A potential biomarker for pregnancy-associated heart disease?

2013-04-24
(Press-News.org) Peripartum cardiomyopathy (PPCM) is a deterioration in cardiac function that occurs in pregnant women during the last month or in the months following their pregnancy. This disorder can occur in women with no prior history of heart disease and the causes are not well understood. In this issue of the Journal of Clinical Investigation, Ingrid Struman and colleagues at the University of Liege in Liege, Belgium, identified a molecule, miR-146a, that can serve as a biomarker for peripartum cardiomyopathy. Struman and colleagues found that expression of miR-146a was induced by the nursing hormone prolactin. MiR-146a expression promoted vascular damage and was increased in a mouse model of PPCM. Conversely, loss of miR-146a in mice prevented PPCM. Importantly, miR-146a expression was elevated in the serum of pregnant women who developed PPCM, suggesting that serum miR-146a levels could predict which patients are at risk for the disease. In a companion commentary, Richard Kitsis of Albert Einstein College of Medicine in New York, discusses the potential implications of this work for the identification and treatment of PPCM.

No rebirth for insulin secreting pancreatic beta cells

2013-04-24
Pancreatic beta cells store and release insulin, the hormone responsible for stimulating cells to convert glucose to energy. The number of beta cells in the pancreas increases in response to greater demand for insulin or injury, but it is not clear if the new beta cells are the result of cell division or the differentiation of a precursor cell, a process known as neogenesis. Knowledge of how beta cells are created and maintained is critical to understanding diseases in which these cells are lost, such as diabetes. In this issue of the Journal of Clinical Investigation, ...

Firefly protein lights up degenerating muscles, aiding muscular-dystrophy research

2013-04-24
STANFORD, Calif. — Stanford University School of Medicine scientists have created a mouse model of muscular dystrophy in which degenerating muscle tissue gives off visible light. The observed luminescence occurs only in damaged muscle tissue and in direct proportion to cumulative damage sustained in that tissue, permitting precise monitoring of the disease's progress in the mice, the researchers say. While this technique cannot be used in humans, it paves the way to quicker, cheaper and more accurate assessment of the efficacy of therapeutic drugs. The new mouse strain ...

Odd experiments by 'America's first physiologist' shed light on digestion

2013-04-24
BOSTON—A fur trader who suffered an accidental gunshot wound in 1822 and the physician who saw this unfortunate incidence as an opportunity for research are key to much of our early knowledge about the workings of the digestive system, say speakers of an upcoming symposium. These speakers—Jay Dean, Ph.D., of the University of South Florida, Richard Rogers, Ph.D., of Pennington Biomedical Research Center, Louisiana State University, and Patrick Lambert, Ph.D., of Creighton University—will give their symposium presentation entitled, "William Beaumont: America's First Physiologist ...

Tinkerbella nana -- a new representative from the world of fairyflies

2013-04-24
Mymaridae, commonly known as fairyflies, are one of about 18 families of chalcid wasps. Fairyflies occur worldwide, except in Antarctica. They include the world's smallest known winged insect - Kikiki huna, the body length of which is only 155 μm, and the smallest known adult insect – the wingless male of Dicopomorpha echmepterygis which is only 130 μm. Although fairyflies are among the most common chalcid wasps, they are seldomly noticed by humans because of their minute size. Their apparent invisibility, gracile bodies and delicate wings with long fringes resembling ...

Costs to treat heart failure expected to more than double by 2030

2013-04-24
By 2030, you — and every U.S. taxpayer — could be paying $244 a year to care for heart failure patients, according to an American Heart Association policy statement. The statement, published online in the American Heart Association journal Circulation: Heart Failure, predicts: The number of people with heart failure could climb 46 percent from 5 million in 2012 to 8 million in 2030. Direct and indirect costs to treat heart failure could more than double from $31 billion in 2012 to $70 billion in 2030. "If we don't improve or reduce the incidence of heart failure ...

NASH diagnosis set to improve with non-invasive tool

2013-04-24
A Chinese study presented at the International Liver CongressTM 2013 has demonstrated the accuracy of a non-invasive test for non-alcoholic steatohepatitis (NASH) diagnosis. Non Alcoholic Fatty Liver disease (NAFLD) comprises two groups of patients; one group with simple steatosis which is relatively benign and one group with NASH which may progress to cirrhosis and hepatocellular carcinoma. Up to now the only means of distinguishing the two was to perform a liver biopsy. Phosphorus magnetic resonance spectroscopy (31P-MRS), which allows non-invasive in vivo assessment ...

Direct-acting antivirals now ready for prime time

2013-04-24
Amsterdam, The Netherlands, Wednesday 24 April 2013: New data from a number of clinical trials presented for the first time at the International Liver Congress™ 2013 demonstrate encouraging results in the use of new direct-acting antiviral agents (DAAs) for the treatment of hepatitis C. The following covers key results from the much anticipated Phase III trials conducted among HCV patients with a range of genotypes (GT 1 to 6) on DAA treatment. POSITRON A study of interferon (IFN)-ineligible, IFN-intolerant, or IFN-unwilling cirrhotic and non-cirrhotic GT 2 and ...

Battery and memory device in 1

2013-04-24
Resistive memory cells (ReRAM) are regarded as a promising solution for future generations of computer memories. They will dramatically reduce the energy consumption of modern IT systems while significantly increasing their performance. Unlike the building blocks of conventional hard disk drives and memories, these novel memory cells are not purely passive components but must be regarded as tiny batteries. This has been demonstrated by researchers of Jülich Aachen Research Alliance (JARA), whose findings have now been published in the prestigious journal Nature Communications. ...

New research findings on the brain's guardian cells

2013-04-24
Researcher Johan Jakobsson and his colleagues have now published their results in Nature Communications. "At present, researchers know very little about exactly how microglia work. At the same time, there is a lot of curiosity and high hopes among brain researchers that greater understanding of microglia could lead to entirely new drug development strategies for various brain diseases", says Johan Jakobsson, research group leader at the Division of Molecular Neurogenetics at Lund University. What the researchers have now succeeded in identifying is a deviation in the ...

Huddersfield scientist helps to reveal a link in the evolutionary chain

2013-04-24
An international team of scientists, including Dr Paul Brotherton from the University of Huddersfield, reveal that events after the initial migration of farmers into Europe had a major impact on the modern gene pool. The paper, published in Nature Communications, investigates a major component of the maternal population history of modern Europeans by focusing on haplogroup H mitochondrial genomes from ancient human remains. This genetic data is then compared with cultural changes taking place between the Early Neolithic (~5450 BC) and Bronze Age (~2200 BC) in Central Europe. ...
