The olfactory basis for attraction of the Bollworm helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) to host-plant flowers
… were found to elicit electroantennographic (EAG) responses from the antennae of female H. armigera. Compounds active in GC-EAG analyses of T. erecta floral headspace samples, identified by GC-MS and comparison of retention times on polar and non-polar GC columns with authentic standards, were …

Identification of substrate proteins of FtsH during sporulation of Bacillus subtilis
… The last part of this thesis was focused on the eag gene, which forms a bicistronic operon with Spo0E. Construction and analysis of an eag insertion mutant exhibited a slight increase in the sporulation frequency and in the amount of Spo0A. A transcriptional fusion between the promoter of the …

The role of chemicals in the location of host plants by midge pests of UK fruit crops
… was assessed using electroantennography (EAG) but there were not enough responses to conclude that any compound was EAG-active. Apple leaf midges lay their eggs on apple leaf shoots. A suite of chemicals was identified which are produced by apple shoots. EAG runs were carried out on female …

Determinantes moleculares de la modulación de la apertura y cierre del canal de K+ hERG por dominios citoplásmicos
El canal humano hERG pertenece a la familia eag (KCNH) de canales de potasio dependientes de voltaje. Debido a su peculiar comportamiento como "rectificador anómalo", hERG juega un papel crucial en la finalización del potencial de acción ventricular cardíaco, pero también un papel fundamental en la …

The chemical diversity of midge pheromones
… (GC) coupled to electroantennographic recording (EAG) showed two consistent responses from male midges and they were identified as 2,7-diacetoxyundecane and 7-acetoxyundecane-2-one respectively. The field testing with isomers of 2,7-diacetoxyundecane separated by HPLC revealed that the first and …

Control of perineurial glial growth in Drosophila melanogaster
… putative neurotransmitter/osmolyte transporter; eag, which encodes a potassium channel; and NF1, which encodes neurofibromin and is the Drosophila ortholog of the human gene responsible for Neurofibromatosis type1. I provide evidence that neurofibromin, in accordance with its role as a Ras …

Mating Success in Low-Density Gypsy Moth Populations
… Finally, a portable Electroantennogram (EAG) device was evaluated for its ability to detect disparlure sprayed for mating disruption in gypsy moth populations. The study found no relationship between the dose of artificial airborne pheromone and response of gypsy moth antenna as measured …

Response of Stomoxys calcitrans and Musca domestica (Diptera: Muscidae) to Volatile Organic Compound Profiles from Ontario, Canada Dairy Farms
… used Gas-Chromatography-Electroantennography (GC-EAG) to identify VOCs presenting electrophysiological activity in S. calcitrans, for further exploration of their significance in behavioural modification. The data collected illustrates that VOC profiles taken at livestock facilities are subject to …

Propiedades antioxidantes y funcionales de cinco algas chilenas sobre la calidad de pasta de salmón
… la mayor concentración de polifenoles (128 mg EAG/kg de alga seca) y que el extracto de Rhodymenia corallina presentó la mayor capacidad capturadora de radicales libres (IC50 = 0,22 mg EAG/ml). Se determinó el índice de peróxidos en pasta de salmón con adición de extractos de algas y el índice …

The quality of diabetes care in the community: practice, policy and culture
… with 15 members of the Expert Advisory Group (EAG) for Diabetes. Thematic analysis was applied to the data using 3 theories of the policy process as analytical tools. Results: The survey response rate was 44% (n=262). Results suggested care delivery was largely unstructured; 45% of GPs had a …

Feijão comum (Phaseolus vulgaris L.): ação do armazenamento sobre a composição química e nutricional e efeito in vivo da farinha integral e de seu hidrolisado proteico no estresse oxidativo e na inflamação
… totais foram menores na WF (140,0 ± 5,87 µg EAG/g) e maiores no PH (1.025,6 ± 99,14 µg EAG/g), sendo identificados dois fenólicos (catequina e kaempferol) na WF e apenas o kaempferol no PH. O consumo de PH reduziu (p<0,05) o ganho de peso, consumo alimentar, coeficiente de eficiência …

Avaliação da toxicidade e efeitos biológicos do látex extraído de Himatanthus drasticus (Mart.) PLUMEL
… dos compostos fenólicos (24,52 ± 0,21 µg EAG/mg). O teste de micronúcleo mostrou que o látex da janaguba não é mutagênico, mas pelo teste de cometa é considerado genotóxico. Esses resultados sugerem que o látex de H. drasticus possui segurança para uso agudo e potencial farmacológico …

Importance of floral scent compounds for the interaction between Silene latifolia (Caryophyllaceae) and the nursery pollinator Hadena bicruris (Lepidoptera: Noctuidae)
… These extracts were further used in GC-FID/EAG and GC-MS/EAG detections, respectively. Main compounds in the tested extracts often elicited main signals in the antennae (e.g. lilac aldehydes, phenyl acetaldehyde). Some compounds elicited main signals in the antennae, though they were only …

Roles of Small Rnas and Paralogous Proteins In Bacillus Anthracis Virulence Gene Regulation
… PagR1. PagR1 also regulates <em>sap</em> and <em>eag</em>, two genes encoding components of the surface layer (S-layer), a protein layer found between the cell wall and capsule which serves as a mounting structure for key surface-associated proteins. Genomic and transcriptomic studies identified a …
