Waste polyethylene (WPE) and virgin polyethylene (VPE) (50:50) thermoplastic have been melt-mixed with biochar (BC) made from orange peels at ratios of 5, 10, and 15(Phr) to evaluate how the filler content affected the mechanical, thermal, optical, electrical conductivity, and electromagnetic interference (EMI). γ-rays was applied to the prepared specimens to assess how radiation affected the created biocomposites. From the obtained results, the combination of BC with γ-rays, at doses of up to 100 kGy, with thermoplastic resulted in an enhanced mechanical property, particularly for composites containing 15 Phr of BC added because of its unique structure and excellent dispersion.

This study evaluates the utility of RWMA on TTE for detecting obstructive CAD in patients with no prior CAD history.
Methods: We retrospectively reviewed charts of adults who underwent resting TTE and coronary angiography within 30 days, analyzing RWMA in relation to angiographic luminal stenosis.
Article Synopsis
- - Primary pulmonary artery sarcoma is a rare cancer that is often misdiagnosed as a pulmonary embolism (PE) due to similar symptoms and imaging results, leading to poor treatment outcomes and a lack of clear guidelines.
- - A case of a 39-year-old woman with a history of miscarriages presented with difficulty breathing and was initially thought to have a PE, but later surgery revealed a high-grade sarcoma in her pulmonary artery.
- - This case highlights the challenges in accurately diagnosing pulmonary artery sarcomas, emphasizing the need for careful evaluation to avoid mismanagement in patients presenting with respiratory issues.
Article Synopsis
- - Cocaine use can lead to serious heart conditions such as heart attacks and cardiomyopathy, posing significant health risks and burdens on healthcare systems.
- - Cardiac magnetic resonance (CMR) imaging is essential for identifying and assessing heart damage, allowing for the differentiation between acute and chronic injuries linked to cocaine use.
- - Early detection through CMR can help reverse damage caused by cocaine, making it a crucial tool for better management of cocaine-related heart issues.
Objectives: Although coronary artery disease (CAD) and heart failure (HF) are separate entities, HF is a common complication of CAD, and both CAD and HF are known causes of wall motion abnormalities (WMA) of transthoracic echocardiography (TTE). Specifically, global hypokinesis on TTE could logically be due to multivessel CAD or non-ischemic cardiomyopathy. The purpose of this study was to investigate the relationship between CAD, HF, and WMA on TTE.
