The aim of this study was to analyze our experience on patients with a diagnosis of PUV. Materials and Methods: In this prospective study neonates with a diagnosis of PUV were enrolled. The patients were assessed clinically for growth and hypertension and other clinical complaints specially voiding dysfunctions. Urinary tract ultrasonography study, functional renal scan, and voiding cystourethrography performed periodically. The patients were assessed for occurrence of hypertension, growth disturbances, long term urinary tract dilatation, persistence of vesicoureteral reflux (VUR), recurrent urinary tract infection (UTI), nephrolithiasis, voiding dysfunction, scar formation chronic renal failure (CRF) and finally death. Results: A total of 24 children with PUV were enrolled, 18 (75%) had VUR. The mean standard deviation score for height to age was &minus;0.10. Hydronephrosis was persisted in 22 (86%) of patients. VUR was resolved in 9 (56%). UTI was found in follow-up of 15 patients, 10 of them had recurrent episodes. Nephrolithiasis was found in 8 (33%), persistent renal damage in 14 (70%) and CRF in 9 (37.5%) of patients, 5 of them had end-stage renal disease. Voiding dysfunction was observed in 5 (36%) of patients, enuresis in 3 (21%) of them. Two patients were died in the course of disease. Conclusion: PUV is an important obstructive process with potential long-term complication with the need to assess the patients for long periods of time.}, Keywords = {Posterior urethral valve, Hydronephrosis, Urinary tract infection, Scar}, volume = {3}, Number = {2}, pages = {1-6}, publisher = {Mazandaran University of Medical Sciences}, doi = {10.7508/ijhs.2015.02.001}, url = {http://jhs.mazums.ac.ir/article-1-277-en.html}, eprint = {http://jhs.mazums.ac.ir/article-1-277-en.pdf}, journal = {Iranian Journal of Health Sciences}, issn = {2322-553X}, eissn = {2322-4797}, year = {2015} } @article{ author = {Zazouli, Mohammad Ali and Moradi, Ebrahim}, title = {Adsorption Acid Red18 Dye Using Sargassum Glaucescens Biomass from Aqueous Solutions}, abstract ={Background and purpose: Dyes are one of the main pollutants in the various industrial wastewaters. Therefore, the aim of this study was to assess the biosorption of acid red 18 dyes from aqueous solutions by brown macroalgae biomass “Sargassum glaucescens.” Materials and Methods: This research was a lab study. S. glaucescens was used as an adsorbent to remove acid red 18. The effect of various parameters such as pH, initial dyes concentration, adsorbent dose and equilibrium contact time were evaluated in batch adsorption. The dye concentration was measured in the wavelength of 506 nm by spectrophotometer. Results: The results showed that the equilibrium time of biosorption was 120 min. Increasing of contact time and adsorbent dose and initial dye concentration can lead to increasing of the removal efficiency. The maximum adsorption capacity of the dye was at pH: 6 respectively. It was found that the data fitted to Freundlich better than Langmuir isotherms of adsorption model. Conclusion: The S. glaucescens biomass had a satisfactory quality in dye adsorption.

Many occupational diseases are preventable by personal protective devices (PPDs). Though many workers do not use PPDs or their protection by PPDs is not sufficient. This study was designed to assess the quality of PPDs usage among industrial workers. Materials and Methods: In a cross-sectional study, 648 workers from four main industries (tile and ceramic, metal, textile, and chemical) were evaluated for PPDs use. The quality of appropriate PPDs was defined according to the workplace exposures, available PPDs, and time of exposure. The reasons for non-usage of PPDs were evaluated as well. Data were analyzed by SPSS using chi-square test. Results: On average, 56.8%, 69.6%, and 61.6% of workers were exposed to noise, and respiratory and dermal exposures, respectively. From the workers who needed PPDs, 77.8%, 26.3%, and 21% used gloves, respirators and hearing protection devices, respectively. The most frequent reason for non-usage was discomfort while wearing PPDs.

Heavy metal ions pose adverse toxic risks to human health at very low concentrations. The aim of this paper is the adsorption potential of chitosan (CS) in the removal of Hg(II) and Cd(II) ions from aqueous solution. Materials and Methods: This study was conducted in laboratory scale. In this research, CS was used as an adsorbent for the removal of Hg(II) and Cd(II) from aqueous solutions. In batch tests, the effects of various parameters such as metals concentration (40-350 mg/L), pH solution (2-8), contact time (5-120 min), and adsorbent dose (0.25-2 g) were investigated. Results: The results showed that adsorption of Hg(II) and Cd(II) ions on CS strongly depends on pH. The experimental data were analyzed using the Langmuir and Freundlich isotherm models. Equilibrium data fitted well with the Langmuir model and the maximum adsorption capacity of the CS for Hg(II) and Cd(II) were 52.63 and 58.8 mg/g, respectively. Kinetic analysis showed that adsorption was most accurately represented by a pseudo-second-order model.

Materials and Methods: In a semi-experimental design, 21 females with Type 2 diabetes (age: 43 ± 4.92 years and body mass index 29.57 ± 4.17) voluntary participated in study and randomly divided into three: Aerobic exercise, combined exercise and control groups. Aerobic exercise was conducted for 45 min running on the treadmill at 60-70% of maximum heart rate. Combined exercise was conducted for 20 min of running like aerobic group and 10 the stationary resistance exercise for 3 sets of 10 reps. The control group did not perform any exercises. Variables were measured in four stages: Pre-exercise, immediately, 24 and 48 h after exercise at the same time after overnight fasting. Repeated measures ANOVA was used to determine changes within group. Results: The results showed that exercises created significant changes in a triglyceride. In an aerobic group, triglyceride decreased 24 h after exercise compare to before it and in the combined group, increased 48 h after exercise compare to 24 h after it (P ≤ 0.05). Significant changes in low density lipoprotein-cholesterol and high density lipoprotein-cholesterol rate was not observed within two groups (P ˃ 0.05).
