Growth in a Turing Model of Cortical Folding

open access: yesBiomath, 2012
The brain's cerebral cortex is folded into many gyri (hills) and sulci (valleys). Little is known about how the cortex folds or why the folds are located where they are.

Skin Barrier Formation: The Membrane Folding Model [PDF]

open access: yesJournal of Investigative Dermatology, 2001
We propose that skin barrier morphogenesis may take place via a continuous and highly dynamic process of intersection-free membrane unfolding with a concomitant crystallization of the emerging multilamellar lipid structure representing the developing skin barrier.

Folding model analysis of alpha radioactivity [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2003
Radioactive decay of nuclei via emission of $α$ particles has been studied theoretically in the framework of a superasymmetric fission model using the double folding (DF) procedure for obtaining the $α$-nucleus interaction potential. The DF nuclear potential has been obtained by folding in the density distribution functions of the $α$ nucleus and the ...

Ring-like N-fold Models of Aβ42 fibrils [PDF]

open access: yesScientific Reports, 2017
AbstractWhen assembling as fibrils Aβ40 peptides can only assume U-shaped conformations while Aβ42 can also arrange as S-shaped three-stranded chains. We show that this allows Aβ42 peptides to assemble pore-like structures that may explain their higher toxicity.

Protein GB1 folding and assembly from structural elements. [PDF]

open access: yes, 2009
Folding of the Protein G B1 domain (PGB1) shifts with increasing salt concentration from a cooperative assembly of inherently unstructured subdomains to an assembly of partly pre-folded structures.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Influence of ground-state structure and Mg2+ binding on folding kinetics of the guanine-sensing riboswitch aptamer domain [PDF]

open access: yes, 2011
Riboswitch RNAs fold into complex tertiary structures upon binding to their cognate ligand. Ligand recognition is accomplished by key residues in the binding pocket.

Application of an interpretable classification model on Early Folding Residues during protein folding

open access: yesBioData Mining, 2019
Background Machine learning strategies are prominent tools for data analysis. Especially in life sciences, they have become increasingly important to handle the growing datasets collected by the scientific community.

Nasolabial folds modeling — literature review

open access: yesJournal of Face Aesthetics, 2019
Introduction. Nasolabial folds are skin folds that run from both sides of the nose to the corners of the mouth. They are caused by the loss of fat in the dermis, followed by the loss of muscles in the middle part of the face.Aim. The aim of the work is to present contemporary knowledge of materials used for modeling nasolabial folds.Material and ...
