Optical light curves and spectra of the Type Ia supernova 1986G in NGC 5128 (Centaurus A) are presented. Although spectral evolution closely resembled that more common "slower" photometric classes supernovae, subtle differences maximum-light were detected. The expansion velocity photosphere SN decreased rapidly at early phases. appears to have been heavily obscured by dust lane 5128.

The second-largest cause of X-linked mental retardation is a deficiency in creatine transporter (CRT; encoded by SLC6A8), which leads to speech and language disorders with severe cognitive impairment. This syndrome, caused the absence brain, currently untreatable because CRT required for entry into brain cells. Here, we developed brain-specific Slc6a8 knockout mouse (Slc6a8-/y) as an animal model human order explore potential therapies this syndrome. phenotype Slc6a8-/y was comparable that...
ABSTRACT The ability of Pseudomonas aeruginosa to develop resistance most antimicrobials represents an important clinical threat worldwide. We report the dissemination in several Colombian hospitals two predominant lineages extensively drug-resistant (XDR) carbapenemase-producing P. strains. These belong high-risk clones sequence type 111 (ST111) and ST235 harbor bla VIM-2 on a class 1 integron KPC-2 Tn 4401 transposon, respectively. Additionally, ST1492, novel single-locus variant ST111,...
Near-infrared small-dispersion spectra obtained with a grism at the prime focus of CTIO's 4-m telescope were used to survey and classify late-type red giants found in circular area diameter 24.4 arcmin which is contained within Baade's Window. The most significant feature its completeness up distance that reaches, for late M giants, past galactic nuclear bulge. stars presented here constitute, therefore, unique complete sample giant population Out very large number found, 306, including all...
