Scientists identify mammal model of bladder regeneration

ScienceDaily (Oct. 12, 2012) ? While it is well known that starfish, zebrafish and salamanders can re-grow damaged limbs, scientists understand very little about the regenerative capabilities of mammals. Now, researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine report on the regenerative process that enables rats to re-grow their bladders within eight weeks.

In PLOS ONE, a peer-reviewed, online publication, the scientists characterize this unique model of bladder regeneration with the goal of applying what they learn to human patients.

"A better understanding of the regenerative process at the molecular and cellular level is a key to more rapid progress in applying regenerative medicine to help patients," said George Christ, Ph.D., senior researcher and professor of regenerative medicine at Wake Forest Baptist.

In a previous study by Christ's team, research in rats showed that when about 75 percent of the animals' bladders were removed, they were able to regenerate a complete functional bladder within eight weeks. The current study focused on how the regeneration occurs.

"There is very little data on the mechanisms involved in organ regeneration in mammals," said Christ. "To our knowledge, bladder regeneration holds a unique position -- there is no other mammalian organ capable of this type of regeneration."

The ability of the liver to grow in size when lobes are removed is sometimes referred to as regeneration, but this is a misnomer, said co-author Bryon Petersen, Ph.D., who was a professor of regenerative medicine at Wake Forest Baptist during the period the research occurred. Instead, through a proliferation of cells, the remaining tissue grows to compensate for the lost size. In contrast, the hallmark of true regeneration is following nature's "pattern" to exactly duplicate size, form and function, Petersen said.

"If we can understand the bladder's regenerative process, the hope is that we can prompt the regeneration of other organs and tissues where structure is important -- from the intestine and spinal cord to the heart," said Petersen.

The current study showed that the animals' bodies responded to injury by increasing the rate at which certain cells divided and grew. The most notable proliferative response occurred initially in the urothelium, the layer of tissue that lines the bladder.

As the proliferative activity in the bladder lining waned, it continued elsewhere: in the fibrous band (lamina propria) that separates the bladder lining from the bladder muscles and in the bladder muscle itself.

The researchers have several theories about how the process works, said Christ. One possibility is that cells in the bladder lining transition and become a type of stem cell that can proliferate throughout the bladder. Other theories are that cells in the bladder lining signal other cells to replicate and that injury prompts stem cells to arrive through the blood stream to repair the bladder damage.

In future studies, the scientists will work to identify the exact regenerative process and will expand the work into mice. The ability to breed mice that lack specific genes will enable the team to explore how genes and proteins may affect the regenerative process and possibly help identify therapies to prompt regeneration.

The research was supported by the National Institutes of Diabetes and Digestive and Kidney Diseases under award number R21DK081832.

Co-researchers were Charles C. Peyton, M.D., lead author, David Burmeister, Ph.D., and Karl-Erik Andersson, M.D., Ph.D., of Wake Forest Baptist. Peterson is now at the University of Florida and an adjunct professor at Wake Forest Baptist.

Bizarre alien super-Earth planet probably made of diamond

The alien planet, a so-called 'super-Earth,' is called 55 Cancri e and was discovered in 2004 around a nearby star in our Milky Way galaxy.

By Clara Moskowitz,?SPACE.com / October 11, 2012

The alien planet, a so-called "super-Earth," is called?55 Cancri e?and?was discovered in 2004 around a nearby star in our Milky Way galaxy. After estimating the planet's mass and radius, and studying its host star's composition, scientists now say the rocky world is composed mainly of carbon (in the form of diamond and graphite), as well as iron, silicon carbide, and potentially silicates.

At least a third of the planet's mass is likely pure diamond.

"This is our first glimpse of a rocky world with a fundamentally different chemistry from Earth," lead researcher Nikku Madhusudhan of Yale University said in a statement. "The surface of this planet is likely covered in graphite and diamond rather than water and granite."

55 Cancri e is the first likely "diamond planet" to be identified around a sun-like star, though such worlds have been theorized before. Planets like this are vastly different from our Earth, which has relatively little carbon.

"By contrast, Earth?s interior is rich in oxygen, but extremely poor in carbon ? less than a part in thousand by mass," said study co-author and Yale geophysicist Kanani Lee.

55 Cancri e is what's known as a?super-Earth, with a radius twice as wide as that of our own planet, and a mass eight times greater. It speeds around its host star, making a full orbit in just 18 hours (Earth takes 365 days). It is so close in to the star that its surface temperature reaches a scorching 3,900 degrees Fahrenheit (2,100 degrees Celsius), making it probably way too hot for life. [Oozing Super-Earth: Images of Alien Planet 55 Cancri e]

Previous studies of this planet suggested it might actually be?covered with oozing "supercritical fluids"?? high-pressure liquid-like gases ? seeping out from its rocks. But this idea was based on the assumption that 55 Cancri e had a similar chemical makeup as Earth, Madhusudhan said. The new findings suggest the planet has no water at all.

The revelation of the planet's diamond nature means that it could have very different thermal evolution and plate tectonics processes than Earth, which could create bizarre types of volcanism, seismic activity, and mountain formation. ?

55 Cancri e is one of five planets encircling a sun-like star called 55 Cancri, which lies about 40 light-years from Earth in the constellation of Cancer. This star is so close it is visible to the naked eye in the night sky.

The researchers hope to make follow-up observations of this star system to better determine the star's composition and to analyze 55 Cancri e's atmosphere. This information could bolster the idea that the planet is a diamond world.

A paper reporting the new findings has been accepted for publication in the journal Astrophysical Journal Letters.

Obama, Romney Take Time Off Trail for Debate Prep

WILLIAMSBURG, Va. - President Obama and GOP nominee Mitt Romney are taking time off the campaign trail to prep for Tuesday's presidential debate, a sign of the importance of their second face-off, which comes just three weeks before Election Day.

Obama is spending three days huddled with advisers in the battleground state of Virginia, hunkering down at the luxury Kingsmill Resort along the James River in historic Williamsburg. Romney, meanwhile, is preparing in the Boston area.

After his lackluster showing in Denver, advisers say the president is looking forward to answering questions from the American people in round two, which adopts a town hall format.

"The question is not just which candidate connects with the questioner, but who has the better policies for the American people for the next four years and on that front the president has a great advantage," a senior Obama campaign adviser said.

Over the last two weeks, the Obama campaign has launched more aggressive attacks against Romney, casting him as an extreme conservative trying to reinvent himself as a moderate just weeks before the election.

"Governor Romney has been making pitches all of his life," the adviser said. "He knows how to say what people want to hear, whether that was during his time at Bain [Capital] or during the dozens of town halls he did during the primary."

While both candidates are forgoing campaign events and rallies to study for the debate, both campaigns launched new campaign ads over the weekend.

Blind Chinese activist says nephew could face unfair trial

BEIJING (Reuters) - Blind legal activist Chen Guangcheng said on Saturday that Chinese police had sent the case of his nephew, charged with intentional infliction of injury, to the state prosecutor, paving the way for what he expects will be an unfair trial.

The case of Chen Guangcheng's nephew, Chen Kegui, has renewed international focus on China's human rights and legal system.

Chen has been held incommunicado by police for over five months and has been denied access to his choice of lawyers. His case is widely seen as illegitimate by Chen's family and human rights advocates.

Chen Guangcheng's escape from house arrest in northeastern China in April and subsequent refuge in the U.S. embassy caused huge embarrassment for China, and led to a serious diplomatic rift between the two superpowers.

Chen Kegui was initially charged with "intentional homicide" for using knives to fend off local officials who burst into his home on April 27, the day after they discovered his uncle had escaped.

Chen Guangcheng told Reuters he believed the police downgraded the charge because they had no evidence to build a case of "intentional homicide" against his nephew.

"Judging from the current situation, my confidence in Chen Kegui getting a fair hearing has dropped a lot," Chen Guangcheng said by telephone in New York, where he is now studying law.

Chen Guangcheng said the central government has failed to live up to its promise in May to investigate officials in Shandong whom he accused of engineering the "years of illegal persecution" against him and his family.

"It's been five months, I haven't heard any news about the investigation against Shandong," he said. "Instead I hear that Chen Kegui's case has been sent to the prosecutor, this piece of news in itself is problematic. So how can I not feel that my confidence has been lowered?"

Police in Yinan in Shandong, where Chen Kegui is held in a detention center, were not immediately available for comment.

The prosecutor "almost always accepts the recommendation" made by the police, said Jerome Cohen, an expert in Chinese law from New York University.

"This makes Chen (Kegui)'s prosecution and conviction highly likely," Cohen said in an emailed statement.

Chen Kegui's family-appointed lawyer, Ding Xikui, said he will travel to Yinan next week to see his client, adding that he could not say for certain the maximum sentence that Chen Kegui faces as he has not reviewed the case or seen his client.

The proceedings against Chen Kegui will be a good test case of whether Chinese leaders are intent on enforcing the rule of law and enacting reforms, said Chen Guangcheng.

"I think that if the authorities, at this point, once again don't make the correct choice and once again refuse to safeguard social justice and continue maintaining their own privileges, they are inadvertently announcing to the world: 'You ordinary folk, we just don't want to enforce the rule of law, we want to make hostages out of you ordinary people," Chen said.

After four years in jail on what he and his supporters say were trumped-up charges designed to end his activism, Chen was released in 2010 and put under house arrest in Shandong.

Chen had accused Shandong officials in 2005 of forcing women to have late-term abortions and sterilizations to comply with China's strict family-planning policies. He was charged with whipping up a crowd that disrupted traffic and damaged property.

MooresCloud Light runs Linux, puts LAMP on your lamp (video)

Yes, we'll admit that we borrowed that pun in the title. MooresCloud founder Mark Pesce's Xzibit reference is still a very apt description of the Light, his company's Linux-based LED lamp. The Australian team's box-shaped illumination runs the open OS (including a LAMP web server stack) on an integrated mini PC with an accelerometer and WiFi. The relative power and networking provide obvious advantages for home automation that we've seen elsewhere, but it's the sheer flexibility of a generalized, web-oriented platform that makes the difference: the Light can change colors based on photos or movement, sync light pulses to music and exploit a myriad of other tricks that should result from a future, web-based app store. When and how the Light launches will depend on a Kickstarter campaign to raise $700,000 AUD ($717,621 US) starting on October 16th, although the $99 AUD ($101 US) cost is just low enough that we could see ourselves open-sourcing a little more of the living room. At least, as long as we don't have to recompile our lamp kernel before some evening reading.

Cocktail Thursday: Breaking Bad Edition - Dawg Sports

In 6 years, no one else has filled in for MaconDawg on Cocktail Thursday, and with all the doom and gloom, and the apparent lack of funds for UGA, I thought maybe we needed to branch out like Mr. Heisenberg: get Evil Richt to grow out his goatee and do a little fund raising to get a state of the art baseball facility. I mean, someone had to break bad around here.

After surgery, our favorite go to wide receiver Michael Bennett tweeted, "I feel like a million bucks on these pain meds!" Which I found interesting, as I had told the staff earlier this week if I did Cocktail Thursday, it "maybe the blow, ice and grass with a beer edition". I said this immediately after trying to bring everything down a notch from last Saturday's live thread. After all, sometimes you need real pain relief. Or maybe that stuff is what some folks were on when they lost their mind last weekend. Furthermore, alternative, albeit illegal, recreation has been a pastime of some Georgia players. Hey, maybe we can turn this thing into profit! The Board of Regents and Michael Adams will be thrilled like after Saturday's loss, and we'll get a new baseball park with our ill gotten gains! However, we at DawgSports do not promote or condone the use of illegal drugs or non-prescribed medication*. So we'll have to stick with a tasty and also multi purposed beverage.

Speaking of pain medication, there was the Bayer aspirin commercial back in the 80s that said "When asked, 9 out of 10 Doctors said they would choose Bayer aspirin if stranded on a deserted island." As a young Boy Scout with a survivalist mentality, I asked my Moms, a Registered Nurse, what she would want if stranded on a deserted island. Her answer: A bottle of liquor. She then explained, "It can clean a wound, help start a fire, and well, if you got pain, it can fix that too." Funny the things that stick in a childhood memory, and really, as someone with a lot of survival training, it wasn't a bad answer. We do need a little survival mentality ourselves right now to push through the back half of this football year. So, as I was thinking on this week's concoction, I talked with a psychologist friend of mine, and I learned it has been shown men are usually only taught one form of socially accepted emotional expression: anger.

When you break bad, there is usually a lot of anger involved, and there was a lot of anger being poured out after last Saturday's game. I know. I get it. I feel ya. However, I think what we were really feeling wasn't anger, it was a big sad. In fact, what I think we felt was a Shot Through The Heart. Take a high ball glass and fill it with ice. Pour in 2 ounces of high test pure grain liquor, like Everclear. Fill the glass with Passion Fruit juice, and then drizzle in about ? oz of grenadine. Stir and garnish with a who cares. You could pour this in a cocktail shaker and give it just one shake, but why bother with all the extra execution? Execution is overrated anyways. We'll have to work on our advanced execution next week while this week we work on fundamentals (of the blocking and tackling variety). Why Everclear? Because you drank all that high dollar bourbon last week, don't lie to me, the cabinet is getting bare, your pocket is thin with all the bets you lost, and it would make a great choice for your survival pack. It's probably what those yahoos were drinking when they got stupid at Aaron Murray's crib last week. Passion fruit juice? That's subterfuge, required in all breaking bad activities, and to trick yourself into thinking it's something it's not, like full of energy, vim and vigor. Maybe it will give us the boost we need; something has got to do it after all. And why grenadine? Well, that's the last crap laying around in your cabinet now back from that time you thought Tequila Sunrises were a cool drink. It will also be a way of making your guests think you're making a real tropical beverage. Which you're not. You're just killing the pain with 180 proof. **

In the meantime, feel free to use this as an open thread to discuss anything you want, particularly just how bad tonight's games are. Or anything else that suits you. Until next week...

GO DAWGS!
