Abstract

In order to evaluate the role of Mycoplasma pneumoniae and Chlamydia pneumoniae, we studied 613 children aged 2-14 years who were hospitalized for community-acquired lower respiratory tract infections (LRTIs). The patients were enrolled in the study by 21 centers in different regions of Italy from May 1998 through April 1999. Paired serum samples were obtained on admission and after 4-6 weeks to assay the titers of M. pneumoniae and C. pneumoniae antibodies. Nasopharyngeal aspirates for the detection of M. pneumoniae and C. pneumoniae were obtained on admission. Acute M. pneumoniae infections in 210 patients (34.3%) and acute C. pneumoniae infections in 87 (14.1%) were diagnosed. Fifteen of the 18 children with M. pneumoniae and/or C. pneumoniae infections whose treatments were considered clinical failures 4-6 weeks after enrollment had not been treated with macrolides. Our study confirms that M. pneumoniae and/or C. pneumoniae plays a significant role in community-acquired LRTIs in children of all ages and that such infections have a more complicated course when not treated with adequate antimicrobial agents.

57. ARTISTE: An Integrated Art Analysis and Navigation Environment

Author

Allen, P.J., Vaccaro, R., and Presutti, G.

Abstract

The ARTISTE project aims to build a tool for the intelligent retrieval and indexing of high resolution images. European museums and galleries are rich in cultural treasures but public access has not reached its full potential. Digital multimedia can address these issues and expand the accessible collections. However, there is a lack of systems and techniques to support both professional and citizen access to these collections. The ARTISTE project will address professional users in the fine arts as the primary end-user base. These users provide services for the ultimate end-user, the citizen.

Abstract

Flowcytometric analysis on T-cell subpopulations in the blood and cerebrospinal fluid (CSF) of 10 children with mumps meningitis (MM) revealed that the proportion of lymphocytes which bore the gamma delta T-cell receptor for antigen was significantly higher in CSF than in autologous and heterologous blood samples. gamma delta T-cell values in CSF of MM patients were also significantly higher than those calculated in CSF specimens from nine children with non-inflammatory neurological disorders. Whether and how the expanded CSF gamma delta T-lymphocyte subset, either CD8+ or double-negative (CD4-/CD8-), contributes to the eradication of mumps virus infection from the central nervous system represents a central focus of our ongoing research.

67. Gamma delta T-cell subset distribution in human semen from fertile donors

Abstract

Gamma delta T-cell subset distribution has not been fully investigated in normal human semen.We therefore carried out experiments by using a direct immunofluorescence staining technique followed by two-color cytofluorimetric analysis on mononuclear cell (MC) suspensions from ejaculates of ten healthy, fertile volunteers. Autologous peripheral blood MC were simultaneously analyzed and the results used for statistical comparison.The proportion of normal human semen lymphocytes bearing the gamma delta T-cell receptor for antigen was greatly increased compared with autologous circulating counterparts. Interestingly, the rise was mainly due to an overexpansion of cells expressing V delta 1 gene-encoded determinants on their surface. This contrasts with the normal blood picture, where most gamma delta T cells express V delta 2 conformational epitopes.The numerical and phenotypical differences in semen gamma delta T lymphocytes provide further evidence of a defined migrating lymphocyte subset balance in anatomically and physiologically distinct areas of the body. Their functional role, in terms of both helper and suppressor-cytotoxic activities in the nonsterile proximal portions of the male genital tract, now needs to be explored in detail.

Abstract

Although the relative and absolute numbers of CD3+ cells (T lymphocytes) were similar in eight children with acquired Toxoplasma gondii infection and 10 uninfected age- and sex-matched healthy controls, the proportion of cells bearing the gamma delta T-cell receptor was significantly higher in the subjects with acute toxoplasmosis. The great majority of gamma delta T cells from the infected patients expressed covalently bound gamma delta chains on their surface, i.e. were BB3+ lymphocytes. Since the gamma delta T-cell subsets exert both restricted and unrestricted major histocompatibility complex cytotoxicity, further research is needed to elucidate the role of gamma delta T cells in the control of this coccidian protozoan infection.

Abstract

Our laboratories previously reported that the proportion of lymphocytes bearing the gamma/delta T-cell receptor (TcR) is twofold greater in human milk lymphocyte suspensions than in autologous and heterologous blood samples. The present investigation shows that gamma/delta colostral T cells preferentially express non-covalently bound gamma/delta chains, whereas only a few display the disulphide-linked form of the TcR. This contrasts with the picture in the blood, where the distribution of these two nonoverlapping subpopulations is proportionally inverse. These findings are further evidence that the colonization of the mammary gland during lactation by immune system cells is the result of a selective homing process.

84. Least-Squares Time-Delay Estimation for Transient Signals in a Multipath Environment

Author

Abstract

The problem of estimating the arrival times of overlapping ocean- acoustic signals from a noisy received waveform that consists of scaled and delayed replicas of a deterministic transient signal is considered. It is assumed that the transmitted signal and the number of paths in the multipath environment are known, and an algorithm is developed that gives least-squares estimates of the amplitude and time delay of each path. A method is given to ensure that the global minimum of the error surface is found in spite of the existence of numerous local minima. The algorithm is then extended to the case in which the transmitted signal is not known precisely, but is assumed to belong to a parametric class of signals. The extended algorithm additionally obtains the parameters that characterize the transmitted signal. The algorithm is demonstrated on the class of signals consisting of gated sinusoids, using both simulated and experimental data....

Abstract

Consider the problem of estimating the arrival times of overlapping ocean-acoustic signals from a received signal which consists of an unknown deterministic signal along with scale and delayed versions due to multipath propagation plus additive noise. Our objective is to simultaneously determine the transmitted waveform and the arrival times. The proposed algorithm obtains approximately maximum liklihood estimates of the arrival times and the parameters which characterize the unknown signal. Our assumptions are that the number of different paths is known and that the signal must belong to a parametric class of signals. The algorithm is demonstrated on a class of signals consisting of gated sinusoids.
