AIMS To evaluate if 3 months of gonadotropin-releasing hormone analogue (GnRHa) treatment results in sufficient suppression of pubertal luteinizing hormone (LH) and follicle-stimulating hormone (FSH) profile patterns in short pubertal small for gestational age (SGA) boys. To compare growth hormone (GH) profiles and fasting insulin-like growth factor (IGF)-I and IGF-binding protein-3 (IGFBP-3) l...

Uterine leiomyoma and adenomyosis represent the most common benign tumors of the female reproductive system (Levy, 2008; Parker, 2007; Sankaran & Manyonda, 2008). These tumors are estrogen dependent, develop during the reproductive period, and are suppressed with menopause. Traditional treatments for myomas and adenomyosis have been various types of surgical techniques. Medical management of th...

This meta-analysis was designed to assess the overall performance of GnRHa in preserving the ovarian function in young women undergoing chemotherapy. Electronic literature databases including Pubmed, MEDLINE, Cochrane library, Embase, CNKI and Wanfang were searched for articles published till November, 2013. The articles written in both Chinese and English were considered. Only randomized contr...

BACKGROUND Additional treatment with a gonadotropin-releasing hormone (GnRH) agonist (GnRHa) before IVF-ET (ultralong GnRHa therapy) has been reported to improve the outcome of IVF-ET in endometriosis patients. However, the mechanism of ultralong GnRHa therapy is unclear. It is suggested that inflammatory cytokines and oxidative stress contribute to infertility in endometriosis patients. Theref...

Objective To compare the efficacy and safety of high-intensity focused ultrasound (HIFU) gonadotropin-releasing analogues (GnRH-a) as pretreatments for hysteroscopic transcervical resection myoma (TCRM) type 2 submucosal fibroids greater than 4 centimeters in diameter.Materials methods Seventy-nine patients were assigned into two groups according patient preference: 42 HIFU 37 GnRHa. TCRM was p...

Gonadotropin-releasing hormone (GnRH) is secreted from neurons within the hypothalamus and is necessary for reproductive function in all vertebrates. GnRH is also found in organs outside of the brain and plays an important role in Leydig cell steroidogenesis in the testis. However, the signalling pathways mediating this function remain largely unknown. In this study, we investigated whether com...

A consensus protocol enables a system of n asynchronous processes, some of them faulty, to reach agreement. Both the processes and the message system are capable of cooperating to prevent the correct processes from reaching decision. A protocol is t-resilient if in the presence of up to t faulty processes it reaches agreement with probability 1. Byzantine processes are faulty processes that can...

identification of exogenous factors affecting spermatogonial stem cells (sscs) proliferation in vitro, provides worthy ways to study the basic biology of the cells. the aim of this study was to investigate the effects of a gnrh analogue (alareline acetate) on sscs colonization in short-term co-culture with sertoli cells. five, three-month old holstein male calves were used to isolate spermatogo...

The effects of treatment of patients with gonadotrophin-releasing hormone analogue (GnRHa) combined with purified follicle stimulating hormone (FSH) for in-vitro fertilization (IVF) were investigated in detail to determine the influences of different administration routes and the degree of suppression of luteinizing hormone (LH). Responses to exogenous gonadotrophins were studied in infertile w...

The correct operation of computer protocols is essential to the smooth operation of the distributed systems that facilitate our global economy. Formal techniques provide our best chance to ensure that protocol designs are free from errors. This invited paper revisits the class of Stop-and-Wait protocols that incorporate retransmission strategies to recover from transmission errors. This is moti...
