In contrast to the pharmacological studies implicating delta-opioid receptor subtypes, cloning studies have identified only a single cDNA encoding a delta receptor, DOR-1. Antisense studies have established the importance of DOR-1 in delta analgesia in mice. Antisense mapping extends this approach to include oligodeoxynucleotides which are targeted against(More)
The rat spinal cord reveals a complex pattern of zinc-enriched (ZEN) boutons. As a result of in vivo exposure to selenide ions, nanosized clusters of zinc selenide are created in places where zinc ions are present, including the zinc-containing synaptic vesicles of ZEN boutons. The clusters can be silver enhanced by autometallographic (AMG) development. A(More)
This study aims to address if phosphorylation of the transcription factor c-Jun is associated with lesion-induced death of spinal motoneurons, and if this cellular response is modulated by glial-cell-line-derived neurotrophic factor (GDNF). We found that after both distal axotomy and root avulsion, spinal motoneurons in neonatal rats expressed(More)
The physiological sequelae of undernutrition were investigated in rats that were undernourished from day 1-21 and subsequently free-fed to 75 days of age. Population responses were recorded in the corticospinal tract following surface stimulation of the motor cortex, which activates corticospinal cells directly, and also indirectly via cortical synapses.(More)
The failure of axonal regeneration in the mammalian central nervous system (CNS) is currently attributed to the glial environment of the lesion site which elaborates a multitude of inhibitory factors. Less attention has been paid to the potential of trophic support associated with the CNS, especially in relation to the status of the damaged CNS after an(More)
Objective: To perform a Meta-analysis on hepatitis B surface antigen (HBsAg)-positive rates among general Chinese population aged 1-59 years. Methods: We systemically reviewed the related data (January 2007 to August 2016) published from Chinese National Knowledge Infrastructure (CNKI), VIP, and PubMed. We also assessed the HBsAg-positive rates among(More)
