The Investigation of the Effects of Plasma Treatment on the Dyeing Properties of Polyester/Viscose Nonwoven Fabrics

AbstractIn this study, Polyester/Viscose (PET/CV) nonwoven fabrics were treated with oxygen plasma application. The plasma application was carried out for 1and 10minutes at low frequency. After then, the samples were dyed with disperse dyes. Where same samples were dyed with carriers, the others were dyed without carriers. Finally, the effects of plasma treatment on dyeing properties of PET/CV nonwoven fabrics were investigated at 3% darkness. The aim of this study is that the effect of hydrophility caused by the plasma application on dyeability properties of samples was investigated

Teachers' Attitudes Toward the Use of Technology in Social Studies Teaching

Technology integration in education is one of the most popular topics in the last decades. Many countries have invested millions of dollars to equip classrooms with technological devices. As well as developed countries, Turkey has conducted several projects to provide technological devices and educational materials to classrooms. Technology has the potential to increase the quality of learning and teaching process. However, having technological devices in classroom alone will not cause the increase of the quality of education. Thus, the purpose of this study is to examine teachers' attitudes toward the use of technology in social studies teaching. Understanding social studies teachers' attitudes is essential because it is a way to figure out how they integrate technology and define barriers. The authors applied quantitative survey method and used cluster sampling to choose participants. The sample of the study consisted of 155 social studies teachers who are currently teaching at middle schools. The use of technology in social studies teaching attitude scale was used to collect data. The findings revealed that teachers have positive beliefs and attitudes toward the use of technology. Also, the findings showed that teachers who are working at private schools have significantly high attitudes than others who are teaching at public schools. Moreover, teachers who took educational technology and teaching material course and attended in-service training have more positive attitudes than others

Effect of Freeze, Oven and Microwave Pretreated Oven Drying on Color, Browning Index, Phenolic Compounds and Antioxidant Activity of Hawthorn (Crataegus orientalis) Fruit

Flowers, leaves and fruits of hawthorn plant are traditionally used for treating diseases like hypertension and atherosclerosis. The medicinal effects of the plant are generally attributed to its phenolic compounds. However, the fruits are perishable materials because of their high content of water, and generally dried and stored to be used outside its season. The main aim of this research was to investigate the effect of different drying methods on phenolic compounds of the hawthorn fruit. Fruits were collected from the wild growing trees in Turkey. De-seeded fruits were dried in freeze-, oven- (60 oC) and microwave pretreated oven drying (microwave application for 5 min at 360 W before drying at 60 oC) methods and analyzed for antioxidant activity, phenolic compounds, total phenolic content and color parameters. Total phenolic content of fresh hawthorn fruits was found as 13.36 mg g-1 DW. Oven- and microwave pretreated oven drying methods had a reductive effect on total phenolic content and antioxidant activity of fruits when compared to freeze drying method. (-)-Epicatechin (994.10 mg kg-1 DW), rutin (765.30 mg kg-1 DW), and procyanidin B2 (553.80 mg kg-1 DW) were the main phenolics of the fruit. Lowest values of these three compounds were observed in oven-dried fruits. Microwave pretreatment oven drying method resulted in browner product. Although the highest phenolic concentration and antioxidant activity were occurred in freeze-dried sample, microwave pretreatment before oven drying could be applied to reduce the time and cost of drying in terms of phenolic compounds and antioxidant activity

Unusual Presentation of Renal Cell Carcinoma: Gluteal Metastasis

Renal cell carcinoma (RCC) has widespread and unpredictable metastatic potential. The most common sites of metastatic RCC are the lungs, lymph nodes, bones, liver, and brain; however the soft tissue metastasis is rare (2,3). Here we report a 76-year-old male patient who had renal cell carcinoma presented with gluteal metastasis. To our knowledge this is the first renal cell cancer case with gluteal metastasis at the initial diagnosis

Mixed Bacteriological Isolation Percentages from the Uterus of Cows Slaughtered due to Infertility

Background: Intrauterine mixed infections are an important problem in cattle breeding. In this study, we aimed to determine the mixed bacteriological isolation rates from the uterus of cows with clinical metritis and to reveal the relationships between the bacteria that isolated together.Methods: For this purpose, sterile swabs were taken from 490 uterus obtained from cattle slaughtered due to infertility in three slaughterhouses and used them to perform microbiological tests. After evaluating the data, it was determined that the bacterial isolation rate from uterus with clinical metritis was 76.14% (n = 268).Results: The rates for 1, 2, 3, 4, and 5 bacteria isolated from the uterus with clinical metritis were 48.13%, 33.96%, 15.30%, 2.24%, and 0.37%, respectively. The isolation rates for Trueperella pyogenes, Fusobacterium necrophorum, and Escherichia coli alone from the uterus with clinical metritis were 27.08%, 28.00%, and 16.51%, respectively. In uterus with clinical metritis, Staphylococcus aureus (16.67%) was the most commonly isolated bacteria with T. pyogenes, Clostridium spp. (16%) co-isolated with F. necrophorum, and coagulase-negative staphylococci (16.51%) and Bacillus spp. (16.51%) were detected with E. coli.Conclusion: As a result, it was concluded that when evaluating the microbiological results for cows with clinical metritis, mixed infections should be taken into more consideration, and the characteristics of the bacteria that isolate together should be considered during the treatment of mixed infections.Keywords: Cattle; Uterine; Isolation; infertility     

The effects of Stanozolol and high protein diet on Colon Anastomosis

Background: Anastomotic leakage after colonic resection and anastomosis are serious complications with high morbidity and mortality. Collagen synthesis is an essential feature of anastomotic healing. Objective: Our study aimed to investigate individual and combined effects of high protein diet and Stanozolol on the intestinal anastomosis in rats. Methods: Total of 48 Wistar-albino rats were divided into four groups. Group C: Control group; Group P: high protein diet (4mg/day) administered by gavage; Group A: group to which stanozolol was administered intramuscularly (i.m) (2mg/kg/day); Group A+P: group to which both stanozolol (2mg/kg/day) i.m and high protein diet (4mg/day by gavage) was administered. In each group, half of the animals underwent surgery on the 3rd postoperative (PO) day and the other half on the 7th PO day for analysis procedures. Bursting pressures of each anastomotic segment, tissue hydroxyproline levels, and histologic tissue repair process were evaluated. Results: On 7th PO day, group A+P had statistically and significantly higher bursting pressures than the control group. Hydroxyproline levels at the anastomotic segment on both 3rd and 7th PO days were also significantly higher in group A+P. Conclusion: A high protein diet and stanozolol do not significantly impact the anastomotic healing when used separately. We concluded that high protein diet and Stanozolol can be used after colorectal surgery in humans but requires further research

Necrotizing Liver Granuloma/Abscess and Constrictive Aspergillosis Pericarditis with Central Nervous System Involvement: Different Remarkable Phenotypes in Different Chronic Granulomatous Disease Genotypes

Chronic granulomatous disease (CGD) is a primary immune deficiency causing predisposition to infections with specific microorganisms, Aspergillus species and Staphylococcus aureus being the most common ones. A 16-year-old boy with a mutation in CYBB gene coding gp91phox protein (X-linked disease) developed a liver abscess due to Staphylococcus aureus. In addition to medical therapy, surgical treatment was necessary for the management of the disease. A 30-month-old girl with an autosomal recessive form of chronic granulomatous disease (CYBA gene mutation affecting p22phox protein) had invasive aspergillosis causing pericarditis, pulmonary abscess, and central nervous system involvement. The devastating course of disease regardless of the mutation emphasizes the importance of early diagnosis and intervention of hematopoietic stem cell transplantation as soon as possible in children with CGD
