L-Proline uptake in Crithidia deanei is influenced by its endosymbiont bacterium
(WILEY-BLACKWELL, 2008)
Crithidia deanei, a monoxenic trypanosomatid, presents an endosymbiotic bacterium in its cytoplasm. Both the protozoan and the bacterium maintain intensive metabolic exchange, resulting in an interesting model to study the ...
Replacement of a proline with silaproline causes a 20-fold increase in the cellular uptake of a pro-rich peptide
(AMER CHEMICAL SOC, 2006-07-05)
The results presented here show that elementary design enhancements have led to a 20-fold increase in the cellular uptake properties of a Pro-rich cell-penetrating peptide. These results are relevant not only due to the ...
Zn uptake, physiological response and stress attenuation in mycorrhizal jack bean growing in soil with increasing Zn concentrations
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
The influence of arbuscular mycorrhizal fungi (AMF) inoculation on Canavalia ensiformis growth. nutrient and Zn uptake, and on some physiological parameters in response to increasing soil Zn concentrations was studied. ...
24-epibrassinolide restores nitrogen metabolism of pigeon pea under saline stress
(SpringerNew YorkEUA, 2013)
Effect of amino acids and peptides on growth of pediococcus pentosaceus from wine
(Plapiqui, 2003-09)
Lactic acid bacteria are characterized by numerous nutritional requirements. The influence of amino acids and peptides on the growth of Pediococcus pentosaceus c1 isolated from argentinean wines was determined. Cells were ...
Arbuscular mycorrhiza alters metal uptake and the physiological response of Coffea arabica seedlings to increasing Zn and Cu concentrations in soil
(Elsevier Science BvAmsterdamHolanda, 2010)
Intestinal perfusion indicates high reliance on paracellular nutrient absorption in an insectivorous bat Tadarida brasiliensis
(Elsevier, 2013-03)
Flying vertebrates have been hypothesized to have a high capacity for paracellular absorption of nutrients. This could be due to high permeability of the intestines to nutrient-sized molecules. We performed intestinal ...
The GATA-type transcriptional activator Gat1 regulates nitrogen uptake and metabolism in the human pathogen Cryptococcus neoformans
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011)
Nitrogen uptake and metabolism are essential to microbial growth. Gat1 belongs to a conserved family of zinc finger containing transcriptional regulators known as GATA-factors. These factors activate the transcription of ...
Species-specific effects of the invasive Hieracium pilosella in Magellanic steppe grasslands are driven by nitrogen cycle changes
(Springer, 2015-12)
Aims: The principal objective was to evaluate the interference by the invasive species, H. pilosella, on native grassland species at the physiological performance level. We hypothesised that the invasive species is able ...
Glucose uptake in the mammalian stages of Trypanosoma cruzi
(ELSEVIER SCIENCE BV, 2009)
Trypanosoma cruzi, the agent of Chagas` disease, alternates between different morphogenetic stages that face distinct physiological conditions in their invertebrate and vertebrate hosts, likely in the availability of ...
