摘要:
The present invention relates to novel diacylglycerol acyltransferase genes and proteins, and methods of their use. In particular, the invention describes genes encoding proteins having diacylglycerol acetyltransferase activity, specifically for transferring an acetyl group to a diacylglycerol substrate to form acetyl-Triacylglycerols (ac-TAGS), for example, a 3-acetyl-1,2-diacyl-sn-glycerol. The present invention encompasses both native and recombinant wild-type forms of the transferase, as well as mutants and variant forms. The present invention also relates to methods of using novel diacylglycerol acyltransferase genes and proteins, including their expression in transgenic organisms at commercially viable levels, for increasing production of 3-acetyl-1,2-diacyl-sn-glycerols in plant oils and altering the composition of oils produced by microorganisms, such as yeast, by increasing ac-TAG production. Additionally, oils produced by methods of the present inventions comprising genes and proteins are contemplated for use as biodiesel fuel, in polymer production and as naturally produced food oils with reduced calories.

The present invention provides cyclopropane fatty acid synthase genes and proteins, and methods of their use. The present invention encompasses both native and recombinant wild-type forms of the synthase, as well as mutants and variant forms, some of which possess altered characteristics relative to the wild-type synthase. The present invention also provides methods of using cyclopropane fatty acid synthase genes and proteins, including in their expression in transgenic organisms and in the production of cyclopropane fatty acids in plant oils, and in particular seed oils.
摘要:
A device for exercising internal and external muscles of the leg is provided. The device includes a foot holder for pivotally supporting a user's foot. The foot holder is capable of pivoting around an axis which is substantially perpendicular to the foot, and near the front of the user's leg. The device also includes a tension control unit for providing constant resistance to pivoting of the foot holder. The device preferably has separate foot holders and hydraulic tension control units for each foot.

An electrical connection element for providing an electrical connection to a porous material may include a first electrically conductive plate disposed on at least a portion of a first side of the porous material. A second electrically conductive plate may be disposed on at least a portion of a second side of the porous material, opposite to the first side. An electrically conductive material may impregnate the porous material in a region between the first and second electrically conductive plates, and an electrical connector may be attached to at least one of the first and second electrically conductive plates.
摘要:
A whipstock assembly includes a whipstock body 8 having a whipstock center of gravity offset radially from the central axis of the whipstock body, a counterweight to releasably secured to the whipstock body, with a counterweight having an offset counterweight center of gravity, an orientation device 5, and a neutralizer 11. The neutralizer causes the combined whipstock/neutralizer center of gravity to be substantially closer to the central axis of the whipstock body compared to the whipstock center of gravity. An attaching mechanism 6, 12 allows the neutralizer to be returned to the surface after the whipstock body is set in the well.
