Determination of a Robust Assay for Human Sperm Membrane Potential Analysis
(Frontiers Media, 2019-06)
Mammalian sperm must undergo a complex process called capacitation in order to fertilize the egg. During this process, hyperpolarization of the sperm plasma membrane has been mostly studied in mouse, and associated to its ...
The amniotic membrane in ophthalmology
(Elsevier B.V., 2004-01-01)
The amniotic membrane is the innermost of the three layers forming the fetal membranes. It was first used in 1910 in skin transplantation. Thereafter it has been used in surgical procedures related to the genito-urinary ...
Probing the pore size of the hemocyanin channel
(1982)
We have studied single-channel conductance for different monovalent cations and streaming potentials caused by osmotic gradients of non-electrolytes in hemocyanin-treated membranes. We have found that the smaller ion, which ...
Labaditin, a cyclic peptide with rich biotechnological potential: preliminary toxicological studies and structural changes in water and lipid membrane environment
(Springer, 2011-01-01)
Cyclic peptides isolated from the plants of the Euphorbiaceae family have been largely studied due to their rigid conformation, which is considered significant for biologic activity. The peptide Labaditin (L(0)) and its ...
Spectrophotometric flow-injection determination of sulphite in white wines involving gas diffusion through a concentric tubular membrane
(2003-07-14)
A flow-injection system is proposed for the spectrophotometric determination of sulphite in white wines. The method involves analyte conversion to SO2, gas diffusion through a Teflon® semi-permeable membrane, collection ...

Role of guanidinium group in the insertion of l-arginine in DMPE and DMPC lipid interphases
(Elsevier Science, 2010-03)
l-Arginine (Arg) is a positively charged amino acid constituent of peptides and proteins, participating in diverse mechanisms of protein-membrane interaction. The effect of Arg on phosphatidylcholine (PC) membranes has ...
