Oestrogen and mental state

Article Abstract:

Several researchers conducted studies on the relationship of estrogen and mental state in female rats. The results showed that sudden increases in estrogen levels stimulates a similar increase in the density of 5-hydroxytryptamine2A (5-HT2A). Previous studies have shown that mood and mental state is partly affected by changes in 5-HT2A levels. The results suggest that estrogen levels play a crucial role in controlling mood and mental state.

An intermolecular (H2O)10 cluster in a solid-state supramolecular complex

Article Abstract:

Complex supramolecular frameworks are formed spontaneously by 'programmed' molecular subunits during chemical self-assembly. Biological self-assembly is normally dynamic and is dependent on the participation of non-covalent interactions. Water plays an important role in such processes. A new study uses the icelike solvent water cluster (H2O)10 to prepare a crystal structure of a three-dimensional, self-assembled supramolecular complex.

Microsecond-resolved XAFS of the triplet excited state of Pt2(P2O5H2)4-/4

Article Abstract:

A new method for characterizing the excited-state structures of inorganic compounds has been devised that unites X-ray absorption fine-structure (XAFS) with rapid-flow laser spectroscopy. Time-resolved XAFS was tested by applying it to tetrakis(pyrophosphito)diplatinate(II), or Pt2(P2O5H2)4-/4, with results that indicated the reliability of the new technique. Enhanced XAFS should have many uses in chemistry and biology.
