Mycobacterium tuberculosis strains of Beijing genotype are rarely observed in tuberculosis patients in South America (2008)

Ritacco, V., López, B., Cafrune, P. I., Ferrazoli, L., Suffys, P. N., Candia, N., ...

The frequency of the Beijing genotype of Mycobacterium tuberculosis as a cause of tuberculosis (TB) in South America was determined by analyzing genotypes of strains isolated from patients that had...

Dust observations of Comet 9P/Tempel 1 at the time of the Deep Impact (2007)

Tozzi, G. P., Boehnhardt, H., Kolokolova, L., Bonev, T., Pompei, E., Bagnulo, S., ...

On 4 July 2005 at 05:52 UT, the impactor of NASA's Deep Impact (DI) mission crashed into comet 9P/Tempel 1 with a velocity of about 10 km/s. The material ejected by the impact expanded into the...

Broad- and narrowband visible imaging of comet 9P/Tempel 1 at ESO around the time of the Deep Impact event (2007)

Boehnhardt, H., Pompei, E., Tozzi, G., Hainaut, O., Ageorges, N., Bagnulo, S., ...

Context.On 4 July 2005 at 05:52UT the impactor of NASA's DeepImpact (DI) mission exploded at comet 9P/Tempel 1. The ejecta material of the impact expanded into the coma that is produced by normal...

Identification and analysis of functional elements in 1% of the human genome by the ENCODE pilot project (2007)

Birney, E, Stamatoyannopoulos, JA, Dutta, A, Guigo, R, Gingeras, TR, Margulies, EH, ...

We report the generation and analysis of functional data from multiple, diverse experiments performed on a targeted 1% of the human genomeas part of the pilot phase of the ENCODE Project. These data...

Worldwide emergence of extensively drug-resistant tuberculosis (2007)

Shah, N. S., Wright, A., Bai, G. H., Barrera, L., Boulahbal, F., Mart¡n-Casabona, N., ...

Mycobacterium tuberculosis strains that are resistant to an increasing number of second-line drugs used to treat multidrug-resistant tuberculosis (MDR TB) are becoming a threat to public health...

Deep impact: observations from a worldwide Earth-based campaign (2005)

Meech, K.J., Ageorges, N., A'Hearn, M.F., Arpigny, C., Ates, A., Aycock, J., ...

On 4 July 2005, many observatories around the world and in space observed the collision of Deep Impact with comet 9P/Tempel 1 or its aftermath. This was an unprecedented coordinated observational...
