pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

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 ...

Decompositions of modules into projective modules and CS-modules [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2000
Let M be a right R-module. It is shown that M is a locally Noetherian module if every finitely generated module in σ[M] is a direct sum of a projective module and a CS-module. Moreover, if every module in σ[M] is a direct sum of a projective module and a CS-module, then every module in σ[M] is a direct sum of modules which are either indecomposable ...

MASH structures for bandpass sigma-delta modulators

open access: yes, 1995
The paper presents simulation results from investigating the behaviour of multistage (MASH) oversampled bandpass sigma-delta (Σ-Δ) modulators for use in analogue to digital converters for high frequency narrowband applications such as the signals out of ...

Continuous time delta sigma modulators with reduced clock jitter sensitivity [PDF]

open access: yes, 2006
In this paper, a technique and method is presented to suppress the effect of clock-jitter in continuous-time delta-sigma modulators with switched-current (current-steering) digital to analogue converters.

Neuroprotective Effects of σ2R/TMEM97 Receptor Modulators in Neuronal Model of Huntington\u27s Disease

open access: yes, 2022
Huntington\u27s disease (HD) is a genetic neurodegenerative disease caused by an expanded CAG repeat in the human Huntingtin gene (HTT) that yields an expanded polyglutamine (polyQ) repeat in exon-1 of the human mutant huntingtin (mHTT) protein.

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Stability predictions for higher-order band-pass sigma-delta modulators for dual sinusoidal inputs

open access: yes, 2010
The stability boundaries of higher-order Band-Pass (BP) Σ-Δ modulators for dual sinusoidal inputs based on a combination of the Describing Function (DF) method and the quasi-linear modeling of the quantizer are determined in this paper.
