Cytotoxic constituents of the terrestrial plant Bridelia ferruginea were isolated using bioactivity-guided fractionation, which revealed the presence of the previously known deoxypodophyllotoxin (1), isopicrodeoxypodophyllotoxin (2), β-peltatin (3),

An experiment with adult humans investigated the effects of response-contingent money loss (response-cost punishment) on monetary-reinforced responding. A yoked-control procedure was used to separate the effects on responding of the response-cost con

Anecdotal reports indicate that GHB produces subjective effects similar to those of ethanol. However, recent investigations comparing the discriminative stimulus effects of GHB to those of ethanol suggest that the subjective effects of these substanc

In the forming vertebrate heart, bone morphogenetic protein signaling induces expression of the early cardiac regulatory gene nkx-2.5. A similar regulatory interaction has been defined in Drosophila embryos where Dpp signaling mediated by the Smad ho

The T-box gene tbx5 is expressed in the developing heart, forelimb, eye, and liver in vertebrate embryos during critical stages of morphogenesis and patterning. In humans, mutations in the TBX5 gene have been associated with Holt–Oram syndrome, whi

nkx-2.5 is one of the first genes expressed in the developing heart of early stage vertebrate embryos. Cardiac expression of nkx-2.5 is maintained throughout development and nkx-2.5 also is expressed in the developing pharyngeal arches, spleen, thyro

The energy-budget rule is an optimal foraging model that predicts that choice should be risk averse when net gains plus reserves meet energy requirements (positive energy-budget conditions) and risk prone when net gains plus reserves fall below requi

The MR SAT design team at the University of Missouri–Rolla is in the process of developing a pair of microsatellites designed to demonstrate formation flight using low-cost, off-the-shelf technologies. As part of the demonstration, a newly develope
