The TEPA-induced toxic effect was alleviated when Cu was added with TEPA. Our findings suggest that the Cu transport system plays an important role in the porcine follicular development process and that the Cu deficiency negatively affects porcine oocyte maturation, as well as their subsequent developmental competence. 1 Introduction
When tumors reached approximately 3 mm in diameter, mice were randomized to experimental groups that received either saline (control), TEPA, or DC. TEPA was administered up to 7 days by oral gavage at a nontoxic dose typically used to control Cu accumulation in vivo . Alternatively, DC was given intravenously and tumors collected 24 …

Under the same loadings of TETA/TEPA, the samples modified by TEPA exhibited better CO 2 adsorption capacities than the samples modified by TETA because TEPA has one more amine group than TETA in the molecule. The results also indicated that the samples had good adsorption capacities at the loadings ranging from 30% to 35%.
