Öğe Biocompatibility of biodentine™ ® with periodontal ligament stem cells: In vitro study(MDPI Multidisciplinary Digital Publishing Institute, 2020) Abuarqoub, Duaa A.; Aslam, Nazneen; Jafar, Hanan D.; Harfil, Zakariya Abu; Awidi, Abdalla S.Biodentine™ is a tricalcium silicate-based cement material that has a great impact on different biological processes of dental stem cells, compared to other biomaterials. Therefore, we aimed to investigate the optimum biocompatible concentration of Biodentine™ with stem cells derived from periodontal ligament (hPDLSCs) by determining cell proliferation, cytotoxicity, migration, adhesion and mineralization potential. hPDLSCs were treated with Biodentine™ extract at different concentrations; 20, 2, 0.2 and 0.02 mg/mL. Cells cultured without Biodentine™ were used as a blank control. The proliferation potential of hPDLSCs was evaluated by MTT viability analysis for 6 days. Cytotoxicity assay was performed after 3 days by using AnnexinV/7AAD. Migration potential was investigated by wound healing and transwell migration assays at both cellular and molecular levels. The expression levels of chemokines CXCR4, MCP-1 and adhesion molecules FGF-2, FN, VCAM and ICAM-1 were measured by qPCR. The communication potentials of these cells were determined by adhesion assay. In addition, mineralization potential was evaluated by measuring the expression levels of osteogenic markers; ALP, OCN, OPN and Collagen type1 by qPCR. Our results showed significant increase in the proliferation of hPDLSCs at low concentrations of Biodentine™ (2, 0.2 and 0.02 mg/mL) while higher concentration (20 mg/mL) exhibited cytotoxic effect on the cells. Moreover, 2 mg/mL Biodentine™ showed a significant increase in the migration, adhesion and mineralization potentials of the derived cells among all concentrations and when compared to the blank control. Our findings suggest that 2 mg/mL of Biodentine™ is the most biocompatible concentration with hPDLSCs, showing a high stimulatory effect on the biological processes.Öğe Sağlık öğrencilerinde aşı tereddüdü(Hayat Sağlık ve Sosyal Hizmetler Vakfı, 2021) Çetin, Ali Osman; Şaşmaz, Asiye; Kurtuluş, Dilara; Badur, İsa; Balkan, İlker İnanç; Owiw, Mohannad; Öge, Ali Emre; Atak, Muhammed; Duman, Alparslan; Altunel, Ayşe Nur; Akkoyun, Meryem; Korkmaz, Beyza; Çelik, Ahmet Ali; Özdilek, Yusuf İhsan; Keleş, Huzeyfe; Az, Adem; Ankaralı, HandanAmaç: Bu çalışmada İstanbul’da sağlık alanında (tıp, diş hekimliği, eczacılık, hemşirelik, ebelik, fizik tedavi ve rehabilitasyon, diyetisyenlik, odyoloji, sağlık yönetimi) yükseköğrenim görmekte olan öğrencilerin aşı tereddüdü düzeyini, dağılımını ve öğrenim yılına göre değişimini ortaya koymak amaçlanmıştır. Yöntem: Çalışmamız bir anket çalışmasıydı ve belirlenen fakülte ve bölümlerde kayıtlı (T.C. Ölçme, Seçme ve Yerleştirme Merkezi 2019 verilerine göre) 17.488 üniversite öğrencisinin %10’una ulaşmak hedeflendi. Anket Google Formlar® platformunda çevrimiçi olarak gerçekleştirildi. Bulgular: Çalışma toplam 1559 öğrenci içerdi. Öğrencilerin %15,1’i “Gerekli durumlarda (riskli maruziyet, rutin korunma) kendinize tereddüt etmeden aşı yaptırabiliyor musunuz?” sorusuna “Hayır” yanıtını verdi. Bu oranın öğrenim yılı arttıkça azaldığı görüldü (?2=21,523; p<0,001). Aşı tereddüdü tıp (%9,2) ve ebelik (%11,2) öğrencilerinde en düşük, fizik tedavi (%31,3) ve odyoloji (%30,4) öğrencilerinde ise en yüksek düzeydeydi. Aşı tereddüdü düzeyi eğitim düzeyine göre anlamlı farklılık gösterdi (?2=63,034; p<0,001); öğrenim yılı arttıkça aşılara duyulan güven artmaktaydı. Ancak öğrencilerin %78,6’sının grip aşısına dair tereddütleri olduğu ve bunun öğrenim yılı ile anlamlı biçimde değişmediği (p=0,053) görüldü. Kızamık ve suçiçeği aşıları ile ilgili tereddütlerin başlıca nedeni “hastalığı geçirmenin aşı olmaktan daha koruyucu” olduğu düşüncesi; hepatit B, tetanos ve kuduz aşıları ile ilgili tereddütlerin başlıca nedeni ise “yan etkilerden duyulan kaygı” idi. Sonuç: Sağlık çalışanları arasındaki aşı tereddüdü toplumun aşılanma tutumu üzerinde oldukça etkilidir. Öğrenim yılı arttıkça azalmakla birlikte, sağlık öğrencilerinde aşı tereddüdü düzeyi yüksek görünmektedir. Bu tereddütlerin yükseköğretim sırasında belirlenip doğru bilgilendirmeyle giderilmesi son derece önemlidir. Sağlık yükseköğretimindeki içerik ve yöntemler bu gözle yeniden değerlendirilmelidir.Öğe Stem cell-based therapies for temporomandibular joint osteoarthritis and regeneration of cartilage/osteochondral defects: A systematic review of preclinical experiments(Elsevier Science Ltd, 2022) Matheus, H. R.; Özdemir, Ş. D.; Guastaldi, F. P. S.Objectives: The aim of this systematic review was to assess the effects of stem cell-based therapies on the treatment of Temporomandibular Joint Osteoarthritis (TMJ-OA) and the regeneration of cartilage/ osteochondral defects. Methods: Data on preclinical studies evaluating the effectiveness of stem cell-based therapies for treating Temporomandibular Disorders (TMDs) were extracted from PubMed, Web of Science, and Cochrane Li-brary and the grey literature by three independent reviewers. A manual search was performed in the databases, the reference list of review studies, and relevant journals in the field. Compliance with the ARRIVE guidelines was evaluated for quality assessment. SYRCLE's risk of bias tool for animal experi-mental studies was assessed to define internal validity. Results: After applying the inclusion and exclusion criteria, 10 studies were included in the qualitative synthesis. Regardless of cell origin, stem cell-based therapeutic approaches induced protective, anti-inflammatory, and chondroregenerative potential in the treatment of TMJ-OA. Regeneration of the cartilage layer on the surface of the condyle was achieved when stem cells were directly flushed into the defect or when delivered within a carrier. Conclusion: Stem cell-based therapies may be considered a promising approach for the treatment of TMJ-OA and for the regeneration of full-thickness cartilage and osteochondral defects in the TMJ. Human studies shall be performed to validate these results found in animals.Öğe The effect of corrective and therapeutic exercises on bleeding volume and severe menstrual pain in non-athletic women(Taylor and Francis Ltd., 2021) Lorzadeh, Nahid; Kazemirad, Yasaman; Kazemirad, NastranThe aim of this study was to determine the relationship between lumbar lordosis and severe menstrual pain and bleeding for the improvement of the health status in women. This was a quasi-experimental study where the effects of a training program, (based on correctional and therapeutic exercises, on primary dysmenorrhoea and menstrual bleeding in women with hyper-lordosis) was determined. The severity of menstrual pain was evaluated by use of a questionnaire. There was a significant incidence of neurological pain, which was not reduced in the control group (who had no exercise). There was a significant relationship between the severity of menstrual pain and hyper-lordosis. In the intervention group, there was a significant decrease in the severity of menstrual pain following 12 weeks of exercise. Hyper-lordosis can be improved by performing corrective exercises and strengthening the abdominal muscles.Impact statementWhat is already known on this subject? Exercise is positively associated with changes in the menstrual cycle and has beneficial effects on menstruation. What do the results of this study add? This research determines the relationship between lumbar lordosis and severe menstrual pain and the association of severe menstrual bleeding, in order to take effective corrective actions to improve women’s health. What are the implications of these findings for clinical practice and/or further research? Hyper-lordosis can be improved by corrective exercises and strengthening of the abdominal muscles.Öğe Treatment of genital herpes using olive leaf extract(Wiley, 2021) Lorzadeh, Nahid; Kazemirad, Yasaman; Kazemirad, NastranGenital herpes is one of the sexually transmitted diseases that is reported with a greater incidence of primary and secondary recurrence. In this study, olive leaf extract was used for its antiviral properties to treat the infection. The randomized-clinical trials using such a therapeutic approach are required in this field.
