The phase transition temperatures of several lipidic systems were determined using two different techniques: dynamic light scattering (DLS) and steady-state fluorescence anisotropy, using two fluorescent probes that report different membrane regions (TMA-DPH and DPH). Atomic force microscopy (AFM) was used as a complementary technique to characterize(More)
Probing drug/lipid interactions at the molecular level represents an important challenge in pharmaceutical research, drug discovery and membrane biophysics. Previous studies showed that enrofloxacin metalloantibiotic has potential as an antimicrobial agent candidate, since it exhibits antimicrobial effect comparable to that of free enrofloxacin but a(More)
Machado Joseph Disease (MJD) is the most frequent autosomal dominantly inherited cerebellar ataxia caused by the over-repetition of a CAG trinucleotide in the ATXN3 gene. This expansion translates into a polyglutamine tract within the ataxin-3 protein that confers a toxic gain-of-function to the mutant protein ataxin-3, contributing to protein misfolding(More)
A major requirement to perform structural studies with membrane proteins is to define efficient reconstitution protocols that ensure a high incorporation degree and protein directionality and topology that mimics its in vivo conditions. For this kind of studies, protein reconstitution in membrane systems via a detergent-mediated pathway is usually(More)
Spiny-footed lizards constitute a diverse but scarcely studied genus. Microsatellite markers would help increasing the knowledge about species boundaries, patterns of genetic diversity and structure, and gene flow dynamics. We developed a set of 22 polymorphic microsatellite loci for cross-species amplification in three taxa belonging to the Acanthodactylus(More)
Live-trapping elusive animals is often challenging, hampering the achievement of reasonable sample sizes for molecular studies. In such cases, the use of noninvasive samples (NIS) is critical in many research fields, mostly related to ecology, management and conservation of wild species. We analysed the influence of several variables potentially associated(More)
