Ellis-van Creveld (EvC) syndrome is a human autosomal recessive disorder caused by a mutation in either the EVC or EVC2 gene, and presents with short limbs, polydactyly, and ectodermal and heart defects. The aim of this study was to understand the pathologic basis by which deletions in the EVC2 gene lead to chondrodysplastic dwarfism and to describe the morphologic, immunohistochemical, and molecular hallmarks of EvC syndrome in cattle. Five Grey Alpine calves, with a known mutation in the EVC2 gene, were autopsied. Immunohistochemistry was performed on bone using antibodies to collagen II, collagen X, sonic hedgehog, fibroblast growth factor 2, and Ki67. Reverse transcription polymerase chain reaction was performed to analyze EVC1 and EVC2 gene expression. Autopsy revealed long bones that were severely reduced in length, as well as genital and heart defects. Collagen II was detected in control calves in the resting, proliferative, and hypertrophic zones and in the primary and secondary spongiosa, with a loss of labeling in the resting zone of 2 dwarfs. Collagen X was expressed in hypertrophic zone in the controls but was absent in the EvC cases. In affected calves and controls, sonic hedgehog labeled hypertrophic chondrocytes and primary and secondary spongiosa similarly. FGF2 was expressed in chondrocytes of all growth plate zones in the control calves but was lost in most EvC cases. The Ki67 index was lower in cases compared with controls. EVC and EVC2 transcripts were detected. Our data suggest that EvC syndrome of Grey Alpine cattle is a disorder of chondrocyte differentiation, with accelerated differentiation and premature hypertrophy of chondrocytes, and could be a spontaneous model for the equivalent human disease.

Bachofens Mutterrecht – längst ein Klassiker. Mit seiner These vom Matriarchat als ursprünglicher Gesellschaftsform war Bachofen der Erste, der es wagte, über eine geschichtliche Bedingtheit der Geschlechterrollen zu spekulieren und darüber, dass das Patriarchat eine vorübergehende Erscheinung sein könnte. Er half damit, die Krise der Männlichkeit zu bearbeiten, die sich nach dem verlorenen Krieg in den 20er Jahren besonders zuspitzte. Generationen von Autoren wurden von ihm beeinflusst; gelesen haben sie den Text – in der Kröner-Ausgabe. Zum 200. Geburtstag des Basler Altertumsforschers und Juristen erscheint die Auswahl seiner wirkungsmächtigsten Texte, die ab 1925 in mehreren kommentierten Auflagen im Kröner-Verlag erschien, erneut. Neben dem Mutterrecht (1861) enthält sie den Versuch über die Gräbersymbolik der Alten (1859) und Die Sage von Tanaquil (1870), neu und ausführlich eingeleitet von Yahya Elsaghe.
