The microenvironment of the developing follicle is critical to the acquisition of oocyte developmental competence, which is influenced by several factors including follicle size and season. The aim of this study was to characterise the metabolomic signatures of porcine follicular fluid (FF) collected from good and poor follicular environments, using high-resolution proton nuclear magnetic reson...

polycystic ovarian syndrome is a hetrogenous condition with a broad clinical and pathologic spectrum that may reflect the effects of diverse etiologic factors. polycystic ovarian syndrome is an abnormality in the maturation of the follicles which can result in abnormal composition of follicular fluid. by analysis and comparison of the biochemical composition of human follicular fluid in normal ...

This study investigated follicular development during and after postweaning altrenogest treatment of primiparous sows in relation to subsequent reproductive performance. Primiparous sows (n = 259) were randomly assigned at weaning (d 0) to 1 of 4 groups: control (no altrenogest, n = 71), RU4 (20 mg of altrenogest from d -1 to 2, n = 62), RU8 (20 mg of altrenogest from d -1 to 6, n = 65), or RU1...

The incidence of thyroid and the prevalence of follicular carcinoma is rare in childhood and adolescents; however, it is considered as the second most common pediatric thyroid malignancy. Vascular invasion, distant metastasis, and tumor size greater than 4 cm are among the factors leading to total thyroidectomy followed by radioactive iodine therapy. The tumor size of the case in this study was...

In a previous study, we showed that follicle size at weaning affects the response of a sow to a short-term altrenogest treatment after weaning. In this study, an attempt was made to prevent the growth of follicles into larger size categories before weaning by using different altrenogest treatments before weaning to improve reproductive performance after postweaning altrenogest treatments. Sows ...

background: the following study was carried out to determine the ultrastructural features of the oocyte of the ovulatory-sized follicles in relation to concentrations of steroids and igf-i in the follicular fluid and serum in the dromedary camel. methods: camel follicles with a clear and healthy appearance were categorized into three classes: follicles 10 to 13.9, 14-17.9 and 18-30 mm diameter....

Feed sorting is a natural behavior of dairy cows that can result in inconsistencies in the nutritive value of a total mixed ration (TMR). The objective of this study was to determine the effects of replacing high-moisture corn with glycerol on feed sorting and the feed intake pattern of transition dairy cows. Multiparous Holstein cows (n=26) were paired by expected calving date, housed in indiv...

This paper summarizes research dealing with the induction of spontaneous superovulation in the cyclic hamster by single injections of PMSG. Four principal approaches have been used : 1) ovulation rate as an endpoint ; 2) number and size of follicles, and staging of follicular development in serially sectioned ovaries ; 3) determining the effects of an antiserum to PMSG ; 4) measuring steroid an...

BACKGROUND The occurrence of skin metastases are rare events in the course of a follicular thyroid carcinoma (FTC) and usually indicate advanced tumor stages. The scalp is the most affected area of these metastases. CASE PRESENTATION We present a case of a 76 year old Woman with multiple giant scalp metastases of a follicular carcinoma. These metastases had been resected and wounds had been c...

The size of ovarian follicular population evaluated by direct antral follicular count or endocrine markers can help determine the success of reproductive biotechnologies in cattle. However, although highly repeatable within animal, the antral follicular population (AFP) appears to be greatly variable across individuals. Therefore, laboratory methods that reliably predict AFP could have a signif...
