The effects of aliphatic hydrocarbons--methane, ethane, propane, butane, and their mixture--on the photosynthetic apparatus of maize (Zea mays) and raygrass (Arrhenetherum elatius) leaves have been studied. The pathology of subcellular organelles as well as of the whole architectonics of the cell
The effect of in vivo lipid peroxidation on the excretion of immunoreactive prostaglandin E2 (PGE2) in the urine of rats was studied. Weanling, male Sprague-Dawley rats were fed a vitamin E-deficient diet containing 10% tocopherol-stripped corn oil (CO) or 5% cod liver oil (CLO) with or without 40
Plant growth promoting rhizobacteria attain increasing importance in agriculture as biofertilizers and biocontrol agents. These properties significantly depend on the formation of bioactive compounds produced by such organisms. In our work we investigated the biosynthetic potential of 13
Environmental contamination by hydrocarbons is a major problem, and hydrocarbon accumulation in soil poses hazardous threat to ecosystems. Phytoremediation, which involves plants, is an encouraging technique for the removal of hydrocarbons from polluted soil and water. The purpose of this
The increased expiration of ethane and pentane by mice treated with hepatotoxic doses of acetaminophen suggests the possibility of oxidant mechanisms associated with the necrosis. However, studies in rats are not consistent with oxidant stress mechanisms causing the damage, because acetaminophen
Our previous studies have indicated that pups born from mothers fed lipids obtained from yeast (Candida lypolitica) grown on n-alkanes during pregnancy and lactation show an acceleration of myelinogenesis. In the present work we carried out experiments using an undernutrition model to establish if
Five groups of female mice were fed from day 14 of pregnancy and throughout lactation on synthetic diets differing only in the lipid component, which constituted 10% of the diet and was derived from (a) the lipid fraction extracted from yeast grown on n-alkanes, (b) commercial soya lecithin, (c)
The cuticular lipid composition of lower and upper leaves of five genotypes of field-grown corn,Zea mays L., was determined by combined gas chromatography-mass spectrometry. Surface lipids of the upper leaves had a higher proportion ofn-alkanes (45-52%) than the lower leaves, while the lower leaves
Prior work has examined cuticle function, composition, and ultrastructure in many plant species, but much remains to be learned about how these features are related. This study aims to elucidate relationships between these features via analysis of cuticle development in adult maize
