Article Synopsis
- Anisotropic metasurfaces allow for independent control of electromagnetic waves with different polarizations, providing new options for communication and imaging systems.
- The proposed dual-polarization modulation metasurface (DPMM) operates in the terahertz frequency range and can effectively modulate two orthogonally polarized waves using an anisotropic structure combined with GaN-based transistors.
- Simulation and experiments show that the DPMM achieves high modulation isolation (over 45 dB) and impressive speeds (over 2 GHz for dual polarization), making it a strong candidate for improving data capacity and throughput in THz technologies.
Article Synopsis
- The Inflammatory Burden Index (IBI) is a new indicator that shows the relationship between inflammation and various diseases, particularly coronary slow flow phenomenon (CSFP) in patients with chest pain but no obstructive coronary artery disease.
- In a study with 1,126 participants, it was found that IBI levels were significantly higher in patients with CSFP compared to those with normal blood flow, with IBI independently predicting CSFP alongside body mass index (BMI).
- The study concluded that IBI is a valuable tool for predicting CSFP, as it improves diagnostic accuracy with a specificity of 67.6% and sensitivity of 77.5% when levels exceed 15.74.
BACKGROUND Recently, the albumin-to-creatinine ratio (ACR) has been suggested as a valuable biomarker for adverse events in acute myocardial infarction. However, the prognostic value of ACR in very elderly patients (≥80 years) with non-ST-elevation acute coronary syndrome (NSTE-ACS) after percutaneous coronary intervention (PCI) remains unclear. MATERIAL AND METHODS A total of 354 very elderly patients with NSTE-ACS who underwent PCI were included in this study and followed up for 1 year.

- Inflammation is a major factor in slow coronary flow phenomenon (SCFP), which complicates cases of ischemia in patients with no obstructive coronary arteries (INOCA). Identifying reliable predictors of SCFP is essential for better management of these patients.* -
- In a study involving 1422 INOCA patients, those with SCFP exhibited higher systemic inflammation response index (SIRI) levels compared to controls, along with increased body mass index (BMI), smoking, and diabetes rates.* -
- Results indicated that BMI and SIRI are independent predictors of SCFP, with SIRI showing promise as a useful tool for distinguishing SCFP, especially when its value exceeds 1.140, indicating a significant predictive sensitivity
Background: Accumulating evidences suggest that low-grade inflammatory response plays a key role in the pathophysiology of coronary slow flow phenomenon (CSFP). As a new hematological inflammatory indicator, the neutrophil percentage to albumin ratio (NPAR) and its role in the occurrence and development of CSFP remains unclear. In this study, we aimed to investigate the predictive value of NPAR in the presence of CSFP in patients with myocardial ischemia and no obstructive coronary arteries (INOCA).
