Westies, as they are popularly known, are an attractive breed and got a media boost when featured in the Hamish Macbeth tv series, but it seems they may well be man’s best friend in more ways than one as they may hold the aswers to similar human diseases.

The Westie Foundation of America (WFA) has announced preliminary findings in two major studies involving the health of West Highland White Terriers and findings in these and studies of other dogs may hold answers for similar human conditions like Inflammatory Bowel Disease (IBD).

In one study, researchers are looking at the role of a mucosal gene driving inflammation Canine IBD, a chronic intestinal disorder that creates a bacterial-driven inflammation in the intestines. In the second, scientists are researching Legg-Calve Perthes Disease (LCPD), a debilitating developmental disease that causes pain, lameness and muscle atrophy of the dogs’ hip joints. Both are considering implications for humans since the diseases share commonalities in disease symptoms and pathology.

In IBD, genetic factors are thought to contribute to the cause of the disease in both dogs and humans and researchers are utilizing unique molecular biology tools to identify key genes which regulate intestinal inflammation, similar to human IBD.

Albert E. Jergens, DVM, PhD of Iowa State University is the study’s lead investigator and he explains: “It is our expectation to identify specific genes which serve as biomarkers for diagnosing canine IBD and for monitoring the effects of therapy. We have now identified a grouping of 17 ‘marker’ genes that may be more critically assessed in future studies. We have preliminary evidence that changes in the composition of the intestinal bacteria accompany the abnormal gene patterns…this situation is remarkably similar to the association between people and their intestinal populations causing human IBD (i.e., Crohn’s disease and ulcerative colitis).”

LCPD is an orthopedic disease that may require surgery to relieve the clinical signs and researchers are using technology to assess nearly 127,000 points in the dog genome. The goal of this project is to identify genes that contribute to the development of LCPD. Preliminary study findings show LCPD may be inherited in much the opposite way previous studies have shown. Earlier studies suggested LCPD is transmitted in an autosomal recessive pattern but the current data suggest it is inherited in either a dominant or complex fashion. The investigators currently have samples from 58 Westies, 23 of which have LCPD and more research is needed with the results of the candidate gene analysis to be published later this year.

Dogs are used in healthcare in other ways, as hospital visitors for instance where their presence is known to have a calming effect on patients and reduce their blood pressure but that they might help us get a cure for disease and hip disorders is certainly a step beyond that. If you have a Westie then perhaps an extra chew or toy as a thank you might be appropriate on behalf of his/her American relatives?

Is Your Smartphone Making Your Eyes Tired?

I sometimes feel like the last person on the planet who has a mobile phone that does just that – make phone calls. The rise of the new so-called ‘smartphones has been fast and furious and although we know of the dangers of over use of mobiles, it seems the new technology is throwing up another problem.

Several reports indicate that prolonged viewing of mobiles and other stereo 3D devices leads to visual discomfort, fatigue and even headaches. As more people are using smartphone, ipads, kindle readers and 3D game players this situation is going to get worse, not better. According to a new study reported in the Journal of Vision, the root cause may be the demand on our eyes to focus on the screen and simultaneously adjust to the distance of the content.

This is technically known as vergence-accommodation, and it this conflict and its effect on viewers of stereo 3D displays that the study has reported on.

Martin S. Banks, professor of optometry and vision science, University of California, Berkeley is the lead author of the study and comments: “When watching stereo 3D displays, the eyes must focus — that is, accommodate — to the distance of the screen because that’s where the light comes from. At the same time, the eyes must converge to the distance of the stereo content, which may be in front of or behind the screen.”

Through a series of experiments on 24 adults, the research team observed the interaction between the viewing distance and the direction of the conflict, examining whether placing the content in front of or behind the screen affects viewer discomfort. The results demonstrated that with devices like mobile phones and desktop displays that are viewed at a short distance, stereo content placed in front of the screen — appearing closer to the viewer and into the space of viewer’s room — was less comfortable than content placed behind the screen. Conversely, when viewing at a longer distance such as a movie theater screen, stereo content placed behind the screen — appearing as though the viewer is looking through a window scene behind the screen — was less comfortable.

At the moment we are talking discomfort, and the study was on adults, but presumably long term use and by youngsters will have a more serious impact. My local cinema now offers virtually every film as 2D (or what we used to call just film) and 3D and it is to the latter that the younger audience are drawn as when the new Harry Potter film was launched the 3D showing sold out faster. There has been an explosion of stereo 3D imagery in all areas, not just film and tv, but communication and medical technology as well.

“This is an area of research where basic science meets application and we hope that the science can proceed quickly enough to keep up with the increasingly widespread use of the technology,” added Banks.
The authors also propose guidelines be established for the range of disparities presented on such displays and the positioning of viewers relative to the display but in a world where we want colour, excitement and pzazz from our entertainment it may be that self – or parental – control might be the first step to avoid eyestrain and headaches.

Diet Drinks Can Increase Your Waistline and Put Weight On

During the summer we naturally consume more drinks to help with dehydration, and diet drinks are certainly popular for both refreshment and in the mistaken belief they help you lose weight. I say mistaken advisedly as a new study has shown that diet drinks actually cause weight gain and blood sugar spikes.

These diet drinks are made with artificial sweeteners like aspartame and a landmark new study out of Texas confirms that not only do diet drinks not help with weight loss, but they actually cause both weight gain and health problems.

Researchers from the University of Texas Health Science Center (UTHSC) at San Antonio gathered ten years worth of data on 474 participants from a larger, ongoing study called the San Antonio Longitudinal Study of Aging. Among these participants, those that consumed two or more diet drinks a day experienced waist size increases that were a staggering six times greater than those who did not consume diet drinks.

Helen P. Hazuda, a study researcher and professor at the UTHSC School of Medicine presented the study results at the annual meeting of the American Diabetes Association. She reported that: “Data from this and other prospective studies suggest that the promotion of diet sodas and artificial sweeteners as healthy alternatives may be ill-advised. They may be free of calories, but not of consequences.”

The findings debunk the false notion that switching to diet drinks will help you lose weight. What they do show is a 70 percent increase in waist size compared to those who do not drink them, so it is not clear how calling them ‘diet’ is applicable.

I have mentioned the health dangers of aspartame before, and a related study presented at the same time, found that this chemical sweetener commonly found in diet foods and drinks, is actually responsible for raising blood sugar levels.

This was an animal, not human study, but the results suggest that heavy aspartame exposure might potentially directly contribute to increased blood glucose levels. This could be a major contributory factor to the risk of diabetes, already a worldwide epidemic and growing.

A previous study had linked saccharin to weight gain and according to Dr. Marie Savard, medical contributor for ABC News, there is something about diet foods that changes your metabolic limit, your brain chemistry.The truth is, we’re putting artificial sweetener in so many different things: in water, in yogurt. We have to rethink what this artificial stuff does to us.”

This links to a previous 2010 study conducted by researchers from the National Institute of Diabetes and Digestive and Kidney Diseases that found that the body’s reaction to the ingestion of artificial sweeteners appears to be brain confusion over how exactly to process it, which in and of itself is implicated in causing various other negative consequences.

Certainly it is true that US Food and Drug Administration have had adverse event reports going back several decades that indicate that artificial sweeteners like aspartame are also responsible for destroying brain neurons, which in turn leads to a host of chronic illnesses. These include, but are not limited to, chronic headaches, seizures, strokes, vascular disorders, heart disease, premature birth, dementia and other brain disorders, and cancer.

So if you want a fizzy refreshing drink then please steer clear of diet ones, and for a low calorie option try sparkling mineral water with a few drops of vanilla essence in it for sweetness and flavor.

Smoking Does Not Keep You Slim – But There Is a Male/Female Difference

There are many health myths that we hold as truth: the last biscuit on the plate contains no calories, my grandfather drank a bottle of whisky every day of his life and died at 101 so alcohol won’t harm me and perhaps the most common is that smoking helps keep you slim so giving up means becoming hugely overweight.

In one of my previous jobs I was Press Officer to Northern Ballet and bizarrely as it seemed to me most of the dancers smoked. You would think needing the best stamina and lung capacity would militate against it but, particularly for the girls, it was seen as an easy way to suppress appetite and control weight.

Now new research from the Nordic School of Public Health (NHV) in Sweden shows that smoking doesn’t help you get thinner, despite what we may believe. While cigarette smoking has decreased in western countries, obesity has increased and recent studies have suggested that today’s smokers may have less weight problems than non-smokers. Lisa Webb, Master of Public Health at NHV, set up a study in which over 6,000 people have participated in a study on the relationship between smoking and obesity.

They used two measure of body fat: BMI (body mass index) and WHR (waist hip ratio) and what surprised them was the definite difference between the results for men and women. Compared with non-smoker, both male and female smokers had a higher WHR but women had a lower BMI.

So if you are looking to use not giving up smoking because you don’t want to put on weight, then that is no longer viable. One other interesting finding was that the difference between the WHR among female smokers and women who had never smoked actually increased during the study. So if you want to improve your waist hip ratio then giving up smoking will definitely improve your chances of that.

Got Diabetes? – Eat More Strawberries

Wimbledon may be over, but we are still in the wonderful English strawberry season and now there is a powerful health reason to eat more of them. A recent study from scientists at the Salk Institute for Biological Studies suggests that a strawberry a day could lessen the complications of diabetes. Or more accurately, the fisetin they contain as this naturally-occurring flavonoid is found most abundantly in strawberries.

Fisetin is a naturally-occurring flavonoid found most abundantly in strawberries, and to a lesser extent in other fruits and vegetables, and has been found to be able to target multiple organs. This research describes for the first time a drug that prevents both kidney and brain complications in a type 1 diabetes model and strongly suggests that a single drug could be used to mitigate numerous medical complications.

Fisetin was originally identified as a neuroprotective flavonoid ten years ago and in plants it act as sunscreen and protects leaves and fruit from insects. The types of fruit and vegetables containing fisetin are found in the ‘Mediterranean Diet’ and contribute to the protective effect of that regime.

The researchers evaluated effects of fisetin supplementation with reference to the serious complications of diabetes such as diabetic nephropathy or kidney disease, retinopathy, and neuropathies in which patients lose touch or heat sensations. Improvements were seen, but remember that to achieve a similar effect you would need to eat 37 strawberries a day so let’s hope they manage to turn the fisetin into a supplement form fairly soon.

Interestingly, the fisetin was also effective in mouse models of Alzheimer’s disease so there is certainly more research to be done.

In the meantime what about a strawberry and blueberry smoothie to get the maximum fisetin into your system in a palatable way?

An Alternative to Antibiotics

Antibiotics are among the greatest achievements of medical science, but we have learned to treat them with caution. This once-perceived all-purpose weapon has failed in the battle against infectious diseases and bacteria are increasingly developing resistance to antibiotics. The good news is that researchers have now found a therapeutic equivalent which could replace penicillin and related drugs.

The World Health Organization is warning about resistance to drugs which were once so potent as more pathogens are becoming immune to antibiotics and some bacteria can no longer be combated WHO figures show that in 2010 nearly half-a-million people were infected with a strain of tuberculosis which is resistant to many antibiotics and that one third of those infected died.

The growing spread of resistant pathogens is directly attributable to the indiscriminate use of penicillin and other antibiotics so congratulations to the Fraunhofer Institute for Cell Therapy and Immunology in Leipzig who have found an alternative to the established antibiotics. In the future, antimicrobial peptides will take up the battle against pathogens.

They have already identified 20 of these short chains of amino acids which kill numerous microbes, including enterococci, yeasts and molds, as well as human pathogenic bacteria such as Streptococcus mutans, which is found in the human oral cavity and causes tooth decay. Even the multi-resistant hospital bug Staphylococcus aureus is not immune, and in their tests its growth was considerably inhibited. Antibiotic peptides unlock their microbicidal effect within a few minutes and work at a far lower concentration compared with conventional antibiotics. Another key factor is that the peptides identified in the tests do not harm healthy body cells.

Not just us, but also our food could benefit from the antimicrobial peptides given that the bacterial contamination of food products costs the industry billions every year. Fresh lettuce, for example, are badly contaminated by yeasts and molds and this breakthrough means that the shelf-life could be improved by adding antimicrobial peptides during the production process.

We are still not there yet, so in the meantime if you want to fight infection and bacteria there are some natural aids you can use instead. Garlic, aloe vera and Echinacea have been in use for years and a relative newcomer is grapefruit seed extract which is a very powerful natural antibiotic.

How Dehydration Can Affect Allergies – 6 Simple Ways to Avoid It

If what summer means to you is stocking up on giant boxes of tissues and avoiding going out of doors, then there is a hidden factor that you may not be aware of. It seems that many allergy sufferers are also dehydrated, so that no matter how much water they drink they suffer from dry skin and a parched mouth.

Generally we are dehydrated as a nation, despite all those water bottles so ostentatiously displayed on desks and in gym bags. Studies estimate that 75% of us are prone to the ill health effects associated with chronic dehydration,. But what has that to do with your allergies? Well, allergies are caused by a histamine reaction in the bodyand histamine is an important neurotransmitter that primarily regulates thirst mechanism for increased water intake. It also establishes a system of water rationing for the available water in the drought-stricken body.”

When the body is dehydrated, histamine production increases significantly as its primary job is to make sure that the available water in the body is preserved for the most vital functions. It is the ‘drought mechanism’ if you like, and it creates a chain of events that affects numerous functions in the body, including the suppression of antibody production. This means that the body will simply not be as well equipped to deal with unhealthy invaders, such as pollen and other antigens.

That’s why during summer, when pollen season is in full swing, our eyes are invaded with the pollen agents, and the dehydrated body lacks the antibodies to adequately neutralize the pollen. So in response, the tear-producing glands of the eyes work overtime to wash the pollen away from the delicate membranes.

The histamine reaction and suppression of antibodies are just two of the many ways the body adapts to dehydration and although dehydration is not the only cause of allergies, it can be the primary cause. And the good news is that you can easily remedy it.

It can take time to fully rehydrate your body, but keep going as in the beginning a parched body – like dry ground – does not absorb all the water but it just runs out and away. It may seem like you are forever running to the loo in the early stages, but be persistent with your water intake and this will regulate as your starts to absorb and utilize the water better at the cellular level.

Top Water Retention Tips
1. Drink water – obvious but true – and plain, not carbonated. Not soft drinks or teas and coffees, but plain water.

2. Check the amount you drink, and the recommendation to rehydrate a dehydrated body, which is at least 1.5-2litres a day and during exercise or hot weather, you should increase your water intake significantly.

3. Don’t guess, but measure and record your water intake and that may be easier by setting out a number of bottles a day, or using a litre measuring jug and keeping track of how often you fill it. .

4. Filter your drinking water at source, at the tap, or in a filter jug or use reputable bottled water from a guaranteed source.

5. Little and often is best so make sure you drink regularly throughout the day as your body can only absorb about 12 to 16 ounces of water a time. The most important time to drink water is first thing in the morning so drink a large glass then, and add some fresh lemon juice to a detox start to the day. After breakfast have another large glass and try not to drink with meals, but in between so that you do not to dilute your digestive juices.

6. Unless you have high blood pressure, it can also help to add sea salt to drinking water because your more frequent urination means you are losing sodium. Not processed salt, and about a quarter teaspoon per litre will be plenty.. Salt itself is a natural antihistamine and if you add in a multimineral supplement then you will ensure proper electrolyte balance.

Don’t let your baby’s umbilical cord go to waste

A tricky subject this: in some parts of the world, particularly China, the placenta and umbilical cord area as valuable health resources but in the West we are rather more squeamish and the subject of stem cell research and implementation is still open to debate. However that cord could save a life, so in my usual fashion I am giving you information, and what you do with it of course is entirely up to you.

Future Health Biobank, the UK’s leading private family cord blood and cord tissue bank, is sending out a message to alert parents to the potential of their baby’s umbilical cord and don’t automatically let it go to waste. The umbilical cord blood is the richest source of the body’s stem cells, the important building blocks of life. Their job is to multiply and transform into the cells that make up our blood, bones, tissues, tendons, organs – in fact everything that makes us physically what we are. They can build from scratch but they can also restore and repair as we grow and age. These vital cells are already being used to treat thousands of people for an ever increasing list of medical conditions – currently some 85 different blood and immune system disorders. In fact the use of stem cell transplants is now standard medical practice in many countries.

Up until now, the most common source of stem cells has been bone marrow, but umbilical cord blood and tissue are much richer sources as well asbeing a much simpler and less invasive way to obtain them. After birth and the delivery of the placenta the cord is simply clamped and the blood is collected along with approximately 15cm of cord tissue if both samples are required. The whole procedure takes less than ten minutes and is completely painless.

One of the disadvantages in the use of bone marrow is the difficulty in finding the perfect match but with umbilical cord stem cells there is a 100 per cent match for the baby and a high probability of a match with siblings, parents and perhaps even grandparents. For families with a history of cancers or many other diseases the availability of stem cells can be a life saving resource and scientists are now investigating ways to use the specialised stem cells in cord tissue which can differentiate into bone, cartilage, tendon or muscle and even nerve tissue. These stem cells also appear to have immunosuppressive properties and thus may be able to combat chronic inflammation.

If you think this is something you might want to do, then if the birth is going to take place at an NHS hospital which is linked to either the UK’s public cord blood bank or the Anthony Nolan Trust, then you can ask for the umbilical cord blood to be donated. However this is not nationally available so for the majority of parents-to-be the only realistic option is to consider a private collection , particularly if they wish to save the cord tissue as well as cord blood as this is not currently collected for the public bank.

93% of Unborn babies found to have GMO toxins

If you thought that the fuss over GM crops was over the top then maybe this new study from Canada will make you change your mind. The biotechnology industry has always claimed that a certain genetic pesticide used in the cultivation of genetically-modified (GM) crops does not end up in the human body upon consumption. Not true.

Researchers from the Department of Obstetrics and Gynecology at the University of Sherbrooke Hospital Centre in Quebec, in Canada have proved that Bt toxin, which is used in GM corn and other crops, definitively makes its way into the blood supply and was found in the bloodstreams of 93 percent of the pregnant women they tested.

If you are feeling complacent because you don’t eat GM modified foods then their study – which was just published in the journal Reproductive Toxicology – reveals that Bt toxin enters the body not only through direct consumption of GMOs, but also from consumption of meat, milk and eggs from animals whose feed contains GMOs. And that is virtually impossible for you to monitor on an individual basis. Among all women tested, 80 percent of the pregnant group tested positive for Bt toxin in their babies’ umbilical cords, but also a staggering 69 percent of non-pregnant women also tested positive for Bt toxin.

GM crops have been given approval in many countries because it was believed (and heavily promoted) that they were the same as conventional crops. The biotechnology industry has claimed for years that the alterations and chemicals used in GM crop cultivation pose no risk whatsoever to human health, and that any GM substances that remain in food are broken down in the digestive system. Now that it has been revealed that such claims are untrue many pressure groups are urging governments to pull GMOs from their food supplies.

“This research is a major surprise as it shows that the Bt proteins have survived the human digestive system and passed into the blood supply — something that regulators said could not happen,” said Pete Riley from GM Freeze, an alliance of organizations united against GMOs. “Regulators need to urgently reassess their opinions, and the EU should use the safeguard clauses in the regulations to prevent any further GM Bt crops being cultivated or imported for animal feed or food until the potential health implications have been fully evaluated.”

I am always wary of research that is funded by the interested parties, and most of the studies that have been used to validate the safety of GMOs have been conducted by the companies that created them in the first place. This does not, to me, make them a credible source for reliable safety data. Although Governments in North and South America, as well as throughout Europe, have essentially welcomed GMOs into the food supply this was based on evidence and reassurances from the companies themselves, and with this new independent study it certainly seems to be time to reassess the situation.

The easier and immediate solution is wherever possible to eat local organic, certified foods where you know their source or point of origin and ensure a reasonably high level of vitamin C intake (500-100mg a day) to help flush toxins from your system.
