The 5-oxyacetic acid modification destabilizes double helical stem structures and favors anionic Watson-Crick like cmo5U-G base pairs.

: Watson-Crick like G-U mismatches with tautomeric Genol or Uenol bases can evade fidelity checkpoints and thereby contribute to translational errors. The 5-oxyacetic acid uridine (cmo5U) modification is a base modification at the wobble position on tRNAs and is presumed to expand the decoding capability of tRNA at this position by forming Watson-Crick like cmo5Uenol-G mismatches. A detailed investigation on the influence of the cmo5U modification on structural and dynamic features of RNA was carried out us...

Does the Watson-Jones or Modified Smith-Petersen Approach Provide Superior Exposure for Femoral Neck Fracture Fixation?

A well-reduced femoral neck fracture is more likely to heal than a poorly reduced one, and increasing the quality of the surgical exposure makes it easier to achieve anatomic fracture reduction. Two open approaches are in common use for femoral neck fractures, the modified Smith-Petersen and Watson-Jones; however, to our knowledge, the quality of exposure of the femoral neck exposure provided by each approach has not been investigated.

Novel pathway for mutagenic tautomerization of classical А∙Т DNA base pairs via sequential proton transfer through quasi-orthogonal transition states: A QM/QTAIM investigation.

In this paper we have theoretically predicted a novel pathway for the mutagenic tautomerization of the classical A∙T DNA base pairs in the free state, the Watson-Crick A·Т(WC), reverse Watson-Crick A·Т(rWC), Hoogsteen A·Т(H) and reverse Hoogsteen A·Т(rH) pairs, via sequential proton transfer accompanied by a significant change in the mutual orientation of the bases. Quantum-mechanical (QM) calculations were performed at the MP2/aug-cc-pVDZ//B3LYP/6-311++G(d,p) level in vacuum phase, along with Bad...

Molecular dynamics analysis of stabilities of the telomeric Watson-Crick duplex and the associated i-motif as a function of pH and temperature.

This work deals with a molecular dynamics analysis of the protonated and deprotonated states of the natural sequence d[(CCCTAA)CCCT] of the telomeric DNA forming the intercalated i-motif or paired with the sequence d[(CCCTAA)CCCT] and forming the Watson-Crick (WC) duplex. By utilizing the amber force field for nucleic acids we built the i-motif and the WC duplex either with native cytosines or using their protonated forms. We studied, by applying molecular dynamics simulations, the role of hydrogen bonds be...

What is real success in nursing research?

Who and what can define what success is in research? With the United Kingdom's seven-yearly Research Excellence Framework and recent anniversaries such as the 40 of the Journal of Advanced Nursing providing an opportunity to look back and assess progress made and successes achieved. But how much do we do this as individual researchers?. Research success in nursing occurs mostly in a small disciplinary goldfish bowl. While the profession has progressed in terms of the number of journals, professors and volum...

No-Go Theorem for Nonstandard Explanations of the τ→K_{S}πν_{τ} CP Asymmetry.

The CP asymmetry in τ→K_{S}πν_{τ}, as measured by the BABAR collaboration, differs from the standard model prediction by 2.8σ. Most nonstandard interactions do not allow for the required strong phase needed to produce a nonvanishing CP asymmetry, leaving only new tensor interactions as a possible mechanism. We demonstrate that, contrary to previous assumptions in the literature, the crucial interference between vector and tensor phases is suppressed by at least 2 orders of magnitude due to Watson's f...

X-ray crystal structures show DNA stacking advantage of terminal nitrile substitution in Ru-dppz complexes.

The new complexes [Ru(TAP)2(11-CN-dppz]2+ [Ru(TAP)2(11-Br-dppz]2+and [Ru(TAP)2(11,12-CN2-dppz)]2+ are reported. The addition of nitrile substituents to the dppz ligand of the DNA photooxidising complex [Ru(TAP)2(dppz)]2+ promotes π-stacking interactions and ordered binding to DNA, as shown by X-ray crystallography. The structure of lambda-[Ru(TAP)2(11-CN-dppz)]2+ with the DNA duplex d(TCGGCGCCGA)2 shows, for the first time with this class of complex, a closed intercalation cavity with an AT base pair at th...

Above and Beyond Watson and Crick: Guanine Quadruplex Structures and Microbes.

Advances in understanding mechanisms of nucleic acids have revolutionized molecular biology and medicine, but understanding of nontraditional nucleic acid conformations is less developed. The guanine quadruplex (G4) alternative DNA structure was first described in the 1960s, but the existence of G4 structures (G4-S) and their participation in myriads of biological functions are still underappreciated. Despite many tools to study G4s and many examples of roles for G4s in eukaryotic molecular processes and is...

RNA-Targeted Therapeutics.

RNA-targeted therapies represent a platform for drug discovery involving chemically modified oligonucleotides, a wide range of cellular RNAs, and a novel target-binding motif, Watson-Crick base pairing. Numerous hurdles considered by many to be impassable have been overcome. Today, four RNA-targeted therapies are approved for commercial use for indications as diverse as Spinal Muscular Atrophy (SMA) and reduction of low-density lipoprotein cholesterol (LDL-C) and by routes of administration including subcut...

Factors Affecting the Tailing of Blunt End DNA with Fluorescent Pyrimidine dNTPs.

The transferase activity of non-proofreading DNA polymerases is a well-known phenomenon that has been utilized in cloning and sequencing applications. The non-templated addition of modified nucleotides at DNA blunt ends is a potentially useful feature of DNA polymerases that can be used for selective transformation of DNA 3' ends. In this paper, we characterized the tailing reaction at perfectly matched and mismatched duplex ends with Cy3- and Cy5-modified pyrimidine nucleotides. It was shown that the best ...

Therefore, it is of great interest to achieve sensitive, rapid and simple detection methods. It is believed that nucleic acids assays, especially aptamers, are very important in modern life sciences for target detection and biological analysis. Aptamers and DNA-based sensors have been widely used for the design...

Surprising Sequence Effects on GU Closure of Symmetric 2 × 2 Nucleotide RNA Internal Loops.

GU base pairs are important RNA structural motifs and often close loops. Accurate prediction of RNA structures relies upon understanding the interactions determining structure. The thermodynamics of some 2 × 2 nucleotide internal loops closed by GU pairs are not well understood. Here, several self-complementary oligonucleotide sequences expected to form duplexes with 2 × 2 nucleotide internal loops closed by GU pairs were investigated. Surprisingly, nuclear magnetic resonance revealed that many of the seq...

Optimal destabilization of DNA double strands by single-nucleobase caging.

Photolabile protecting groups are widely used to trigger oligonucleotide activity. The ON/OFF-amplitude is a critical parameter. We have developed an experimental setup to identify protecting group derivatives with superior caging properties. Bulky rests are attached to the cage moiety via Cu-catalyzed azide-alkyne cycloaddition post-synthetically on DNA. Interestingly, we found that the decrease in melting temperature upon introducing o-nitrobenzyl-caged (NPBY-) and diethylaminocoumarin-cages (DEACM-) in D...

Enhanced Bacterial Immunity and Mammalian Genome Editing via RNA-Polymerase-Mediated Dislodging of Cas9 from Double-Strand DNA Breaks.

The ability to target the Cas9 nuclease to DNA sequences via Watson-Crick base pairing with a single guide RNA (sgRNA) has provided a dynamic tool for genome editing and an essential component of adaptive immune systems in bacteria. After generating a double-stranded break (DSB), Cas9 remains stably bound to DNA. Here, we show persistent Cas9 binding blocks access to the DSB by repair enzymes, reducing genome editing efficiency. Cas9 can be dislodged by translocating RNA polymerases, but only if the polymer...

On the basis of potential energy surfaces, reaction Gibbs energies, equilibrium constants, imaginary frequencies, forward and reverse barrier heights, tunneling-corrected rate constants, half-lives of the forward and reverse reactions, percent tautomerization, and Boltzmann dist...

Determination of the size distribution of non-spherical nanoparticles by electric birefringence-based methods.

The in situ determination of the size distribution of dispersed non-spherical nanoparticles is an essential characterization tool for the investigation and use of colloidal suspensions. In this work, we test a size characterization method based on the measurement of the transient behaviour of the birefringence induced in the dispersions by pulsed electric fields. The specific shape of such relaxations depends on the distribution of the rotational diffusion coefficient of the suspended particles. We analyse ...
