Mode‐of‐Action and Human Relevance Assessment for Diisononyl Phthalate‐Induced Liver Tumors in Rodents

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Diisononyl phthalate (DINP) is a high molecular weight phthalate and high production volume chemical. DINP's carcinogenic potential has been investigated in four rodent bioassays, with liver tumors observed in three of the studies. Authoritative assessments have hypothesized that DINP acts through the peroxisome proliferator‐activated receptor

Multifunctional queen pheromone and maintenance of reproductive harmony in termite colonies. [PDF]

open access: yes, 2012
Pheromones are likely involved in all social activities of social insects including foraging, sexual behavior, defense, nestmate recognition, and caste regulation. Regulation of the number of fertile queens requires communication between reproductive and

Chitosan‐induced modulation of secondary metabolism and stress tolerance in Salvia rosmarinus under combined drought and heat stress

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Abiotic stresses, particularly drought and elevated temperatures, negatively affect plant physiological and metabolic processes. This study investigated the effects of drought, heat, and combined stress on Salvia rosmarinus (rosemary), and evaluated foliar‐applied chitosan as a biostimulant.

Life history and chemical ecology of the Warrior wasp Synoeca septentrionalis (Hymenoptera : Vespidae, Epiponini) [PDF]

open access: yes, 2018
Swarm-founding ‘Warrior wasps’ (Synoeca spp.) are found throughout the tropical regions of South America, are much feared due to their aggressive nest defence and painful sting. There are only five species of Synoeca, all construct distinctive nests that

Systemic Absorption and Pharmacokinetics of Five Novel Topical Dermatologic Agents: A Review

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT In recent years, innovative topical medications with novel mechanisms of action have emerged to treat common dermatologic conditions such as acne, atopic dermatitis, vitiligo, and actinic keratoses. These molecularly targeted therapies offer improved safety and tolerability compared to traditional options like corticosteroids.

Beehavior and Beyond: Realizations in Research [PDF]

open access: yes, 2015
Most people would mistake the small carpenter bee Ceratina calcarata and its relatives for ants with wings,and I won’t pretend that I could tell the difference before I spent a summer researching this particular bee species.

Variation in the level of aggression, chemical and genetic distance among three supercolonies of the Argentine ant in Europe. [PDF]

open access: yes, 2004
In their invasive ranges, Argentine ant populations often form one geographically vast supercolony, genetically and chemically uniform within which there is no intraspecific aggression.

Identification of Orius spp. by Cuticular Hydrocarbons.

open access: yesJapanese Journal of Applied Entomology and Zoology, 2001
Orius spp. are promising natural enemies for control of thrips, harmful insect pests of vegetables. It is, however, extremely difficult to identify adult females of Orius spp. by their appearance. The composition of cuticular hydrocarbons in O. strigicollis, O. minutus and O. sauteri were analyzed by GC-MS. Major components were C27:1 and 2-MeC28 for O.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Genetic and environmental variation impact the cuticular hydrocarbon metabolome on the stigmatic surfaces of maize

open access: yesBMC Plant Biology, 2019
Background Simple non-isoprenoid hydrocarbons accumulate in discrete regions of the biosphere, including within bacteria and algae as a carbon and/or energy store, and the cuticles of plants and insects, where they may protect against environmental ...
