A Comparison of Fluoride Uptake by Sound Enamel Following Application of Sodium Fluoride Mouthrinses and APF Gels Produced in Iran with Standardized Foreign Samples
J Mahmoodian,A Kowsari,B Esmaeili
Journal of Dental Medicine , 2002,
Abstract: The goal of this investigation is to compare the extent of fluoride uptake by sound enamel following application of two commercial mouthrinses containing sodium fluoride (0.2%) and a topical gel containing APF (1.23%) produced in Iran with those of foreign standardized ones. Sixty extracted premolars were used. Each tooth was divided into two lingual and buccal halves, one half as control, the other one as experimental. Enamel biopsy technique (two- step acid etching) was used to determine the concentration of fluoride and calcium in each sample. For data comparison and fluoride uptake estimation, the depths of layers with the use of linear regression analysis were standardized to 25 and 50um. The analysis showed that in Iranian mouthrinse no. 1, there is linear correlation between fluoride concentration and enamel depth, in both control and experimental group at the first and second layers, while, in other groups, this correlation was observed just at the first layer (superficial enamel layer). The greatest fluoride uptake was seen at Iranian mouthrinse no.2 and the least was seen at foreign mouthrinse no. 3. From among two APF gels, the greatest uptake was observed at gel no. 1 (Iranian). The results showed that all three Iranian products increase fluoride content of enamel, moreover the level of fluoride uptake, while applying Iranian products, in comparison with foreign ones, shows considerable increase.

Journal of Research in Medical Sciences , 2005,
Abstract: Background: Dry cough is the most common adverse effect and limiting factor of all angiotensin converting-enzyme inhibitors (ACEIs) . Prostaglandins have been pinpointed as playing an important role in the genesis of this problem. This double blind clinical trial desinged to study the efficacy of 500 milligram(mg) of aspirin comparing with placebo in controlling Enalapril-induced cough. Methods: The subjects were 32 patients who had developed Enalapril-induced cough.They were randomized into two groups: a group of daily dose of aspirin, 500 mg and a group of placebo for a treatment period of 4 weeks. Mean of cough severity was compared between two groups before treatment and weekly, until 4 weeks. Results: Mean of cough severity in aspirin and placebo groups before and at the end of first week of treatment did not show any significant difference. After the second ,third, and fourth weeks, cough severity scores were significantly reduced in aspirin group(p<0.001). Conclusion: 500mg aspirin, once daily, can suppress or abolish Enalapril-induced cough and this finding proposes alternative therapeutic approach for ACEIs-induced related cough. Keywords: aspirin, cough, Angiotensin-Converting Enzyme Inhibitors (ACEIs), enalapril

Smart Grid and Renewable Energy (SGRE) , 2012, DOI: 10.4236/sgre.2012.33027
Abstract: Renewable energy systems are of importance as being modular, nature-friendly and domestic. Among renewable energy systems, a great deal of research has been conducted especially on photovoltaic effect, wind energy and fuel cell in the recent years. This paper describes dynamic modeling and simulation results of a small wind-photovoltaic-fuel cell hybrid energy system. The hybrid system consists of a 500 W wind turbine, a photovoltaic, a proton exchange membrane fuel cell (PEMFC), ultracapacitors, an electrolyzer, a boost converter, controllers and a power converter that simulated using MATLAB solver. This kind of hybrid system is completely stand-alone, reliable and has high efficiency. In order to minimize sudden variations in voltage magnitude ultracapacitors are proposed. Power converter and inverter are used to produce ac output power. Dynamics of fuel-cell component such as double layer capacitance are also taken into account. Control scheme of fuel-cell flow controller and voltage regulators are based on PID controllers. Dynamic responses of the system for a step change in the electrical load and wind speed are presented. Results showed that the ability of the system in adapting itself to sudden changes and new conditions. Combination of PV and wind renewable sources is made the advantage of using this system in regions which have higher wind speeds in the seasons that suffers from less sunny days and vice versa.

Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC) , 2018, DOI: 10.4236/jhepgc.2018.44040
Abstract: In this paper, the dynamical behavior of an anisotropic universe in an extended gravity e.g. the f (R,T ) theory of gravity is studied. We use f (R,T ) = R + 2μT , where R is the Ricci scalar, T is the trace of energy-momentum tensor and μ is a constant. Two cosmological models are constructed using the power law expansion and hybrid law cosmology in Bianchi type I universe, where the matter field is considered to be a perfect fluid. It is found that in both the cases the anisotropic behavior is in agreement with the observational results. The state finder diagnostic pair and energy conditions are also calculated and analyzed.

Iranian Journal of Pediatrics , 2006,
Abstract: Background: Impetigo is a common infectious skin disease and most commonly occurs in children. Etiologic agents are Staphylococcus aureus or Beta-heamolytic Streptococcus group A or combination of these organisms. Adequacy of treatment is related on sensitivity of bacteria to common prescribed antibiotics. Methods: Study of the frequency of bacterial culture results from lesions and antibiograms for four systemic antibiotics cephalexin, erythromycin, cloxacillin and penicillin were assayed. Impetigo cases admitted to the dermatology clinic of Ghaem hospital in Mashhad for one year beginning from June 2001, were studied. These patients had no history of systemic or topical antimicrobial agents application. Results of antibiograms obtained from culture of skin lesions were analyzed with Chi-Square test. Findings: Twenty two (88%) patients were younger than 20 years. Twenty one cases (84%) had non bullous impetigo. In 17 (68%) cases lesions were localized on the face. Because of secondary contamination in 3 cases, statistical analysis was performed on 22 cases. The most common bacteria (95.5%) was Staphylococcus aureus. Antibiograms of S.aureus showed complete sensitivity to cephalxin in 85.3%, erythromycin in 63.6%, cloxacillin in 40.9%, and penicillin in 13.6% of cases. Conclusions: Staphylococcus aureus was the most common organism in 95.5% of cases and cephalexin was the first choice oral antibiotic followed by erythromycin.

Abstract: Cutaneous leishmaniasis is endemic in 88 different countries. There are an estimated 1.5 million new cases each year, with over 90% occurring in Afghanistan, Algeria, Iran, Iraq, Saudi Arabia, Syria (Old World) and in Brazil and Peru (New World). Miltefosine is effective in vitro and in vivo against Leishmania species and it was demonstrated efficacy in animals via the oral route. This study is the first one for evaluating the effect of miltefosine on cutaneous leishmaniasis of L. major (MRHO/IR/75/ER) by in vivo and in vitro studies in the BALB/c mouse model. As it was shown, miltefosine has a better effect on reduction of size of lesion compared to Glucantime , also it was not significant by statistical analysis. The results of this study show that miltefosine has a good activity against the proliferation of amastigotes of L. major. The results suggest that oral miltefosine might be a promising approach for developing new anti-Leishmanial drugs.

Abstract: Background and objectivesIodine deficiency was a public health problem in Iran before the start of iodine supplementation program in 1989. This study has been conducted in the framework of the national monitoring survey in 2001 to find the prevalence of goiter and urinary iodine levels in order to evaluate the effect of national supplementation program on the iodine status of school-aged children in the city of Qom. MethodsIn a descriptive, cross-sectional study, 1200 schoolchildren, aged 7-10 years, were selected randomly from all regions of Qom, and the grade of goiter was determined in 600 boys and 600 girls according to WHO classification. Urinary iodine content was estimated using the digestion method in one tenth of the schoolchildren.ResultsGoiter was observed in 26% of children (24.3% of girls and 27.7% of boys). The average urinary iodine level was 15.2 μg/dl. Urinary iodine levels higher than 10 μg/dl was measured in 71.7% and less than 5 μg/dl in 8.1% of children. Urinary iodine levels less than 2 μg/dl has not been observed in any of the cases. No significant difference was observed in prevalence of goiter and the urinary iodine level between males and females, and students in living in urban or rural areas.ConclusionComparison of these results with those of the year 1996 shows that prevalence of goiter has significantly decreased in these students. Also, it shows that in the city of Qom, the urinary iodine levels of schoolchildren fall in the standard range determined by WHO. This indicates that the iodine intake is adequate in the province of Qom. Therefore, this province can be considered as an “iodine deficiency-free” zone.Keywords: Goiter; Goiter Endemic; Iodine.
