Some of the major serum proteins that are also found in follicular fluid, including transferrin, alpha-macroglobulin and albumin, are thought to play a role in oocyte maturation. This study set out to identify proteins in human follicular fluid by capillary zone electrophoresis and to investigate their relationship to follicular/oocyte maturity and fertility outcome. 176 individual follicular f...

Ovary is an important organ that houses the oocytes (reproductive cell). Oocyte growth depends on the function of follicular cells such as the granulosa and theca cells. Two-cell two gonadotropin systems are associated with oocyte growth and follicular cell functions. In addition to these systems, it is also known that several growth factors regulate oocyte growth and follicular cell functions....

Purpose: To investigate the impact of quantitative FDG-Metabolic activity of non-iodine avid Loco-regional recurrence [LRR; thyroid recurrence and/or cervical node metastasis] on therapy selection in thyroid cancer patients with elevated thyroglobulin [TG]. Methods: Forty thyroid cancer [33 papillary and 7 follicular] patients who underwent FDG PET/CT were studied [with TSH>30 mU/L]. Those with...

One of the critical issues in thyroid cancer diagnostic is differentiation between follicular adenoma, follicular carcinoma and the follicular variant of papillary carcinoma, which in some cases is not possible based on histopathological features only. In this paper we performed molecular profiling of thyroid tissue aiming to identify metabolites characteristic for different types of thyroid ca...

Affinity maturation of antibodies during immune responses is achieved by multiple rounds of somatic hypermutation and subsequent preferential selection of those B cells that express B cell receptors with improved binding characteristics for the antigen. The mechanism underlying B cell selection has not yet been defined. By employing an agent-based model, we show that for physiologically reasona...

Eosinophilic pustular folliculitis is characterized by an eosinophil-rich inflammatory follicular and perifollicular infiltrate primarily centred at the level of the follicular isthmus and sebaceous duct. Follicular mucinosis has been observed in lesions of eosinophilic pustular folliculitis. Clinical and histological features of eosinophilic pustular folliculitis with follicular mucinosis and ...

More than one-half of adults with non-Hodgkin's B cell lymphomas present with low-grade follicular lymphomas. These tumor cells are found in close association with follicular T lymphocytes and dendritic cells, suggesting that the surrounding cells may play a role in the support of follicular tumors. Supernatants from activated human peripheral blood lymphocytes were found to promote the in vitr...

  To study viability and activity of isolated common carp, Cyprinus carpio, ovarian follicular cells (granulosa and theca cells), 17- α -Hydroxy progesterone (17 α -OHP) and 17 β -Estradiol (E2) levels were estimated in the culture media of cultivated carp ovarian follicular cells, using radioimmunoassay (RIA). Oocytes were isolated from the ovaries of female carp. Interstitial tissue was manua...

OBJECTIVE Genetic alterations involving the thyroid transcription factor PAX8 and the peroxisome proliferator-activated receptor gamma 1 (PPARgamma1) genes have been described in thyroid neoplasms. We investigated in a series of thyroid samples, including 14 normal, 13 hyperfunctioning tissues, 26 follicular adenomas, 21 follicular and 41 papillary carcinomas, both the frequency of the PAX8-PPA...

BACKGROUND Nodular follicular lesions of thyroid gland comprise benign and malignant neoplasms, as well as some forms of hyperplasia. "Follicular" refers to origin of cells and in the same time to growth pattern - building follicles. Nodular follicular thyroid lesions have in common many morphological features, therefore attempts were made to define additional criteria for distinction between f...
