Regular doses of ibuprofen extended the lifespan of multiple species, according to research published in the journal Public Library of Science, Genetics.
"We first used baker's yeast, which is an established aging model, and noticed that the yeast treated with ibuprofen lived longer," said Dr. Michael Polymenis, an AgriLife Research biochemist in College Station. "Then we tried the same process with worms and flies and saw the same extended lifespan. Plus, these organisms not only lived longer, but also appeared healthy."
He said the treatment, given at doses comparable to the recommended human dose, added about 15 percent more to the species lives. In humans, that would be equivalent to another dozen or so years of healthy living.

So two of the diets in the study were high in carbs overall, but one was made up of low-glycemic-index foods while the other was composed of high-glycemic-index foods. The other two diets were low in carbs overall, with the same breakdown or low- and high-glycemic items
In fact, among those eating the high-carb diets, those consuming low-glycemic-index foods had worse insulin response and higher LDL cholesterol…
we did not show that the glycemic index of the carb really had any favorable effect," says Sacks.
That suggests that all the attention to knowing the glycemic index of various foods—and basing your eating habits on these numbers—may not be worth the effort.'
Speed. That's key to ending the Ebola epidemic, says the director of the U.S. Centers for Disease Control and Prevention.
Dr. Thomas Frieden is visiting West Africa this week to figure out how to reduce the time it takes to find new Ebola cases and isolate them.
Otherwise, Ebola could become a permanent disease in West Africa.

A metal-detecting blood test that can give vital early warning of breast cancer is being developed by Oxford University scientists.
They hope the inexpensive and simple test will spot the disease long before a woman develops a lump – and say it could be used in a national screening programme.
Picking up the cancer at the earliest stages when it is easiest to treat could save thousands of lives, as well as spare patients and their loves ones the pain and distress of prolonged illness.
Researcher Fiona Larner said: 'Prevention is better than cure.
'There is a survival rate of about 80 per cent for breast cancer but the earlier you can detect it, the more chance you have of treating it.

'Google Inc. is designing tiny magnetic particles to patrol the human body for signs of cancer and other diseases, in the latest example of the Internet giant's sweeping ambition.
Google said its nanoparticles, less than one-thousandth the width of a red blood cell, would seek out and attach themselves to cells, proteins or other molecules inside the body. The company also is working on a wearable device with a magnet to attract and count the particles, as a monitoring tool.
The goal is to provide an early warning system for cancer and other diseases, with an eye toward more effective treatment.
"Every test you ever go to the doctor for will be done through this system," said Andrew Conrad, head of the Life Sciences team at the Google X research lab, who disclosed the project on Tuesday at The Wall Street Journal's WSJD Live conference. "That is our dream."'

'The missteps and delays in diagnosis of the Liberian man prompted some states to impose or consider restrictions on travelers coming from the West African countries where the virus has killed nearly 5,000 people.
Responding to concerns that mandatory quarantine would inhibit doctors and nurses from traveling to West Africa, Cuomo said New York wanted to encourage personnel to go, lauding their "valor" and "compassion," while also protecting public safety at home.
"These people are extraordinary for their valor and their courage and their compassion," Cuomo said. "Anything we can do to encourage it, we want to do."
He added that New York was not changing the policy announced on Friday.

Technologies like this allow us to imagine a new form of quarantine. Rather than relying on primitive instruments, indiscriminate profiling or questionnaires, we should consider running a pilot program to test asymptomatic travelers using sensitive P.C.R.-based techniques. Obviously, such technologies are expensive, but the cost is not prohibitive. A typical P.C.R. reaction, including labor, costs between $60 and $200 (we have already spent 100 times more disposing of the contaminated sheets from the home Mr. Duncan stayed in). Since the test takes about a third of the time of a trans-Atlantic flight, the flight would become the quarantine.
Huge logistical questions would need to be solved. Where would such a screening test be administered — before departure from West Africa, or upon landing? Could we imagine a walking quarantine in which travelers were granted provisional entry, but recalled if they tested positive? What infection precautions would need to be in place for such testing? What forms of consent would be required? Who would bear the costs? Who exactly would be tested?'

'Dr. Gavin MacGregor-Skinner, a specialist in treating Ebola, sounded the alarm today on CNN about how ill-prepared U.S. customs is when dealing with visitors from Ebola-stricken areas.
MacGregor-Skinner, an Assistant Professor, Department of Public Health Sciences at Penn State University, International Development Consultant, told Jake Tapper about how dangerous Ebola is.
"When my team was in Nigeria and we were treating Ebola patients the first thing they said to me was 'Should we tell the truth?' 'Yeah when you come back we're telling the truth.'
As we flew out of Nigeria I had my temperature taken and I was interviewed twice. As I came through Germany I had my temperature taken I was interviewed and questions were asked 'Where have you been? What have you done?'
When I got back to Washington D.C. I said 'I've been working with Ebola patients." I was told 'Welcome back. Off you go!' No one took my temperature. No one asked me any questions. So we told the truth. There was no process, there was no program here to make sure we were OK."'
But the system has its limits, relying on the traveler to reveal whether he or she has been exposed. And it leaves it to local officials to conduct the screening as they see fit, Dr. Cohen said. It is unclear how consistently or effectively those screenings are conducted across West Africa, and Dr. Cohen said she did not know how many potential travelers had been caught by screeners — if any.
"Our expectation is that people who are sick or people who are exposed should be getting the message they shouldn't be traveling."'

'U.S. health officials said on Tuesday the first patient infected with the deadly Ebola virus had been diagnosed in the country after flying from Liberia to Texas, in a new sign of how the outbreak ravaging West Africa can spread globally.
The patient sought treatment six days after arriving in Texas on Sept. 20, Dr. Thomas Frieden, director of the U.S. Centers for Disease Control and Prevention (CDC), told reporters on Tuesday. He was admitted two days later to an isolation room at Texas Health Presbyterian Hospital in Dallas.
U.S. health officials and lawmakers have been bracing for the eventuality that a patient would arrive on U.S. shores undetected, testing the preparedness of the nation's healthcare system.

With three new districts under quarantine, about one-third of Sierra Leone's 6 million people are now living in areas where their movements are heavily restricted. In parts of Sierra Leone and in neighboring Liberia where these cordons have been used in this outbreak, food prices have soared, some markets have shut and the delivery of goods has slowed.'

Although respiratory support can ease problems with breathing and prolong survival, it does not affect the progression of ALS. Most people with ALS die from respiratory failure, usually within three to five years from the onset of symptoms. The median survival time from onset to death is around 39 months, and only 4% survive longer than 10 years. Physicist Stephen Hawking has lived with the disease for more than 50 years, though he is an unusual case.

Gastroenteropancreatic Neuroendocrine Tumors (GEP-NET's) are a range of tumors that mostly keep their original function, producing endocrine hormones.
The disadvantage of that is the havoc they wreak on the body due to all sorts of hormonal imbalances caused by the hormones they produce. On the other hand, the level of differentiation is a strong indicator of how aggressive a tumor is: the better a tumor is differentiated e.g. keeps the features of its originator, the least invasive and prone to metastasis it is.
Just to illustrate how mild these tumors can be:
- As many as 10% of autopsied persons in the general population have been reported to have one of these without ever having had any symptoms during their life.
- Up to 30% of detected GEP-NETs are so well differentiated they're strictly not cancers. I have even come across an article where insulinomas, the most common type of GEP-NETs were benign in 90% of the cases.

'In a strategy that combines two of the hottest ideas in cancer research, scientists at the National Institutes of Health said they successfully attacked a woman's disease by using her immune system to home in on genetic mutations unique to her tumors.
The findings, published Thursday by the journal Science, come from just one patient—a 45-year-old woman in Montana. But researchers said her case, in which she received billions of immune cells specially grown to target her tumors, amounts to evidence the technique may be a way to treat many common cancers now considered difficult to target with the immune system.
So-called immunotherapy has so far shown the most promise in relatively rare cancers such as melanoma and kidney cancers.
This new approach "represents the blueprint for making immunotherapy available to treat common cancers," said Steven A. Rosenberg, chief of the Surgery Branch at the National Cancer Institute's Center for Cancer Research and senior author of the study. "We've figured out a way to target what is absolutely unique on each cancer. That is the mutations that make the cancer a cancer."'

'Trying to find out the price of a medical service is a headache for consumers. When researchers called hospitals around the country to find out the cost of a hip replacement, only 10 percent were able to provide an answer. About 332,000 total hip replacements were performed in the U.S. in 2010. Shouldn't it be simple to find out the price of something that's bought and sold 900 times a day?
Three of the U.S.'s largest health insurers plan to make what they pay for medical care more transparent to consumers. Aetna (AET), Humana (HUM), and UnitedHealthcare (UNH) are joining with a nonprofit called the Health Care Cost Institute (HCCI) to turn their databases of medical claims into a useful online tool for consumers.
When the yet-to-be-named website goes live next year, anyone will be able to type in a medical service and search for prices, says David Newman, executive director of the HCCI. The site will show the average price paid by insurers in a given Zip Code (or wider areas if not enough data are available). It will also show a range of high- and low-end prices to indicate how much variation there is for a given service. He likens the information to car-buying site Edmunds.com.'

'Mayo Clinic researchers announced a landmark study where a massive dose of the measles vaccine, enough to inoculate 10 million people, wiped out a Minnesota woman's incurable blood cancer.
The Mayo Clinic conducted the clinical trial last year using virotherapy. The method discovered the measles virus wiped out multiple myeloma cancer calls. Researchers engineered the measles virus (MV-NIS) in a single intravenous dose, making it selectively toxic to cancer cells.
Stacy Erholtz, 49, of Pequot Lakes, was one of two patients in the study who received the dose last year, and after 10 years with multiple myeloma has been clear of the disease for over six months.
"My mindset was I didn't have any other options available, so why wouldn't I do it? I had to have failed all conventional treatment to do that trial. That actually happened last March," Erholtz told KARE. "It was the easiest treatment by far with very few side effects. I hope it's the future of treating cancer infusion."
Steven Russell, a Mayo Clinic hematologist, spearheaded the study and said the concept was previously tested in mice, but never in humans.
"It's a huge milestone in that regard," said Russell. "We have known for some time viruses act like a vaccine. If you inject a virus into a tumor you can provoke the immune system to destroy that cancer and other cancers. This is different, it puts the virus into bloodstream, it infects and destroys the cancer, debulks it, and then the immune system can come and mop up the residue."
Two multiple myeloma patients were chosen because they are immune-compromised, and can't fight off the measles before it has time to attack cancer. Both had limited previous exposure to measles, and therefore fewer antibodies to the virus, and essentially had no remaining treatment options. Of the two subjects in the study, Stacy was the only to reach full remission. The other patient's cancer returned after nine months.
Russell believes it's still a medical milestone, and he hopes his team can one day transform this research into a single shot cure.
"It's like a call to action. It's not just good for our virus. It's good for every virus everybody's developing as a cancer therapy. We know this can happen," said Russell.
Mayo researchers are also testing the measles virus's effectiveness at fighting ovarian, brain, head and neck cancers and mesothelioma. They are also developing other viruses that seem to have potential to kill cancer cells.
"I think it's just remarkable. Who would have thought?" said Erholtz, who said she returns to the Mayo in June for a check up.
The Mayo is moving immediately into a phase two clinical trial involving more patients with a goal of FDA approval within four years.'

‘2 Orlando health workers ill after exposure to MERS patient’
‘There is a second confirmed case of MERS imported into the United States, the CDC announced Monday.
Officials from the Centers for Disease Control and Prevention and the Florida Department of Health are investigating.
The first U.S. case was reported this month in Indiana.’

The patient, at Community Hospital in Muncie, Indiana, is a health care worker who had traveled from Saudi Arabia, where the virus was first seen.
"All of the tests in close contacts have been negative," Don Fesko, CEO of the hospital, told a news conference. Officials said about 50 health workers had contact with the patient before they began taking extreme measures -- wearing masks, gloves, gowns and eye protection.
"All of the tests in close contacts have been negative."
The patient is in good spirits, has been taken off supplementary oxygen, has been walking around and is cooperating with isolation precautions, officials said. Family members have been asked to isolate themselves and to wear face masks when they go out in public, just in case they are infected and haven't begun to show any symptoms yet.
The incubation period for MERS is usually about five days but it's been known to take as long as 14 days to cause symptoms, so the doctors are taking the most cautious approach.
Middle East Respiratory Sydrome (MERS) virus was first seen in 2012 and most cases are linked to the Middle East, although it's now been seen in more than a dozen countries around the world. Many of those who are sick enough to show symptoms have had other conditions, such as cancer, diabetes or kidney disease.
It spreads from person to person, but usually only with close and prolonged contact. But Centers for Disease Control and Prevention experts and state health officials are testing health care workers and other close contacts of the patients, and will continue to test them for 14 days, just to be sure.
"It appears MERS picked the wrong hospital, the wrong state, and the wrong country to take hold," said Indiana state health commissioner Dr. William VanNess.
Officials are tracking down about 100 passengers from an airplane the patient traveled on and 10 bus passengers to make sure they don't have any symptoms. But experts say MERS has not been known to pass from casual contact such as sitting next to someone on public transport.
Health officials are releasing very little information about the patient but say he lives and works in Saudi Arabia. "He was working at a hospital in Saudi Arabia," said Dr. Daniel Feikin, CDC's medical epidemiologist at the hospital.
"He does not recall directly working with a patient who had MERS although he did work in a hospital that had cases of MERS."
He came to the U.S. on April 24 and went to the emergency department at the hospital on the 28th.'

'Roughly 12 million adults who visit U.S. doctors' offices and other outpatient settings, or one in 20, are misdiagnosed every year, a new study has found, and half of those errors could lead to serious harm.'
'In a cloning first, scientists create stem cells from adults
Scientists have moved a step closer to the goal of creating stem cells perfectly matched to a patient's DNA in order to treat diseases, they announced on Thursday, creating patient-specific cell lines out of the skin cells of two adult men.
The advance, described online in the journal Cell Stem Cell, is the first time researchers have achieved "therapeutic cloning" of adults. Technically called somatic-cell nuclear transfer, therapeutic cloning means producing embryonic cells genetically identical to a donor, usually for the purpose of using those cells to treat disease.
But nuclear transfer is also the first step in reproductive cloning, or producing a genetic duplicate of someone - a technique that has sparked controversy since the 1997 announcement that it was used to create Dolly, the clone of a ewe. In 2005, the United Nations called on countries to ban it, and the United States prohibits the use of federal funds for either reproductive or therapeutic cloning.
The new study was funded by a foundation and the South Korean government.
If confirmed by other labs, it could prove significant because many illnesses that might one day be treated with stem cells, such as heart failure and vision loss, primarily affect adults. Patient-specific stem cells would have to be created from older cells, not infant or fetal ones. That now looks possible, though far from easy: Out of 39 tries, the scientists created stem cells only once for each donor.'

When you first take a bite of sugary cereal, your taste receptors that respond to sweetness, found at the tip of your tongue, send a signal to the portion of your brain called the cerebral cortex.
This signal activates ‘the reward system’ and causes you to want to take another bite. Excessive activation of this reward system, Dr. Avena suggests, can cause ‘loss of control, craving and intolerance to sugar.’

The basic premise
The Carbohydrate Hypothesis, as attacked by Guyenet, looks basically like this:
Excessive amounts of carbohydrates (especially refined carbs / sugar) increases insulin and results in fat gain.
Guyenets argues in his post that carbs are not necessarily the cause of increased insulin, and insulin certainly do not result in gaining weight (maybe the opposite!). Basically he says that while low carb works, the theory to explain it is wrong.
However, as every doctor who has ever treated diabetics with insulin (and their patients) probably knows, injecting insulin certainly does tends to increase fat gain. And in untreated type 1 diabetics, with no insulin, weight plummets. Guyenet does not mention that.
Thin people usually have low insulin levels, obese people usually have high levels of insulin. Guyenet does not believe that is significant.
In short: Carbohydrates drives insulin, which drives fat.

‘Social symptoms in autistic children may be caused by hyper-connected neurons
The brains of children with autism show more connections than the brains of typically developing children do. What's more, the brains of individuals with the most severe social symptoms are also the most hyper-connected. The findings reported in two independent studies are challenge the prevailing notion in the field that autistic brains are lacking in neural connections.’
‘Autistic brains create more information at rest, study show
New research finds that the brains of autistic children generate more information at rest -- a 42 percent increase on average. The study offers a scientific explanation for the most typical characteristic of autism -- withdrawal into one's own inner world. The excess production of information may explain a child's detachment from their environment.’

Candies to soothe the throat date back to 1000 BC in Egypt's Twentieth Dynasty, when they were made from honey flavored with citrus, herbs, and spices. In the 19th century, physicians discovered morphine and heroin, which suppress coughing at its source—the brain. Popular formulations of that era included Smith Brothers Cough Drops, first advertised in 1852, and Luden's, created in 1879. Concern over the risk of opioid dependence led to the development of alternative medications
A lozenge (◊), often referred to as a diamond, is a form of rhombus. The definition of lozenge is not strictly fixed, and it is sometimes used simply as a synonym (from the French losange) for rhombus. Most often, though, lozenge refers to a thin rhombus—a rhombus with acute angles of 45°. The lozenge shape is often used in parquetry and as decoration on ceramics, silverware and textiles. It also features in heraldry and playing cards.
The lozenge motif dates as far back as the Neolithic and Paleolithic period in Eastern Europe and represents a sown field and female fertility. The ancient lozenge pattern often shows up in Diamond vault architecture, in traditional dress patterns of Slavic peoples, and in traditional Ukrainian embroidery. The lozenge pattern also appears extensively in Celtic art, art from the Ottoman Empire, and ancient Phrygian art.
The lozenge symbolism is one of the main female symbols in Berber carpets. Common Berber jewelry from the Aurès Mountains or Kabylie in Algeria also uses this pattern as a female fertility sign.
In 1658, the English philosopher Sir Thomas Browne published The Garden of Cyrus subtitled The Quincunciall Lozenge, or Network Plantations of the Ancients where he outlined the mystical interconnection of art, nature and the Universe. He suggested that ancient plantations used the quincunx pattern that revealed the "mystical mathematics of the city of Heaven" and proof of the wisdom of God.
Lozenges appear as symbols in ancient classic element systems, in amulets, and in religious symbolism. In a suit of playing cards, diamonds is in the shape of a lozenge.

Before 1980, peanut allergies were rarely mentioned in medical literature or the media, said Miranda Waggoner, a postdoctoral researcher at the Office of Population Research in the Woodrow Wilson School of Public and International Affairs. Her article on the subject, "Parsing the peanut panic: The social life of a contested food allergy epidemic," was published recently in the journal Social Science & Medicine.
Starting around 1990, articles in medical journals began discussing the seriousness of peanut allergies, Waggoner said. At the same time, advocacy groups were emerging to raise awareness of the issue. By the mid-1990s, newspapers were printing articles with headlines such as "Nut Allergy Girl's Terror; Girl Almost Dies from Peanut Allergy."
And the 21st century brought descriptions of peanut allergies — in medical journals and the media — as an epidemic.
For those with a peanut allergy, ingesting the legume can lead to anaphylactic shock and, if untreated, death. But the allergy is quite rare and it isn't clear whether it is becoming more common, Waggoner said.'

'Google's smart contact lens: what it does and how it works
Wearables may be on everyone's list as the major tech trend of the year, but Google just kicked it up to a whole new level. The company announced a project to make a smart contact lens on its official blog Thursday.
But the lens isn't going to be used to deliver your e-mail straight into your skull — at least not yet. This project is working to tackle one of the biggest health problems facing the country today: diabetes.
The soft contact lens that Google's is introducing — it's still just a prototype — houses a sensor between two layers of lenses that measures the glucose levels in tears. The lens also features a small — really small — antenna, capacitor and controller, so that the information gathered from the lens can move from your eye to a device where that data can be read and analyzed.
According to a short explanation of the technology provided by Google, the chip and sensors are mounted on a small plastic-like film. A tiny pinhole in the lens lets tear fluid seep over the glucose monitor to get regular readings. Right now, the company said, it can get a level reading once every second.'
Since when did Google get into the medical devices business?

'Nov. 1, 2013 — Despite current beliefs, sugar intake is not directly associated with nonalcoholic fatty liver disease, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association. Rather, high-calorie diets promote the progression of this serious form of liver disease.
Researchers conducted a double-blind study of healthy, but centrally overweight men to compare the effects of high intakes of two types of sugar, glucose and fructose, in two conditions -- weight-maintaining (moderate-calorie diet) and weight-gaining (high-calorie diet). In the weight-maintaining period, men on neither diet developed any significant changes to the liver. However, in the weight-gaining period, both diets produced equivalent features of nonalcoholic fatty liver disease, including steatosis (fatty liver) and elevated serum transaminase and triglycerides. These findings indicate that fructose and glucose have comparable effects on one's liver, and calorie intake is the factor responsible for the progression of liver disease.
"Based on the results of our study, recommending a low-fructose or low-glycemic diet to prevent nonalcoholic fatty liver disease is unjustified," said Professor Ian A. Macdonald, study author and faculty of medicine and health sciences, University of Nottingham, UK. "The best advice to give a patient is to maintain a healthy lifestyle with diet and exercise. Our study serves as a warning that even short changes in lifestyle can have profound impacts on your liver."'
