Ermenek Vadisi (Karaman, Mersin-Türkiye)’nin Briyofit Florası

In this study, the bryophyte flora of Ermenek Valley (Karaman, Mersin) was investigated. In a total 163 taxa belonging to 27 families and 64 genera were determined by identifying the bryophyte specimens collected from 33 stations at different habitats and different vegetation periods between the years 2019 and 2020. Marchantiophyta, 10 taxa belonging to 8 families and 10 genera, Bryophyta, 153 taxa belonging to 19 families and 54 genera are represented. Among them, 39 taxa are new records for C12 grid square and, also Fissidens gymnandrus is recorded for the second time from Turkey.

The relationship between functional capacity and ultrasonic tissue characterization in patients with idiopathic dilated cardiomyopathy

Background: Ultrasonic tissue characterization (UTC) has been widely used to investigate left ventricular (LV) dysfunction in various cardiac disorders. The aim of this study was to investigate the correlation between functional capacity and UTC in patients with idiopathic dilated cardiomyopathy (IDCM).Methods and Results: Treadmill test according to modified-Bruce protocol was performed in 48 patients with IDCM to assess their functional capacity. Baseline clinical and echocardiographic variables were obtained and UTC was performed on images obtained from septum and posterior wall (PW). Cyclic variation (CV) index of mean gray level (MGL) was calculated according to the formula: [(MGLdiastole − MGLsystole) ÷ MGLdiastole] × 100.PW and septum CV indices were correlated with exercise duration (r = 0.63, p = 0.001 and r = 0.67, p = 0.0001, respectively) and “MET” level (r = 0.80, p = 0.0001 and r = 0.83,p = 0.0001, respectively). The ROC curve analysis revealed that the PW CV index was a strong indicator of good exercise capacity (> 8 METs) with an AUC of 0.97 (95% CI0.90–1.0), as the interventricular septum (IVS) CV index (AUC = 0.97, 95% CI 0.89–1.0). Sensitivity, specificity, positive predictive value, and negative predictive value to identify good exercise capacity for IVS CV index were 90%, 88%, 82%, and 94%, respectively and for the PW CV index, 90%, 88%, 82%, and 94%, respectively.Conclusions: In this particular study, we found out that in patients with severe LV dysfunction good exercise capacity was related to septum and PW CV indices measured by UTC, and these indices may be used as an indirect prognostic marker in heart failure

Hemiplejik serebral palsili çocukların üst ekstremitelerinin sağlam tarafı da gelişim geriliği gösterir

Amaç: Çalışmamızda çocuklarda hemiplejik serebral palsi’nin HSP neden olduğu üst ekstremite gelişim geriliğinin antropometrik yöntemlerle incelenmesi amaçlandı. Gereç ve yöntem: Çalışmamızda Etik Kurul onayı alınarak 5-12 yaşlarındaki 32 HSP’li çocuk ile 40 normal çocuğun üst ekstremiteleri antropometrik set ile ölçülerek karşılaştırıldı. Bulgular: HSP’li çocukların sağlam taraf omuz eklemi, kol, dirsek eklemi, ön kol ve el bilek eklemi çevresi; üst ekstremite, kol, ön kol, el ve el ayası uzunluğu; dirsek eklemi, el bilek eklemi ve el genişliği değerleri HSP’li çocukların plejik tarafına göre anlamlı derecede fazlaydı. Normal çocukların omuz eklemi, kol, dirsek eklemi, ön kol ve el bilek eklemi çevresi; üst ekstremite, kol, ön kol, el ve el ayası uzunluğu; dirsek eklemi, el bilek eklemi ve el genişliği değerleri HSP’li çocukların plejik taraf ölçümlerine göre anlamlı derecede yüksekti. Normal çocukların dirsek eklemi ve ön kol çevresi; el ve el ayası uzunluğu; dirsek eklemi, el bilek eklemi ve el metakarpallerden genişliği değerleri HSP’li çocukların sağlam tarafına göre anlamlı derecede yüksekti. Sonuç: Antropometrik ölçümler HSP’li çocukların plejik taraf üst ekstremitelerinin sağlam tarafa göre, normal çocuklarla karşılaştırdığımızda ise hem plejik hem de sağlam taraflarının daha az geliştiğini göstermektedir. HSP’li çocukların az gelişmiş plejik taraflarını kullanamamaları günlük yaşam aktivitelerini de kısıtlayarak sağlam tarafta da kas ve kemik gelişim geriliğine sebep olmaktadır. Erken teşhis ve rehabilitasyon ile bu fark azaltılabili

A simplified acute kidney injury predictor following transcatheter aortic valve implantation: ACEF score

Background: Transcatheter aortic valve implantation (TAVI) is an effective, less invasive treatment alternative for symptomatic severe aortic stenosis (AS). Acute kidney injury (AKI) following TAVI is a common complication and is associated with worse outcomes. The age, creatinine, ejection fraction (ACEF) score is a simple scoring method, including only three parameters: age, creatinine, and ejection fraction (EF). The score was well established in predicting AKI after coronary interventions.Aims: We aimed to evaluate whether this simple scoring method, ACEF, may predict a development of AKI in patients who underwent TAVI.Methods: A total of 173 consecutive patients with symptomatic severe AS who underwent TAVI were included retrospectively. The primary endpoint of the study was the development of AKI. Study population was divided into two groups according to the presence of AKI. The ACEF score was calculated with the formula: age/EF + 1 (if baseline creatinine >2 mg/dl).Results: Twenty-nine patients developed AKI. The median (interquartile range) ACEF score was 1.36 (1.20–1.58). The ACEF score was found to be an independent predictor of AKI (P <0.001). The ACEF score ≥1.36 predicted AKI development with a sensitivity of 96.6% and specificity of 58.8%. Moreover, hypertension, hemoglobin levels, contrast volume, and aortic valve area (AVA) were found to be independent predictors of AKI.Conclusions: Our study revealed that the ACEF score was an independent predictor of AKI. A simple and objective score might be very useful in predicting AKI development in patients undergoing TAVI

A COMPLETE METHODOLOGY FOR THE COMPUTATION OF EXTERNAL HEAT FLUXES FOR THE TRANSIENT THERMAL ANALYSIS OF SATELLITES

This paper describes a complete methodology for the computation of transient external heat fluxes (i.e. solar, albedo and earth) for a given set of orbital parameters such as altitude, solar constant etc. and orientation of the satellite. A software module based on this methodology was developed and its performance was assessed by comparing its predictions with the ones obtained by a commercial software on the same test problem. Comparisons revealed that the external fluxes can be computed accurately with the developed module. It was then used in conjunction with an in-house thermal analysis code based on Thermal Network Method (TNM) and Monte Carlo Ray Tracing Technique (MCRT) for the transient simulation of the same test problem. It was shown that the temperature predictions obtained by the in-house code and the commercial software were in excellent agreement with each other and the developed software is a reliable, accurate and complete tool that can be used in the thermal analysis of satellites
