Will Stem Cells Transform Plastic Surgery

Silicone breast implants and Botox could one day be things of the past thanks to promising new techniques that would allow doctors to work plastic-surgery miracles using only a patient's own stem cells.Traditionally, plastic and reconstructive surgery has relied heavily on fillers. Bags full of saline or silicone are used to plump up breasts. Chunks of fat are taken from one area of the body and grafted into another.These techniques, which like other body enhancement procedures have soared in popularity in recent years, can work successfully but they also have drawbacks.Dr. J. Peter Rubin, assistant professor of plastic and reconstructive surgery at the University of Pittsburgh School of Medicine, said using fillers requires invasive surgery and the results may not look ideally natural.Related In the case of fat grafts, they also might not last as long as a patient would like, as fat transferred whole to a new part of the body has a tendency to break down as time goes on.Replacing these fillers with stem cells could solve the problems.Stem cell magicStem cells are cells that have the ability to make more of themselves and to differentiate into special types of cells, like skin or other tissue types.Some stem cells, called pluripotent or multipotent, are capable of turning into many different kinds of cells and growing wide varieties of tissues, ranging from bone to neurons to organs and muscle.While embryonic stem cells are the most well-known type (and the type that raises controversy), not all pluri- and multi-potent cells come from embryos.Certain so-called adult stem cells, which we make in our bodies, also have these abilities and would most likely be the cells used in plastic surgery."If we can capitalize on stem-cell biology, we can use those cells to reconstruct lost tissue or construct new tissue in a less invasive way," Rubin said.In order to do this, he said, researchers would separate out multi- or pluripotent adult stem cells and grow them in a petri dish.Depending on how they're grown and what materials they're grown in, the stem cells can be coaxed into taking on different specialties, such as fat or cartilage.Those cells would then be injected into the patient, where they would continue to grow and divide, creating a small amount of natural tissue. No surgery required.According to Rubin and colleagues, these techniques could one day be used to fill out wrinkles on an aging face, replace breast tissue lost to cancer treatment, or even grow a natural breast implant.Fat chanceWhile these applications are still a ways out, plastic surgeons in Europe and Asia are already using stem cells to get better results for their patients. To do this, they're harvesting stem cells from an unlikely place — human fat.It turns out that fat is an ample source of multi- and pluripotent stem cells. Science has known for decades that fat tissue is home to a large population of immature cells that have the ability to grow into new fat cells.Rubin said that around 2000 and 2001, researchers began to realize that these "pre-fat cells" were actually stem cells that could become not just fat, but cartilage, bone and even neurons and heart muscle.Unlike other tissues rich in stem cells, such as bone marrow, fat tissue is easy to extract. All you need is liposuction.Today, as part of ongoing clinical trials and regular practice, doctors outside the United States are taking stem cells from liposuctioned fat and using them to make traditional fat grafts more effective.Tom Baker, director of investor relations for Cytori, a San Diego-based company that makes machines for processing fat stem cells in the operating room, described how it works.First, a doctor liposuctions fat from a patient. Half that fat gets set aside, while the other half is processed to pull out a mixture of cells rich in stem cells.That mixture is then injected back into the reserved fat, which is grafted into place inside the patient.The result is a fat graft supercharged with stem cells.Healthier cellsA Japanese study and a Cytori-funded study presented at the San Antonio Breast Cancer Symposium in December 2007 have shown that the supercharged grafts, unlike normal fat grafts, maintain a more natural shape and don't wither away.The difference is extremely important to patients. The Japanese study, for instance, was conducted on women who'd lost part of a breast to cancer and wanted the reconstructive surgery to look as normal as possible.Supercharged fat grafts work because stem cells do more than just grow new cells, said Rubin's colleague Dr. Keith March, a professor of medicine, cellular and integrative physiology and biomedical engineering at the Indiana University School of Medicine. They also support cells and tissues, making them healthier."It's just like the trunk of a tree," March said. "It gives rise to branches and roots, but it's also involved in providing the nutrient supply. Stem cells are involved in maintaining and repairing the tissues around them."Copyright © 2008 Imaginova Corp. All Rights Reserved.

Google Ranking Secrets

behind Google ranking
via The Official Google Blog by Karen on 7/16/08

In my previous post, I introduced the philosophies behind Google ranking. As part of our effort to discuss search quality, I want to tell you more about the technologies behind our ranking. The core technology in our ranking system comes from the academic field of Information Retrieval (IR). The IR community has studied search for almost 50 years. It uses statistical signals of word salience, like word frequency, to rank pages. (See "Modern Information Retrieval: A Brief Overview" for a quick overview of IR technology.) IR gave us a solid foundation, and we have built a tremendous system on top using links, page structure, and many other such innovations.

Search in the last decade has moved from give me what I said to give me what I want. User expectations from search have rightly increased. We work hard to fulfill the expectations of each and every user, and to do that we need to better understand the pages, the queries, and our users. Over the last decade we have pushed the technologies for understanding these three components (of the search process) to completely new dimensions.

When we talk about queries at Google, we use square brackets [ ] to mark the beginning and end of queries (see "How to write queries" by Matt Cutts), a notation I will use throughout this post. (Pages and search results change frequently, so in time, some examples used here may not behave as explained.)

Understanding pages: Over years we have invested heavily in our crawl and indexing system. As a result we have a very large and very fresh index. In addition to size and freshness, we have improved our index in other ways. One of the key technologies we have developed to understand pages is associating important concepts to a page even when they are not obvious on the page. We find the official homepage for Sprovieri Gallery in London for the Italian query [galleria sprovieri londra], even though the official page does not have either London or Londra on it. In the U.S., a user searching for [cool tech pc vancouver, wa] finds the homepage www.cooltechpc.com even though the page does not mention anywhere that they are in Vancouver, WA. Other technologies we have developed include distinctions between important and less important words in the page and the freshness of the information on the page.

Understanding queries: It is critical that we understand what our users are looking for (beyond just the few words in their query). We have made several notable advances in this area including a best-in-class spelling suggestion system, an advanced synonyms system, and a very strong concept analysis system.
Most users have used our spelling suggestion system at one time or another. It knows that someone searching for [kofee annan] is really searching for Mr. Kofi Annan, and is prompted: Did you mean: kofi annan; whereas someone searching for [kofee beans] is actually looking for coffee beans. Doing this internationally with very high accuracy is hard, and we do it well.



Synonyms are the foundation of our query understanding work. This is one of the hardest problems we are solving at Google. Though sometimes obvious to humans, it is an unsolved problem in automatic language processing. As a user, I don't want to think too much about what words I should use in my queries. Often I don't even know what the right words are. This is where our synonyms system comes into action. Our synonyms system can do sophisticated query modifications, e.g., it knows that the word 'Dr' in the query [Dr Zhivago] stands for Doctor whereas in [Rodeo Dr] it means Drive. A user looking for [back bumper repair] gets results about rear bumper repair. For [Ramstein ab], we automatically look for Ramstein Air Base; for the query query [b&b ab] we search for Bed and Breakfasts in Alberta, Canada. We have developed this level of query understanding for almost one hundred different languages, which is what I am truly proud of.



Another technology we use in our ranking system is concept identification. Identifying critical concepts in the query allows us to return much more relevant results. For example, our algorithms understand that in the query [new york times square church] the user is looking for the well-known church in Times Square and not for articles from the New York Times. We don't just stop at identifying concepts; we further enhance the query with the right concepts when, for instance, someone looking for [PC and its impact on people] is in fact looking for impact of computers on society, or someone who searches for [rainforest instructional activities for vocabulary] is really looking for rain forest lesson plans. Our query analysis algorithms have many such state-of-the-art techniques built into them, and once again, we do this internationally in almost every language we serve.

Understanding users: Our work on interpreting user intent is aimed at returning results people really want, not just what they said in their query. This work starts with a world class localization system, and adds to it our advanced personalization technology, and several other great strides we have made in interpreting user intent, e.g. Universal Search.

Our clear focus on "best locally relevant results served globally" is reflected in our work on localization. The same query typed in multiple countries may deserve completely different results. A user looking for [bank] in the US should get American banks, whereas a user in the UK is either looking for the Bank Fashion line or for British financial institutions. The results for this query should return local financial institutions in other English speaking countries like Australia, Canada, New Zealand, South Africa. The fun really starts when this query is typed in non-English-speaking countries like Egypt, Israel, Japan, Russia, Saudi Arabia, Switzerland. Likewise the query [football] refers to entirely different sports in Australia, the UK, and the US. These examples mostly show how we get the localized version of the same concept correctly (financial institution, sport, etc.). However, the same query can mean entirely different things in different countries. For example, [Côte d'Or] is a geographic region in France - but it is a large chocolate manufacturer in neighboring French-speaking Belgium; and yes, we get that right too :-).



Personalization is another strong feature in our search system which tailors search results to individual users. Users who are logged-in while searching and have signed up for Web History get results that are more relevant for them than the general Google results. For example, someone who does a lot football-related searches might get more football related results for [giants], while other users might get results related to the baseball team. Similarly, if you tend to prefer results from a particular shopping site, you will be more likely to get results from that site when you search for products. Our evaluation shows that users who get personalized results find them to be more relevant than non-personalized results.



Another case of user intent can be observed for the query [chevrolet magnum]. Magnum is actually made by Dodge and not Chevrolet. So we present the results for Dodge Magnum with the prompt See results for: dodge magnum in our result set.



Our work on Universal Search is another example of how we interpret user intent to give them what they (sometimes) really want. Someone searching for [bangalore] not only gets the important web pages, they also get a map, a video showing street life, traffic, etc. in Bangalore -- watching this video I almost feel I am there :-) -- and at the time of writing there is relevant news and relevant blogs about Bangalore.
Finally let me briefly mention the latest advance we have made in search: Cross Language Information Retrieval (CLIR). CLIR allows users to first discover information that is not in their language, and then using Google's translation technology, we make this information accessible. I call this advance: give me what I want in any language. A user looking for Tony Blair's biography in Russia who types the query in Russian [Тони Блэр биография] is prompted at the bottom of our results to search the English web with:

Similarly a user searching for Disney movie songs in Egypt with the query [أغاني أفلام ديزني] is prompted to search the English web. We are very excited about CLIR as it truly brings us closer to our mission to organize the world's information and make it universally accessible and useful.

I could go on and on showing examples of state-of-the-art technology that we have developed to make our ranking system as good as it is, but the fact is that search is nowhere close to being a solved problem. Many queries still don't get satisfactory results from Google, and each such query is an opportunity to improve our ranking system. I am confident that with numerous techniques under development in our group, we will make large improvements to our ranking algorithms in the near future.
I hope my two posts about Google ranking have made it clear that we live and breathe search, and we are more passionate than ever about it. Our fervor for serving all our users worldwide is unprecedented. We pride ourselves in running a very good ranking system, and are working incredibly hard every day to make it even better.

Top 10 Reasons to Eat Breakfast

It's often said that breakfast is the most important meal of the day. Find out why it's so important to get off to a good start. By Katelyn Dieffenderfer,Quality Health News When youÂ’re hitting the snooze button for the third time, breakfast is probably one of the last things on your mind. After all, you still have to shower and then race to work in time to make that presentation. But according to experts, letting a hectic schedule force you to skip breakfast could compromise your health. Breakfast Benefits The next time youÂ’re considering skipping the most important meal of the day, think about the following reasons to get back on track.

• Food that fuels. A healthy breakfast provides you with enough nutrients to energize your body for hours.

• Healthier eating habits. Studies have shown that people who eat breakfast consume more vitamins, minerals, and fiber, and less fat and cholesterol.

• Calorie cutting. People who don’t eat breakfast are likely to eat more calories throughout the day than people who skip lunch, according to the Nemours Foundation’s Center for Children’s Health and Media.

• Reduced diabetes risk. People who eat breakfast are significantly less likely to be diabetic than those who usually don’t, according to the American Heart Association.

• Weight control. A study by the National Weight Control Registry shows that eating breakfast actually helps keep people’s weight down.

• Increased focus. According to the American Dietetic Association, people who eat breakfast are better able to concentrate and be more productive throughout the morning.

• Enhanced memory. According to experts, eating breakfast improves memory and learning. In one study, college students who ate a morning meal scored 22 percent higher in a word-recall test than those who skipped breakfast.

• Better fitness. Researchers believe that people who eat breakfast have higher energy levels and may engage in more physical activity than people who don’t.

• Improved mood. Skipping breakfast can make you feel tired, irritable, or sad. Even grabbing some fresh fruit or a bowl of cereal can help boost your mood.

• Stress reduction. The time you spend eating breakfast can be relaxing and help you to mentally prepare for the day. Eating breakfast also forces you to slow down, helping you to prioritize. Keep in mind, however, that all breakfasts are not created equal—a healthy morning meal should be balanced and not too heavy. So, skip the eggs, bacon, sausage, and biscuits, and go for whole-grain cereals with fruit or juice instead. Or opt for an egg-white omelet filled with vegetables.

Dr. Greenberg has been featured in many magazines and on CBS, ABC, and NBC news programs as a specialist in liposuction, smart lipo and body sculpture.What Is Liposuction?Liposuction (lipoplasty) is a procedure that can help contour your body by removing unwanted fat and inches from certain parts of the body, including the abdomen, hips, buttocks, thighs, arms and chin. Liposuction is not a replacement for diet or exercise, but it helps selected patients get rid of stubborn areas that do not respond to other weight loss methods. With weight loss, the fat cells in your body only shrink - they do not disappear. Liposuction surgery actually removes the fat cells from your body. * Ultrasound assisted lipoplasty * The tumescent technique * Power assisted lipoplasty * Smart lipoDr. Greenberg utilizes a unique combination of tumescent liposuction, along with external ultrasound and power assisted liposuction. When used together, these methods provide the patient with a smoother contour and a quick recovery, with minimal pain or bruising. There will be a noticeable difference in your body contour almost immediately after liposuction surgery and a small amount of swelling that will continue to subside for a few months after. Your new contour will remain permanent as long as you maintain a healthy lifestyle. If you gain weight after your liposuction surgery, the weight will distribute itself evenly throughout your body and will not settle in the same problem areas.These methods provide the patient with a smoother contour and a quick recovery, with minimal pain or brusingWhat is Smart Lipo?Smart lipo is a procedure to remove fat cells from your body.
