Varieties of belonging among migrants: Turkish migrants in Norway
This article examines different ways of belonging among migrants of Turkish origin who were born in Türkiye and are currently living in Norway (in/around Oslo and Drammen). The discussion in the article is based on the findings of semi-structured interviews conducted between March 2019 and August 2020 with 71 Turkish migrants as part of a qualitative study. Different categories of responses to the questions about belonging and the meanings respondents attached to belonging/not belonging are discussed. The paper aims to demonstrate the heterogeneity and complexity of feelings of belonging among the members of an ethnic group that is assumed to feel belonging to their country of origin rather than the destination country in the context of Europe. Additionally, the paper also aims to elaborate on what migrants actually mean when they talk about their belonging (or not belonging) to territories such as the country of origin or destination country, and collectivities like nations. Here it is argued that questioning and criticizing migrants’ feelings of belonging (especially to their countries of origin) as a part of civic integration agendas is an effort to intervene in and have control over their emotions. This claim to the right to intervene in migrants’ emotional lives is approached critically.publishedVersio
Complex cytogenetic findings in the bone marrow of a chronic idiopathic myelofibrosis patient
Chronic idiopathic myelofibrosis is a myeloproliferative disorder characterized by splenomegaly, myeloid metaplasia and reactive bone marrow fibrosis. Karyotype analysis of the bone marrow is an integral part of the diagnosis, especially as a discriminative tool in ruling out reactive conditions. The frequency of clonal cytogenetic anomalies in this disease is the highest among its group, varying between 30 and 75%. Among these, trisomy 1q, 20q-, 13q- and +8 are the most common aberrations. Here we report a 66-year-old male patient whose bone marrow biopsy revealed signs of chronic myeloproliferative changes and dysmegakaryopoiesis. He was administered hydroxyurea treatment, splenic radiotherapy and multiple transfusions. The patient worsened in the following months and the second bone marrow biopsy revealed myelofibrosis. Cytogenetic analysis of this bone marrow sample revealed a complex karyotype reported to be 46,XY,del(9) (q22q34),t(8;17;21)(q22;q21;q22)[23]/46,XY[2], with a previously undefined three-way translocation and deletion in chromosome 9. The patient died shortly thereafter
Investigation of The Effect of N-Nitrozo-N-Ethylure On Zebrafish (Danio rerio) Testicular Histology
N-Nitrozo bileşikleri, 20. yüzyılın başından itibaren bilinen, ancak 1950’lerden sonra canlı sağlığı üzerine etkileri daha çok dikkat çeken bileşiklerdir. N-Nitrozo-N-Etilüre (ENU) günümüzde gıda ürünlerini koruyarak raf ömrünü uzatmada kullanılan N-Nitrozo çeşitlerindendir. Deney hayvanları üzerinde yapılan araştırmalar sonucunda toksik, teratojenik, mutajenik ve kanserojenik etkilerinin olduğu ortaya konmuştur. Bu çalışmada ENU maddesi uygulanan, erkek zebra balıklarının testis dokusunda meydana gelen değişimler histopatolojik olarak araştırılmıştır. Çalışma için bir kontrol ve dört deney grubu olmak üzere toplam beş grup oluşturulmuştur. Deney grubundaki akvaryumlara, 0,25 mM, 0,50 mM konsantrasyonlarda birer ve ikişer saatlik ENU uygulanmış olup 6. gün sonunda diseksiyon yapılmıştır. Alınan zebra balığı testis dokusuna rutin histolojik işlemler uygulanmıştır. Konsantrasyon ve uygulama süresinin artışına bağlı olarak deney gruplarının testis dokusunda, seminifer tübüllerde yapısal bozulmalar, vakuolizasyon, spermatogenik seriye ait hücre kümelerinde konsantrasyona bağlı olarak azalma, bazı hücrelerde hipertrofi ve bağ dokusunda dejenerasyonlar tespit edilmiştir. Histolojik incelemeler neticesinde ENU’ya maruz kalan erkek zebra balıklarının testis dokularında olumsuz değişimler belirlenmiştir.N-Nitrozo compounds are known from the beginning of the 20th century, but after 1950s their effects on living health were more prominent. N-Nitrozo-N-Ethylurea (ENU) is one of the N-Nitrozo varieties used today to protect food products and extend shelf life. As a result of research on experimental animals, toxic, teratogenic, mutagenic and carcinogenic effects have been revealed. In this study, changes in testicular tissue of male zebrafish treated with ENU were investigated histopathologically. A total of five groups, one control and four experimental groups, were formed for the study. ENU was applied to the aquaria in the experimental groups at concentrations of 0.25 mM and 0.50 mM. Routine histological procedures were applied to the zebrafish testis tissue. Due to the increase in concentration and application time, structural disruptions in seminiferous tubules, vacuolization, decrease in cell clusters, hypertrophy in some cells, degenerations in connective tissue were detected in testicular tissue of the experimental groups. Histological examinations revealed negative changes in testicular tissues of male zebrafish exposed to ENU
Does electrocardiography at admission predict outcome in Crimean-Congo hemorrhagic fever
Background & objectives: Crimean-Congo hemorrhagic fever is an acute viral hemorrhagic fever withconsiderable mortality. Despite increasing knowledge about hemorrhagic fever viruses, the pathogenesis ofCrimean-Congo hemorrhagic fever and causes of death were not well described. We aimed to evaluate whetherthere were electrocardiographic parameters designating mortality among these patients.Study design: This retrospective study was performed among confirmed Crimean-Congo hemorrhagic fevercases in Turkey. Electrocardiography was available in 49 patients within 24 h of hospitalization. Allelectrocardiograms were evaluated by two expert cardiologists according to Minnesota coding system.Results: Among patients with available electrocardiograms, there were 31 patients who survived, and 18patients who died of Crimean-Congo hemorrhagic fever. Both groups were similar in terms of age, sex, bodytemperature, heart rate, and blood parameters. T-wave changes and bundle branch block were more frequentlyencountered among those who died. Presence of T-wave negativity or bundle branch block in this cohort ofpatients with Crimean-Congo hemorrhagic fever predicted death with a sensitivity of 72.7%, specificity of92.6%, positive predictive value of 88.9%, negative predictive value of 80.6%.Conclusions: We think within the light of our findings that simple electrocardiography at admission may helprisk stratification among Crimean-Congo hemorrhagic fever cases
Recent Progress in Extending the Cycle-Life of Secondary Zn-Air Batteries
Secondary Zn-air batteries with stable voltage and long cycle-life are of immediate interest to meet global energy storage needs at various scales. Although primary Zn-air batteries have been widely used since the early 1930s, large-scale development of electrically rechargeable variants has not been fully realized due to their short cycle-life. In this work, we review some of the most recent and effective strategies to extend the cycle-life of Zn-air batteries. Firstly, diverse degradation routes in Zn-air batteries will be discussed, linking commonly observed failure modes with the possible mechanisms and root causes. Next, we evaluate the most recent and effective strategies aimed at tackling individual or multiple of these degradation routes. Both aspects of cell architecture design and materials engineering of the electrodes and the electrolytes will be thoroughly covered. Finally, we offer our perspective on how the cycle-life of Zn-air batteries can be extended with concerted and tailored research directions to pave the way for their use as the most promising secondary battery system of the future
The Role of Oxygen Free Radicals in Acute Renal Failure Complicating Obstructive Jaundice: An Experimental Study
Oxydant injury is considered to be an important mechanism in the pathophysiology of acute renal failure. It has been thought that decrease in extracellular and intracellular fluid and endotoxemia seen in obstructive jaundice may cause an increase in production of oxygen free radicals and impairment in antioxydant defense mechanism. This study is designed to investigate the possible role of oxydant injury in renal failure seen in jaundiced patients. In this study, 28 rats were divided into four groups: Control(C) (N=7); Renal ischemia (RI) (N=7); Obstructive jaundice+renal ischemia (OJ+RI) (N=7); Obstructive jaundice (OJ) (N=7). All groups were compared with each other according to renal failure findings and enzyme activities, such as Xanthine oxidase (XOD), Superoxide Dismutase (SOD) and Catalase in renal cortex and Glutathione Peroxidase (GSH-Px), in blood at 3rd day after ischemia and reperfusion. Renal failure findings monitored by blood urea and creatinine levels, seemed more evident in OJ+RI than RI group (p <0.05). When compared with RI, in OJ+RI group, increase in XOD activity at 3rd day was statistically significant [0.259 ±0.01 U/g (tissue) and 0.362±0.03 U/g (tissue) respectively] (p <0.05). SOD and GSH-Px activities of each ischemic group at 3rd day were decreased compared to non-ischemic groups. This fall was significant (p <0.05). But there was no statistical difference between jaundiced and non-jaundiced groups. Alterations in catalase activities also had no statistical significance

Citogenetičko oštećenje u turskih radnika na koksnim pećima izloženih policikličkim aromatskim ugljikovodicima: povezanost s genskim polimorfizmima CYP1A1, CYP1B1, EPHX1, GSTM1, GSTT1 i GSTP1
The aim of this study was to determine the frequencies of chromosomal aberrations (CA) and cytochalasinblocked micronuclei (CBMN) in peripheral blood lymphocytes from Turkish coke oven workers and the influence of CYP1A1, CYP1B1, EPHX1, GSTM1, GSTT1, and GSTP1 gene polymorphisms on these biomarkers. Cytogenetic analysis showed that occupational exposure significantly increased the CA and CBMN frequencies. Gene polymorphisms, on the other hand, did not affect CA or CBMN in either exposed or control subjects. However, due to the limited sample size, our findings need to be verified in future studies with a larger sample.Cilj je ovog ispitivanja bio utvrditi učestalost kromosomskih aberacija (CA) i mikronukleusa (CBMN) u limfocitima periferne krvi turskih radnika na koksnim pećima te utjecaj genskih polimorfizama CYP1A1, CYP1B1, EPHX1, GSTM1, GSTT1 i GSTP1 na te biopokazatelje. Profesionalna je izloženost ovih radnika značajno povećala učestalost CA i CBMN, ali genski polimorfizmi nisu utjecali na ove parametre bez obzira na to je li se radilo o radnicima ili o kontrolnoj skupini. Međutim, značaj je naših rezultata ograničen zbog malog uzorka te su potrebna daljnja istraživanja s većim uzorkom da ih se potvrdi
