(1964)The rate of the rise of diastolic blood-pressure with age increases significantly in the inhabitants of Easter Island when they migrate to the South American continent. Consequently, essential hypertension (which is ...
-
(1964)Red cell survival was studied by radioactive chromium technique in 15 cases of hepatitis, 13 of cirrhosis of the liver, and 6 of extrahepatic obstructive jaundice. All patients but 2 with hepatitis and 1 with cirrhosis had ...
-
(1964)It is shown that an elementary particle of conventional field theory may, under certain conditions, lie on a Regge trajectory. These conditions are that the system contain a "nonsense" channel at the angular momentum of ...
-
(1964)The aminoacyl-RNA synthetases have been shown to carry out the following two-step reaction: 1. 1) amino acid + ATP + enzyme ⇌ aminoacyl-AMP-enzyme + PPi 2. 2) aminoacyl-AMP-enzyme + sRNA ⇌ aminoacyl-sRNA + AMP + enzyme. ...
-
(1965)The effect of DDT and DDE, a DDT-non toxic analog, on protein biosynthesis in Triatoma infestans nymphs and adult specimens has been studied. DDT increases the in vivo rate of incorporation of dl-leucine-1-C14 into total ...

Sodium transport inhibition by selective mitochondrial inhibitors in the urinary bladder of the toad (1966)The effects of selective mitochondrial inhibitors on the short‐circuit current and oxygen consumption displayed by the isolated urinary bladder of the toad was studied. Three types of compounds were used: (a) electron ...
