I am going to treat myself to some new glasses soon. I have had my pair for a very long time and I think it is about time that I got something on trend. I have been looking around and have seen some Kawasaki glasses that I thought looked rather cool but I was not sure that they suited me really. It woudl be nice to have them but I do not want something that changes the way that I look too dramatically. I was thinking that the Silhouette glasses might be better because they are more like the style that I have already, but they are more modern looking.

I also want to get some designer sunglasses with my prescription in the lenses. I will need a new pair as my prescription has changed and it only seems right to change both especially as I sometimes change them when I am driving and do not have time for my eyes to adjust to the different strength of lens and so it is very dangerous. It will be nice to have a new cool pair as well, I love wearing sunglasses but obviously cannot see out of normal ones and so cannot keep changing the style of the ones that I wear which is a bit annoying,

Digestion and excretion are important cycles of human body. Without these two procedures human body stinks and becomes a hidden waste material. These two procedures should run one after the other, otherwise health of people deteriorates. No doctor can solve problems related to abdomen, only Gastroenterologist can clearly understand problems related to abdomen and intestine. Utah is well known, small populous state of USA. This western state has many hospitals and shopping malls. Gastroenterologists in Utah are proficient in solving digestive problems.

Utah Gastroenterologist can clearly understand digestive health of a patient. Utah gastroenterologist gives proper treatment to patient. Gastroenterologists develop mental strength in patient. Gastroenterology is a typical and most difficult task. Without special equipment, understanding the intestinal and abdomen status becomes difficult. It is in this situation doctors prefer Endoscopy. Even though Endoscopy is a traditional method, it is still existent at this place.

Endoscopy is actually defined as a diagnostic procedure in which doctors access the interiors of internal organs of body. Endoscope is used in Endoscopy: This instrument has a small tube, which acts on total internal reflection of light phenomenon. This tube is sent through mouth into abdomen to study internal organs. Utah Endoscopy is a simple procedure. Utah gastroenterologists can perform this procedure efficiently.

Hair loss is the potential problem to which men and women fall prey at some point of time or the other. There can be numerous possible causes for the loss of hair. Dieticians and hair experts accrue reasons such as protein deficiency, calcium deficiency, hereditary diseases, lethal diseases such as tumors or cancers can also result in substantial hair loss. Still many of the people also complain of thinning hair.

This is another kind of hair problem, which has left millions grappling with the situation. Hair thinning primarily occurs as the result of weakened hair follicles, and as the result of which hair filaments become week and began to fall one after the other. The cause of thinning hair has also been attributed to hereditary linked problems. With the research and development in medical science, the problem of hair fall, male and female pattern baldness has been seriously dealt. Today, there are available hair loss treatment techniques that can change your personality by giving you back your lost hair. Many of these hair loss treatment methods are natural and have no side effects on human tissues. The best thing is that you can even try them out along with your regular regimen.

Most of the human beings have an innate desire to look beautiful and spruced up all the time. They try every method possible to give them shape, have beautiful and shining hair and all the more have sharp and dynamic features to attract the attention of opposite sex. They make use of synthetic and natural products available in the market to realize their dreams. Some are successful, while others are not. Natural hair loss treatment is an amazingly new way to keep you chick and smart all the time and add a tint of dynamic personality to your mien. What’s more, natural hair loss treatment procedures are pretty safe and easy to use; and therefore, the user has no hassles to try them out, even without going in for any health expert.

However, for those who are still grappling with pot belly or a hanging tummy, you have those over the counter quick weight loss remedies available for you. These smart remedies can really bring you in shape and have your confidence raised to higher levels. However, a word of caution here! Quick weight loss is mostly done by incorporating synthetically prepared constituents. Check it out that you are having a natural supplement for losing your weight.

Overactivity of a brain enzyme, called p70 S6 Kinase 1, or S6K, may play a role in preventing weight gain and obesity, said researchers at Albert Einstein College of Medicine of Yeshiva University.

For the study, scientists focussed on the hypothalamus in the brain, which controls body temperature, hunger, and thirst. Specialized nerve cells in the hypothalamus sense whether the body contains adequate amounts of nutrients and stored body fat. The cells then send out signals telling other parts of the brain to adjust food intake, metabolic rates, and physical activity accordingly — keeping the body’s caloric intake in balance with calories burned.

Thus, in order to delve in detail into the nutrient-sensing pathways and how they go awry in metabolic disorders, the researchers focused on an enzyme called p70 S6 Kinase 1, or S6K, which plays a role in regulating the growth and proliferation of all cells, including nerve cells.

“It turns out that this enzyme, and the pathway it regulates, is nutrient sensitive — that is, S6K activity increases in the presence of carbohydrates and protein. This led us to believe that S6K might not only be involved in maintaining the structure and function of individual cells, but also in regulating the energy balance of the whole body,” said the study’s principal investigator, Gary J Schwartz, Ph.D., professor of medicine and neuroscience at Einstein.

To test their hypothesis, the researchers injected rats with special viruses that selectively raise or lower S6K activity. They injected the viruses directly into the lower-middle, or mediobasal, portion of the hypothalamus, an area rich in nutrient-sensing nerve cells.

“When we raised the activity of the enzyme, we saw reductions in food intake, in body weight, and in production of peptides [small chains of amino acids] that normally stimulate feeding. When we lowered S6K activity, we saw essentially the opposite response,” said Dr Schwartz.

Schwartz said that it was important how increased S6K activity reduced the rats” food intake by reducing the average size of meals rather than changing the number of meals over the course of a day.

Thus, the animals apparently were sated faster and therefore ate less at every meal.

In another experiment, the researchers tested whether increased S6K activity would protect against the natural tendency of mammals on a high-fat diet to overeat.

When animals on a high-fat diet were given the S6K-enhancing virus, they overate less and gained weight more slowly than control animals, the researchers report. In addition, the virus-enhanced animals had lower body-fat levels and better glucose tolerance than the control group.

On the whole, the study shows that S6K acts as a kind of food-sensing thermostat in mammals, increasing or decreasing feeding behaviour and metabolism to maintain a normal energy balance.

“These findings show that it may be possible to control obesity and other human metabolic disorders by developing drugs that regulate S6K activity,” said Schwartz.

The findings were reported in Cell Metabolism.

The Vatican raised its opposition to embryonic stem cell research, the morning-after pill, in vitro fertilization and human cloning to a new level Friday in a major new document on bioethics.

But in the document, the Vatican also said it approved of some forms of gene therapy and encouraged stem cell research using adult cells. And it said parents could in good conscience inoculate their children with vaccines produced with cells derived from aborted fetuses.

The Vatican’s Congregation for the Doctrine of the Faith issued “The Dignity of a Person” to answer bioethical questions that have emerged in the two decades since its last such document was published.

With it, the Vatican has essentially confirmed in a single, authoritative instruction the opinions of the Pontifical Academy for Life, a Vatican advisory body that has debated these issues for years.

The Vatican’s overall position is formed by its belief that human life begins at conception, and must be afforded all the consequent respect and dignity from that moment on. The Vatican also holds that human life should be created through intercourse between husband and wife, not in a petri dish.

As a result, the Vatican said it opposed the morning-after pill, even if it doesn’t cause an abortion, because an abortion was “intended.” In the use of drugs such as RU-486, which causes the elimination of the embryo once it is implanted, the “sin of abortion” is committed; their use is thus “gravely immoral.”

The Vatican also said it opposed in vitro fertilization because it involves separating conception from the “conjugal act” and often results in the destruction of embryos. The Vatican supports, however, techniques that help couples overcome obstacles to getting pregnant.

In the document, the Vatican elaborated on a host of issues surrounding assisted fertility, saying it:

_Opposed the selective reduction of embryos often used in in vitro procedures since it essentially is abortion.

_Opposed pre-implantation diagnosis of embryos since it may be followed by the destruction of those embryos deemed defective or otherwise undesirable.

_Opposed freezing embryos, since it is “incompatible with the respect owed to human embryos” and also means they were created in vitro.

It said that, while freezing eggs is not in itself immoral, it becomes unacceptable when it occurs for the sake of artificial procreation.

The Vatican lauded as “praiseworthy” the suggestion by some to let infertile couples “adopt” the thousands of frozen embryos that have been produced in vitro over the years. But it said such adoptions present a host of medical, psychological and legal problems.

The instruction also weighed in on research involving stem cells, cloning and gene therapy.

The Vatican stressed that it fully supported research involving adult stem cells. But it said obtaining stem cells from a living embryo, even for the sake of effective therapies, was “gravely illicit.”

It said gene therapy on regular cells in the body other than reproductive ones was in principle morally licit since it sought to “restore the normal genetic configuration of the patient or to counter damage caused by genetic anomalies.”

But it said that cell therapy which seeks to correct genetic defects with the aim of transmitting the therapy onto offspring was more problematic.

“Because the risks connected to any genetic manipulation are considerable and as yet not fully controllable, in the present state of research, it is not morally permissible to act in a way that may cause harm to the resulting progeny,” the document said.

In the document, the Vatican also:

_Repeated its opposition to human cloning for both medical therapies and reproduction. Such techniques could result in an individual being subjected to a form of “biological slavery from which it would be difficult to free himself.”

_Said parents could in good conscience use a vaccine for their children that was developed using cell lines from an “illicit origin.” Religious groups in the United States have pressed the Vatican to issue a statement concerning the morality of using vaccines developed using cell lines derived from aborted fetuses.

“Grave reasons may be morally proportionate to justify the use of such ‘biological material,’” the instruction said, adding that the parents would have to make known their disagreement with the way the vaccines were developed and press for alternatives.

But the document was very strong in stressing that researchers using such material were in a different position and had a greater degree of responsibility. It said they had a moral duty to remove themselves from the “evil aspects” of the original, illicit act — even if they and their institutions had nothing to do with it.

An experimental drug cured guinea pigs infected with a fatal hemorrhagic fever virus, raising hope for its use in a broad range of viral diseases including influenza, hepatitis C, HIV, Ebola and others, U.S. researchers said on Sunday.

“This is a whole new strategy for making antiviral drugs,” said Dr. Philip Thorpe, professor of pharmacology at the University of Texas Southwestern Medical Center at Dallas, whose research appears in the journal Nature Medicine.

Instead of attacking the virus directly, bavituximab, made by Peregrine Pharmaceuticals Inc, takes advantage of a defense mechanism used by the virus to hide from the immune system, Thorpe said.

When cells are under attack by a virus, this stress causes a fat molecule called phosphatidylserine, which normally lines the inside of the cell, to flip to the outside. “It’s like wearing your clothes inside out,” Thorpe, a scientific adviser to Peregrine, said in a telephone interview.

Bavituximab, a genetically engineered antibody, seeks out and attaches itself to these turncoat cells, flagging them for the immune system, which can then mount an attack,

“When injected into the bloodstream, bavituximab circulates in the body until it finds these inside-out lipids and then binds to them,” Thorpe said in a statement.

“In the case of virus infection, the binding raises a red flag to the body’s immune system, forcing the deployment of defensive white blood cells to attack the infected cells.”

Thorpe said conventional antiviral drugs try to exploit some property of the virus, but these drugs are often quickly defeated as the virus mutates.

By targeting an aspect of infected cells in the host, he thinks bavituximab is less likely to lose effectiveness, which commonly happens when a virus mutates.

In the study, Thorpe and his colleagues tested the compound on guinea pigs in an advanced stage of infection with a form of the Lassa fever virus, a disease that affects parts of West Africa.

Half of the animals treated with the drug alone were cured. When the researchers tested it in combination with the antiviral drug ribavirin, a drug that keeps a virus from replicating, 63 percent of the guinea pigs lived.

Thorpe said the findings suggest the drug might be effective on other types of hemorrhagic viruses, such as Ebola and Marburg. But this lipid flipping also occurs in cells infected with many other viral infections, including influenza, smallpox and rabies.

Peregrine is conducting early phase clinical trials of the drug in people with hepatitis C and human immunodeficiency virus, or HIV, which causes AIDS. And it has more advanced trials under way in cancer.

“We think it has tremendous potential,” Steven King, president and chief executive of Peregrine, said in a telephone interview. Peregrine funded the research along with the National Institutes of Health.

People paralyzed by spinal cord injuries have been offered a new hope after Otago University researchers claimed the wounds could soon be “repaired” using cells from patients’ noses.

The New Zealand’s Health Ministry’s ethics committee has approved an application by the Spinal Cord Society, which will open the way for a clinical trial involving 12 patients.

Noela Vallis, the society’’s president, said there was no shortage of volunteers ready to take part.

“Some have already gone overseas out of a sense of frustration that they can’t access it [the experimental treatment here,” the NZPA quoted Vallis, as saying.

Research director Jim Faed, who heads the Spinal Cord Society’s lab at Otago University, and his team is focusing on two promising cell types: one is a kind of adult stem cell produced by a patient’’s own bone marrow.

However, researchers are likely to begin trials using olfactory (scent receptor) cells from the patient’’s nose, injecting them into damaged spinal cord.

“The olfactory tissue in the nose is unique because it is the only place in the body where there is constant replacement of nerve cells throughout life,” Dr Faed said.

“There is growing medical opinion that these cells can help overcome the blocks that prevent nerve cells regenerating after damage to the spinal cord,” the expert added.

The nasal tissue acts like “nurse cells”, providing growth factor hormone to nerve cells, enabling them to make “meaningful connections”.

On international basis, several research groups have done animal trials using the cells, however, there has been only one human trial – in 2006 in Portugal.

The Otago group is in contact with Portuguese neuropathologist Carlos Lima, who pioneered that trial.

Faed said some participants experienced side effects, but they were “few and manageable” and none had been fatal. Positive benefits for patients included return of some muscle function and sensation in parts of the body, which previously had no feeling, he said.

Faed said the Dunedin lab hoped to get full approval for the trial before Christmas, and would then begin recruiting patients. The first 12 could start treatment next year.

A unique form of bone marrow transplantation is the only safe and effective cure for sickle cell disease, researchers at Children’s Hospital of Pittsburgh report.

Traditional bone marrow transplants rely on heavy doses of chemotherapy prior to transplant in order to destroy a recipient’s bone marrow so it won’t reject the donated marrow. But that makes patients vulnerable to dangerous complications, something that’s viewed as an unnecessary risk, because sickle cell disease typically isn’t life-threatening, the researchers said.

This new transplant method relies on reduced intensity conditioning (RIC) regimens, which are less toxic to patients and eliminate life-threatening side effects generally associated with bone marrow transplantation. This means transplants can be offered to patients with severe sickle cell disease.

The researchers at Children’s Hospital, part of the University of Pittsburgh Medical Center, reported that six of seven sickle cell patients who received RIC bone marrow transplants in the last decade now have donor marrow and are free of sickle cell disease symptoms.

The report was published in the November issue of the journal Biology of Blood and Marrow Transplantation.

“Bone marrow transplant is the only known cure for sickle cell disease. But doctors have avoided performing them in these patients, because complications from a traditional bone marrow transplant can be life-threatening,” Dr. Lakshmanan Krishnamurti, a pediatric hematologist/oncologist and director of the Sickle Cell Program at Children’s Hospital, said in a hospital news release. He helped develop RIC bone marrow transplants.

“Through the reduced-intensity approach we developed, the potential for complications is dramatically lessened. This study offers hope for a cure for thousands of patients with severe sickle cell disease,” Krishnamurti said.

Sickle cell disease, an inherited blood disorder, affects about 80,000 people in the United States, primarily blacks. The disease can cause agonizing pain, strokes, damage to internal organs, and a shortened life expectancy.

If your foot often falls asleep and there are cuts or bruises on them that cause no sensation, brace yourself - it may be a case of diabetic foot.

With World Diabetes Day falling on Friday, experts have a word of advice. Leading a life of discipline and being cautious with one’s feet is the key to living with diabetes and dealing with the potential risk of gangrenous infection is simple, they say.

“Diabetic patients are often lazy about basic instructions - following a disciplined routine of taking medicines and regular exercises as prescribed. These are essential to keeping the circulation of blood and sugar levels in check,” said Ashok Jhingan, diabetologist and chairman, Delhi Diabetes Research Centre, told IANS.

Diabetes is a growing problem on the Indian subcontinent and in the Middle East.

According to the International Diabetes Federation (IDF), there were an estimated 40 million people with diabetes in India in 2007 and this number is predicted to rise to almost 70 million people by 2025.

“When a normal person wakes up in the morning, he goes to the mirror to look at his face. But a diabetic needs to look at his feet with the same care,” Jhingan said.

This is because the symptoms and signs of a diabetic foot include numbness or tingling in the feet, persistent sensation of cold feet, ulcerations on the foot or the toes.

“One must also be wary of small cuts or burns that can develop into gangrene or deformities on the toes and the foot,” Jhingan explained.

A recent study compiled by Kushagra Katariya, CEO Artemis Health Sciences and cardio thoracic surgeon, ahead of World Diabetes Day on Nov 14, found that approximately 5 percent of diabetics develop foot ulcers and 12 percent develop poor leg and foot circulation and every 30 seconds a lower limb is lost to diabetes.

“Unfortunately as a result of these problems, a diabetic is 15 times more likely to have an amputation of the leg than a non-diabetic,” Katariya said.

Diabetic foot problems can occur at any age and after any amount of time following someone being diagnosed as a diabetic.

“However, most patients with diabetic foot problems are older, as circulation gets poor with advancing age,” he added.

It is important for diabetics to get their feet regularly checked by a healthcare professional that specialises in this field, feel doctors.

“If there is a small infection, it can be controlled before it develops into a gangrene-like threat - the dead skin can be scraped, aspirin like drugs for speeding circulation to wounded areas can be prescribed, but first the diabetic must check his feet and be careful,” Jhingan observed.

In some cases, the blood circulation in diabetes patients is so bad that it can cause vascular blockages. These can be removed surgically but also through an angioplasty or laser.

“The doctor may order simple tests such as a vascular ultrasound to check the circulation in the legs. More advanced tests may include a CT-Angio or an MRA to look at the vascular supply,” said Katariya.

Many diabetic foot problems can be nipped in the bud by raising patient awareness to potential problems - watch your weight, keep blood sugar levels in control and get regular checkups.

“Diabetics should always buy footwear in the evenings,” Jhingan quipped, “not in the mornings as poor blood circulation causes the foot to swell in evenings - the shoes should not be tight or smaller. Comfortable soft soled footwear should be worn.”

In winters, the diabetic foot is often likely to be regarded as a chill bite.

“In which case the patient should be doubly cautious - keep warm but avoid prolonged exposure to hot water - this can cause bacterial infections and non-healing ulcers in diabetic patients, as their wounds take longer to heal. Due to loss of sensation in their feet, diabetics often don’t come to know about such injury early enough,” Jhingan averred.

In India almost 40,000 legs are amputated every year due to diabetes alone.

“Due to a gradual decrease in vision, diabetic patients tend to wound themselves. And due to a simultaneous loss of sensation in the feet, they do not feel the pain and hence the wound is ignored, causing prolonged infection - the limb then has to be amputated,” Jhingan said.
