The Action of Whole Blood upon Acids

Purification of nucleic acids from whole blood using isotachophoresis.

We present and demonstrate a novel technique for the purification of nucleic acids from biological samples using isotachophoresis (ITP). We demonstrate a simple and rapid method to achieve ITP-based extraction, preconcentration, and purification of DNA from nanoliter volumes of whole blood. We show that ITP purification yields genomic DNA samples which can be quantitated with fluorescence measu...

Observations upon the Action of Salts on the Catalase of the Blood in Rabbits

Bicarbonate of soda fed in varying quantities over a period of months has no direct effect upon the catalytic activity of the blood. When fed to rabbits, it invariably causes a slight albuminuria and occasional casts. The kidneys of pregnant animals, especially in the later stages of pregnancy, seem to be more susceptible to this salt, and in some instances there may be complete suppression of ...

The Action of Glandular Extracts Upon

The uterine tissue consists of unstriped muscle fibre and ganglia of the sympathetic system imbedded in it. The sacral roots and pelvic nerve do not enter into the composition of the uterine plexus. In the rabbit, irritation of the hypogastric nerve produces vasoconstriction and contraction of the uterus. In cats, stimulation of the hypogastric nerve produces at one time contraction and at othe...
