Changes in histone modifications are an attractive model through which environmental signals, such as diet, could be integrated in the cell for regulating its lifespan. However, evidence linking dietary interventions with specific…
Cytochrome P450 3A4 (CYP3A4) metabolizes ~50% of all clinically used drugs. Although CYP3A4 expression varies widely between individuals, the contribution of genetic factors remains uncertain.
The Plarf is the 4th branch of the People's Liberation Army (PLA) and controls China's arsenal of land-based ballistic, hypersonic, cruise missiles—both nuclear and conventional.
The ancient Egyptians mummified an abundance of cats during the Late Period (664-332 BC). The overlapping morphology and sizes of developing wildcats and domestic cats confounds the identity of mummified cat species.
What explains the genetic relationship between Egyptian cat mummies and modern domestic cats?The study reveals that two of the three analyzed cat mummies contained mitotype sequences similar to modern domestic cats, specifically mitotypes C and G, indicating a genealogical link.How did morphological analysis contribute to identifying species in cat mummies?Morphometric analyses indicated a range of sizes and growth metrics among mummified cats, complicating definitive species identification due to overlapping characteristics.When did ancient Egyptians begin the practice of cat mummification?The first indication of cat mummification dates back to approximately 1350 B.C., associated with burial practices of beloved pets.
