Effect of Enological Practices on the Resveratrol Isomer Content of Wine
Resveratrol (trans-3,5,4'-trihydroxystilbene) is a phytoalexin produced by grapevines in response to fungal infection, particularly to Botrytis cinerea, the causal organism for gray mold. ThisExpand
Mediation of elicitin activity on tobacco is assumed by elicitin-sterol complexes.
The binding kinetics of elicitins are related to their biological effects, which constitutes the first evidence that binding sites could be the biological receptors. Expand
Analysis of resveratrol in Burgundy wines
Recent studies have shown that resveratrol (3,5,4'‐trihydroxystilbene), a phytoalexin related to grape disease resistance, could occur in American and Bordeaux wines. It was also suggested thatExpand
A lipid transfer protein binds to a receptor involved in the control of plant defence responses
Binding and in vivo competition experiments point out that these binding sites are common to LTP1 and elicitins and confirm that they are the biological receptors of elicitins. Expand
Elicitins trap and transfer sterols from micelles, liposomes and plant plasma membranes.
Using elicitins, proteins secreted by some phytopathogenic Oomycetes (Phytophthora) known to be able to transfer sterols between phospholipid vesicles, the transfer of sterols between micelles,Expand
Fatty acids bind to the fungal elicitor cryptogein and compete with sterols
It is reported that cryptogein binds fatty acids, and it is shown that C7 to C12 saturated and C16 to C22 unsaturated fatty acids are the best ligands. Expand
Gas Chromatographic and Mass Spectrometric Study of Trimethylsilyl Ethers of Cardiac Aglycones
Abstract Cardenolides may be converted to volatile derivatives by silylation. Three levels of silylation have been defined. The use of HMDS-TMCS leads to TMSi ether formation for all relativelyExpand
Assessment of serum cholesterol by two methods: gas-liquid chromatography on a capillary column and chemical ionization-mass fragmentography with isotopic dilution of [3,4-13C] cholesterol as
A gas-liquid chromatographic (GLC) method and an isotopic dilution-mass fragmentographic (ID-MF) procedure using the same capillary chromatographic separation are described for serum cholesterolExpand
Induction of corticosteroid biosynthetic pathway by ACTH and high-density lipoprotein in newborn rat adrenocortical cells cultured in serum-free medium.
The results suggest that HDL is at least partly internalized and that probably its constituents contribute greatly to the control of the two different steroidogenic pathways. Expand
Docosahexaenoic acid modulates phorbol ester-induced activation of extracellular signal-regulated kinases 1 and 2 in NIH/3T3 cells
It is shown for the first time that DHA inhibits MAP kinase (ERK1/ERK2) activation and proliferation of NIH/3T3 cells via its inhibitory action on PKCα and ε isoforms. Expand
