The aim of this study was to identify differentially expressed proteins in the follicular fluid of Tianzhu white yak during diestrus. Follicles obtained from female yak were divided into four groups according to their diameter: 0-2, 2-4, 4-6 mm, and greater than 6 mm. The follicular fluid was directly aspirated from the follicles and mixed according to follicular size, and two-dimensional gel e...

The differential diagnosis of a follicular lesion/neoplasm in thyroid FNA specimens includes hyperplastic/adenomatoid nodule, follicular adenoma and carcinoma, and follicular variant of papillary thyroid carcinoma. In our laboratory we separate follicular lesions of thyroid into hyperplastic/adenomatoid nodule (HN), follicular neoplasm (FON) and follicular derived neoplasm with focal nuclear fe...

Follicular growth, circulating estradiol concentrations and endometrial prostaglandin F2 alpha (PGF2 alpha) production were measured to determine whether there is an interrelationship among these factors associated with luteolysis. Follicular growth was monitored by rectal palpation every other day during diestrus in 16 mares. Plasma estradiol was determined for daily samples during all estrous...

Growth differentiation factor 9 (GDF-9) and bone morphogenetic protein 15 (BMP-15) play important functions in follicular and oocyte development in many species. This study evaluated the dynamic expression of GDF-9 and BMP-15 in canine follicles cells using flow cytometry analysis. Follicular cells were removed from three sizes of antral follicles (small, medium and large) from ovaries of bitch...

The weaning to estrus and weaning to ovulation intervals in sows are controlled by ovarian follicular growth after weaning. Longer intervals could be caused by smaller diameter follicles at weaning that take more time to reach a preovulatory size. We addressed this hypothesis by decreasing the diameter of follicular populations before weaning and then measuring follicular development and interv...

This paper investigates the relationship of features of in-vitro fertilization (IVF) embryos and the associated oocyte and follicle to the outcome of transfer. It differs from previous studies in including a range of features (n = 53) and in using class probability tree analysis. This is a non-parametric multivariate method which expresses relationships as simple rules of features characterizin...

Follicles from goat and sheep ovaries were characterized for their biochemical and hormonal parameters to investigate the effect of developmental stage of follicles on ovarian steroidogenesis. The follicles were isolated mechanically from follicular and luteal phase ovaries and divided in 6 morphologically different groups (small, medium and large follicular and small, medium and large luteal)....

A series of 88 conventional follicular and Hürthle cell thyroid tumors were analyzed for RAS mutations and PAX8-PPAR gamma rearrangements using molecular methods and for galectin-3 and HBME-1 expression by immunohistochemistry. A novel LightCycler technology-based method was developed to detect point mutations in codons 12/13 and 61 of the H-RAS, K-RAS, and N-RAS genes. Forty-nine percent of co...

Vaginal ultrasonography of uterine peristalsis during the follicular phase of the menstrual cycle demonstrates an increasing frequency and intensity of subendometrial and myometrial peristaltic waves as the follicular phase progresses. During this time the numbers of contraction waves with a fundo-cervical direction decrease considerably in favour of waves of contraction with a cervico-fundal d...

This study was designed to evaluate the amounts of coagulation factors and to determine whether the protein profile in pre-ovulatory ovarian follicular fluid aspirated from ovaries collected from mares at slaughter are representative of that in follicular fluid collected from live animals. The proteins evaluated included, (i) albumin, ceruloplasmin and fibronectin, (ii) the procoagulant plasma ...
