The baroreflex (BR) reflects autonomic blood pressure control. Alzheimer's disease (AD) affects the autonomic system. Detailed properties of BR in AD are unknown. We hypothesized that BR is reduced in AD, and is influenced by autonomic effects of cholinesterase inhibitors (ChEI). BR was determined in 18 AD patients, 11 patients with mild cognitive impairment (MCI) and 19 healthy control subject...

In the crystal structure of the title compound, C(5)H(5)BrN(2), mol-ecules assemble via pairs of N-H⋯N hydrogen bonds into inversion dimers using only the syn H atom on the amine group. These dimers then assemble further into two-dimensional layers via type I C-Br⋯Br [Br⋯Br = 3.693 (s6) Å] halogen bonding along the (102) plane.

The unique energy transfer interaction between the optical protein bacteriorhodopsin (bR) and CdSe/ZnS quantum dots (QDs) provides a potential modulation mechanism for bio-nano electronic application. We have utilized ionic-self assembled monolayer (I-SAM) techniques to create a novel alternating monolayer system of QDs and bR on a conductive ITO substrate. Results demonstrate the ability to ef...

The transcription factor Broad Complex (BR-C) is an early ecdysone response gene in insects and contains two types of domains: two zinc finger domains for the activation of gene transcription and a Bric-a-brac/Tramtrack/Broad complex (BTB) domain for protein-protein interaction. Although the mechanism of zinc finger-mediated gene transcription is well studied, the partners interacting with the ...

Brassinosteroids (BRs) are a group of steroidal hormones involved in plant development. Although the BR biosynthesis pathways are well characterized, the BR inactivation process, which contributes to BR homeostasis, is less understood. Here, we show that a member of the BAHD (for benzylalcohol O-acetyltransferase, anthocyanin O-hydroxycinnamoyltransferase, anthranilate N-hydroxycinnamoyl/benzoy...

The 2B5 region on the X chromosome of Drosophila melanogaster forms an early ecdysone puff at the end of the third instar. The region is coextensive with a complex genetic locus, the Broad-Complex (BR-C). The BR-C is a regulatory gene that contains two major functional domains, the br domain and the l(1)2Bc domain. BR-C mutants prevent metamorphosis, including morphogenesis of imaginal discs; b...

Three N-ar-yl-2,2,2-tri-bromo-acetamides, namely, 2,2,2-tri-bromo-N-(2-fluoro-phen-yl)-acetamide, C8H5Br3FNO, (I), 2,2,2-tri-bromo-N-[3-(tri-fluoro-methyl)-phen-yl]-acetamide, C9H5Br3F3NO, (II) and 2,2,2-tri-bromo-N-(4-fluoro-phen-yl)-acetamide, C8H5Br3FNO, (III) were synthesized and their crystal structures were analysed. In the crystal structure of (I), C-Br⋯πar-yl inter-actions connect the m...

Random basketball routing (BR) [1] is a simple protocol that integrates MAC and multihop routing in a crosslayer optimized manner. Due to its lightness and performance, BR would be quite suitable for sensor networks, where communication nodes are usually simple devices. In this paper, we describe how we implemented BR in a ZigBee-based (IEEE 802.15.4) sensor network. In [1], it is verified that...
