which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Drug dependence is a chronic and often recurrent disorder which is associated with many problems such as AIDS, hepatitis, etc. This disorder requires treatment management over time. Methadone maintenance therapy is one addiction treatment method which prevents not only the...

Paraquat (PQ) is a well-known herbicide that exerts its effects by elevating intracellular levels of superoxide. It has been previously demonstrated that oxidative and nitrosative stress participate to PQ-induced cell death. Here, we document that PQ increases the levels of nitric oxide (NO) in rat mesencephalic cells and causes nuclear translocation of glyceraldehyde-3-phosphate dehydrogenase ...

Synaptophysin (SYP) is a synaptic vesicle membrane protein and involved in the release of neurotransmitters, synaptic plasticity, and formation and recycling of synaptic vesicles. SYP may serve as a specific marker of synaptic proteins. Our results showed high glucose and hypoxia could significantly impair the intelligence and the SYP level was positively related to the degree of intelligence i...

GAPDH is a conserved enzyme that binds diverse proteins, such as Siah during apoptotic nuclear translocation. There is one somatic GAPDH gene, but over 60 pseudogenes, the expression of which is nebulous. A single nucleotide polymorphism (SNP) in the GAPDHP44 pseudogene exhibits a beneficial allele in AD. The objective of this study was to examine the P44 gene and to propose a mechanism for the...

The DNA of Serratia marcescens has N6-adenine methylation in GATC sequences. Among 2-aminopurine-sensitive mutants isolated from S. marcescens Sr41, one was identified which lacked GATC methylation. The mutant showed up to 30-fold increased spontaneous mutability and enhanced mutability after treatment with 2-aminopurine, ethyl methanesulfonate, or UV light. The gene (dam) coding for the adenin...

The objective of this study was to evaluate the opinions and attitudes of dentists toward the use of rubber dam during various restorative procedures in their dental practices. A structured questionnaire was designed, and distributed to 300 dentists and those that were fully completed were collected for analysis. The collected informations about the opinions and attitudes of dentists toward the...

BACKGROUND Dams are important to ensure food security and promote economic development in sub-Saharan Africa. However, a poor understanding of the negative public health consequences from issues such as malaria could affect their intended advantages. This study aims to compare the malaria situation across elevation and proximity to dams. Such information may contribute to better understand how ...

Microsoft SharePoint as a Digital Asset Management (DAM) System Harry Hurt Graphic Communication Department, June, 2010 Advisor: Dr. Harvey Levenson The purpose of this study is to determine to what degree Microsoft SharePoint can be used as a digital asset management (DAM) system. DAM systems are utilized to manage the creation, storage, utilization, and distribution of digital rich media file...

DNA adenine methylase (Dam(-)) mutants of Salmonella enterica serovar Typhimurium contain reduced levels of FinP RNA encoded on the virulence plasmid. Dam methylation appears to regulate finP transcription, rather than FinP RNA stability or turnover. The finP promoter includes canonical -10 and -35 modules and depends on the sigma(70) factor. Regulation of finP transcription by Dam methylation ...

Dam, the most described bacterial DNA-methyltransferase, is widespread in gamma-proteobacteria. Dam DNA methylation can play a role in various genes expression and is involved in pathogenicity of several bacterial species. The purpose of this study was to determine the role played by the dam ortholog identified in the entomopathogenic bacterium Photorhabdus luminescens. Complementation assays o...
