We have developed a new computational framework for merging odor response data sets from heterogeneous studies, creating a consensus metadatabase, the database of odor responses (DoOR). As a result, we obtained a functional atlas of all available odor responses in Drosophila melanogaster. Both the program and the data set are freely accessible and downloadable on the Internet (http://neuro.uni-konstanz.de/DoOR). The procedure can be adapted to other species, thus creating a family of "olfactomes" in the near future. Drosophila melanogaster was chosen because of all species this one is closest to having the complete olfactome characterized, with the highest number of deorphanized receptors available. The database guarantees long-term stability (by offering time-stamped, downloadable versions), up-to-date accuracy (by including new data sets as soon as they are published), and portability (for other species). We hope that this comprehensive repository of odor response profiles will be useful to the olfactory community and to computational neuroscientists alike.

Fire is a key natural disturbance influencing physical, chemical, and biological processes in the Cerrado. Ash, a fire byproduct, may significantly influence soil macrofauna through its chemical properties. Dung beetles (Scarabaeinae), critical components of Cerrado soil macrofauna, provide key ecological functions and services.

The role of residential dampness and molds in the occurrence of respiratory tract infections is not well understood. We assessed the relations between cumulative lifetime and time-specific dampness and mold exposures and the occurrence of upper and lower respiratory tract infections (URTI and LRTI) from pregnancy to 27 years of age in the prospective population-based Espoo Cohort Study (n=2,567). We assessed three questionnaire-based reports of residential exposure to water damage, moisture on the surfaces, visible mold and mold odor, and incidence rates of URTI and LRTI when children were 1-6, 7-13, and 21-27 years.

Feeding on the nutrients from fruits and flowers is vital for mosquitoes and increases their lifespan, reproduction, and flight activity. Olfaction is a key sensory modality in mediating mosquito responses to nutrient sources. Previous studies have demonstrated that fruits and flowers can vary in attractiveness to mosquitoes, with some sources preferred over others.

Plant viruses are known to indirectly manipulate insect vector behavior by altering host-plant phenotypes, yet the mechanisms by which they directly regulate vector behavior to enhance transmission remain poorly understood. Here, we reveal how the southern rice black-streaked dwarf virus (SRBSDV) reprograms the host preference of its planthopper vector, Sogatella furcifera, from infected to healthy rice plants by disrupting immune-olfactory crosstalk. We demonstrate that the SRBSDV-encoded P8 protein competitively binds to the S.

The current work aimed to investigate the effects of fermentation of , , and on the physicochemical, electronic sensory evaluation, and flavour characteristics of heat-sterilized tomato juice (HTJ). The results indicated that LAB fermentation significantly decreased the pH, sucrose, and glucose, and lactic acid was increased. E-nose and tongue analyses revealed that the response to organic sulfides, terpenoids, and sourness increased after LAB fermentation HS-SPME-GC-MS and OAV revealed that heat-sterilization resulted a significant loss of aroma compounds (38.
