Viticulture Biodiversity in Van Province
Viticulture preserved its significance from the past to the present that have been ruled in all civilization the region of Van. The presence of carbonized grape seeds in the remains of the Early Iron Age tombs and cities gives information about the history of grape cultivation in Van and its vicinities. However, many of the local varieties described by the elderly are now unfortunately not seen in large areas. Some of the genotypes are no longer encountered, while many genotypes are observed in a few vineyards with a few vines. The grape genetic resources except Erciş variety in the region are threatened with extinction. In spite of many ecological factors that restrict crop production in the region, vineyard has existed for thousands of years and urgent precautions have to be taken to protect this genetic heritage bearing grape landraces close to standard genotypes. The region has been investigated by many researchers for many years and the determined local varieties have been investigated in detail in terms of morphological and pomological characteristics, chemical contents and nutrients and defined in terms of molecular or ampelographic aspects in different studies. With this review, it is aimed to recover the knowledge of these genotypes in a single study in using scientific studies made up to this day in the region. So that it is aimed to lead the steps to be taken in the establishment of a gene pool composed of these local varieties which are under the risk of extinction is increasing day by day. The study also includes information on local adaptations of some standard grape cultivars that have been planted in previous years

Bu çalışma, Siirt Üniversitesi Fen Bilimleri Enstitüsü Bahçe Bitkileri Anabilim Dalı Koray Özrenk ve Nurhan Keskin'in danışmanlığında Servat Nas tarafından yazılan "Siirt yöresi elma (Malus domestica Borkh.) gen kaynakları" adlı yüksek lisans tezine dayanılarak hazırlanmıştır.This research was carried out on local apple varieties (Malus domestica Borkh.) that are grown in Şirvan, Pervari, Eruh districts and their villages in Siirt province. Fruit samples were taken between 2014-2015 from 21 different trees that are qualified, have high value in the market and preferred by local people. Phenological observations were recorded on selected trees and pomological properties were investigated on collected fruit samples. The budburst, beginning of flowering, flowering time, number of days from full bloom to harvest (FBD) and harvest date are recorded as phenological observations. According to the results, the budburst was between March 28th and May 3 rd , the date of first flowering was between April 2 nd and May 10th , the full of bloom was between April 9 th and May 17th ,the end of flowering was between April 14th and May 23rd , the harvest date was between 11th of August and14th of October, and the number of days from full bloom to harvest (FBD) was between 113 and 149 days. According to phenological observations, fruit weight was between 20,45 and 73,42 g, fruit sizes were between 32,73 and 60,10 mm, fruit diameters were between 36,27 and 60,32 mm, fruit stalk length was between 4,23 and 26,16 mm, fruit stalk thickness was between 1,96 and 2,61 mm, the amount of soluble solids of fruits was between %6,032 and 13,24, the amount of titratable acid was between %0,85 and 6,10, the juice pH was between 3,13 and 5,37. In addition to above parameters, fruit peel color, fruit flesh color, fruit grittiness and taste were also determined
Erzincan Yöresinde Yetişen Gilaburuların (Viburnum opulus L.) Bazı Fiziksel ve Kimyasal Özellikleri
This study was conducted in order to identify some physical and chemical characteristics of fruits and seeds in the genotypes of Gilaburu (Viburnum opulus L.) naturally grown in Erzincan region. In the study measurements were conducted regarding the weight, height, width, total soluble solid (TSS) content, pH, and titratable acidity (TA) content of the fruits as well as some physical characteristics of the seeds. The contents of organic acids (tartaric acid, malic acid, succinic acid, fumaric acid and acetic acid) and phenolic compounds (gallic acid, catechin, caffeic acid, syringic acid, p-coumaric acid, ferulic acid, o-coumaric acid, protocatechuic acid, vanillic acid, rutin and quercetin) in Gilaburu fruits were analyzed by HPLC. The findings of the study revealed that in the fruits, the content of tartaric acid (1.41 g kg-1-1.24 g kg-1) was higher than those of other organic acids while the content of catechin (284.96 mg kg-1- 352.04 mg kg-1) was higher than those of other phenolic compounds. In addition, mineral elements (K, Ca, Mg, Fe, Mn, Zn and Cu), sugar and vitamin C were determined in fruit samples.Bu çalışma Erzincan yöresinde doğal olarak yetişen Gilaburu (Viburnum opulus L.) genotiplerinin çekirdek ve meyvelerinin bazı fiziksel ve kimyasal özelliklerini belirlemek amacıyla yapılmıştır.Çalışmada meyvelerin ağırlığı, eni, boyu, pH, toplam kuru madde ve asit içeriklerinin yanı sıra çekirdeklerin bazı fiziksel özellikleri belirlenmiştir. Meyvelerin organik asit (tartarik asit, malik asit, sukkinik asit, fumarik asit and asetik asit) ve fenolik madde (gallik asit, kateşin, caffeic asit, syringik asit, p-kumarik asit, ferulik asit, o-kumarik asit, protokateşik asit, vanillik asit, rutin and kuersetin) içerikleri HPLC ile ölçülmüştür.Meyvelerin tartarik asit içeriği (1.41 g kg-1- 1.24 g kg-1) diğer organik asitlerden, kateşin içeriği ise (284.96 mg kg-1- 352.04 mg kg-1) diğer fenolik bileşiklerden daha yüksek bulunmuştur.Ayrıca meyvelerin mineral madde (K, Ca, Mg, Fe, Mn, Zn and Cu), şeker ve vitamin C içerikleri de belirlenmiştir
Classic Kaposi′s sarcoma with colonic involvement: A rare presentation with successful treatment with oral etoposide
Kaposi′s sarcoma (KS) is currently regarded as a low-grade vascular malignancy. KS is a multicentric and multisystem disease that involves the skin and less commonly visceral organs, such as the gastrointestinal system including colonic involvement. KS with colonic involvement in HIV-negative patients is a rare clinical manifestation. In this regard, we report an immunocompetent, HIV-negative elderly female patient with classic KS presenting with colonic involvement
Investigation of Some Physicochemical Traits and Changes After Storage of Fruits Belonging to 'Zivzik' Pomegranate Genotypes Grown in Siirt, Turkey
Pomegranate genotypes called 'Zivzik' are widely grown in Siirt, Turkey, and these genotypes have sweet, tart, and sour fruits. This study was carried out to determine the physicochemical traits of fruits belonging to 'Zivzik' pomegranate genotypes, as well as changes in fruit characteristics after storage. Sweet, tart, and sour 'Zivzik' pomegranate genotypes were harvested in Sirvan and Pervari districts of Siirt. The fruits were placed in modified atmosphere packages and kept at 6 degrees C and 90% relative humidity for 3 months. Some physicochemical traits were determined in both harvested and stored pomegranate fruits. Fruit weight (280.8 g), berry weight (0.41 g), fruit width (84.5 mm), and fruit length (8.57 mm) of the fruits of the sweet pomegranate genotype were found to be higher than in the other genotype fruits. However, the total soluble solids content (17.57%), titratable acid content (3.02 g/100 ml), total phenol content (163.43 mg GAE/100 ml), and antioxidant activity (49.95 mu mol TE/ml) of the fruits of the sour pomegranate genotype were higher than in fruits of other genotypes. There were differences between pomegranate genotypes in fruit peel color and berry size. After storage, there was a significant decrease in the titratable acid content of fruits in all genotypes, while their total soluble solids, total phenol content, and antioxidant activities increased. However, no significant change was found in fruit peel color in any genotype. Consequently, there were differences between the physicochemical traits of the fruits belonging to the sweet, tart, and sour 'Zivzik' pomegranate genotypes, but there were no significant changes in these traits after storage
