The aim of this study was to compare the efficacy of pure follicle stimulating hormone (FSH) with that of FSH/human menopausal gonadotrophin (HMG) combination in downregulated cycles. A total of 357 patients was evaluated retrospectively. Sixty percent of patients in the FSH group and 55% in the FSH/HMG group were new; the others were repeat patients. Ovulation was suppressed with leuprolide ac...

The objective of this study was to compare the live birth rates resulting from ovarian stimulation with highly purified human menopausal gonadotrophin (HP-HMG), which combines FSH and human chorionic gonadotrophin-driven LH activities, or recombinant FSH (rFSH) alone in women undergoing IVF cycles. An integrated analysis was performed of the raw data from two randomized controlled trials that w...

The activity, expression and function of phosphodiesterase 4 (PDE 4) were investigated in the HMG human gingiva-derived malignant melanoma cell line. A specific PDE4 inhibitor, rolipram, inhibited PDE activity in homogenates of HMG cells, and PDE4B and 4D mRNAs were detected by RT-PCR in RNA from HMG cells. Two specific PDE4 inhibitors, rolipram and Ro-20-1724, and an adenylate cyclase activato...

Seventeen hours after a single oral dose of the cyclic monoterpenes cineole or menthol, rat liver 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase activity was inhibited by up to 70%. The transient nature of this effect (no inhibition 41 h after dosing) was compatible with the rapid metabolism and excretion of these terpenes. Neither menthol, and its major metabolite, menthylglucuronid...

The chemical warfare agent analog, 2-chloroethyl ethyl sulfide, known as 'half-mustard gas' (HMG), is less toxic and less of an environmental hazard than the full molecule and has been shown to produce an acute lung injury in rats when instilled via intrapulmonary injection. This injury is characterized by massive, localized hemorrhage and edema into the alveolar compartment and can be quantita...

The microsomal enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase catalyzes the rate-limiting step in the cholesterogenic pathway and was proposed to be composed in situ of 2 noncovalently linked subunits (Edwards, P.A., Kempner, E.S., Lan, S.-F., and Erickson, S.K. (1985) J. Biol. Chem. 260, 10278-10282). In the present report, the activities and kinetic properties of HMG-CoA red...

This work presents an idea about to design, simulation, and analysis of operational control system in order supervise the operations a hybrid AC/DC microgrid (HMG) different operating modes (connected islanded). The main task this paper is concerned with development implementation global optimization method for solving problems energy crisis HMG adequate algorithm. supervision was developed suc...

The octamer motif (ATTTGCAT) present in several eukaryotic promoters and enhancers is now known to influence the transcription of several genes by interacting with members of a broad family of homeodomain proteins. The promoter of the human class II MHC gene HLA-DRA contains a conserved octamer element that can bind (among other proteins) the transcription factor Oct-2A and the high mobility gr...

Pilot-scale libraries of eight-membered medium ring lactams (MRLs) and related tricyclic compounds (either seven-membered lactams, thiolactams or amines) were screened for their ability to inhibit the catalytic activity of human recombinant 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase in vitro. A dozen of the synthetic compounds mimic the inhibition of purified HMG-CoA reductase ac...

Background: Ovarian cortex xenotransplantation into immunodeficient rats is a follicles protection method in rare animals and investigation on folliclogenesis. The aim of this study was to evaluate the effects of gonadotropin and erythropoietin (EPO) treatment on follicular development in the transplanted ovaries. Materials and Methods: Prepared sheep ovarian cortical strips were vitrified by c...
