Ressonância paramagnética eletrônica de radicais nitróxidos e nanobastões de ouro funcionalizados com marcadores de spin
(Universidade Federal de Minas GeraisUFMG, 2018-07-05)
For this work, a novell spin label specific for gold nanostructures was synthesized (ALTEMPOL). Having a nitroxide radical group, it was synthesized by means of an esterification reaction of TEMPOL (1-Oxyl-2,2,6,6-tetram ...
Effect of polysaccharide capsule of the microalgae Staurastrum iversenii var. americanum on diffusion of charged and uncharged molecules, using EPR technique
(Sociedade Brasileira de Física, 2006-03-01)
The existence of a mucilaginous envelope, sheath or capsule is usual in many desmids, but few data concerning its function are available. Previous studies of the transport function and permeation of molecules through the ...
Simultaneous recording of task-induced changes in blood oxygenation, volume, and flow using diffuse optical imaging and arterial spin-labeling MRI

Structural properties of lipid reconstructs and lipid composition of normotensive and hypertensive rat vascular smooth muscle cell membranes
(Associação Brasileira de Divulgação Científica, 2009-09-01)
Multiple cell membrane alterations have been reported to be the cause of various forms of hypertension. The present study focuses on the lipid portion of the membranes, characterizing the microviscosity of membranes ...

Formation of lipid bilayers on the pore walls of macroporous silicon
(Elsevier Science SA, 2019-02)
Electron paramagnetic resonance (EPR) spectroscopy was used to study the pore filling of macroporous silicon with lipid vesicles (liposomes), added with a spin label. Different EPR spectra were obtained with the magnetic ...
The Use of Mn(II) Bound to His-tags as Genetically Encodable Spin-Label for Nanometric Distance Determination in Proteins
(American Chemical Society, 2016-03)
A genetically encodable paramagnetic spin-label capable of self-assembly from naturally available components would offer a means for studying the in-cell structure and interactions of a protein by electron paramagnetic ...
Structural characterization of the interaction of the polyene antibiotic Amphotericin B with DODAB bicelles and vesicles
(ELSEVIER SCIENCE BV, 2011)
Amphotericin B (AmB) is widely used in the treatment of systemic fungal infections, despite its toxic effects. Nephrotoxicity, ascribed as the most serious toxic effect, has been related to the state of aggregation of the ...
