Manipulating the Assembly and Architecture of Fibrillar Silk

Advanced Materials, EarlyView.
In this study, advanced in situ AFM, PiFM, and Cryo‐EM are leveraged to realize in situ observations of nucleation, growth, and degradation of silk nanofibrils. A clear picture of the assembly and structural evolution of regenerated silk nanofibrils is defined and demonstrates a novel strategy for manipulating their structure and properties, which ...

Leveraging Multifaceted Polyphenol Interactions: An Approach for Hair Loss Mitigation

Advanced Materials Interfaces, EarlyView.
This study presents tannic acid as an effective alternative to traditional hair loss treatments. Acting as an adhesion mediator, tannic acid binds to keratin on the hair surface and sequesters SCANDAL—a blend of salicylic acid, niacinamide, and dexpanthenol—allowing gradual release to hair follicles.

Progress and Application of Multifunctional Hydrogel in Radioactive Skin Injury

Advanced Materials Interfaces, EarlyView.
This review examines healing challenges in radiation‐wound injuries, where ionizing radiation impairs immune and tissue repair processes. Hydrogels, with their biocompatibility, antimicrobial properties, and drug delivery capabilities, present a transformative solution. It compares hydrogel efficacy in radiation‐induced versus common wounds, highlights

Arginine Promoted Ovarian Development in Pacific White Shrimp Litopenaeus vannamei via the NO-sGC-cGMP and TORC1 Signaling Pathways

Animals
This study aimed to evaluate the effects of arginine (0.5%, 1%, 1.5%, 2%, and 2.5% arginine supplementation levels were selected) on the ovarian development of Pacific white shrimp (Litopenaeus vannamei).

The Biosynthetic Order of Amino Acid Addition to the Genetic Code [PDF]

arXiv, 2002
The previously formulated model for the evolution of the genetic code was shown to clarify why base triplets of some precursor amino acids differ by a single base from product amino acid codons, while others show less homology. First, the model indicated that the direction of code evolution changed on expansion from the N-fixers code (stage 2).
