BACKGROUND Decreased muscle strength can lead to adverse health outcomes in the elderly. A potential association between phthalate exposure and muscle strength was suggested previously, but has not been investigated directly. We hypothesized that phthalate exposure is associated with lower handgrip strength and that the association is modified by the dietary omega-6 to omega-3 ratio. METHODS ...

The concentration of selenium (Se) in food is in many countries too low and the ratio between omega-6 and omega-3 fatty acids too high implying more non-communicable diseases, e.g. cancer, cardiac disease, impaired immune defense, pain, enhanced non-infectious inflammatory response. Meat from animals supplemented with Se and omega-3 fatty acids makes a good source of these nutrients in human nu...

OBJECTIVE To review the role of essential fatty acids in brain membrane function and in the genesis of psychiatric disease. METHOD Medline databases were searched for published articles with links among the following key words: essential fatty acids, omega-3 fatty acids, docosahexanoic acid, eicosapentanoic acid, arachidonic acid, neurotransmission, phospholipase A2, depression, schizophrenia...

We obtain some inequalities related to the powers of numerical radius inequalities of Hilbert space operators. Some results that employ the Hermite-Hadamard inequality for vectors in normed linear spaces are also obtained. We improve and generalize some inequalities with respect to Specht's ratio. Among them, we show that, if $A, Bin mathcal{B(mathcal{H})}$ satisfy in some conditions, it follow...

BACKGROUND The traditional diet of Inuit people comprises large amounts of fish and marine mammals that are rich in omega-3 polyunsaturated fatty acids (PUFAs). Results from in vitro studies, laboratory animal experiments and population studies suggest that omega-3 PUFA intake and a high omega-3/omega-6 ratio exert a positive effect on bone health. OBJECTIVE This longitudinal study was conduc...

mega-3 fatty acids found in some foods have a wide-range of health benefits. The omega-3 supplementation results in higher antioxidant activity in human seminal fluid and enhanced sperm count, sperm motility, and sperm morphology. Considerable number of infertile men with idiopathic oligoasthenoteratozoospermia might be benefit from omega-3 fatty acids administration. Infertility caused by idio...
