The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Paradox of the Moving Boundary: Legal Heredity of River Accretion and Avulsion

Water Alternatives, 2011
International boundaries – the divisions between state jurisdictions – are characterised in law by their inherent rigidity. Yet recent research has revealed that well over one-third of the total length of international boundaries follow rivers or streams

Broad iron line as a relativistic reflection from warm corona in AGNs

Astronomy & Astrophysics
Context. We present that the broad feature usually observed in X-ray spectra at around 6.4 keV can be explained by ray-traced emission from the two-slab system containing a dissipative, warm corona on the top of an accretion disk in an active galactic ...

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Chemical evolution and kilonova implications of post-merger accretion disk winds

Astronomy & Astrophysics
Context. Several gamma-ray bursts (GRBs) have recently been associated with kilonova emission. We study the mechanisms that account for this effect by means of the radioactive decay of elements synthesized in accretion disk winds. Aims.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

A TESS view of post-eruption variability in novae V1405 Cas, V1716 Sco, and V1674 Her

Astronomy & Astrophysics
We analyzed TESS archival data of three novae after recent outbursts, searching for the orbital and white dwarf (WD) rotation period and possible variations in these periods.

Segmentation and cycles of crustal accretion at mid-ocean ridges: a study of the Reykjanes Ridge [PDF]

, 2003
Early studies of mid-ocean ridges suggest a fundamental difference between crustal accretionary processes at slow- and fast-spreading ridges. Accretion, and the supply of melt to the crust itself, is thought to be highly episodic at slow-spreading ridges

Neutralization of the PTX3/CD44 axis suppresses TGF‐β1 signaling in kidney fibrosis

FEBS Letters, EarlyView.
This study investigates how the PTX3/CD44 axis promotes kidney fibrosis by activating TGF‐β1 signaling. We demonstrate that the neutralizing antibody WHC‐001 effectively inhibits this pathway, suppressing myofibroblast activation and partial epithelial–mesenchymal transition (EMT).

Impact of magnetic field gradients on the development of the magneto-rotational instability

Astronomy & Astrophysics
Context. The magneto-rotational instability (MRI) plays a crucial role in accretion disk modelling, driving magnetohydrodynamic turbulence and facilitating enhanced angular momentum transport.
