In intact lymphocytes, linoleic acid acts as a typical mitochondrial uncoupler: it substantially decreases the mitochondrial membrane potential and the cellular ATP level, while stimulating oxygen consumption and glycolysis. Under these conditions the inhibition of cellular functions by linoleic acid cannot be attributed to its postulated effects on lipid domains in the plasma membrane.

This paper focused on the assessment of antioxidant property and fatty acid composition of four Centaurea species. The antioxidant activity of its methanol extract was evaluated by several in vitro experiments including phosphomolybedum assay, DPPH assay, β-carotene/linoleic acid, ferric and cupric reducing power. Total phenolic and flavonoid contents were also evaluated. The methanol extract o...

Mammalian cells can metabolize linoleic acid (C,8:2, , , , , ) by A-6-desaturation to y-linoleic acid (C18:3,,,-,,), which can be elongated to dihomo-y-linoleic acid (C211.3,,z, ), and subsequently undergo A-5-desaturation to arachidonic acid (AA) (C211:J,rr-,,) 11 I . Most freshwater fish are also capable o f this process 121, whereas marine species such as turbot (Scopthulmirs maximus) appare...

Lactobacilli convert linoleic acid to hydroxy fatty acids; however, this conversion has not been demonstrated in food fermentations and it remains unknown whether hydroxy fatty acids produced by lactobacilli have antifungal activity. This study aimed to determine whether lactobacilli convert linoleic acid to metabolites with antifungal activity and to assess whether this conversion can be emplo...

Some marine algae can form volatile aldehydes such as n-hexanal, hexenals, and nonenals. In higher plants it is well established that these short-chain aldehydes are formed from C18 fatty acids via actions of lipoxygenase and fatty acid hydroperoxide lyase, however, the biosynthetic pathway in marine algae has not been fully established yet. A brown alga, Laminaria angustata, forms relatively h...

Poly (methyl methacrylate) (PMMA) bone cement is widely used in vertebral body augmentation procedures such as vertebroplasty and balloon kyphoplasty. Filling high modulus PMMA increases the modulus of filled verterbra, increasing the risk of fracture in the adjacent vertebra. On the other hand, in porous PMMA bone cements, wear particle generation and deterioration of mechanical performance ar...

in a relevant proportion of cases, perhaps in most patients carrying the PKD 1 mutation, ADPKD may start as early as the 12th week of gestation. This contrasts with the late appearance of clinical signs and symptoms which do not appear before the third to fifth decade in many individuals. We believe that ADPKD starts in fetal life in a substantial number of cases, implicating the first function...

Atherosclerosis can be defined as the development of abnormal fat deposits in the artery wall. Atherosclerotic lesions are believed to progress through a focal, lipid-filled foam cell stage (fatty streak) into an advanced, complicated lesion that contains abundant extracellular cholesterol ester in the atheromatous gruel within the arterial intima. Weakening of the arterial wall and/or rupture ...

Linoleic acid was isolated from both the methanol extracts of proso and Japanese millet as a histone deacetylase inhibitor. It showed uncompetitive inhibitory activity toward histone deacetylase (IC(50)=0.51 mM) and potent cytotoxicity toward human leukemia K562 (IC(50)=68 microM) and prostate cancer LNCaP cells (IC(50)=193 microM). Millet containing linoleic acid might have anti-tumor activity.
