The process of axonal regeneration after peripheral nerve injury (PNI) is slow and mostly incomplete. Previous studies have investigated the neuroprotective effects of fibroblast growth factor 10 (FGF10) against spinal cord injury and cerebral ischemia brain injury. However, the role of FGF10 in peripheral nerve regeneration remains unknown. In this study, we aimed to investigate the underlying therapeutic effects of FGF10 on nerve regeneration and functional recovery after PNI and to explore the associated mechanism. Our results showed that FGF10 administration promoted axonal regeneration and functional recovery after nerve damage. Moreover, exogenous FGF10 treatment also prevented SCs from excessive oxidative stress-induced apoptosis, which was probably related to the activation of phosphatidylinositol-3 kinase/protein kinase B (PI3K/Akt) signaling. The inhibition of the PI3K/Akt pathway by the specific inhibitor LY294002 partially reversed the therapeutic effects of FGF10 both and . Thus, from our perspective, FGF10 may be a promising therapeutic drug for repairing sciatic nerve damage through countering excessive oxidative stress-induced SC apoptosis.

Wearable devices designed for the somatosensory system aim to provide event-cue feedback electronics and therapeutic stimulation to the peripheral nervous system. This prompts a neurological response that is relayed back to the central nervous system. Unlike virtual reality tools, these devices precisely target peripheral mechanoreceptors by administering specific stimuli.

NF2-related schwannomatosis, previously known as neurofibromatosis type 2, is a genetic disorder characterized by nerve tumors due to gene mutations. Mice with deletion develop schwannomas slowly with low penetrance, hence inconvenient for preclinical studies. Here, we show that NF2, by recruiting E3 ubiquitin ligases β-TrCP1/2, promotes WWC1-3 ubiquitination and degradation.

From the Departments of Gynecology and Obstetrics.
Importance: Patients deciding between advanced therapies for overactive bladder syndrome may be interested to know the likelihood of treatment crossover after sacral neuromodulation, intradetrusor OnabotulinumtoxinA, or percutaneous tibial nerve stimulation. Treatment crossover was defined as a switch from one advanced therapy to another.
Objectives: The aim of this study was to estimate the rate of treatment crossover after each advanced therapy for nonneurogenic overactive bladder syndrome.

Peptide nanofibers have been attractive targets for regenerative medicine applications due to their tailorability to be easily functionalized for specific bioactivity, biocompatibility, ease of synthesis, adjustability of their physicochemical characteristics, and lack of biological contamination. Research groups have investigated their use for the regeneration of various tissues, such as bone, cartilage, brain, peripheral nerves, cardiac tissue, vascular tissues, endocrine cells, muscles, etc., for the treatment of degenerative diseases or tissue loss due to accidents or aging.

Introduction: Quantitative neuromorphometry analysis of the peripheral nerve is paramount to nerve regeneration research. However, this technique relies upon accurate segmentation and determination of myelin and axonal area. Manual histological analysis methods are time- consuming, and subject to error and bias.
