Multi-Modal Effects of the Repellent Deet Across Protostomia
<p>DEET (N, N-diethyl-m-toluamide) is the most broadly effective and widely used personal repellent available, yet we do not understand what makes it so effective. Even in well-studied species like Drosophila melanogaster flies and Aedes aegypti mosquitoes, many mysteries remain as to how DEET can …

A Computational Analysis of the Gradient Concentration Profile of DEET and the Mosquito Behavioral Response
<p>DEET is a common active ingredient in most spatial repellents. DEET is also a volatile organic compound. DEET prevents mosquitoes from detecting and coming into contact with an human individual. Gas sensing technologies such as metal oxide semiconductor sensors can detect VOCs. The World Health …

A novel encapsulation favorably modifies the skin disposition of topically-applied N,N-diethyl-3-methylbenzamide (DEET)
… insect repellent N,N-diethyl-3-methylbenzamide (DEET) was modified using a unique encapsulation method. Incorporation of DEET into a controlled-release microcapsule facilitated a decrease in skin absorption compared to a DEET in ethanol control while evaporation rates were maintained. Although …

Uso de herramientas ómicas para la evaluación del riesgo ambiental de contaminantes emergentes en especies marinas de interés comercial
… de insectos (N,N-Dietil-meta-toluamida (DEET)) y un biocida (triclosán (TCS)) en dos especies marinas de interés comercial, la dorada (Sparus aurata) y la almeja japonesa (Ruditapes philippinarum). Adicionalmente se realizaron estudios de bioconcentración y toxicocinética. Primero, se …

Chemical Manipulation of Honey Bee Behavior
… be repelled from pesticide-treated crops using DEET and bee pheromonal compounds. Here, I report the toxicological and deterrent effects of bee pheromonal compounds, as well as the deterrent effects of heterocyclic amines (HCAs) on bees. The results of this study indicate that the bee pheromonal …

Structure-Function Analysis of Insect Olfactory Receptors
… findings, we investigated the mode of action of DEET, the most widely used topical insect repellent, and showed that ORs are among its molecular targets. We demonstrated that DEET suppresses Drosophila food-seeking behavior, modulates OSN activity, and decreases OR-mediated currents in …

Factors influencing arbovirus transmission: vector competence and the effects of virus infection on repellent response, oxidative stress, and glutathione-S-transferase activity
… were refractory to low concentrations of DEET, picaridin, and PMD. Increasing concentrations of the repellents to ≥10% was able to increase percent protection (%p) against infected and uninfected mosquitoes. Lastly, we determined the effects of ZIKV and LACV infection on oxidative stress …

Use of Biochar to Produce Reclaimed Water for Irrigation Reuse Purposes
… and Ce/Co ratios. Caffeine, carbamazepine, DEET and PFOA had a greater range of Ce/Co values with highest value >0.5 during continuous adsorption tests and were included in category I compounds. Breakthrough curve predictions revealed that these compounds follow non-linear Thomas model with …

Cells that Kill: The Chemosensory Cell Types of Aedes aegypti Mosquitoes
… legs contributes to contact chemo avoidance of DEET, the principal ingredient in most insect repellents. Moreover, we discovered that the avoidance of DEET is a distinct sensation from the avoidance of bitter, as demonstrated by mosquitoes not being deterred by high concentrations of bitter …

Improved Estimation of Transport Parameters in the Dermis
… of 3 solutes varying in lipophilicity, namely, DEET, diclofenac and parathion. Isolated human dermis obtained from surgical reduction was mounted in side-by-side diffusion cells in the presence and absence of a dialysis membrane (5000 MW cutoff) placed between the dermis and the donor solution. …

Effects of space weathering on the Trojan asteroids
Trojan asteroids orbit at Jupiter's L4 and L5 points. They are included in the D-class of asteroids because of their steep spectral slope. According to spectra of other asteroid classes, the larger the diameter is of a D-class asteroid, the redder the asteroid should be in the visible spectrum. We …

Investigating the role of nonantibiotic chemical contaminants in the evolution of antibiotic resistance
… Paracetamol, benzotriazole, gabapentin, and DEET were detected in the influent with high abundance. The results also revealed that many chemical contaminants, such as fexofenadine, and prometon, had low removal efficiencies. This study suggests the prevalence of chemical contaminants and …

REMOVAL OF EMERGING CONTAMINANTS FROM AQUEOUS SOLUTION BY OZONE -BASED PROCESSES
The presence of emerging contaminants (ECs) in water and wastewater systems has become a subject of significant concern worldwide. These emerging contaminants are complex organic molecules which potentially affect human health and environment. Conventional wastewater treatment plants are unable to …
