Çanakkale (Türkiye)’den Arachnopezizaceae familyasına katkılar
No full textFilogenetik ve morfolojik analizlere dayanarak Helotiales ordosu içerisinde konumlandırılan Arachnopezizaceae Hosoya, J.G. Han & Baral familyası noperkülat Discomycetes türleri içermektedir. Subikulum ve septat sporlar bu familyada öne çıkan önemli morfolojik karakterlerdir. Subikulum, apothecia'yı çevreleyen substratum üzerinde birbirine bağlı ağ benzeri bir yapı oluşturan çıkıntılı hifal elemanları ifade etmektedir. Bu çalışma 25 ve 28 Ocak 2025 tarihlerinde Çanakkale, Bayramiç ilçesinde yer alan Baraj gölü yakınlarında çürümekte olan Pinus brutia L. dalları üzerinde tespit edilen Arachnoscypha aranea (De Not.) Boud. ve Serçiler köyü civarında Quercus coccifera L.–Pinus brutia L.’nın çürümekte olan dalları üzerinde tespit edilen Arachnopeziza obtusipila Grelet’nın mikro ve makro karakterlerine odaklanmıştır. Makrofungus örnekleri titizlikle gerçekleştirilen saha ve laboratuvar çalışmaları neticesinde teşhis edilmiştir. Elde edilen veriler neticesinde yeni cins kaydı Arachnoscypha aranea ve yeni tür kaydı olan Arachnopeziza obtusipila’nın makro ve mikromorfolojik özellikleri tanımlanmış ve gösterilmiştir. Morfolojik karakterlere dayalı olarak tanımlanan makrofungusların daha anlaşılır ve net olması için CorelDRAW çizim programı kullanılarak mikromorfolojik özellikler çizilmiştir. Dünyada iki tür ile temsil edilen Arachnoscypha cinsinin ilk kaydı, ülkemizdeki tür sayısı iki olan Arachnopeziza cinsinin üçüncü türü bu çalışmada verilerek Türkiye mikobiotasına katkı sağlanmıştır.Based on phylogenetic and morphological analyses, the family Arachnopezizaceae Hosoya, J.G. Han & Baral, which is placed in the order Helotiales, contains non-operculate Discomycetes. Subiculum and septate spores are important morphological characters in this family. Subiculum refers to the protruding hyphal elements forming an interconnected network-like structure on the substratum surrounding the apothecia. This study focused on the micro and macro characters of Arachnoscypha aranea (De Not.) Boud. detected on decaying Pinus brutia L. branches near the dam lake in Bayramiç district, Çanakkale on 25 and 28 January 2025, and Arachnopeziza obtusipila Grelet detected on decaying branches of Quercus coccifera L.–Pinus brutia L. near Serçiler village. Macrofungal samples were identified as a result of meticulous field and laboratory studies. As a result of the data obtained, the macro- and micromorphological characteristics of the new genus record Arachnoscypha aranea and the new species record Arachnopeziza obtusipila were described and illustrated. In order to make the macrofungi described based on morphological characters clearer and more understandable, micromorphological features were drawn using CorelDRAW drawing software. The first record of the genus Arachnoscypha, which is represented by two species in the world, and the third species of the genus Arachnopeziza, which is represented by two species in our country, were given in this study, contributing to the mycobiota of Türkiye
Evaluation of coronary artery calcium score by age and sex: a multicenter study
No full textPurpose: To evaluate coronary artery calcium (CAC) scores in a large Turkish cohort using age- and sex-specific percentiles, and to assess the agreement between CAD-RADS plaque burden scores and percentile-based CAC classification. Methods: A total of 4,887 clinically referred patients who underwent coronary CT angiography (CCTA) with non-contrast imaging were retrospectively evaluated. CAC scores were calculated using the Agatston method. Percentile reference values were generated according to age, sex, and number of cardiovascular risk factors. “Coronary age” was estimated by matching each individual’s CAC score to the 50th percentile value. The agreement between CAD-RADS P scores and percentile-based classification was assessed using Cohen’s kappa. Results: Age, male sex, and traditional risk factors (hypertension, diabetes, hyperlipidemia, and smoking) were significantly associated with higher CAC scores (p 0 increased with each additional risk factor. Among individuals with low to intermediate cardiovascular risk, 22.3% had CAC scores above the 75th percentile. ROC analysis showed strong discriminatory ability for risk factor-based prediction of CAC > 0 (AUC = 0.873). However, agreement between CAD-RADS P scores and percentile-based classification was poor (κ = 0.12, p < 0.01). Conclusion: Absolute CAC scores do not reliably reflect relative risk in younger or low-risk individuals. Percentile-based interpretation and coronary age estimation offer a more individualized approach, particularly valuable in low-to-intermediate risk populations
