(11)B MAS NMR and First-Principles Study of the [OBO3] Pyramids in Borates.

Borates are built from the [Bϕ3] planar triangles and the [Bϕ4] tetrahedral groups, where ϕ denotes O or OH. However, the [Bϕ4] groups in some borates are highly distorted to include three normal B-O bonds and one anomalously long B-O bond and, therefore, are best described as the [OBO3] pyramids. Four synthetic borates of the boracite-type structures (Mg3B7O13Br, Cu3B7O13Br, Zn3B7O13Cl, and Mg3B7O13Cl) containing a range of [OBO3] pyramids were investigated by multifield (7.

Polymorphism of NaVO2F2: a P2₁/c superstructure with pseudosymmetry of P2₁/m in the subcell.

The ADDSYM routine in the program PLATON [Spek (2015). Acta Cryst. C71, 9-18] has helped researchers to avoid structures of (metal-)organic compounds being reported in an unnecessarily low symmetry space group.

Homeopathy for infertility treatment: a case series.

Homeopathy has been used in the past for treating a broad aspect of diseases. In gynecology, its use remains limited. Taking under consideration its clinical aspects, the authors attempted to use it for treating female sub fertility problems.

Growth of some mycobacterial strains in 7H12 Middlebrook liquid medium in the presence of auramine.

The action of auramine on the growth of some mycobacterial strains in 7H12 Middlebrook liquid medium as well as the interaction between auramine and calf thymus DNA were investigated. It was concluded that the inhibitory effect of auramine on the growth of some mycobacterial strains belonging to the TB complex or MOTT bacilli is the result of a double mechanism: interaction of auramine with mycolic acid and interaction between the dye and the mycobacterial DNA.

Growth of M. tuberculosis H37Rv strain in 7H12 Middlebrook liquid medium in the presence of acridine orange and THA.

The influence of acridine orange and THA on the growth of Mycobacterium tuberculosis H37Rv strain in 7H12 Middlebrook liquid medium was studied. As compared to acridine orange, THA also inhibited the growth of the H37Rv Mycobacterium tuberculosis strain but at much higher concentrations.

L cell virus: infectivity for type N and B mouse embryo cells.

The efficiency of focus formation of four L cell virus populations was significantly higher on type N mouse embryo fibroblast cultures than on type B cells. [5-3H]uridine-incorporating material sedimenting at a density of 1.158/g/cm3 was observed in the supernatant fluids of type N and B cultures infected with the four viral populations.
