Incorporation of dihydroretinals into the sensory rhodopsin SR and bacteriorhodopsin bR has led to a modified version of the external point-charge model for bR proposed in 1979. Difference Fourier transform infrared studies of native bR and bR analogs cultured on media containing isotopes of amino acids have shown some of the amino acids which undergo environmental changes or deprotonation/prot...

The title compound, C(8)H(12)NO(+)·Br(-), is built up from roughly planar (r.m.s. deviation for the non-H atoms = 0.062 Å) protonated 4-eth-oxy-anilimium cations and Br(-) anions. In the crystal, the cations and anions are linked by N-H⋯Br and N-H⋯(Br,Br) hydrogen bonds, generating (100) sheets. Very weak C-H⋯π inter-actions may also help to stabilize the crystal structure.

Brassinosteroid (BR) homeostasis and signaling are crucial for normal growth and development of plants. BR signaling through cell-surface receptor kinases and intracellular components leads to dephosphorylation and accumulation of the nuclear protein BZR1. How BR signaling regulates gene expression, however, remains unknown. Here we show that BZR1 is a transcriptional repressor that has a previ...

Let k be a field finitely generated over the field of rational numbers, and Br (k) the Brauer group of k. For an algebraic variety X over k we consider the cohomological Brauer–Grothendieck group Br (X). We prove that the quotient of Br (X) by the image of Br (k) is finite if X is a K3 surface. When X is an abelian variety over k, and X is the variety over an algebraic closure k of k obtained f...

In the title compound, [PdBr(2)(C(21)H(21)As)(2)], the Pd(II) ion, residing on a centre of symmetry, is coordinated by two As donor atoms [Pd-As = 2.4276 (2) Å] and two Br anions [Pd-Br = 2.4194 (2) Å] in a distorted square-planar geometry [Br-Pd-As = 87.786 (7)°]. A weak intra-molecular C-H⋯Br inter-action occurs. In the crystal structure, inter-molecular C-H⋯Br inter-actions are observed.

The title compound, C(7)H(10)NO(+)·Br(-), consists of almost planar 4-methoxy-anilinium cations, wherein the O atom lies 0.049 (3) Å out of the plane formed by the non-H atoms, and a Br(-) anion. Strong N-H⋯Br and N-H⋯(Br,Br) hydrogen bonding contributes to the stability of the crystal structure and links the cations and anions into a three-dimensional network.

BACKGROUND The aim of the present study was to evaluate potential psychosocial factors that impact Chinese female breast cancer patients to select breast reconstruction (BR), and potential connection of psychosocial outcomes with their satisfaction with BR. METHODS A total of 264 female breast cancer patients with mastectomy were recruited from 2012 to 2014. All patients were informed with BR...
