Abstract: the sizes of vitellogenic oocytes and fecundity of 230 females of manjubas (curimatella lepidura) from the três marias reservoir, river s?o francisco, mg, was determined throughout three years of monthly captures. gravimetric method was used to determine the quantities of vitellogenic oocytes, which were separated from no vitellogenics by weight difference and using water flow. the average diameter of vitellogenic oocytes was 711±44μm. the mean absolute fecundity was 60994.9±27142.7 oocytes per female in stage 2c of maturation (mature). the average fecundity relative to body weight and ovarian weight was 1294.1±437.5 and 8293.8±1961.9 oocytes per gram, respectively. there was no significant difference (p<0.05) between fecundity during the three years of research. high correlation coefficients were found, and the linear and potential models were the most appropriate to express the absolute and relative fecundities, i.e., the higher the maturity degree, higher the fecundity

Abstract: the present study aimed to evaluate the genetic divergence among individuals from four pfaffia glomerata populations collected in the region of paraná river, brazil, based on the study of morphological characters associated with β-ecdysone production. the divergence among 64 individuals was estimated using 14 quantitative morphological characters, including -ecdysone content. data were evaluated considering general mean of the characters, mahalanobis dissimilarity index, upgma grouping method, and pearson correlation. results indicated higher divergence among individuals from different populations and lower divergence among those from the same population. individuals from population 1, collected at the shore of ivaí river, had high β-ecdysone content, with predominance of the following profile, compared to the general mean: lower root dry matter (135.1 g plant-1); earlier anthesis (135.8 days); smaller number of days to senescence of 90% of the leaves (201.4 days); and longer interval between anthesis and senescence (65.6 days). the evaluated characters significantly varied among individuals; nevertheless, the correlation between β-ecdysone production and the evaluated morphological characters could not be evidenced.

Abstract: high levels of von willebrand factor (vwf) have been associated with cardiovascular disease. the a allele of the -1185a/g polymorphism in the 5'-regulatory region of the vwf gene was associated with the highest plasma vwf levels in a normal population. to examine the association between -1185a/g polymorphism and coronary artery disease (cad), 173 brazilian caucasian subjects submitted to coronary angiography were studied. of these, 57 (33%) had normal coronary arteries (control group) and 116 (67%) had cad (patient group). plasma vwf levels were higher in patients (145 u/dl) than in controls (130 u/dl), but the differences were significant only for o blood group subjects. polymerase chain reaction amplification of the 864-bp vwf promoter region followed by accii restriction digestion was used to identify the -1185a/g genotypes. the -1185a allele frequency was 43.1% in patients and 44.7% in controls. allele and genotype frequencies were not significantly different between patients and controls. no association was observed between the -1185a/g genotypes and plasma vwf levels in patients or controls. these results suggest that -1185a/g polymorphism is not an independent risk factor for cad.

Abstract: High levels of von Willebrand factor (vWF) have been associated with cardiovascular disease. The A allele of the -1185A/G polymorphism in the 5'-regulatory region of the vWF gene was associated with the highest plasma vWF levels in a normal population. To examine the association between -1185A/G polymorphism and coronary artery disease (CAD), 173 Brazilian Caucasian subjects submitted to coronary angiography were studied. Of these, 57 (33%) had normal coronary arteries (control group) and 116 (67%) had CAD (patient group). Plasma vWF levels were higher in patients (145 U/dl) than in controls (130 U/dl), but the differences were significant only for O blood group subjects. Polymerase chain reaction amplification of the 864-bp vWF promoter region followed by AccII restriction digestion was used to identify the -1185A/G genotypes. The -1185A allele frequency was 43.1% in patients and 44.7% in controls. Allele and genotype frequencies were not significantly different between patients and controls. No association was observed between the -1185A/G genotypes and plasma vWF levels in patients or controls. These results suggest that -1185A/G polymorphism is not an independent risk factor for CAD.

Abstract: The aim of this study was to investigate dissolved nutrients in a submarine groundwater discharge (SGD) in Flic en Flac lagoon on the west coast of the volcanic island of Mauritius. The SGD enters Flic en Flac lagoon through a thin blanket of unconsolidated sediment through a fracture system and is concentrated along the irregular surface of the buried rock. The results show that the major inputs of dissolved nitrate and phosphate in Flic en Flac lagoon arise from agricultural and domestic sources during periods of heavy rain. Dissolved nitrate (150-470 μg/l) and phosphate (10-115 μg/l) concentrations in the SGD, lagoon and offshore in the Flic en Flac region fell within the range of seawater values in the Pacific region. Rainfall caused dissolved nitrate and phosphate transfer through groundwater conduits in the coralline basement of the lagoon, delivering a significant discharge during the cyclone season in summer. The lagoon is subjected to diffuse SGD flows which may contribute to its high dissolved nutrient values. This will lead to a reduction in the lagoon’s assimilative capacity, exacerbating the problem of excessive nutrient input and associated eutrophication in the lagoon. The submarine groundwater discharge thus merits consideration in Mauritian coastal zone management and similar tropical volcanic lagoonal systems.

Abstract: we studied the effect of oral sirolimus, administered to prevent and treat in-stent restenosis (isr), on the variation of serum levels of inflammatory markers following coronary stenting with bare metal stents. the mean age of the patients was 56 ± 13 years, 65% were males and all had clinically manifested ischemia. serum levels of high sensitivity c-reactive protein (hs-crp) concentration were determined by chemiluminescence and serum levels of all other biomarkers by elisa. one group of patients at high risk for isr received a loading oral dose of 15 mg sirolimus and 5 mg daily thereafter for 28 days after stenting (sir-g). a control group (cont-g) was submitted to stenting without sirolimus therapy. the increase in hs-crp concentration was highest at 24 h after stenting in both groups. a significant difference between sir-g and cont-g was observed at 4 weeks (-1.50 ± 5.0 vs -0.19 ± 0.4, p = 0.008) and lost significance 1 month after sirolimus discontinuation (-1.73 ± 4.3 vs -0.01 ± 0.7, p = 0.0975). a continuous fall in mmp-9 concentration was observed in sir-g, with the greatest reduction at 4 weeks (-352.9 ± 455 vs +395.2 ± 377, p = 0.0004), while a positive variation was noted 4 weeks after sirolimus discontinuation (227 ± 708 vs 406.2 ± 472.1, p = 0.0958). sir-g exhibited a higher increase in p-selectin after sirolimus discontinuation at week 8 (46.1 ± 67.9 vs 5.8 ± 23.7, p = 0.0025). these findings suggest that the anti-restenotic actions of systemic sirolimus include anti-proliferative effects and modulation of the inflammatory response with inhibition of adhesion molecule expression.

Abstract: Devastating earthquakes like the 1944 San Juan earthquake reflect active deformation in western Argentina. Although the earthquake caused considerable damage to San Juan, the source of the earthquake remains uncertain. Potential source faults occur in the thin-skinned fold-and-thrust belt Precordillera province and in the thick-skinned Sierras Pampeanas province, to the west and east, respectively of Sierra de Villicum, a thrust sheet in the eastern Precordillera northwest of San Juan. Sierra de Villicum is a west-vergent thrust sheet bound on the northwest by the Villicum thrust, which juxtaposes a southeast dipping panel of Cambro-Ordovician and Neogene strata in the hanging wall with Neogene red beds in the footwall. A series of Late Pleistocene fluvial terraces developed across the Villicum thrust show no evidence of active fold or fault deformation. Terraces are deformed by active folds and faults in the middle of the southeastern flank of the Sierra de Villicum thrust sheet. A southeast-facing, southwest-plunging monocline characterizes the Neogene red beds in the region of active folding. Co- and post-seismic surface rupture along roughly 6 km of the La Laja fault in 1944 occurred in the limb of the monocline. Evidence that surface deformation in the 1944 earthquake was dominated by folding includes terrace′s fold geometry, which is consistent with kink-band models for fold growth, and bedding-fault relationships that indicate that the La Laja fault is a flexural slip fault. A blind basement reverse fault model for the earthquake source and for active deformation reconciles the zone of terrace deformation, coseismic surface rupture on the La Laja fault, refolding of the Villicum thrust sheet, a basement arch between the Precordillera and eastern Precordillera, and microseismicity that extends northwestward from a depth of ~5 km beneath Sierra de Villicum to ~35 km depth. Maximum horizontal shortening rate is estimated to be ~3.0 mmyr-1 from the terrace fold model and correlation of the terraces with dated terraces located to the southwest of the study area. Basement rocks beneath Cerro Salinas, another eastern Precordillera thrust sheet to the southwest, are also characterized by an east-facing monoclinal geometry, which suggests that blind thrust faulting on east-vergent basement faults represents a significant, underappreciated seismic hazard in western Argentina. La deformación activa en el oeste de Argentina está reflejada por terremotos devastadores como el sismo de San Juan en 1944. Aunque el terremoto causó un da o considerable a San Juan,

Arquivo Brasileiro de Medicina Veterinária e Zootecnia , 1999, DOI: 10.1590/S0102-09351999000200003
Abstract: for 53 grower/finisher-only swine operations that participated in the united states national animal health monitoring system 1995 national swine study, mortality among finisher pigs ranged from 0 to 12.0% over a 6-month period. twenty-six (49.1%) had <2% mortality, and 27 (50.9%) had >2% mortality. nine (17.0%) operations experienced >4% mortality. fisher's exact test revealed that operations with all-in all-out management were significantly more likely to have <2% mortality than operations with continuous management, and that operations where all finisher pigs came from farrowing units belonging to the operation (either on-site or off-site) were significantly more likely to have <2% mortality than operations where >1 grower/finisher pig came from another source. larger operations (where >900 pigs entered the grower/finisher phase) practiced all-in, all-out management more frequently than smaller operations, and had a lower mean percent mortality than smaller operations. diagnosis of salmonella in finisher pigs performed at a laboratory or by a veterinarian in the 12 months prior to interview was associated with both increased percent mortality and increased percent mortality per day.
