PT-symmetric phonon laser under gain saturation effect
(The Optical Society, 2020-07-20)As an analog of optical laser, phonon laser has potential applications in various areas. We study a type of phonon laser implemented by two coupled micro-cavities, one of which carries optical gain medium. The phonon laser ... -
Mechanical oscillations frozen on discrete levels by two optical driving fields
(American Physical Society, 2020-07-20)We report a synchronization phenomenon which is simulated with an optomechanical system driven by two equally strong fields with different frequencies. Once the frequencies of the driving fields are properly matched, the ... -
Semi-exact solutions of sextic potential plus a centrifugal term
(SPRINGER, 2020-11)We revisit the one-dimensional quantum system of a sextic potential added with a centrifugal term, V(x)=ax(-2)+bx(2)+cx(4)+dx(6), where the parameters a,b,c and d are arbitrary. We find that its solutions can be expressed ... -
Control of interference and diffraction of a three-level atom in a double-slit scheme with cavity fields
(American Physical Society, 2020-09-28)A double-cavity with a quantum mechanical and a classical field is placed immediately behind a double-slit in order to analyze the wave-particle duality. Both fields have common nodes and antinodes through which a three-level ... -
Ultra-high optical nonreciprocity with a coupled triple-resonator structure
(IOP Publishing Ltd., 2021)Optical transmission nonreciprocity as a widely investigated phenomenon is essential to various applications. Many sophisticated mechanisms have been proposed and tested for achieving the optical nonreciprocity on integrated ... -
Controlling parameters of the wave-particle duality of a two-level atom in a double-slit scheme with cavity field
(The Optical Society, 2021-01)A double-slit scheme placed immediately before a standing wave allows one to establish two possible paths for the passage of an atom. Each path matches with a node or antinode of the wave. The atom–field interaction is ... -
Mutual Information and Quantum Discord in Quantum State Discrimination with a Fixed Rate of Inconclusive Outcomes
(MDPI Multidisciplinary Digital Publishing Institute, 2021-01-6)We studied the mutual information and quantum discord that Alice and Bob share when Bob implements a discrimination with a fixed rate of inconclusive outcomes (FRIO) onto two pure non-orthogonal quantum states, generated ... -
Teased Fiber Preparation of Myelinated Nerve Fibers from Peripheral Nerves for Vital Dye Staining and Immunofluorescence Analysis
(Humana Press, 2018)Glial cells regulate a wide variety of neuronal functions during physiological and pathological conditions. Therefore, the study of glial cells and their association with axons is of paramount importance in order to ... -
Purification of Exosomes from Primary Schwann Cells, RNA Extraction, and Next-Generation Sequencing of Exosomal RNAs
(Humana Press, 2018)Exosomes are small (30-150 nm) vesicles of endosomal origin secreted by most cell types. Exosomes contain proteins, lipids, and RNA species including microRNA, mRNA, rRNA, and long noncoding RNAs. The mechanisms associated ... -
In Vitro Analysis of the Role of Schwann Cells on Axonal Degeneration and Regeneration Using Sensory Neurons from Dorsal Root Ganglia
(Humana Press, 2018)Sensory neurons from dorsal root ganglion efficiently regenerate after peripheral nerve injuries. These neurons are widely used as a model system to study degenerative mechanisms of the soma and axons, as well as regenerative ... -
A dual role for Integrin alpha 6 beta 4 in modulating hereditary neuropathy with liability to pressure palsies
(WILEY, 2018-05)Peripheral myelin protein 22 (PMP22) is a component of compact myelin in the peripheral nervous system. The amount of PMP22 in myelin is tightly regulated, and PMP22 over or under-expression cause Charcot-Marie-Tooth 1A ... -
Regulation of developing myelin sheath elongation by oligodendrocyte calcium transients in vivo
(NATURE PUBLISHING GROUP, 2018-01)How action potentials regulate myelination by oligodendrocytes is uncertain. We show that neuronal activity raises [Ca2+](i) in developing oligodendrocytes in vivo and that myelin sheath elongation is promoted by a high ... -
The Enigmatic Role of C9ORF72 in Autophagy
(FRONTIERS MEDIA SA, 2017-08-03)Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease characterized by the loss of motor neurons resulting in a progressive and irreversible muscular paralysis. Advances in large-scale genetics and ... -
Insulin-like growth factor 2 (IGF2) protects against Huntington's disease through the extracellular disposal of protein aggregates
(SPRINGER, 2020-11)Impaired neuronal proteostasis is a salient feature of many neurodegenerative diseases, highlighting alterations in the function of the endoplasmic reticulum (ER). We previously reported that targeting the transcription ... -
Correction: The necroptosis machinery mediates axonal degeneration in a model of Parkinson disease (vol 32, pg 274, 2019)
(Chile. Universidad Mayor, 2020-07)Correction to: Cell Death & Differentiation https://doi.org/10.1038/s41418-019-0408-4. Since online publication of this article, the authors noticed that reference details provided for references 65 and 66 were incorrect. ... -
The necroptosis machinery mediates axonal degeneration in a model of Parkinson disease
(NATURE PUBLISHING GROUP, 2020-04)Parkinson's disease (PD) is the second most common neurodegenerative condition, characterized by motor impairment due to the progressive degeneration of dopaminergic neurons in the substantia nigra and depletion of dopamine ... -
Axonal Degeneration Is Mediated by Necroptosis Activation
(SOC NEUROSCIENCE, 2019-05-15)Axonal degeneration, which contributes to functional impairment in several disorders of the nervous system, is an important target for neuroprotection. Several individual factors and subcellular events have been implicated ... -
