New Onset Type 1 Diabetes Urine Metabolomics

Gas chromatography-mass spectrometry-based metabolomics to identify molecular signatures of Type 1 Diabetes (T1D) in urine. We utilize three cohorts in different stages post-diagnosis: (1) new onset, (2) within one year of diagnosis and (3) after 6 years of diagnosis. There were 91 metabolites identified in all three datasets with complete data represented in each cohort dataset. Cohort 1 (CNMC): 32 T1D cases; 32 healthy controls siblings Cohort 2 (BDCD): 27 T1D cases; 27 healthy controls siblings Cohort 3 (IUSOM): 12 T1D cases; 20 healthy controls Cases and controls matched on sex and age

Automated detection of bacteria in urine

A method for detecting the presence of bacteria in urine was developed which utilizes the bioluminescent reaction of adenosine triphosphate with luciferin and luciferase derived from the tails of fireflies. The method was derived from work on extraterrestrial life detection. A device was developed which completely automates the assay process.

Chemical pretreatment for the distillation of urine

Pretreatment of urine prevents micro-organism growth in boiler and kills micro-organisms in condenser. Chemicals also clean evaporation surface, fix ammonia in boiling chamber, and suppress foaming.
