Changing cancer's environment to halt its spread

Wednesday, May 22, 2013

By studying the roles two proteins, thrombospondin-1 and prosaposin, play in discouraging cancer metastasis, a trans-Atlantic research team has identified a five-amino acid fragment of prosaposin that significantly reduces metastatic spread in mouse models of prostate, breast and lung cancer. The findings suggest that a prosaposin-based drug could potentially block metastasis in a variety of cancers.

The study team, led by Randolph Watnick, PhD, at Boston Children's Hospital, Vivek Mittal, PhD, at Weill Cornell Medical College and Lars Akslen, MD, PhD, at the University of Bergen, released their findings in the May issue of the journal Cancer Discovery.

The main cause of cancer mortality is not the primary tumor itself, but rather its spread?metastasis?to other locations in the body and subsequent organ failure. Previous studies by Watnick, a member of Boston Children's Vascular Biology Program, and others have shown that tumors capable of metastasis release proteins that help prepare new homes in distant organs for their metastatic progeny.

Watnick's lab has also previously shown that tumors that cannot metastasize release prosaposin. This protein activates expression of a second protein called thrombospondin-1, a potent anti-angiogenic factor, in tissues where metastatic tumor cells could potentially take root. Thrombospondin-1 makes these otherwise-permissive tissues resistant to metastasis.

"In the past, we've struggled to determine the source of thrombospondin-1 production," Watnick says. "We knew it was coming from the tumor microenvironment, normal cells adjacent to the sites of potential metastasis, but we could not tell if those cells were native to the microenvironment or had been recruited from the bone marrow."

Using mouse models of breast, prostate and lung cancer, Watnick and his colleagues confirmed through bone marrow transplant and gene knockout experiments that both metastatic and non-metastatic tumors induce cells from the bone marrow?specifically, monocytes expressing the Gr1 surface marker?to migrate to the lungs. However, non-metastatic tumors then trigger these monocytes to produce thrombospondin-1 by releasing prosaposin.

"Others have shown that tumors recruit monocytes to future metastatic sites, which help to set up a permissive environment for tumor cells to metastasize, " Watnick notes. "Our results suggest that non-metastatic tumors do the same thing, but instead of creating a permissive environment, the monocytes create a refractory environment by producing thrombospondin-1."

Watnick thinks this finding creates a window of therapeutic opportunity. "If we can trigger monocytes recruited by pro-metastatic tumors to produce thrombospondin-1 like those recruited by non-metastatic tumors, we will be able to hijack the mechanism by which tumors create metastasis-permissive sites to close the door on those sites."

Thrombospondin-1 itself, however, is too large to serve as a drug, and studies using shortened versions of the protein have not been promising. Watnick and his collaborators instead are focusing on prosaposin. To find the smallest part of prosaposin capable of activating thrombospondin-1, the team took an 80-amino acid region of prosaposin and whittled it down bit by bit until they isolated a five amino-acid peptide that could trigger thrombospondin-1 production as strongly as the full-length protein.

When administered in mouse models of metastatic cancer, this peptide significantly reduced metastasis compared to scrambled versions of the peptide (with the same amino acids but in different sequence), but only in mice with monocytes capable of producing thrombospondin-1.

Strikingly, Watnick and his collaborators also found that prostate cancer patients whose tumors expressed higher levels of prosaposin had significantly greater overall survival than patients whose tumors expressed low levels of prosaposin. Thus, with additional work, Watnick believes the prosaposin peptide could be the foundation for a tumor- and location-agnostic method of treating or preventing metastasis in patients with advanced cancers.

"The size of this peptide makes it ideal for drug development," Watnick says. "It's about as large as tyrosine kinase inhibitors such as Gleevec or Iressa, and could potentially be formulated in multiple ways for different types of cancer. I could also foresee using a therapeutic agent like this peptide as an adjuvant therapy, for example just as we now use chemotherapy or hormonal therapy for breast cancer."

Boston Children's Technology and Innovation Development Office (TIDO) has filed patent applications on these peptides, peptide derivatives and their uses. A start-up company is in the works.

Well: No Quick or Easy Choices

By almost any measure, Roseann Valletti?s reconstructive breast surgery was a success. Although it was a protracted process, involving some pain and a nightmarish nipple replacement, she is pleased with how she looks.

But she is uncomfortable. All the time. ?It feels like I?m wrapped up in duct tape,? said Mrs. Valletti, 54, of the persistent tightness in her chest that many women describe after breast reconstruction.

?They look terrific, to the eye,? added Mrs. Valletti, a teacher who lives Valley Stream, N.Y., and who learned she had early-stage cancer in both breasts five years ago. ?But it?s never going to feel like it?s not pulling or it?s not tight. It took me a while to accept that. This is the new normal.?

Last week the actress Angelina Jolie announced in The New York Times that she had had a double mastectomy in February after testing positive for a genetic mutation that put her at high risk for breast and ovarian cancer. She also had reconstructive surgery.

Her disclosure was lauded by some advocates as a bold move that will inspire women to be proactive, learn about their family histories and risks, and consider genetic testing.

At the same time, some breast surgeons are discomfited that some might infer from the article that reconstructive surgery is a quick and easy procedure, and worry that Ms. Jolie inadvertently may have understated the risks and potential complications.

For most patients, like Mrs. Valletti, breast reconstruction requires an extended series of operations and follow-up visits that can yield variable results. Some women experience so many complications that they just have the implants removed.

?We do not yet have the ability to wave a wand over you and take out breast tissue and put in an implant ? we?re not at ?Star Trek? medicine,? said Dr. Deanna J. Attai, a breast surgeon in Burbank, Calif., who is on the board of the American Society of Breast Surgeons.

Ms. Jolie said that she completed her reconstructive surgeries in nine weeks, but for many patients the process takes closer to nine months. ?Three months is probably a little unusual,? said Dr. Gregory R. D. Evans, in Orange, Calif., president of the American Society of Plastic Surgeons. ?I usually tell my patients it will take about a year.?

And it is major surgery. Even with the best plastic surgeon, breast reconstruction carries the risks of infection, bleeding, anesthesia complications, scarring and persistent pain in the back and shoulder. Implants can rupture or leak, and may need to be replaced. If tissue is transplanted to the breast from other parts of the body, there will be additional incisions that need to heal. If muscle is removed, long-term weakness may result.

A syndrome called upper quarter dysfunction ? its symptoms include pain, restricted immobility and impaired sensation and strength ? has been reported in over half of breast cancer survivors and may be more frequent in those who undergo breast reconstruction, according to a 2012 study in the journal Cancer.

?People have to understand it?s not a breeze,? said Geri Barish, president of 1 in 9: The Long Island Breast Cancer Action Coalition and a three-time survivor of breast cancer. ?I don?t want people to think this is the cure-all, that this is it, hurry up, run out and get the test and have your ovaries and breasts removed.?

Types of Reconstruction

An array of new techniques, each with its own risks and potential benefits, makes for bewildering options for women. The first choice in breast reconstruction is whether to have implants or to make the new breast from muscle or fat and skin taken from elsewhere in the body, often from the abdomen ? so-called autologous tissue transfer.

More plastic surgeons are familiar with implants, and the procedure is less expensive than tissue transfer. Of the 91,655 women who had reconstruction last year in the United States, a vast majority opted for implants, with 64,114 choosing silicone and 7,898 choosing saline, according to the American Society of Plastic Surgeons. Just over 19,000 women chose autologous tissue transfer.

Many surgeons believe silicone implants confer a more natural look than saline, despite a long-running controversy over their safety. The Food and Drug Administration allowed silicone implants back on the market in 2006, after studies showed they did not increase the risk of immune disease. A new type is filled with a thick gel that may pose less risk of leakage.

Whether they are silicone or saline, however, implants do not last a lifetime. As many as half need to be replaced or removed within 10 years, according to the American Cancer Society. The implants can rupture, cause infections and lead to pain. Scar tissue often forms around the implants, making the breast hardened or misshapen. Last year alone, there were 16,596 procedures done to remove breast implants.

Reconstruction may be started at the same time as the mastectomy, or later. Usually the first step is to place a so-called tissue expander under the chest muscle, which normally presses against the ribs. The surgeon injects saline into the balloonlike pouch at regular intervals several weeks apart to create space for the implant.

Eventually, the expander is removed and replaced with the implant. (Unlike breast tissue, which sits on top of the chest muscle, the implant is situated under the muscle, which holds it in place.) The process can take several months, longer if problems develop or the patient needs other treatment like radiation, which tends to damage the surrounding skin and make it less hospitable to an implant.

In autologous tissue transfers, muscle, skin or fat from another part of the patient?s body substitutes for an implant. Some surgeons believe this creates a more natural-feeling and natural-looking breast. There are several options.

The transverse rectus abdominis myocutaneous, or TRAM, flap procedure uses tissue and muscle from the lower abdomen to shape a breast mound. But the surgery weakens the abdominal area, and at Johns Hopkins Breast Center, the procedure has been abandoned because of the risk of hernias and abdominal bulges and limitations on lifting after surgery.

Instead, some surgeons now perform the deep inferior epigastric artery perforator, or DIEP, flap procedure, which uses only abdominal skin and tissue, not muscle, to create the breast. Both the TRAM and DIEP surgeries are lengthy procedures that can last 12 hours and can lead to a complication of necrosis, or tissue death, if there isn?t adequate blood supply, Dr. Attai said.

A third type of flap procedure relies on back muscle that is moved under the skin to the front of the chest, but this can weaken the back, shoulder or arm. In yet another procedure, the gluteal free flap, tissue and muscle from the buttocks are used to create a breast mound.

Simulating a Nipple

Reconstruction of the nipple has long been a challenge. Surgeons have used incision scar tissue or tissue taken from the groin or between the buttocks to craft nipples. Tattoos are also used to darken the areola, with 3-D tattoos that create the impression of a nipple.

With a nipple- and skin-sparing mastectomy, the surgeon removes all of the glandular breast tissue while preserving the skin, areola and nipple, much as one might scoop all the fleshy fruit out of an orange and leave the skin intact. This is the procedure Ms. Jolie had. Yet even when it is successful, the nipples usually lose sensation and are numb and cannot play the same role in sexual arousal as before surgery.

Residual breast cells may be left behind, and there is a concern that these may become cancerous. The American Society of Breast Surgeons has established a nipple-sparing mastectomy registry to track patient outcomes.

A potential complication of nipple-sparing surgery is necrosis of the nipple and areola. One recent study found that one-fourth of patients developed partial necrosis in the areola and nearby skin, and needed surgery to remove the dead tissue and to prevent infection.

The choices to be made in breast construction, or whether to have it at all, are highly individual.

?Some patients just don?t want more than one incision,? and want to avoid autologous tissue for that reason, Dr. Attai said. ?Other patients want to avoid having a foreign body inside them? and therefore opt against implants.

Many women say plastic surgeons push them to choose larger implants. Some women worry that function can be sacrificed for form in the reconstruction process, leading to restricted mobility and pain that limits everyday tasks like driving and sitting at a computer, as well as more vigorous activities like biking or skiing. While women should know about the options, ?all the options may not be good for you as an individual,? Dr. Attai said. It is wise to get several opinions, she added, because surgeons have their own preferred techniques and biases.

Bearing the Costs

Whatever procedure is chosen, infections are a common complication, requiring aggressive treatment with antibiotics and often surgery to remove implants. One 2012 study estimated infections occur in up to 35 percent of post-mastectomy reconstructive procedures.

Though rare, it is possible for cancer to occur or recur in a reconstructed breast, because some breast tissue remains. Recurrence happens in 1 percent to 5 percent of patients, according to Dr. Attai, as it does for women who have mastectomy without reconstruction. Recurring cancers can be somewhat easier to detect in breasts reconstructed with implants than with tissue transfer, she noted.

Though there has been concern that the nipple-sparing procedure might lead to more frequent recurrence of cancer, a recent review found that just 2.8 percent of patients experienced a recurrence over two years.

Cost is an important consideration. A federal law passed in 1998 required insurance plans and health maintenance organizations that pay for mastectomy to also cover the cost of reconstructive surgery. But the availability of plastic surgeons varies by region, and many do not accept insurance reimbursement.

Women may also face deductible payments as high as $10,000 with some plans, and those on Medicaid may face long waits because of a shortage of plastic surgeons who do breast reconstruction and accept this insurance.

While many women without cancer may now seek genetic testing for mutations in the BRCA 1 and BRCA 2 genes, they must meet certain criteria to be reimbursed by insurance, doctors say.

The criteria vary by insurer. United Health Care, for instance, covers testing if there is a known mutation in a family member or a first- or second-degree relative has developed breast or ovarian cancer. The test is expensive, about $3,000, and a negative test result for known genetic mutations does not necessarily mean a woman?s overall breast cancer risk is negligible, experts say.

?A lot of people with a strong family history of breast cancer discover they have no genetic mutation, at least not one we know about,? said Dr. Marisa Weiss, an oncologist and founder of Breastcancer.org. ?While they may be relieved they don?t have BRCA 1 or 2, obviously something is going on if a family is significantly affected.?

Uncertain Results

The test results can be ambiguous, finding what is called a ?variance of uncertain significance? or changes in the genetic code that are not well understood, said Dr. Susan M. Domchek, director of the Basser Research Center for BRCA at the University of Pennsylvania. Minority patients have a higher rate of such results, she said. The finding usually results in more frequent monitoring for cancer.

For all women, other options for reducing breast cancer risk include breast-feeding and avoiding both oral contraceptives and hormone therapy, Dr. Weiss said. Treatment with tamoxifen also appears to reduce the risk for BRCA mutation carriers.

None of these steps, however, will reduce the risk as significantly as prophylactic mastectomy and surgery to remove the ovaries, Dr. Weiss said.

Ms. Jolie has said indicated that she may undergo surgery to remove her ovaries. Ovarian cancer is so hard to detect that it often is found only at an advanced stage. But removal of the ovaries leads to immediate menopause and may adversely affect quality of life in drastic ways.

The multiplicity of treatment options and the persistent uncertainties about which is appropriate to an individual patient mean that decisions about preventive mastectomy have not grown easier, only harder. Many physicians are concerned that women, especially those traumatized by loss of a family member to cancer, may make hasty choices.

?We have had a rush of phone calls coming in with this idea, ?Should I be getting my mastectomy?? ? Dr. Domchek said. ?But every surgical procedure comes with potential complications, and we need to attempt to balance the risk and benefit.?


This post has been revised to reflect the following correction:

Correction: May 22, 2013

A capsule summary on Tuesday for an article about options in breast reconstruction surgery left the incorrect impression that the complex and often painful procedures described in the article referred to mastectomy. As the article explained, it is the elective reconstruction of the breast or breasts that is often a protracted process involving the risk of complications and variable results.

Google now offers Top Charts and visualization tool for trending topics

Google Trends reveals Top Charts and Hot Search visualization

Instead of waiting until the end of the year for Google's annual Zeitgeist, you can now find out what's trending in any given month with a new Top Charts feature from Google Trends. Updated monthly and going back to 2004, Top Charts is built on the Knowledge Graph, so it's smart enough to house related keywords under one term for more accurate rankings. For example, searches for "giants baseball" and "sf giants" would go toward pushing "San Francisco Giants" up the ranks in a sports-related chart. Right now there are more than 40 top ten lists with more than 140 time periods available for your perusal. In addition to the charts, the Trends team has also rolled out a new visualization tool for "hot searches" that displays trending topics in a large colorful layout -- as seen below, you can customize it to display up to 25 searches at a time that endlessly shift and refresh, thus consuming our attention for the entire day.

Are tit-for-tat sectarian killings enough to tilt Iraq back to war?

Bouts of sectarian fighting have worried observers many times over the past few years, but so far the worst has not come to pass.

By Dan Murphy,?Staff writer / May 20, 2013

Iraqi security force members inspect the site of a car bomb attack in Basra, 340 miles southeast of Baghdad, Iraq, Monday. Two car bombings in the southern city of Basra, killing and wounding dozens of people, police said. Iraq has seen a spike of attacks, including bombings hitting both Sunni and Shiite civilian targets over the last week.

After the death of more than 60 people in a series of car bombs today?targeting Iraq's majority Shiite community and weeks of escalating sectarian attacks, many are wondering if the country's simmering sectarian tensions will tumble once again into all-out civil war.

The situation in Iraq is bad enough, as the attacks today make clear. Reuters reported there were two deadly blasts in the southern, largely Shiite city of Basra; 30 deaths in seven different blasts targeting Shiite neighborhoods of Baghdad; and an attack on a bus carrying Shiite pilgrims near the town of Balad.?

This kind of violence, almost certainly carried out by Sunni militants, has ebbed and flowed for years in Iraq, without ever leading to large-scale sectarian bloodletting like that which occurred between 2005 and 2008, when tens of thousands of Iraqis were killed in fighting that transformed many of the mixed neighborhoods of Baghdad and other cities into entirely Shiite or Sunni enclaves. An Al Qaeda in Iraq attack on an important Shiite shrine in Samarra in February 2006?touched off?reprisal killings across the country.

Many have long wondered what event could be Iraq's next Samarra. The good news, if any good news can be taken from a society still as divided and violent as Iraq today, is that the general population and political elites have consistently shied away from the worst. And while the current flare-up is almost certainly going to claim more lives, the odds of all-out war are probably low, going by the experience of the past few years.

To be sure, the current situation is bad. Last Friday, at least 76 people were killed in bombs targeting predominantly Sunni areas in Iraq. Those attacks followed close on the heels of attacks against Shiites earlier in the week. In April, more than 700 people were killed, one of the highest monthly death tolls since 2008.

The government of Shiite Prime Minister Nuri al-Maliki has taken a hard line against Sunni protesters, with a deadly government raid on a protest encampment in the town of Hawija claiming at least 50 lives and infuriating the country's Sunni minority.

That protest encampment, like similar ones in Anbar province, was inspired by a widespread feeling among Iraqi Sunnis that they have been completely cut out of meaningful power by the country's Shiite majority, that Mr. Maliki is running the country in the interest of his sect rather than all citizens, and that the security forces commit human rights abuses with impunity.

While the worst of Iraq's fighting ended years ago, the national reconciliation that the US predicted would follow never occurred, leaving Iraq volatile and prone to violence. It has remained one of countries most beset by terrorism,?and added to that volatile mix is the civil war in Syria, with many members of Al Qaeda in Iraq joining the fight against Syrian President Bashar al-Assad.?

What's more, powerful Sunni leaders in Anbar province ? which borders Syria and was the center of the insurgency during the US occupation ? are being hounded by the central government (fairly or unfairly it's hard to say). Joel Wing has a good roundup on Sunni leaders in Anbar province, and their various recent conflicts with the central government's security forces. Ominously, a number of the people he discusses had been involved in fighting Sunni insurgents on the side of the government and US forces just a few years ago.? ?

"The recent raids, kidnappings, and the end of the call for talks with the authorities can only add to this growing fire," Wing writes. "Even if the mainstream protest movement like the one in Ramadi attempts to remain peaceful, it is apparent that more and more people in the governorate are at least open to the passive if not active support for attacks upon the security forces."

With all this, it's pretty easy to predict the worst. But Iraqis were so badly scarred by the sectarian civil war, with so much lost on every side, that it's hard to imagine the wildfire catching again soon. While average Iraqis have suffered due to a weak economy, both Shiite and Sunni political leaders have profited handsomely from high oil prices in recent years, and have little to gain from all-out warfare that would almost certainly end in the same result as last time: with the country's majority Shiite population still in the driver seat.?

Make no mistake. Iraq's situation is grim. But the country has repeatedly pulled back from the brink in recent years. And there's a good chance that it will again.

Kyrgyzstan bent on evicting US air base in 2014

BISHKEK, Kyrgyzstan (AP) ? Kyrgyzstan's president has reaffirmed that next year the Central Asian nation will evict the U.S. air base that supports military operations in nearby Afghanistan.

President Almazbek Atambayev has repeatedly pledged to shut the Manas Transit Center next year, dismissing U.S. assumptions the base would remain in exchange for higher rent. The United States pays $60 million annually for the base.

Atambayev said Tuesday the Kyrgyz Cabinet had drafted a bill on the base closure and submitted it to parliament. He said Kyrgyzstan would compensate for the loss of revenue through other economic projects.

All U.S. troops moving in and out of nearby Afghanistan travel through Manas. Large numbers of troops are set to flow through the facility as part of the withdrawal of most international troops next year.

Top figures barred from Iran's June ballot

TEHRAN, Iran (AP) ? Iran's election overseers removed potential wild card candidates from the presidential race Tuesday, blocking a top aide of outgoing President Mahmoud Ahmadinejad and a former president who revived hopes of reformers.

Their exclusion from the June 14 presidential ballot gives establishment-friendly candidates a clear path to succeed Ahmadinejad, who has lost favor with the ruling clerics after years of power struggles. It also pushes moderate and opposition voices further to the margins as Iran's leadership faces critical challenges such as international sanctions and talks with world powers over Tehran's nuclear program.

The official ballot list, announced on state TV, followed a nearly six-hour delay in which the names were kept under wraps. That raised speculation that authorities allowed some time for appeals by the blackballed candidates and their backers to Supreme Leader Ayatollah Ali Khamenei, who has final say in all matters.

But the official slate left off two prominent but divisive figures: former President Akbar Hashemi Rafsanjani and Ahmadinejad protege Esfandiar Rahim Mashaei. The decision also appeared to remove many potential surprise elements in the race, including whether Rafsanjani could revitalize the reform movement or if Ahmadinejad could play a godfather role in the election with his hand-picked political heir.

Instead, those cleared by the candidate-vetting Guardian Council included eight high-profile figures considered firm and predictable loyalists to the ruling Islamic establishment such as former Foreign Minister Ali Akbar Velayati, Tehran Mayor Mohammad Bagher Qalibaf and Iran's top nuclear negotiator, Saeed Jalili.

Any of the choices would create a possibly seamless front between the ruling clerics and presidency after years of political turmoil under Ahmadinejad, who tried to challenge the theocracy's vast powers to make all major decisions and set key policies. Iran's presidency, meanwhile, is expected to convey the ruling clerics' views on the world stage and not set its own diplomatic agenda.

Mashaei called the decision unfair and said he will appeal to Khamenei. "God willing this will be resolved," semiofficial Fars news agency reported late Tuesday.

Rafsanjani did not comment, but his supporters denounced the decision on social media.

While the election is not expected to bring major shifts in Iran's position on its nuclear program ? which Tehran insists is peaceful despite Western fears it could lead to atomic weapons ? it could open opportunities to renew stalled talks with a six-nation group that includes the U.S.

On Tuesday, Foreign Ministry spokesman Abbas Araqchi said Iran's nuclear stance will "not change either before or after the election."

The ballot rejection of Mashaei brought little shock.

He has been badly tarnished by Ahmadinejad's feuds with the ruling clerics. Hard-liners have denounced Mashaei as part of a "deviant current" that seeks to undermine the country's Islamic system ? which made ballot approval highly unlikely.

This leaves Ahmadinejad politically orphaned going into the final weeks in office. He still has significant public support and could try to bargain with other candidates or break away and start his own political movement.

Few powerful voices came to Mashaei's defense in a sign of Ahmadinejad's fallen fortunes. But the case for Rafsanjani was more complicated.

His unexpected decision for a comeback bid ? 16 years after leaving office ? jolted hard-line foes and was cheered by beleaguered reformists and liberals after years of crackdowns.

Rafsanjani faced a barrage of attacks in the past week from powerful critics who suggested the 78-year-old does not have the stamina for the presidency and is disgraced for criticizing the heavy-handed tactics used to crush protests following Ahmadinejad's disputed re-election in 2009.

Rafsanjani's youngest daughter, Faezeh, was released from jail in March after serving a six-month sentence in connection with the postelection chaos. His middle son, Mahdi, also is to stand trial in coming weeks for his alleged role in the riots.

Late Monday, authorities closed down the Tehran headquarters of Rafsanjani's youth supporters.

But Rafsanjani still carries a legacy with a sweeping reach.

Moderates see him as a pragmatist who can deal deftly with the West and use his skills as patriarch of a family-run business empire to help repair Iran's economy, battered by sanctions and mismanagement. Others, even ideological foes, respect his high-profile role in the 1979 Islamic Revolution as the closest confidant of its spiritual leader, Ayatollah Ruhollah Khomeini.

In a sign of possible lobbying on Rafsanjani's behalf, he received apparent support from some influential members of the Assembly of Experts ? the only group with the power to dismiss the supreme leader. Rafsanjani was pushed out as the group's chairman after failing to get enough support to leverage possible concessions from Khamenei on the 2009 postelection clampdowns.

One member, Ayatollah Mohieddin Haeri Shirazi, sent a letter to Khamenei saying "omitting a prominent figure from the election was incompatible" with giving wide choices to voters, the semiofficial ISNA news agency reported.

Another assembly member, Ayatollah Mohammad Vaez Mousavi, told the semiofficial ILNA news agency that Rafsanjani's age is not a weak point and many Iranian leaders "accepted responsibilities when they were quite old."

Prominent political analyst Saeed Leilaz said the "intensified defamation campaign" suggested worry among hard-liners that Rafsanjani had a real potential to rally moderates and others and win the election.

"What matters today is who can save the country's economy," he said, "Who has a plan to take Iran away from isolation and improve living conditions."

URBANA - A National Science Foundation (NSF) planning grant will help establish the Center for Advanced Research in Drying (CARD), a joint program of the University of Illinois at Urbana-Champaign and Worcester Polytechnic Institute (WPI) in Worcester, Mass.

"CARD will be devoted to research in drying moist, porous materials such as food and other agricultural products; forestry and paper products; chemical products; textiles; and biopharmaceuticals," said Hao Feng, a U of I professor of food science and human nutrition and the Illinois site director.

According to Feng, the main focus of the research will be to develop products, processes, designs, and strategies to reduce energy usage and cost in these energy-intensive industries. Added benefits include improvements in product quality and enhancement of sustainable practices.

"In other words, CARD will help companies reduce their carbon footprint," he said.

The grant was funded under NSF's Industry/University Cooperative Research Center (I/UCRC) program. I/UCRCs were developed to encourage collaboration between companies and universities in the development of novel processes and methods to solve grand challenges confronting our nation, said Irfan Ahmad, co-principal investigator of CARD and executive director of the U of I Center for Nanoscale Science and Technology.

"NSF provides seed funding to establish the center, and companies provide broader funding for industrially driven research projects. These projects are prioritized by an industry advisory board (IAB) comprising the member companies, and results are shared with all members," Ahmad added.

Jamal Yagoobi of WPI's Department of Mechanical Engineering will be the lead principal investigator/project director for CARD; Cosme Furlong-Vazquez will be the site co-director at WPI; and Hao Feng will be the site director at Illinois.

As the lead site for the program, WPI will host the initial meeting with both company and NSF representatives on Aug. 13-14.

URBANA - A National Science Foundation (NSF) planning grant will help establish the Center for Advanced Research in Drying (CARD), a joint program of the University of Illinois at Urbana-Champaign and Worcester Polytechnic Institute (WPI) in Worcester, Mass.

"CARD will be devoted to research in drying moist, porous materials such as food and other agricultural products; forestry and paper products; chemical products; textiles; and biopharmaceuticals," said Hao Feng, a U of I professor of food science and human nutrition and the Illinois site director.

According to Feng, the main focus of the research will be to develop products, processes, designs, and strategies to reduce energy usage and cost in these energy-intensive industries. Added benefits include improvements in product quality and enhancement of sustainable practices.

"In other words, CARD will help companies reduce their carbon footprint," he said.

The grant was funded under NSF's Industry/University Cooperative Research Center (I/UCRC) program. I/UCRCs were developed to encourage collaboration between companies and universities in the development of novel processes and methods to solve grand challenges confronting our nation, said Irfan Ahmad, co-principal investigator of CARD and executive director of the U of I Center for Nanoscale Science and Technology.

"NSF provides seed funding to establish the center, and companies provide broader funding for industrially driven research projects. These projects are prioritized by an industry advisory board (IAB) comprising the member companies, and results are shared with all members," Ahmad added.

Jamal Yagoobi of WPI's Department of Mechanical Engineering will be the lead principal investigator/project director for CARD; Cosme Furlong-Vazquez will be the site co-director at WPI; and Hao Feng will be the site director at Illinois.

As the lead site for the program, WPI will host the initial meeting with both company and NSF representatives on Aug. 13-14. Faculty from the U of I College of Agricultural, Consumer and Environmental Sciences (ACES) and the U of I College of Engineering will participate. Two IAB meetings will be held each year.
