Effect of acute treatment with the glucagon-like peptide-1 receptor agonist, liraglutide, and estrus phase on cue- and drug-induced fentanyl seeking in female rats.

Opioid use disorder (OUD) is a crisis in the USA. Despite advances with medications for OUD, overdose deaths have continued to rise and are largely driven by fentanyl. We have previously found that male rats readily self-administer fentanyl, with evident individual differences in fentanyl taking, seeking, and reinstatement behaviors.

Would provision of Take Home Naloxone Kits by Emergency Medical Services be perceived as acceptable to people at risk of opioid overdose? A qualitative study.

Objectives: Take home naloxone kits can reduce mortality, but we know little about how they are perceived by people with lived experience of opioid use. Provision of naloxone in the community has been shown to significantly reduce mortality from opioid overdose. Currently, this is predominantly through drug treatment support services but expanding provision through other services might be effective in increasing kit take-up and mortality reduction.

Patient Perceptions of Radiation Therapy Prior to Initial Consultation With a Radiation Oncologist.

Purpose: There are currently limited data regarding patient perceptions and fears related to radiation therapy (RT). This study sought to identify and quantify patient concerns regarding RT and to determine the potential value of assessing these expectations prior to initial consultation.

Methods And Materials: Patients with no prior history of RT were invited to complete an investigator-developed anonymous electronic survey prior to consultation.

Collective oscillatory signaling in Dictyosteliumdiscoideum acts as a developmental timer initiated by weak coupling of a noisy pulsatile signal.

Oscillatory phenomena play widespread roles in the control of biological systems. In D. discoideum, oscillatory cyclic adenosine monophosphate (cAMP) signaling drives collective behavior and induces a temporal developmental gene expression program.

Adapting to time: Why nature may have evolved a diverse set of neurons.

Brains have evolved diverse neurons with varying morphologies and dynamics that impact temporal information processing. In contrast, most neural network models use homogeneous units that vary only in spatial parameters (weights and biases). To explore the importance of temporal parameters, we trained spiking neural networks on tasks with varying temporal complexity, holding different parameter subsets constant.
