Celiac disease (CD), or gluten-sensitive enteropathy, is one of the most common chronic diseases in childhood but is diagnosed in all ages. CD is a genetically driven immunological intolerance to dietary gluten. Th e treatment is a gluten-free diet. Th e diagnostic criteria are the ESPGHAN criteria, which include the histological characteristics of villous atrophy, crypt hyperplasia and increas...

The genetical analysis of covariance structures is used to explore the genetical and environmental intercorrelations of impulsiveness and sensation seeking factors and their conformity to Eysenck's principal personality dimensions. The independent dimensions of psychoticism, extraversion, neuroticism, and lie scale are not found to give a very satisfactory account of the genetical factor struct...

EPPER vein-banding virus causes a troublesome disease of cultivated peppers I? (Capsicum spp.) in Puerto Rico (ADSUAR 1940) and in Trinidad. A rather similar disease occurs in Hawaii ( KIKUTA 1947). Serological investigations (PEREZ and ADSUAR 1955) indicate that the virus responsible for the West Indian disease is a strain of potato virus Y. In Trinidad, DALE (1954) found that three distinct s...

A biometrical-genetical analysis of twin data to elucidate the determinants of variation in extraversion and its components, sociability and impulsiveness, revealed that both genetical and environmental factors contributed to variation in extraversion, to the variation and covariation of its component scales, and to the interaction between subjects and scales. A large environmental correlation ...

The unusual association of Werdnig-Hoffmann disease and nephrogenic diabetes insipidus in a 5-month-old child is described for the first time. The association is casual, considering the different pathways of genetical transmission in these two diseases. The possibility of identifying the heterozygote is discussed and it appears to be limited to nephrogenic diabetes insipidus.

A biometrical genetical analysis of IgG, IgM, and IgA levels in 134 sets of twins is reported. High heritabilities, around .8, are found for all three immunoglobulin levels, and possible reasons for lower heritabilities found in family studies are discussed. There is evidence for genetical dominance tending to decrease IgM and IgA levels, but there is no evidence for the importance of family en...
