| Tendon rupture is a very frequent accident involving average people and high-performance athletes. Clinical studies describe tendon recovery as a painful and slow process involving different biochemical and histological events. Ascorbic acid (AA) is a potent antioxidant as well as an important cofactor for collagen synthesis. In the current study, we evaluated if local treatment with AA is able to promote tendon repair in tenotomized rats. Animals were submitted to Achilles tendon rupture followed by surgical suture. Control and AA groups received in loco injection of saline solution (0.9% NaCl) and 30 mM AA, respectively. Histological and functional recovery of Achilles tendon tissue was evaluated at 7, 14, and 21 days post-surgery. Hematoxylin/eosin... |

| N-acetylcysteine (NAC) inhibits nociceptive transmission. This effect has been associated partly with its antioxidant properties. However, the effect of NAC on the levels of lipid hydroperoxides (a pro-oxidant marker), content of ascorbic acid (a key antioxidant molecule of nervous tissue) and total antioxidant capacity (TAC) is unknown. Thus, our study assessed these parameters in the lumbosacral spinal cord of rats with chronic constriction injury (CCI) of the sciatic nerve, one of the most commonly employed animal models of neuropathic pain. Thirty-six male Wistar rats weighing 200–300 g were equally divided into the following groups: Naive (rats did not undergo surgical manipulation); Sham (rats in which all surgical procedures involved in CCI were... |

| In this study, the effects of cadmium (Cd) on lipid peroxidation, electrolyte leakage, protein oxidation, ascorbate peroxidase (APX; E.C. 1.11.1.11), catalase (CAT; E.C. 1.11.1.6) and superoxide dismutase (SOD; E.C. 1.15.1.1) activities, and ascorbic acid, non-protein thiol groups and total soluble protein contents in cucumber seedlings (Cucumis sativus L.) were investigated. Seedlings were grown in vitro in an agar-solidified substrate containing four Cd levels as CdCl2 (0, 100, 400, and 1000 µmol L-1) for 10 d. The lowest Cd level decreased the malondialdehyde concentration. Electrolyte leakage increased only at 1000 µmol Cd L-1, whereas protein oxidation and total soluble protein content were enhanced at 400 and 1000 µmol Cd L-1. Activity of APX was... |

Cien. Inv. Agr. 40(3): 537-545. Economically, blueberry (Vaccinium corymbosum) has become a very important fruit crop in Chile, and stem canker (Neofusicoccum parvum) has frequently been observed as a major disease. The symptoms are characterized by partial or total death of the foliage associated with extensive reddish-brown canker lesions at the base of the stems. Pruning wounds appear to be the main infection route. In this study, fungicide pastes and biological control agents were evaluated for their effectiveness as pruning wound-protectants against N. parvum.... |

Quality, bioactive compounds, and antioxidant activity of serrano chili peppers cultivated in volcanic rock-vermicompost and nutrient solutions. Cien. Inv. Agr. 42(3): 375-384. The concentration of antioxidant compounds, the antioxidant activity, physical quality characteristics, and the yield of serrano chilies (Capsicum annuum L.) are affected by agricultural practices, such as the use of vermicompost in containers combined with chemical fertilizers, the investigations of which have focused on yield. A study was performed to determine whether vermicompost mixed with volcanic rock and the ionic composition of the nutrient solution affect... |

| Objetivou-se neste estudo avaliar a inclusão de ractopamina e sua associação com as vitaminas antioxidantes C e E em dietas de suínos em terminação durante 28 dias antes do abate sobre o desempenho, as características de carcaça e a qualidade da carne. Quarenta e oito suínos da linhagem Agroceres PIC (24 machos castrados e 24 fêmeas) foram distribuídos em delineamento experimental de blocos casualizados, em esquema fatorial 3x2, com três dietas: controle; controle + 10ppm de ractopamina; controle + complexo (0,05%) de ractopamina com vitaminas antioxidantes (10ppm de ractopamina + 200mg de vitamina E + 100mg de vitamina C kg-1 de ração) e dois gêneros (machos castrados e fêmeas). Foram avaliados o consumo de ração, o ganho de peso e a conversão alimentar... |
