Decreased Serum 5‐HT: Clinical Correlates and Regulatory Role in NMJ of MG

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although 5‐Hydroxytryptamine (5‐HT) indirectly stimulates muscle contraction and participates in regulating Acetylcholine receptor (AChR) cluster homeostasis in cellular, animal, and clinical studies, evidence regarding its potential to modulate muscle contraction in myasthenia gravis (MG) remains limited.

Peta-bit-per-second optical communications system using a standard cladding diameter 15-mode fiber

Nature Communications, 2021
Data rates in optical fiber networks have increased exponentially over the past decades and core-networks are expected to operate in the peta-bit-per-second regime by 2030.

Optical fiber metamagnetics

Optics Express, 2011
To date, magnetic and negative-index metamaterials at optical frequencies were realized on bulk substrates in the form of thin films with thicknesses on the order of, or less than, optical wavelengths. In this work, we design and experimentally demonstrate, for the first time, fiber-coupled magnetic metamaterials integrated on the transverse cross ...

Nationwide Survey of Atopic Myelitis and Plexin D1‐Immunoglobulin G‐Related Pain

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To elucidate the features of plexin D1‐immunoglobulin (Ig)G‐associated neuropathic pain and its relationship to atopic myelitis (AM) in a nationwide Japanese survey. Methods A preliminary survey questionnaire was sent to 1574 selected departments (neurology and pediatrics/pediatric neurology) to explore the numbers of AM and plexin ...

Distributed Optical Fiber Sensors Based on Optical Frequency Domain Reflectometry: A review

Italian National Conference on Sensors, 2018
Distributed optical fiber sensors (DOFS) offer unprecedented features, the most unique one of which is the ability of monitoring variations of the physical and chemical parameters with spatial continuity along the fiber.

Impact and Compensation of Electrical-to-Optical Frequency Response on Carrierless Phase Retrieval Receivers

IEEE Photonics Journal
On carrierless phase retrieval (PR) receivers based on direct detection, bandwidth limitation of electrical-to-optical (E/O) conversion at the transmitter side (Tx) distorts the modulated optical signal.

All-fiber optical nonreciprocity based on parity-time-symmetric Fabry-Perot resonators

Communications Physics, 2022
Optical nonreciprocity is of fundamental importance for signal processing in modern optical communication systems but is still facing issues on either high energy consumption, complicated design or on-chip integration.

Lessons Learned: Quality Analysis of Optical Coherence Tomography in Neuromyelitis Optica

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Optical coherence tomography (OCT)‐derived retina measurements are markers for neuroaxonal visual pathway status. High‐quality OCT scans are essential for reliable measurements, but their acquisition is particularly challenging in eyes with severe visual impairment, as often observed in neuromyelitis optica spectrum disorders ...

Depth-resolved fiber photometry with a single tapered optical fiber implant

Nature Methods, 2019
Fiber photometry is increasingly utilized to monitor fluorescent sensors of neural activity in the brain. However, most implementations are based on flat-cleaved optical fibers that can only interface with shallow tissue volumes adjacent to the fiber. We
