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 ...

PHYSICAL PROPERTIES OF SPECKLES [PDF]

open access: yes, 1978
Speckles are no longer regarded merely as a noise element, but as a carrier of information to be used in different applications. This offers a powerful and simple tool for studying surface roughness, for measuring displacement and strain, and for deformation and vibration analysis.

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 ...

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

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

Antioxidant Potential and Phenolic Compounds of Some Widely Consumed Turkish White Bean (Phaseolus vulgaris L.) Varieties

open access: yesPolish Journal of Food and Nutrition Sciences, 2016
The antioxidant potential and phenolic compounds content were investigated in ten white bean varieties widely consumed in Turkey. Total phenolic contents of seeds varied between 0.33 and 0.63 mg GAE/g.

Fuzzy modelling of prescribed burning effects on soil physical properties

open access: yes, 2009
This paper presents the preliminary work of an approach where Fuzzy Boolean Nets (FBN) are being used to extract qualitative knowledge regarding the effect of prescribed fire burning on soil chemical physical properties.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

High-Temperature Oxidation Behavior of AlxCoCr0.5NiPt0.1 (x = 0.5, 1.0) Multi-Principal Element Alloys at 1100 °C

open access: yesMetals
The microstructure, phase composition, and high-temperature oxidation behavior of Al0.5CoCr0.5NiPt0.1 and AlCoCr0.5NiPt0.1 multi-principal element alloys (MPEAs) at 1100 °C in air were investigated.

Magnetoelectronic properties of graphene dressed by a high-frequency field

open access: yes, 2016
Solving the Schrödinger problem for electrons in graphene subjected to both a stationary magnetic field and a strong high-frequency electromagnetic wave (dressing field), we found that the dressing field drastically changes the structure of Landau levels
