Body Louse Genome Sequenced

-
In a paper appearing in the early, online edition of the Proceedings of the National Academy of Sciences yesterday, an international research team reported that they have sequenced the genome of the human body louse, Pediculus humanus humanus.

In the process, the researchers also generated sequence that helped them piece together the genome of a bacterial symbiont residing in the louse. Together, the two genomes are providing clues about louse adaptations to obligate parasitism on the human body. In addition, those involved say the work may ultimately provide insights needed to pave the way for more targeted control measures.

"Understanding the genome should ultimately open up doors to better understanding how to deal with louse populations," co-senior author Barry Pittendrigh, an entomologist at the University of Illinois at Urbana-Champaign, told GenomeWeb Daily News.

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
