β-Glucans: Relationships between Modification, Conformation and Functional Activities

Molecules, 2017
β-glucan is a type of polysaccharide which widely exists in bacteria, fungi, algae, and plants, and has been well known for its biological activities such as enhancing immunity, antitumor, antibacterial, antiviral, and wound healing activities.

Conformal Covariantes

Publications of the Research Institute for Mathematical Sciences, 1986
(From the author's introduction) ''By a conformal covariant we mean a holomorphic differential operator which intertwines two holomorphic representations of the conformal group SU(2,2). In this article we determine all such. [...] The determination of the set of covariant differential operators is equivalent to the determination of the set of ...

Conformal Automorphisms and Conformally Flat Manifolds [PDF]

Transactions of the American Mathematical Society, 1991
A geometric structure on a smooth n n -manifold M M is a maximal collection of distinguished charts modeled on a 1 1 -connected n n -dimensional homogeneous space X X of a Lie group G G where coordinate changes are restrictions of transformations ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Molecular dynamics of 18-crown-6 complexes with alkali-metal cations and urea: Prediction of their conformations and comparison with data from the cambridge structural database [PDF]

, 1993
Complexes of 18-crown-6 with alkali-metal cations (Na+, K+, and Rb+), urea, and the uncomplexed crown ether were studied in vacuo with the molecular dynamics method. Conformational data from these calculations (simulation times in the range from 6-15 ns)

6d Conformal matter [PDF]

Journal of High Energy Physics, 2015
A single M5-brane probing G, an ADE-type singularity, leads to a system which has G x G global symmetry and can be viewed as "bifundamental" (G,G) matter. For the A_N series, this leads to the usual notion of bifundamental matter. For the other cases it corresponds to a strongly interacting (1,0) superconformal system in six dimensions.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Carcass characteristics of feedlot-finished Nellore heifers slaughtered at different weights

Acta Scientiarum: Animal Sciences, 2019
Carcass and meat characteristics of 48 Nellore heifers at 24 to 30 months of age, with an initial weight of 263.4 ± 13.9 kg, were evaluated. The experiment was set up as a completely randomized design with four treatments, which consisted of four ...

Conformation-networks of two-dimensional lattice homopolymers

, 2005
The effect of different Monte Carlo move sets on the the folding kinetics of lattice polymer chains is studied from the geometry of the conformation-network. The networks have the characteristics of small- world. The Monte Carlo move, rigid rotation, has
