O camarão-sete-barbas Xiphopenaeus kroyeri está entre as espécies de crustáceos mais importantes do litoral brasileiro, com destaque social, econômico, ambiental e cultural. Além disso, destaca-se a ampla distribuição geográfica no litoral Atlântico Ocidental (Rio Grande de Sul - BR até a Carolina do Norte - EUA). Também evidencia-se o aumento da captura, com consequente diminuição dos estoques naturais. A falta de conhecimento sobre a biologia das espécies, principalmente aquelas visadas pelas frotas pesqueiras, diminui a eficiência de aplicações de medidas para proteção dos estoques naturais. O conhecimento sobre a dinâmica reprodutiva de uma espécie pode ser considerado importante e eficaz para controlar uma população explorada. Com relação aos crustáceos, o ciclo reprodutivo apresenta ovários em diferentes estágios de maturação e a determinação destes estágios envolve as atividades inerentes ao ovário e ao hepatopâncreas. Estes dois órgãos trabalham de forma sincronizada durante a vitelogênese. Assim, o objetivo deste estudo foi reavaliar alguns pontos referente a dinâmica celular em fêmeas de Xiphopenaeus kroyeri nos diferentes estágios de maturação ovariana. A classificação macroscópica e microscópica da maturação ovariana e o perfil celular dos túbulos hepatopancreáticos foram estudados através de análises histológicas e histoquímicas; a localização da síntese de vitelogenina no ovário e hepatopâncreas foi estudada através da imuno-histoquímica; e os índices gonadossomático (IGS) e hepatossomático (IHS) foram comparados.

The shrimp Xiphopenaeus kroyeri is among the most important shellfish species off the Brazilian coast, with several highlights such as social, economic, environmental and cultural. In addition, we highlight the wide geographic distribution in the western Atlantic coast (Rio Grande do Sul - BR to North Carolina - USA) and also the increase in artisanal fisheries with consequent reduction of the natural stocks. The lack of knowledge about the biology of the species, especially those targeted by fishing fleets, decreases the efficiency of strategies for protection of natural stocks. Knowledge about reproductive dynamics of a species is considered important and effective to control an exploited population. Regarding the crustaceans, the reproductive cycle is composed of ovaries at different stages of maturation, and the determination of these stages involves activities related to the ovary and hepatopancreas. These two organs work synchronously during vitellogenesis. The objectives of this study were to reevaluate some points in females in different stages of ovarian maturation. Macroscopic and microscopic classification of ovarian maturation and the cellular profile of hepatopancreatic tubules were studied by histological and histochemical analyzes; the location of vitellogenin synthesis in ovary and hepatopancreas was studied by immunohistochemistry and the gonadosomatic (GSI) and hepatosomatic (IHS) indices were compared. Thus, X. kroyeri ovary features six maturity stages: immature, pre-mature, early maturation, advanced maturation, mature and spawned.

It is known that in penaeid shrimp the vitellogenin is synthesized into the ovary and hepatopancreas, but the relative contribution of these two tissues in the synthesis of vitellogenin remains uncertain. This process differs according to the species and vitellogenesis stage or molt. Thus the present study examined the location of vitellogenin production by immunohistochemical techniques, as well as the quantification of its mRNA by Real Time PCR in female Artemesia longinaris at different stages of ovarian maturation (immature - RU, maturing EM and mature - MA). The shrimp species investigated presented a very high economic value. The study of the mechanisms of reproduction can generate data for future projects of commercial scale production contributing with the preservation of wild stocks. The molecular analyzes have confirmed the vitellogenin synthesis in the ovary and hepatopancreas of A. longinaris females during ovarian maturation. the relative expression level of vitellogenin transcripts in the ovary and the hepatopancreas during ovarian maturation show that the dynamics of vitellogenin synthesis is inversely proportional. By immunohistochemistry, it was located the endogenous synthesis of vitellogenin in follicular cells, in pre-vitellogenic oocytes and oocytes in early vitellogenesis. And the synthesis exogenous of vitellogenin was localized in cells R of hepatopancreaticos tubules. Also, given the great contribution of hepatopancreas reproductive cycle and other physiological functions of the animal, we analyzed the cellular profile of the hepatopancreatic tubule at stages of ovarian maturation. This organ has a cellular behavior that adapts to the reproductive cycle in females, in other words, the cellular cycle of hepatopancreas beyond to follow a digestive cycle is adapted to the reproductive cycle

Full textPresenta fecundació interna i a l'interior de l'ovari conté estructures d'emmagatzematge que permeten emmagatzemar l'esperma durant períodes de temps considerablement llargs. Les cèl·lules sexuals masculines es mantenen viables gràcies a diverses substàncies nutritives que obtenen de la bossa citoplasmàtica i de l'epiteli criptal que delimita les estructures d'emmagatzematge. Aquest epiteli és també responsable de la seva protecció. Un cop els ous han assolit la maduresa, els espermatozoides són alliberats al lumen ovàric i es dóna la fertilització. És una espècie zigòpara: allibera òvuls fecundats que han estat retinguts al tracte reproductiu femení durant un curt període de temps i, per tant, els embrions són alliberats en estadis molt primerencs de desenvolupament. Així, el penegal presenta una estratègia reproductiva evidentment eficaç.
The bluemouth, Helicolenus dactylopterus dactylopterus (Pisces: Scorpaeniformes), is a species that inhabits the seabed at depths between 200 and 1000 m and shows a clear size-dependent bathymetric distribution.
It has internal fertilization and, inside the ovary, there are storage structures that allow it to store sperm for considerably long periods of time. These male sexual cells remain viable thanks to several nutritious substances they obtain from the cytoplasmic bag and from the cryptal epithelium that delimits the storage structures. This epithelium is also responsible for their protection. Once the eggs have reached maturity, the spermatozoa are freed in the ovarian lumen and fertilization occurs. This species is zygoparous: liberation of fertilized ova, which have been retained in the female reproductive tract during a short period of time and, therefore, the embryos are freed in very early stages of development. Thus, the bluemouth exhibits an obviously effective reproductive strategy.

O objetivo deste estudo foi avaliar métodos alternativos de muda forçada e compará-los ao método convencional (jejum) e ao grupo controle. Para isso realizou-se o experimento nas instalações do Setor de Avicultura da Faculdade de Medicina Veterinária e Zootecnia UNESP Botucatu SP. Foram utilizadas 480 aves da linhagem Isa Brown, com 80 semanas de idade, distribuídas em 6 tratamentos contendo 10 repetições de 8 aves por gaiola. O período experimental compreendeu período de descanso forçado com duração de 28 dias onde se avaliou os parâmetros de peso corporal, ovário, oviduto, fígado, gordura abdominal, teores de cálcio e fósforo contido na cinza do metatarso e desempenho produtivo das aves. Os tratamentos utilizados foram dietas de produção com restrição de componentes: T1 cálcio e fósforo, T2 cálcio, fósforo e sódio, T3 cálcio, fósforo, sódio e aminoácidos (metionina e lisina), T4 fornecimento de milho moído, T5 muda convencional através de jejum de 14 dias seguido de ração de produção até 28 dias e T6 grupo controle que recebeu ração de produção. Durante a muda todos os tratamentos receberam água e retirou-se o programa de luz artificial. O T5 promoveu maior perda de peso corporal que os demais tratamentos. Tais perdas repercutiram em incremento no consumo voluntário de ração de produção nas primeiras semanas após o período de jejum. O jejum permitiu uma completa regressão do trato reprodutivo das aves, que cessaram a postura no período. Os tratamentos com restrição de nutrientes e de milho, promoveram redução do peso vivo, do aparelho reprodutivo e do consumo voluntário de ração, porém não cessaram a produção de ovos.
The objective of this study was to evaluate alternative forced molting systems and compare then to the traditional system (fasting) and to the control group. The trial was carried out at the Faculdade de Veterinária e Zootecnia (UNESP-Botucatu) Poultry Section. Four hundred and lighty 488 Isa Brown line hens, 80 weeks old, were assigned to 6 treatments with 10 replicates of 8 hens per cage. The experiment comprised, a 28 day resting period during which, we evaluated live weight, ovary, oviduct, liver, abdominal fat, calcium and phosphorus in tarsus ash and production traits. Treatments were production diets with nutrient or ingredient restriction: T1 calcium and phosphorus, T2 calcium, phosphorus and sodium, T3 - calcium, phosphorus, sodium and aminoacids (lysine and methionine), T4 ground corn feeding, T5 conventional forced molting: 14 days fasting followed by production ration feeding until 28 days, T6 control group fed production ration. During the molting period all hens had access to water and the light program was suspended. TheT5 promoted larger bady weight loss than the other treatments. Such losses resulted in an increment in the voluntary intake in the first weeks after the fasting period. Fasting allowed a complete regression of the reproductive tract of the birds and interrupted laying. The ingredient restriction treatments and ground corn feeding promoted reduction of body weight, of the reproductive tract and of the voluntary feed intake. They reduced, bit they didn't interrupt the egg laying.

Resumo: O objetivo desse estudo foi avaliar a histologia e morfometria de ovários de 17 gatas classificadas de acordo com as idades G1 (4-12 meses); G2 (1-6 anos) e G3 (> 6 anos). Após realização da ovariosalpingo-histerectomia os ovários foram fixados, processados rotineiramente para a inclusão em parafina e corados com Hematoxilina-eosina. Os parâmetros morfométricos analisados foram: diâmetro (μm), área (μm2) e perímetro (μm) dos folículos e respectivos oócitos de diferentes tipos de folículos. A relação entre o crescimento do folículo e do oócito foi analisada. Os procedimentos estatísticos utilizados foram ANOVA, sendo as médias comparadas pelo teste de Tukey e as medianas pelo teste de Kruskal-Wallis, seguido do teste de comparações múltiplas de Dunn (P< 0,05). Ao todo foram 1039 folículos analisados histologicamente e houve diferença significativa nos diâmetros, áreas e perímetros foliculares e oocitários de folículos primordiais e primários unilaminares. Observou-se padrão bifásico para o crescimento do folículo e do oócito. Conclui-se que as gatas jovens obtiveram maiores valores em folículos primários unilaminares em relação às idosas. Sugere-se que o "pool" de folículos pequenos remanescentes e seus respectivos oócitos diminuem com a idade e que na fase senil esses folículos são de baixa qualidade, quando comparados ao início da vida reprodutiva. Estudos com morfometria do ovário poderão auxiliar pesquisas de tecnologias reprodutivas assistidas, como por exemplo, a maturação in vitro (MIV), já que o tamanho e a qualidade dos folículos e oócitos podem afetar a MIV em felinos domésticos. Adicionalmente, esses estudos poderão auxiliar na preservação de felinos selvagens em extinção
Abstract: The aim of this study was to evaluate the histology and morphometry of ovaries of 17 cats classified according to ages G1 (4-12 months), G2 (1-6 years) and G3 (>6 years). After ovariosalpingohysterectomy the ovaries were fixed in paraformaldehyde 5% prior to embedding in paraffin and staining with haematoxylin-eosin. The morphometric parameters analyzed were: diameter (μm), area (μm2) and perimeter (μm) of follicles and oocytes from different follicles types. The relationship between the growth of the follicle and oocyte was analyzed. The statistical analysis were ANOVA and the means were compared by Tukey test and medians using the Kruskal-Wallis test followed by Dunn's multiple comparisons (P<0.05). A total of 1039 follicles were analyzed histologically and there were significant difference in follicular and oocyte diameter, area and perimeter of primordial and primary unilaminar follicles. It was observed a biphasic pattern for the growth of the follicle and oocyte. In conclusion, young queens had higher values in primary unilaminar follicles than older queens. It is suggested that the remaining pool of small follicles and their oocytes decreases with age and that follicles of older queens has low quality compared to the beginning of reproductive life. Ovarian morphology studies may assist in assisted reproductive technologies such as in vitro maturation (MIV), since it is known that the size and quality of follicles and oocytes may affect the MIV in domestic queens. Additionally, it may assist in the preservation of endangered wild felines

Full textEl presente trabajo quiere asentar las bases para estudiar la polaridad en el oocito en una especie filogenéticamente basal como la cucaracha Blattella germanica. Para ello, y basándonos en la información disponible sobre genes implicados en el establecimiento de la polaridad en Drosophila melanogaster, escogimos algunos genes clave. Hemos estudiado el factor de transcripción Capicua, que en B. germanica actúa como represor de la transcripción, y es imprescindible para la formación del eje dorso-ventral del huevo y del embrión. EGFR (epidermal growth factor receptor) que participa también en el establecimiento de la polaridad en el folículo ovárico. Estudiamos la función de la vía Notch, y como los componentes de esta vía afectan el correcto desarrollo del oocito. Además, tratando de establecer una relación entre Capicua y EGFR estudiamos la función de Pipe en el ovario y el embrión de B. germanica.

Full textThe effect of mutating the pro-apoptotic Bax molecule was studied at three distinct ages corresponding to the time when female germ cells are premeiotic, in meiotic prophase, and arrested in dictyotene. Although it appeared that more germ cells were retained in the Bax homozygous mutant compared to the wild-type and heterozygous mice at 18.5 dpc, by 24.5 dpc all of the mice possessed similar numbers of germ cells. These results indicate a role for Bax in germ cell death but also support the idea that an alternative pathway can compensate for the elimination of this molecule.

Resumo: Pouco se sabe sobre os eventos morfológicos que ocorrem durante o desenvolvimento pré-natal das gônadas nas raças zebuinas. O objetivo deste estudo foi descrever os eventos morfológicos relacionados ao desenvolvimento pré-natal da gônada, incluindo a sua formação, identificação de células germinativas primordiais, surgimento de oogônios, oócitos e folículos em embriões e fetos da raça Nelore. Oitenta e um embriões e fetos bovinos, com idade variando de 26 a 240 dias após fecundação, foram coletados em frigoríficos. A idade dos fetos foi estimada a partir de medidas tomadas no sentido crânio-caudal e aplicadas à fórmula proposta por Rexroad et. al. (1974). O sexo foi identificado a partir de observações macroscópicas e usando a técnica do PCR (Polymerase Chain Reaction) somente quando as diferenças sexuais morfológicas não foram evidentes. Para histologia, as gônadas foram fixadas em líquido de Bouin por 24 horas. Após processamento histológico, cortes de tecido de 5mm, foram corados com hematoxilina-eosina. Os resultados mostraram que a crista gonádica se formou a partir de 29 dias após fecundação. No 34º dia, células germinativas primordiais foram identificadas. As oogônias surgiram em grande quantidade entre 50 e 100 dias e seu número reduziu drasticamente, atingindo números finais aos 140 dias. Os folículos primordiais, folículos em crescimento e antrais apareceram em média aos 95, 140 e 180 dias, respectivamente. Oogônias e folículos primordiais, de forma diferente dos folículos em crescimento, apresentaram diferenças significativas no seu diâmetro nos vários períodos estudados. Folículos antrais mostraram diâmetro médio de 96,92 l 31,07mm aos 180 dias , chegando atingir médias de1331,43 l 567,43mm aos 240 dias... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: Little is known about morphological events occurring during the prenatal development of gonads in the Zebu breeds. The objective of this study was to describe the morphologic events related to the prenatal development of the gonad, including its formation, identification of primordial germinative cells, appearance of oogonia, oocytes and follicles in Nelore breed embryos and fetuses. Eighty-one bovine embryos and fetuses, with age range from 26 to 240 days following fecundation, were gathered in a local slaughter-house. The age of fetuses was estimated from measures taken in the cranium-caudal direction and applied to the formula proposed by Rexroad et. al. (1974). The sex was identified from macroscopic observations and using PCR (Polymerase Chain Reaction) technique only when the morphologic sexual differences were not evident. For histology, gonads were fixed into Bouin fluid for 24 hours. Then, 5mm-tissue cuts were stained with hematoxylin-eosin. The results showed that the gonadal ridge was developed from 29 days following fecundation. At the 34th day, primordial germ cells were identified. Oogonia arose in great quantity between 50 and 100 days and its number reduced dramatically, attaining final numbers at 140 days. The primordial follicles, growing follicles and antral follicles appeared on the average at 95, 140 and 180 days, respectively. Oogonia and primordial follicles, in a different way from growing follicles, presented significant differences in its diameter in the several periods studied. Antral follicles showed 96.92 l 31.07mm in diameter at 180 days, achieving means of 1331.43 l 567.43 mm at 240 days. The statistical analysis showed a positive and highly significant correlation (P< 0.01), between the oogonia diameter and its nucleus, as well as between the primordial and growing follicles with its oocytes and respective nuclei...

Full textThe objectives of this study were: 1) To determine the effect of oocyte retrieval techniques (slicing and aspiration) on the quality and quantity of cattle oocytes, 2) To evaluate the effect of different concentrations of hormones on the maturational rate of cattle oocytes selected by brilliant cresyl blue staining, 3) To evaluate fertilization rate and cleavage/embryonic development of oocytes with or without cumulus cells, and 4) To compare the effect of fresh and frozen thawed semen on the fertilization rate of cattle oocytes. In Experiment 1: oocytes were recovered from abattoir derived ovaries using slicing and aspiration. The recovered oocytes were exposed for 90 minutes to 26μM of brilliant cresyl blue (BCB) stain and classified according to the colour of their cytoplasm: BCB+ (oocytes with blue cytoplasm) and BCB- (unstained oocytes). There was no difference (P>0.05) in the quality of oocytes recovered using slicing (60.7 %) or aspiration (53.7 %) techniques. In experiment 2: The BCB selected and the non-selected immature oocytes were randomly allocated into medium 199 + 10 % fetal bovine serum (FBS) maturation media. The media was supplemented with three different concentrations of hormones as treatments (T). The T1 (0.5 μg/ml of follicle stimulating hormone (FSH), 5mg/ml of luteinizing hormone (LH) and 2 μg/ml of estradiol (E2) as the control group. Then, T2 (1 μg/ml of FSH, 6 mg/ml of LH and 2.5 μg/ml of E2) and T3 (1.5 μg/ml of FSH, 7 mg/ml of LH and 4.5 μg/ml of E2). Maturation rate of oocytes was determined by the protrusion of the first polar bodies 24 hours following in vitro maturation. Treatment 2 yielded higher (P<0.05) maturation rate for both BCB+ (65.6 %) and without BCB (60.3 %) oocytes with T1 giving lower (P<0.05) maturation rate for BCB+ (22 %) and without BCB (16 %) oocytes. However, BCB- oocytes had lower (P<0.05) polar body extrusion (3.03 %, 8.1 % and 2.2 %) for T1, T2 and T3, respectively. In Experiment 3: one group of the presumptive zygotes was denuded of cumulus cells and the other group was cultured with cumulus cells. The presumptive zygotes were in vitro cultured in SOF-BSA and changed to SOF-FBS after 48 hours. High fertilization/cleavage rate was observed in oocytes cultured with cumulus cells (29.0 %) compared to the denuded oocytes (20.0 %) for 2-4 cells stage. Day 7 blastocysts were more (P<0.05) on oocytes cultured with cumulus cells (32 %) compared to denuded oocytes (13 %). In experiment 4: The matured oocytes were fertilized using fresh and frozen thawed semen. The oocytes fertilized with frozen thawed semen obtained a better number of 2-4 cell cleavage (23 %) when compared to fresh semen (19 %). Oocytes that were fertilized with frozen thawed semen also obtained higher morula (13 %) and blastocyst (8 %) compared to fresh semen with morula (3.4 %) and blastocyst (2 %). In conclusion, immature oocytes that were exposed to BCB+ and cultured in M199 supplemented with 10 % FBS, 0.5 μg/ml of FSH, 5 mg/ml of LH and 2 μg/ml of E2 had a higher (P<0.05) number of matured oocytes (extrusion of first polar body) compared to those that were not exposed to BCB (no BCB). Oocytes that were cultured with cumulus cells yielded a higher (P<0.05) number of cleaved embryos compared to the denuded oocytes. Slicing yielded a higher (P<0.05) number of oocytes, however the quality of oocytes recovered was similar compared to those recovered by the aspiration technique (P>0.05). Oocytes fertilized with frozen thawed semen yielded higher (P<0.05) number of 2-4 cell, morula and blastocyst when compared with oocytes that were fertilized using fresh semen.

Full textIntrodução: O câncer de ovário (CO) é a maior causa de morte por neoplasia ginecológica nos países desenvolvidos. Atualmente, um modelo dualístico de classificação foi proposto, sendo os tumores tipo I de baixo grau, indolentes e com mutações estáveis. Os tumores tipo II são de alto grau e mais agressivos. Além disso, na tentativa de se entender o processo de carcinogênese, vários biomarcadores têm sido estudados como as micropartículas (MPs), as citocinas e as quimiocinas. O objetivo desse estudo é a avaliação de fatores solúveis da resposta inflamatória (MPs, citocinas e quimiocinas) em mulheres com CO e compará-los com os níveis encontrados em mulheres sem malignidade e com parâmetros clínicos. Métodos: Avaliaram-se 26 mulheres com CO e 16 mulheres sem evidência de neoplasia maligna (grupo controle). Foram coletadas amostras de plasma e tecido tumoral. A avaliação dos fatores inflamatórios foi realizada por meio da dosagem de citocinas (IL-1- β, IL-2, IL-6, IL-10, IL-12, IL-17A, TNF e IFN-gama, e quimiocinas (CXCL8, CXCL-9, CXCL 10, CCL 2, CCL5) e das micropartículas (neutrófilos, leucócitos, monócitos, eritrócitos, endotélio, plaquetas e linfócitos) por citometria de fluxo/CBA (Cytometric Bead Array). As diferenças entre os grupos foram avaliadas pelos testes Kruskal- Walis ou Mann-Whitney e a sobrevida por Cox Regression. As diferenças com valor de p<0,05 foram consideradas significativas.Resultados: Não houve diferença entre os grupos em relação à idade, paridade e menopausa. No grupo de mulheres com CO, 10 (38,5%) tinham estadio I/II e 16 (61,5%) tinham estadio III/IV. Em relação ao tipo tumoral, segundo a nova classificação, 8 (30.8%) eram tipo I e 18 foram tipo II (69.2%). Citorredução ótima foi obtida em 15 (57.7%) mulheres com CO. Os valores de CA 125 foram significativamente diferentes entre os grupos. Não houve óbito em mulheres com tumores ...
Introduction : Ovarian cancer ( OC) is the leading cause of death from gynecological cancer in developed countries . Currently , a dualistic classification model was proposed .Type I tumors are low-grade , indolent and have stable mutations . Type II tumors are high grade and more aggressive . Moreover, in an attempt to understand the process of carcinogenesis , several biomarkers have been studied as microparticles (MPs ) , cytokines and chemokines. The purpose of the study was to evaluate the levels of circulating soluble biomarkers-microparticles, cytokines and chemokines- to characterize the pro-inflammatory/modulatory immune response in women with OC. The correlation between the biomarker levels and the clinico-pathological parameters were also analyzed. Methods : We evaluated 26 women with OC and 16 women without evidence of malignancy ( control group ) . Plasma samples and tumor tissue were collected . The assessment of inflammatory markers was performed by measurement of cytokine (IL -1- β , IL-2 , IL-6 , IL-10 , IL-12 , IL -17A , TNF and IFN –gamma), chemokines ( CXCL8 , CXCL -9 , CXCL 10 , CCL 2 , CCL5 ) and microparticles (neutrophils , leukocytes, monocytes, erythrocytes, endothelium , platelets and lymphocytes) by flow cytometry / CBA ( cytometric Bead Array) . Differences among groups were evaluated by Kruskal - Wallis or Mann - Whitney and survival by Cox Regression . Differences with p < 0.05 were considered significant. Results: There was no difference between groups regarding age , parity and menopause. In the group of women with OC , 10 ( 38.5 % ) were stage I / II and 16 ( 61.5 % ) were stage III / IV . Concerning tumor type , according to the new classification , 8 (30.8 % ) were type I and 18 ( 69.2 % ) were type II . Optimal cytoreduction was achieved in 15 ( 57.7 % ) women with OC . CA 125 values were significantly different between groups . There were no deaths in women with type I tumors. Stratifying by ...
