Looking at everything from the Man of Steel's muscle tissue – his skin density "would have to be 296 g/cm3 to stop 50% of standard handgun bullets" – to how he reverses the polarity of the Earth's spin (he increases his relativistic mass by 13.7m times by travelling close to the speed of light, they write), Superman is the "the number one candidate for 'most powerful superhero'".
Multiple factors contribute to the difficulties in treating skeletal muscle: the sheer mass of muscle tissue; the low density of the receptor responsible for the uptake and delivery of the recombinant enzyme to the lysosomes; and the diversion of the enzyme to the liver.
Monomeric mitochondrial F1Fo ATP synthase was purified from bovine heart muscle tissue by sucrose density gradient centrifugation and ion-exchange chromatography.
That is, decrease in muscle tissue and ICC densities is topographically directly linked with the extent of the mega-syndrome.
In some studies, it increased bone density and muscle tissue.
The muscle-specific force, a measure of intrinsic force generation of muscle, was calculated using the maximal isometric force, the muscle mass, and the fiber length according the following equation: specific force=maximal isometric force/(muscle mass × (density of muscle tissue * fiber length -1).
Ten µm thick sections were stained with lectin from Bandeiraea simplicifolia (BS-1, Sigma-Aldrich, Germany) or with von Willebrand factor (vWF; AB7356, Chemicon, USA) in order to determine capillary density in the muscle tissue.
According to Nishida et al. [ 17], intramuscular lipoma is a (1) lesion located within the muscle and (2) a fat density lesion containing thick soft tissue density streaks of variable thickness and occasional interruption, representing the entrapped muscle fibers.
Last year, researchers at the Canadian Centre for Activity and Aging, for instance, examined muscle tissue from older competitive runners, checking for the density of their motor units, a measure of muscle health.
The fold-change distributions (THI/vehicle) for genes associated with metabolism, muscle tissue and inflammation are displayed in the form of a density distribution plot (Fig. 5H).
