Hypoxic ischemic encephalopathy (HIE) is a brain injury that occurs in 1 ~ 5/1000 term neonates. Accurate identification and segmentation of HIE-related lesions in neonatal brain magnetic resonance images (MRIs) is the first step toward identifying high-risk patients, understanding neurological symptoms, evaluating treatment effects, and predicting outcomes. We release the first public dataset containing neonatal brain diffusion MRI and expert annotation of lesions from 133 patients diagnosed with HIE.

The symptoms of HAE and its impacts on HRQoL have been well-documented in adults; however, relatively little is known about the experiences of adolescents with HAE. The objective of this study was to use qualitative interviews to investigate how adolescents experience HAE symptoms and how HAE impacts their HRQoL.

Methods: This retrospective cohort study examined mental health crisis line calls transferred to active rescue (N=3,538 calls; N=3,132 unique callers) from the Georgia Crisis and Access Line (2016-2018). Chi-square analyses and t tests were used to examine descriptive differences between caller characteristics and call features.
Social learning, where animals learn from other individuals, occurs in many diverse species. The influential but debated 'costly information' hypothesis posits that animals will rely more on social information in high-risk contexts, such as under increased predation risk. We examined and compared the effects of perceived predation risk on social learning of foraging sites in female Trinidadian guppies from wild and domestic populations raised in common-garden environments.

Cyclic di-AMP regulates bacterial cell volume and turgor via control of potassium and compatible solute transport but is also involved in many other processes, including the activation of the metazoan innate immune response to bacterial infections. We compare the activity of full-length membrane-embedded CdaA, the enzyme that synthesizes cyclic di-AMP, with the water-soluble catalytic domain CdaA-DAC.
