Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

open access: yesAdvanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

One year in review: ultrasound in arthritis [PDF]

open access: yes, 2016
Musculoskeletal ultrasound (MSUS) has become a relevant part of rheumatology practice and research because it substantially allows us to optimize management of rheumatic and musculoskeletal diseases. This non-invasive imaging modality is a valuable point-

Macrophage‐targeted cerium‐tannic acid metal‐polyphenol framework nanoenzyme promotes in situ heart valves regeneration through adaptive immunomodulation

open access: yesBMEMat, EarlyView.
A novel nanoenzyme based on cerium ions‐tannic acid metal‐polyphenol framework (FCT) has been developed and loaded onto DHVs for targeting M1 macrophages to reduce their ROS level and reprogram macrophage phenotype, thereby eliminating inflammation, promoting endothelialization and adaptive matrix remodeling of scaffolds, offering a promising strategy ...

Radial capacity and hemodynamics evaluation in vitro and implantable feasibility validation in vivo of thinner bioresorbable polymer vascular stents

open access: yesBMEMat, EarlyView.
A series of in vitro experiments, numerical simulations and in vivo experiments were conducted to jointly evaluate the effects of different thicknesses of bioabsorbable polymer vascular stents on their radial capacity, hemodynamics and in vivo outcomes.

Flap perfusion of superficial split flap design for guided bone regeneration: A case report with ultrasonography

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Effective flap management is crucial for successful bone regeneration procedures. Traditional flap release has been performed by the deep split design; recently, the superficial split design revives for its proposed anatomical and biomechanical advantages.

Fibrin sheath of a peripherally inserted central catheter undepicted with gray-scale (real-time B-mode) ultrasonography: A case report

open access: yesRadiology Case Reports, 2018
An 11-year-old male was admitted to our hospital with the acute exacerbation of chronic heart failure. A peripherally inserted central catheter (PICC) was inserted from the left forearm.

Transcatheter Repair of Sinus Venosus Defect Using a 12‐zig Covered Cheatham‐Platinum Stent in Large Superior Vena Cava—Right Atrium Junctions: Early Multicenter Experience

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Sinus venosus defect (SVD) is a rare congenital heart anomaly characterised by an abnormal communication between the atria, often associated with partial anomalous pulmonary venous connection (PAPVC). Traditional surgical repair carries significant risks, prompting exploration into less invasive transcatheter approaches.

Analysis of tissue surrounding thyroid nodules by ultrasound digital images [PDF]

open access: yes, 2015
Since US is not easily reproducible, the digital image analysis (IA) has been proposed so that the image evaluation is not subjective. In fact, IA meets the criteria of objectivity, accurateness, and reproducibility by a matrix of pixels whose value is ...

Prevalence of transthyretin cardiac amyloidosis in undifferentiated heart failure with preserved ejection fraction

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1176-1182, April 2025.
Abstract Aims Transthyretin amyloid cardiomyopathy (ATTR‐CM) is an increasinglyrecognized cause of heart failure with preserved ejection fraction (HFpEF), which may be diagnosed non‐invasively using 99mTc 3,3‐diphosphono‐1,2‐propanodicarboxylic acid (DPD) scintigraphy‐based diagnostic criteria.
