Several tick sampling methods were evaluated for ixodes scapularis Say and Amblyomma americanum (I.) in oak-dominated mixed hard-wood, pitch pine-dominated, and mixed hardwood and pine forests in coastal New Jersey. Walking surveys were more efficient for collecting I. scapularis adults than dragging by a factor of > 2:1. In contrast, drag sampling yielded(More)
The staphylococcal superantigen toxic shock syndrome toxin 1 (TSST-1) induces massive cytokine production, which is believed to be the key factor in the pathogenesis of TSS. The temporal sequence and kinetics of both proinflammatory and anti-inflammatory cytokines induced by TSST-1 in human peripheral blood mononuclear cells were investigated. A panel of(More)
A single barrier application of granular deltamethrin to the woodland edges of a forested residential community in late spring significantly reduced the abundance of Ixodes scapularis Say nymphs. The application also suppressed the population of Amblyomma americanum (L.) nymphs, which recently became established in the study area. The efficacy of(More)
CONTEXT Fatigue is the most common sequela among non-small cell lung cancer (NSCLC) survivors one to six years post-treatment and is associated with functional limitations. OBJECTIVES This study examined the prevalence, severity, and correlates of fatigue among early stage NSCLC survivors. METHODS Three-hundred fifty individuals diagnosed and surgically(More)
We evaluated the effects of a single application of granular carbaryl made against nymphal Ixodes scapularis Say on the diversity and abundance of forest arthropods taken in pitfall traps in oak and mixed oak-pine forest sites for 12 wk after treatment in central New Jersey. Significant short-term changes in arthropod assemblages were detected immediately(More)
Hunterdon Country, New Jersey, experienced a significant increase in the number of Lyme disease cases during 1990-1995, accounting for 21.2% of all New Jersey cases. This study compares the relative abundance of Ixodes scapularis Say in similar habitats in Hunterdon County, an emerging Lyme disease area, and Monmouth County, where Lyme disease has been(More)
The diurnal questing behavior of adult Ixodes scapularis Say and Amblyomma americanum (L.) were monitored in the field to determine whether ticks would be collected with greater frequency during certain times of the day and under certain ambient meteorological conditions. Temperature and relative humidity explained a significant amount of the total(More)
OBJECTIVE To review the current state of knowledge of apoptosis, with an emphasis on identifying potential and established roles for apoptosis in the pathogenesis of infectious diseases. DATA SOURCES MEDLINE and the University of British Columbia library system were searched using the search subject, "apoptosis", for the years 1992 to 1996. Further search(More)
Removal of leaf litter in wooded areas of a forested residential community significantly reduced the abundance of questing blacklegged tick, Ixodes scapularis Say, nymphs throughout their peak activity period. Removal of leaf litter, using hand rakes and leaf blowers during the early spring (March) and early summer (June) resulted in reductions in nymphal(More)
