Clues to tRNA Evolution from the Distribution of Class II tRNAs and Serine Codons in the Genetic Code

open access: yesLife, 2016
We have previously proposed that tRNAGly was the first tRNA and glycine was the first amino acid incorporated into the genetic code. The next two amino acids incorporated would have been the other two small hydrophilic amino acids serine and aspartic ...

A Colorimetric Procedure for the Determination of Aspartic Acid.

open access: yesExperimental Biology and Medicine, 1950
SummaryA procedure is described for the determination of aspartic acid in quantities of 0.5 mg or above in the sample. The amino acid is converted to fumaric acid and this is measured colorimetrically.

Hydrogel‐Based Smart Materials for Wound Healing and Sensing

open access: yesAggregate, EarlyView.
The graphical abstract illustrates the role of hydrogel‐based flexible materials in advancing biomedical applications, including wound healing, point‐of‐care diagnostics, smart patches, and wearable devices. Hydrogels are particularly promising in modern wound care due to their high‐water content, flexibility, and biocompatibility.

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota

open access: yesAngewandte Chemie, EarlyView.
Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...

A General Strategy to Fine‐Tune Group 14 Rhodamines for Ultrahigh Signal‐to‐Noise Ratio Labeling In Vivo by Nano‐Aggregation

open access: yesAggregate, EarlyView.
Group 14 rhodamines are one of the most widely explored fluorogenic probes with high signal‐to‐noise ratio (SNR). We have boosted the SNR of group 14 rhodamines by nano‐aggregation via a novel strategy by manipulating their dynamic physical and chemical states for the first time. The ultrahigh SNR fluorescence imaging offers a fundamental understanding

Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Linkages in thermal copolymers of lysine [PDF]

open access: yes
The thermal copolymerization of lysine with other alpha-amino acids was studied. The identity of the second amino acid influences various properties of the polymer obtained, including the proportion of alpha and epsilon linkages of lysine.
