Toxoplasmosis: The Strain Explains Severity of Infection - ScienceDaily (Mar. 14, 2011) — Providing clues into why the severity of a common parasitic infection can vary greatly from person to person, a new Johns Hopkins study shows that each one of three strains of the cat-borne parasite Toxoplasma gondii sets off a unique reaction in the nerve cells it invades.
Past research suggests that the parasite, estimated to infect 25 percent of people worldwide, can trigger or exacerbate psychotic symptoms and schizophrenia in genetically predisposed people.
The findings of the new study, published in the March issue of the journal Infection and Immunity, help explain why the infection causes serious disease in some but not in others and clarify its role in psychiatric disorders, the researchers say. - http://www.sciencedaily.com/releases/2011/03/110314163600.htm

Why Coffee Protects Against Diabetes
(Jan. 12, 2011) - (ScienceDaily) - [Excerpt]:
Coffee, that morning elixir, may give us an early jump-start to the day
but numerous studies have shown that it also may be protective against type 2 diabetes.
Yet no one has really understood why.
Now, researchers at UCLA have discovered a possible molecular mechanism behind coffee's protective effect.
A protein called sex hormone-binding globulin (SHBG)
regulates the biological activity of the body's sex hormones, testosterone and estrogen,
which have long been thought to play a role in the development of type 2 diabetes.
And coffee consumption, it turns out, increases plasma levels of SHBG.

Cannabis May Influence Onset of Psychosis
(February 7, 2011 - Scientific American)
Research to be published this summer finds that the use of cannabis
is associated with the early onset of psychosis.
Christie Nicholson reports
Pot is one of those drugs that appears to maintain a fairly good rep, despite its growing bad rep.
Consider this research that will be published this June in the Archives of General Psychiatry.
This particular study found that marijuana use is associated with early development of psychosis.
Scientists analyzed 83 studies involving over 8,000 subjects
who used pot and over 14,000 subjects who did not.
They compared the age of onset for psychosis between these groups.
And they found that those who used cannabis developed psychosis
nearly three years younger than those who did not use any pot.
The researchers proposed some theories behind the pattern.
One that cannabis use is a causal factor for schizophrenia,
or that it precipitates psychosis in vulnerable people.
They also theorize that cannabis might simply exacerbate symptoms of schizophrenia.
Or the link could come from the other direction of course,
those suffering from schizophrenia may be more likely to use pot.
The evidence here suggests that limiting marijuana use could delay
or even prevent some cases of psychosis.
And timing is important,
since earlier onset of schizophrenia is linked to a worse prognosis overall.

Common Insecticide Used in Homes Associated With Delayed Mental Development of Young Children - (ScienceDaily - Feb. 10, 2011) - When the EPA phased out the widespread residential use of chlorpyrifos and other organophosphorus (OP) insecticides in 2000-2001 because of risks to child neurodevelopment, these compounds were largely replaced with pyrethroid insecticides. But the safety of these replacement insecticides remained unclear, as they had never been evaluated for long-term neurotoxic effects after low-level exposure. In the first study to examine the effects of these compounds on humans and the first evaluation of their potential toxicity to the developing fetal brain, scientists of the Columbia Center for Children's Environmental Health at Columbia University's Mailman School of Public Health found a significant association between piperonyl butoxide (PBO), a common additive in pyrethroid formulations, measured in personal air collected during the third trimester of pregnancy, and delayed mental development at 36 months.

US study links pesticides to Parkinson's disease
(Fri., Feb 11, 2011) - WASHINGTON (AFP)
US researchers said Friday they have found that people who used two specific varieties of pesticide
were 2.5 times as likely to develop Parkinson's disease.
The pesticides, paraquat and rotenone,
are not approved for house and garden use.
Previous research on animals has linked paraquat to Parkinson's disease,
so it is restricted to use by certified applicators.
Rotenone is approved only for use in killing invasive fish species.
"Rotenone directly inhibits the function of the mitochondria,
the structure responsible for making energy in the cell,"
said study co-author Freya Kamel,
a researcher at the National Institute of Environmental Health Sciences.
"Paraquat increases production of certain oxygen derivatives that may harm cellular structures.
People who used these pesticides or others with a similar mechanism of action
were more likely to develop Parkinson's disease."

New Study Finds No Cognitive Impairment Among Ecstasy Users - (ScienceDaily - Feb. 15, 2011) - The drug known as ecstasy has been used by 12 million people in the United States alone and millions more worldwide. Past research has suggested that ecstasy users perform worse than nonusers on some tests of mental ability. But there are concerns that the methods used to conduct that research were flawed, and the experiments overstated the cognitive differences between ecstasy users and nonusers.
In response to those concerns, a team of researchers has conducted one of the largest studies ever undertaken to re-examine the cognitive effects of ecstasy, funded by a $1.8 million grant from the National Institute on Drug Abuse (NIDA) and published in the journal Addiction. The study was specifically designed to minimize the methodological limitations of earlier research.
In contrast to many prior studies, ecstasy users in the new study showed no signs of cognitive impairment attributable to drug use: ecstasy use did not decrease mental ability. - http://www.sciencedaily.com/releases/2011/02/110215081736.htm

NY Times Report: Fracked Water Thousands of Times More Dangerous Than They're Telling Us
(February 28, 2011 - By Steven D. | Sourced from Booman Tribune) - http://mcaf.ee/b5f7d
Good old hydrofracking. You know about it right? It's the method to produce natural gas by fracturing rock formations with millions of gallons of water and toxic chemicals. It's been contaminating groundwater in the Western US for many years and now it is being pursued with a vengeance in the East, particularity with respect to the Marcellus Shale formation that extends across Pennsylvania and New York.
Everyone in the know has warned us for years that hydrofracking was highly dangerous to sources of groundwater used for human consumption. But only now are we being told how much worse is that contamination of our water supplies. So bad it will make you ill after you read this investigative report from the NY Times:
With hydrofracking, a well can produce over a million gallons of wastewater that is often laced with highly corrosive salts, carcinogens like benzene and radioactive elements like radium, all of which can occur naturally thousands of feet underground. Other carcinogenic materials can be added to the wastewater by the chemicals used in the hydrofracking itself.
While the existence of the toxic wastes has been reported, thousands of internal documents obtained by The New York Times from the Environmental Protection Agency, state regulators and drillers show that the dangers to the environment and health are greater than previously understood.
The documents reveal that the wastewater, which is sometimes hauled to sewage plants not designed to treat it and then discharged into rivers that supply drinking water, contains radioactivity at levels higher than previously known, and far higher than the level that federal regulators say is safe for these treatment plants to handle.

Cooking tomatoes increases the potency of the disease-fighting nutrient lycopene
Eating tomatoes can help reduce the risk of cancer, osteoporosis and cardiovascular disease, scientists have revealed.
Not only that but cooked or processed tomatoes are actually better for you than raw ones.
U.S researchers found the juicy vegetable is the biggest source of powerful antioxidant dietary lycopene, and unlike other fruit and vegetables it has greater potency after it is cooked.

Marijuana should be legalized, regulated and taxed. The push to repeal federal prohibition should come from the states, and it should begin with the state of Washington.
… Some drugs have such horrible effects on the human body that the costs of prohibition may be worth it. Not marijuana. This state’s experience with medical marijuana and Seattle’s tolerance policy suggest that with cannabis, legalization will work — and surprisingly well.

Do genes make people evil? - (March 8, 2011 - Scientific American) - By Daniel Lametti, a neuroscientist at McGill University
Since the 1960s psychologists have found that children who were abused and neglected are more likely to commit crimes later in life. Even so, researchers noted that most youngsters who are mistreated do not grow up to be criminals. Now our genes come into the picture.
A 2002 study found that a particular variation of a gene predicted antisocial behavior in men who were mistreated as children. The gene controls whether we produce an enzyme called monoamine oxidase A (MAOA), which at low levels has been linked to aggression in mice. The researchers found that boys who were neglected and who possessed a variation of the gene that produced low levels of MAOA were more likely to develop antisocial personality disorder, commit crimes and grow up to have a violent disposition. But those living in a similar environment who produced more of the enzyme rarely developed these problems.
Psychopaths are arguably the evilest of the evildoers. A study published in August 2010 looked at psychopathic tendencies in teenagers with low socioeconomic resources. The researchers found that adolescents who had a variation of another gene, which contributes to how quickly serotonin is recycled in the brain and which has been linked to hostile behavior in children, were more likely to exhibit signs of psychopathy.
These two recent findings provide strong evidence that evil behavior—mass murder, armed robbery, and perhaps even newspaper theft—might be caused by the right set of genes interacting with the wrong environment. - http://www.scientificamerican.com/article.cfm?id=do-genes-make-people-evil

Memory researchers have long debated whether there are two or three layers and what the capacity and function of each layer is.In a paper in the March issue of the Journal of Cognitive Psychology, researchers found that short-term memory is made up of three areas: a core focusing on one active item, a surrounding area holding at least three more active items, and a wider region containing passive items that have been tagged for later retrieval or "put on the back burner." But more importantly, they found that the core region, called the focus of attention, has three roles -- not two as proposed by previous researchers. First, this core focus directs attention to the correct item, which is affected by predictability of input pattern. Then it retrieves the item and subsequently, when needed, updates it. - http://mcaf.ee/92815
Sunlight Can Influence the Breakdown of Medicines in the Body - ScienceDaily (Mar. 9, 2011) — A study from the Swedish medical university Karolinska Institutet has shown that the body's ability to break down medicines may be closely related to exposure to sunlight, and thus may vary with the seasons. The findings offer a completely new model to explain individual differences in the effects of drugs, and how the surroundings can influence the body's ability to deal with toxins. - http://www.sciencedaily.com/releases/2011/03/110309073938.htm
As We Sleep, Speedy Brain Waves Boost Our Ability to Learn - ScienceDaily (Mar. 10, 2011) — Scientists have long puzzled over the many hours we spend in light, dreamless slumber. But a new study from the University of California, Berkeley, suggests we're busy recharging our brain's learning capacity during this traditionally undervalued phase of sleep, which can take up half the night.
UC Berkeley researchers have found compelling evidence that bursts of brain waves known as "sleep spindles" may be networking between key regions of the brain to clear a path to learning. These electrical impulses help to shift fact-based memories from the brain's hippocampus -- which has limited storage space -- to the prefrontal cortex's "hard drive," thus freeing up the hippocampus to take in fresh data. Spindles are fast pulses of electricity generated during non-REM sleep, and they can occur up to 1,000 times a night.
"All these pieces of the puzzle tell a consistent and compelling story -- that sleep spindles predict learning refreshment," said Matthew Walker, associate professor of psychology and neuroscience at UC Berkeley and senior author of the study to be published March 8 in the journal Current Biology. - http://www.sciencedaily.com/releases/2011/03/110308124748.htm

Adults With Attention Deficit Hyperactivity Disorder Score High in Creativity - ScienceDaily (Mar. 11, 2011) — Young adults with attention deficit hyperactivity disorder showed more creativity compared with those who did not have ADHD, a new study shows.
Researchers at the University of Michigan and Eckerd College also found that ADHD individuals preferred different thinking styles. They like generating ideas, but are not good about completing the tasks.
Lead author Holly White, an assistant professor of psychology at Eckerd, and Priti Shah, an associate professor at U-M, replicated their study from 2006, and those results found that ADHD individuals show better performance on standardized creativity tests.
Previous research regarding individuals with ADHD focused on laboratory measures of creativity.
"We knew that ADHD individuals did better at laboratory measures of divergent thinking, but we didn't know if that would translate to real-life achievement. The current study suggests that it does," Shah said.
Divergent thinking involves generating several possible solutions to a problem. - http://mcaf.ee/79534

What It's Like Living in Our Nuclear Sacrifice Zone - (March 21, 2011 - The Phoenix Sun / By Valerie Brown - http://tinyurl.com/65f48e8 ) -
The official focus on high short-term doses is deceptive. Emerging science suggests that low doses of radiation exposure can have numerous long-term effects, possibly passed from one generation to the next. And almost all the discussion about – and the scientific research on – radiation exposure focuses on cancers. There are certainly many cancers that radiation can induce in addition to thyroid cancer, from breast and prostate cancer to various leukemias. These cancers are thought to result from energetic particles striking DNA, breaking strands, and interfering with gene replication. Faulty genes lead to faulty cells, is the thinking. But there may also be epigenetic effects – that is, changes in the way normal genes are organized and allowed to function – and these may result in disorders other than cancer, such as thyroid diseases, autoimmune problems, and hormones gone haywire.
To make matters worse, how old you are when you’re exposed makes a big difference too. Prenatal insults including chemical and radiation exposure can create epigenetic patterns of gene expression that will stay with you forever, even if your actual genes are undamaged. And it can take 50 or more years for the timer set in the womb to trip the fuse and trigger a full-blown disease.
In a 2009 review article, Canadian researchers Carmel Mothersill and Colin Seymour of McMaster University nicely expressed the emerging state of knowledge about the effects of low-level radiation exposure:
“Our understanding of the biological effects of low dose exposure has undergone a major paradigm shift….[W]e understand, at least in part, some of the mechanisms which drive low dose effects and which perpetuate these not only in the exposed organism but also in its progeny and in certain cases, its kin. This means that previously held views about safe doses or lack of harmful effects cannot be sustained.”

Federal agency proclaims medical use for marijuana - (3-24-11 - By Kyle Daly - The Washington Independent) - As federal battles over medical marijuana across the country heat up, a statement from one federal agency may be a huge asset for medical marijuana dispensaries that have been targeted by the various arms of the U.S. Department of Justice and the IRS.
The National Cancer Institute (NCI) is a division of the National Institute of Health, which is itself one of the 11 component agencies that make up the U.S. Department of Health and Human Services.

Group warns EPA ready to increase radioactive release guidelines - (April 3, 2011 - by Anne Paine - The Tennessean) - ( http://mcaf.ee/eb82a ) - The EPA is preparing to dramatically increase permissible radioactive releases in drinking water, food and soil after “radiological incidents,” according to Public Employees for Environmental Responsibility.
What is termed a guidance that EPA is considering - as opposed to a regulation - does not require public airing before it’s decided upon.
EPA officials contacted today in the Atlanta and D.C. offices had no response on the issue as of 6 p.m.
The radiation guides called Protective Action Guides or PAGs are protocols for responding to radiological events ranging from nuclear power-plant accidents to dirty bombs.
Drinking water, for example, would have a huge increase in allowable public exposure to radioactivity, the group says, that would include:
A nearly 1000-fold increase in strontium-90
A 3000 to 100,000-fold hike for iodine-131
An almost 25,000 rise for nickel-63
The new radiation guidance would also allow long-term cleanup standards thousands of times more lax than anything EPA has ever before accepted, permitting doses to the public that EPA itself estimates would cause a cancer in as much as every fourth person exposed, the group says.
These relaxed standards are opposed by public health professionals inside EPA, according to documents PEER said it obtained under the Freedom of Information Act.PEER is a national alliance of local state and federal resource professionals

Germs with Your Lemon Wedge? - (November 14, 2010 in Pharmacy Q&A) - Q. One of my co-workers always asks for a slice of lemon in his water. I shudder every time I see that piece of lemon floating in his glass but I don't have the nerve to tell him it's probably loaded with germs. Am I mistaken?
A. You are correct. Microbiologist Anne LaGrange Loving was served a Diet Coke with a slice of lemon she had not requested. She decided to check whether the lemon was likely to be contaminated.
She and her co-author surreptitiously swabbed 76 lemon slices served at 21 different restaurants, then cultured the results. Two-thirds of the lemon slices had bacteria on either the rind or the pulp (Journal of Environmental Health, Dec., 2007). Many of these germs have the potential to cause illness, although the study was not designed to discover if any patrons actually became sick.
You're not the only one to wonder about this. Another reader wrote: "I wish you would address the way water is served in restaurants. It frequently comes with a lemon floating in the water. Tests on lemons from various restaurants found fecal bacteria. They should ask whether you want lemon or not." We agree with that recommendation. - http://www.peoplespharmacy.com/2010/11/14/germs-with-your-lemon-wedge/

Nanoparticles With Honeycomb Cavities Containing Drugs Blast Cancer Cells - ScienceDaily (Apr. 18, 2011) — Melding nanotechnology and medical research, Sandia National Laboratories, the University of New Mexico, and the UNM Cancer Research and Treatment Center have produced an effective strategy that uses nanoparticles to blast cancerous cells with a mélange of killer drugs.
In the cover article of the May issue of Nature Materials, available online April 17 , the researchers describe silica nanoparticles about 150 nanometers in diameter as honeycombed with cavities that can store large amounts and varieties of drugs.
"The enormous capacity of the nanoporous core, with its high surface area, combined with the improved targeting of an encapsulating lipid bilayer [called a liposome], permit a single 'protocell' loaded with a drug cocktail to kill a drug-resistant cancer cell," says Sandia researcher and UNM professor Jeff Brinker, the principal investigator. "That's a millionfold increase in efficiency over comparable methods employing liposomes alone -- without nanoparticles -- as drug carriers." - http://www.sciencedaily.com/releases/2011/04/110418114208.htm
Canola Oil Protects Against Colon Cancer, Study Suggests - ScienceDaily (Apr. 19, 2011) — A new study of canola oil finds that it reduces the size and incidence of colon tumors in laboratory animals, a South Dakota State University scientist says. The research suggests using canola oil in household cooking may protect against colon cancer development.
Distinguished professor Chandradhar Dwivedi, head of SDSU's Department of Pharmaceutical Sciences, led the study. He and his colleagues published their journal article on the topic, "Chemopreventive Effects of Dietary Canola Oil on Colon Cancer Development," in the February 2011 issue of the journal Nutrition and Cancer.
"This is the first time anyone has done work on the effect of canola oil in animals on colon cancer prevention. Canola oil was able to reduce the incidence of colon cancer in animals almost to one-third," Dwivedi said.
The study showed that canola oil inhibited the average number of tumors per rat by 58 percent compared to one of the other two control diets in the experiment, and inhibited the size of the tumors that occurred by 90 percent. - http://www.sciencedaily.com/releases/2011/04/110419185146.htm

What's Your Gut Type? Gut Bacteria Could Help With Diagnostics and Influence Treatments - ScienceDaily (Apr. 20, 2011) — In the future, when you walk into a doctor's surgery or hospital, you could be asked not just about your allergies and blood group, but also about your gut type. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and collaborators in the international MetaHIT consortium, have found that humans have three different gut types.
The study, published in Nature, also uncovers microbial genetic markers that are related to traits like age, gender and body-mass index. These bacterial genes could one day be used to help diagnose and predict outcomes for diseases like colo-rectal cancer, while information about a person's gut type could help inform treatment. - http://www.sciencedaily.com/releases/2011/04/110420143620.htm

Over Range of ADHD Behavior, Genes Major Force on Reading Achievement, Environment on Math - ScienceDaily (Apr. 22, 2011) — Humans are not born as blank slates for nature to write on. Neither are they behaving on genes alone. Research by Lee A. Thompson, chair of Case Western Reserve University's Psychological Sciences Department, and colleagues found that the link between Attention-Deficit/Hyperactivity Disorder (ADHD) and academic performance involves a complex interaction of genes and environment.
Genetic influence was found to be greater on reading than for math, while shared environment (e.g., the home and/or school environment the twins shared) influenced math more so than reading. The researchers don't know why.
Their study of twins, published in Psychological Science, Vol. 21, was the first to look simultaneously at the genetic and environmental influences on reading ability, mathematics ability, and the continuum of ADHD behavior. - http://www.sciencedaily.com/releases/2011/04/110422115846.htm

Mercury Converted to Its Most Toxic Form in Ocean Waters - ScienceDaily (Apr. 27, 2011) — University of Alberta-led research has confirmed that a relatively harmless inorganic form of mercury found worldwide in ocean water is transformed into a potent neurotoxin in the seawater itself.
After two years of testing water samples across the Arctic Ocean, the researchers found that relatively harmless inorganic mercury, released from human activities like industry and coal burning, undergoes a process called methylation and becomes deadly monomethylmercury.
Unlike inorganic mercury, monomethylmercury is bio-accumulative, meaning its toxic effects are amplified as it progresses through the food chain from small sea creatures to humans. The greatest exposure for humans to monomethylmercury is through seafood. The researchers believe the methylation process happens in oceans all over the world and that the conversion is carried out by microbial life forms in the ocean. - http://www.sciencedaily.com/releases/2011/04/110427131935.htm

In Harm's Way, But in the Dark - (Sunday, August 8, 1999 - by Joby Warrick, Washington Post Staff Writer) - PADUCAH, Ky. – Thousands of uranium workers were unwittingly exposed to plutonium and other highly radioactive metals here at a federally owned plant where contamination spread through work areas, locker rooms and even cafeterias, a Washington Post investigation has found.
Unsuspecting workers inhaled plutonium-laced dust brought into the plant for 23 years as part of a flawed government experiment to recycle used nuclear reactor fuel at the Paducah Gaseous Diffusion Plant, according to a review of court documents, plant records, and interviews with current and former workers. The government and its contractors did not inform workers about the hazards for decades, even as employees in the 1980s began to notice a string of cancers.
Radioactive contaminants from the plant spilled into ditches and eventually seeped into creeks, a state-owned wildlife area and private wells, documents show. Plant workers contend in sealed court documents that radioactive waste also was deliberately dumped into nearby fields, abandoned buildings and a landfill not licensed for hazardous waste.
The sprawling Kentucky plant on the Ohio River represents an unpublished chapter in the still-unfolding story of radioactive contamination and concealment in the chain of factories across the country that produced America's Cold War nuclear arsenal. - http://mcaf.ee/qsg2n
Tainted uranium, danger widely distributed - (6-24-01 - by Peter Eisler - USA TODAY) - For years, state investigators wondered why radioactive technetium-99 was turning up in drinking water wells near the old Mallinckrodt Chemical uranium fuel-making plant in Hematite, Mo. Now they think they have an answer: The plant was one of several in and around St. Louis where Mallinckrodt and its successors used thousands of tons of recycled uranium to fabricate metallic fuel rods for nuclear reactors. "We believe the contamination we're now seeing at the site is related to the (recycling) program," says Ron Kucera of the Missouri Department of Natural Resources. Plans to clean up extensive pollution from uranium wastes at Hematite are snagged by questions over who is responsible for the technetium. That element requires special disposal because it has a half-life of 213,000 years and moves easily into soil and water. Technetium wasn't expected at Hematite because it is produced only when uranium is irradiated in a nuclear reactor — and Hematite had no reactor. "The Department of Energy has resisted efforts to become involved because even though they may have some liability, they don't want to pay anything," Kucera says. The Hematite facility was part of a nationwide network of private and federally owned plants and labs that produced fuel and other components for the nearly 70,000 U.S. nuclear weapons built before production was phased out in the early 1990s. Many of them used recycled uranium. The recycling began at the dawn of the Cold War. Officials in the weapons program were seeking ways to reuse the costly uranium that was irradiated in nuclear reactors to make plutonium and other fissile explosives for bomb cores. - http://www.usatoday.com/news/poison/2001-06-25-hotnukes.htm

Living With a Smoker May Raise Blood Pressure in Boys - ScienceDaily (May 1, 2011) — Exposure to secondhand smoke, even at extremely low levels, is associated with increased blood pressure in boys, according to new research presented May 1, at the Pediatric Academic Societies (PAS) annual meeting in Denver.
Children with elevated blood pressure are at increased risk of having high blood pressure, or hypertension, as adults. Hypertension is associated with a higher risk of heart and kidney disease and is the third leading contributor to illness and death worldwide. Yet, knowledge of risks factors for elevated blood pressure among children is limited.
Studies in non-smoking adults have shown associations between both secondhand smoke and outdoor air pollution with increased blood pressure, but no research has looked at this relationship in children.
In this study, researchers analyzed data from four National Health and Nutrition Examination Surveys conducted from 1999-2006 by the Centers for Disease Control and Prevention. They assessed 6,421 youths' exposure to secondhand smoke from their own reports of whether they lived with a smoker and through participants' levels of cotinine, a substance produced when the body breaks down nicotine. Cotinine levels are considered the best marker of tobacco smoke exposure.
Results showed that boys ages 8 to 17 years old who were exposed to secondhand smoke had significantly higher systolic blood pressure than boys not exposed to tobacco smoke. - http://www.sciencedaily.com/releases/2011/05/110501183813.htm

A Screening Test for Cognitive Therapy? -
Predicting which patients may
benefit from treatment for depression
- Philadelphia, PA – 18 April
2011 - The scientific foundation of psychiatry is growing rapidly, yet it is a
branch of medicine distinctive for the relative absence of biological tests in
routine clinical practice.
The most effective treatments for depression, including cognitive therapy, are successful for only about half the patients to whom they are given. The ability to predict those individuals who would be most likely to benefit from such treatment would reduce individuals’ recovery times, eliminate the delivery of ineffective treatments, and reduce the high costs of care.
Recent work suggests that reasonable predictions can be made about which patients will respond to cognitive therapy if they are given a brain scan. Unfortunately, brain scans are too expensive, time-intensive, and fraught with technical challenges to use on a routine basis.
Now, researchers at the University of Pittsburgh and the University of Pennsylvania are reporting a potential alternative. Their findings are published in the current issue of Biological Psychiatry.
“We have shown that a quick, inexpensive, and easy to administer physiological measure, pupil dilation in response to emotional words, not only reflects activity in brain regions involved in depression and treatment response but can predict which patients are likely to respond to cognitive therapy,” explained Dr. Greg Siegle, corresponding author on the study.
“According to proverb, the eye is the mirror of the soul or, in this case, the brain. The essential finding of this study is that that activity in the brain's cortical emotion regulatory systems is strongly related to pupil size when people are viewing emotion-laden words,” commented Dr. John Krystal, Editor of Biological Psychiatry. “It is because of this relationship between eye and brain that pupil measurements predict the response to cognitive therapy.
Cognitive therapy is a type of psychotherapy designed to help individuals overcome difficulties by modifying negative or irrational thoughts and behavior, which, in turn, can improve mood and reduce stress. It is usually completed in weekly sessions, with 10-20 sessions being effective for most individuals who benefit.
This was a relatively small study, so the work still requires replication. But, the authors have high hopes that this technology could eventually be used regularly to improve treatment response rates in mental health clinics. - http://www.elsevier.com/wps/find/authored_newsitem.cws_home/companynews05_01928

"From my research and that of others, I really think this may be the smoking gun," says Navy Capt. Mark Lyles, chair of medical sciences and biotechnology at the Center for Naval Warfare Studies at the Naval War College in Newport, R.I. "It fits everything — symptoms, timing, everything."
Lyles and other researchers found that dust particles — up to 1,000 of which can sit on the head of a pin — gathered in Iraq and Kuwait contain 37 metals, including aluminum, lead, manganese, strontium and tin. The metals have been linked to neurological disorders, cancer, respiratory ailments, depression and heart disease, according to the Environmental Protection Agency. Researchers believe the metals occur both naturally and as a byproduct of pollution.Researchers in and out of the military say the particles are smaller and easier to inhale than most dust particles, and that recent droughts in the region have killed desert shrubs that helped keep down that dust. The military's heavy vehicles have pounded the desert's protective crust into a layer of fine silt, Lyles says.

Too little salt can be harmful as well - (May 18, 2011 - The People’s Paharmacy - St. Louis Post-Dispatch) - It has been an article of faith for decades that everyone should reduce salt intake, but the data don't show that limiting sodium consumption makes a difference for otherwise healthy people.
The latest research in the Journal of the American Medical Association (May 4, 2011) reported that lower salt intake was not associated with lower blood pressure. The people who consumed the least salt had the greatest risk of death from cardiovascular complications.
As paradoxical as this seems, it is consistent with previous research. A national nutrition survey (Journal of General Internal Medicine, September 2008) found that low sodium intake was linked to higher cardiovascular mortality. A recent study of people with type 1 diabetes found that those with the lowest sodium intake were most likely to die during its 10-year duration (Diabetes Care, April 2011). - http://mcaf.ee/2brq8ac

Pelvic Widening Continues Throughout a Person's Lifetime - ScienceDaily (May 25, 2011) — By the age of 20, most people have reached skeletal maturity and do not grow any taller. Until recently it was assumed that skeletal enlargement elsewhere in the body also stopped by age 20.
But a new study by researchers at the University of North Carolina at Chapel Hill has found evidence that, even though you're not getting taller anymore, the pelvis ("hipbones") does continue to widen as people advance in age from 20 years to 79 years.
"I think it's a fairly common human experience that people find themselves to be wider at the age of 40 or 60 then they were at 20," said Laurence E. Dahners, MD, senior author of the study and a professor in the Department of Orthopaedics in the UNC School of Medicine. "Until recently we assumed that this was caused simply by an increase in body fat.
