In predator-ungulate-plant systems, empirical research quantifying how predators affect ungulate group sizes and distribution, in the context of other influential variables, is particularly needed. The risk(More)
Murine cytotoxic T lymphocytes contain, in addition to the cytotoxic pore-forming protein perforin, another cytolytic factor localized in both cytoplasm and granules. Like perforin, this CTL cytotoxin lyses a variety of tumor cells; unlike perforin, it is stable in the presence of calcium, requires several hours to induce maximal lytic activity, and is(More)

Aberrant expression of the apoptosis inhibitor bcl-2 provides a survival advantage throughout oncogenesis and can facilitate chemotherapeutic resistance in a variety of human cancers. Follicular lymphoma (FL) for example, is characterized by the chromosomal translocation t(14;18), which results in bcl-2 overexpression and initiates lymphomagenesis. Although(More)
Data from a longitudinal study of 1342 Zambian children aged between 0 and 60 months are used to derive reference standards for mid-upper arm circumference. To determine the sensitivity, specificity, and predictive value of the arm circumference measurement as an indicator of nutritional status, associations between arm circumference and other(More)
