the photocatalytic degradation of two anionic azo dyes acid red88 (ar 88) and acid orange 7 (ao7) was investigated in aqueous solution using a tio2-containing hydrogel and uv light. the ph-sensitive hydrogel poly (styrene-alt-maleic anhydride) (psma), was synthesized and crosslinked in the presence of melamine and tio2 nanoparticles which results in entrapment of tio 2 into the melamine-grafted...

As a result of the population aging, incidence both hematologic and non-hematologic diseases elderly gets higher, requiring bone marrow (BM) aspirations biopsies be implemented also in geriatric patients. Our aim this study is to address BM examination patients aged 85 over, describing its indications morbidity discussing established diagnoses outcomes applied therapies based on examinations co...

in this paper cufe2o4, nanocrystalline powders were prepared. also, the supported cu ferrite was obtained by impregnation of the supports with cu and fe nitrates solutions, for calcination temperature 450 ºc. the samples were characterized by x-ray powder diffraction (xrd) and fourier transform-infrared spectroscopy (ft-ir). photocatalytic degradation of acid red 206 in water was studied. cufe2...

BACKGROUND AND AIMS Longstanding ulcerative colitis (UC), especially in the presence of epithelial dysplasia, is associated with an increased risk of developing cancer. As dysplasia is not visible during routine endoscopy, at least 40-50 random biopsies in four quadrants every 10 cm are recommended. Fluorescence endoscopy after sensitisation with 5-aminolaevulinic acid (5-ALA) was assessed for ...

The use of Azolla filiculoides (AF) for the removal of Acid Red 88 dye (AR88) from aqueous solutions at different contact times, temperatures, pH, adsorbent doses and initial dye concentration was investigated. The extent of dye removal decreased with increasing adsorbent dosage and AR88 concentration, also increased with increasing contact time and temperature. The adsorption isotherms are des...

Background—Red blood cell transfusion can both benefit and harm. To inform decisions about transfusion, we aimed to quantify associations of transfusion with clinical outcomes and cost in patients having cardiac surgery. Methods and Results—Clinical, hematology, and blood transfusion databases were linked with the UK population register. Additional hematocrit information was obtained from inten...

The purpose of this study was to evaluate the effects of processing, i.e. heating (98 !C, 10 min), freezing (!20 !C) and freeze-drying on anthocyanins, carotenoids, and vitamin C in summer fruits and vegetables, i.e. cherries, nectarines, apricots, peaches, plums, carrots and red bell peppers. The commodities were collected from growers located in the Otago region (namely Cromwell, Roxburgh, Mo...
