p14 forms meso-scale assemblies upon phase separation with NPM1.

NPM1 is an abundant nucleolar chaperone that, in addition to facilitating ribosome biogenesis, contributes to nucleolar stress responses and tumor suppression through its regulation of the p14 Alternative Reading Frame tumor suppressor protein (p14). Oncogenic stress induces p14 to inhibit MDM2, stabilize p53 and arrest the cell cycle. Under non-stress conditions, NPM1 stabilizes p14 in nucleoli, preventing its degradation and blocking p53 activation.

Making the most of errors: Utilizing erroneous classifications generated by machine-learning models of neuroimaging data to capture disorder heterogeneity.

Within-disorder heterogeneity complicates mapping the neurobiological features of psychopathology to Diagnostic and Statistical Manual of Mental Disorders conceptualizations. The present study explored the patterns of diagnostic classification errors among disorders with commonly co-occurring features to examine this heterogeneity. Classification analyses were conducted with the University of California, Los Angeles Phenomics Study database using a support-vector classifier to differentiate disorders via whole brain task-based functional connectivity, predicting that model misclassifications would provide insight about brain connectivity characteristics shared across disorders.

Cultivating emotional resilience in adolescent girls: Effects of a growth emotion mindset lesson.

To address the widespread mental health crisis facing adolescent girls, this study examined whether a growth emotion mindset lesson can enhance emotional competence. During 2018-2022, adolescent girls (M = 15.68 years; 66.

Probing the Distribution and Mobility of Aminopolymers after Multiple Sorption-Regeneration Cycles: Neutron Scattering Studies.

Solid-supported amines are effective CO adsorbents capable of capturing CO from flue gas streams (10-15 vol % CO) and from ultradilute streams, such as ambient air (∼400 ppm CO). Amine sorbents have demonstrated promising performance (e.g.

Underlying Roles of Polyol Additives in Promoting CO Capture in PEI/Silica Adsorbents.

Solid-supported amines having low molecular weight branched poly(ethylenimine) (PEI) physically impregnated into porous solid supports are promising adsorbents for CO capture. Co-impregnating short-chain poly(ethylene glycol) (PEG) together with PEI alters the performance of the adsorbent, delivering improved amine efficiency (AE, mol CO sorbed/mol N) and faster CO uptake rates. To uncover the physical basis for this improved gas capture performance, we probe the distribution and mobility of the polymers in the pores via small angle neutron scattering (SANS), solid-state NMR, and molecular dynamic (MD) simulation studies.
