Chemists offer law enforcement crime solving tool

Gunshot residue comprises particles from the parts of the ammunition and firearm that explode or reside near points of explosion including the primer, propellant, and tiny particles of the cartridge case and gun itself. since residue can be recovered from several locations in the scene, it may be utilized for both physical and chemical evidence: GSR establishes that the shooting took place and a person participated in the shooting.

“If a crime is committed that involves a gun, we can examine the gunshot residue to help determine the size and type of ammunition used,” said UAlbany professor of chemistry and lead researcher Igor Lednev. “then through comparisons and elimination, it is quite likely to determine what kind of a gun was used in the crime.”

Lednev, a member of the White House Committee on Forensic Science, explained, “In the absence of a weapon and discernible ammunition remainders at a crime scene, the ability to analyze and positively identify ammunition and firearms would have a significant impact on the efficiency of a criminal investigation.”

The research team combined GSR with Raman spectroscopy, in which laser light of a specific wavelength is shined on a sample, sending its molecules vibrating. Well-suited for forensic analysis, spectroscopy does not destroy evidence, requires limited sample preparation, and has a range of applications including the identification of explosives, paint, textile dyes, drugs, and bodily fluids.

Lednev concludes that more analysis is needed before CSI teams employ the method in a courtroom. one day, investigators might even be able to flip through a database of Raman spectra of different ammunitions to more quickly link that crime-scene residue to a specific kind of gun.

Link between Periodontitis and Diabetes and Obesity

A researcher at the University of Illinois at Chicago College of Dentistry has received a two-year federal grant totalling $432,000, to continue a study concerning the relationship between periodontitis and type 2 diabetes and obesity. Dr. Keiko Watanabe, in a study published in the J. of Periodontology (July, 2008), showed that periodontitis accelerated the inception of insulin resistance in rats fed a high-fat diet. the new study will investigate how periodontitis affects related-diabetic complications, such as the pancreas, retina and aorta. Although this association between obesity and type 2 diabetes and periodontitis has been recognized for some time, the causes are still poorly understood. Dr.  Watanabe hopes that her new study will find the reasons why periodontitis can affect type 2 diabetes, insulin resistance, as well as damage organ. this way clinicians may better monitor those individuals at danger of developing the disease in the future. the researchers are hopeful of developing a plan to treat periodontitis, in order that insulin resistance will not hasten the onset of type 2 diabetes.  One main challenge by researchers is to prove causality between periodontitis and obesity and type 2 diabetes. the published reports are loaded with epidemiological or cross-sectional studies, and do not prove causality. Dr. Watanabe will be using female diabetic fatty rats for her animal model, as these rats more closely resemble humans that eat a high-fat diet and consequently develop insulin resistance and type 2 diabetes. Several published reports have shown that when periodontitis is treated in type 2 diabetic humans, there was significant improvement in glycemic control. however, in human studies, covariates need to be controlled for in order to make a comparation. this isn’t necessary in animal studies.

Dr. Oz offers health advice

By ELLEN STERLING

If doctors can be rock stars, then Mehmet C. Oz certainly qualifies. His daily television show is second in the daytime ratings and he draws crowds wherever he speaks.

While not quite as well known as Oz, Michael F. Roizen, MD, is Chief Wellness Officer of the Cleveland Clinic. He is also the researcher who created the RealAge scale that takes objective measures of individual’s health — weight, body mass, blood pressure, among them — and uses the numbers to determine the individual’s age when measured by these important health factors as opposed to the actual age in years. Oz and Roizen have co-authored the you.series of books (YOU on A Diet, YOU Having A Baby) a series of books dealing with health-related issues. Described by Oz as his “best friend,” Roizen is a frequent guest on the latter’s show.

The physicians were here in Las Vegas as guests of the Keep Memory Alive Foundation to speak February 12 at the Cleveland Clinic Lou Ruvo Center for Brain Health. Their topic was “Why We Do what We Do on the Dr. Oz Show.”

Their talk — they spoke separately with Oz up before Roizen and they closed with questions from the audience –was full of charts, photos and video. from it, the audience learned that the critically important thing they do on the Dr. Oz Show and, in fact, in their books and personal appearances, is try to get their audience to understand and accept that every person old enough to make decisions is responsible for his or her own health.

They even told the audience what “Elvis’ major contribution to us was and how much it was worth to America.”

Their talk was full of lists of things each of us can do to change our health for the better, starting with four basics

* Listen before trying to fix a problem. People want to be heard. think about what the person is really telling you. until you’ve listened and understand the problem, don’t suggest solutions.

* Ancient solutions work. Alternative therapies (acupuncture, for example) do work and that’s why they’ve been used for centuries.

* make it easy to do the right thing. Be there to help. if something is easy to do, there’s more chance it will get done. That’s the key to prevention.

* Feelings change minds. Telling someone smoking will damage their lungs is much less effective than showing a picture of a smoker’s lungs.

Oz is a cardiovascular surgeon at New York Presbyterian Hospital and, while passionate about preventive medicine and wellness in general, his particular crusade seems to be the prevention of atherosclerosis, the condition that occurs when fatty substances build up on the walls of arteries. This build up, called plaque, blocks the blood flow through the arteries and is the leading cause of death in the United States.

It is not, he said, a good feeling “when you walk into the operating room and know you’re going to take a band saw to the patient’s chest for surgery that could have been prevented.”

He noted that poor diet and environmental factors are both triggers of disease. “Monday morning is the most common time for heart attacks,” he said. “If you already have the plaque, the stress of beginning the work week can trigger the event.”

Oz urged each audience member to become “a smart patient.” to do this he suggested: keeping an up-to-date copy of your medical history so you can bring the physician the information.

He also recommended getting a second opinion. “Only 10 percent of patients get a second opinion and, one-third of the time, that changes their diagnosis,” he noted.

For optimum health, Dr. Oz listed the five factors that “determine 70 percent of how you age:”

* Blood pressure: the ideal is 115/75 and you should avoid foods and environmental factors like stress that may raise it.

* Smoking and other toxins harm your health and cause faster aging.

* Everyone should get 30 minutes of exercise each day.

* Eat a healthy diet that is easy to love; that is made up of things you like.

* Controlling stress in your environment can go a long way toward improving your health status.

He also recommended correct breathing techniques — deep breaths as used in yoga and martial arts — and told the audience that waist size should be no larger than half a person’s height. So, a person who is 64 inches tall should have a waist size of no more than 32 inches.

“These sound like soft, fuzzy solutions,” he acknowledged. “But, they’re not. They work.”

As he finished his talk, Oz said that in dealing with our health, “we all make mistakes but they can be corrected” and, thus, disease can be prevented.

Dr. Roizen is known as “The Enforcer” on Oz’s show because he will visit people and make sure theat their food intake and lifestyle is what they need to improve and maintain their health.

He began by saying “Most of us think we hit our peak quality of life between ages 25 and 35 and it’s all downhill from there.” He paused and said, “And it is. Your IQ declines about five percent over 10 years from that point on” but that is not inevitable.

“Before you’re 35, it’s your genes that determine your health. after 35, it’s your choices.”

Like Oz, Roizen repeatedly emphasized the fact that our lives, our health, are largely a result of the choices we make. Echoing Dr. Oz’s belief about correcting mistakes, Roizen said, “You can get a do-over in life, even with cancer, but remember that food is not Let’s make A Deal. Moderation does not work. it can be a killer.”

Looking at history, he told his audience, “In Norway in 1939, when the Nazis occupied the country and took away chocolate and other fats, the number of heart attacks plummeted. Today, we in the United States have two times more chronic disease than in Europe. when it comes to obesity we’re ahead of the rest of the world.”

Telling his audience that autopsies of children showed that some as young as six have definite signs of atherosclerosis and talked about lunch in an elementary school he visited. the cafeteria served the children donuts with frosting and sprinkles, claiming the sprinkles are fortified with Vitamin A. “But that lunch was 3,400 calories. And it was being fed to food-insecure children so it was possible that this was the only meal they’d get that day. no wonder we’re ahead of the rest of the world in obesity.”

Using graphs, both doctors pointed out that the US has lost fundamental parts of our economy — particularly manufacturing jobs — to other countries and laid the blame squarely on our shoulders because, as a nation, our diets are putting our health at risk and driving up medical costs. thus, manufacturers cannot afford health insurance for their workers and workers are missing work due to illness.

“The choices we make,” Roizen said, “will determine if the US can compete for jobs.”

With this in mind, Roizen suggested a set of steps we should all take to improve our health:

* We can control what goes in our bodies and we should do so.

* Avoid toxins like tobacco and second-hand smoke.

* Avoid Bisphenol A (BPA), a chemical compound used to make plastics. Last year, Canada became the first country to totally ban BPA. since early exposure to BPA is the time in life when the chemical can have the greatest effects, Roizen suggested avoiding plastic baby, water and other bottles and, even, avoid handling those shiny receipts you get that are often coated with BPA. “It can be transferred from your hands to a child’s body,” he said.

* Avoid excess radiation. Don’t have a medical test that involves radiation unless it is absolutely necessary.

* Walk 10,000 steps a day.

* in addition to walking, do other forms of physical activity, notably cardiovascular and muscle-building exercises.

* Have a buddy you can call on when you feel your motivation to start living a healthier lifestyle flagging. He also strongly suggested that the buddy be female because women tend to be more knowledgeable about these issues and will dish out some tough love if necessary.

* Manage your stress with meditation and physical activity and by avoiding those stressful situations that you can avoid.

* take half a multi-vitamin two times each day, consider taking two baby aspirin daily for heart health.

* Sleep six and a half to eight hours daily.

* Love something and do it every day.

To this, Dr. Oz added, “Your genes load the gun and environment pulls the trigger,” then talked about the fact that some things cannot be avoided. For example, he said, even though he eats right — he’s a vegan — meditates and exercises, a colonoscopy revealed a pre-cancerous polyp. He was, he said genetically predisposed to the disease and there was a trigger and, sometimes, that cannot be helped.

Finally, that major contribution Elvis made is well worth noting.

Showing a photo of the star getting a polio vaccination in 1956, they said that until that photo appeared around the world there was widespread resistance to the vaccine. But, once people saw the photo, they decided that, if Elvis could do that, they could, too. “Thus,” Roizen said, “Elvis played a big part in the eradication of polio in our country.”

In the end, the message was simple and clear: like Elvis’ choice to get that polio inoculation, we each have choices we can make in life and making the right choices for health benefits each of us and our country as a whole.

So, who do not know Kenny Rogers? the man who makes a poker game most popular in the West with his old soul song "the Gambler by early 1980. It has long been a staple of country music scene, though it seems a bit 'late when it comes to pop music that passes for country now. It's nothing that surprises many as Rogers has been linked to a series of duets with stars and others. Of course, there is the issue that had many wives. He has repeatedly admitted that is incredibly difficult to live and can be a bad husband occasionally.

Many people now wonder how he managed to get the new look of youth. Once the researcher was strong which made the songs that she sang the far West, and so have some credibility but now that everything has changed. there was some plastic surgery Kenny Rogers "is happening and what is not a surprise to anyone in scene.Early career Rogers was often teased about his time his weight . So it has never been called fat, it was heavy and at times seemed a bit 'bloated. For this he enlisted the help to get more at the forefront of new stars appeared.

He managed to get his weight under control and that meant a lot of work, but it worked for him. Then to add insult to injury,, plastic surgery, he was always looking a little old. the number of lines around his eyes showed signs of his lifestyle which sometimes reflected the men in his songs. His constant theme of life finally caught up with him to go and there was not much he could do about it. Evil intervention was done and plastic surgery Kenny Rogers 'plastic does not seem to be answer.

Kenny Rogers' seems to be a disaster from the beginning. He went to some of Aging Research and ends supported by research horrible. this is one of the most painful for Rogers as he tells a good number of journalists is not the way it was intended to look, but what he did. It 'knows that the skin around the eyes is too tight and her face seems to be able to rip open. though his new wife says it looks great, knows better and has enlisted the help of a team of plastic surgeons to undo what has already been done.
