Neural processing of auditory stimuli in rats: Translational aspects using auditory oddball paradigms.

Background: The three-class oddball paradigm allows to investigate the processing of behaviorally relevant and irrelevant auditory stimuli. In humans, event-related potentials (ERPs) are used as neural correlate of behavior. We recorded local field potentials (LFPs) within the medial prefrontal cortex (mPFC) in rats during three-class and passive two-class oddball paradigms and analyzed the ERPs focusing on similarities to human recordings.

Illusion, dilution, or loss: psychological ownership and GenAI.

Generative artificial intelligence (GenAI) reshapes and challenges psychological ownership of created content. This article examines how GenAI disrupts original content creators' and GenAI users' sense of ownership and control and illustrates how both can perceive the illusion, dilution, and potential loss of control and ownership of content in the GenAI era.

Hemorrhagic PitNets Are Associated with Previous Vascular Events and Result in Worse Endocrine Outcome.

Background: Pituitary apoplexy is a potentially life-threatening condition that most often results from hemorrhage into a preexisting pituitary neuroendocrine tumor (PitNet) presenting with acute headache, visual impairment and endocrine dysfunction. Here, we aimed to identify factors associated with hemorrhage and present the pituitary hormonal status before and after transnasal-transsphenoidal tumor removal in a comparative study design.

Methods: A series of 100 patients with PitNet were analyzed.

Associations of pulmonary microvascular blood volume with per cent emphysema and CT emphysema subtypes in the community: the MESA Lung study.

Background: Pulmonary microvasculature alterations are implicated in emphysema pathogenesis, but the association between pulmonary microvascular blood volume (PMBV) and emphysema has not been directly assessed at scale, and prior studies have used non-specific measures of emphysema.

Methods: The Multi-Ethnic Study of Atherosclerosis Lung Study invited participants recruited from the community without renal impairment to undergo contrast-enhanced dual-energy CT. Pulmonary blood volume was calculated by material decomposition; PMBV was defined as blood volume in the peripheral 2 cm of the lung.

Lung structure and longitudinal change in cardiac structure and function: the MESA COPD Study.

Background: Lung structure and cardiac structure and function are associated cross-sectionally. The classic literature suggests relationships of airways disease to cor pulmonale and emphysema to reduced cardiac output (CO) but longitudinal data are lacking.

Methods: The Multi-Ethnic Study of Atherosclerosis (MESA) COPD Study was a multicentre longitudinal COPD case-control study of participants 50-79 years with ≥10 pack-years smoking without clinical cardiovascular disease.
