Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis
FEBS Open Bio, EarlyView.Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

FEBS Open Bio, EarlyView.A novel signature integrating genome‐wide analysis with clinical factors predicts recurrence in stage II colorectal cancer and enables a new risk stratification to guide postoperative adjuvant chemotherapy. Clinical risk stratification for postoperative recurrence in patients with pathological stage II (pStage II) colorectal cancer (CRC) is essential ...

FEBS Open Bio, EarlyView.The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Attempts to establish reliable predictors of journalists’ perceptions of the acceptability of various controversial newsgathering practices such as deception and intrusion have so far produced inconsistent results. This paper proposes an exploratory theoretical model, based on risk-taking theory, which identifies constructs that could be used to ...

Incremental Evaluation of Risky Choices
Journal of the Operational Research Society, 1983This paper compares the incremental method of valuation and its possible effects on choices analysed through utility theory with similar zero-base valuations. Analysis shows how biases can arise using incremental valuations in situations with decreasing risk aversion. This could be important in certain circumstances, e.g.

We present a family of models of choice between behavioural alternatives with stochastic outcomes (risky choice) based on the effects of Weber's Law in memory. These models generalise and extend a model of risk sensitive foraging originally proposed by Reboreda & Kacelnik [(1991) Behav. Ecol.

This paper examines how risk behavior in the limelight differs from that in anonymity. In two separate experiments we find that subjects are more risk averse in the limelight. However, risky choices are similarly path dependent in the different treatments.

Abstract We report evidence of an endowment effect for risk, extending previous results to the popular paired-choice lottery setting. Specifically, we observe a distribution of revealed preferences consistent with risk aversion that diminishes in endowed variance, although the effect is considerably weaker for compound relative to simple lotteries ...

The minority decision — A risky choice
Journal of Experimental Social Psychology, 2015Abstract Objects are evaluated more extremely if they are rare. As minority positions represent low consensus (i.e., only few others agree), they are associated not only with high gains if correct, but also with high losses if wrong. This renders the minority position a risky option.

This chapter connects assumptions about probability distributions, decision makers’ risk attitudes, and the resulting methods used to order risky choices. The methods we discuss are consistent with the expected utility hypothesis because up to this point in time no alternative for decision making under risk has gained widespread acceptance.
