The expression of the protein CLIP2 provides information on whether a papillary thyroid carcinoma was induced by radiation or had a sporadic origin. With this discovery, scientists have identified a new biomarker for the diagnosis of the cancer cause.
An obscure swatch of human DNA once thought to be nothing more than biological trash may actually offer a treasure trove of insight into complex genetic-related diseases such as cancer and diabetes, thanks to a novel sequencing technique developed by biologists.
Oysters were fit with biosensors in a new study to measure how they respond to changing environmental conditions or stressors on aquaculture farms. The results have implications for achieving and maintaining ideal conditions for targeted species in aquatic environments.
Two new studies show that despite public belief to the contrary, hands-free, voice-controlled automobile infotainment systems can distract drivers, although it is possible to design them to be safer. Apple's Siri and Chevrolet's MyLink were most distracting, while Toyota's Entune was least distracting, the study showed.
Children who start toilet training before age 2 have a three times higher risk of developing daytime wetting problems later, according to new research. Additionally, in the current study, early trainers were three times more likely to complain of constipation than normal trainers. "Almost all of the children who had wetting also had constipation," the authors noted.
Researchers have moved a step closer to making a simple blood test to detect early Alzheimer's disease available for screening older adults. The highly rigid guidelines will be used in research for blood-based biomarkers of Alzheimer's disease and will ensure every lab is following the same protocol when collecting blood, researchers said.
The 2014 Nobel Prize in Physics has been awarded to Isamu Akasaki, of Meijo University in Nagoya and Nagoya University, Japan; Hiroshi Amano, of Nagoya University, Japan; and Shuji Nakamura of the University of California, Santa Barbara, CA, USA "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources."
More than two million people are incarcerated in the United States, the world's highest incarceration rate. Researchers report that while many people need to be in prison for the safety of society, a majority are incarcerated due to behaviors linked to treatable diseases such as mental illness and addiction.
In a randomized clinical trial of antibiotic treatments for community-acquired pneumonia, researchers did not find that monotherapy with ²-lactam alone was worse than a combination therapy with a macrolide in patients hospitalized with moderately severe pneumonia.
Prenatal exposure to bisphenol A, a common chemical used in some plastics, appears to be inconsistently associated with diminished lung function and the development of persistent wheeze in children.
HIV drug regimens that do not include efavirenz are effective as first-line antiretroviral therapy, a new American clinical trial found. The finding is important for patients who are not eligible for treatment with efavirenz, including women considering becoming pregnant and patients with a history of severe psychiatric disorders.
Doctors appeared to 'wear down' during their morning and afternoon clinic sessions, and antibiotic prescribing rates increased the later the day got. "This corresponds to about 5 percent more patients receiving antibiotics at the end of a clinic session compared to the beginning," explained a reseracher. "Remedies for this problem might include different schedules, shorter sessions, more breaks or maybe even snacks."
Tiny vesicles containing protective substances that they transmit to nerve cells apparently play an important role in the functioning of neurons. As cell biologists have discovered, nerve cells can enlist the aid of mini-vesicles of neighboring glial cells to defend themselves against stress and other potentially detrimental factors. These vesicles, called exosomes, appear to stimulate the neurons on various levels: they influence electrical stimulus conduction, biochemical signal transfer, and gene regulation. Exosomes are thus multifunctional signal emitters that can have a significant effect in the brain.
Nearly a third of more than 2,100 patients with cancer interviewed at inpatient and outpatient care centers experienced a clinically meaningful level of mental or emotional distress that meets the strict diagnostic criteria for mental disorders including anxiety, depressive and adjustment disorders during the prior four weeks. The prevalence of these issues varied by cancer type.
Two studies published by health economists examine spending on oral anti-cancer drugs as well as a federal program designed to help the poor, which researchers say instead helps hospitals boost profits.
When it comes to distance running participation, even among contemporary U.S. distance runners, men are still much more likely than women to have a competitive orientation, according to researchers.
Targets to eliminate tuberculosis by 2050 are more likely to be met if new vaccines are developed for adults and adolescents instead of for infants, according to new research.
A new technique to identify populations of rare stem cells in bone marrow has been found by scientists. Until now, there has been no good way to separate MSCs from bone marrow cells that have already begun to differentiate into other cell types, but share the same molecules on the cell surface. This may be one reason why research results vary among labs, and why stem-cell treatments now in clinical trials are not as effective as they could be, says the paper's senior author.
The high heritability of exam grades reflects many genetically influenced traits such as personality, behavior problems, and self-efficacy and not just intelligence. The study looked at 13,306 twins at age 16 . The twins were assessed on a range of cognitive and non-cognitive measures, and the researchers had access to their GCSE (General Certificate of Secondary Education) scores.
A future where electricity comes mostly from low-carbon sources is not only feasible in terms of material demand, but will significantly reduce air pollution, a study says.
