A Qualitative Analysis of Ethical Perspectives on Recruitment and Consent for Human Intracranial Electrophysiology Studies.

Intracranial electrophysiological research methods, including those applying electrodes on the cortical surface or in deep structures, have become increasingly important in human neuroscience. They also pose novel ethical concerns, as human studies require the participation of neurological patients undergoing surgery for conditions such as epilepsy and Parkinson's disease. Research participants in this setting may be vulnerable to conflicts of interest, therapeutic misconception, and other threats to valid recruitment and consent.

Reliability of sagittal vertical axis measurement and association with measures of age-related hyperkyphosis.

[Purpose] Persons with age-related hyperkyphosis often have concomitant sagittal plane imbalance of the spine. This study investigated the reliability of sagittal vertical axis (SVA) measurement of sagittal balance, association between thoracic Cobb angle of kyphosis and SVA measure of sagittal balance, and compared the degree of SVA in males and females with age-related hyperkyphosis. [Participants and Methods] Measurements of SVA and Cobb angle of kyphosis were obtained from baseline radiographs of 112 community-dwelling males and females, mean age 70.

Comparative assessment of fluorescent transgene methods for quantitative imaging in human cells.

Fluorescence tagging of proteins is a widely used tool to study protein function and dynamics in live cells. However, the extent to which different mammalian transgene methods faithfully report on the properties of endogenous proteins has not been studied comparatively. Here we use quantitative live-cell imaging and single-molecule spectroscopy to analyze how different transgene systems affect imaging of the functional properties of the mitotic kinase Aurora B.

Empathy in children with autism and conduct disorder: group-specific profiles and developmental aspects.

Background:   A deficit in empathy is discussed to underlie difficulties in social interaction of children with autism spectrum disorder (ASD) and conduct disorder (CD). To date, no study has compared children with ASD and different subtypes of CD to describe disorder-specific empathy profiles in clinical samples. Furthermore, little is known about age influences on the development of empathic skills.
