Petroleum-oil sprays and fogs are used increasingly to control insect pests of economic plants. These oils are useful in controlling the aphid vectors of potato virus, but it is first necessary to learn which oils are tolerated by potato leaves. Hence, undiluted oils and cresoap emulsions of petroleum oils were tested on potato leaves to determine: (1) The rates of oil penetration into leaves; ...

How the oil spill compositions change in the weathering process is an important topic for marine environment protection. In this study, long-term weathering simulation tests were conducted for 2 kinds of crude oils from the platforms of different blocks in Bohai Sea and 2 kinds of heavy marine fuel oils. Both floating oils and oils sunken in the seawater were analyzed. Gas chromatography (GC) r...

Commercially prepared and packaged soybean ::md cottonseed salad oils from several different processors were evaluated penodically during storage for 12 months. Panially hydrogenated and winterized soybean oils, as well as unhydrogenated soybean salad oils. were stored in bottles and cans at i8 and 100 F. Control samples of all oils were held at a F during the entire test. Some lots in bottles ...

Research on the biological effects of essential oils on human skin cells is scarce. In the current study, we primarily explored the biological activities of 10 essential oils (nine single and one blend) in a pre-inflamed human dermal fibroblast system that simulated chronic inflammation. We measured levels of proteins critical for inflammation, immune responses, and tissue-remodeling processes....

Vidrih R., Vidakovič S., Abramovič H. (2010): Biochemical parameters and oxidative resistance to thermal treatment of refined and unrefined vegetable edible oils. Czech J. Food Sci., 28: 376–384. In human nutrition fats are physiologically important food constituents but also the components most liable to oxidative degradation. The oils included in the study were refined (sunflower, extra-sunfl...

Thymus species are popular spices and contain volatile oils as main chemical constituents. Recently, plant-derived essential oils are gaining significant attention due to their significant biological activities. Seven different thymus-derived essential oils were compared in our study. First, we focused on their chemical composition, which was followed up by testing their effects on phagocytosis...

Received Sep 2, 2016 Revised Aug 2, 2017 Accepted Aug 30, 2017 For decades, petroleum-based mineral oils are the insulating media conventionally used in the industry, particularly for high voltage (HV) applications. However, due to the disadvantages of mineral oils, there is growing interest in replacing these oils with environmentally friendly alternatives in order to fulfill the demanding req...

Lipid-based drug delivery systems in the form of triglyceride emulsions, micellar systems and liposomes have been used for parenteral administration for the last few decades. Large number of new chemical entities (NCE) presents formulation and bioavailability problems because of the dose and poor solubility in solvent and co-solvent systems. In addition, high drug concentrations can lead to irr...

The data presented show the ability of subinhibitory concentrations of plant essential oils to influence the production of enterotoxins A and B and alpha-toxin by Staphylococcus aureus. Subinhibitory concentrations of the oils of bay, clove, cinnamon, nutmeg and thyme had no significant effect on the overall quantity of extracellular protein produced. Haemolysis due to alpha-toxin was significa...

BACKGROUND The paper looks at the levels of canolol, tocopherols and antioxidant activity in cold-pressed and hot-pressed rapeseed oils produced from seeds of various moisture levels (5%, 7.5%, and 10%). The paper also considers the effects of seed roasting on the levels of these compounds. METHODS The material used for the tests was rapeseed cv. Adrianna. The quality of the oils obtained is ...
