Peripheral nerve injury can lead to great morbidity in those afflicted, ranging from sensory loss, motor loss, chronic pain, or a combination of deficits. Over time, research has investigated neuronal molecular mechanisms implicated in nerve damage, classified nerve injury, and developed surgical techniques for treatment. Despite these advancements, full functional recovery remains less than id...

The incorporation and delivery of neurotrophic factors that stimulate nerve repair in previously developed tunable enzymatically crosslinked silk fibroin-based conduits are presented. In article number 2000753 by Joaquim M. Oliveira co-workers, glial cell line-derived factor (GDNF), acting upon motor sensory neurons, also instigating angiogenesis, uses these as a platform for its controlled del...

The desert hedgehog (Dhh) signaling pathway is involved in the development of peripheral nerves (PNs). Dhh-null mice show abnormal neuronal development and perineurial barrier function. As it was previously shown that dhh is mainly expressed in developmental nerves and Sonic hedgehog protein (dhh homologous) has therapeutic effects in neuronal survival, we attempted to investigate the possible ...

Serotonin exerts a wide range of physiological actions on many different lobster tissues. To begin the examination of the role of serotonin in lobsters at a cellular level, we have used immunohistochemical methods to search for presumptive serotonergic neurons, their central and peripheral projections, and their terminal fields of arborization. Whole mount preparations of the ventral nerve cord...

Peripheral nerve defects, but not artificial nerves, are repaired by endogenous cells. We examined cell activity during the repair process in the presence of autologous nerves and artificial preparations in order to guide future artificial nerve fabrication. PLGA tubes, nerve scaffolds comprising a PLGA tube plus 6,000 fibroin fibers, or autologous nerves were implanted into 10 mm rat sciatic n...

petrous apex lesions of temporal bone progress slowly. most of the time not only destruct this area but also involve neighbouring element. the symptoms of the neighbouring neuro-vasculare involvement we can recognize these lesions. the most common symptoms of involvement of the petrous apex are: headache, conductive hearing loss or sensorineural type, paresthesia and anesthesia of the trigemina...

An important strategy in neural tissue engineering involves imparting electrical properties to the regenerative template encourage cell proliferation and differentiation. Several clinical studies have confirmed that direct or indirect stimulation therapy greatly impacts treatment of peripheral central nerve injury. Nerve regeneration can be accelerated by application stimulations different meth...

We hypothesized that a chemically extracted acellular allogeneic nerve graft used in combination with bone marrow mesenchymal stem cell transplantation would be an effective treatment for long-segment sciatic nerve defects. To test this, we established rabbit models of 30 mm sciatic nerve defects, and treated them using either an autograft or a chemically decellularized allogeneic nerve graft w...
