Publication The influence of environmental and atmospheric variables on allergenic pollen(Bilimsel Tıp Yayınevi, 2016-12-01) Bıcakçı, Adem; Tosunoğlu, Aycan; BIÇAKÇI, ADEM; TOSUNOĞLU, AYCAN; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü; 0000-0002-6333-3123; 0000-0003-2303-672X; O-1244-2018; GDS-1748-2022Atmospheric pollen grains belong to mostly wind pollinated plants, which may cause respiratory allergies, and their concentrations in the air is largely influenced by climatic parameters. In general, the days with sun, high temperature and moderate wind, and without rain are the periods that have shown maximum pollen release. In the studies of the last century it has been shown that global warming and increasing CO2 concentrations in the world affected the starting and ending dates of pollination periods for some plants and their pollen concentrations in the atmosphere. The other important effect of atmospheric changes on pollen grains is seen in long-range transport. Additionally, the North Atlantic Oscillation (NAO) has an influence on long-range transport, especially affecting the plants in the early spring and leading to early or late onset of pollination.Publication Yellow rain on the ridge of Uludag mountain, nw-Turkey(Parlar Scientific Publications (P S P), 2019-01-01) Tosunoğlu, Ayçan; Bıçakçı, Adem; TOSUNOĞLU, AYCAN; BIÇAKÇI, ADEM; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Bioloji Bölümü; 0000-0002-6333-3123; O-1244-2018; GGP-2094-2022In this study, atmospheric pollen grains investigated with the gravimetric method in years 2014 and 2015. Annually 12158 pollen grains, belonging to 52 plant taxa identified and pollen grains of woody taxa consist of 93.30% of the annual pollen index, which found concordant and evaluated as a reflection of the dominated flora and vegetation of the area. Pollen types belonging to Pinus, Quercus, Cupressaceae/Taxaceae, Cedrus, Poaceae, Plantago and Abies were classified as dominant pollen types for the region and the total amount for them were 94.37% of annual pollen index. Of these, 59.87% of dominated pollen types belonging to Pinaceae family members and can be shown as a reason for high yellow rain in the study area. It was noted that Gymnosperm trees such as Pinus, Cupressaceae/ Taxaceae, Cedrus and also Quercus, which produce excessive amounts of pollen were particularly affected by rainfall and humidity in their pollination period. The month, in which pollen was the highest in the year, was recorded as April in both sampling years. April-May term found as an overlap of pollination periods and can be thought as a risky period for sensitive individuals for the region.Publication Airborne pollen grains of Gemlik (Bursa)(Bilimsel Tıp Yayınevi, 2011-01-01) Saatcioğlu, Gülşah; Tosunoğlu, Aycan; Malyer, Hulusi; Bıçakcı, Adem; Saatcioğlu, Gülşah; TOSUNOĞLU, AYCAN; MALYER, HULUSİ; BIÇAKÇI, ADEM; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; 0000-0002-6333-3123; 0000-0001-5124-7239; O-1244-2018; HLH-0776-2023; GGP-2094-2022; DDS-8738-2022Objective: Pollen calendars, which exposes by determinig airborne pollen, help the allergologists and the people that sensitive to allergenic pollen. The goal of this study to identify the airborne pollen grains to establish the pollen calendar of Gemlik (Bursa) in the year 2008.Materials and Methods: Airborne pollen grains in Gemlik (Bursa) were collected between 1st January and 31st December 2008 by using Durham sampler. Weekly pollen grains per cm2 were calculated.Results: During the period 6957 pollen grains/cm(2) belonging to 43 taxa (excluding unidentified pollen grains) were recorded. Eleven plant taxa take a place, which encountered up to 1% of the total and it can be reported that pollen season durations and total percentages for the dominaing pollen grains in Gemlik were; 5-32nd week for Pinus spp. (22.14%), 19-37th week for Olea europaea L. (18.19%), 9-43rd week for Gramineae (10.62%), 1224th week for Platanus spp. (10.58%), 4-27th week for Cupressaceae/Taxaceae (10.19%), 13-23rd week for Fagus spp. (6.09%), 9-21st week for Quercus spp. (5.33%), 5-19th week for Fraxinus spp. (2.41%), 423rd week for Betula spp. (1.81%), 27-44th week for Xanthium spp. (1.53%) and 14-22nd week for Jug-lans spp. (1.35%). 40.46% of total pollen grains were recorded during the month of april with a prevalence of arboreal pollen grains.Conclusion: This preliminary study performed to determine pollen calendar for Gemlik region (Bursa) may be useful for allergologists to establish an exact diagnosis of the people that has pollen allergy.Publication Pollen diversity in the atmosphere of Karacabey (Bursa), Turkey(Turkish Natl Soc Allergy and Clinical Immunology, 2019-01-01) Bekil, Semih; Tosunoğlu, Aycan; Bıçakcı, Adem; Bekil, Semih; TOSUNOĞLU, AYCAN; BIÇAKÇI, ADEM; Bursa Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; 0000-0002-6333-3123; 0000-0002-8783-1389; 0000-0003-2303-672X; O-1244-2018; CEY-2487-2022; GGP-2094-2022Pollen grains are known as important bio-allergens for sensitive individuals because of their presence in the air we breathe. Therefore, it is important to know the pollen load, major pollen types and sesonal variations of them for each populated region. The aim of this study was to determine the pollen types, densities and the pollen seasons of main pollen producers in Karacabey area. Pollen quantities and diversity studies were carried out by the gravimetric method in Karacabey (Bursa) atmosphere for two years, between 1 January 2015 and 31 December 2016. During sampling, the slides were changed weekly and examined by light microscopy. Annually 14226 pollen grains (15281 in 2015 and 13171 in 2016) belonging to 59 plant taxa (32 woody and 27 herbaceous taxa) were identified and pollen grains of woody taxa represented 72.63% (77.00% in 2015 and 68.27% in 2016) and herbaceous taxa represented 26.69% (22.30% in 2015 and 31.09% in 2016) of the annual pollen index (API) which was concordant and evaluated as a reflection of the dominant flora and maquis vegetation of the area. Types of pollen identified belonged to Cupressaceae/Taxaceae, Pinus, Poaceae, Quercus, Platanus, Ambrosia, Olea, Plantago, Amaranthaceae, Salix, and Fraxinus which were classified as dominant pollen types for the region and the the total amount for them was 88.21% of the annual pollen index. In this regard, April-May and August-September can be thought of as a risky period for sensitive individuals living in or visiting the region. One of the most exciting findings of this study was the high dominance of highly allergenic Ambrosia pollen in the atmosphere.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 Airborne pollen grains of Turkey(Bilimsel Tip Yayinevi, 2009-01-01) Bıçakçı, Adem; BIÇAKÇI, ADEM; CANITEZ, YAKUP; Altunoğlu, Mustafa Kemal; Bilişik, Aycan; Çelenk, Sevcan; ÇELENK, SEVCAN; SAPAN, NİHAT; Sapan, Nihat; Malyer, Hulusi; MALYER, HULUSİ; 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; O-1244-2018; K-2981-2012In this evaluation, the results of aeropalynological studies carried out for 49 regions of Turkey have been assessed. The most common and greatest amounts of pollens in the atmosphere of Turkey were Cupressaceae, Pinus and Gramineae. The highest amount for pollen grains was recorded between March and June.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 Airborne Populus (poplar) and Salix (willow) pollen grains belonging to Salicaceae family in Turkey(Bilimsel Tıp Yayınevi, 2014-01-01) Bıçakcı, Adem; Tosunoğlu, Aycan; Altunoğlu, Mustafa Kemal; Saatcıoğlu, Gülşah; BIÇAKÇI, ADEM; TOSUNOĞLU, AYCAN; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; O-1244-2018; GGP-2094-2022Introduction: White hairy seeds (cottony tufts) which are spreading to the air from poplar and willow trees, are mostly supposed to be a pollen grain by many people and there is a misconception that consisting allergenic symptoms thought to be due to these seeds. Whereas the air dispersed fluffy structures occur on female poplar and willow trees that are not producing any pollen. In this term, when the seeds of poplar and willow trees matured and dispersed, there are not any pollen grains of these plants in the atmosphere. The pollen grains belonging to both taxa have especially seen in the spring term and they cause sensitization in varying proportions on many individuals suffering from seasonal rhinitis and/or asthma.Materials and Methods: In this study, monthly changes and frequencies of pollen grains belonging to Populus (poplar) and Salix (willow) genera, belonging to Salicaceae family, from 62 airborne pollen studies carried out in Turkey, which prepared both volumetric method by using Lanzoni/Burkard samplers and gravimetric method by using Durham samplers, and studies on pollen sensitivities for both taxa are evaluated. Also daily distributions of poplar and willow pollen grains were investigated in Bursa city in the year 2013.Results: In many regions that airborne studies performed, pollen grains of poplar tree found in the air especially in march-april term and the pollen grains of willow tree in april-may term. In Bursa city, main pollen season of poplar tree found between 27 February-26 April and for willow tree it was between 25 March-28 April.Conclusion: In many regions that atmospheric studies undertaken both of poplar and willow tree pollen grains founded in low levels. Also pollen amounts of both taxa determined in the air of Bursa were low as in the other regions.Publication Botanical characterisation of natural honey samples from a high altitudinal region, Gumushane, East-Turkiye(Taylor & Francis As, 2022-12-20) Tosunoglu, Hakan; TOSUNOĞLU, AYCAN; Ergün, Nilgün; Bicakci, Adem; BIÇAKÇI, ADEM; Bursa Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Biyoloji Bölümü.The aim of our study is to determine important honey resources and botanical characterisation of honey in a high-altitude region of Turkiye. Natural honey samples were collected from all possible locations in 2017. The melissopalynological analysis identified 14 unifloral honey samples, and many plants were also determined as important sources for multifloral honey. Principal component analysis separated honey samples from low-altitude regions while high-altitude regions form a tight cluster. Pollen diversity was found to be lower in honeys at low altitudes and higher pollen diversity was found in honeys at high altitudes. Altitude plays an important role in the pollen content of the honey, with Cornus mas, Asteraceae, and Hypericum being indicator pollen types above 1500 m; Castanea sativa and Myosotis pollen were found predominant or secondary under 1100 m altitude. This has allowed the altitude preferences of some plants, which are important for beekeeping, to be associated with the location of the apiaries and, therefore, the composition of the honey.Publication Analysis of airborne pollen fall in Tekirdag, Turkey(Bilimsel Tip Yayinevi, 2010-01-01) Aybeke, Mehmet; Erkan, Perihan; ERKAN ALKAN, PERİHAN; Bıçakcı, Adem; BIÇAKÇI, ADEM; Bursa Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Biyoloji Anabilim Dalı.; 0000-0002-8837-3375; 0000-0002-6333-3123; 0000-0001-9512-5313; O-1244-2018; AAK-4004-2021Objective: Airborne pollen grains are important aeroallergens. When released in sufficient amounts, allergenic pollen may evoke allergic responses in the sensitive patients, leading to allergic rhinitis and asthma. The aim of this study was to determine pollen grains and changes in pollen fall per cm(2) weekly, monthly and annually in the atmosphere of Tekirdag.Materials and Methods: In this study, pollen grains were collected from the atmosphere of Tekirdag in 2002 and 2003 using a Durham sampler.Results: During these two years, a total of 7183 pollen grains were recorded. A total of 3462 pollen grains per cm(2) were recorded in 2002 and a total of 3721 pollen grains per cm(2) in 2003. Pollen fall in the years 2002-2003 comprised grains belonging to 45 taxa. Of these taxa, 25 belonged to arboreal and 20 taxa non-arboreal plants. Total pollen grains consisted of 64.08% grains from arboreal plants, 35.89% grains from non-arboreal plants and 0.03% unidentified pollen grains. In the region investigated, Cupressaceae/Taxaceae (Cypress/Taxus family), Pinus spp. (Pine), Gramineae (Grass), Chenopodiaceae/Amaranthaceae (Chenopod/Amaranth family), Quercus spp. (Oak), Xanthium spp. (Cockleburs), Juglans spp. (Wallnut), Platanus spp. (Plane tree), Aesculus spp. (Horse chestnut), Fraxinus spp. (Ash), Oleaceae (Olive family), Salix spp. (Willow), Plantago spp. (Plantain), Rumex spp. (Sorrel), Artemisia spp. (Mugwort) and Betula spp. (Birch) released the greatest amounts of pollen. The months of maximum pollen fall was from April to June.Conclusion: The pollen calendar for Tekirdag region presented in this paper may be useful for showing the timing of pollen seasons to visitors to the city, and may be useful for allergologists to establish an exact diagnosis.
