Development of the digestive tract and accessory glands of larvae of the fat snook Centropomus parallelus was examined under light microscopy, from hatching to 60 day post-hatching (dph). At hatching, the digestive tract is straight and composed by a cubic cell layer. The exogenous feeding starts at 3 dph, concomitantly with the mouth opening and(More)
Huntington's disease is a neurodegenerative disorder caused by an expansion of CAGs repeats and characterized by alterations in mitochondrial functions. Although changes in Ca(2+) handling have been suggested, the mechanisms involved are not completely understood. The aim of this study was to investigate the possible alterations in Ca(2+) handling capacity(More)
Huntington's disease (HD) is a hereditary dominant neurodegenerative disorder and the progression of the disease may be associated with apoptosis and altered expression of apoptotic proteins. The aim of this study was to investigate gene expression of bax and bcl-2 in tissues from R6/1 transgenic (TGN) mice of different ages (3, 6 and 9 months). The mRNA(More)
Apoptosis is a natural cell elimination process involved in a number of physiological and pathological events. This process can be regulated by members of the Bcl-2 family. Bax, a pro-apoptotic member of this family, accelerates cell death, while the pro-survival member, Bcl-x(L), can antagonize the pro-apoptotic function of Bax to promote cell survival. In(More)
