Some animals are able to survive for a long time under conditions of drastically reduced oxidative metabolism, called metabolic depression. The most investigated type of metabolic depression is ...

The structure of the oral apparatus in the saprozoically feeding microstomal form of Tetrahymena vorax has been investigated using serial thin sections and isolated preparations. Its general structure ...

A method is described by which large populations of macrostomes may be induced by the presence of 10 mM calcium chloride or 10 mM calcium sulfate to initiate food vacuole formation in the absence of ...

The single-celled ciliated organism Tetrahymena uses a different set of proteins for respiration from plants, animals or yeast, a new study shows. The findings reveal unsuspected diversity in how ...

It's been more than fifty years since scientists discovered that the single-celled organism Tetrahymena thermophila has seven sexes. But in all that time, they've never known how each cell's sex, or ...

Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration -- using oxygen to generate cellular energy -- differently from other organisms such as ...
