Phospholipids and cerebrosides of the normal chick sciatic
nerve were extracted by Folch procedures and separated with silica
gel thin-layer chromatography using various chloroform-methanol
solvents. The subsequent chemical assays were expressed as a function
of the developmental stages of the chick from 15 days of incubation
to 7 days after...
Myelin formation in the chick embryo sciatic nerve was examined
during development by analysis of three myelin lipids (cholesterol,
phospholipids, and cerebrosides) and of a myelin related
enzyme (2', 3'-cyclic AMP 3'-phosphohydrolase). The role of the
Schwann cell in controlling the synthesis of these myelin components
was studied by in...
During the 21 day incubation period, the fertile egg provides nutrients such as fatty acids for energy and polyunsaturated fatty acids (PUFA) for membrane synthesis to the developing chick. The hypothesis tested in the present study is that the type of PUFA fed to the breeder hen can alter tissue...
The effects of different dietary lipids on the growth, nutrition
and tissue lipid profiles of rainbow trout raised to market size on a
commercially available ration were examined. Rainbow trout of 80 g
mean initial weight were fed pellets prepared according to Oregon
Moist Pellet specifications for 20 weeks. Salmon...
Stringhalt is a disorder in horses characterized by high stepping with hyperflexion of the hind limbs. This disorder has been reported from the US, Australia, Chile, and Brazil. In most instances, the disease manifests itself in horses exposed to summer dandelion (Hypochaeris radicata). Stringhalt has been induced by feeding summer...

Two experiments were conducted using coturnix quail to determine
the effects of dieldrin and calcium on the reproductive performance
of this species. In both experiments quail were raised on a
soybean-meal glucose-monohydrate ration. At 25% egg production
the quail received diets containing 0, 10 or 25 ppm of dieldrin in...
Normal human skin fibroblast cells were used to study the effect
of zinc supplementation of the media on cell growth and the competitive
binding activity of low density lipoprotein (LDL). Cells were
grown in the media containing Dulbecco's Modified-Eagle Medium (DMEM),
5% (v/v) fetal calf serum (FCS), and various levels...
Mouse embryo cells cultured in vitro in serum-supplemented media undergo growth
crisis, resulting in the loss of genomically normal cells prior to the appearance of
established, aneuploid cell lines. I used the technique of serum-free cell culture to develop
a serum-free mouse embryo (SFME) cell line in which serum was...
Three experiments were conducted in broiler hens to study the influence of dietary n-3 polyunsaturated fatty acids (PUFA) on egg quality, antioxidant status in progeny, and eicosanoid production in tissue. The objective of experiment 1 was to determine the effect of hen age and dietary n-3 PUFA on egg quality...
