Dynamic covalent and noncovalent assembly of -nitrosocumene in organic solvents and water.

-Nitrosocumene (-NC) exhibits dynamic N,N bonding, interchanging monomer and /-azodioxide dimer structures, the extent of which depends on the environment. As a solid, -NC is a Z-dimer; in organic solvent, the monomer is favored; and in water, dimers are favored. A supramolecular assembly of -NC is observed as a separate species by NMR in water, shown to be a novel nanometer-sized aggregate containing ∼2000 molecules.

Anti-amyloid treatment is broadly effective in neuronopathic mucopolysaccharidoses and synergizes with gene therapy in MPS-IIIA.

Mucopolysaccharidoses (MPSs) are childhood diseases caused by inherited deficiencies in glycosaminoglycan degradation. Most MPSs involve neurodegeneration, which to date is untreatable. Currently, most therapeutic strategies aim at correcting the primary genetic defect.

When it's neighbor's fault, a complicated ascending aortic aneurysm mimicking pulmonary embolism: A case report.

Thoracic aortic aneurysms represent a potentially life-threatening disease with increasing prevalence, probably related to the increasing mean age of the global population; the complications of thoracic aortic aneurysms can show multiple modes of presentation in the acute phase based on various factors, including the involvement of the structures with which the aneurysm is in close anatomical relationship. With this case report we want to show how it is possible that a complicated ascending aortic aneurysm can mimic an acute pulmonary embolism/acute cor pulmonale in the acute phase; the earliest possible differential diagnosis between pulmonary embolism and acute aortic disease is of crucial importance due to the opposite implications that the treatment of these two diseases have. < Aortic acute syndromes may mimic acute cor pulmonale; the principal aim is to raise the readers' awareness of this aspect as the earliest possible differential diagnosis between pulmonary embolism and acute aortic disease is of crucial importance due to the opposite implications that the treatment of these two diseases has.

Interaction of drought- and pathogen-induced mortality in Norway spruce and Scots pine.

Pathogenic diseases frequently occur in drought-stressed trees. However, their contribution to the process of drought-induced mortality is poorly understood. We combined drought and stem inoculation treatments to study the physiological processes leading to drought-induced mortality in Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) saplings infected with Heterobasidion annosum s.
