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 Molecular determining of HIV-1 with the presence of hepatitis B virus and hepatitis C virus co-infections(John Wiley & Sons Ltd, 2018-10-01) Sayan, M.; Özgüler, M.; Yıldırım, F.

Herein, we aimed to evaluate prognostic factors and clinical scores for confirmed COVID-19 patients in a tertiary care hospital in the Bursa region of Turkey. Methodology: Patients who had been diagnosed with COVID-19 microbiologically and/or radiologically between March and October 2020 in a tertiary-care university hospital were enrolled retrospectively. Adult patients (>= 18 years) with a clinical spectrum of moderate, severe, or critical illness were included. The dependent variable was 30-day mortality and logistic regression analysis was used to evaluate any variables with a significant p value (< 0.05) in univariate analysis. Results: A total of 257 patients were included in the study. The mortality rate (30-day) was 14.4%. In logistic regression analysis, higher scores on sequential organ failure assessment (SOFA) (p < 0.001, odds ratio (OR) = 1.86, 95% CI = 1.42-2.45) and CURB-65 pneumonia severity criteria (p = 0.001, OR = 2.60, 95% CI = 1.47-4.57) were found to be significant in predicting mortality at admission. In deceased patients, there were also significant differences between the baseline, day-3, day-7, and day-14 results of D-dimer (p = 0.01), ferritin (p = 0.042), leukocyte (p = 0.019), and neutrophil (p = 0.007) counts. Conclusions: In our study of COVID-19 patients, we found that high SOFA and CURB-65 scores on admission were associated with increased mortality. In addition, D-dimer, ferritin, leukocyte and neutrophil counts significantly increased after admission in patients who died.Publication Experience of pandemic influenza A (H1N1) 2009(Aves, 2012-12-01) Kebabçı, Nesrin; Akalın, Halis; Bölük, Gülçin; Oğuz-Ayarcı, Ayşe; Kazak, Esra; Topal, Uğur; Yorulmaz, Hakan; Akköse, Şule; Özvatan-Şener, Tülay; Aslan, Emel; Köprücüoğlu, Duygu; Heper, Yasemin; Yılmaz, Emel; Kahveci, Ferda; Mıstık, Reşit; Helvacı, Safiye; Kebabçı, Nesrin; AKALIN, EMİN HALİS; Bölük, Gülçin; Oğuz-Ayarcı, Ayşe; KAZAK, ESRA; Topal, Uğur; Yorulmaz, Hakan; Akköse, Şule; Özvatan-Şener, Tülay; Aslan, Emel; Köprücüoğlu, Duygu; HEPER, YASEMİN; YILMAZ, EMEL; KAHVECİ, FERDA ŞÖHRET; Mıstık, Reşit; Helvacı, Safiye; Uludağ Üniversitesi/Tıp Fakültesi/İnfeksiyon Hastalıkları ve Klinik Mikrobiyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/İç Hastalıkları Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Acil Tıp Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Hastalıkları Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Anesteziyoloji ve Reanimasyon Anabilim Dalı.; 0000-0001-7530-1279; 0000-0002-3894-1231; 0000-0003-4820-2288; FCW-3335-2022; AAU-8952-2020; KFT-0453-2024; FOZ-1105-2022; AAG-8459-2021; JLP-0593-2023; EIO-1059-2022; EJV-1316-2022; FQE-4671-2022; EJJ-4181-2022; FGO-0266-2022; AAH-6506-2021; HJZ-6992-2023; AAG-9356-2021; DFY-3761-2022; EXQ-2687-2022Objective: Pandemic influenza A (H1N1) 2009 first appeared in April, 2009 in Mexico and affected the entire world. The objective of this study is to analyze epidemiological, clinical and laboratory findings of probable or confirmed pandemic inluenza A (H1N1) 2009 adult cases who were admitted to our clinic.Methods: Eighty-five patients with pandemic influenza A (H1N1) 2009 admitted to Uludag University Hospital between November 3, 2009 and January 22, 2010 were retrospectively evaluated.Results: Of the 85 cases, 44 (51.8%) were females and 41 (48.2%) were males. The median age was 33 (17-82). 16 of cases (18.8%) were assessed as accurate, and 69 (81.2%) as probable cases of influenza. Pneumonia was diagnosed in 17 (20%) patients by evaluating clinical findings and chest X-ray. Eleven of the cases were treated in the Intensive Care Unit. Seventy-one (83.5%) of the cases were treated by oseltamivir. Mean duration of treatment was 10 days. The mortality rate of the cases was 4.7%.Conclusions: Pandemic influenza A (H1N1) 2009 perpetuates its epidemic potential as in the past years. The disease is frequently accompanied by pneumonia during its course.Publication A case of brucellosis with subcutaneous abscess(Aves, 2006-12-01) Güler, Hicran; Mistik, Reşit; Kabas, Mine; Heper, Yasemin; HEPER, YASEMİN; Hakyemez, Bahattin; HAKYEMEZ, BAHATTİN; Helvacı, Safiye; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Mikrobiyoloji ve Enfeksiyon Hastalıkları Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; AAI-2318-2021; AAH-6506-2021A case of brucellosis with subcutaneous abscess adjacent to the parotis gland is presented in this study.

Despite the exact mechanisms of these changes are not known, it is thought that ABT causes a decrease of CD4/CD8 ratio in the recipient. This study aimed to determine the CD4/CD8 ratio in stored erythrocyte suspensions (ES) and to obtain new information about TRIM mechanisms.Materials and Methods: Whole blood components used in our study were collected from 10 healthy volunteers. ES' obtained from whole blood were divided into three equal aliquots. Test samples which were related to 0th, 21st and 42nd storage days were prepared from these aliquots. CD3, CD4 and CD8 surface markers in peripheral blood mononuclear cells were investigated with flow-cytometer in these test samples.Results: Our data were evaluated according to storage days. Decrease of CD3 (p=0,001), CD4 (p<0,001), CD8 (p=0,012) expressing mononuclear blood cells and helper T cells in 21st-day samples, CD4 (p=0,035) and CD8 (p=0,017) expressing cells in 42nd-day samples compared to Day 0 samples and increase of CD3 (p=0,027) expressing cells in 42nd-day samples compared to 21st-day samples were found statistically significant.Conclusion: In our study, we did not find any significant change in the ratio of CD4(+)/CD8(+) cells in ES. Detailed studies can help us to obtain more comprehensive knowledge on this field.
