The association between staphylococcal enterotoxin (SE) B and toxic shock syndrome (TSS) toxin 1 (TSST-1) in menstrual and nonmenstrual TSS was examined. Production of SEB and TSST-1 in the culture supernatants from 344 Staphylococcus aureus isolates was quantitated by noncompetitive ELISA (lower detection limit, 0.5 ng/mL for both assays). In the ELISA for(More)
This study focuses on three main goals: First, 3-year-olds' spatial assembly skills are probed using interlocking block constructions (N = 102). A detailed scoring scheme provides insight into early spatial processing and offers information beyond a basic accuracy score. Second, the relation of spatial assembly to early mathematical skills was evaluated.(More)
We present a family of trigonal pyramidal iron(II) complexes supported by tris(pyrrolyl-α-methyl)amine ligands of the general formula [M(solv)(n)][(tpa(R))Fe] (M = Na, R = tert-butyl (1), phenyl (4); M = K, R = mesityl (2), 2,4,6-triisopropylphenyl (3), 2,6-difluorophenyl (5)) and their characterization by X-ray crystallography, Mössbauer spectroscopy, and(More)
Although scientific knowledge in viral oncology has exploded in the 20th century, the role of bacteria as mediators of oncogenesis has been less well elucidated. Understanding bacterial carcinogenesis has become increasingly important as a possible means of cancer prevention. This review summarizes clinical, epidemiological, and experimental evidence as(More)
BACKGROUND Helicobacter pylori vaccines are under development to prevent infection. We quantified the cost-effectiveness of such a vaccine in the United States, using a dynamic transmission model. METHODS We compartmentalized the population by age, infection status, and clinical disease state and measured effectiveness in quality-adjusted life years(More)
Highly purified staphylococcal toxic shock syndrome toxin 1 (TSST-1) was tested for its ability to induce the cytokines tumor necrosis factor (TNF) and interleukin-1 (IL-1) from fractionated human peripheral blood mononuclear cells prepared from seven healthy donors. Highly purified monocytes alone or T lymphocytes alone did not produce TNF or IL-1 when(More)
Beginning in 2005, the Centers for Disease Control and Prevention (CDC) expanded the overseas presumptive treatment of intestinal parasites with albendazole to include refugees from the Middle East. We surveyed the prevalence of helminths and protozoa in recent Middle Eastern refugees (2008-2010) in comparison with refugees from other geographical regions(More)
BACKGROUND Helicobacter pylori can cause hypochlorhydria in some hosts and predispose to diarrheal infections. AIMS We tested the hypothesis that chronic H. pylori infection increases the risk of diarrheal illness due to an acid-sensitive organism: enteropathogenic Escherichia coli (EPEC). METHODS After testing healthy adult volunteers for H. pylori, 19(More)
This half-day IDC 2015 workshop focuses on children's curiosity and how novel digital technologies can help assess and promote it. Our goal is to explore the design, development, use and evaluation of new technologies for this purpose, in terms of: i) challenges in assessing children's curiosity; ii) different evaluation methodologies; iii) design(More)
