Effects of methylphenidate on sensitivity to reinforcement delay, magnitude, and probability: Implications for impulsive and risky choice.

Under rapid-acquisition, concurrent-chains choice procedures, psychomotor stimulants typically decrease the sensitivity of responding to changes in separate dimensions of reinforcement. Across two experiments, pigeons chose between outcomes that differed in terms of reinforcement delay and magnitude (the dimensions involved in delay discounting or "impulsive" choice; Experiment 1) or reinforcement probability and magnitude (the dimensions involved in probability discounting or "risky" choice; Experiment 2). Outcomes associated with each terminal link were varied independently and pseudorandomly across sessions such that in dominated sessions one terminal link was favorable in terms of both dimensions (sooner, larger in Experiment 1 and more likely, larger in Experiment 2) and in trade-off sessions each terminal link was favorable in terms of a different dimension.

Distinct CD8 T-cell types Associated with COVID-19 Severity in Unvaccinated HLA-A2 Patients.

Although emerging data have revealed the critical role of memory CD8 T cells in preventing and controlling SARS-CoV-2 infection, virus-specific CD8 T-cell responses against SARS-CoV-2 and its memory and innate-like subsets in unvaccinated COVID-19 patients with various disease manifestations in an HLA-restricted fashion remain to be understood. Here, we show the strong association of protective cellular immunity with mild COVID-19 and unique cell types against SARS-CoV-2 virus in an HLA-A2 restricted manner. ELISpot assays reveal that SARS-CoV-2-specific CD8 T-cell responses in mild COVID-19 patients are significantly higher than in severe patients, whereas neutralizing antibody responses against SARS-CoV-2 virus significantly correlate with disease severity.
