The use of stable isotopes for authentication of gadoid fish species
(European Food Research and Technology, 2011-01-01) [Artigo]
The rise of processed seafood in international trade has increased the feasibility of fish species substitution. Gadidae fish species are sold commercially as salted fish, and differences in price between fish of different ...
Determinação da razão isotópica delta13C em bebidas comerciais a base de laranja
(Ciência e Agrotecnologia, 2009-08-01) [Artigo]
Conduziu-se este trabalho, com o objetivo de quantificar a proporção de carbono de fonte C3 (suco de laranja) e carbono C4 (açúcar de cana) em bebidas comerciais à base de laranja. Foram analisadas isotopicamente 33 ...
Turnover do carbono em sangue e plasma, nas fases crescimento e postura, de codornas japonesas (Coturnix coturnix japonica)
(Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014-12-01) [Artigo]
The study aimed to evaluate the turnover of 13C in the blood and plasma of Japanese quail using the technique of stable isotopes to obtain the level of isotopic equilibrium that will be the foundation for studies of ...
Growth and photosynthetic down-regulation in Coffea arabica in response to restricted root volume
(Functional Plant Biology, 2006-01-01) [Artigo]
Coffee (Coffea arabica L.) plants were grown in small (3-L), medium (10-L) and large (24-L) pots for 115 or 165 d after transplanting (DAT), which allowed different degrees of root restriction. Effects of altered source : ...
Carbon-13 and Nitrogen-15 Turnover in Serum of Bubaline Donors of Biological Material for Medical Use
(Toxicon, 2012-08-01) [Resumo]
The use of stable isotopes to investigate the effects of supplemental lysine and methionine on protein turnover and amino acid utilization in pacu, Piaractus mesopotamicus, juveniles
(Aquaculture, 2014-09-20) [Artigo]
The present study investigated the use of the stable isotope technique to evaluate the effects of nutritionally deficient diets, supplied or not with lysine and/or methionine, on the isotopic turnover of bio-elements (carbon ...
Drought tolerance is associated with rooting depth and stomatal control of water use in clones of Coffea canephora
(Annals of Botany, 2005-07-01) [Artigo]
center dot Background and Aims Drought is a major environmental constraint affecting growth and production of Coffea canephora. Selection of C. canephora clones has been largely empirical as little is known about how clones ...
Muscle delta C-13 change in Nile tilapia (Oreochromis niloticus): Effects of growth and carbon turnover
(Comparative Biochemistry and Physiology B: Biochemistry & Molecular Biology, 2006-09-01) [Artigo]
The contribution of growth and turnover to the muscle delta C-13 change process was investigated using mathematical models which associate delta C-13 change to time of intake of a new diet or increase in body mass. Two ...
Análise isotópica (δ13c) e legalidade em néctares de uva
(Boletim Centro de Pesquisa de Processamento de Alimentos, 2010-12-01) [Artigo]
The aim of this work was to develop an isotopic analysis method to quantify the carbon of C3 photosynthesis cycle in grape nectar and to identify the commercial beverages in disagreement to the Brazilian Ministry of ...
Glutamina e turnover do carbono da mucosa intestinal de leitões desmamados
(Revista Brasileira de Zootecnia, 2010-12-01) [Artigo]
Um experimento foi conduzido para verificar a influência da glutamina no turnover do carbono na mucosa intestinal de leitões desmamados. Nove matrizes receberam dietas compostas basicamente de plantas do ciclo fotossintético ...
