Complex matters of the heart

Complex matters of the heart

A complex for improved imaging of the heart has been developed, which could save thousands of lives.

Isabel Santos and co-workers at the Institute of Nuclear Technology, Sacavém, Portugal, have made a technetium based complex, using a simple one step reaction, that can be used to image the heart more accurately than the state-of-the-art contrast agent.

The current 99mTc-sestamibi complex, used for imaging, is slow to clear the bloodstream and liver which makes it difficult to distinguish the heart from other non-targeted organs and surrounding tissues.
Santos explains 'due to the high incidence of cardiovascular diseases there is a need for good performing radiopharmaceuticals for rapid and accurate detection' before a heart attack occurs.

Santos's 99mTc tricarbonyl complex, with ether functionalisation, clears the blood and liver three times faster then the state-of-the-art in the clinical trials performed on rats, which allows for a much better contrast image between the heart and the liver, allowing for faster and more accurate diagnoses of coronary artery disease.

Francesco Tisato, an expert in the use of technetium in medical and biological chemistry at the Institute of Inorganic Chemistry and Surfaces, Padova, Italy, says that the significant and persistent heart uptake with favourable clearance of the liver and lungs may help to improve heart imaging.

Santos goes on to say that the next stage of development is to test the complex in clinic trials to confirm its performance in humans.

Bad mouth odour is the worse

Bad mouth odour is the worse

Bad mouth odour is the worse one could ask for or dream of. It spoils the best one can give or maybe even the first impression. Proper dental health care is sure to ensure healthy teeth and fresh breath. When it comes to ones teeth they are meant to last out for lifetime, and good dental care can make them last out for long.

Since there are natural teeth in the mouth, tooth decay can occur since there could be remaining bacteria, which sticks to the teeth and causes dental plaque. Plaque can only be removed with careful brushing every single day. Along with brushing flossing also helps remove plaque and leftover food.

For good dental health, one should ensure good brushing with a good toothbrush as worn out toothbrushes do not help in cleaning teeth and can also cause injury. Your toothbrush should be replaced every three months for better gums and teeth.

When it comes to a smile it could win over anyone at anytime or age. Fluoride is very essential for both adults and children. Which could be found in drinking water and some food items. A balanced nutritious diet can go a along way for good dental health, including raw vegetables, cheese and fruit.

A good dentist goes a long way in ensuring good dental health with regular check ups even in the case of false teeth or dentures and even real teeth. Good oral health can also be had with good toothpaste, never compromise on good toothpaste.

Incase of dentures they should be kept clean without the presence of leftover food particles, which in turn could cause gum irritation and bad breath. The entire surface of the dentures should be brushed very well. When one usually crosses 35 years and above one may experience tooth loss because of a gum disease known as periodontal disease, which is caused due to infections of the gum and bone that keep and hold the teeth in its place.

Natural permanent teeth could be had only once in a lifetime, and you should take good care of your teeth and be even more confident. As you look in the mirror to see you teeth you will automatically smile back, but this will only happen when you ensure good dental care and health. Refrain from activities such as too much coffee and smoking.

By keeping your mouth healthy you are ensuring a healthy body. Take proper care of your teeth and have white attractive teeth and a rewarding smile all life long.

Good dental hygiene helps keep children happier

Good dental hygiene helps keep children happier

What you should know:-

Children with healthy mouths are usually happier and healthier overall.

Good oral health habits can decrease the risk of gum infections that can affect overall health. Pain and the risk of serious problems can be reduced when infections are treated quickly. Children have suffered high fevers and even died from severe tooth and gum infections that spread to the brain.

The structure of a child's mouth can affect the ability to eat, breathe, swallow and speak properly. Healthy baby teeth are important to hold places for permanent adult teeth. Pediatricians can check the shape of a baby's mouth and recommend ways to correct problems. Severe problems, such as a cleft lip or palate may require surgery.

Care of the mouth begins at birth. Parents and health professionals can look for oral problems that can affect the development of a child. Parents can start a routine of good oral hygiene, so gums and baby teeth stay healthy.

Regular dental check ups can detect and treat oral health problems before they become severe.

Many federal, state, school and private programs pay for oral health care for children in the Mid-South.

Federally funded programs in Tennessee have included Head Start, Women Infants and Children's program (WIC), the Centers for Disease Control and Prevention for the Water Fluoridation Assistance Program, TennCare and Medicaid. TennCare has a contract with Doral Dental to provide oral health and preventive care to children of low-income families.

The State Children's Health Insurance Program (SCHIP) has helped many children in the South get dental care.

The Tennessee, Mississippi and Arkansas Departments of Health have programs to help public school students get preventive dental care. Children with good oral health miss less school. Tooth pain is a big reason for absence.

Mid-South children have benefited from programs in which nurses apply a fluoride varnish to their teeth. Many students have also benefited from dental sealant programs. Sealants create a barrier between teeth and the sugars and bacteria that can cause tooth decay. Sealants in the grooves of molar teeth are effective in preventing cavities.

The combined use of sealants and fluoridation has greatly reduced the rate of tooth decay in children.

There are many wonderful oral health programs. Yet, many children do not receive regular dental care. Some parents put off getting dental care for children, especially when the economy is poor. Many kids in the Mid-South lack dental clinics close to home. Poor children suffer from oral health problems more than wealthier children. Some children lack care because some dental professionals refuse to accept Medicaid, TennCare or certain insurance plans.

Many employers offer health insurance to employees and their families. However, many do not offer dental care.

Children without dental insurance are far less likely to get dental care than those who do have coverage.

What you should do:-

Make sure children get professional care for their teeth and gums every six months.

A child's first dental visit should be by 18 to 24 months of age. Clean teeth as soon as the first baby tooth shows up.

Stress the importance of good nutrition and oral hygiene to children of all ages.

Teach older children about proper brushing with fluoride toothpaste at least twice daily. Mention flossing, too.

Teach children about the damage that sugar, bacteria, tobacco and alcohol can do to their gums and teeth.

Give kids low-sugar snacks like celery and carrots.

Parents of babies should prevent problems that can develop before a child gets permanent teeth. Thumb sucking can distort a child's teeth. Some parents cause cavities when they put babies to bed with bottles of milk, soda or fruit juice. Many parents protect their babies by changing over to cups for drinking by the first birthday.

Don't ignore a child's tooth or gum pain or bleeding gums. Also keep an eye out for infections, such as cold sores.

Protect a child's mouth. Children who play sports may need mouth guards. Prevent unintentional injuries to the mouth by teaching good habits and safety. Tell children not to chew on pencils, spoons or other hard items.

Instant insight: Smart dental implants

Instant insight: Smart dental implants

Henning Schliephake from the George-Augusta University, Göttingen, Germany, discusses the state-of-the-art dental implants making their way to a dentist's surgery near you

Dental implants are screws or cylinders, commonly made of titanium, which are inserted into the jaw bone in a surgical procedure. They act as artificial roots and can provide anchorage to crowns and bridges after the original root has been lost. Close contact between the adjacent bone and the implant surface is important for the artificial roots to remain fixed for the long-term. This bone-to-implant contact is accomplished by the growth of new bone on the titanium surface. The adsorption of biomolecules and blood components onto the titanium from the body fluids surrounding the implant is a crucial step in this process. This allows bone cells and their precursors to approach the surface and start growing bone tissue. Bone healing may be compromised by previous infection, radiotherapy or osteoporosis, and this can jeopardise the process and lead to implant failure.

In recent years, material scientists and clinicians have developed a number of approaches to improving the regenerative capacity of adjacent bone. One strategy is to create surface conditions that encourage quicker and more intense adsorption of biomolecules onto the implant surface, by altering the implants surface morphology and surface chemistry. Increasing the surface roughness using acid etching and sandblasting combined with integration of fluoride ions or calcium phosphate nanocrystals considerably increases the speed and strength of the bone-implant contact.

An alternative way of enhancing bone formation on the implant surface is using biological signals to attract bone cells to the surface and increase the speed they grow. Some of these signals are based on a short sequence of amino acids - the so called RGD motifs - that bind to specific receptors on the cell surface initiating cell migration and/or increasing cellular activity. The signals are held in place by various types of linker molecules that are anchored to the titanium surface.

Another way to accelerate bone growth is using signalling molecules or growth factors to accelerate cellular specialisation. As bone forming cells originate from so called precursor cells, using osteogenic signalling molecules such as bone morphogenic proteins on the implant surface could considerably increase the number of bone forming cells and therefore the amount and strength of the bone grown.

In native bone, many of these osteogenic signalling molecules are encased in the bone matrix, a highly structured assembly of minerals and proteins, which provides three-dimensional stability to the bone tissue. This reservoir of growth factors aids the healing process of bone, for example after a fracture. The most complex approaches among recent surface modifications of titanium implants have tapped into this source to produce matrix-engineered surfaces. Here bone matrix proteins such as collagen are arranged on the implant surface, together with molecules that bind growth factors in native bone, to provide a reservoir for osteogenic signals that are slowly released from the surface in a nature-like fashion after implant placement.

Many of these biological approaches have yet to work their way from the bench to the bedside. However, the huge potential of this research and improved biotechnological capabilities will eventually prove useful for the incorporation of many types of artificial materials into the human body - extending far beyond the integration of dental implants.

Turning the light off on tooth bleaching

Turning the light off on tooth bleaching

Norwegian scientists have demonstrated that light sources often used as part of the tooth bleaching process do not contribute to the effectiveness of the process and may pose possible health risks.

Tooth bleaching is becoming a popular way to remove stains on the teeth caused by smoking, red wine, tea and coffee, in an attempt to achieve a Hollywood smile. The process used by dentists to bleach teeth involves applying an oxidising agent to the teeth and in some cases a light source is then shone onto the teeth.

Ellen Bruzell from the Nordic Institute of Dental Materials, Haslum, and colleagues, measured the effectiveness of teeth bleaching using seven different commercially available products, with and without using light sources. The claim that light-assisted tooth bleaching is more efficient than ordinary bleaching has not been substantiated in the literature, explains Bruzell. She says that they found a 'lack of additional whitening effect when light is used compared to bleaching without light'.

The team also demonstrated that for the majority of the light sources tested, the amount of radiation a person is exposed to during the bleaching process poses a risk of damage to the skin and eyes if proper protection is not used. Thomas Attin, an expert in preventative and restorative dentistry from the University of Zurich, Switzerland, comments that this study is very interesting and says that 'the aspect that the light sources used for bleaching may cause some risks (not only to the teeth) is new.'

Bruzell also found an increase in exposed perichymata (grooves on the surface of the tooth enamel) on the bleached teeth compared to unbleached control teeth, showing that the tooth bleaching process removes part of the pellicle that covers the enamel's surface, making the teeth more vulnerable to mechanical stress.

Bruzell says she is now carrying out a study on the effectiveness of first time tooth bleaching. Future work may also include investigating the effects of optical radiation on oral tissue and looking into the adverse effects of repetitive tooth bleaching, she adds.

Take care of oral health

As we enter 2009, many of us have already adopted a resolution for the New Year. While beginning a diet, committing to an exercise routine or spending more time with family are great choices, placing a priority on your oral health should be near the top of anyone's list.

Medical research has found that infections or bacteria in the mouth are linked to overall health. Periodontal (gum) disease, an infection of the tissues that support the teeth, is closely associated with the development of strokes, heart disease, pre-term births and pneumonia.

Additionally, people with diabetes are more likely to have gum disease, which can make it more difficult for diabetics to control their blood sugar. Gum disease may also be a risk factor for diabetes, even in people who are otherwise healthy.

You can help minimize your risk by following good oral-hygiene steps and visiting your dentist twice a year for exams and cleanings. Oral cancer screens are part of routine dental exams, and new advanced technology can help detect oral cancer at its earliest stages.

There are several things we can do on a daily basis to get on the right road to excellent oral health. Brush your teeth at least twice a day and floss at least once daily. Limit your intake of sweets, especially sugared, carbonated beverages. Eat more fruits and vegetables. Drink more water. Individuals with dentures should brush and rinse their dentures daily and clean with denture cleanser.

Remember, it is important to visit your dental team for regular exams, screenings and cleanings. Denture wearers are checked to ensure dentures fit properly.

Taking care of your oral health will help your overall health throughout the New Year and beyond.

Town braced for new NHS dentist surgery

DENTISTS are expecting to be inundated with patients after a new NHS surgery was announced for a Suffolk town.

The new Bury St Edmunds practice is expected to open on Woolhall Street in April and is the first sign in the town of a package of investment tackling the county's NHS dentist shortage.

The announcement has been welcomed by patients and community leaders in an area where only 22% of practices are accepting new patients. And according to NHS Suffolk one-in-four 5-year-olds have decaying, missing or filled teeth.

The move comes after Suffolk health bosses conceded there was “significant unmet need” and “although there is a statutory duty to ensure that there is reasonable access to dentistry, it is not clear that this requirement is being met everywhere”.

The Bury practice set to be run as the White Cross practice and is part of a £1.8million overhaul to increase access for patients in response to the problem.

David Lockwood, chairman of Suffolk County Council's health scrutiny committee and St Edmundsbury Borough Council member, said: “This is great news for the west of the county. A new practice has already opened in Brandon and it has already begun making a difference.

“And the addition of investment orthodontic services is also going to be fantastic.”

The money, first announced last September, has also been earmarked for new practices in Sudbury, Hadleigh, Eye and Stowmarket, with further investment in Saxmundham, Woodbridge and Newmarket.

Among the recommendations to be implemented by the funding - of which £500,000 will be spent on orthodontics - people living in urban areas should be within five miles of a dentist and people living in rural areas should be no more than 12 miles away from a surgery.

A spokesman for NHS Suffolk said: “NHS Suffolk is spending £1.3million this year to improve access to dental services across the county, with a further £500,000 for orthodontic services.

“As part of this, we are now working closely with the owners to establish the new practice in Bury St Edmunds, and further details will be announced over the coming weeks.”

Effective new malaria drug to be approved by FDA

Washington (IANS): The US Food and Drug Administration (FDA) is likely to approve a new malaria drug with artemisinin, a wormwood derivative from China that has proven effective for the infection in Africa and Asia.

Although only about 1,500 reported cases of malaria are treated in US annually, the drug would also be made available to the military and to Americans planning to go abroad.

However, worldwide malaria is still one of the most serious infectious diseases, claiming two million lives and affecting two to three billion people every year.

Named Coartem, the drug is made by Swiss company Novartis. It combines artemether, an artemesinin derivative, with lumefantrine, a drug developed by Chinese scientists, which does not kill parasites as quickly but lingers in the blood a while longer.

By mopping up parasites that artemisinin misses, lumefantrine helps prevent resistance that would defeat the drug, as has occurred with other therapies like chloroquine.

University of Pennsylvania pharmacologist Doron Greenbaum, said although the exact mechanism by which artemisinin kills parasites is still open to considerable debate, the drug likely acts against one or more protein targets that may make it susceptible to resistance that has developed to most other drugs.

Drug resistance to artemisinin has already been shown to occur in the lab, and reports have already surfaced about potential resistance in malaria endemic regions like southeast Asia.

Thus the potential success of Coartem treatment for malaria should be greeted with cautious optimism knowing that resistance is likely to arise and that other new drugs will need to be developed quickly.

Greenbaum recently reported that small molecule defensin-mimetic compounds discovered by Radnor, Pennsylvania-based biopharmaceutical company PolyMedix, irreversibly kill P. falciparum while sparing human red blood cells.

Plasmodium species are responsible for the nearly 500 million cases of malaria worldwide and as many as two million deaths, most of them in children.

As with antimicrobial agents, first-line malaria agents are losing effectiveness due to development of resistance to drugs by the target organisms.

Greenbaum demonstrated that PolyMedix's compounds kill P. falciparum irreversibly, meaning the cells do not recover when the agent is depleted.

Irreversible killing distinguishes a "cidal", or true killing mechanism, from a "static" mechanism that holds the infectious agent at bay while the body's immune system fights off the infection, said a Pennsylvania release.

"If we treat for 10 hours and remove the compound, the parasites never recover," notes Greenbaum. Many antimicrobial and antifungal drugs are of the static variety.

'Alzheimer's drugs double death risk in elderly'

London (AP) :- Anti-psychotic drugs commonly used to treat Alzheimer's disease may double a patient's chance of dying within a few years, suggests a new study that adds to concerns already known about such medications.

"For the vast majority of Alzheimer's patients, taking these drugs is probably not a worthwhile risk," said Clive Ballard, the paper's lead author, of the Wolfson Centre for Age-Related Diseases at King's College London.

"Would I want to take a drug that slightly reduced my aggression but doubled my risk of dying? I'm not sure I would," Ballard said.

The research was published today in the medical journal, Lancet Neurology.

Alzheimer's disease is the most common cause of dementia and causes symptoms including aggression, delusions and hallucinations. Previous studies have shown anti-psychotic drugs, which can help control the aggression and hallucinations for a few months raise the risk of death in older patients with dementia. There are other side effects, including respiratory problems and stroke.

Ballard and colleagues followed 165 patients aged 67 to 100 years with moderate to severe Alzheimer's disease from 2001 to 2004 in Britain. Half continued taking their anti-psychotic drugs, which included Risperdal, Thorazine and Stelazine. The other half got placebos.

Of the 83 receiving drugs, 39 were dead after a year. Of the 82 taking fake pills, 27 were dead after a year. Most deaths in both groups were due to pneumonia.

After two years, 46 per cent of Alzheimer's patients taking the anti-psychotics were alive, versus 71 per cent of those not on the drugs. After three years, only 30 per cent of patients on the drugs were alive, versus 59 percent of those not taking drugs.

Scientists closer to finding cure for cancer afflicting kids

Sydney (IANS): Researchers have edged closer to finding a potential cure for the commonest tumour afflicting young children.

Michelle Haber AM, executive director, Children's Cancer Institute Australia (CCIA), said the findings were an exciting development towards an eventual cure for this childhood cancer.

Researchers have known that the presence of multiple copies of the cancer-associated gene, MYCN, in neuroblastoma tumours is a powerful predictor of death in this disease.

It has also been known that MYCN drives the expression of many other genes including one in particular called ODC1.

"Patients whose tumours carry multiple copies of the MYCN gene have a particularly poor prognosis and new therapies are urgently needed," said Haber.

"Our findings indicate that over expression of the ODC1 gene contributes to the aggressive biology of this tumour and poor clinical outcomes, said a CCIA release.

Using a lab model of neuroblastoma, researchers tested whether inhibiting ODC1 activity with difluoromethylornithine (DFMO), a drug known to suppress ODC1 function, would improve treatment of neuroblastoma, when used in combination with conventional chemotherapeutic drugs.

"We found that the combined drug treatment prolonged tumour-free survival compared with chemotherapeutic drugs alone, suggesting that targeting ODC1 for suppression is a potentially valuable therapeutic approach," said Haber.

Inflamed gums, heart disease linked

LONDON:- The next person who reminds you to floss might be your cardiologist instead of your dentist, for a new study has revealed a link between inflamed gums and heart disease.

Scientists have known for some time that a protein associated with inflammation called CRP is elevated in people who are at risk for heart disease. But exactly where is the inflammation coming from?

Well, researchers have found that infected gums may be one place. Indeed, proper dental hygiene should reduce the risk of atherosclerosis, stroke or heart disease independently of other measures, such as managing cholesterol.

"It has been long suspected that atherosclerosis is an inflammatory process, and that periodontal disease plays a role in atherosclerosis.

"Our study suggests that this is the case, and indicates that something as simple as taking good care of your teeth and gums can greatly reduce your risk of developing serious diseases," lead author Mario Clerici said.

In their study, the researchers from Britain and Italy examined the carotid arteries of 35 healthy people (median age 46) with mild to moderate periodontal disease before and after having their periodontal disease treated.

One year after treatment, they found that a reduction in oral bacteria, immune inflammation and the thickening of the blood vessels was associated with atherosclerosis.

Human bone marrow synthesised in lab Washington

Artificial bone marrow that can continuously make red and white blood cells has been synthesised in a lab for the first time. This could lead to simpler pharmaceutical drug testing, closer study of immune system defects and a continuous supply of blood for transfusions.

To determine whether the substance behaves like real bone marrow, the scientists implanted it in mice with immune deficiencies. They produced human immune cells and blood vessels grew through the substance.

Cancer-fighting chemotherapy drugs can strongly suppress bone marrow function, leaving the body more susceptible to infection.

The new artificial marrow could allow researchers to test how a new drug at certain potencies would affect bone marrow function, said Nicholas Kotov, co-author of the study and professor in University of Michigan departments of chemical and bio-medical engineering.

"This could assist in drug development and avoid severe side effects before human drug trials," he said.

The substance grows on a 3-D scaffold that mimics the tissues supporting bone marrow in the body, Kotov and Joan Nichols, professor at the University of Texas, collaborated on many aspects of the project.

"This is the first successful artificial bone marrow," Kotov said. "It has two of the essential functions of bone marrow. It can replicate blood stem cells and produce B cells. The latter are the key immune cells producing antibodies that are important to fighting many diseases."

Blood stem cells give rise to blood as well as several other types of cells. B cells, a type of white blood cell, battle colds, bacterial infections, and other foreign or abnormal cells including some cancers.

Bone marrow is a complicated organ to replicate, Kotov said. Vital to the success of this new development is the 3-D scaffold on which the artificial marrow grows. This lattice had to have a high number of precisely-sized pores to stimulate cellular interaction.

The scaffolds are made of a transparent polymer that nutrients can easily pass through. To create the scaffolds, scientists moulded the polymer with tiny spheres ordered like billiard balls. Then, they dissolved the spheres to leave the perfect geometry of pores in the scaffold.

The scaffolds were then seeded with bone marrow stromal cells and osteoblasts, another type of bone marrow cell, said a Michigan university release. The findings were published online in Biomaterials.

A Perfect Smile

Teeth are an important aspect of your personality. They play a major role in speech, digestionand enjoying food. It is essential to care for your teeth. Modern dentistry high-class equipment has made a visit to the dentist a less daunting and painless experience. Plain dentistry has evolved into a new role - cosmetic dentistry. The teeth can be so re-modeled and repaired that they bring happiness into the lives of people who were discontented with their looks. One need not lose self-esteem and self-confidence due to unattractive teeth. Cosmetic dentistry corrects the defects, gives you a dental facelift and augurs well for your confidence. It can change your appearance, making you feel better, look better and happier.

Advances in Cosmetic Dentistry

Cosmetic dentistry has made rapid advances in dental procedures. High-speed drills, anesthesia, sedation and comfortable surroundings relax the patients. The trauma of pain and anxiety associated with dental visit is greatly reduced. Natural colored filling material is available for front teeth, while back teeth can be plastic coated or filled with sealants to prevent tooth decay. Badly damaged teeth can be capped or crowned. Plastic braces have replaced the ugly metal braces. The invisible mouthpiece corrects the teeth without effecting your smile and confidence.

Services

Porcelain laminate veneers are specially made porcelain wafers. They are the same shade as your original teeth and can be placed over the chipped or disfigured teeth to make them look new. A gum-lift procedure can rid or lift the gum so that your teeth appear longer and whiter for an attractive smile.

Brilliant and dazzling white teeth are any persons dream. They can be achieved by tooth whitening

method. Use of high intensity light along with 35% hydrogen peroxide can whiten the teeth within an hour or two by an experienced orthodontist. At- home whitening is another self-help method. In this method special trays made to size are fitted in patients mouth, filled with 20% carbamine peroxide gel. They can be worn during sleep for a week to show whitening results.

Cosmetic Dentistry

Here are just a few of the ways a cosmetic dentist can improve the looks and appeal of normal teeth :-

Teeth Whitening :—Just over the past two to three years new and safe professional teeth whitening systems have been developed. The teeth are covered with gauze and the tooth bleaching (carbamide peroxide) solution carefully applied. After three or four half-hour sessions, you can really see the difference. There are also home tooth whitening products with step-by-step procedures that enhance tooth color over several weeks.

Dental Bonding :—It's a simple, single-visit cosmetic dentistry procedure that closes unsightly gapped teeth. We polish and prepare the teeth with a fine etching, then cover them with a composite overlay. There's usually no anesthetic needed, little or no drilling, and the teeth are protected as well as being cosmetically enhanced.

Dental Veneers :—Today we have exciting new biomaterials to straighten crooked teeth, as well as brighten and close gaps. We call them porcelain laminate veneers. They're microscopically thin ceramic shells that cover problem teeth—and leave you with something to smile about!
