Diet composition is associated with endogenous formation of N-nitroso compounds in obese men

submitted by: silviagratz
Endogenous formation of carcinogenic N-nitroso compounds (NOC) occurs in the human gut. Red meat is considered the most important dietary component linked to NOC formation, although nitrate and vitamin C (VitC) also contribute. We previously showed that high-protein weight-loss diets increased fecal NOC and this was enhanced by simultaneous carbohydrate restriction. Although previous studies have focused on the effect of either 1 or 2 dietary components on endogenous NOC formation, no...

Rocket Evaporator

submitted by: Chrom Solutions
The Rocket™ Evaporator is a revolutionary solvent evaporator for use in laboratories seeking to spend minimal time and effort to process multiple samples for analysis. Concentration and evaporation is an important step in achieving accurate analytical results with sample extracts.The Rocket Evaporator automates this process, allowing the analyst to spend more time on other projects. The Rocket Evaporator can be used either to dry samples completely, or to concentrate them to a small...

Separation of Carbohydrates in Pharma & Food Products (Webinar)

submitted by: Chrom Solutions
This webinar highlights the use of high-performance anion-exchange chromatography with Pulsed Amperometric Detection (HPAE-PAD) for the analysis of carbohydrates including mono-, di- and oligo- saccharides. The experts also discuss how this approach is used to characterize large polysaccharies, such as maltodextrin. Focusing on pharmaceutical, biopharmaceutical, and food & beverage matrices, this webinar is of value to anyone looking for a fast, easy and economical way to detect multiple...
