New materials may help prevent infections by blocking initial bacterial attachment

ScienceDaily (Oct. 26, 2012) ? Bacteria's ability to cling to virtually any surface is a vexing problem in the medical community. Engineering a surface that can easily slough off these dangerous bugs has, until recently, had limited success. Recently, however, a team of British researchers has discovered a new class of materials that resists bacterial attachment. Now these scientists from the University of Nottingham, U.K., are ready to set out on the approval process that will take their research to the clinical testing stage, paving the way for medical applications.

The researchers will present their findings at the AVS 59th International Symposium and Exhibition, held Oct. 28 -- Nov. 2, in Tampa, Fla.

To date, scientists have been unable to fully explain how bacteria are able to adhere so durably to virtually any surface. Despite this limited understanding of bacteria-material interactions, the Nottingham researchers were able to screen thousands of different chemical combinations for resistance to bacterial adhesion. The studies revealed that one particular class of compounds, acrylates with hydrophobic groups, proved highly resistant to bacteria's sticky tendencies.

"The new materials are to bacteria what non-stick cookware is to food," said Andrew Hook, a researcher at the Nottingham School of Pharmacy. "Bacteria can stick to the surface of [traditional] medical devices and form a community, known as a biofilm, where the bacteria become highly resistant to antibiotics and the immune system."

By preventing the biofilm from forming on devices in service, the new materials help the immune system to simply eliminate the bacteria as if the device had never been inserted. In contrast, current antibacterial materials, like silver, actually kill bacteria.

After the new non-stick materials were identified, they were successfully tested on surfaces in the laboratory and on standard medical devices, such as catheters, within an animal model. In laboratory studies of the new materials, the researchers found a 96.7-percent reduction in bacterial coverage compared to commercially available silver-containing catheters for the bacterium Staphylococcus aureus.

By coating medical devices with the optimal polymer composition of one of this class of acrylates, for example the compound tricyclodecane-dimethanol diacrylate that the researchers tested, scientists believe they can prevent bacteria from attaching and also prevent associated infections, which could reduce health care costs.

The researchers are now ready to take their research to the next level and prepare the regulatory package to begin clinical trials. They hope the trials will show that by denying bacteria a foothold on medical equipment in humans, the chances of a patient contracting a medical device-associated infection are much lower.

Nottingham pharmacy professor Morgan Alexander hopes that since no antibiotics are used this will lead to a method to reduce infections from bacteria without the risk of antibiotic resistance developing. "The challenge now is to have materials recognized by the medical device industry," Alexander said. "That would allow us to develop products for specific applications. There's a lot of potential to improve human health, but we need to prove that."

The researchers are in discussions with potential partners to develop coated devices and are hopeful their material could reach the market in 5 to 10 years.

What happened to the gender gap?

WASHINGTON (AP) ? What gender gap?

Less than two weeks out from Election Day, Republican Mitt Romney has erased President Barack Obama's 16-point advantage among women, a new Associated Press-GfK poll shows. And the president, in turn, has largely eliminated Romney's edge among men.

Those churning gender dynamics leave the presidential race still a virtual dead heat, with Romney favored by 47 percent of likely voters and Obama by 45 percent, a result within the poll's margin of sampling error, the survey shows.

After a commanding first debate performance and a generally good month, Romney has gained ground with Americans on a number of important fronts, including their confidence in how he would handle the economy and their impressions of his ability to understand their problems.

At the same time, expectations that Obama will be re-elected have slipped: Half of voters now expect the president to win a second term, down from 55 percent a month earlier.

For all of the good news for Republicans, however, what matters most in the election endgame is Romney's standing in the handful of states whose electoral votes still are up for grabs. And polls in a number of those battleground states still appear to favor Obama.

As the election nears, Romney has been playing down social issues and trying to project a more moderate stance on matters such as abortion in an effort to court female voters. The AP-GfK poll, taken Friday through Tuesday, shows Romney pulling even with Obama among women at 47-47 after lagging by 16 points a month earlier.

But now his campaign is grappling with the fallout from a comment by a Romney-endorsed Senate candidate in Indiana, who said that when a woman becomes pregnant during a rape "that's something God intended."

Romney quickly distanced himself from the remark by Republican Richard Mourdock. But Obama campaign spokeswoman Jen Psaki said the incident was "a reminder that a Republican Congress working with a Republican President Mitt Romney would feel that women should not be able to make choices about their own health care."

A renewed focus on social issues would be an unwelcome development for Romney: Among female likely voters, 55 percent say Obama would make the right decisions on women's issues, compared with 41 percent who think Romney would.

Romney's pitch to women has been focused squarely on the economy, making the case that what women want most is to ensure their families and their country are on a solid financial footing. The poll shows that message appears to be taking root.

A month ago, women favored Obama over Romney on the economy 56 percent to 40 percent. Now, the split has shifted to 49 percent for Romney and 45 percent for Obama.

Similarly, Obama's lead among women as the candidate who better understands the people's problems has narrowed considerably, from a 58-36 Obama advantage last month to a 50-43 Obama edge now.

Monica Jensen, a 55-year-old independent from Mobile, Ala., says she voted for Obama in 2008 but will shift her vote to Romney this time, largely because of the economy.

"I'm ready for a change," she said. "I want to see the economy go in a different direction."

Ginny Lewis, a Democrat and 72-year-old retired district attorney from Princeton, Ky., says she'll vote for Romney because "I'm tired of the Republicans blaming all the debt on Democrats, so let them take over and see what they do."

Not that she's optimistic about how that will turn out, though. "I think things will get worse before they get better," she said.

Lindsey Hornbaker, a 25-year-old graduate student and nanny, hasn't been swayed by Romney's charm offensive.

Hornbaker, interviewed Wednesday in Davenport, Iowa, where she was attending an Obama rally, said Romney can tweak his tone but not what she sees as a record focused far more on top income earners and out of touch with most working families.

"I heard him go out of his way to sound so moderate during the debate," she said. "And I thought: 'Who is this? Where did this come from?' He may sound like he's focused on the middle class. But where's the record?"

Obama, meanwhile, has been working to shore up his support among men, who tend to be more Republican than women. In the 2008 election, men broke 49 percent for Obama to 48 percent for John McCain, even though Obama got 53 percent of the vote overall. The president's job approval ratings among men have tended to fall below his ratings among women throughout his first term.

A month ago, Romney's advantage among men was 13 percentage points. Now, it's down to 5 points, with most of the shift toward Obama coming among unmarried men.

Obama's election chances hinge on turning out voters like Jon Gerton, a disabled construction worker from Jonesboro, Ark. Gerton's a staunch Obama supporter ? but he didn't vote in 2008.

"It takes longer than four years to get things to the point where things are going better," Gerton said. "Four years, it's not very long."

There has been a gender gap in every presidential election since 1980. In 2008, women were 7 percentage points more likely than men to vote for Obama.

Overall, people are significantly more optimistic about the economy and unemployment in the coming year than they have been at any point in AP-GfK polling going back to March 2011, when the poll first started asking those questions. And likely voters are even more optimistic than other adults.

Nearly six in 10 likely voters think the economy will improve in the next year, up from 46 percent last month. And 42 percent think the number of unemployed Americans will drop in the next year, up from 32 percent in September.

Count Chrysta Walker, of Cedar Lake, Ind., among the voters who are sticking with Obama because they think he's got the right solutions for the fragile economy.

"He's got the middle class at heart," says the 58-year-old Walker. On the economy, she says, Obama "did as well as could be expected because he didn't get a lot of cooperation."

David Bierwirth, who owns an autograph sales business in Las Vegas, turned out at a Romney rally in Henderson this week to show his support for the GOP nominee. To Bierwirth, his vote for Romney is all about the economy.

"I want people back to work," he says, "because then they will buy my products."

The Associated Press-GfK poll was conducted Oct. 19-23 by GfK Roper Public Affairs & Corporate Communications. It involved landline and cellphone interviews with 1,186 adults nationwide, including 839 likely voters. Results for the full sample have a margin of sampling error of plus or minus 3.5 percentage points; for likely voters it is 4.2 points.

New vitamin-based treatment that could reduce muscle degeneration in muscular dystrophy

New vitamin-based treatment that could reduce muscle degeneration in muscular dystrophy

Wednesday, October 24, 2012

Boosting the activity of a vitamin-sensitive cell adhesion pathway has the potential to counteract the muscle degeneration and reduced mobility caused by muscular dystrophies, according to a research team led by scientists at the University of Maine.

The discovery, published 23 October in the open access journal PLOS Biology, is particularly important for congenital muscular dystrophies, which are progressive, debilitating and often lethal diseases that currently remain without cure. The researchers found that they could improve muscle structure and function in a zebrafish version of muscular dystrophy by supplying a common cellular chemical (or its precursor, vitamin B3) to activate a cell adhesion pathway.

Muscle cells are in themselves relatively delicate, but derive important additional mechanical strength from adhesion protein complexes; these anchor the muscle cells to an external framework known as the basement membrane, thereby helping to buffer the cells against the extreme forces that they experience during muscle contractions. Mutations in the genes that encode these adhesion proteins can weaken these attachments, making muscle cells more susceptible to damage and death.

The resulting muscle degeneration can eventually lead to progressive muscle-wasting diseases, such as muscular dystrophies. A major component of the basement membrane, a protein called laminin, binds to multiple different receptors on the muscle cell surface and forms a dense, organized network.

The study was led by UMaine Associate Professor of Biological Sciences, Clarissa Henry, whose laboratory focuses on understanding how cell adhesion complexes contribute to muscle development. The researchers discovered that a pathway involving a common cellular chemical called nicotinamide adenine dinucleotide (NAD+) plays a role in the formation of organized basement membranes in muscle tissue, during development of the fish embryo. As disordered basement membranes are seen in many different types of muscular dystrophies, the researchers wondered whether activating this pathway might reduce the severity of some muscular dystrophies.

In the current study, the researchers show that NAD+ improves the organization of laminin in a zebrafish version of muscular dystrophy. Zebrafish lacking either of the two main receptors for laminin have a disorganized basement membrane, causing muscle degeneration and difficulties with movement. However adding extra NAD+, or even a vitamin packet containing vitamin B3 (niacin, a precursor to NAD+), significantly reduced these symptoms.

The research team found that the main protective effects of NAD+ come from enhancing the organization of the laminin structure in the basement membrane, which helps to increase the resilience of diseased muscle fibers.

Because the same cell adhesion complexes are found in humans, the research team is optimistic that these findings may one day positively impact patients with muscular dystrophies. "Although there is a long way to go, I'm hopeful that our data could eventually lead to new adjuvant therapies," says University of Maine Ph.D. student Michelle Goody, who led the research team with Prof. Henry.

Prof. Henry summarizes; "One of my favorite aspects of this study is that it is a poster child for how asking basic biological questions can lead to exciting discoveries that may have future therapeutic potential."

(AP) ? A suburban New York City police officer killed after being shot in what started out as a traffic stop was an "exemplary officer," a county official said Wednesday, as he acknowledged the death of the civilian had been overshadowed by the outpouring of grief for the officer.

Nassau County Officer Arthur Lopez was killed Tuesday after getting shot in what had started out as a traffic stop near the Belmont Park racetrack. Ex-convict Darrell Fuller, 33, was arrested on charges of shooting him as well as another driver, 52-year-old Queens resident Raymond Facey, in a subsequent carjacking.

Nassau County Executive Edward Mangano called Lopez, an 8-year veteran on the force, "an exemplary officer, a real heroic officer."

"His file is full of commendations," Mangano said on Fox 5 News Wednesday morning.

Lopez, 29, was on patrol Tuesday in Bellerose Terrace, a community at the border of New York City's Queens borough and Nassau County. The officer and his partner spotted a damaged silver Honda that was "running on rims," suspecting it was wanted for leaving the scene of a hit-and-run accident, authorities said.

The officers followed the car, and it pulled over. There was "a brief exchange of words" between Lopez and the driver before the driver left the vehicle and fired one round into Lopez's chest, police Chief Steven Skrynecki said, adding that the officer wasn't wearing a bulletproof vest.

Mangano said Nassau does not have a mandatory bullet-proof vest policy, saying "it's up to each police officer."

"The shrieks of his mother will haunt me and all those who were present forever," said Mangano, who visited the family after the shootings. "A mother doesn't want to live when she loses a son."

He said he had not yet visited Facey's family. "I know it's been overshadowed" by Lopez's murder but "we're equally shocked and dismayed that such an act would take place in New York, on Long Island. It's terrible."

The second officer administered first aid to Lopez, officials said, and was later hospitalized for trauma.

The shooter got back into his car and drove away, and then accosted Facey, authorities said. He shot the Queens man in the head, dragged him out of his car and left him dead on the roadway as he drove away, they said. The car later was found abandoned in a residential neighborhood in Queens.

The slayings touched off a search for Fuller that included heavily armed New York Police Department officers going door-to-door in Queens. Authorities also closed the Cross Island Parkway for several hours, causing traffic delays.

A 911 caller reported hearing gunfire in Queens amid the massive manhunt for Fuller. Responding officers found him in a vehicle ? not the one carjacked ? with what appeared to be a self-inflicted gunshot wound.

Fuller was hospitalized in police custody for treatment of an undisclosed wound. It was unclear if he had a lawyer.

Fuller had served four years in prison after pleading guilty to attempted murder in 2005, authorities said. He was jailed again in 2010 after violating his parole, but was released in May 2011.

"We're endeavoring to find out what triggered this entire series of events," Skrynecki said while announcing the arrest late Tuesday.

Before the shootings, Fuller left a hospital and had gotten in a car accident, the chief added, but wouldn't elaborate.

"It's absolutely shocking that a man who committed attempted murder only did 5 years, got back on the streets, arrested again and out of jail again," said Mangano. "Whoever let him out on a parole, it's ridiculous ... outrageous."

A man who witnessed the officer's shooting as he was stopped at a gas station along the highway said it looked like a routine traffic stop.

"The officer's walking up to the car. They just pulled out (a gun) and shot," said Paul Walcott, a music producer from the Queens neighborhood of Bayside. "He went right down. He got hit point blank. He went straight down."

The car then sped off, heading south on the Cross Island Parkway, a north-south highway along the border of Queens and Nassau County.

"In broad daylight, this time of day, it was incredible to see something like that," Walcott said.

The shooting unfolded within blocks of Belmont Park, the racetrack where the Belmont Stakes is held.
