Five pony and 5 saddle-type mares were used to compare total ovarian follicular populations between breeds. The animals were hemi-ovariectomized at the preovulatory stage during the breeding season and the ovary bearing the large preovulatory follicle was studied using histological techniques. Pony and saddle-type mares did not differ as to mean number of primordial follicles, mean number of gr...

An attempt was made to describe the updated information about the factors to be concerned before using of buffalo follicular fluid for supplementation in vitro of buffalo oocyte. There are not only diameter of the follicle, the present of corpus luteum (CL), growth of follicles, stage of estrus cycle, healthy and atretic state of the ovarian follicles. The progesterone and estradiol-17B concent...

OBJECTIVE To determine factors that affect survival in patients with Hürthle cell carcinoma of the thyroid gland. METHODS Data for all cases of Hürthle cell carcinoma that occurred between January 1, 1988, and December 31, 1998, were extracted from the Surveillance, Epidemiology, and End Results database. Clinical data regarding age, sex, tumor size, primary site extension, nodal involvement,...

Malignant tumors arising from follicular cysts are rare. Herein, we report of a 62-year-old Japanese woman with a slowly growing tumor, 22 × 20 mm in size, located on her nose for 2 years. Histopathological examination of the surgically excised tumor showed that the tumor cells were basaloid and formed peripheral palisading patterns. The tumor contained a cystic structure in its center, and the...

Objective: Aim of this study was to identify the necessity of use of exogenous or surrogate LH for triggering of ovulation in induced cycles. Materials and methods: This study was conducted in Infertility Care and Research Center (ICRC) Dhaka, Bangladesh. Three hundred anovulatory patients with polycystic ovarian syndrome (PCOS) were the target population for this study. The patients were treat...

BACKGROUND Ovarian follicular activity in serial hormone profiles has been reported in up to 86% of patients with primary ovarian insufficiency (POI). In most of these studies, patients had a short duration of amenorrhea or irregular menstrual cycles which could influence the occurrence of spontaneous follicular activity. The aim was to study the incidence of follicular activity in serial hormo...

BACKGROUND This study was conducted to investigate the mechanisms by which coasting may be effective in decreasing the incidence of ovarian hyperstimulation syndrome (OHSS). METHODS A total of 160 women (patients and oocyte donors) undergoing coasting and 116 controls were included in the study. Serum, follicular fluid and granulosa cells were collected on the day of oocyte retrieval. Vascula...

BACKGROUND Administration of recombinant luteinizing hormone (rLH) in controlled ovarian hyperstimulation may benefit a subpopulation of patients. However, late follicular phase administration of high doses of rLH may also reduce the size of the follicular cohort and promote monofollicular development. METHODS To determine if rLH in late follicular development had a negative impact on follicu...

Lagostomus maximus is a notable mammalian model for reproductive studies. Females have an extremely high ovulation rate, which is due to down-regulation of the follicular apoptosis pathway, which ensures a large pool of developing follicles. This large pool is supported by the convoluted anatomy of the mature ovary, whose germinal tissue is found in irregularly curved ridges throughout the cort...

Thyroid carcinomas constitute lesions with an ascending incidence, for which many prognosis assessment systems were developed. This study focused on analyzing the immunoexpression of CK19, vimentin and E-cadherin in a number of 43 differentiated thyroid carcinomas, of which 39 papillary carcinomas and four follicular carcinomas, and assessed the relationship of these markers with clinico-pathol...
