A formal specification and proof of correctness is given of the sliding­ window protocol using the notation of Communicating Sequential Pro­ cesses. First the stop-and-wait protocol is defined; its correetne8S, that it forms a I-place buffer, is almost evident. Next the alternating-bit protocol is defined and described in terms of the stop-and-wait proto­ col, and its correctness deduced. Final...

Adolescents with gender dysphoria experience incongruence between their assigned and their experienced gende [1]. Gender reassignment therapy aims to achieve transition to the desired gender and includes psychological, hormonal and surgical interventions. Puberty can be suspended using gonadotropin releasing hormone analogues (GnRHa) thus preventing development in the direction of the natal gen...

Introduction Uterine fibroids are the most common benign tumor in women in Kazakhstan. In the past two decades, endoscopic surgery has played an important role in the development of gynecologic surgery, particularly in the treatment of uterine fibroids. The goal of this paper is to evaluate whether uterine artery embolization (UAE) or gonadotropin-releasing hormone agonists (GnRHa) prior to myo...

results from 110 subjects with cpp, 46 girls (41.8%) were considered as intervention and 64 (58.2%) as control groups. the mean age at initial visit was 7.46 ± 1.03 years. the bmi standard deviation scores in both groups was not significantly different at sixth and 12th months of treatment compared with baseline (p = 0.257 and p = 0.839, respectively). the prevalence of obesity was not signific...

Gonadotropin releasing hormone analogues (GnRHa) are often used to regress endometriosis implants and prevent premature luteinizing hormone surges in women undergoing controlled ovarian stimulation. In addition to GnRH central action, the expression of GnRH and receptors in the endometrium implies an autocrine/paracrine role for GnRH and an additional site of action for GnRHa. To further examin...

A discrete-time communication framework is studied under an approximate socalled "stop protocol" related to the lost-calls-held protocol. An explicit insensitive product form expression as recently obtained under a less realistic recirculated protocol is shown to remain valid. This extension seems of both practical and theoretical interest. Applications include: • Circuit switching structures •...

Background Follicle stimulating hormone and testosterone stimulate Sertoli cells to support germ cell function and differentiation. During mini-puberty, when gonadotropin (GnRH) stimulates increases in plasma luteinizing hormone (LH) and testosterone levels, gonocytes are transformed into Ad spermatogonia. In cryptorchidism, impaired gonadotropin secretion during mini-puberty results in insuffi...

Gonadotropin-releasing hormone (GnRH) receptor is present in 80% of ovarian cancer, and numerous studies have provided evidence for a role of GnRH in cell proliferation. In this study, the effect of GnRH on the invasion potential of ovarian cancer cells was investigated. In vitro migration and cell invasion assays with the ovarian cancer cell lines Caov-3 and OVCAR-3 revealed the biphasic natur...
