Results of Modified Gil-Vernet Antireflux Surgery in the Treatment of Vesicoureteral Reflux
Darioush Irani,M Heidari
Urology Journal , 2004,
Abstract: Purpose: To evaluate the efficacy of modified Gil-Vernet anti-reflux surgery in the treatment of patients with primary vesicoureteral reflux in a prospective historical controlled trial. Materials and Methods: A total of 30 patients with 46 refluxing units underwent this surgery since February 1998 until September 2002, with the mean follow-up period of 18 (range 6 to 43) months. Results: Vesicoureteral reflux was resolved completely in 44 ureteral units (95.6%, P < 0001). In 2 refluxing units (4.3%) in spite of reflux improvement, hydroureter remained unchanged after the surgery. In respect to response rate, there was no significant difference between different grades, genders, age groups, and laterality of primary vesicoureteral reflux. Conclusion: Our findings indicate that modified Gil-Vernet anti-reflux surgery which separately transfers each ureteral orifice to the tip of trigone with two fine absorbable suture on each side, is a completely successful procedure in the treatment of primary vesicoureteral reflux and produces a longer submucosal tunnel with a more suitable angel than classic Gil-Vernet procedure dose.

Abstract: Reaction modeling of SMR (Steam Methane Reforming) process inside monolith reactors using two approaches were investigated and compared with each other. In the first approach, the reactions were assumed to take place exactly on the wall surfaces, while in the second approach they considered inside a thin thickness near the walls. Experiments of SMR were carried out in a lab-scale monolith reactor. A single-channel was considered and CFD model were developed for each of aforementioned approaches. Comparisons between modeling results and experimental data showed that the first approach (surface model) gives better results. Performing reactions are difficult and expensive, CFD simulations are considered as numerical experiments in many cases. It was concluded that obtained results from CFD analysis gives precise guidelines for further studies on optimization of SMR monolithic reactor performance.

Abstract: the effect of cinnamon powder (cnp) feeding on some blood metabolites in broiler chicks was studied in a 49-day experiment. the feeding program consisted of a starter diet until day 21, a grower diet until day 42 and a finisher diet until day 49. there were five treatments: a negative control diet, without the additive (control: t1); 250 mg/kg (t2); 500 mg/kg (t3); 1000 mg/kg (t4); and 2000 mg/kg (t5) of cnp in the diet. a total of 320 one-day-old mixed-sex broilers (ross 308) were distributed into 16 pens with 20 chickens each, comprising 3 replicates per treatment (except for t1, which had 4 replicates). serum glucose was measured weekly and reported periodically. at the end of the experiment serum cholesterol, triglycerides, aspartate aminotransferase (ast) and alanine aminotransferase (alt) activities were determined. there were no significant differences among treatments regarding broiler performance and carcass characteristics, except for the finisher phase, when t2 resulted in a significant decrease in feed conversion ratio and weight gain (p<0.05). in the lowest level of cinnamon supplementation (t2), a significant increase in glucose level in starter, finisher and overall rearing period was observed, as well as an increase in triglyceride levels at the finisher phase as compared to t4 and t5 (p<0/05). however, cholesterol, ast and alt levels were not statistically different among treatments. therefore, it was concluded that the use of cinnamon powder can affect on some blood metabolites and broiler performance.

Abstract: The objective of this study was to investigate the effects of four dietary levels of L-threonine (0, 2.5, 5 and 7.5 g/kg) with or without Saccharomyces cerevisiae (SC) on performance, carcass characteristics, intestinal morphology and immune system of broiler chickens. A total of 360 1-d-old male broiler chicks were randomly allocated to eight treatments with three replicates of 15 birds. The experiment was done at 0 to 3 weeks (as starter phase) and 3 to 6 weeks (as grower phase). Growth performance traits including weight gain, feed intake and feed conversion ratio were recorded at the end of each week. At the end of the experiment eight birds per treatment were killed and carcass analysis was done. Sampling for blood evaluation was done on 7, 28 and 42 days of age. Results of this study indicated that use of SC did not affect feed intake, weight gain and feed conversion ratio in chicks in contrast with the L-threonine. Use of L-threonine improved feed conversion ratio and gain of birds. Carcass traits were not influenced by dietary L-threonine and SC supplements. Use of L-threonine increased the intestinal morphology parameters such as crypt depth and villi height and width in both jejunum and ileum segments. On the other hand, villi height and width and crypt depth increased in both jejunum and ileum segments when dietary L-threonine increased. Effect of SC supplement on intestinal morphology was not significant. Results of CBC (cell blood counts) parameters, such as white blood cells, red blood cells, haematocrit and haemoglobin showed that these parameters were not affected by dietary treatments. Furthermore, the immune response (antibody titre) against Newcastle disease was not affected by SC on both 26 and 42 days of age. However, use of L-threonine influenced the chicks’ immune response at 42 days of age. Our results have shown that the supplementation of L-threonine as a source of dietary-threonine in combination with SC improved growth performance and intestinal morphology traits in broilers.

Abstract: Purpose: To evaluate the efficacy and safety of intravesical Bacillus Calmette-Gurein injection in the treatment of female patients with interstitial cystitis. Materials and Methods: Thirty women meeting the National Institute of Arthritis, Diabetes, digestive and kidney diseases criteria for interstitial cystitis, were randomized in a double-blinded fashion in two groups each consisted of 15 patients to receive six, weekly instillation of 120 mg BCG vaccine of Iranian Institute of pastor or placebo. Periodic questionnaires on symptoms of interstitial cystitis, voiding diaries, bladder capacity at first desire to void, and maximum bladder capacity were obtained. Adverse events were closely monitored during the treatment and follow-up phases of the study. Subjective and objective baseline values were compared with the follow-up data. Results: With a mean follow-up of 24 (range 6 to 33) months 11 out of 15 (73%) in BCG group, and 3 out of 15 (20%) in placebo group responded to the treatment (P < 0.002). Responders were defined the patients with more than 40% improvement in the symptoms of interstitial cystitis. The global improvement in symptoms and signs of interstitial cystitis was 62%. Adverse events were similar in both groups, mostly irritative in nature and no significant systemic event was noted. BCG did not worsen interstitial cystitis symptoms. Conclusion: We concluded that intravesical BCG is safe, effective, available, and inexpensive with relatively durable results in the treatment of interstitial cystitis.

The most probable cancerous mutations occur as point mutations in exons 5 up to 8 of p53, as a base pair substitution that encompasses CUA and GAT sequences. As DNA drug design represents a direct genetic treatment of cancer, in the research reported computational drug design was carried out to explore, at the Hartree–Fock level, effects of solvents on the thermochemical properties and nuclear magnetic resonance (NMR) shielding tensors of some atoms of CUA involved in the hydrogen-bonding network. The observed NMR shielding variations of the solutes caused by solvent change seemed significant and were attributed to solvent polarity, and solute–solvent and solvent–solute hydrogen-bonding interactions. The results provide a reliable insight into the nature of mutation processes. However, to improve our knowledge of the hydration pattern more rigorous computations of the hydrated complexes are needed.

Abstract: Background: There are conflicting reports about zinc, a trace element, in the pathogenesis of hypertension and other cardiovascular diseases. The aim of this study was to evaluate the role of zinc in high blood pressure.Methods: We conducted this study on 80 patients with primary (idiopathic) hypertension and 80 normotensive people with similar age who attended to Tehran Heart Center between 2007 and 2008. We examined the effect of zinc concentration on blood pressure in both sexes in four age groups (41-50, 51-60, 61-70 and 71-80 years old). We measured plasma zinc concentration by atomic absorption.Results: The mean plasma zinc concentrations were 0.456±0.04 μg/ml and 0.551±0.055 μg/ml in patients with hypertension and in normotensive people, respectively, (P≤0.05). Nevertheless, the mean plasma zinc concentrations were 0.494 μg/ml and 0.486 μg/ml in men with and without hypertension, respectively. The mean plasma zinc concentrations of women with and without hypertension, respectively were 0.415 μg/ml and 0.596 μg/ml, showing a significant difference between two groups (P≤0.001). Moreover, there was a significant difference in plasma zinc concentration between hypertensive and normotensive people in 51 to 60 years age group (P≤0.05), but difference were not significant between other age groups.Conclusion: The results of this study revealed the relationship between the decrease in plasma zinc concentration and increase in blood pressure in women and in the men aged 51 to 60 years.
