Superwarfarins are anticoagulant rodenticides that are 100 times more potent and 15 times more persistent than warfarin. They have been used since the 1980s and cause over 10,000 cases of accidental and intentional poisonings per year. Apart from inducing uncontrollable bleeding, by inhibiting the vitamin K cycle, superwarfarins can disrupt...
The loss of all deuterium labels from previous feedings of [2-²H]-,
[3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy
of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the
biosynthesis of the streptolidine portion of streptothricin F (la).
In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]-
arginine (32) was...
A marine seismic refraction study, conducted in August 1976 by personnel
from Oregon State University and the University of Connecticut between Cape
Simpson and Prudhoe Bay, Alaska, provides data for analysis which yields a
subsurface structural and geological cross-section of the area.
The results suggest that the structural homocline which...
A cost reduction analysis is performed by coordinating
the exchange of LANDSAT (formerly ERTS) data between a CDC
3300 and a PDP8/L minicomputer. The LANDSAT data is displayed
on a 4002 Tektronix terminal by means of a grayscale output.
Large amounts of data and number manipulation are processed
in the...
This study deals with the autoradiographic analysis, using a
DNA precursor (tritiated thymidine), of the trophoblastic giant cells
in the placentae of the golden hamster (Mesocricetus auratus Waterhouse),
beginning with the sixth day of gestation and extending to term
on day sixteen. Both the percent of labelled cells in the...
