Kool chemistry of DNA and RNA biopolymers Biopolymers (IF 1.854) Pub Date : 2021-01-25 Cynthia J. Burrows
About 30 years ago, before the term “chemical biology” was part of our lexicon, a small number of organic chemists recognized that they could apply their skills in synthesis, molecular design and physical characterization to the field of nucleic acid chemistry. Much of this was made easier by Marv Caruther's development of phosphoramidites, which meant that oligonucleotides of DNA and RNA could be

Human calcitonin (hCT) is a 32‐residue peptide hormone that is produced in the thyroid where it regulates blood calcium levels and promotes bone formation. While hCT was previously used to treat bone disorders, this has ceased because hCT has been shown to aggregate when elevated levels of the peptide are either produced naturally or injected, and the resulting amyloid fibrils toxic.

Hydrogel dressings have significant advantages such as absorption of tissue exudate, maintenance of proper moist environment, and promotion of cell proliferation. However, facile preparation method and high‐efficient antibacterial hydrogel dressings are still a great challenge. In this study, a facile approach to prepare antibacterial nanocomposite hydrogel dressing to accelerate healing was explored

Recently, the use of hybrid double network (DN) hydrogels has become prominent due to their enhanced mechanical properties, which has opened the door for new applications of these soft materials. Only a few of these gels have demonstrated both injectable and moldable capabilities. In this work, we report the mechanical properties, gauge factor (GF) values and demonstrate both the injectability and

Combining particle tracking microrheology and viscometry for the study of DNA aqueous solutions. Biopolymers (IF 1.854) Pub Date : 2020-03-30 Evdokia Stefanopoulou,Aristeidis Papagiannopoulos
We use video particle tracking microrheology (VPTMR) in order to investigate the viscoelasticity of salmon DNA and correlate it to its steady‐flow shear‐thinning viscosity. Aqueous solutions of DNA are tested in a wide concentration range from the dilute to the semidilute unentangled concentration regime. The observed mean squared displacement shows power‐law scaling with lag‐time which is equivalent

Modelling energy and charge transfer in DNA is a challenging problem because of the many conformations it can take. Belobo Belobo and Dang Koko use a discrete variational approach to study the charge transfer mechanism in DNA based on the Holstein‐Su‐Schrieffer‐Heeger model. By considering transversal and longitudinal motions in DNA, they show that the charge transfer mechanism may be explained as

Formation of α-synuclein aggregates in aqueous ethylammonium nitrate solutions. Biopolymers (IF 1.854) Pub Date : 2020-03-23 Takahiro Takekiyo,Natsuki Yamada,Chikako T Nakazawa,Taku Amo,Atsushi Asano,Yukihiro Yoshimura
The effect of adding ethylammonium nitrate (EAN), which is an ionic liquid (IL), on the aggregate formation of α‐synuclein (α‐Syn) in aqueous solution has been investigated. FTIR and Raman spectroscopy were used to investigate changes in the secondary structure of α‐Syn and in the states of water molecules and EAN. The results presented here show that the addition of EAN to α‐Syn causes the formation

α-Chitin dissolution, N-deacetylation and valorization in deep eutectic solvents. Biopolymers (IF 1.854) Pub Date : 2020-03-12 Filipa A Vicente,Bojana Bradić,Uroš Novak,Blaž Likozar
Chitin displays a highly rigid structure due to the vast intra‐ and intermolecular hydrogen bonding, thus hindering its dissolution and deacetylation using most solvents. Deep eutectic solvents (DESs) are special and environmentally friendly solvents composed of a hydrogen bond acceptor and a hydrogen bond donor. This allows them to dissolve chitin by disturbing its natural hydrogen bonding while establishing
