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.

PROGETTO E REALIZZAZIONE DI UN SISTEMA PER L'ADATTAMENTO AUTOMATICO DELL'IMPEDENZA D'INGRESSO DI UN'ANTENNA. [PDF]

, 2014
This document describes the design of an automatic matching network control system used to solve some impedance matching problems. All current matching networks are driven in half-automatic way, so they do not allow providing real-time matching between ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Paper-based methodology for investigation of triboelectric nanogenerators

Energy Reports, 2019
Triboelectric nanogenerators (TENGs) have been investigated as a promising methodology to harvest mechanical energy into electricity. The matching impedance and the transient property of TENGs are important for their practical application.

Electrolyte gate dependent high-frequency measurement of graphene field-effect transistor for sensing applications

, 2014
We performed radiofrequency (RF) reflectometry measurements at 2.4 GHz on electrolyte-gated graphene field-effect transistors (GFETs) utilizing a tunable stub-matching circuit for impedance matching.

Nicotinamide N‐methyltransferase promotes drug resistance in lung cancer, as revealed by nascent proteomic profiling

Molecular Oncology, EarlyView.
AZD9291 has shown promise in targeted cancer therapy but is limited by resistance. In this study, we employed metabolic labeling and LC–MS/MS to profile time‐resolved nascent protein perturbations, allowing dynamic tracking of drug‐responsive proteins. We demonstrated that increased NNMT expression is associated with drug resistance, highlighting NNMT ...

Development and Application of External Moving Type Calibration Device for Beam Detector Based on Quasi-impedance Matching Transmission

Yuanzineng kexue jishu, 2022
The beam calibration results are affected by the impedance of the calibration device. If impedance matching is not maintained, reflected signals would be generated, which would lead to the superposition of reflected signals and excitation signals ...

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

Theoretical research on the application of impedance calculation in the design of high-intensity low-frequency acoustic generator

Journal of Low Frequency Noise, Vibration and Active Control
The impedance matching is essential in producing high-intensity acoustic waves. This paper studies the impedance calculation methods of modulators and double-chamber Helmholtz resonators based on fluid mechanics, aeroacoustics, and electro-acoustic ...
