Anomalous diffusion induced by cristae geometry in the inner mitochondrial membrane

open access: yes, 2009
Diffusion of inner membrane proteins is a prerequisite for correct functionality of mitochondria. The complicated structure of tubular, vesicular or flat cristae and their small connections to the inner boundary membrane impose constraints on the ...

Decoupling Hybrid Metal Walls and Half-Wavelength Diagonal Open-Slots Based Four-Port Square Patch Antenna With High Port Isolation and Low Radiation Correlation for 2.4/5/6 GHz WiFi-6E 4 × 4 MIMO Access Points

open access: yesIEEE Access, 2022
Based on applying the hybrid metal walls and half-wavelength diagonal open-slots, a four-port square patch antenna (SPA) having high port isolation (>20 dB) and low radiation correlation (envelope correlation coefficients < 0.01) for 2.4/5 ...

Numb is not a critical regulator of Notch-mediated cell fate decisions in the developing chick inner ear.

open access: yes, 2015
The Notch signaling pathway controls differentiation of hair cells and supporting cells in the vertebrate inner ear. Here, we have investigated whether Numb, a known regulator of Notch activity in Drosophila, is involved in this process in the embryonic ...

WIKIBrainStem: An online atlas to manually segment the human brainstem at the mesoscopic scale from ultrahigh field MRI

open access: yesNeuroImage, 2021
The brainstem is one of the most densely packed areas of the central nervous system in terms of gray, but also white, matter structures and, therefore, is a highly functional hub.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Challenges and opportunities for implementation of substance misuse interventions in conflict-affected populations

open access: yesHarm Reduction Journal, 2018
Alcohol and other drug misuse are significant but neglected public health issues in conflict-affected populations. In this article, we review the literature on the challenges and strategies for implementing substance misuse treatment and prevention ...

Crystal structure of the ATPase domain of the human AAA+ protein paraplegin/SPG7. [PDF]

open access: yesPLoS ONE, 2009
Paraplegin is an m-AAA protease of the mitochondrial inner membrane that is linked to hereditary spastic paraplegias. The gene encodes an FtsH-homology protease domain in tandem with an AAA+ homology ATPase domain.

The inner structure of pyramid and capital structure: Evidence from China [PDF]

open access: yes, 2014
This paper examines the relationship between capital structure and the inner structure of pyramid in an emerging market economy country. The author uses firm-level panel data of Chinese listed companies to analyze the influence of the inner structure of ...

Computational Model of Outer Circle and Inner Ellipse Shield Tunnel Lining Structure

open access: yes, 2021
Subway tunnels are mostly located in strata with an uneven pressure. This uneven pressure is usually manifested by lateral pressure coefficients less than 1.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
