L-glucose absorption in house sparrows (Passer domesticus) is nonmediated
(Springer Heidelberg, 2003-12-16)
We previously demonstrated in intact house sparrows substantial absorption in vivo of L-glucose, the stereoisomer of D-glucose that is assumed not to interact with the intestine’s D-glucose transporter. Results of some ...
Characterization of absorptance homogeneity in thin-film coatings for high-power lasers by thermal lensing microscopy
(Optical Society of America, 2019-09)
A focus error method photothermal microscope was designed for the characterization of absorptance homogeneity in thin-film coatings for high-power lasers. The technique relies on the detection of the thermal lens induced ...
Paracellular absorption: A bat breaks the mammal paradigm
(Public Library of Science, 2008-01)
Bats tend to have less intestinal tissue than comparably sized nonflying mammals. The corresponding reduction in intestinal volume and hence mass of digesta carried is advantageous because the costs of flight increase with ...
Unravelling the hydrogen absorption process in Pd overlayers on a Au(111) surface
(Royal Society of Chemistry, 2016-01)
The hydrogen absorption into overlayers of Pd deposited on Au(111) has been investigated by density functional theory (DFT). Hydrogen concentrations, absorption environments, and geometrical and electronic effects have ...
Relation between light absorption measured by the quantitative filter technique and attenuation of Chlorella fusca cultures of different cell densities: application to estimate the absolute electron transport rate (ETR)
(Springer, 2016-06)
In order to estimate microalgal carbon assimilation or production of Chlorella fusca cultures based on electron transport rate (ETR) as in vivo chlorophyll a fluorescence, it is necessary to determine the photosynthetic ...
Fully atomistic real-time simulations of transient absorption spectroscopy
(American Chemical Society, 2018-08)
We have implemented an electron-nuclear real-time propagation scheme for the calculation of transient absorption spectra. When this technique is applied to the study of ultrafast dynamics of Soret-excited zinc(II) ...
Electrothermal metallic furnace atomic absorption spectrometry
(Royal Society of Chemistry, 2017-02)
We present an atomization system for atomic absorption spectrometry comprised of a stainless steel furnace heated by the Joule effect by means of its intrinsic resistance. This new kind of furnace does not require any gases ...
Absorption Kinetics of Sulfur Dioxide in Flint Corn during Steeping
(Elsevier Science, 2001-08)
A mathematical model was proposed to simulate simultaneous sulfur dioxide absorption and reaction during corn steeping. The parameters of the model, the diffusion coefficient and the reaction rate constant, were determined. ...
Lithocholic acid: A new emergent protector of intestinal calcium absorption under oxidant conditions
(National Research Council Canada-NRC Research Press, 2017-04)
LCA and 1,25(OH)2D3 are vitamin D receptor ligands with different binding affinity. The secosteroid stimulates intestinal Ca2+ absorption. Whether LCA alters this process remains unknown. The aim of our work was to determine ...
Naringin prevents the inhibition of intestinal Ca2+ absorption induced by a fructose rich diet
(Elsevier Science Inc, 2017-12)
This study tries to elucidate the mechanisms by which fructose rich diets (FRD) inhibit the rat intestinal Ca2+ absorption, and determine if any or all underlying alterations are prevented by naringin (NAR). Male rats were ...
