A feasibility study is presented on the experimental application of ultrasound to examine rolled stainless steel plates having equidistant surface textures in two directions in the form of Penrose tiles. The specific problem of interest is investigating surface profile quality in terms of its equidistance and depth to monitor the manufacturing process. The goal is to eventually replace current time-consuming optical examination procedures with a reliable and rapid ultrasonic inspection technique. Two practical experimental setups are discussed and compared in this work: examining frequency spectra obtained from normal incidence pulse-echo measurements, and those obtained at Laue angle incidence. A thorough survey of ultrasonic methods precedes the experimental results to investigate such surfaces from a historical perspective.

Introduction: Laparoscopic distal pancreatectomy (LDP) has the advantages of reduced blood loss, shorter hospital stays, and a better postoperative quality of life compared with open distal pancreatectomy (ODP). Meanwhile, spleen-preserving laparoscopic distal pancreatectomy is the preferred technique for low-grade malignant and benign tumors located in pancreatic body and tail, since it preserves the immune function of the spleen. The splenic-vessel-preserving (SVP) Kimura technique and splenic vessel resection Warshaw technique are the two primary procedures.

Immunogenic cell death (ICD) offers a promising avenue for the treatment of triple-negative breast cancer (TNBC). However, optimizing immune responses remains a formidable challenge. This study presents the design of RBCm@Pt-CoNi layered double hydroxide (RmPLH), an innovative sonosensitizer for sonodynamic therapy (SDT), aimed at enhancing the efficacy of programmed cell death protein 1 (PD-1) inhibitors by inducing robust ICD responses.

Background: Abdominal aortic calcification (AAC) is considered as a strong predictor of cardiovascular disease (CVD) events. Our study aimed to investigate whether the predicted risk for cardiac death with the Framingham risk score (FRS) could be further improved with the addition of AAC score in general population aged ≥ 40 years.
Methods: A total of 2971 participants aged ≥ 40 years in the National Health and Nutrition Examination Surveys (NHANES) 2013-2014 were followed up.

Introduction: Acoustic shadowing is an important benign ultrasound (US) feature for adnexal masses (AMs). To validate the diagnostic performance and interobserver agreement of the 2019 version and 2022 version of Ovarian-Adnexal Reporting and Data System Ultrasound (O-RADS US) and ascertain whether adding acoustic shadowing to O-RADS US v2019 as a benign ultrasound feature can enhance its diagnostic efficacy among junior radiologist.
Methods: This retrospective study included consecutive women with suspected adnexal masses who underwent ultrasound examinations between September 2022 and January 2024.

Background: The arterial stiffening is attributed to the intrinsic structural stiffening and/or load-dependent stiffening by increased blood pressure (BP). The respective lifetime alterations and major determinants of the two components with normal aging are not clear.
Methods: A total of 3053 healthy adults (1922 women) aged 18-79 years were enrolled.
