Ring canals connecting Drosophila germline, follicle and imaginal disc cells provide direct contact of cytoplasm between cells. To date, little is known about the formation, structure, or function of the somatic ring canals present in follicle and imaginal disc cells. Here, we show by confocal and electron microscopy that Pavarotti kinesin-like protein and Visgun are stable components of somati...

Background Endometriosis has been widely implicated as one of the causes of chronic pelvic pain, dysmenorrhea and infertility. The purpose of our study was to define the presumed correlation between visual and histologic diagnostic features of endometriosis based on the peritoneal findings identified in laparoscopy as a diagnostic trial with a standardized technique. So, all the specimens inclu...

The sizes of follicle centre cells in 15 specimens of follicular (centroblastic-centrocytic) non-Hodgkin's lymphoma and 15 specimens of reactive follicular hyperplasia have been measured. The findings differ from previous studies, where nuclei of cells from follicle centres and interfollicular areas were measured and revealed no significant difference between follicular lymphoma and reactive fo...

Objectives To assess the relationship between dental follicle width and maxillary impacted canines' descriptive and resorptive features with three-dimensional (3D) cone-beam computed tomography (CBCT). Methods The study comprised 102 patients with cone-beam computed tomography 3D images and a total of 140 impacted canines. The association between maxillary impacted canine dental follicle widt...

The microenvironment of the developing follicle is critical to the acquisition of oocyte developmental competence, which is influenced by several factors including follicle size and season. The aim of this study was to characterise the metabolomic signatures of porcine follicular fluid (FF) collected from good and poor follicular environments, using high-resolution proton nuclear magnetic reson...

background: previous studies reported many discrepancies about the effects of corpus luteum (cl) and ovarian follicle size on the developmental competence of oocytes. objective: the aim of this study was to investigate the effects of cl and different size of follicle on the developmental potential of bovine oocytes. materials and methods: after ovarian classification based on presence or absenc...

Administration of gonadotropin-releasing hormone (GnRH) induces a surge of luteinizing hormone and ovulation in a variety of species, including human beings. Our objectives were to determine the effect of follicle size at the time of ovulation on corpus luteum function and establishment and maintenance of pregnancy in cows in which ovulation was either spontaneous or induced with GnRH. GnRH-ind...

The ovarian follicle is the functional unit of the ovary that secretes sex hormones and supports oocyte maturation. In vitro follicle techniques provide a tool to model follicle development in order to investigate basic biology, and are further being developed as a technique to preserve fertility in the clinic. Our in vitro culture system employs hydrogels in order to mimic the native ovarian e...

OBJECTIVE To investigate the relation between reproductive age and ultrasound (US)-based follicle counts and the reproducibility of follicle counts in regularly cycling women with proven fertility. DESIGN Prospective observational study. SETTING Tertiary fertility center. PATIENT(S) Healthy female volunteers with proven fertility, recruited by advertisement in local newspapers. INTERVEN...
