Abstract:
AbstractMost plant species depend upon insect pollination services, including many cash and subsistence crops. Plants compete to attract those insects using visual cues and floral odor which pollinators associate with a reward. The cacao tree, Theobroma cacao, has a highly specialized floral morphology permitting pollination primarily by Ceratopogonid midges. However, these insects do not depend upon cacao flowers for their life cycle, and can use other sugar sources. To understand how floral cues mediate pollination in cacao we developed a method for rearing Ceratopogonidae through several complete lifecycles to provide material for bioassays. We carried out collection and analysis of cacao floral volatiles, and identified a bouquet made up exclusively of saturated and unsaturated, straight-chain hydrocarbons, which is unusual among floral odors. The most abundant components were tridecane, pentadecane, (Z)-7-pentadecene and (Z)-8-heptadecene with a heptadecadiene and heptadecatriene as minor components. We presented adult midges, Forcipomyia sp. (subgen. Forcipomyia), Culicoides paraensis and Dasyhelea borgmeieri, with natural and synthetic cacao flower odors in choice assays. Midges showed weak attraction to the complete natural floral odor in the assay, with no significant evidence of interspecific differences. This suggests that cacao floral volatiles play a role in pollinator behavior. Midges were not attracted to a synthetic blend of the above four major components of cacao flower odor, indicating that a more complete blend is required for attraction. Our findings indicate that cacao pollination is likely facilitated by the volatile blend released by flowers, and that the system involves a generalized odor response common to different species of Ceratopogonidae.

Abstract:
Aroma is one of the most important quality indicators of tea. However, this evaluation method is a subjective one. In this study, the volatiles of tea with 5 types were determined by headspace solid-phase micro-extraction (HS-SPME) combined with gas chromatography mass spectrometry (GC-MS). The aroma intensity and odor characteristics of teas were comparatively analyzed based on the OAV-splitting method. The results showed that OAV were green tea (492.02), red tea (471.88), oolong tea (302.74), white tea (68.10), and dark tea (55.98). The odor index I(o) indicated that green tea was strong-flavor tea with highlight green accompanied by fruity, woody and fatty odors; oolong tea was strong-flavor tea with fruity and fatty accompanied by woody, floral and green odors; red tea was strong-flavor tea with highlight fruity accompanied by woody, green and floral odors; white tea was a light-flavor tea with floral, woody and green odors; and dark tea was light-flavor tea with woody and floral notes accompanied by fatty and green odors. These results fitted perfectly with the people’s consensus on these teas, and proved that the OAV-splitting method is feasible to evaluate the aroma intensity and odor characteristics of tea aroma. We suggest that the digital evaluation of tea aroma can facilitate people’s communication.

Abstract Whereas contextual influences in the visual and auditory domains have been largely documented, little is known about how chemical senses might be affected by our multisensory environment. In the present study, we aimed to better understand how a visual context can affect the perception of a rather pleasant (floral) and a rather unpleasant (damp) odor. To this end, 19 healthy participants performed a series of tasks including odor detection followed by perceptual evaluations of odor intensity, pleasantness, flowery, and damp characters of both odors presented at 2 different concentrations. A visual context (either congruent or incongruent with the odor; or a neutral control context) preceded odor stimulations. Olfactomotor responses as well as response times were recorded during the detection task. Results showed an influence of the visual context on semantic and motor responses to the target odors. First, congruency between context and odor increased the saliency of the olfactory feature of the memory trace, for the pleasant floral odor only (higher perceived flowery note). Clinical applications of this finding for olfactory remediation in dysosmic patients are proposed. Second, the unpleasant odor remained unaffected by visual primes, whatever the condition. In addition, incongruency between context and odor (regardless of odor type) had a disruptive effect on odor sampling behavior, which was interpreted as a protective behavior in response to expectancy violation. Altogether, this second series of effects may serve an adaptive function, especially the avoidance of, or simply vigilance toward, aversive and unpredictable stimuli.

Abstract:
Molecules with pleasant odors, unacceptable odors, and even serious toxicity are closely related to human social life. It is impractical to identify the odors of molecules in large quantities (particularly hazardous odors) using experimental methods. Computer-aided methods have currently attracted increasing attention for the prediction of molecular odors. Here, through models based on multilayer perceptron (MLP) and physicochemical descriptors (MLP-Des), MLP and molecular fingerprint, and convolutional neural network (CNN), we conduct the two-class prediction of odor/no odor, fruity/no odor, floral/no odor, and woody/no odor, and the multi-class prediction of fruity/flowery/woody/no odor on our newly refined molecular odor datasets. We show that three kinds of predictors can robustly predict molecular odors. The MLP-Des model not only exhibits the best prediction results (the AUC values are 0.99 and 0.86 for the two- and multi-classification models, respectively) but can also well reflect the characteristics of the structure–odor relationship of molecules. The CNN model takes 2D molecular images as input and can automatically extract the structural features related to molecular odors. The proposed models are of great help for the prediction of molecular odorants, understanding the underlying relationship between chemical structure and odor perception, and the discovery of new odorous and/or hazardous molecules.

Abstract:
Lavender and its products have excellent flavor properties. However, most studies focus on the aroma profiles of lavender essential oil (LEO). The volatiles in lavender extracts (LEs), either in volatile compositions or their odor characteristics, have rarely been reported. In this study, the odor characteristics of LEs and LEO were comprehensively investigated by gas chromatography-mass spectrometry (GC-MS), coupled with sensory evaluation and principal chemical analysis (PCA). In addition, the extraction conditions of lavender extracts from inflorescences of Lavandula angustifolia Mill. were optimized. Under the optimal conditions of extraction, twice with 95% edible ethanol as the solvent, the LEs tended to contain the higher intensity of characteristic floral, herbal and clove-like odors as well as higher scores of overall assessment and higher amounts of linalool, linalool oxides I and II, linalyl acetate, lavandulyl acetate and total volatiles than LEO. PCA analysis showed that there were significant differences on the odor characteristics between LEO and LEs. The LEO, which was produced by steam distillation with a yield of 2.21%, had the lower intensity of floral, clove-like, medicine-like, pine-like and hay notes, a lower score of overall assessment and lower levels of linalool oxides I and II, linalyl acetate, lavandulyl acetate and total volatiles compared with LEs, whereas the relative contents of linalool and camphor in LEO were significantly higher than that in LEs. Furthermore, the earthy, green and watery odors were only found in LEO. Concerning the odor characteristics and volatile compositions, the LEs had better odor properties than LEO. These results provided a theoretical basis for the industrial preparation of lavender-related products.

Abstract:
The six algal metabolites, at concentrations of 20-225 μg/l, were oxidized with potassium permanganate, chlorine, or chlorine dioxide at doses of 0.25-3 mg/l. Flavor profile analysis (FPA) was used to determine the odors of the solutions before and after oxidation. Linoleic and palmitic acids, which are odorless compounds, were oxidized to odorous products by all three oxidants. The odor intensity of β-cyclocitral (grape, sweet tobacco) and phenethyl alcohol (rose, floral) was only slightly decreased by any of the oxidants. Oxidation by permanganate or chlorine either eliminated or greatly reduced the odors associated with linolenic acid (watermelon) and 2t,6c-nonadienal (cucumber); chlorine dioxide was ineffective at reducing the cucumber odor of 2t,6c-nonadienal. Oxidation, at doses typically applied for drinking water treatment, can result in the destruction of certain algae-related odors but in the formation of other odors.

Abstract:
Abstract Congruent visual cues augment sensitivity to brief olfactory presentations and habituation of odor perception is modulated by central-cognitive processing including context. However, it is not known whether habituation to odors could interact with cross-modal congruent stimuli. The present research investigated the effect of visual congruence on odor detection sensitivity during continuous odor exposures. We utilized a multimethod approach, including subjective behavioral responses and reaction times (RTs; study 1) and electroencephalography (EEG, study 2). Study 1: 25 participants received 2-min presentations of moderate-intensity floral odor delivered via olfactometer with congruent (flower) and incongruent (object) image presentations. Participants indicated odor perception after each image. Detection sensitivity and RTs were analyzed in epochs covering the period of habituation. Study 2: 25 new participants underwent EEG recordings during 145-s blocks of odor presentations with congruent or incongruent images. Participants passively observed images and intermittently rated the perceived intensity of odor. Event-related potential analysis was utilized to evaluate brain processing related to odor–visual pairs across the period of habituation. Odor detection sensitivity and RTs were improved by congruent visual cues. Results highlighted a diminishing influence of visual congruence on odor detection sensitivity as habituation occurred. Event-related potential analysis revealed an effect of congruency on electrophysiological processing in the N400 component. This was only evident in early periods of odor exposure when perception was strong. For the first time, this demonstrates the modulation of central processing of odor–visual pairs by habituation. Frontal negativity (N400) responses encode the aspects of cross-modal congruence for odor–vision cross-modal tasks.

Abstract:
Abstract Natural odors are mixtures of volatile chemicals (odorants). Odors are encoded as responses of distinct subsets of the hundreds of odorant receptors and trace amine-associated receptors expressed monogenically by olfactory sensory neurons. This is an elegantly simple mechanism for differentially encoding odors but it is susceptible to complex dose–response relationships and interactions between odorants at receptors, which may help explain olfactory phenomena, such as mixture suppression, synthetic versus elemental odor processing, and poorly predictable perceptual outcomes of new odor mixtures. In this study, in vivo tests in freely behaving mice confirm evidence of a characteristic receptor response pattern consisting of a few receptors with strong responses and a greater number of weakly responding receptors. Odorant receptors responsive to an odor are often unrelated and widely divergent in sequence, even when the odor consists of a single species of odorant. Odorant receptor response patterns to a citrus odor broaden with concentration. Some highly sensitive receptors respond only to a low concentration but others respond in proportion to concentration, a feature that may be critical for concentration-invariant perception. Other tests find evidence of interactions between odorants in vivo. All of the odorant receptor responses to a moderate concentration of the fecal malodor indole are suppressed by a high concentration of the floral odorant, α-ionone. Such suppressive effects are consistent with prior evidence that odorant interactions at individual odorant receptors are common.

O licuri (Syagrus coronata) é uma palmeira que floresce e frutifica durante o ano inteiro, tendo grande importância ecológica e econômica, uma vez que fornece hábitat e alimento para diversos seres vivos, inclusive para a subsistência de populações humanas. Em populações nativas encontradas no Parque Nacional do Catimbau, a fenologia da espécie foi monitorada em quatro áreas (total de 120 indivíduos). Também foram identificados os visitantes florais, a composição química dos odores florais e a variação de temperatura das flores durante a antese, levando em consideração as fases reprodutivas (feminina e masculina), o sexo das estruturas reprodutivas (flores pistiladas e estaminadas) e o período do dia (manhã e noite). O fitness reprodutivo foi comparativamente analisado para polinização diurna vs noturna, entomófila vs anemófila. Amostras de odores florais foram coletadas através de “headspace” dinâmico a partir de flores pistiladas e estaminadas, bem como nas suas respectivas brácteas. O estudo da fenologia evidenciou duas áreas sazonais, enquanto duas outras produziram eventos contínuos de reprodução. A riqueza e abundância de visitantes florais foram maiores nas inflorescências masculinas que nas femininas. O fitness reprodutivo não mostrou diferença entre os tratamentos de polinização. Por sua vez, análises de odor floral demonstraram diferenças de compostos isolados nas brácteas e inflorescências, mas não entre as fases reprodutivas; a quantidade de odor emitido diferiu nas brácteas nas fases femininas e masculinas, mas não nas inflorescências, as quais apresentaram quantidades similares de compostos. Não foi evidenciado fenômeno de termogênese floral, nem ao longo do dia, nem entre as fases reprodutivas. Estratégias como o fornecimento de recursos em abundância e hábitat para visitantes florais, liberação diferenciada de odor e floração contínua, podem estar associadas à garantia do fluxo gênico dentro e entre populações dessa espécie de Syagrus.
Licuri (Syagrus coronata) is a palm tree that blooms and bears fruit throughout the year, having an ecological and economic importance, as it provides habitat and food for many living beings, including for the livelihoods of human populations. In native populations, found in Catimbau National Park, the phenology of species was monitored in four areas (total 120 individuals). Also flower visitors were identified, the chemical composition of floral scents and temperature variation of flowers at anthesis, taking into account the reproductive stages (male and female), sex of the reproductive structures (pistillate and staminate flowers) and the period the day (morning and evening). The reproductive fitness was comparatively analyzed for day vs. night pollinated and entomophilous vs anemophilus. Samples of floral odours were collected through "headspace" dynamic from pistillate and staminate flowers as well as in their respective bracts. The study of phenology showed two seasonal areas, while two others produced continuous reproductive events. The richness and abundance of floral visitors were higher in male than in female inflorescences. The reproductive fitness showed no difference between pollination treatments. In turn, floral odor analysis showed differences in isolated compounds in the bracts and flowers, but do not between the reproductive stage; the amount of odor emitted differed in the bracts in male and female phases, but not in inflorescences, which showed similar amounts of compounds. Floral thermogenesis phenomenon was not evidenced neither throughout the day nor between reproductive stages. Strategies such as providing abundant resources and habitat for floral visitors, differentiated release of odor and continuous flowering, may be associated with the guarantee of gene flow within and among populations of this species of Syagrus.

Cette thèse aborde l’écologie et l’évolution des relations qu’entretiennent les orchidées du genre Ophrys avec leurs pollinisateurs. L’approche comparative et la combinaison (i)

d’analyses chimiques de phéromones sexuelles et de parfums floraux, (ii) d’analyses génétiques avec des outils moléculaires, et (ii) de tests de comportement réalisés sur les insectes in situ nous ont permis d’éclairer certains aspects méconnus de ces interactions inter-spécifiques. La pollinisation des orchidées du genre Ophrys est assurée par des mâles d'abeilles ou de guêpes solitaires qui opèrent une tentative d’accouplement (pseudocopulation) sur le labelle des fleurs. L'attraction des pollinisateurs est généralement hautement spécifique, régie par un mimétisme des signaux (chimiques, visuels, tactiles) des femelles des espèces d'insectes concernés. Malgré cette spécificité, des hybrides se forment occasionnellement en conditions naturelles, témoignant de la perméabilité partielle des barrières d'isolement reproductif entre espèces. Au cours de

Abstract:
This chapter examines how flowers use olfactory signals to attract pollinators. Floral scents mostly result from the production of small amounts of simple volatile organic compounds. The molecular size of these components largely determines their volatility, and hence the distance they will travel from the plant over a given time span. Plant volatiles emitted as scents are typically lipophilic compounds, all of which are able to cross biological membranes and evaporate into the atmosphere readily. The chapter frst describes different types of floral scents before discussing the techniques used in the collection and measurement scents. It then considers variation in floral scents, along with the discrimination and detection ranges of floral odors. It also explains the importance of odor learning to visitors’ ability to discriminate and to maintaining reproductive isolation for the plant. Finally, it provides an overview of interactions of scents with other floral signals used for advertisement.

Abstract:
As pirazinas pertencem a uma classe de compostos voláteis que constituem o aroma de diversos alimentos e bebidas, contribuindo com notas de odor diversas, como pungência, doce, avelã, floral, torrado, caramelo, nozes, semelhantes ao café, cacau e amêndoas. Elas podem ser produzidas naturalmente nos alimentos, formadas a partir do tratamento térmico ou por meio de microrganismos, aumentando sua concentração em matrizes alimentícias de acordo com o grau de torrefação. Portanto, essa revisão tem como objetivo discutir dados já reportados na literatura sobre as características sensoriais desses compostos que compõem o aroma dos alimentos submetidos ao processo de torra ou cocção, assim como também a descrição dos principais métodos de análise dessas substâncias.

Abstract:
The effects of prefermentative cold skin-contact technique using Malvasia aromatica were studied as a first step to adapt to the climate change related effects in order to intensify the aroma potential of white wines of the D.O. “Vinos de Madrid” keeping the organoleptic characteristics of the region. Major volatile compounds were extracted by liquid–liquid extraction and quantified by GC-FID. Minor volatile compounds were determined by HS-SPME/GC–MS. Sensory analysis were also carried out to describe and quantify attributes of the wines. A total of 37 components were identified and quantified. Volatile components showed mixed behavior depending on the skin-contact time. Skin-contact for longer helps to enhance the floral character provided by some compounds contained in the skin, especially linalool and 2-phenyl etanol and were impact odorants of Malvasia aromatica wine based on odor activity values (OAVs).

Abstract:
Anaerobic bacteria will not grow when incubated with 10% CO2 in room air, but they vary in their tolerance of different levels of oxygen. Anaerobic bacteria are important commensal flora of the skin and oral, intestinal, and pelvic mucosae, and are classified according to their Gram-staining characteristics and ability to produce spores: (1) Gram-positive—cocci, non-spore-forming bacilli, and spore-forming bacilli (notably the Clostridium spp.); (2) Gram-negative—cocci and bacilli. Many anaerobic bacteria possess virulence factors that facilitate their pathogenicity (e.g. histolytic enzymes and various toxins). A putrid odour of the affected tissue or drainage is highly suggestive of an anaerobic infection, as is the presence of gas in tissues. Aside from supportive care, treatment requires drainage of abscesses and resection of devitalized tissue; and antibiotics—agents that are active against anaerobes include clindamycin, metronidazole, vancomycin, β‎-lactam/β‎-lactamase inhibitor combinations, carbapenems, moxifloxacin, tigecycline, chloramphenicol, and even macrolides.

Abstract:
Previous studies have shown that packaging design can influence people’s expectations regarding product attributes. This study explored the role of packaging visual design in presenting a nonvisual attribute (i.e. odor) by investigating consumers’ responses to various graphic designs displayed on perfume packaging. Particularly, the aim was to examine how different visual elements (such as patterns, photographs and illustrations) influence product choices, preferences and odor associations. 136 people participated in the study, with approximately equal numbers of males and females. They were presented with 10 packaging samples. The samples were of the same shape and size but with different visual elements. The results of the experiment confirmed that participants associated highly recognizable objects with their specific odors. For example, a lemon pattern was paired with a fresh smell, and an image of a rose was paired with a floral smell. On the other hand, when packaging presented odor-neutral objects, the participants’ responses were not uniform. The design which was associated with the largest range of smells was the one with a photograph of a human body, which was paired with three different perfume types (namely, floral, woody and oriental). When data were split by gender, the results suggested that men had a preference for regular and sharp visual shapes. Another relevant finding is that perception of perfume packaging can be influenced by age. Young participants mostly preferred abstract visual shapes for perfume presentations. The results of the choice task indicated that young participants were more sensitive to variations in design than mature participants. Furthermore, they associated most of the packaging designs with more than one type of smell. The findings can be useful for successful perfume packaging design, especially when young consumers are the main target audience.

Abstract:
Introdução: A aromaterapia é um termo designado pela área da fitoterapia empregada desde o ano de 1910, onde se utiliza óleos essenciais (OE) que proporcionam odor agradável, visando o tratamento de indisposições mentais e/ou físicas, que podem ser desencadeados por vários fatores, tais como depressão, ansiedade e insônia. Atualmente essas doenças são mais prevalentes no Brasil, com elevado uso farmacológico e que, geralmente, proporcionam intensos efeitos adversos. Por conta disso, vários estudos sugerem a aromaterapia como tratamento complementar, por proporcionar um equilíbrio físico, mental e emocional, através de OE extraídos de sementes, raízes, talos, cascas, madeiras, flores, folhas e frutos. O uso de OE pode ser por administração tópica (massagens, banhos, compressas), ingestão e inalação. Em decorrência das doenças mencionadas, o óleo de lavanda (OL) é o maisindicado, pois promove um efeito calmante e relaxante, devido à biossíntese de algumas substâncias. Objetivo: Estudar a eficácia da aromaterapia com o uso do OL para o tratamento de ansiedade. Material e métodos: O estudo foi realizado a partir de revisões sistemáticas, de aproximadamente 40 artigos nas plataformas: SciELO, PubMed, Lilacs e outras. Os resultados foram divulgados em palestras ministradas para as turmas do curso de farmácia da Universidade Estadual de Goiás, na unidade de Itumbiara-GO. Resultados: Através do levantamento bibliográfico, observou-se que o OL é eficaz devido à presença de linalol (compõe em torno de 20 a 50% do OL) e acetato de linalina (de 25 a 46%), que estimulam o sistema nervoso parassimpático. O linalol, responsável pelas propriedades ansiolíticas, sedativas e anticonvulsivantes, e o acetato de linalila, que possui efeitos narcóticos. Compostos de menores concentrações, como terpine-4-oll, também constitui OL e auxiliam no tratamento clínico da ansiedade. Além disso, os estudos afirmam que as propriedades terapêuticas, decorrente das substâncias citadas, pode ser influenciada pela genética e pelo ambiente onde a lavanda é cultivada. Conclusão: O uso do OL é uma terapia atual e complementar ao tratamento farmacológico para a ansiedade, demonstrando eficácia e segurança, quando ministrados por profissionais habilitados. Mesmo assim, ainda é necessário realizar estudos que complementam as informações químicas e terapêuticas sobre o OL.
