Leukocyte adhesion to the vasculature is mediated by E-, P-, and L-selectins. The natural ligands for E- P-selectins have not been fully characterized but shown contain tetrasaccharide sialyl Lewis x structure (SLe(x)). To determine importance of fucose moiety SLe(x), various analogs SLe(x) containing modifications thereof were prepared tested as inhibitors E-selectin-mediated cell adhesion. Cellular experiments indicate that replacement hydroxyl groups hydrogen abrogated E-selectin binding....
1. Diets high in total lipids, saturated fatty acids, trans and having ω-6:ω-3 acid ratios, have been shown to be related increased instances of coronary heart disease, while diets ω-3 acids decrease the risk. 2. Feeding laying hens has improve quality eggs produced terms saturation content. 3. A study was undertaken determine if source, when fed hens, influences amount transferred eggs. 4. Flaxseed flaxseed oil, along with chia seed were two main sources examined during 84 d trial. 5. All...
Para confirmar la presencia de avispa polinizadora Ficus religiosa en República Dominicana, se recolectaron cinco siconos cuatro árboles ubicados igual número localidades ciudad Santo Domingo. En todos encontró Platyscapa quadraticeps Mayr, 1885. Este hallazgo constituye el primer registro una especie introducida familia Agaonidae para Dominicana y incrementa a tres géneros especies diversidad conocida esta Hispaniola.
An edible film to carry l-(+)-ascorbic acid (AA) was formulated for natural antioxidant food protection. Considering previous works where films based on the "rigid" structure of gellan (deacylated) or a mixture acylated−deacylated (more "disordered") were used network development, pectin herein chosen by considering that alternating presence "disordered" (hairy) regions together with ordered (homogalacturonan) ones could sufficiently immobilize water better AA retention and lower browning....
The basis set and the functional dependence of one-bond carbon-carbon NMR spin-spin coupling constants (SSCC) have been analyzed using density theory. Four sets (6-311G**, TZVP, EPR-III, aug-cc-pVTZ-J) four functionals (PBE, PW91, B3LYP, B3P86) are tested by comparison with 70 experimental values corresponding to 49 molecules that represent multiple types hybridization carbon atoms. two hybrid B3P86 B3LYP combined either EPR-III or aug-cc-pVTZ-J lead best accuracy calculated SSCC. However, a...
Optimized shifting and/or scaling factors for calculating one‐bond carbon–hydrogen spin–spin coupling constants have been determined 35 combinations of representative functionals (PBE, B3LYP, B3P86, B97‐2 and M06‐L) basis sets (TZVP, HIII‐su3, EPR‐III, aug‐cc‐pVTZ‐J, ccJ‐pVDZ, ccJ‐pVTZ, ccJ‐pVQZ, pcJ‐2 pcJ‐3) using 68 organic molecular systems with 88 1 J CH couplings including different types hybridized carbon atoms. Density functional theory assessment the determination is examined,...
Abstract The fatty acid composition and total lipids of various forage crops at different cutting dates seasons, which are used in grazing beef production Argentina, were determined. Three experiments carried out the Agricultural Experimental Station INTA , Anguil, La Pampa, Argentina Samples alfalfa from three cultivars with dormancy groups (G4‐5, G6‐7 G8‐9) samples ryegrasses Bill, Florida Queue, wheats Charrua Guapo, triticale Don Santiago taken analysed for composition. Significant...
The hydrolytic and oxidative stability of L-(+)-ascorbic acid (AA) into plasticized pectin films were separately studied in view preserving vitamin C activity and/or to achieve localized antioxidant at pharmaceutical food interfaces. Films made with each one the enzymatically tailored pectins (50%, 70%, 80% DM; Cameron et al. Carbohydr. Polym.2008, 71, 287-299) or commercial high methoxyl (HMP; 72% DM). Since AA was dependent on water availability network, nanostructure affected kinetics....
Abstract A 120-d feeding trial was conducted to determine the effect of alfalfa (Medicago sativa) on growth and chemical composition, fatty acid content, nutritional lipid indices meat grass carp (Ctenopharyngodon idella). Two experimental diets were used: pellet (AP) diet artificial grain (GD). Final weight, feed conversion rate, protein efficiency ratio significantly greater in GD group (P < 0.05). However, no differences length condition factor observed. The composition differed...
Abstract The potential of NMR spin–spin coupling constants as probes to study fine details electronic molecular structures is briefly discussed in this work through two different examples. A qualitative analysis the polarization propagator expression for Fermi contact term applied predicting factors affecting 1 J CH , and comments are made about how generalize those results types one‐bond spin‐spin couplings. Moreover, Natural Coupling method get insight into defining a Karplus relationship...
Vicinal (3)JHH coupling constants for monosubstituted ethane molecules present the unusual relationship (180°) < (0°) when substituent contains bonding and antibonding orbitals with strong hyperconjugative interactions involving bond antibond of fragment. This anomalous behavior is studied as a function rotation three model systems (propanal, thiopropanal, 1-butene) at B3LYP/TZVP level. The consistency this level theory to study problem previously established using different ab initio...
