[1,2,5]thiadiazolo[3,4-G]quinoxaline Acceptor-Based Donor-Acceptor Polymers: Effect of Strength and Size of Donors on the Band Gap
(Wiley, 2017) Gokce, Gurcan; Karabay, Baris; Cihaner, Atilla; Ozkut, Merve Icli
Electrochromic polymers based on [1,2,5]thiadiazolo[3,4-g]quinoxaline acceptor and thiophene, 3,4-ethylenedioxythiophene and 3,3-didecyl-3,4-proylenedioxythiophene donors, namely poly(6,7-diphenyl-4,9-di(thiophen-2-yl)-[1,2,5]thiadiazolo[3,4-g]quinoxaline) (P1), poly(4-(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-9-(2,3-dihydrothieno[3,4-b][1,4]dioxin-7-yl)-6,7-diphenyl-[1,2,5]thiadiazolo[3,4-g]quinoxaline) (P2), and poly(4-(3,3-didecyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-6-yl)-9-(3,3-didecyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-8-yl)-6,7-diphenyl-[1,2,5]thiadiazolo[3,4-g]quinoxaline) (P3), respectively, were electrochemically and/or chemically synthesized and characterized. Electrochemical and optical properties of the polymers were then investigated. The results, which were obtained electrochemically and optically, indicate that the polymers bearing the same acceptor and different donor units have a band gap range of 0.59-1.24 eV depending on the strength and size of the donor units and band gap determination method. A significant finding in this study was the phenomenon that when the acceptor is physically huge, the general rule that a weak donor would have a high band gap whereas a strong donor would have low band gap can be broken due to the torsional angles/steric hindrances involved with physically large donor molecules.

1,3-Dipolar Cycloaddition Reactions of 1-Methyl Betaine With C70-A Theoretical Study
(Amer Scientific Publishers, 2009) Turker, Lemi; Gumus, Selcuk
In the present study, the molecular orbital properties of 1,3-dipolar cycloaddition products of 1-methyl-3-oxidopyridinium betaine with C-70 have been investigated theoretically at the level of PM3 (RHF) type semi empirical quantum chemical calculations and then single point DFT calculations were performed for the energies. The betaine acts as a 4 pi-component across its 2,6-positions and certain C=C bonds of C-70 act as 2 pi-component in the 1,3-dipolar cycloadditions considered presently. Various cycloadducts are structurally possible because C-70 structure possesses 8 different 2 pi-components, therefore 8 different pairs of reaction termini exist. The results indicate that, the cycloadducts (including regioisomers) formed with [6, 6]-type double bond are more stable and less endothermic than adducts formed with the [5, 6]-type with some exceptions. Some structural, spectral and physicochemical properties of these cycloadducts have also been studied.
12 Years After Roboski: Prolonged Grief and Posttraumatic Effects
(American Psychological Association, 2025) Ayhan, C.H.; Tanhan, F.; Yağan, F.; Avcı Erdal, N.; Öztürk, G.; Bedir, G.; Aslangiri, S.
Objective: The Roboski massacre, which took place on December 28, 2011, is remembered as a major tragedy resulting from a cross-border operation by the Turkish Air Force that led to the loss of 34 civilians, including 19 children. This event not only caused significant physical losses but also left a profound psychological, social, and political impact on those affected. An enhanced comprehension of prolonged grief disorder’s development can assist professionals in identifying bereaved individuals requiring assistance and augment the efficacy of treatments. The aim of this study is to examine the relationship between the grief process and symptoms of posttraumatic stress, perceived discrimination, and political trust within the framework of the theory of prolonged grief in a sample of the bereaved family members who lost their relatives in the Roboski massacre almost 12 years postloss. Method: In total, 88 Kurdish individuals (Mage = 37.13, SD = 16.4; 53.4% males) who had lost their close relatives in the Roboski incident in 2011 participated in this study. The Prolonged Grief Scale, the Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, the Perceived Discrimination Scale, and the Political Trust Scale were used to collect data. Results: The findings of the study revealed that, even approximately 12 years after the Roboski massacre, a significant portion of the participants continue to experience symptoms of prolonged grief and posttraumatic stress reactions. There was a positive correlation between prolonged grief symptoms and posttraumatic stress reactions (r =.71) as well as perceived discrimination (r =.53). It was also found that the subdimensions of posttraumatic stress, namely “reexperiencing” (β =.19, p <.05), “negative cognitive alterations” (β =.39, p <.05), and “perceived collective discrimination” (β =.11, p <.05), were significant predictors of prolonged grief. Conclusions: Our findings revealed that professionals should focus on identifying bereaved people who experience prolonged grief after a traumatic loss. Targeting these symptoms may alleviate the exacerbation of persistent grief reactions several years after a traumatic loss.Our findings suggest that addressing prolonged grief disorder following a massacre requires a multifaceted approach that includes early intervention, tailored therapeutic strategies, and robust social support systems. By integrating these elements, mental health professionals can significantly improve outcomes for those affected by traumatic loss, facilitating a path toward recovery and resilience. © 2025 American Psychological Association
1747'den 1796 Yılına Kadar İran'da Taht Kavgaları
(2022) Yanmaz, Mahmut; Tekin, Rahmi
İran, jeopolitik konumu nedeniyle tarih boyunca Doğu-Batı medeniyetleri arasında bir köprü vazifesi görmüştür. İran'ın verimli topraklara sahip olması ve ticaret yolları üzerinde bulunması stratejik önemini daha da artırmıştır. Bu nedenle kadim İran coğrafyasının üzerinde birçok medeniyet kurulmuştur. Bulunduğu konum bakımından kilit bir yerde yer alan İran'da öteden beri savaşlar, göçler ve yıkımlar hiç eksik olmamıştır. Tarihi kaynaklara göre İran'da kurulan devletlerin ilki Medlerdir. Medlerden sonra İran'da Parslar, Ahamenişler, Partlar, Selefkoslar, Sasaniler, İslam Uygarlığı Yönetimi, İlhanlılar, Selçuklular, Akkoyunlular, Karakoyunlular, Safeviler ve Kaçarlar kurulmuştur. Safevi Devleti'nin yıkılmasıyla birlikte Nadir Şah'ın kısa süren saltanatı haricinde yaklaşık bir asır İran'da yönetim bütünlük ve devamlılığı sağlanamamıştır. Horasan bölgesi dışında Kerim Han Zend XVIII. yüzyılda ülkenin büyük bir kısmına hâkim olmayı başarmıştır. Ancak yine de ülke bütününe egemen olamamıştır. Bu sebeple İran'da yönetim boşluğunun bir asra yakın devam ettiği zaman dilimi 'Fetret Devri' ya da 'Vahşet Devri' olarak nitelendirilmiştir. Kaçar Devleti'nin kurucusu Ağa Muhammed Şah, askeri disiplini ve üstün gayretiyle Zendleri tamamen ortadan kaldırıp Horasan'ı Şahruh Han'dan alınca bu devir kapanmıştır. 'Vahşet Dönemi' olarak adlandırılan bu dönemin başlıca taht kavgaları ve siyasi mücadelelerini konu alan çalışmamız bu alanda bir boşluğu dolduracağı için tez konum bu şekilde belirlenmiştir.
1800 Mhz Radio-Frequency Electromagnetic Radiation Induces Oxidative Stress in Rat Liver, Kidney and Brain Tissues
(Yuzuncu Yil Universitesi Tip Fakultesi, 2018) Berköz, M.; Arslan, B.; Yıldırım, M.; Aras, N.; Yalın, S.; Çömelekoğlu, Ü.
Radio-frequency electromagnetic radiation (RF-EMR) represents one of the environmental factor that influence animal organism to stress. In this study we determined the oxidative stress parameters from rat liver, kidney and brain tissues that were exposed to chronic 1800 MHz RF-EMR. Our study was designed in 3 groups as 9 animals in each group. These are; control, sham and RF-EMR exposed group. The control group was not exposed to any procedure; sham group was housed in the same room under the same conditions with equal time period, except that the generator was turned off. RF-EMR exposed group was subjected to 1800 MHz RF-EMR emitted from the signal generator for 2 h per day for eight weeks. All animals that completed the experimental period were sacrificed and liver, kidney and brain tissues of all rats were isolated for analyzing malondialdehyde (MDA), nitric oxide (NO) and reduced glutathione (GSH) levels and superoxide dismutase (SOD) and catalase activities. Liver, kidney and brain MDA and NO levels were higher and GSH level and SOD and catalase activities were significantly lower in RF-exposed group than control and sham groups (p<0.001). No significant difference was observed in terms of tissue MDA, GSH and NO levels and SOD and catalase activities between control and sham groups in each tissue. The results of our study shows that RF-EMR may act as an environmental stressor and cause oxidative and nitrosative damage in liver, kidney and brain tissues. © 2018, Yuzuncu Yil Universitesi Tip Fakultesi.

A 2,2-Dichloropropionic Acid-Degrading Novel Pseudomonas Fluorescence Strain Fatsa001: Isolation, Identification, and Characterization
(Taylor & Francis inc, 2025) Meral, Ulku Binboga; Edbeib, Mohamed Faraj; Kirkinci, Suleyman Faruk; Aksoy, Hasan Murat; Akman, Ayhan; Wahab, Roswanira Abdul; Kaya, Yilmaz
There are mounting concerns over the high concentrations of non-biogenic, toxic halogenated organic compounds being liberated into the ecosystem. Therefore, this study's isolation of a novel bacterium from a contaminated stream in Fatsa, Ordu, Turkey, adept in degrading 2,2-dichloropropionic (of 2,2-DCP) is a welcome endeavor. The ability of the bacterial isolate to utilize 2,2-DCP as the sole carbon and energy source was discovered when the bacterium was observed to grow well on liquid minimal media containing 20 mM of 2,2-DCP, showing a doubling time of 14.2 h. The following genetic and biochemical characterizations revealed that the 16S rRNA sequence of the fatsa001strain is identical (99%) to Pseudomonas fluorescence, after which the sequence was deposited in the NCBI GenBank as Pseudomonas sp. strain fatsa001 (MN098848). The halogen-degrading ability of the P. fluorescens fatsa001 bacterium was again confirmed by the PCR data, which showed the presence of a conserved group of amino acids from the group I dehalogenase gene. It worth mentioning here that this is the first report on a P. fluorescence bacterial strain with the ability to degrade toxic 2,2-DCP. The detoxification ability of this bacterium envisages its practicality as an in situ environmental bioremediation agent.
2,6-Bis((e) and Its Metal(Ii) Complexes: Synthesis, Spectroscopy, Biological Activity, and Photoluminescence Features
(Wiley-v C H verlag Gmbh, 2013) Gulcan, Mehmet; Zengin, Huseyin; Celebi, Metin; Sonmez, Mehmet; Berber, Ismet
The preparation, characterization, magnetic measurements, antimicrobial activity, and photoluminescence properties of a number of metal complexes with a Schiff base ligand derived from 2, 6-diformyl-4-methylphenol and 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-thione are reported herein. UV/Vis spectra and magnetic measurements infer square planar stereochemistry for Pd-II and Pt-II complexes, and octahedral arrangement for the other metal complexes. The compounds results in intense emission (where (max) = 402 nm) upon irradiation by UV light. The photoluminescence quantum yields and long excited-state lifetimes of the ligand and its complexes were calculated as 42% and 3.94 ns, respectively. The photoluminescence intensities and quantum yields of metal complexes changed upon complexation with various metal ions. The ligand and its complexes are of interest as organic emitting materials for electroluminescent devices. The complexes were additionally evaluated for in vitro the antimicrobial activity against bacterial and fungal strains. While Cu-II, Co-II, and Pt-II complexes have good antifungal efficiency against yeast (MICs, 80 gmL(-1)), only the complex [Cu(L)(AcO)]4H(2)O had effective and selective antimicrobial activity against all tested microorganisms with MIC values in the range of 40-80 gmL(-1), except for E. coli ATCC 4230. This study suggests that the complex [Cu(L)(AcO)]4H(2)O may be a new potential antimicrobial substance towards bacteria and fungi.

2-Phenyl Substituted Benzimidazole Derivatives: Design, Synthesis, and Evaluation of Their Antiproliferative and Antimicrobial Activities
(Springer Birkhauser, 2022) Ersan, Ronak Haj; Kuzu, Burak; Yetkin, Derya; Alagoz, Mehmet Abdullah; Dogen, Aylin; Burmaoglu, Serdar; Algul, Oztekin
The inability to meet the desired outcomes of anticancer treatment and decrease in treatment success of bacterial and fungal infections accelerated research in these areas. Our research group has conducted numerous studies, especially on benzimidazole ring systems' antiproliferative and antimicrobial activities. In this study, the antiproliferative activity of benzimidazole compounds was tested against A549, A498, HeLa, A375, and HepG2 cancer cell lines by MTT assay. All compounds exhibited good to potent antiproliferative activity against all tested cancer cell lines. Compounds 6-chloro-2-(4-fluorobenzyl)-1H-benzo[d] imidazole (30) and 6-chloro-2-phenethyl-1H-benzo[d]imidazole (46) were especially active against HeLa and A375 cancer cell lines with IC50 values in the range of 0.02-0.04 mu M. In contrast, compounds 6-chloro-2-((p-tolyloxy)methyl)-1H-benzo[d] imidazole (67) and 5(6)-chloro-2-((4-hydroxyphenoxy)methyl)-1H-benzimidazole (68) were active against A549 and A498 cancer cell lines with an IC50 value of 0.08 mu M. These compounds (30, 46, 67, and 68) were less toxic to normal human cells than the positive control compound methotrexate, which was screened to determine its toxicity against normal cell lines (HEK293). In the second part of the study, all compounds were tested to demonstrate their antimicrobial properties. All compounds exhibited moderate activity against all tested bacteria and fungi. However, some phenoxy methyl derivatives 5-chloro-2-((4-chlorophenoxy)methyl)-1H-benzo[d]imidazole (69) and 5,6-dichloro-2-((4-chlorophenoxy)methyl)-1H-benzo[d] imidazole and (74) were most active against Candida (<3.90 mu g/mL). Molecular docking studies were carried out against certain proteins in order to identify potential targets of the antiproliferative effects of the synthesized compounds. The docking scores of the compounds were found to be significantly compatible with the antiproliferative activity results. [GRAPHICS] .

The 23 October 2011 Mw7.0 Van (Eastern Turkey) Earthquake: Interpretations of Recorded Strong Ground Motions and Post-Earthquake Conditions of Nearby Structures
(Earthquake Engineering Research Institute, 2014) Akansel, V.; Ameri, G.; Askan, A.; Caner, A.; Erdil, B.; Kale, O.; Okuyucu, D.
A major thrust-fault earthquake of MW = 7.0 occurred on 23 October 2011 at 10:41:21 UTC in the eastern Anatolian region of Turkey, severely affecting the nearby towns of Van and Erciş. In this study, a few strong-motion records from the epicentral area are analyzed in order to investigate the characteristics of the ground motions. Also reported are the post-earthquake field observations for various types of structures, such as buildings, bridges, historical structures, tunnels, and dams within the vicinity of the fault plane. The spatial distribution of damage indicates a noticeable hanging-wall effect. The special-type structures are observed to experience far less damage, as opposed to the building structures in the region pointing to the need for strict compliance to seismic building code and the corresponding construction requirements.© 2014, Earthquake Engineering Research Institute.

(Springer, 2013) Zorer, O. Selcuk; Sahan, T.; Ceylan, H.; Dogru, M.; Sahin, S.
The concentrations and distributions of natural radioactivity, uranium and radon in lake waters from around Van, Turkey were investigated with an aim of evaluating the environmental radioactivity. Fourteen lake waters were collected from different six lakes around Van (Turkey) to determine U-238, Rn-222 and total alpha and total beta distributions in 2009. The total alpha and total beta activities were counted by using alpha/beta counter of the multi-detector low background system (PIC-MPC-9604) and the U-238 concentrations were determined by inductively coupled plasma-mass spectrometry (Thermo Scientific Element 2) and radon concentrations were measured with the solid state nuclear track detector technique. The activity concentrations ranging from ND to 0.039 Bq L-1 and from 0.026 to 3.728 Bq L-1 for total alpha and beta, respectively, and uranium concentrations ranging from 0.083 to 3.078 mu g L-1, and radon concentrations varying between 47.80 and 354.86 Bq m(-3) were observed in the lake waters.

(Taylor and Francis Ltd., 2014) Selçuk Zorer, Ö.; Daǧ, B.
As part of the national survey to evaluate natural radioactivity in the environment, concentration levels of total radioactivity and natural uranium have been analysed in drinking water samples. A survey to study natural radioactivity in drinking waters was carried out in the Van province, East Turkey. Twenty-three samples of drinking water were collected in the Van province and analysed for total α, total β and 238U activity. The total α and total β activities were counted by using the α/β counter of the multi-detector low background system (PIC MPC-9604), and the 238U concentrations were determined by inductively coupled plasma-mass spectrometry (Thermo Scientific Element 2). The samples were categorised according to origin: tap, spring or mineral supply. The activity concentrations for total α were found to range from 0.002 to 0.030 Bq L-1 and for total β from 0.023 to 1.351 Bq L-1. Uranium concentrations ranging from 0.562 to 14.710 μg L-1 were observed in drinking waters. Following the World Health Organisation rules, all investigated waters can be used as drinking water. © 2013 © 2013 Taylor & Francis.

3-Acrylamidopropyl Cationic Hydrogel Modified Graphite Electrode and Its Superior Sensitivity To Hydrogen Peroxide
(Taylor & Francis inc, 2019) Caglar, Aykut; Kazici, Hilal Celik; Alpaslan, Duygu; Yilmaz, Yonca; Kivrak, Hilal; Aktas, Nahit
A highly sensitive hydrogen peroxide (H2O2) sensor is fabricated by the synthesized 3-Acrylamidopropyl-trimethylammoniumchloride (p(APTMACl)) hydrogel to covered of pen- graphite (PG) electrodes. (p(APTMACl))-PG electrode is characterized using scanning electron microscopy (SEM), Fourier Transform Infrared (FTIR) spectroscopy, and thermogravimetric analysis (TGA). The electrochemical properties of these sensors are investigated by cyclic voltammetry (CV), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS). The CV behavior of (p(APTMACl))-PG electrode is investigated in 0.1M PBS (pH 7, 5mm diameter of mold). The developed sensor displays significantly enhanced electrocatalytic activity through the H2O2 detection. Linear response of the sensor to H2O2 were observed in the concentration range from 0 to 130 mu M (R-2 = 0.99) with a detection limit of 1.08x10(-6) M, quantification limit of 3.62x10(-6) M (S/N=3) and sensitivity of 2375 mu A/mMcm(2). In addition, interference studies reveal that (p(APTMACl))-PG electrode is not affected by ascorbic acid (AA), uric acid (UA), and dopamine which are common interfering species. The developed sensor is also successfully applied to detect H2O2 in real commercial samples. This study describes a novel strategy to sensing characteristics to hydrogen peroxide by p(APTMACl)-PG electrode.
A 3-Cm Single-Port Video-Assisted Thoracoscopic Lobectomy for Lung Cancer
(Lippincott Williams & Wilkins, 2015) Ocakcioglu, Ilhan; Sayir, Fuat; Dinc, Mustafa
Video-assisted thoracoscopic surgery is advantageous over traditional surgical practices, because of a faster postoperative recovery period, less pain, and a shorter hospital length of stay. There is no single standard technique in the video-assisted thoracoscopic surgery approach. Although these minimally invasive resections are habitually performed through 3-port or 4-port incision, we performed a left lower lobectomy in a 54-year-old male patient for lung cancer, through a 3-cm single-port incision.
