BACKGROUND Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) serodiscordant couples with the male infected can be helped to have children minimizing the transmission risk. Our aim was to evaluate the results of our assisted reproduction programme for these couples and to develop adequate strategies for their management. METHODS Members of(More)
BACKGROUND The aim of the present study was to evaluate the implication of male factor, in terms of sperm DNA oxidation and fragmentation, and Y chromosome microdeletions in recurrent spontaneous abortion (RSA) of unknown origin in a strictly selected cohort. METHODS A prospective cohort study was carried out in a private university-affiliated setting.(More)
BACKGROUND: The main concerns for couples undergoing assisted reproduction treatment using donor gametes are the possibilities of acquiring infectious diseases and of transmitting genetic disorders to the progeny. They are also frequently concerned and interested in the cultural and psychological background of the donors. Our aim was to examine the current(More)
BACKGROUND Sperm DNA integrity has been used as a new marker of sperm quality in the prediction of pregnancy. Nevertheless, no previous study has been performed by analysing the same samples that were employed in assisted reproduction. The main objective of this work was to correlate sperm chromatin dispersion (SCD), measured by the SCD test, with semen(More)
OBJECTIVE To investigate the production and secretion of interleukin (IL)-6 and vascular endothelial growth factor (VEGF) mRNA and protein by granulosa luteal cells (GCs) in vivo and in vitro in women with and without endometriosis. DESIGN Prospective study. SETTING A private, university-affiliated assisted reproduction unit and a university center. (More)
BACKGROUND We examined the presence and function of tachykinins and the tachykinin-degrading enzymes neprilysin (NEP) and neprilysin-2 (NEP2) in human spermatozoa. METHODS Freshly ejaculated semen was collected from forty-eight normozoospermic human donors. We analyzed the expression of substance P, neurokinin A, neurokinin B, hemokinin-1, NEP and NEP2 in(More)
In this paper, we use a Moore Automata with Binary Stochastic Output Function in order to explore the extensive decision regarding tax evasion made by subjects in experiments run in Chile and Italy. Firstly, we show how an hypothesis about subject behavior is converted into an automaton, and how we compute the probabilities of evading for every state of an(More)
BACKGROUND In natural conception only a few sperm cells reach the ampulla or the site of fertilization. This population is a selected group of cells since only motile cells can pass through cervical mucus and gain initial entry into the female reproductive tract. In animals, some studies indicate that the sperm selected by the reproductive tract and(More)
Report of the results of a 2 year programme of sperm wash and ICSI treatment for human immunodeficiency virus and hepatitis C virus serodiscord-ant couples. (2005) ICSI for treatment of human immunodeficiency virus and hepatitis C virus-serodiscordant couples with infected male partner. Comparison of polymerase chain reaction-dependent methods for(More)
This paper introduces a methodology to describe and compare the economic relative performance of the hospitality sector of the Italian regions during the period 2000-2004. Dynamics of the hospitality sector of each region is represented by the evolution of its economic efficiency. The investigation involves the following steps: a static Data Envelopment(More)
