Existing classification schemes and thesauri are lacking in well-defined semantics and structural consistency. Empowering end users in searching collections of ever increasing magnitudes with performance far exceeding plain free-text searching (as used in many Web search engines), and developing systems that not only find but also process information for(More)
This article explores the characteristics of a newly emergent 'neuroculture' and its relationship to cultures of ageing; in particular, the social meanings associated with 'active ageing' and 'cognitive health' and the discourses and sciences around memory and the 'ageing brain'. The argument proposes a critical perspective on this relationship by looking(More)
The ability of in vitro grown Leishmania promastigotes to resist lysis by complement and survive in undiluted human serum was related to the species of Leishmania and the growth phase in culture. Promastigotes from log phase cultures were always killed in undiluted serum, whereas survival of stationary phase promastigotes varied among species. All L. major(More)
This report outlines a proposed metadata framework for resource discovery of agricultural resources, and in particular to describe information resources in agricultural sciences. The overall work is the result of a collaborative effort between a number of partners in the agricultural community and the Library and Documentation Systems Division of FAO. The(More)
The lexical decision (LD) and naming (NAM) tasks are ubiquitous paradigms that employ printed word identification. They are major tools for investigating how factors like morphology, semantic information, lexical neighborhood and others affect identification. Although use of the tasks is widespread, there has been little research into how performance in LD(More)
Very little is known about renal failure and renal replacement therapy in patients with Down syndrome (DS) [1]. We would like to report our experience with a pediatric patient with DS who developed end-stage renal failure secondary to hemolytic-uremic syndrome, and has been treated successfully with continuous cycling peritoneal dialysis (PD) for more than(More)
Nonspecific immunoregulatory events were examined in inbred jirds chronically infected with Brugia pahangi. The responsiveness of spleen cells from infected animals to the T cell mitogens PHA and Con A and to the B cell mitogens, LPS and PWM, was found to be suppressed by as much as 90% when compared with the reactivity of lymphocytes from normal animals.(More)
This is a report of a case of massive cutaneous larva migrans in a 20-year-old man who also had pulmonary symptoms and larval invasion of the skeletal muscles. In sections of a muscle biopsy specimen taken 3 months after the initial cutaneous lesions, a third-stage Ancylostoma larva, probably A. caninum, was found within a muscle fiber.
In studies conducted between 1984 and 1986, the vector competency of Culex quinquefasciatus was assessed after bloodfeeding on 61 Haitian volunteers with different densities of Wuchereria bancrofti microfilariae (mf) and on 11 that were amicrofilaremic. Infected volunteers included persons previously given diethylcarbamazine citrate for 12 consecutive days(More)
Chronic B. pahangi infection (greater than or equal to 5 mo) in the jird, Meriones unguiculatus, leads to the induction of adherent nonspecific suppressor cells that are capable of modulating the in vitro mitogen responsiveness of spleen cells. In the present studies, a correlation between suppression of mitogen responsiveness and lack of reactivity to B.(More)
