Damage limitation: comparing the impact of polymers on bleached hair, when applied within or as post-bleach treatments [PDF]

, 2017
Hair bleaching causes undesirable chemical and structural changes to the cortex, the most prominent process being the oxidation of the disulphide bonds of the amino acid cystine and the creation of cysteic acid.

Gorab deficiency in skin dermis accelerates aging and is associated with dysregulation of RCHY1‐mediated P53 ubiquitination

Animal Models and Experimental Medicine, EarlyView.
Based on a dermis fibroblast Gorab knockout mouse model, this study revealed that Gorab deficiency promotes skin aging by influencing RCHY1, causing a decrease in P53 ubiquitination, damaging the activity of HDAC2, further resulting in the accumulation of aging‐related proteins (P53, P21, P16) and a reduction in extracellular matrix (ECM) components ...

Human hair keratin responds to oxidative stress via reactive sulfur and supersulfides

Advances in Redox Research
Keratin is a central component of human hair proteins, which explicitly possesses many cysteine residues (Cys-SH). For a long time, these Cys-SH residues were believed to contribute to human hair strength by forming intra- and inter-molecular disulfide ...

Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

The Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
