Individual differences of conflict monitoring and feedback processing during reinforcement learning in a mock forensic context.

This study investigated individual differences of conflict monitoring (N2 component), feedback processing (feedback negativity component), and reinforcement learning in a discrimination learning task using a mock (fictitious) forensic scenario to set participants in a semantic task context. We investigated individual differences of anxiety-related, impulsivity-related traits and reasoning ability during trial-and-error learning of mock suspect and nonsuspect faces. Thereby, we asked how the differential investment of cognitive-motivational processes facilitates learning in a mock forensic context.

The N2 component in a go-nogo learning task: Motivation, behavioral activation, and reasoning.

Although the association of the N2 component with behavioral inhibition (BIS) has regularly been investigated, its association with other personality characteristics remains widely unknown. We investigated the association of the N2 with the sensitivity of the behavioral activation system (BAS). The aim was not to show that the N2 is linked to trait BAS instead of trait BIS, but that a motivating setting may alter its association with those traits.

[Anesthesia in a patient after endoscopic lung volume reduction. First anesthesiological experiences with implanted endobronchial valves].

Chronic obstructive pulmonary disease (COPD) is a disease with a high incidence and extensive comorbidities that make COPD a key challenge for anesthesiologists. A new treatment strategy, such as endoscopic lung volume reduction (ELVR) with implantation of endobronchial valves is a rapidly developing area which is still unknown to many anesthesiologists. This article therefore describes first experiences in a patient with five endobronchial valves in the right upper lobe who needed urgent surgery due to lumbar disc herniation with neurological impairment.

Influence of laser light on bioimplants used in otorhinolaryngology.

In otorhinolaryngology, dermatology and reconstructive surgery biomaterials as implants and a variety of lasers are used. Laser light applied near to an implant could have the risk to damage these materials. Therefore, their resistance exposed to laser light is of interest.

NO-β-catenin crosstalk modulates primitive streak formation prior to embryonic stem cell osteogenic differentiation.

Nitric oxide (NO) has been shown to play a crucial role in bone formation in vivo. We sought to determine the temporal effect of NO on murine embryonic stem cells (ESCs) under culture conditions that promote osteogenesis. Expression profiles of NO pathway members and osteoblast-specific markers were analyzed using appropriate assays.
