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.

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.

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.

You truly do learn something new everyday, regardless of how old you are. Today is the first time I heard of smoke vaporizers, at first I thought it was some sort of alien phaser weapon but I soon learned it is an interesting technology for smoking without actually smoking? Does that makes sense?

Smoking with a vaporizer rather than through the traditional method is supposed to be more beneficial because no smoke is being inhaled. Using cheap lightbulb vaporizers you can actually take in the pure fumes and studies have been done to show that when used to consume medical marijuana, a vaporizer shows even greater benefits.

Health in parts of rural China is deteriorating despite rising incomes, and commercialised care has ratcheted up costs for those who can least afford them, the head of the World Health Organisation said on Thursday. Hong Kong-born Margaret Chan said the cost of health care in China was outstripping income growth and that poor health was a major cause of poverty among China’s hundreds of millions of rural residents.

The costs of seeing a doctor or staying in hospital are out of reach for many in the world’s fourth-largest economy, and the lack of access combined with corruption has made the issue a source of social unrest. China has pledged to provide its population with basic medical care by 2020, but Chan said the government was receiving little return in the form of better health for its investment in the sector.

“When ability to pay determines access, many rural residents will not seek care until a disease has reached an advanced stage when treatment is more complex and costly, if not impossible,” she said. “In short, the health system in rural areas has been given multiple incentives to operate with great inefficiency.”

That could undermine China’s efforts to expand care through its Rural Cooperative Medical Scheme, a plan under which subscribers are funded at a level of 50 yuan per person — 20 yuan from the central government, 20 from the local government and a 10 yuan contribution from the individual.

Chinese Vice-Minister of Health Chen Xiaohong said nearly 85 percent of counties in China were participating in the plan but the funding level paled to that of wealthy coastal cities. China was also facing new pressures in the health sector, from an ageing population and environmental risk factors, as well as the challenge of drawing doctors to practise in its rural interior.  I hope the Chineese government gets its’ act together and starts taking care of some of it poorest citizens.

A modern day world record is set.  A small Russian city just got a really big addition: a 17-pound, one ounce baby whose mother had already delivered 11 other children.   Tatiana Khalina, 42, delivered the girl by caesarean section at a maternity clinic in Aleisk, a town of 30,000 people in the Altai region in southern Siberia, a nurse at the clinic said Thursday.

Nurse Svetlana Gildeyeva also said the Sept. 17 birth went smoothly, and mother and the child were fine. She said the baby, Nadezhda, was transferred from the small clinic to a maternity hospital in Barnaul, a larger city.  The girl was feeling well and developing normally, said Irina Kurdeka, a doctor at the hospital in Barnaul.

The Moskovsky Komsomolets newspaper quoted the local social services chief, Marina Alistratova, as saying the family had modest means. She said Khalina’s husband was on contract with a local military unit.   “We have presented them with a good washing machine, a food package and a card,” Alistratova told the newspaper. “We will keep supporting them in the future.”

An average weight for newborn babies is around 7 pounds, one ounce, according to international statistics.   Guinness World Records says the heaviest baby ever was born in the United States in 1879. It weighed 23 pounds, 12 ounces and died 11 hours after birth. Guinness says they heaviest surviving baby was born in 1955 in Italy, weighing in at 22 pounds, eight ounces.   The only thing I could think of was OUCH!

So here is the scoop. One of my best friends is pregnant and me being a guy I don’t have much first-hand experience so I need to find out some information in order to be as supportive as possible. I searched the web and came across a virtual all-in-one pregnancy site. It really does have everything you need to know, starting from the stages of conception all the way to birth.

My friend says twins run in her family and I was even able to find specialzed information topics like twins complications, best to be prepared for anything. I will let you know how everything ‘comes out’ in around 7 more months!
