A search of the Cambridge Structural Database (CSD) was carried out for phosphine-water and arsine-water complexes in which water is either the proton donor in hydrogen-bonded complexes, or the electron-pair donor in pnicogen-bonded complexes. The range of experimental P-O distances in the phosphine complexes is consistent with the results of ab initio MP2/aug’-cc-pVTZ calculations carried out ...

Polycationic brushes are attractive systems for the design of nanomaterials gene delivery as they enable rational their architecture with a broad range grafting densities, thicknesses, and chemistries. Recently, performance siRNA is highlighted strong impact molecular on RNA binding transfection efficiency now calls greater understanding polymer brush-oligonucleotide complexes. In this study, m...

Proteins involved in interactions throughout the course of evolution tend to co-evolve and compensatory changes may occur interacting proteins maintain or refine such interactions. However, certain residue pair alterations prove be detrimental for functional Hence, determining co-evolutionary pairings that could structurally functionally relevant maintaining conservation an inter-protein intera...

We investigate the problem when tensor functor by a bimodule yields singular equivalence. It turns out that this is equivalent to one Hom given same induces triangle equivalence between homotopy categories of acyclic complexes injective modules. give conditions on appears in pair bimodules, defines with level. construct an explicit combinatorial manner, which quadratic monomial algebra and its ...

Several novel chiral N-heterocyclic carbene and phosphine ligands were prepared from (S)-BINOL. Moreover, their ligated Au complexes were also successfully synthesized and characterized by X-ray crystal diffraction. A weak gold-π interaction between the Au atom and the aromatic ring in these gold complexes was identified. Furthermore, we confirmed the formation of a pair of diastereomeric isome...

We updated our protein-protein docking benchmark to include complexes that became available since our previous release. As before, we only considered high-resolution complex structures that are nonredundant at the family-family pair level, for which the X-ray or NMR unbound structures of the constituent proteins are also available. Benchmark 4.0 adds 52 new complexes to the 124 cases of Benchma...

UNLABELLED microRibonucleic acid (miRNAs) are small regulatory molecules that act by mRNA degradation or via translational repression. Although many miRNAs are ubiquitously expressed, a small subset have differential expression patterns that may give rise to tissue-specific complexes. MOTIVATION This work studies gene targeting patterns amongst miRNAs with differential expression profiles, an...
