Sinha, Meetali published the artcileGenotoxicity QSAR (Geno-QSAR) models for the safety prioritization of specialty chemicals, Recommanded Product: Benzyl acetate, the main research area is genotoxicity quant structure activity relationship safety.

Toxicity profiling of specialty chems. is essential, since several studies have reported their role in acute/chronic health effects. It is voluminous to perform a battery of toxicity experiments on available specialty chems. In this study, we employed robust QSAR approaches to predict the carcinogenicity and mutagenicity potential for a dataset of 131 specialty chems. utilizing machine learning tools. Four predictive approaches were selected to benchmark the reliability and applicability of the suitable genotoxicity QSAR (Geno-QSAR) models each for carcinogenicity (CAESAR, ISS, ANTARES, and ISSCAN) and mutagenicity (CAESAR, SARpy, ISS, and KNN). Five-fold statistical evaluation was performed using an external dataset of more than 2000 compounds with their known genotoxicity potential. KNN/Read across and IRFMN/ANTARES resulted as the best model for mutagenicity and carcinogenicity, resp. Results obtained from the selected predictive models are narrowed down to the potentially safe compounds and are cross-validated with the exptl. details compiled through the literature mining. Geno-QSAR approaches demonstrated in this investigation have widespread applicability for safe compound prioritization and toxicity prediction of a large number of chems. in a lucid way.

Guleria, Niraj published the artcileIdentification of male-specific active host plant volatiles for maize stem borer, Chilo partellus swinhoe, HPLC of Formula: 140-11-4, the main research area is male specific host plant volatiles maize stem borer Chilo.

The present study was conducted to identify male-specific active plant volatiles from maize against Chilo partellus. The gas chromatog.-electroantennogram detector evaluation of volatile extracts collected from maize plant through dynamic headspace collection revealed the presence of six electrophysiol. active volatiles for male, viz. toluene, 2-ethyl-1-hexanol, 4- hydroxy-4-methyl-2-pentanone, 1,4-dichlorobenzene, p- iso-Pr benzaldehyde (cuminaldehyde) and p-xylene. Electroantennogram anal. of selective synthetic volatiles against male moths revealed significantly higher response to geranyl acetate, cuminaldehyde, linalool and 2-ethyl-1-hexanol. Electroantennogram studies showed dose-dependent responses of male moths against geranyl acetate, cuminaldehyde, linalool and 2-ethyl-1-hexanol up to 50μg, above which saturation of antennal response was noticed. These findings will help to study the synergistic activity of identified volatiles with pheromone compounds for developing more effective lure for C. partellus monitoring and mass trapping.

Sendel, Sebastian published the artcileVolatile organic compounds released by wheat as a result of striped shieldbug feeding and insect behaviour, COA of Formula: C9H10O2, the main research area is volatile organic compound wheat shieldbug feeding insect behavior.

The most popular plant protection method is chem.; however, this is often connected with repeated treatments. Therefore, eco-friendly strategies need to be investigated. A good alternative is to use the natural repellent properties of plants. The aims of this study were to determine how adult striped shieldbugs (Aelia acuminata L.) feeding on spring wheat plants affect the emission of volatile organic compounds (VOCs) and to determine the reaction of these insects to synthetic blends of VOCs. Using GC/MS for VOC anal., we find that Aelia acuminata L. (1 or 2 adult pairs) significantly induced VOC emissions from wheat plants. In comparison with controls, larger amounts of (Z)-3-hexenal, (E)-2-hexenal, (Z)-3-hexen-1-ol, (E)-2-hexen-1-ol, β-pinene, β-myrcene, (Z)-3-hexen-1-yl acetate, 1-hexyl acetate, 4-heptanone, (Z)-ocimene, linalool, linalool oxide, benzyl acetate, Me salicylate, indole, β-caryophyllene and (E)-β-farnesene were released as a result of the biotic stress, with two pairs of insects causing a significantly stronger plant reaction. On the basis of the VOCs identified and their emitted concentrations for two pairs of feeding adult striped shieldbugs, two blends of VOCs were prepared in three concentrations: blend I-(Z)-3-hexenal, (E)-2-hexenal, (Z)-3-hexen-1-ol, (E)-2-hexen-1-ol, (Z)-3-hexen-1-yl acetate and 1-hexyl acetate, and blend II-(Z)-ocimene, linalool, benzyl acetate, Me salicylate, β-caryophyllene and (E)-β-farnesene. Using an olfactometer (Y-tube) to study insect behavior, it was found that the male striped shieldbugs were not attracted to any of the blends at any concentration Female shieldbugs were attracted to blend I at concentration 1. As for the remaining concentrations of both blends, females and males were repelled, with the higher the concentration the stronger the insect reaction.

Braunschmid, Herbert published the artcileFloral scent and pollinators of Cypripedium calceolus L. at different latitudes, Name: Benzyl acetate, the main research area is Cypripedium pollinator floral scent.

Floral scent is an important trait in plant-pollinator interactions. It not only varies among plant species but also among populations within species. Such variability might be caused by various non-selective factors, or, as has been shown in some instances, might be the result of divergent selective pressures exerted by variable pollinator climates. Cypripedium calceolus is a Eurasian deceptive orchid pollinated mainly by bees, which spans wide altitudinal and latitudinal gradients in mainly quite isolated populations. In the present study, we investigated whether pollinators and floral scents vary among different latitudes. Floral scents of three C. calceolus populations in the Southern Alps were collected by dynamic headspace and analyzed by gas chromatog. coupled to mass spectrometry (GC/MS). These data were completed by previously published scent data of the Northern Alps and Scandinavia. The scent characteristics were compared with information on pollinators recorded for present study or available in the literature. More than 80 scent compounds were overall recorded from plants of the three regions, mainly aliphatics, terpenoids, and aromatics Seven compounds were found in all samples, and most samples were dominated by linalool and octyl acetate. Although scents differed among regions and populations, the main compounds were similar among regions. Andrena and Lasioglossum species were the main pollinators in all three regions, with Andrena being relatively more abundant than Lasioglossum in Scandinavia. We discuss natural selection mediated by pollinators and neg. frequency-dependent selection as possible reasons for the identified variation of floral scent within and among populations and regions.

Xiao, Zuobing published the artcileIdentification of key aromas of Chinese muskmelon and study of their formation mechanisms, Synthetic Route of 140-11-4, the main research area is Chinese muskmelon formation mechanism key aroma identification.

The volatile compounds found in melons (Cucumis melo L.) obtained from three cultivars [Jiashi (JS), Xizhoumi17 (XZM) and Minqin (MQ)] were comprehensively analyzed by gas chromatog.-olfactometry (GC-O), gas chromatog.-mass spectrometry (GC-MS), and GC-flame photometric detection (GC-FPD). The result showed that 46, 45 and 69 volatile compounds were detected in XZM, JS and MQ samples by GC-MS, resp. Besides, 6, 8 and 9 sulfur compounds were detected by GC-FPD, resp. Di-Me sulfide, 1-propanethiol, 3-mercapto-3methylbutanol, 3-methyl-2-buten-1-thiol were detected for the first time in melon. 25 key aroma compounds were identified in MQ muskmelon by omission tests, among which (Z)-6-nonenal, (Z)-6-nonen-1-ol, 3-methylbutanal, 2-methylbutyl acetate, hexanal and Me thioacetate were particularly important. The interaction between three aroma compounds containing nine-carbon straight-chain structure and five thioesters in MQ muskmelon was studied by comparing their olfactory threshold and OAV values. Among the 18 binary mixtures, 8 mixtures showed a synergistic effect, 2 mixtures presented an additive effect, 2 mixtures showed no interaction, 6 mixtures exhibited a masking effect. There is a synergistic effect between (Z)-6-nonenal, (Z)-6-nonen-1-ol and (E, Z)-3,6-nonadien-1-ol, the aroma intensity of the mixture can be predicted by modified vector model.

Gonzalez Flores, Melisa published the artcileEvaluation of cryotolerant yeasts for the elaboration of a fermented pear beverage in Patagonia: Physicochemical and sensory attributes, HPLC of Formula: 140-11-4, the main research area is cryotolerant yeast fermented pear beverage sensory physicochem property; Fermentation; Patagonia; Pear; Saccharomyces uvarum; Sensory analysis; Sorbitol.

The production of pome fruits as pears and apples, as well as their derived industries, is of great economic importance in North Patagonia. The elaboration of fermented beverages as cider or perry has evidenced a substantial diversification during the last years, with the evaluation of different fruit varieties, yeast starters and technol. changes. In this work, two cryotolerant yeasts belonging to the species Saccharomyces uvarum were evaluated at laboratory and pilot scale in sterile and no-sterile pear must. One of the strains was originally isolated from apple chicha (strain NPCC1314) and the other from apple cider (strain NPCC1420) in Patagonia. Both physicochem. and sensory features of the fermented products were evaluated. Both strains were able to successfully complete the fermentations, although strain NPCC1420 showed the better kinetic properties including a faster sugar consumption than the strain NPCC1314. Both strains showed excellent implantation capacity, but the fermented products showed different chem. profiles. The perry fermented with the strain NPCC1314 was characterized by better sensory attributes as assessed by trained panelists and a greater acceptance for untrained public than the same fermented with the strain NPCC1420. The two strains were able to consume sorbitol, both in pear must and in agar-plates supplemented with sorbitol as the sole carbon source. This ability is described for the first time in S. uvarum, at least for the two strains evaluated in this work.

Bera, Paramita published the artcileDevelopmental variation in floral volatiles composition of a fragrant orchid Zygopetalum maculatum (Kunth) Garay, Synthetic Route of 140-11-4, the main research area is Zygopetalum volatile; (Kunth) Garay; benzenoids; headspace scent volatiles; phenylpropanoid.

Emitted scent volatile profile of an orchid species Zygopetalum maculatum was studied using dynamic headspace sampling technique with four different adsorbent matrixes, namely Porapak Type Q polymer (mesh size: 80/100), Tenax (mesh size: 60/80), activated charcoal and graphite. In addition, developmental variations in scent emissions and endogenous volatile levels were also investigated. Gas chromatog.-mass spectrometry anal. revealed the presence of 21 volatile compounds in the headspace, which was predominantly enriched with benzenoid compounds Among these benzenoids, o-diethylbenzene and p-diethylbenzene were the major compounds followed by benzyl acetate and Me salicylate. Among the phenylpropanoid compounds, 2-phenylethyl acetate was the major volatile. However, as compared to benzenoids, the quantity was much lesser, indicating the inclination of phenylalanine flux towards benzenoid pathway. The outcome of this study has the implications in enhancing fragrance and vase life of orchids of the Sikkim Himalaya region and thus may further help to meet the growing market demand.

Aniceto, Jose P. S. published the artcileMachine learning models for the prediction of diffusivities in supercritical CO2 systems, Application of Benzyl acetate, the main research area is carbon dioxide supercritical system machine learning diffusivity.

The mol. diffusion coefficient is fundamental to estimate dispersion coefficients, convective mass transfer coefficients, etc. Since exptl. diffusion data is scarce, there is significant demand for accurate models capable of providing reliable diffusion coefficient estimations In this work we applied machine learning algorithms to develop predictive models to estimate diffusivities of solutes in supercritical carbon dioxide. A database of exptl. data containing 13 properties for 174 binary systems totaling 4917 data points was used in the training of the models. Five machine learning algorithms were evaluated and the results were compared with three commonly used classic models. The best results were found using the Gradient Boosted algorithm which showed an average absolute relative deviation (AARD) of 2.58% (pure prediction). This model has five parameters: temperature, d., solute molar mass, solute critical pressure and solute acentric factor. For the same dataset, the classic Wilke-Chang equation showed AARD of 12.41%. The developed model is provided as command line program.

Roda, Amy published the artcileA new synthetic lure for management of the invasive giant African snail, Lissachatina fulica, COA of Formula: C9H10O2, the main research area is Lissachatina lure fruit flavor oil volatile compound biocontrol.

The goal of this study was to find a synthetic attractant that could aid in the eradication or management of the giant African snail (Lissachatina fulica). Field studies in Hawaii showed that a com. papaya-flavored oil attracted snails. Anal. of the odor profile of the oil identified a total of 22 chems., which comprised > 98% of the volatile compounds emitted by the oil. A synthetic blend was reconstructed that mirrored the release rates of the papaya oil odors. In laboratory and field bioassays, the reconstructed blend, applied to cotton wicks as water and canola oil or water and mineral emulsions, attracted more snails than the water and oil emulsion control wicks. Field studies in Hawaii and Florida showed that the reconstructed blend in an oil emulsion was not attractive to non-target species such as butterflies or bees. The snails were attracted from distances > 1 m and entered traps baited with the attractant emulsion. When tested in the South Florida giant African snail eradication program, direct ground application of the reconstructed papaya-flavored oil emulsion increased the number of snails killed by over 87% compared to water emulsion controls. Integrating tactics using the synthetic papaya oil attractant into control measures should increase the effectiveness of eradication and management programs.

Nagy, Antal published the artcileAddition of 4-oxoisophorone improves performance of bisexual lure for Autographa gamma (L.) (Lepidoptera: Noctuidae), Application In Synthesis of 140-11-4, the main research area is oxoisophorone phenylacetaldehyde benzyl acetate eugenol Autographa.

In field trapping tests the addition of 4-oxoisophorone (2,6,6-trimethylcyclohex-2-ene-1,4-dione) to the known ternary bisexual lure (consisting of phenylacetaldehyde + benzyl acetate + eugenol) significantly increased catches of the silver Y moth Autographa gamma, an important migratory noctuid pest. Both female and male moths were attracted, supposedly in the natural sex ratio of the local population. Traps baited with the quaternary lure caught 27.9% of the number of moths in traps baited with synthetic sex pheromone (all males), and the two types of lures showed similar seasonal trends when following the quant. changes in moth flight throughout the whole season. This suggests that the improved quaternary bisexual lure could be efficient enough to yield a new tool for detection and monitoring of A. gamma, resulting in more reliable plant protection decisions based on female catches, and can provide data for studies where the catch of females and data on sex ratio are indispensable.
