The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

The importance of additional illumination in the cultivation of grafted cucumber seedlings and potato seedlings from botanical seeds

Овощи России
Relevance. Plants use light not only as an energy source for photosynthesis, but also as an important regulator of their growth and development. The characteristics of light, such as intensity, spectral composition, duration of illumination, as well as ...

Bandgap dependence of current crowding effect in 3–5 μm InAsSb/InAs planar light emitting devices [PDF]

, 2008
Electroluminescence power profiles and 2D micropatterns have been obtained from InAsSb/InAs planar LEDs tuned at several wavelengths within the 3–5 μm band. Light confined to a small region around the top opaque contact was observed (cw mode, I > 10 mA,

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Avalanche LEDs Based on Nanostructured Silicon for Microwave Frequency Range

Доклады Белорусского государственного университета информатики и радиоэлектроники
Development of an efficient light signal source is a basic necessity for the development of silicon photonics. Avalanche silicon light emitting diodes (LEDs) can serve as such a source. The article discusses avalanche LEDs based on nanostructured silicon.

Impact of light quality on the physiological characteristics of Capsicum chinense seeds

Advances in Horticultural Science, 2019
The objective of this work was to evaluate the physiological quality of Capsicum chinense seeds submitted to different light spectral qualities. It was used a completely randomized design, in a 4x5 factorial scheme, with four pepper cultivars [BRS moema ...
