Direct nano-electrospray ionization tandem mass spectrometry for the quantification and identification of metronidazole in its dosage form and human urine [PDF]
Royal Society Open Science, 2019 A rapid, sensitive and direct nano-electrospray ionization-tandem mass spectrometry (NS-ESI-MS/MS) method, using an offline nanospray (NS) capillary, has been developed and validated for the analysis of metronidazole (MTZ).

Antibacterial activity of human urine [PDF]
Journal of Clinical Investigation, 1968 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.

Hydroxylysine Glycosides in Human Urine
Clinical Chemistry, 1971 Abstract Hydroxylysyl-galactosyl-glucose (HGG) and hydroxylysyl-galactose (HG) were isolated from normal human urine and shown to be identical with hydroxylysine glycosides (OHLG's) whose structure had been elucidated in other laboratories.

Measurement of mercury in human urine [PDF]
Journal of Clinical Pathology, 1970 Four methods of determining the concentration of mercury in human urine have been studied. A simple method suitable for general laboratory use is recommended and the requirements for accurate results are defined. The method employs mild oxidation with permanganate and HS 2 O

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
