Dry/Wet Cycling and the Thermodynamics and Kinetics of Prebiotic Polymer Synthesis

open access: yesLife, 2016
The endoergic nature of protein and nucleic acid assembly in aqueous media presents two questions that are fundamental to the understanding of life’s origins: (i) how did the polymers arise in an aqueous prebiotic world; and (ii) once formed in some ...

Non-enzymatic oligonucleotide ligation in coacervate protocells sustains compartment-content coupling

open access: yesNature Communications, 2023
Modern cells are complex chemical compartments tightly regulated by an underlying DNA-encoded program. Achieving a form of coupling between molecular content, chemical reactions, and chassis in synthetic compartments represents a key step to the assembly

How to Treat Skin Quality: A Consensus-Based Treatment Algorithm and Expert Guidance. [PDF]

open access: yesJ Cosmet Dermatol
ABSTRACT Introduction Skin quality can be described using four emergent perceptual categories (EPCs): skin tone evenness, skin surface evenness, skin firmness, and skin glow. While the publication in which the EPCs were originally described by Goldie et al.

Prebiotic selection for motifs in a model of template-free elongation of polymers within compartments. [PDF]

open access: yesPLoS ONE, 2017
The transition from prelife where self-replication does not occur, to life which exhibits self-replication and evolution, has been a subject of interest for many decades. Membranes, forming compartments, seem to be a critical component of this transition

Ablation of keratan sulfate accelerates early phase pathogenesis of ALS. [PDF]

open access: yesPLoS ONE, 2013
Biopolymers consist of three major classes, i.e., polynucleotides (DNA, RNA), polypeptides (proteins) and polysaccharides (sugar chains). It is widely accepted that polynucleotides and polypeptides play fundamental roles in the pathogenesis of ...
