This means limiting the amount of accidents that can occur and reducing the intensity of those that do happen. Traffic signals can do this by adjusting speed limits and other traffic regulations to reflect the needs of a particular location. For example, a shift toward more bike lanes may nece...
The consumption of nuts does not result in a higher body weight; possible energy regulatory mechanisms include a decrease in subsequent energy intake and an increase in energy expenditure. This research aimed to explore how tree nut and peanut consumption affected energy intake, compensation, and exp...
Ceramide, the precursor of all complex sphingolipids, is a potent signaling molecule that mediates key events of cellular pathophysiology. In the nervous system, the sphingolipid metabolism has an important impact. Neurons are polarized cells and their normal functions, such as neuronal connectivity and...
Furthermore, since pollinators have only one opportunity to enter a fig (either a true fig wasp nursery in male trees or a fatally attractive deceptive one in female trees), the question of directed pollinator movement from one sex to another by sexual dimorphism in floral scent also does ...
1). The amino-terminal helix forms a coiled-coil with the α-helix of Gβ, whereas the carboxyl-terminal helix makes extensive contacts with the base of the Gβ propeller. Unlike Gα, the Gβγ dimer does not appear to change conformation upon dissociation from the heterotrimer (16). ...
so the protons in one layer of water that bond to oxygen in an adjacent layer is no longer possible and this will not allow an ice like rigid structure, but it does allow a liquid crystalline state to manifest. This is why liquid EZ is a fluid because it cannot have a rigid structure...
Although soaking experiments were not able to detect a metal ion at this site in the Schistosome hammerhead crystal structure (Martick and Scott 2006), it is likely that a magnesium ion does occupy this site under physiological conditions. Phosphorothiotes at either P9 or P1.1 in the ...
Moreover, the pH of the system may shift when additives are included such as a biocide, which is commonly added to retard growth of fungi and the like. Although the stability of the water-containing emulsions can be enhanced to some extent by refrigerating them, or the problem of reduced ...
The catabolism of ceramide takes place in lysosomes from where sphingosine can be released [95] in contrast to ceramide, which does not appear to leave the lysosome [96]. Free sphingosine is probably trapped at the ER-associated membranes where it undergoes re-acylation (condensation with a ...
The generation of CFC from primitive progenitors is induced by cytokines and does not require GAGs A 2-fold expansion in the numbers of CFC generated was sustained for 2 to 5 weeks in cultures supplemented with IL-3 + MIP-1α (Figure4). The addition of HS to IL-3 + MIP-1α did not...
