Pad printing is used in automotive, medical, electrical and other industries, employing diverse materials to transfer a 2D image onto a 3D object with different sizes and geometries. This work presents a universal fixation system for pad printing of plastic parts (UFSP4) in response to the needs of small companies that cannot afford to invest in the latest technological advances. The UFSP4 comprises two main subsystems: a mechanical support system (i.

We aimed to study the effect of sonothrombolysis on the myocardial dynamics and infarct size obtained by real-time myocardial perfusion echocardiography and their value in preventing left ventricular remodeling.
Methods: One hundred patients with ST-segment-elevation myocardial infarction were randomized to therapy (50 patients treated with sonothrombolysis and percutaneous coronary intervention) or control (50 patients treated with percutaneous coronary intervention only).
Article Synopsis
- Preclinical studies indicate that high mechanical index (MI) ultrasound impulses can enhance blood flow during treatment for ST-segment elevation myocardial infarction (STEMI).
- A clinical trial involving 100 patients tested sonothrombolysis combined with standard percutaneous coronary intervention (PCI) against PCI alone to evaluate its effects on heart function and recovery.
- Results showed that patients receiving sonothrombolysis had significantly better outcomes in terms of heart function improvement, reduced infarct size, and higher rates of blood flow restoration compared to those who only underwent PCI.
Background: Heart failure is a highly prevalent disease, the prognosis of which depends on different predictive factors.
Objective: Chagas disease is a predictor of poor prognosis in patients with chronic heart failure (HF). The purpose of this study is to investigate whether this condition also predicts poor outcome in acutely decompensated patients.
Objective: Amiodarone has been shown to be superior to both placebo and lidocaine in improving survival to hospital admission for victims of out-of-hospital refractory ventricular fibrillation. Concern had been expressed about the known vasodilatatory effects of amiodarone if given without precedent vasoconstrictive medications. The haemodynamic effects of intravenous amiodarone administered during ongoing CPR have not been systemically investigated.
