Endophytic fungi producing of esterases: evaluation in vitro of the enzymatic activity using pH indicator
(Sociedade Brasileira de Microbiologia, 2013-09-01)
A sensitive and efficient colorimetric method was optimized for detection of esterase enzymes produced by endophytic fungi for development of High-Throughput Screening (HTS). The fungi were isolated and obtained previously ...
Polarographic determination of loratadine in pharmaceutical preparations
(Elsevier B.V., 1996)
Loratadine, a potent antihistamine drug, is not directly electroreducible at a dropping mercury electrode; however, by means of a nitration procedure it is possible to obtain a nitro-loratadine derivative which has been ...
Role of acystine-based Gemini surfactant ligand in the synthesis of catalytic active silver nanoparticles
(Elsevier Science, 2019-06)
We report the synthesis in water of colloidal silver nanoparticles (AgNP) using a Gemini lipoamino acid surfactant derived from cysteine as a capping agent. The Gemini surfactant interacts with the metal surface mainly in ...

Caracterização e estudo do comportamento térmico dos adutos flunixina-meglumina e diclofenaco-meglumina
(Universidade Estadual Paulista (Unesp), 2010-06-28)
Aduto (do latin Adductus, “atraidos”) é o produto de uma adição direta de duas ou mais moléculas distintas, resultando em um produto de reação simples contendo todos os átomos de todos os componentes, com formação de duas ...

Mechanistic studies of the 'blue' Cu enzyme, bilirubin oxidase, as a highly efficient electrocatalyst for the oxygen reduction reaction
(ROYAL SOC CHEMISTRY, 2010)
The 'blue copper' enzyme bilirubin oxidase from Myrothecium verrucaria shows significantly enhanced adsorption on a pyrolytic graphite 'edge' (PGE) electrode that has been covalently modified with naphthyl-2-carboxylate ...
The role of the Ca2+ binding ligand Asn879 in the function of the plasma membrane Ca2+ pump
(Elsevier Science, 2009-12)
Asn879 in the transmembrane segment M6 of the plasma membrane Ca2+ pump (PMCA human isoform 4xb) has been proposed to coordinate Ca2+ at the transport site through its carboxylate. This idea agrees with the fact that this ...
Maintenance of photosynthetic capacity in flooded tomato plants with reduced ethylene sensitivity
(Wiley Blackwell Publishing, Inc, 2020-05)
Ethylene is considered one of the most important plant hormones orchestrating plant responses to flooding stress. However, ethylene may induce deleterious effects on plants, especially when produced at high rates in response ...
