Castoldi, Renata;Charlo, Hamilton César de O;Dalpian, Tagli;Melo, Danilo M;Botelho, Adelita P;Braz, Leila T;
Horticultura Brasileira , 2012, DOI: 10.1590/S0102-05362012000200005
Abstract: lettuce is the most consumed leafy vegetable in brazil. however, its production has faced increasing difficulties mainly due to the infestation of producing areas with bremia lactucae, the causing agent of downy mildew, the worst disease in lettuce. the aim of this study was to identify b. lactucae races occurring in lettuce producing areas of s?o paulo state, during 2008 and 2009. lettuce leaf samples containing b. lactucae sporangia were collected in the major lettuce producing areas of s?o paulo. each sample was considered an isolate. after the multiplication of sporangia in the susceptible cultivar solaris, with subsequent inoculation in the differentiating cultivars, the evaluations were performed on the same day of the first sporulation in the susceptible cultivar 'cobham green (dm 0)'. in 2008 one new b. lactucae code was identified. spbl:05 was the denomination proposed to it. in 2009 one another b. lactucae code was identified, that is, 63/63/02/00, whose denomination was proposed to be spbl:06.

Error bounds for semi-Galerkin approximations of nonhomogeneous incompressible fluids
P. Braz e Silva,M. A. Rojas-Medar
Mathematics , 2005,
Abstract: We consider the spectral semi-Galerkin method applied to the nonhomogeneous Navier-Stokes equations. Under certain conditions it is known that the approximate solutions constructed through this method converge to a global strong solution of these equations. Here, we derive an optimal uniform in time error estimate in the $H^1$ norm for the velocity. We also derive an error estimate for the density in some spaces $L^r$.

Abstract: Plants respond to pathogens and insect attacks by inducing and accumulating a large set of defense-related proteins. Two homologues of a barley wound-inducible protein (BARWIN) have been characterized in sugarcane, SUGARWIN1 and SUGARWIN2 (sugarcane wound-inducible proteins). Induction of SUGARWINs occurs in response to Diatraea saccharalis damage but not to pathogen infection. In addition, the protein itself does not show any effect on insect development; instead, it has antimicrobial activities toward Fusarium verticillioides, an opportunistic fungus that usually occurs after D. saccharalis borer attacks on sugarcane. In this study, we sought to evaluate the specificity of SUGARWIN2 to better understand its mechanism of action against phytopathogens and the associations between fungi and insects that affect plants. We used Colletotrichum falcatum, a fungus that causes red rot disease in sugarcane fields infested by D. saccharalis, and Ceratocystis paradoxa, which causes pineapple disease in sugarcane. We also tested whether SUGARWIN2 is able to cause cell death in Aspergillus nidulans, a fungus that does not infect sugarcane, and in the model yeast Saccharomyces cerevisiae, which is used for bioethanol production. Recombinant SUGARWIN2 altered C. falcatum morphology by increasing vacuolization, points of fractures and a leak of intracellular material, leading to germling apoptosis. In C. paradoxa, SUGARWIN2 showed increased vacuolization in hyphae but did not kill the fungi. Neither the non-pathogenic fungus A. nidulans nor the yeast S. cerevisiae was affected by recombinant SUGARWIN2, suggesting that the protein is specific to sugarcane opportunistic fungal pathogens.

Abstract: the present descriptive study aimed to elucidate the morphoanatomical and developmental features of fruits, seeds and seedlings of pseudima frutescens (sapindaceae), which is a tree species. flowers and fruits at different developmental stages were used in the descriptions. a hundred seeds were set in germination boxes (four seeds per box) on filter paper moistened with distilled water and kept at 25+1oc to observe seedling germination and development. the fruit of this species, which has two seeds, is a round obcordate capsule, lobed, reddish-orange on the outside and orange on the inside. the seed exalbuminous, is ovoid, black and shiny; the embryo, occupying all the inside of the seed, has fleshy cotyledons and a short hypocotyl-radicle axis. the seedling is cryptocotyledonary and the germination, which is hypogeal, occurred under light conditions and started from the fifth day after sowing. by the eighth day, the root measured 17mm in length, showing numerous absorbent hairs on its full extent. after 14 days, the epicotyl (slightly green) emerged. the seedling exhibited, after 30 days, two pairs of compound eophylls and, by the sixtieth day, the primary root measured 12cm long with many lateral roots; the epicotyl was 9cm long and had six expanded leaves. in view of the fact that the development of the seedling is considered relatively quick, p. frutescens may be indicated for the use in the recovery of degraded areas.

ZooKeys , 2011, DOI: 10.3897/zookeys.157.1083
Abstract: Body size is correlated with many species traits such as morphology, physiology, life history and abundance as well; it is one of the most discussed topics in macroecological studies. The aim of this paper was to analyze the body size distribution of Chrysomelidae, caught with Malaise traps during two years in four areas with different levels of conservation in the Araucaria Forest, Paraná, Brazil, determining if body size is a good predictor of abundance, and if body size could be used to indicate environmental quality. Body size was considered the total length of the specimen from the anterior region of head to the apex of abdomen/elytron. Measurements were taken for up to ten specimens of each species for each area and for all specimens of those species represented by fewer than ten individuals. The highest abundance and richness of Chrysomelidae were obtained in the lowest body size classes. This herbivorous group showed a trend toward a decrease in body size with increasing abundance, but body size was not a good predictor of its abundance. There was a trend toward a decrease in body size from the less to the most conserved areas; however, the definition of a pattern in successional areas not seems to be entirely clear.
Coronary fat content evaluated by morphometry in patients with severe atherosclerosis has no relation with serum lipid levels

Abstract: the relationship between lipid serum levels and coronary atherosclerotic plaque fat content was studied in 51 necropsy patients. serum lipids were measured by standard techniques, during life, in the absence of lipid-lowering drugs. intima, intimal fat and media areas were measured using a computerized system in cryosections of the odd segments of the right, anterior descending and circumflex coronary arteries stained with sudan-iv. mean intimal and lipid areas were 5.74 ± 1.98 and 1.22 ± 0.55 mm2 (22.12 ± 8.48%) in 26 cases with high cholesterol (3200 mg/dl) and 4.98 ± 1.94 and 1.16 ± 0.66 mm2 (22.75 ± 9.06%) in 25 cases with normal cholesterol (<200 mg/dl; p > 0.05). patients with high levels of low-density lipoprotein (3130 mg/dl, n = 15) had a higher intima/media area ratio than those with normal levels of low-density lipoprotein (<130 mg/dl, n = 13, p < 0.01). no significant difference in the morphometrical variables was found in groups with high or low serum levels of triglycerides (3200 mg/dl, n = 13 vs <200 mg/dl, n = 36) or high-density lipoprotein (335 mg/dl, n = 11 vs <35 mg/dl, n = 17). the association between the morphological measurements and serum levels of cholesterol, its fractions, and triglycerides was also tested and the correlation coefficients were low. although high cholesterol is a risk factor, we show here that in patients with severe atherosclerosis blood cholesterol and triglyceride levels seem to have little influence on coronary lipid content, indicating that other factors may contribute to arterial lipid deposition and plaque formation.
