Short-Lived Neutralizing Antibody Responses to Monkeypox Virus in Smallpox Vaccine-Naive Persons after JYNNEOS Vaccination.

JYNNEOS, a third-generation smallpox vaccine, is integral to monkeypox virus (MPXV) control efforts, but the durability of this modified vaccinia Ankara-Bavarian Nordic (MVA-BN) vaccine's effectiveness is undefined. We optimized and used a plaque reduction neutralization test (PRNT) with authentic clade IIa MPXV and vaccinia virus to assess antibody responses over 12 months in 8 donors vaccinated with 2 doses of JYNNEOS. One donor previously received the ACAM2000 vaccine; 7 donors were smallpox vaccine-naive.

Decreased incubation of fentanyl seeking in the absence of proximal drug-paired stimuli.

Treating substance use disorders is difficult as individuals often resume substance use during abstinence. One potential factor contributing to the recurrence of substance use is incubation of drug craving. Specifically, individuals report higher levels of craving when presented with drug-paired stimuli across abstinence, although this effect is largely absent in opioid-dependent individuals.

Poisson Variational Autoencoder.

Variational autoencoders (VAEs) employ Bayesian inference to interpret sensory inputs, mirroring processes that occur in primate vision across both ventral (Higgins et al., 2021) and dorsal (Vafaii et al., 2023) pathways.
