The problem breaks down into two parts: defining the clusters (., a list of members for each family) and building multiple alignments of the members. Previous approaches to construct comprehensive fam- ily databases have either concentrated on aligning short conserved regions, 6–8 often starting from the manually constructed clusters in Prosite, 9 or full domain alignments using either clusters that were derived manually from PIR2 or automatically. 10 An issue here is whether to aim for conserved regions only or whole domain alignments. By using short conserved motifs either in the form of a pattern or an alignment can indicate when a protein contains a known domain. Motif matches are often useful to indicate functional sites. However,. | Pesticide-Induced Diseases Database health Wide Range of Diseases Linked to Pesticides Database supports policy shift from risk to alternatives assessment By Kagan Owens Jay Feldman and John Kepner The common diseases affecting the public s health are all too well-known in the 21st century asthma autism and learning disabilities birth defects and reproductive dysfunction diabetes Parkinson s and Alzheimer s diseases and several types of cancer. Their connection to pesticide exposure continues to strengthen despite efforts to restrict individual chemical exposure or mitigate chemical risks using risk assessment-based policy. The Pesticide-Induced Diseases Database launched by Beyond Pesticides facilitates access to epidemiologic and laboratory studies based on real world exposure scenarios that link public health effects to pesticides. The scientific literature documents elevated rates of chronic diseases among people exposed to pesticides with increasing numbers of studies associated with both specific illnesses and a range of illnesses. With some of these diseases at very high and perhaps epidemic proportions there is an urgent need for public policy at all levels -local state and national to end dependency on toxic pesticides replacing them with carefully defined green strategies. Data Supports Policy Change The database is a tool to support efforts to eliminate the continued use of hazardous pesticides in favor of green strategies that emphasize non-toxic and least-toxic alternative practices and products. The studies in the database show that our current approach to restricting pesticide use through risk assessment-based mitigation measures is not working. This failed human experiment must be ended. The warnings of those who have expressed concerns about risk assessment such as EPA Administrator under Presidents Nixon and Reagan William Ruckelshaus have been borne out by three decades of use and study. Mr. Ruckelshaus in 1984 said We .
