(Soc Chilena Anatomia, 2024) Soyler, Mehmet; Zileli, Raif; Ozkamci, Huseyin; Diker, Gurkan; Sever, Mehmet Onur; Bayrakdaroglu, Serdar; On, Sadi
The aim of this study is twofold: (1) to identify differences in certain anaerobic parameters (10m sprint, 30m sprint, anaerobic power, and Illinois agility tests) between professional and amateur soccer players, and (2) to determine whether there is a difference in the ACTN3 gene polymorphism between professional and amateur soccer players. Ultimately, the goal is to reveal which parameters contribute to the differentiation in these two aspects. A total of 133 volunteer soccer players, including 71 professionals and 62 amateurs, participated in the research. DNA extraction from buccal epithelial cells was performed using a commercial kit to determine the genetic background of the athletes, and Real -Time PCR was conducted for genotyping. Statistical analysis of the findings obtained from the test results was performed using the SPSS 23 (SPSS Inc., Chicago, IL, USA) package program. The homogeneity of variance of the data was assessed using the Levene Test, and normal distribution analyses were conducted using the Shapiro -Wilk Test. Chi-square and Mann -Whitney U tests were employed for parameter analysis. The significance level was set at p<0.05. Evaluation of the data in our study revealed no statistically significant difference in ACTN3 rs1815739 gene polymorphism between the groups (p>0.05). However, there is a statistically significant difference in anaerobic parameters (10m sprint, 30m sprint, and anaerobic power) except for the Illinois test (p<0.05). In conclusion, our study found that gene polymorphism is not a differentiating factor between professional and amateur soccer players, but speed (10m and 30m) and anaerobic power parameters are differentiating factors.
The Distinguishing Factor in Soccer Players is Aerobic Performance, not the ACTN3 Gene
(Soc Chilena Anatomia, 2023) Zileli, Raif; Soyler, Mehmet; Diker, Gurkan; Ozkamci, Huseyin; Bayrakdaroglu, Serdar; Sever, Mehmet Onur; Can, Ibrahim
The purpose of this study was to reveal the differences between ACTN3 genotype (RR, RX, XX) and aerobic performance [Yo-Yo IRT1 (m), VO2 max (ml/kg/min)] in professional and regional amateur league soccer players and to reveal which of these parameters was a distinctive factor in these athletes.71 professional soccer players (age: 23.66 +/- 4.11 years; body height: 1.79 +/- 6.99 m; body weight: 76.02 +/- 6.76 kg; body fat: 11.59 +/- 3.11 %) and 62 regional amateur soccer players (age: 23.63 +/- 3.77 years; body height: 1.81 +/- 5.77 m; body weight: 76.36 +/- 7.53 kg; body fat: 15.60 +/- 4.65 %) volunteered for the study. After DNA extraction from buccal epithelial cells via a commercial kit was performed for the genetic background of the athletes, Real-Time PCR was carried out for genotyping. Furthermore, Yo-Yo IRT1 test was performed to determine the aerobic performance of the soccer players. SPSS 23 (SPSS Inc., Chicago, IL, USA) package program was used for the statistical analysis of the data obtained in the tests. Shapiro-Wilk test for normality and Levene's test for homogeneity of variance were performed. Chi-Square, Independent Sample T Test and One Way ANOVA test were used in the analysis of the parameters. Statistical significance was set as p<0.05. In the study, there found no meaningful statistical significance in terms of the rs1815739 polymorphism in the ACTN3 gene between the groups (p>0.05); however, there was a statistical significance in favor of professional soccer players in terms of aerobic parameters (p<0.05). Consequently, it can be said that aerobic performance is the distinguishing factor, not the ACTN3 gene, in soccer players.
A CASE STUDY: ECOLOGICAL QUALITY STATUS OF SUSURLUK RIVER BASIN (MARMARA SEA)
(Parlar Scientific Publications (P S P), 2019) Albayrak, Serhat; Caglar, Senem; Mulayim, Aysegul; Kurt-Sahin, Guley; Balkis, Husamettin; Cinar, Nur Findik; Atabay, Hakan
This study was carried out with the aim of determining the Ecological Quality Status (EQS) of coastal transitional waters of Susurluk River Basin (Marmara Sea). Macrozoobenthic invertebrate material was collected in May of 2013 from six stations in triplicate by means of a van Veen grab. Shannon-Weaver Diversity Index and associated Pielou's Evenness Index together with biotic indices AMBI and BENTIX were calculated. Some ecological variables (Secchi disc depth, temperature, salinity, dissolved oxygen, pH, total phosphorus, total nitrogen, silica, Chlorophyll-a) of the sea water and total organic carbon of the sediment were also measured. Ecological Quality Status at each station was assessed by considering individual dominancy of sensitive and tolerant species, results from univariate/biotic indexes and some ecological parameters. When EQS of the basin is evaluated as a whole, it was seen that there was not any station in Good or High EQS at the study area, stations were in Poor or Bad EQS at the stations where the River meets the sea, while the stations off the River mouth were in Moderate EQS. Both species pattern of macrozoobenthic invertebrate communities and ecological parameters determined in the basin such as TOC and nutrients present the negative impacts of the River over the basin and indicate the necessity of efficient precautions to be taken.
THE EFFECT OF DIMETHOATE ON CAPOETA CAPOETA (GULDENSTAEDT 1773) AND THE PROTECTIVE EFFECT OF ASCORBIC ACID
(Parlar Scientific Publications (P S P), 2016) Tanriverdi, Erdi Anil; Yilmaz, Muhitdin; Koc, Evren; Akgul, Ali; Ersan, Yusuf
In this study, Dimethoate (DM) (a pesticide)'s histopathological and electrophoretic effects were investigated on Capoeta capoeta (Guldenstaedt 1773) that were captured from Kars creek, and the protective effect of ascorbic acid (AA) (vitamin C) was tested. After allowing time for their adaptations to their new environment, the fish caught from Kars creek were divided into 4 groups (each including 10 fish), and placed in 300-liter tanks in the laboratory. The fish were kept in water containing different solutions: group I in normal water medium, group II in 100 mg/L AA, group III in 2 mg/L DM, and group IV in 100 mg/L AA and 2 mg/L DM. They were kept in these water mediums for 10 days. After this period, blood and tissue samples were taken from the fish for electrophoretic and histopathological studies. Tissue samples were detected in 10% formaldehyde solution and paraffin blocks were prepared by routine histological methods. The samples were cut into sections 3-5 thick, all stained according to hematoxylin and eosin staining methods, and they were examined under a microscope. Obtained serum samples were carried out in Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE). When we compared the serum samples with the control group of fish, protein bands in the application of 100 mg/L AA and 2 mg/L DM, thickening in 36 kD band, thinning in 100 kD, 97 kD, 76 kD, 56 kD and 30 kD bands were observed, and the bands of 93 kD, 46 kD, 44 kD and 26 kD were detected as newly-synthesized in SDS-PAGE electropherogram. In the histopathological examinations, depending on DM in intestine, liver, and kidney tissues obtained from the group formed by application of DM and AA, degeneration, necrosis, pyknotic nuclei and cell infiltrates were detected. As a result, whereas DM application was found to create toxic effects on Capoeta capoeta, AA was found to have a healing effect.
Voltammetric Determination of Hydroxylamine Using a Ferrocene Derivative and NiO/CNTs Nanocomposite Modified Carbon Paste Electrode
(Esg, 2015) Golestanifar, Fereshteh; Karimi-Maleh, Hassan; Atar, Necip; Aydogdu, Ercan; Ertan, Bengu; Taghavi, Mehdi; Yola, Mehmet Lutfi
The electrochemical activities of hydroxylamine (HX) as a pollutant compound at a 1,1-bis(phenylacetyl) ferrocenele/NiO/CNTs modified carbon paste electrode (1,1-BPF/NiO/CNTs/CPE) has been studied. 1,1-BPF was used as a suitable mediator for elecrocatalytic interaction with HX. The voltammetric properties of HX at the 1,1-BPF/NiO/CNTs/CPE was investigated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), chronoamperometry, and square wave voltammetry (SWV) methods. The oxidation peak current increases linearly with HX concentration in the range 0.5-250.0 mu M and the detection limit for HX was 0.2 mu M. The sensor was applied to wastewater samples with excellent performance.
Plantago major Protective Effects on Antioxidant Status after Administration of 7,12-Dimethylbenz(a)anthracene in Rats
(Asian Pacific Organization Cancer Prevention, 2011) Oto, Gokhan; Ekin, Suat; Ozdemir, Hulya; Demir, Halit; Yasar, Semih; Levent, Abdulkadir; Berber, Ismet
Aim: The present study was designed to evaluate effects of Plantago major extract on oxidative status in Wistar albino rats administrated 7,12-dimethylbenz(a)anthracene (DMBA). Methods: Rats were divided into three equal groups of 6 animals each: Group 1 controls, group 2 treated with DMBA (100 mg/kg, single dose) and group 3 receiving the DMBA and the aqueous extract at 100 mg/kg/d for 60 days. Results: Significant decrease in catalase (P<0.05), carbonic anhydrase (p <= 0.01), reduced glutathione (GSH) (P<0.01) and total protein (P<0.01) values was observed in the DMBA group compared with the healthy controls and DMBA + Plantago major groups. Conclusion: The results suggest preventive effects of Plantago major on DMBA induced oxidative damage in Wistar albino rats that might be due to decreased free radical generation.

(Chinese Journal Structural Chemistry, 2013) Khan, Islam Ullah; Arshad, Muhammad Nadeem; Sahin, Onur; Mubashar-Ur-Rehman, Hafiz; Munir, Ayesha; Humayun, Saba; Asiri, Abdullah M.
The title compounds, C12H10N3O7SCl (I) and C15H27NO3S (II), crystallize in the monoclinic system, space group P2(1)/c with a = 7.3995(1), b = 27.8489(6), c = 9.8246(2) angstrom, beta = 131.349(1)degrees, V = 1519.82(5) angstrom(3), Z = 4, F(000) = 768, R-int = 0.033 and S = 1.03 for I, and in the orthorhombic system, space group Pbca with a = 8.6227(1), b = 16.1480(4), c = 23.8774(6) angstrom, V = 3324.67(12) angstrom(3), Z = 8, F(000) = 1312, R-int = 0.024 and S = 1.04 for II. We have devised a convenient procedure for the synthesis of fused organic salts resulting from 1:1 proton-transfer, using an amine and a derivative of benzenesulfonic acid. The synthesized salts have a number of applications ranging from their consumption as eco-friendly solvents and catalysts in organic syntheses, to being used as efficient precursors for the production of sulfa drugs. Structures of compounds 3-chloroanilinium 2,4-dinitrobenzenesulfonate (CA-DNBS) and triethylaminium 2,4,6-trimethylbenzenesulfonate (TEA-TMBS) were determined by single-crystal X-ray diffraction studies and infrared spectroscopy.
The first record of karyotypes in Leiurus abdullahbayrami and Compsobuthus matthiesseni (Scorpiones: Buthidae) from Turkey
(Univ Oradea Publ House, 2014) Stahlavsky, Frantisek; Koc, Halil; Yagmur, Ersen Aydin
The karyotypes of Leiurus abdullahbayrami Yagmur, Koc & Kunt, 2009 and Compsobuthus matthiesseni (Birula, 1905) from Turkey are presented for the first time. Both analyzed species have achiasmatic meiosis and the same number of holocentric chromosomes (2n=22) gradually decreasing in size. During the first meiotic division we observed tetravalent in one male of L. abdullahbayrann and octovalent in one male of C. matthiesseni. These types of multivalents may increase genetic variability and indicate reciprocal translocations within these species.
Synthesis, Crystal Structure and Theoretical Characterization of (3R, 4R, 6S)-3,6-Dihydroxy-1-Menthene Isolated from Echinophora Tenuifolia
(Gazi Univ, 2016) Celik, Ismail; Ersanli, Cem Cuneyt; Akkurt, Mehmet; Aksit, Huseyin; Erenler, Ramazan
In the title compound, C10H18O2, the cyclohexene ring adopts a half-chair conformation. In the crystal strcuture, weak inter(sic)molecular O-H center dot center dot center dot O hydrogen bonds connect the adjacent molecules, forming edge-fused R23(8) ring motifs, into the hollow columns parallel to the b-axis direction. The crystal packing is governed only by van der Waals inter(sic)actions. There is no further C-H center dot center dot center dot pi and pi-pi interactions. The H atom in one of two hydroxyl groups was found to be disordered over two sites. The occupancy factors of the two sites were refined to 0.52 (2) and 0.48 (2). Semi-empirical PM3 quantum chemical calculations are in satisfactory agreement with the results of the X-ray structure analysis.

(Bangladesh Botanical Soc, 2021) Demir, Cemile Cansi; Ozler, Hulya; Kaplan, Ayse
This study was conducted for determining the plant taxa of the pollen grain in the atmosphere of the city center of Sinop (Turkey) and investigating the effects of meteorological factors on pollen concentration, by analyzing daily, weekly and monthly changes in the atmosphere. The types and amounts of pollen grain in the atmosphere were determined using Burkard trap. On the basis of the average of 2 years (2016 - 2017), the dominant trees taxa in the atmosphere were Cupressaceae/Taxaceae (32.67%), Pinaceae (15.51%), Morus sp. (5.50%), Quercus sp. (2.76%), Alnus sp. (2.24%), Corylus sp. (1.48%), Carpinus sp. (1.43%), Juglans sp. (1.43%), Fraxinus sp. (1.33%), Olea europaea (1.05%) and Poaceae (Grass) (5.29%), whereas the dominant weed taxa were Urticaceae ( 11.16%), Ambrosia sp. (4.31%), Amaranthaceae (3.21%), and Mercurialis sp. (2.05%). Temperature and wind speed had a positive effect on the increased amount of pollen, whereas precipitation had a negative effect on it. On the basis of the data obtained, a pollen calendar was prepared for the area.
Evaluation of diffuse lymphadenopathy via various quantitative PET/CT parameters
(Hellenic Soc Nuclear Medicine, 2023) Silov, Guler; Cankaya, Emel; Karacavus, Seyhan
Objective: Discovery of diffuse lymphadenopathy (DLAP) in fluorine-18-fluorodeoxyglucose ( F-18-FDG) positron emission tomography/computed tomography (PET/CT) imaging alerts for the existence of many pathologic conditions with severity ranging from benign to malignancy. This study examines the role of various metabolic parameters reflecting F-18-FDG characteristics of organs/tissues to reach an accurate differential diagnosis for further clinical assessment. Materials and Methods: Positron emission tomography/CT images of 78 patients with DLAP were reviewed retrospectively. The diameter of the largest lymph node (DLlyn), maxi- mum standardized uptake value (SUVmax) of the liver (L), the largest lymph node (Llyn), spleen (S), and bone marrow (BM) were measured. Ratios to liver SUVmax were calculated for all, resulting LLRmax, SLRmax, and BMLRmax respectively. Results: The diameter of the largest lymph node, Llyn. SUVmax, LLRmax, and SLRmax produced cut-off values as 25.5, 8.86, 2.80, and 0.82 with corresponding sensitivity: specificity values as 65%:83%, 74%:77%, 74%:71%, and 79%:63% respectively for risk stratification of malignant causes. To differentiate lymphoma from sarcoidosis, DLlyn, SLRmax, and BMLRmax were found valuable with cut-off values obtained as 28.5, 0.84, and 1.19 with corresponding sensitivity: specificity values as 79%:91%, 79%:82%, and 54%:91%, respectively. Interdependency between parameters was also evaluated. Conclusion: High values of Llyn. Maximum SUV and LLRmax are the main characteristics of lymphoma, metastasis, and sarcoidosis. The diameter of the largest lymph node, SLRmax, and BMLRmax are determined as distinct parameters for distinguishing lymphoma from sarcoidosis. Besides, observed correlation structures amongst some PET/CT parameters were identified as nodal, extranodal, and diffuse patterns for three disease groups except sarcoidosis. These findings extend the knowledge about diagnostic factors based on F-18-FDG PET/CT patterns for DLAP.
Electrical characteristics of atomic layer deposited Au/Ti/Al2O3/n-GaAs MIS structures over a wide measurement temperature
(Natl Inst Optoelectronics, 2017) Turut, A.; Karabulut, A.; Efeoglu, H.
We have prepared the Au/Ti/Al2O3/n-GaAs structures and investigated their current-voltage (I-V) characteristics with the temperature (in 20-320K range) as a parameter, and current-temperature (I-T) characteristics with bias voltage as a parameter. The ultrathin Al2O3 metal-oxide layer on the n-GaAs substrate has been formed by atomic layer deposition (ALD) method. Ti(10nm) rectifying contacts have been fabricated on Al2O3/n-GaAs structure by DC magnetron sputtering. The ideality factor value has remained between 1.10-1.06 from 130 K to 320 K. The barrier height (BH) value has increased with a slope of alpha = -0.31 meV/K from 320 K to 110 K. Then, it has been seen that the decrease in the BH value from 110 K to 20 K obeys a double Gaussian distribution (GD) of the BHs due to the BH inhomogeneity. The experimental I-T characteristics have been interpreted by plotting the theoretical I-T characteristics with and without the GD based on the TE current theory at each bias voltage. Moreover, the BH values have been also determined from the Richardson curves plotted using the I-T data at each forward and reverse bias voltage. It has been observed that the BH reduction is higher under reverse bias voltage than under forward bias voltage regime due to the barrier inhomogeneity which is not recommended for the Schottky diode being a rectifying device.
Real Time Heart Rate Detection Using Non-Contact Photoplethysmography Signals
(Ieee, 2014) Kavsaoglu, Ahmet Resit; Polat, Kemal; Bozkurt, Mehmet Recep
Heart is contracted rhythmically so as to drive nutrients and oxygen necessary for life through our organs with blood arteries. The frequency for the rhythmic contraction of heart just as a pump is called heart rate (HR). Heart rate variation (HRV) is a measure of a fluctuation of time interval between heart beats. HRV is calculated considering electrodiagram (ECG) signals, arterial blood pressure signals or photoplethysmography (PPG) signals-derived time series of in-between heart beats. HRV is used as a significant indicator for the detection of healthiness and sickness state. Such pathological cases as high blood pressure, heart failure, and septic shock can be diagnosed using HRV. Therefore, accurate and rapid detection of HR is essential to correct diagnosis. In this study, real-time heart rate detection was derived from contactless PPG signals. PPG calling for contact with skin becomes useless in case of tissue scars or burns. In such cases, the use of contactless PPG is superior. Contactless PPG consists of a light source and a camera that senses reflection or transmittance of the light source. Camera images obtained were processed through an interface prepared in the MATLAB (TM) GUI setting, and real-time heart rate detection was carried out.
Electrochemical Sensor Based on Graphene Oxide/Iron Nanoparticles for the Analysis of Quercetin
(Esg, 2015) Akyildirim, Onur; Medetalibeyoglu, Hilal; Manap, Sevda; Beytur, Murat; Tokali, Feyzi Sinan; Yola, Mehmet Lutfi; Atar, Necip
We aimed a novel electrochemical sensor based on iron nanoparticles (FeNPs) and 2-aminoethanethiol (2-AET) functionalized graphene oxide (2-AETGO). The methods such as transmission electron microscope (TEM), scanning electron microscope (SEM), x-ray photoelectron spectroscopy (XPS), reflection-absorption infrared spectroscopy (RAIRS), electrochemical impedance spectroscopy (EIS) and the x-ray diffraction (XRD) method were used for the characterizations of nanocomposites. The linearity and the detection limit of quercetin (QR) were 1.0x10(-8) - 1.0x10(-7) M and 2.0x10(-9) M, respectively. The modified glassy carbon electrode (FeNPs/2-AETGO/GCE) was applied to the determination of QR in food sample such as apple juice.
BIOCHEMICAL EFFECTS OF ARSENIC STRESS IN THE LEAVES OF HALOPHYTE Cakile maritima (SCOP.) PLANTS UNDER SALINITY
(Parlar Scientific Publications (P S P), 2013) Demir, Emel; Dinler, Burcu Seckin; Ozdener, Yasemin
The aim of the study was to determine the biochemical responses which were not investigated before, the combined effects of arsenic and salt stress in the leaves of Cakile maritima (Scop.). Therefore, product of lipit peroxidation (MDA, malondialdehyde), proline content, nonprotein thiol, ascorbate, dehydroascorbate and the activity of some antioxidant enzymes as ascorbate peroxidase (APX, EC 1.11.1.11), catalase (CAT, EC 1.11.1.6) were reported. The MDA content was increased at 24 h but it was more at 96 h under salt stress alone. Otherwise the combined effect of arsenic and salt stress increased the malondialdehyde content at 24 h more than salt stress alone. APX activity was not changed under all treatment while CAT enzyme was decreased at 24 h. The proline content was increased only at 96 h under salt stress alone while it did not change under arsenic and salt stress. Nevertheless, the ascorbate content was not changed under all treatments. The ratio of ascorbate/dehydroascorbate was decreased at 24 h but not significiantly at 96 h under salinity. Otherwise it was decreased at 24 h and increased at 96 h under arsenic and salt treatment lead to reduction of the increased MDA content according to 24 h. From these results, it can be suggested that salinity with arsenic stress induced oxidative damage more seriously than salt stress alone with unchanged enzymatic and non enzymatic antioxidants in the leaves of Cakile maritima is a plant succulent halophyte.
Heavy Metal Accummulation in Muscles and Total Bodies of Mullus barbatus, Trachurus trachurus and Engraulis encrasicolus Captured from the Coast of Sinop, Black Sea
(Zoological Soc Pakistan, 2016) Gundogdu, Ayse; Culha, Saniye Turk; Kocbas, Fatma; Culha, Mehmet
The levels of heavy metals viz., Cd, Cu, Fe, Ni, Pb, Zn and Al were determined by ICP-AES in the muscles and total bodies of Mullus barbatus (Linnaeus 1758), Trachurus trachurus (Linnaeus 1758), Engraulis encrasicolus (Linnaeus 1758) captured from the coast of Sinop. The order of the levels of the heavy metals in the total fish samples was Fe > Zn > Al > Pb > Cu > Ni > Cd, whereas in the muscles, the order was Zn > Fe > Cu > Al > Pb > Ni > Cd. The experiment results are discussed by comparison with literature values.
Investigation of Some Physiological and Biochemical Parameters in Pseudomonas syringae-Infected Tomato Plants
(Asian Journal Of Chemistry, 2010) Berber, I.; Onlu, H.; Ekin, S.; Battal, P.; Erez, M. E.
In the present study, the levels of manganese, magnesium, plant hormones (indole-3-acetic acid and abscisic acid), sugars (fructose and maltose), total chlorophyll and carotenoid contents in tomato plants following inoculation with Pseudomonas syringae pv. tomato were investigated. The trace element analysis showed that the levels of Mn significantly decreased in bacterium-infected tomato plants, comparing to the healthy plants. In contrary, the content of Mg in the bacterium-infected plants was higher than the uninfected plants. Manganese deficient in the bacterium-infected plants might be an important indicator against attempted bacterial infection. The results of phytohormone analysis showed that there may be an opposite relationship between the concentrations of endogenous indole-3-acetic acid and abscisic acid and the enhance disease resistance in bacterium-infected tomato plants. Therefore, it seems that indole-3-acetic acid, like abscisic acid, acts as a negative regulator of plant defense. Fructose concentrations increased in second, fourth, eight days after treatment with pathogen, but there was a decrease in tenth days. However, maltose levels decreased in all the periods after inoculation with the pathogen bacterium comparing to the control healthy plants. These results were also affirmed to the reduction in the total contents of chlorophyll and an increase of total carotenoids in the bacterium infected-plants. The investigation confirmed that there are complex relationships among trace element levels, endogenous plant hormone and sugar in the regulation of defense mechanisms against attacks by bacterial pathogens.
Meta-Analysis of Mathematics Interventions for Learners with Autism Spectrum Disorder
(Council Exceptional Children, 2024) Karal, Muhammed A.; Riccomini, Paul J.
Students with autism spectrum disorder (ASD) require effective academic interventions tailored to their distinctive learning characteristics. This is especially important in mathematics since approximately a quarter of learners with ASD have a mathematics learning disability. This meta-analysis examined the effectiveness of mathematics interventions for students with ASD by synthesizing and analyzing 33 studies that met inclusion criteria. The fi ndings indicate moderate to large Tau-U single-case effect sizes (ES = .91) for the interventions. Five distinct intervention approaches were identified: fi ed: multiple representations, video modeling, schema-based instruction, drill and practice, and multiple intervention components. Furthermore, these interventions were effective across various learner characteristics, mathematical performances, settings, and implementers. The implications for research and practice are discussed.
LIKELY EFFECTS OF GLOBAL CLIMATE CHANGE ON THE BLACK SEA BENTHIC ECOSYSTEM
(Scibulcom Ltd, 2010) Sezgin, M.; Bat, L.; Katagan, T.; Ates, A. S.
Occurrence and distribution of species in the Black sea are primarily determined by seawater temperature and salinity. The most recent predictions suggest that, by 2100, average air temperatures may be between 2 and 4 degrees C higher than at present and seawater temperatures may be as much as 2 degrees C higher than in 2000. The rise of the coastal zone seawater temperature may be higher than the open sea water average. It is expected that a warming of air and seawater temperatures will result in increased diversity of benthic marine life in the Black sea with adverse effects limited mainly to declines in abundance or loss of a small number of native species. Changes to a minority of biotopes might occur in the long-term. Depending on the temperature increase Mediterranisation of the Black sea fauna is in progress and occurs owing to immigration of new species. The aim of this article is discussing the global warming and the range of likely effects on marine benthic species. These effects may be related to changing water temperatures, changing water circulation or changing habitat. At present, to predict or detect the effects of climate change on marine benthic communities are quite difficult. But we can only provide educated guesses about potential changes and the consequences of those changes for the Black sea.
Sex Prediction of Hyoid Bone from Computed Tomography Images Using the DenseNet121 Deep Learning Model
(Soc Chilena Anatomia, 2024) Bakici, Rukiye Sumeyye; Cakmak, Muhammet; Oner, Zulal; Oner, Serkan
The study aims to demonstrate the success of deep learning methods in sex prediction using hyoid bone. The images of people aged 15-94 years who underwent neck Computed Tomography (CT) were retrospectively scanned in the study. The neck CT images of the individuals were cleaned using the RadiAnt DICOM Viewer (version 2023.1) program, leaving only the hyoid bone. A total of 7 images in the anterior, posterior, superior, inferior, right, left, and right-anterior-upward directions were obtained from a patient's cut hyoid bone image. 2170 images were obtained from 310 hyoid bones of males, and 1820 images from 260 hyoid bones of females. 3990 images were completed to 5000 images by data enrichment. The dataset was divided into 80 % for training, 10 % for testing, and another 10 % for validation. It was compared with deep learning models DenseNet121, ResNet152, and VGG19. An accuracy rate of 87 % was achieved in the ResNet152 model and 80.2 % in the VGG19 model. The highest rate among the classified models was 89 % in the DenseNet121 model. This model had a specificity of 0.87, a sensitivity of 0.90, an F1 score of 0.89 in women, a specificity of 0.90, a sensitivity of 0.87, and an F1 score of 0.88 in men. It was observed that sex could be predicted from the hyoid bone using deep learning methods DenseNet121, ResNet152, and VGG19. Thus, a method that had not been tried on this bone before was used. This study also brings us one step closer to strengthening and perfecting the use of technologies, which will reduce the subjectivity of the methods and support the expert in the decision-making process of sex prediction.
