Publication Investigation of infectious droplet dispersion in a hospital examination room cooled by split-type air conditioner(Springer, 2024-05-08) Yüce, Bahadir Erman; Kalay, Onur Can; Karpat, Fatih; Alemdar, Adem; Temel, Şehime Gülsün; Dilektaşlı, Aslı Görek; Başkan, Emel Bülbül; Özakın, Cüneyt; Coşkun, Burhan; YÜCE, BAHADIR ERMAN; Kalay, Onur Can; KARPAT, FATİH; ALEMDAR, ADEM; TEMEL, ŞEHİME GÜLSÜN; GÖREK DİLEKTAŞLI, ASLI; BÜLBÜL BAŞKAN, EMEL; ÖZAKIN, CÜNEYT; COŞKUN, BURHAN; Bursa Uludağ Üniversitesi/Yenişehir İbrahim Orhan Meslek Yüksekokulu/İklimlendirme ve Soğutma Teknolojisi Bölümü.; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Makine Mühendisliği Bölümü.; Bursa Uludağ Üniversitesi/Sağlık Bilimleri Enstitüsü.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Genetik Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Histoloji ve Embriyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Hastalıkları Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Dermatoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Enfeksiyon Hastalıkları ve Mikrobiyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Üroloji Anabilim Dalı.The novel coronavirus (SARS-CoV-2) outbreak has spread worldwide, and the World Health Organization (WHO) declared a global pandemic in March 2020. The transmission mechanism of SARS-CoV-2 in indoor environments has begun to be investigated in all aspects. In this regard, many numerical studies on social distancing and the protection of surgical masks against infection risk have neglected the evaporation of the particles. Meanwhile, a 1.83 m (6 feet) social distancing rule has been recommended to reduce the infection risk. However, it should be noted that most of the studies were conducted in static air conditions. Air movement in indoor environments is chaotic, and it is not easy to track all droplets in a ventilated room experimentally. Computational Fluid Dynamics (CFD) enables the tracking of all particles in a ventilated environment. This study numerically investigated the airborne transmission of infectious droplets in a hospital examination room cooled by a split-type air conditioner with the CFD method. Different inlet velocities (1, 2, 3 m/s) were considered and investigated separately. Besides, the hospital examination room is a model of one of the Bursa Uludag University Hospital examination rooms. The patient, doctor, and some furniture are modeled in the room. Particle diameters considered ranged from 2 to 2000 mu m. The evaporation of the droplets is not neglected, and the predictions of particle tracks are shown. As a result, locations with a high infection risk were identified, and the findings that could guide the design/redesign of the hospital examination rooms were evaluated.Publication Contribution of genotypes in Prothrombin and Factor V Leiden to COVID-19 and disease severity in patients at high risk for hereditary thrombophilia(Wiley, 2023-02-01) Kiraz, Aslıhan; Sezer, Özlem; Alemdar, Adem; Canbek, Sezin; Duman, Nilgün; Bişgin, Atıl; Cora, Tülin; Ruhi, Hatice Ilgın; Ergören, Mahmut Çerkez; Geçkinli, Bilgen Bilge; Sağ, Şebnem Özemri; Gözden, Hilmi Erdem; Öz, Özlem; Altıntaş, Zühal Mert; Yalçıntepe, Sinem; Keskin, Adem; Tak, Ayşegüel Yabacı; Paskal, Şeyma Aktaş; Yürekli, Uğur Fahri; Demirtaş, Mercan; Evren, Emine Ünal; Hanta, Abdullah; Başdemirci, Müeşerref; Süer, Kaya; Balta, Burhan; Kocak, Nadir; Karabulut, Halil Guerhan; Çobanoğulları, Havva; Ateş, Esra Arslan; Bozdoğan, Sevcan Tuğ; Eker, Damla; Ekinci, Sadiye; Nergiz, Sueleyman; Tuncali, Timur; Yagbasan, Serap; Alavanda, Ceren; Kutlay, Nuket Yurur; Evren, Hakan; Erdogan, Murat; Altiner, Sule; Sanlidag, Tamer; Gonen, Gizem Akinci; Vicdan, Arzu; Eras, Nazan; Eker, Hatice Kocak; Balasar, Özgür; Tuncel, Gulten; Dündar, Munis; Gürkan, Hakan; ALEMDAR, ADEM; ÖZEMRİ SAĞ, ŞEBNEM; TEMEL, ŞEHİME GÜLSÜN; Gozden, Hilmi Erdem; Bursa Uludağ Üniversitesi/Sağlık Bilimleri Enstitüsü/Translasyonel Tıp Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Genetik Anabilim Dalı.; ELA-3536-2022; IYV-1877-2023; JMQ-2372-2023; IRT-7350-2023Thrombotic and microangiopathic effects have been reported in COVID-19 patients. This study examined the contribution of the hereditary thrombophilia factors Prothrombin (FII) and Factor V Leiden (FVL) genotypes to the severity of COVID-19 disease and the development of thrombosis. This study investigated FII and FVL alleles in a cohort of 9508 patients (2606 male and 6902 female) with thrombophilia. It was observed that 930 of these patients had been infected by SARS-CoV-2 causing COVID-19. The demographic characteristics of the patients and their COVID-19 medical history were recorded. Detailed clinical manifestations were analyzed in a group of cases (n = 4092). This subgroup was age and gender-matched. FII and FVL frequency data of healthy populations without thrombophilia risk were obtained from Bursa Uludag University Medical Genetic Department's Exome Databank. The ratio of males (31.08%; 27.01%) and the mean age (36.85 & PLUSMN; 15.20; 33.89 & PLUSMN; 14.14) were higher among COVID-19 patients compared to non-COVID-19 patients. The prevalence of FVL and computerized tomography (CT) positivity in COVID-19 patients was statistically significant in the thrombotic subgroup (p < 0.05). FVL prevalence, CT positivity rate, history of thrombosis, and pulmonary thromboembolism complication were found to be higher in deceased COVID-19 patients (p < 0.05). Disease severity was mainly affected by FVL and not related to genotypes at the Prothrombin mutations. Overall, disease severity and development of thrombosis in COVID-19 are mainly affected by the variation within the FVL gene. Possible FVL mutation should be investigated in COVID-19 patients and appropriate treatment should be started earlier in FVL-positive patients.Publication DPYD c.1905+1G>A promotes fluoropyrimidine-induced anemia, a prognostic factor in disease-free survival, in colorectal cancer(Mary Ann Liebert, Inc, 2021-04-01) Deligönül, Adem; Aksoy, Seçil; Tezcan, Gülçin; Tunca, Berrin; Kanat, Özkan; Çubukcu, Erdem; Yılmazlar, Tuncay; Öztürk, Ersin; Egeli, Ünal; Çeçener, Gülşah; Alemdar, Adem; Evrensel, Türkkan; DELİGÖNÜL, ADEM; AKSOY, SEÇİL; TEZCAN, GÜLÇİN; TUNCA, BERRİN; Kanat, Özka; ÇUBUKÇU, ERDEM; YILMAZLAR, AHMET TUNCAY; EGELİ, ÜNAL; ÇEÇENER, GÜLŞAH; ALEMDAR, ADEM; EVRENSEL, TÜRKKAN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Onkoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Diş Hekimliği Fakültesi/Temel Bilimler Bölümü.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Biyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Onkoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Genel Cerrahi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Sağlık Bilimleri Enstitüsü.; 0000-0002-6400-4911; 0000-0002-5956-8755; 0000-0002-1619-6680; 0000-0001-8593-5101; 0000-0001-7904-883X; 0000-0002-3820-424X; HIZ-7332-2022; AAH-1420-2021; AAH-3843-2020; ESM-4544-2022; JDG-0330-2023; ABI-6078-2020; CYM-0930-2022; ETP-1691-2022; CKK-3621-2022; AAP-9988-2020; EXZ-0745-2022Background and Aim: In 10-30% of colorectal cancer (CRC) patients, toxic reactions occur after fluoropyrimidine-based chemotherapy. A dihydropyridine dehydrogenase (DPYD) gene variant, c.1905 + 1G>A, leads to intolerance to fluoropyrimidines. Due to the low frequency of this variant in many populations, the prevalence of fluoropyrimidine-induced hematologic side effects in CRC patients with the c.1905 + 1G>A variant is unclear. In this study, we investigated the prevalence of the DPYD c.1905 + 1 variants in a Turkish CRC cohort and the potential effects of these variants on fluoropyrimidine-induced hematologic side effects.Materials and Methods: The DPYD c.1905 + 1 variant was genotyped using polymerase chain reaction-restriction fragment length polymorphism analysis and confirmed by Sanger sequencing in peripheral blood samples of 100 CRC patients who received fluoropyrimidine-based chemotherapy and 60 healthy volunteers. The association of c.1905 + 1 variants with susceptibility to hematologic side effects was evaluated.Results: The DPYD c.1905 + 1G>A variant was more common in the CRC group than in the healthy control group (p = 0.001). The presence of the c.1905 + 1G>A variant was associated with thrombocytopenia (p = 0.039) and anemia (p = 0.035). CRC patients with fluoropyrimidine-induced anemia had shorter disease-free survival than CRC patients without fluoropyrimidine-induced anemia (p = 0.0009).Conclusions: Before administering fluoropyrimidine-based chemotherapy, genetic screening for the DPYD c.1905 + 1G>A variant should be performed with the aim of preventing anemia and anemia-induced complications in CRC patients.Publication Diagnostic efficiency of clinical exome solution panel in patients with hearing loss/hereditary deafness by using next generation sequencing(Springernature, 2020-12-01) ; Sağ, Şebnem Özemri; ÖZEMRİ SAĞ, ŞEBNEM; Alemdar, A.; ALEMDAR, ADEM; Yılmaz, M.; Aliyeva, L.; ALIYEVA, LAMIYA; Temel Şehime Gülsün; TEMEL, ŞEHİME GÜLSÜN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Genetik Top Anabilim Dalı.; 0000-0002-9802-0880; HIZ-7332-2022; AAH-8355-2021; AAG-8385-2021Publication Alzheimer disease associated loci: APOE single nucleotide polymorphisms in Marmara Region(MDPİ, 2024-05-01) Ismail, Aya Badeea; Dundar, Mehmet Sait; Erguzeloglu, Cemre Ornek; Ergoren, Mahmut Cerkez; Alemdar, Adem; Sag, Sebnem Ozemri; Temel, Sehime Gulsun; Alemdar, Adem; ALEMDAR, ADEM; Sağ, Şebnem Özemri; ÖZEMRİ SAĞ, ŞEBNEM; Temel, Şehime Gülsün; TEMEL, ŞEHİME GÜLSÜN; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Genetik Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Histoloji ve Embriyoloji Anabilim Dalı.Alzheimer's disease (AD) is a major global health challenge, especially among individuals aged 65 or older. According to population health studies, Turkey has the highest AD prevalence in the Middle East and Europe. To accurately determine the frequencies of common and rare APOE single nucleotide polymorphisms (SNPs) in the Turkish population residing in the Marmara Region, we conducted a retrospective study analyzing APOE variants in 588 individuals referred to the Bursa Uludag University Genetic Diseases Evaluation Center. Molecular genotyping, clinical exome sequencing, bioinformatics analysis, and statistical evaluation were employed to identify APOE polymorphisms and assess their distribution. The study revealed the frequencies of APOE alleles as follows: epsilon 4 at 9.94%, epsilon 2 at 9.18%, and epsilon 3 at 80.68%. The gender-based analysis in our study uncovered a tendency for females to exhibit a higher prevalence of mutant genotypes across various SNPs. The most prevalent haplotype observed was epsilon 3/epsilon 3, while rare APOE SNPs were also identified. These findings align with global observations, underscoring the significance of genetic diversity and gender-specific characteristics in comprehending health disparities and formulating preventive strategies.Publication Clinical and molecular evaluation of MEFV gene variants in the Turkish population: a study by the National Genetics Consortium(Springer Heidelberg, 2022-01-31) Dundar, Munis; Fahrioglu, Umut; Yildiz, Saliha Handan; Bakir-Gungor, Burcu; Temel, Sehime Gulsun; Akin, Haluk; Artan, Sevilhan; Cora, Tulin; Sahin, Feride Iffet; Dursun, Ahmet; Sezer, Ozlem; Gurkan, Hakan; Erdogan, Murat; Gunduz, C.

Caused by the mutations in the MEditerranean FeVer (MEFV) gene, it mainly affects people of Mediterranean descent with a higher incidence in the Turkish, Jewish, Arabic, and Armenian populations. As our understanding of FMF improves, it becomes clearer that we are facing with a more complex picture of FMF with respect to its pathogenesis, penetrance, variant type (gain-of-function vs. loss-of-function), and inheritance. In this study, MEFV gene analysis results and clinical findings of 27,504 patients from 35 universities and institutions in Turkey and Northern Cyprus are combined in an effort to provide a better insight into the genotype-phenotype correlation and how a specific variant contributes to certain clinical findings in FMF patients. Our results may help better understand this complex disease and how the genotype may sometimes contribute to phenotype. Unlike many studies in the literature, our study investigated a broader symptomatic spectrum and the relationship between the genotype and phenotype data. In this sense, we aimed to guide all clinicians and academicians who work in this field to better establish a comprehensive data set for the patients. One of the biggest messages of our study is that lack of uniformity in some clinical and demographic data of participants may become an obstacle in approaching FMF patients and understanding this complex disease.Publication Biomarker potential of urine miR-451 at different stages of diabetic nephropathy(Omics Int Pvt Ltd, 2016-02-01) Sayılar, Emel Işıktaş; Güllülü, Mustafa; Tuncel, Ercan; Peynirci, Hande; Alemdar, Adem; Tunca, Berrin; Egeli, Ünal; Çeçener, Gülşah; Bayındır, Murat; Coşgun, Gökhan; Sayılar, Emel Işıktaş; GÜLLÜLÜ, MUSTAFA; Tuncel, Ercan; Peynirci, Hande; ALEMDAR, ADEM; TUNCA, BERRİN; EGELİ, ÜNAL; ÇEÇENER, GÜLŞAH; Bayındır, Murat; Coşgun, Gökhan; Uludağ Üniversitesi/Tıp Fakültesi/Nefroloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Endokrinoloji ve Metabolizma Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Biyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Dahiliye Anabilim Dalı.; 0000-0002-1619-6680; 0000-0001-7904-883X; 0000-0002-3820-424X; W-2575-2017; CTG-8811-2022; EBN-7188-2022; GRY-0605-2022; ELA-3536-2022; ABI-6078-2020; AAH-1420-2021; AAP-9988-2020; CFN-0933-2022; ERH-7786-2022Aims: To evaluate the potential of urinary miR-451 as a biomarker at different stages of diabetic nephropathy.Methods: A total of 45 subjects having stage 3 chronic kidney disease (n=15) or stage 5 chronic kidney disease (n=15) and 15 healthy volunteers were included. Data on patient demographics, laboratory findings [creatinine, estimated glomerular filtration rate, urinary protein excretion] target genes and functions of the selected MicroRNAs associated with diabetic nephropathy and fold differences in the level of MicroRNA expression in blood and urine and the correlation of urine and plasma MicroRNA expression with estimated glomerular filtration rate were recorded.Results: MiR-195 expression level among stage 3 chronic kidney disease patients was higher in plasma samples compared to the control group, while it was significantly lower in the urine samples (p=0.036). In the stage 5 chronic kidney disease patient group, while the expression level was significantly higher in the plasma samples (p=0.005), urine sample expression was lower but not significantly different than the control group. Compared to the controls, miR-451 expression level was higher in the plasma samples of stage 3 chronic kidney disease patients, but significantly lower in the urine samples (p=0.019). Among the stage 5 chronic kidney disease patients, there was significantly higher level of expression in plasma samples (p=0.007) and significantly lower expression in urine samples (p=0.022) than the control group.Conclusions: Our study is original with its investigation of MicroRNA expressions at different stages of chronic kidney disease. Especially the statistically significant changes in the expression of miR-195 and miR-451 make these MicroRNAs come forward as good noninvasive biomarker candidates.
