OBJECTIVE To evaluate the efficacy of two doses of recombinant (r)LH, 75 IU (recommended) or 37.5 IU, for follicular stimulation and outcomes in a randomized cohort of IVF patients. DESIGN Randomized, prospective analysis. SETTING Private hospital incorporating an established IVF center. PATIENT(S) Women undergoing IVF who had a body mass index >18 or <35 and no abnormal karyotype, anovul...

The surface characterization of materials after Robot Laser Hardening (RLH) is a technically demanding procedure. RLH commonly used to harden parts, especially when subject wear. By changing their properties, this treatment can offer several benefits such as lower costs for additional machining, no use cooling agents or chemicals, high flexibility, local hardening, minimal deformation, accuracy...

BACKGROUND Poor ovarian response is a common clinical problem, affecting up to 26% of IVF cycles. For these women, addition of recombinant luteinizing hormone (rLH) to ovarian hyperstimulation with recombinant FSH has a beneficial effect on ongoing pregnancy rates, but its effect on the yield of top-quality embryos is unknown. METHODS We conducted a randomized controlled trial in women expect...

BACKGROUND Reactive lymphoid hyperplasia (RLH) of the liver is very rarely reported, and we encountered two cases of RLH of the liver in a patient with colon cancer. CASE PRESENTATION In the first case, a 77-year-old woman was admitted for the surgical removal of a ascending colon cancer. A hepatic tumor in the left lobe was concurrently revealed by computed tomography (CT), and magnetic reso...

Commonly, female European eels are injected weekly with pituitary extract (PE) from carp (CPE) or salmon (SPE) to induce sexual maturation. However, a PE is mixture of gonadotropins and other hormones that not specific for eel rapidly cleared circulation. The aim this study was therefore test the effects highly stable eel-specific recombinant (rGTHs) on oocyte development in vitro vivo eels. Fo...

BACKGROUND: Until recently, human menopausal gonadotrophin (HMG), a urinary extract containing a fixed combination of LH and FSH, was the only source of exogenous LH for women with hypogonadotrophic hypogonadism undergoing ovulation induction with gonadotrophins. Recombinant human LH (rLH) is now available for clinical use, providing a new treatment option but clinical data on its use are scant...

RATIONALE Conjunctival lymphoproliferative lesions constitute a significant diagnostic challenge and it is essential to exclude neoplastic lesions. Histopathological and immunohistochemical tests are very useful in establishing the correct diagnosis. Reactive lymphoid hyperplasia (RLH) is part of a spectrum of lymphocytic infiltrative disorders. Evidence is scarce regarding appropriate treatmen...

Background. Reactive lymphoid hyperplasia (RLH) of the liver is a benign focal liver mass that may mimic a malignant liver tumor. Although rarely encountered in clinical practice, it often poses diagnostic and management dilemmas. Methods. Cases diagnosed as hepatic RLH between January 1996 and June 2011 were investigated in a retrospective study. Clinicopathological features as well as follow-...

The results of several studies about the effectiveness of recombinant luteinizing hormone (rLH) supplementation in poor responder in vitro fertilization (IVF) patients were conflicting. To evaluate the current available data regarding the efficacy of rLH supplementation in poor responders, a meta-analysis was performed. A systemic search was performed without language limitation but restricted ...

Controlled ovarian stimulation, using a gonadotrophin-releasing hormone (GnRH) antagonist protocol, is a potential treatment option for women with a low response to other fertility treatments as it appears to be at least as effective as GnRH agonists (long protocol). However, previous studies have indicated that the administration of GnRH antagonist may cause an excessive reduction in endogenou...
