During herpes simplex virus latency, transcripts accumulate from a single transcription unit of the viral genome. The promoter for these latency-associated transcripts (LAT) has been located, and a number of studies have documented the specific regions of this promoter which are important in transient assays of neuronal cells in culture. To examine the regulation of this promoter from the viral...

Background: Long-term microgravity in spaceflight has been demonstrated with induction of multi-organ damage and dysfunction, including the dorsal root ganglia (DRG) injury. Present studies investigated protective effects oral pyruvate drinking water on lumbar 5 (L5) DRG tissues rats subjected hindlimb unweighting (HU). Methods: Sprague-Dawley male were randomly divided into four groups (N = 10...

The distribution of P2X1, P2X2, P2X3, P2X4, P2X5 and P2X6 receptors, a family of ATP-gated cation channels, in rat trigeminal, dorsal root, nodose, superior cervical, and coeliac ganglia was studied immunohistochemically. It was found that polyclonal antibodies for the six P2X receptor subtypes could label over 90% of neurones in these ganglia to different intensities. There was also considerab...

Chronic pain following lower-limb amputation is now a well-known neuropathic, chronic-pain syndrome that usually presents as a combination of phantom and stump pain. Controlling these types of neuropathic pain is always complicated and challenging. If pharmacotherapy does not control the patient's pain, interventional procedures have to be taken. The aim of this study was to evaluate the effica...

OBJECTIVE To investigate abnormal prion protein (PrP) deposition in the peripheral nervous system (PNS) in human prion diseases. METHODS Eight patients with prion diseases were examined: three with sporadic Creutzfeldt-Jakob disease (sCJD), two with dural graft associated CJD (dCJD), one with Gerstmann-Straussler-Scheinker disease (GSS) with a PrP P102L mutation (GSS102), and two with a P105L...
