the central nervous system, were found to be an anaesthetic target of many general anaesthetics. On the other hand, ketamine is a well-known N-methyl-D-aspartate (NMDA) receptor antagonist (Franks2006;2008). However, some general anaesthetics may affect proteins indirectly through the plasma memb...
Biology cannot only improve upon fossil-derived molecules — there is the opportunity to make better ones. 21 N.S. Kruyer, M.J. Realff, W. Sun, C.L. Genzale, P. Peralta-Yahya Designing the bioproduction of Martian rocket propellant via a biotechnology-enabled in situ resource utilization...
The layer of ozone molecules in the stratosphere is one of the Earth's defences against harmful solar radiation, particularly the shorter wavelengths such as UV-B (280–315 nm) and UV-C (100–280 nm) light. Since the 1970s, catalytic breakdown of ozone mol- ecules has occurred ...
In the presence of a concomitant viral infection, which acts as a second signal, an immune stimulatory environment is made by the release of pro-inflammatory cytokines and co-stimulatory molecules. In the second way drugs directly interact with immune receptors, but those bindings are labile and ...

Provided that more than 50% of human DNA is transcribed, and that this transcription may be driven in both directions, we may expect that more than a quarter of the above complementary motifs are transcribed within the RNA molecules in the antisense orientation relatively to adenoviral gene ...
How many moles of water are there in 1.000 l at stp? Assume the density of water is 1000 kg/m3? Stoichiometry: Stoichiometry is the branch of chemistry which deals with the measurement of chemical substances in a chemical reaction. This measurement is important...
