The study shows that maternal demoralization, a measure of psychological distress that can affect a mother's ability to cope with stressful situations, was linked with several behavioral problems, including anxiety, depression, and attention problems. Effects of demoralization were greatest among children with higher levels of prenatal exposure to polycyclic aromatic hydrocarbons in air pollution.

This striking body plan has evolved many times independently in the more than 500 million years of vertebrate animals history. Based on the current state of knowledge, the extreme elongation of the body axis occurred in one of two ways: either through the elongation of the individual vertebrae of the vertebral column, which thus became longer, or through the development of additional vertebrae and associated muscle segments.  Mon, 07 Oct 2013 09:40:40 EDT http://www.sciencedaily.com/releases/2013/10/131007094002.htm http://www.sciencedaily.com/releases/2013/10/131006204207.htm A unique study of 16 pairs of identical twins in which one twin is obese and the other lean has yielded some surprising results. In 8 of the pairs of twins, the obese twin was as 'metabolically healthy' as his or her lean co-twin, while in the other 8 pairs, the obese twin had a poorer blood fat profile, higher liver fat and increased insulin production and resistance, and higher blood pressure -- all hallmarks of unhealthy obesity.

The method is so efficient that, for the first time, a thousand genes can be studied in parallel in ten thousand single human cells. Applications lie in fields of basic research and medical diagnostics. The new method shows that the activity of genes, and the spatial organization of the resulting transcript molecules, strongly vary between single cells.

Now, researchers have mapped this EUV emission and developed a theoretical model that explains how the emission depends on the three-dimensional shape of the plasma. In doing so, they found a previously untapped source of EUV light.

Deprived of oxygen and other essential nutrients, cell death continues possibly leading to progressive loss of heart function and congestive heart failure. Rsearchers found that dying heart cells still contain enough oxygen for metabolism, and additional short-term spikes of oxygen keep the cells alive and active.

Incidence doubles in a population for every five years over the age of 65 years, so that almost one fifth of those living to 85 can expect to have the condition and a third of those over the age of 95 will likely be affected. As the population ages through better nutrition and healthcare, we can expect absolute numbers of people with dementia to continue to rise.

Our respiratory system consists of a bronchial tree designed to transport air through the lungs combined with an alveolar system designed to capture the oxygen. Both are subjected to different type of optimizations. Only tree-like structures, the paper shows, are able to efficiently feed organs above a small size, below which organs are solely fed by diffusion.

According to the authors, not only does it make life much better for children and families, it also saves society money.

A team of researchers has identified a pathway that seems to be important in driving the chronic infection and that could now potentially be targeted for therapy.

Researchers know which mutations underlie some cohesinopathies, but have developed little understanding of the downstream signals that are disrupted in these conditions.

This suppression leads to kidney cell damage. In obese people the same with kidney disease, suppressed autophagy.

The team discovered a novel virulence mechanism of Botrytis cinerea, a pathogen that can infect more than 200 plant species, causing serious gray mold disease on almost all fruits and vegetables that have been around, even at times in the refrigerator, for more than a week.

Imaging with PET/CT has shown that dense white blood cells in the outermost connective tissue in the vascular wall, increased C-reactive protein and a loss of smooth muscle cells in the middle layer of the vascular wall are all factors that may indicate future AAA rupture.
