INTRODUCTION Dramatic advances in coronary revascularization techniques have been developed in recent years. Improved technologies and techniques for coronary artery surgery and percutaneous coronary intervention have allowed for treatment of coronary vessels that were previously considered inaccessible or not amenable to conventional treatment.1 In addition, pharmacologic management of chronic...

Laser Thomson scattering (LTS) is an established plasma diagnostic technique that has seen recent application to low density plasmas. It is difficult to perform LTS measurements when the scattered signal is weak as a result of low electron number density, poor optical access to the plasma, or both. Photon counting methods are often implemented in order to perform measurements in these low signa...

To study the effects of warm laser peening (WLP) on the thermal stability and mechanical properties of A356 alloy, the samples were treated by WLP using a Nd:YAG solid-state laser and temperature control device. The residual stress, micro-hardness and microstructures of samples treated by WLP were observed. The result shows that the temperature significantly affects the strengthening effect of ...

Thoracic compartment syndrome has been observed after trauma and after mediastinal and cardiac procedures; however, an adult respiratory distress syndrome (ARDS)-like presentation has not been described as a part of thoracic compartment syndrome. We describe the case of an obese patient who underwent coronary artery bypass (his third such procedure) and hiatal hernia reduction during the same o...

Copper alloys, combined with selective laser melting (SLM) technology, have attracted increasing attention in aerospace engineering, automobile, and medical fields. However, there are some difficulties in SLM forming owing to low laser absorption and excellent thermal conductivity. It is, therefore, necessary to explore a copper alloy in SLM. In this research, manufacturing feasibility and form...

Despite significant advances in revascularization techniques and medical therapy, there remains a significant population of patients who continue to have intractable angina symptoms. This review aims to define the patients with refractory angina pectoris (RAP) and to present the therapeutic options currently available for this condition. RAP itself is defined and the pharmacological treatment o...
