Burcu Ileri 대한환경공학회 2022 Environmental Engineering Research Vol.27 No.1
In this study, the removal of acid violet 7 (AV7) and basic violet 10 (BV10) synthetic dyes was investigated using fly ash alone, ultrasound (40 kHz) alone, and combined ultrasound/fly ash with various experimental parameters such as fly ash dose, contact time, and initial concentration of dye. The adsorption capacity of the ultrasound/fly ash process increased from 5.10 to 7.43 mg g<SUP>-1</SUP> for AV7, and increased from 5.16 to 7.51 mg g<SUP>-1</SUP> for BV10 compared with using fly ash alone. The sono-assisted adsorption process was successful in improving the dye uptake capacity with cavitation bubbles and acoustic waves, and thus AV7 and BV10 were removed with a shorter contact time and lower fly ash dose. Obtained regeneration and reuse experiment results showed that the fly ash could be reused for four consecutive cycles of the sono-assisted adsorption process, while fly ash could be reused for two consecutive cycles of the adsorption process. The adsorption kinetics for AV7 and BV10 onto fly ash fitted Lagergren’s first-order adsorption kinetic model well. The Langmuir isotherm best described the adsorption with fly ash alone and ultrasound/fly ash process for AV7 and BV10.

Present study was aimed at selection of psychrotrophic Leuconostoc spp., having dextransucrase activity from native fruits and sauerkraut. Fifty-six colonies of lactic acid bacteria producing dextransucrase were isolated and characterized by physiological-biochemical methods. Seven isolates with high dextransucrase activities (0.68-1.63 IU/mL) were studied in detail including characterization by 16S rDNA sequence comparison. It was found that these isolates grow faster and produced dextransucrase earlier than Leuconostoc mesenteroides B512FMC-13Glc, a mutant form of the commercial strain. Molecular weights of the dextransucrases produced by 7isolates were determined and acceptor reactions using maltose were studied. Dextranase hydrolysis products of dextrans produced by new enzymes were similar to those of commercially produced B-512 F dextran. The new dextransucrases could find industrial uses and the strains isolated (AN 39-1, Or2p-2, Mu3, and Mu10) could be used as prebiotic producing starters in food fermentations due to having high dextransucrase activity and their growth at 4℃.

Objective: To evaluate the long-term effects of self-ligating brackets (SLBs) on transverse dimensions of arches and skeletal and soft tissues and to quantitatively evaluate the treatment outcome after non-extraction treatment with SLBs. Methods: The sample consisted of 24 (18 female and six male) subjects, with a mean age of 14.23 ± 2.19 years, who received treatment with the Damon<SUP>®</SUP>3 appliances. Complete records including cephalometric radiographs and plaster models were obtained before treatment (T1), immediately after treatment (T2), six months after treatment (T3), and two years (T4) after treatment. Digital study models were generated. Twenty lateral cephalometric, six frontal cephalometric, and eight dental cast measurements were examined. The Peer Assessment Rating index was used to measure the treatment outcome. The Wilcoxon test was applied for statistical analysis of the changes. Results: There were significant increases in all transverse dental cast measurements with active treatment. There was some significant relapse in the long term, particularly in maxillary width (p < 0.05). Statistically significant increases were found in nasal (p < 0.001), maxillary base, upper molar, lower intercanine, and antigonial (p < 0.05) widths in T1-T2. Lower incisors were proclined and protruded in T1-T2. Conclusions: SLBs correct crowding by mechanisms involving incisor proclination and protrusion and expansion of the dental arches, without induction of clinically significant changes in hard and soft tissues of the face.

Objective: The aim of this study is to investigate the influence of pregnancy on prognosis of thyroid cancer. Methods: A total of 72 patients aged between 15-45 years who underwent total or subtotal thyroidectomy and subsequently radioablation were followed up under suppression. Individuals who had term pregnancies after diagnosis of cancer (group 1, n: 36) and who were non-pregnant (group 2, n:36) were included in the study. Both groups were compared in terms of scintigraphic relapse and metastasis, ultrasonographic relapse, stage change of lympadenopathy at the beginning and at the end of the study. Results: Relapse was detected in 4 out of 36 pregnant patients (11.1%) and in 5 out of 36 non-pregnant patients (13.9%) with no significant difference between groups (p=1.00). Pathologic lymphadenopathy was detected in 2 out of 36 pregnant patients (5.6%) and in 2 out of 36 non-pregnant patients (5.6%) (p=1.00), and metastasis in 3 (8.3%) and in 1 (2.8%), respectively (p=0.61). While stage change was detected in only one pregnant patient (2.8%), and none of the non-pregnant again there was no significant difference (p=1.00). Conclusions: We conclude that pregnancy does not have an influence on prognosis of thyroid cancer.
