The effect of organic solvent on the structure and dynamics of proteins was investigated by multiple molecular dynamics simulations (1 ns each) of Candida rugosa lipase in water and in carbon tetrachloride. The choice of solvent had only a minor structural effect. For both solvents the open and the closed conformation of the lipase were near to their experimental X-ray structures (C(alpha) rms ...
In 2008-2009, types of organic solvents used and air-borne vapor concentrations were surveyed in 1909 laboratories in four large research institutions in accordance with current regulations. The results were classified into 5 groups in terms of research fields (agriculture, biology, medicine, natural science, and technology and engineering) and evaluated after the regulatory rules. Laboratory a...
Solvents represent an important group of environmental pollutants to which people are exposed daily in the workplace. The physico chemical properties of solvents may result in disturbances to cellular structures, including damage to DNA. However, the effects of mixtures of solvents are not well known. Mutations caused by environmental agents are related to cancer development and other degenerat...
A self-assembled M(2)L(4) palladium-pyridyl cluster with a "paddle-wheel" structure shows binding affinity in competitive organic solvents for neutral organic guests that possess both the correct size and electrostatic complementarity.
This paper concerns the sensitivity of artists’ oil paints to organic solvents. Specifically, it examines the respective capacities of single organic solvents and mixtures of solvents to cause swelling as a consequence of sorption into the paint and solvency action thereupon. The swelling power of a solvent is essentially an indicator of its relative strength in terms of action on the original ...
