Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Clinical, organisational and policy factors influencing the implementation of nurse-led models of long-acting reversible contraception and medication abortion care in Australian general practice: A qualitative exploration

open access: yesSSM - Health Systems
Background: Access to sexual and reproductive healthcare in rural and regional areas is often limited, particularly for contraception and abortion care.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Sphère locale et espace public

open access: yesLien Social et Politiques, 1998
La complexité du système local en France se manifeste par la pluralité des acteurs institutionnels ou proches de leurs attentes, par la fragmentation des politiques et des territoires.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Slashdot and the public sphere

open access: yesFirst Monday, 2000
Jurgen Habermas's theory of the public sphere provides a model of idealised democratic debate. Three major features of this model can be identified - universal access, rational debate, and a disregard for rank. I analyse the model, and use it to examine Slashdot, a popular Web site, as an actualisation of public space.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Political communication in and about crises. Potentials of a fragmented field

open access: yesStudies in Communication Sciences, 2019
While there is growing interest in political crises in political communication research, crisis has not yet become a meaningful concept. Also, research tends to be reactive, which is suggested by an analysis of when and how the “crisis” label occurred in

Media, Religion, and the Public Sphere

open access: yesReligions, 2023
In the present study, I undertake to show that the public sphere can be constructed within the frames of a discourse loaded with religious symbols, either as part of religious institutions and manifestations, or, in a more interesting case, through the ...
