Nonlinear Optical Properties of CsAgInBiCl Single Crystals.

Lead-free double perovskites offer enhanced stability and lower toxicity compared to their lead-based counterparts. Dual B-site cations can introduce elemental and structural diversity into double perovskite materials, enabling fine-tuning of the optical properties. However, the study of the nonlinear optical (NLO) properties of lead-free double perovskites is still nascent, hindering their relevant potential applications.

Strong two-photon absorption induced by energy funneling in chiral quasi-2D perovskites.

Quasi-2D Ruddlesden-Popper-type perovskites (RPPs) exhibit excellent nonlinear optical properties due to their multiple quantum well structures with large exciton binding energy. Herein, we introduce chiral organic molecules into RPPs and investigate their optical properties. It is found that the chiral RPPs possess effective circular dichroism in the ultraviolet to visible wavelengths.

High Platelet Count is a Potential Prognostic Factor of the Early Recurrence of Hepatocellular Carcinoma in the Presence of Circulating Tumor Cells.

Purpose: Recent studies indicated the vital role of platelet in enhancing the survival of circulating tumor cells (CTCs) in the blood, thereby stimulating the metastasis of tumors. CTCs have been considered an indicator of early tumor recurrence. Therefore, this study evaluated the prognostic potential of platelet count in predicting the early recurrence of hepatocellular carcinoma (HCC) in the presence of CTCs.

Ideal Cardiovascular Health Metrics and Coronary Artery Calcification in Northern Chinese Population: A Cross-sectional Study.

Objective: Coronary artery calcification (CAC) is a well-established risk predictor of coronary heart disease events and is recognized as an indicator of subclinical atherosclerosis.

Methods: A cross-sectional study consisting of 2999 participants aged ⋝40 years from the Jidong community of Tangshan City, an industrial and modern city of China, was conducted between 2013 and 2014 to examine the association between the ideal cardiovascular health (CVH) metrics and CAC. The ideal CVH metrics were determined based on the definition of the American Heart Association (AHA).
