YouTube Videos on Botulinum Toxin A for Wrinkles: A Useful Resource for Patient Education.

Background: Patients interested in botulinum toxin type A (BTX-A) for wrinkles search for videos on YouTube, but little is known about the quality and reliability of the content.

Objective: The authors examined the quality, reliability, content, and target audience of YouTube videos on BTX for wrinkles.

Materials And Methods: In this cross-sectional study, the term "Botox" was searched on YouTube.

Phylogenetic characterization and promoter expression analysis of a novel hybrid protein disulfide isomerase/cargo receptor subfamily unique to plants and chromalveolates.

Protein disulfide isomerases (PDIs) play critical roles in protein folding by catalyzing the formation and rearrangement of disulfide bonds in nascent secretory proteins. There are six distinct PDI subfamilies in terrestrial plants. A unique feature of PDI-C subfamily members is their homology to the yeast retrograde (Golgi-to-endoplasmic reticulum) cargo receptor proteins, Erv41p and Erv46p.
