Is has been well established that Synthetic Aperture Radar images over oceans can provide wind information over small spatial scales. Since 1999 the Canadian Space Agency has undertaken a joint project, called Hurricane Watch, with the U.S. National Oceanic and Atmospheric Administration / Atlantic Oceanographic and Meteorological Laboratory (NOAA/AOML), the Canadian Department of Fisheries and...

A new method for the determination of linoleic acid (LA) in toothpaste by a routine analysis has been proposed. Studies were based on the ISO 5509 procedure, which was modified for the purpose of LA determination in the toothpaste. Gas chromatography (GC) was employed for the qualitative and quantitative determination of linoleic acid methyl ester. The content of LA (5.31%) in sunflower oil add...

Many natural enemies employ plant- and/or herbivore-derived signals for host/prey location. The larval parasitoid Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) is 1 of 3 biocontrol agents currently being released in an effort to control the emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coloeptera: Burprestidae) in North America. To enhance its efficiency, allelochemicals th...

Abstract For peanuts, roasted at 170 °C, the formation of selected glycerol-bound oxidized fatty acids (GOFAs), namely 9-oxononanoic acid (9-ONA), azelaic (AZA) and octanoic acid, was observed by GC-MS (EI). The content as well AZA increased with continuous roasting time (from 59 mg/kg peanut oil to 101 from not detectable 8 oil, respectively), whereas 9-ONA initially decreased 25 (20 min) agai...

Ethyl linoleate is an unsaturated fatty acid used in many cosmetics for its various attributes, such as antibacterial and anti-inflammatory properties and clinically proven to be an effective anti-acne agent. In this study, we investigated the effect of ethyl linoleate on the melanogenesis and the mechanism underlying its action on melanogenesis in B16F10 murine melanoma cells. Our results reve...

Lipoxygenases have been proposed to be a possible factor that is responsible for the pathology of certain diseases, including ischaemic injury. In the peroxidation process of linoleic acid by lipoxygenase, the E,Z-linoleate allyl radical-lipoxygenase complex seems to be generated as an intermediate. In the present study, we evaluated whether E,Z-linoleate allyl radicals on the enzyme are scaven...

Plasma free fatty acid (FFA) kinetics in humans are often measured with only one tracer. In study 1, healthy volunteers received infusions of [U-¹³C]linoleate, [U-¹³C]oleate, and [U-¹³C]palmitate during continuous feeding with liquid meals low (n = 12) and high (n = 5) in palmitate and containing three labeled fatty acids to measure FFA appearance and fractional spillover of lipoprotein lipase-...

Three-month-old C3H female mice were given injections of 5-mg pieces of mammary adenocarcinoma and were then fed diets that either were fat free or contained saturated fat (15% hydrogenated cottonseed oil) or linoleate (1-15% corn oil). After 6 weeks, the tumors in mice fed the linoleate diet weighed 3-4 times more than those in mice fed the fat-free or saturated-fat diets. Despite a linoleate-...
