One more U.S. Embassy employee in Havana, Cuba, has been affected by mysterious health incidents, the State Department said.

State Department spokeswoman Heather Nauert said one of two Americans recently evacuated from Cuba was “medically confirmed” to have been affected, while the other was “still being evaluated” by doctors.

25 Americans affected

In all, 25 Americans have been affected by the mystery ailment in Cuba.

“We still don’t know, to this day, what is causing it and who is responsible,” Nauert said, noting that investigations were underway in Havana as well as Guangzhou, China, where one employee experienced similar symptoms recently.

The United States has said that the Cuba incidents started in late 2016. The State Department calls them “specific attacks” but has not said what caused them or who was behind them. Cuba has adamantly denied involvement or knowledge.

Initial speculation centered on some type of sonic attack owing to strange sounds heard by those affected, but an interim FBI report in January found no evidence that sound waves could have caused the damage, The Associated Press has reported.

Warning issued in China

The State Department issued a health warning after the employee in China reported experiencing “subtle and vague, but abnormal, sensations of sound and pressure” and was diagnosed with a mild traumatic brain injury.

Secretary of State Mike Pompeo described it as a “serious medical incident.”

The new confirmation came less than a week after the U.S. renewed demands on Cuba to determine the source of the “attacks” on U.S. diplomats. Cuba responded by again denying any involvement in or knowledge of any such attacks. (VOA)

Protein Identified Enables New Drugs to Increase ‘Good Cholesterol’ Levels

ORP2 could offer a new strategic line of research and possibly succeed where the use of statins in this area hasn't, Yang noted.

Researchers have identified a protein, known as ORP2, responsible for transporting cholesterol inside cells that opens the way for new drugs to increase the body’s ‘good cholesterol’ levels.

ORP2 can increase the amount of cholesterol in cells, a process called cholesterol efflux. We think this pathway will be very important for the development of a drug to increase this good cholesterol, said Rob Yang, Professor from the University of New South Wales in Australia.

Until now, drugs including statins have targeted bad cholesterol (LDL) by inhibiting its synthesis in the liver in an effort to mitigate the risk of heart disease and stroke.

However, while statins are effective at lowering LDL levels, they do little to increase the levels of good cholesterol (HDL) and there is no other drug in use that can significantly boost the human body’s HDL levels.

Up to 90 per cent of a cell’s cholesterol is found at the cell’s plasma membrane, said the study published in the journal Molecular Cell.

“Knowing the molecules that deliver cholesterol to the plasma membrane itself is a huge step forward. The transport of cholesterol to the plasma membrane is the key to the generation of HDL.

If such a drug could be developed, it would not replace statins, but would be used complementarily, with one drug used to reduce the bad cholesterol and the other to increase levels of the good, Yang suggested.

The rampant and uncontrolled growth of cells that characterises cancer could be stopped in its tracks by reducing the amount of cholesterol produced.
