Platelet-To-Lymphocyte Ratio as a Predictor of No-Reflow after Primary Percutaneous Coronary Intervention in Patients with ST Elevation Myocardial Infarction: A Systematic Review and Meta-Analysis [PDF]

Journal of Cardio-Thoracic Medicine, 2019
Introduction: No-reflow increases the complications and mortality rate of primary percutaneous coronary intervention (PCI). Therefore, it is important to identify patients at a higher risk of developing no-reflow.

The Effect Of Void Formation On The Reliability Of ED-XRF Measurements In Lead-Free Reflow Soldering

Archives of Metallurgy and Materials, 2015
In lead-free reflow soldering, the presence of voids should be taken into account. For this reason, the effect of the applied heating profiles was examined via the characterization of voids in galvanic and immersion Sn coatings. According to EU Directive
