BACKGROUND Follicular lymphomas are currently subdivided into grades I, II, IIIa and IIIb. This distinction is, however, questioned. DESIGN AND METHODS We studied the gene expression profile of 43 follicular lymphomas, 50 B-cell non-Hodgkin's lymphomas of different histotype, and 20 samples of normal B-lymphocytes in order to assess: (i) the relationship of follicular lymphoma with normal B c...

BACKGROUND Egg laying in Magang geese is characterized by extended interruption between clutches and lowing laying rate. Both the ovarian follicular development and ovulation characteristics, and the associated endocrine and molecular regulatory mechanisms involved are poorly understood, but could be important for guiding development of molecule aided selection of egg laying performances in gee...

Because IGFBP inhibit IGF-stimulated cellular proliferation and differentiation, it is hypothesized that variations among IGFBP in individual follicles might contribute to the regulation of recruitment, selection, dominance, and turnover of ovarian follicles. Sources of IGFBP in fluid of bovine follicles are not well established; thus, objectives of this study were to determine levels of IGFBP ...

Studies in cattle assessing changes in number and size of antral follicles, concentrations of estradiol, androgens and progesterone in serum and follicular fluid, and numbers of gonadotropin receptors per follicle during repetitive estrous cycles and postpartum anestrus are reviewed. The rate of growth of small follicles (1 to 3 mm) into larger follicles increases as the estrous cycle progresse...

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...

INTRODUCTION Most prognostic studies in differentiated carcinoma have included a high number of papillary carcinomas and few follicular carcinomas, and not all of their conclusions therefore apply to the latter. OBJECTIVE To analyze the prognostic factors of follicular thyroid carcinoma. PATIENTS AND METHODS SELECTION CRITERIA Patients with histological diagnosis of follicular carcinoma ...

BACKGROUND The aim of the present study was to determine the intrafollicular concentrations of anti-Müllerian hormone (AMH), inhibin-B and steroids in normal human small antral follicles and to relate them to follicular size. METHODS A group of 103 women having one ovary removed for fertility preservation by cryopreservation prior to gonadotoxic treatment served as a source of a total of 272 ...
