The interaction of Na+, K+, and phosphate with the gastric H,K-ATPase. Kinetics of E1–E2 conformational changes assessed by eosin fluorescence measurements
(Elsevier Science, 2021-01)
H,K-ATPase and Na,K-ATPase show the highest degree of sequence similarity among all other members of the P-type ATPases family. To explore their common features in terms of ligand binding, we evaluated conformational ...
Determination of cadmium at ultra-trace levels by CPE-molecular fluorescence combined methodology
(Elsevier Science, 2009-10)
A highly sensitive micelle-mediated extraction methodology for the preconcentration and determination of trace levels of cadmium by molecular fluorescence has been developed. Metal was complexed with o-phenanthroline ...
Determination of nickel in cigarettes smoke by molecular fluorescence
(Elsevier Science, 2011-11-08)
Smoking represents the main avoidable cause of disease and death in the world. Cigarette smoke contains over 4700 chemical compounds including 60 known carcinogens. The inhalation of tobacco smoke is one of the most ...
Emprego da imunofluorescência direta no estudo das alterações de mucosa de palato, compatíveis com candidíase atrófica crônica, em indivíduos portadores de próteses dentárias totais muco-suportadas.
(1990-12-01)
Histopathology by hematoxilin-eosin (HE) and periodic acid Schiff (PAS), concomitant direct immunofluorescence (DI) against total human immunoglobulins and against Candida albicans, was effectuated in 25 persons dentures ...

Photophysics of Xanthene Dyes at High Concentrations in Solid Environments: Charge Transfer Assisted Triplet Formation
(Wiley Blackwell Publishing, Inc, 2018-09)
The photophysical behavior of two xanthene dyes, Eosin Y and Phloxine B, included in microcrystalline cellulose particles is studied in a wide concentration range, with emphasis on the effect of dye concentration on ...
Comparison of the kinetics of electron transfer in the diffusion limit for the singlet and triplet quenching of eosin y by quinones
(Wiley Blackwell Publishing, Inc, 2013-11)
Electron transfer (ET) rate constants were determined by means of lifetime measurements for the fluorescence quenching and by laser flash photolysis for the triplet quenching of the dye eosin Y by benzoquinones in acetonitrile. ...
