Estructura de las sales messinienses y de los depósitos sincinematicos asociados en el sector Noreste del surco de Valencia

Se describen tres tipos principales de acumulaciones salinas a partir de la interpretación de los perfiles de sísmica de reflexión de las campañas ENIEPSA-MAP-77 (1977) y WESTERN GEOPHYSICAL COMPANY OF AMERICA-MEDS (1973) en el sector norte del surco de Valencia. Los principales tipos de estructuras salinas son rollers de sal, almohadillas y diapiros que se disponen en tres cinturones paralelos al límite de la sal messiniense.

Aberrant features of the Messinian coral reefs, Spain

Se describen someramente los principales arrecifes del Messiniense en España, haciendo hincapié en el conjunto de 'anomalias' presentan los arrecifes del Neógeno inferior en comparación con las asociaciones arrecifales actuales. Se discute la importancia y significado de Porites sp. como coral claramente dominante, y a menudo exclusivo, en la construcción de edificios arrecifales.

Heterozygous GHR gene mutation in a child with idiopathic short stature.

Abstract Several monogenic defects have been reported to be associated with idiopathic short stature. Focusing on growth hormone receptor (GHR)-gene alterations, the heterozygosity of the same gene defect may be associated with a range of growth deficits. We found a heterozygous mutation (V144I) within exon 6 of the GHR gene in a patient with a low level of insulin-like growth factor I (IGF-I), normal level of GH, and severe short stature. Despite the lack of statistical difference, an overall tendency for reduced wt-GH-induction of GHR activation and Jak/Stat signalling in cells transiently expressing GHR-V144I alone or co-expressing wt-GHR compared to cells expressing only wt-GHR was found when GH doses were increased. Our results suggest that, although GHR sequence variants are responsible for some functional alterations commonly observed in children with idiopathic short stature, these changes may not explain all the height deficits observed in these subjects.
