Introduction & Objective: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. According to the Rotterdam criteria, this syndrome is identified by presence of two of three criteria: (1) polycystic ovaries (2) oligo/anovulation and/or (3) clinical or biochemical evidence of hyperandrogenism. Low mature oocyte and embryo have been reported in poly...
Background: Recent studies have been conducted with the aim of improving fertility rates in FTAI programs beef females. The observation estrus expression constitutes an important indicator zebu Therefore, this work has as objective to evaluate impact on follicular, luteal and morphofunctional characteristics Nelore females synchronized for FTAI.Materials, Methods & Results: Sixty five lacta...
background: there are inter-observer disagreements between papillary thyroid carcinoma (ptc) with other follicular lesions of thyroid in aspect of diagnosis. cd56 is present on follicular epithelial cells of the normal thyroid. we evaluated the diagnostic value of cd56 expression in ptc, follicular thyroid lesions, and follicular thyroid neoplasms. materials and methods: seventythree cases diag...
introduction: in vitro maturation and development of immature oocytes, as an artificial reproduction technique, is useful especially in women who are affected by cancer and polycystic ovary syndrome. despite using many types of in vitro media, an appropriate environment has not been reported yet. present study was designed to assess the effect of heated human follicular fluid (hhff), which is s...
Argyrophilic nucleolar organiser regions (AgNORs) in 28 follicular lymphomas and 30 lymph nodes showing reactive follicular hyperplasia were studied to see if they were helpful in distinguishing follicular lymphoma from follicular hyperplasia in paraffin wax tissue sections. Mean nuclear counts were greater in follicular hyperplasia (3.71 v 3.11). This difference was significant but counts over...
Fine needle aspiration biopsy (FNAB) of the thyroid is limited in distinguishing hyperplastic nodular goiter from true follicular neoplasm and in separating follicular adenoma from follicular carcinoma. The present study was done to evaluate if the morphologic and morphometric investigations and silver staining of nucleolar organizer regions (NORs), either alone or in association would help to ...
The pathogenesis of follicular lymphoma is a multi-hit process progressing over many years through the accumulation of numerous genetic alterations. Besides the hallmark t(14;18), it is still unclear which other oncogenic hits contribute to the early steps of transformation and in which precursor stages these occur. To address this issue, we performed high-resolution comparative genomic hybridi...
The inability to distinguish microinvasive follicular thyroid cancer from benign follicular tumors preoperatively presents an important surgical dilemma. We examined 44 follicular tumors and found telomerase activity in all 11 follicular carcinomas and in 8 of 33 benign follicular tumors. It was undetectable in 22 normal thyroid tissues adjacent to the tumors. Telomerase activity may thus provi...
Objectives were to characterize changes in concentrations of LH, FSH, and estradiol-17beta (estradiol) in blood and populations of ovarian follicles of prepubertal cattle during waves of follicular development and to evaluate interactions between day after follicular aspiration and month prepuberty for these variables. During each month (month prepuberty), ovarian follicles of prepubertal cattl...
