Bombings Are Said to Kill Dozens Near Syria’s Capital

Rebels celebrated on top of a downed Syrian jet in Daret Azzeh, 20 miles west of Aleppo, on Wednesday.

DUBAI, United Arab Emirates — Syrian state media said on Wednesday that 34 people and possibly many more had died in twin car bombings in a suburb populated by minorities only a few miles from the center of Damascus, the capital, as the civil war swirls from north to south claiming ever higher casualties. One estimate by the government’s opponents put the death toll at 47.

There were also reports from witnesses in Turkey and antigovernment activists in Syria that for the second successive day insurgents had shot down a government aircraft in the north of the country, offering further evidence that the rebels are seeking a major shift by challenging the government’s dominance of the skies. It was not immediately clear how the aircraft, apparently a plane, had been brought down.

Video posted on the Internet by rebels showed wreckage with fires still burning around it. The aircraft appeared to show a tail assembly clearly visible jutting out of the debris. Such videos are difficult to verify, particularly in light of the restrictions facing reporters in Syria. However, the episode on Wednesday seemed to be confirmed by other witnesses.

“We watched a Syrian plane being shot down as it was flying low to drop bombs,” said Ugur Cuneydioglu, who said he observed the incident from a Turkish border village in southern Hatay Province. “It slowly went down in flames before it hit the ground. It was quite a scene,” Mr. Cuneydioglu said.

Video posted by insurgents on the Internet showed a man in aviator coveralls being carried away. It was not clear if the man was alive but the video said he had been treated in a makeshift hospital. A voice off-camera says, “This is the pilot who was shelling residents’ houses.”

The aircraft was said to have been brought down while it was attacking the town of Daret Azzeh, 20 miles west of Aleppo and close to the Turkish border. The town was the scene of a mass killing last June, when the government and the rebels blamed each other for the deaths and mutilation of 25 people. The video posted online said the plane had been brought down by “the free men of Daret Azzeh soldiers of God brigade.”

On Tuesday, Syrian rebels said they shot down a military helicopter with a surface-to-air missile outside Aleppo and they uploaded video that appeared to confirm that rebels have put their growing stock of heat-seeking missiles to effective use.

In recent months, rebels have used mainly machine guns to shoot down several Syrian Air Force helicopters and fixed-wing attack jets. In Tuesday’s case, the thick smoke trailing the projectile, combined with the elevation of the aircraft, strongly suggested that the helicopter was hit by a missile.

Rebels hailed the event as the culmination of their long pursuit of effective antiaircraft weapons, though it was not clear if the downing on Tuesday was an isolated tactical success or heralded a new phase in the war that would present a meaningful challenge to the Syrian government’s air supremacy. In Damascus, the official SANA news agency said the explosions in Jaramana outside the city at around 7 a.m. were the work of “terrorists,” the word used by the authorities to denote rebel forces seeking the overthrow of President Bashar al-Assad. Photographs on the SANA Web site showed wreckage and flames in what looked like a narrow alleyway with cars covered in chunks of debris from damaged buildings. The agency said the bombings were in the main square of Jaramana, which news reports said is largely populated by members of the Christian and Druse minorities. Residents said the neighborhood was home to many families who have fled other parts of Syria because of the conflict and to some Palestinian families. The blasts caused “huge material damage to the residential buildings and shops,” SANA said.

The photographs on the Web site showed shattered windows at the Abou Samra coffee house and gurneys laden with injured people clogging what seemed to be a hospital corridor.

SANA said two bombings in other neighborhoods caused minor damage. Activists reported that there were four explosions and said they were all “huge.”

Footage broadcast on Syria’s private Addounia channel and state television showed damage scarring gray six-story apartment houses above tangles of wrecked cars as ambulances arrived to transport the wounded and rescuers spraying rubble with fire hoses. The camera panned over bloodstained sidewalks.

The blasts seemed initially at least to shift the focus of the fighting from the north, where insurgents have claimed string of tactical breakthroughs in recent days, to areas ringing Damascus.

In the north in recent days, the insurgents also claimed to have seized air bases and a hydroelectric dam, apparently seeking both to expand their communications lines and to counter the government’s supremacy in the air.

The death toll from Wednesday’s bombings was not immediately confirmed. An activist group, the British-based Syrian Observatory for Human Rights, initially said that 29 people had died but revised the figure later to 47, of whom 38 had been identified. Of the 120 injured, the rebel group said, 23 people were in serious condition, meaning that the tally could climb higher.

The explosions reflected the dramatic shift since Syria’s uprising began in March 2011 as a peaceful protest centered on the southern town of Dara’a. It has since spread across the land in a full-blown civil war pitting government forces against a rebel army of Army defectors, disaffected civilians and what the authorities say are foreign jihadists.

German lawmakers condemn Google campaign against copyright law

BERLIN (Reuters) – Senior German politicians have denounced as propaganda a campaign by Google to mobilize public opinion against proposed legislation to let publishers charge search engines for displaying newspaper articles.

Internet lobbyists say they are worried the German law will set a precedent for other countries such as France and Italy that have shown an interest in having Google pay publishers for the right to show their news snippets in its search results.

Lawmakers in Berlin will debate the bill in the Bundestag (lower house) on Thursday. Google says the law would make it harder for users to retrieve information via the Internet.

Google launched its campaign against the bill on Tuesday with advertisements in German newspapers and a web information site called “Defend your web”.

“Such a law would hit every Internet user in Germany,” Stefan Tweraser, country manager for Google Germany, said in a statement. “An ancillary copyright means less information for consumers and higher costs for companies.”

The campaign has caused outrage among some members of German Chancellor Angela Merkel’s center-right coalition.

“The campaign initiated by Google is cheap propaganda,” said conservative lawmakers Guenter Krings and Ansgar Heveling.

“Under the guise of a supposed project for the freedom of the Internet, an attempt is being made to coopt its users for its own lobbying,” the two said in a statement.

Supporters of the law argue that newspaper publishers should be able to benefit from advertising revenues earned by search engines using their content.

Under the plans, publishers would get a bigger say over how their articles are used on the Internet and could charge search engines for showing articles or extracts.

German Justice Minister Sabine Leutheusser-Schnarrenberger, a member of the Free Democrats (FDP) who share power in Merkel’s government, said she was astonished that Google was trying to monopolize opinion-making. She is responsible for the law.

“PANIC MONGERING”

Germany’s newspaper industry, suffering from economic slowdown and keen to get its hands on any revenues it can, backs the plans and railed against Google’s campaign.

“The panic mongering from Google has no justification,” Germany’s BDZV newspaper association said in a statement.

“The argument from search engine companies that Internet searching and retrieval will be made more difficult is not serious. Private use, reading, following links and quoting will be possible, just as before.”

Internet lobbyists in Brussels fear the European Commission is sympathetic to publisher demands for a piece of Google’s profits online. Recent statements, they say, are proof.

“Consumers are not the only ones facing difficulties,” Michel Barnier, the EU’s internal market commissioner, said in a speech on November 7. “Think of newspaper publishers who see the content they produce being used by others to attract consumers on the net and generate advertising revenues.”

French newspapers and magazines want Google to pay them for linking to their articles on Google. The French government has named a mediator to negotiate with the press and Google to try to get a deal by the end of the year.

If no deal emerges, President Francois Hollande’s government will ask parliament to draft a law modifying copyright laws to protect the press from appropriation of its content online, according to a letter signed by two ministers on November 28.

Bonds, Clemens, Sosa on Hall ballot for first time

NEW YORK (AP) — Barry Bonds, Roger Clemens and Sammy Sosa are listed on the baseball Hall of Fame ballot for the first time, setting up an election sure to become a referendum on the Steroids Era.

The 37-player ballot was announced Wednesday.

More than 600 longtime members of the Baseball Writers' Association of America will vote through next month. Candidates need 75 percent for induction, and the results will be announced Jan. 9.

Bonds is the all-time home run champion with 762 and won a record seven MVP awards. Clemens set a record with seven Cy Young trophies and Sosa hit 609 homers. The voters will now decide whether drug allegations that tainted their huge numbers should keep them out of Cooperstown.

Craig Biggio, Mike Piazza and Curt Schilling are among the 24 first-time eligibles. Jack Morris, Jeff Bagwell and Tim Raines are the top holdover candidates.

The upcoming election is certain to fuel the most polarizing Hall discussion since career hits leader Pete Rose's betting troubles put him on baseball's permanently ineligible list, barring him from the BBWAA ballot.

While many continued to debate whether Rose should be enshrined, it was moot because there is currently no way he can be considered.

On deck, though, are some of the game's biggest names — along with a lot of the sport's biggest baggage.

Bonds, Clemens and Sosa each posted monster statistics, though their accomplishments were shadowed by accusations they used performance-enhancing drugs. And as baseball keeps trying to rid itself of PEDs, their impact on HRs, RBIs and Ws remains a prickly problem.

Bonds was baseball's premier slugger on his generation and Clemens ranks ninth in career wins with 354. Sosa is eighth on the home run chart with 609.

Fans, players and Hall of Fame members have all chimed in about whether stars who supposedly juiced up should make it to Cooperstown.

Many of those opposed say drug cheats should never be afforded baseball's highest individual honors. Others on the opposite side claim the use of PEDs was pervasive in the 1980s, 1990s and early 2000s, and shouldn't disqualify candidates.

If recent voting for the Hall is any indication, the odds are solidly stacked against Bonds, Clemens and Sosa.

Mark McGwire is 10th on the career home run list with 583, but has never received even 24 percent in his six tries. Big Mac has admitted to using steroids and human growth hormone.

Rafael Palmeiro is among only four players with 500 homers and 3,000 hits, yet has gotten a high of 12.6 percent in his two years on the ballot. Palmeiro drew a 10-day suspension in 2005 after a positive test for performance-enhancing drugs, and said the result was due to a vitamin vial given to him by teammate Miguel Tejada.

Biggio topped the 3,000-hit mark — which always has been considered an automatic credential for Cooperstown — and spent his entire career with the Houston Astros.

Schilling was 216-146 and won three World Series championships, including his "bloody sock" performance for the Boston Red Sox in 2004.

F.D.A. May Tap Experts on Energy Drinks

The Food and Drug Administration said in a letter released on Tuesday that it was likely to seek advice from outside experts to help determine whether energy drinks posed particular risks to teenagers or people with underlying health problems.

The letter appears to signal a change in the agency’s approach to the drinks, which contain high levels of caffeine.

Previously, F.D.A. officials have said that they were investigating possible risks posed by popular products like 5-Hour Energy, Monster Energy and Red Bull. But an agency spokeswoman, Shelly Burgess, said the new letter was the first time that the F.D.A. had said it might turn to outside experts.

The F.D.A. letter, which was released Tuesday by Senator Richard J. Durbin of Illinois and Senator Richard Blumenthal of Connecticut, follows disclosures that the agency received reports of 18 deaths and over 150 injuries that mentioned the possible involvement of energy drinks.

The filing of such reports with the F.D.A. does not prove that a product was responsible for a death or an injury. Energy drink makers have said their products are safe and were not responsible for the health problems.

The officials said a review of the drinks might be “greatly enhanced by also engaging specialized expertise” from an outside group, like the Institute of Medicine, which is part of the National Academy of Sciences.

Industry analysts said the letter indicated that the F.D.A. did not plan any immediate actions on energy drinks, an interpretation that set off a rally on Tuesday in the stock of Monster Beverage, the producer of Monster Energy. Company shares closed at $51.97, up over 13 percent. Any regulatory outcome is likely to be “benign,” Judy Hong, an analyst at Goldman Sachs, said in a note to investors, according to Bloomberg News.

In Canada, however, the use of an outside panel led to limits on caffeine levels in energy drinks.

In their letter, F.D.A. officials indicated that an outside review would focus on the possible risks posed by high levels of caffeine, a stimulant, to certain groups. They reiterated that daily consumption of significant levels of caffeine, which is found in products like coffee and tea, is safe.

“Areas of particular focus would include such matters as the vulnerability of certain populations to stimulants and the incidence and consequence of excessive consumption” of energy drinks, especially by young people, F.D.A. officials wrote.

In Canada, an expert panel made several recommendations, including arguing that such beverages be labeled “stimulant drug-containing drinks.”

Health Canada, that country’s counterpart to the F.D.A., did not adopt many of the group’s recommendations, but it has put in place new rules limiting caffeine levels in cans of energy drinks to 180 milligrams.

Some larger-size cans of energy drinks sold in the United States, like the 24-ounce can of Monster Energy and the 20-ounce can of Red Bull, have caffeine levels above that limit.

An eight-ounce cup of coffee, depending on how it is made, can contain from 100 to 150 milligrams of caffeine.

In the new letter, F.D.A. officials also said that studies that had examined other ingredients, like taurine, that are often used in energy drinks had determined those substances were safe. The agency also said that a survey suggested that energy drinks constitute a small portion of the caffeine consumed in this country, even by teenagers.

Ex-NASA Scientist’s Data Fears Come True

In 2007, Robert M. Nelson, an astronomer, and 27 other scientists at the Jet Propulsion Laboratory sued NASA arguing that the space agency’s background checks of employees of government contractors were unnecessarily invasive and violated their privacy rights.

Privacy advocates chimed in as well, contending that the space agency would not be able to protect the confidential details it was collecting.

The scientists took their case all the way to the Supreme Court only to lose last year.

This month, Dr. Nelson opened a letter from NASA telling him of a significant data breach that could potentially expose him to identity theft.

The very thing he and advocates worried about had occurred. A laptop used by an employee at NASA’s headquarters in Washington had been stolen from a car parked on the street on Halloween, the space agency said.

Although the laptop itself was password protected, unencrypted files on the laptop contained personal information on about 10,000 NASA employees — including details like their names, birth dates, Social Security numbers and in some cases, details related to background checks into employees’ personal lives.

Millions of Americans have received similar data breach notices from employers, government agencies, medical centers, banks and retailers. NASA in particular has been subject to “numerous cyberattacks” and computer thefts in recent years, according to a report from the Government Accountability Office, an agency that conducts research for Congress.

Even so, Dr. Nelson, who recently retired from the Jet Propulsion Laboratory, a research facility operated by the California Institute of Technology under a contract with NASA, stands out as a glaring example of security lapses involving personal data, privacy advocates say.

“To the extent that Robert Nelson looks like millions of other people working for firms employed by the federal government, this would seem to be a real problem,” said Marc Rotenberg, the executive director of the Electronic Privacy Information Center, an advocacy group which filed a friend-of-the-court brief for Dr. Nelson in the Supreme Court case.

In a 2009 report titled “NASA Needs to Remedy Vulnerabilities in Key Networks,” the Government Accountability Office noted that the agency had reported 1,120 security incidents in fiscal 2007 and 2008 alone.

It also singled out an incident in 2009 in which a NASA center reported the theft of a laptop containing about 3,000 unencrypted files about arms traffic regulations and wind tunnel tests for a supersonic jet.

“NASA had not installed full-disk encryption on its laptops at all three centers,” the report said. “As a result, sensitive data transmitted through the unclassified network or stored on laptop computers were at an increased risk of being compromised.” Other federal agencies have had similar problems. In 2006, for example, the Department of Veteran’s Affairs reported the theft of an employee laptop and hard drive that contained personal details on about 26.5 million veterans. Last year, the G.A.O. cited the Internal Revenue Service for weaknesses in data control that could “jeopardize the confidentiality, integrity, and availability of financial and sensitive taxpayer information.”

Also last year, the Securities and Exchange Commission warned its employees that their confidential financial information, like brokerage transactions, might have been compromised because an agency contractor had granted data access to a subcontractor without the S.E.C.’s authorization.

In a phone interview, Dr. Nelson, the astronomer, said he planned to hold a news conference on Wednesday morning in which he would ask members of Congress to investigate NASA’s data collection practices and the recent data breach.

Robert Jacobs, a NASA spokesman, said the agency’s data security policy already adequately protected employees and contractors because it required computers to be encrypted before employees took them off agency premises. “We are talking about a computer that should not have left the building in the first place,” Mr. Jacobs said. “The data would have been secure had the employee followed policy.”

The government argued in the case Dr. Nelson filed that a law called the Privacy Act, which governs data collection by federal agencies, provided the scientists with sufficient protection. The case reached the Supreme Court, which upheld government background checks for employees of contractors. The roots of Dr. Nelson’s case against NASA date back to 2004 when the Department of Homeland Security, under a directive signed by President George Bush, required federal agencies to adopt uniform identification credentials for all civil servants and contract employees. As part of the ID card standardization process, the department recommended agencies institute background checks.

Several years later, when NASA announced it intended to start doing background checks at the Jet Propulsion Laboratory, Dr. Nelson and other scientists there objected.

Those security checks could have included inquiries into medical treatment, counseling for drug use, or any “adverse” information about employees such as sexual activity, or participation in protests, said Dan Stormer, a lawyer representing Dr. Nelson.

But Dr. Nelson and other long-term employees of the lab challenged the legality of those checks, arguing that they violated their privacy rights. NASA, they said, had not established a legitimate need for such extensive investigations about low-risk employees like themselves who did not have security clearances or handle confidential information. Dr. Nelson, for example, specializes in solar system science — concerning, for example, Jupiter’s moon Io and Titan, a moon of Saturn — and publishes his work in scientific journals

“It was an invitation to an open-ended fishing expedition,” Dr. Nelson said of the background checks.

In friend of the court briefs for Dr. Nelson, privacy groups cited many data security problems at federal agencies, arguing that there was a risk that NASA was not equipped to protect the confidential details it was collecting about employees and contractors.

In 2008, the United States Court of Appeals for the Ninth Circuit in San Francisco temporarily halted the background checks, saying that the case had raised important questions about privacy rights. But last year, the Supreme Court upheld the background investigations of employees of government contractors.

Dr. Nelson said he retired from the Jet Propulsion Laboratory last June rather than submit to a background check. He now works as a senior scientist at the Planetary Science Institute of Tucson.

NASA has contracted with ID Experts, a data breach company, to help protect employees whose data was contained on the stolen laptop against identity theft. Mr. Jacobs, the NASA spokesman, said the agency has encrypted almost 80 percent of its laptops and plans to encrypt the rest by Dec. 21. He added that he too received a letter from NASA warning that his personal information might have been compromised by the laptop theft.

Protesters Gather Again in Cairo Streets to Denounce Morsi

CAIRO — Thousands of people flowed into the streets of Cairo, the Egyptian capital, Tuesday afternoon for a day of protest against President Mohamed Morsi’s attempt to assert broad new powers for the duration of the country’s political transition, dismissing his efforts just the night before to reaffirm his deference to Egyptian law and courts.

By early Tuesday afternoon in Cairo, a dense crowd of hundreds had gathered outside the headquarters of a trade group for lawyers, and thousands more had filed in around a small tent city in Tahrir Square. In an echo of the chants against Hosni Mubarak, Egyptian’s ousted president, almost two years ago, they shouted, “Leave, leave!” and “Bring down the regime!” They also denounced the spiritual leader of the Muslim Brotherhood, the Islamist group allied with Mr. Morsi.

A few blocks away, in a square near the American Embassy and the Interior Ministry headquarters, groups of young men resumed a running battle that began nine days ago, throwing rocks and tear gas canisters at riot police officers. Although those clashes grew out of anger over the deaths of dozens of protesters in similar clashes one year ago, many of the combatants have happily adopted the banner of protest against Mr. Morsi as well.

Egyptian television had captured the growing polarization of the country on Monday in split-screen coverage of two simultaneous funerals, each for a teenage boy killed in clashes set off by disputes over the new president’s powers. Thousands of supporters of Mr. Morsi and his allies in the Muslim Brotherhood marched through the streets of the Nile Delta city of Damanhour to bury a 15-year-old killed outside a Brotherhood office during an attack by protesters. And in Tahrir Square here in Cairo, thousands gathered to bury a 16-year-old killed in clashes with riot police officers and to chant slogans blaming Mr. Morsi for his death. “Morsi killed him,” the boy’s father said in a video statement circulated over the Internet.

“Now blood has been spilled by political factions, so this is not going to go away,” said Rabab el-Mahdi, a professor at the American University in Cairo and a left-leaning activist, adding that these were the first deaths rival factions had blamed on each other and not on the security forces of the Mubarak government since the uprising began last year. Still larger crowds were expected in the evening, as marchers from around the city headed for the square. Many schools and other businesses had closed in anticipation of bedlam, and on Monday, the Brotherhood called off a rival demonstration in support of the president, saying it wanted to avoid violence.

Egypt’s Supreme Judicial Council met again on Tuesday to consider its response to the president, and the leader of Al Azhar, a center of Sunni Muslim learning that is regarded as the pre-eminent moral authority here, met with groups of political leaders in an effort to resolve the battle over the president’s decree and the deadlock in the constitutional assembly, which is trying to draw up a new constitution.

But even as Mr. Morsi met with top judges Monday night in an effort to resolve the crisis, a coalition of opposition leaders held a news conference to declare that preserving the role of the courts was only the first step in a broader campaign against what Abdel Haleem Qandeil, a liberal intellectual, called “the miserable failure of the rule of the Muslim Brothers.” Mr. Morsi “unilaterally broke the contract with the people,” he declared. “We have to be ready to stand up to this group, protest to protest, square to square, and to confront the bullying.”

Mr. Morsi’s effort to remove the last check on his power over the political transition had brought the country’s fractious opposition groups together for the first time in a united front against the Brotherhood. But the show of unity papered over deep divisions between groups and even within them, said Ms. Mahdi of the American University.

“This is not a united front, and I am inside it,” she said. “Every single political group in the country is now divided over this — is this decree revolutionary justice or building a new dictatorship? Should we align ourselves with folool” — the colloquial term for the remnants of the old political elite — “or should we be revolutionary purists? Is it a conflict between the Muslim Brotherhood and the pro-Mubarak judiciary, or is this the beginning of a fascist regime in the making?”

Nintendo says more than 400,000 Wii Us sold in US

NEW YORK (AP) — Nintendo has sold more than 400,000 of its new video game console, the Wii U, in its first week on sale in the U.S., the company said Monday.

The Wii U launched on Nov. 18 in the U.S. at a starting price of $ 300. Nintendo said the sales figure, based on internal estimates, is through Saturday, or seven days later.

The Wii U is the first major game console to launch in six years. It comes with a new touch-screen controller that promises to change how people play games by offering different people in the same room a different experience, depending on the controller used.

Six years ago, Nintendo Co. sold 475,000 of the original Wii in that console’s first seven days in stores, according to data from the NPD Group. The original Wii remains available, and Nintendo said it sold more than 300,000 of them last week, along with roughly 250,000 handheld Nintendo 3DS units and about 275,000 of the Nintendo DS.

At this early stage, demand isn’t the only factor dictating how many consoles are sold. Supply is, too. This means it’s likely that more people wanted to buy the Wii U in the first week than those who were able to. The original Wii was in short supply more than a year after it went on sale.

As of Monday afternoon, the website of Best Buy Co. was sold out of the Wii U. Video game retailer GameStop Corp. said there was at least a three day wait for a deluxe Wii U, which costs $ 350, has more memory and comes with a game called “Nintendo Land.” GameStop still had the basic, $ 300 version available.

Wedbush analyst Michael Pachter estimates that Nintendo will ship 1 million to 1.5 million Wii Us in the U.S. through the end of January.

Eagles lose receiver DeSean Jackson to injury

PHILADELPHIA (AP) — The Philadelphia Eagles will place wide receiver DeSean Jackson on injured reserve after he sustained multiple rib fractures in Monday night's loss to Carolina.

Jackson leads the team with 45 catches and 700 yards receiving, but has only two touchdowns. Coach Andy Reid says the injury could take six weeks to heal.

Reid says running back LeSean McCoy remains in phase one of his concussion recovery and Michael Vick is in the fourth of five stages. Vick has missed the last two games and McCoy didn't play against the Panthers.

Defensive tackle Fletcher Cox injured his tailbone and offensive lineman King Dunlap sprained his knee. Neither will practice Wednesday.

The Eagles (3-8) have lost seven straight games. They'll visit Dallas (5-6) next Sunday night.

Imaging Shows Progressive Damage by Parkinson’s

For the first time, researchers at the Massachusetts Institute of Technology report, brain imaging has been able to show in living patients the progressive damage Parkinson’s disease causes to two small structures deep in the brain.

The new technique confirms some ideas about the overall progress of the disease in the brain. But the effects of Parkinson’s vary in patients, the researchers said, and in the future, the refinement in imaging may help doctors monitor how the disease is affecting different people and adjust treatment accordingly.

The outward symptoms and progress of Parkinson’s disease — tremors, stiffness, weakness — have been well known since James Parkinson first described them in 1817. But its progress in the brain has been harder to document.

Some of the structures affected by the disease have been buried too deep to see clearly even with advances in brain imaging. An important recent hypothesis about how the disease progresses was based on the examinations of brains of patients who had died.

Now, a group of scientists at M.I.T. and Massachusetts General Hospital report that they have worked out a way to combine four different sorts of M.R.I. to get clear pictures of damage to two brain structures in people living with Parkinson’s. In doing so, they have added support to one part of the recent hypothesis, which is that the disease first strikes an area involved in movement and later progresses to a higher part of the brain more involved in memory and attention.

Suzanne Corkin, a professor emerita of behavioral neuroscience at M.I.T. and the senior author on the paper published online Monday in The Archives of Neurology, said that this progression was part of the hypothesis put forward in 2003 by Heiko Braak, a German neuroscientist, based on autopsies.

But, she said, because of the limits of brain imaging, “nobody could test this in living patients.”

David A. Ziegler, who was at M.I.T. when the research was done, and is now a postdoctoral researcher at the University of California, San Francisco, said that the study, of 29 patients with Parkinson’s and 27 healthy patients of roughly the same age, showed that the peanut-sized substantia nigra lost volume first, and another structure called the basal forebrain, involved in memory and attention, was struck later.

Glenda Halliday, a neuroscientist at Neuroscience Research Australia and the University of New South Wales, who was not involved in the study, said the paper confirmed “the progression of degeneration in two important affected brain regions in people with Parkinson’s.”

Dr. Corkin, Dr. Ziegler and their colleagues developed a way to use four different varieties of M.R.I. — each using different settings on the same machine — to come up with four different images that could be used to form one image that showed structures deep in the brain like the substantia nigra, long known to be important in Parkinson’s.

The disease kills brain cells, shrinking the parts of the brain that it affects, and the comparative study showed that the reduction in size of the substantia nigra showed up in early stage Parkinson’s patients, compared with a healthy group.

The reduction in size in the basal forebrain, compared with the healthy group, did not show up in the patients in the early stage, but was clear in patients in the later stage.

“This is a project we’ve been working on in our lab for years,” she said. A next step, already in progress, is to correlate damage to specific brain structures with symptoms.

Parkinson’s, she said, is a disease that shows the same broad outlines of development in most patients, but with considerable variation. Dementia may arrive early or may not appear. The M.R.I. technique described in the paper, she said, might help tease out what is going on in the brain in subgroups of Parkinson’s patients that show different symptoms and could influence treatment.

One important difference between the two brain structures is that damage to the substantia nigra decreases production of the neurotransmitter dopamine, while a smaller basal forebrain would reduce the production of a different chemical, acetylcholine.

The research is just one step, Dr. Ziegler said. One of the “big outstanding questions,” he said, is whether all patients will eventually get dementia.

News Analysis: St. Jude Medical Suffers for Redacting a Product Name

Peter Muhly for The New York Times

Dr. Ernest Lau holds a Durata lead from a St. Jude Medical Fortify ICD, an implanted heart defibrillator.

IS covering a product’s name in a public document a sign that a company has something to hide? And how should doctors, patients and investors react if the product at issue is one on which peoples’ lives and a company’s fortunes depend?

Such questions now loom over St. Jude Medical after the disclosure last week that its executives had blacked out the name of a heart device component when they released a critical federal report involving the product. The value of St. Jude has since plummeted more than $1 billion, or 12 percent. But the company’s actions may have a more lasting impact on its reputation and the health of patients, some experts say.

Last week’s incident was the latest development in a controversy involving the component, an electrical wire that connects an implanted defibrillator to a patient’s heart. St. Jude officials say the wire, which is known as the Durata, is safe. But uncertainty about the company’s statements is growing, underscored by its handling of the report, which involved a Food and Drug Administration inspection of a plant that makes the Durata.

St. Jude released that report in October as part of a filing with the Securities and Exchange Commission. The F.D.A. provides device makers with the reports in an unaltered form, and they may contain criticisms of a company’s procedures.

But the version of the report that St. Jude filed with the S.E.C. left some doctors and analysts uncertain about which company product or products were at issue for a simple reason — St. Jude had redacted, or blocked out, all 20 references to the Durata in it.

Company executives said they had done so based on their “good faith” interpretation of how the F.D.A. would act if it publicly released the report under the Freedom of Information Act. But both an F.D.A spokeswoman and a lawyer who specializes in medical devices took exception with that view, saying that names of approved products typically do not qualify as the type of confidential business information that the F.D.A. would redact.

Among other things, F.D.A. inspectors found significant flaws in the company’s testing and oversight of the Durata. It was those revelations and the implications that the problems could lead to further F.D.A. action against St. Jude that led to the sharp fall last week in its stock price.

In 2005, Guidant, a device maker that no longer exists, also found itself under scrutiny. Back then, its executives decided not to tell doctors that one of its defibrillators could short-circuit when a patient needed an electrical jolt to save a life. The expert who brought the Guidant problem to light, Dr. Robert Hauser, a heart specialist in Minnesota, has also raised concerns about the St. Jude wires, adding that he believes that its executives have been less than forthright.

“Patients and physicians would appreciate more information,” Dr. Hauser said.

In an earlier interview, St. Jude’s chief executive, Daniel J. Starks, said the company had hidden nothing about the Durata or another heart wire named the Riata, which it stopped selling in 2010.

“We’ve been more transparent than others,” said Mr. Starks, referring to company competitors like Medtronic.

Still, some Wall Street analysts share Dr. Hauser’s view. And if one St. Jude executive can claim credit for shaping their opinion, it would be Mr. Starks.

Earlier this year, he sought, among other things, to have a medical journal retract an article written by Dr. Hauser that was critical of the Riata. The publication refused.

Now, after St. Jude’s latest misfire, Wall Street analysts, who usually agree more than disagree, are placing wildly differing bets on St. Jude, with some valuing it at $48 a share and others at $30. On Monday, St. Jude closed at $31.86 on the New York Stock Exchange.

One of those bearish analysts, Matthew Dodds of Citigroup, said he thought the Food and Drug Administration might act soon on Durata. “I believe that a lot of their actions have made the situation worse, ” he said of the company’s executives.

A St. Jude spokeswoman, Amy Jo Meyer, reiterated the company’s stance that it had interpreted agency rules in “good faith” when releasing the redacted report about the Durata. An F.D.A. spokeswoman, Mary Long, said the agency did not consider the names of approved products to be confidential. And a lawyer, William Vodra, said that while device makers try to make a confidentiality argument for product data they consider embarrassing, like injury reports, they rarely succeed.

“In my experience, the F.D.A. consistently rejects” such arguments, Mr. Vodra wrote in an e-mail.

For patients, the dilemma may become more excruciating. The company’s earlier heart wire, the Riata, has begun failing prematurely in some of the 128,000 patients worldwide who received it. And those patients and their doctors face a difficult decision: whether to leave it in place or have it surgically removed, a procedure that carries significant risks.

St. Jude executives say that the Durata, which uses a different type of insulation than the Riata, is not prone to such problems.

And with the Durata already implanted in 278,000 people, many heart specialists certainly hope they are right.
