Biologia reproductiva de la saraquita Ramnogaster arcuata (Jenyns, 1842) del estuario del Rio de la Plata. OceanDocs
Rodrigues, K.A..
The reproductive biology of Ramnogaster arcuata inhabiting waters of the Rio de la Plata estuary (Argentina - Uruguay) was studied by using macroscopic and histological analysis of ovaries. R. Arcuata specimens were collected from two research cruises of the National Institute of Fisheries Research and Development (INIDEP) carried out in June 1998 and June 1999. During these surveys, bottom salinity and temperature data were also registered. In addition, information about annual catches of this species in the Rio de la Plata, obtained from different INIDEP cruises performed during the last ten years, was analyzed. During winter, a prevalence of R. arcuata individuals was observed in the Rio de la Plata estuary. In summer, this species apparently moves...

The present study was conducted to clarify the difference in the color of the cytoplasm in immature follicular oocytes from prepubertal and adult minke whales. The four lipid contents (triglyceride,total cholesterol phospholipids and non-esterified fatty acids) in vitrified immature oocytes from prepubertal and adult minke whales,and also in fresh and vitrified immature porcine oocytes,were measured. The lipid contents in vitrified-warmed minke whale oocytes were similarly high compared with those in vitrified-warmedp orcine oocytes. In particular,the total cholesterol and phospholipid contents in the vitrified immature oocytes from prepubertal and adult minke whales were significantly( P<0.05) higher than those from prepubertal pigs. Furthermore,the...

Different progestagens sources do not affect the follicular population and the morphological quality of oocytes during ovarian stimulation in Santa Inês ewes. Repositório Alice
BRAGANÇA, G. M.; SOUZA-FABJAN, J. M. G.; BATISTA, R. I. T. P.; RIBEIRO, L. S.; BRAIR, V. L.; CÔRTES, L. R.; SOUZA, C. V.; TRAIRA, A. R.; FONSECA, J. F. da; MENCHACA, A.; BRANDÃO, F. Z..
In attempt to develop a hormonal protocol more suitable to produce good quality oocytes for use in biotechnologies, an earlier study demonstrated that FSH applied in multiple decreasing doses produced better quality oocytes. However, different progestagens implants used during ovarian stimulation have not yet been tested. The aim of this study was to investigate the effect of different progestagens during ovarian stimulation on follicular population and oocyte morphological quality in Santa Inês ewes. In conclusion, the source of progestagens used during the ovarian stimulation protocol does not affect the follicular population, nor the oocyte quality. Exogenous progestagens may not be necessary when postsynchronization ovulation is confirmed by...

Donnees cytologiques, electrophysiologiques et biochimiques relatives au phenomene de fecondation chez le homard (Homarus gammarus ). Implication du processus d'activation sur le mecanisme d'attache des oeufs pondus ArchiMer
Goudeau, M; Lachaise, F; Kubisz, P; Goudeau, H.
Electrophysiological measurements and related cytological controls were done on immature and submature oocytes of Homarus gammarus . By chromatography (HPLC) and radio-immunoassays (RIA) it was established that submature oocytes displayed different ecdysteroids. Furthermore, the structure of the stalk (funiculus) for the laid eggs attachment was analyzed. it consisted of the two superimposed vitelline envelopes which were likely modified by the cortical reaction exudate during the fertilization process. In addition, the successive secretory phases, regarding to the embryonic envelopes were evidenced. Finally, the ecdysteroid titers of embryonic stages were measured.

Efeitos da redução ou substituição do soro fetal bovino por outros compostos na maturação in vitro de oócitos bovinos. Repositório Alice
DEL COLLADO, M.; SARAIVA, N. Z.; LOPES, F. L.; CRUZ, M. H.; GASPAR, R. C.; OLIVEIRA, C. S.; PERECIN, F.; GARCIA, J. M..
A utilização do soro fetal bovino (SFB), embora bastante disseminada na produção in vitro (PIV) de embriões bovinos, apresenta limitações por ser um meio indefinido e por causar efeitos que prejudicam a qualidade desses embriões. Por esse motivo, nos últimos anos, grande parte das pesquisas relacionadas à PIV está voltada para a substituição do SFB por outros compostos nos meios de cultura. No presente estudo, foram utilizados como compostos protéicos a albumina sérica bovina livre de ácidos graxos (BSA-FAF) e um produto comercial denominado fluido embriônico (FE) de maneira isolada ou em diferentes combinações e concentrações, com objetivo de substituir ou diminuir a concentração do SFB durante a maturação in vitro (MIV). Para isso, oócitos bovinos foram...

Effect of two ram sperm capacitating media on acrosome reaction and zona-free hamster oocyte penetration test Braz. J. Vet. Res. Anim. Sci.
FERRARI,Silvia; BARNABE,Valquíria Hyppolito; ZÜGE,Roberta Mara; ZOGNO,Maria Amélia.
An in vitro zona-free hamster oocyte penetration test was utilized in 24 trials in order to evaluate the capacitation media used for ram sperm. A pool of fresh semen was collected from three crossed breed rams. Two semen drops were washed by centrifugation and incubated in high ionic strength treatment (HIS) or in a defined medium with HEPES, on heat ewe serum and heparin. After the incubation to promote capacitation, simplified triple-stain technique was used to evaluate the spontaneous acrosome reaction of the capacitated sperm. Superovulation in 96 golden hamsters was induced by PMSG and hCG. The oocytes were treated with hyaluronidase and trypsin to remove, respectively, the cumulus cells and the zona pellucida. Oocytes and capacitated sperm were...

Molecular Characterization, Electrophysiological and Contraceptive Effect of Chilean Latrodectus Venom International Journal of Morphology
Navarrete Gómez,Patricia; Ormeño,David; Miranda,Antonio; Sánchez Gutiérrez,Raúl; Romero Mejía,Fernando; Parodi Rivera,Jorge.
Since the 1970s, There have been studies of the venom of Latrodectus sp. spiders, in particular the latrotoxin (LTX) of Latrodectus mactans. Many of the studies were aimed at understanding the action of the venom on the muscular system. Now accepted that LTX is able to generate a calcium-permeable membrane pore and modulate the release of synaptic vesicles that activate a receptor and induce cellular changes. Interestingly, when work began with venom obtained from the Latrodectus sp present in Chile, it generated clinical indications similar to the bite of this spider in another country, with some differences in intensity. The purpose of the first studies was to understand the systemic mechanisms of this venom, and other active compounds were studied for...

Ovarian histology and fecundity in the evaluation of the reproduction of the invasive species Serrasalmus marginatus (Characidae) on a neotropical floodplain Biological Sciences
Melo, Gabriele Sauthier Romano de; Santana, Herick Soares de; Tos, Claudenice Dei.
 The construction of the Itaipu Hydroelectric Power Plant in 1982 led to the formation of a reservoir, which, in turn, leveled the waters of the Paraná River by flooding the geographic barrier Salto de Sete Quedas. This allowed the piranha Serrasalmus marginatus to invade and colonize the upper Paraná River. This study aimed to: i) confirm, through light microscopy, the reproductive phases of S. marginatus females; ii) estimate fecundity and iii) evaluate the reproduction areas of the population. A total of 764 females were collected from nine sampling sites on the upper Paraná River floodplain. Microscopic analysis of the ovaries showed the following phases: early developing subphase, developing phase, spawning capable phase, actively spawning subphase,...

Relations entre le contenu lipidique des ovocytes de Pecten maximus (Mollusque, bivalve) et les performances des larves en élevage ArchiMer
Le Pennec, Marcel; Gueguen,.
The lipid content of spawned oocytes of Pecten maximus was studied by image analysis of semi -thin histological sections and a lipid index was defined. The female gametes were obtained by thermic stimulations of mature adults scallops from different populations after out of season conditioning or sampled in situ during the spawning season. After fertilization, the larval development was followed. The results reveal a large variability in lipid content of normal oocytes. The lipid content can be regarded as homogeneous inside a spawning but the heterogeneity is greater for wild scallops than for conditioned ones. A strong relationship appears between the lipid index and the hatching success, and the number of abnormal larvae after two days rearing. But no...

Reproduction and growth of the deep-sea brittlestar ophiura-ljungmani (lyman) ArchiMer
Tyler, Pa; Gage, Jd.
Reproductive biology and population dynamics of Ophiura Ijungmani were studied by measuring disk diameters and by examining oocyte size-frequencies and fecundity from a sequential seasonal series of large samples from a 2900 m deep Permanent Station in the Rockall Trough (Northeast Atlantic). Egg size (max. 90 !lm) and fecundity (up to 57000 eggs per individual) suggests indirect planktotrophic development, while a clear annual cycle in gametogenesis, with probably synchronous spawning in JanuaryFebruary, confirms a marked seasonality that is also seen as an annual, summertime set of postlarvae on to the bottom. Analysis of size structure of the population indicates annually discrete year classes with a maximum longevitv of around 10 years. lndividuals...

Structural and Ultrastructural Aspects of Folliculogenesis in Didelphis albiventris, the South-American Opossum International Journal of Morphology
Cesario,Maria Dalva; Matheus,Selma M. Michelin.
The ovarian histology, the structural and the ultrastructural characteristics of the folliculogenesis in Didelphis albiventris were described in detail. Recent studies suggest that methatherian mammals have unusual reproductive cycle but there are few informations regarding the marsupials reproductive life. Despite of the opossum folliculogenesis pattern resembles methatherian and eutherian pattern in many aspects, the analysis shows some peculiar features of the oocyte structure and ultrastructure that make available new data on the reproductive biology of marsupials.

Temperature and seston quantity and quality effects on field reproduction of farmed oysters, Crassostrea gigas, in Bourgneuf Bay, France ArchiMer
Dutertre, Mickael; Beninger, Peter G.; Barille, Laurent; Papin, Mathias; Rosa, Philippe; Barille, Anne-laure; Haure, Joel.
The proliferation of the voluntarily-introduced cupped oyster, Crassostrea gigas, has attained the proportions of species invasion in many intertidal habitats in Europe, presumably resulting from successful reproduction of farmed individuals. It is thus imperative to better understand the reproductive characteristics of farmed oysters, since they are directly under human control. We quantified the dry tissue mass (DTM), gametosomatic index (GSI), and reproductive cycle of farmed oysters at two sites in Bourgneuf Bay, France, in relation to environmental parameters using continuously-recording probes in 2005 and 2006. The GSI was developed for this study, based on the actual area occupied by gametes, rather than the area of the gonad previously used for...
