Orthomyxovirus Influenza A virus (IAV) heterotrimeric polymerase performs transcription of viral mRNAs by cap-snatching, which involves generation of capped primers by host pre-mRNA binding via the PB2 subunit cap-binding site and cleavage 10-13 nucleotides from the 5' cap by the PA subunit endonuclease. Thogotoviruses, tick-borne orthomyxoviruses that includes Thogoto (THOV), Dhori (DHOV) and ...

A series of molybdate, MoO4(2-), salts have been studied using solid-state 95Mo NMR spectroscopy at applied magnetic field strengths of 11.75, 17.63 and 21.14 T. In contrast to previous investigations, the principal components of the Mo shielding and EFG tensors have been obtained, as well as their relative orientations. At the fields employed, the anisotropic Mo shielding and quadrupolar inter...

We present experimental and theoretical studies of the optical response of mixed Ag(n)Au(+)(4-n) (n=1-3) clusters in the photon energy range ℏω = 1.9-3.5 eV. Absorption spectra are recorded by a newly built longitudinal molecular beam depletion spectroscopy apparatus providing lower limits to absolute photodissociation cross sections. The experimental data are compared to optical response calcu...

In the present investigation, a systematic study on the dependence of chelating agents on the size control of silver phosphate Ag3PO4 powders is presented. The effect of two different capping-ligands (monoethanolamine (MEA) and oleylamine (OLA) as amino-additives) is studied using sol-gel route. Structural and morphological characterization techniques were used to quantify...

the ability of natural clinoptilolite and its modified forms were studied for removal of pahs from n-paraffin. surfactant modified zeolite (smz) was obtained by modifying clinoptilolite with hexadecyltrimethylammonium ion. homoionic forms of zeolite were obtained by ion exchange process using inorganic salts of desirable cations (e.g. ag+, fe3+…). natural clinoptilolite and its cation exchanged...

The title compound, sodium disilver arsenatotrimolybdate, Na(0.93 (1))Ag(2.07 (1))Mo(3)AsO(13), was prepared by a solid-state reaction. In the crystal structure, isolated AsO(4) tetra-hedra share corners with groups of three edge-sharing MoO(6) octa-hedra. This arrangement leads to the formation of anionic (1) (∞)[Mo(3)AsO(13)](n) ribbons extending parallel to [100]. The three metal sites show ...

Effects of duration of exposure of single metal cations (Ag+1, Cd+2, Cu+2, Ga+3, Ni+2, and Zn+2) on 3H-thymidine (3H-Tdr) incorporation and 3-[4,5-dimethyl-thiazol-2yl-]-2,5-diphenyl tetrazolium bromide-formazan (MTT-f) production in cultured murine fibroblasts (Balb/c 3T3) were investigated, and the synergistic and antagonistic effects of two metal cations applied simultaneously to the fibrobl...

In the title coordination polymer, [Ag(2)(NCS)(2)(C(27)H(26)P(2))(2)](n), two centrosymmetrically related Ag(+) cations are linked by two thio-cyanate anions into binuclear eight-membered macrocycles. The Ag⋯Ag separation within the macrocycle is 5.4400 (6) Å. The distorted tetra-hedral coordination about each metal atom is completed by the P atoms of two bridging 1,3-bis-(diphenyl-phosphan-yl)...
