BACKGROUND Topical application of oils and oil-based formulations is common practice in skin care for both adults and infants. Only limited knowledge however is available regarding skin penetration and occlusive potential of oils and common methods for measuring skin moisturization fall short when it comes to the moisturizing effect of oils. OBJECTIVE In this study we used in vivo confocal Ra...

Surfactant enhanced bioremediation (SEB) of oil is an approach adopted to overcome the bioavailability constraints encountered in biotransformation of nonaqueous phase liquid (NAPL) pollutants. Fuel oils contain n-alkanes and other aliphatic hydrocarbons, monoaromatics, and polynuclear aromatic hydrocarbons (PAHs). Although hydrocarbon degrading cultures are abundant in nature, complete biodegr...

β -Lactoglobulin is capable of binding fat-soluble compounds including vitamin A palmitate and is suggested to specifically enhance intestinal uptake of retinol. In this study, bioavailability of a vitamin-A-retinyl palmitate complex in skim milk and in water-based liquids was investigated in vitamin-A-depleted rats. First, rats were fed a vitamin-A-free pellet diet for 6 wk and were thereafter...

BACKGROUND & OBJECTIVES Apoptosis is considered as a major defense mechanism of the body. Multiple pathogens induce macrophage apoptosis as a mode of immune evasion. In earlier studies, n-3 polyunsaturated fatty acids (PUFA) have been reported to be protective against neuronal apoptosis and neuronal degeneration, seen after spinal cord injury. In this study, we tried to evaluate the role of n-3...

Effect of the sex steroids, progesterone (P) and testosterone (T), on 3H-leucine uptake by the brain cells of ovariectomized mice were examined. Animals were divided into four groups, i.e. group 1: control animals treated with sesame oil; group 2: animals treated with P; group 3: animals treated with T, and group 4: animals first treated with T and then with P. Animals in each group were given ...

BACKGROUND/OBJECTIVES Consumption of pine nut oil (PNO) was shown to reduce weight gain and attenuate hepatic steatosis in mice fed a high-fat diet (HFD). The aim of this study was to examine the effects of PNO on both intestinal and hepatic lipid metabolism in mice fed control or HFD. MATERIALS/METHODS Five-week-old C57BL/6 mice were fed control diets containing 10% energy fat from either So...

Fibrous structures are promising candidates for oil–water separation applications. In this study, we have produced poly(styrene-b-isobutylene-b-styrene) thermoplastic elastomeric fibers with the centrifugal spinning fiber production method. The optimal conditions were achieved when using a 25% w/w solution concentration in an 80/20 tetrahydrofuran/toluene (w/w) solvent system at 8000 rpm rotati...

drought is considered as one of the most important limiting factors for oil seed canola plant(brassica napus l.) growth and productivity in iran. on the basis of root and shoot dry weight asaffected by water stress exerted by peg 6000, out of 9 canola cultivars, a relatively tolerant (cv. aghaii)and a sensitive cultivar (cv. po4) were selected. their responses to low water potential with respec...

Early life stages of fish are highly sensitive to crude oil exposure and thus, short term exposures during critical developmental periods could have detrimental consequences for juvenile survival. Here we administered Atlantic haddock ( Melanogrammus aeglefinus ) in (3-day) at two time periods: before first heartbeat, from gastrulation cardiac cone stage early ), heartbeat one day hatching late...
