(Institute animal reproduction food research, 2017)Vaginocervical stimulation (VCS) induces twice-daily prolactin (PRL) surges resulting in pseudopregnancy in the rat. Furthermore, activation of the extracellular signal-regulated kinase-1/2 (Erk-1/2) is involved in the ...
-
(PLoS ONE, 2013)The Sonic Hedgehog (Shh) pathway is responsible for critical patterning events early in development and for regulating the delicate balance between proliferation and differentiation in the developing and adult vertebrate ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-07-15)The lateral line system comprises an array of mechanosensory organs, the neuromasts, distributed over the body surface. Each neuromast consists of a patch of mechanosensory hair cells surrounded by support cells. We show ...
-
(American Institute of Physics, 2015)We use a particle-in-cell simulation to study the propagation of localized structures in a magnetized electron-positron plasma with relativistic finite temperature. We use as initial condition for the simulation an envelope ...
-
(American Physical Society, 2018)© 2018 American Physical Society. A new definition of proper time, which may incorporate all of the fundamental interactions as well as the whole Poincaré group, is presented. The new proper time definition reduces to the ...
-
(Elsevier, 1984)A calmodulin-Ca2+-stimulated cyclic nucleotide phosphodiesterase (EC 3.1.4.17) which hydrolyzed both cGMP and cAMP has been purified about 2000-fold from ovaries of the amphibian Xenopus laevis. Gel filtration through ...
-
(1985)This paper presents the properties of a new fibre cement material formed by short ductile copper fibres randomly distributed in portland cement paste and compacted by compression to 35 MPa. The optimum percentage and the ...
-
(2004)The reaction of [NPCl2]n first with 2,2′-dihydroxybiphenyl and K2CO3 or (R)-(+)-2,2′-dihydroxy-1,1′-binaphthyl and Cs2CO 3, and subsequently with HO-C6H4-CO 2Prn and Cs2CO3, gave the phosphazene copolymers {[NP(O2C12H8)] ...
-
(Elsevier, 2013)The structural configurations and magnetic properties of zig-zag nanoribbons and nanowires of Fe8−NCoN, for 0≤N≤8, are calculated within the density functional theory. Both, for the zig-zag nanoribbons and the nanowires, ...

(Verlag der Zeitschrift fur Naturforschung, 2001)Viscidone (0.5%), vanillin, 3′,4′-(methylendioxy)acetophenone, 3-ethoxy-4-methoxybenzaldehyde, cinnamic acid, 3-methoxy-4-hydroxymethyl ester were isolated from propolis of hives from Cuncumen. This is the first report on ...
-
(AMERICAN PHYSICAL SOC, 2006-01)A modified version of the Moller-Plesset approach for obtaining the correlation energy associated with a Hartree-Fock ground state is proposed. The method is tested in a model of interacting fermions that allows for an ...
-
(Wiley, 2017)The prediction of reactivity is one of the long-standing objectives of chemistry, contributing to enforce the link between theory and experiment. In particular, the regioselectivity of aromatic molecules has motivated the ...
-
(1993)At temperatures between 25 and 35°C, 100% of Prosopis chilensis seeds germinated within 24 h. At higher temperatures, the germination rate was reduced; at 50°C, seeds did not germinate. After germination at 25°C, the optimal ...
-
(Wiley, 2020)In pursuit of socioeconomic development, many countries are expanding oil and mineral extraction into tropical forests. These activities seed access to remote, biologically rich areas, thereby endangering global biodiversity. ...
-
(Georg Thieme, 1996-11-23)The cytoprotective and anti-inflammatory effects of boldine in an experimental model of acute colitis are reported. The administration of boldine to animals with colitis induced by the intrarectal administration of ...
-
(AMER CHEMICAL SOC, 2010-07-04)Ellipsometry was used to investigate the influence of ionic strength (I) and pH on the adsorption of bovine serum albumin (BSA) or β-lactoglobulin (BLG) onto preabsorbed layers of two polycations: poly(diallyldimethylam ...
-
(2005)Ectokinases can phosphorylate extracellular proteins and external domains of membrane proteins influencing cell adhesion, movement, and cellular interactions. An ectokinase with the properties of casein kinase 2 (CK2) has ...
-
(American Medical Association, 2008-02)Akey molecular pathway implicated in diverse neurodegenerative diseases is the misfolding, aggregation, and accumulation of proteins in the brain. Compelling evidence strongly supports the hypothesis that accumulation ...
-
(1998)Proteinase inhibitors (chymotrypsin and trypsin inhibitors) accumulation in barley leaves was studied when the plants were infested with the aphids Schizaphis graminum and Rhopalosiphum padi. Aphid infestation resulted ...
