The rainbow trout (Oncorhynchus mykiss) model
of chemical carcinogenesis is becoming increasingly
important as a supplement to rodent studies. However,
much of the molecular biology of the carcinogenic
response is still unknown in the trout model. The ras
gene family has been implicated in the tumorigenesis of
both spontaneous and...
Christian communities vary widely in their degrees of acceptability or apprehensiveness toward newly developing technologies, ultimately aiming to help individuals optimally grow in their relationships to God and with others. Technologies viewed as conducive to accomplishing these goals are more likely to be accepted by Christian communities. Technologies viewed as...
Retinoic acid (RA) exerts important effects in the processes of vertebrate development, cellular growth and differentiation, and homeostasis. However, the mechanisms of action of RA in the control of cellular and developmental processes are incompletely understood, as the retinoid target genes have not been fully characterized. The goal of these...
Controversy regarding moral development research has given rise to a proliferation of theories competing for acceptance. For all these researchers, the work of Lawrence Kohlberg is the pivot point for comparisons, contrasts, and discussions. Still, no theories to date adequately describe and document a theoretically complete conception of moral judgment...
To characterize the mechanism through which myosin XI-K attaches to its principal endomembrane cargo, a yeast two-hybrid library of Arabidopsis thaliana cDNAs was screened using the myosin cargo binding domain as bait. This screen identified two previously uncharacterized transmembrane proteins (hereinafter myosin binding proteins or MyoB1/2) that share a myosin...
Using genetic approaches, particle image velocimetry and an inert tracer of cytoplasmic streaming, we have made a mechanistic connection between the motor proteins (myosins XI), cargo transported by these motors (distinct endomembrane compartment defined by membrane-anchored MyoB receptors) and the process of cytoplasmic streaming in plant cells. It is shown...
Low completion rates have created serious "leakage points" (Astin, 1988) and "severe hemorrhaging" (Lango, 1996) in higher education to a large number of Hispanics. Traditional research on college persistence, which has blamed the students' culture for low performance, is inaccurate. Little research has specifically investigated academic persistence from a cultural...
