A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

A Reduced Reference Image Quality Measure Using Bessel K Forms Model for Tetrolet Coefficients

, 2011
In this paper, we introduce a Reduced Reference Image Quality Assessment (RRIQA) measure based on the natural image statistic approach. A new adaptive transform called "Tetrolet" is applied to both reference and distorted images.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

CAMERA CONTROL ALGORITHM AND IMAGE QUALITY ASSESSMENT METHOD TO OBTAIN A QUALITY IMAGE

Сучасні інформаційні системи
Since small-sized objects are expressed in the image with very few pixels and are located at a fairly large distance from the camera, their recognition by computer vision-supported systems becomes difficult.

Face Image Quality Assessment

, 2021
Ytelsen på ansiktgjenkjenningssystmer er avhengig av kvaliteten på bildene for å kunne teste og trene disse systemene. For å automatisk vurdere kvaliteten på ansiktsbilder blir Face Image Quality Metrics (FIQMs) benyttet. Slike kvalitetsmetrikker gir objektive resultater som korresponderer med hvor synlig ansiktet i et bilde er.

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

Molecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.
