Essential fatty acids (EFA) have proved to be important for normal bone mineral density (BMD) and bone growth in animal studies. Patients with cystic fibrosis often have low serum EFA levels, and low BMD has also been reported in patients with normal anthropometry. The aim of the present study was to analyse if BMD during a 2-year period was related to fatty acid status in patients with cystic ...

Essential fatty acid (EFA) deficiency exerts a beneficial effect on immune-mediated glomerulonephritis, preventing both the tissue injury and consequent mortality. Because both macrophages and eicosanoids are thought to play pathogenic roles in glomerulonephritis, and because macrophages play an important role in modulating arachidonate metabolism at sites of renal injury, the effects of EFA de...

Exploratory factor analysis (EFA) of the Psychopathic Personality Inventory (PPI; S. O. Lilienfeld, 1990; S. O. Lilienfeld & B. P. Andrews, 1996) with a community sample has suggested that the PPI subscales may comprise 2 higher order factors (S. D. Benning, C. J. Patrick, B. M. Hicks, D. M. Blonigen, & R. F. Krueger, 2003). However, substantive and structural evidence raises concerns about the...

Leukotriene (LT) B4 is an important pro-inflammatory autocoid. In order to investigate the potential role of this eicosanoid in renal inflammation, in this study we determined the capability of glomeruli to synthesize this mediator. Glomeruli were able to synthesize LTB4 when provided with exogenous substrate in a dose-dependent fashion in the presence of ionophore A23187. Ionophore, although b...

Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), path analysis, and structural equation modeling (SEM) have long histories in clinical research. Although CFA has largely superseded EFA, CFAs of multidimensional constructs typically fail to meet standards of good measurement: goodness of fit, measurement invariance, lack of differential item functioning, and well-differe...

Development of the Woodcock-Johnson (3rd ed.; WJ-III; Woodcock, McGrew & Mather, 2001a) was guided in part by Carroll's (1993) 3-stratum theory of cognitive abilities and based on confirmatory factor analysis (CFA), even though Carroll used exploratory factor analysis (EFA) to derive his theory. Using CFA, McGrew and Woodcock (2001) found a 9-factor model across all age ranges. To determine if ...

When weanling rats are reared on a fat-free diet for about 10 weeks they develop, as originally shown by Burr & Burr (1929), certain signs of a nutritional deficiency. The signs can be cured or prevented by the inclusion of essential fatty acids (EFA), as linoleic acid, in the diet and the condition is therefore termed EFA deficiency. The weanling male rat has been used extensively in studies c...

In the 40 years since the essentiality of polyunsaturated fatty acids (PUFA) in fish was first established by determining quantitative requirements for 18:3n-3 and 18:2n-6 in rainbow trout, essential fatty acid (EFA) research has gone through distinct phases. For 20 years the focus was primarily on determining qualitative and quantitative EFA requirements of fish species. Nutritional and bioche...

In order to study the response of a poorly differentiated tumor to nutritional manipulation, the Yoshida ascites hepatoma (AH 130) was grown in rats fed an essential fatty acid (EFA)-deficient diet and in rats fed a control diet. Hepatomas, livers, and blood plasma from host rats and normal rats were studied as to the effects of EFA deficiency on the lipid composition. Normal rats fed an EFA-de...
