Our results indicate new possibilities to manage yeast cellular resistance to dehydration by changing the bioavailability of calcium and magnesium ions. It is apparent that yeasts cultivated for dehydration would benefit from the control of magnesium and calcium bioavailabilities to improve dehydration–rehydration tolerance. Although we have described the influence of Mg2+ and Ca2+ ions only on short-term yeast viability, we may extrapolate these results to long-term storage. We therefore
anticipate that our findings can be exploited in the production and storage of stress-resistant preparations of active dry yeast. These results have shown that magnesium ion availability directly influenced yeast cells’ resistance to dehydration and, when additionally supplemented with calcium ions, this provided further significant benefits when cells were dehydrated. Gradual rehydration of dry yeast cells in water www.selleckchem.com/products/AZD6244.html vapour indicated that both magnesium and calcium may be very important for the stabilization of yeast cell membranes. In particular, calcium ions were shown to increase
resistance to yeast cell dehydration in stress-sensitive cultures from exponential growth phases. These results provide potentially new approaches to increase the stability/viability of yeasts during dehydration for example, in the production of active dry bakers’ and winemaking yeasts. In addition, we have shown that exponential-phase cells of S. cerevisiae can be successfully dehydrated Doxorubicin at high cell viabilities by paying special attention to metal ion availability. “
“A previous report identified the location of comparable architectonic areas in the ventral frontal cortex of the human and macaque brains [S. Mackey & M. Petrides (2010) Eur. J. Neurosci., 32, 1940–1950]. The present article provides greater detail with regard to the definition of architectonic areas within the ventromedial part of the human ventral frontal cortex and describes their location: (i) in Montreal Neurological Institute proportional stereotactic space; and (ii) in relation to
sulcal landmarks. old Structural magnetic resonance scans of four brains were obtained before the preparation of the histological specimens, so that the architectonic parcellation could be reconstructed in its original three-dimensional volume. The areal density of individual cortical layers was sampled quantitatively in the ventromedial prefrontal cortex of eight brains (16 hemispheres). The agranular cortex along the ventral edge of the corpus callosum and posterior margin of the ventromedial surface is replaced by a graded series of increasingly granular and more complexly laminated areas that succeed one another in a posterior-to-anterior direction. In parallel, the width of the supragranular layers (i.e. layers II and III) increases as compared with the infragranular layers (i.e.
