TWDM-PON With Signal Remodulation and Rayleigh Noise Circumvention for NG-PON2

IEEE Photonics Journal, 2013
We propose and demonstrate a 40-Gb/s (4 × 10 Gb/s) downstream and 10-Gb/s (4 × 2.5 Gb/s) upstream time-wavelength-division-multiplexed passive optical network (TWDM-PON) using signal remodulation. Here, a downstream differential-phase-shift-

Semantic variant primary progressive aphasia with ANXA11 p.D40G

Alzheimer's &Dementia, Volume 21, Issue 3, March 2025.
Abstract INTRODUCTION Pathogenic variants of annexin A11 (ANXA11) have been identified in patients with amyotrophic lateral sclerosis (ALS) with or without frontotemporal dementia (FTD). We explored ANXA11 pathogenic variants in a Korean FTD cohort to investigate the prevalence and the role of ANXA11 variation in FTD.

Cardiovascular Insufficiency, Abdominal Sepsis, and Patients’ Age Are Associated with Decreased Paraoxonase‐1 (PON1) Activity in Critically Ill Patients with Multiple Organ Dysfunction Syndrome (MODS)

Disease Markers, Volume 2019, Issue 1, 2019., 2019
Oxidative stress and uncontrolled inflammation are hallmarks of sepsis, leading to organ failure and death. As demonstrated in animal studies, oxidative stress can be alleviated by antioxidant therapies. Paraoxonase‐1 (PON1) is a serum‐based antioxidant, anti‐inflammatory agent, detoxifier, and quorum‐sensing factor found to be a prognostic marker in ...

Paraoxonase‐2 agonist vutiglabridin promotes autophagy activation and mitochondrial function to alleviate non‐alcoholic steatohepatitis

British Journal of Pharmacology, Volume 181, Issue 19, Page 3717-3742, October 2024.
Abstract Background and Purpose Only limited therapeutic agents have been developed for non‐alcoholic steatohepatitis (NASH). Glabridin, a promising anti‐obesity candidate, has only limited druggability due to its low in vivo chemical stability and bioavailability.
