El poeta antioqueño Porfirio Barba Jacob se hizo periodista en México donde desempeñó como reportero, dejando evidencias magistrales de varios sus cubrimientos. Desde un enfoque biográfico indago la destreza del empírico, formado experiencia las calles, para integrar su trabajo periodístico con producción poética. Estudio figura Dama, motivo poema “La Dama cabellos ardientes”, que hace una mist...

The status of dark matter search in Heidelberg is reviewed. After one year of running the HDMS prototype experiment in the Gran Sasso Underground Laboratory, the inner crystal of the detector has been replaced with a HPGe crystal of enriched Ge. The results of the operation of the HDMS prototype detector are discussed. In the light of the contradictive results from the CDMS and DAMA experiments...

Dissociable antibody microarray (DAMA) staining is a technology that combines protein microarrays with traditional immunostaining techniques. It can simultaneously determine the expression and subcellular location of hundreds of proteins in cultured cells and tissue samples. We developed this technology and demonstrated its application in identifying potential biomarkers for breast cancer. We c...

The IGEX Collaboration enriched Ge double-beta decay detectors are currently operating in the Canfranc Underground Laboratory with an overburden of 2450 m.w.e. A recent upgrade has made it possible to use them in a search for WIMPs. A new exclusion plot, σ(m), has been derived for WIMP-nucleon spin-independent interaction. To obtain this result, 30 days of data from one IGEX detector, which has...

The phenomenon of syntenic genetic conservation of chromosomes enables application of molecular probes obtained from one species of animals to detect homologous DNA segments in another species. The aim of this study was identification of sex chromosomes in fallow deer (Dama dama), using in interspecies hybridizations in situ (Zoo-FISH technique) the bovine heterosomes painting probes. The resul...
