CrossFit, Inc. has also been criticized for having a "cavalier" attitude towards rhabdomyolysis by promoting a character known as "Uncle Rhabdo" (a cartoon clown dying in a dramatic fashion—hooked up to a dialysis machine, with his kidneys and intestines falling on the floor). In response to this criticism, Greg Glassman stated "We introduced (Uncle) Rhabdo because we're honest and believe that full disclosure of risk is the only ethical thing to do."
After the Internet fitness community began talking about an Ohio State University study that described relatively high injury rates among CrossFitters, the Russes mobilized. They had Glassman's father, Jeffrey Glassman (now "chief scientist" at CrossFit), write a comprehensive rebuttal to the study for the CrossFit website. Berger called each and every research subject who had been reported as injured, to conclude that none actually were hurt, and then added an entire stammering Q&A with one of the paper's authors, kinesiology professor Steven Devor. Here's the kicker: The actual subject of the study was the great improvements in fitness the researchers found in CrossFit athletes. Aside from a handful of sentences, it was all positive.
Evolutionary biologist Marlene Zuk writes that the idea that our genetic makeup today matches that of our ancestors is misconceived, and that in debate Cordain was "taken aback" when told that 10,000 years was "plenty of time" for an evolutionary change in human digestive abilities to have taken place.:114 On this basis Zuk dismisses Cordain's claim that the paleo diet is "the one and only diet that fits our genetic makeup".
Transformed cells adapt metabolism to support tumor initiation and progression. Specific metabolic activities can participate directly in the process of transformation or support the biological processes that enable tumor growth. Exploiting cancer metabolism for clinical benefit requires defining the pathways that are limiting for cancer progression and understanding the context specificity of metabolic preferences and liabilities in malignant cells. Progress toward answering these questions is providing new insight into cancer biology and can guide the more effective targeting of metabolism to help patients.
