Heavy metals bioconcentration and translocation in plants: The influence of a thermal power site

*Gök, Gülden ( Aksaray, Yazar ) *Bilgin, Melayib ( Aksaray, Yazar )Soil and plant samples were collected from agricultural areas under the influence of thermal power plant and ash samples were collected from ash storage area. In samples, As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, V, Zn, Al, Ca, Fe, K, Na and S were analyzed using ICP-MS. The aim of the study is to determine the set of elements mainly emitted from the components of the thermal power plant, as well as the major sources influencing the plant elemental levels. In the ash samples, significant enrichments of S, Mo, As, Ca, Cd and Cr were determined. Sugar beet leaves were considered to be a potential Na hyperaccumulator due to the translocation factor (TF) of 13525 calculated in its leaves. As a result of the Principal Component Analysis applied to the bioconcentration factors (BCFs) determined in plant parts, the main source of Co, Pb, Ni, Cr, Fe, Al, V, As, Mn and Cd was determined as geochemical background level of soil. Cu, Zn, and Mo enrichment in plant parts were found linked with agrochemicals used on the site, while another source of Cd was detected as phosphate fertilizers. Mo and S are identified as the main elements sourced from thermal power plant units...

A study on the development of the learning styles scale for 5-6 year-old children

Bu çalışmanın amacı 5-6 yaş çocukları için öğrenme stillerini değerlendiren geçerli ve güvenilir bir ölçme aracı geliştirmektir. Araştırmanın örneklemini ondört farklı okulun anasınıfına devam eden olan 5-6 yaş grubu 270 çocuk oluşturmuştur. Yapılan istatistiksel analizler sonucunda ölçeğin 27 maddeli, üç faktörlü bir yapıdan oluştuğu ve üç faktörün birlikte açıkladıkları varyans oranının %64 olduğu görülmüştür. “5-6 Yaş Çocukları İçin Öğrenme Stilleri Ölçeği”nin Cronbach Alfa iç tutarlılık katsayıları ölçeğin bütünü için .95 olarak hesaplanmıştır. Ölçeğin test-tekrar test güvenirliği korelasyon katsayısının .85 olduğu görülmüştür. Ölçekteki maddelerin üst %27 ile alt %27’lik grupların madde ortalama puanları arasındaki farklar için uygulanan t testi sonuçlarına göre, tüm farkların üst %27 grup lehine anlamlı olduğu saptanmıştır. Elde edilen bu bulgular ışığında “5-6 Yaş Çocukları İçin Öğrenme Stilleri Ölçeği”nin geçerli ve güvenilir bir ölçme aracı olduğu söylenebilir

Vokal kord paralizi ile seyreden troid tüberkülozu

Tuberculosis of the thyroid gland, a rare condition, was present in the case of a 45 year-old woman presenting her complaints as hoarseness and fever. We performed an operation and administered an antituberculosis treatment afterwards, observing a case of tuberculuous abscess of the thyroid gland as a primary sited location copying thyroid malignancy with left vocal cord paralysis.Tiroid bezinde tüberküloz nadir bulunur. Ses kı- sıklığı ve ateş yakınması olan 45 yaşındaki kadın hasta opere edildikten sonra, antitüberküloz tedavi verildi. Olgumuzun, sol vokal kord paralizisi olup, tiroid kanserini taklit eden, tiroid bezinde pimer yerleşimli tüberküloz absesi olduğu saptandı

Lung Abscess in Crimean-Congo Hemorrhagic Fever: A Case Report

Crimean-Congo hemorrhagic fever is a viral zoonotic infection that affects multiple organs and systems, and causes various complications and death. Here, we present a case of a Crimean-Congo hemmorrhagic fever with pulmonary abscess complication, which has not been previously reported

The Effect of Smoking Dependence Level on Patients 'Anxiety Levels of COPD Patients

Aim: COPD is a significant public health problem that also affects the mental aspect. In this study we aimed to show the effects of smoking on anxiety in COPD patients by measuring anxiety levels. Materials and Methods: Our study was conducted in outpatient clinics of Family Medicine Department and Chest Diseases Department at Ankara Training and Research Hospital between March-June 2016. 147 individuals with COPD were included in the study. Demographic questions, ‘‘State- Trait Anxiety Inventory’’ and pulmonary function test were applied to all patients while ‘‘Fagerstrom Test for Nicotine Dependence’’ was only for the current smokers. The data were analyzed using SPSS statistical software version 16.0. Results: 147 COPD patients in the age range of 35-80 years including 56 females (%38,1) and 91 males (%61,9) were enrolled in the study. State- Trait Anxiety Inventory was applied to all patients. Current smokers with a number of 86 (%58,5) also performed Fagerstrom Test for Nicotine Dependence. The average anxiety scores of COPD patients were higher than the normal values. COPD severity, presence of comorbid chronic illness and age were significantly correlated with anxiety levels of the patients. Increasing severity of COPD, the presence of comorbid chronic illness and higher ages increased the levels of anxiety in COPD patients. Conclusion: Anxiety levels are increased in patients with COPD. Family physicians who see the patients first and most frequent should also evaluate the COPD patients psychologically and should lead them to a psychiatrist if necessary. Besides all COPD patients should be encouraged to quit smoking independently of anxiety levels

Konjenital glikozilasyon bozukluklarında hücresel oksidatif hasar

BACKGROUND: Congenital disorders of glycosylation (CDG) are genetic diseases caused by defectiveglycosylation of glycoproteins and glycolipids. Oxidative stress is caused by an imbalance between theproduction of reactive oxygen species (ROS) and the ability of a biological system to readily detoxify thereactive intermediates. We aimed to demonstrate the cellular oxidative damage in CDG patients bymeasuring oxidative stress biomarkers.MATERIAL/METHOD: We assessed the serum levels of 19 CDG patients and 14 healthy controls forreactive oxygen species (ROS), malondialdehyde (MDA), total sulfhydryl content (SH), advanced oxidationprotein product (AOPP), advanced glycation end product (AGE) and ferric reducing antioxidant power(FRAP).RESULTS: The median ROS levels were 104.1-106.3 (79.3-147.7) and 126.8-138.2 (69.4-262.2) in controlsand in patients respectively. There was a significant difference between two groups (p, 0.039). Median AGElevels were 170.6 (145.5-356) in controls and 269.8-273.6 (150.1-456.9) in CDGs (p, 0.002). Total SH levelsmedian was 223.4-228.3 (196.4-287.2) in the controls and 272.5-282.3 (206.2-657.9) in patients. Patients`total SH levels were higher than that of the control group (p, 0.17). Mean FRAP values are 318.9∓90.1 incontrols and 386.0∓143.7 in CDGs. In comparison to the control group, FRAP levels of CDGs werenoticeably higher. Median MDA values were 3.3-3.4 (2.4-7.8) in controls and 2.7 (1.3-9.7) in CDGs. MedianAOPP levels of control group were 101.2 (32.3-283) and 96.9-100.2 (34.7-570.5) in patients. A differencebetween the groups MDA and AOPP was not observed.CONCLUSION: Most of the proteins and lipids in the body need to be glycosylated and CDGs arecharacterized by multisystem involvement. In this study, we have demonstrated cellular damage in CDGsand suggest that support of antioxidant drugs to the treatment protocol would be beneficial
