A new patch just created will one day monitor a person’s health using minuscule sweat samples. The patch is being developed by Biotex, a consortium of European research institutes and companies, including the Swiss Centre for Electronics and Microtechnology (CSEM).

Most clothing designed for health monitoring focuses on physiological measurements, such as body temperature and heart rate. This is one of the first attempts to continuously analyze biochemical signals using clothing. The team employed a novel approach for monitoring: a combination of hydrophilic and hydrophobic yarns woven together to channel the sweat to the sensors. By utilizing natural attraction and repulsion actions to move the sweat, the method also circumvents the need for additional power sources, which would add bulk to such a device and make it less convenient for everyday use.

Once the fabric has directed a few milliliters of sweat into the patch, the sensors determine the amount of potassium, chloride, or sodium present. Measuring these electrolytes can provide insight into a person’s metabolism. By comparing the electrolyte amounts to reference measurements, such a system could indicate if the user is overexerting herself or stressed, says Jean Luprano, project coordinator at the CSEM.

Once the tiny reservoirs are full of sweat, the user throws away the chemical part of the patch, which is about 5 to 10 square inches. The patch-embedded band or shirt can be washed, and the monitoring electronics reused.  This sounds like sci-fi but it reminds me if the new terminator tv show where the robot can diagnose your physical health by tasting your sweat.

Scientists have pinpointed genetic variations that make people more likely to get hooked on cigarettes and more prone to develop lung cancer — a finding that could someday lead to screening tests and customized treatments for smokers trying to kick the habit.

The discovery by three separate teams of scientists makes the strongest case so far for the biological underpinnings of nicotine addiction and sheds more light on how genetics and lifestyle habits join forces to cause cancer. A smoker who inherits these genetic variations from both parents has an 80 percent greater chance of lung cancer than a smoker without the variants, the researchers reported. And that same smoker on average lights up two extra cigarettes a day and has a much harder time quitting than smokers who don’t have these genetic differences.

The researchers disagreed on whether the variants directly increased the risk of lung cancer or did so indirectly, by causing more smoking. The three studies, funded by governments in the U.S. and Europe, are being published Thursday in the journals Nature and Nature Genetics.

The scientists studied the genes of more than 35,000 white people of European descent in Europe, Canada and the United States. Blacks and Asians will be studied soon and may yield different results, scientists said.They aren’t quite sure if what they found is a set of variations in one gene or in three closely connected genes.

The gene variations, which govern nicotine receptors on cells, could eventually help explain some of the mysteries of chain smoking, nicotine addiction and lung cancer. These oddities include why there are 90-year-old smokers who don’t get cancer and people who light up an occasional cigarette and don’t get hooked. The smoking rate among U.S. adults has dropped from 42 percent in 1965 to less than 21 percent now.

The new studies are surprising in that they point to areas of the genetic code that are not associated with pleasure and the rewards of addiction. That may help explain why some people can quit and others fail, said Dr. Nora Volkow, director of the National Institute of Drug Abuse in Bethesda, Md., which funded one of the studies.

One clue is in the location of the just-discovered variants, on the long arm of chromosome 15, Volkow said. It is in an area that, when damaged during tests on animals, makes them depressed and anxious. While some people smoke because it helps them focus or gives them a physiological reward, others do it to stave off depression.

That suggests that adding antidepressants to some smokers’ treatment could help them kick the habit.  Anti-depressants have been used for quite a while now but I guess they did not know exactly why they worked.

This one is a goldie oldie but it sure is shocking to see nowadays:

Crazy!

Often as you get older or due to medical conditions, it can become harder to navigate staircases. This can greatly hinder your ability to fully enjoy and utilize your home. When it has become impossible or just unsafe to travel up and down the stairs it is no longer necessary to think about buying a new home or just not using part of your home.  Stair lifts can help you to regain your freedom and independence.

There are many different types of stairlifts. For most people the seated stair lift offers the best way to regain their freedom. A seated stair lift offers a 180 degree swivel seat with liftable armrests that allow the user to easily enter and exit the stair lift. A quality stair lift will also have a seat belt for added safety.

The installation of these products is generally simple and can be done in a few hours with common household tools. However, in instances where your staircase is unusually narrow or if you have a spiral staircase you should consider having the stair lift professionally installed. For heavy duty stairlifts intended for commercial use some states, like WA and CT, now have local code requirements when installing these devices.

Nowadays our life is getting more and more tense. People live under constant stress of various problems, such as social, ecological, economic and etc. We constantly suffer from noise and dust in big cities, diseases and instability. To overcome all difficulties we should take care of our physical and mental health.To achieve this aim it’s better to keep to a balanced diet and take prescribed supplements from a vitamin store. To my mind there is no ideal diet for all people in general because our food needs differ according to age, sex and occupation. For instance, Women’s Health Magazine claims that the ideal diet contains different types of foods in such quantities and proportions that the need for calories, minerals, vitamins and other nutrients is adequately met in our bodies and provides them with energy for all life processes and for the growth, repair and maintenance of cells and tissues.

Fluid intake in the form of water based drinks is also essential for good health. Water is essential for the correct functioning of kidneys and bowels. The famous medical specialist Jacob Bogatin thinks that at least 6-8 glasses of plain water should be drunk each day, more in hot weather.

According to Women’s Diagnostic Center in Philadelphia: there are also various factors that need to be kept in mind while you are working out the ideal diet for yourself. They are: natural qualities of each food, places and climate where the food is grown prepared and consumed. You should not forget about the presence of artificial flavors, chemicals and preservatives.

In conclusion I’d like to say that following a well-balanced diet regularly and staying at your ideal weight are crucial factors in maintaining your emotional and physical well-being.

Unless you have been living under a rock you have probably heard of the newest and loudest calls for more action against steriod abuse. Roger Clemens and a host of others have went before a Senate committee and it seems there are quite a few sparkling lies flying around. Anabolic steroids have many legititmate medical uses and you can indeed buy steriods everywhere but they have been plastered everywhere because of it’s abuse by proffesional athelets.

It is interesting to note that a couple of years ago when Governor, movie star former professional bodybuilder and all-around celebrity Arnold Schwarzenegger admited to using steroids and said he has no regrets. “I have no regrets about it,” said Schwarzenegger, “because at that time, it was something new that came on the market, and we went to the doctor and did it under doctors’ supervision.” The bottom line is do your research and don’t abuse them.

Medtronic on has received federal approval to sell its drug-coated stent, the first to hit the U.S. market since safety concerns sank their popularity two years ago.  The Food and Drug Administration said it cleared the company’s Endeavor stent for use in patients with clogged arteries. Medtronic said it expects to ship 100,000 units to hospitals in February.

Endeavor is one of a new generation of stents the industry hopes can rejuvenate U.S. demand for the drug-oozing devices, sales of which plummeted to $2 billion last year, down from a peak of $3.1 billion in 2005.

Stents are tiny, mesh-wire tubes that prop open arteries after they have been surgically cleared of fatty plaque. They became one of the most lucrative medical devices in modern history after companies began adding drug coatings to stents in 2003 to prevent blood clotting.

An estimated 6 million people worldwide have had one implanted.  Hopefully this new one is going to be problem free.

The arguement about the health benifits of milk have been raging for years.  One website even goes as far as to say “Milk is a deadly poison,”. If you visit the site, notmilk.com, you’ll find dozens of articles about the purported evils of this popular beverage. One claim, for example, is that milk from cows contains cancer-causing hormones and dairy industry dollars have kept that fact bottled up. All of which may leave you second-guessing your next sip.

However, as a nutritionist, I’ve found that most people thrive on milk, whether their goal is to lose fat or build muscle. So to be sure it’s safe, I’ve investigated all the anti-milk claims, sifting through the research while also turning a critical eye to pro-milk propaganda. After all, the only agenda I have is my clients’ health. The result: all your milk questions, answered.

Is milk really a fat-burning food? Maybe. In a 6-month study, University of Tennessee researchers found that overweight people who downed three servings a day of calcium-rich dairy lost more belly fat than those who followed a similar diet minus two or more of the dairy servings. In addition, the researchers discovered that calcium supplements didn’t work as well as milk. Why? They believe that while calcium may increase the rate at which your body burns fat, other active compounds in dairy (such as milk proteins) provide an additional fat-burning effect. Of course, the key to success is following a weight-loss diet to begin with. After all, downing your dairy with a box of doughnuts is no way to torch your gut.  Personally I would like to see some additional studies to confirm these findings.
