Öğe Evaluation of the Golden Ratio in Nasal Conchae for Surgical Anatomy(SAGE, 2021) Petekkaya, Emine; Ulusoy, Mahinur; Bagheri, Hassan; Şanlı, Şükrü; Ceylan, Mehmet Seyit; Dokur, Mehmet; Karadağ, MehmetPurpose: The golden ratio is reached by the fractal model of the number sequence which is known as the ‘‘Fibonacci series’’ and has a convergent ratio of approximately 1.618 between 2 consecutive Fibonacci numbers. Golden ratio relationships have been shown in several plants in the nature and several organs and structures in the human body. The conchae, which form an important part of the nasal valve, have a special geometric significant in terms of providing turbulence to the laminar airflow that passes to the nasal cavity. Methods: This study made golden ratio calculations on 34 adults aged 20 to 45 years over computed tomography (CT) images. Totally, 34 volunteers (male, n ¼ 18 and female, n ¼ 16) with no nasal pathologies participated in the study. Using Adobe Photoshop, golden ratio calculations were made by applying the Fibonacci spiral on the images that best showed the conchae and meatuses on the CT images. Results: The intersection points of the spiral that was projected on the inferior and middle nasal concha were determined as S0, S1, S2, S3, and S4. The distances of S0-S1, S1-S2, S2-S3, and S3-S4 were measured. The concha measurements of the women showed significantly similar values to the golden ratio constant of *1.618 in the RS3/S4 and LS3/S4 measurements. Conclusion: We found that the S3/S4 region that captured the golden ratio in our study corresponds to the base part of the inferior nasal concha, and its place of spiraling in the nasal cavity is observed to have an important role in creating vorticesÖğe Evaluation of the Relationship between Cancer and Antioxidants from an Altmetric Perspective(2022) Guney, Turkan; Dokur, Mehmet; Vardar, Gökay; Hanikoğlu, Ferhat; Karadağ, MehmetObjectives: Antioxidants have been shown in research to have significant effects on serious diseases, particularly cancer. The goal of our experiment was to determine and analyzed 100 articles with the highest Altmetric attention scores (AAS) concerning antioxidants and cancer. Methods: Altmetric score analyzes were obtained downloading the from the Altmetric.com website. A research output's altmetric score was calculated using an algorithm based on the weighted number of all attention it receives. Results: The Altmetric scores of the 100 articles analyzed varied from 12 to 846. Twitter (n=86) was the most mentioned social media network in the articles. According to the research categories of the T100 articles in our analysis, the majority were published in "Medical and Health Science''. In terms of Twitter geographical breakdown, the United States leads among other nations, followed by the United Kingdom. According to Twitter demographics, the most of tweets on antioxidants and cancer were shared by members of the public. Conclusion: In science and research, social media is advocated as an alternative to traditional power structures and our findings could provide a preliminary look at the social, clinical, and academic impact of antioxidant and cancer research.Öğe Media-Based Clinical Research On Selfie-Related İnjuries And Deaths(Ulusal Travma ve Acil Cerrahi Derneği, 2018) Petekkaya, Emine; Dokur, Mehmet; Karadağ, MehmetAMAÇ: Yoğun olarak özçekim ve bunları sosyal medyada paylaşmak ya da bununla ilişkili davranışlar, özellikle gençler arasında giderek artmaktadır. Bu durum özçekim nedenli travmalara yol açabilir. Bu klinik çalışmayı, özçekim ilişkili yaralanma ve ölümlere dikkat çekmek için gerçekleştirdik. GEREÇ VE YÖNTEM: Çalışmamızda medya kaynaklarında rapor edilen 111 özçekim olayı veya kazası ile ilişkili 159 olgu değerlendirildi. Özçekimle ilişkili yaralanma ve ölümlerin nedenleri ile birlikte kurbanların vital bulguları, demografileri, ritmisiteleri, tercihler, olay veya kaza tipleri, risk faktörleri ve etkilenen vücut bölgeleri değerlendirildi. BULGULAR: Özçekim kurbanlarının birçoğunun öğrenci olduğu belirlendi. Özçekim ilişkili yaralanma ve ölümler en sık Hindistan, ABD ve Rusya'dan bildirilmişti. Kurbanların en sık poz tercihi uçurum kenarı idi. En sık rapor edilen kaza tipi yüksekten zemine düşme idi. Özçekim ilişkili yaralanma ve ölümlerde en sık etkilenen çoklu vücut bölgesi idi. En sık saptanan ölüm nedeni multitravma ve suda boğulma idi. TARTIŞMA: Özçekim ilişkili yaralanma ve ölümler son yıllarda giderek artmaktadır. Özellikle ergenler ve genç yetişkinler tehlikeli özçekim açısından yüksek risk taşırlar. Bu nedenle özçekim ilişkili yaralanma ve ölümleri azaltmak için bilinçlendirme yapılmalıdır.
