Sleeve bridging of the rhesus monkey ulnar nerve with muscular branches of the pronator teres: multiple amplification of axonal regeneration

open access: yesNeural Regeneration Research, 2015
Multiple-bud regeneration, i.e., multiple amplification, has been shown to exist in peripheral nerve regeneration. Multiple buds grow towards the distal nerve stump during proximal nerve fiber regeneration.

GeV detection of HESS J0632+057 [PDF]

open access: yes, 2017
HESS J0632+057 is the only gamma-ray binary that has been detected at TeV energies, but not at GeV energies yet. Based on nearly nine years of Fermi Large Area Telescope (LAT) Pass 8 data, we report here on a deep search for the gamma-ray emission from ...

Lactulose enhances neuroplasticity to improve cognitive function in early hepatic encephalopathy

open access: yesNeural Regeneration Research, 2015
Lactulose is known to improve cognitive function in patients with early hepatic encephalopathy; however, the underlying mechanism remains poorly understood.

Loss of microRNA-124 expression in neurons in the peri-lesion area in mice with spinal cord injury

open access: yesNeural Regeneration Research, 2015
MicroRNA-124 (miR-124) is abundantly expressed in neurons in the mammalian central nervous system, and plays critical roles in the regulation of gene expression during embryonic neurogenesis and postnatal neural differentiation.

Dorsal root ganglion neurons promote proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells

open access: yesNeural Regeneration Research, 2015
Preliminary animal experiments have confirmed that sensory nerve fibers promote osteoblast differentiation, but motor nerve fibers have no promotion effect.

A New Approach to Constrain Black Hole Spins in Active Galaxies Using Optical Reverberation Mapping [PDF]

open access: yes, 2014
A tight relation between the size of the broad-line region (BLR) and optical luminosity has been established in about 50 active galactic nuclei studied through reverberation mapping of the broad Hbeta emission line.

Large animal models of human cauda equina injury and repair: evaluation of a novel goat model

open access: yesNeural Regeneration Research, 2015
Previous animal studies of cauda equina injury have primarily used rat models, which display significant differences from humans. Furthermore, most studies have focused on electrophysiological examination.

The X-ray modulation of PSR J2032+4127/MT91 213 during the Periastron Passage in 2017 [PDF]

open access: yes, 2018
We present the Neil Gehrels Swift Observatory (Swift), Fermi Large Area Telescope (Fermi-LAT), and Karl G. Jansky Very Large Array (VLA) observations of the gamma-ray binary PSR J2032+4127/MT91 213, of which the periastron passage has just occurred in ...

Epistatic evidence for gender-dependant slow neurotransmission signalling in substance use disorders: PPP1R12B versus PPP1R1B

open access: yesEBioMedicine, 2020
Background: Slow neurotransmission including DARPP-32 signalling is implicated in substance use disorders (SUDs) by experimental systems but not yet in the human aetiology. PPP1R12B, encoding another protein in the DARPP-32 family, hasn't been studied in
