Microfluidics is an emerging technology for buffer exchange in bioprocessing applications. However, achieving buffer exchange with simplicity of operation and high throughput in a straightforward channel design remains a challenge. This study presents a novel semicircular microchannel design that allows for the deterministic regulation of helical and Dean vortices through geometric confinement.

Arterial spin labelling (ASL) is a non-invasive magnetic resonance imaging (MRI) method. ASL techniques can quantitatively measure cerebral perfusion by fitting a kinetic model to the difference between labelled images (tag images) and ones which are acquired without labelling (control images). ASL functional MRI (fMRI) provides quantitative perfusion maps by using arterial water as an endogenous tracer instead of depending on vascular blood oxygenation level.

Light treatment can effectively inhibit fresh-cut apple fruit browning, but the regulatory mechanism remains unknown. Here, we discovered that violet LED (Light-Emitting-Diode) light treatment significantly reduced fresh-cut apple fruit browning.

However, there are few reports on hyperbaric oxygen treatment for paroxysmal sympathetic hyperactivity at home and abroad, and the clinical experience is very limited. To understand the efficacy of hyperbaric oxygen treatment for paroxysmal sympathetic hyperactivity after brain injury, this retrospective study was conducted in the adult intensive care units of five medical centers in central China.

Objectives: The primary objective evaluated changes in clinically significant exacerbations (CSEs; defined as use of oral corticosteroids (OCS) or emergency department (ED) visits and/or hospitalizations) in the 12 months pre- and post-mepolizumab treatment. Secondary objectives assessed changes in the number of CSEs requiring ED visits/hospitalizations and daily maintenance OCS (mOCS) dosage 12 months pre- and post-mepolizumab treatment.
