Platinum compounds cisplatin, carboplatin and oxaliplatin are commonly used to treat cancer. But these drugs can only treat a limited number of tumours and some types of cancer are now showing resistance. The drugs are also highly toxic and cause unwanted side effects. Drugs that target the site of disease without harming healthy tissue are better and have been explored by using the sex hormone oestrogen attached to a Pt compound. These target oestrogen receptors which are over-expressed in most breast cancer tumours.

I am delighted to announce details of the 2nd Dalton Transactions International Symposium to be held in Shanghai and Hong Kong in November 2010. This 2010 Symposium follows the very successful Symposium held in China in October 2009. 9 world class presentations (6 at each venue) will be given.
The 2nd Dalton Transactions International Symposium will take place in two venues. 16th November will see the Symposium hosted in Shanghai, as part of the 11th Conference on Solid State Chemistry and Inorganic Synthesis. The Symposium will then move to Hong Kong on 18th November.
Speaker details of both days of the Symposium are:
16th November 2010, in Shanghai:
18th November 2010, in Hong Kong:

An IUPAC task group has recently published their recommendations for the definition for the hydrogen bond.
“The hydrogen bond is an attractive interaction between a hydrogen atom from a molecule or a molecular fragment X–H in which X is more electronegative than H, and an atom or a group of atoms in the same or a different molecule, in which there is evidence of bond formation.”
The recommendations continue with a list of experimental and theoretical criteria that can be used as evidence for the presence of the hydrogen bond, and finish with characteristics that are typical of hydrogen bonded systems.
For more information on the task group and to view the provisional recommendation see the IUPAC report.
