Unconventional abdominal uses of FIESTA (CISS) sequence

open access: yesIndian Journal of Radiology and Imaging, 2013
The ability to provide cross-sectional imaging, combined with a lack of ionizing radiation has made magnetic resonance imaging (MRI) of abdomen popular. We report four interesting cases: Midgut malrotation with volvulus, sigmoid volvulus, biliary rupture

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.

Steady-state and tracking analysis of the SSLMS algorithm

open access: yes, 2018
This paper presents expressions for the steady-state mean-square error (MSE), the optimum stepsize, and the corresponding minimum value of the tracking MSE of the sign-sign least mean square (SSLMS) algorithm for the case of real-valued data.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

A Steady State ANN Model for the Operational Characteristics of a Variable Speed (VS) Direct Expansion (DX) Air Conditioning (A/C) System

open access: yesZhileng xuebao, 2017
In this study, an ANN model for an experimental VS DX A/C system was developed to predict its outputs with an assumption that the indoor air states will not influence the relative value of system outputs. Steady state experiments under a fixed indoor air

The modulation of steady-state responses by transcranial alternating current stimulation: a scoping review

open access: yesFrontiers in Systems Neuroscience
Transcranial alternating current stimulation (tACS) is a non-invasive technique that modulates brain oscillatory activity in a frequency-specific manner, offering potential for improving sensory and cognitive functions.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Steady State Tokamak Sustained by Bootstrap Current Without Seed Current

open access: yes, 1992
Steady state tokamak solution is studied by taking into account the current diffusivity. The seed current for generating the Bootstrap current is supplied through the radial diffusion of the Bootstrap current.
