Publication Temporal variations in fungal spores in Mardin city atmosphere, upper Mesopotamia, SE-Turkey(Taylor & Francis, 2021-07-20) Sevindik, Mustafa; Akgül, Hasan; Tosunoğlu, Aycan; TOSUNOĞLU, AYCAN; GGP-2094-2022The present study aimed to determine the fungal spores and their concentrations in the atmosphere of Mardin (southeast Turkey) in 2014 and 2015 using the volumetric method. A total of 43 taxa, hyphal fragments, and single septate ascospores were identified by light microscopy. It was determined that the dominant fungal spores included Cladosporium (51.5%), Ustilaginales species spores (13.9%), Alternaria (6.9%), Pucciniales species spores (1.6%), Agrocybe (1.2%), Pleospora (1.1%) and hyphal fragments (15.5%). The highest atmospheric spore concentrations were observed in May and the lowest levels were determined in February in both years. Dry air spores constituted a significant ratio of the total count (73.9%) in the atmosphere of Mardin. There were significant positive correlations between atmospheric concentrations of Alternaria, Cladosporium, Ustilaginales, and Pucciniales spores and temperatures. There were significant negative correlations between airborne fungal spore concentrations and daily mean humidity. There was a significant negative correlation between Agrocybe spore concentrations and daily mean temperature and a significant positive correlation between the same and humidity and precipitation. No significant correlation was determined between the meteorological variables and Pleospora and Aspergillus/Penicillium spore concentrations.Publication Aristolochia altanii (Aristolochiaceae), a new species from Turkey(TÜBİTAK, 2015-01-01) İlcim, Ahmet; Behçet, Lütfi; Tosunoğlu, Aycan; TOSUNOĞLU, AYCAN; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; 0000-0003-2303-672X; GDS-1748-2022Aristolochia altanii Ilcim & Behcet sp. nov. is described from Turkey and illustrated. The specimens were collected from Kahramanmaras in South Anatolia. The new species is closely related to A. guichardii and A. brevilabris. However, this species differs in some important characteristics, such as the length of the pedicel and the perianth, the indument of the perianth limb, and the micromorphology of the pollen and the seeds. The diagnostic characters are discussed and taxonomic comments are presented.Publication Allergenic Platanus (plane tree) pollen concentrations in Turkey(Bilimsel Tip Yayinevi, 2015-01-01) Bıçakçı, Adem; Saatçıoğlu, Gülşah; TOSUNOĞLU, AYCAN; BIÇAKÇI, ADEM; Bursa Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Biyoloji Bölümü.; 0000-0002-6333-3123; O-1244-2018Objective: Plane tree pollen grains has an important place among aeroallergens that present in the air and cause allergy by entering the body via respiratory track.Materials and Methods: In this study, monthly variation and annual proportions of Platanus pollen investigated for 72 atmospheric pollen studies in Turkey, which carried out by using Lanzoni/Burkard sampler with volumetric method or by using Durham sampler with gravimetric method. Furthermore, researches evaluated about Platanus pollen sensitivities, performed in Europe and our country.Results: According to the atmospheric pollen studies, plane tree pollen grains have been detected in a very short period and intensively in the air. In some regions, Platanus pollen found in very highlevels and placed in most dominated five taxa among the total. In Bursa city, main pollen season of plane tree pollen grains continued for 62 days in the year 2013.Conclusion: Due to carrying out widespread planting of Platanus for decorative purposes especially in parks, gardens and along the streets in recent years and producing large amounts of pollen in spring period especially in April and May; it should be considered that symptoms can occur in people who are sensitive to plane tree pollen. In addition it must not forgotten that, vegetable originated food allergy (oral allergy syndrome) can be accompanied with Platanus pollen allergy on these individuals.Publication Allergenic Cupressaceae (cypress family) pollen concentrations in Turkey(Bilimsel Tip Yayinevi, 2010-01-01) Bıçakçı, Adem; BIÇAKÇI, ADEM; Tosunoğlu, Aycan; TOSUNOĞLU, AYCAN; Altunoğlu, Mustafa Kemal; Çelenk, Sevcan; ÇELENK, SEVCAN; Erkan, Perihan; ERKAN ALKAN, PERİHAN; Canıtez, Yakup; CANITEZ, YAKUP; Malyer, Hulusi; MALYER, HULUSİ; Sapan, Nihat; SAPAN, NİHAT; Bursa Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Biyoloji Bölümü.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Çocuk Sağlığı ve Hastalıkları Anabilim Dalı.; 0000-0002-6333-3123; 0000-0003-4925-8902; 0000-0002-8837-3375; K-2981-2012; AAK-4004-2021; O-1244-2018Cupressus and Juniperus airborne pollen grains, belonging to the Cupressaceae family and causing respiratory system allergy by inhalation, have an important place among aeroallergens. In this study, airborne pollen studies were carried out in Turkey, and the monthly changes in Cupressaceae pollens rates in 57 regions were evaluated. Results of the studies showed that the highest numbers of Cupressaceae pollen grains were recorded between march and may.Publication Allergenic airborne olea (olive) and fraxinus (ash) pollen concentrations belonging to the oleaceae family in Turkey(Bilimsel Tip Yayinevi, 2009-01-01) Bıçakcı, Adem; TOSUNOĞLU, AYCAN; BIÇAKÇI, ADEM; Altunoğlu, Mustafa Kemal; SAPAN, NİHAT; ÇELENK, SEVCAN; Çelenk, Sevcan; Canıtez, Yakup; CANITEZ, YAKUP; Canıtez, Yakup; Malyer, Hulusi; MALYER, HULUSİ; Sapan, Nihat; TOSUNOĞLU, AYCAN; Bursa Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Biyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Pediatri Anabilim Dalı.; 0000-0002-6333-3123; 0000-0003-4925-8902; O-1244-2018; K-2981-2012One of the most important allergens causing allergic diseases of the respiratory system is airborne tree, grass and weed pollen grains. Oleaceae family members are very important in tree pollen grains. In this study, airborne pollen studies were carried out in Turkey, and the monthly changes in Olea and Fraxinus pollens rates for 55 regions were evaluated. In the studies carried out, the highest Fraxinus pollen grains were recorded in spring, and Olea pollen grains were recorded in late spring and early summer. According to atmospheric pollen studies, although Fraxinus pollen grains were found in more regions than Olea, more Olea pollen grains were recorded than of Fraxinus.
