| macromolecular crowding fails to fold a globular protein in cells. | proteins perform their functions in cells where macromolecular solutes reach concentrations of >300 g/l and occupy >30% of the volume. the volume excluded by these macromolecules stabilizes globular proteins because the native state occupies less space than the denatured state. theory predicts that crowding can increase the ratio of folded to unfolded protein by a factor of 100, amounting to 3 kcal/mol of stabilization at room temperature. we tested the idea that volume exclusion dominates the c ... | 2011 | 21534566 |
| analyses of recombinant stereotypic ighv3-21-encoded antibodies expressed in chronic lymphocytic leukemia. | chronic lymphocytic leukemia (cll) cells that use igh encoded by ighv3-21 and that have a particular stereotypic third cdr (hcdr3), dangmdv (motif-1), almost invariably express ig l chains (igl) encoded by iglv3-21, whereas cll that use ighv3-21-encoded igh with another stereotypic hcdr3, dpsfyssswtlfdy (motif-2), invariably express κ-igl encoded by igkv3-20. this nonstochastic pairing could reflect steric factors that preclude these igh from pairing with other igl or selection for an ig with a ... | 2011 | 21525382 |

| antibiotic susceptibility of cocultures in polymicrobial infections such as peri-implantitis or periodontitis: an in vitro model. | background: although polymicrobial infections, such as peri-implantitis or periodontitis, were postulated in the literature to be caused by synergistic effects of bacteria, these effects remain unclear looking at antibiotic susceptibility. the aim of this study is to compare the antibiotic susceptibilities of pure cultures and definite cocultures. methods: laboratory strains of aggregatibacter actinomycetemcomitans (aa) (previously actinobacillus actinomycetemcomitans), capnocytophaga ochracea ( ... | 2011 | 21405933 |
| tongue biofilm areal density and tongue coating index. | two methods have been employed to measure the amount of tongue biofilm in humans: (1) areal density of microbes (cfu cm(-2)) (tongue scrape from a known/measured area), or (2) a tongue-coating index, where a human judge assesses the amount of 'coating' by visual inspection. the two methods were compared, both on human volunteers and on artificial biofilms. fusobacterium nucleatum (fn), prevotella intermedia (pi), streptococcus mutans (sm) and peptostreptococcus micros (pm) were obtained from sto ... | 2008 | 21386152 |

| comparative evaluation of bactericidal potential of four root canal filling materials against microflora of infected non-vital primary teeth. | since complete debridement of the root canals of the primary teeth is not practically possible due to the highly variable root canal anatomy, success of the endodontic therapy depends partly on the use ofantibacterial irrigating agents and root canal filling materials. recent literature indicates that anaerobes comprise a majority of the bacteria in necrotic root canals ofprimary teeth. the study determined the antibacterial effectiveness of four root canal filling materials namely calcium hydro ... | 2010 | 21189760 |
