Pregnant Polar Bears Hold The Key To Preventing Osteoporosis

Three months before giving birth, the pregnant polar bear retreats to a maternity den dug deep in a snow drift.

There she hibernates, conserving her energy before she has her cubs - and while she suckles them.

During her six-month confinement, the bear does not eat or drink and barely moves. But despite this, her bones remain strong - while large amounts of new bone are made.

This remarkable ability to stop her bones from wasting away could help tackle osteoporosis, scientists believe.

The condition, in which old bone is broken down faster than new bone is made, is most common in old age but can also hit those bed-ridden by ill-health.

If experts can work out how polar bears keep their bones strong during hibernation, they may be able to develop better treatments for osteoporosis, or even drugs to prevent it.

Experts from the Royal Veterinary College, in Hertfordshire, and University College London, have been monitoring 21 pregnant bears in Hudson Bay, Canada.

Only the pregnant animal hibernates. Blood samples showed that they ratchet up bone production before going into hibernation.

Renewal of bone remains high during hibernation - despite the drain on the body of pregnancy, labour and suckling.

As a result, the mother emerges from the den with bones as strong as when she went in, the BBC natural history website LoveEarth.com reports.

Usually, physical activity boosts bone production and bones tend to weaken when animals are immobile for long periods.

Bedridden humans can wait years for their bones to recover.

Regularly Eat Fish To Cut Sudden Coronary Death

Eating fish rich in omega-3 fatty acids may help prevent sudden coronary death, Dutch researchers report.

But the occasional slab of salmon or other fatty fish may not do the trick; following a fishy diet for the long run may be more effective, according to the researchers, who included Martinette Streppel, MSc, of the Netherlands' National Institute for Public Health and the Environment.

Streppel's team studied 40 years of data on 1,373 Dutch men age 40 and older.

Men who reported eating an average of 6 grams of fatty fish daily -- that's two servings, according to the U.S. Department of Agriculture's serving-size guidelines -- were 55% less likely than men who ate no fatty fish to die of sudden coronary death.

Those benefits were strongest before age 50 and with long-term consumption of fatty fish.

The researchers chalk up the results to the omega-3 fatty acids EPA and DHA, found in fish including salmon and mackerel.

The Dutch study doesn't show exactly how much EPA and DHA it takes to prevent sudden coronary death, or what fish the men ate. But the findings show that eating lots of fatty fish may not be better than eating a moderate amount; the big gap was between fish eaters and those who don't eat fish at all.

Broccoli May Help Boost The Aging Immune System

Eat your broccoli! That's the advice from UCLA researchers who have found that a chemical in broccoli and other cruciferous vegetables may hold a key to restoring the body's immunity, which declines as we age.

Published in this week's online edition of the Journal of Allergy and Clinical Immunology, the study findings show that sulforaphane, a chemical in broccoli, switches on a set of antioxidant genes and enzymes in specific immune cells, which then combat the injurious effects of molecules known as free radicals that can damage cells and lead to disease.

Free radicals are byproducts of normal processes, such as the metabolic conversion of food into energy, and can also enter the body through small particles present in polluted air. A supercharged form of oxygen, these molecules can cause oxidative tissue damage, leading to disease — for example, triggering the inflammation process that causes clogged arteries. Oxidative damage to body tissues and organs is thought to be one of the major causes of aging.

A dynamic equilibrium exists in the body between the mechanisms that lead to increased free radical production and those antioxidant pathways that help combat free radicals.

"Our study contributes to the growing understanding of the importance of these antioxidant defense pathways that the body uses to fight free radicals," said Nel, a practicing clinical allergist and immunologist at the Geffen School. "Insight into these processes points to ways in which we may be able to alleviate the effects of aging."

The delicate balance between pro-oxidant and antioxidant forces in the body could determine the outcome of many disease processes that are associated with aging, including cardiovascular disease, degenerative joint diseases and diabetes, as well as the decline in efficiency of the immune system's ability to protect against infectious agents.

"As we age, the ability of the immune system to fight disease and infections and protect against cancer wears down as a result of the impact of oxygen radicals on the immune system," Nel said.

According to the UCLA study, the ability of aged tissues to reinvigorate their antioxidant defense can play an important role in reversing much of the negative impact of free radicals on the immune system. However, until this current study, the extent to which antioxidant defense can impact the aging process in the immune system was not properly understood.

"Our defense against oxidative stress damage may determine at what rate we age, how it will manifest and how to interfere in those processes," Nel said. "In particular, our study shows that a chemical present in broccoli is capable of stimulating a wide range of antioxidant defense pathways and may be able to interfere with the age-related decline in immune function."

The UCLA team not only found that the direct administration of sulforaphane in broccoli reversed the decline in cellular immune function in old mice, but they witnessed similar results when they took individual immune cells from old mice, treated those cells with the chemical outside the body and then placed the treated cells back into a recipient animal.

In particular, the scientists discovered that dendritic cells, which introduce infectious agents and foreign substances to the immune system, were particularly effective in restoring immune function in aged animals when treated with sulforaphane.

"We found that treating older mice with sulforaphane increased the immune response to the level of younger mice," said Hyon-Jeen Kim, first author and research scientist at the Geffen School.

To investigate how the chemical in broccoli increased the immune system's response, the UCLA group confirmed that sulforaphane interacts with a protein called Nrf2, which serves as a master regulator of the body's overall antioxidant response and is capable of switching on hundreds of antioxidant and rejuvenating genes and enzymes.

Nel said that the chemistry leading to activation of this gene-regulation pathway could be a platform for drug discovery and vaccine development to boost the decline of immune function in elderly people.

"This is a radical new way of thinking in how to increase the immune function of elderly people to possibly protect against viral infections and cancer," Nel said. "We may have uncovered a new mechanism by which to boost vaccine responses by using a nutrient chemical to impact oxidant stress pathways in the immune system."

Kim said that although there is a decline in Nrf2 activity with aging, this pathway remains accessible to chemicals like sulforaphane that are capable of restoring some of the ravages of aging by boosting antioxidant pathways.

The next step is further study to see how these findings would translate to humans.

"Dietary antioxidants have been shown to have important effects on immune function, and with further study, we may be adding broccoli and other cruciferous vegetables to that list," Nel said.

For now, Nel suggests including these vegetables as part of a healthy diet.

Nel said that these findings offer a window into how the immune system ages.

"We may find that combating free radicals is only part of the answer. It may prove to be a more multifaceted process and interplay between pro- and antioxidant forces," he said.

The study was funded by the National Institute on Aging, the UCLA Claude D. Pepper Older Adults Independence Center, and the National Institute of Allergy and Infectious Diseases.

World's First Monkey Embryonic Stem Cells!

Researchers have cloned monkeys and used the resulting embryos to get embryonic stem cells, an important step towards being able to do the same thing in humans, they report.

These could provide a ready source of human embryonic stem cells, which can be turned into any cell in the body and offer the hope of developing treatments for a range of diseases including Alzheimer's, Parkinson's and diabetes.

In addition to basic research to understand disease, human stem cells could be used to replace damaged tissue. The resulting tissue would be genetically identical to a patient's own tissue, so there would be little chance of rejection.

To make such stem cells scientists must first create a cloned human embryo, something that has proved difficult. Several animal species have been cloned, but until now the technique has not been very successful in primates - and creating usable stem cells from cloned embryos has so far only been possible in mice.

In their research, published today in the journal Nature, Shoukhrat Mitalipov's team at the Oregon Health and Science University made 35 cloned embryos and successfully extracted stem cells from two of them, eventually growing them into heart and nerve cells.

Mitalipov's team overcame two barriers - first cloning a primate, the group of mammals that includes monkeys, apes and humans, and then getting embryonic stem cells from the clone.

Mitalipov says the dyes used in cloning some animals are apparently toxic to primate cells.

The researchers used somatic cell nuclear transfer to generate cloned embryos, the same method that famously led to Dolly the sheep.

The technique involves taking the nucleus from an adult cell, in this case fibroblasts, a type of skin cell, taken from nine adult males.

Then an egg cell is hollowed out and the nucleus from the adult cell inserted.

This programs the egg into behaving as if it had been fertilised and it can grow into an embryo.

It was not easy. The researchers used 304 eggs from 14 rhesus macaque monkeys and ended up with just two stem cell lines.

This means a lot more work before this would be useful for humans, they say, especially given how hard human eggs are to come by.

Tests show the embryonic stem cells are truly pluripotent, Mitalipov says, meaning they can develop into any kind of cell found in the body.

"We have been able to develop them into heart cells," he says. They also grew nerve cells.

It was important to confirm the work. The rival journal Science was forced to withdraw papers published by South Korean scientist Professor Hwang Woo-suk in 2004 and 2005 after his claims to have cloned a human embryo proved false.

Mitalipov says the team has tried, and failed, to produce cloned monkeys that could grow into live baby monkeys.

"We have a goal also of producing live monkeys using the somatic cell nuclear transfer technique," he says.

"One reason is to generate genetically modified macaques that, for example, carry a specific disease that is a model of human disease."

His team will not try to clone humans, he says.

"However we hope the techniques we develop will be useful for other labs which are working ... with human eggs," he says.

Inherited disease

Embryonic stem cells are the source of every cell, tissue and organ in the body.

Scientists hope to take a small piece of skin from a person to generate embryonic stem cells. These can then be programmed to grow tissue or even organ transplants perfectly matched to that person.

By making patient-specific cells, doctors could obtain cells whose genome would provide telltale clues of a disease.

These cells could be compared with healthy counterparts to see what is wrong, and a library of drugs could then be screened to see if a treatment is available.

All About Angina Pectoris

Millions of people around the world suffer from Angina pectoris, but only a few are aware of this condition and seek medical attention at the right time, before it worsens in to a severe heart attack. Angina pectoris or angina (a more commonly used term) is chest pain, which occurs when blood supply to the heart is restricted (because of conditions like arteriosclerosis), depriving it of oxygen and it is usually felt as a chest discomfort or heaviness / squeezing of chest.

Angina pectoris is a predecessor of myocardial infarction (heart attack) and should be treated immediately to reduce risks like heart attack or death.

In this video, Dr. Michael Farkouh, explains in detail about Angina pectoris, types and diagnosis of angina and the treatment options available to angina patients.

Why Before Surgery Smokers Should Stop Smoking

According to Ontario's Anesthesiologists smokers should cease their habit even for a short time to help curb the risk of complications both during and after any surgical procedure. To this end, Anesthesiologists have released a new campaign to get smokers to butt out before surgery. The campaign is called - Stop Smoking for Safer Surgery, and it is meant to be a public-patient awareness campaign.

Complications during and after surgery costs the Canadian health care system untold millions of dollars each year. Getting smokers to cease their habit, even for a limited time frame before and after surgery can save the health care system millions in needed money.

It has long been known that cigarette smoke contains very harmful elements such as nicotine and carbon monoxide amongst others. For those undertaking medical procedures, nicotine affects the heart by making it work harder than it should, thus consuming more oxygen, but the carbon monoxide prevents the blood from carrying the necessary oxygen to the heart. This combo leads to an increased risk of heart attack and/or other complications while under the influence of an anesthetic.

Dr. Stephen Brown, who is the Chair of Ontario's Anesthesiologists, says of the campaign, "Smokers are used to the health warnings on cigarette packets, to restrictions on smoking at work and in public, to warnings from their family physicians. To hear the message from an Anesthesiologist is probably something new for most smokers. The risks of pre-operative smoking are not widely known."

"Smokers are more likely to have heart problems during surgery and breathing problems after surgery. They heal more slowly and have an increased risk of wound infections," adds Dr. John Oyston, founder of the Stop Smoking for Safer Surgery initiative.

Doctors stress even a few hours of smoking cessation can reduce complication risks. "If a smoker quits prior to surgery, it will make their date with the surgeon less risky," explains Dr. Brown.

Smoke and Booze Can Demage Men's Sperm

Scientists say tests on rats showed sperm damage caused by exposure to garden chemicals remained up to four generations later.

Their findings have led them to warn fathers who smoke and drink to be aware they are potentially not just damaging themselves, but also their heirs.

The study by scientists from the University of Idaho in the U.S. suggests that a father's health plays a greater role in the health of future generations than has been thought.

The team led by Matthew Anway tested the effects of a hormone-disrupting fungicide chemical called vinclozolin on embryonic rats and found the chemical altered genes in the sperm, including some associated with human prostate cancer.

The rats exposed to the chemical showed signs of damage and overgrowth of the prostate, infertility and kidney problems and the defects were also present in animals four generations later.

The scientists admit that the rats were exposed to very high levels of vinclozolin but say their work shows that once toxins cause defects in sperm they can be passed down the generations.

Professor Cynthia Daniels, from Rutgers University in New Jersey, an expert on male and female reproduction, says it has been found that men who drank a lot of alcohol have increased rates of sperm defects and nicotine from tobacco also found its way into seminal fluid as well as blood.

Professor Daniels advises moderation for young couples and points out that substances which can have an impact on reproduction are often also carcinogenic.

Fertility experts say the DNA in sperm cells is more tightly packed than in other cells, and so, to some extent, is protected from damage, however, once sperm cell DNA is damaged, it has no mechanism by which to effect repairs.

They advise any man trying for a baby to lead as healthy a lifestyle as possible as heavy smoking and drinking undoubtedly results in sperm damage and possibly damage to the DNA of the sperm.

However the good news is that male sperm is produced continuously in a 74-day cycle, so the body does cleanse itself over time.

The study was presented to the American Association for the Advancement of Science (AAAS) in Boston USA.

A new Study Raises Doubts About Antidepressant Use

A new study suggests that the majority of patients with depression may not benefit from taking antidepressant drugs.

Researchers from the University of Hull reviewed data from a number of trials involving the drugs Prozac (fluoxetine), Seroxat (paroxetine), Effexor (venlafaxine) and Serzone (nefazodone).

They concluded that the drugs may only be of benefit in patients with very severe depression.

However, the drugs' manufacturers have downplayed the findings, pointing out that other reports have shown them to be effective.

Prozac manufacturer Eli Lilly issued a statement saying: 'Extensive scientific and medical experience has demonstrated that Prozac is an effective antidepressant.

'Since its discovery in 1972, fluoxetine has become one of the world's most-studied medicines. More than 40 million people suffering from depression have been treated with fluoxetine in over 100 countries around the world.'

Experts have also cautioned that patients on antidepressants should not stop taking their medication in light of the latest research.

Marjorie Wallace, chief executive of the mental health charity Sane, said: 'These results are focused on clinical effectiveness rather than health risks.

'It is important that people should not stop taking the antidepressants immediately, as doing so could lead to severe rebound depression.'

Bird Flu Breaks Confirmed in Tibet

Chinese authorities confirmed Tuesday the second bird flu outbreak in Tibet this year, a day after reporting a 22-year-old man in central China died from the virus.

Chinese authorities said the Tibetan outbreak started on 6th February, in a small community on the outskirts of Lhasa, the capital of Tibet, which lies in the Himalayas. The outbreak killed over 100 domestic birds, and since then nearly 8,000 more have had to be culled.Samples tested in the laboratory over the weekend have proved positive for the deadly H5N1 form of bird flu, according to a report in the Canadian Press, which also says that the authorities have brought in emergency measures in the area.The earlier bird flu outbreak was reported last month on a poultry farm in the southwest part of the province. That killed 1,000 birds and the farm was put under quarantine regulations.The 22 year old man who died of bird flu on the 24th of January was confirmed as having had the H5N1 virus, said China's Center for Disease Control and Prevention in Beijing. The man, whose name was Li, came from Jianghua County, Yongzhou City, in the central province of Hunan, and was taken into hospital on 22nd of January. His symptoms, fever and headache, started on 16th January. Although he was treated, his symptoms got worse and he died, according to reports from state media.The province is currently experiencing extreme traffic problems because of low temperatures and severe bad weather with ice, rain and heavy snow, which have also caused blackouts. When this happens it is not unusual for disease and illness rates to go up, but the authorities say they have remained steady so far.Also, no person who came into close contact with Li has developed symptoms, and they continue to be kept under close medical observation, said the Chinese authorities.Last month China reported a case of a father and son who had caught bird flu, but officials said that although this was China's first case of bird flu in the same family, there was no evidence that the virus had passed from human to human. The son died early December 2007.According to Xinghua news agency, the new case has now been reported to the World Health Organization (WHO), and also authorities in Hong Kong, Macao and Taiwan, as well as other foreign governments.World experts in bird flu suggest it is only a matter of time before the deadly H5N1 virus mutates into a form that passes from human to human as opposed to bird to human. When it does so, they predict a world pandemic will kill millions of people.According to the WHO, as of 15th February, China has reported 27 confirmed casese of bird flu since 2003, including 17 deaths. Mr Li's death brings the death toll in China to 18.Meanwhile in Viet Nam, the Ministry of Health confirmed last week, that a 40 year old man from Gia Loc district, Hai Duong province, died of H5N1 bird flu on 13th February after being taken into hospital 5 days earlier. He developed symptoms on the 2nd of February and it has been confirmed that he had come into contact with sick and dead domestic birds before falling ill.

Babies Can Have Aids Virus through Pre-Chewed Food

For the first time, health officials report that the AIDS virus can be passed from an infected mother to her baby if she pre-chews the child's food as sometimes occurs in developing countries.Three such cases were reported in the United States :two in Miami and one in Memphis, Tennessee in which a child was infected in this way between 1993 and 2004. The mother was involved in two of the cases and a relative who acted as a caregiver was involved in the third.

It's blood, not saliva, that carried the virus because in at least two of the cases the infected mothers had bleeding gums or mouth sores.In developing countries, some mothers pre-chew food for babies. These women may lack access to packaged baby food or may not have a way to blend baby food.Centers for Disease Control and Prevention officials say more study is needed. But they are asking parents and caregivers with HIV not to pre-chew infants' food, and are trying to educate doctors about this kind of transmission.

The researchers said HIV transmission appears to have occurred when the children ingested pre-chewed food that contained blood from the bleeding gums of HIV-infected women, and this entered the children's bloodstreams through a cut, sore or inflammation of the mouth or digestive tract.They said they ruled out other possible means of infection such as breast-feeding or blood transfusion.

The first involved a 15-month-old African-American boy in Miami, diagnosed in 1993. His great-aunt was infected with HIV and pre-chewed food for the boy when he was between the ages of 9 months and 14 months.

Then a girl, age 9 months, was diagnosed with HIV in 2004. The HIV-positive mother reported giving pre-chewed food to the child, who is still alive, receiving HIV drugs.

In a third case a 3-year-old Caribbean-American boy was diagnosed in 1995, also in Miami. His HIV-infected mother pre-chewed food for her son.

All three children were infected with HIV at a time they would have been teething and had inflamed gums. It may be that both a caregiver and a child must have wounds in their mouths for the virus to have a good chance of passing from one bloodstream to another, the investigators said.

"The researchers advise that health care providers and HIV-infected child caregivers should be aware of the potential health risks and should advise those caregivers against the practice of pre-chewing food for their infants," the CDC said.

"This would really take a lot of thinking before you could say, 'We've had three cases in 11 years, so you have to stop pre-chewing your child's food,'" Hagen said.

Teenager With Four Kidneys Plans To Donate

A teenage girl who discovered she has four kidneys has decided to donate her two extra organs to patients desperately in need of a transplant. This girl,Laura Moon,18 years, is one of a tiny number of people to have four of the organs growing naturally. She only became aware of her unusual anatomy six months ago after undergoing an ultrasound scan to investigate stomach pains following a car crash.

The doctor even asked to take photos to show his university students.

Laura Moon is looking into becoming a live donor after hearing about Leeds resident Luke Heppenstall, 3, who urgently needs a new kidney after both of his were removed because of cancer.

Laura, who is about to start work as a customer services adviser, heard about three-year-old Luke Heppenstall, who urgently needs a new kidney. It occurred to her that if she had four kidneys and did not need all of them, she might be able to donate two to someone who did.

Transplant surgeon Niaz Ahmad of Leeds Teaching Hospitals NHS Trust, said he had never seen anyone with four full kidneys."To have completely duplex kidneys on both sides is extremely rare," he said.

Guide to Buying Chocolate For Diabetic Person's

To help you decide among all the options out there, we taste-tested a number of sugar-free chocolate products (and some portion-controlled ones, too). But first, let's talk about how having a little chocolate every day could actually be good for you.

Chocolate have some health benefits,studies have indicated that cocoa and darker types of chocolate may help reduce the risk of cardiovascular disease, decrease blood pressure, and relax blood vessels.

Many of the health benefits of chocolate seem to stem from the antioxidant flavanols which are also found in other plant foods including tea, grapes, grapefruit, and wine. The cocoa bean happens to be extraordinarily rich in them.

The first thing I learned while surveying the sugar-free chocolate market was that certain drug stores and supermarkets each stock certain brands of sugar-free chocolate. So, if you're looking for a certain brand, keep going to different stores.
I also soon discovered that the sugar replacement du jour for sugar-free chocolates is maltitol (a sugar alcohol). Almost all of the companies who make sugar-free chocolates are using it.

Sugar-free doesn't mean saturated-fat free, or calorie-free. Chocolate tastes so good because of two things: the sweet ingredient (maltitol, in the case of sugar-free chocolate), and cocoa butter. And cocoa butter is rich in saturated fat. For example, five pieces of Russell Stover Sugar Free Chocolate Candy Miniatures add up to 190 calories, 14 grams of total fat, and 9 grams of saturated fat.

If you don't want to go sugar-free, the trick is enjoying your chocolate (preferably the flavanol-contributing dark chocolate) in small portions. And you can easily find portion-controlled chocolate options, whether you choose mini-bars, kisses, or "nuggets."

One of the more nutritious and satisfying dark chocolate options out there is Hershey's Special Dark Nuggets with Almonds. This way, you get some nutritious almonds along with your dose of dark chocolate. If you can be satisfied with 2 of these "nuggets," (19 grams) this would add up to 110 calories, 7 grams of fat, 3 grams of saturated fat (0 trans fat), 10 grams of carbohydrate and 1.5 grams of fiber and 1.5 grams of protein.

Why Black Man Risk For Kidney Disease ?

Black men with kidney disease and high blood pressure are more likely than others to not have their blood pressure under control, which could worsen their kidney disease, according to a study in the current issue of the American Journal of Kidney Diseases, HealthDay News/U.S. News & World Report reports.

Among people in the later stages of kidney disease, both black men and women were less likely than white men and women to have their blood pressure under control.
High blood pressure can worsen kidney disease, and some research suggests that controlling hypertension may play a major role in slowing progression of kidney disease, according to background information in the study, which looked at more than 10,000 people with kidney disease and hypertension.

In a statement, Duru said, "African-Americans with (kidney disease) progress more quickly to kidney failure, at which point they must receive a kidney transplant or regular dialysis to survive," adding, "These findings suggest that their higher risk of kidney failure may stem, at least in part, from higher rates of uncontrolled high blood pressure."

About 26 million Americans have kidney disease. People at increased risk for kidney disease include minorities, older adults and those with diabetes, high blood pressure, cardiovascular disease and a family history of kidney disease. Research has shown that blacks with kidney disease progress five times faster to kidney failure than whites with kidney disease.

Many Snack Foods are Now Free of Artery-Clogging Trans Fat

Many snack foods and spreads on the market are now free of artery-clogging trans fat, but consumers still need to be savvy label-readers, according to researchers.
In a sampling of packaged foods at a local Wal-Mart, researchers at the University of Minnesota in Minneapolis found that a majority of margarines and butters, cookies, cakes and snack foods had gone trans fat free.
However, a number of products still had substantial amounts of the fat, the researchers report in the Journal of the American Dietetic Association.
For example, three of 40 brands of chips, crackers and popcorn contained at least 3 grams of trans fat per serving, according to the products' labels.
So, despite the food industry's move toward cutting trans fat, consumers still need to check labels, according to the researchers, led by graduate student Matthew J. Albers.

Trans fat has become notorious because it not only raises "bad" LDL cholesterol, but also lowers heart-protective HDL cholesterol. The main source of trans fat in the diet is the partially hydrogenated oil used in many commercially prepared baked and fried foods -- including cookies, crackers, chips, breads and french fries.
Since 2006, food manufacturers have been required to list trans-fat content on products' "Nutrition Information" labels. That has spurred many brands to cut the fat out.
In their study, conducted in July 2006, Albers and his colleagues found that 21 of 29 margarines and butters were labeled as containing 0 grams of trans fat. The same was true of 34 out of 44 cookies and snack cakes, and 31 of 40 savory snacks -- chips, crackers and popcorn.

A brand of butter, for example, might have less trans fat than the margarine next to it, but contain significantly more saturated fat.

How To Reduce Stress And Cholesterol

Diet and lifestyle could be the most important way to lower high cholesterol and the risk of coronary heart disease. Emphasis on a healthy diet and lifestyle is crucial both for those who are at low risk but have many years ahead of them, and also for those who are older and at a higher risk.

According to experts, there are four basic ways to get your cholesterol where you want it:
-Exercising
-Taking medicine -- in some cases
-Losing weight
-Eating a healthy diet
While each of these works, some people have more success with one than another. Many need a combination of approaches.
You've probably heard it before, but foods that are high in saturated fat and -- to a lesser extent -- high in cholesterol, boost your cholesterol levels. These include foods like egg yolks, fatty meats, and full-fat dairy products.
Exercise is a key component to lowering cholesterol, either by losing weight or maintaining a healthy weight. Excess fat and calories are a significant cause of high cholesterol, and it's necessary to balance intake of calories with a corresponding output of physical activity.

Exercise is another way to improve your cholesterol levels. Increased physical activity can have a modest effect on cholesterol, lowering triglycerides (and bad LDL cholesterol to a lesser extent), while boosting your good HDL cholesterol.
Of course, the type of exercise is up to you. Plotzky says just about any aerobic activity -- something that boosts your heart rate -- is good. Blumenthal says that walking is often the best way for people who are out of shape to get started.

The Future Of Stem Cells:Informations

Stem cells are special cells that can turn into many different cell types in the body such as heart muscle cells, brain cells, and skin cells. Stem cells taken from embryos that are just a few days old, can turn into any of the 300 different types of cell that make up the adult body.

Embryonic stem cells can be taken from spare human embryos left over from fertility treatments, or from cloned human embryos developed in the laboratory. This can only occur if fully informed consent has been obtained from the donors. One method for making cloned embryos is called nuclear transfer. During this process, genetic material or DNA from a donor is inserted into an empty egg cell.

Stem cells for therapeutic use can be obtained from three potential sources:

-Embryonic

-Umbilical Cord Blood

-Certain Adult Tissues

In future it is hoped that stem cells could be used to treat and cure a variety of diseases and injuries including Parkinson's disease, stroke and diabetes.Because stem cells are so versatile, they could potentially be used to repair and replace damaged human tissue.

There are two kinds of stem cells:

-Embryonic Stem Cells :cells found early in the development of an embryo that can progenerate a developing fetus and ultimately a human baby

-Adult Stem Cells:Adult stem cells are found in the human body and in umbilical cord blood. The most well known source of adult stem cells in the body is bone marrow but they are also found in many organs and tissues.

There is some evidence suggesting that adult stem cells also have this ability. An adult stem cell that has been assigned to become a vascular system cell may, in fact, reassign to become a kind of nerve cell under the right conditions. This has not yet been proven conclusively.

More About Bad Breath

Bad breath can cause embarrassment, create social and psychological barriers , and even affect marriages. Can result from poor oral hygiene habits and may be a sign of other health problems. Bad breath can also be made worse by the types of foods you eat and other unhealthy lifestyle habits.

People who have periodontitis often experience bad breath because of bacteria accumulating in areas that are not cleaned easily, such as deep pockets around teeth.

Bacterial plaque and food debris accumulate on the back of the tongue. The tongue's surface is extremely rough and bacteria can accumulate easily in the cracks and crevices. Large amounts of sulfur compounds can be produced in this area, making it a frequent site of origin for bad breath.

All the food you eat begins to be broken down in your mouth. As foods are digested and absorbed into your bloodstream, they are eventually carried to your lungs and given off in your breath. If you eat foods with strong odors (such as, garlic or onions), brushing and flossing - even mouthwash - merely covers up the odor temporarily. The odor will not go away completely until the foods have passed through your body.

You can reduce bad breath if you:

-Brush twice a day with fluoride toothpaste to remove food debris and plaque. Brush your teeth after you eat .Don't forget to brush your tongue, too. Replace your toothbrush every 2 to 3 months. Use floss or an interdental cleaner to remove food particles and plaque between your teeth once a day.

-Stop smoking

-Drink lots of water. This will keep your mouth moist. Chewing gum also stimulates the production of saliva, which helps wash away food particles and bacteria.

-See your dentist regularly – at least twice a year. He or she will conduct an oral examination and professional teeth cleaning and will be able detect and treat periodontal disease, dry mouth, or other problems that may be the cause of bad mouth odor.

-Oral infections must be eliminated or impacted teeth may need to be removed.

Five Foods for Better Health and Natural Weight Loss

Weight loss is a concern for most Americans. Whether you’re struggling with those final ten pounds that never seem to budge or you have many excess pounds that are having a negative impact on our overall health, it’s time to make a change.

I recommend reading through the following weight loss tips before choosing one or two to start with.

1.)Salmon - Salmon is one of the most popular “weight loss foods” around, and for good reason. It provides a hefty dose of healthy omega-3 fats, a hefty dose a metabolism boosting protein, and a nice dose of natural vitamins and minerals. Salmon, like the other power- packed super weight loss foods above also provides lengthy satiety, meaning less cravings. Salmon makes a great solid meal for lunch of dinner .Omega-3 fats are top notch in that they provide such a myriad of health benefits, it would take volumes to explain. Not only are they healthy, but omega-3’s have been shown to also boost metabolic rate, resulting in faster weight loss.

2.)Cottage cheese -Cottage cheese is here for slightly different reasons. Since it is a dairy product, cottage cheese contains quality amounts of calcium, which in recent studies has shown to tip the scales in terms of weight loss.

Cottage cheese is great for times when you may go for 3 or 4 hours without eating something. It is also great for a before bed snack. Many people tend to crave sweets before bed. Mixed with a small serving of fresh fruit, cottage cheese can quench your sweet tooth and provide ample amino acids for a good nights sleep.

3.)Beef -Beef is high in protein, which provides the amino acids necessary to maintain and build muscle fiber which is crucial to boosting your metabolic rate.Beef also provides a moderate amount of fat. Yes, I hear the collective “yikes!”. Hold on a minute though. What you think might be a negative is actually very positive for your health, and your weight loss journey. There is a revolution happening in the medical and fitness communities in views towards fat, saturated fat and cholesterol.

Beef also takes longer to digest than other foods, meaning less cravings as well.

4.)Blueberries-Blueberries are a sort of superfood. They contain very high amounts of antioxidants, which can help stave off cancer and other degenerative diseases.

Obviously a good dieter will also be performing some intense exercise to get their weight down, which will in turn boost these damaging free radicals. Eating your blueberries will provide the antioxidants which quell the free radicals, which in turn reduces soreness from the exercise.

5.)Broccoli-Broccoli is another high fiber vegetable, packing a solid satiating punch any time of the day. Broccoli is a wonder food in that it contains high amounts of antioxidants, much like blueberries, but contains so little calories that it’s considered negative calorie food. A “negative calorie food” basically means that it takes more energy to digest than it is providing.

Try dipping some fresh stalks into calorie free dip for a nice high fiber, high antioxidant guilt- free snack.

Complete eating at least 3 hours before sleeping. The body needs to fast in order to burn stored fat.

Don’t follow the “Sumo Diet” of consuming large quantities of food late at night when metabolism is at its lowest. Eat a large breakfast or lunch and a small dinner of salad, soup, vegetables or a highly nutritious shake.

Hair Loss:Causes

Our hair is made of a type of protein called keratin. A single hair consists of a hair shaft (the part that shows), a root below the skin, and a follicle, from which the hair root grows. At the lower end of the follicle is the hair bulb, where the hair's color pigment, or melanin, is produced.
Most people lose about 50 to 100 head hairs a day. These hairs are replaced — they grow back in the same follicle on your head. This amount of hair loss is totally normal and no cause for worry. If you're losing more than that, though, something might be wrong.

There are a number of reasons that could cause hair loss: an illness or surgery, hormonal problems, medicine, infection or an underlying disease. Once it is determined what is causing your hair loss then a course of treatment can take place.
The most common reason for hair loss in men is that it is inherited. This is referred to as “male-pattern baldness” which starts at an early age. There are different medicines and therapies to help treat hair loss but when these cannot help then a hair transplant could be considered a solution. Hairs are taken out of areas which still contain many hairs (usually at the back of the head, called donor area) and planted in the bald sections. In most cases hairs will grow in a normal way. So simple it sounds, a hair transplant is a highly sophisticated procedure where the right technology has to be chosen. Also it has to be considered that a hair transplant is not a cheap option to fight against the hair loss. So you should take your time to choose the best doctor to do the hair transplant. Anyhow it is the only option, which can really “cure” hair loss in just one day.

Eating a balanced, healthy diet is important for a lot of reasons, and it really benefits your hair.
If you're losing hair, some doctors recommend using baby shampoo, shampooing no more than once a day, and lathering gently. Don't rub your hair too vigorously with a towel, either. Many hair experts suggest you consider putting away the blow dryer and air drying your hair instead. If you can't live without your blow dryer, try using it on a low heat setting.
Style your hair when it's dry or damp. Styling your hair while it's wet can cause it to stretch and break. And try to avoid teasing your hair, which can cause damage. Finally, be careful when using chemicals — such as straighteners or color — on your hair, and avoid frequent use of chemical treatments.

About Allergy

An allergy is a reaction of your immune system to something that does not bother most other people.There are numerous substances that can become allergy-causing agents.The most common substances that often cause reactions are :
Pollen
Dust mites
Mold spores
Pet dander
Food
Insect stings
Medicines
Allergy symptoms are dependant upon the individual and can range from very mild, to extremely severe (anaphylactic). When an allergen enters the body of someone with a sensitized immune system, histamines are released into the blood by specialized cells.

Scientists think both genes and the environment have something to do with it. Normally, your immune system fights germs. It is your body's defense system. In most allergic reactions, however, it is responding to a false alarm.

Allergies can cause a runny nose, sneezing, itching,rashes,swelling or asthma.Although allergies can make you feel bad, they usually won't kill you. However, a severe reaction called anaphylaxis is life-threatening. If you want to buy alergy product click up in the main page(blue titles) to Allergies.

Ways to control Acne

Where acne comes?(causes)
Acne starts in the early teen years, when the oil glands in the body start making more sebum
In people who have acne, dead skin cells mix with the extra oil and plug up hair follicles in the skin. Bacteria that grows in the hair follicles causes more skin irritation.A "whitehead" occurs when the hair follicle is plugged with oil and skin cells. If the follicle is plugged near the surface of the skin and the air touches it, it turns black and is called a "blackhead." A blackhead isn't caused by dirt.If the wall of a plugged follicle breaks, the area swells and turns into a red bump. If the follicle wall breaks near the skin surface, the bump usually becomes a pimple. If the wall breaks deep in the skin, acne nodules or cysts can form. This is called "cystic acne."

Who gets acne?

Both boys and girls get acne. But it may be worse in boys because they have more skin oils.Heredity also plays a role. If your mother and father had bad acne, you may too. Your immune system plays a role too. Some people are extra sensitive to the bacteria that get trapped in their hair follicles.For many people, acne fades by the age of 25, but it can continue well into the adult years.
