To prevent oxidative quality changes, a few selected antioxidants, ascorbic acid, or an ascorbic acid plus αtocopherol combination were electrostatically sprayed on the surface of ground beef patties. Color, metmyoglobin, oxidation-reduction potential, lipid oxidation, and volatiles of the samples were determined during the 8 d of aerobic storage. Spraying of ascorbic acid at 500 mg/kg was the ...

Cell differentiation depends mainly on specific mRNA expression. To quantify the expression of a particular gene, the normalisation with respect to the expression of a reference gene is carried out. This is based on the assumption that the expression of the reference gene is constant during development, in different cells or tissues or after treatment. Xenopus laevis studies have frequently use...

Abstract Background Brugada syndrome (BS) is a heritable channelopathy with male predominance. Males (M) seem to have higher risk of arrhythmic events, although, there limited data regarding gender differences in BS. Aim To compare the between genders Portuguese sample BS patients (pts). Methods Single-center retrospective study pts followed by Arrhythmology Department. Pts were divided accordi...

Proof: 1.1. Every mef will be of the form p—> p in virtue of variablesharing. Eefs of the form p —> C and C -+ p, where C is an ef, are ruled out, the first because of the Ackermann property, the second because by modus ponens p would be a theorem. So every eef is a mef, and Lemma 1.1. follows. 1.2. Let A contain two or more propositional variables. In virtue of variable-sharing every ef of A c...

Mobile communication provides access to the outside world without borders everywhere and at any time. The learning method that related to mobile communication technology is known as mobile learning (M-learning). It is a method that communicates learning materials with mobile device technology. The purpose of this method is to increase the interest in learning among students and assist them in o...
