Quercetin diminishes the binding of hemoglobin to the red blood cell membrane
(Mary Ann Liebert IncNew RochelleEUA, 2001)
Crystal structure of a dimeric Ser49 PLA(2)-like myotoxic component of the Vipera ammodytes meridionalis venomics reveals determinants of myotoxicity and membrane damaging activity
(Royal Soc Chemistry, 2012-01-01)
Myotoxicity and membrane damage play a central role in the life-threatening effects of the viper envenomation. Myotoxins are an important part of the viper venomics. A Ser49 PLA(2)-like myotoxin from the venom of Vipera ...
Damage and repair of the neuronal membrane: From neural development to axonal trauma and restoration
Integrity of the plasma membrane is essential for the maintenance of physiological conditions, metabolic activity and the shape of eukaryotic cells. In neurons, the plasma membrane surrounding the axon—the axolemma—fulfills ...
Slow imbibition of Annona emarginata (Annonaceae) seeds: Metabolic and ultrastructural evaluations
Germination pattern may be affected when seeds are dispersed under flooded conditions or subjected to pre-germination treatments such as immersion in plant growth regulators and priming. We evaluated the metabolic and ...
Bovine sperm cells viability during incubation with or without exogenous DNA
(CAMBRIDGE UNIV PRESS, 2009)
The aim of this study was to assess the effect of exogenous DNA and incubation time on the viability of bovine sperm. Sperm were incubated at a concentration of 5 x 10(6)/ml with or without plasmid pEYFP-NUC. Fluorescent ...
Insights on calcium-independent phospholipid membrane damage by Lys49-PLA(2) using tryptophan scanning mutagenesis of bothropstoxin-I from Bothrops jararacussu
(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2008)
Bothropstoxin-I (BthTx-I) is a homodimerie Lys49-PLA(2) from the venom of the snake Bothrops jararacussu, which lacks hydrolytic activity against phospholipid substrates, yet permeabilizes membranes by a Ca2+- independent ...
