Citing a fairly detailed review of the literature on this issue, the author comes to the conclusion that cysts in the uterus can be of two kinds: either as a retention formation from the glands of the uterine mucosa, or the remnants of the Wolf's ducts develop. In addition, similar formations were observed with a double uterine cavity, if atresia was present in one half and fluid accumulated in it (hydrometra or haematometra).

The aim of this paper is to identify the impact of environmental turbulence on the risk of cooperation in technological entrepreneurship. Multidimensional factors such as the risk of cooperation, environmental turbulence, and the reaction to operationalized changes were selected during the literature review, and were subjected to empirical verification on a 304 element sample of SMEs, which are implementing technology entrepreneurship. The study used a questionnaire interview technique conducted directly in the company, and the research tool was a specially prepared questionnaire. Because of the multidimensional character of the studied variables, structural modelling was chosen. In addition, the influence of selected mediators and moderators on the relationship between the turbulence of the environment and the risk of cooperation in technological entrepreneurship was examined. The article has been divided into five main sections. The first section constitutes the introduction to the deliberations. A detailed review of the literature, taking into account the principles of operationalization of each of the presented variables, is discussed in the second section. The methodology used is then presented. In the next section of the paper, the results of the research are presented and then a broad discussion of these results is undertaken. The last section is a summary of the conducted research and its limitations. Knowledge about the antecedents of cooperation risk allows for the minimization of the presence of adverse phenomena, while knowledge of the directions of their impact greatly enriches the experience in the management of this type of relationship. The presented research may contribute to the construction of a rational model of the cooperation risk management process, in particular, in the case of adopting resources existing within the organization.

Gain Access

To better document the timing of ovulation and fertilization, female reproductive tracts were collected every 12 h from captive-bred fruit bats (Carollia perspicillata) on days 1–3 postcoitum and examined histologically. This also permitted observations on sperm transport, storage, and disposition. As the animals had previously been sexually segregated, most had been cycling and possessed menstrual uteri at the time of collection. Menstruation is periovulatory in this species. A widespread, headfirst orientation of spermatozoa to the uterine mucosa was observed in specimens apparently collected soon after insemination. Thereafter, however, this relationship was limited in most cases to the area around the entrance of each uterotubal junction (UTJ). A small number of spermatozoa also colonized the UTJs, which functioned as temporary sperm reservoirs on days 1–2. AlthoughC. perspicillatais monovular, no consistent differences were observed between the two oviducts in the pattern of sperm storage and release. Very few sperm were ever observed in the isthmus or ampulla (the site of fertilization). Menstrual debris (including fine particulate matter) and leukocytes present in the uterine cavity in most tracts did not gain access to the UTJ with the spermatozoa. Smooth muscle and abundant elastic fibers in the wall of the intramural UTJ, as well as receptors on its luminal epithelial cells, may play roles in the selective transport of spermatozoa to the fertilization site. While some spermatozoa are phagocytosed in the uterine lumen or by epithelial cells in the UTJ, the fate of most is probably expulsion into the vagina.

Peer-mediated academic interventions (PMAIs) have a robust evidence base that support their use in classrooms to improve a variety of academic behaviors. In this chapter, we define PMAIs, discuss strengths and challenges of using these interventions in classrooms with diverse groups of learners, and provide a detailed review of the literature to support each of four highlighted PMAIs: peer tutoring, Peer-Assisted Learning Strategies, cooperative learning, and peer-mediated writing interventions. This chapter also introduces the practical chapters in this section, which cover each of the four highlighted PMAIs.

Alternative Sites

The distribution of radioactivity in the fetus and placental structures was studied at different stages of gestation in the rabbit following the intravenous injection of radioactive iron as Fe59 sulphate. The following general results were obtained: a) A steady increase in the uptake of radioiron by the fetus and fetal placenta took place with advancing gestation. The rate of uptake showed a sharp increase at about the 20th day. b) The rate of iron transport across the placenta increased during gestation, especially in the last third of pregnancy. c) Radioiron was concentrated in the yolk sac in the early stages and in the fetal liver in the later stages of gestation. No change in the pattern of accumulation of radioiron by the fetus took place when the vessels of the yolk sac were ligated before injection. These results suggest that the yolk sac has no role in iron transport and that early in gestation it may carry on some of the functions of the fetal liver with respect to iron. d) Alternative sites of transport for iron were investigated by the injection of radioiron into the uterine cavity. The results indicate that if iron gains access to the uterine cavity, e.g. via the uterine mucosa or via the chorion and periplacental decidua, it is rapidly absorbed by the yolk sac and enters the fetus. However, such a pathway for iron transfer to the fetus does not seem to be important physiologically.

Endometrial immune response is highly associated with the homeostatic balance of the uterus and embryo development; however, the underlying molecular regulatory mechanisms are not fully elucidated. Herein, the porcine endometrium showed significant variation in mucosal immunity in proliferative and secretory phases by single-cell RNA sequencing. The loose arrangement and high motility of the uterine epithelium in the proliferative phase gave opportunities for epithelial cells and dendritic cells to cross talk with colonizing microbial community, guiding lymphocyte migration into the mucosal and glandular epithelium. The migrating lymphocytes were primarily NK and CD8+ T cells, which were robustly modulated by the chemokine signaling. In the secretory phase, the significantly strengthened mechanical mucosal barrier and increased immunoglobulin A alleviated the migration of lymphocytes into the epithelium when the neuro-modulation, mineral uptake, and amino acid metabolism were strongly upregulated. The noticeably increased intraepithelial lymphocytes were positively modulated by the bacteria in the uterine cavity. Our findings illustrated that significant mucosal immunity variation in the endometrium in the proliferative and secretory phases was closely related to intraepithelial lymphocyte migration, which could be modulated by the colonizing bacteria after cross talk with epithelial cells with higher expressions of chemokine.

Extreme Variability

Endometriosis is defined as the presence of functioning endometrial tissue outside the uterine cavity. This disease is one of the most common gynecologic disorders in reproductive age women. It generally occurs in pelvic cavity. But extrapelvic location has been defined (such as extremities, central nervous system, lungs, pleurae, liver, umbilicus, pericardium, urinary tract, intestines, and surgical scar tissue). Scar endometriosis is a rare disease and defined as presence of endometriotic lesions on the abdominal (such as cesarean section and hysterectomy) or vaginal (episiotomy) excision line. It is difficult to diagnose due to the extreme variability in presentation. The symptoms are nonspecific, typically involving pain, swelling at the incision site at the time of menstruation. Excision and histopathologic examination are necessary for diagnosis. We present a case series of obstetric scar endometriosis and review of the literature.
