Journal of Dental Medicine , 2012,
Abstract: Background and Aims: The oral impact on daily performance (OIDP) is one of the oral health-related quality of life indices to measure physical, social and mental consequences of the oral health status. This study aimed to evaluate the OIDP index in patients referring to Tehran dental school.Materials and Methods: Four hundred and ninety nine patients referring to patients' clinic in Dental School of Tehran University of Medical Sciences in spring 2011 participated in this study. They were interviewed for demographic factors including age, gender and level of education, and OIDP index questionnaire before receiving any treatment. Statistical analysis was carried out by means of linear regression modeling.Results: 85.6% of patients confirmed that they had at least one oral impact on daily performance during the last 6 months. The most prevalent performances affected were eating (50.1%) and smiling and showing teeth without shame (12.8%). The mean OIDP score for the population was 5.6 ranging from 0 to 36. Linear regression modeling controlling for age, gender and years of education revealed that older patients and those with lower education had significantly higher OIDP scores.Conclusion: The effect of oral health on daily performance was clear. The association among age, education and oral impact on daily performance indicates the need for more comprehensive preventive oral health care for adults with lower educational level.

Iranian Endodontic Journal , 2012,
Abstract: Introduction: The success of endodontic retreatment is related to the complete removal of the obturation material from the root canal system. The aim of this study was to evaluate the efficacy of Mtwo R and ProTaper retreatment files in removing the Resilon/Epiphany system with or without chloroform during retreatment. Materials and Methods: Sixty distal roots of first mandibular molars were prepared and laterally condensed with Resilon/Epiphany, then divided into four groups (15 each for retreatment): 1) Mtwo R/solvent; 2) Mtwo R; 3) ProTaper D/solvent; and 4) ProTaper D. The cleanliness of the canal walls was evaluated using radiography; a stereomicroscope and SEM. Data were subjected to ANOVA and Student’s t-test. Results: Neither rotary system performed better than the other when considering the whole root canal, with or without solvent. In the apical portion, ProTaper/solvent showed the best result (P<0.05). Conclusion: In Resilon/Epiphany retreatment cases, ProTaper/solvent was better in the apical portion; however when considering the whole canal, Mtwo R and the ProTaper D series had the same performance.

Abstract: In this paper, the effects of frying time, white egg (0%, 5% and 10% w/w) and chitosan (0%, 0.5% and 1.5% w/w) addition to the batter formulation on the quality of simulated crispy deep-fried Kurdish cheese nugget crusts was studied by using a deep-fried crust model. Moisture content, oil content, color and hardness of the samples were determined. Crust models were fried at 190℃ for 60, 120 and 180 s. Batter formulations and frying time significantly (p < 0.01) affected moisture, oil content, color and hardness of Crust models. Batter formulation contain 10% white egg was found to be an effective ingredient in decreasing oil content of Crust models. The mean moisture and fat content of Crust models formed with batter contained 10% white egg, fried at 190℃, for 180s were 6.207 ± 0.447 and 5.649 ± 0.394. Batters containing 5% white egg and 1.5% chitosan showed the lowest moisture content and the highest oil content among all the formulations. Crust models containing combination of white egg and chitosan were the darkest. Hardness of samples containing chitosan were the highest, specially for ch1.5 The mean hardness in 60, 120 and 180s of frying in this formulation were 21.518 ± 0.481, 36.871 ± 1.758 and 49.563 ± 1.847 respectively.

Amin Eimanifar, Feridon Mohebbi
Aquatic Biosystems , 2007, DOI: 10.1186/1746-1448-3-5
Abstract: Lake Urmia (or Orumiyeh), is one of the largest permanent hypersaline lakes in the world and resembles the Great Salt Lake in the western USA in many respects of morphology, chemistry and sediments [1]. Despite this, and its several values, including conservation, little literature has been published on the lake and its biota[2-7]. The aim of the present paper is to provide a brief review based on previous and recent literature on various aspects of Urmia Lake with particular emphasis on conservation and management. Although we cannot provide an all inclusive coverage here, we hope that it will be sufficient to introduce this remarkable lake to the general reader.Urmia lake can be characterized as oligotrophic in terms of phytoplankton production in the range of 0.5–0.8 μg/l [6], with lower values compared to Great Salt Lake (0.5–3.5 μg/l) [8]. The predominance of the Na+ and Cl- ions illustrates the thalassohaline character of Urmia lake [9]. Therefore, Urmia Lake is an oligotrophic lake of thalassohaline origin [10] located in northwestern Iran at an altitude of 1250 m above sea level [6]. The total surface area ranges between 4750 km2 and 6100 km2 [11] depending on evaporation and water influx. The catchment area of the lake contains 21 permanent and ephemeral streams together with 39 episodic rivers, flowing through agricultural, urban and/or industrial areas that drain into this terminal lake, mostly without waste water treatment [12]. The maximum length and width of the lake are 128–140 km and 50 km, respectively [11,13]. The average and maximum depths are 6 m and 16 m, respectively [14]. The lake is divided into north and south parts separated by a causeway [15], which has a gap that allows for a limited exchange of water between the two arms [14].Considering the role of Artemia in Urmia Lake, the Iranian Fisheries Research Organization (IFRO) established the Artemia Research Center in Urmia in 2000. On the basis of the vital role of Artemia as a live food in

Journal of Dentistry of Tehran University of Medical Sciences , 2004,
Abstract: Statement of Problem: Chondrosarcoma is a tumor which includes 10 percent of the bone primary tumors. Its prevalence is half of the osteosarcoma and two times of Ewing’s. The mean age of the patients ranges between 30-50 years of old. There is no significant sex orrace predilection. The most common complaint is the presence of a painless and enlarging mass. Its clinical course is described as slow-growing lesion with local invasion and recurrence, no or delayed metastasis, almost long survival.Purpose: The aims of this study were as follows: the determination of prevalence of reported Chondrosarcoma in cancer institute Imam Khomeini hospital and faculty of dentistry of Tehran University of medical sciences, comparison of jaw Chondrosarcoma to the body one, evaluation of sex, age, clinical and histological parameters and prevalence of different locations in body.Materials and Methods: In this study the biopsy notes of all kinds of chondrosarcoma of the body in cancer institute (212 cases) and the extracted files of the patients with the jaws chondrosarcoma in cancer institute and department of oral pathology of faculty of dentistry,University of Tehran medical sciences (23 Cases) were evaluated.Results: In this retrospective statistical study the proportion of the patients with the jaws conventional chondrosarcoma to the patients with conventional Chondrosarcoma of the body was 8.57%. The mean age of the total patients and the patients with jaws chondrosarcoma were 36.21 and 38.87 years, respectively. Men were somehow more involved. Pelvic was the most common location of the tumor. Maxilla involvement was 3-4 times more than mandible. Microscopic manifestation and tumor grading suggested a lowgrade lesion in jaws. Local recurrence in jaws was 33.3%.Conclusion: The most common site of involvement of chondrosarcoma was pelvic and maxillary involvement was more common than mandible. Its prevalence was in the posterior site of the jaws.

Iranian Journal of Otorhinolaryngology , 2010,
Abstract: Introduction: Sinusitis is one of the differential diagnosis of asthma. Association of sinusitit with asthma can result in severity of the disease and treatment failure. This study aimed to determine the prevalence of sinusitis in under 12 year old asthmatic children. Material and Methods: In this prospective cross sectional study, the prevalence of sinusitis was determined in 60 under 12 years old asthmatic patients (47 boys, 13 girls) according to clinical signs (headache, productive cough, post nasal discharge, purulent nasal discharge), and the graphy of paranasal sinuses. The data (age, sex, severity of asthma) evaluated in two groups of patients, with sinusitis and without sinusitis. The site of sinusitis and prominent clinical signs were determined in patients with sinusitis. Results: The prevalence of sinusitis was 48.3%. There was no differences in sex distribution between two groups (P=42%). The mean ages were 6.9± 2.2yr in sinusitis group and 6.6±2.0 yr in group without sinusitis. The maxillary sinuses were the most abnormal sinuses in graphy (86.2%). The most prevalent sign was cough (55.17%). There were no differences in type and severity of asthma in the two groups. Conclusion: The prevalence of sinusitis is high in asthmatic patients. In the cases of persistent cough in asthma, sinusitis must be considered. We didn’t find correlation between sinusitis and severity of asthma but it must be considered in the cases of poor control of asthma.

Journal of Lasers in Medical Sciences , 2012,
Abstract: INTRODUCTION: Acne scar is formed after severe episodes of acne in teen and earlyadult years. Several treatment options have been used for depressed acne scars suchas punch grafting, punch excision carbon dioxide (CO2) laser etc. Moreover, Studiesshow that laser skin resurfacing such as CO2 fractional can effectively treat depressedacne scars. We investigated the efficacy of fractional CO2 laser in acne scar. METHODS: In this clinical trial; we used CO2 fractional laser (Unit: eCO2 LutronicKorea; FDA approved) in 15 female cases with an age range of 20-40 years old.They underwent 3 sessions of laser resurfacing at one month intervals. In the first session we used laser with a density of 150 and fluency of 70 with a 4mm diameter circular spot in static mode on depressed acne scars, and we exerted laser with density of 100 and fluency 70 with 12 mm diameter square spot in static mode on all involved skin in the other sessions. Photographs were taken before every process. The patients and another dermatologist filled the questionnaire concerning the percent of improvement. Finally, we compared photographs and evaluated the efficacy of CO2 fractional laser in acne scars. RESULTS: Objective and subjective improvement was estimated about 20-70% and 30-70%, respectively, without any erythema, permanent hyperpigmentation and other adverse effects. The important point is that, participants returned back to work after 4-7 days. CONCLUSION: The Fractional CO2 laser resurfacing can be used as a safe and efficacious method to treat depressed acne scar.

Journal of Human Sport and Exercise , 2011,
Abstract: Introduction: Circadian rhythms regulate some metabolic and hormonal variables that affect fat oxidation rates. Thus, the purpose of this study was to investigate Maximal fat oxidation (MFO) at a different exercise intensity in obese and normal weight men in the morning and evening. Methods: MFO was measured in 12 normal weight (BMI 20-25 kg/m2; VO2max 45.7±3.44 ml/min/kg) and 10 obese (BMI >30 kg/m2; VO2max 37.2±3.6 ml/min/kg) men during incremental running exercise test with 3 min stages on the treadmill by indirect calorimetry method. Student’s t-test and one-way ANOVA with repeated measures were used to analysis variables. Results: We found that fat oxidation rates and energy expenditure in both groups in the evening were higher than morning; there were no significant differences in MFO between obese and normal groups. Furthermore, the fat oxidation rate in low intensity exercise (<60% VO2max) was similar in obese and normal weight groups, but in high exercise intensities, in normal weight men were significantly higher than obese men. Conclusion: Our results suggest that independent of exercise intensity and body fat mass, exercising in the evening is more effective on fat oxidation and decrease body fat mass; therefore, it is better for weight loss purposes in obese and normal weight men.
