AI Article Synopsis
- Dispersing hydrophobin HFBII using perfluorohexane gas prevents aggregation, keeping sizes at the nanometer level.
- The presence of fluorocarbon gas leads to a unique co-adsorption effect, significantly enhancing HFBII adsorption at the air/water interface.
- This method results in uniform spherical microbubbles that are stable and echogenic, with altered film characteristics that prevent solid phase transition.
Article Abstract
Dispersing hydrophobin HFBII under air saturated with perfluorohexane gas limits HFBII aggregation to nanometer-sizes. Critical basic findings include an unusual co-adsorption effect caused by the fluorocarbon gas, a strong acceleration of HFBII adsorption at the air/water interface, the incorporation of perfluorohexane into the interfacial film, the suppression of the fluid-to-solid 2D phase transition exhibited by HFBII monolayers under air, and a drastic change in film elasticity of both Gibbs and Langmuir films. As a result, perfluorohexane allows the formation of homogenous populations of spherical, narrowly dispersed, exceptionally stable, and echogenic microbubbles.

Article Synopsis
- Acute appendicitis and acute cholecystitis often occur together, and surgical management is effective for both conditions when they present simultaneously.
- A 30-year-old female patient presented with abdominal pain and underwent imaging that confirmed the diagnoses, leading to a successful surgical intervention combining cholecystectomy and appendectomy.
- The case underscores the importance of recognizing the possibility of both conditions occurring together and utilizing established management guidelines for effective treatment.
Ultrasonically Determined Thyroid Volume in Individuals with Bipolar Disorder on Lithium Prophylaxis Compared with Healthy Controls.

Introduction: Lithium is a gold-standard agent for bipolar disorder (BD) and can affect the size, structure and/or function of thyroid gland with long-term exposure. Thyroid ultrasound can detect structural thyroid abnormalities, but it is under-reported with few prior studies in lithium users. The study aimed to evaluate thyroid volume and echogenicity in lithium users with BD and healthy participants, and explores its association with clinical variables and thyroid functions.

A 54-year-old patient with a medical history of hypertension, dyslipidemia, and diabetes underwent mitral valve replacement surgery with a biologic valve. During a chest computed tomography scan for breast neoplasia staging, a reduced luminal filling in the left atrium (3.6 cm) was unexpectedly found, prompting further cardiac evaluation.

Objectives: Muscle MRI and ultrasound provide complementary techniques for characterizing muscle changes and tracking disease progression in facioscapulohumeral muscular dystrophy (FSHD). In this cohort study, we provide longitudinal data that compares both imaging modalities head-to-head.
Methods: FSHD patients were assessed at baseline and after five years.
Proteomic analysis of the extracellular matrix of human atherosclerotic plaques shows marked changes between plaque types.

Cardiovascular disease is the leading cause of death, with atherosclerosis the major underlying cause. While often asymptomatic for decades, atherosclerotic plaque destabilization and rupture can arise suddenly and cause acute arterial occlusion or peripheral embolization resulting in myocardial infarction, stroke and lower limb ischaemia. As extracellular matrix (ECM) remodelling is associated with plaque instability, we hypothesized that the ECM composition would differ between plaques.
