The purpose of this qualitative study was to investigate the experiences of physical education (PE) teachers regarding online PE lessons for children with ASD during the COVID-19 pandemic. Participants in this study were 16 PE teachers who took part in one-on-one semi-structured phone interviews. Interview data were analyzed using Braun and Clarke's recipe for thematic analysis.

- The study reports the creation of taurine-incorporated hybrid nanoflowers (thNFs) that demonstrate peroxidase-mimicking and antimicrobial activities when exposed to hydrogen peroxide (HO).
- The formation of thNFs was explored for the first time using non-enzyme molecules, with factors like taurine concentration, metal ion types (Cu, Fe), and pH being systematically analyzed.
- Characterization techniques confirmed the thNFs' porous structure and transition metal ions, which enhance their effectiveness, making them potential alternatives to traditional enzymes for various applications in medicine and industry.
Article Synopsis
- The study investigates the feasibility of measuring extracellular volume (ECV) in the right ventricle (RV) of patients with congenital heart disease (CHD), noting the challenges posed by the RV's thin walls and trabeculation.
- The research included 39 CHD patients and 17 healthy controls, utilizing cardiovascular magnetic resonance T1 mapping in two orientations and introducing a new analysis tool for measuring ECV.
- Results showed that good image quality and a minimum wall thickness were crucial for accurate RV ECV assessment, with a strong correlation between traditional and novel measurement methods.
Article Synopsis
- The study investigates a new method for measuring myocardial extracellular volume fraction (ECV), which indicates diffuse myocardial fibrosis, using T1 mapping and a single gadolinium contrast bolus in patients with congenital heart disease (CHD).
- The research included both healthy controls and CHD patients, comparing the ECV results from the bolus-only approach to those from a more complex bolus-infusion method, finding a strong correlation between the two.
- The findings suggest that the bolus-only method is a feasible option for integrating ECV measurements into routine CMR imaging practices, improving the ability to assess myocardial fibrosis in a clinical setting.
Objective : To evaluate the value of neurologic and cardiologic assessment and also the frequency of iron deficiency anemia in children with Breath Holding Spells (BHS). Methods : The hospital charts of patients diagnosed with BHS between 2011 and 2013 were reviewed retrospectively. Results : A total of 165 children (90 boys, 75 girls) with BHS comprised the study group.

At present, bipolar pacing wires are used in most institutions. In case of functional failure of these wires, a unipolar mode of stimulation and sensing should be theoretically possible as a rescue procedure.
View Article and Find Full Text PDFTularemia is an infection caused by Francisella tularensis with a worldwide distribution and diverse clinical manifestations. In recent years, tularemia cases are increasing in Turkey, with a special attention to Marmara, western Blacksea and Central Anatolia regions. The aim of this study was to evaluate tularemia cases admitted to our hospital during an outbreak emerged at Central Anatolia between December 2009 and September 2010, making a point for the disease.

The aim of this study was (1) to determine the suitability of MRI-controlled PTA using the iron oxide-based contrast medium Resovist (ferucarbotran) for catheter visualization and (2) to subsequently apply this technique in a pilot study with patients with CoA.
Methods And Results: The MRI contrast-to-noise ratio and artifact behavior of Resovist-treated balloon catheters was optimized in in vitro and animal experiments (pigs).
Purpose: To evaluate resonant circuits as markers for magnetic resonance (MR) imaging-guided placement of nitinol stents.
Materials And Methods: The study was approved by the institutional animal research committee and complied with National Institutes of Health guidelines for care and use of laboratory animals. Resonant circuits similar to catheter markers used at conventional angiography were placed proximally and distally to a nitinol stent in a stent delivery system.
Background: The aims of this study were to validate MRI-derived right ventricular (RV) pressure-volume loops for assessment of RV myocardial contractility and then to apply this technique in patients with chronic RV pressure overload for assessment of myocardial contractility, ventricular pump function, and VA coupling.
Methods And Results: Flow-directed catheters were guided under MR fluoroscopy (1.5 T) into the RV for invasive pressure measurements.
