摘要:
The present invention relates to processes for production of Very Long Chain Polyunsaturated Fatty Acids (VLC-PUFAs). The present invention also relates to compositions (e.g., nutritional supplements and food products) containing such VLC-PUFAs. In one embodiment, the present invention is directed to methods for biosynthesis and production of the VLC-PUFAs described herein (particularly C28-C38 PUFAs, also referred to herein as supraenes or supraenoics) by the expression, in a production host cell, of the full or partial sequence(s) of Elovl4 DNA/mRNA nucleic acids or ELOVL4 protein sequences encoded thereby, from any species (prokaryotic or eukaryotic) for use in the biosynthesis, production, purification and utilization of VLC-PUFAs in particular by the elongation of C18-C26 saturated fatty acids and PUFAs. The composition of the invention comprises, in various embodiments, a dietary supplement, a food product, a pharmaceutical formulation, a humanized animal milk, an infant formula, a cosmetic item and a biodiesel fuel for example. A pharmaceutical formulation can include, but is not limited to: a drug for treatment of neurodegenerative disease, a retinal disorder, age related maculopathy, a fertility disorder, particularly regarding sperm or testes, or a skin disorder.

A cabinet is provided with a curved, upwardly-swinging door and interior shelves. The curved shelf door is mounted on a pair of opposed arms which rotate on a horizontal axis. Each arm is provided with two opposed, circularly arcuate slots and a central ellipsoidal slot, each slot engaging a fixed stud at the side of the cabinet. The ellipsoidal slot and its corresponding stud provide a center pivot for each of the arms. The arms are mounted inside the cabinet on opposed interior side walls. Lighting can be provided in a formed recess in the bottom of the cabinet. The cabinet can also be provided with plural internal shelves supported on planar brackets. The cabinet further can be provided with a pair of side-by-side doors and a center wall. Arms are mounted on each side of the center wall and adjacent the interior side walls of the cabinet, for separately mounting the doors.

An electrical heating cable which limits power output once an established temperature limit is reached. The cable includes a high-resistance element and a temperature-sensitive variable resistance element electrically connected in series between two electrical conductors otherwise insulated from each other by insulating material. The temperature-sensitive resistance undergoes a substantial positive increase in resistivity when the temperature of the cable nears the established temperature limit. The increase in resistivity substantially reduces the heat-generating current flowing in the cable to limit the power output.

A bed frame includes a base frame, an articulated support decks, an intermediate frame positioned between the base frame and the articulated support deck, and an auto-contour mechanism. The articulated support deck includes head, seat and foot deck portions. When engaged, the auto-contour mechanism adjusts the elevation of the seat deck portion and the foot deck portion in response to an adjustment of the head deck portion. The auto-contour mechanism is easily engaged/disengaged by manipulating a control lever. The bed frame can include siderails which are provided with a latching mechanism. The bed frame can also include a caster assembly that allows casters to be pivoted in an engaged position in which the bed frame rests on the casters, and a disengaged position in which the bed frame rests on legs.

A technique is provided for removing foam mandrel material from a stiffener section of a composite structural member as is employed in lightweight aircraft skin structures. The technique involves the direct pressure glass bead blasting of the mandrel material. By mounting a blasting nozzle within a rubber hose of larger diameter, an airstream containing glass beads may be directed outwardly through the nozzle while evacuating pressure is created in an annular passageway between the hose and the nozzle to evacuate mandrel foam particles as well as spent glass beads. The result is a clean channel within the stiffener section.

There is disclosed lubricant additives that comprise a combination of meadowfoam oil as a triglyceride or a wax ester, sulfurized triglyceride meadowfoam oil or sulfurized wax ester of meadowfoam oil, and phosphite adducts of triglyceride meadowfoam oil or wax ester of meadowfoam oil. There is also disclosed a process for sulfurizing triglyceride meadowfoam oil that is soluble in a lubricant base, such as mineral oil.

The invention relates to an expansion fastener device that secures two interlocking members together. The device includes a parallelepiped receptacle having slits along opposite ends. The receptacle is inserted through the interlocking members and double wedges are driven into the receptacle. The double wedges includes a first wedge having tapers in the vertical direction and its insertion into receptacle causes only vertical expansion of the receptacle. A second horizontal tapered wedge is received with a horizontal tapered opening formed in the first wedge to cause independent expansion of the recess in the horizontal direction.
