HealthSouth Issues Preliminary Comments on the President's Healthcare Budget Proposal and Announces Plans to Host a Conference Call

...are services, HealthSouth looks forward to offering insights on the current fragmented and inefficient post-acute care system that, in many instances, constrains providers from offering comprehensive post-acute care and services to all patients who would benefit from such care. HealthSouth will...

Study looks at mitochondrial variation in sperm traits and sperm competitive ability

... refine the efforts to understand mitochondrial effects on male fertility. The fundamental insight that strict maternal inheritance of mitochondria constrains the ability of males to respond adaptively to selection has led to major advances in the study of human male infertility, said Jeanne Zeh, the princip...

The memories you want to forget are the hardest ones to lose

...sant and unpleasant emotional memories were resistant to intentional forgetting. The UNC findings contribute to understanding the ways that emotion constrains mental control and to the question of whether intentional forgetting can be helpful in coping with painful or traumatic experiences. Our findings a...

iQ200 Automated Urine Microscopy Analyzer

Features:...acks by mixing, sampling, and analyzing automatically. Urine particles in the sample are imaged in a planar flowcell that hydrodynamically orients and constrains particles within the focal plane of a microscope objective. The resolution is sufficient to distinguish between RBCs and WBCs and the field of view is...

Complexity constrains evolution of human brain genes

Despite the explosive growth in size and complexity of the human brain, the pace of evolutionary change among the thousands of genes expressed in brain tissue has actually slowed since the split, millions of years ago, between human and chimpanzee, an international research team reports in the Dece...

Breaking the ties that bind: New hope for biomass fuels

... can shift to remain stable under a wide range of temperatures. This plasticity allows the material to swap different types of hydrogen bonds but also constrains the molecules so that they must form bonds in the weaker configuration described by Langan and his colleagues. Most important, Shen and Gnanakaran's m...

... coast of Greenland. However, how deep water circulates within these basins is not well known. Noting that the shape of the ocean bottom significantly constrains fluid motion in weakly stratified deep waters, Siland et al. study the positions of neutrally buoyant subsurface drifting floats that were deployed ac...

Genes and nutrition influence caste in unusual species of harvester ant

... on Pogonomyrmex harvester ants have found colonies in which becoming a worker or gyne is determined exclusively by genetic differences. Such rigidity constrains the colony's ability to adaptively adjust to environmental realities. For example, colonies that have few workers and yet produce a lot of larvae that...

Scientists may have solved an ecological riddle

...m developed two new hypotheses for understanding the distribution of nitrogen fixing plants across global ecosystems. The first is that temperature constrains the distribution of nitrogen fixation, contributing to the lack of nitrogen-fixing trees in mature forests at high latitudes. The second that nitr...

At the root of nutrient limitation, ecosystems are not as different as they seem

...a system responds positively to the initial nitrogen addition, it is said to be nitrogen-limited, because the availability of nitrogen instantaneously constrains the productivity of the ecosystem. The converse is true in phosphorus-limited systems. Plant production in both cases is limited by the nutrient i...

New insights into how lasers cut flesh

As a result, the explosions tend to be considerably smaller than they are in water. This reduces the damage that t...
