Expanding the binding specificity for RNA recognition by a PUF domain

Nature Communications, 2021
The PUF RNAbinding domain has an eight-repeat structure with the ability to bind an eight-base RNA sequence. Here the authors generate a comprehensive library of variants of a PUF domain to find an RNA binding code and design PUF domains that recognize ...

Early‐Onset Gastric Cancer as a High‐Risk Disease Entity in the United States: Clinicopathologic Features, Regional Variation, and Outcomes

Cancer Medicine, Volume 15, Issue 8, August 2026.
ABSTRACT Introduction Early‐onset gastric cancer (EOGC), defined as diagnosis before age 45, represents a distinct and increasingly recognized subset of gastric cancer. Emerging evidence suggests that clinical behavior, treatment patterns, and outcomes differ from average‐onset disease, yet these differences remain incompletely characterized.

Synthesis of Polyols for Expanded Rigid Polyurethanes by Microwave Liquefaction of Kraft Lignin With Bio‐Based Solvents

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
This study produced bio‐based polyols from lignin using microwave liquefaction with bio‐derived solvents. The process was optimized by adjusting solvent composition and catalyst type to obtain high yields and a suitable hydroxyl number. Foams made from lignin‐based polyols showed comparable properties to commercial products.
