Indoor environmental quality in chemistry and chemical engineering laboratories at Izmir Institute of Technology

AbstractIndoor air pollution in university research laboratories may be important to building occupants, especially for those who work in the laboratories. In this study, indoor air quality (IAQ) and indoor environmental comfort were investigated in research laboratories of two departments at a university. PM2.5, PM10, TVOC (total volatile organic compounds), and CO concentrations, and three comfort variables which are temperature, relative humidity, and CO2 were measured. PM2.5 concentration was determined gravimetrically by collecting particles on glass fiber filters, whereas the remaining pollutants and comfort variables were measured using a monitoring device. IAQ measurements showed that levels of all pollutants were under the limits in both of the departments except for TVOC in one laboratory which had a mean concentration of 182ppb. The comfort variables were in the comfort ranges for laboratories in both of the departments except for temperature in one laboratory with a mean value of 30 °C. In conclusion, measures are needed for extensive uses of organic solvents because ventilation may not be sufficient to keep VOC concentrations within the limits, and to provide thermal comfort

Extramedullary Anaplastic Plasmacytoma of the Bladder: A Case Report and Current Literature Review

Extramedullary plasmacytoma (EMP) can be found in any organ as a primary tumor or as part of multiple myeloma (MM). It mostly affects the head and neck region, upper respiratory tract and gastrointestinal tract. Bladder is one of the organs in which EMP is rarely seen. In this case, we reported a patient with a history of MM developed recurrence in the form of plasmacytomas in the bone and the bladder without bone marrow involvement after bone marrow transplantation. This recurrence has been reported as anaplastic plasmacytoma (AP) which is a rare variant of plasmacytoma. It is important to make a differential diagnosis of this subtype, which is very similar immunohistochemically with plasmablastic lymphoma (PBL) and responds poorly to treatment. This distinction is often made clinically. In this case, the pathological diagnosis of tumor in the urinary bladder was accepted as AP due to the absence of HIV and EBV infections and the presence of MM history. Immunotherapy was started for the patient who responded poorly to chemotherapy, but the recurrence of mass in the bladder was observed. Our case report is important in terms of its rare presentation in the bladder and aggressive character

GENERAL CHARACTERISTICS OF VINEYARD FARMS IN DENIZLI PROVINCE

WOS: 000454318300024Grapes produced in many provinces of Turkey, with the possibility to evaluate in different ways and also as an agricultural product which is also an important contribution to foreign trades. According to the latest data, Turkey ranks in fifth regarding the total vineyard area and sixth in grape production in the world countries. This study aims to reveal the economic analysis of grape production. In this framework, determining the economic structures, annual activity results of vineyards, and calculating the production costs in the case of Denizli province. It was determined that grape production mostly made in aqueous conditions and goble training production was done in non-irrigated vineyards. Because of this situation, according to the wired training vineyards, it was found that the yield was about 1.6 times higher than the goble training system. It was determined that the labour force was used intensively in both production systems. However, more labour was used in the wired training vineyards than in the goble training system. It was determined that the gross production value be higher in the wired training vineyards. According to these results, it can be said that the wired training system was more advantageous regarding economic criteria

TECHNICAL EFFICIENCY IN GRAPE PRODUCTION: A CASE STUDY OF DENIZLI, TURKEY

WOS: 000454318300030In many parts of the world, viticulture has become primary agricultural importance throughout history. The main reason for this is that it is economically productive with an assessment of grapes as fresh wine, dried fruit, fruit juice and other manufactured products. The aim of this was to determine the resource utilisation success of vineyard in Denizli province, which has an important share in Turkeys grape production. The primary material of the study was the data obtained from the grape producers in selected villages in Civril, Cal and Buldan Districts of Denizli Province. The sample size was calculated by using proportional sampling method. Sample volume was found 96 farmers in 95% confidence interval and the 10% margin of error. Data envelopment method (DEA) was used in the research to measure technical efficiency in grape production. Data Envelopment Method is used to evaluate the efficiency of a certain number of production units. The technical efficiency, scale efficiency and pure technical efficiency calculated according to input and the results were calculated and compared to irrigated and non-irrigated vineyards. Interviewed producers were 49 years old, educated seven years, and their agricultural experience was 26 years. According to the findings, respondents were asked how much they could reduce their input on the efficiency limit, and some suggestions were made for inefficient vineyards

Relation of Serum 25 Hydroxy Vitamin D3 Levels with Insulin Resistance in Type 2 Diabetic Patients and Normal Subjects

Hypovitaminosis D is supposed to be associated with diabetes mellitus and metabolic syndrome. Defects in pancreatic β cell function and/or insulin sensitivity are often present, to develop glucose intolerance or type 2 diabetes mellitus. There are accumulating evidence that vitamin D may influence these mechanisms. Aim of our study was to test the hypothesis of an association between hypovitaminosis D and insulin resistance in diabetic patients and normal subjects. We studied 101 type 2 diabetic patients and 60 controls. After detailed physical examination the venous blood was withdrawn, anthropometric measurements were taken, then an indirect measure of insulin resistance was calculated. Study population composed of diabetic and control groups. An indirect insulin resistance index was calculated and compared with other parameters including their 25 hydroxy vitamin D3 levels. In diabetic patients without insulin resistance; fasting blood glucose, fasting insulin and indirect insulin resistance index levels were significantly lower compared to diabetic patients with insulin resistance (p [Med-Science 2012; 1(4.000): 305-14

Relationship between osteocalcin levels and gestational diabetes mellitus

Osteocalcin is an osteoblast-derived protein mainly acting on bone formation. There is growing evidence that osteocalcin has an important role in glucose metabolism. It was not fully elucidated in gestational diabetes mellitus. The aim of our study was to investigate osteocalcin levels in gestational diabetes mellitus and its subgroups. We performed a casecontrol cross sectional study and evaluated all the demographic and anthropometric parameters of 80 pregnant women whose age and body mass indices similar, half of them having normal glucose tolerance (NGT) and the other half having gestational diabetes mellitus (GDM). We compared osteocalcin, calcium metabolism parameters, glucose, lipid levels, insulin resistance parameters, and investigated correlations of all parameters in NGT and GDM. We also analyzed GDM subgroups, which were classified according to age, parity, body mass index (BMI), and vitamin D levels. Osteocalcin levels were increased in patients with GDM and in older, multiparous, with low vitamin D or high body mass index GDM subgroups but these increases were not statistically significant (P>0.05). There was a positive correlation between osteocalcin and C peptide in GDM group and also in GDM subgroups with age≥30, multiparous, vitamin D≥20 ng/ml or BMI≥30 kg/m2 (r=0.424, P=0.006; r=0.460, P=0.011; r=0.408, P=0.017; r=0.520, P=0.013; r=0.603, P=0.002 respectively). We also found a negative correlation between Osteocalcin and HDL-cholesterol in GDM and in multiparous, vitamin D≥20 ng/ml or BMI [Med-Science 2019; 8(4.000): 1011-6

Effects of on bacterial translocation in thioacetamide-induced liver injury in rats

Background and study aim: The aim of the present study was to investigate the effects of Lycium barbarum (LB) on bacterial translocation (BT) frequency in thioacetamide (TAA)-induced liver injury in rats. Materials and methods: Group 1 was the control. In group 2 (TAA), rats received TAA daily for 3 days. In group 3 (TAA+LB), Lycium barbarum was administered orally 25 mg/kg for 21 days prior to the first TAA injection. In group 4 (LB), rats received only Lycium barbarum . Results: In our study, Lycium barbarum treatment did not attenuate liver damage. Lycium barbarum treatment decreased ileal E. coli counts and intestinal damage but it did not alter BT frequency. Conclusions: In conclusion, the effects of Lycium barbarum on BT may be related to ongoing severe liver damage in this model
