    Modulation of sleep by trafficking of lipids through the Drosophila blood-brain barrier

    Fu Li, Gregory Artiushin, Amita Sehgal
    Metabolites, such as acylcarnitines, accumulate in Drosophila heads when endocytosis is blocked and reflects an increased need for sleep.

    Comparable in vivo joint kinematics between self-reported stable and unstable knees after TKA can be explained by muscular adaptation strategies: A retrospective observational study

    Longfeng Rao, Nils Horn ... Pascal Schütz
    Muscle synergies are able to identify muscular adaptation that results from feelings of joint instability, whereas tibiofemoral kinematics are sensitive for detecting acute instability events during functional activities.

    Temporal integration is a robust feature of perceptual decisions

    Alexandre Hyafil, Jaime de la Rocha ... Jonathan W Pillow
    Responses of monkeys, rats, and humans performing perceptual discrimination of discrete-sample stimuli rely on accumulation over time of sensory evidence.

    Scn1a-GFP transgenic mouse revealed Nav1.1 expression in neocortical pyramidal tract projection neurons

    Tetsushi Yamagata, Ikuo Ogiwara ... Kazuhiro Yamakawa
    In neocortex, Nav1.1 is expressed in neocortical pyramidal tract projection neurons and a minor subpopulation of cortico-cortical projection neurons in addition to its predominant expression in inhibitory neurons, while the majority of cortico-thalamic, cortico-striatal, and cortico-cortical neurons express Nav1.2.

    Gene and protein expression and metabolic flux analysis reveals metabolic scaling in liver ex vivo and in vivo

    Ngozi D Akingbesote, Brooks P Leitner ... Rachel J Perry
    Transcriptomic, enzyme activity, and flux data demonstrate that metabolic scaling, the inverse correlation between body size and metabolic rate per gram of tissue, is a conserved phenomenon that occurs at multiple physiological levels and in multiple tissues.

    The fat body cortical actin network regulates Drosophila inter-organ nutrient trafficking, signaling, and adipose cell size

    Rupali Ugrankar-Banerjee, Son Tran ... W Mike Henne
    Fat-body-specific loss of actin isoform Act5C disrupts fat body cell growth and fat storage, lipoprotein secretion, and insulin signaling, revealing a non-canonical role for the cortical actin cytoskeleton in nutrient signaling and inter-organelle trafficking.

    Nationwide participation in FIT-based colorectal cancer screening in Denmark during the COVID-19 pandemic: An observational study

    Tina Bech Olesen, Henry Jensen ... Morten Rasmussen
    The participation in the FIT-based colorectal cancer screening programme and subsequent compliance to colonoscopy after a positive FIT test was only slightly affected during the COVID-19 pandemic in Denmark.

    Endosomal trafficking of two-pore K+ efflux channel TWIK2 to plasmalemma mediates NLRP3 inflammasome activation and inflammatory injury

    Long Shuang Huang, Mohammad Anas ... Asrar B Malik
    Rab11a-mediated endosomal trafficking in macrophages regulates potassium channel localization and activity at the cell surface and the downstream activation of the inflammasome and is a potential therapeutic target in acute or chronic inflammatory states.

    The dark kinase STK32A regulates hair cell planar polarity opposite of EMX2 in the developing mouse inner ear

    Shihai Jia, Evan M Ratzan ... Michael R Deans
    The planar polarized organization of vestibular hair cells in the mouse inner ear is determined by the coordinated activities of the STK32A kinase and the transcription factor EMX2 to regulate the orphan receptor GPR156.
