Host innate immunity is one of the factors that determines the resistance of insects to their entomopathogens. In the research reported here we studied whether or not phenoloxidase (PO), a key enzyme in the melanogenesis component of humoral immunity of insects, plays a role in the protection of Lymantria dispar larvae from infection by L. dispar multiple nucleopolyhedrovirus. We studied two ty...

This paper profiles meta-cognitive (affect-dysregulation, empathy and identity-concerns) and interpersonal difficulties in both overt (ON) and covert (CN) narcissism. It explores mediation effects of meta-cognition in interpersonal difficulties. Participants (n = 177) completed self-report measures of ON and CN, affect-dysregulation, empathy, identity-concerns, and interpersonal difficulties. A...

The neural systems supporting speech and sign processing are very similar, although not identical. In a previous fTCD study of hearing native signers (Gutierrez-Sigut, Daws, et al., 2015) we found stronger left lateralization for sign than speech. Given that this increased lateralization could not be explained by hand movement alone, the contribution of motor movement versus 'linguistic' proces...

Motion visually evoked potentials (mVEPs) have recently been explored as input features for brain-computer interfaces, in particular for the implementation of visual spellers. Due to low contrast and luminance requirements, motion-based intensification is less discomforting to the user than conventional approaches. So far, mVEP spellers were operated in the overt attention mode, wherein eye mov...

This study investigated the relative contributions of overt and covert attention on the apparent anticipatory nature of attention in two experiments, using two different object tracking tasks, both combined with a probe detection task. In Experiment 1, we investigated the distribution of attention for overtly and covertly tracked targets separately at low tracking load using a single-object tra...

Covert face recognition was investigated in a patient with prosopagnosia without object agnosia. This patient performed well in various face processing tasks like expression analysis and feature processing and had relatively preserved semantic knowledge about persons, but was slightly impaired in the visual matching of unfamiliar faces. In face-name paired-associate relearning task, covert face...

Hepatic encephalopathy (HE) is a major complication of liver disease that leads to significant morbidity and mortality. Caring for hospitalized patients with HE is becoming more complex, and the economic burden of HE continues to rise. Defining and diagnosing HE, particularly covert HE (CHE), remain challenging. In this article, we review new tools and those currently under development for the ...
