BACKGROUND This study aimed to determine amino acid (AA), ammonia and urea concentrations in human ovarian follicular fluid and to compare these concentrations with those in the circulation. METHODS Samples of pre-ovulatory follicular fluid and peripheral venous blood were obtained from 14 IVF patients. High-performance liquid chromatography (HPLC) measurements of 25 AAs were the main outcome...
HYPOTHESIS Dipeptidyl aminopeptidase IV (DPP IV) activity in cytological samples from a follicular thyroid tumor is the most sensitive and specific indicator for the detection of follicular carcinoma of the thyroid gland. Dipeptidyl aminopeptidase IV activity is independent of cytological characteristics and superior to other clinical findings. DESIGN AND PATIENT SELECTION: Among the patients s...
During the early follicular phase in the menstrual cycle, antral follicle sizes are often markedly heterogeneous. These follicular size discrepancies may, at least in part, result from the early exposure of FSH-sensitive follicles to gradient FSH concentrations during the preceding luteal phase. In addition, they potentially affect the results of ovarian stimulation. Indeed, pre-existing follic...
Our previous study reported microorganisms in human follicular fluid. The objective of this study was to test human follicular fluid for the presence of microorganisms and to correlate these findings with the in vitro fertilization (IVF) outcomes. In this study, 263 paired follicular fluids and vaginal swabs were collected from women undergoing IVF cycles, with various causes for infertility, a...
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....
Abstract Follicular dendritic cells (FDCs) retain immune complexes (ICs) for prolonged time periods and are important germinal center (GC) reactions. ICs undergo periodic cycling in FDCs, a mechanism supporting an extended half-life of Ag. Based on experimental data, we estimated that the average residence PE-ICs FDC surface interior were 21 36 min, respectively. GC simulations show Ag might im...
This study investigated how Michauxia campanuloides affects the Proliferating Cell Nuclear Antigen (PCNA) expression in granulosa cells, ovarian histomorphology and serum total antioxidant capacity (TAC) rats. Rats were divided into control (C), treatment 1 (T 1) 2 2) groups. The rats T groups received aqueous extract of M. at doses 20 mg/kg/day 40 orally for 21 days, respectively. Serum TAC le...
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...
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 ...
