1. Antral follicle count, productive and reproductive parameters in Bos indicus and Bos indicus-taurus prepubertal heifers with early puberty induction
RESUMO Novilhas pré-púberes Nelore (G-N=15) e mestiças Nelore x Aberdeen Angus (G-NA=15) foram utilizadas neste estudo. CFA, peso vivo, escore de condição corporal (ECC), diâmetros do ovário e folículo dominante (FD) foram determinados em cada animal. A indução da puberdade foi realizada pela inserção de um dispositivo de progesterona de quarto u

2. Somatic embryogenesis in the commercial papaya hybrid UENF/Caliman 01 relying on plantlet production from sexed adult hermaphrodite donor plants
Abstract: Somatic embryogenesis from explants from hermaphrodite papaya mother plants is an alternative for the production of true-to-type plants without the need for sexing. This study aimed to analyze hormonal and osmotic inducers in different somatic embryogenesis stages in the commercial hermaphrodite hybrid papaya UENF/Caliman 01. Leaf disks from in vit

3. Induction of puberty and synchronization of estrus in gilts with eCG and GnRH
ABSTRACT In this study, we investigated the effects of eCG and GnRH on the induction of puberty in prepubertal gilts and evaluated the pregnancy rate and litter size in these females. Thirty 140-day-old gilts with an average weight of 80 kg were randomly divided into two treatments: hormonal treatment (n = 15): 1000 IU of eCG and 50 μg of GnRH; and control

4. Short, medium or long-term hormonal treatments for induction of synchronized estrus and ovulation in Saanen goats during the nonbreeding season
The objective of this study was to compare the effect of hormonal treatment duration through the use of intravaginal sponges impregnated with 60 mg MAP for 6 (G6; n = 10), 9 (G9; n = 10) or 12 (G12; n = 10) days. All nulliparous (n = 15) and lactating (n = 15) Saanen goats received 37.5 µg d-cloprostenol and 200 IU eCG 24 hours before sponge removal during

5. Performance and carcass traits in the diallel crossing of pacu and tambaqui
With the purpose of evaluating the changes and the degree of heterosis on performance and carcass traits of fish from the diallel crossing between Pacu and Tambaqui, four genetic groups were generated through hormonal induction: pacu, tambaqui, tambacu and paqui. For 196 days, 400 juveniles of each genetic group were stocked in a pond divided into four parts

6. Influência da hiperglicemia e do estresse oxidativo na cinética de proliferação e morte celular no epitélio acinar da próstata de ratos diabéticos / The influence of hyperglycemia and oxidative stress in proliferation and cell death kinetics in prostate acinar epithelium of diabetic rats
The diabetes damages in prostate morphophysiology are well known and are triggered by insulin lack, low androgen levels and hyperglycemia. Previous researches showed an individual variation in morphological prostate response against this disease. In order to clarify the factors responsible for this variation, we examined the correlation between histological

7. Timed hormonal treatments in induction and synchronization of Saanen goats estrus during nonbreeding season.
With the aim to evaluate reproductive performance of Saanen goats among different timed hormonal protocols during nonbreeding season, 30 females had the estrus cycles induced and synchronized by insertion of an intravaginal sponge impregnated with 60mg Medroxyprogesterone Acetate. All goats received 200 IU eCG and 37.5 ?g PGF2? analog 24 hours prior to spong

8. Análise do óxido nítrico produzido durante a indução da organogênese adventícia em bases foliares de abacaxizeiro / Analysis of nitric oxide produced during the induction of the adventitious organogenesis in basal leaves of pineapple
O óxido nítrico (NO) tem se mostrado um sinalizador presente em muitas fases do desenvolvimento vegetal e elemento essencial nas respostas aos estresses bióticos e abióticos em plantas. Entretanto, poucos estudos correlacionam esse radical à organogênese vegetal. Folhas de Ananas comosus (Bromeliaceae) podem ser consideradas um modelo interessante para

9. IN VITRO GERMINATION, ESTABLISHMENT, REGENERATION AND CALLI INDUCTION IN EXPLANTS OF AÇOITA-CAVALO (Luehea divaricata Mart. &Zucc.) / GERMINAÇÃO, ESTABELECIMENTO, REGENERAÇÃO E CALOGÊNESE IN VITRO EM EXPLANTES DE AÇOITA-CAVALO (Luehea divaricata Mart. &Zucc.)
O avanço da biotecnologia na área florestal tem favorecido as técnicas de propagação in vitro de espécies que apresentam dificuldades na reprodução via sementes. Luehea divaricata Mart. &Zucc (açoita-cavalo), integrante da família Malvaceae, é uma espécie florestal que sofreu, nas últimas décadas, grande redução das áreas ocupadas por popula

10. The effects of diazepam on the elevated T-maze are dependent on the estrous cycle of rats
In order to determine the modulation of anxiolytic and panicolytic-like effects of diazepam by the hormonal cycle of female rats, male and female rats - the latter divided per estrous cycle phase (estrus, diestrus, metaestrus and proestrus) - were tested in the elevated T-maze, a behavioral model of panic and anxiety. Diazepam (0.5, 1.0 and 2.0 mg/kg) or sal

11. Efeito de um protocolo hormonal a base de progestágeno e eCG sobre o desempenho reprodutivo de ovelhas mestiças durante o período de contraestação reprodutiva
O objetivo deste trabalho foi avaliar o desempenho reprodutivo de ovelhas mestiças lanadas e deslanadas submetidas a um protocolo hormonal a base de progestágeno, durante a contraestação reprodutiva. No primeiro experimento, 48 ovelhas mestiças, sem raça definida, com escore de condição corporal médio 3,2 ± 0,5 e peso vivo médio 41 ± 2 kg foram d

12. Influência do diâmetro do folículo dominante sobre as taxas de ovulação e gestação de vacas da raça Gir em anestro pós-parto submetidas a protocolo hormonal com progesterona associada a estradiol
This study was done to evaluate the influence of the dominant follicle diameter at beginning of progesterone and estradiol protocol, on ovulation and pregnancy rates of 100 postpartum anestrous Gyr cows. Cows were maintained on pasture and under twice daily suckling, average 66.1 24.5 days postpartum. Animals were allocated into four treatments with 25 anima
