Analysis of Probiotic Bacteria Genomes: Comparison of CRISPR/Cas Systems and Spacer Acquisition Diversity
(2021) Ilikkan, Ozge Kahraman; 0000-0001-5843-6868; 35068602; Q-9641-2019
Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) genes constitute an adaptive (acquired) defense system of bacteria and archaea. Here 72 probiotic bacteria genomes were investigated in terms of the presence of CRISPR/Cas systems and phage/plasmid invaders through spacer analysis. 49 CRISPR/Cas systems were detected within probiotic strains, namely,17 type II-A, 10 type I-C, 8 type I-E, 5 Type I-U (I-G), 4 type III-A, 2 type I-B, 1 type I-A, 1 type IV-B, and 1 type II-C. The predicted target of spacers was determined in 25 strains and consequently, three different spacer and target patterns were revealed. The diversity of CRISPR spacers provides insight and understanding to determine strain-specific invaders of probiotic bacteria as well as their relationships between strains. CRISPR systems were clarified in many studies for genomic characterization. However, recently, endogenous genome editing with CRISPR has provided an approach for various genome editing projects. Thus, in the future, producing strain-specific phage-resistant starter cultures or probiotics by endogenous genome editing methods according to phage/plasmid survey can be utilized for industrial and pharmaceutical applications. Therefore, this study intended a comprehensive investigation of CRISPR systems of probiotic bacteria.
THE APPROACH OF ATATURK TO RELATIONS BETWEEN TURKEY AND ALBANIA BEFORE THE PROCLAMATION OF MONARCHY, IN THE LIGHT OF THE DIARIES OF RAUF FICO, THE MINISTER PLENIPOTENTIARY OF ANKARA
(2018) Ozca, Halil
The diaries of RaufFico, Albanian Minister Plenipotentiary to Ankara, gives a lot of useful information about Albania-Turkey relations that had not been stumbled across in the literature until today. The aim of this study is to point out Atatiirk's views on relations between Albania and Turkey, Albania and Italy, as well as his suggestions to Albanian envoy in Ankara about how to overcome the Albanian dependency on Italy. The research is based on the diaries of Fico, Albanian Minister Plenipotentiary to Ankara. The study is limited with focusing on the Italian factor in Albania's relations with Turkey rather than examining all aspects of the relationship between the two independent countries. Fico had had formal education in the Ottoman Empire and occupied bureaucratic posts such as being provincial governor and following independence of Albania started to work for Albanian government as an important diplomat. Therefore, his diaries provide us a plenty of information on the question of Albania's relations with Turkey as well as with Italy, particularly between 1925 and 1928 during which there had been a Republican regime in Albania. In fact, Fico's diaries give perfect information about close relations between Turkey and Albania and the importance given by Mustafa Kemal Atatiirk on these relations at bilateral level, at least until the destruction of the Republican regime by Ahmet Zogu who would proclaim himself as the King of Albania in 1928. The content of the Fico's diaries are very rich in a way that they consist problems of Orthodox Albanians in Istanbul, positions of Albanians in Kosovo, the exchange of Albanian Chams, reforms in Turkey, assassination attempt to Atatirk in izmir and main themes in Nutuk. It should be kept in mind that the scope of this study is confined, first, to suggestions of Ataturk to the Albanian government regarding getting rid of dependency on Italy, and second, to his foresight about Italy's position towards Albania and Turkey. In this respect, the Fico's diaries give invaluable information on all these subjects elaborated in this paper.
Calibration transfer in temperature modulated gas sensor arrays
(2016) Fernandez, L.; Güney, S.; Gutierrez-Galvez, A.; Marco, S.
Shifts in working temperature are an important issue that prevents the successful transfer of calibration models from one chemical instrument to another. This effect is of special relevance when working with gas sensor arrays modulated in temperature. In this paper, we study the use of multivariate techniques to transfer the calibration model from a temperature modulated gas sensor array to another when a global change of temperature occurs. To do so, we built 12 identical master sensor arrays composed of three different types of commercial Figaro sensors and acquired a dataset of sensor responses to three pure substances (ethanol, acetone and butanone) dosed at 7 concentrations. The master arrays are then shifted in temperature (from -50 to 50 degrees C, Delta T = 10 degrees C) and considered as slave arrays. Data correction is performed for an increasing number of transfer samples with 4 different calibration transfer techniques: Direct Standardization, Piece-wise Direct Standardization, Orthogonal Signal Correction and Generalized Least Squares Weighting. In order to evaluate the performance of the calibration transfer, we compare the Root Mean Square Error of Prediction (RMSEP) of master and slave arrays, for each instrument correction. Best results are obtained from Piece-wise Direct standardization, which exhibits the lower RMSEP values after correction for the smaller number of transfer samples. (C) 2016 Elsevier B.V.

(2018) Nguyen, N.M.P.; Ge, Z.-J.; Reddy, R.; Fahiminiya, S.; Sauthier, P.; Bagga, R.; Sahin, F.I.; Mahadevan, S.f; Osmond, M.; Breguet, M.; Rahimi, K.; Lapensee, L.; Hovanes, K.; Srinivasan, R.; Van den Veyver, I.B.; Sahoo, T.; Ao, A.; Majewski, J.; Taketo, T.; Sim, R.; 0000-0001-7308-9673; 30388401; AAC-7232-2020
Androgenetic complete hydatidiform moles are human pregnancies with no embryos and affect 1 in every 1,400 pregnancies. They have mostly androgenetic monospermic genomes with all the chromosomes originating from a haploid sperm and no maternal chromosomes. Androgenetic complete hydatidiform moles were described in 1977, but how they occur has remained an open question. We identified bi-allelic deleterious mutations in MEI1, TOP6BL/C11orf80, and REC114, with roles in meiotic double-strand breaks formation in women with recurrent androgenetic complete hydatidiform moles. We investigated the occurrence of androgenesis in Mei1-deficient female mice and discovered that 8% of their oocytes lose all their chromosomes by extruding them with the spindles into the first polar body. We demonstrate that Mei1−/− oocytes are capable of fertilization and 5% produce androgenetic zygotes. Thus, we uncover a meiotic abnormality in mammals and a mechanism for the genesis of androgenetic zygotes that is the extrusion of all maternal chromosomes and their spindles into the first polar body. © 2018 American Society of Human Genetics

(2021) Ilikkan, Ozge Kahraman; Bagdat, Elif Seyma; 0000-0001-5843-6868; Q-9641-2019
Kefir is a health-promoting fermented drink having complex microbiota. This complex microbiota consists of bacteria and yeast association that is bound together with a polysaccharide called kefiran. To date, the complex microbiota of fermented foods was enlightened with culture-depended methods, however, recently, metagenomic studies have been started to use to reveal microbial diversity of fermented foods such as kefir. In this present study, we investigated the microbiome of two artisanal Turkish kefir grains (namely, A and G) by high throughput sequencing at the species level. Additionally, physicochemical analyses were carried out besides enumerations of lactobacilli, lactococci, total aerobic, and bifidobacteria in fermented milk kefirs. In these two kefir grains, different bacterial and fungal populations were revealed. In kefir grain A, Bifidobacterium longum was the dominant species while in kefir grain G, Lactobacillus kefiranofaciens was dominant. Concerning fungal diversity, in kefir grain A, Naumovozyma dairensis was the dominant yeast, while in kefir grain G, Zygosaccharomyces rouxii was dominant. High-throughput sequencing studies have revealed that kefir grains were typically dominated by lactobacilli. But, in this study, Bifidobacterium longum was found as a dominant bacterium in kefir for the first time.

(2022) Kahraman-Ilikkan, Ozge; https://orcid.org/0000-0001-5843-6868; 35763226; Q-9641-2019
The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas systems constitute the adaptive immune system in prokaryotes that provide resistance against invasive genetic elements. The genus Propionibacterium comprises gram-positive, facultative anaerobe, non-spore-forming bacteria, and is the source of some B group vitamins such as B12 as well as bacteriocins. Some of the selected species of the genus Propionibacterium spp. were reclassified into the three genera in 2016 (Acidipropionibacterium spp., Pseudopropionibacterium spp., Cutibacterium spp.). Therefore, this study compared CRISPR/Cas systems, Cas 1 and repeat sequences phylogeny, phage/plasmid surveys as well as insertion sequences of new genera members. In this study, a total of 34 genomes of 13 species were observed with a bioinformatic approach. CRISPR-Cas + + and CRISPRDetect were used to detect CRISPR/Cas systems, direct repeats, and spacers. 39 CRISPR-Cas systems were detected. Type I-E, Type I-U, and one incomplete III-B CRISPR-Cas subtypes were identified. Most of the strains had Cas1/Cas4 fusion proteins. Pseudopropionibacterium propionicum strains had two types I-U and one of the CRISPR loci had csx17 cas genes. Common phage invaders were Propionibacterium phage E6, G4, E1, Anatole, and Doucette. The BLSM62 similarity score of all Cas1 sequences was 48.4% while the pairwise identity of repeat sequences was 48.7%. Common insertion sequences were ISL3, IS3, IS30. The diversity analysis of the CRISPR/Cas system in the genus Propionibacterium provided a new perspective for determining the role of the CRISPR-Cas system in the evolution of new genera.

(2019) Cansu-Ergun, Emine Gul; 0000-0002-3941-4345; I-7385-2017
An electrochromic copolymer film of 2-(3,3-dihexyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-6-yl)-7-(3,3-dihexyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepin-8-yl)-9H-carbazole (M1) and 4,7-bis(thiophen-2-yl)benzo[c][1,2,5]thiadiazole (M2) was prepared via electrochemical technique. The copolymerization was performed with one to one monomer feed ratio. Electrochemical and optical properties of the resulting copolymer film (P3) and the homopolymer films of M1 and M2 (P1 and P2) were investigated by using cyclic voltammetry and UV-Vis spectrometry techniques, and the corresponding results were compared. Incorporation of M1 and M2 into copolymer matrix was clearly observed on the resulting cyclic voltammograms and UV-Vis spectra. P3 covered the visible regions coming from both P1 and P2, and exhibited a neutral state darker color than those of homopolymers. P3 film was found to have a multichromic behavior, appearing as brown in its neutral state while changing its color upon oxidation to dark-gray (at about 0.3 V), to blue (at about 0.6 V) and finally to grayish cyan (beyond 0.9 V), with a corresponding optical band gap of 1.65 eV.

(2019) Guney, Selda; Erdas, Cagatay Berke; 0000-0002-0573-1326; 0000-0003-3467-9923; AAC-7404-2020
Since 1990s, activity recognition effectual field in machine learning literature. Most of studies that relevant activity recognition, use feature extraction method to achieve higher classification performance. Moreover, these studies mostly use traditional machine learning algorithms for classification. In this paper, we focus on a deep (Long Short Term Memory) LSTM neural network for feature free classification of seven daily activities by using raw data that collected from three-dimensional accelerometer. Based on the results, the proposed deep LSTM approach can classify raw data with high performance. The results show that the proposed deep LSTM approach achieved 91.34, 96.91, 88.78, 87.58 as percent classification performance in terms of accuracy, sensitivity, specificity, F-measure respectively.
The Effect Of Kefir Enrichment With Arthrospira Platensis And Chlorella Vulgaris On Kefir Microbiota, Antioxidant, And Physicochemical Properties
(2022) Kahraman Ilikkan, Ozge; Bagdat, Elif Seyma
This study evaluated the effect of Arthrospira platensis and Chlorella vulgaris on kefir microbiota, total phenolic content, antioxidant activity, and physicochemical properties such as pH, Brix, total dry matter, and titratable acidity. The results showed that the addition of algae at concentrations of 0.5% (w/v) and 1% (w/v) to the kefir did not change the acceptable physicochemical properties of kefir. The acidity of the microalgae-enriched kefirs increased with increasing algae concentration. Total phenolic content and antioxidant activity of all kefir samples fortified with algae were higher than those of the control. However, the addition of A. platensis exhibited better prebiotic activity than C. vulgaris on kefir microbiota during storage. Principal component analysis and overall results showed that A. platensis was a better candidate for improving the nutritional value of kefir.
The Effects of Audience's Attitudes on Actor, Character, Movie and Product Placement on the Brand Attitude
(2020) Ulker-Demirel, Elif; Yildiz, Erkan
In recent years, there has been a shift in consumers' media consumption preferences from traditional to digital platforms. Adblocker applications used by consumers who do not want to be exposed to advertising and the digital platforms that offer ad-free content make it increasingly difficult for brands to reach audiences in a highly saturated advertising environment. In this environment, product placement remains essential in reaching the target audiences due to the advantages it offers to brands compared to traditional advertisements. The aim of this study, being distinctly different from previous research, is to test the effects of attitude toward actor and character on attitude toward movies, product placement, and brand. Furthermore, it is aimed to investigate the serial mediating effect between these attitudinal constructs. The data obtained from 300 participants were analyzed with SmartPLS 3.2.8 using partial least squares path analysis (PLS-SEM). As a result, the attitude toward the actor, character, and movie has direct and indirect effects on product placement and attitude toward the brand. Furthermore, the effect of the attitude toward movies and product placement has a serial mediating effect on the relationship between the attitude toward the actor, the character and the brand.
The Effects of Using Artificial Intelligence and Robotics in Logistics Service Production: An Application in 3pls and 4pls
(2023) Caglar, Macide Berna; Taskin, Bihter Karagoz
Background: The purpose of this study is to investigate how artificial intelligence (AI) and robotic awareness, perceived organizational support, and competitive psychological climate approaches relate to turnover intention. In the literature, studies on robotic awareness and turnover intention have been undertaken in a variety of industries. In this respect, this study aims to address the absence in the literature of research on logistics services providers. This study aims to help businesses understand how to retain employees and foster a more inclusive and supportive workplace.Methods: The study utilizes survey information from 100 senior managers in the operations function of logistics service providers. The outcomes are obtained by modeling structural equations with SmartPLS. Data from the survey were gathered using the snowball sampling technique.Results: The results of the research reveal the effect of artificial intelligence and robotic awareness on competitive psychological and turnover intention.Conclusions: The study aims to explore the role of a competitive psychological climate and organizational support in mediating the relationship between AI and robotics awareness and turnover intention. We identify that awareness of AI and robotics has a considerable, favorable effect on the psychological climate of competition and turnover intention. We also find that the competitive psychological atmosphere has a substantial, favorable effect on turnover intention. In addition, organizational support has been demonstrated to have a substantial, favorable effect on turnover intention. However, it was not possible to identify the mediating role of organizational support and the psychological environment of competition in moderating the association between awareness of AI and robotics and turnover intention. On the basis of the research's findings, suggestions were made.
An Efficient Approach For Sub-Carrier Allocation In MIMO MC-CDMA Systems
(2022) Seyman, Muhammet Nuri; Demiral, Bircan
Sub-carrier allocation is an important process that directly affects users data and bit error rates for multi-user multi-carrier systems. The most important feature of the allocation process is to assign the sub-carriers to the active users in proportion to their needs to provide high-speed data transmission and reduce the bit error rates. In this study, an efficient subcarrier allocation algorithm has been proposed based on both capacity and fairness criteria for a MIMO MC-CDMA system, which is preferred as the multiplexing scheme in high data rate communication systems. The proposed algorithm achieves not only better error rate performance but also increases the total data rate compared to other algorithms
Fetal HLA-G alleles and their effect on miscarriage
(2018) Kubat, Gozde; Koc, Altug; Kirbiyik, Ozgur; Kutbay, Yasar B.; Ozyilmaz, Berk; Ozdemir, Taha R.; Kaya, Ozge Ozer; Koc, Zeynep Peker; 29809322
Background. Immunosuppression at the feto-maternal interface is crucial for a successful pregnancy outcome. Human leukocyte antigen-G (HLA-G) seems to be a major contributor to fetal tolerance. The HLA-G expression is seen in cytotrophoblasts and in maternal blood. Fetal HLA-G acts on decidual antigen-presenting cells (APCs), natural killers (NKs) and T cells. Recent findings revealed that defects in placentation and their consequences are associated with maternal HLA-G variants and their expression levels. Objectives. The objective of this article is to investigate the relationship between fetal HLA-G alleles and miscarriage, which has not been investigated to date. Material and methods. The present study includes 204 recurrent miscarriage (RM) cases who were admitted to our clinic between 2012 and 2016. Twenty-eight miscarriage products without maternal cell contamination and any known pathology were analyzed by HLA-G typing. In addition, 3' untranslated region (UTR) 14-base pair (bp) insertion/deletion polymorphism was also investigated by Sanger sequencing. Results. For our population, the most frequent HLA-G type was G*01:01, both in the study group (30.3%) and in the control group (47%). The study revealed that the G*01:04 allele was significantly associated with miscarriage (p = 0.007). The 3' UTR 14bp deletion was more frequent in the miscarriage group, but there was no significant correlation. Conclusions. HLA-G alleles seem to be related with miscarriage and should be considered in RM cases.
Genome composition analysis of multipartite BNYVV reveals the occurrence of genetic re-assortment in the isolates of Asia Minor and Thrace
(2020) Ozmen, Canan Yuksel; Khabbazi, Saber Delpasand; Khabbazi, Afsaneh Delpasand; Gurel, Songul; Kaya, Riza; Oguz, Muhammet Cagri; Turan, Ferzat; Rezaei, Fereshteh; Kibar, Umut; Gurel, Ekrem; Ergul, Ali; 32139777
Beet necrotic yellow vein virus (BNYVV) is the cause of rhizomania, an important disease of sugar beet around the world. The multipartite genome of the BNYVV contains four or five single-stranded RNA that has been used to characterize the virus. Understanding genome composition of the virus not only determines the degree of pathogenicity but also is required to development of resistant varieties of sugar beet. Resistance to rhizomania has been conferred to sugar beet varieties by conventional breeding methods or modern genome engineering tools. However, over time, viruses undergo genetic alterations and develop new variants to break crop resistance. Here, we report the occurrence of genetic reassortment and emergence of new variants of BNYVV among the isolates of Thrace and Asia Minor (modern-day Turkey). Our findings indicate that the isolates harbor European A-type RNA-2 and RNA-3, nevertheless, RNA-5 is closely related to East Asian J-type. Furthermore, RNA-1 and RNA-4 are either derived from A, B, and P-types or a mixture of them. The RNA-5 factor which enhance the pathogenicity, is rarely found in the isolates studied (20%). The creation of new variants of the virus emphasizes the necessity to develop new generation of resistant crops. We anticipate that these findings will be useful for future genetic characterization and evolutionary studies of BNYVV, as well as for developing sustainable strategies for the control of this destructive disease.
Metataxonomic Sequencing To Assess Microbial Safety Of Turkish White Cheeses
(2022) Kahraman-Ilikkan, Ozge; Bagdat, Elif Seyma; https://orcid.org/0000-0001-5843-6868; 35277850; Q-9641-2019
High-throughput sequencing has provided a way to monitor the large diversity of microorganisms in fermented foods that have complex microbiota. Up to date, many kinds of cheese have been characterized with the metataxonomic approach, but the safety of unpacked Turkish white cheeses, which are widely consumed in Turkey, has not been assessed. In this study, fifteen unpacked white cheeses sold in public bazaars in Ankara province have been collected and subjected to microbial enumeration as well as physicochemical analysis. Five white cheeses, which have relatively the highest foodborne pathogens, out of fifteen white cheeses, have been analyzed by next-generation sequencing and metataxonomic analysis. According to the results, abundant families were Lactobacillaceae, Oceanospirillaceae, Enterococcaceae, Pseudomonadaceae, and Vibrionaceae. Staphylococcus aureus, E. coli, and Salmonella, which are indicators of bad hygiene and sanitation conditions, were found in cheeses. In conclusion, culture-independent methods such as metataxonomic can be important to evaluate the safety of foods.
NUMERICAL STABILITY OF RBF APPROXIMATION FOR UNSTEADY MHD FLOW EQUATIONS
(2019) Gurbuz, Merve; Tezer-Sezgin, M.
In this study, the radial basis function (RBF) approximation is applied for solving the unsteady fluid flow and magnetohydrodynamic (MHD) convection flow problems with the use of explicit Euler time discretization and relaxation parameters to accelerate the convergence. The stability analysis is also carried out in terms of the spectral radius of related RBF discretized coefficient matrices. The optimal choices of the time increment, relaxation parameters and physical problem parameters are found for achieving stable solutions. It is observed that the maximum eigenvalues of the coefficient matrices decrease with an increase in the time increment when the relaxation parameters are decreasing. Although the time derivative is discretized using explicit Euler method, one does not need to use small time increment for obtaining stable results. The flow, isotherms and pressure behaviors are simulated at steady-state for several values of problem parameters using time increment and relaxation parameters which lead to stable solutions.

Pulse frequency fluctuations of magnetars
(2019) Cerri-Serim, D.; Serim, M. M.; Sahiner, S.; Inam, S.C.; Baykal, A.; 0000-0003-0820-9186
Using RXTE, Chandra, XMM-Newton and Swift observations, we construct the power spectra and torque noise strengths of magnetars for the first time. For some of the sources, on time-scales of months to years, we measure strong red noise that might be a consequence of their outbursts. We compare the noise strengths of magnetars with those of radio pulsars by investigating the possible correlations of noise strength with spin-down rate, magnetic field and age. Using these correlations, we find that the noise strengths of magnetars obey similar trends as radio pulsars. However, we do not find any correlation between noise strength and X-ray luminosity, a correlation that has been seen in accretion-powered pulsars. Our findings suggest that the noise behaviour of magnetars resembles that of radio pulsars, but magnetars possess higher noise levels likely because of their stronger magnetic fields.

Status of the Albanian Muslims in Greece During the Population Exchange on the Basis of the Minutes of Lausanne Conference and the Reports of the Embassy of Albania in Athens
(2017) Ozcan, Halil
The Subcommittee of Population Exchange at Lausanne Conference addressed the exchange topic in twelve sessions between January, 11, 1923 and January 30, 1923. The convention and protocol concerning the exchange between populations of two countries were signed on January 30, 1923 by the Turkish and Greek Governments. Accordingly, it was decided to conduct compulsory population exchange between the "Turkish nationals of Greek Orthodox religion" who had domiciled in Turkish territories and the "Greek nationals of Muslim religion" who had domiciled in Greek territories. Despite Greece provided all assurances at Lausanne Conference and afterwards, it took action to exchange the Albanian Muslims, who lived in Epirus-Chameria region where almost all of the population was Muslim with the immigrant Greeks who came from Anatolia, due to the fact that the Albanian Muslims were "Greek nationals with Muslim religion." During this period, Mid'hat Frasheri was assigned to the Embassy of Albania in Athens on January 1923. The Ambassador discussed the situation of the Albanian Muslims in Greece, with the authorities, the League of Nations, the Mixed Exchange Committee, the Turkish authorities and mainly the Greek authorities. Mid'hat Frashri sent approximately 200 reports, which included these discussions to the Albanian Ministry of Foreign Affairs.
