Participated in a Structure-Based Drug Design workshop/course at the Institute Pasteur de Montevideo (Montevideo, Uruguay, Nov. 3-8). This was an intensive drug discovery workshop in collaboration with Profs. P. Michels (University of Edinburg) and W. Hol (University of Washington, Seattle). The course was focused on novel methods and techniques for drug discovery with emphasis on Neglected Diseases. You can find more about the course and the Institute Pasteur de Montevideo here. There were lectures during an entire week , posters, and also practical sessions reviewing several computational techniques, among them 'docking techniques'. There was also a full practical session devoted to the use of the AtlasCBS webserver.

Presented two talks at 23rd International Congress of Crystallography in Montreal, Canada (IUCr2014), Aug. 5-12. The first one was related to the presentation of Crystallography in a dramatic context. I reviewed the work that I have been doing on my own (Play: Picasso Meets Crystallography) and later in collaboration with Jill Campbell and Greg Gerhard (play: Bernal's Picasso) to present the concepts and history of Crystallography in a dramatic content. Further details can be found in the 'Bernal's Picasso' tab of this website. More details can also be found on the blog: www.crystaledges.org.
The second was related to the presence of symmetry in Art forms and
particularly in Rosewindows in Gothic Cathedrals. This presentation focused on the paper recently published in Acta Cryst vol. D70, published this past March. This is a theme that was mentioned before in this 'news and views' . The abstract of this presentation can also be presented in the www.crystaledges.org.
I will be happy to share more information if you are particularly interested.
Best wishes and enjoy the rest the summer.
There will be an upcoming paper in Future of Medicinal Chemistry (FMC), relating to the incorporation of the AtlasCBS and Ligand Efficiency framework into the StarDrop™ software (www.Optibrium.com). There have been quite a few publications in the field, particularly relating to the value of 'Ligand Efficiency Metrics' to guide drug discovery. Some of the papers are reviewed in the upcoming paper in FMC and perspectives for the future are presented.

There is a pair of papers coming out in Acta Cryst D. One
about the structure of PurC from S. pneumoniae with my colleagues at UIC: N. Wolf,
M. Johnson and
Prof. L. Fung. A second, more intriguing, will be an essay on the series
'Notes of a
Protein Crystallographer' about the symmetry of the Rose Windows in
Cathedrals and the meaning of symmetry.
I'll provide details and links as soon as they come out.
I'll be in Cambridge, UK, Jan. 25-Feb. 4 working with my
colleagues at Optibrium on the implementation of the AtlasCBS software in
their StarDrop(TM) software
package. I should be back in Chicago, Feb. 8 and at the UIC campus soon
I will be in Paris, Jan. 20-24 for the events related to the
commemoration of the International Year of Crystallography (IYCr2014),
the IUCr and UNESCO. This is to celebrate the 100th year anniversary of the
unveiling of the very first crystallographic structure (NaCl) using X-rays
by the Bragg's (W.H. and W.L Bragg) in Cambridge, UK in 1913. Consult the
'crystaledges.org' for more details.
Leaving the UIC campus for a month stay in Europe.
Landing in Paris, Jan. 11, I'll be in Saarbrucken, Germany,
giving a Workshop on Protein Crystallography and Structure-Based
Drug Design in the laboratory of Prof. Rolf Hartmann, University of
Saarlandes, Department of Drug Optimization.
Happy New Year and best wishes to you and your family,
friends and colleagues for 2014 and beyond. See the last posting on the blog
for a reflective poem entitled 'Season's Lament' about Christmas trees.
Returned to UIC after first successful workshop about
the concepts and usage of the AtlasCBS concepts and tool
at the Helmholtz Institute of Pharmaceutical Research in Saarbruecken,
Germany (Sept. 30-Oct. 1).
The workshop was run in collaboration with the colleagues of Optibrium,
Ltd (UK) that now offers the AtlasCBS application as an add-on to their
software Stardrop(TM). Link
After the workshop, attended meeting in Getxo, Bilbao
(Spain) in honor of Jorge Navaza (Grenoble, France), recognizing his
contributions to the implementation of the Fast Rotation Function and
other mathematical and computational tools in crystallography and electron
microscopy. (See blog: Crystal Edges).
Currently at UIC. Blog 'Crystal Edges' inaugurated to
commemorate the International Year of Crystallography in 2014 (IYCr2014).
