    Dentistry Today: Quantum Detection of Tooth Decay

    Quantum Detection of Tooth Decay

    A new laser device designed to detect the earliest stages of tooth decay could help dentists stop cavities in their tracks.

    A newly developed laser device that uses thermal radiation and light waves to detect tiny, subsurface lesions in teeth could potentially unseat x-rays as the diagnostic standard in dental care.Researchers at the University of Toronto’s Centre for Advanced Diffusion Wave Studies say that the technology can spot lesions as small as 50 microns in between teeth, one of the most difficult spaces to spot cavities, and up to 5 millimeters below the surface of a tooth. This is well outside the boundaries of x-ray detection without exposing the patient to radiation. The researchers built a clinical prototype of the device this month and plan to begin clinical tests next year.

    Detecting the earliest signs of decay could bring big changes to dentistry. “You need to lose about 30 percent of the mineral before you begin to see it on an x-ray; that’s why these new technologies are so exciting,” says Christopher Fox, executive director of the International Association for Dental Research, based in Alexandria, Virginia, and a 20-year industry veteran. “If we can detect early mineral loss, we have different intervention technologies we can use to prevent getting to that drill and fill point.”

    Fox calls Quantum’s approach “very interesting” but says that x-rays will always be needed to assess periodontal health, such as the deterioration of bone structure around the teeth.

    Testing teeth: Researchers at the University of Toronto have just assembled a clinical prototype of a new laser device (shown above) that measures thermal and light frequencies to detect early signs of decay below a tooth’s surface, where demineralization is difficult to spot with x-ray technology. The optical pen beams heat-emitting infrared light onto a tooth’s surface, and sensors within the pen measure heat and light waves that bounce back. Certain wave patterns can reveal loss of mineral content in a tooth, a sign of early decay that can lead to troublesome cavities. Credit: Quantum Technologies

    Don’t discard the x-rays yet, Doc. But, this technology looks promising for another significant diagnostic tool for the dentist – one that can detect early caries, earlier than ever before.

    Giuliani Notes: Oakland California Welcomes Rudy

    giulianimarch23aaweb

    Former New York City mayor and presidential contender Rudy Giuliani kisses a baby while visiting supporters and customers at the Fat Lady Restaurant in Oakland, Calif., Friday, March 23, 2007. Giuliani also gave a brief news conference.

    Giuliani woos Oakland GOP in quick visit

    Frontrunning 2008 Republican presidential candidate Rudy Giuliani pressed the flesh, took questions and — yes — even kissed a baby at a restaurant here Friday, underscoring how even Democratic strongholds won’t be ignored by the GOP in this primary race.

    The former New York City mayor arrived promptly at 3 p.m. at the Fat Lady near Jack London Square, a restaurant and bar popular with downtown business people and attorneys — the sort of fiscally conservative, socially liberal Republicans who make the Bay Area such a happy hunting ground for the pro-choice, pro-gay-rights Giuliani.

    “I’ll buy you a beer, Rudy,” a patron called as Giuliani made his way through scores of people who’d packed the small restaurant; at the rear, he ducked into the men’s room to don a red, white and blue tie. “I’m so glad you’re running~,” another patron told him as he emerged.

    Outside, Giuliani told reporters the House’s vote Friday to tie almost $100 billion in Iraq war and other spending to a timetable for a 2008 pullout is “a big mistake. … You don’t let your enemies know what you’re going to do.”

    On Joint Chiefs of Staff Chairman Gen. Peter Pace’s recent statement that homosexuality is “immoral,” Giuliani said, “Morality is judged between you and God,” and as a Catholic he hews to Jesus’ wisdom in decreeing, “Let he who is without sin, cast the first stone.”

    On immigration, he said security is key — “We’ve got to know everybody who’s in the United States” — and called for a system in which all immigrants are registered, photographed and issued tamperproof identification.

    giulianimarch23eeweb

    But, why is Rudy campaigning in Alameda County where only 17 per cent are registered Republicans? The California GOP selection rules that apportion nominating delegates by Congressional District and…….

    Rudy is planning ahead to the general election when he hopes to be the first GOP Presidential candidate since 1988 to carry California.

    Only about 17 percent of Alameda County’s registered voters are Republicans, and only about 7 percent of Oakland’s. But California’s Republican presidential primary is no longer a statewide winner-take all; instead, the GOP presidential candidate with the most votes in each congressional district will get that district’s delegates.

    Hence Giuliani’s interest in pitching woo somewhere like Oakland: In a way, he gets more bang for his buck here. Carrying a majority of the 31,000 Republicans in Democrat Barbara Lee’s 9th Congressional District would win him three delegates, the same as winning some other, more GOP-heavy district.

    Hizzoner continues his California campaign swing:

    He had a fundraiser Friday night in San Francisco and has fundraisers scheduled for Saturday morning in Monterey, Saturday afternoon in Newport Beach and Sunday near Santa Barbara.

    Giuliani Notes: Hotline – Rudy Number One

    giulianimarch23rweb

    2008 Race Rankings: Giuliani’s In The Lead

    The Hotline’s Marc Ambinder and NBC News Political Director Chuck Todd will collaborate on race rankings until we don’t.

    We’ve got a new No. 1 this week, and it reflects several realities. For one thing, there’s a deep hunger on the Republican side for a candidate who can rebrand the party after seven-plus years of President Bush. Also, the issue stuff just doesn’t seem to be hurting Rudy Giuliani yet, and we can’t help but think that the early predictions of his doom were overstated.

    These rankings are ordered by likelihood of winning the Republican primary and are based on a number of factors, including organization, money, buzz and polling. Click here for Democratic rankings.

    1. Rudy Giuliani Last Ranking: 2

    There are three distinct camps among those Republicans who don’t think Giuliani will win the nomination: the McCain camp, the Huckabee camp and the Arlington camp. The McCain camp believes questions about Giuliani’s business practices and his personal character will disqualify him, and that his liberal positions on issues will be the coup de grace. The MSM is mostly in this camp. The Huckabee camp believes Giuliani is objectively too liberal to be the nominee and will not vote for him. The Arlington camp doesn’t know whether Giuliani will be elected but worries — for the sake of its organizations’ bottom lines — how a social liberal would affect the power and influence of organized conservative interests. If the election were held tomorrow, Giuliani would win. He doesn’t have McCain’s organizational strength, money, or endorsements, but he has a solid and growing lead in national polls. And so far, he’s repelled some fairly devastating attacks (like the notion that he does not speak to his son).
    Fundraising projection: $15 million, +/- $3 million. Fundraising ranking: 3.

    *****

    Hotline is merely parroting the polls that show Rudy in firm control, particularly in states that vote on Super Duper Tuesday, February 5, 2008.

    Hizzoner does not have to win Iowa, New Hampshire or South Carolina to be a viable candidate on February 5th. But, today, he EVEN contends in these states.

    Watch the fundraising numbers this next week.

    If McCain’s numbers are NOT good, no matter what spin his campaign churns, the race may be over for him.

    Iran Watch: Are Seized British Troops Hostages?

    iranmarch232007hweb

    A graphic locating the waterway where Iran seized British navy sailors. The United States Friday called for the release of a group of British sailors held by Iran saying they had been carrying out “routine” inspections in Iraqi waters.

    Hostage fears over troops seized by Iran

    Britain’s crisis with Iran deepened last night after Tehran justified seizing 15 British servicemen by claiming that they had strayed into Iranian territorial waters “illegally”.

    The announcement appeared to rule out any hope that the incident was a simple mistake that could be quickly rectified.

    Instead, there were growing fears that the 15 British sailors and Royal Marines were victims of a deliberate ambush on the disputed Shatt al-Arab waterway by Iranian Revolutionary Guards, perhaps seeking to use the captives as hostages in the increasingly tense stand-off between the West and Iran over its nuclear programme.

    Iran blamed Britain for the border incident. “British chargé d’affaires Kate Smith was summoned to the Foreign Ministry to receive a firm protest from Iran against the illegal entry of British sailors into Iranian territorial waters,” said a statement from the Ministry of Foreign Affairs in Tehran.

    “This makes a number of times that British sailors have illegally entered Iranian territorial waters at Arvand Roud. They were arrested by border guards for investigation and questioning,” the statement added.

    Iran may be biting off more than it can chew.

    The United States and Israel are looking for any excuse to militarily neuter Iran’s nuclear program.

    This may be it.

    President Ahmadinejad canceled his appearance before the United Nations Security Council tomorrow. He claims it was because of the United States not issuing timely visas. This was denied by the United States State Department.

    So, is Iran holding these Brits as a bargaining chip over their nuclear program and United Nations sanctions?

    Iran is playing with fire – nuclear fire.

    Iran Nuclear Watch: Ahmadinejad Cancels United Nations Appearance

    iranmarch232007aaweb

    Iran’s President Mahmoud Ahmadinejad speaks upon his arrival at the Khartoum airport, in this February 28, 2007 file photo. Ahmadinejad has canceled his visit to New York to address the U.N. Security Council because of delays in granting visas to his entourage, Tehran’s U.N. ambassador said on March 23, 2007. Ahmadinejad had wanted to address the council before it votes on imposing new sanctions on Iran for its nuclear program. The meeting is expected to be held on Saturday, although it has not been officially scheduled yet.

    Iran’s President Cancels U.N. Appearance

    Iranian President Mahmoud Ahmadinejad has canceled his trip to New York to address the U.N. Security Council before a vote on whether to impose further sanctions against his country for refusing to stop enriching uranium, the Foreign Ministry spokesman said Friday.

    Mohammed Ali Hosseini, the spokesman, told Iranian state television that the trip was scrapped because of “America’s obstruction in issuing visas” to the Iranian delegation that was to travel to New York.

    A diplomat on the Security Council said Ahmadinejad would instead send his deputy foreign minister Saturday to address the Security Council before the vote. The diplomat spoke on condition of anonymity because there had not been an official announcement.

    Mohammad Mir Ali Mohammadi, press secretary of Iran’s mission at the U.N., told The Associated Press the U.S. did not deliver a visa to the U.S. Embassy in Bern, Switzerland, in time for the Iranian president to pick it up before for the council session Saturday.

    This is an EXCUSE.

    Is the REAL reason this?

    Perhaps.

    Anyone want to bet that the feckless United Nations Security Council cancels its meeting until Monday or Tuesday so that Mahmoud can attend?

    Stay tuned……..

    Giuliani Notes: Fred Thompson Eroding Rudy’s Support?

    giulianidecember1aweb

    New Iowa, New Hampshire Numbers

    Did all that access McCain gave to local press on the Straight Talk Express last week pay off?

    ARG has new poll numbers out today (methodology and trendlines in the links) from Iowa and New Hampshire that Dick Bennett, the group’s pollster, says reflect two things. First, including Fred Thompson in the mix, which Bennett did, takes support away from Rudy. Second, McCain’s hitting the trail in earnest last week in the two early states has helped him reclaim some Independents who had strayed.

    In Iowa, ARG now has McCain and Rudy tied at 29%, with Thompson at 12% and Romney at 10%. 11% of likely caucus goers — a notoriously tough universe to sample — said they were undecided. McCain leads Giuliani 39%-30% among Independents in the Hawkeye State.

    In New Hampshire, ARG has McCain at 23% to Rudy’s 19%. Romney gets 17%, Newt 11% and Thompson 10%. 15% of likely Granite State primary voters are undecided. Among Indepdenents there — the folks who powered the maverick to victory in the 2000 New Hampshire primary — McCain’s lead over Rudy grows to 33%-22%.

    Lets look at the numbers:

    giulianimarch23cweb

    giulianimarch23bweb2

    A Fred Thompson candidacy does not bode well for Mayor Giuliani in New Hampshire or Iowa.

    But, will Thompson run?

    Perhaps – especially since he is polling well without even campaigning.

    Design Review: Rudy Giuliani for President

    The oddest thing about this homepage is the layout. For some reason the page is falling out of the right hand side. All content is within the internal boundary of the site except the action items and the store, which appear to be forced outside by bad coding, but (as noted above) is actually intended. This is such an odd presentation that I have to think it was pushed out the door just a bit before it was ready. Low marks for the Rudy2008 design at this point.

    From: Brent Seaborn, Strategy Director
    Date: March 22, 2007
    RE: Mayor Giuliani’s Ballot Strength and Conservative Voter Support

    Growth in Mayor Giuliani’s Ballot Strength
    In early 2007, some people said that Mayor Giuliani would not run for President. On February 5th, Mayor Giuliani filed his FEC paperwork and legally declared himself a candidate for the Presidency. He ended this momentous day with an appearance on Hannity and Colmes.Since the Mayor made his intention to run for President clear, we have seen notable growth in support for our campaign. Before February, 5th, we were leading in major media polls by an average of 5-points. Since February, 5th our lead has grown to an average of nearly 20-points.

    Time -4 14 18
    Newsweek 4 25 21

    The Mayor is Better Known to Conservatives than Some will Acknowledge
    Many columnists and pundits question what will happen when Republicans “find out about the Mayor’s views on social issues.” Many of these stories are being generated by the same people that speculated that Mayor Giuliani would never run for President. Over the course of the last month, that question has been dispelled.A recent Newsweek poll shows Mayor Giuliani with a 25-point lead among Republican and Republican leaning voters and a 30-point lead among social conservatives. Mayor Giuliani has a wider lead among social conservatives than he does among Republicans in general. Social conservatives already know who Rudy Giuliani is. In fact, more than 70% say they know “some or a lot” about him – these numbers are almost identical or better than other candidates in the race.

    Social conservatives are already more likely than Republicans in general to know the Mayor’s positions on key issues. Social conservatives are tuned in to the campaign and they like what they see in Mayor Giuliani.

    According to recent analysis by Gallup Poll, Mayor Giuliani receives 47% of the votes among those that attend church “nearly weekly or monthly,” leading his nearest opponent by 28-points. Mayor Giuliani’s ballot share decreases to 31% among those that “attended church weekly” – yet he maintains a 7-point lead over his nearest opponent.

    After reviewing other data, I have found similar evidence.

    About half of Republican primary voters consider themselves to be “very conservative.” Among those “very conservative” Republican voters, Mayor Giuliani generally maintains a lead.

    Another interesting point, about two-thirds of “very conservative” Republican primary voters consider Mayor Giuliani to be a moderate or a liberal. Yet even with these voters, Mayor Giuliani holds a 5-point lead over his nearest competitor.

    The fact is – most Republicans believe that Mayor Giuliani is a social moderate or liberal and Mayor Giuliani leads all major candidates in this race (even among “very conservative” Republicans).

    There are, of course, some voters that will never vote for Mayor Giuliani, and we know that we will see polls tighten. But the “when voters find out about Rudy’s record the sky will fall” notion is a myth.

    Rudy’s positions and record are already known among most Republican primary voters and are factored in to the current polling.

    What We Can Expect
    Discrediting the commitment of the Mayor to run for President did not work. Telling Republicans that the Mayor’s positions on issues are unacceptable to primary voters does not work either.

    As we have seen the next line of attack is aimed at discrediting the Mayor’s character. This attack – while not surprising – should be treated for what it is – cheap and political.

    We expect polls to tighten as we move in to spring – such is the nature of the political process. While we are realistic about our expectations going forward, we are also pleased with where we are today and are confident our current support among Republican primary voters is strong.

    Los Angeles Times Watch: GrazerGate FLAP Part II

    martinezmarch23aweb

    Andrés Martinez, left, resigned as Los Angeles Times editorial page editor, saying he had been undermined by his publisher, David Hiller.

    New York Times: Los Angeles Times Editorial Page Chief Quits

    Andrés Martinez, the editorial page editor of The Los Angeles Times, resigned yesterday, saying he had been undermined by his publisher over what Mr. Martinez described as a “perception of a conflict of interest.”

    Mr. Martinez had helped select Brian Grazer, a Hollywood producer, as guest editor of a special edition of this Sunday’s opinion section, called Current. The paper reported yesterday that Mr. Martinez is in a romantic relationship with Kelly Mullens, a senior executive at the public relations firm that represents Mr. Grazer’s production company.

    The publisher, David Hiller, initially said he did not see a conflict, only the appearance of a conflict that could be handled with an editor’s note disclosing the relationship, said James O’Shea, the paper’s editor. But Mr. Hiller changed his mind yesterday after several staff members expressed their concern to Mr. O’Shea, and Mr. O’Shea spoke with Mr. Hiller. Yesterday, Mr. Hiller canceled the special edition.

    In a statement last night, Mr. Hiller said that “a potential conflict of interest had emerged” over Mr. Martinez’s relationship with Ms. Mullens. “We believe that this relationship did not influence the selection of Brian as guest editor,” he said. “Nonetheless, in order to avoid even the appearance of conflict, we felt the best course of action was not to publish the section.”

    When informed of the decision, Mr. Martinez resigned and took the unusual step of announcing his decision on a blog on the paper’s Web site. In a defiant note, he wrote that the paper had overreacted, that Mr. Grazer and Ms. Mullens “did nothing wrong” and that Mr. Hiller’s decision made his tenure “untenable.”

    There is the story and the FLAP which is a precis from yesterday’s post.

    Now, Andres Martinez STRIKES BACK.

    He blames not himself for an ethical gaffe but newsroom reporters who tattle-tailed. These reporters (and Martinez does name names) want the newsroom to influence the editorial pages.

    Go figure.

    Hell, the Los Angeles Times news stories have been biased and opinionated for years.

    The difference here?

    Someone from Spring Street finally spills the beans – so to speak.

    Hugh Hewitt refers to the HYPOCRISY of former Los Angeles Times Editor, John Carroll.

    Patterico adds his insight.

    Flap smiles with the vindicative countenance of a pseudo-journalist.

    Iran Watch: Iran Seizes British Sailors in Iraq Waters

    iranmarch232007aweb

    AP: Iran nabs British sailors in Iraq waters

    Iranian naval vessels seized 15 British sailors in Iraqi waters on Friday, the Ministry of Defense said.

    The British Navy personnel were “engaged in routine boarding operations of merchant shipping in Iraqi territorial waters,” and had completed a ship inspection when they were accosted by Iranian vessels, the ministry said.

    “We are urgently pursuing this matter with the Iranian authorities at the highest level and … the Iranian ambassador has been summoned to the Foreign Office,” the ministry said.

    A Pentagon official said the Britons were in two inflatable boats from the frigate H.M.S. Cornwall during a routine smuggling investigation, said the official, who spoke on condition on anonymity because he was not authorized to speak about the incident.

    So, is this a show of force as Iran President Ahmadinejad prepares to leave for New York and a Saturday address to the United Nations Security Council?

    A mistake or miscalculation?

    Or was this planned?

    iranmarch232007bweb

    Members of the British Royal Navy boat team patrol the Shatt al-Arab waterway that flows into the Gulf, December 2003. Some 15 British Royal Navy sailors were detained by Iranian navy vessels in the Gulf, the Ministry of Defence has said, adding that it was “urgently” seeking clarification from Tehran.

    And remember this is not the first time this has happened. There was a similar incident in 2004.

    In any case, Ahmadinejad will have alot to explain to Britain at the United Nations tomorrow.

    Stay tuned for updates……
