The data on visual thresholds for healthy human gingiva can be used as quality control tool/guide for selection and evaluation of dental materials, interpretation of color-related findings in clinical dentistry and research, and for standardization in dentistry. It is of particular value that this study was designed based on in-vivo color evaluation of healthy keratinized gingiva of subjects of different ethnicities, age groups, and gender.
Starvation for isoleucine inhibits chromosome, minichromosome and pBR322 DNA replication in a stringent strain of E. coli, but does not do so in a relaxed mutant. Starvation for other amino acids inhibits either chromosome and minichromosome replication in both strains. From these results we conclude that oriC and pBR322 replication are stringently regulated and that isoleucine seems not to be essential for the protein synthesis required at the initiation of oriC replication. Deprivation of isoleucine in a Rel~ strain gives rise to amplification of minichromosome and pBR322 with a better yield of the latter plasmid than that following treatment with chloramphenicol.
<p>Con Antonio Almagro Gorbea sobran las presentaciones. La sombra que proyecta su obra y reputación como arquitecto-restaurador, investigador y experto en arquitectura hispano-musulmana es muy alargada y sobradamente conocida y reconocida. Su proximidad a nuestra asociación nos permitió contactar con él en el pasado Congreso APEGA de Valencia, dónde le propusimos un encuentro en su lugar de trabajo para charlar de otros aspectos menos conocidos de la persona Antonio Almagro, en relación con su vocación restauradora, sus inicios profesionales, su paso por Roma como pensionado, su experiencia como docente, o sus nuevos proyectos desde la Escuela de Estudios Árabes de Granada del CSIC.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
