effects of n-3 or n-6 polyunsaturated fatty acids alone or in combination with vitamin e on male breeders’ fatty acid composition of spermatozoa, fertility and lipid peroxidation were studied. fish oil increased c22:6 n-3 and decreased c22:4 n-6 in the spermatozoa (p

The rationale for issuing poison pill securities remains unclear, despite the findings of a large body of prior research that these defenses adversely affect shareholder wealth. This paper investigates the hypothesis that the adoption of such defenses may reflect shareholders’ desire to contract efficiently with their managers in an environment characterized by hostile takeovers and uncertainty...

Anthocyanins, Flavonoids, Biosynthesis, Flavanon 3-Hydroxylase, Flavonoid 3'-Hydroxylase, Matthiola incana Enzyme preparations from flowers of defined genotypes o f Matthiola incana contain two dif­ ferent hydroxylases for hydroxylation of naringenin in the 3and 3'-position, respectively. The 3-hydroxylase is a soluble enzyme and requires as cofactors 2-oxoglutarate, Fe2+ and ascorbate. Besides...

A large body of research shows that adults will form illusory correlations in the course of category learning. Surprisingly little research has examined illusory correlations among children. Two experiments examined the formation of the illusory correlation in 3and 5-yearolds. Experiment 1 provides evidence that these young children will not form illusory correlations in a novel categorization ...

The existence and characteristics of bone marrow T-ceII progenitors have not yet been established in man. Several pieces of evidence such as the reconstitution of certain immunodeficiencies by bone marrow graft suggest that T-ceIl precursors are present in the bone marrow. We report the growth of T-ceII colonies from bone marrow populations using PHA-stimulated lymphocyte-conditioned medium con...

The effective apparatus deadspace of the Magill, Potter and Cape Town gas circuits has been investigated using a model system simulating 3and 8-year-old children. (1) The Cape Town system is more suitable for smaller children. (2) The Potter system is more suitable for larger children. (3) A generous fresh gas flow will decrease the deadspace of the Potter and the Cape Town systems. A flow of d...

Nearly 40 years ago, the High/Scope Perry Preschool Project developed a high-quality educational approach focusing on 3and 4-year-olds at risk for school failure. The longitudinal study has found that not only was the project effective as an educational intervention, it also demonstrated other positive outcomes, including a significantly lower rate of crime and delinquency and a lower incidence...
