Research on chemicals used as pesticides has been intensified
because of current interest in the possible long range effects on the
biota. It is vitally important to understand the action of these
chemicals on the metabolism of animals and plants which have
direct or indirect contact with pesticides.
It has...
In an attempt to find a laboratory species which develops an
experimental myopathy similar to white muscle disease (WMD) in
lambs, comparative studies of nutritional muscular dystrophy of
chicks were initiated. This condition was grossly visible as white
striations running parallel with the fibers of the pectoral muscles and
was...
Although 4- and 5-diacetamidopyrimidines have been reported
in the literature within the past eleven years, it was not until 1965
that a 2-diacetamidopyrimidine was reported. The current investigation
was undertaken to determine whether other 2-diacetamidopyrimi-dines could be synthesized and what the effect of various nuclear substituents would be on the...
Dihalocarbenes have been generated mainly by thermal decomposition
of sodium trihaloacetate and phenyl (trihalomethyl)mercury,
and give gem-dihalocyclopropyl adducts with various steroid olefins.
A new procedure involving the use of sealed tubes makes possible the
addition of dihalocarbenes to sterically hindered olefins. In this manner,
7-cholestenyl benzoate when treated with PhHgCC1₃...
