Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Negation as Infinite Affirmation

Diakrisis, 2019
The purpose of this paper is to identify the meaning of negation in Dionysius the Areopagite’s apophatism: how and towards which reality does it orient contemplation and what does it actually say about God who reveals Himself?

Sterile neutrinos in ${\Lambda }_b^0\to ({\Lambda }_c^{+},p^{+}){\ell }_1^{-}{\ell }_2^{-}{\ell }_3^{+}\nu$ decays

Physical Review, 2022
We study lepton number violating and lepton number conserving semileptonic decays of heavy baryons Λb0 to three charged leptons and a neutrino. The decays occur through two intermediate quasidegenerate GeV-scale sterile neutrinos of either Majorana or Dirac type that can be on-shell.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

FEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Decay $B_c^{+}\to D_{\left(s\right)}^{(*)+}{\ell }^{+}{\ell }^{-}$ within covariant confined quark model

Physical Review
We study the rare semileptonic decays of Bc mesons within the effective field theoretical framework of covariant confined quark model. The transition form factors corresponding to Bc+→D(*)+ and Bc+→Ds(*)+ are computed in the entire q2 range. Using form factors, we compute the branching fractions and compare them with the available theoretical results ...

${\overline{D}}_s^{(*)}{D}^{(*)}$ molecular state with $J^P=1^{+}$

Physical Review, 2021
In this paper, we construct D¯s(*)D(*)-molecule-type interpolating currents J(±)μ(x) with JP=1+, calculate the corresponding mass and magnetic moment using the QCD sum rule method and its extension in the weak electromagnetic field, and study the processes of Z(±)cs to ηcK*, J/ψK, D¯Ds*, and D¯*Ds via three-point sum rules. The numerical values are mZ(±
