While there have been major advances in the detection, diagnosis, and treatment of tumors within the brain, brain cancer continues to have a very low survival rate in part to high levels of resistance to treatment. New research published in BioMed Central's open access journal Journal of Nanobiotechnology has used Sendai virus to transport Quantum Dots (Qdots) into brain cancer cells and to specifically bind Qdots to epidermal growth factor receptor (EGFR) which is often over-expressed and up-regulated in tumors. By molecular-labeling cancer cells this nanoparticle technology could be used to aid diagnosis.

Qdots are tiny fluorescent particles, smaller than a virus, and over 1000 times smaller than a cell, which can be linked to biological molecules, such as antibodies. Once linked, the fluorescence would make it easy to find which cells contain the protein the antibody recognizes, and where in the cell this protein is located. However there have been problems getting the Qdots into cells without them clumping, or being packaged in to endosomes, and excreted from the cells as waste.

Researchers from the City College of New York have overcome this problem by coating the Qdots in lipid and protein coats based on Sendai virus. Prof Maribel Vazquez explained, "While cells have complex defense mechanisms to protect themselves against attack, viruses have evolved ways to fool the cell into letting them in. We were able to exploit these mechanisms by fusing inactivated mouse parainfluenza virus with liposomes containing Qdots. The Qdots were in turn attached to an antibody against EGFR. So, once inside the cell, the Qdot-antibody complexes were able to bind to the receptor and the amount of bound complex could be monitored by measuring Qdot fluorescence."

This study looked at the level of EGFR as a marker for cancer but the Qdots could be attached to any antibody. Antibody-Qdot sets would allow rapid identification of different cancer types, determine potential chemotherapy resistance, and lead a more individualized treatment plan.

Nano-technology uses virus' coats to fool cancer cells

Remote-controlled chip implant delivers bone drug

WASHINGTON (AP) — Medication via remote-control instead of a shot? Scientists implanted microchips in seven women that did just that, oozing out the right dose of a bone-strengthening drug once a day without them even noticing.

Implanted medicine is a hot field, aiming to help patients better stick to their meds and to deliver those drugs straight to the body part that needs them.

But Thursday's study is believed the first attempt at using a wirelessly controlled drug chip in people. If this early-stage testing eventually pans out, the idea is that doctors one day might program dose changes from afar with the push of a button, or time them for when the patient is sleeping to minimize side effects.

The implant initially is being studied to treat severe bone-thinning osteoporosis. But it could be filled with other types of medication, said co-inventor Robert Langer of the Massachusetts Institute of Technology.

"It's like 'Star Trek,'" said Langer, who co-authored the study appearing Thursday in the journal Science Translational Medicine. "Just send a signal over a special radio wave, and out comes the drug."

Today's medication implants continuously emit their drugs until they run dry. One example is a dime-sized wafer that oozes chemotherapy directly onto the site of a surgically removed brain tumor, targeting any remaining cancer cells. Another is a contraceptive rod that is implanted in the arm and releases hormones to prevent pregnancy.

A next step would be more sophisticated implants that release one dose at a time, programmable to skip or add a dose as needed, said biomedical engineer Ellis Meng of the University of Southern California. Meng wasn't involved with the MIT study but also is developing this kind of technology, and called Thursday's report "an important milestone."

Women with severe osteoporosis sometimes are prescribed daily injections of the bone-building drug teriparatide, known by the brand Forteo. But many quit taking it because of the hassle of the shots.

In the study, the microchip held doses of that drug inside tiny wells that are sealed shut with a nano-thin layer of gold. Sending a wireless signal causes the gold on an individual well to dissolve, allowing that dose to diffuse into the bloodstream, Langer explained.

In a doctor's-office procedure, the microchip was implanted just below the waistline into eight women with osteoporosis in Denmark. Testing found one microchip wasn't responding to the signals. The other seven women had their implants programmed to automatically emit a once-a-day dose beginning eight weeks later.

The chips could have begun working right away, said Robert Farra, CEO of MicroCHIPS Inc., a Massachusetts company that has licensed the device and funded the study. But animal research showed a scar tissue-like membrane forms around the pacemaker-sized implant. So he waited until that blockage formed to signal the first of 20 once-a-day doses to begin, to see if the drug could get through.

Blood testing showed the implant delivered the drug as effectively as the women's usual daily injections, and the device appeared to be safe, the researchers reported.

It will take large-scale studies to prove the implant works as well as the long-used shots, cautioned osteoporosis specialist Dr. Ethel Siris of New York-Presbyterian Hospital/Columbia University.

"They're a long way from proving that this mode of administration is going to work," she said. But it's an intriguing idea because "it's daunting to have to take a daily shot."

Farra said his company hopes to begin a larger-scale test, using a chip that can hold 365 doses, in 2014. While doses of this osteoporosis medicine typically aren't adjusted, he said, the eventual goal is for patients to carry a cell phone-sized device that would provide wireless feedback to the doctor who programs their implants.

Osteoporosis patients could soon ditch daily injection pens for an implantable microchip that releases medication at the push of a remote-controlled button, reports a new study appearing 16 February 2012 in the journal Science Translational Medicine.

The clinical trial, composed of a group of women with osteoporosis in Denmark, is the first to test a wirelessly controlled microchip capable of releasing drugs into the body at any time.

?Patients will be freed from having to remember to take their medication and don?t have to experience the pain of multiple injections,? said Robert Farra, President and Chief Operating Officer of MicroCHIPS, Inc., the Massachusetts-based company behind the device. Farra is a co-author of the study, along with colleagues from MIT, Harvard Medical School, OnDemand Therapeutics Inc and Case Western Reserve University.

Unlike most drug delivery devices, which release small amounts of drug slowly over time, the microchip releases medication on command from an external wireless device. This controlled system gets medicine into the bloodstream quickly, similar to an injection.

?Physicians will be able to seamlessly adjust their patients? therapy using a computer or cell phone,? said Farra.

The authors figure the microchip may be a more appealing and possibly cheaper alternative to long-term use of prefilled daily injection pens.

Patients with severe osteoporosis often have to give themselves daily injections of medication that requires refrigeration. Aside from the psychological burden of daily injections, older people may have arthritis or other problems that make injections physically difficult.

Moreover, since osteoporosis is a ?silent? disease ? affected individuals don?t feel better or worse as their bone density decreases ? many patients simply stop taking medication to avoid the hassle of daily injections.

The implant could help circumvent the high drop off in compliance and dramatically boost the quality of life for millions of osteoporosis patients. The device may also be useful for treating other chronic diseases like multiple sclerosis, heart disease or even cancer.

Roughly the size of a pacemaker, the device holds daily doses of a drug inside tiny wells that pop open either on a pre-programmed schedule or via a wireless signal.

?The drugs are in different wells. Each of these wells is covered by a nano-thin layer of gold which protects the drug for years if needed and prevents it from being released,? said Robert Langer, Professor at MIT and co-author of the Science Translational Medicine paper.

Sending a wireless signal to the well causes the gold to dissolve, freeing medication into the bloodstream.

Adapting microchip technology for human use is no small feat. The team first had to figure out a way to seal each reservoir airtight at room temperature. They developed a special compression welding process designed to provide a long-term seal. The researchers also developed the gold layer, which is strong enough to protect the contents of each reservoir, but thin enough to dissolve on command.

Despite the microchip?s proven ability to deliver drugs in the lab, once it was implanted into animals, a fibrous collagen-based membrane tended to develop around the device.

The researchers were concerned that this fibrous tissue could potentially slow down the absorption of medication, and one of the aims of this study was to determine if the membrane decreased effectiveness.

The researchers implanted the microchip just below the waistline, into seven women between the ages of 65 and 70. The procedure can be performed in a doctor's office with local anesthetic.

Tracking the women for 12 months, the team showed that the implant delivered the drug teriparatide just as effectively as daily injections, although the fibrous membrane did form around the device. Treatment improved bone formation and reduced the risk of bone fracture, as evidenced by the presence of biochemical markers signaling bone formation, bone mass and bone resorption.

?And there is much less variation from dose to dose than injections, so it's safer and more effective in that sense,? Langer said. The chip was removed from participants at the end of the one-year treatment.

The company hopes to make the device available for mainstream use in five years.

Tai chi helps ease symptoms of Parkinson's disease, study says

NEW YORK — The ancient Chinese exercise of tai chi improved balance and lowered the risk of falls in a study of people with Parkinson's disease. Symptoms of the brain disorder include tremors and stiff, jerky movements that can affect walking and other activities.

Medications and surgery can help, and doctors often recommend exercise or physical therapy.

Tai chi (ty-CHEE'), with its slow, graceful movements, has been shown to improve strength and aid stability in older people, and has been studied for a number of ailments. In the latest study, led by Fuzhong Li of the Oregon Research Institute in Eugene, tai chi was tested in 195 people with mild-to-moderate Parkinson's.

The participants attended twice-weekly group classes of either tai chi or two other kinds of exercise — stretching and resistance training, which included steps and lunges with ankle weights and a weighted vest.

The tai chi routine was tailored for the Parkinson's patients, with a focus on "swing and sway" motions and weight-shifting, said Li, who practices tai chi and teaches instructors.

After six months of classes, the tai chi group did significantly better than the stretching group in tests of balance, control, walking and other measures. Compared with resistance training, the tai chi group did better in balance, control and stride, and about the same in other tests.

Tai chi training was better than stretching in reducing falls, and as effective as resistance training, the researchers reported. The improvements in the tai chi group continued during three months of follow-up.

Li said the study showed tai chi was safe. It's easy to learn, and there's no special equipment, he added.

"People are looking for alternative programs, and this could be one of them," he said.

Estimates vary, but at least 500,000 people in the United States have Parkinson's.

The findings are in Thursday's New England Journal of Medicine. The study was paid for by the National Institute of Neurological Disorders and Stroke.

Dr. Chenchen Wang, who is studying tai chi for arthritis and fibromyalgia, said the results of the Parkinson's research are "dramatic and impressive." She heads the Center for Complementary and Integrative Medicine at Tufts Medical Center in Boston.

One of the study's strengths: Researchers could measure the results directly instead of relying on the patients' own reports, she said. But a placebo effect can't be totally discounted, she said, because the participants knew which exercise program they were assigned and that could have influenced results.

Local biotech company hopes save lives by focusing on microscopic cancer cells

Health care is dying for innovation and IVDiagnostics has no shortage of game–changing ideas to transform medicine and save lives.

"My wife has survived for 22 years with three bouts of cancer, and she is my personal inspiration," says Valparaiso resident and IVDiagnostics CEO Frank Szczepanski.

"If you believe in the current paradigm of using an imaging test to determine if you have a solid tumor, in our opinion, that's too late. Wouldn't you rather find the cancer when it's microscopic?"

IVDiagnostics was formed to develop, test and market more effective diagnostic tools for rare circulating tumor cells (CTC), which find their way to a distant organ to start new cancer growth. CTCs are considered among the major causes for mortality among cancer patients, Szczepanski says.

With this company's technology, doctors will be able to perform a real–time diagnosis of a patient's CTCs without drawing blood.

The company's cofounders are Frank's brother, Tom, of East Chicago, and Wei He, who is a doctor of analytical chemistry and the team's lead scientist. "Our No. 1 goal is to save lives," Frank Szczepanski says.

What's inside

IVDiagnostics is Szczepanski's ninth start–up company. Several years ago, he met Wei He who suggested a tactic of "in vivo," or monitoring blood inside the body. Cells of two to 10 microns can be detected.

About 25 percent of the body's blood can be optically scanned in 30 minutes. The absence of needles is a benefit cancer patients are enthusiastic about, Szczepanski said.

The test, referred to as a liquid biopsy, also is more accurate and sensitive than surgical biopsies. "Once this gets to market there won't be a single doctor who won't want this for a patient," Szczepanski said.

Repeated needle sticks common in intravenous disease treatment causes problems such as hardening of the arteries, bruising and even missed chemotherapy if clinicians can't draw blood on any given day.

The test also doesn't require administering toxic substances into the body such as radioactive materials used in some forms of images. "They have to light you up so they can diagnose and those isotopes stay in the body," he said.

Innovation in medicine

The company also is developing a molecular test for pancreatic cancer, one of the hardest for early detection, which identifies mutations in DNA or deficiencies in certain proteins.

That test could be available in one year and also could be used as a susceptibility test. "Steve Jobs' family should have this test because they are undoubted carrying the mutation," he says. "It's just a matter of who has it. It's scary because mutations can skip generations. If it skips you, good for you, but your children may end up getting it."

Szczepanski says in the future both testing devices will handheld and wireless. "You can imagine the possibilities," he says.

Patients could take the device with them so they could be monitored at home and wouldn't have to wait for routine consultations or follow–up visits.

IVDiagnostics' general target is metastatic cancer such as breast, lung, prostate, melanoma and ovarian. The company is doing live tissue sample testing now and with proper funding the entire portfolio of tests could be available within three years.

Slow burn sustainability

It takes awhile for many young firms to generate cash and survival depends on having an adequate supply of cash on hand to meet expenses.

The company was originally self–funded and in a three–year period received more than $1.5 million in seed capital from two rounds of friends and family funding. It also received $400,000 in federal funding from the National Institutes of Health and the National Cancer Institute.

IVDiagnostics was recently named The Revolutionary Technology Company of the Year by the Indiana Small Business Development Center. "The time it takes to do the research and development before a product can be marketed is hugely important," says Bill Gregory, of the Northwest Indiana SBDC.

"You have to be able to raise all sorts of additional revenue and capital and find skilled people. They've had to do a lot to get where they've gotten. It takes passion, experience, innovation and patience to do work in biomedicine."

In Indiana, fund investments steadily fell from $14.6 million in 2007–08 to just $6.6 million in 2009–10. "That is the legacy of this recession – not one or two missed companies, but a changed capital market," said David Johnson, president and CEO of BioCrossroads, a statewide life sciences organization.

Private venture capital invested in life sciences within Indiana, from 2002–10 was $277 million.

Some of the partners are not taking a salary, but Szczepanski said the company is good at managing its burn rate.

Burn rate refers to the rate at which a company uses up its supply of cash over time and tells investors whether a company is self-sustaining. Companies with high cash burn rates can turn an investment into ashes.

Many other biotechnology firms have a burn rate of about $2 million per year, he said. IVDiagnostics' rate is 25 percent of that or roughly $500,000 annually.

"We have many people on our team that are sacrificing and taking equity instead of cash," said Szczepanski. "But we can do that for only so long."

Looking for angels

The next major round of financing hopes to secure $3 million to $5 million from angel group or venture capitalists to cover the cost of clinical trials and additional research and development.

IVDiagnostics is poised for exponential growth because of the known demand for its testing. A single community hospital has anywhere from 500 to 1,000 new cancer patients yearly and each patient could need monitoring up to five times annually.

Within five years, the company could generate $100 million in revenues. The anticipated cost to patients for the test would be $400 to $800 compared to $5,000 to $8,000 for a CAT scan.

Monitoring patients five times a year with IVDiagnostics technology compared to twice a year for an imaging test would result in annual savings of $12,000 to $15,000 per patient annually.

Worldwide, $300 billion is spent on cancer diagnosis and the United States market alone spends $124 billion. "If we can save half that amount because of better molecular medicine, the savings to the health care industry are huge," Szczepanski says.

Restructuring Indiana's economy

Szczepanski is a leading entrepreneur who has been involved in nine startups in the last 20 years. He looks to the future and considers himself a successful technologist.

"Unless you have the vision, inspiration and perseverance to do something new, you're not an entrepreneur," he said. "Everyone in our company shares a commonality that this is a noble cause."

Indiana's position as a life science leader is clear and has long been thought of as the one of the state's bright economic spots.

It has weathered the recession well but tighter capital markets threaten to starve the risky process of medical innovation. That challenge is predicted to be permanently harder although the industry is still producing jobs.

The Indiana Business Research Center reported life science industry employment grew 2.9 percent between 2001 and 2007 compared to 0.2 percent for total employment and a loss of 1.9 percent for manufacturing.

According to BioCrossroads, total employment in life sciences in Indiana has held steady at around 50,000 jobs since 2007. In 2010, there were 854 establishments generating $4.3 billion in wages. The average Indiana life sciences wage was $86,537 which is more than twice the state's average wage.

The value of Indiana's life science exports totaled $9.0 billion in 2010, up from $5.0 billion in 2006.

Szczepanski sees the life sciences as the changing face of Indiana's economy – from a steelmaker in a hard hat and farmer on a tractor to a scientist in a white lab coat with a microscope.

The most important factors for success is an experienced and educated workforce. The Hoosier state is a major generator of life science graduates, so it has labor pool and an industry that can fight the brain drain of college graduates.

Szczepanski's vision for Northwest Indiana is for the university and medical communities to collaborate and form a center for advanced cancer research to accelerate molecular medicine.

"We're looking at a new form of manufacturing," he says. "The footprint for Northwest Indiana can change its focus on steelmaking and agriculture to nano particle production and biomedical equipment which brings a higher level of jobs. It can be a motivator in our state for a different economic force to switch from raw materials processing to biotech."

OU nanoparticle research may fight cancer cells

New research using nanoparticles is on the frontline on the war against cancer

OU researchers are hoping extremely tiny particles outfitted with medicine can be used to discover and fight cancer more effectively.

Dr. Rajagopal Ramesh, who has worked at the OU Health and Sciences Center for the past year and a half as a researcher, is creating and testing nanoparticles on lung cancer cells to discover new ways to fight cancer.

AT A GLANCE

Nanoparticles

The particles Dr. Rajagopal Ramesh and the OU Health Sciences Center researchers are working with are 18 nanometers in size. A nanometer is one-billionth of a meter.

The nanoparticles, which are billionths of a meter in size, are composed of an iron core and a gold layer covered in Cetuximab, a U.S. Food and Drug Administration approved antibody, Ramesh said. The particles are introduced into the body intravenously, according to a peer-reviewed research article in the science journal PLoS ONE.

The particles’ size allows them to maneuver through the body’s smallest blood vessels with greater ease than traditional drugs, the iron core allows the use of MR, and the golden surface helps medicine adhere to the particle while having optical properties that illuminate under laser light, Ramesh said.

Varying on the density of the gold under laser light, the particles will illuminate in shades of blue, red or green. For example, if there was a tumor infested with those particles, a doctor could shine a laser over the surface and identify the edges of a tumor, Ramesh said. Without this technology, doctors could surgically extract a portion of a tumor but leave superfluous cancer cells remaining around the edge.

The initial purpose of the research was to curb the collateral damage done by chemotherapy to healthy cells and to increase the duration of drug circulation in the body, Ramesh said.

When the size of the capsule for this therapy was brought down to the nano level, it became easier for the drug to pass through the blood vessels and have made a greate impact on tumors, Ramesh said.

The materials used for these drugs can come from a wide range of substances. Ramesh and his team have been using an iron core in the particles so they will show up using MRI.

Traditionally, to assess the effectiveness of a treatment, patients will prepare for days before undergoing an MRI, which is costly and time consuming, Ramesh said. That time can be better spent, and a few days are often the difference between life and death in cancer treatment, Ramesh said. The nanoparticles’ iron core makes it possible to perform an MRI without the days of preparation to immediately establish a treatment’s effectiveness, Ramesh said.

“What we are coming into now is the age of personalized medicine,” Ramesh said. “All cancers are unique. One person’s lung cancer is different than another person’s lung cancer.”

The gold serves other benefits as well. When gold is hit with light, it generates heat. By raising the temperature of the particles, the cancer can be burned away. Also, the golden surface is conducive for attaching antibodies, which help fight the cancer, Ramesh said. The Cetuximab antibody essentially starves cancer cells by not allowing them to receive the signals they need to grow.

The research is promising, but don’t expect the procedure to be on the market anytime soon, Ramesh said. There are many more steps to take and more research to be done before this can move to human trials, and after that, there is the hurdle of getting approval from the Food and Drug Administration.

Nano tech is subject of pub talk

Informal lecture will take place at Calapooia Brewing Co. in Albany

University of Oregon scientist David C. Johnson will take the minuscule world of nanotechnology on the road to Albany for an informal “science pub” at 6:30 p.m. Wednesday, Feb. 8, at Calapooia Brewing Co., 140 Hill St. N.E.

In his talk, “Nanotechnology: Unveiling the big world of the very small,” Johnson will describe how materials barely a billionth of a meter in size are about to revolutionize such things as computer technology, renewable energy, medicine and building materials.

The event is open to the public. Admission is free, but visitors will be responsible for the costs of their food and beverages.

Visitors under age 18 are welcome; however, a guardian or other responsible adult should place their food and beverage orders.

Science pubs originated in the 1990s in the United Kingdom and have since spread in popularity across the United States, with more than 150 cities hosting these informal lectures combined with food and drink, according to USA Today in December.

The National Science Foundation-supported Center for Sustainable Materials Chemistry — led by researchers at the UO and Oregon State University — is sponsoring the Albany science pub.

Johnson, a center co-director responsible for educational efforts, is the UO’s Rosaria P. Haugland Chair in Pure and Applied Chemistry.

He joined the UO faculty in 1986, and takes a non-traditional approach to chemical synthesis that has resulted in the development of many new materials with practical applications.
