Temperature dependence of Raman vibrational bandwidths in poly(rA) and rAMP [PDF]

, 1993
Isotropic and anisotropic spontaneous Raman spectra were obtained from solutions of poly(ra) and rAMP in buffer. The temperature dependence of these spectra was measured to elucidate the influence of macromolecular dynamics and solvent dynamics on the ...

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).

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).

Advances in Fabricating the Electrospun Biopolymer-Based Biomaterials

Journal of Functional Biomaterials, 2021
Biopolymers formed into a fibrous morphology through electrospinning are of increasing interest in the field of biomedicine due to their intrinsic biocompatibility and biodegradability and their ability to be biomimetic to various fibrous structures ...

Localisation of the human hSuv3p helicase in the mitochondrial matrix and its preferential unwinding of dsDNA [PDF]

, 2002
We characterised the human hSuv3p protein belonging to the family of NTPases/helicases. In yeast mitochondria the hSUV3 orthologue is a component of the degradosome complex and participates in mtRNA turnover and processing, while in Caenorhabditis ...

Unraveling the Molecular Basis for G‐Quadruplex‐Binders to ALS/FTD‐Associated G4C2 Repeats of the C9orf72 Gene

ChemBioChem, EarlyView.
Some neurodegenerative disorders can be driven by recurrent mutations in the C9orf72 gene. These sequences can fold into G‐quadruplex secondary structures. Here, by performing in silico investigations coupled with FRET DNA melting assays, we unraveled the molecular basis for the selectivity of a series of organic and organometallic C9orf72 G4‐binders ...

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

Complex Formation Between Polyelectrolytes and Ionic Surfactants [PDF]

, 1998
The interaction between polyelectrolyte and ionic surfactant is of great importance in different areas of chemistry and biology. In this paper we present a theory of polyelectrolyte ionic-surfactant solutions. The new theory successfully explains the cooperative transition observed experimentally, in which the condensed counterions are replaced by ...

Emerging Technologies for Timely Point‐of‐Care Diagnostics of Skin Cancer

Global Challenges, EarlyView.
With the global incidence of skin cancer on the rise and a persistent lack of rapid, noninvasive and sensitive point‐of‐care diagnostic platforms, current and emerging technologies are critically reviewed. Among these, the emerging Raman spectroscopy system is identified as a promising complementary to conventional costly and invasive methods, offering

Mg2+ ion effect on stability of double-stranded popynucleotide formed by polyriboinosinic and polyribocytidilic chains [PDF]

Biophysical Bulletin, 2, 68, 2005 (in russian), 2020
Mg2+ effect on the thermal stability of the double-stranded polynucleotide polyIpolyC (IC) under conditions close to physiological ones (0.1M Na+, pH7) was studied by the differential UV spectroscopy. The initial increase of the ion concentration ([Mg2+]) leads to the increase of the melting temperature (Tm) and to the decrease of the absorption ...
