The isolation of nucleophilic boron bases has led to a paradigm shift in boron chemistry. Previous studies of the bis(carbene) borylene complexes revealed that these compounds possess strong donor abilities, and their reaction inertness is due to the large steric hindrance between boron reagents and reactant. In the present study, we have theoretically studied the [(N)BX] and [(N)BX] compounds (X = H, F, Cl, Br).

Doxorubicin (DOX) is a widely used chemotherapeutic agent known for intercalating into DNA. However, the exact modes of DOX interactions with various DNA structures remain unclear. Using molecular dynamics (MD) simulations, we explored DOX interactions with DNA duplexes (dsDNA), G-quadruplex, and nucleosome.

Identification and analysis of repetitive elements (motifs) in DNA, RNA, and protein macromolecules is an important step in studying structure and functions of these biopolymers. Functional role of NA-BSE (non-adjacent base-stacking element, a widespread tertiary structure motif in various RNAs) in RNA-RNA interactions at various stages of the ribosome function during translation has been investigated in this work. Motifs of this type have been described to date that are reversibly formed during mRNA decoding, moving of the ribosome subunits relative to each other, and moving mRNA and tRNA along the ribosome during translocation.

Objective: To understand perceptions of the clinical practice training program setting for Master of Nursing Specialist postgraduates in anesthesia from the dual perspectives of faculty and students.
Design: A qualitative descriptive study.
Evaluation of Five Ready-to-Use Bases for the Topical Administration of Propranolol Hydrochloride to Treat Infantile Hemangioma.

: Since 2008, following clinical studies conducted on children that revealed the ability of the β-adrenergic antagonist propranolol to inhibit capillary growth in infantile hemangiomas (IHs), its oral administration has become the first-line treatment for IHs. Although oral propranolol therapy at a dosage of 3 mg/kg/die is effective, it can cause systemic adverse reactions. This therapy is not necessarily applicable to all patients.
