Only one-third of parents follow doctors' orders for kids all of the time

EUGENE, Ore. -- (March 18, 2013) -- University of Oregon chemists have synthesized organic molecular structures that move both positive and negative electrical charges -- a highly desired but often difficult combination to achieve in current efforts to create highly flexible electronic devices and other new-age technologies. The research utilized a family of readily available and inexpensive hydrocarbons known as indenofluorenes to build molecular scaffolding for integrative circuitry. An indenofluorene-derivative framework, said co-author Michael M. Haley, head of the ...

A new study from researchers at UH Rainbow Babies and Children's Hospital and other centers suggests that preterm infants with a low-grade bleeding in the brain may have similar neurodevelopmental outcomes as infants with no bleeding. The study appears online at JAMA Pediatrics. The study's lead author Allison Payne, MD MS, a neonatologist at UH Rainbow Babies and Children's Hospital and instructor at Case Western Reserve University School of Medicine, said, "The results are important because it is a large multi-center study showing different results than a recent study ...

WASHINGTON, DC – Heart disease is the leading cause of death for women in the United States. Yet historically, women have been less likely than men to receive evidence-based medical care for both the prevention and management of heart disease. In 1999 the American Heart Association (AHA) published the first clinical recommendations for the prevention of cardiovascular disease (CVD) in women. This was soon followed by the implementation of The Heart Truth® campaign for consumers in 2002 by the National Heart, Lung, and Blood Institute (NHLBI), which was expanded in 2004 ...

For years, scientists around the world have dreamed of building a complete, functional, artificial cell. Though this vision is still a distant blur on the horizon, many are making progress on various fronts. Prof. Roy Bar-Ziv and his research team in the Weizmann Institute's Material's and Interfaces Department recently took a significant step in this direction when they created a two-dimensional, cell-like system on a glass chip. This system, composed of some of the basic biological molecules found in cells – DNA, RNA, proteins – carried out one of the central functions ...

(Santa Barbara, Calif.) –– After almost four decades of absence from local waters, a special sea slug appears to be making a comeback, and marine scientists at UC Santa Barbara are eagerly anticipating its return. With its vivid blue and gold colors and its discovery by UC zoologists in 1901, the nudibranch Felimare californiensis, also known as the California chromodorid, has been a favorite species of sea slug for UC marine scientists and students for decades. But while it held a special place in their hearts, it lost its place in local waters, which once included La ...

One of the most basic laws of quantum mechanics is that a system can be in more than one state – it can exist in multiple realities – at once. This phenomenon, known as the superposition principle, exists only so long as the system is not observed or measured in any way. As soon as such a system is measured, its superposition collapses into a single state. Thus, we, who are constantly observing and measuring, experience the world around us as existing in a single reality. The principle of superposition was first demonstrated in 1922 by Otto Stern and Walther Gerlach, ...

The digital rectal exam is an important screening test that can discover prostate cancer that a prostate-specific antigen or PSA test may not, despite the higher sensitivity of the PSA test, according to Penn State College of Medicine researchers. The digital rectal examination is a procedure where a physician feels the surface of the prostate with a gloved finger. The doctor is able to feel any lumps or hard areas on the prostate. A PSA test checks for levels of prostate-specific antigen in the blood, with higher levels signaling potential cancer. As men age, the ...

Research led by a psychologist at the University of Liverpool has found that using memories of recent meals reduces the amount of food eaten later on. It also found that being distracted when eating leads to increased consumption. Researchers analysed 24 separate studies which had examined the impact of awareness, attention, memory and distraction on how much food we eat. They found that remembering meals, being more aware and paying added attention to meals results in lower food consumption and could help with weight loss programmes. Techniques such as writing down ...

Stroke, heart attacks and numerous other common disorders result in a massive destruction of cells and tissues called necrosis. It's a violent event: As each cell dies, its membrane ruptures, releasing substances that trigger inflammation, which in turn can cause more cellular necrosis. A new Weizmann Institute study may help develop targeted therapies for controlling the tissue destruction resulting from inflammation and necrosis. The study, conducted in the laboratory of Prof. David Wallach of the Biological Chemistry Department, focused on a group of signaling enzymes, ...

Milan, 18 March 2013 – A new study from Japan investigated various prognostic indicators, including clinico-pathological and pre-operative hematological factors to develop a novel prognostic factors-based risk stratification model for disease-specific survival (DSS) in bladder cancer (BCa) patients treated with radical cystectomy (RC). This large series demonstrated that two types of pre-operative haematological disorders assessed by haemoglobin (Hb) and C-reacted protein (CRP) are independent prognostic indicators for patients with BCa treated by RC. "Despite the wealth ...
