- ... The FIV-infected cat is a small animal model for HIV mother-to-child transmission (MTCT) because the two lentiviruses are biologically related and produce similar clinical syndromes. Both viruses are vertically transmissible and may negatively impact reproductive outcome. Maternal hematological and virological parameters are predictors of MTCT in HIV-infected women. Our purpose was to determine wh ...

- ... Escalating energy and fertilizer N prices have renewed farmer interests in methods that reduce manure management costs and enhance the fertilizer value of manure. At the same time, air quality legislation seeks to mitigate ammonia loss from animal operations. We compared two dairy heifer management practices on manure N capture and recycling through crops: the conventional practice of barn manure ...

- ... Biosolids land application applies varying trace metal amounts to soils. Measuring total soil metals is typically performed to ensure environmental protection, yet this technique does not quantify which soil phases play important metal release or attenuation roles. We assessed the distribution of biosolids-borne Cu and Zn associated with soluble/exchangeable, specifically adsorbed/carbonate-bound, ...
