Fluorimetric and CD Recognition between Various ds-DNA/RNA Depends on a Cyanine Connectivity in Cyanine-guanidiniocarbonyl-pyrrole Conjugate

Molecules, 2020
Two novel isosteric conjugates of guanidiniocarbonyl-pyrrole and 6-bromo-TO (thiazole orange) were prepared, differing only in linker connectivity to cyanine (benzothiazole nitrogen vs. quinoline nitrogen).

Macromolecule‐Driven Supramolecular Polymerization Induced by Crowding Effects

Angewandte Chemie International Edition, Accepted Article.
Macromolecular crowding plays a crucial role in biological systems by regulating dynamic processes, yet its effects in fully synthetic environments remain largely unexplored. Here, we systematically investigate how excluded volume effects influence supramolecular polymerizations in organic media.

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).

Randomised, double-blind comparison of a fixed co-formulation of intra-articular polynucleotides and hyaluronic acid versus hyaluronic acid alone in the treatment of knee osteoarthritis: two-year follow-up

BMC Musculoskeletal Disorders, 2021
Background A first-year interim analysis of this two-year study suggested that intra-articular injections of highly purified, natural-origin polynucleotides and hyaluronic acid (HA) as a fixed combination (PNHA) might improve knee function and joint pain

Analytical Study of Lanolin as Potential Biomarker of Prehistoric Sheep‐Shearing Practice

Chemistry–Methods, EarlyView.
Lanolin, a complex wax found on sheep wool, accumulates on shearing tools, such as flint and obsidian blades, used since the Neolithic. This study explores lanolin's degradation patterns as a potential biomarker for prehistoric sheep‐shearing practices, employing micro‐Fourier transformed infrared spectroscopy, hyperspectral imaging, and gas ...

Ribozyme Activity of RNA Nonenzymatically Polymerized from 3′,5′-Cyclic GMP

Entropy, 2013
3′,5′-Cyclic GMP spontaneously nonenzymatically polymerizes in a base-catalyzed reaction affording G oligonucleotides. When reacted with fully or partially sequence-complementary RNA (oligo C), the abiotically generated oligo G RNA displays a typical ...
