Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Geometry of the Solutions of Localized Induction Equation in the Pseudo-Galilean Space

open access: yesAdvances in Mathematical Physics, 2015
We study the surfaces corresponding to solutions of the localized induction equation in the pseudo-Galilean space G31. We classify such surfaces with null curvature and characterize some special curves on these surfaces in G31.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

On special 𝑊-surfaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1955
A W-surface (2) is called special if fH5O at every umbilic. Apparently there are very few closed special W-surfaces.1 The following theorem is due to H. Hopf:2 The only closed special analytic W-surfaces of genus zero are spheres. It was P. Hartman and A. Wintner3 who succeeded in removing the analyticity assumption in Hopf's Theorem. Their theorem can

Editorial for the special section on implicit surfaces [PDF]

open access: yesThe Visual Computer, 2004
This special section is the first of two that will be devoted to a topic of growing importance, that is the field of implicit surfaces or implicit modelling as it is also known. The first of these papers, describes a fast adaptive algorithm for polygonizing an implicit surface.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Helix surfaces in the special linear group [PDF]

open access: yes, 2016
We characterize helix surfaces (constant angle surfaces) in the special linear group SL(2,R). In particular, we give an explicit local description of these surfaces by means of a suitable curve and a 1-parameter family of isometries of SL(2,R)

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Physiologically Significant Specializations of the Cell Surface [PDF]

open access: yesCirculation, 1962
This paper presents a brief review of the ultrastructure of some of the structural elaborations of the plasma membrane that may be regarded as adaptations for specific cell functions. Among the relatively stable specializations of the free surface, it considers the striated border of the intestinal mucosa, the brush border in the nephron, and ...
