Abstract (sommario):

The most common symptom of residual ovarian syndrome (ROS) is chronic pelvic pain. Extensive pelvic adhesions are the typical operative findings, while follicular cysts and corpus luteum hematoma were the common pathological findings of the residual ovaries. However, malignant changes are also recorded. In this case report the ROS was associated with cystic changes in size with extensive adhesion with peitoneuum, omentum and right ureter drawn and impacted within the cyst wall. Opinion of ovarian preservation during hysterectomy for benign indications and the sequelae should be discussed with

Abstract (sommario):

For the purpose of determining factors associated with ovulation induction in rabbits, there is a need to examine the ovaries in a serial fashion. To this end, a study was designed to develop an approach that would permit serial evaluation of ovarian structures in vivo using ultrasound biomicroscopy (UBM) while preserving ovarian function in rabbits. The use of UBM has enabled characterisation of ovarian dynamics in live mice and has recently been validated for assessing structures in excised rabbit ovaries (Cervantes et al. 2011 Reprod. Fertil. Dev. 23, 183–184). However, acoustic impedance o

Abstract (sommario):

Invasive methods (e.g. histology) limit serial assessment of ovarian structures in rabbits and impede progress in our understanding of factors responsible for inducing ovulation. Serial transrectal or transvaginal ultrasonography of ovarian structures has revolutionized our understanding of reproductive patterns in domestic animals, but the approach is limited in smaller species by the small physical size of the animal and the ovary. The advent of high-resolution ultrasound biomicroscopy (UBM), however, has permitted recent characterisation of ovarian dynamics in species as small as mice. As p

Stem cells have potential for therapeutic application. Continuous repair of ovarian surface epithelium following folliculogenesis and ovarian carcinoma suggests the presence of stem cells in ovarian epithelial cells. In vitro gametogenesis in livestock will result in large numbers of oocytes production from a single ovary, resulting in faster multiplication of superior germplasm of livestock species, treatment of infertile animals, and conservation of endangered species.

Abstract (sommario):

SummaryOvulation is considered an inflammatory, cytokine-mediated event. Cytokines, which are recognized as growth factors with immunoregulatory properties, are involved in many cellular processes at the ovarian level. In this sense, cytokines affect fertility and are involved in the development of different ovarian disorders such as bovine cystic ovarian disease (COD). Because it has been previously demonstrated that ovarian cells represent both sources and targets of cytokines, the aim of this study was to examine the expression of several cytokines, including IL-1β, IL-1RA, IL-1RI, IL-1RII,

Ovarian cysts are not funcional fluid-filled structures, which can spontaneously develop in the ovaries during the reproductive cycle, and secrete female hormones in increased amounts, causing irregular reproductive cycles and infertility.

AbstractSince majority (80%) of ovarian cancer patients present at an advanced stage, imaging performed on these patients have numerous findings.

Similarly, it is difficult to effectively communicate these findings in radiology reports. Structured reporting that is geared toward clinical decision-making has bee

Historically, research in ovarian biology has focused on folliculogenesis, but recently the ovarian stroma has become an exciting new frontier for research, holding critical keys to understanding complex ovarian dynamics. Ovarian follicles, which are the functional units of the ovary, comprise the ovarian parenchyma, while the ovarian stroma thus refers to the inverse or the components of the ovary that are not ovarian follicles. The ovarian stroma includes more general components such as immune cells, blood vessels, nerves, and lymphatic vessels, as well as ovary-specific components including

Abstract (sommario):

Understanding the role of lipid metabolism in ovarian physiology is crucial for the progression of reproductive biotechnology. The aim in this work was to explore the lipid composition and dynamics of ovarian tissue, specifically the stroma, follicles, and corpora lutea. Desorption electrospray ionization–mass spectrometry (DESI-MS), an ambient ionization technique, was applied in this investigation, acquiring chemical and spatial information simultaneously. A morphologically-friendly solvent, dimethylformamide-acetonitrile (1 : 1), was used for DESI-MS imaging which allowed for ovarian lipid

Abstract (sommario):

Morphometric studies of uteri, ovary weights, and follicle diameters were carried out to investigate possible methodological applications. Size and anatomical appearance of the uterus varied with age and phase in the estrous cycle, both in parous and nulliparous females. The uterus thus may provide valuable information on reproductive status for known-aged animals. Weight of ovaries increased in young, but declined in old females, showing significant covariance with body weight in young and prime ages. Ovary weights increased from low levels shortly after parturition to a maximum towards the e

Abstract (sommario):

Ovaries of the seasonally-breeding snow leopard (Uncia uncia) were examined to determine whether they were responsive to exogenous gonadotrophins throughout the year. The potential of laparoscopic artificial insemination (AI) also was assessed for producing offspring. During the non-breeding, pre-breeding, breeding and post-breeding seasons, females (n = 20) were treated with a standardized, dual-hormone regimen given intramuscularly (600 I.U. of equine chorionic gonadotrophin followed 80–84 h later with 300 I.U. of human chorionic gonadotrophin (hCG)). Laparoscopy was performed 45–50 h after

Abstract (sommario):

Chlamydia trachomatis is the most common bacterial cause of sexually transmitted disease and can cause pelvic inflammatory disease (PID), leading to severe outcomes such as ectopic pregnancy, infertility, or pelvic pain. We report a case of a 38-year-old patient with abdominal pain and dyspareunia. Clinical examination revealed diffuse abdominal tenderness. Vaginal and abdominal sonography showed substantial ascites and CA-125 level was elevated. Therefore, the attendant physician performed an abdominal CT scan for further diagnosis. Radiographically diffuse peritoneal enhancement, consistent

Abstract (sommario):

The occurrence of cell reabsorption in the ovaries of queens in several rates of laying eggs, artificially impeded of laying, and in nurse workers, of Apis mellifera (Linnaeus, 1758), was studied with light (LM) and transmission electron microscopy (TEM). Two types of structures were described and named by analogy with vertebrates ovarian structures, as corpus luteus, when resulting from the reabsorption of the follicular cells after ovulation, and corpus atresicus when resulting from total follicular reabsorption at any oocyte developmental stage. These structures have the same morphological

Abstract (sommario):

Abstract Zearalenone is an estrogenic mycotoxin that often contaminates plant material used in the production of feeds for companion animals. Small daily doses of ingested zearalenone - a competitive substrate modulating the activity of enzymes participating in estrogen biosynthesis at the pre-receptor level - can induce subclinical symptoms of hyperestrogenism in bitches. The objective of this study was to determine the effects of low zearalenone doses on the presence of estrogen receptors in the ovaries of pre-pubertal Beagle bitches. The bitches were divided into three groups of 10 animals

Abstract (sommario):

Siberian hamster reproduction is mediated by photoperiod-induced changes in gonadal activity. However, little is known about how photoperiod induces cellular changes in ovarian function. We hypothesized that exposing female hamsters to short (inhibitory) as opposed to long (control) photoperiods would induce an apoptosis-mediated disruption of ovarian function. Ovaries and plasma from hamsters exposed to either long (LD, 16 h light:8 h darkness) or short (SD, 8 h light:16 h darkness) days were collected during diestrus II after 3, 6, 9 and 12 weeks and processed for histology or RIA respective
