Dynamic responsiveness of self‐assembling peptide‐based nano‐drug systems
Interdisciplinary Medicine, Volume 1, Issue 1, January 2023., 2023 This review discusses dynamically responsive self‐assembling peptide‐based nano‐drug systems, including the stimulation response, strategy of biomimicry, subcellular internalization, and the applications of peptide nano‐drug materials, and concludes with a brief outlook of their challenges and opportunities in clinical translation.

Low‐field MRI: Clinical promise and challenges
Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023 Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.

CSDN: Combing Shallow and Deep Networks for Accurate Real-time Segmentation of High-definition Intravascular Ultrasound Images [PDF]
arXiv, 2023 Intravascular ultrasound (IVUS) is the preferred modality for capturing real-time and high resolution cross-sectional images of the coronary arteries, and evaluating the stenosis. Accurate and real-time segmentation of IVUS images involves the delineation of lumen and external elastic membrane borders.

Common femoral artery erosion as a source of thromboembolic acute limb ischemia
Journal of Vascular Surgery Cases and Innovative Techniques, 2021 We have reported a case of delayed hip prosthetic erosion into the common femoral artery (CFA) 3 years after implantation. The patient had initially presented with left lower extremity acute limb ischemia secondary to a popliteal artery embolism. However,

Segmentation of Anatomical Layers and Artifacts in Intravascular Polarization Sensitive Optical Coherence Tomography Using Attending Physician and Boundary Cardinality Losses [PDF]
arXiv, 2021 Intravascular ultrasound and optical coherence tomography are widely available for characterizing coronary stenoses and provide critical vessel parameters to optimize percutaneous intervention. Intravascular polarization-sensitive optical coherence tomography (PS-OCT) simultaneously provides high-resolution cross-sectional images of vascular structures

The Kaohsiung Journal of Medical Sciences, Volume 38, Issue 12, Page 1203-1212, December 2022., 2022 Abstract The role of the calcium‐sensitive receptor (CaSR) was assessed in a juvenile mouse model of asthma induced by ovalbumin (OVA). The experiment was divided into normal control, OVA, and OVA +2.5/5 mg/kg NPS2143 (a CaSR antagonist) groups.
