Researchers Develop Tool To Study Genes

-
Two Texas A&M University researchers have developed a computational tool that will help scientists more accurately study complex units of clustered genes, called operons, in bacteria. The tool, which allows scientists to analyze many bacterial genomes at once, is more accurate than previous methods because it starts from experimentally validated data instead of from statistical predictions, they say. The researchers hope their tool will lead to a better understanding of the complex genetic mechanisms involved in a cell’s functioning. “Eventually, we want to try to improve our tool to make it better and more accurate,” Sze said. “Although our tool can analyze a lot of bacteria at the same time, it compares each bacterium to E. coli separately. So the ultimate goal would be to develop a tool that will analyze them all together.”

Sequence Analysis is still sexy:Dual Descriptor Method for Biological Sequence Analysis

-
The emergence of “Systems Biology” in recent years highlights the systematic viewpoint of bio-system modeling. Building on such a background, Dual Descriptor Method, a generic methodology for biological sequence analysis is proposed. From a systematic perspective, Dual Descriptor is defined as a two element set of Composition Weight Map and Position Weight Function which aim at reflecting the composition and permutation information of a sequence. An alternate training algorithm is provided to get an optimum description of the building patterns of the sequences. In this paper , dual descriptor method has been applied to the analysis of two typical problems of molecular biology: gene identification and the prediction of protein function. Satisfactory and insightful results are achieved. Owing to the generality of this methodology, dual descriptor method has wide application perspective for many problems of pattern recognition, especially those involved in “Systems Biology”.

Abbott Laboratories Buys Piramal Healthcare Limited Biz for $3.72B

-
Abbott May 21 announced a definitive agreement with Piramal Healthcare Limited to acquire full ownership of Piramal's Healthcare Solutions business (Domestic Formulations), a leader in the Indian branded generics market, for an up-front payment of $2.12 billion , plus $400 million annually for the next four years, giving Abbott the No. 1 position in the Indian pharmaceutical market. This further accelerates Abbott's emerging markets growth following the recent acquisition of Solvay Pharmaceuticals and announcements last week of Abbott's collaboration with Zydus Cadila as well as the creation of a new stand-alone Established Products Division to focus on expanding the global markets for its leading branded generics portfolio. "This strategic action will advance Abbott into the leading market position in India , one of the world's most attractive and rapidly growing markets," said Miles D. White , chairman and chief executive officer, Abbott. &quo
