Alfalfa is an important perennial forage crop in Idaho supporting dairy and cattle industries that is typically grown in the same field for as many as 4 years. Alfalfa stands of different ages were subjected to screening for viruses using high-throughput sequencing and RT-PCR. The two most common viruses found were alfalfa mosaic virus and bean leafroll virus, along with Medicago sativa amalgavirus, two alphapartitiviruses, and one deltapartitivirus. Additionally, a new flavi-like virus with an unusual genome organization was discovered, dubbed Snake River alfalfa virus (SRAV). The 11,745 nt, positive-sense (+) RNA genome of SRAV encodes a single 3835 aa polyprotein with only two identifiable conserved domains, an RNA-dependent RNA polymerase (RdRP) and a predicted serine protease. Notably, unlike all +RNA virus genomes in the similar size range, the SRAV polyprotein contained no predicted helicase domain. In the RdRP phylogeny, SRAV was placed inside the flavi-like lineage as a sister clade to a branch consisting of hepaci-, and pegiviruses. To the best of our knowledge, SRAV is the first flavi-like virus identified in a plant host. Although commonly detected in alfalfa crops in southern Idaho, SRAV sequences were also amplified from thrips feeding in alfalfa stands in the area, suggesting a possible role of Frankliniella occidentalis in virus transmission. 相似文献

N-nitroso-N-methyloctadecylamine in hair-care products 总被引:1,自引:0,他引:1
Fifty-three cosmetic products containing one or more of the ingredients N,N-dimethyloctadecylamine oxide, N,N-dimethyloctadecylamine and N-benzyl-N,N-dimethyloctadecylammonium chloride were analysed for N-nitroso-N-methyloctadecylamine by gas chromatography with detection by a Thermal Energy Analyzer. [1-14C]N-Nitroso-N-methyloctadecylamine was used as an internal standard. Eight of 11 products containing N,N-dimethyloctadecylamine oxide and three of 38 products containing N-benzyl-N,N-dimethyloctadecylammonium chloride were found to contain N-nitroso-N-methyloctadecylamine at levels ranging from 28 to 969 ppb. In photolysis experiments, all of these products exhibited a loss of Thermal Energy Analyzer response for N-nitroso-N-methyloctadecylamine following irradiation by ultraviolet light. In two cases, the presence of N-nitroso-N-methyloctadecylamine was confirmed by combined gas chromatography-mass spectrometry. 相似文献

Our goal was to determine whether time-dependent changes in respiratory motor output in vitro could be minimized by altering bath solution composition. Adult turtle brainstems were bathed in standard solution, nutrient-rich Dulbecco's Eagle media (100 or 25% concentration), or standard solution with phenylbiguanide (PBG, 5-HT3 agonist which increases respiratory drive). Except for a 63% frequency increase in PBG solution, hypoglossal bursts were unaltered within 100 min of observation. Respiratory activity was abolished within 7 h in 100% Dulbecco's compared with a mean of 24-31 h in other test solutions. At 12 h, burst frequency decreased faster in standard solution and 25% Dulbecco's (-0.28+/-0.07 and -0.13+/-0.05 bursts/h, respectively) compared with PBG solution (-0.09+/-0.04 bursts/h); amplitude declined at approximately 2%/h in all solutions. The tendency for episodic discharge decreased gradually in standard solution, but was eliminated in 25% Dulbecco's and PBG solution. Certain bath solutions may minimize time-dependent frequency reductions but may also cause breathing pattern changes. 相似文献

Background: The assessment of health related quality of life (HRQOL) has increasingly been recognized as an important adjunct to medical outcome parameters in the monitoring of cystic fibrosis (CF) patients and in clinical studies. The Cystic Fibrosis Questionnaire (CFQ) is a disease-specific HRQOL instrument for CF patients developed in France. Translations are currently being validated in four different countries. The aim of the present study was to validate the German adaptation of the CFQ-14+. Method: On the basis of results from a first dataset (n = 197 CF adolescent and adult patients), revisions were made and retested in a second sample of 103 patients. Results: The final revised version showed good construct validity. The same nine HRQOL domains as in the French original CFQ-14+ emerged from the analyses as structurally robust scales. The internal consistencies of the HRQOL scales ranged from 0.71 to 0.94. The instrument's clinical validity was supported by severely ill patients reporting lower HRQOL than less severely ill patients on most scales. Conclusion: We conclude that the evidence supports the validity and reliability of the instrument. An important future area of application is the use in comparative multi-center international studies. 相似文献

Relating Body Image to Psychological and Sexual Functioning in Child Sexual Abuse Survivors 总被引:1,自引:0,他引:1
Cognitive-affective body image variables and their relation to long-term psychological and sexual functioning were investigated in a community sample of 57 female adult child sexual abuse (CSA) survivors and 47 comparison subjects. The Body-Self Relations Questionnaire and the Body Esteem Scale were administered to assess cognitive-affective body image. Group comparisons indicated that, after controlling for actual weight status, survivors evaluated their health more negatively and reported less body esteem regarding their sexual attractiveness than comparison subjects. Body image variables related to health and sexual attractiveness significantly explained variance on symptom measures that reflect the diverse CSA long-term sequelae. Results suggest the need for careful assessment of body image disturbances and the development of effective interventions targeting body image in the treatment of CSA survivors. 相似文献
