Mammotrophic Potency of Human Urine

Metastasis in a transplantable mammotrophic pituitary tumor.

Two strains of a mammotrophic pituitary tumor were compared; the secretion of adrenocorticotropic hormone had declined appreciably in one and, in the other, was un changed. The secretion of adrenocorticotropic hormone by the pituitary tumor does not appear to be related to the capacity for metastasis inasmuch as metastasis was ob served in the retroperitoneal lymph nodes of animals bearing both...

Antibacterial activity of human urine.

The fate of bacteria in human urine was studied after inoculation of small numbers of Escherichia coli and other bacterial strains commonly implicated in urinary tract infection. Urine from normal individuals was often inhibitory and sometimes bactericidal for growth of these organisms. Antibacterial activity of urine was not related to lack of nutrient material as addition of broth did not dec...

Application of Ion Mobility Spectrometry for Determination of Morphine in Human Urine

In this study, a rapid, simple and sensitive ion mobility spectrometry (IMS) method with corona discharge as ionization source was described for the morphine determination in human urine. Morphine was extracted and purified from urine samples using solid phase extraction procedure with C18 column. It can offer the clean extracts which no extra peaks were observed in IMS. Under operating experim...

The Human Urine Metabolome

Urine has long been a "favored" biofluid among metabolomics researchers. It is sterile, easy-to-obtain in large volumes, largely free from interfering proteins or lipids and chemically complex. However, this chemical complexity has also made urine a particularly difficult substrate to fully understand. As a biological waste material, urine typically contains metabolic breakdown products from a ...
