(1973)The radioprotective ability of L-tryptophan, tryptamine, 3-indoleacetic and indole (10−4 m), on UV and gamma irradiated DNA (10−4 m) is studied. UV radioprotection is accomplished in the following order of efficiency: ...
-
(1993)EPR has been used to investigate the radicals postulated as intermediates in the intramolecular electron transfer and dehalogenation of p-nitrobenzyl bromide (p-NBBr) in DMSO and DMFA at room temperature. The electrochemical ...
-
(Instituto de Tecnologia de Alimentos - ITAL, 2015)Betalains are fruit pigments possessing health-giving properties. To isolate the pigments, the juice must be separated from the fruit matrix, which contains biopolymers. The aim of this study was to clarify cactus pear ...
-
(Taylor and Francis Inc., 2016)A modification to the traditional synthesis of reduced silver metal nanoparticles with hydroxylamine hydrochloride is proposed. The new colloid, obtained by decreasing the concentration of hydroxide and chloride ions, is ...

-
(Elsevier Ltd, 2018)© 2018 Elsevier Ltd To identify processing conditions that better maintain palm ruff quality attributes, high hydrostatic pressure (HHP) was applied to pre- and post-rigor fillets. Physical parameters as whiteness index ...
-
(Academic Press Inc., 2015)In the heart, insulin controls key functions such as metabolism, muscle contraction and cell death. However, all studies have been focused on insulin action during reperfusion. Here we explore the cardioprotective action ...
-
(Oxford University Press, 1975)AUTHORS' SYNOPSIS: The mechanical effects of heart contraction on coronary flow were studied in the dog heart by implanting vessels in the subendocardial and subepicardial layers of the left ventricular wall and perfusing ...
-
(NLM (Medline), 2018)Background: Numerous studies have proposed the use of fluorescent semiconductor nanoparticles or quantum dots (QDs) as novel tools to label cells and tumors. However, QD applications are limited by their toxicity in ...
