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.

Abstract: rs plana vitrectomy and internal limiting membrane peeling for macular edema secondary to retinal vein occlusion Original Research (3118) Total Article Views Authors: Baharivand N, Hariri A, Javadzadeh A, Heidari E, Sadegi K Published Date August 2011 Volume 2011:5 Pages 1089 - 1093 DOI: http://dx.doi.org/10.2147/OPTH.S23164 Nader Baharivand, Amirhossein Hariri, Alireza Javadzadeh, Ebadollah Heidari, Karim Sadegi Nikookari Eye Hospital, Tabriz University of Medical Sciences, Tabriz, Iran Purpose: To evaluate the effects of vitrectomy and internal limiting membrane peeling for treatment of macular edema secondary to retinal vein occlusion (RVO). Methods: Nine cases of visual loss due to macular edema caused by central retinal vein occlusion or branch retinal vein occlusion underwent pars plana vitrectomy with removal of the preretinal hyaloid, peeling of the internal limiting membrane stained with indocyanine green dye, air–fluid exchange, and postoperative prone positioning. Best-corrected visual acuity (BCVA) and central foveal thickness by optical coherence tomography were measured pre- and postoperatively then compared to assess the outcome of surgery. Results: In all cases intraretinal blood and retinal thickening diminished within 2 months of surgery. Visual acuity improved in all of the central retinal vein occlusion cases and 3/6 branch retinal vein occlusion cases. The decrease in macular thickness was statistically significant (mean postoperative macular thickness 361 ± 61.1 versus mean preoperative macular thickness 563.9 ± 90.0, P = 0.001, t-test). The improvement in BCVA was not statistically significant (mean preoperative BCVA in LogMAR 1.23 ± 0.29 versus mean postoperative BCVA in LogMAR 1.06 ± 0.49, P = 0.09, t-test). Conclusion: In eyes with macular edema secondary to RVO, pars plana vitrectomy with internal limiting membrane peeling can resolve macular edema, but the improvement in BCVA was not statistically significant in this study.

Journal of Cardiovascular and Thoracic Research , 2012,
Abstract: Introduction: Hypertension is the most common medical problem affecting pregnant women during pregnancy contributing to one third of substantial maternal mortality and varieties of fetal and neonatal health problems, while representing health status of a society. This study aimed to investigate the links between a healthy life style and developing hypertension during pregnancy in order to improve healthier behaviors.Methods: In a case-control study from October 2009 to April 2010, physical activity and nutritional practices of two groups of pregnant women (220 in each group) with gestational age of 20 weeks or more, single pregnancy, without any previous medical disorders were compared. Samples in case group had pregnancy induced hypertension. Data were collected using a two-part questionnaire after obtaining informed written consents from mothers before enrollment; later the data were analyzed using the SPSS 13 and Stata software. Results: Women in two groups did not differ regarding their socioeconomic characteristics. There were no significant differences in nutritional practices and level of physical activity in pregnant women of study groups; mean score of physical activity was 54.6±14.8 in test and 57.3±15.0 in control group (P=0.06) and it was 72.9±10.3 and 73.719.5 about nutritional habits in test and control group respectively. Mean pre-pregnancy BMI was higher in case group (P=0.02); these women also had a higher percentage of previous prenatal mortality and history of hypertension.Conclusion: Results state that health during pregnancy is relevant to healthy life style especially preconceptional period; therefore employing proper strategies to improve women knowledge and attitude of the important dimensions of healthy life considering good and healthy diet and active life seem to solve the problem; this needs to unite all health workers to set proper educational programs and courses and support of health policy makers.

Exploring the Catalytic Activity of Zirconia, Zirconia Supported Metals and Metal Oxides for Oxidation of Phenol  [PDF]
Mohammad Sadiq, Mohammad Ilyas
Modern Research in Catalysis (MRC) , 2012, DOI: 10.4236/mrc.2012.12004
Abstract: Catalytic oxidation/degradation of phenol with molecular oxygen in aqueous medium by Zirconia, zirconia supported metals and metal oxides at low temperature were studied in a three necked batch reactor. The catalysts prepared were characterized by modern techniques like XRD, SEM and EDX. The activities of different catalysts for the oxidation of phenol in aqueous medium were found to be in the order; Pt-Pd/ZrO2 > Bi-Pt/ZrO2 > Bi-Pd/ZrO2> Pt/ZrO2 > Pd/ZrO2 > Cu/ZrO2> Mn/ZrO2 > Bi/ZrO2. The enhanced catalytic activity of Bi-Pt/ZrO2 is attributed to Bi which in contact with Pt particles promotes its catalytic activity. In short, catalytic oxidation was found to be an effective tool, for the removal of phenol, from industrial waste water.
Glanular Anterior Urethral Valve; A Case Report of an Unusual Cause of Neonatal Urinary Retention  [PDF]
Mohammad Aminu Mohammad
Open Journal of Pediatrics (OJPed) , 2016, DOI: 10.4236/ojped.2016.62025
Abstract: Anterior urethral valve is an uncommon abnormality whose etiology is uncertain, unlike in the case of posterior urethral valve. Glanular anterior urethral valve is even rarer. We present an unusual case of anterior urethral valve, which presented with acute urinary retention and was successfully managed with excision and glans reconstruction. A history of poor stream and dribbling, recurrent urinary tract infections and palpable penile or peno-scrotal mass strongly points to the diagnosis of anterior urethral valve. A voiding cystourethrogramme confirms the diagnosis. It can cause early proximal urinary tract damage and renal failure if not intervened in time. Early surgical intervention will prevent the onset of uremia. Transurethral resection is the treatment of choice.

International Journal of Pharmacology , 2007,
Abstract: Different additives have been used to prolong spinal anesthesia. We designed a prospective, randomized, double-blind study to evaluate the effect of spinal anesthesia. Eighty patients scheduled for first cesarean surgery were randomly allocated into 2 groups to receive either 1.5 mL lidocaine 5% with 0.5 mL sterile water (control group, n = 40) or 1.5 mL lidocaine 5% with 0.5 mL preservative-free magnesium sulfate 10% (magnesium group, n = 40). Neither epinephrine nor opioid was added to the treatment mixture. The duration of analgesia after spinal anesthesia (the time from local anesthetic injection to the first opioid request) and the duration of analgesia after surgery (the time between termination of the procedure and the time at which the first dose opioid was requested) were compared. The durations of analgesia after spinal anesthesia was significantly longer in the magnesium (160.8±49.1) than in the control group (113.3±27.3) and the durations of analgesia after surgery was significantly longer in the magnesium (74.5±47.5) than in the control group (26.6±25.1), (p = 0.001). There was no associated increase in adverse events in the group receiving intrathecal magnesium.
Pectin-Based Biodegradable Hydrogels with Potential Biomedical Applications as Drug Delivery Systems  [PDF]
Mohammad Sadeghi
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2011, DOI: 10.4236/jbnb.2011.21005
Abstract: In this work, synthesis and swelling behavior of a superabsorbent hydrogel based on Pectin (Pc) and polyacrylonitrile (PAN) were investigated. A mechanism for hydrogel formation was proposed and the structure of the product was es-tablished using FTIR spectroscopy. The Pc-poly (sodium acrylate-co-acrylamide) hydrogel exhibited a pH-responsive swelling-deswelling behavior at pH’s 2 and 8. This on-off switching behavior provides the hydrogel with the potential to control delivery of bioactive agents. Release profiles of ibuprofen (IBU), a poor water-soluble drug, from the hydro-gels were studied under both simulated gastric and intestinal pH conditions.
Context-Dependent Data Envelopment Analysis with Interval Data  [PDF]
Mohammad Izadikhah
American Journal of Computational Mathematics (AJCM) , 2011, DOI: 10.4236/ajcm.2011.14031
Abstract: Data envelopment analysis (DEA) is a non-parametric method for evaluating the relative efficiency of decision making units (DMUs) on the basis of multiple inputs and outputs. The context-dependent DEA is introduced to measure the relative attractiveness of a particular DMU when compared to others. In real-world situation, because of incomplete or non-obtainable information, the data (Input and Output) are often not so deterministic, therefore they usually are imprecise data such as interval data, hence the DEA models becomes a nonlinear programming problem and is called imprecise DEA (IDEA). In this paper the context-dependent DEA models for DMUs with interval data is extended. First, we consider each DMU (which has interval data) as two DMUs (which have exact data) and then, by solving some DEA models, we can find intervals for attractiveness degree of those DMUs. Finally, some numerical experiment is used to illustrate the proposed approach at the end of paper.
