What is Bile Acid? Bile acids are the main components of bile and are synthesized in the liver from cholesterol through a series of enzymatic reactions. Bile acids can be divided into free bile acids and conjugated bile acids according to their structures. Free bile acids include bile acids, goose deoxycholic acid, deoxycholic acid and lithophanic acid. The above free bile acids are combined ...
In the following study, we came up with and validated a prompt, sensitive and precise method for the simultaneous determination of 56 antimicrobial drugs (tetracyclines, sulfonamides, β-lactams, macrolides and quinolones) using the ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). This method was implemented with success to determine antibiotics in samples ...
The photolytic characteristics of benzothiostrobin were investigated in solution and on soil and glass surface. The main influence factors such as initial concentration, organic solvent and the aqueous environmental substances, including NO2–, NO3–, Fe2+, Fe3+, H2O2 and turbidity were investigated. Three photodegradation products of benzothiostrobin were identified by ultra-performance liquid ...

The selection and prioritization of pharmaceuticals and of their transformation products for evaluating effects on the environment and human health is a challenging task. Both compound‐ (e.g. mixture composition, concentrations) and biological‐ (e.g. relevant endpoint, biological organizational level) oriented approaches applied for tackling these issues often resemble a Lernaean hydra by ...
Tea is very important to them! If Waters Wilmslow ran out of tea it is likely the MS Research Team would struggle to function. The ancient Chinese Ruler, Emperor Jing Di, took tea to the grave with him for a cuppa in the afterlife. Many treasures were found in his tomb including; food, weapons, ceramic animals, and a full size chariot with horses. The discovery included several food items; rice ...
Occurrence and removal efficiency of six polycyclic aromatic hydrocarbons (PAHs) (fluoranthene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, benzo[ghi]perylene and indeno[1,2,3-cd]pyrene) in wastewater were monitored at different treatment processes in three wastewater treatment plants (WWTPs) by using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). ...
