Background: Aortic/arterial stiffness is a reliable, independent predictor and a risk factor for cardiovascular mortality. Arterial stiffness is assessed by pulse wave velocity and echocardiography. The purpose of this study is to analyse aortic/arterial stiffness in patients using echocardiographic and pulse wave velocity techniques.
Materials And Methods: The participants of this study consisted of 62 patients who presented to the Gazi University Pediatric Endocrinology and Pediatric Cardiology outpatient clinics, including 21 obese, 20 overweight, and 21 normal-weight patients. Echocardiography was performed on all patients, and echocardiographic measurements were compared to pulse wave velocity measurements.
Results: The mean (min-max) arterial strain measurements were 0.146 ± 0.0 (0.06-0.3) in the obese group and 0.106 ± 0.0 (0.05-0.18) in the overweight group. In comparison to the overweight group, the obese group had greater arterial strain measurements. The pulse wave velocity measurements in the obese and overweight groups were greater than those in the normal weight group (p > 0.05). Elastic modulus and aortic stiffness ß index values were shown to be positively correlated with pulse wave velocity measurements in the obese group (r = 0.56, r = 0.53, respectively; p = 0.008, p = 0.01, respectively). Systolic and diastolic blood pressure measurements were correlated with pulse wave velocity measurements in the obese group (r = 0.98, p = 0.0001, respectively).
Conclusion: In our study, echocardiographic aortic measurements showing the vessel wall were correlated with pulse wave velocity measurements. Echocardiographic evaluation should be included in the routine follow-up of patients because pulse wave velocity measurement devices are not available in all centres, echocardiography is available in many centres, it is easily applicable, and it facilitates the follow-up of patients.

Extracorporeal shock wave therapy (ESWT) achieves its therapeutic purpose mainly through the biological effects produced by the interaction of shock waves with tissues, and the accurate measurement and calculation of the mechanical parameters of shock waves in tissues are of great significance in formulating the therapeutic strategy and evaluating the therapeutic effect. This study utilizes the approach of implanting flexible polyvinylidene fluoride (PVDF) vibration sensors inside the tissue-mimicking phantom of various thicknesses to capture waveforms at different depths during the impact process in real time. Parameters including positive and negative pressure changes (P, P), pulse wave rise time ([Formula: see text]), and energy flux density (EFD) are calculated, and frequency spectrum analysis of the waveforms is conducted.

Controlled synthesis of faceted nanoparticles on surfaces without explicit use of ligands has gained attention due to their promising applications in electrocatalysis and chemical sensing. Electrodeposition is a desirable method; however, precise control over their size, spatial distribution, and morphology requires extensive optimization. Here, we report the spatially resolved synthesis of shape-controlled Pt nanoparticles and fast screening of synthesis conditions in scanning electrochemical cell microscopy (SECCM) with pulse potentials.

Background: Superior caval vein obstruction is a rare complication of endocardial pacing lead implantation that can result in a right to left shunt.
Case Summary: A 3-year-old child with type 2 Brugada syndrome presented with mild cyanosis post-endocardial pacing implantation due to evolutionary right superior caval vein obstruction. This obstruction resulted in a right to left shunt across a previously unrecognized patent levo-atrial cardinal vein associated with partial anomalous pulmonary venous drainage.

This study evaluates the effects of different high-intensity focused ultrasound irradiation (HIFU) methods on local tumor suppression and systemic antitumor effects, including the abscopal effect, in a mouse model of pancreatic cancer. To ascertain the efficacy of the treatment, pancreatic cancer cells were injected into the thighs of mice and HIFU was applied on one side using continuous waves or trigger pulse waves. Then, tumor volume, tissue changes, and immune marker levels were analyzed.
