Embosphere microspheres size for bronchial artery embolization in patients with hemoptysis caused by bronchiectasis: a retrospective comparative analysis of 500-750 versus 700-900 μm microspheres.

Background: Bronchial arterial embolization (BAE) has been accepted as an effective treatment for bronchiectasis-related hemoptysis. However, rare clinical trials compare different sizes of specific embolic agents. This study aims to evaluate whether different Embosphere microsphere sizes change the outcome of BAE.

Transarterial embolization/chemoembolization therapy for hepatocellular carcinoma fed by adrenal artery: Preliminary results.

To assess the value of transarterial embolization/chemoembolization (TAE/TACE) therapy via adrenal artery for patients with hepatocellular carcinoma (HCC). Patients with HCC who underwent TAE/TACE therapy via adrenal artery between May 2003 and October 2015 across 4 medical centers were identified. Clinical information, procedural data, and imaging data were analyzed to assess technical success, disease control, and survival rates.

Dispersive liquid-liquid microextraction for the determination of phenols by acetonitrile stacking coupled with sweeping-micellar electrokinetic chromatography with large-volume injection.

The current routes to couple dispersive liquid-liquid microextraction (DLLME) with capillary electrophoresis (CE) are evaporation of water immiscible extractants and backextraction of analytes. The former is not applicable to extractants with high boiling points, the latter being effective only for acidic or basic analytes, both of which limit the further application of DLLME-CE. In this study, with 1-octanol as a model DLLME extractant and six phenols as model analytes, a novel method based on acetonitrile stacking and sweeping is proposed to accomplish large-volume injection of 1-octanol diluted with a solvent-saline mixture before micellar electrokinetic chromatography.
