Front Chem 2022 26;10:896386. Epub 2022 May 26.

Department of Biochemistry and Molecular Medicine, University of California, Davis, Davis, CA, United States.

Several neurodegenerative diseases are driven by misfolded proteins that assemble into soluble aggregates. These "toxic oligomers" have been associated with a plethora of cellular dysfunction and dysregulation, however the structural features underlying their toxicity are poorly understood. A major impediment to answering this question relates to the heterogeneous nature of the oligomers, both in terms of structural disorder and oligomer size. Read More

Jonghwan Lee

Adv Geriatr Med Res 2022 29;4(1). Epub 2022 Mar 29.

Center for Biomedical Engineering, School of Engineering, Brown University, Providence, RI 02912, USA.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder affecting millions of people worldwide and is currently incurable. As the population ages, AD and related dementia are becoming the biggest epidemic in medical history: the number of people aged 65 and older with AD is projected to increase between two- and three-fold by 2050. Imaging and biomarker studies suggest that the pathophysiological processes of AD begin more than a decade before the diagnosis of dementia, opening the possibility of early, preemptive prediction.

Cognition 2022 Aug 29;225:105103. Epub 2022 Mar 29.

Department of Cognitive, Linguistic, and Psychological Sciences, Brown University, USA; Carney Institute for Brain Science, Brown University, USA.

Humans appear to represent many forms of knowledge in associative networks whose nodes are multiply connected, including sensory, spatial, and semantic. Recent work has shown that explicitly augmenting artificial agents with such graph-structured representations endows them with more human-like capabilities of compositionality and transfer learning. An open question is how humans acquire these representations. Read More

A review of multiomics platforms in pituitary adenoma pathogenesis.

Front Biosci (Landmark Ed) 2022 03;27(3):77

Department of Neurosurgery, University of Utah, Salt Lake City, UT 84132, USA.

Pituitary adenomas (PA), or pituitary neuroendocrine tumors (PitNETs), represent 15% of all central nervous system tumors. Classic description of PitNETs solely by hormonal classification has given way to key transcription factors that play a role in the pathology of PitNETs including steroidogenic factor-1 (SF-1), t-box pituitary transcription factor (TPIT), and pituitary transcription factor 1 (PIT-1). Germline mutations in various familial PitNETs are discussed including those in familial isolated pituitary adenoma (FIPA), multiple endocrine neoplasia (MEN), neurofibromatosis 1 (NF1), and Carney complex.

Time perception in film is modulated by sensory modality and arousal.

Atten Percept Psychophys 2022 Apr 18;84(3):926-942. Epub 2022 Mar 18.

Department of Cognitive, Linguistic, and Psychological Sciences, Brown University, Providence, RI, 02912, USA.

Considerable research has shown that the perception of time can be distorted subjectively, but little empirical work has examined what factors affect time perception in film, a naturalistic multimodal stimulus. Here, we explore the effect of sensory modality, arousal, and valence on how participants estimate durations in film. Using behavioral ratings combined with pupillometry in a within-participants design, we analyzed responses to and duration estimates of film clips in three experimental conditions: audiovisual (containing music and sound effects), visual (without music and sound effects), and auditory (music and sound effects without a visual scene).
