    Synthesis and Biological Study of Novel Indole-3 Derivatives as Src Kinase and Glutathione S-Transferase Inhibitors
    (Bentham Science Publ Ltd, 2013) Kurt, Z. Kilic; Aydin, D.; Isgor, Y. G.; Isgor, B. S.; Olgen, S.
    The aim of this study is to design and synthesize novel dual inhibitors of Src protein tyrosine kinase (PTK) and Glutathione S-transferases (GSTs), as a potential drug lead with therapeutic efficacy on cancer and immune disorders. The biological activity profiling of small molecule inhibitors via miniaturized biochemical techniques compatible with medium throughput screening and focused screening methodologies were performed. To determining the effects of small molecule inhibitors on Src kinase and Phase II detoxification enzyme GST isozymes in liver homogenates used to verify their roles in drug resistance mechanism for cancer chemotherapeutics. In this study, 14 indole-3-imine-2-on and N-benzyl indole-3-imine-2-on derivatives were synthesized for dual activities against Src and GST. The chemical structures and purities of compounds were verified by IR, H-1 NMR, MASS spectroscopy, and elemental analysis. The compounds 2, 3 and 9 are found slightly active against both enzyme Src and GST.

    Interprofessional Simulation-Based Training in Gynecologic Oncology Palliative Care for Students in the Healthcare Profession: a Comparative Randomized Controlled Trial
    (Churchill Livingstone, 2020) Uslu-Sahan, Fatma; Terzioglu, Fusun
    Background: Preprofessional palliative care education may be inadequate, leaving a gap in health professional students' knowledge and understanding of managing patients with gynecologic cancer and their families. Interprofessional simulation-based training may be useful in helping health professional students gain the necessary skills required for palliative care. Objective: This study aimed to determine the effectiveness of different simulation methods used for interprofessional training on gynecologic oncology palliative care knowledge, interdisciplinary education perceptions, and teamwork attitudes of health professional students and to compare these methods. Design: A comparative randomized controlled trial was conducted with a pre-test and two post-tests. Settings: This study was conducted at a university in Ankara, Turkey, in 2016-2017. Participants: A convenience sample of 84 interprofessional students (nursing, medical, nutrition-dietician, and social work) was used in the study. Methods: Students were stratified by their profession and randomized by four blocks into high-fidelity simulation, hybrid simulation, and a control group. Data were collected using a semi-structured questionnaire form, palliative care knowledge test, interdisciplinary education perception scale, and teamwork attitudes questionnaire. Results: The high-fidelity simulation and hybrid simulation groups improved their palliative care knowledge, interdisciplinary education perception, and teamwork attitudes from pre-test to first and second post-tests compared to the control group. Conclusion: The introduction of high-fidelity simulation and hybrid simulation or hybrid simulation-based interprofessional training in undergraduate education can increase students' palliative care knowledge, interdisciplinary education perception, and teamwork attitudes. Training programs that are used together with highfidelity simulation and hybrid simulation applications in interdisciplinary training should be integrated into the undergraduate curricula of future cooperating health professions.

    Cannabinoids as Prospective Anti-Cancer Drugs: Mechanism of Action in Healthy and Cancer Cells
    (Springer, 2023) Boyacıoğlu,Ö.; Korkusuz,P.
    Endogenous and exogenous cannabinoids modulate many physiological and pathological processes by binding classical cannabinoid receptors 1 (CB1) or 2 (CB2) or non-cannabinoid receptors. Cannabinoids are known to exert antiproliferative, apoptotic, anti-migratory and anti-invasive effect on cancer cells by inducing or inhibiting various signaling cascades. In this chapter, we specifically emphasize the latest research works about the alterations in endocannabinoid system (ECS) components in malignancies and cancer cell proliferation, migration, invasion, angiogenesis, autophagy, and death by cannabinoid administration, emphasizing their mechanism of action, and give a future perspective for clinical use. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

    Detection of Toxoplasma Gondii and High-Risk Human Papillomaviruses in FFPE Malignant and Benign Breast Lesions Using Real-Time Pcr
    (Dove Medical Press Ltd, 2025) Usluca, Selma; Bakir, Ayfer; Arikok, Ata Turker; Korkut, Gizem; Yagiz, Gulsah Ceylan; Alper, Murat
    Objective: Breast cancer is the most prevalent malignancy among women. In recent years, it has been suggested that various pathogens such as Toxoplasma gondii (T. gondii) and human papillomavirus (HPV) may play a potential role in the development of breast cancer. This study aimed to determine the prevalence of T. gondii and HPV infections in formalin-fixed paraffin-embedded tissue samples of breast cancer patients using real-time PCR. Methods: The study included 136 paraffin-embedded biopsy samples with w confirmed malignant breast tumor diagnosis and 50 breast tissue samples diagnosed as benign breast lesions, serving as controls. The presence of T. gondii DNA and high-, medium-, and low-risk HPV genotype DNAs were investigated using the real-time PCR method. First, deparaffinization was performed using xylene and alcohol, followed by DNA extraction and real-time PCR amplification. Results: The most common histopathological types of malignant breast carcinoma were invasive carcinoma (n=82; 60.3%), invasive lobular carcinoma (n=26; 19.1%), invasive ductal carcinoma (n=8; 5.9%), and mixed invasive carcinoma (n=8; 5.9%). According to the Modified Bloom-Richardson classification, 55.15% of malignant breast tumor samples were grade 2, 32.4% were grade 3, and 12.5% were grade 1. Real-time PCR analysis did not detect T. gondii DNA or HPV DNA in any of these samples. Conclusion: Our findings do not support a role of T. gondii and HPV in breast cancer development. To better understand the possible relationship between breast cancer and these pathogens, further studies with larger sample sizes, diverse diagnostic methods, and broder geographical coverage are necessary.

    Predictors of Parenting Stress in Parents of Children With Cancer
    (Elsevier Sci Ltd, 2021) cinar, Sevil; Boztepe, Handan; Ay, Ayse; Yilmaz, Pinar; Gullu, Hafize; Karadavut, Burcu; Akyuz, Canan
    Purpose: In the present study, we investigated the parenting stress experienced by parents of children with cancer and the influencing factors. Method: This was a cross-sectional and descriptive correlational study that consisted of parents of 136 children in the age group of 0-18 years who were followed up for cancer in the outpatient clinics and services of a university hospital in Turkey. Parenting Stress Index, Burden Interview, Multidimensional Scale of Perceived Social Support, Marital Life Satisfaction Scale, and Ways of Coping Questionnaire were used to collect the data. Results: No statistically significant difference was found between the parenting stress mean scores and gender of the parents of children with cancer (t = -0.350; P = 0.727). The results of the present study showed that the economic status (t = -4.16; P = 0.000), parents' physical (t = 3.606; P = 0.000) and mental health status after the child is diagnosed (t = 5.647; P = 0.000), accompanying mental health problems of the child (t = 2.567; P = 0.011), and diagnosis of children at a young age (t = -2.776; P = 0.006) increased the parenting stress of the parents. Conclusions: Nursing interventions can reduce parental stress by providing sufficient care and support during the disease process.
