Recently, the use of the Bayesian network as an alternative to existing tools for similarity-based virtual screening has received noticeable attention from researchers in the chemoinformatics field. The main aim of the Bayesian network model is to improve the retrieval effectiveness of similarity-based virtual screening. To this end, different models of the Bayesian network have been developed. In our previous works, the retrieval performance of the Bayesian network was observed to improve significantly when multiple reference structures or fragment weightings were used. In this article, the authors enhance the Bayesian inference network (BIN) using the relevance feedback information. In this approach, a few high-ranking structures of unknown activity were filtered from the outputs of BIN, based on a single active reference structure, to form a set of active reference structures. This set of active reference structures was used in two distinct techniques for carrying out such BIN searching: reweighting the fragments in the reference structures and group fusion techniques. Simulated virtual screening experiments with three MDL Drug Data Report data sets showed that the proposed techniques provide simple ways of enhancing the cost-effectiveness of ligand-based virtual screening searches, especially for higher diversity data sets. © 2011 Society for Laboratory Automation and Screening.

The present study is the first investigation of digenetic trematode parasites in C. bajad, a commercially important teleost fish species of the Red Sea, Coast of Yemen from AL-Khatheib region, in the coast city of Hodeidah, during the period from January to December 2006. A total of 112 C. bajad (Local name, Bayad) were examined, 16 specimens were found harboring Lecithochirium sp. (Lecithochirium, Hemiuridae). The prevalence and mean intensity of infection were 14.3 % and 2.9 respectively. And the number of parasite per fish range 1-6. Prevalence and intensity of infection was positively correlated with host size (increasing with host size increasing). Host sex does not seem to affect prevalence of infection. The present work represents the first record for the presence of this parasite in C. bajad fish in Yemen's coastal Red Sea water. Source

A total of 85 fish specimens of the great barracuda, Sphyraena barracuda (Edwards, 1771) from the Red Sea, Yemeni coastal waters were examined for infection with the polyopisthocotylean monogeneans during the period from October 2009 till May 2010. The results showed the occurrence of two species of these parasites; Vallisiopsis contorta Subhapradha, 1951 and Pentatres sphyraenae Euzet and Razarihelisoa, 1959. The occurrence of these monogeneans represents their first record from the Yemeni fishes of the Red Sea. Source

The monogenean parasite Chauhanellus indicus Rastogi, Kumar and Singh, 2004 is described here for the first time from the gills of the sea catfish Tachysurus dussumieri (Valenciennes) from the Red Sea coast of Yemen. The ecological indexes of infection during the period from March 2009 and June 2010 were calculated as prevalence of 40% and intensity of 1-12 (3.17). The relation of the infection with both fish length and sex, and preference of site of infection were discussed. Source

Many of the conventional similarity methods assume that molecular fragments that do not relate to biological activity carry the same weight as the important ones. One possible approach to this problem is to use the Bayesian inference network (BIN), which models molecules and reference structures as probabilistic inference networks. The relationships between molecules and reference structures in the Bayesian network are encoded using a set of conditional probability distributions, which can be estimated by the fragment weighting function, a function of the frequencies of the fragments in the molecule or the reference structure as well as throughout the collection. The weighting function combines one or more fragment weighting schemes. In this paper, we have investigated five different weighting functions and present a new fragment weighting scheme. Later on, these functions were modified to combine the new weighting scheme. Simulated virtual screening experiments with the MDL Drug Data Report23 and maximum unbiased validation data sets show that the use of new weighting scheme can provide significantly more effective screening when compared with the use of current weighting schemes. © 2011 American Chemical Society.
