Centrifugal Clarification of Molasses

The compositions of the various organic and inorganic species in cane molasses show wide variations. Centrifugation can be used to remove suspended so!id particles. The bulk of these are precipitated calcium compounds. Removal of calcium by precipitation and subsequent centrifugation can be enhanced by the addition of sulphuric acid. The effects of dilution, temperature, and acid addition on th...

A test of evolutionary theories of aging.

Senescence is a nearly universal feature of multicellular organisms, and understanding why it occurs is a long-standing problem in biology. The two leading theories posit that aging is due to (i) pleiotropic genes with beneficial early-life effects but deleterious late-life effects ("antagonistic pleiotropy") or (ii) mutations with purely deleterious late-life effects ("mutation accumulation")....

A laboratory test of evolutionary aging theories

high‐throughput chemical genetic screen of chemical compounds from several commercial libraries has revealed that lithocholic bile acid (LCA), and some other bile acids, can slow yeast chronological aging [1]. The robust geroprotective effect of exogenously added LCA is due to its ability to enter chronologically aging yeast cells, be sorted to both mitochondrial membranes and alter mitochondri...
