| [results of treatment of deep neck abscesses and phlegmons]. | neck, as a structure very closely connected with oral cavity and pharynx, with great number of lymph nodes, (about 2, 3 of all are in the neck), is sometimes a localization of purulent inflammatory process but its incidence is not so high as the incidence of inflammations of surrounding organs and tissue. deep neck abscesses are localized under the upper fascial layer. they have a serious clinical picture which could be further complicated if inflammation spreads on vessels or neck organs. if th ... | 1999 | 10624393 |
| robustness of protein folding kinetics to surface hydrophobic substitutions. | we use both combinatorial and site-directed mutagenesis to explore the consequences of surface hydrophobic substitutions for the folding of two small single domain proteins, the src sh3 domain, and the igg binding domain of peptostreptococcal protein l. we find that in almost every case, destabilizing surface hydrophobic substitutions have much larger effects on the rate of unfolding than on the rate of folding, suggesting that nonnative hydrophobic interactions do not significantly interfere wi ... | 1999 | 10631990 |
