Faculty, Staff and Student Publications

Fruit trees and other fruiting hardwood perennials are economically valuable, and there is interest in developing improved varieties. Both conventional breeding and biotechnology approaches are being utilized towards the goal of developing advanced cultivars. Increased knowledge of the effectiveness and efficiency of biotechnology approaches can help guide use of the CRISPR gene-editing technology. Here, we examined CRISPR-Cas9-directed genome editing in the valuable commodity fruit tree Malus x domestica (domestic apple). We transformed two cultivars with dual CRISPR-Cas9 constructs designed to target two AGAMOUS-like genes simultaneously. The main goal was to determine the effectiveness of this approach for achieving target …

Turkish Journal of Medical Sciences

Background/aim: T-cell acute lymphoblastic leukemia (T-ALL) is a form of leukemia characterized by the proliferation of immature T lymphocytes. NOTCH1 is one of the most frequently mutated genes in T-ALL. NOTCH1 expression in T-cell development depends on plant homeodomain finger protein 6 (PHF6), which plays a tumor suppressor role in T-ALL. Several studies have shown that PHF6 expression is essential for NOTCH1 expression. Therefore, whether posttranslational modification of PHF6 plays a role in the regulation of NOTCH1 expression and T-ALL cell line proliferation was investigated herein. Materials and methods: The amino acid sequence of PHF6 was analyzed and it was …

Background/aim: Immunoglobulin A vasculitis (IgAV) is one of the most common types of vasculitis in children. The aims of this study were to investigate the clinical characteristics of the disease, and the effects of age and sex on the clinical course in children with IgAV. Materials and methods: This was a retrospective study including pediatric patients diagnosed with IgAV who attended follow-ups at the pediatric rheumatology department of a tertiary healthcare institution between January 1997 and December 2020. The patients were grouped and compared according to sex and age at diagnosis (<7 years vs. ?7 years). Results: The study included 709 children with IgAV, 392 (55.3%) of whom were male. The mean age at diagnosis was 7.9 ± 3.2 years. The most common disease onset season was autumn (31.2%). Upper respiratory infections (27.8%) were the most common predisposing factors. Gastrointestinal system (GIS), joint, and renal involvement were observed in 52.8%, 47.5%, and 17.5% of patients, respectively. Renal involvement, GIS involvement, and disease relapse were significantly more common among those diagnosed after 7 years of age compared to those diagnosed before the age of 7 (p < 0.001, p = 0.033, and p < 0.001, respectively). Scrotal involvement and subcutaneous edema were more common among those diagnosed at younger than 7 years compared to those aged ?7 years at diagnosis (p < 0.001 and p = 0.016, respectively). GIS involvement was more frequently seen in males compared to females (p = 0.046). Conclusion: It was demonstrated that being ?7 years of age at diagnosis or being a male were associated with higher likelihood of renal and GIS involvement in children with IgAV.

Comparison Of The Efficiencies Of Intrathecal And Intraganglionic Injections In Mouse Dorsal Root Ganglion, Mehmet Şeri̇f Aydin, Esra Nur Yi̇ği̇t Oct 2023

Comparison Of The Efficiencies Of Intrathecal And Intraganglionic Injections In Mouse Dorsal Root Ganglion, Mehmet Şeri̇f Aydin, Esra Nur Yi̇ği̇t

Turkish Journal of Medical Sciences

Background/aim: Dorsal root ganglia (DRG) are structures containing primary sensory neurons. Intraganglionic (IG) and intrathecal (IT) applications are the most common methods used for viral vector transfer to DRG. We aim to compare the efficiencies and pathological effects of IT and IG viral vector delivery methods to DRG, through in vivo imaging. Materials and methods: Mice were divided into four groups of six each: IT, IG, IT-vehicle, and IG-vehicle. Adeno-associated virus (AAV) injection was performed for EGFP expression in IT/IG groups. DRGs were made visible through vertebral window surgery and visualized with multiphoton microscopy. After imaging, spinal cords and DRGs …

Serum Myosin-Binding Protein C Levels: A New Marker For Exclusion Of Preterm Birth?, Eli̇f Yildiz, Fatma Ketenci̇ Gencer, Burcu Ti̇mur, Hakan Ti̇mur

Turkish Journal of Medical Sciences

Background/aim: To evaluate whether there is a relationship between serum myosin-binding protein C (MyBP-C) levels measured in the first trimester and the timing of delivery, and, if a relationship is detected, the potential of this relationship in distinguishing between preterm and term labor. Materials and methods: This prospective case-control study was conducted with 701 pregnant women who applied to the Obstetrics Outpatient Clinic of Gaziosmanpaşa Training and Research Hospital in the first trimester, between 11 and 14 gestational weeks. MyBP-C serum samples from the first trimester were stored under appropriate conditions until the time of delivery. Of these pregnant women, …

Turkish Journal of Medical Sciences

Background/aim: People living with human immunodeficiency virus (PLWH) are getting older. Age-related comorbidities in PLWH result in polypharmacy and increase the risk for potential drug-drug interactions (pDDIs). This study aimed to evaluate how the rate of pDDIs would change if the treatment of patients receiving different combined antiretroviral therapies (ARTs) were theoretically changed with dolutegravir/lamivudine (DTG+3TC) or cabotegravir/rilpivirine (CAB+RPV). Materials and methods: This study was conducted at the infectious disease outpatient clinic of a university hospital as a follow-up of a previous study. The data of PLWH receiving at least 1 comedication other than antiretrovirals (ARVs) were retrospectively reviewed and …
