Pharmacokinetics and fate of free and encapsulated IRD800CW-labelled human BChE intravenously administered in mice.

Human butyrylcholinesterase (BChE) is an efficient bioscavenger of toxicants. Highly purified BChE was labelled with the near infrared fluorescent IRDye800CW. The goal was to determine the pharmacokinetics and fate of enzyme in mice.

Continuous transcranial ultrasound in large vessel stroke: Image guidance for high-intensity focused sonothrombolysis.

Background And Purpose: Sonothrombolysis is a potential adjunctive therapy for large vessel occlusion (LVO) stroke. Bedside ultrasound image-guided high-intensity focused ultrasound (HIFU) therapy could deliver higher energy therapeutic ultrasound to the thrombus with higher precision than what was previously accomplished in human trials. The aim is to test the feasibility of diagnostic transcranial contrast-enhanced ultrasound (CEUS) to image the occlusion site and continuously maintain the guidance image on-target for a sufficient exposure time for HIFU to be effective during LVO stroke evaluation and treatment.

Improving Cardiovascular Disease Primary Prevention Treatment Thresholds in a New England Health Care System.

Background: Atherosclerotic cardiovascular disease (ASCVD) risk estimation based on the pooled cohort equation (PCE) overestimates in population-based cohorts. Whether it performs equally across disaggregated demographics in health care populations is less known.

Objectives: The purpose of the study was to recalibrate PCE and rederive prevention thresholds in a contemporary health care system and evaluate its performance across sociodemographics.

Embedded real-time ultrasound-based multi-touch system.

In this paper, an active ultrasound-based touchscreen technology is presented for real-time monitoring of multiple contacts on a glass panel of 20 × 19 cm. Both fundamental Lamb wave modes are generated by sending a linear chirp between 50 and 100 kHz to a single piezoelectric ceramic lead zirconate titanate. Measurement is performed using four piezoelectric ceramic lead zirconate titanate elements, and real-time localization and detection are performed on a system on module i.

Association of positive airway pressure termination with mortality and non-fatal cardiovascular events in patients with obstructive sleep apnoea.

Background And Aims: The recurrence of obstructive sleep apnoea (OSA) after positive airway pressure (PAP) therapy termination has physiological consequences that may increase cardiovascular (CV) risk. We aimed to determine whether PAP termination is associated with an increased incidence of major adverse CV events (MACE) compared with adherent PAP continuation.

Methods: Data from the Pays de la Loire Sleep Cohort were linked to the French national health insurance database to identify incident MACE (composite outcome of mortality, stroke and cardiac diseases), and CV active drug (lipid-lowering, antihypertensive and antiplatelet drugs, beta-blockers) adherence (medication possession ratio ≥80%).
