Design of a Triple-band Microstrip Bandpass Filter with Wide Harmonic Suppression Based on Stepped-impedance Resonators

RMUTL Engineering Journal, 2023
This paper presents a triple-band microstrip bandpass filter with a broad harmonic suppression based on stepped-impedance resonators. This stepped-impedance resonator structure reduces the microstrip open-loop halfwave length resonator filter's circuit ...

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

A Novel Triple-Conductor Dual-Mode Resonator Based Dual-Band Filter [PDF]

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
As a simulation-based exploratory study, a novel and improved dual-mode resonator is proposed in this paper. By exploiting two asynchronous resonance modes that can be generated within the proposed resonator, such architectures can be utilized to ...

Compact Monolithic 3D-Printed Wideband Filters Using Pole-Generating Resonant Irises

IEEE Journal of Microwaves, 2023
The design concept of a pole-generating resonant iris is demonstrated in rectangular waveguide filters in this paper. Different from conventional reactive iris, the resonant iris can generate an extra transmission pole without increasing the number of ...

Reprogramming tumor cells with LCOR mRNA nanotherapy to enhance immunotherapy

Molecular Oncology, EarlyView.
LCOR (Ligand‐dependent corepressor) mRNA encapsulated in polymeric nanoparticles restores LCOR activity in tumor cells, constraining aggressive tumor cell states and increasing tumor immunogenicity. This reprogramming makes tumor cells more vulnerable to T‐cell attack and enhances their response to immune‐checkpoint immunotherapy.

Miniaturized full‐metal bandpass filter and multiplexer using circular spiral resonator

IET Microwaves, Antennas & Propagation, 2021
This article proposes a new class of miniaturized full‐metal bandpass filters (BPFs) and multiplexers using circular spiral resonators (CSRs). The proposed metal CSR is supported on the metal cavity's wall, which serves as a short‐end resonator. This CSR

Design of Compact Quasi-Elliptic Bandpass Filters Based on Coaxial Inset Resonators

IEEE Access, 2023
This article reports a novel inset resonator configuration for coaxial filter applications with quasi-elliptic responses. The design and analysis of the inset resonator are discussed in detail and accurately modeled as a capacitively-loaded stepped ...

An outer membrane vesicle‐associated two‐track model for enterotoxigenic Bacteroides fragilis oncogenesis

Molecular Oncology, EarlyView.
Enterotoxigenic Bacteroides fragilis is a gut bacterium linked to bowel cancer. We propose that its toxin acts along two routes: at the cell surface, cutting the adhesion protein E‐cadherin and triggering inflammation; and inside the cell, delivered by bacterial vesicles, switching on NOD1 and cancer stem cell programs.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Additively Manufactured and Monolithically-Integrated Triple-Mode Post-Loaded Cavity-Resonator-Based Bandpass Filters

IEEE Journal of Microwaves, 2023
This manuscript reports on a new class of triple-mode post-loaded cavity-resonator based bandpass filters (BPFs) alongside their design methodology and a monolithic integration scheme using stereolithography apparatus (SLA) 3D printing.
