Week 31


A Carb Boost Without the Carbs

Athletes can improve their performance in intense bouts of exercise, lasting an hour or so, if they merely rinse their mouths with a carbohydrate solution. They don’t even have to swallow it.


A high-fat diet alters crucial aspects of brain dopamine signaling

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior, the foremost society for research into all aspects of eating and drinking behavior, finds that prolonged exposure to a high fat diet is correlated with changes in the brain chemical dopamine within the striatum, a critical component of the brain's reward system.


A Treatment for Multiple Sclerosis That Upsets Big Pharma

If angioplasty for MS catches on, who is going to buy all the toxic drugs now prescribed for the mysterious disease?


Acidic oceans - fish lose ability to smell danger

Fish face losing their ability to smell danger as the oceans grow more acidic, new research has revealed.


Adiposity hormone, leptin, regulates food intake by influencing learning and memory

This research study finds that the hormone leptin reduces food intake, in part, by activating the hippocampus, an area of the brain that controls learning and memory function. Researchers found that when leptin was delivered directly to the hippocampus in rats, the animals consumed less food and lost body weight. Leptin delivered to this region of the brain also impaired the ability of the animals to learn about the spatial location of food.


After 40 Years, NIH-Supported Researchers Identify Possible New Treatment for Severe Vasculitis

Investigators have made a major advance in treating people with a severe form of vasculitis, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, a rare but devastating disease of blood vessels. In a six-month study, a new treatment strategy provided the same benefits as the current standard of care used for more than 40 years but required less frequent treatments. Early results also suggest that patients with disease relapses—typically recurrences of fever, fatigue, kidney damage, or bleeding in the lungs—respond better to the new regimen. The study, which appears online in the New England Journal of Medicine, was led by John Stone, M.D., M.P.H., of Massachusetts General Hospital, Boston, and Ulrich Specks, M.D., of the Mayo Clinic, Rochester, Minn. It was conducted by the Immune Tolerance Network (ITN). The ITN is an international consortium supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and the Juvenile Diabetes Research Foundation International. Genentech Inc., of South San Francisco, Calif., and Biogen Idec Inc., of Weston, Mass., provided additional funding for the study.

Americans turn cold shoulder to sunscreen

Even as summer temperatures soar, Americans are turning a cold shoulder to sunscreen, according to a poll released on Friday.


An Optimal Diet Starts with a High-Protein Breakfast

A quality, high-protein diet – one that begins at breakfast – is critical for maintaining muscle mass, curbing hunger, reducing abdominal fat, and preventing and slowing the progression of age-related bone and muscle loss. These findings were presented during a panel presentation at the 2010 IFT Annual Meeting and Food Expo®. While humans maintain the ability to build muscle at any age, the effects of insufficient protein increase substantially in older adults, often leading to muscle and bone conditions such as sarcopenia (the degenerative loss of muscle mass) and osteoporosis, said Douglas Paddon-Jones, Ph.D., associate professor, physical therapy and internal medicine, the University of Texas Medical Branch.


Anti-cancer effects of broccoli ingredient explained

Light has been cast on the interaction between broccoli consumption and reduced prostate cancer risk. Researchers writing in BioMed Central's open-access journal Molecular Cancer have found that sulforaphane, a chemical found in broccoli, interacts with cells lacking a gene called PTEN to reduce the chances of prostate cancer developing.


Anti-obesity effects of soy in a rat model of menopause

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior, the foremost society for research into all aspects of eating and drinking behavior, finds that a diet rich in soy prevents weight gain in post-menopausal female rats.


Are Sleeping Pills Addictive?

These drugs can, however, be psychologically habit-forming. If the sleeping pill effectively promotes sleep but is stopped suddenly, for instance, some people may show signs of psychological dependence, with the desire to want to keep taking them.

Australian study shows supportive community programs can prevent women from gaining weight

A simple community program developed and researched by the Jean Hailes Foundation for Women's Health in Australia has been shown to be effective in preventing excess weight gain commonly experienced by young mothers. Published in the British Medical Journal online at bmj.com this is the first randomized controlled intervention in women that we're aware of to prevent weight gain rather than treat overweight.


Autism Recovery - Don't Ask, Don't Tell

It’s happening all over - Kids use nutrition, special diets, and biomedical tools for autism. They make stunning progress. They blow through ABA trials instead of trudging along; they approach peers on a busy playground; they look their parents in the eyes and start talking; they function at school, and teachers’ jaws drop. Wow!


Avastin fails to slow breast cancer

Federal health scientists said Friday that followup studies of a Roche breast cancer drug show it failed to slow tumour growth or extend patient lives, opening the door for a potential withdrawal in that indication.

Bayer loses 5th straight trial

Bayer AG lost its fifth straight trial over contaminated U.S. long-grain rice to a Louisiana farmer who claimed the company's carelessness with its genetically engineered seed caused exports to plunge.


Beet juice lowers blood pressure

The vegetable known as the beetroot in Great Britain (and usually called the table beet, garden beet, red beet or just plain beet in the U.S.) has been studied in recent years for its health-building properties. For example, scientists have found it is rich in the nutrient betaine, which reduces the blood concentration of homocycsteine, a substance linked to heart disease and stroke. Now a study just published in the American Heart Association's Hypertension journal concludes drinking beet juice lowers high blood pressure quickly and effectively -- and could be a natural approach to helping prevent cardiovascular problems.


Behavior problems in school linked to 2 types of families

Contrary to Leo Tolstoy's famous observation that "happy families are all alike; every unhappy family is unhappy in its own way," a new psychology study confirms that unhappy families, in fact, are unhappy in two distinct ways. And these dual patterns of unhealthy family relationships lead to a host of specific difficulties for children during their early school years.


Big Oil Makes War on the Planet

Our addiction to oil is now blowing back on the civilization that can't do without its gushers and can't quite bring itself to imagine a real transition to alternative energies.


Biologists identify a new clue into cellular aging

The ability to combat some age-related diseases, such as cancer and diabetes, may rest with scientists unlocking clues about the molecular and cellular processes governing aging. The underlying theory is that if the healthy portion of an individual's life span can be extended, it may delay the onset of certain age-related diseases. In the search to understand these molecular processes, researchers at the University of Massachusetts Medical School have uncovered an important new DAF-16 isoform - DAF-16d/f - that collaborates with other DAF-16 protein isoforms to regulate longevity.

BP Photoshopped Fake Crisis Command Center for Website

Scott Dean, a spokesman for BP, said that there was nothing sinister in the photo alteration and provided the original unaltered version. He said that a photographer working for the company had inserted the three images in spots where the video screens were blank.


BP's oil spill caused by fed's dangerous culture of permissiveness'

The Bush administration focused from its earliest days on ramping up domestic oil and gas production, charged House Democrats, but at the same time allowed the industry a "dangerous culture of permissiveness" that culminated in the April 20 explosion of the Deepwater Horizon in the Gulf of Mexico.


Brain responses of obese individuals are more weakly linked to feelings of hunger

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior, the foremost society for research into all aspects of eating and drinking behavior, finds that that feelings of hunger have less influence on how the brain responds to the smell and taste of food in overweight than healthy weight individuals.


Brain size associated with longevity

Mammals with larger brains in relation to body size tend to live longer. This is the conclusion reached by researchers at the Centre for Ecological Research and Forestry Applications, affiliated to Universitat Autonoma de Barcelona, after having analyzed almost 500 mammal species and obtaining new data on the relation between brain size and lifespan.

Calcium from salmon and cod bone is well absorbed in young healthy men:a double-blinded randomised crossover design

Mean Ca absorption (+/- SEE) from the three different Ca sources were 21.9 +/- 1.7%, 22.5 +/- 1.7% and 27.4 +/- 1.8% for cod bones, salmon bones, and control (CaCO3), respectively. Conclusion: We conclude that bones from Atlantic salmon and Atlantic cod are suitable as natural Ca sources in e.g. functional foods or as supplements.


Carbohydrates Are Wonderful

Replace saturated fat with high-glycemic carbohydrates, and the risk of heart disease goes up. Perhaps the committee will at least acknowledge that we should be avoiding high-glycemic, refined carbohydrates. Let’s see what they have to say on the matter:

Children with Autism Unimpaired by Non-Varied Diet

But a new study conducted in the UK has determined that despite their pickiness, they physically develop “normally” when compared to autism free children.


Chronic and acute effects of walnuts on antioxidant capacity and nutritional status in humans

Walnut consumption did not significantly change the plasma antioxidant capacity of healthy, well-nourished older adults in this pilot study. However, improvements in linoleic acid and pyridoxal phosphate were observed with chronic consumption, while total plasma thiols were enhanced acutely. Future studies investigating the antioxidant effects of walnuts in humans are warranted, but should include either a larger sample size or a controlled feeding intervention.


Circadian rhythms - their role and dysfunction in affective disorders

Circadian (daily) rhythms are found in all functions – e.g. performance, mood, endocrine rhythms, behaviour, sleep timing. The biological clocks that control circadian rhythms are based on a genetic programme of interacting molecules in cells throughout the body, coordinated by a ´master clock´ in the brain and synchronised by external cues, mainly light. Failure to adapt to environmental and societal cues leads to misalignment of the internal biological clocks, and is particularly evident with shift work and jet lag. This temporal dysregulation comes with enhanced risk of errors and accidents, loss of productivity, and health risks such as increased propensity for cancer, depression, sleep disturbances, gastrointestinal, metabolic and cardiovascular disorders, decreased immune responses and life span.


Closer to a treatment for autism

Rubicon winner Dalila Pinto discovered a copying error in the DNA of trial subjects who suffered from autism or a similar condition. Some segments of their DNA were copied either once too often or missed out of the copying process. This is a highly promising result from the world's largest investigation into autism. The top journal Nature placed the results online on 9 June. About one child in every 110 suffers from autism or a condition on the autistic spectrum: PDD-NOS or Asperger's syndrome. The condition only manifests itself at the age of about 2 or 3, and there is no cure. Dalila Pinto and her co-researchers on the international 'Autism genome project' investigated the DNA of nearly 1000 autism patients. They discovered a completely new set of 'broken' genes that might cause autism, including some genes that might enable early diagnosis. The errors in the DNA are the result of incorrect copying. A new copy of the DNA is required for every new cell. Your body therefore continually produces new DNA copies. This goes wrong once in a while for everyone. A part of the DNA is then copied either once too often or else missed out of the copying process. This can cause genetic short-circuits. The researchers discovered that this type of copying error occurs much more often in patients with autism.


Combat injuries may cause epilepsy years later

Soldiers may develop epilepsy from a head injury as many as 30 years down the road, hints a new study of Vietnam veterans.

Agricultural Research Service chemist Thomas Wang, who specializes in cancer prevention research, has reported evidence that for some dietary compounds, length of exposure over time may be key to whether or not ingestion leads to a beneficial, or detrimental, effect.


Conflicted meat-eaters deny that meat-animals have the capacity to suffer

A new study from the University of Kent has provided direct evidence that people who wish to escape the ‘meat paradox’ i.e. simultaneously disliking hurting animals and enjoying eating meat, may do so by denying that the animal they ate had the capacity to suffer. By engaging in denial, those participating in the study also reported a reduced range of animals to which they felt obligated to show moral concern. These ranged from dogs and chimps to snails and fish. The study, the results of which are published in the August issue of Appetite, was conducted by Dr Steve Loughnan, Research Associate at the University’s School of Psychology, and colleagues in Australia.


Could our minds be tricked into satisfying our stomachs?

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior, the foremost society for research into all aspects of eating and drinking behavior, suggests that the key to losing weight could lie in manipulating our beliefs about how filling we think food will be before we eat it, suggesting that portion control is all a matter of perception.

People in an Alabama city who had higher levels of the chemicals known as PCBs in their bodies were much more likely to have high blood pressure, a recent study found, but it's not clear if the PCBs actually caused their hypertension.


Cow's milk does a baby good

Professor Yitzhak Katz of Tel Aviv University's Sackler Faculty of Medicine has found that babies who are fed cow milk protein early, in the form of infant formula, seem to be protected from developing an allergy to the same protein later in life. "Women who regularly (daily) introduced their babies to cow milk protein early, before 15 days of life, almost completely eliminated the incidence of allergy to cow milk protein in their babies," he reports.


CWRU Dental Researchers Discover Human Beta Defensins-3 Ignite in Oral Cancer Growth

detecting oral cancer in its earliest stages can save the lives of the nearly 40,500 people diagnosed annually. But early detection has been difficult. Case Western Reserve University School of Dental Medicine researchers discovered a biomarker, called human beta defensin-3 (hBD-3), which may serve as an early warning. The defensin is present in all oral cancers and associated with the early stages of oral cancer.

Findings overturn old theory of phytoplankton growth, raise concerns for ocean productivity

A new study concludes that an old, fundamental and widely accepted theory of how and why phytoplankton bloom in the oceans is incorrect. The findings challenge more than 50 years of conventional wisdom about the growth of phytoplankton, which are the ultimate basis for almost all ocean life and major fisheries. And they also raise concerns that global warming, rather than stimulating ocean productivity, may actually curtail it in some places.

Gene Therapy Breakthrough Heralds Treatment for ?-thalassemia

Italian scientists pioneering a new gene transfer treatment for the blood disorder ?-thalassemia have successfully completed preclinical trials, claiming they can correct the lack of beta-globin (ß-globin) in patients' blood cells which causes the disease. The research, published in EMBO Molecular Medicine, reveals how gene therapy may represent a safe alternative to current cures that are limited to a minority of patients. The disorder ?-thalassemia, also known as Cooley's anemia, is caused when a patient cannot produce enough of the ß-globin component of haemoglobin, the protein used by red blood cells to carry oxygen around the body. The lack of ß-globin causes life threatening anemia, leading to severe damage of the body's major organs. The condition is most commonly found in Mediterranean, Middle Eastern and Asian populations. "Currently treatments are limited to lifelong regular blood transfusions, and iron chelation to prevent fatal iron overload. The alternative is bone marrow transplantation, an option open to less than 25% of patients," said Dr Giuliana Ferrari from the San Raffaele Telethon Institute for Gene Therapy in Milan. "Our research has focused on gene therapy: by transplanting genetically corrected stem cells we can restore haemoglobin production and overcome the disorder."


Genes decide who wins in the body's battle against cancer

Researchers funded by the Medical Research Council have discovered for the first time that two proteins called Mahjong and Lgl could be star players in helping to identify how the body's own cells fight back against cancer cells. This discovery, publishing today in the online, open-access journal PLoS Biology, could lead to future treatments to make our healthy cells better-equipped to attack cancer cells, an entirely new concept for cancer research.


Genes' role in autism a complicated connection

Though scientists know genetic factors play a part in the array of autism disorders, the vast number of genes involved, plus possible environmental considerations, make narrowing the cause a vastly difficult goal.

High cholesterol in children may drop naturally on its own over time

A new study published in the journal Pediatrics has found that children with high cholesterol may not need drug treatments to bring them back to normal, healthy levels. Children who tested with high cholesterol levels initially in the study eventually had their levels taper off, indicating that the process may occur naturally over time, without the need for drugs.


History Haunts BP Communications Efforts

Images of thick brown oil floating atop Gulf of Mexico waters make BP’s attempts to reassure the public a hard sell as cleanup of the oil spill continues. The company’s prime-time commercials tout crews working around the clock, with promises to be in the Gulf as long as it takes to restore beaches and fisheries. But a University of Kentucky crisis communications expert says the company’s ongoing communications efforts are haunted by several mistakes made early in the disaster, and a history of cost-cutting measures that put profit above safety.


HIV vaccines may induce HIV antibodies in trial participants, can cause false-positive test result

During trials of preventive HIV vaccines, trial participants may develop HIV-related antibody responses that could lead to a positive HIV test by routine antibody detection methods (called vaccine-induced seropositivity/reactivity [VISP]), and the potential for false-positive test results and an incorrect HIV diagnosis, according to a study in the July 21 issue of JAMA, a theme issue on HIV/AIDS.

How Memory Is Disrupted in People with Disease Linked to Learning Disabilities

Imagine if your brain lost its working memory — the ability to hold and manipulate information in your mind's eye. That's the plight faced by millions of people with neurofibromatosis type 1, or NF1. The genetic condition affects one in 3,500 people and is the most common cause of learning disabilities. Now a UCLA research team has uncovered new clues about how NF1 disrupts working memory. Published in the July 12 online edition of Proceedings of the National Academy of Sciences, the findings suggest a potential drug target for correcting NF1-related learning disabilities.

Iced Tea May Raise Your Risk of Painful Kidney Stones, Urologist Warns

Iced tea contains high concentrations of oxalate, one of the key chemicals that lead to the formation of kidney stones, a common disorder of the urinary tract that affects about 10 percent of the population in the United States. Though hot tea also contains oxalate, it isn’t as easy to consume a quantity large enough amount to encourage the formation of stones. “For many people, iced tea is potentially one of the worst things they can drink,” said Dr. John Milner, assistant professor, Department of Urology, Loyola University Chicago Stritch School of Medicine, Maywood, Ill. “For people who have a tendency to form kidney stones, it’s definitely one of the worst things you can drink.”


Improving clinical use of stem cells to repair heart damage

Presenting at the UK National Stem Cell Network annual science conference today (13 July), Professor Michael Schneider describes a new approach to treating heart attack and cardiomyopathy using stem cells. Professor Schneider, British Heart Foundation Professor at Imperial College London, said "Recent clinical trials using stem cells to treat heart damage havebeen successful in terms of safety but unfortunately the bone marrow stem cells used tend to give only a small improvement in how well the heart is pumping. "We really want to use stem cells from the patients themselves that we know cangive rise to beating heart cells and these are not found in bone marrow. The good news is that we're now finding ways to identify and purify such cells." Around 1000 patients have been treated in approximately 20 trials worldwide,mostly using bone marrow stem cells or derivatives of bone marrow cells to repair damage caused by heart attack. There has also been a significant body of work looking at ways of producing beating heart cells from stem cells. The best proven approaches to creating new beating heart cells are using embryonic stemcells, induced pluripotent cells and heart-derived stem cells.


Increases in Leptin May Promote Colorectal Cancer

While researchers have known that obesity increases the risk for the development of colon cancer, the underlying molecular mechanisms have remained unclear.


Insight into why low calorie diet can extend lifespan -- even if adopted later in life

New research being presented this week is giving scientists new insight into why a restricted diet can lead to a longer lifespan and reduced incidence of age-related diseases for a wide variety of animals. Scientists have known for some time that a restricted diet can extend the lifespan of certain animals but this work shows how it affects aging mechanisms -- and significantly has also shown that the effects occur even if the restricted diet is adopted later in life.

Painters at bladder cancer risk

PAINTERS are at a significantly increased risk of developing bladder cancer, claims a new study.


Part of the brain that tracks limbs in space discovered

When a mosquito lands on your hand, you can rapidly and effortlessly make a movement of the other hand to brush it away, even in darkness. But performing this seemingly simple action involves a surprisingly complex coordination of different types of sensory information in order for your brain to construct a constantly updated 'map' of the body in space. Now, scientists from UCL (University College London) and Barcelona (Pompeu Fabra University, ICREA and University of Barcelona) have identified an area of the human brain called the parietal cortex that constructs this body model from the combination of tactile information from your skin (for example, where the mosquito is on your hand) with "proprioceptive" information about the position of your hand relative to your body.

Redundant genetic instructions in 'junk DNA' support healthy development

New findings from a Princeton-led team of researchers suggest that repeated instructional regions in the flies' DNA may contribute to normal development under less-than-ideal growth conditions by making sure that genes are turned on and off at the appropriate times. If similar regions are found in humans, they may hold important clues to understanding developmental disorders.


Research Links Phthalates in Plastics with Inflammation in At-Risk Babies

Researchers at the University of Medicine and Dentistry of New Jersey (UMDNJ) have identified a direct link between phthalates, the substances that make plastics more pliable and durable, and inflammation in newborns – and are encouraging more limited use of the plasticizers. Their paper, “Inflammatory Effects of Phthalates in Neonatal Neutrophils,” appears in the August 2010 edition of the journal Pediatric Research. Previous studies have shown that premature babies are exposed to extraordinarily high concentrations of phthalates because of long-term exposure to phthalates in plastic medical equipment used during neonatal intensive care. These include multiple types of tubing, such as breathing tubes, feeding tubes, intravenous tubes, that these babies rely upon to survive. However, concern arises regarding the impact of that exposure on babies’ health.


Researchers find mice cages alter brains

Researchers at the University of Colorado's Anschutz Medical Campus have found the brains of mice used in laboratories worldwide can be profoundly affected by the type of cage they are kept in, a breakthrough that may require scientists to reevaluate the way they conduct future experiments. "We assume that mice used in laboratories are all the same, but they are not," said Diego Restrepo, director of the Neuroscience Program and professor of cell and developmental biology whose paper on the subject was published Tuesday, June 29. "When you change the cages you change the brains and that affects the outcomes of research." Mice are the chief research mammals in the world today with some of the most promising cancer, genetic and neuroscience breakthroughs riding on the rodents. Researchers from different universities rely on careful comparison of experimental results for their discoveries; but Restrepo has found that some of these comparisons may not be trustworthy.

Why Is the Obama Administration Parroting Monsanto Talking Points?

When key government officials start touting the need for biotechnology there's reason to be concerned. Roger Beachy, the Chief Scientist of the US Department of Agriculture (USDA), recently told Smartplanet.com that biotechnology is needed to maximize food production and reduce the use of agrochemicals. "With a greater number of people," he said, "we're going to have to have more crop per acre. If we don't, we'll have to expand [agriculture] to our parks, forests, and golf courses." And at first it might seem strange to hear a top government official parroting talking points from Monsanto's Corporate Responsibility page ... until you read his resume, that is. His last job before joining the USDA was as founding president of the Donald Danforth Plant Science Center, a non-profit research institute co-founded by Monsanto and the Danforth Foundation.
