Publication The effect of exosomes released from apheresis plateletconcentrates under the impact of gamma irradiation and storage time upon platelet aggregation and hemostasis(Simtipro Srl, 2023-05-01) Bal, Salih Haldun; Sağdilek, Engin; Karacay, Mehmet; Kızmaz, Muhammed A.; Kumaş, Levent T.; Can, Fatma E.; Yıldırım, Muzaffer; Canavar-Yıldırım, Tuğçe; Kosay-Gülkaya, Deniz; Yöyen-Ermiş, Diğdem; Budak, Ferah; Heper, Yasemin; Gürsel, İhsan; Oral, Haluk B.; BAL, SALİH HALDUN; SAĞDİLEK, ENGİN; Karaçay, Mehmet; Kizmaz, Muhammed A.; Kumaş, Levent T.; Can, Fatma E.; Kosay-Gülkaya, Deniz; YÖYEN ERMİŞ, DİĞDEM; BUDAK, FERAH; HEPER, YASEMİN; ORAL, HALUK BARBAROS; Tıp Fakültesi; Dr. Raşit Durusoy Kan Bankası; 0000-0001-7625-9148 ; 0000-0001-5871-8769 ; 0000-0001-5334-7911 ; 0000-0002-1953-7735; 0000-0002-1953-7735; HJY-9001-2023; AAH-4397-2021; JHB-7829-2023; HKN-2347-2023; FHB-1791-2022; JSL-7718-2023; HJH-5312-2023; HJH-5217-2023; IYU-6844-2023; AAH-3888-2021; IZP-9398-2023; HOK-0035-2023; K-7285-2012Background -Blood components should be gamma-irradiated (& gamma;-IR) in order to prevent transfusion-associated graft-versus-host disease. The aim of this study is to determine the effect of & Gamma;-IR and storage time on the exosomes released from apheresis platelet concentrates (aPC) and to investigate their impact on the maximum platelet aggregation (MPA) and hemostasis. Materials and methods -Eight units of aPC were included in this study. These were divided into four equal portions. Two portions were irradiated before storage while the other two were not. Thus, irradiated and non-irradiated aPC samples for storage Days 0 (D0) and 5 (D5) were obtained. Exosomes were isolated from these samples using a commercial kit and were evaluated to ascertain their parent cells by flow cytometry. For the following steps, exosomes were pooled according to their features. Pooled exosomes were then used for aggregometry and thromboelastography. Results -Platelet-derived exosome (PD-EX) levels decreased in D5 compared to D0 in NI-aPC, whereas granulocyte-derived exosome (GD-EX) levels increased. Exosome pools had no effect on MPA compared to saline groups. Exosome pools decreased the time to initial fibrin formation (R), whereas they increased the rate of clot formation (& alpha;-angle) and coagulation index (CI) compared to saline groups. Discussion -Storage time and & Gamma;-IR each have almost the opposite effects on PD-EX and GD-EX. Exosomes have no impact on MPA, but enhance the clot strength. The impact of exosomes on aPC quality and effectiveness can be ignored or considered as a positive effect.Publication The impact of gamma irradiation on exosome profiles and electrolyte levels in apheresis platelet concentrates(Wiley, 2021-08-01) Bal, Salih Haldun; Karaçay, Mehmet; Kızmaz, Muhammed Ali; Kumaş, Levent Tufan; Can, Fatma Ezgi; Gülkaya, Deniz Koşay; Ermiş, Diğdem Yöyen; Budak, Ferah; Heper, Yasemin; Oral, Haluk Barbaros; BAL, SALİH HALDUN; Karaçay, Mehmet; Kızmaz, Muhammed Ali; Kumaş, Levent Tufan; Can, Fatma Ezgi; Gülkaya, Deniz Koşay; YÖYEN ERMİŞ, DİĞDEM; BUDAK, FERAH; HEPER, YASEMİN; ORAL, HALUK BARBAROS; Tıp Fakültesi; İmmunoloji Ana Bilim Dalı; 0000-0001-5334-7911; 0000-0001-7625-9148; 0000-0003-0463-6818; JSL-7718-2023; HKN-2347-2023; K-7285-2012; F-4657-2014; IZP-9398-2023; KBR-5535-2024; JHB-7829-2023; FHB-1791-2022; CSL-9726-2022; GYL-2038-2022; HOK-0035-2023; CTY-9474-2022Publication The SOCS-1-1478CA/del functional polymorphism (rs33989964) is associated with gastric cancer but is unrelated to overall survival(Springer, 2023-02-13) Hartavi, Mustafa; Ölmez, Ömer Fatih; Oral, Barbaros; Çubukçu, Erdem; Nak, Selim Giray; Hartavi, Mustafa; Ölmez, Ömer Fatih; ORAL, HALUK BARBAROS; ÇUBUKÇU, ERDEM; NAK, SELİM GİRAY; Tıp Fakültesi; İmmünoloji Ana Bilim Dalı; CUI-5353-2022; DJG-4827-2022; DLT-1037-2022; ETP-1691-2022; FQM-3662-2022BackgroundIn vitro studies have shown that the functional - 1478CA > del polymorphism (rs33989964) of the suppressor of cytokine signaling (SOCS)-1 gene is associated with an altered trascriptional activity. Here, we sought to examine the potential association of this polymorphism with the risk of gastric cancer (GC) and to analyze its prognostic impact on overall survival (OS).Materials and methodsThe study cohort consisted of 74 Turkish patients with GC and 52 healthy controls. Genotyping of the SOCS-1 -1478CA > del polymorphism was carried out using restriction fragment length polymorphism analysis.ResultsAfter allowance of age and sex, multivariable logistic regression analysis revealed that the carriage of the del allele of the SOCS-1 -1478CA > del polymorphism was independently associated with an increased risk of GC (odds ratio = 6.78, 95% confidence interval = 3.24-10.99, P < 0.001). Kaplan-Meier analysis revealed no significant differences in OS for patients harboring at least one del allele of rs33989964 compared with CA/CA homozygotes (log-rank test, P = 0.17).ConclusionWhile the SOCS-1 -1478CA > del polymorphism is significantly associated with the risk of GC in the Turkish population, it does not affect OS.Publication Phenotypes and functions of low(er)-density neutrophils (LDNs) in early childhood and children(Wiley, 2021-08-01) Dombaz, Fatma; Karaçay, Mehmet; Etgü, Onur; Kızmaz, Muhammed Ali; Şimşek, Abdurrahman; Çağan, Eren; Pınar, İbrahim Ethem; Bal, Salih Haldun; Özkocaman, Vildan; Özkalemkaş, Fahir; Budak, Ferah; Oral, Halük Barbaros; Ermiş, Diğdem Yöyen; Dombaz, Fatma; Karaçay, Mehmet; Etgü, Onur; Kızmaz, Muhammed Ali; ŞİMŞEK, ABDURRAHMAN; PINAR, İBRAHİM ETHEM; BAL, SALİH HALDUN; ÖZKOCAMAN, VİLDAN; ÖZKALEMKAŞ, FAHİR; BUDAK, FERAH; ORAL, HALUK BARBAROS; YÖYEN ERMİŞ, DİĞDEM; Sağlık Bilimleri Yüksekokulu; İmmünoloji Ana Bilim Dalı; Hematoloji Bilim Dalı; 0000-0001-7625-9148 ; 0000-0001-9907-1498 ; 0000-0001-8850-0269 ; 0000-0001-5334-7911 ; DWR-5356-2022; JHB-7829-2023; JIJ-1849-2023; HKN-2347-2023; AAG-7381-2021; KBR-5535-2024; FQG-8981-2022; JIW-1248-2023; IZP-9398-2023; K-7285-2012; GYL-2038-2022Publication Il-21: A potential biomarker for diagnosis and predicting prognosis in covid-19 patients(European Respiratory Society Journals, 2021-09-05) Öztürk, Nilüfer Aylin Acet; Ursavaş, Ahmet; Dilektaşlı, Aslı Görek; Demirdöğen, Ezgi; Coşkun, Funda; Ediger, Dane; Uzaslan, Esra; Yöyen-Ermiş, Diğdem; Karaca, Mert; Terzi, Orkun; Bayram, Merve; Ömer, Dilara; Yiğitliler, Büşra; Yurttaş, Ahmet; Maharramov, Shahriyar; Çelik, Gamze; Oral, Barbaros; Karadağ, Mehmet; ACET ÖZTÜRK, NİLÜFER AYLİN; URSAVAŞ, AHMET; GÖREK DİLEKTAŞLI, ASLI; DEMİRDÖĞEN, EZGİ; COŞKUN, NECMİYE FUNDA; EDİGER, DANE; UZASLAN, AYŞE ESRA; YÖYEN ERMİŞ, DİĞDEM; KARACA, MERT; TERZİ, ORKUN ERAY; BAYRAM, MERVE; ÖMER TOPÇU, DİLARA; YURTTAŞ, AHMET; ORAL, HALUK BARBAROS; KARADAĞ, MEHMET; MAHARRAMOV, SHAHRİYAR; YAZICI, GAMZE; Tıp Fakültesi; 0000-0002-6375-1472; 0000-0002-7400-9089; 0000-0003-3604-8826; 0000-0002-2954-4293; 0000-0001-5871-8769; 0000-0002-9027-1132; AAG-8744-2021; JPK-7012-2023; AAH-3888-2021; AAE-9142-2019; AAI-3169-2021; AAD-1271-2019Publication Evaluation of the roles of regulatory B (Breg) cells and B cell exhaustion in COVID-19(Wiley, 2021-08-01) Budak, Ferah; Çağan, Eren; Kızmaz, Muhammed Ali; Şimşek, Abdurrahman; Dombaz, Fatma; Tezcan, Gülçin; Asan, Ali; Bal, S.
