Ca excitability of glia to neuromodulator octopamine in Drosophila living brain is greater than that of neurons.

Aim: Octopamine in the Drosophila brain has a neuromodulatory role similar to that of noradrenaline in mammals. After release from Tdc2 neurons, octopamine/tyramine may trigger intracellular Ca signaling via adrenoceptor-like receptors on neural cells, modulating neurotransmission. Octopamine/tyramine receptors are expressed in neurons and glia, but how each of these cell types responds to octopamine remains elusive.

Intron retention of an adhesion GPCR generates 1TM isoforms required for 7TM-GPCR function.

Adhesion G protein-coupled receptors (aGPCRs) are expressed in all organs and are involved in various mechanobiological processes. They are heavily alternatively spliced, forecasting an extraordinary molecular structural diversity. Here, we uncovered the existence of unconventional single-transmembrane (1TM)-containing ADGRL/Cirl proteins devoid of the conventional GPCR layout (i.

Cannabis and alcohol enforcement strategies across the U.S.

Objective: As the legalization of adult-use cannabis has expanded to include almost half of the states in the U.S., substance use-related enforcement responsibilities for state and local law enforcement agencies may have changed.

A Place of Last Drink Initiative: Effects on Various Types of Crime.

Background: Place of last drink (POLD) is a law enforcement strategy designed to decrease the service of alcohol to intoxicated patrons (i.e., overservice).

Odor exposure during imprinting periods increases odorant-specific sensitivity and receptor gene expression in coho salmon (Oncorhynchus kisutch).

Pacific salmon are well known for their homing migrations; juvenile salmon learn odors associated with their natal streams prior to seaward migration, and then use these retained odor memories to guide them back from oceanic feeding grounds to their river of origin to spawn several years later. This memory formation, termed olfactory imprinting, involves (at least in part) sensitization of the peripheral olfactory epithelium to specific odorants. We hypothesized that this change in peripheral sensitivity is due to exposure-dependent increases in the expression of odorant receptor (OR) proteins that are activated by specific odorants experienced during imprinting.
