We have shown previously that a peptide, MPG, derived from the hydrophobic fusion peptide of HIV-1 gp41 and the hydrophilic nuclear localisation sequence of SV40 large T antigen, can be used as a powerful tool for the delivery of oligonucleotides into cultured cells. Now we extend the potential of MPG to the delivery of nucleic acids into cultured cells. In vitro, MPG interacts strongly with nu...

INTRODUCTION The vasa nervorum comprises a network of small diameter blood vessels that provide blood supply to nerves and ganglia. The cell bodies of autonomic nerves innervating the urogenital organs are housed in the major pelvic ganglia (MPG) in rats. The vasa nervorum of rat MPG have not been characterized previously, and it is not known whether these blood vessels are innervated by neuron...

background: the poor permeability of the plasma and nuclear membranes to dna plasmids are two major barriers for the development of these therapeutic molecules. therefore, success in gene therapy approaches depends on the development of efficient and safe non-viral delivery systems. objectives: the aim of this study was to investigate the in vitro delivery of plasmid dna encoding hpv16 e7 gene ...

We discuss the application of heterogeneous metaprogramming (MPG) for the interfacebased design, which deals with the synthesis of the communication interfaces between Intellectual Property components (IPs). Heterogeneous MPG is based on the simultaneous usage of a domain language for describing domain functionality and a metalanguage for developing generic components and program generators. We...

Generation of reactive oxygen species plays a pivotal role in the development of cardiovascular diseases. The present study describes the effects of the methanolic extract of Phoebe grandis (MPG) stem bark on reactive oxygen species-induced endothelial dysfunction in vitro. Endothelium-dependent (acetylcholine, ACh) and -independent relaxation (sodium nitroprusside, SNP) was investigated from i...

Previous studies indicate that overexpression of N-methylpurine DNA glycosylase (MPG) dramatically sensitizes cells to alkylating agent-induced cytotoxicity. We recently demonstrated that this sensitivity is preceded by an increased production of AP sites and strand breaks, confirming that overexpression of MPG disrupts normal base excision repair and causes cell death through overproduction of...

Large surfaces such as tabletop and whiteboard displays naturally afford collocated collaboration, where multiple people work together over the shared workspace. As large digital displays become more ubiquitous, it becomes increasingly important to examine their role in supporting groups of distributed collaborators working over the digital work surface. In particular, Mixed Presence Groupware ...

UNLABELLED Alkylating agents are a first-line therapy for the treatment of several aggressive cancers, including pediatric glioblastoma, a lethal tumor in children. Unfortunately, many tumors are resistant to this therapy. We sought to identify ways of sensitizing tumor cells to alkylating agents while leaving normal cells unharmed, increasing therapeutic response while minimizing toxicity. Usi...

A simple spectrophotometric method for the determination of N-acetyl-L-cysteine (NAC) and N-(2-mercaptopropionyl)glycine (MPG) in pharmaceutical preparations was developed, validated, and used. The proposed equilibrium method is based on a coupled two-step redox and complexation reaction. In the first step, Fe(III) is reduced to Fe(II) by NAC or MPG. Subsequently, Fe(II) is complexed with 2,4,6...

Introduction. We are presenting a rare case of a patient who developed simultaneous tumors in the main parotid gland (MPG) and an accessory parotid gland (APG). The APG tumor was not recognized when the more prominent MPG tumor was excised. We will discuss the clinical features of this case. Case presentation. A 66-year-old woman was referred to our department with a painless right cheek mass. ...
