Stem cell treatment for tendon, cartilage repair gains momentum

The use of stem cells to repair tendon and cartilage damage in horses is gaining momentum, with a British company saying its has successfully used it in the treatment on 300 performance horses.

The company behind it is VetCell Bioscience Ltd, set up by Britain's Royal Veterinary College in 2002.
Similar success is being enjoyed by researchers at Colorado State University's Equine Orthopaedic Center, reported on Horsetalk on January 6: http://www.horsetalk.co.nz/news/0601/003.shtml
The Colorado University's center, headed by New Zealand-born Dr Wayne McIlwraith, is among a handful of medical sites pioneering the revolutionary approach to treating equine joint injuries - ligament, tendon or bone fractures - with stem cells.

The London-based Vetcell is reportedly now going from strength to strength, and the firm says some of the most devastating injuries and diseases of performance horses are now treatable thanks to the therapy. Stem cells, for the first time, offer the prospect of a return to a fully functional tendon.

Like human athletes, competitive horses are vulnerable to joint injuries, especially tendon. Performance horses, like human athletes, are often pushed to their limits and this can lead to tendon or ligament injury. Injury to tendons is healed by extensive scar tissue, which limits the tendon?s normal role. The scar tissue impairs movement and is stronger than normal tendon, so does not stretch in the same way as normal tendon. In turn, this is likely lead to further lameness.

But, using the new technique to reduce the scar tissue formation caused by injury, and even regenerate damaged tendons, which is notoriously difficult in horses, can lead to complete recovery. The stem cell treatment is unique as it uses tissues to grow more tendon-like cells.
VetCell scientists are now working on revolutionary treatments to speed up human biological healing processes with stem cells. It is possible that similar repair mechanisms can be instituted in humans.
Greg McGarrell, CEO of VetCell, describes his firm as "a real zero to hero biotechnology company", built on a "shoe string".
"Our success is largely due to the cutting edge research at the Royal Veterinary College being combined with the knowledge of professional city people. This means that VetCell has had a commercial focus right from the start. While universities are keen to create spin-out companies, far too few of these become successful businesses. A key problem with spin-outs is that they lack good business management.

Mexican clinic where King died known for alternative treatments

ELLIOT SPAGAT
Associated Press
ROSARITO BEACH, Mexico - The Mexican clinic where Coretta Scott King died Tuesday was known for providing alternative treatments to patients with incurable diseases.
King, 78, suffered a serious stroke and heart attack last year, but her family and clinic employees declined to release any information about her treatment at the Santa Monica Health Institute.

Bishop T.D. Jakes of The Potter's House church in Dallas said he helped King get to Mexico, but he didn't know what kind of treatment she was seeking.
"Mrs. King was very health conscious, even before she got ill. I'm not surprised that she would explore every possible way of seeking treatment," Jakes said.

King died at 1 a.m. Tuesday, said Lorena Blanco, a spokeswoman for the U.S. consulate in Tijuana.
U.S. Embassy officials will work with the King family to ensure that their interaction with Mexican authorities is as smooth as possible - something they do whenever a U.S. citizen dies abroad, said Julia Tully, a spokeswoman at the U.S. Embassy in Mexico City.

King's daughters Bernice and Yolanda were at the hospital, where Mexican authorities told the family there is a legal requirement that King's body be embalmed before it is brought back to the United States, according to King's sister, Edythe Scott Bagley of Cheyney, Penn.
She said the family is complying and that it expects the body to be released later Tuesday.
"I do know that the body is going to be embalmed and the body and the children will be coming in tonight," said Bagley, who spoke with Yolanda King at the hospital.

Bagley also said that Mexican authorities were being cooperative with the family.
Mexican officials were not immediately available to comment.
Located 16 miles south of San Diego in Rosarito Beach, Mexico, the Santa Monica Health Institute says on its Web site that it uses an eclectic approach to diseases that are often believed to be incurable.

"The major patient clientele is comprised of cancer patients who have been told that there is no more hope, all traditional therapies having failed," it says.
The clinic says it also treats cardiovascular disease, diabetes, hepatitis C, arthritis, multiple sclerosis and other auto-immune diseases.

Employees answering the phone at the clinic's San Diego corporate offices refused to give out any information regarding patients.

Sacred Heart Offers New Laser Treatment for Narrowed Arteries

by Mike Burke
PENSACOLA, Fla. -- A new laser procedure offered at Sacred Heart Hospital may prevent many people from having to undergo lower limb amputations. Sacred Heart is one of the first health systems in the country to begin using a new laser procedure called CLiRpath® (Cool Laser Revascularization for Peripheral Artery Therapy).

Peripheral vascular disease refers to a narrowing of vessels that carry blood to the legs, arms, stomach or kidneys. Common symptoms include leg pain during activity, weakness or fatigue in the legs, cramping or discomfort. One of the most advanced forms of peripheral vascular disease results in the obstruction of blood flow in the legs, which leads to rest pain, the development of foot ulcers and the onset of limb loss, which often results in amputation. The new laser produces an intense light beam, and short bursts of ultraviolet energy help clear the blockage. With restored blood flow, there may be a greater chance that wounds can heal, limbs can be saved, and that patient’s psychological and physical well-being can be improved.

“Technology continues to evolve, allowing us to treat more extensive vascular disease with minimally invasive techniques,” explains Dr. Christopher Bosarge, interventional radiologist. “This new technology offers patients with advanced peripheral vascular disease the best chance at avoiding the devastating complications of amputation.”The new laser treatment provides hope to the more than 100,000 Americans each year that have a toe, foot or leg amputated due to peripheral vascular disease.

“My ongoing collaboration with the interventional radiologists at Sacred Heart allows us to offer each patient individualized, comprehensive care for vascular disease,” expressed Dr. Stuart Harlin, vascular surgeon. “Adding the CLIRpath Laser system is another vital tool in our collection to successfully treat our patients with advanced peripheral vascular disease.”Patients at greatest risk for developing PVD are over the age of 50, smoke, have high blood pressure, do not exercise or have a family history of vascular diseases.For more information, please call (850) 479-1805.

High Mobile Termination Rates Discourage Usage - report

(www.cellular-news.com).- A new report from Telecommunications Management Group notes that while mobile telephone subscribers surpassed fixed line subscribers globally in 2002, mobile usage significantly lags fixed line usage. The main reason is the high price of mobile calls, which are often caused by high mobile termination rates (MTRs, the cost per minute of terminating a call on a mobile network).

There is compelling evidence that mobile users in countries with low termination rates or that charge the receiving party for the call spend more time talking on their phones. For example, users in the United States, where the receiving party pays for calls, speak on their mobile phones almost 600 minutes a month, whereas users in the European Union, where the calling party is charged for the call, use their mobiles an average of 142 minutes monthly.

The report finds that the average MTR in the world was US$0.142 at the beginning of 2005. MTRs among countries that have announced phased reductions are forecast to fall below US$0.109 per minute by 2007, a decline of 19% a year. There is significant variation in MTRs around the world, with Asian rates the lowest at US$0.048 per minute.

The mysterious guttural pouch

While the function of the guttural pouch in athletic performance is unclear, disease of the area can be deadly

(www.thoroughbredtimes.com).- A HORSE'S guttural pouch is the Bermuda Triangle of horse anatomy. Though the area can be well defined and located, it remains somewhat a mystery as to its purpose. Diseases that occur in this region can be quite severe, and, like the Bermuda Triangle, small problems can have deadly consequences.
Guttural pouch diseases do not occur frequently. They represented less than 0.5% of all cases presented to the Western College of Veterinary Medicine in California over a two-year period. But the potential adverse effects of these conditions on the individual horse warrant attention and discussion.

What is a guttural pouch?

A guttural pouch is an air-filled out-pouching of the auditory or Eustachian tube. While all mammals have auditory tubes, not all have these pouches. Horses, mules, and donkeys have the largest, with one pouch lying on each side of the back of the throat.

Eustachian tubes extend from the inner surface of each eardrum to the sides of the pharynx. The pharynx is the large opening in the back of the mouth/throat where the nasal passages and the oral cavity join before separating into the trachea (airway) and the esophagus (feeding tube). Eustachian tubes connect to this large pharyngeal cavity as slit-like openings on either side of the back of the throat.

Auditory tubes serve an important function by regulating pressure on the eardrums. (Some children have had surgery to implant drainage tubes in the Eustachian tubes to reduce earaches.) The outer ear of all animals is exposed to atmospheric pressure while the inner ear and the ends of the auditory tubes are exposed to the pressure within the throat, which can be very different.

As a horse or human ascends a high mountain, the atmospheric pressure becomes lower. If the pressure is severe enough, the eardrum begins to bulge outward, and, if not for the auditory tubes, it probably would rupture. The auditory tubes, however, allow the body to equalize this pressure.

Each time an individual swallows, the pharyngeal or lower end of the tube opens. If the outer ear pressure is higher, some air is taken into the tube until the pressure on both sides of the eardrum is equalized. The reverse occurs if the outside pressure is less than the inner pressure.

Because the horse spent much of its evolutionary development on flat grassland, pressure regulation does not appear to be a factor in explaining the extreme size of the equine guttural pouch. More recent research points to its ability to significantly cool the horse's brain by moving air in and out of the guttural pouch as probably its key function.

The exercising horse generates a tremendous amount of heat because of the massive amount of muscular work required for high-speed motion. This heat must be removed from the body or internal temperatures will rise to debilitating levels. Many large arteries and veins that supply the head and brain are closely associated with the inner lining of the guttural pouches.

Researchers now believe that heat is removed from the exercising horse's brain via transfer from the blood to the air in the guttural pouch and then out through the pharynx. This mechanism also provides a clue as to why diseases occur in this anatomical area and why those diseases can be deadly.

Potential for disaster

With each swallow, air enters or leaves the guttural pouch of the horse. This means that any bacteria, fungi, or other infectious agents inhaled or ingested by the horse have ready access to both pouches. These potentially disease-causing particles can enter the pouches and usually become trapped in the mucus that lines these structures.

Most of the time, the horse's immune system successfully destroys these agents, but bacteria or fungi occasionally survive and continue to grow by invading the lining of the pouches.

The guttural pouch is a two-chambered space separated by the stylohyoid bone, and it can hold roughly 20 ounces of fluid or air. The medial or innermost chamber has several important blood vessels and nerves located on its surface. These nerves are responsible for various crucial body functions, such as breathing, swallowing, and chewing.

The lateral or outermost chamber is associated with more nerves and contains the internal carotid artery and the maxillary-facial vein. Proximity of the guttural pouches and the nerves, arteries, and veins associated with them also exposes these critical structures to infection and damage. The design of the guttural pouch is a beneficial marvel for the horse, but it also is a potential disaster waiting to happen.

Tympany

There are three main diseases of the guttural pouch. The first is guttural pouch tympany.
Horses with this problem are born with a defect that causes the pharyngeal opening of the Eustachian tube to act like a one-way valve. Air can get in, but it cannot get out. This condition usually occurs in only one pouch, but it can affect both.

Because it is a problem present from birth, most cases of tympany are noted within the first few days of a foal's life. Several recent studies have looked at the genetic component of guttural pouch tympany, and links with the disease have been made to some Arabian and Hanoverian bloodlines.

Horses with tympany show massive swelling of the neck and throatlatch. If this swollen area is tapped with a finger, it resonates like a drum, which gives the condition its name. Affected horses might exhibit mild discomfort or be unable to breathe and swallow correctly if the swelling is severe enough.

Diagnosis is made based on the observed swelling and the foal's age, then the condition usually is confirmed by radiographs and endoscopic examination. Surgical correction is the treatment of choice, and one-sided tympany usually is easily corrected with a favorable prognosis. Those rare foals with both pouches affected require a much more complicated surgery and have a less favorable outcome, though recent advances employing laser surgery could soon improve their chances.

Pus-filled pouches
Guttural pouch empyema, or the presence of pus in the pouches caused by bacterial growth, is more common than tympany. Empyema usually occurs following an infection of the pharynx. Often significant infection can be present before external swelling of the pouch is noted.

The most common organism involved is Streptococcus equi, the causative agent of strangles. Horses with strangles often have abscesses in the pharynx that rupture and drain, which allows Streptococcus bacteria to gain entry into the guttural pouch. This bacterial strain can live in the guttural pouch for weeks to months causing a large amount of mucus that contains white blood cells from the immune system, bacteria, and necrotic tissue from the guttural pouch. A thick, pasty material develops that is not easily drained away.

The top part of the pouch might contain more fluid, but the bottom of the pouch holds a thicker material of almost cottage-cheese consistency with occasional solid masses of debris called chondroids.
An affected horse will show a persistent, creamy discharge, usually from one nostril. When the horse lowers its head to graze, the discharge usually increases as gravity allows more pus to exit the pouch into the pharynx and flow out the nasal passage.

Initially, these horses are rarely sick, but chronic infection will result in progressive weight loss, debilitation, and potential damage to the nerves and vessels within the pouch.

If the nerves become involved, horses can exhibit difficulty eating and swallowing. They also can have difficulty breathing. Research has shown that one potential cause of laryngeal paralysis, or roaring, is infection of the guttural pouch. Dorsal displacement of the soft palate, which also affects breathing, can be a complication. If the facial nerves are affected, some horses also might develop a drooped lip or ear.

Some cases of empyema resolve themselves without treatment as the pus eventually drains from the pouch. The majority of horses, however, will require aggressive flushing of the pouch and antibiotic therapy. Specialized catheters are placed in the affected pouch, and large volumes of fluids are repeatedly flushed in and out with significant pressure.

If the condition is chronic and severe enough, surgery sometimes is needed to drain the pouch. This is especially true if large chondroids have formed. Though the surgical approach is technically difficult, horses that receive treatment before damage occurs to nerves and blood vessels show good response and might recover fully.

Danger to carotid artery

Guttural pouch mycosis is the most serious of the three pouch diseases and is caused by the presence of fungi in the pouch. Aspergillus, Candida, Penicillium, and Mucor are the fungi most commonly found; they easily are encountered in hay, forage, and other parts of the horse's natural environment.

Fungal infections in the guttural pouch usually begin over one of the main arteries that traverse the pouch walls. Interestingly, research has shown that a defect in the artery wall is necessary for the fungal infection to start and that restricting blood flow through the artery might cure the condition without other treatment. If the mycosis is not resolved, however, the fungal infection slowly will erode the walls of the blood vessel, and the horse will begin to bleed.

The first sign of guttural pouch mycosis might be intermittent bleeding from one nostril, or epistaxis. If this mild bleeding is allowed to continue untreated, the blood vessel eventually will rupture, and the horse will bleed to death.

Fungal damage also can occur to the nerves within the walls of the pouches. Horses with this condition, even if they are treated and do not succumb to bleeding, could remain unable to eat and swallow. They often lose tremendous amounts of weight and eventually die.

Treatment involves a complicated surgery to ligate or tie off the blood vessels traveling through the affected pouch. Balloon catheters and surgical lasers now are being used in these procedures, but the prognosis for these horses remains guarded.

Antifungal medication is administered along with surgery for optimal chances of return to function in these cases. If the diagnosis can be made early, there is a better chance that surgery can be done and that no permanent damage will occur to crucial blood vessels and nerves.

Pay close attention

Few other areas in the horse's body are as important to its ability to function as an athlete but can lead to its destruction. Add the fact that the guttural pouches cannot be seen and are difficult to comprehend even with a description.

Yet, knowing about their existence, their function, and the signs of possible disease might allow you seek early treatment for your horse. Problems in this area do not happen often, but when they do, quick response could save a horse's life.

Optimata Granted Patent for Use of Virtual Patient Technology in Cancer

Optimata Ltd. announced today that the US Patent and Trademark Office has granted patent approval for the use of Optimata's Virtual Patient biosimulation technology in the optimization of drug treatments for cancer patients. This is the first approval of a series of patent applications filed by Optimata for the company's platform technology, which employs mathematical modeling to optimize the use of drugs in the development of new drugs and in the treatment of diseases.

The approved patent is titled "System and Methods for Optimized Drug Delivery and Progression of Diseased and Normal Cells" and is registered as patent number 6,871,171.
"The awarding of this patent, which covers the company's core Virtual Patient technology, reinforces Optimata's position as the leading developer of innovative biosimulation solutions aimed at dramatically accelerating drug development. We have already successfully used this technology in our collaborations with pharmaceutical and biotech companies," said Guy Malchi, Optimata's president.

Optimata's technology is based on a computer-generated method of accurately predicting how individual patients or patient populations will respond to a compound. The technology combines computer models of human physiology, specific diseases and the therapeutic impact of a compound. The technology forecasts the results of putative preclinical and clinical experiments at an unprecedented scale, allowing an unlimited number of "virtual trials" to be carried out on a wide range of dosages, treatment schedules and patient population characteristics.
In this way it is possible to overcome the time and cost limitations of the trial-and-error methods currently used in drug development and to establish the optimal therapy protocol in a significantly quicker way.
Optimata is currently completing a clinical trial to predict breast cancer therapy outcomes for cancer drugs such as Adriamycin, Docetaxel, Paclitaxel, Vinorelbine and Tamoxifen at Nottingham City Hospital in the UK and at

the Soroka Medical Center in Israel.

FDA Approves New Treatment for Gastrointestinal and Kidney Cancer

The Food and Drug Administration (FDA) today announced approval of Sutent (sunitinib), a new targeted anti-cancer treatment for patients with gastrointestinal stromal tumors (GIST), a rare stomach cancer, and advanced kidney cancer. Today's action marks the first time the agency has approved a new oncology product for two indications simultaneously.

Sutent, which received a priority review and was approved in less than six months, is a tyrosine kinase inhibitor working through multiple targets to deprive the tumor cells of the blood and nutrients needed to grow.
"Today's approval is a major step forward in making breakthrough treatments available for patients with rare and difficult to treat forms of cancer" said Steven Galson, MD, Director of FDA's Center for Drug Evaluation and Research. "New targeted therapies such as Sutent are helping FDA expand options for patients for whom there are limited alternatives."

According to the American Cancer Society, about 32,000 new cases of advanced kidney cancer and 5,000 cases of GIST are diagnosed each year.
Sutent was approved for the treatment of patients with gastrointestinal stromal tumors (GIST) whose disease has progressed or who are unable to tolerate treatment with Gleevec, the current treatment for GIST patients. While studying the treatment in patients, researchers conducted an early (interim) analysis of data that showed Sutent delayed the time it takes for tumors or new lesions to grow in patients with this rare type of stomach cancer. Specifically, the median time-to-tumor progression (TTP) for patients treated with Sutent was 27 weeks compared to 6 weeks for patients who were not treated.

FDA also granted accelerated approval for Sutent in the treatment of patients with advanced renal cell carcinoma (RCC). In contrast to the approval for GIST, which was based on the drug's ability to delay the growth of the tumors, this approval was based on Sutent's ability to reduce the size of the tumors in patients. An overall response rate ranging from 26-37 percent was found in patients with metastatic kidney cancer whose tumors had progressed following cytokine-based therapy.

"Today's approval of this drug for these indications provides compelling evidence that the use of alternative data endpoints allows us to see the benefits of novel therapies earlier in patients," said Richard Pazdur, MD, Director of FDA's Office of Oncology Drug Products.
The FDA has a long-standing commitment of providing patients suffering from serious and life-threatening diseases access to safe and effective treatments, in some cases prior to FDA approval. In the GIST clinical trial, significant clinical benefit was determined through an early interim analysis of data, thereby allowing researchers to convert all patients in the trial to treatment. For the RCC indication, the FDA used its accelerated approval process, a regulatory mechanism that expedites drug approvals for serious and life-threatening diseases.
FDA worked with the product sponsor to offer an expanded access program prior to approval, making the product available to patients not enrolled in a clinical trial. Currently, more than 1700 patients are being treated with Sutent through the expanded access program.

"Expanded access programs have proven to be an effective way to get treatment to patients who need it most, especially in cancer," said Ellen Stovall, President of the National Coalition of Cancer Survivorship. "There needs to be a greater awareness among patients and doctors about both the option to participate in clinical research as well as in these expanded access programs in order to make promising new therapies available to as many patients as possible."

The most commonly reported Sutent-related side effects included diarrhea, skin discoloration, mouth irritation, weakness, and altered taste. Patients treated with Sutent also experienced, fatigue, high blood pressure, bleeding, swelling, and taste disturbance. Hypothyroidism was also observed.
Sutent will be distributed by Pfizer Labs, Division of Pfizer, Inc. in New York, NY.

ALR Technologies Medication Compliance Reminder Product Selected for Use in Kenya Research Study for AIDS Patients

WINSTON-SALEM, NC -- (MARKET WIRE) -- 01/18/2006 -- ALR Technologies Inc. (OTC BB: ALRT), headquartered in Winston-Salem, NC, announces today that one of their medication compliance reminder products, the ALRT PC200, has been selected for use with an AIDS study to be conducted in Kenya.
The study, conducted by the University of Washington, Seattle, WA and the University of Nairobi, Kenya, is designed to determine whether certain interventions can improve compliance to antiretroviral medications among patients living with AIDS in Kenya. The study is funded by the National Institutes of Health (NIH) and is being performed at the Hope Center for Infectious Diseases at the Coptic Hospital in Nairobi, Kenya.
According to Dr. Michael Chung of the University of Washington, compliance to antiretroviral medications is essential for the proper treatment of AIDS in Africa; "Delivering antiretroviral medications to those in need is of paramount concern, yet once the drugs are made available proper compliance in the administration of the medications is essential. The ALR devices used in this study will help us determine possible methods for improving compliance."

Based on data available from the World Health Organization (WHO), there are approximately 39.4 million people internationally living with HIV/AIDS and there were 4.9 million new infections in 2004. The WHO information further reported there are about 25.4 million people in Sub-Saharan Africa living with HIV, 7.1 million in South and South-East Asia, 1.1 million in East Asia, 1.7 million in Latin America, 1.4 million in Eastern Europe and Central Asia, 1 million in North America and 610,000 in Western and Central Europe.
ALR Technologies reports that the ALRT PC200 product selected for the research study is now being marketed in North America and many HIV/AIDS clinics are now using it. The product was designed for ease of use and it can be quickly and easily set by a technician and then given to the patient to take home.

About EECP(R) Therapy - External Counterpulsation
EECP external counterpulsation therapy is typically given in 35 one-hour sessions over seven weeks. Patients recline on a contoured treatment table and their calves, lower thighs and upper thighs are wrapped in a pneumatic cuff set. The system, which is synchronized to the individual patient's cardiac cycle, inflates the cuffs with air to create external pressure when the heart is resting and deflates the cuffs just before the next heartbeat. The system's action, which pulses counter to the heart's beating, increases blood flow to the heart muscle and other organs and decreases the heart's workload, creating a greater oxygen supply for the heart muscle while lowering its need for oxygen.
About Vasomedical
Vasomedical, Inc. is primarily engaged in designing, manufacturing, marketing and supporting EECP external counterpulsation systems based on the Company's unique proprietary technology. EECP therapy is a noninvasive, outpatient therapy for the treatment of diseases of the cardiovascular system currently indicated for use in cases of stable or unstable angina, congestive heart failure, acute myocardial infarction and cardiogenic shock. The therapy serves to increase circulation in areas of the heart with less than adequate blood supply and may restore systemic vascular function. The Company provides hospitals, clinics and private practices with EECP equipment, treatment guidance and a staff training and equipment maintenance program designed to provide optimal patient outcomes. Additional information is available on the Company's website at www.vasomedical.com.

China calls for global early warning system against epidemics

BEIJING, Jan. 18 (Xinhuanet) -- Chinese Premier Wen Jiabao on Wednesday suggested that the international community set up a monitoring and early warning system against epidemic diseases as soon as possible and help all countries in their capacity building in this regard.

The international community should make joint efforts to intensify scientific research in the area of epidemiology and medicine development for bird flu prevention and control, Wen told the ongoing international pledging conference on avian and human pandemic influenza.

"China is ready to provide personnel training to member states of the Association of Southeast Asian Nations and the neighboring countries, and conduct technical exchange with concerned countries on epidemiological survey, early warning and monitoring, laboratory testing, and clinical diagnosis and treatment," the premier said.
"We are also willing to cooperate with concerned countries and international organizations in the development of vaccine and medicine for effective prevention and control of bird flu," Wen added.
Wen also called on the international community to establish a global cooperation mechanism for the prevention and control of avian influenza.

The international community should make full use of the advantages of various regional and sub-regional mechanisms, and draw out specific measures for bird flu prevention and control, he said.
In order to promote the global cooperation, Wen suggested the international community set up a mechanism for joint prevention and control.
China is a responsible country and is ready to continue cooperating with the international community in this regard, said the premier.
"We are willing to share our experience with relevant countries and help them work out measures for the prevention and control of avian influenza." Wen said.
Wen Jiabao expressed the belief that the global efforts will finally lead to victory in the fight against bird flu.
The international community attaches great importance to bird flu prevention and control, and related international cooperation,which is in full swing, has resulted in remarkable achievements, said the premier.
However, he said, the epidemic situation is still grave and bird flu prevention and control remains a tough job.
"I believe that through the joint efforts of the international community and all delegates here, we are sure to bring bird flu under control and make new contribution to the civilization and progress of mankind," said Wen.
Nearly 700 delegates representing more than 100 countries and regions and 20 international organizations attended the conference in a bid to pool financial resources to curb the spread of bird flu. Enditem

Autoimmune system in humans viewed (November 29, 2005) -- University of California-San Francisco scientists say they've devised a way to view how the human body averts autoimmunity. Jeffrey Bluestone, ... > full story
In a study published online in Nature, researchers from the university's medical school found that the protein cryopyrin responds to invading bacteria by triggering the activation of a powerful inflammatory molecule called IL-1beta, which signals the immune system to attack pathogens and induces fever to protect the body against infection.

Found in the fluid inside cells, cryopyrin is a member of the NOD-LRR family of proteins, which protect cells against microbial infection. Defective cryopyrin is associated with increased susceptibility to infection.
Small mutations in CIAS1 --the human gene for cryopyrin-- are known to cause three rare autoinflammatory diseases: familial cold autoinflammatory syndrome, Muckle-Wells syndrome and neonatal-onset multiple-system inflammatory disease.

The scientists found that activated cryopyrin triggers an enzyme called caspase-1, which splits the immature form of IL-1beta to produce the active form of the molecule. Once IL-1beta is activated, it can be secreted out of the cell where it binds to the IL-1beta receptor on other cells to trigger an immune response.

Kalam stresses on stem cell research for chronic kidney diseases

President A P J Abdul Kalam today urged the scientists to work on ways to activate stem cells to treat those suffering from renal failure.

''We have to work persistently to find a long-term solution to CAD through stem cell research,'' he underlined, while launching the Kidney Care Project of the CARE foundation here.

With increasing incidence of diabetes and hypertension, it was imperative to concentrate on creating public awareness on the causes of the disease and symptoms as treatment to Chronic Kidney Disease (CKD) was unaffordable to most people, he pointed out. Stressing the need for more mobile clinics for the benefit of people living in the rural areas, Dr Kalam said 15 people out of 1,000 have kidney disease and one lakh people go into endstage kidney diseases every year in the country requiring either dialysis or kidney transplant.

He said more than 60,000 patients fail to continue with dialysis due to financial constraints and lose their lives within a year in a slow and very painful manner.

Stating that hardly 5,000 kidney transplants were being carried out in the country, he stressed the need for building social acceptance of cadaver kidney transplant. As many as 80,000 accidental deaths occur every year, he pointed out.

Commending the CARE hospital for launching the pioneering Little Heart Project earlier for treating children with heart diseases, he said other hospitals in the country had started emulating the CARE foundation to provide financial relief to children of patients who could not afford treatment.

Dr Kalam expressed confidence that the new initiative of the CARE foundation would definitely help those suffering from CKD feel that they were not alone and make the treatment affordable to them.

Describing poverty as a social issue, he wanted everyone financially comfortable to liberally donate for the foundation.

Later, the President interacted with a team of cardiologists from Tanzania, undergoing training at the hospital and also signed his autograph on the portrait of Florence Nightingale, while talking to nurses from Manipur.
He also honoured Dr Ranganath Rao and Gopalakrishna, who performed the first kidney transplant in the city at the Osmania General Hospital and declared open a CARE Learning Centre.

Thanks to Dr Kalam's gesture of donating Rs one lakh to the Little Heart Foundation, people from different walks of life had contributed Rs 2.75 crore helping it operate 500 children so far, CARE Hospital Chairman and Managing Director B Soma Raju said.

Mr Soma Raju wanted Mr Justice B P Jeevan Reddy, who was supervising the functioning of the Little Heart Project to monitor the functioning of the Kidney Care Project too.
