How can some people live at high altitudes and thrive while others struggle?

The answer for Tibetans who live at altitudes around 14,000 feet is increased nitric oxide (NO) levels. High levels of NO circulate in various forms in the blood and produce the physiological mechanisms that cause the increased blood flow that maintains oxygen delivery despite hypoxia - low levels of oxygen in the ambient air and the bloodstream.

Copper transporter plays an unexpected role in the absorption of cisplatin

Platinum complexes such as the well-known cisplatin are powerful antitumor medications. They cross the cell membrane and reach the nucleus, where they attach to DNA and stop cell growth. But how does cisplatin get to the nucleus?
