Subjective value, not a gridlike code, describes neural activity in ventromedial prefrontal cortex during value-based decision-making.

Neuroimage 2021 May 12:118159. Epub 2021 May 12.

Department of Psychology, University of Pennsylvania, Philadelphia, PA, 19104 USA.

Across many studies, ventromedial prefrontal cortex (vmPFC) activity has been found to correlate with subjective value during value-based decision-making. Recently, however, vmPFC has also been shown to reflect a hexagonal gridlike code during navigation through physical and conceptual space, and such gridlike codes have been proposed to enable value-based choices between novel options. Here, we first show that, in theory, a hexagonal gridlike code can in some cases mimic vmPFC activity previously attributed to subjective value, raising the possibility that the subjective value correlates previously observed in vmPFC may have actually been a misconstrued gridlike signal.

Nurr1 deficiency shortens free running period, enhances photoentrainment to phase advance, and disrupts circadian cycling of the dopamine neuron phenotype.

Behav Brain Res 2021 May 12:113347. Epub 2021 May 12.

East Carolina University, Department of Anatomy and Cell Biology, Brody School of Medicine, Greenville, NC, USA. Electronic address:

Neurological and neuropsychiatric disorders, including addiction, schizophrenia, and Parkinson's disease (PD), involve dysfunction in midbrain dopamine (DA) neurotransmission with severity of disease symptoms and progression associated with disrupted circadian rhythms. The nuclear transcription factor Nurr1, essential for DA neuron (DAN) development, survival, and maintenance, is also known to interact with circadian rhythm regulating clock proteins. In the Nurr1-null heterozygous (+/-) mice, a Nurr1 deficient model which reproduces some of the alterations in DA function found in schizophrenia and PD, we measured, using wheel-running activity, the free running period (tau) and photoperiod entrainment.

Antisense oligonucleotide-mediated knockdown of Mpzl3 attenuates the negative metabolic effects of diet-induced obesity in mice.

Physiol Rep 2021 May;9(9):e14853

Department of Anesthesiology & Perioperative Medicine, Penn State University College of Medicine, Hershey, PA, USA.

Previously, we demonstrated that global knockout (KO) of the gene encoding myelin protein zero-like 3 (Mpzl3) results in reduced body weight and adiposity, increased energy expenditure, and reduced hepatic lipid synthesis in mice. These mice also exhibit cyclic and progressive alopecia which may contribute to the observed hypermetabolic phenotype. The goal of the current study was to determine if acute and peripherally restricted knockdown of Mpzl3 could ameliorate the negative metabolic effects of exposure to a high-fat and sucrose, energy-dense (HED) diet similar to what was observed in global Mpzl3 KO mice in the absence of a skin phenotype.

J Eur Acad Dermatol Venereol 2021 May 15. Epub 2021 May 15.

Pfizer Inc, New York, NY, USA.

Given the lack of head-to-head studies of systemic therapies in moderate-to-severe atopic dermatitis (AD), network meta-analyses (NMAs) can provide comparative efficacy and safety data to inform clinical decision making. In this NMA, eligible randomized controlled trials (RCTs) published before October 24, 2019 were identified by a systematic literature review. Short-term (12-16 weeks) efficacy (Investigator's Global Assessment [IGA] and Eczema Area and Severity Index [EASI] responses), patient-reported outcomes (PROs), and safety data from each trial were abstracted and analyzed separately for monotherapy and combination-therapy (systemic plus topical anti-inflammatory therapy).
