Neoteny, Prolongation of Youth: From Naked Mole Rats to "Naked Apes" (Humans).

It has been suggested that highly social mammals, such as naked mole rats and humans, are long-lived due to neoteny (the prolongation of youth). In both species, aging cannot operate as a mechanism facilitating natural selection because the pressure of this selection is strongly reduced due to ) a specific social structure where only the "queen" and her "husband(s)" are involved in reproduction (naked mole rats) or ) substituting fast technological progress for slow biological evolution (humans). Lists of numerous traits of youth that do not disappear with age in naked mole rats and humans are presented and discussed.

In search of novel highly active mitochondria-targeted antioxidants: thymoquinone and its cationic derivatives.

Since the times of the Bible, an extract of black cumin seeds was used as a medicine to treat many human pathologies. Thymoquinone (2-demethylplastoquinone derivative) was identified as an active antioxidant component of this extract. Recently, it was shown that conjugates of plastoquinone and penetrating cations are potent mitochondria-targeted antioxidants effective in treating a large number of age-related pathologies.
