YIPFα1A expression is regulated by multilayered molecular mechanisms

FEBS Open Bio, EarlyView.
YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.

Circular Dichroism and Cross Polarization Conversion Using Chiral Metasurface

IEEE Open Journal of Antennas and Propagation
This paper presents a novel dual-mode chiral metasurface (CM) designed to achieve strong circular dichroism (CD) in both transmission and reflection mode within the Ku-band.

Design and Investigation of Differential-Fed Ultra-Wideband Patch Antenna with Polarization Diversity

International Journal of Antennas and Propagation, 2016
A novel single- or dual-polarized ultra-wideband (UWB) patch antenna fed by coupled feeding mechanism is proposed. The single-polarized antenna consists of a square ring patch and two Γ-shaped patches which are coupled to the radiating patch.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Design and simulation of a novel circularly polarized antenna with polarization reconfigurable characteristics

MATEC Web of Conferences, 2016
A novel circularly polarized antenna with polarization reconfigurable characteristics was designed using co-simulation of Ansoft HFSS and Designer software. It consists of a dual-polarized antenna and phase switching network which act as the feed network

On isometric full embeddings of symplectic dual polar spaces into Hermitian dual polar spaces

Linear Algebra and its Applications, 2009
Let \({\mathbb K}'\), \({\mathbb K}\) be (finite or infinite) fields such that \({\mathbb K}'\) is a quadratic Galois extension of \({\mathbb K}\) and let \(\theta\) denote the unique nontrivial element in \(\text{Gal}({\mathbb K}'/{\mathbb K})\). The dual polar space \(DW(2n-1,{\mathbb K})\), \(n\geq\,2\), has up to equivalence a unique isometric full

Valuations and hyperplanes of dual polar spaces

Journal of Combinatorial Theory, Series A, 2005
In einer früheren Arbeit haben die beiden Autoren auf die Bedeutung von so genannten Bewertungen bei der Klassifikation von near polygons hingewiesen. In der vorliegenden Arbeit werden solche Bewertungen bei dualen Polarräumen untersucht. \textit{P. J. Cameron} hat in [Geom.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.
