The first study of its kind in the world — involving 336 children aged between six months and 16 years old — has shown that installing a water softener for three months brings no additional relief for eczema sufferers. Up to one fifth of all children of school age have eczema, along with about one in 12 of the adult population. Anecdotal reports from patients have suggested that hard water may worsen atopic eczema. Population surveys have also suggested a possible link between atopic eczema prevalence and the degree of water hardness. It had been hoped that water softeners ...

Philadelphia, PA, 16 February 2011 - Lithium, introduced in the late 1940's, was the first "wonder drug" in psychiatry. It was the first medication treatment for the manic and depressive episodes of bipolar disorder and it remains among one of the most effective treatments for this disorder. In the past 15 years, as molecular mechanisms underlying the treatment of bipolar disorder began to emerge, basic research studies conducted in animals began to identify neuroprotective and perhaps neurotrophic effects of this important medication. The identification of these ...

Pioneering Spanish provinces in terms of early prevention of breast cancer, such as Navarre and the Basque Country, record lower death rates, although the trend is towards the figures levelling out all over Spain. These are the results of a study carried out by Spanish researchers, which analyses the number of women who died between 1975 and 2005. "The Canary Islands, Balearic Islands, some parts of Catalonia, Valencia and Murcia, as well as the south west region, have higher breast cancer death rates, although there is a trend towards the geographical differences disappearing", ...

The president's budget includes $31.829 billion for the National Institutes of Health ($745 million increase over 2010); $7.8 billion for the National Science Foundation ($1.2 billion increase over 2010); and $2.747 billion for the Food and Drug Administration ($382 million increase over 2010). The budget proposes $5.8 billion for ...

Tomatoes spend so much time on shelves and in refrigerators that an estimated 20 percent are lost to spoilage, according to the U.S. Department of Agriculture (USDA). But scientists with USDA's Agricultural Research Service (ARS) are working with colleagues at Purdue University to extend the shelf life of tomatoes. The research also may lead to tomatoes that taste better and are more nutritious. ARS is USDA's principal intramural scientific research agency, and the research results support the USDA priority of promoting international food security. Autar Mattoo, a ...

What matters for commuters is not just if the train will be on time, but how long the journey will take. It's an important factor in public transportation and can make the difference in helping commuters choose mass transit over more polluting and costly transport like cars or airplanes. Dr. Tal Raviv and his graduate student Mor Kaspi of Tel Aviv University's Department of Industrial Engineering in the Iby and Aladar Fleischman Faculty of Engineering have developed a tool that makes passenger train journeys shorter, especially when transfers are involved — a computer-based ...

Smokers who continue to smoke while undergoing radiation treatments for head and neck cancer fare significantly worse than those who quit smoking before therapy, according to a study in the February issue of the International Journal of Radiation Oncology•Biology•Physics, an official journal of the American Society for Radiation Oncology (ASTRO). Although the association between tobacco smoking and head and neck cancers has long been established, there had been little data until now showing whether continued smoking during treatment affects prognosis. "I've always ...

TACOMA, WA —February 16, 2011— An article published in a forthcoming issue of the Journal of Traumatic Stress is one of the first to provide evidence of the effectiveness of exposure therapy with active duty military service members suffering from posttraumatic stress disorder (PTSD). The study shows that virtual reality exposure therapy resulted in significant reductions in PTSD symptoms after an average of seven treatment sessions. Additionally, 62 % of patients reported clinically meaningful, reliable change in PTSD symptoms. During the treatment the soldier repeatedly ...

A psychological scientist in Germany has found a way that cell phones, and specifically texting, have hacked into our brains. Just by typing the numbers that correspond to the letters in a word like "love," we can activate the meaning of that word in our minds. The results are published in Psychological Science, a journal of the Association for Psychological Science. For the study, Sascha Topolinski and his students at the University of Würzburg in Germany created a list of German words that can be typed on a cell phone keypad without typing the same digit twice in a ...

EAST PROVIDENCE, R.I. – Latino siblings of children developmental disabilities such as Down syndrome and autism may face their own challenges, including anxiety and lower school performance, according to a new study led by researchers with the Bradley Hasbro Children's Research Center. "When a child has a disability, all members of the family are affected, including siblings," said lead author Debra Lobato, Ph.D., of the Bradley Hasbro Children's Research Center. "However, little attention has been paid to the influence of cultural factors on the functioning of siblings. ...

Ottawa – Patients who participate in clinical trials expect that their personal information will remain confidential, but a recent study led by Dr. Khaled El-Emam, Canada Research Chair in Electronic Health Information at the CHEO Research Institute, found that the security practices used to transfer and share sensitive files were inadequate. The two-part study, entitled "How Strong Are Passwords Used to Protect Personal Health Information in Clinical Trials?", published today in the Journal of Medical Internet Research, showed that the majority of passwords used to ...

RIVERSIDE, Calif. – Geologists drilling an exploratory geothermal well in 2009 in the Krafla volcano in Iceland encountered a problem they were simply unprepared for: magma (molten rock or lava underground) which flowed unexpectedly into the well at 2.1 kilometers (6,900 ft) depth, forcing the researchers to terminate the drilling. "To the best of our knowledge, only one previous instance of magma flowing into a geothermal well while drilling has been documented," said Wilfred Elders, a professor emeritus of geology in the Department of Earth Sciences at the University ...

Researchers from Mount Sinai School of Medicine have discovered a novel function of brain insulin, indicating that impaired brain insulin action may be the cause of the unrestrained lipolysis that initiates and worsens type 2 diabetes in humans. The research is published this month in the journal Cell Metabolism. Led by Christoph Buettner, MD, Assistant Professor of Medicine in the Division of Endocrinology, Diabetes and Bone Disease at Mount Sinai School of Medicine, the research team first infused a tiny amount of insulin into the brains of rats and then assessed glucose ...

COLUMBUS, Ohio – Children as young as 5 years old can learn how to use a computer mouse, new research suggests. While age is an important component in determining how well a child controls a mouse, the study also found that how frequently a child practices may be even more important. "Learning how to use a computer has become as important as writing and reading in the classroom," says Alison Lane, an assistant professor of occupational therapy at Ohio State University. "Since the frequency of computer mouse use is as important as age, it might be beneficial to introduce ...

Frogs appear to be very sensitive to progestogens, a kind of pharmaceutical that is released into the environment. Female tadpoles that swim in water containing a specific progestogen, levonorgestrel, are subject to abnormal ovarian and oviduct development, resulting in adult sterility. This is shown by a new study conducted at Uppsala University and published today in the scientific journal Aquatic Toxicology. Many of the medicines that people consume are released into the environment via sewage systems. Progestogens are hormone preparations used in contraceptives, cancer ...

TORONTO, February 16, 2011 − One of the tough challenges a parent faces when a child dies is to learn how to parent the surviving children, and the task begins immediately, according to York University psychology professor Stephen Fleming. From the moment their child dies, parents are faced with the two extremes of loss and life – the suffocating loss of a child and the ongoing, daily demands from their surviving children, says Fleming, co-author of the recently-published book, Parenting After the Death of a Child: A Practitioner's Guide. "The challenge that parents ...

Proposed cuts to the National Institutes of Health (NIH) budget for 2011 will limit the nation's ability to advance patient care and public health. The American Society of Nephrology (ASN) strongly opposes the proposed $1.6 billion reduction to the NIH budget included in the continuing resolution (fiscal year 2011) being debated in the House of Representatives. The nation's longstanding commitment to better health has established the United States as a world leader in medical research and innovation. This leading position will be endangered should the 5.2 percent decrease ...

Scientists are reporting for the first time that previously unrecognized substances released by algae blooms have the potential to act as endocrine disruptors, which can interfere with the normal activity of reproductive hormones. The effect is not caused by microcystin toxins, long recognized as potentially harmful to humans and aquatic animals, but as yet unidentified substances. As a result, the scientists are calling for a revision of environmental monitoring programs to watch for these new substances. The findings appear in ACS's journal Environmental Science & Technology. Theodore ...

A long, urgent search for proteins in the blood of pregnant women that could be used in early diagnosis of ectopic pregnancy (EP) has resulted in discovery of biomarkers that seem to be specific enough to begin testing in clinical trials, scientists are reporting in a new study in ACS's Journal of Proteome Research. David Speicher and colleagues explain that ectopic pregnancy happens when an embryo does not attach normally inside the mother's uterus, but instead attaches and begins growing elsewhere. Most occur inside one of the Fallopian tubes, which link the ovaries ...

Scientists in Hungary are reporting that the potential health effects of last October's Red Mud Disaster, one of the worst environmental accidents in Europe, may be less dangerous than previously feared. Their study, reported in ACS's journal Environmental Science & Technology, concludes that the dust from the mud may be no more harmful than particles of ordinary urban air pollution. Mihály Pósfai and colleagues point out that a burst dam at a factory that processes aluminum ore last October inundated areas near Ajka in northern Hungary with more than 700,000 cubic yards ...

A Massachusetts General Hospital (MGH) study has identified a new role for an important enzyme in preparing lung tissue for the development of metastases. Published in the early edition of Proceedings of the National Academy of Sciences, the report describes how focal adhesion kinase (FAK) is involved in producing areas of vascular leakiness in lung tissue – known to be part of the premetastatic process – and increases expression of a molecule that attracts cancer cells to potential metastatic sites. "Blood from all tissues of the body travels to the lungs for oxygenation, ...

CHAMPAIGN, Ill. – A new study from the University of Illinois concludes that very high biomass prices would be needed in order to meet the ambitious goal of replacing 30 percent of petroleum consumption in the U.S. with biofuels by 2030. A team of researchers led by Madhu Khanna, a professor of agricultural and consumer economics at Illinois, shows that between 600 and 900 million metric tons of biomass could be produced in 2030 at a price of $140 per metric ton (in 2007 dollars) while still meeting demand for food with current assumptions about yields, production costs ...

Poised at the starting gate are palm oil, sugar cane, corn cobs, and switch grass. On your mark, get set... This is not a race among fruits and vegetables, but instead a real-life contest to decide which biofuel raw materials and technologies make it to the gas pump. That quest to develop a sustainable supply of affordable biofuels and bring them to the market is the topic of the cover story in the current edition of Chemical & Engineering News (C&EN), ACS's weekly newsmagazine. C&EN Senior Correspondent Stephen Ritter notes that scientists have largely met the technical ...

TORONTO, Ont., February 16, 2011 — One in five homeless people with tuberculosis die within a year of their diagnosis, according to a study led by St. Michael's Hospital's Dr. Kamran Khan. And that number remains unchanged over the last decade despite recommendations calling for greater improvements in prevention and control of tuberculosis in homeless shelters. A provincial coroner's inquest into the death of Joseph Teigesser, a homeless man who died of tuberculosis in Toronto in 2001, made 13 formal recommendations. These included provincial funding for a centralized ...

On 7 February 2011, the German Institute for Quality and Efficiency in Health Care (IQWiG) published the results of a search update for evidence-based clinical practice guidelines on coronary heart disease (CHD). The aim of the report is to identify those recommendations from current guidelines of high methodological quality that may be relevant for the planned revision of the corresponding disease management programme (DMP). According to the results of the report, there is no compelling need for revision of any part of the DMP. However, IQWiG identified various aspects ...
