Study links breast cancer risk to early-life diet and metabolic syndrome

Written By empapat on Senin, 17 September 2012 | 13.36

ScienceDaily (Sep. 17, 2012) — Striking new evidence suggesting that diet and related factors early in life can boost the risk for breast cancer -- totally independent of the body's production of the hormone estrogen -- has been uncovered by a team of researchers at the University of California, Davis.

The findings provide new insights into the processes that regulate normal breast development, which can impact the risk of developing breast cancer later in life. The study will be published Sept. 17 in the early edition of the Proceedings of the National Academy of Sciences.

"It's long been assumed that circulating estrogens from the ovaries, which underlie normal female reproductive development, were crucial for the onset of breast growth and development," said Russ Hovey, a UC Davis associate professor of animal science and senior author on the study.

"Our findings, however, suggest that diet and shifts in body metabolism that parallel changes seen during obesity and Type 2 diabetes can also stimulate breast growth entirely independent of estrogen's effects," he said.

The studies with mice used a diet supplemented with a form of the fatty acid known as 10, 12 conjugated linoleic acid or 10, 12 CLA, which mimics specific aspects of a broader metabolic syndrome.

In humans, this syndrome is linked to a broad array of changes associated with obesity that can increase the risk of Type 2 diabetes and cardiovascular disease.

The 10, 12 CLA was added to the diet of the test group of mice because it is known to disrupt normal metabolic processes. In this study, the supplement stimulated the mammary ducts to grow, despite the fact that the mice lacked estrogen.

The researchers demonstrated that the diet-induced breast development also increased the formation of mammary tumors in some of the mice.

They ruled out a role for estrogen as the possible cause for how diet increased growth of the breast tissues by giving the supplement to male mice and to female mice in which the function of estrogen was blocked.

The research team also discovered that various mouse strains responded differently to the dietary supplement despite similar metabolic changes, suggesting that there may be a genetic component for how diet and related metabolic changes affect breast cancer risk in different populations, Hovey said.

He noted that results from the study would likely have significant implications for better understanding human breast development before puberty and after menopause, when estrogens are less present.

"The findings of this study are particularly important when we superimpose them on data showing that girls are experiencing breast development at earlier ages, coincident with a growing epidemic of childhood obesity," Hovey said.

Adam Lock, an assistant professor of dairy cattle nutrition at Michigan State University, was co-principal investigator with Hovey on the original Dairy Management Inc. grant that supported studies leading to the PNAS publication.

"The biology of conjugated linoleic acid fatty acids has stimulated much scientific and public interest over the last two decades," said Lock. "These recent findings will further our understanding of the biology of this specific CLA isomer and also further advance our understanding of the role of bioactive fatty acids in health maintenance and disease prevention."

Other members of the research team are graduate students Grace Berryhill and Julia Gloviczki, Project Scientist Josephine Trott, postdoctoral researchers Lucila Aimo and Whitney Petrie, undergraduate student Carly Paul, and Professor Robert Cardiff, all of UC Davis; and Research Assistant Professor Jana Kraft of the University of Vermont.

The study was supported in part by Dairy Management Inc., the UC Davis Cancer Center and the Department of Defense.

Eating well during pregnancy reduces baby's obesity risk regardless of mom's size

ScienceDaily (Sep. 17, 2012) — If you are overweight and pregnant, your baby isn't destined to a life of obesity after all, according to a new research report published online in The FASEB Journal. In the report, a team of U.S. scientists show that modifying fat intake during pregnancy to a moderate level is enough to benefit the child regardless of the mother's size. Specifically, they found that a protein called "SIRT1" rewrites a developing fetus' histone code, which affects his or her "epigenetic likelihood" of being overweight or obese throughout his or her lifetime.

"We are finding that the cycle of obesity likely begins in the womb, however, we are also finding that obesity does not necessarily beget obesity," said Kjersti M. Aagaard, M.D., Ph.D., study author from the Division of Maternal-Fetal Medicine and the Department of Obstetrics and Gynecology at Baylor College of Medicine in Houston, Texas. "A diet laden with fat changes the molecular machinery which chemically modifies the structure of the developing infant's genetic material. These commonly called 'histone code' changes are rewritten-at least in part-by SIRT1, which in turn, alters key regulators of fat and glucose metabolism in the infant. It is our hope that these early steps will in turn break the cycle of obesity in the generations to come."

To make this discovery, Aagaard and colleagues used three groups of pregnant primates. The first group ate a healthy pregnancy diet (13 percent fat), while the second group ate a high fat diet (35 percent fat) and became obese. The third group was kept on a high fat diet for several years, became obese, and then was put on a healthy diet. Researchers were able to tease apart the effects on the infant of being exposed during pregnancy to a healthy diet versus an unhealthy high fat diet. The sirtuins and the proteins, and the genes regulating glucose and fat metabolism were analyzed. Results suggest that the livers of infants exposed to the high fat diet, showed less SIRT1 and less sirtuin activity than in the control group. However, infants exposed to a healthy pregnancy diet in both lean and obese groups had restored sirtuin. To prove that SIRT1 was specifically chemically modifying the histone code, scientists created a dead enzyme version. Using high level mass spectrometry, it was discovered that while the live enzyme version of SIRT1 was very good at chemically modifying histone proteins (specifically "deacetylating" histone protein H3) the dead version was not.

"What this study shows once again is that eating a healthy diet while pregnant holds true, regardless of your size or shape," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "Even if a woman isn't eating well before pregnancy, adopting good eating habits during pregnancy is still very good for the child and for her. This new report shows how diet affects offspring at the molecular level and points to new treatments for overweight people who were not fortunate enough to have mothers who ate well during pregnancy."

Adequate sleep helps weight loss

ScienceDaily (Sep. 17, 2012) — Adequate sleep is an important part of a weight loss plan and should be added to the recommended mix of diet and exercise, states a commentary in CMAJ (Canadian Medical Association Journal).

Although calorie restriction and increased physical activity are recommended for weight loss, there is significant evidence that inadequate sleep is contributing to obesity. Lack of sleep increases the stimulus to consume more food and increases appetite-regulating hormones.

"The solution [to weight loss] is not as simple as 'eat less, move more, sleep more,'" write Drs. Jean-Phillippe Chaput, Children's Hospital of Eastern Ontario Research Institute, Ottawa, Ontario and Angelo Tremblay, Laval University, Québec, Quebec. "However, an accumulating body of evidence suggests that sleeping habits should not be overlooked when prescribing a weight-reduction program to a patient with obesity. Sleep should be included as part of the lifestyle package that traditionally has focused on diet and physical activity."

The authors' recently published research found that total sleep time and quality of sleep predicted the loss of fat in people enrolled in a weight loss program.

The Canadian Obesity Network has included adequate sleep in its new set of obesity management tools for physicians.

About half of adults say schools should take action when kids bully with social isolation

ScienceDaily (Sep. 17, 2012) — U.S. adults repeatedly rate bullying as a major health problem for U.S. children. But a new poll from the University of Michigan shows adults have different views about what bullying behaviors should prompt schools to take action.

The University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health recently asked a nationwide sample of adults what behaviors should be considered bullying and what behaviors should spur school officials to intervene.

The vast majority of adults (95 percent) say schools should take action if a student makes another student afraid for his/her physical safety. Eighty-one percent said schools should intervene when someone humiliates or embarrasses another student and 76 percent call for intervention when someone spreads rumors.

But only 56 percent said isolating a student socially should prompt school intervention.

"The key finding from this poll is that adults don't see behaviors across the bullying spectrum as equivalent," says Matthew M. Davis M.D., M.A.P.P., director of the C.S. Mott Children's Hospital National Poll on Children's Health.

"This is concerning because isolating a student socially is considered to be a form of bullying, and a dangerous one," says Davis, associate professor of pediatrics and internal medicine at the U-M Medical School and associate professor of public policy at the Gerald R. Ford School of Public Policy.

"Isolating a student socially may be linked to episodes of school violence and also teen suicide."

Since year 2000, 46 states have passed laws related to bullying and 45 of them require schools to have bullying policies. But not all states have the same definition of what constitutes bullying, and the poll indicates that adults don't agree on this either.

In the poll, nearly all adults (90 percent) say threatening another student's physical safety is bullying and 62 percent also say embarrassing or humiliating a student is definitely bullying.

But just 59 percent say spreading rumors about a student is bullying and only 48 percent say isolating a student socially should be considered bullying.

Since the shooting at Columbine High School in 1999, and with subsequent school shootings and teen suicides linked to bullying, public concern about bullying has grown considerably in the U.S. In the last several years of the Poll's 'Top 10' list of greatest child health concerns, bullying has been rated by the public as a major problem for kids. The latest national data from the Youth Risk Behavior Survey in 2011, reported by the national Centers for Disease Control and Prevention, indicate that 20% of high school students report that they have been the victims of bullying.

"As school starts, this is the perfect time of year to have conversations about how each school can find solutions to the problems of bullying and address this important childhood health problem," says Davis.

Sex matters: Men recognize cars and women recognize living things best, psychological analysis finds

ScienceDaily (Sep. 17, 2012) — Women are better than men at recognizing living things and men are better than women at recognizing vehicles.

That is the unanticipated result of an analysis Vanderbilt psychologists performed on data from a series of visual recognition tasks collected in the process of developing a new standard test for expertise in object recognition.

"These results aren't definitive, but they are consistent with the following story," said Gauthier. "Everyone is born with a general ability to recognize objects and the capability to get really good at it. Nearly everyone becomes expert at recognizing faces, because of their importance for social interactions. Most people also develop expertise for recognizing other types of objects due to their jobs, hobbies or interests. Our culture influences which categories we become interested in, which explains the differences between men and women."

The results were published online on Aug. 3 in the Vision Research journal in an article titled, "The Vanderbilt Expertise Test Reveals Domain-General and Domain-Specific Sex Effects in Object Recognition."

"Our motivation was to assess the role that expertise plays in object recognition with a new test that includes many different categories, so we weren't looking for this result," said Professor of Psychology Isabel Gauthier. She directs the lab where post-doctoral fellow Rankin McGugin conducted the study.

"This isn't the first time that sex differences have been found in perceptual tasks. For example, previous studies have shown that men have an advantage in mental rotation tasks. In fact, a recent study looking only at car recognition found that men were better than women but attributed this to the male advantage in mental rotation. Our finding that women are better than men at recognizing objects in other categories suggests that this explanation is incorrect."

Discovery of the sex effect in object recognition also casts doubt on several studies that claim an individual's ability to recognize faces is largely independent of his or her ability to recognize objects.

"Face recognition abilities are exciting to study because they have been found to have a clear genetic basis," said Gauthier, "and many studies conclude that abilities in face recognition are not predicted by abilities in object recognition. But this is usually based on comparing faces to only one object category for men and women."

It took the multi-category analysis to reveal that face recognition abilities are correlated to the ability to recognize different object categories for men and women. For example, men who are better at recognizing vehicles also tend to be better at recognizing faces, while women who are better at recognizing living things tend to be better at recognizing faces.

The researchers modeled their new test after the well-established Cambridge Face Memory Task, which effectively measures a person's ability to recognize faces. After familiarizing themselves with a number of images, participants are shown three images at a time -- one from the study group and two that they haven't seen before -- and then are asked to pick out the image that they had studied.

While one goal of the new study was to compare object and face recognition skills, another goal was to develop a better way to measure who has exceptional skills in one domain: how to find the experts in the recognition of cars or birds or even mushrooms. To do this, the Vanderbilt researchers reasoned that performance on any category of interest needed to be compared to performance on many other categories, to ensure that the self-proclaimed bird expert is not only better with birds than most people, but also better with birds than with most other categories. So they designed the new test with eight categories of visually similar objects: leaves, owls, butterflies, wading birds, mushrooms, cars, planes and motorcycles.

To evaluate the new test, they administered it to 227 subjects -- 75 male and 82 female -- with a mean age of 23. When the results of the entire group were analyzed, the researchers found that increasing the number of categories revealed a large sex difference: Women proved significantly better at recognizing living things while men were better at recognizing vehicles. In addition, the researchers administered a face recognition test to about half of the participants, which allowed them to determine the correlation between vehicle recognition and face recognition in men and the correlation between recognition of living things and faces in women.

Vanderbilt post-doctoral fellow Jennifer Richler as well as Grit Herzmann, a post-doctoral fellow at the University of Colorado, Boulder and Research Assistant Magen Speegle also contributed to the study.

The research was supported by the National Eye Institute grants EYO13441-06A2 and P30-EY008126 and by the National Science Foundation's Temporal Dynamics of Learning Center grant SBE-0542013.

Your body doesn't lie: People ignore political ads of candidates they oppose

ScienceDaily (Sep. 17, 2012) — A recent study examined people's bodily responses while watching presidential campaign ads -- and discovered another way that people avoid political information that challenges their beliefs.

In the last days of the 2008 campaign, researchers had people watch a variety of actual ads for Republican presidential candidate John McCain and his Democratic rival Barack Obama while the viewers' heart rates, skin conductance and activation of facial muscles were monitored.

The results showed that partisan participants reacted strongly to ads featuring their favored candidate, but barely responded to ads featuring the rival candidate.

In comparison, people who didn't favor one candidate over the other showed similar physiological response patterns and intensity to ads for both Obama and McCain.

This suggests that partisan participants weren't really paying attention to the ads featuring the candidate they opposed even as they watched them, said Zheng Wang, lead author of the study and assistant professor of communication at Ohio State University.

"If people are exposed to information in ads regarding a candidate they oppose, they respond by basically tuning out," Wang said.

"A lot of research has shown that, behaviorally, we tend to selectively expose ourselves to information that reinforces our existing opinions. But this study further suggests that even when exposed to information, our attention to what is presented is highly selective, as well," she said.

Wang co-authored the study with Alyssa Morey, a graduate student in communication at Ohio State, and Jatin Srivastava, an assistant professor at Ohio University. Their results appear in a recent issue of the journal Communication Research.

The study involved 15 college students who came to Wang's laboratory in October 2008. They were hooked up with electrodes that measured four physiological responses: heart rate, skin conductance (a way to measure sweating, which is related to how stimulated and alert the person is), and muscle movements around the cheekbone and around the eyebrows.

Research has shown that these physiological responses, taken together, indicate emotional responses and attention levels, Wang said.

While hooked up to the electrodes, each participant watched 12 campaign ads -- six for Obama and six for McCain -- while their physiological reactions were recorded.

After watching the ads, the students filled out measures of how positively and negatively they regarded Obama and McCain in general.

The physiological measures used in the study revealed how much the viewers were paying attention and how they were reacting emotionally to ad content that was positive, negative, more emotionally arousing and less emotionally arousing.

For example, a lower heart rate suggests that the viewer is taking in information and paying more attention to the ad, while a higher heart rate suggests the viewer is not focused on the ads. The muscles in the face also indicate how much attentional effort a person is making.

In one key analysis of the study, the researchers used what they called a dynamical feedback model to see how the different ad factors interacted with the viewers' partisan leanings to influence their physiological reactions over time.

"At any one time, ad viewers' reactions are affected not just by what they are seeing at that exact moment, but also by what came before in the ad," Wang said. "The dynamical feedback model puts it all together to see how people react in a real-time, real-world way."

For supporters of a particular candidate, the feedback model suggests that the positive feelings that viewers have are amplified as they watch an ad for their candidate, Wang said. But for opponents, the feedback effects actually seem to decrease their response over time as they watch the ad -- in essence, they tune out, she said.

"When we integrate all of the ad message inputs into this dynamical system of the viewer's mind, we find the response of supporters is intensified, while the opponents become nonresponsive," she said.

The results also suggest that it isn't easy to predict how simple ad categories -- such as positive ads versus negative ones -- will affect viewers.

"The ad message is only part of the story because it interacts with how individuals process the ad," she said.

"In addition, one negative ad is very different from another negative ad, in terms of their content dynamics and how people react over time. And a 60-second version of an ad can have quite different effects from a 30-second version of the same ad. How people react to ads is a very complex and dynamic process."

The study was partially supported by a grant from the National Science Foundation.

Behavior issues are a bigger headache for children with migraines, research reveals

ScienceDaily (Sep. 17, 2012) — Kids who get migraine headaches are much more likely than other children to also have behavioral difficulties, including social and attention issues, and anxiety and depression. The more frequent the headaches, the greater the effect, according to research out now in the journal Cephalagia, published by SAGE.

Marco Arruda, director of the Glia Institute in São Paulo, Brazil, together with Marcelo Bigal of the Albert Einstein College of Medicine in New York studied 1,856 Brazilian children aged 5 to 11. The authors say that this is the first large, community based study of its kind to look at how children's behavioural and emotional symptoms correlate with migraine and tension-type headaches (TTH), and to incorporate data on headache frequency.

Children with or suffering from migraine had a much greater overall likelihood of abnormal behavioral scores than controls, especially in somatic, anxiety-depressive, social, attention, and internalizing domains. Children with TTH were affected in the same domains as migraine sufferers, but to a lesser degree.

The study used internationally validated headache questionnaires as well as the Child Behavior Checklist (CBCL) to assess emotional symptoms. The researchers trained school teachers in how to walk parents through questionnaires step by step.

For children with either migraine (23%) or TTH (29%), more frequent headaches correlated with increasingly abnormal scores on the behavior scale. The types of behavior most often seen were those characterized as internalizing -- behaviors directed towards the self. While less than a fifth of controls (19% of sample) have issues with internalizing behaviors, over half of migraine sufferers were affected. Externalizing behaviors, such as becoming more aggressive or breaking rules, were no more likely among the children with frequent attacks of headache than among the controls. The researchers suggested the CBCL may be underpowered to investigate the correlation between attention/hyperactivity and headaches in detail.

"As previously reported by others, we found that migraine was associated with social problems," said Arruda. "The 'social' domain identifies difficulties in social engagement as well as infantilized behavior for the age and this may be associated with important impact on the personal and social life."

"Providers should be aware of this possibility in children with migraines, in order to properly address the problem," he added.

Previous research has pointed to children with migraine being more likely than their peers to have other physical or psychological issues, including anxiety, depression, and attention and hyperactivity problems. But until now, few studies have examined the contrasts between TTH in children. Including headache frequency was also a missing part of the puzzle, the authors say.

Children often suffer from headaches, with migraine prevalence ranging from just over three percent to over one fifth of children as they progress from early childhood through to adolescence.

Only children are significantly more likely to be overweight, European study finds

ScienceDaily (Sep. 17, 2012) — Children who grow up without siblings have a more than 50 percent higher risk of being overweight or obese than children with siblings. This is the finding of a study of 12,700 children in eight European countries, including Sweden, published in Nutrition and Diabetes.

The University of Gothenburg, Sweden, was one of the participating universities in the study.

The study was conducted under the framework of the European research project Identification and prevention of Dietary and lifestyle-induced health EFfects In Children and infantS (IDEFICS), where researchers from various parts of Europe study diet, lifestyle and obesity and their health effects on children aged 2 to 9 years.

The study shows that only children have a more than 50 percent higher risk of obesity compared to their peers with siblings. The results were controlled for other influential factors, such as gender, birth weight and parental weight.

In the study, the children's measured BMI was linked to a parental questionnaire that included questions relating to the children's eating habits, television viewing habits and amount of outdoor play time.

"Our study shows that only children play outside less often, live in households with lower levels of education more often, and are more likely to have televisions in their bedrooms. But even when we take these factors into account, the correlation between singleton status and overweight is strong. Being an only child appears to be a risk factor for overweight independent of the factors we thought might explain the difference," says Monica Hunsberger, a researcher at the Sahlgrenska Academy, University of Gothenburg, who contributed to the study.

"The fact that only children are more susceptible to obesity may be due to differences in individual family environment and family structure that we were not able to measure in sufficient detail. To better understand the causality, a follow-up study of these families will start next year," says Lauren Lissner, a researcher at the Sahlgrenska Academy, University of Gothenburg.

Over 22 million children in Europe are estimated to be overweight. The study shows that obesity among children in general is three times more common in southern countries such as Italy, Spain and Cyprus than in Sweden and other northern countries.

Healthy outlook leads to a healthy lifestyle, study suggests

ScienceDaily (Sep. 13, 2012) — A 'can do' attitude is the key to a healthy lifestyle, University of Melbourne economists have determined.

Researchers from the Melbourne Institute of Applied Economic and Social Research analysed data on the diet, exercise and personality type of more than 7000 people.

The study found those who believe their life can be changed by their own actions ate healthier food, exercised more, smoked less and avoided binge drinking.

Professor Deborah Cobb-Clark, Director of the Melbourne Institute of Applied Economic and Social Research, said those who have a greater faith in 'luck' or 'fate' are more likely to live an unhealthy life.

"Our research shows a direct link between the type of personality a person has and a healthy lifestyle," she said.

Professor Cobb-Clark hoped the study would help inform public health policies on conditions such as obesity.

"The main policy response to the obesity epidemic has been the provision of better information, but information alone is insufficient to change people's eating habits," she said.

"Understanding the psychological underpinning of a person's eating patterns and exercise habits is central to understanding obesity."

The study also found men and women hold different views on the benefits of a healthy lifestyle.

Men wanted physical results from their healthy choices, while women were more receptive to the everyday enjoyment of leading a healthy lifestyle.

Professor Cobb-Clarke said the research demonstrated the need for more targeted policy responses.

"What works well for women may not work well for men," she said.

"Gender specific policy initiatives which respond to these objectives may be particularly helpful in promoting healthy lifestyles."

The study used data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey.

Mendapatkan Backlink Dengan Mudah

Written By empapat on Rabu, 27 Juni 2012 | 10.10

Cara Cepat Menaikkan Pagerank adalah dengan copy paste artikel ini dari atas sampai bawah. Tapi sebelum itu bacalah dulu pesan-pesan dibawah ini.

Silahkan pelajari dengan baik lalu anda terapkan dengan benar…. Ada kata bijak yang mengatakan "Honesty is The Best Policy (Kejujuran adalah politik/strategi terbaik)", mari kita buktikan….apakah konsep kejujuran disini dapat kita gunakan untuk menghasilkan traffic dan popularity yang sangat hebat dari sebuah metode rumit para expert webmaster atau pakar SEO..? Saya percaya kita bisa asal metode ini anda terapkan dengan benar…apabila ini di aplikasikan pada web/blog anda sesuai ketentuan maka:
  • Blog anda akan kebanjiran traffic pengunjung secara luar biasa hari demi hari, tanpa anda harus repot-repot memikirkan SEO atau capek-capek melakukan promosi keberbagai tempat di dunia online.
  • Blog anda juga akan kebanjiran backlink secara signifikan hari demi hari, tanpa perlu repot-repot berburu link keberbagai tempat di dunia internet.
Hal yang harus anda lakukan adalah ikuti langkah-langkah berikut :
  1. Buatlah postingan artikel seperti posting saya ini, atau copy-paste artikel ini. Lalu beri Judul sesuka anda (karena itu merupakan SEO buat web/blog anda sendiri).
  2. Anda cukup hanya meletakkan Link-Link di bawah ini pada artikel anda tersebut pada blog/web anda.

  •  
    1. viruses
    2. healthy heart
    3. Mate of God
    4. Domestic problems
    5. Racing Sport
    6. Dani Pedrosa
    7. Promo Tour
    8. Travel Safe
    9. Healthy Food
    10. Healthy Skin

  • PERATURAN :
    1. Sebelum anda meletakkan Link-Link tersebut ditas ke dalam postingan web/blog anda, harap hapus Link nomor 1 , Sehingga link no 1 hilang dari daftar link dan setiap link anda naikkan 1 level ke atas. Yang tadinya no 2 naik menjadi no 1, yang tadinya no 3 menjadi no 2, yang tadinya no 4 menjadi no 3 dan begitu seterusnya. Setelah itu masukkan Link anda pada urutan Paling bawah ( no 15 ).
    2. Ingat!!! Jangan Merubah Urutan daftar link.. Buktikan kejujuran anda.. Karena ini demi keuntungan bersama, kita sesama blogger 
    3. Apabila setiap blogger yang ikut dalam metode ini berhasil di duplikasi ole hblogger lain yang akan bergabung, andaikan 5 blogger yang bergabung maka Backlink yang anda dapat adalah Ketika:
    Posisi anda 15, jumlah backlink = 1
    Posisi 14, jumlah backlink = 5
    Posisi 13, jumlah backlink = 25
    Posisi 12, jumlah backlink = 125
    Posisi 11, jumlah backlink = 625
    Posisi 10, jumlah backlink = 3.125
    Posisi 9, jumlah backlink = 15.625
    Posisi 8, jumlah backlink = 78.125
    Posisi 7, jumlah backlink = 390.625
    Posisi 6, jumlah backlink = 1.953.125
    Posisi 5, jumlah backlink = 9.765.625
    Posisi 4, jumlah backlink = 48.828.125
    Posisi 3, jumlah backlink = 244.140.625
    Posisi 2, jumlah backlink = 1.220.703.125
    Posisi 1, jumlah backlink = 6.103.515.625
    Dan semua Dari kata kunci yang anda inginkan, bayangkan jika ini bisa berjalan dengan sempurna maka anda akan memperoleh 6.103.515.625 external link yang berasal dari berbagai blog yang anda tidak akan pernah bayangkan sebelumnya. Belum lagi apabila ada pengunjung blog anda dari Link List tersebut diatas maka otomatis anda akan memperoleh traffic ke web/blog anda juga. Ingat!!! Aturuan mainnya, Anda harus memulai dari urutan paling bawah (no 15) sehingga hasil backlink anda bisa Maksimal. Jangan salahkan saya apabila anda tidak mengikuti metode ini dengan benar dan Link anda tiba-tiba berada pada urutan no 1 dan menghilang pada Link daftar. Jadi mulai lah pada urutan paling bawah(no 15). Bisakah Anda melakukan tindakan tidak fair atau tidak jujur dengan menyabotase metode ini, misalkan saja "menghilangkan semua link asal" lalu di isi dengan link web/blog anda sendiri…? ….Bisa, dan metode ini menjadi tidak maksimal. Kejujuran adalah strategi/politik terbaik…..Tapi saya yakin bahwa kita semua tak ingin menjatuhkan kredibilitas diri sendiri dengan melakukan tindakan murahan seperti itu… —- SELESAI —-
    Semoga metode ini bisa berjalan sesuai harapan kita bersama. . . ! ! !
    Cara Cepat Menaikkan Pagerank mudah bukan? Beri tahu kepada kawan2 blogger yang lain agar pagerank anda naik, naik, dan terus naik.. << Kebenaran selalu ada satu
