High-performance liquid chromatography (HPLC) and ultra-performance liquid chromatography (UPLC) are both commonly used techniques when it comes to separating components. Click to read more...
How to choose between HPLC or ultra-high-performance liquid chromatography (UHPLC) as they each have their own advantages and disadvantages
research scientists at Schering Plough Institute developed this new technique. The key difference between HPLC and fast HPLC lies upon the pump pressure that we use for the separation. That is; the pump pressure that we use for HPLC is around 40...
Thekey differencebetween natural and forced convection is thatin natural convection, the motion of the fluid is influenced by natural means whereas, in forced convection, the motion of fluids is influenced by external means.The difference between natural and forced convection related to heat transfer ...
In the present study, Cyp-null mice were used to determine which CYPs are responsible for the differences in production of bile acid metabolites between humans and mice, notably the hepatic synthesis of MCA. Individual bile acid concentrations were determined in wild-type and Cyp-null mice leading...
Wogonin (WO) and its glucuronide, wogonoside (WG) exhibit various beneficial bioactivities that may have potential for the development of novel drugs. In this study, we determined their pharmacokinetic characteristics in rats after intragastric administration of WO and intraportal vein injection of WG....
Most studies have focused on the combined toxicity effects of insecticide mixtures. However, the interaction between the insecticide mixtures and their environmental behaviors is also important for controlling residue risks. It is necessary to understand the transformation in the agro-food chain and the...
The mean air temperature and UV intensity on a sunny day during the apple peel color transition period in both orchards are shown in Figure S1. Both orchards have 5-year-old trees planted between and within row distances of 3.5 and 1.5 m, respectively, and grafted onto M26 interstock. ...
