A Robust Reference Optical Spectrum Based in-Band OSNR Monitoring Method Suitable for Flexible Optical Networks

open access: yesIEEE Photonics Journal, 2020
The in-band OSNR monitoring methods based on the noise-free reference optical spectrum (ROS) have attracted much attention in the field of optical performance monitoring because they are cost-effective and insensitive to chromatic dispersion and ...

High LRIG1 expression predicts lymph node metastasis in patients with uterine cervical cancer

open access: yesFEBS Open Bio, EarlyView.
Lymph node status is crucial in determining treatment for women with early‐stage cervical cancer. We demonstrate that high LRIG1 protein expression in primary tumors can predict lymph node metastases. Our findings support further investigation of LRIG1 as a biomarker to improve staging accuracy and guide treatment decisions in cervical cancer patients.

Performance monitoring of long chains of optical amplifiers

open access: yesElectronics Letters, 1993
The monitoring and fault location of long chains of optical amplifiers such as will be deployed in undersea cable systems is an important design consideration. The Letter describes two methods which have been proposed and one which has been evaluated on our test bed simulator of 3100 km with OAs spaced at 45 km and operating at 5 Gbit/s.

Microbial profile of the appendix niche in acute appendicitis: a novel sampling approach

open access: yesFEBS Open Bio, EarlyView.
This study utilized a novel sampling method, ERAT (i.e. endoscopic retrograde appendicitis treatment)‐guided lumen aspiration, to obtain samples from the appendix, and shotgun metagenomic sequencing was performed for in situ characterization of the appendix microbiome in patients with acute appendicitis.

Structural and functional characterization of chitinase from carnivorous plant Drosera adelae

open access: yesFEBS Open Bio, EarlyView.
A class I chitinase from the carnivorous plant Drosera adelae was expressed and purified using a yeast system, revealing high enzymatic activity. Structural analyses of the catalytic and chitin‐binding domains identified key tyrosine residues involved in substrate binding, offering insights into the enzyme's adaptation for insect digestion.

Structural and functional analysis of Bacillus sarcosine oxidase and its activity toward cyclic imino acids

open access: yesFEBS Open Bio, EarlyView.
Sarcosine oxidase from Bacillus sp. (SoxB) recognizes l‐proline (l‐Pro), d‐proline (d‐Pro), and l‐thioproline (l‐Tpr) as minor substrates. In this study, we measured their absorption spectra, determined the crystal structures of their enzyme complexes, and performed site‐directed mutagenesis of key residues.

Multimodal Autonomic Biomarkers Predict Phenoconversion in Pure Autonomic Failure

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Pure autonomic failure (PAF) presents with autonomic failure without other neurological features. A third develop central neurological features, fulfilling criteria for multiple system atrophy (MSA) and Lewy body diseases (LBD), including Parkinson's disease and Dementia with Lewy bodies.
