(2007)2,5-Dimethoxy-4-substituted phenylisopropylamines and phenethylamines are 5-hydroxytryptamine (serotonin) (5-HT)(2A/2C) agonists. The former are partial to full agonists, whereas the latter are partial to weak agonists. ...
-
(2007)The electrophilicity index, omega, of a series of substituted ethylenes used in some relevant organic reactions has been evaluated from the ionization potential JP) and the electron affinity (EA) computed by vertical ...
-
(2007)The petrosal ganglion (PG) contains the somata of primary afferent neurons that innervate the chemoreceptor (glomus) cells in the carotid body (CB). The most accepted model of CB chemoreception states that natural stimuli ...
-
(2007)The alkaloid profile of the aerial parts of Schizanthus tricolor Grau et Gronbach was investigated by GC-MS. Seventeen alkaloids were detected and are reported in this species for the first time. They were identified by ...
-
(2007)First-principles calculations of the equation of state and single-crystal elastic constants of platinum have been carried out to 650 GPa using density-functional theory (DFT). The present equation of state deduced at 300 ...
-
(2007)We describe the operation of a midbrain neural circuit in pigeons that may participate in selecting and attending to one visual stimulus from the myriad displayed in their visual environment. This mechanism is based on a ...
-
(2007)We study the properties of junctions created by the crossing of N identical branches of linear discrete networks. We reveal that for N > 2 such a junction creates a topological defect and supports two types of spatially ...
-
(2007)We report a theoretical study on a series of CDK2 inhibitors using a set of global reactivity indices defined in terms of the density of states. The statistical analysis was performed on the basis of two groups of 11 and ...
-
(2007)In this work the partial molar volumes (V) of different anionic polyelectrolytes and hydrophobically modified polyelectrolytes (PHM) were measured. Polymers like polymaleic acid-co-styrene, polymaleic acid-co-1-olefin, ...
-
(2007)Bud-break and the length and depth of endodormancy (ED) were studied in grapevine (Vitis Vinifera L.) cv. Thompson Seedless (Sultana) grown in the Elqui (warm winter) and in the Maipo (temperate winter) valleys of north ...
-
(2007)Template-directed synthesis is a promising route to realize vanadate-based 1-D nanostructures, an example of which is the formation of vanadium pentoxide nanotubes and associated nanostructures. In this work, we report the ...
-
(2007)Anisotropic specimens of MoS2 are obtained by pressing the microcrystalline powder into special die. This inelastic compression results in a rearrangement of the disulfide micro platelets observed by atomic force microscopy ...
-
(2007)What are the consequences of the natural variation in maternal body mass on offspring energetic performance? How are performance traits related to thermal physiology and energetics phenotypically integrated on offspring? ...
-
(2007)A new method for the simultaneous determination of copper and gold was developed by derivative spectrophotometry using a previous preconcentration on solid phase. The method is based on the formation of Cu(II)-PPDOT and ...
-
(2007)We demonstrate that all-trans retinoic acid (RA) induces Ill adaptive T regulatory cells (A-Tregs) to acquire a gut-homing phenotype (alpha 4 beta 7(+) CC chemokine receptor 9(+)) and the capacity to home to the lamina ...
-
(2007)The effect of mutualists (i.e. pollinators) and antagonists (i.e. herbivores) can have non-additive effects on plant fitness. This is often interpreted as evidence for correlated evolution on a suite of traits leading to ...
-
(2007)Female fecundity increases with body size in a variety of insects, but it is unknown if this generalization applies for kissing bugs. In this study, we evaluate whether gonad weight in, the bloodsucking insect Mepraia ...
-
(2007)We compared the relative importance of chemical alellopathy, pruning behaviour of resident ants and other non-related agents to ant-plant mutualism for seedling establishment beneath TriplaTiS americana L. (Polygonaceae), ...
-
(2007)Some zigzag and all armchair single-walled carbon nanotubes are believed to behave as metals. However, recent experimental results suggest that only armchair single-walled carbon nanotubes show typically metallic behavior. ...
-
(2007)This work reports the successful realization of MoS2 nanotubes by a novel intercalation chemistry and hydrothermal treatment. An inorganic-organic precursor of hexadecylamine (HDA) and molybdenum disulphide (MoS2) were ...
