Новые преимущества пуповинной крови перед костным мозгом

Открытие ученых из Пенсильванского университета и Дрезденского технического университета указывает на необходимость пересмотра правил подбора доноров костного мозга, поскольку их биоматериал может повышать у реципиента риски воспалительных заболеваний в будущем.

Ученые давно знали, что, например, воспалительное заболевание кишечника – колит – повышает вероятность развития воспаления десен и наоборот. Эта тенденция прослеживается для многих воспалительных заболеваний, однако до сих пор ни один механизм не мог объяснить данную двунаправленную связь. Теперь исследователи установили, что источник проблем кроется в костном мозге.

Оказалось, что после воспаления клетки-предшественники в костном мозге запоминают это событие - в них происходят важные эпигенетические изменения, связанные с известными признаками воспалительной реакции.

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
