| BACKGROUND: Accumulating evidence indicates that reactive oxygen species (ROS) are an important etiological factor for the induction of dermal papilla cell senescence and hair loss, which is also known alopecia. Arctiin is an active lignin isolated from Arctium lappa and has anti-inflammation, anti-microbial, and anti-carcinogenic effects. In the present study, we found that arctiin exerts anti-oxidative effects on human hair dermal papilla cells (HHDPCs). RESULTS: To better understand the mechanism, we analyzed the level of hydrogen peroxide (H2O2)-induced cytotoxicity, cell death, ROS production and senescence after arctiin pretreatment of HHDPCs. The results showed that arctiin pretreatment significantly inhibited the H2O2-induced reduction in cell... |

| We assessed the accumulation dynamics of forage and its components in Elephant grass cv. Napier (Pennisetum purpureum Schum.) that were subjected to three post-grazing height treatments (30, 50, and 70 cm) from February through May 2009 (experiment one) and December 2009 through May 2010 (experiment two). In experiment one, the grazing events started when the light interception by the canopy reached 95%. The same was adopted for experiment two, except for the first grazing event, which was based on the height of the apical meristems of basal tillers. The experimental design for both experiments was a randomized complete block with three replications. The pastures that were managed at a post-grazing height of 30 cm exhibited lower rates of leaf and stem... |

| The effect of nitrogen (N) fertilization (0, 50, 100 and 200 kg N ha-1) on forage yield and morphogenesis of Axonopus aureus was evaluated in the savannas of Roraima State, Brazil. The experimental design was in randomized blocks with three replicates. The grass showed high responsiveness to N fertilization. Dry weight (DW) yield, morphogenetic and structural traits and forage quality were positively affected by N fertilization. The effects of N fertilization on DW yield, N content, leaf appearance rate, leaf elongation rate, number of live leaves/tiller, final leaf length and leaf area index were quadratic and maximum values were estimated with application of 168.8 (2,181 kg ha-1); 124.8 (21.1 g/kg); 158.5 (0.163 leaf/day per tiller); 172.3 (2.75... |

| Aspects related to the longevity and oviposition of Ophyra albuquerquei Lopes, 1985 are studied. Males had a mean lifespan longer than females (40.24 vs. 33.15 days, respectively), while still possessing qualitative advantages during this period. Females O. albuquerquei were fed on powdered milk, fish flour, refined sugar and water, and provided fish flour and moistened sawdust for oviposition. The length of the oviposition period for females was 46.75 days, and most of the deposition of the eggs occurred in the first days of the colony. Females completed 50% of their egg deposition by Day 16, seven days before the large last mortality peak and about 12 days after the first oviposition in the colony. Females deposited an average of 184 eggs per individual.... |

| The 'Niagara Rosada' grape is the main Brazilian table grape belonging to the Labrusca family. It develops medium, cylindrical and compact bunches with berries presenting a pinkish skin and a foxy flavor that is valued in the Brazilian market. These berries are tender and have a pedicel-berry connection provided by the vascular bundles and surrounding skin. This cultivar is very susceptible to berry drop mainly caused by vibration and senescence. The objective of this study was to evaluate the temporal mechanical behavior of the pedicel-berry detachment, using resistance indexes extracted from traction force-deformation curves. Test results showed two different detachment types. In the first one, which exhibited higher average resistance, a considerable... |

| The morphogenesis of giant missionary grass (Axonopus jesuticus x A. scoparius) was evaluated in this study in response to the application of 0, 40, 80, 120, 160, and 200m³ ha-1year-1 of pig slurry, calculated to provide 0, 100, 200, 300, 400, and 500kg N ha-1year-1, respectively. The experiment was carried out in the field, at Chapecó, Santa Catarina, Brazil, in 2010-2011. The doses were fractioned in four applications, performed after the pasture cuttings, during the growth season of the grass. Morphogenetic evaluations were performed weekly between 10/26/2010 and 12/07/2010 (spring), 12/14/2010 and 01/11/2011 (late spring/early summer), 01/18/2011 and 02/07/2011 (summer), and 02/15/2011 and 03/21/2011 (late summer). The leaf senescence, leaf elongation,... |

| The aim of this study was to determine quality changes in petioles of self-blanching celery (Apium graveolens), cv. Golden Boy, harvested at 80, 87, 94, 101, 108, 115, 122 and 129 days after-transplanting (DAT). Total weight (TW), total length (TL), number of leaves per plant (LN) and by plant zone (external, LNZ E; middle, LNZ M; internal, LNZ I), and petiole length (PL) were evaluated at each harvest time. Petioles quality of each zone in the plant were analyzed in terms of: color (hue angle), texture (cutting force), total soluble solids content (TSS) and titratable acidity (TA). The petioles also were sensorially evaluated by descriptive analysis considering visual characteristics (flexibility, hollowness), flavor (typical flavor and odor) and texture... |

| Aroma volatiles and fruit quality traits at harvest or after senescence were determined in a collection of near-isogenic lines (NILs) with different climacteric behavior (two non-climacteric NILs more the parental non-climacteric ´Piel de sapo´ and the rest climacteric). Data were analyzed by partial least squares discriminant analysis. In senescent fruit, four ester volatiles (particularly benzyl acetate) helped to discriminate between climacteric and non-climacteric NILs. Aroma volatiles were more efficient for discriminating by senescent or climacteric behavior than fruit quality traits, and flavor traits (dry matter, soluble solids content, titratable acidity, and individual sugars and organic acid content) were more efficient than using other major... |
