Washington: Researchers have discovered that changes in the gene expression of a key enzyme may contribute to high blood pressure and increase susceptibility to forming blood clots in pregnant women with preeclampsia.

Epigenetics refers to changes in gene expression that are mediated through mechanisms other than changes in the DNA sequence.

The VCU team reported that thromboxane synthase – an important inflammatory enzyme – is increased in the blood vessels of expectant mothers with preeclampsia.The thromboxane synthase gene codes for this enzyme, which is involved in several processes including cardiovascular disease and stroke. This enzyme results in the synthesis of thromboxane, which increases blood pressure and causes blood clots.

Only microscopic amounts of DNA are left on the skeletons, including all the bacteria that lived on the animals. No usable DNA is therefore often found in bone, but mammoth hair is plentiful. Shampooed and bleached and digested, the hair, even at 18,000 years old, can have 90% of the DNA left. The genome shows 4 different "races" of this species. Research has also shown the recreated blood of mammoth. It doesn't decrease its oxygen capacity at the low temperatures the mammoth had to endure. That increased oxygen-offloading ability was one of the essential physiological changes evolved especially for this species, just like the Yuka kidney.

Why having sex really IS the best thing to do

is better for evolution than self-reproduction

Having sex allows us to evolve more effectively than species which reproduce without a partner, according to tests that claim to finally prove the long-held theory.

A video of a group of 14-year-olds smoking shisha pipes in a bar has emerged online, horrifying parents and anti-smoking campaigners.

They want to warn shisha enthusiasts it isn't a safe alternative to cigarettes - smoking a pipe for an hour is the the equivalent of puffing away on 100 cigarettes.

‘Smoke from tobacco contains a number of carcinogens which damage the DNA in cells,’
