Biologically‐oriented alveolar ridge preservation to correct bone dehiscence at immediate implant placement

Clinical Advances in Periodontics, EarlyView.
Abstract Background The purpose of the present case study is to describe the application of a modification of the Biologically‐oriented Alveolar Ridge Preservation (BARP) principles in cases of peri‐implant bone dehiscence (PIBD) due to a compromised alveolus at immediate implant placement (IIP).

Electronic signature of DNA nucleotides via transverse transport

, 2004
We report theoretical studies of charge transport in single-stranded DNA in the direction perpendicular to the backbone axis. We find that, if the electrodes which sandwich the DNA have the appropriate spatial width, each nucleotide carries a unique ...

A Michaelis‐Arbuzov‐Type Pathway to a Protected 2ʹ‐Deoxy‐2ʹ‐Selenomethyl‐Adenosine‐3ʹ,5ʹ‐Phosphoroselenolate Guanosine Dinucleotide for Use in Modified m7G Cap Synthesis

Chemistry – A European Journal, EarlyView.
Here we report a synthesis of the dinucleotide 4 for a projected future total synthesis of the m7G cap 1. Highlights of the route include: 1) a 3ʹ‐H‐phosphonate/5ʹ‐selenocyanate Michaelis‐Arbuzov coupling to forge the 3ʹ,5ʹ‐phosphoroselenolate; 2) an Amosova reductive selenomethylation to install the 2ʹ‐SeMe; 3) a solid CPR II 5ʹ‐O‐phosphitylation; and

Nucleotides: Structure and Properties [PDF]

, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...

Evolved DNAzymes and Stable Activation Chemistry Enable High‐Efficiency DNA Ligation

Chemistry – A European Journal, EarlyView.
In vitro selection of pre‐structured DNA libraries and chemical screening of alternative activation groups yielded trans‐acting DNAzymes with faster ligation rates and enhanced DNA substrate stability. The combination of C3S1 DNAzymes and phosphobenzimidazole‐activated DNA substrates provides improved DNA ligation performance, offering promise for ...

DNA strand break repair and neurodegeneration. [PDF]

, 2013
A number of DNA repair disorders are known to cause neurological problems. These disorders can be broadly characterised into early developmental, mid-to-late developmental or progressive.

Highly Potent Fluorogenic Ligands for Triplex DNA: 5‐Substituted 2‐(Naphthalen‐2‐yl)‐4H‐Chromen‐4‐Ones

Chemistry – A European Journal, EarlyView.
5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Presence of a classical RRM-fold palm domain in Thg1-type 3'- 5'nucleic acid polymerases and the origin of the GGDEF and CRISPR polymerase domains

Biology Direct, 2010
Background Almost all known nucleic acid polymerases catalyze 5'-3' polymerization by mediating the attack on an incoming nucleotide 5' triphosphate by the 3'OH from the growing polynucleotide chain in a template dependent or independent manner. The only
