Chloroplast alchemy: rewriting the chloroplast genome with high precision.

In the past decade, precise genome editing has transitioned from theory to practical application. Yet, plastid genomes have largely remained impervious to these advances. A recent breakthrough by Mok et al.

Towards sustainable spirulina farming: Enhancing productivity and biosafety with a salinity-biostimulants strategy.

Arthrospira platensis (spirulina) is pivotal to the global microalgae industry, valued for its nutritional and bioactive properties. However, its sustainable production is challenged by freshwater scarcity and biological contaminants. This study introduces a salinity-biostimulants strategy to adapt a freshwater spirulina strain, CBD05, to near-seawater salinity (3 %).

Does injection of botulinum toxin to salivary glands require ultrasound guidance?

Introduction: Injection of botulinum toxin into salivary glands is a well-established treatment for sialorrhea in children, but the absolute need for radiological guidance has not been tested.

Methods: Single-centre study in which clinicians of varying seniority attempted blind injection of salivary glands, after which their position within or outside the gland was confirmed by ultrasound guidance before the injection is administered.

Results: 117 patients underwent botulinum toxin of salivary glands between November 2008 and August 2023, with 459 glands injected in total.

Investigating the effectiveness of commercially available mouthwash on SARS-CoV-2 in vivo using viable virus titre as the primary outcome. A randomised controlled trial.

This multi-arm, parallel group, single-blinded randomised controlled trial aimed to assess three commercially available mouthwashes effectiveness against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This manuscript has been written in accordance with the CONSORT statement. Eligible participants were SARS-CoV-2 positive with a positive test in the last 72 h.

Combining Enhanced Resolving Power with Duty Cycle Improvements on a Multi-Reflecting Time-of-Flight Mass Spectrometer.

The combination of enhanced resolving power and improved duty cycle on a multireflecting time-of-flight mass spectrometer is described. Resolving power increases are achieved by extending the effective ion path length from 47 m to greater than 200 m. Path length increases are achieved through containment of ions within the analyzer for up to = 5 passes using a pulsed deflection electrode.
