Reproduction of Asterina stellifera was studied in two populations from the Cabo Frio region, southeastern Brazil. One was located in an intertidal seagrass
flat at Japonês Island (1994–1995); the second was on a sublittoral rocky shore at Pontal beaches (1999–2000). Reproductive
cycle was studied at monthly intervals by organ indices and histological examinations of gonads. Although these two populations
were studied in different habitats and at different times, the periodicity of the annual reproductive cycle was very similar
for the two populations. The highest gonad index (GI) values were found in August/September (late winter), followed by a drop
in GI values, indicating spawning. The GI and pyloric caeca index (PCI) tended to have an inverse relationship in both populations,
but it was only statistically significant in the rocky-shore population. Gametogenesis in the two populations was described
and roughly confirmed the reproductive cycles determined by GIs.

The aim of this study was to evaluate the detection of fetal structural abnormalities by the 11–14 week scan. 2853 pregnant women were submitted to a routine ultrasound scan between the 11th and 14th week and the fetal skull, brain, spine, abdominal wall, limbs, stomach and bladder were examined. Following the scans the patientes were examined in the second or third trimester of pregnancy. An isolated increased nuchal translucency was not considered an abnormality. However, these patients had an early echocardiography assessment. Fetal structural abnormalities were classified as major or minor and of early or late onset. A total of 130 (4.6%) defects were identified and 29 (22.3%) of these were diagnosed at the 11–14 week scan, including nine cardiac defects associated with increased nuchal translucency. The antenatal ultrasound detection rate was 71.5%, and 31.2% were detected in the first-trimester assessment. 78.8% of the major defects were diagnosed by the prenatal scan and 37.8% by the 11–14 week scan. Fetal structural abnormalities at the 11–14 week scan were detected in approximately 22.3% of the cases, therefore, a second-trimester anomaly scan is important in routine antenatal care to increase the prenatal detection of fetal defects.

This survey was done to register information of cerrado's medicinal plants sellers, who trade in downtown Anápolis (Brazil). The information obtained was pertaining to medicinal purposes, the most used portion of the plants, ecological lore and the best selling plants. A cluster analysis was performed to group the plants by medicinal use and by their chemical composition, obtained in the current literature. To verify if differences in chemical compounds correspond to differences in medicinal use, a Mantel test was applied to assess the correlation in those grouping. The results showed a low but significant correlation between medicinal use and chemical composition of the plants, nevertheless, there is still little published information on the pharmacological potential of cerrado's plant. Trade of cerrado's medicinal plants has local economic importance for a low income and illiterate population and the urbanization of the activity caused the loss of some traditional knowledge, like ecological information about the plants. A traveling salesman of medicinal plants (raizeiro) seems to have the most traditional lore, but he was not found to the interview. The excessive use of roots for medicinal purposes can be a threat to cerrado biome coupled with other human pressures in this ecosystem. Traditional knowledge of medicinal plants is endangered as much as the ecosystem that originated it. 相似文献

Increased anthropogenic delivery of nutrients to water bodies, both freshwater and estuarine, has caused detrimental changes in habitat, food web structure, and nutrient cycling. Nitrogen-stable isotopes may be suitable indicators of such increased nutrient delivery. In this study, we looked at the differences in response of macrophyte delta15N values to anthropogenic N across different taxonomic groups and geographic regions to test a stable isotopic method for detecting anthropogenic impacts. Macrophyte delta15N values increased with wastewater input and water-column dissolved inorganic nitrogen (DIN) concentration. When macrophytes were divided into macroalgae and plants, they responded similarly to increases in wastewater N, although macroalgae was a more reliable indicator of both wastewater inputs and water-column DIN concentrations. Smooth cordgrass (Spartina alterniflora Loisel.) Delta15N increased uniformly with wastewater inputs across a geographic range. We used the relationship derived between S. alterniflora and relative wastewater load to predict wastewater loads in locations lacking quantitative land use data. The predictions matched well with known qualitative information, proving the use of a stable isotopic method for predicting wastewater input. 相似文献
