Avaliaçãeo ultrassonográfica da dinâmica folicular ovariana de jumenta (equus asinus) durante o ciclo estral

The ovarian activity was accessed by ultrasound throughout 10 estrous cycles from Jennies (Marchador Brasileira). Daily ultrasound examinations were performed and the dada was retrospectively studied based on daily identification of each follicle detected. Blood samples were collected every 24 hours from ovulation (D0) until the next identified ovulation. The follicles measuring 11mm were detected and their mean diameter was registered daily using an ovarian map and permitting a retrospective evaluation of the dada, which represented the follicular growth dynamics. One and two major follicular waves were detected in six (60%) and four (40%) cycles respectively from ten estrous cycles in the present study. The primary wave emergency and follicle deviation from the cycles observed during the present study with one major follicular wave occurred at day 10.2 ± 0.75 and at day14.1 ± 0.81 and for cycles with two major waves, those events occurred at 9.0 ± 2.0 and 14.0 ± 1.15 days after ovulation. The maximum diameter of the dominant follicle at the cycles with one and two follicular waves were 37.2 ± 3.35 mm and 37.3 ± 1.1, respectively. The mean intervals from two ovulations were 23.0 ± 1.79 and 22.3 ± 1.26 days when observed in cycles with one and two major follicular waves. The maximum diameter of the dominant follicle was slightly smaller when double ovulations were observed if compared with the single ovulations (P > 0.05). It can be concluded that wave emergency period is observed around 9.6 days of the estrous cycle and the occurrence of deviation can be observed on day 14 of the estrous cycle.

A síndrome do hiperestímulo ovariano não influencia os resultados clínicos após ciclos de descongelamento de embriões provenientes de ciclos de ICSI

Objective: The objective of this study was evaluate if the embryos cryopreservation from OHSS patients Intracytoplasmic Sperm Injection (ICSI) cycles could be influence the clinical outcomes when compared to patients who receive oocytes from donors but the endometrium was not prepared and the embryos were cryopreserved. Methods: Fifty eight couples submitted to ICSI cycles in which 26 with OHSS clinical manifestation (OHSS group) and 32 couples who have received oocytes from donors (control group). The embryos were frozen on day+2 or +3of development. All patients included in this study had embryos crypreserved before the transfer, and in the thawing cycle, only the endometrium preparation was performed. The embryo survival, implantation, pregnancy and miscarriage rates were evaluated in the embryo thawing cycle. Results: There was no difference among the groups in relation to fertilization rate (OHSS: 71.89% ± 15.45, Control: 79.75% ± 21.68, p= 0.234), survival embryos rate (OHSS: 68.85 ± 21.10, Control: 59.53 ± 36.79, p= 0.233), high quality embryos rate (OHSS: 25.20 ± 23.90, Control: 27.40 ± 30.30, p= 0.760), implantation rate (OHSS: 17.9 ± 26.9, Control: 12.5 ± 23.7, p= 0.435), pregnancy rate (OHSS: 38.50, Control: 28.60, p= 0.441) and miscarriage rate (OHSS: 40.00, Control: 25.00, p= 0.332). Conclusion: Our findings suggest that clinical outcomes in freeze and thawing cycles were not affected by the presence of ovarian hyperstimulation syndrome clinical manifestation after controlled ovarian stimulation.

Variabilidade temporal e meridional de estimativas de Satélite da concentração de clorofila superficial na plataforma continental brasileira

Forecast of biological consequences of climate changes depend on both long-term observations and the establishment of carbon budgets within pelagic ecosystems, including the assessment of biomasses and activities of all players in the global carbon cycle. Approximately 25% of oceanic primary happen over continental shelves, so these are important sites for studies of global carbon dynamics. The Brazilian Continental Shelf (BCS) has sparse and non-systematic in situ information on phytoplankton biomass, making products derived from ocean color remote sensing extremely valuable. This work analyzes chlorophyll concentration (Chl) estimated from four ocean color sensors (CZCS, OCTS, SeaWiFS and MODIS) over the BCS, to compare Chl and annual cycles meridionally. Also, useful complementary ocean color variables are presented. Chl gradients increased from the central region towards north and south, limited by estuarine plumes of Amazon and La Plata rivers, and clear annual Chl cycles appear in most areas. In southern and central areas, annual cycles show strong seasonal variability while interannual and long-term variability are equally important in the remaining areas. This is the first comparative evaluation of the Chl over the BCS and will aid the understanding of its long-term variability; essential initial step for discussions of climate changes.

Ant diversity in a sugarcane culture without the use of straw burning in southeast, são paulo, Brazil

Problem statement: One of the current requirements of agroecosystem management is the maintenance of biodiversity. Manual sugarcane harvesting with the previous burning of straw has been gradually replaced by mechanical harvesting in Brazil. However, the diversity of Formicidae, which can be a natural pest controller, has not been studied in this new system yet. Approach: This study was carried out to assess the diversity of ants in an exclusively mechanically harvested sugarcane culture based on the hypothesis that species richness and abundance will increase with the deposition of straw in this culture system. Ants were sampled using pitfall traps in six sugarcane cultivars during three consecutive harvest cycles. Results: A total of 8,139 ants, distributed in 39 species, were collected. Richness, abundance and diversity differed between harvest cycles, especially in the first cycle, when the soil did not have any straw and in the two last cycles and the straw layer was about 10-15 cm thick. The communities found in the second and third cycles were similar and the maintenance of straw in the culture contributed to a greater species diversity, particularly of generalist predaceous taxa, which may contribute to the natural control of pests. Conclusion: The diversity of ants increased with straw deposition, including of taxa that may be beneficial to the sugarcane culture. However, new studies of the predatory and competition relations in this agroecosystem are necessary. © 2010 Science Publications.

Características morfogênicas e estruturais do capim-xaraés submetido a intesidades de pastejo

The aim of this study was to evaluate the effects of residual leaf area index (rLAI), years of evaluation and grazing cycles on the morphogenetic and structural characteristics of xaraés palisadegrass subjected to grazing intensities in two summers (years of evaluation). The experiment was carried out at the Universidade Estadual Paulista Júlio de Mesquita Filho - UNESP, Campus de Jaboticabal, São Paulo, Brasil and the intensities of grazing were defined by four rLAI: 0.8, 1.3, 1.8 and 2.3. When the canopy intercepted 95% of incident light, the animals were placed on the pasture for grazing and kept until the rLAI target has been reached. Pastures were grazed by non-lactating Holstein cows (Bos Taurus Taurus L.), using the technique of mob-stocking. The morphogenetic and structural characteristics of xaraés palisadegrass respond effectively to weather conditions. There is variability in morphogenetic and structural characteristics in response to years and grazing cycles within years.
