Concentrations of 12 major and trace minerals and cholesterol in commercial goat fluid milk, evaporated, powdered, yogurt, and cheese products manufactured in the US were evaluated for compositional differences. Minerals were determined by an Inductively Coupled Argon Plasma Emission Spectroscopy (ICAP), while cholesterol was analyzed using colorimetric and gas chromatographic (GC) methods. Mea...

Age-associated decline in oocyte quality is common in mammals. Oocytes take a long time to reach their full-grown size in large animals, and maternal physical conditions profoundly affect follicle development. Aging affects the oocyte itself as well as the surrounding environment, such as granulosa cells and follicular fluid. This review discusses age-associated changes that occur in granulosa ...

The aim of this study was to biochemically characterize ovine follicular fluid and to relate possible changes in composition to follicular size. Ovaries were collected from adult and cycling non-pregnant slaughtered sheep (Ovis aries) during breeding season. A total of 104 pairs of ovaries were investigated and these data were then compared. Follicular fluid was aspirated from small (< 2 mm), m...

background: fat-rich diet may alter oocyte development and maturation and embryonic development by inducing oxidative stress (os) in follicular environment. objective: to investigate the relationship between fat intake and oxidative stress with oocyte competence and embryo quality. materials and methods: in observational study follicular fluid was collected from 236 women undergoing assisted re...

Topographic and ultrastructural changes in the infundibular segment of goat (Capra hircus) oviduct has been studied during the follicular and luteal phases of the oestrous cycle. Histologically, the mucosal epithelium of the infundibulum revealed characteristic pattern of changes in the number, height, branching of the mucosal folds and relative frequency of ciliated and secretary cells during ...

OBJECTIVES The aim of the present study was to measure serum and follicular fluid 25-OH vitamin D and glucose levels in women who underwent IVF-ET treatment and to further investigate whether the circulating 25-OH vitamin D and glucose levels correlate with IVF success. METHODS This prospective observational study included 101 consecutive women who underwent 101 IVF-ICSI ovarian stimulation c...

G-CSF in individual follicular fluids correlates with the potential of the corresponding embryo to result in a live birth after transfer in IVF. To evaluate the requirements for routine follicular fluid G-CSF quantification, we compared follicular fluid G-CSF measurements made with two multiplexed microbead assays purchased from Bio-Rad Laboratories and R&D Systems, and a commercial G-CSF ELISA...

BACKGROUND In order to investigate whether gonadotrophin-releasing hormone (GnRH) antagonists exert a significant effect on steroid secretion in vivo compared with GnRH agonists, concentrations of sex steroid hormones (oestradiol, progesterone and testosterone) were studied in follicular fluid from women undergoing ovarian stimulation and treated with either GnRH agonist or antagonist. In addit...

Inhibin activity was measured by bioassay in follicular fluid of 99 individual ovine follicles ranging from 1 . 4 to 6 . 8 mm diameter (used to calculate volume) and in various stages of atresia. Treatment of samples before assay with charcoal concentrations of greater than 1 mg/ml resulted in significant loss of inhibin activity. The inhibin content of follicular fluid from individual follicle...

BACKGROUND Endometriosis is associated with pituitary-ovarian axis dysfunction. The study of the follicular fluid in patients with endometriosis is important to elucidate the pathophysiological mechanism of this disease. The objective of this present paper was to analyse the dosages of insulin-like growth factor-1 (IGF-1) and IGF binding protein-1 and 3 (IGFBP-1 and IGFBP-3) in the follicular f...
