NeuroImage

Li JM, Acland BT, Brenner AS, Bentley WJ, Snyder LH.
PMID: 34923136
Neuroimage. 2021 Dec 16;118728. doi: 10.1016/j.neuroimage.2021.118728. Epub 2021 Dec 16.

Resting-state functional MRI (rsfMRI) provides a view of human brain organization based on correlation patterns of blood oxygen level dependent (BOLD) signals recorded across the whole brain. The neural basis of resting-state BOLD fluctuations and their correlation remains poorly...

Genetic basis of offspring number-body weight tradeoff in Drosophila melanogaster.

G3 (Bethesda). 2021 Apr 19; doi: 10.1093/g3journal/jkab129. Epub 2021 Apr 19.

Drosophila melanogaster egg production, a proxy for fecundity, is an extensively studied life-history trait with a strong genetic basis. As eggs develop into larvae and adults, space and resource constraints can put pressure on the developing offspring, leading to...

Thioesterase enzyme families: functions, structures, and mechanisms.

Protein science : a publication of the Protein Society

Caswell BT, de Carvalho CC, Nguyen H, Roy M, Nguyen T, Cantu DC.
PMID: 34921469
Protein Sci. 2021 Dec 18; doi: 10.1002/pro.4263. Epub 2021 Dec 18.

Thioesterases are enzymes that hydrolyze thioester bonds in numerous biochemical pathways, for example in fatty acid synthesis. This work reports known functions, structures, and mechanisms of updated thioesterase enzyme families, which are classified into thirty-five families based on sequence...

Longitudinal Coupling of Depression in Parent-Adolescent Dyads: Within- and Between-Dyad Effects Over Time.

Clinical psychological science : a journal of the Association for Psychological Science

Griffith JM, Young JF, Hankin BL.
PMID: 35003905
Clin Psychol Sci. 2021 Nov 01;9(6):1059-1079. doi: 10.1177/2167702621998313. Epub 2021 Apr 28.

The present work evaluated reciprocal, within-dyad associations between parent-adolescent depressive symptoms across two independent samples (N=327 and N=435 dyads, respectively; approximately 85% biological mothers) assessed every three months for two (Study 1) to three (Study 2) years. Results of...

Type of bony involvement predicts genomic subgroup in sphenoid wing meningiomas.

PURPOSE: As sphenoid wing meningiomas (SWMs) are associated with varying degrees of bony involvement, we sought to understand potential relationships between genomic subgroup and this feature.METHODS: Patients treated at Yale-New Haven Hospital for SWM were reviewed. Genomic subgroup was...

Impact of surface free energy on electrostatic extraction of particles from a bed.

Journal of colloid and interface science

Lobel BT, Robertson H, Webber GB, Ireland PM, Wanless EJ.

HYPOTHESIS: Electrostatic extraction of particles from a bed to a pendent droplet to form liquid marbles has previously been investigated with respect to particle conductivity, size and shape, however, interparticle forces have not been specifically interrogated. If cohesion is...

Performance of specific morphologic features in distinguishing low-grade squamous intraepithelial lesions from high-grade squamous intraepithelial lesions in borderline cases: a College of American Pathologists Cytopathology Committee multiobserver study.

Journal of the American Society of Cytopathology

INTRODUCTION: Distinguishing between low-grade squamous intraepithelial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL) can be difficult on certain Papanicolaou (Pap) tests, hindering interobserver concordance. We investigated the variables influencing the interpretation of LSIL versus HSIL in Pap test...
