The phagocytic ability of the pigment epithelium after optic nerve sectioning and tectal removal was investigated in the goldfish by the method of ingestion of latex beads. 4 days after sectioning, an increase in latex beads was evident which decreased by the end of the first week. Tectal removal also triggered increase intake of latex beads which was(More)
The regulation of gene expression in the brain reward regions is known to contribute to the pathogenesis and persistence of drug addiction. Increasing evidence suggests that the regulation of gene transcription is mediated by epigenetic mechanisms that alter the chromatin structure at specific gene promoters. To better understand the involvement of(More)
In order to substantiate the concept that cocaine behavioral effects may be influenced by histone modification, rats were trained to self-administer cocaine intravenously (0.75 mg/(kginjection)), and were systemically pretreated with sodium butyrate (NaBu), a potent histone deacetylase inhibitor, before the test session during the maintenance phase. The(More)
The development of the retina of the albino rat was studied after sectioning of the optic nerves on the 2nd postnatal day. The 2nd day represents a stage at which the retina shows only the ganglion cell layer clearly delineated from an undifferentiated mass. Section of optic nerves at this stage did not affect the subsequent retinal development. Both(More)
We investigated the role of histone H3 phosphoacetylation in the nucleus accumbens (NAc) in heroin-conditioned place preference paradigm. Heroin could dose-dependently increase histone H3 phosphoacetylation specifically in the NAc and could enhance heroin place preference. Injection of trichostatin A into the NAc significantly augmented heroin-induced(More)
The protein LMO3 belongs to the LIM only (LMO) group of transcriptional regulators, which act as molecular adaptors for protein-protein interactions. However, little is known about its interactive proteins and functions. Evaluating LMO3 in a yeast two-hybrid screen, we identified the calcium- and integrin-binding protein CIB as an LMO3-binding protein,(More)
Impaired inflammatory functions may be critical factors in the mechanisms of severe CNS disorders classified as the human immunodeficiency virus-1 (HIV-1)-associated dementia (HAD). Evidence indicates that a viral gene product, the transactivator of transcription protein (Tat), can markedly contribute to these events. We herein report that sulfated(More)
Human immunodeficiency virus (HIV)-1 infection of the central nervous system occurs in the vast majority of HIV-infected patients. HIV-associated dementia (HAD) represents the most severe form of HIV-related neuropsychiatric impairment. The pathogenesis of HAD is mediated by disruption of neuronal cell signal pathways, which ultimately triggers neuronal(More)
A novel and simple electroless Ni–Cu–P plating process was used for preparing corrosion-resistant and electromagnetic interference shielding wood-based composite. The effects of CuSO4·5H2O concentration, pH value in the plating solution and operation temperature on the metal deposition, surface resistivity, chemical composition, corrosion resistance and(More)
Several lines of evidence suggest the non-cholinergic functions of acetylcholinesterase (AChE) in promoting neurite outgrowth of cultured neurons and in inducing the postsynaptic specializations of developing neuromuscular junctions. In order to support the hypothesis, a cholinergic synapse-forming cell line NG108-15 was over-expressed with chick AChE by(More)
