摘要:
Skin care products which contain as a vitamin C component 6-O-PUFA ascorbates represented by general formula (I): RCO-A (I) where RCO— is an acyl group derived from a polyunsaturated fatty acid, and A is a residue of ascorbic acid that binds by —O— derived from the hydroxyl group in ascorbic acid. The products show improved transfer of ascorbic acid to tissues or cells, allow the functions of ascorbic acid to be exhibited efficiently, and also have the potential to show the functions of PUFAs. Also provided are foods and beverages that contain 6-O-PUFA ascorbates represented by general formula (I).

摘要:
The object of the present invention is to provide a composition that has preventive or ameliorative action on symptoms or diseases caused by decreased brain function. This composition contains, as its active ingredient, arachidonic acid and/or a compound having arachidonic acid as a constituent fatty acid and, particularly, an alcohol ester of arachidonic acid or a triglyceride, phospholipid or glycolipid in which all or a portion of the constituent fatty acids are arachidonic acid.
摘要:
A composition having a normalizing action for infradian rhythm and/or a synchronization promoting action for circadian rhythm (biological clock) containing arachidonic acid and/or an arachidonic acid-containing compound.

摘要:
An oil or fat composition according to the present invention contains a LCPUFA supply compound as a first component, and phospholipids as a second component, the LCPUFA supply compound containing LCPUFA in its structure and being hydrolyzable to remove its LCPUFA, wherein respective proportions of the first component and the second component are determined according to the number of hydrolyzable fatty acid bonds contained in the phospholipid molecules. The phospholipids and LCPUFA supply compound are metabolized to LCPUFA-PL in the body and absorbed. As a result, an oil or fat composition is provided that can efficiently increase the LCPUFA-PL level in the body. This is realized without directly using the phospholipids (LCPUFA-PL) whose constituents are long-chain polyunsaturated fatty acids (LCPUFA), taking into account the metabolism in the body.
摘要:
A composition incorporating at least one sesamin-class compound is enhanced in the anti-fatigue action of sesamin class compounds by additionally incorporating at least one vitamin B1 class compound. Also provided is an anti-fatigue agent containing at least one sesamin-class compound and at least one vitamin B1 class compound as the active ingredients.
摘要:
A composition and food or beverage containing arachidonic acid or a compound having arachidonic acid as a component fatty acid and having an action preventing or alleviating symptoms or diseases due to aging of the blood vessels.
摘要:
A motion compensation device to compensate for motion of an optical system causing image blur, and having a position detection device to detect a position of a motion compensation optical system relative to a lens barrel. The position detection device includes an LED to emit light, a position sensing device (PSD) to sense light received from the LED and a light screening device having a slit between the LED and PSD. The lens barrel includes a movable tube to which the LED is fixed, and a fixed tube to which the PSD is fixed. During photography, the movable tube moves in the optical axis direction from a collapsed state causing the distance between the LED and the PSD to become long, and causing a light ray emitted from the LED and incident on the slit to form a small angle with a line perpendicular to the center of the slit. As a result, an error which arises between the position of a light ray incident on a light receiving surface of the PSD and the actual position of the slit is small, and the precision of position detection of the motion compensation optical system increases. When photography does not occur, the movable tube moves in the optical axis direction and retracts into the fixed tube. As a result, the distance between the LED and PSD is short, resulting in a smaller lens barrel.
摘要:
Anti-fatigue agents containing dioxabicyclo[3.3.0]octane derivatives such as sesamin which is an ingredient contained in sesame, as well as pharmaceutical compositions and physiologically functional foods that contain such anti-fatigue agents are disclosed. These compounds can safely be administered to humans and animals alike and hence allow for continued ingestion while proving effective in promoting an improvement of stamina, an increase of body strength, a relief of fatigue, and recovery from fatigue.
