day 42, 2 birds from each replicate (8 chicks per treatment) were weighed, slaughtered and their muscles of breast and thigh were minced and stored at 4oC. Meat oxidative stability of the samples was determined on days 0, 6 and 9 of storage time using thiobarbituric acid test (TBA test). The results showed that addition of the VE and GTP to diets tended to significantly (P

Qom University of Medical Sciences Journal , 2011,
Abstract: Background and Objectives: Nasal congestion is a problem in which many person with migraine headache are involved and can induce misdiagnosis in these patients. Many of these patients with nasal congestion believe that the cause of their headache is due to the sinusitis. The purpose of this study was to determine the frequency of nasal congestion in episodes of migraine headache.Methods: This was a cross-sectional and descriptive study on 131 patients which were diagnosed by neurologists based on standard criteria to have had migraine. Sampling was done through non-probability in hand method. The data were gathered with regard to age, sex, type of headache and presence of nasal congestion for each patient. They were then analyzed by chi-square and Fisher’s exact test (p<0/05)Results: Out of 131 patients 18 (13.7%) had nasal congestion in their migraine attacks. 19.8% of patients were male and 80.2 patients were female. There was no meaningful correlation between nasal congestion in migraine patients with their sex, age and type of headache.Conclusion: According to the results of the study there was no meaningful correlation between the type of migraine headache (classic and non-classic) and sex and age .

Acta Medica Iranica , 2001,
Abstract: The results of standard and augmented surgical treatment of partial accommodative esotropia have been compared in this study.In this sequential matched randomized double blind clinical trial, we studied 48 patients (96 eyes) with partial accommodative esotropia between the ages of 13 to to 144 months, referring to strabismus clinic of Farabi Eye Hospital between 1999-2000. These patients were grouped according to age degree of hyperopia and AC/A ratio and then were randomly divided in two standard and augmented groups (24 patients in each group). All patients were followed for at least 6 months after standard or augmented biomedial recession with or without inferior oblique weakening procedure. Post operative visual acuity, hyperopia, eye deviation, stereopsis, fusion and AC/A ratio were compared between the two groups Post operative acceptable deviation was observed in 37.5% and 87.5% at first week follow up P<0.001). 66.6% and 91.5% at 6 th week of follow up (P<0.05), 91.6% and 95% at 6 th month of follow up (not significant [N.S]) of patients in standard and augmented groups respectively.Other results of standard and augmented groups are as follow:-Improvement of visual acuity (at least one line) in 8.3% and 20.5% (N.S). -Improvement of fusion in 8 out of 13 patients (61.5%) and in 9 of 14 patients (64.3%) (N.S).-Reduction of post operative hyperopia in 3 Patients (12.5%) & 6 patients (25%) (N.S).-Reduction of AC/A ratio in all patients with high AC/A ratio, in both groups.-Improvement of stereopsis in 2 of 13 patients (15.4%) and in 3 of 13 patients (23%) (N.S).this study shows that augmented surgery improves longterm alignment, visual acuity, stereopsis and fusion greater than the standard group, but with statistically insigificant difference, which might be due to short duration of followr up and the small number of cases in each group.

Management Science Letters , 2012,
Abstract: Every day in workplaces, continues events occur that cause death and injury. These accidents usually happen because of lack of exploring the potential hazards and lack of training of employees. Hence, with exploring and evaluating the hazards of workplace and utilizing the suitable procedures, it is possible to prevent from many of these hazardous incidents. Exploring, evaluating and controlling the potential hazards have been the initial stages of scientific safety assurance in every system. Preliminary hazard analyzing is the first effort in analyzing hazards. In this method, usual hazards in sighted job are explored, using the usual hazards table for developing the basis of PHA, the PHA checklist is prepared and at last the PHA table completed and the appropriate suggestions are given. In this paper, we present an implementation of PHA method in one of industries located in city of Tehran, Iran. The proposed study uses 15 explored hazards, where 2 are unacceptable, 9 are undesirable and 4 are acceptable with need of revisal. By eliminating and reducing each hazards risk, some controlling solutions are suggested. The most important of these solutions are utilizing and using the regulations of the welding with electrical archer.

Abstract: Introduction: Dracocephalum polychaetum bornum is exclusively found in a limited geographical area in the Kerman province; It is used by the local people for treatment of abdominal pain, meteorism and musculoskeletal pain. No study has been performed on the effects of D. polychaetum bornum, so the aim of this work was to assess the role of the extract and essential oil of this plant on pain and anxiety assessed by formalin test and elevated plus-maze (EPM), respectively, in male rats. Methods: Analgesic effects: One hundred twelve NMRI male rats were divided into 14 groups. Aqueous extract and essential oil were administered to 8 groups at doses of 25, 50, 100 and 200 mg/kg i.p., while 2 groups were treated with normal saline, and the last 4 groups (sham positive) received ASA (300 mg/kg) and morphine (2.5 mg/kg). Anxiolytic effect: Forty-two NMRI male rats were divided into 7 groups. Four groups were injected intraperitoneally with 25, 50, 100 and 200 mg/kg of the extract of the plant and 2 groups were injected with normal saline (control group) and 1 mg/kg diazepam (positive sham). Anxiolytic effect was evaluated by EPM. Results: The results showed that the extract but not the essential oil at the dose of 200 mg/kg had a significant analgesic effect 25, 30 and 35 minutes after administration. The findings on the anxiolytic effect revealed that there was no significant difference between groups treated with different doses. Conclusion: This study showed that D. polychaetum bornum had analgesic effects.

Audiology , 2012,
Abstract: Background and Aim: Due to defects of auditory feedback, children with hearing loss have inappropriate speech intonation. Consistently, results of previous studies have shown that cochlear-implanted children have some difficulties in their intonation. Intonation shows the type of the sentence which can be statement or question sentences. The purpose of this study was comparison of speech intonation in cochlear-implanted children and normal hearing children.Methods: The present study was performed on 25 cochlear-implanted children and 50 normal hearing children. Different pictures were shown to the subjects and they said statement and question sentences. All sentences were heard by eight speech therapists and perceptually judged. Using praat software mean base frequency and pitch alterations were measured.Results: In cochlear-implanted group, mean speech base frequency was higher and mean pitch alteration was lower than the control group. Mean experts' scores in cochlear-implanted group were lower than the control group. Differences in all three variables were statistically significant (p<0.05). There was a significant direct correlation between duration of time that the children had cochlear implant and perceptual judgment scores (p<0.05).Conclusion: According to the results, cochlear implant prosthesis has limited efficacy in improving speech intonation; although their ability to produce speech intonation improves by increasing duration of the time that children have cochlear implant. Thus speech therapists should consider intervening on speech intonation in treatment program of cochlear-implanted children.

Abstract: Background and aim: Intonation perception mainly relies on fundamental frequency changes perception that is not available for individual with profound to severe hearing loss. The aim of the present study is to investigate the perception of intonation in cochlear implanted children and compare with normal hearing children. Materials and methods: This study has been carried out on 25 cochlear implanted children and 50 children with normal hearing. An adult who her first language was Persian, expressed some questions and statement sentences. These sentences were playing for child and was asked him/her to determine whether it was in a question form or statement one.Results: The results showed that perception of question and statement sentences intonation had significantly differences between two groups (P<0.05). Perception of question and statement sentences intonation had significantly correlation with age at implantation and duration of implant use (P<0.05). Conclusion: According to the findings of the current study and previous studies, cochlear implant has some deficits in facilitating the perception of intonation. However, this limitation has been compensated partly for early surgery. Thus, speech language pathologists should consider intervention of intonation in treatment program of cochlear implanted children.

Abstract: Network theory and its associated techniques has tremendous impact in various discipline and research, from computer, engineering, architecture, humanities, social science to system biology. However in recent years epidemiology can be said to utilizes these potentials of network theory more than any other discipline. Graph which has been considered as the processor in network theory has a close relationship with epidemiology that dated as far back as early 1900 [1]. This is because the earliest models of infectious disease transfer were in a form of compartment which defines a graph even though adequate knowledge of mathematical computation and mechanistic behavior is scarce. This paper introduces a new type of disease propagation on network utilizing the potentials of neutrosophic algebraic group structures and graph theory.

Abstract: A comparative research has been developed for acidity and stability constants of M(Glu)1, M(Asp)2 and M(Ttr)3 complexes, which have been determined by potentiometric pH titration. Depending on metal ion-binding properties, vital differences in building complex were observed. The present study indicates that in M(Ttr) com-plexes, metal ions are arranged to the carboxyl groups, but in M(Glu) and M(Asp), some metal ions are able to build chelate over amine groups. The results mentioned-above demonstrate that for some M(Glu) and M(Asp) complexes, the stability constants are also largely determined by the affinity of metal ions for amine group. This leads to a kind of selectivity of metal ions, and transfers them through building complexes accompanied with glutamate and aspartate. For heavy metal ions, this building complex helps the absorption and filtration of the blood plasma, and consequently, the excursion of heavy metal ions takes place. This is an important method in micro-dialysis. In this study the different as-pects of stabilization of metal ion complexes regarding to Irving-Williams sequence have been investigated.
