Renal sympathetic denervation (RDNx) has emerged as a novel therapy for hypertension; however, the therapeutic mechanisms remain unclear. Efferent renal sympathetic nerve activity has recently been implicated in trafficking renal inflammatory immune cells and inflammatory chemokine and cytokine release. Several of these inflammatory mediators are known to activate or sensitize afferent nerves. ...

The action of insulin in the central nervous system produces sympathetic nervous system activation (also called sympathoactivation), although the neuronal intracellular mechanisms that mediate this are unclear. We hypothesized that PI3K and MAPK, the major pathways involved in insulin receptor signaling, mediate sympathetic nerve responses to insulin. Intracerebroventricular administration of i...

Background: Nerve recovery after a complex trauma is affected by many factors and poorly vascularized bed often the cause of failure perineural scar. Many techniques have been devised to avoid this problem possibility transfer nerve with surrounding viable sliding tissue could help in purpose; Methods: We performed an anatomic study on 8 injected specimens investigate raise medial sural artery ...

Schwannoma is a benign encapsulated nerve sheath tumor composed of Schwann cells, that may arise anywhere along the course nerve. Cutaneous schwannomas, associated with peripheral nerves, usually present as slow-growing well-circumscribed nodule, localized in dermis or subcutaneous tissue. They are generally asymptomatic; however, they become painful by nervous compression. Since clinical signs...

Injury to peripheral nerves often results in a persistent neuropathic pain condition that is characterized by spontaneous pain, allodynia, and hyperalgesia. Nerve injury is accompanied by a local inflammatory reaction in which nerve-associated and immune cells release several pronociceptive mediators. Kinin B1 receptors are rarely expressed in nontraumatized tissues, but they can be expressed a...

Heart rate variability (HRV) is a measure of the balance between sympathetic mediators of heart rate that is the effect of epinephrine and norepinephrine released from sympathetic nerve fibres acting on the sino-atrial and atrio-ventricular nodes which increase the rate of cardiac contraction and facilitate conduction at the atrio-ventricular node and parasympathetic mediators of heart rate tha...

The aim of this review is to report recent findings and ongoing studies on the effects of acupuncture on endogenous biological mediators, in particular on neurotrophins such as nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF). Acupuncture is a therapeutic technique and is a part of Traditional Chinese Medicine (TCM). Western descriptions of the clinical efficacy of acupunc...

Many axotomized myelinated as well as unmyelinated cutaneous nerve fibers are sensitive to mechanical stimuli applied to the cut nerve end within a few hours after nerve lesion. Here we investigated the influence of inflammatory mediators on this ectopic mechanosensitivity after cutting and ligating the sural nerve in anesthetized rats. Neural activity was recorded from single axons in filament...
