Chemical Composition of the Leaf Oil of from Vietnam
Natural Product Communications, 2014 Fresh leaves of Actephila excelsa (Dazl.) Muell. from Vietnam were steam distilled to produce an oil in a yield of 0.15% (v/w). The essential oil was analyzed by a combination of capillary gas chromatography-flame ionization detection (GC-FID) and gas ...

Capillary gas-liquid chromatography of glycine-conjugated bile acids without prior hydrolysis.
Journal of Lipid Research, 1986 A method is described for the gas-liquid chromatographic (GLC) analysis of intact glycine conjugates of the major bile acids present in human plasma. It is, therefore, now possible to analyze glycine-conjugated and unconjugated bile acids together on a ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

A mathematical model for capillary gas chromatography [PDF]
In the study of gas chromatography a model is presented to simulate a capillary gas chromatographic system. The model was developed to study the concentrations of sample gas as a function of time and space as it travels through the capillary column.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface
FEBS Open Bio, EarlyView.HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

FEBS Open Bio, EarlyView.The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Alkanes from plants of the genus achillea [PDF]
Journal of the Serbian Chemical Society, 1999 The hydrocarbon fractions of three species of Achillea L. have been analysed by capillary gas chromatography (GC) and GC-mass spectrometry(GC-MS) and were shown to consist of the conventional, odd-carbon number dominant distributions of n-alkane
