Abstract: A household cooking range comprises a housing defining a cooking cavity, the housing being selected from one of multiple housings with different configurations, and a modular frame chassis supporting the selected housing and cooking cavity.

Abstract: A nucleic acid formulation for use in gene delivery comprising a nucleic acid and an anionic polymer is disclosed. Examples of the anionic polymer includes anionic amino acid polymer or poly-amino acid (such as poly-L-glutamic acid, poly-D-glutamic acid, poly-L-aspartic acid, poly-D-aspartic acid), poly-acrylic acid, polynucleotides, poly galacturonic acid, and poly vinyl sulfate.

Abstract: A lumber support device and a selective stabilization support device for use in conjunction with a method of determining and treating mechanical lower back pain such as the McKenzie Approach. The lumber support device includes a semi-rigid member for positioning around the user's abdomen, the member includes a semi-rigid member for positioning around the user's abdomen. The semi-rigid member helps to prevent excessive trunk bending by the patient. At least one tensioning strap is also provided connectable at first and second end regions to a surface of the semi-rigid member. Preferably, two crossed tensioning straps are provided. The straps are provided to encircle the user's torso so as to maintain the lumber support device in position. An adjustable attachment means, for example in the form of a clip, is attached to the straps. The adjustable attachment means is movable laterally along the strap.

Abstract: An electroporation device which may be used to effectively facilitate the introduction of a macromolecule into cells of a selected tissue in a body or plant. The electroporation device comprises an electro-kinetic device (“EKD”) whose operation is specified by software or firmware. The EKD produces a series of programmable constant-current pulse patterns between electrodes in an array based on user control and input of the pulse parameters and allows the storage and acquisition of current waveform data. The electroporation device also comprises a replaceable electrode disk having an array of needle electrodes, a central injection channel for an injection needle, and a removable guide disk.
