Abstract: A nutritional supplement composition that enhances the incorporation of calcium and other bone building elements in bone and that prevents bone breakdown, specifically due to the chronic metabolic acidosis that the typical Western diet generates each day. The transcription factor NFKB (Nuclear Factor Kappa B), which underlies some of this physiology, has also been shown to adversely affect fat metabolism. The enzymatic protein complex, AMP Kinase (Adenosine Monophosphate Kinase), a key regulator of energy metabolism, has been shown to reverse the effects of excessive NFKB activity on bone and fat metabolism. The novel nutrients modulate nutrient partitioning and fat metabolism in a human or animal so as to increase oxidation of fat, decrease storage of fat and promote increased storage of glycogen.

Abstract: A nutritional supplement composition that extends the utility of the prior art methods to include enhanced utility for bone health via modulation of the RANK, RANKL, NFKB signaling system and incorporates unrelated, unforeseen benefits on brain health based on the beneficial impact of the same signaling system on brain health thus preventing loss of neurological function and/or normalizing impaired or deteriorating neurological function in humans based on: (1) mitigation of the adverse impact of dysregulated acid-base balance, (2) dysregulation of prostaglandin physiology, (3) abnormalities in RANK, RANKL, NFKB physiology. reversing elevated NFKB, RANK, RANKL signaling. The nutrients that are ideal for the desired result are Honokiol, Magnolol, Beta-caryophyllene, Palmitoylethanolamide, Hesperidin, Schisandrin, Ferulic Acid, Beta-carotene, Lutein, Lycopene, Sulforaphane, and Ellagic Acid.

Abstract: An instrument for assembling an implant on a neck. The implant and neck being coupled via a taper having a taper axis. The instrument includes a frame having a distal portion and a proximal portion, the distal portion of the frame including a retaining member adapted to engage a portion of the neck and a connector adapted to engage a corresponding feature of the stem. The instrument also includes a force applier retained in the proximal portion of the frame.
