1. Effect of eCG on the follicular dynamics and vascularization of crossbred cows with different circulating progesterone concentrations during synchronization of ovulation in an FTAI protocol
RESUMO: Objetivou-se neste estudo avaliar o efeito do tratamento com gonadotrofina coriônica equina (eCG) sobre a dinâmica e função folicular em fêmeas mestiças com diferentes concentrações circulantes de P4 durante a sincronização da ovulação em um protocolo de IATF. Para tanto, foram utilizadas 30 fêmeas mestiças e submetidas a um protocolo d

2. Milk production in Saanen goats treated with repeated low doses of intermediate-release insulin during early lactation
RESUMO: O objetivo do estudo foi avaliar o efeito da administração de insulina sobre a resposta produtiva de cabras Saanen durante a lactação inicial. Dez de vinte fêmeas adultas foram sujeitas à administração subcutânea de repetidas e baixas doses de insulina de liberação intermediária aos 2, 9 e 14 dias pós-parto. A produção de leite foi me

3. Standard Body Weight and Serum Estradiol and Progesterone Concentrations in Response to Total Lysine Content in Female Broiler Breeders from 14 to 42 Days after Hatch
ABSTRACT This study was conducted to determine the total lysine requirement for female broiler breeders from days 14 to 42. Two-hundred and ten female broiler breeders were used in a completely randomized design with 6 replicates per treatment and 5 chicks per pen under restricted feeding. The contents of total lysine used in this experiment were 0.68, 0.72,

4. Sex differences on solid organ histological characteristics after brain death1
PURPOSE: To investigate gender differences in the evolution of the inflammatory process in rats subjected to brain death (BD). METHODS: Adult Wistar rats were divided into three groups: female; ovariectomized female; and male rats. BD was induced using intracranial balloon inflation and confirmed by maximal pupil dilatation, apnea, absence of reflex, and

5. Activity of Corylus avellana seed oil in letrozole-induced polycystic ovary syndrome model in rats
Abstract The aim of the present study was to assess the activity of the hazelnut oil in the treatment of polycystic ovary syndrome in rats. Serum follicle-stimulating hormone, luteinizing hormone, estradiol, progesterone, testosterone, serum lipid parameters, leptin and glucose levels were evaluated. Moreover, antioxidant activity was tested using superoxide

6. Use of Ursodeoxycholic Acid on Post-menopausal Obesity, Hepatic steatosis and Plasma Profile as an Alternative Treatment for Hormone Replacement Therapy
ABSTRACT The aim of this study was to evaluate the efficacy of the ursodeoxycholic acid (UDCA) as an alternative treatment for menopause pathologies. For this, female Swiss-CD-1 mice were ovariectomized (OVX); SHAM operated mice served as controls. Ten weeks after operation, each group of mice was treated during four weeks with either UDCA, or 17(-estradiol+

7. 17,20β-P and cortisol are the main in vitro metabolites of 17-hydroxy-progesterone produced by spermiating testes of Micropogonias furnieri (Desmarest, 1823) (Perciformes: Sciaenidae)
The aim was to investigate the major C21 steroids produced by spermiating white croaker Micropogonias furnieri (Sciaenidae) in order to establish the potential mediator of gamete maturation in males of this species. The testes steroid production at the spawning season was identified incubating the 3H-17-hydroxy-4-pregnene-3,20-dione precursor through thin la

8. Frequency of estrus in Santa Inês, Texel and Ile de France ewes in the northwest of Paraná State, Brazil
The incidence of estrus in nulliparous Santa Inês (n = 16), Texel (n = 16) and Ile de France (n = 15) ewes fed two levels of crude protein (CP, 12 or 16%) was monitored from July 2005 to December 2006, and seasonality in the Santa Inês breed in the south of Brazil was characterized. The solar radiation data were recorded daily, and samples of blood were co

9. Roles of estrogen and progesterone in modulating renal nerve function in the rat kidney
The maintenance of extracellular Na+ and Cl- concentrations in mammals depends, at least in part, on renal function. It has been shown that neural and endocrine mechanisms regulate extracellular fluid volume and transport of electrolytes along nephrons. Studies of sex hormones and renal nerves suggested that sex hormones modulate renal function, although thi

10. Follicular dynamics and production of oocytes in young Nellore heifers with energetic supplementation
To verify the effects of energy supplementation and fat on follicular dynamics, metabolic profile and the production of oocytes, 15 young heifers (Bos taurus indicus) with an average age of 14 months and with an initial weight of 256.35 kg were assigned to two treatments according to weight and follicular population as evaluated by ultrasonography: in T1 (1.

11. Plasma urea nitrogen and progesterone concentrations and follicular dynamics in ewes fed proteins of different degradability
The effects of overfeeding with protein of different degradability on body condition, plasma urea nitrogen and progesterone concentrations, ovulation number and follicular dynamics were assessed in Santa Ines ewes. Twelve ewes were assigned to a randomized block design according to body weight and received overfeeding with soybean meal or with corn gluten me

12. Estrous cycle and stress: influence of progesterone on the female brain
The female brain operates in a constantly changing chemical milieu caused by cyclical changes in gonadal hormones during the estrous cycle (menstrual cycle in women). Such hormones are highly lipophilic and pass readily from the plasma to the brain where they can influence neuronal function. It is becoming clear that the rapid reduction in peripheral circula
