(Wiley, 2018-04)Ecosystems where carbon fluxes are being monitored on a global scale are strongly biased toward temperate Northern Hemisphere latitudes. However, forest and moorland ecosystems in the Southern Hemisphere may contribute ...
-
(American Chemical Society, 2006-03-16)In this work surface-enhanced resonance Raman spectroscopic experiments have demonstrated that metallic single-walled carbon nanotubes can be used as chemical assemblies between the pyrene analyte and the silver colloidal ...
-
(Royal Society of Chemistry, 2017)© 2017 The Royal Society of Chemistry. In this work, the electrochemical reduction of carbon dioxide using [Mn+(cyclam)Cln] (M = Ni2+ and Co3+) as electrocatalysts has been studied in 1-butyl-3-methylimidazolium tetrafluoroborate ...
-
(Hindawi, 2014)Measurements of carbonaceous aerosols in South American cities are limited, and most existing data are of short term and limited to only a few locations. For 6 years (2002–2007), concentrations of fine particulate matter ...
-
(John Wiley & Sons, Ltd., 1997-10-09)Tbe cardiovascular etTeets of (±)-norannepavine, a benzylisoquinoline alkaloid of natural origin, have been detennined on anaesthetized rats in vivo, on spontaneously beating atria and on aortic smooth muscle. In aorta, ...
-
(MDPI, 2021)Light is an important cue that stimulates both plastid development and biosynthesis of carotenoids in plants. During photomorphogenesis or de-etiolation, photoreceptors are activated and molecular factors for carotenoid ...
-
(Springer New York, 2016)© Springer International Publishing Switzerland 2016. Carrot (Daucus carota) is one of the most important vegetable cultivated worldwide and the main source of dietary provitamin A. Contrary to other plants, almost all ...
-
(Springer Verlag, 2015)© 2015, Springer-Verlag Berlin Heidelberg. The primary carotenoid synthesized by Xanthophyllomycesdendrorhous is astaxanthin, which is used as a feed additive in aquaculture. Cell growth kinetics and carotenoid production ...

(Springer, 2015)The primary carotenoid synthesized by Xanthophyllomyces dendrorhous is astaxanthin, which is used as a feed additive in aquaculture. Cell growth kinetics and carotenoid production were correlated with the mRNA levels of ...
-
(Wiley-Blackwell, 2015)In Schizosaccharomycespombe, ribosomal protein gene (RPG) promoters contain a TATA analogue element called the HomolD box. The HomolD-binding protein Rrn7 forms a complex with the RNA polymeraseII machinery. Despite the ...
-
Casimir force induced by electromagnetic wave polarization in Kerr, Gödel and Bianchi–i spacetimes (Springer, 2020)Electromagnetic waves propagation on either rotating or anisotropic spacetime backgrounds (such as Kerr and Godel metrics, or Bianchi-I metric) produce a reduction of the magnitude of Casimir forces between plates. These ...
-
(1997)We studied the effects of sodium nitroprusside, a nitric oxide donor, on the chemosensory responses to cyanide and nicotine in the cat carotid body. In situ, sodium nitroprusside infusion reduced the cyanide-evoked responses ...
-
(1981)The general acid catalysed hydrolysis and the intramolecular nucleophilic anionic cyclization of acyloximes operate concurrently in water at pH 7-9. Hydrolysis is inhibited by cationic micelles; changing the length of the ...
-
(MDPI, 2021)Amyloids are supramolecular assemblies composed of polypeptides stabilized by an intermolecular beta-sheet core. These misfolded conformations have been traditionally associated with pathological conditions such as Alzheimer's ...
-
(Elsevier, 2012)In some archaea, glucose degradation proceeds through a modified version of the Embden-Meyerhof pathway where glucose and fructose-6-P phosphorylation is carried out by kinases that use ADP as the phosphoryl donor. Unlike ...
-
(Springer, 2013)Pyridoxal 50-phosphate is the active form of vitamin B6 and its deficiency is directly related with several human disorders, which make human pyridoxal kinase (hPLK) an important pharmacologic target. In spite of this, ...
-
(Elsevier, 2003)The petrosal ganglion (PG) is entirely constituted by the perikarya of primary sensory neurons, part of which innervates the carotid body via the carotid sinus nerve (CSN). Application of acetylcholine (ACh) or nicotine ...
-
(1997)1. Conductance of heterotrimeric rat epithelial Na+ channels (α,β,γ-rENaCs) for Li+ and Na+ in planar lipid bilayers was a non-linear function of ion concentration, with a maximum of 30.4 ± 2.9 pS and 18.5 ± 1.9 pS at 1 M ...

(2011)In this paper, we study differential equations with piecewise constant argument of generalized (DEPCAGs) type, i.e., the argument is a general step function. They are hybrid equations combining properties of continuous and ...
