Raman Heads For The Clinic

http://pubs.acs.org/cen/coverstory/88/8838cover.html

September 20, 2010: Raman has both strengths and weaknesses for medical applications. As a type of vibrational spectroscopy, it can take advantage of intrinsic molecular differences between various chemicals in the body to draw pictures that traditionally require the introduction of tags or stains. Thus it can eliminate the need for some sample preparation and can reduce the possibility of perturbing the system. However, the most traditional form of Raman—spontaneous Raman scattering—scatters only a tiny fraction of incident photons at a frequency different from the frequency of the incident light. The weakness of this effect means that Raman is not particularly sensitive..

One application that Raman is particularly suited to is bone analysis, such as that required to track the treatment of osteoporosis. The mineral components of bone produce strong, easily distinguishable Raman bands. Bone consists of mineral, primarily hydroxyapatite, over a protein matrix composed mainly of collagen. The Raman spectra reveal the quality of the bone tissue, and the spectra vary with a number of factors, including age, exercise, diet, mechanical loading, damage, and disease, says Michael D. Morris, a chemistry professor at the University of Michigan who has been studying bones with Raman for more than a decade

A related application of Raman is the detection of early dental caries, more commonly known as tooth decay



The Latest Laser Lipo Innovation: SmartLipo Triplex, 3 Wavelengths to Melt Fat and Tighten Skin

http://www.americanhealthandbeauty.com/articles/?article=2274

October 22, 2009: Cynosure, Inc. (Nasdaq: CYNO), an aesthetic laser manufacturer, introduced SmartLipo Triplex(TM), the first laser lipolysis technology that uses three wavelengths which are well absorbed by fat and allow for greater tissue tightening. SmartLipo Triplex will be launched at Plastic Surgery 2009, the American Society of Plastic Surgeons (ASPS) Annual Meeting, which starts this Friday in Seattle.SmartLipo Triplex adds a 1440 nm wavelength to the MPX generation of the laser. Through Cynosure's patented MultiPlex technology, the three wavelengths are combined in one laser output. Two wavelengths fire sequentially, liquefying the fat and tightening the skin with collagen stimulation.

This new generation of SmartLipo technology offers 20 times greater fat absorption than single wavelength lasers. Dr. Barry DiBernardo, Medical Director of New Jersey Plastic Surgery & MedNet Technologies, Inc. in Montclair, NJ, says "Combining the photomechanical effects of the 1440 nm with the 1064 nm wavelength results in even greater disruption of fatty tissue for faster and deeper treatments than the 1064 wavelength alone. At the same time, the Smartlipo Triplex continues to deliver unmatched tissue tightening through tissue coagulation by blending the 1064 and 1320 nm wavelengths."



Laser liposuction: No-surgery weight loss

http://www.txcn.com/sharedcontent/dws/news/localnews/tv/stories/wfaa091020_wz_laserlipo.2362e562f.html

October 20, 2009: A new low-level laser is on the market promising results in just two weeks without the downtime of surgery.A $2,400 Zerona treatment looks like a laser light show, but the ruby red beams are working to reduce fat in tissue under the skin.

The patient feels no heat. There's no incision, no downtime.So for two weeks (that's six visits), Cook spends 40 minutes under low-level lasers that are FDA-approved for laser-assisted liposuction.

Aqua Medical Spa laser technician Deborah Blumka uses the beams to customize treatments to the areas Cook wants to target.

Patients have to drink a lot of water during the two-week regimen while staying active and watching their diet. Otherwise, the treatment won't work.To date, there are no long-term studies to determine whether the laser treatments have any long-term side effects. But the treatment promises to break up unwanted fat, leading the body through the normal detoxification process.



New surgical technique uses laser energy to destroy brain tumors

http://www.kens5.com/news/health/stories/KENS20091007-BrainSurgery.1f3883350.html

October 7, 2009: For the first time in San Antonio, doctors used a new technique to kill a cancerous brain tumor. It's a novel approach using laser energy.

In an operating room at St. Luke's Baptist Hospital, the doctor secured an anchor in the outside of the skull. Then, using what's called neuro-navigation for precision, he slid a catheter several inches inside the head. That catheter houses a laser that can zap the cells growing out of control and threatening Perez' life.

"What's really nice about this technique is that the laser light being emitted from the tip of the diode is absorbed by the tumor cells,"

The device used for laser ablation of brain tumors has been FDA approved for about two years. San Antonio is one of fewer than 10 sites around the country offering this novel technique. It could help many people who have run out of other options.



Laser technology may soon be used for corneal transplants

http://www.channelnewsasia.com/stories/singaporelocalnews/view/1009238/1/.html

04 October 2009 SINGAPORE: In what could be a medical breakthrough in Singapore, corneal transplants may soon be carried out using laser technology instead of by hand.

You've probably heard of Lasik surgery to correct short-sightedness. That same technology could be used to perform corneal transplants.

Apart from preventing blindness through corneal transplant, doctors also want to get people off glasses, including those with presbyopia - a condition affecting older people who have problems reading fine print. The treatment involves inserting a tiny implant which sharpens vision through a pinhole effect. Patients will not be able to feel the implant in their eye nor will it block their vision, because it is only 3.8mm wide and just one-twentieth the thickness of human hair.



NO MORE D-D-DENTIST DRILL WITH REVOLUTIONARY NEW LASER

http://www.dailymail.co.uk/health/article-1217850/No-d-d-dentist-drill-revolutionary-new-laser.html

03rd October 2009 A laser that treats tooth decay using a painless beam of light is set to do away with the dental drill - as well as the anaesthetic injections needed to numb pain.

Lasers have been used in some areas of dentistry for a few years but they haven't been fast enough to replace the drill 'This has changed all that. Now a laser can be used to remove tooth decay and prepare cavities and crowns.'

The laser is gentle and precise, so no anaesthetic is needed. 'The laser is shone on to the tooth and there is a spray of water but no grinding,'

Lasers work by emitting high-speed pulsed light, and different frequency lasers will have different effects - some will burn through tissues, for example, while others will kill bacteria. 'You can use the laser to prepare a cavity and then clean a patient's gums,' The estimates show that laser treatment will cost about 15 per cent more than conventional dental work.

'It also offers the first permanent cure for sensitive teeth, by "sealing" the layer of exposed dentine that is the cause of tooth sensitivity.'



CAN LASERS STIMULATE A HAIR-GROWTH SPURT?

http://online.wsj.com/article/SB10001424052748704471504574441211355376166.html?mod=googlenews_wsj

SEPTEMBER 28, 2009 Losing your hair? Just glide a handheld laser over your scalp three times a week and you'll see a benefit, say the companies selling the products.

Many doctors are skeptical of claims made for the lasers, but a study found that one product did spur hair growth.

Hereditary hair loss is a medical condition that affects some 50 million American men, according to the American Academy of Dermatology. Medications, including the oral drug Propecia and the topical Rogaine, are often used to treat it. But the drugs don't work for everyone and can have side effects, according to dermatologists.

A number of companies sell handheld, low-intensity lasers for home use that are intended to stimulate hair follicles, typically three times a week for 10 to 15 minutes. The lasers, which aren't covered by insurance, are available online, at some doctors offices and at some retailers.

Scientists say that low-level lasers are safe and likely do act on cellular compounds that can spur hair growth. One major published study showed an average 7% increase in hair density with the HairMax after 26 weeks.



PROCEDURE USES LASER TO GET RID OF FAT

http://www.wcpo.com/news/local/story/Procedure-Uses-Laser-To-Get-Rid-Of-Fat/CakyeDiuk0GV-AEIQEf4ZQ.cspx

26 Sep 2009 : A doctor in Central Indiana is one of the first in the state to offer a laser treatment to get rid of fat. Doctor Randy Shoup is trained to use a Zerona laser. He aims the laser where the patient wants to lose fat. The laser puts a hole in fat cells, which leak, and the body's lymphatic system drains away the fat.

It takes six treatments in all, and costs several thousand dollars, but doctors say there is a big benefit for patients.

"No, there's no heat, there's no pain, there's no nothing, you can't feel anything," says Dr. Shoup.

The doctor says he's seen patients lose from three to nine inches. The FDA has approved the procedure.



Laser Treatment Offers Hope For Vitiligo Patients

http://wcbstv.com/topstories/vitiligo.laser.treatment.2.919425.html

: Jan 27, 2009-- NEW YORK (CBS) Imagine developing a condition where you start to lose the color in your skin. It's called "vitiligo" and it affects millions of people in this country. If you remember the King of Pop from his "Thriller" days, you might notice that his skin tone was what you would expect for an African-American. Today? Michael Jackson is as pale and milky white as a ghost. What happened is he developed the skin condition vitiligo.



HealthWatch: Radio Frequency Laser Resurfacing

http://wcbstv.com/seenat11/radio.frequency.laser.2.918406.html

: Jan 26, 2009-- Dr. Susan Tanne is an aesthetic physician using the Matrix RF for skin resurfacing. She says it costs her less to acquire and operate, patients need fewer treatments and this means everybody wins.

"It's tunable fractional resurfacing which means I can simulate the results of many different laser devices in one treatment by pressing a button," Dr. Tanne said. "A device that is using radio frequency, which means we're not using laser, it is safe. It is good for all skin types. It requires minimal down time."

And it targets sun damage, texture and wrinkles. The radio frequency penetrates the skin leaving a pattern of micro-sized dots -- sparing the skin from extensive damage -- but stimulating the growth of new collagen, improving texture and appearance.



Laser scalpel deployed in scar wars

http://www.capecodonline.com/apps/pbcs.dll/article?AID=/20080821/LIFE/808210308

August 21, 2008-- Andrew Sifflard refers to his hometown of Teaneck, N.J., as "sinus valley." Sifflard once blamed the area's abundance of allergy-causing pollen and dry winter air for his frequent nosebleeds. Sifflard, however, kept experiencing the problem after his move to Chatham in 1981. The nosebleeds even worsened during recent years. "It was getting to the point where I'd have trouble breathing," he says. "I wouldn't go anyplace without putting cotton balls in my pocket." Sifflard, 73, finally went to his family doctor, who noticed an abnormal mass in his left nostril. The doctor referred him to an ear, nose and throat specialist who diagnosed him with a benign glomus tumor - an extremely rare tumor fed by blood vessels.

Surgeons have been using CO2 lasers for decades because they allow more precise cutting than traditional scalpels. However, these lasers could transmit light only in a straight line to places surgeons could easily see, which limited their access. The lasers could not be used for surgeries that involved long, winding distances into the nose or certain parts of the throat

The BeamPath fiber got clearance from the Food and Drug Administration in 2006, for use in surgeries. "It's the world's most precise flexible scalpel," The laser fibers are manufactured in Cambridge by OmniGuide Inc., . The company reports that the scalpels have been used in more than 4,000 procedures to date. In Sifflard's case, the CO2 laser scalpel allowed Doctor to remove the entire tumor with just one operation. Without this tool, surgeons might have needed to destroy the blood supply feeding the tumor a few days before actually removing the tumor to prevent excessive bleeding,



Laser Technology Spots Cavities Before They Start

http://www.washingtonpost.com/wp-dyn/content/article/2008/08/22/AR2008082202436.html

: August 22, 2008 -- The technology, called "Raman spectroscopy" (RS), is not brand new. In fact, scientists in other fields have long been using it to distinguish between various chemicals, based on their unique molecular fingerprints.

"The technique we are working with can tell the difference between [healthy] enamel and decaying enamel, and so in the future, if this technology is further developed, a dentist could identify early decay using it," explained study co-author Frances Downey, a graduate student with the Biomaterials, Biomimetics & Biophotonics Research Group operating out of the Dental Institute of King's College London.

By focusing RS optical fibers on individual teeth, the authors were able to track the unique light patterns that emanate from chemical compositions on either healthy or decaying enamel.



Laser Reduces Wrinkles

http://www.ivanhoe.com/channels/p_channelstory.cfm?storyid=19275

: July 25, 2008 (Ivanhoe Newswire) -- Looking for a new way to reduce wrinkles? Carbon dioxide may be the answer. According to new research, a carbon dioxide laser can rejuvenate the skin. It vaporizes water molecules inside and outside of the cells, causing thermal damage to the surrounding tissue. The skin then produces more of the protein collagen, which fills in wrinkles.

A scale measuring facial wrinkles showed those who received the Carbon diaoxide laser improved by 45 percent. The results were consistent over all areas of the face. The study from the University of Michigan also showed 45 percent of patients had no complications following the procedure. Complications that did occur are mila (small, white cysts), acne, hyperpigmentation (darkening of the skin), hypopigmentation (lighting of the skin), infection or sagging of the eyelids. However, those who did experience complications averaged 2.3 years of follow-up, until problems resolved

"In addition to structural changes, the healing process frequently leads to pigmentary (coloring) changes," the study authors write. "These changes in the skin pigmentation may be desirable, such as when patients wish to remove solar evidence of aging; however, changes in pigmentation after treatment can often be a troubling adverse effect." From their findings, researchers say hypopigmentation was the only long-term adverse effect and those patients were more likely to have a greater response to treatment.



Laser Dentist Drill

http://www.photonics.com/content/news/2008/July/21/92542.aspx

: July 21, 2008 (LONDON, England) -- Raman spectroscopy is most commonly used to distinguish between different chemicals by identifying each molecule's unique fingerprint. In dentistry, this technology can be used to detect the first signs of decay simply and painlessly by pointing an optical fiber at the tooth to detect chemical changes within.

Researchers were able to tell healthy teeth from decaying teeth because light from the laser scatters differently due to bacteria. This new technology, which may be available in dental surgeries in five years from now, could greatly reduce the need for drilling and filling simply by way of early detection.

According to Dr. Frederic Festy, who is supervising the project, decaying teeth are currently uncovered either by visual examination or the use of x-rays, but usually by then, the damage has been done and the decayed area must be drilled out. However, Dr. Steven Hogg, a microbiologist at Newcastle University's dental school, confirms that it is possible to repair teeth with a special mouthwash or fluoride varnish if dental decay is caught early enough.



Tongue Cancer Laser

http://www.kimt.com/medical/17105381.html

: Chicago, IL - A patient with a hard to reach tumor inside their throat can be a challenging problem for a surgeon.

But a new laser technology makes removing these tumors easier for everyone.

This woman had a sore throat and acid indigestion before her tongue tumor was discovered

Traditionally, doctors would remove these hard-to-reach tumors with surgery through the patient's neck or jaw.

Now doctors can remove the tumors through the mouth, with a flexible fiber, that delivers CO2 or carbon dioxide laser energy.



Laser Brings Relief To Achy Backs

http://www.theindychannel.com/health/15735628/detail.html

March 28, 2008 : INDIANAPOLIS -- Amy Jones is an active mother of five who enjoys skiing, but back pain began keeping her off the slopes.

"I had pain that went down my leg and into my foot," Jones said.

Jones said she finally found relief when she was treated with Echronia, a cool or low-level laser that doctors say is an effective alternative to prescription drugs for back-pain treatment. The laser stimulates damaged cells through the skin. Dr. Steve Mangas is an Indianapolis chiropractor who offers the tool to patients.

"After tissue damage has occurred, the laser will accelerate the repair process by decreasing the amount of enzymes that cause swelling," Mangas said. "It improves the rate that the tissue heals."

He said this improves circulation to decrease pain and inflammation by 70 percent. Treatments take a few minutes and inflict no pain.

"You'll feel a gradual lessening of pressure and discomfort," Mangus said.

Within months of her Echronia treatment, Jones was able to enjoy her 20th anniversary in Hawaii without medication.



Femtosecond laser has dentistry applications

http://www.dentalplans.com/articles/31422/

March 20,2008 : A group of researchers at the University of Missouri has been developing what they call the UUL or ultra-fast, ultra-intense laser with possible uses in medical fields including dentistry, cancer treatments and joint implant surgeries.

The devices have a laser pulse that lasts one quadrillionth of a second, also called a femtosecond, which enables the laser to focus its point on its target at such a precise speed and level of efficiency that surrounding areas are not affected.

In dentistry, the laser could treat tooth decay without compromising the tooth's structure and provide a much more efficient and harmless method of treatment for patients.

According to Robert Tzou, James C. Dowell professor and chairman of the institution's department of Mechanical and Aerospace Engineering, the laser is capable of destroying targets as small as cancer cells without injury to surrounding cells, with special relevance to cancer treatment patients who could hopefully experience no side effects or down time after treatment.



YAG laser dental procedure considered 'effective' in treating gum disease

http://www.dentalplans.com/articles/31429/

March 20, 2008 : The Laser Assisted New Attachment Procedure (LANAP) from Millennium Dental Technologies has been proven an effective treatment of moderate to severe gum disease, including gingivitis and periondontitis in a peer-reviewed study.

The PerioLase MVP-7 variable pulsed Nd:YAG dental laser was shown to be FDA-approved and showed a 100 percent success rate after three months in achieving new connective tissue attachment (CTA) and regeneration of root surface, or cementum, in the subjects studied.



Laser therapy option to avoid surgery

http://www.telegraphindia.com/1080310/jsp/calcutta/story_8996516.jsp

March 10 , 2008 : Thulium laser, recently installed in some city hospitals, is being used to treat a variety of problems, from tonsillitis to enlarged prostate

Thulium targets only affected tissues, making the treatment safer than the therapy with older types of laser, like Holmium. Side-effects of Thulium therapy are also less severe.

"Earlier, lasers had deeper penetrations and hence, affected more tissues than were necessary," said Thorsten Bach, an urologist from Hamburg in Germany. He was in the city to take part in a workshop at Calcutta Medical Research Institute (CMRI).



Laser Helps Smokers Kick the Habit

http://www.wtoctv.com/Global/story.asp?S=7410596&nav=menu89_2

Nov, 26, 2007 : It's not the first time James tried to quit. He chewed gum, quit cold turkey and even underwent hypnosis to kick the habit. Nothing worked. So when he saw an advertisement for Laser Health of Savannah, he knew he had to try it.

The new technology is a 3B laser, usually used on people with persistent knee pain. The procedure is almost like acupuncture, without the needles. Technician Tracy Walsh applies the laser to 28 different points on James' face, neck and hands. Walsh says the procedure is totally painless and helps curb a smoker's cravings. "Certain cell functions are stimulated with the laser. And it will release endorphins, so those endorphins will help you so you're not actually feeling those cravings," she explained.

The laser treatment has a 65 percent success rate. The use of the 3B laser has not been approved by the Federal Drug Administration for either of these programs. Laser Health of Savannah is conducting a study under an independent institutional review board.



LASER BEST FOR EYELID SURGERY

http://www.carefair.com/html/Laser_Best_for_Eyelid_Surgery_3697.html

Nov 26, 2007 : According to Dr. Warren Lent, a plastic surgeon based in Los Angeles, eyelid surgery is best and faster when done using lasers. He said in a recent interview that "The CO2 laser offers patients the highest level of safety while at the same time offering the fastest return to work."

The press release further notes that CO2 laser immediately "welds or seals the blood vessels" when used as a surgical tool, and reduces the risk of excess bleeding during the procedure. Dr. Lent's research and work has also shown that using the laser also effectively minimizes both bruising and swelling hence hastening the healing process for patients, and patients did not need sedation.

In the press release, it was also noted that the "CO2 laser greatly reduces the risks in undergoing eyelid surgery."



LASER IMAGING BEATS THE BENDS

http://optics.org/cws/article/research/31877;jsessionid=71538DB750292886AA0181EBAC24BCFB

Nov 21, 2007 : Decompression sickness is a well-documented risk for divers and other people who experience sudden changes in pressure, but it's usually not detected until clinical symptoms appear. The new device could allow advance warning of the sickness by spotting microbubbles of nitrogen as small as 6 µm across in blood and tissues.

Most microbubbles in the blood stream of people suffering from decompression sickness are between 5 and 15 µm, about the size of a red blood cell, and readily spotted by the technique

The system uses optical coherence tomography (OCT), an interferometric technique that uses lasers to build up images of tissue just below the skin. In Larin's current prototype, a 1330 nm laser source with a spectral width of 110 nm and a power of 10 mW scans the subject at a scanning rate of 15 kHz. The light is delivered to an interferometer, one arm of which includes the test sample. The resulting interferogram is digitized using 14-bit analog-to-digital conversion, and the machine produces a 2D OCT image of the microbubbles present along with a graphical read out.



NEW LASER TREATMENT HELPS PEOPLE WITH GUM DISEASE

http://www.local10.com/health/14263131/detail.html

October 3, 2007 : An estimated 80 percent of adults in the United States currently have some form of gum disease. Fortunately Spitzer found Dr. Jason Luchtefeld, a Pompano Beach dentist working with a new FDA approved laser designed specifically for patients with gum disease.

"This laser, called the Perio-Lase, works in two ways," said Luchtefeld. "The light energy from the laser gently removes a tiny amount of diseased tissue and kills bacteria at the same time," he said. Once the treatment is complete, Luchtefeld said the body works to heal the area naturally. "Patients typically recover from this procedure faster than traditional surgery and have less pain," said Luchtefeld



LASER TEETH WHITENING PROCEDURE - KEY FACTS

http://pr-gb.com/index.php?option=com_content&task=view&id=25588&Itemid=9

02 October 2007 : Laser teeth whitening is also known as power bleaching or whitening. Even though it seems to be a little expensive, lots of people who are very concerned about their smile, especially actors, artists and those in the media prefer it to other teeth whitening procedures, as the results are faster and for the excellent.

Laser teeth whitening technology is the latest and superior tooth whitening systems are available today. It takes just an hour to undergo this kind of treatment. The treatment is very simple and painless when laser teeth whitening system is used. The procedure starts with a little preparation before getting into it actually. The dentist first cleans the teeth and it is very important because if the germs and plaque are present, it will hinder the whitening process. The lips and the gums are isolated before the procedure and a whitening gel is applied on the teeth by activating a specially designed light on it. The results are amazing as the teeth will be six to ten times whiter than the previous color and sometimes more than that can also happen. For people with extreme discoloration, one session may not be enough to achieve desired results and hence the treatment might be repeated until the white coloration is noticeable



Eye surgery leaves many with problems

http://www.newsobserver.com/news/story/721249.html

Sep 30, 2007 : Millions of Americans have undergone laser eye surgery to correct bad vision, and along with the procedure's popularity something else is coming into focus: its hazards.

Advertising stresses the surgery's safety, and most procedures are successful. Tiger Woods, who relies on keen eyesight as the world's best golfer, pitches it as a quick and painless way to restore sharp vision. Even the U.S. Air Force, long skeptical of the surgery, changed its policy in May to let people who had LASIK apply for pilot training. But every year thousands of Americans who undergo LASIK are left with chronic pain, dryness of the eyes, distorted night vision and even blindness, according to Food and Drug Administration statistics.



New laser treatment cures neck pain without surgery

http://www.channelnewsasia.com/stories/singaporelocalnews/view/302213/1/.html

SINGAPORE : A treatment without surgery is now available for those who suffer from neck pain due to a slipped disc.

The S$7000 treatment, which has been around for one year, uses a laser to vaporise part of the tissue surrounding the disk.

This reduces the pressure on the disc thereby alleviating the pain felt by the patient.



LASER HAIR REMOVAL SYSTEM - HOW DOES IT WORK?

http://pr-gb.com/index.php?option=com_content&task=view&id=21318&Itemid=9

24 September 2007 : Historically, hair removal has been one of the most painful tasks that a person must undertake. Think about all of the pain and trauma you go through every time you pluck a nose hair, cut yourself while shaving, or rip the hairs out of their follicles with a waxing. It makes many cringe just to think about pulling out one of their hairs.

But what if you didn't have to deal with all of that pain anymore? What if there was a better way to remove your hair?

Well, there is and it's called a laser hair removal system. The newly invented laser hair removal process is a technology that removes hair in a completely painless fashion through the use of lasers. No more pulling, no more waxing. Those days are done, thanks to the new laser hair removal systems that have been developed by doctors and health professionals from around the country.

However, with the laser hair removal process, you don't need to worry about your hair growing back immediately. The laser focuses its light directly into the hair follicle without causing any damage or pain to your skin. Essentially, the laser vaporizes the follicle, allowing the hair to simply fall out without allowing it to return for weeks, months, or even years on end. The ultra high tech laser hair removal system is a great way to get rid of those bothersome hairs that have been pestering you for far too long.



Laser scan of veins detects cancer

http://www.mtbeurope.info/news/2007/709023.htm

20 September 2007 : Technology that can detect tumour cells by scanning surface veins with a laser, eliminating the need for drawing blood, has been developed by Purdue University researchers.

By shining a laser on surface veins, such as those on the wrist and inside the cheek, researchers are able to reveal and count circulating tumour cells. In addition to being less invasive, the new method is able to evaluate a much larger volume of blood than what can be drawn from a patient for analysis

Researchers from Purdue's Cancer Center, Department of Chemistry and Weldon School of Biomedical Engineering collaborated with cancer and biotechnology experts from the Mayo Clinic to develop the technology

The technique uses a fluorescent tumour-specific probe that labels tumour cells in circulation. When hit by a laser, which scans across the diameter of the blood vessel 1,000 times per second, the tumour cells glow and become visible. The in-vivo flow detection was performed on a two-photon fluorescence microscope in Cheng's lab. The researchers compared several methods and found two-photon fluorescence provides the best signal to background ratio. The technology is able to scan every cell that is pumped through the vessel, He said.

The laser penetrates to a depth of 100 microns and is able to examine shallow blood vessels near the surface of the skin. Advanced optical technology could be incorporated into the technology platform and enable the method to reach deeper vessels that handle larger volumes of blood,



The brain dances to a laser tune

http://www.deccanherald.com/Content/Aug212007/snt2007082020314.asp

August 21, 2007 : Scientists are learning the language of the brain using optical excitation. Laser stimulation can serve as a musical conductor, manipulating the various kinds of neurons in the brain to reveal which important roles they play



LASER HAIR REMOVAL AS HIRSUTISM TREATMENT

http://pr-gb.com/index.php?option=content&task=view&id=3666

29 July 2007: Many men and women across the world choose to remove unwanted body hair. The reasons for use of lasers for hair removal can be cosmetic, social, cultural, or medical. Medical and cosmetic indications for laser hair removal also include hirsutism, which is a condition characterized by excessive terminal hair growth on face, chest, back, abdomen.

Laser hair removal is a relatively new method available for long-term hair reduction. Unlike electrolysis, laser treatment can target multiple follicles simultaneously. Since women with hirsutism have dark, thick hair which is different from the fine hair that some women have on their upper lip, chin, breasts or stomach, laser hair removal as hirsutism treatment is quite suitable.

The biggest advantage of laser hair removal treatment is that it may be used on large areas of the body. Use of lasers as a method for hair removal for hirsutism treatment is in fact the latest facial laser hair laser removal method offered by professional laser hair removal clinics. The different methods of laser hair removal available with these laser hair removal clinics are the ruby laser (694 nm), alexandrite laser (755 nm), diode laser (800 nm), and Nd:YAG laser (1064 nm).

A new laser system is set to revolutionalise this. Its unique green colour laser light is avidly absorbed by oxyhaemogloblin, the blood pigment. This means that during the procedure carried out on the prostate, the laser light automatically homes in on blood vessels and seals them whilst at the same time causing the obstructing prostate tissue to turn into vapour.

The procedure with the new system is carried out under a short general or spinal anaesthesia and usually takes about one to two hours. Laser cystoscopes are generally
