Solid character of membrane ceramides: a surface rheology study of their mixtures with sphingomyelin
Catapano ER Arriaga LR Espinosa G Monroy F Langevin D López-Montero I 《Biophysical journal》2011,(11):2721-2730
The compression and shear viscoelasticities of egg-ceramide and its mixtures with sphingomyelin were investigated using oscillatory surface rheology performed on Langmuir monolayers. We found high values for the compression and shear moduli for ceramide, compatible with a solid-state membrane, and extremely high surface viscosities when compared to typical fluid lipids. A fluidlike rheological behavior was found for sphingomyelin. Lateral mobilities, measured from particle tracking experiments, were correlated with the monolayer viscosities through the usual hydrodynamic relationships. In conclusion, ceramide increases the solid character of sphingomyelin-based membranes and decreases their fluidity, thus drastically decreasing the lateral mobilities of embedded objects. This mechanical behavior may involve important physiological consequences in biological membranes containing ceramides. 相似文献

Yeasts isolated from must before and during fermentation at a wine cellar of La Mancha region in Spain were characterised using Polymerase Chain Reaction / Restriction Fragments Lengths Polymorphism and Polymerase Chain Reaction / Temporal Temperature Gradient Gel Electrophoresis. S. cerevisiae strains were differentiated using mtDNA restriction analysis. Direct PCR-TTGE was also used to study biodiversity during wine fermentation, and revealed the variations in the population. It was observed that isolation by conventional plating may afford a skewed view of the strains taking part in wine fermentation. 相似文献

The relationship between body size (hind tibia length), <12 h egg load, wing wear and parasitoid age was used to estimate realised lifetime parasitism of recently dead Gonatocerus ashmeadi collected in a citrus orchard. Under prevailing field conditions and methodology assumptions, it was estimated that female G. ashmeadi lived on average for 183 ± 17 degree-days, parasitised a total of 87 ± 9 Homalodisca vitripennis eggs, and died with 34 ± 5 eggs remaining in the ovaries. Only 17% of dead G. ashmeadi died with no mature eggs suggesting that 83% of G. ashmeadi were not egg limited at time of death. Estimates of realised lifetime parasitism for female G. ashmeadi under prevailing field conditions in July and August in a southern California citrus orchard indicated that time of year had a significant effect on reproductive output. Additionally, live G. ashmeadi captured daily during June through August 2006 had body size, egg load and wing wear recorded to detect possible monthly changes in parasitoid age and egg load. Foraging G. ashmeadi captured alive in June were older and oviposited more eggs in the field compared with August. Only 0.5% of live G. ashmeadi were captured with no mature eggs in their ovaries indicating that the vast majority of live G. ashmeadi were not egg limited. 相似文献
