Finally, participants whose DMPFC activity closely matched that of the average conservative or the average liberal participant were more likely to change their attitudes in the direction of that group's position. Our work introduces a multimethod approach to study the neural basis of political cognition in naturalistic settings. Using this approach, we characterize how political attitudes biased information processing in the brain, the language most likely to drive polarized neural responses, and the consequences of biased processing for attitude change. Together, these results shed light on the psychological and neural underpinnings of how identical information is interpreted differently by conservatives and liberals.Hosts and pathogens are engaged in a continuous evolutionary struggle for physiological dominance. A major site of this struggle is the apoplast. In Phytophthora sojae-soybean interactions, PsXEG1, a pathogen-secreted apoplastic endoglucanase, is a key focal point of this struggle, and the subject of two layers of host defense and pathogen counterdefense. Here, we show that N-glycosylation of PsXEG1 represents an additional layer of this coevolutionary struggle, protecting PsXEG1 against a host apoplastic aspartic protease, GmAP5, that specifically targets PsXEG1. This posttranslational modification also attenuated binding by the previously described host inhibitor, GmGIP1. N-glycosylation of PsXEG1 at N174 and N190 inhibited binding and degradation by GmAP5 and was essential for PsXEG1's full virulence contribution, except in GmAP5-silenced soybeans. Silencing of GmAP5 reduced soybean resistance against WT P. Avasimibe mouse sojae but not against PsXEG1 deletion strains of P. sojae. The crucial role of N-glycosylation within the three layers of defense and counterdefense centered on PsXEG1 highlight the critical importance of this conserved apoplastic effector and its posttranslational modification in Phytophthora-host coevolutionary conflict.

Oxygen administration is recommended for patients with hypoxemia to achieve a target [Formula see text] range. Strategies to achieve this in clinical practice are suboptimal. We investigated automatic oxygen titration using a novel nasal high-flow device with closed-loop oxygen control. The objective of this proof-of-concept study was to determine whether closed-loop control was able to respond to desaturation and subsequent recovery in a controlled laboratory-based environment.

We conducted a single-blind randomized crossover trial in adults with chronic respiratory disease who had a resting [Formula see text] ≥ 92% and desaturated to < 90% during a 6-min walk test (6MWT). Nasal high-flow was administered during a 6MWT and a subsequent 10-min rest period with either room air, a fixed concentration of 28% oxygen, or oxygen titrated automatically using closed-loop control.

The study involved 42 subjects. Closed-loop control maintained [Formula see text] within the target range of 92-96% for a mean (SDation and subsequent recovery.

This study provides proof-of-concept evidence that the novel nasal high-flow device with closed-loop control can respond to changes in [Formula see text] outside a target saturation range using a model of exercise-induced desaturation and subsequent recovery.

The ratio of dead space to tidal volume (V

/V

) is a clinically relevant parameter in ARDS; it has been shown to predict mortality, and it determines the extent to which extracorporeal CO

removal reduces tidal volume (V

) and driving pressure (ΔP). V

/V

can be estimated with volumetric capnography, but empirical formulas using demographic and physiological information have been proposed to estimate V

/V

without the need of additional equipment. It is unknown whether estimated and measured V

/V

produce similar estimates of the predicted effect of extracorporeal CO

removal on ΔP.

We performed a secondary analysis of data from a previous clinical trial including subjects with ARDS in whom V

/V

and CO

production ([Formula see text]) were measured with volumetric capnography. The estimated ratio of dead space to tidal volume (V

/V

) was calculated using standard empiric formulas. Agreement between measured and estimated values was evaluated with Bland-Altman analysis. Agreement between timilar when computed from either estimated or measured V

/V

.

VD/VT and VD,est/VT showed low levels of agreement and cannot be used interchangeably in clinical practice. Nevertheless, the predicted decrease in ΔP due to extracorporeal CO2 removal was similar when computed from either estimated or measured VDalv/VT.

Mechanical insufflation-exsufflation (MI-E) applied via tracheostomy tubes in patients with amyotrophic lateral sclerosis (ALS) who are on home mechanical ventilation via tracheostomy is an effective procedure for respiratory secretion management. Nonetheless, tenacious secretions may remain and increase the risk of respiratory infections. The aim of this study was to determine whether adding oscillations to MI-E could reduce the rate of respiratory infections and the need for bronchoscopy to remove secretions in patients with ALS on home mechanical ventilation via tracheostomy.

This was a 2-y, prospective, crossover study. Subjects were treated with conventional MI-E and MI-E with oscillations for 2 alternate 6-month periods. Data were collected on episodes of respiratory infections, hospital admission, and number of bronchoscopy procedures.

In the 19 ALS subjects enrolled, the median (interquartile range [IQR]) number of acute respiratory infections per subject was 1.0 (0.5-2.0) in the MI-E period and 0.0 (0.0-2.0) in the MI-E plus oscillations period (

= .92). The median (IQR) number of hospital stays was 0.0 (0.0-1.0) in the MI-E period and 0.0 (0.0-1.0) in the MI-E plus oscillations period (

= .80). The median (IQR) number of bronchoscopies per subject was 0.0 (0.0-1.0) in MI-E period and 0.0 (0.0-0.5) in the MI-E plus oscillations period (

= .26). MI-E plus oscillations treatment had no impact on the risk of respiratory infections (odds ratio 3.71, 95% CI 0.81-16.84,

= .09) or the need for bronchoscopy (odds ratio 2.70, 95% CI 0.44-16.68,

= .29).

Adding oscillations to MI-E therapy in subjects with ALS on home mechanical ventilation via tracheostomy did not decrease the risk of respiratory infections, hospital admission, or need for bronchoscopy.
