vesicoureteral reflux (vur) is one of the most important causes of urinary tract infection and renal failure in children. it is a potentially self-limited disease. the aim of this study was to evaluate the clinical course and significant factors in children with primary vur. the medical charts of 125 infants and children (27.2 % males, 72.8% females) with all grades of primary vur were retrospe...

Merging National Assessment of Educational Progress and Trends in International Math and Science Study math data, this study examines the extent and sources of variation in value-added academic growth patterns among different nations and U.S. states. Applying hierarchical linear models with an instrumental variable method, the study disentangles age effect and grade effect on growth and account...

fused deposition modeling (fdm) is a filament based rapid prototyping system provides us to manufacture real parts with multiple production-grade materials, such as abs-m30, pc, ppsf and pc-abs blend. fused deposition modeling technology, essentially perform using layer manufacturing process. more complex 3d physical models can be efficiently fabricated without geometric limitation by this tech...

preoperative gleason score (gs) obtained from trans rectal ultra sonography (trus) is the most common grading system to evaluate the appropriate treatment for patients with clinically localized prostate cancer. but this method showed upgraded and downgraded results in comparison to gleason score obtained from radical prostatectomy. the current study aimed to determine clinical or pathological v...

a new system is presented for the generation ofrecombinant bacillus subtilis strains without antibioticmarkers. this system is based on two plasmids constructed in escherichia coli. the first plasmid phm30contains an incomplete hisi gene, the last gene in thehistidine biosynthesis operon of b. subtilis and part ofthe genes yvca and yvcb of unkown function flankinghisi at the 3´-end. the spectin...
