Studies were conducted to compare continuous vs pulsatile i.v. infusion of GnRH on serum gonadotropin concentrations and ovulation in seasonally anestrous mares and in cycling mares. Anestrous mares (Exp. 1) received no treatment (control; n = 3), 2, or 20 micrograms of GnRH/h continuous infusion (CI) (n = 4 and n = 6, respectively), or 20 micrograms of GnRH/h pulsatile infusion (PI) (n = 5). A...

INTRODUCTION Congenital (CI) and perinatal cytomegalovirus (CMV) infections (PI) can be linked to maternal CMV seropositivity, with fatal consequences in preterm newborns. GB genotyping has been used to analyze genotypic similarity in mothers and infants. The frequency of CMV infection in the context of maternal seropositivity and the viral gB genotypes as well as the genotypic similarity in mo...

OBJECTIVE To compare important outcomes between early tracheostomy (ET) and late tracheostomy (LT) or prolonged intubation (PI) for critically ill patients receiving long-term ventilation during their treatment. METHOD We performed computerized searches for relevant articles on PubMed, EMBASE, and the Cochrane register of controlled trials (up to July 2013). We contacted international experts...

A low power switched-capacitor (SC) integrator based on a capacitive charge-pump (CP) is proposed. The CP integrator circuit consumes approximately a quarter of the power of a conventional SC integrator while maintaining the same thermal noise performance. Power consumption of the CP integrator is analysed and compared with a conventional parasitic-insensitive integrator. Simulation results ver...

OBJECTIVE To compare the immunological response to highly active antiretroviral therapy (HAART) in treatment-naive patients with a baseline CD4 count of <200 cells/mm(3). DESIGN AND METHODS We identified treatment-naive human immunodeficiency virus (HIV-1)-infected individuals who had commenced HAART since 1996 and who had a starting CD4 count of <200 cells/mm(3). Immunological success was de...

BACKGROUND This analysis assessed the acquisition (incidence) and persistence (clearance) of human papilloma virus (HPV) infection by self-reported race among men in The HPV in Men (HIM) Study, a multinational prospective study of the natural history of genital HPV infections. METHODS Self-reported race was categorized as White, Black, Asian/Pacific Islander (PI), or multiple and mixed race. ...

We examine a new second-order integrator recently found by Omelyan et al. The integration error of the new integrator measured in the root mean square of the energy difference, 1/2, is about 10 times smaller than that of the standard second-order leapfrog (2LF) integrator. As a result, the step size of the new integrator can be made about three times larger. Taking into account a facto...

We study low-gain (P)roportional (I)ntegral control of multivariate discrete-time, forced Lur'e systems to solve the output-tracking problem for constant reference signals. formulate an incremental sector condition which is sufficient a usual linear PI controller achieve exponential disturbance-to-state and disturbance-to-tracking-error stability in closed-loop, all sufficiently small integrato...

The aim of this retrospective study was to evaluate the effect of removable partial dentures in periodontal abutment teeth in relation to the type of denture support and design of RPD in a five-year worn period. Methods : A total of 64 patients with removable partial dentures (RPDs), participated in this study. It were examined ninety-one RPDs. There were seventy-five RPDs with clasp-retained a...

in this paper, at first we mention to some results related to pi and vertex co-pi indices and then we introduce the edge versions of co-pi indices. then, we obtain some properties about these new indices.
