| comparative assessment of methods for aligning multiple genome sequences. | multiple sequence alignment is a difficult computational problem. there have been compelling pleas for methods to assess whole-genome multiple sequence alignments and compare the alignments produced by different tools. we assess the four encode alignments, each of which aligns 28 vertebrates on 554 mbp of total input sequence. we measure the level of agreement among the alignments and compare their coverage and accuracy. we find a disturbing lack of agreement among the alignments not only in spe ... | 2010 | 20495551 |
| factors affecting infiltration and survival of salmonella on in-shell pecans and pecan nutmeats. | a study was done to determine the infiltration and survival characteristics of salmonella in pecans. the rate of infiltration of water into in-shell nuts varied among six varieties evaluated and was significantly (alpha = 0.05) affected by the extent of shell damage. the rate of infiltration at -20 or 4 degrees c was lower than the rate of infiltration into nuts at 21 or 37 degrees c when nuts were immersed in water at 21 degrees c. in-shell nuts immersed in a suspension of salmonella (8.66 or 2 ... | 2010 | 20615338 |
| dna identification confirms pecan weevil (coleoptera: curculionidae) infestation of carpathian walnut. | larvae found infesting fruit from a carpathian walnut, juglans regia l., tree in missouri were confirmed by dna analysis to be those of pecan weevil, curculio caryae (horn) (coleoptera: curculionidae). the infested walnut tree occurs in the midst of pecan weevil-infested pecans, carya illinoinensis (wang.) k. koch; the larval haplotypes were found to be identical to pecan weevil larvae from the region, indicating that the walnut infestation arose by association with infested pecan. this is the f ... | 2010 | 20857742 |
| differences in bacterial diversity of host-associated populations of phylloxera notabilis pergande (hemiptera: phylloxeridae) in pecan and water hickory. | host-associated differentiation (had) is the presence of genetically divergent, host-associated populations. it has been suggested that microbial symbionts of insect herbivores may play a role in had by allowing their insect hosts to use different plant species. the objective of this study was to document if host-associated populations of phylloxera notabilis pergande (hemiptera: phylloxeridae) in pecan and water hickory corresponded with differences in the composition of their associated bacter ... | 2011 | 21261774 |
| effects of combining microbial and chemical insecticides on mortality of the pecan weevil (coleoptera: curculionidae). | the pecan weevil, curculio caryae (horn), is a key pest of pecan [carya illinoinensis (wangenh.) k. koch]. current control recommendations are based on chemical insecticide applications. microbial control agents such as the entomopathogenic nematode, steinernema carpocapsae (weiser) and the fungus beauveria bassiana (balsamo) vuillemin occur naturally in southeastern u.s. pecan orchards and have shown promise as alternative control agents for c. caryjae. conceivably, the chemical and microbial a ... | 2011 | 21404833 |
| inactivation of salmonella on in-shell pecans during conditioning treatments preceding cracking and shelling. | studies were done to determine the effectiveness of conditioning treatments for killing salmonella in and on immersion-inoculated and surface-inoculated in-shell pecans. treatment of immersion-inoculated, dried, stored pecans in chlorinated water (400 μg/ml) reduced salmonella by not more than 1.6 log cfu/g. treatment of immersion-inoculated, dried, stored pecans in chlorinated water (200 μg/ml, 1 min) followed by soaking in water for 2 h at 21°c and treating for 10 min in water at 85 to 95°c re ... | 2011 | 21477473 |

| cloning and characterization of an 11s legumin, car i 4, a major allergen in pecan. | among tree nut allergens, pecan allergens remain to be identified and characterized. the objective was to demonstrate the ige-binding ability of pecan 11s legumin and characterize its sequential ige-binding epitopes. the 11s legumin gene was amplified from a pecan cdna library and expressed as a fusion protein in escherichia coli. the native 11s legumin in pecan extract was identified by mass spectrometry/mass spectrometry (ms/ms). sequential epitopes were determined by probing the overlapping p ... | 2011 | 21718052 |
| hepatoprotective effects of pecan nut shells on ethanol-induced liver damage. | the hepatoprotective activity of the aqueous extract of the shells of pecan nut was investigated against ethanol-induced liver damage. this by-product of the food industry is popularly used to treat toxicological diseases. we evaluated the phytochemical properties of pecan shell aqueous extract (ae) and its in vitro and ex vivo antioxidant activity. the ae was found to have a high content of total polyphenols (192.4±1.9mg gae/g), condensed tannins (58.4±2.2mg ce/g), and antioxidant capacity, and ... | 2011 | 21924598 |
| inactivation of salmonella on pecan nutmeats by hot air treatment and oil roasting. | studies were done to determine the effectiveness of hot air drying, dry roasting, and oil roasting in killing salmonella on pecan nutmeats. pecan halves and pieces were inoculated by immersion in a five-serotype suspension of salmonella or by surface application of powdered chalk containing the pathogen. hot air treatment of low-moisture (2.8 to 4.1%) and high-moisture (10.5 to 11.2%) immersion-inoculated nutmeats (initial population, 6.18 to 7.16 log cfu/g) at 120°c for 20 min reduced the numbe ... | 2011 | 21902912 |
| detection of allergy to nuts by the radioallergosorbent test. | the diagnosis of food allergy is often difficult to make by conventional means. histories are frequently ambiguous, and skin testing is of dubious reliability because of the number of false-positive and false-negative reactions. we have evaluated the radioallergosorbent test (rast) for the in vitro measurement of the specific ige antibodies to nuts, including brazil nut, almond, walnut, pecan, cashew, and the legume, peanut. serums were obtained from 18 patients with a history of nut allergy and ... | 2005 | 1262606 |
| comparative study of volatile oil content and antimicrobial activity of pecan cultivars growing in egypt. | the volatile oils obtained from the leaves of four pecan cultivars growing in egypt were evaluated for their chemical composition and antimicrobial activity. the selected cultivars (cv.) were carya illinoinensis (wangneh.) k. koch. cv. wichita, c. illinoinensis cv. western schley, c. illinoinensis cv. cherokee, and c. illinoinensis cv. sioux. the gas chromatography-mass spectrometry analyses revealed that the volatile oils from samples of the different cultivars differ in composition and percent ... | 2013 | 24180553 |
| an insect pupal cell with antimicrobial properties that suppress an entomopathogenic fungus. | soil-dwelling insects have developed various mechanisms to defend against pathogen infection. the pecan weevil, curculio caryae, spends two to three years in the soil inside an earthen cell. we hypothesized that the cell may possess antimicrobial properties. in a laboratory study, we tested the hypothesis using the fungus beauveria bassiana as a model. b. bassiana is a common endemic pathogen of c. caryae. we compared the number of colony-forming-units on selective media when b. bassiana was exp ... | 2015 | 25510575 |
| effects of entomopathogenic fungus species, and impact of fertilizers, on biological control of pecan weevil (coleoptera: curculionidae). | the pecan weevil, curculio caryae (horn), is a key pest of pecan, carya illinoinensis (wangenh.) k. koch. prior research indicated the potential for use of hypocreales fungi to suppress c. caryae. we compared the efficacy of two fungal spp., beauveria bassiana (gha strain) and metarhizium brunneum (f52), in their ability to cause c. caryae mortality. the fungus, b. bassiana, was applied to trunks of pecan trees (a method previously shown to be effective in c. caryae suppression) and efficacy was ... | 2013 | 23575015 |
| cumulative impact of a clover cover crop on the persistence and efficacy of beauveria bassiana in suppressing the pecan weevil (coleoptera: curculionidae). | the pecan weevil, curculio caryae (horn), is a key pest of pecan. endemic levels of the entomopathogenic fungus beauveria bassiana (balsamo) vuillemin can occur in pecan orchards and contribute to natural control of c. caryae. commercial formulations of the fungus can also be applied for suppression of c. caryae. we hypothesized that a clover cover crop enhances b. bassiana efficacy and persistence (e.g., by protecting the fungus against abiotic environmental stresses). the hypothesis was tested ... | 2012 | 22507002 |
