[17] [18] Other azo dyes, which were previously used in textiles, printing, and plastic manufacturing, have been implicated as carcinogens that can cause bladder cancer. [19] While phenazopyridine has never been shown to cause cancer in humans, evidence from animal models suggests that it is potentially ...

The main alcohol dehydrogenase in yeast is larger than the human one, consisting of four rather than just two subunits. It also contains zinc at its catalytic site. Together with the zinc-containing alcohol dehydrogenases of animals and humans, these enzymes from yeasts and many bacteria form the family of "long-chain"-alcohol dehydrogenases.
For many people, there's a hesitation when it comes to "talking about sex, having sex, having good sex, exploring and figuring out what we want sexually." In case you missed: The twisty ...
