Practical and predictive bioinformatics methods for the identification of potentially cross-reactive protein matches

A bioinformatics comparison of proteins introduced into food crops through genetic engineering provides a mechanism to identify those proteins that may present an increased risk of allergic reactions for individuals with existing allergies. The goal is to identify proteins that are known to be allergens or are so similar to an allergen that they may induce allergic cross-reactions. Three comparative approaches have traditionally been used, or considered for safety evaluations. One identifies any short (6-8) amino acid segment of the protein that exactly matches a known allergen sequence. The second is an overall primary sequence comparison using Basic Local Alignment Search Tool (BLAST) or FASTA to find matches of greater than 35% identity over 80 amino acids. The third is based on 3-D prediction programs to identify 3-D similarities that might predict potential cross-reactivity. The utility of each of these approaches was debated in the bioinformatics workshop. The consensus agreement from the expert workshop participants was that the short-segment match (e. g., 6-8 amino acids) provides an unacceptably high rate of false positive matches and an uncertain rate of true positive matches, and was not particularly useful for an allergenicity evaluation performed in the context of comprehensive safety evaluation. There was no consensus regarding the most appropriate bioinformatics method, an acceptable scoring criteria for triggering closer examination subsequent to a positive match, or an acceptable scoring mechanism for ranking the utility of the various 3-D approaches that were discussed during the workshop. However, the general consensus was that the most practical approach at this time is to evaluate primary sequence identities to known allergens using either FASTA or BLAST. While there was good agreement that identities of greater than 35% over 80 or more amino acids (recommended by Codex in 2003) is quite conservative, the conclusion was that additional data or studies would be needed to justify changing this criterion as there is some evidence that some individuals sensitized to proteins in evolutionarily conserved protein families may experience cross-reactions to proteins sharing approximately 40% identity.

Cichorium intybus L – cultivation,processing, utility,value addition and biotechnology,with an emphasis on current status and future prospects

Cultivation of chicory plants for various applications, such as utilisation of the root biomass for preparation of a coffee adjuvant, utilisation as a vegetable and, recently, utility of the plants for important phytochemicals, has received global attention. Chicory is widely grown in countries of different geographical locations owing to the economic importance of this crop. This review addresses cultivation, utility, phytochemical studies and pharmacological aspects, with an emphasis on biotechnological developments in recent years and safety evaluation of genetically modified chicory crops. These aspects are dealt with in detail to bring out the current status and future prospects of cultivation and utility of this economically important crop. © 2001 Society of Chemical Industry     

In vitro gastrointestinal bioavailability of arsenic in soils collected near CCA-treated utility poles

Because of the potentially high arsenic concentrations found in soils immediately adjacent to chromated copper arsenate (CCA)-treated wood structures and utility poles, CCA-contaminated soil ingestion may be a significant exposure route to arsenic for children. Therefore, a strong need exists to provide accurate data on oral relative bioavailability (RBA) of arsenic (in vivo or in vitro) in field-collected CCA-contaminated soils. The objectives of this study were (1) to assess arsenic bioaccessibility in contaminated soils collected near in-service CCA-treated utility poles, (2) to determine the influence of soil properties and arsenic fractionation on arsenic bioaccessibility, and (3) to estimate an average daily arsenic intake from incidental soil ingestion. Arsenic bioaccessibility (in vitro gastrointestinal (IVG) method) was determined on surface soil samples collected immediately adjacent to 12 CCA-treated utility poles after 18 months of service. Bioaccessible arsenic was also determined in 3 certified reference materials. Total arsenic concentrations in soils (<300 microm) varied from 37 +/- 2 to 251 +/- 12 mg/kg, irrespective of soil organic matter contentwith the major soil-bound arsenic species being As(V). Arsenic bioaccessibility ranged between 25.0 +/- 2.7 and 66.3 +/- 2.3% (mean value 40.7 +/- 14.9%). The mean value was in agreement with the in vivo arsenic RBA reported by Casteel et al. (2003) in soil near CCA-treated utility poles. Bioaccessible arsenic was positively correlated with total organic carbon content (r2 = 0.36, p < 0.05) and with water-soluble arsenic (2 = 0.51, p < 0.01), and was negatively correlated with clay content (r2 = 0.43, p < 0.05). Using conservative exposure parameters, the mean daily arsenic intake from incidental ingestion of contaminated soil near CCA-treated utility poles was 0.18 +/- 0.09 microg As kg(-1) d(-1). This arsenic intake appeared negligible compared to the daily intake of inorganic arsenic from water and food ingestion for children.     

COMPARISON OF GROUND VERSUS MECHANICALLY DESINEWED BEEF IN FRANKFURTERS

Six formulations of frankfurters were processed from three sources of lean (USDA choice minor cuts, USDA choice flanks and USDA utility triangles) that were comminuted by two systems (grinding and mechanical desinewing). Total frankfurter yields during smoking, chilling and reheating were not affected by formulation. Mechanical desinewing was effective in removing connective tissue from choice minor cut and utility triangle beef and reducing the incidence of gelling out in frankfurters made from choice minor cuts. Desinewing improved the ease in casing peelability only for frankfurters made from choice flanks. Sensory and physical characteristics were affected more by source of lean than by method of comminution. Frankfurters prepared from choice flanks had higher tenderness ratings, finer texture scores and lighter color than frankfurters made from choice minor cuts and utility triangles.
