Comparison in Effect of Intravenous Alfentanil and Lidocaine on Airway-Circulatory Reflexes during Extubation
Mustafa Sadegi,Abolfazl Firozian,Mohammad Hossein Ghafari,Fatemeh Esfehani
International Journal of Pharmacology , 2008,
Abstract: This randomized controlled double-blind trial was designed to compare the presence of Airway-Circulatory Reflexes to tracheal extubation in groups administering IV alfentanil or lidocaine, in 150 patients undergoing cesarean surgery receiving a standardized anesthetic protocol. At the end of surgery, after return of spontaneous ventilation, patients received either alfentanil 15 μg kg-1 or lidocaine 1.5 mg kg-1. The presence of cough and it`s severity during emergence before extubation was noted. BP and HR were recorded at 2 min after end of surgery (baseline), 2 min after study drug administration and 1 min after extubation. The groups were matched according to age, baseline BP and HR. The incidence of coughing was less frequent in the alfentanil than in the lidocaine group (19% versus 75%, respectively, p<0.001). Although the severity of coughing was considerably different between two groups (lower in alfentanil g) but was not statistically different (p = 0.292). The mean BP and HR were lower in alfentanil than lidocaine group 2 min after administration and 1 min after extubation (p<0.001). The median of delay time (time between the study drug administration and extubation) was 6 min in alfentanil (Range: 4-8) and 5 min in lidocaine groups (Range: 4-8) (p<0.001). These results indicate that alfentanil decreases Airway-Circulatory Reflexes more than lidocaine during emergence from anesthesia without clinically important prolonging the time to extubation.
Comparison of the size of artificial aortic valve with ring diameter by echocardiography
Rangbarnegad II,Esfehani
Tehran University Medical Journal , 1997,
Abstract: In recent socio-economic state it is not possible to have different sets of prosthetic cardiac valves available in the operating room before open-heart surgery for valvular replacement. In this study the diameter of the aortic valve ring measured in 2-D echocardiography was compared with the size of the aortic prosthetic valves implanted for the patients with aortic valvular disease. The purpose was to find a logical correlation to help the surgeons to order the correct size of aortic prosthetic valve in advance of surgery. 26 patients with aortic valve disease were studied from 1972 till 1974 who underwent aortic valve replacement surgery. Now, it is possible to predict the accurate size of aortic mechanical valve prosthesis before surgery

Iranian Journal of Child Neurology , 2007,
Abstract: Objective To study the clinical presentation, hospital course and outcomes of patients admitted with Guillain-Barre Syndrome (GBS) to three tertiary care hospitals in Mashhad, Iran.Materials and MethodsThe records of all patients admitted with flaccid paralysis between April 1999and January 2005 were reviewed and those with the diagnosis of GBS were included in the study. Standard questionnaires were used to record clinical data on was recorded on a standardized questionnaire, which included patients’ age, sex, antecedent infectious history, neurological signs and symptoms and ventilation requirements. The hospital course, including therapy given and the functional status of patients, was analyzed, including therapy given and the functional status of patients.ResultsNinety-one cases of acute flaccid paralysis were admitted to the hospitals during the study period. Eighty-three cases, age range 10 months to 11 years, were later diagnosed as GBS afterwards, with an age range of 10 months to 11 years. The mean age for disease onset was 4.2 years; there were 47 boys and 34 girls, male to female ratio 1:0.7. Upper respiratory tract infection (62.6%) was the most common antecedent event, followed by gastrointestinal infections (19%), urinary tract infection (1.2%) and chicken pox (2.4%), while the remaining cases (14.8%) had no other cases (14.8%) did not have any reliable history of any preceding antecedent infections. Most patients developed GBS within one month of the preceding infection. Cranial nerve abnormalities (19.3%), autonomic dysfunction (7.2%) and respiratory failure requiring intubation (10.8%) were also common. The in-patient mortality was 2.4% (2 of 83).ConclusionGBS was found to occur slightly more often in male patients, majority of whom had histories of previous infection. Despite persistent disability, in-hospital mortality was low.

Soheila Zarringhalami, Mohammad Ali Sahari, Mohsen Barzegar, Zohreh Hamidi-Esfehani
Food and Nutrition Sciences (FNS) , 2012, DOI: 10.4236/fns.2012.32027
Abstract: Production of cocoa butter replacer (CBR) from tea seed oil through common modification methods of oils (dry fractionation, partial hydrogenation, chemical and enzymatic interesterification) was evaluated. Some physico-chemical properties (iodine, saponification, acid and peroxide values) and fatty acid composition (FAC) of modified samples were analyzed and compared with a reference cocoa butter (CB). Solid and liquid fractions for large amounts of unsaturated fatty acids (approx. 80%) and thereby lower iodine values (81 - 85 gI2/100g) than that of CB (37% and 34 gI2/100 g, respectively), are not suitable as CBR. Among all ratios of chemically and enzaymatically interesterified oil blends (20%, 25% and 30% of hydrogenated tea seed oil with 80%, 75% and 70% of tea seed oil/liquid fraction/solid fraction), the samples with ratio of 30:70 from both chemical and enzymatic interesterification had FAC and iodine value closer to that of CB. A comparision between chemically and enzymatically interesterified samples (CISs and EISs, respectively), in terms of solid fat content (SFC) indicated that although the SFC values in EIS were much lower than that of CB, but the thermal behavior of this sample is comprable to CB at 20℃- 30℃ (sharp melting point of CB).

Pakistan Journal of Biological Sciences , 2009,
Abstract: To study the cross interaction of microorganisms in plant growth promotion and the effect of auxin in this interaction, Pseudomonas putida and Glomus intraradices were co-inoculated on wheat. For this purpose, a mutant that produced less amount of auxin was derived from the bacterial strain by chemical mutagenesis with ethyl methane sulfonate. Next both the wild-type strain and the mutant strain were labeled with gusA for a better detection on the roots. Finally, the bacteria were inoculated on wheat as single inoculants or combined with arbuscular mycorrhizal fungi. Controls included non-bacteria/non-arbuscular mycorrhizal fungi and arbuscular mycorrhizal fungi alone. Plants co-inoculated with the wild-type bacterial strain and Glomus intraradices had the highest stem and their fresh and dry shoot weight was more than other treatments. Also, it was observed that the wild-type strain significantly improved the mycorrhizal colonization which implies the beneficial effect of auxin on mycorrhizal colonization. Furthermore, Glomus intraradices increased the population density of the wild-type strain in the endorhizosphere. In the microscopic studies of plant roots, bacterial colonies were observed as blues lines on the surface and inside the roots as well as on the seed surfaces.

F. Ansari,M. Sedehi Esfehani,A. Djazayery
Pakistan Journal of Nutrition , 2008,
Abstract: Energy, protein and iron intakes and status were investigated in 471 married women, 20-56 years old, selected by 2-stage random sampling, in rural areas in Islamic Republic of Iran. Pre-tested 24-hour dietary recall questionnaire was used to get data on nutrition intakes. Although average total iron intake was acceptable, only 6.4% of women derived at least 4% of their total intake from animal iron. Average energy and protein intakes were inadequate. Fining of this study showed that this group with medium-to-low socioeconomic status should receive particular attention in national health and nutrition planning.
Computer-Assisted analysis of subcellular localization signals and post-translational modifications of human prion proteins  [PDF]
Fatemeh Moosawi, Hassan Mohabatkar
Journal of Biomedical Science and Engineering (JBiSE) , 2009, DOI: 10.4236/jbise.2009.21012
Abstract: In the present work, computational analyses were applied to study the subcellular localiza-tion and posttranslational modifications of hu-man prion proteins (PrPs). The tentative location of prion protein was determined to be in the nu-cleolus inside the nucleus by the following bio-informatics tools: Hum-PLoc, Euk-PLoc and Nuc-PLoc. Based on our results signal peptides with average of 22 base pairs in N-terminal were identified in human PrPs. This theoretical study demonstrates that PrP is post-translationally modified by: 1) attachment of two N-linked complex carbohydrate moieties (N181 and N197), 2) attachmet of glycosylphosphatidylinositol (GPI) at serine 230 and 3) formation of two di-sulfide bonds between “6–22” and “179–214” cysteines. Furthermore, ten protein kinase phosphorylation sites were predicted in human PrP. The above-noted phosphorylation was car-ried out by PKC and CK2. By using bioinfor-matics tools, we have shown that computation-ally human PrPs locate particularly into the nu-cleolus.

Abstract: Bacterial pathogens and drug resistance are different in hospitals of each country. In this study we determined bacterial path- ogens and drug sensitivity in the neonatal ward and neonatal intensive care unit (NICU) in Ekbatan hospital in Hamedan. This cross-sectional descriptive study was done on 1150 hospitalized neonates in neonatal and NICU wards of Ekbatan hospital of the Hamadan university of medical sciences from September 2004 to September 2006. Blood, cerebrospinal fluid (CSF), urine, stool, eye excretion, synovial fluid, umbilical secretion and ascitic fluid were evaluated. Positive cultures were evaluated for antibiotic resistance with disk diffusion test methed. All of the data in questionnaires was analyzed with SPSS 13. Cultures including blood, urine, CSF , stool, eye excretion, synovial fluid, umbilical secretion and ascitic fluid was done in 417 neonates (833 cultures). These cultures were including: urine, 323 cases (38.8%) blood 293 cases (35.2%), CSF 180 cases (21.6%) , stool 17 cases (2%), eye secretion 16 cases (1.9%) and other secretions (synovial, umbilical, etc) 4 cases (0.5%). The cultures were positive in 105 cases (25.2%). 60 male neonates (57.1%) and 45 female neonates (42.9%) were culture positive. The most common microorganisms were E coli 66.7% (70 cases), Klebsiella 10.5% (11 cases). Drug resistance was high in these microorganisms. The most common microorganisms were Ecoli and klebsiella. Drug resistance was high in the isolated microorganisms.

Health (Health) , 2010, DOI: 10.4236/health.2010.25074
Abstract: The rate of dental caries and periodontal diseases in the world is still high, regardless of progress in the oral and dental hygiene. The natural toothbrush or chewing stick called “Mis- wak” has been used since ancient history. In this research the efficacy of Miswak in preventing dental caries was investigated and compared with the efficacy of toothbrush and tooth- paste. The analytical and clinical trial method was applied for this research among high sch- ool’s students in the city of Yazd, Iran, 2006. Three hundred eighty second year’s students (190 cases and 190 controls) were examined dentally. Then the Miswak was distributed to the case group and required trainings were given to both groups. After one year, the examinations were repeated. For analyzing the data one-way variance analysis test, Kai square, Paired t-test and two variable analyses were used. In the beginning of this study, there were no significant differences between two groups (cases and controls) regarding their dental situation and the frequency of brushing their teeth (p-value = 0.162). In addition, there were no significant differences in DMFT between the two groups. The data collected at the end of the study showed a significant increase in DMFT in the control group (p-value = 0.000). There was 55% increase in the rate of dental caries in control group compared to case group (0.89 before the study and 1.38 after the study). The risk of dental caries for each tooth in control group was 9.35 times more than case group (9.14% and 0.98% respectively). Dental caries rate was detected slightly less in the case group at the end of this study. This might be as a result of the antimicrobial effects of Miswak. A longer study with more cases is needed to prove this suggestion.
