Real‐Time Observation of Soliton Buildup and Self‐Organization in a GHz Harmonic Mode Locked Fiber Laser

Laser &Photonics Reviews, EarlyView.
This image is an experimental recording of the buildup of harmonic mode‐locking in a fiber laser. The horizontal dimension corresponds to one cavity round trip, where the laser field intensity is displayed in a color scale. The vertical dimension is the evolution time in logarithmic scale, spanning from microseconds to seconds.

Prolonged Pulsed Radiofrequency Treatment in Resistant Trigeminal Neuralgia: A Case Report

Archives of Anesthesia and Critical Care
Trigeminal neuralgia (TN) is one of the most severe painful conditions known to man. Contradictory results regarding the effectiveness of pulsed radiofrequency (PRF) treatment of the trigeminal ganglion have been published in the literature. In the past

Efficacy and Safety of Small‐Spot 755 nm Picosecond Laser‐Induced Optical Breakdown for Novel Photomechanical Skin Ablation in Asian Patients

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Conventional ablative and photothermal lasers are commonly used to treat superficial pigmentary lesions but often induce thermal injury and post‐inflammatory hyperpigmentation (PIH), particularly in Asian skin. Picosecond 755‐nm alexandrite lasers with diffractive lens arrays (DLA) create laser‐induced optical breakdown (LIOB ...

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

A combination of low-temperature radiofrequency thermocoagulation and pulsed radiofrequency of the bilateral Gasserian ganglion for bilateral trigeminal neuralgia due to multiple sclerosis: a case report

JA Clinical Reports
Background Bilateral trigeminal neuralgia secondary to multiple sclerosis is an extremely rare condition. When Gasserian ganglion block is performed, it is necessary to achieve reliable long-term analgesic effects while avoiding treatment-related ...

Pulsed Radiofrequency Neuromodulation of Peripheral Nerve Injury [PDF]

, 2011
Pulsed-radiofrequency neuromodulation (PRF) is a pain management technique that involves placing a needle electrode near nerves and generating electrical current pulses in order to modulate the transduction of somatosensory information through those ...

Sagittal alignment to predict efficiency in pulsed radiofrequency for cervical facet joint pain

Scientific Reports
Neck pain due to cervical facet joint pain has a prevalence of 36–60% in chronic neck pain. Pulsed radiofrequency for such pain has been verified. After proper patient selection, pulsed radiofrequency of the cervical facet joints provide long-term pain ...
