Fig. 1 Melting curve analysis of the 267-bp fragment of the 23S rRNA gene obtained with the LightCycler® assay for the wild-type and mutant strains with the A2142G, A2143G, and A2142C mutations. The melting curve corresponding to a mixture containing equal proportions of wild-type, A2142G, and A2142C is also shown, and three melting peaks with the corresponding Tm can be observed. Values on the y axis represent the ratio of the first negative derivative of the change in fluorescence (dF) with the variation in temperature. (View this art in color at www.dekker.com.)

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
