Sarcosine oxidase activity of rat liver tissue: Effect of folic acid deficiency and induced hyperthyroidism
(Elsevier, 1952-11)
The sarcosine oxidase content of hepatic tissue from rats made deficient in folic acid was similar to that of normal rats. This is taken as evidence that sarcosine oxidase activity is not dependent upon the presence of ...
Reduktion von Aminosäuren zu Aminoalkoholen mittels Lithiumaluminiumhydrid
(Springer-Verlag, 1953-11)
Durch Umsetzung mit Lithiumaluminiumhydrid in Tetrahydrofuran wurde eine Anzahl freier Aminosäuren zu den entsprechenden Aminoalkoholen reduziert. Der Anwendungsbereich der Methode wird an Hand von Beispielen erläutert.
A method for the determination of the electrophoretic patterns of hemolyzed mouse sera
(Elsevier, 1951-05)
A method is presented that will give comparable results for the evaluation of electrophoretic data on hemolyzed mouse serum patterns. Not only may hemoglobin be determined in the serum, but its contribution to the total ...
Factors influencing xanthine oxidase activity in rat skin
(Elsevier, 1955-05)
1. 1. A method is described for preparing skin extracts which show reasonably consistent xanthine oxidase activities.2. 2. Levels of xanthine oxidase in skin do not change significantly during the first 21 days after birth. ...
Quantitative semimicro inorganic procedures
(Elsevier, 1951)
Representative volumetric, gravimetric, and electrolytic determinations, many on "practical" samples of alloys or minerals, have been applied on a semimicro level. The use of classical microchemical apparatus, which is ...
Polarographic reduction of uranium(VI) under complexing and noncomplexing conditions nature of the uranium(V) sulphate complex
(Elsevier, 1959-10)
The polarographic reduction of U(VI) to U(V) in acid solution is sensitive to both type and concentration of anion present. Consequently, the reduction was studied using perchlorate as a non-complexing anion and sulphate ...
Versuche zur Synthese des Cytisins. Dehydrierung von Tetrahydro-cytisin zu Cytisin
(Springer-Verlag, 1954-09)
Die Dehydrierung von Tetrahydro-cytisin zu Cytisin mit Palladium verläuft glatt, wenn man die Iminogruppe durch Acetylierung schützt. Durch Erhitzen des N-Acetyl-tetrahydrocytisins mit Pd-Mohr bei 280° erhält man so in ...
