Two allies of Tunisia’s Ben Ali ‘detained’

Tunisian police have detained two politicians close to ousted President Zine al-Abidine Ben Ali, state media report.

Mr Ben Ali’s former adviser Abdelaziz bin Dhia and former Interior Minister and head of Senate Abdallah Qallal were now under house arrest, they said.

The news came as a new protest march against the interim government reached the capital Tunis.

Protesters want the prime minister, who served under Mr Ben Ali, to resign.

PM Mohamed Ghannouchi has pledged to quit after elections, which are expected within six months.

Tunisia’s state media announced the arrests of the two political allies of the former president on Sunday, without providing further details.

The media also said that the police were searching for Abdelwahhab Abdalla – another former adviser to Mr Ben Ali.

Last week, some 33 members of Mr Ben Ali’s were arrested as they tried to leave the country.

State TV showed what it said was gold and jewellery found during raids on the their properties.

It is not known which family members of Mr Ben Ali – who has fled to Saudi Arabia – have been held.

On Sunday, a new protest march reached Tunis.

Some 1,000 demonstrators from Menzel Bouzaiane – the rural area where protests against Tunisia’s authoritarian rule began in December – had joined the “Caravan of Liberation” to the capital.

The main trade union, the General Tunisian Workers’ Union (UGTT), has backed the protest, which set off on Saturday.

“The aim of this caravan is to make the government fall,” said Rabia Slimane, a teacher taking part in the caravan protest.

Mr Ghannouchi has left Mr Ben Ali’s ruling Democratic Constitutional Rally (RCD) party and insisted that figures from the previous regime who have remained in positions of power – including the ministers of defence, interior, finance and foreign affairs – have “clean hands”.

But this has failed to satisfy many opposition figures and protesters.

On Saturday, policemen – who had defended the regime of the ousted president – were among those protesting, which the BBC’s Magdi Abdelhadi in the Tunisian capital says marked a very dramatic development.

The official death toll during the unrest leading to Mr Ben Ali’s flight was 78, though the UN says more than 100 people died. Authorities have promised to investigate the deaths of protesters.

A final day of mourning is being observed on Sunday for those killed.

There is speculation that the Tunisian unrest – which has been driven by economic grievances and resentment about political repression – could spread to other countries.

In Algeria, police broke up an anti-government demonstration on Saturday by about 300 protesters calling for greater freedoms. There were also protests in Yemen against the rule of President Ali Abdullah Saleh.

A 32-year-old Dutch national is due in court charged with murdering landscape architect Jo Yeates.

Engineer Vincent Tabak, who was arrested on Thursday, is due at Bristol Magistrates’ Court on Monday.

Miss Yeates, 25, was found dead on Christmas Day, eight days after going missing from her home in the Clifton area of Bristol.

Her body was found next to a country road in Failand, three miles from where she lived.

A post-mortem examination revealed she had been strangled.

Miss Yeates, who was originally from Ampfield in Hampshire, was reported missing by her 27-year-old boyfriend Greg Reardon on 19 December when he returned to their home after a weekend away visiting family in Sheffield.

She disappeared on 17 December after going for Christmas drinks with colleagues at her architectural firm.

Mr Tabak lived next door to Miss Yeates on Canynge Road.

Key to severe strokes ‘uncovered’

One reason why people with diabetes can suffer more damage during strokes has been discovered by US scientists.

The study on rats, published in Nature Medicine, found a protein which increased bleeding when blood sugar levels are high.

Elevated sugar levels have been linked to at least one in ten strokes.

Diabetes UK said the big test was whether the research would lead to clinical benefits for people with high sugar levels.

It is thought that 150,000 people in the UK have a stroke each year, more than a third die as a result.

There are two main types, 80% are caused by blood clots in the brain (ischaemic stroke) and 20% when blood vessels bleed into the brain (haemorrhagic stroke).

More than half of people with haemorrhagic strokes have high levels of sugar in the blood.

“Rapid control of blood sugar levels may provide an opportunity to reduce intracerebral haemorrhage”

Dr Edward Feener Joslin Diabetes Centre

The haemorrhages also seem to be more severe, forming over a larger area of the brain, causing more damage and increasing the risk of death.

Scientists at the Joslin Diabetes Centre injected blood into the brains of rats with and without diabetes.

The bleeding was ten times greater in those with diabetes than in healthy rats.

The group then studied the impact of a protein, plasma kallikrein, which had already been linked to sight problems in diabetics.

The researchers found that a combination of high blood sugar and plasma kallikrein resulted in increased bleeding.

They believe plasma kallikrein slows clotting when there is lots of sugar in the blood, although the exact mechanism remains unclear.

Dr Edward Feener, who led the study, said: “Given the prevalence of strokes and the damage they inflict, these findings are exciting because they suggest the possibility that rapid control of blood sugar levels may provide an opportunity to reduce intracerebral haemorrhage, which is a clinical situation that has very limited treatment options.

“This work could have broad implications since about half of patients with acute haemorrhagic stroke have hyperglycemia, whether or not that have pre-existing diabetes.”

Dr Sharlin Ahmed, research liaison officer at The Stroke Association, said: “Diabetes is known to increase a person’s risk of stroke, and research has shown that strokes caused by a bleed in the brain are more severe in people with diabetes as a result of poorly controlled blood sugar levels.

“Controlling glucose levels is vital if you have diabetes. This research not only provides further evidence that glucose control can reduce your risk of stroke, but it also suggests that it could reduce the severity of a stroke caused by a bleed in the brain.

“However, it is very early days and much more research needs to be carried out before human trials are undertaken.”

Dr Iain Frame, director of research at Diabetes UK, said: “This early research has made an interesting discovery into how high blood glucose levels interact with certain chemicals in the blood, and with the damage caused by stroke.

“As the authors admit, however, there are limitations in the animal model they used so their results do not reflect what happens to the human brain when it haemorrhages.

“Much more research is needed to test how we might be able to use this knowledge to limit this stroke damage and that will prove to be the big test as to whether this study will lead to any benefits for people with high glucose levels who have a stroke.”
