Since the conception of RNA nanotechnology (Cell, 94:147, 1998), there has been tremendous interest in its application for the functional delivery of RNA into cells. Splice-switching oligonucleotides (SSOs) are an emerging antisense drug class with the ability to therapeutically modify gene expression. A wide variety of chemical modifications have been devised to try to increase the activity and stability of SSOs. Also, as with most nucleic acid therapeutics, delivery into the cell is the major hurdle for in vivo and clinical applications. As a result, various RNA nanoparticles are being constructed for targeted delivery of therapeutics. However, it is difficult to find a practical assay to measure splice-switching activity. Here, we describe a model delivery system that can be used as a convenient, high-throughput assay to quantitatively measure the functional delivery and splicing redirection in a live human melanoma cell line.

Extracellular vesicles (EVs), defined as membrane-bound vesicles released from all cells, are being explored for their diagnostic and therapeutic role in dry eye disease (DED). We systematically shortlisted 32 articles on the role of EVs in diagnosing and treating DED. The systematic review covers the progress in the last 2 decades about the classification and isolation of EVs and their role in DED.

Purpose: Recovery rate of rod photoreceptor sensitivity (S2 gradient) following a bleach is reduced in age-related macular degeneration (AMD) due to diminished delivery of retinol across a grossly altered Bruch's membrane. Since triterpenoid saponins are known to improve transport across Bruch's, we have assessed their possible use for reversing the visual deficits in AMD.

Background: Data on the effect of mineralocorticoid receptor antagonist therapy on HbA levels and new-onset diabetes are conflicting. We aimed to examine the effect of oral finerenone, compared with placebo, on incident diabetes in the Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients with Heart Failure (FINEARTS-HF) trial.
Methods: In this randomised, double-blind, placebo-controlled trial, 6001 participants with heart failure with New York Heart Association functional class II-IV, left ventricular ejection fraction 40% or higher, evidence of structural heart disease, and elevated N-terminal pro-B-type natriuretic peptide levels were randomly assigned to finerenone or placebo, administered orally.

Diabetes is becoming more common worldwide, and people with diabetes are twice as likely to experience heart problems compared to those without diabetes. These cardiovascular complications are the foremost cause of mortality among people with diabetes. A specific form of heart failure known as "diabetic cardiomyopathy" can develop in individuals with diabetes.

Unlabelled: a natural inhabitant of the human body, is a promising candidate vehicle for vaccine delivery. An obstacle in developing bacterial delivery vehicles is generating a production strain that lacks antibiotic resistance genes and contains minimal foreign DNA. To deal with this obstacle, we have constructed a finetuned, inducible two-plasmid CRISPR/Cas9-system for chromosomal gene insertion in .
