Temperature‐Modulated Threshold Response in a Volatile Memristor: Toward a Biomimetic Polymodal Nociceptive System

Advanced Functional Materials, EarlyView.
This study demonstrates an artificial polymodal nociceptor whose firing threshold is actively modulated by temperature. A volatile TiN/TiOx/ZnO/TiOx/ITO memristor shows interfacial ion–driven resistive switching and membrane‐potential‐like dynamics, enabling temperature‐dependent nociceptive behavior.

Direct lateral interbody fusion with indirect decompression of the spinal roots in patients with degenerative lumbar spinal stenosis

Гений oртопедии
Introduction Degenerative spine conditions involve the gradual loss of normal structure of the spine among the population and remain a common form of work-limiting health condition in 80 % of the population.

Sudden paraparesis due to spinal cord ischemia with initial contrast enhancement of the cauda equina and time-delayed owl-eyes sign on follow-up MR imaging: a case report

Neurological Research and Practice, 2021
We report on a case of a 52-year-old male with sudden paraparesis. The initial MRI showed contrast enhancement of the conus medullaris and the complete cauda equina.

SENSORY REGRESSION TIME FROM SUBARACHNOID BLOCK WITH HYPERBARIC 0.75% BUPIVACAINE IN THE OBESE PATIENT [PDF]

, 1989
The purpose of this study was to determine if obese patients have a different sensory regression time from subarachnoid block than non-obese patients using hyperbaric 0.75% bupivacaine. A quasi-experimental design was used. Twenty patients were separated

Intradural Communication of L3 and L4 Ventral Nerve Rootlets of Spinal Nerves

Siriraj Medical Journal, 2004
Normally, the nerve roots within the dural sec never communicate with one another. Even the fusion of the ventral and dorsal nerve roots to form the spinal nerve occurs outside the dural sac.

Bioactive Conductive Ti3C2Tx‐Ce Hydrogel Facilitates Spinal Cord Injury Repair Through ROS Scavenging and Mitochondrial Regulation

Advanced Functional Materials, EarlyView.
Bioactive conductive Ti3C2Tx‐Ce hydrogels with with scavenging ROS and alleviating neuronal mitochondrial dysfunction are exploited for SCI treatment. This functionality is attributed to interfacial activation modification of Ti3C2Tx with Ce3+ ions to in‐situ form Ce(OH)x‐mediated protective layer, which is beneficial to enabling stable intracellular ...

Conduction abnormalities are restricted to the central nervous system in experimental autoimmune encephalomyelitis induced by inoculation with proteolipid protein but not with myelin basic protein [PDF]

, 1994
Experimental autoimmune encephalomyelitis (EAE) is an inflammatory demyelinating disease of the central nervous system (CNS) and can be induced by inoculation of animals with homogenized CNS tissue or highly purified myelin proteins such as myelin basic ...
