Triplex forming oligonucleotide DNA triple helices offer new perspectives towards oligonucleotide-directed gene regulation. Triple helix forming oligonucleotides, which bind to double-stranded DNA, are of special interest since they are targeted to the gene itself rather than to its mRNA product (as in the antisense strategy). However, the poor stability of some of these structures might limit ...

This study highlights the operational and practical advantages of using triplex mud pump systems in favor duplex to optimize drilling capabilities under specific conditions. Additionally, material selection piston subassembly was analyzed simulated parameters SolidWorks determine HNBR over NBR elastomer materials.

In this work, we propose a new approach to constructing interval-based composite indicators based on the triplex representation. So, measure principal value of indicator and simultaneously value's uncertainty due different assumptions as weightings associated how their ranks can vary considering or weights. The is useful not only construction but also for reliable interpretation results. applic...

Many long noncoding RNAs are bound to chromatin. MEG3 binds to multiple different genomic locations, containing GA-rich motifs, and form RNA-DNA triplex structures. In this work, we test whether the MEG3 binding sites are specific enough to be regulated by a particular lncRNA. We show that at least in the case of MEG3, a subset of the triplex target sites (TTS) is able to hybridize with various...

The ease of fragmentation of various charge states of protonated polypropylenamine (POPAM) dendrimers is investigated by surface-induced dissociation. Investigated are the protonated diaminobutane propylenamines [DAB(PA)n] DAB(PA)8 (1+ and 2+), DAB(PA)16 (2+ and 3+), and DAB(PA)32 (3+ and 4+). These ions have been proposed to fragment by charge-directed intramolecular nucleophilic substitution ...

Peptide nucleic acid (PNA) forms sequence-specific (PNA)2/DNA triplexes with one strand of double-stranded DNA by strand invasion. When formed with the template strand of DNA such a (PNA)2/DNA triplex can arrest transcription elongation in vitro and can thus act as an anti-gene agent. One of the major obstacles to applying PNA as an anti-gene agent in vivo is that PNA strand invasion occurs at ...

Mycobacterium triplex was first named in 1996 as an acid-fast bacillus with features that most resemble Mycobacterium simiae and Mycobacterium avium-intracellulare complex but which possesses a distinct mycolic acid pattern as well as a distinctive 16S rRNA hypervariable region. It has been isolated from lymph node, sputum, and cerebrospinal fluid specimens, but to date only rare clinical cases...

A DNA structure is described that can cleave single-stranded DNA oligonucleotides in the presence of ionic copper. This "deoxyribozyme" can self-cleave or can operate as a bimolecular complex that simultaneously makes use of duplex and triplex interactions to bind and cleave separate DNA substrates. Bimolecular deoxyribozyme-mediated strand scission proceeds with a kobs of 0.2 min-1, whereas th...
