May 12, 2013 ? From microscopes to MRI scanners, imaging technology is growing ever more vital in the world's hospitals, whether for the diagnosis of illness or for research into new cures. Imaging technology requires dyes or contrast agents of some sort. Current contrast agents and dyes are expensive, difficult to work with and far from ideal. Now, Danish chemists have discovered a new dye and proved its worth against any of the dyes currently available.
Thomas Just S?rensen and Bo Wegge Laursen are chemists at the University of Copenhagen, Denmark. In a series of publications, they have shown that the aza-oxa-trangulenium dyes have the potential to outperform all fluorescent dyes currently used in imaging.
"Our dyes are ten times better, far cheaper and easier to use. The latter I believe, will lead to expanded opportunities and broadened use, by physicians and researchers in developing countries, for example." Says Thomas Just S?rensen.
Visual noise blocks correct diagnosis
It might seem odd, but one of the central challenges when taking pictures of cells and organs, is to avoid noise. The agents that make it possible to see microscopic biological structures are luminescent, but then, so is tissue. Consequently, the contrast agent's light risks being overpowered by "light noise." Just as the dial and hands of a watch might glow-in-the-dark, tissue becomes luminescent when exposed to light. Tissue and other organic structures luminesce, or lights up, for 10 nanoseconds after exposure to light. The light-life of an ordinary dye is the same -- 10 nanoseconds. But triangulenium dyes produce light for an entire 100 nanoseconds.
The long life of the triangulenium dyes means that an image can be produced without background noise. Furthermore, the extra 90 nanoseconds opens the possibility of filming living images of the processes occurring within cells, for example when a drug attacks an illness.
Neither expensive, nor difficult or technically demanding
Medical image analysis departments currently devote an incredible amount of time to staining samples, because all samples must be treated with two agents. The use of triangulenium dyes necessitates only one dye. And in contrast with typical dyes, no specialized equipment is needed to see the dyes in tissue samples. A lens from a pair of polarized sunglasses and an ordinary microscope are all that are required.
Open Source dye despite obvious competitiveness
When one compares the advantages of triangulenium dyes against the three million Danish kroner per gram price tag of traditional dyes,(500.000$US)(320.000?) you would expect that the new dye would immediately out-compete its predecessors. However, up to now S?rensen and Laursen have had to give their dye away. "I know that our dye is better, but biologists and physicians don't. Therefore, we are giving the dye away to anyone that wants to perform a comparison test. Someone who needs to assess the health of sick people wouldn't dare to rely on an untested substance. Only when several researchers have shown triangulenium dyes to perform just as effectively as its predecessors can we hope for our substance to become more widely adopted," concludes Thomas Just S?rensen.

CAIRO (AP) ? In his first comments to the media since he was detained more than two years ago, Egypt's ousted leader Hosni Mubarak said he is dismayed at the country's state of affairs and particularly the plight of the poor.
The 85-year old Mubarak said in remarks published Sunday in Al-Watan newspaper that it is also too early to judge his elected successor, Islamist President Mohammed Morsi, because he has a heavy burden to deal with. He also warned against a much-negotiated loan from the International Monetary Fund, saying it would make life harder for the poor in Egypt, where over 40 percent of the population lives on less than $2 a day.
The authenticity of the interview could not be immediately verified. Calls by The Associated Press to Mubarak's lawyer Farid ElDeeb went unanswered, but he was quoted as telling Ahram Online, the electronic version of the state-owned Al-Ahram, that the interview was a "fabrication."
Al-Watan's reporter, Mohammed el-Sheik, took photos of himself near and inside Mubarak's medical helicopter, without the ex-leader inside. El-Sheik said he conducted the interview after sneaking into a waiting area where Mubarak was held during his trial Saturday, apparently before the hearing began.
He also told the private ONTV station Sunday that he couldn't record the interview because he had to avoid Mubarak's tight security.
Mubarak has been a longtime nemesis of the Muslim Brotherhood, the Islamist group from which Morsi hails. In his comments to the privately owned Egyptian paper published Sunday, Mubarak appeared to be gloating, painting a picture of a nation that has unraveled following his 2011 ouster and portraying himself as a protector of the poor.
Mubarak stepped down in February 2011 in the face of a wave of popular protests whose main slogan was "Bread, Freedom and Social Justice." Protesters accused Mubarak of fostering a culture where power was centralized and police acted with impunity. They also believed Mubarak was grooming one of his sons to succeed him.
Mubarak's comments to Al-Watan also appeared to be addressing a growing segment of the population which has grown nostalgic for Mubarak's days amid continuing turmoil in the two years since his ouster. The country has been plagued by tenuous security and an enduring standoff between Morsi's Brotherhood and its Islamist allies and the largely secular opposition, which launched the 2011 revolt but failed to make political gains since.
Mubarak told the newspaper reporter he was "very, very sad" for impoverished Egyptians. He said he was also dismayed by the state of the economy, the industrial cities built during his nearly 30 years in office, and the country's lack of security.
The comments were Mubarak's first to be directly made to a reporter since his ouster, and his first public statements since his captivity. They came after a hearing in his retrial for his role in the killing over 800 protesters during the popular uprising. At the trial, Mubarak appeared in the dock on a hospital gurney, alongside his two sons. The trial was adjourned for June 8.
Mubarak was detained two years ago and put on trial on the same charges. He has since been hospitalized, sentenced to life in prison, had his sentence overturned and then granted a retrial.
The first Arab leader to be put on trial by his own people, Mubarak is also facing corruption charges in separate cases, where prosecutors are investigating his family wealth amid claims he amassed a massive fortune while in power. His two sons are also on trial on corruption charges.
In his comments, Mubarak also said he feared for the country's future and its poor should tough economic measures be imposed in order to acquire a $4.8 billion loan from the IMF. Egypt's economy took a hard hit over the last two years as foreign reserves dwindled, foreign investment sharply declined and tourists largely stayed away amid political turmoil.
Morsi's government would have to impose likely unpopular austerity measures as part of an economic reform program it is currently negotiating with the IMF. But talks have dragged on, while politics remain deeply polarized and consensus on managing the country's affairs is elusive.
Mubarak also said he is certain future generations will view his legacy fairly and that history will "exonerate" him.
Mubarak's last public comments were in April 2011, just before he was detained. At the time, Saudi-owned Al-Arabiya TV station aired a prerecorded audiotape by Mubarak, in which he emotionally denied he used his position to amass wealth.
Also on Sunday, Egypt's highest appeal court granted a Mubarak-era steel magnate a retrial in one of a number of cases he is facing. Ahmed Ezz, who has been handed a combined 54 years of prison sentences and fined billions of dollars, will be retried on charges of money laundering in which he previously received a seven-year prison sentence and fined nearly $3 billion.
Ezz has received the heaviest penalties yet in the slew of trials against former regime officials. Many of Mubarak's government ministers have either been freed, or are still on trial.
Some have entered into talks with Morsi's cash-strapped government.
On Sunday, Mubarak's former Trade Minister Rachid Mohammed Rachid was taken off an arrest list and his assets unfrozen by the attorney general.
Rachid, who was in Dubai during the 2011 uprising and has not returned, was sentenced to 15 years in prison and ordered to pay more than $200 million for approving production licenses to steel magnate Ezz without auctioning them publicly. In a separate case, Rachid was convicted of squandering public funds and sentenced in absentia to five years in prison and ordered to pay nearly $800,000.
It was not immediately clear how much Rachid paid to settle with the government.

Astronaut helmet camera captures video of NASA engineers Chris Cassidy and Tom Marshburn replacing a pump on International Space Station suspected of leaking ammonia.
By Tariq Malik, Space.com
Two spacewalking astronauts may have fixed an ammonia leak outside the International Space Station on Saturday, perhaps bringing the outpost's vital cooling system back up to full strength.
Clad in bulky spacesuits, NASA astronauts Chris Cassidy and Tom Marshburn replaced a pump control box thought to be responsible for the?leak of ammonia, which cools down the orbiting lab's systems. It looks like this fix did the trick, as no ammonia flakes were seen streaming into space when Mission Control turned on the newly installed gear.
"We're not seeing anything," Cassidy said at around 12:35 p.m. ET, several minutes after the pump was turned on. "No snow." [Emergency Spacewalk to Fix Space Station Leak in Photos]
NASA officials stopped short of declaring total victory, however, saying that time will tell if the fix holds.
"It will take some diagnostics, still, over the course of the next several days by the thermal systems specialists to fully determine that we have solved the problem of the?ammonia leak,"?NASA spokesperson Rob Navias?said during live mission commentary. "But so far, so good."?
An emergency spacewalk?
Cassidy and Marshburn floated outside the space station at 8:44 a.m. ET Saturday, beginning what officials described as a six-hour detective's investigation to find ? and hopefully fix ? the ammonia leak.
Cassidy, who led the spacewalk, reported seeing "no smoking gun" as he and Marshburn began their inspection of the old ammonia pump control box, one of several on the space station's far left segment, known as the Port 6 truss. It is part of the cooling system for the two wing-like solar arrays extending from the Port 6 segment.
Upon removing the box, the spacewalkers still saw no signs of ammonia flakes.
"It looks really, really clean, surprisingly so," Cassidy said while peering deep inside the box using what looked like a dentist's mirror.

Flakes of ammonia were discovered leaking out of the cooling system on International Space Station, and two astronauts are taking a spacewalk to repair it. NBC's Tom Costello reports.
The ammonia leak was first spotted by space station astronauts last Thursday, when the crew reported seeing flakes of frozen coolant floating outside. They recorded video of the ammonia leak and sent it down to Mission Control for analysis.
While the leak posed no danger to the space station's crew, it could have impacted the amount of power available for daily operations on the orbiting laboratory if left unchecked, NASA officials said. So Cassidy and Marshburn were sent out on an emergency spacewalk to attempt a fix.
The roughly 48-hour turnaround made this the?fastest spacewalk plan of its kind?ever devised for a space station crew, mission managers have said.
By about 1:00 p.m. EDT (1700 GMT), a little more than four hours into the spacewalk, Cassidy and Marshburn were getting ready to head back to a space station airlock, where they must clean their spacesuits to make sure they don't bring any toxic ammonia into the orbiting lab.
A history of ammonia leaks
This is not the first time astronauts have had to tackle ammonia leaks in the?space station's cooling system?during a spacewalk.
Last year, astronauts Sunita Williams of NASA and Akihiko Hoshide of Japan performed a spacewalk to fix a leak that was also found on the Port 6 truss. That ammonia leak was in the same coolant loop as the current leak, but engineers do not yet know if the two leaks are related.
The station's Port 6 truss is the oldest piece of the space station's scaffolding-like backbone and carries two of the outpost's eight wing-like solar arrays. It launched in November 2000 and was originally installed on the station's roof, towering over the orbiting lap. In 2007, visiting shuttle astronauts relocated the P6 truss to its final location on the station's far left side.
This was the fourth spacewalk for both Marshburn and Cassidy, and the 168th total to support space station assembly and maintenance. Inside the?International Space Station, commander Chris Hadfield of Canada and Russian cosmonauts Roman Romanenko, Alexander Misurkin and Pavel Vinogradov followed the spacewalkers' progress.
Today's spacewalk comes just two days before Hadfield, Marshburn and Romanenko are due to return to Earth to end their five-month mission in space.
The three men are due to leave the space station on Monday and land on the steppes of Kazakhstan in Central Asia. Those plans are still going forward, space station mission managers said.

ANKARA, Turkey (AP) ? Two car bombs exploded in a Turkish town near the border with Syria on Saturday, killing around 40 people and wounding 100 others, officials said. Turkey's deputy prime minister said Syria's intelligence and military were "the usual suspects" behind the bombings, but said authorities were still investigating the attacks.
The blasts, which were 15 minutes apart, raised fears that Syria's brutal civil war violence was crossing into its neighbor.
One of the car bombs exploded outside the city hall while the other went off outside the post office in the town of Reyhanli, a main hub for Syrian refugees and rebel activity in Turkey's Hatay province, just across the border. Images showed people frantically carrying victims through the rubble-strewn streets to safety.
Deputy Prime Minister Bulent Arinc said about 40 people were killed and 100 others wounded in the blasts and linked them to Syria. There was no immediate information on the identities or nationalities of the victims.
"We know that the Syrian refugees have become a target of the Syrian regime," he said. "Reyhanli was not chosen by coincidence."
"Our thoughts are that their mukhabarat (Syrian intelligence agency) and armed organizations are the usual suspects in planning and the carrying out of such devilish plans," he said.
Arinc said Turkey would "do whatever is necessary" if proven that Syria is behind the attack.
Prime Minister Recep Tayyip Erdogan earlier also raised the possibility that the bombings may be related to Turkey's peace talks with Kurdish rebels meant to end a nearly 30-year-old conflict.
Syrian mortar rounds have fallen over the border before, but if the explosion turns out to be linked to Syria it would be by far the biggest death toll in Turkey related to its neighbor's civil war.
Syria shares a more than 500-mile border with Turkey, which has been a crucial supporter of the Syrian rebel cause. Ankara has allowed its territory to be used as a logistics base and staging center for Syrian insurgents.
Foreign Minister Ahmet Davutoglu vowed from Berlin that Turkey would act.
"Those who for whatever reason attempt to bring the external chaos into our country will get a response," he said.
The main Syrian opposition group, the Syrian National Coalition, condemned the "terrorist attacks" in Reyhanli, saying it stands together with the "Turkish government and the friendly Turkish people."
The coalition sees "these heinous terrorist acts as an attempt to take revenge on the Turkish people and punish them for their honorable support for the Syrian people," it said.
Reyhanli is a center for aid and alleged weapon trafficking between Turkey and Syria, as well as for Syrian rebel activity. Apart from refugees living in camps, many Syrians escaping the civil war have also rented houses in the town.
The explosions came days before Erdogan is scheduled to travel to the U.S. for talks, which are expected to be dominated by the situation in Syria.
"This ... will increase the pressure on the U.S. president next week to do something to show support to Turkey when Erdogan visits him in Washington," said Soner Cagaptay, an expert on Turkey at the Washington Institute. "Washington will be forced to take a more pro-active position on Syria, at least in rhetoric, whether or not there is appetite for such a position here."
Abdullah, a Reyhanli resident, told The Associated Press he heard two strong explosions at about 1 p.m. "The bombs were very powerful," he said by telephone.
The frontier area has seen heavy fighting between rebels and the Syrian regime. In February, a car bomb exploded at a border crossing with Turkey in Syria's Idlib province, killing 14. Turkey's interior minister has blamed Syria's intelligence agencies and its army for involvement.
Four Syrians and a Turk are in custody in connection with the Feb. 11 attack at the Bab al-Hawa frontier post. No one has claimed responsibility, but a Syrian opposition faction accused the Syrian government of the bombing, saying it narrowly missed 13 leaders of the group.
In that bombing, most of the victims were Syrians who had been waiting in an area straddling the frontier for processing to enter Turkey.
Tensions flared between the Syrian regime and Turkey after shells fired from Syria landed on the Turkish side, prompting Germany, the Netherlands and the U.S. to send two batteries of Patriot air defense missiles each to protect their NATO ally.
