Postgenomic chemistry: New problems and challenges

Postgenomic chemistry : New problems and challenges *

New trends in chemistry induced by genetic engineering and genomic information are analyzed. Genomic information and bioinformatics make the identification of all molecular participants of biological processes possible. The methods of identification of enzymeactive sites from sequence data were demonstrated. The problems of “chemical proteomics” were formulated and analyzed. New biocatalytic pr...

Bioinorganic chemistry in the postgenomic era.

Genome sequencing has revolutionized all fields of life sciences. Bioinorganic chemistry is certainly not immune to this influence, which is presenting unprecedented challenges. A new goal for bioinorganic chemistry is the investigation of the linkages between inorganic elements and genomic information. This requires new advancements andor the development of new expertise in fields such as bioi...

New challenges in environmental chemistry

The major goal of this paper is to point out the frontiers of environmental chemistry and the new paradigms for the next decade, with especial focus to Latin America countries. To better address the issue, three different scenarios were selected: (a) major changes in laboratory routine and research activities; (b) extra-laboratory tendencies; and (c ) legal, political and social aspects. In the...

New Challenges and Old Problems

Infection control: old problems and new challenges.

Infection control faces radical changes at the beginning of the third millennium. The first part of this review focuses on problems not yet solved, such as 1) surveillance systems, which should be active and extremely flexible; 2) infection outbreaks in hospitals and strategies to avoid them; 3) hand washing and alternatives such as rapid hand antisepsis; 4) water and food in the hospital as po...
