The Association of Nlr and Mpv With Treatment Responses, Disease Stages, and International Prognostic Index Scores in Diffuse Large B-Cell Lymphoma
(Yuzuncu Yil Universitesi Tip Fakultesi, 2019) Demircioğlu, S.; Doğan, A.; Ekinci, Ö.; Demir, C.
Diffuse Large B-Cell Lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma. International Prognostic Index (IPI) is the most commonly used scoring system predicting the prognosis. In this study, we aimed to investigate the association of Neutrophil/Lymphocyte Ratio (NLR) and Mean Platelet Volume (MPV) with IPI score, treatment responses, and disease stage. A total of 113 DLBCL patients who received R-CHOP treatment were recruited for this study. Demographic data, disease stages according to the Ann Arbor staging system, IPI scores, treatment methods, treatment responses, complete blood counts, and biochemical tests of the patients were retrospectively evaluated. Elevated NLR had statistically significant correlation with disease stage and IPI score (p=0.001 and p=0.006, respectively). However, the NLR had no statistically significant correlation with the interim-treatment and post-treatment responses (p=0.187, and p=0.96, respectively). MPV showed no significant relationship with disease stages (p=0.56), IPI scores (p=0.188), interim-treatment and post-treatment responses (p=0.122, and p=0.239). In conclusion, NLR was associated with IPI score and disease stage. This suggests that NLR, a cheap and easy investigation, may be used to obtain information about the prognosis. © 2019, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Comparison of Two Different Methods in Determination of Grapevine Leaf Area
(Centenary University, 2018) Doğan, A.; Uyak, C.; Gazioğlu Şensoy, R.İ.; Keskin, N.
Leaves are the basic organs that control many vital mechanisms such as photosynthesis, transpiration and respiration in plants; the species or variety is determined based on them in scientific studies; and the response of the plant to various stress conditions is measured on them. The determination of the surface area of leaves also sheds light on many studies. The present study aimed to compare two different methods for determining leaf area. With the first method used, the leaf area was determined from the pixel-area calculation using pixel values using the image processing program Photoshop CS6. The other method has been tried to determine the leaf area by using the weight-area relation. It was determined that the area found between the two methods varied between-12.93 cm 2 to 9.2 cm 2 on the leaves of 28 different grapevine varieties. By comparing these two methods, leaf area coefficient was determined for each variety. The regression coefficient was found as R 2 = 0.908 (p <0.01) between the area scanned on the computer and then determined by the Adobe Photoshop 6.0 program and the area by the weighted relational method. This statistically significant relationship between the two methods shows that the determination of leaf areas by using the weight-area relationship can be used in the condition where it is not possible to determine it by computer. © 2018, Centenary University.

Determination of Chlorophyll Amounts and Stoma Densities of Grape Cultivars Grown in Hizan (Bitlis) Conditions
(Centenary University, 2020) Doğan, A.; Uyak, C.; Akçay, A.; Keskin, N.; Şensoy, R.İ.G.; Çelik, F.; Özrenk, K.
In order to reveal effects of cultivar, methods used (nail polish and transparented leaf method), picking positions of the leaves (shade / sun) and sampling from different parts of the leaf surface (tip, middle, bottom) on stoma density and sizes and determine total chlorophyll, chlorophyll a, chlorophyll b, carotenoid amounts and SPAD values of the cultivars, this research was carried out on 28 local grape cultivars grown in Hizan province in 2017. In the study, it was determined that the effect of the cultivar, method used and picking position of the leaf on the stoma density was important, but the effect of sampling from different parts of the leaf surface on the stoma density was insignificant. Similarly, it was determined that the effect of the cultivar, method used and on the stoma sizes was important, but the effect of picking position of the leaf and sampling from different parts of the leaf surface on the stoma sizes was insignificant. It was concluded that the transparented leaf method should be preferred in making better stomatal observation in the hairy and rough grapevine leaves. In the study, it was determined that the effect of the cultivar on total chlorophyll, chlorophyll a, chlorophyll b and carotenoid amounts and SPAD values was important and there were important differences between cultivars in terms of these values. It was observed that the SPAD values of the leaves in the sun were higher than the leaves in the shade. © 2020, Centenary University. All rights reserved.
Determination of Pesticide Residue Amounts in Fresh Grapes, Raisins and Pickled Grape Leaves Sold in Van Province
(Centenary University, 2017) Gazioğlu Şensoy, R.I.; Ersayar, L.; Doğan, A.
Pesticides, although with many scientific studies have demonstrated that their damages to the environment and human health all over the world and in our country every day, are being more widespread plant protection products. The residues found in agricultural products bearing great importance in domestic and foreign trade can cause refusal of the products from border from time to time in the acceptance of our export products when they are detected in the range above the acceptable ratios. The present study tried to put the current situation and intended to determine in the amount of pesticide residues found in the samples of fresh grape, raisin, and brined vine leaves that are sold in the Van region and came from different regions, basically accepted as a grape producer in the country, such as Manisa, Kilis, Adıyaman-Besni, Siirt, Tokat, Balıkesir, Adana or Mersin, and even cross-border trade. Internationally recognized AOAC 2007.01 method was used in the pesticide analysis and 250 different pesticides were screened for each sample. In all 16 studied samples, 30 different pesticide residues were detected although the amounts and the resulting active substances of them were different, and it was also detected that some forbidden pesticides were used. Results were evaluated based on damage and allowed range given in Turkish Food Codex and the specified EU MRLs (Maximum Residue Limit) standards. 10 different pesticides were identified in the raisin, but there was no national or international standard range available, so the results could not be considered in the context of comparative damage threshold. A series observations and analysis was made in the brined vine leaves either home-made or the branded or unbranded commercial ones, and out of a commercial sample no pesticide residue was detected in the samples. Because there was no determined limit for the brined vine leaves, the comparisons were made on fresh vine standards, and 5 different pesticides were identified and found to be over the allowable range except one. It is thought that this study will be a reference for more specific studies that are planned to be implemented for some pesticide use in certain regions. Furthermore, this study is the first study conducted on the subject in the region. In the study the different grape products used and implementation and advice on what to do about pesticide residues were revealed. © 2017, Centenary University. All rights reserved.
Determination of Stoma Density and Distribution of Hazelnut (Corylus Avellana L.) Cultivars and Genotypes Grown in Different Ecologies
(Centenary University, 2020) Hurt, H.; Doğan, A.
In this study, the numbers and distribution of stomata in the leaves of eleven hazelnut cultivars and types grown in Trabzon and Hizan (Bitlis) district, which are two different ecologies, were examined. Stomata were observed hypostomatically only on the lower leaf surface The number of stoma in unit area (mm2) ranged from 90.00 (Turşink) to 111.60 (Himdi). The stoma length and stoma width of the cultivars were measured in the range of 23.31 (Herişte) –32.03 (Foşa) and 19.20 (Cavreş)-26.78 (Foşa). The highest values in terms of stoma length and stoma width were determined in Foşa hazelnut variety. Among the hazelnut cultivars and types, Himdi had the highest stoma index (19.43%), while Cavreş had the lowest stoma index (13.26%). The number of epidermis cells in the leaves of the cultivars and types ranged from 462.82 to 612.46 stoma mm-2. Negative correlations were found between the number of stoma and stoma length (-0.684-0.358) and stoma width (-0.706-0.856). These results showed the hazelnut varieties and genotypes have different stomata characteristics. It has been observed that the best method for determining the stomata structures in hazelnuts is the method of transparency. © 2020, Centenary University. All rights reserved.

Effect of the Application of Root Cutting After Germination on the Seedling Growth in the Walnut Seeds Taken From Van Lake Basin
(Centenary University, 2016) Yaviç, A.; Doğan, A.; Kazankaya, A.; Encü, T.
This research was cunducted in production greenhouses of Yuzuncu Yıl University Agriculture Faculty Horticultural Crops Department during 2014-2015. Walnuts taken from various areas of Van Lake basin were used as research material. In order to determine the effects of the application of root cutting methods on walnut seedlings after germination three different applications were used (cutting of radicle from 5 cm, cutting of radicle from 7 cm and control). One third of the walnuts which were ripped from the rooting area after germination have been planted without cutting the radicle and planted back to the germination area. The research revealed that the seedlings from control group performed well in shoot growth while the seedlings from 7 cm radicle cut group gave better results in the parameters about root development. The research also indicated that the area that welnut seeds were taken affected the seedling performences. © 2016, Centenary University. All rights reserved.
Effects of Different Crop-Load and Ethephon Treatments on Yield, Quality and Biochemical Parameters of Erciş Grape Cultivar
(Centenary University, 2020) Karateke, Ş.; Uyak, C.; Doğan, A.
This study was conducted to investigate the effects of different crop-load and ethephon treatments on yield, quality and biochemical characteristics of Erciş grape cultivar in 2017. Experimental vines were grown on their own roots and trained in gobble style. Following the fruit-set, cluster thinning was performed as to have two different fruit loads (20 and 30 cluster/vine). Ethephon (CEPA 2-Chloroethylphosphonic acid) was sprayed externally only to the clusters in 4 different doses (0-100-500-1000 ppm) twice 7th and 14th days after veraison. Crop loads and ethephon treatments had significant effects on vine yield, cluster width, 100-berry weight, berry length and width, L* and b* values, syringic and p-coumaric acid contents of Erciş grapes. In both crop loads, as compared to the control, ethephon doses generally decreased vine yield, cluster weight, length and width, berry length, width and 100-berry weight, tartaric and malic acid contents, pH and total acidity and increased soluble solid contents. © 2020, Centenary University.

Effects of Indole-Butyric Acid Doses, Different Rooting Media and Cutting Thicknesses on Rooting Ratios and Root Qualities of 41b, 5 Bb and 420a American Grapevine Rootstocks
(Nobel Science and Research Center, 2016) Doğan, A.; Uyak, C.; Kazankaya, A.
The present study was conducted to investigate the effects of different rooting media [perlite, perlite+sand (1:1), perlite+sand+soil (1:1:1)], different indole butyric acid (IBA) doses (control, 1000, 2000, 3000 and 4000 ppm) and different cutting thicknesses [thin (4-7 mm), medium (8-10 mm) and thick (10-12 mm)] on rooting and root qualities of 41B, 5BB and 420A American grapevine rootstocks adapted to Van region of Turkey. Within the scope of the study, rooting ratios (%), number of roots, root lengths (cm) and root weights (g) were determined. The differences in rooting ratios, number of roots, root lengths and root weights of rootstocks were found to be significant (P < 0.05). Rooting ratios and root quality parameters of cuttings significantly varied with rootstocks, IBA doses, rooting media and cutting thicknesses. With regard to rooting ratios, number of roots and root weights, 5BB rootstock yielded better outcomes than 420A and 41B rootstocks. Compared to control treatment, IBA treatments increased rooting ratio, number of roots, root length and root weight of all three rootstocks. Among the rooting media, the best outcomes for rooting ratio, root length and root weight were obtained from perlite medium and the best results for number of roots were obtained from perlite+sand+soil medium. With regard to cutting thickness, thick cuttings were prominent and they were closely followed by medium ones.
Oxidative Damage in Some Tissues of Van Fish (Alburnus Tarichi Güldenstädt, 1814) Having Abnormal Ovary
(Centenary University, 2017) Özok, N.; Oğuz, A.R.; Doğan, A.; Ergöz, B.
Van Lake is the largest soda lake of Turkey and there is only one fish species (Van Fish, Alburnus tarichi Güldenstädt, 1814) that can survive under the extreme conditions of the lake. There are several researches carried out on the issue of lake contamination recently. Gonad abnormalities observed among these fish are one of the most important issues. In the present study, the malondialdehyde (MDA) and reduced glutathione (GSH), and the antioxidant enzyme levels such as superoxide dismutase (SOD) and glutathione peroxidase (GSH - Px) are compared in gills, livers, and gonads of the Van Fish (the ovary abnormality of which are determined in Van Lake) and the normal fish. Compared to the normal fish, the MDA levels of the abnormal fish show a considerable amount of increase in all of the tissues (P<0.05). There is a significant decrease in the SOD activity in the gill and ovary tissue and in the GSH - Px activity in the livers of the abnormal individuals compared to the normal individuals (P<0.05). As for the GSH levels, there is no difference found when the normal and abnormal tissues are compared. Consequently, when the fish with ovary abnormalities which are thought to be exposed to contaminators in a certain time period is compared to the normal fish, it can be said that their antioxidant defense systems are affected. © 2017, Centenary University.

The Presence of Paroxysmal Nocturnal Hemoglobinuria in Patients With Idiopathic Chronic Renal Failure
(Yuzuncu Yil Universitesi Tip Fakultesi, 2017) Ekinci, Ö.; Doğan, A.; Demir, C.
Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal stem cell disease. Chronic renal f ailure (CRF) is defined as progressive deterioration in the regulation of fluid and electrolyte balance of the affected kidney due to a decrease in glomerular filtration rate resulting from various diseases. We also investigated the presence of PNH in foll ow-up patients diagnosed with end-stage renal failure (ESRD) of unknown etiology in this study. This study was carried out at the Yuzuncu Yil University in Van, Turkey. Sixteen patients with end-stage renal failure who had unknown etiology from a total of 143 patients were included in the study. The patients’ age, gender, hemogram, biochemical parameters, and percentage of PNH clone were exami ned. PNH clone was analyzed by the Fluorescein Aerolysin method. Of the patients, 10 (62%) were female, 6 (38%) were male. Hemodialysis was performed in 15 patients (94%) as renal replacement therapy. Fourteen of the patients (88%) had anemia. LDH was elev ated in 6 patients (38%), and those with high LDH also suffered from anemia. PNH clone was negative for all patients as determined by FLAER analysis. A survey of the literature did not result in any study on the presence of paroxysmal nocturnal hemoglobinu ria in idiopathic chronic renal failure. This is the first such study with this focus. Based on review of the cases described in the literature, PNH should be considered in the differential diagnosis of renal failure cases which are unexplained and especia lly those accompanied by hemolysis findings. © 2017, Yuzuncu Yil Universitesi Tip Fakultesi.

(Yuzuncu Yil Universitesi Tip Fakultesi, 2015) Ünsal, S.Ş.; Ceylan, M.F.; Güner, S.; Gökalp, M.A.; Türktaş, U.; Doğan, A.; Gözen, A.
We aimed to evaluate the clinical and radiological results of open reduction (OR) and Salter innominate osteotomy (SIO) for patients with developmental dysplasia of the hip (DDH). In this study, the results of 45 instances of OR and SIO treatment on 36 DDH patients between 2004 and 2012 were evaluated retrospectively. 28 (77.77%) of the patients were female and 8 (22:33%) of them were male. The mean age was 28.8 (18-55) and the mean follow-up period was 41.8 months (6-101). A recovery percentage was calculated by measuring the acetabular index on plain radiographs recorded before surgery, immediately after surgery, and final checkup. During patients’ final checkup, the clinical evaluation was performed according to a modified version of McKay’s criteria and the evaluation of the range of the joint motion was carried out according to the Trevor-Johns-Fixen scoring system. The acetabular index values recorded from patients’ hips had an average of 39.9 (35-47) degrees before the operation, but had a mean of 30.5 (20-35) degrees after the operation and an average of 18.5 (10-30) degrees during the final checkup. Clinically, excellent results were obtained in 22 hips (49%), good results were obtained in 17 hips (38%), and satisfactory results were obtained in 4 hips. Two of the patients could not be evaluated since they could not be mobilized due to cerebral palsy. Re-dislocation emerged in 3 hips (6.6%), deep infection emerged in 1 hip (2.2%), and a supracondylar femur fracture emerged for 1 patient (2.2%). OR and Salter’s innominate osteotomy is a highly effective surgical technique in the treatment of DDH cases that have lasted more than 18 months. © 2015, Yuzuncu Yil Universitesi Tip Fakultesi.

(Springer-Verlag France, 2014) Gokalp, M.A.; Guner, S.; Ceylan, M.F.; Doğan, A.; Sebik, A.
Introduction: The aim of this study was to evaluate the outcomes of creation of a gutter and muscle flap transposition method for the treatment of long-bone chronic osteomyelitis. Patients and methods: A total of thirty chronic osteomyelitis patients (thirty-one extremities), who had undergone the gutter creation and muscle flap transposition procedure between 2005 and 2009, were included in the study (19 male, 11 female; mean age 24.4 years; age range 2-75 years). Osteomyelitis of the long bones involved the femur in 13 patients, the tibia in 13, the humerus in 2, the fibula in 2 and the ulna in 1 patients, respectively. All the patients received post-operative antibiotic therapy of at least 6 weeks. The mean follow-up period was 28.7 months (6-53 months). At the end of this follow-up period, the patients were evaluated using clinical, laboratory and screening methods. Results: Complete pain relief, disappearance of toxic symptoms, improvement in radiological findings, fistula closure and return of the blood parameters to normal ranges were accepted as successful treatment when all the afore-mentioned had been fulfilled. According to these criteria, 29 of the 30 patients had been cured. Discussion: The gutter creation and muscle flap transposition method in the treatment of long-bone chronic osteomyelitis may be a successful mode of therapy when performed correctly and supported by long-term antibiotherapy. © 2013 Springer-Verlag.
The Role of Paroxysmal Nocturnal Hemoglobinuria in Idiopathic Habitual Abortion
(Yuzuncu Yil Universitesi Tip Fakultesi, 2017) Dirik, Y.; Ekinci, Ö.; Kara, O.; Dirik, D.; Doğan, A.; Demir, C.
Paroxysmal nocturnal hemoglobinuria (PNH) which is an acquired clonal hematopoietic stem cell disease, usually presents with intravascular hemolysis, thrombosis and bone marrow failure. Hereditary and acquired thrombophilia are known to play significant role in the etiology of patients with habitual abortion (HA). PNH, which is a cause of acquired thrombophilia, may have a role in the etiology of HA. In the present study, we investigated the presence of PNH clone among the patients with a history of HA. 150 patients were enrolled in the study group, diagnosed with habitual abortus of unknown etiology and 150 healthy women with no history of habitual abortus as a control group. The age range for both groups was 18–55 years. The PNH clone was screened by the FLAER (fluorescein-labeled proaerolysin) method. The PNH clone was positive in five (3.3%) patients in the study group. Four of the PNH clone positive patie nts were found to have a very low clone positivity level (0.05%, 0.24%, 0.12%, 0.21%), while one had a high level (30%). PNH clone positivity results in the study group indicate that PNH should be investigated in cases of idiopathic HA, as one patient required treatment. © 2017, Yuzuncu Yil Universitesi Tip Fakultesi.
