Altered whole brain functional connectivity pattern homogeneity in medication-free major depressive disorder.

J Affect Disord 2019 Apr 8;253:18-25. Epub 2019 Apr 8.

Key Laboratory of Adolescent Cyberpsycology and Behavior (CCNU) of Ministry of Education, Central China Normal University, Wuhan 430079, China; School of Psychology, Central China Normal University, Wuhan 430079, China. Electronic address:

Background: Many previous studies have revealed abnormal functional connectivity patterns between brain areas underlying the onset of major depressive disorder (MDD) using resting-state functional magnetic resonance imaging (rs-fMRI). However, how to exactly characterize the voxel-wise whole brain functional connectivity pattern changes in MDD remains unclear, which will provide more convincing evidence for localizing the exactly functional connectivity abnormality in MDD.

Methods: In this study, we employed our newly developed whole brain functional connectivity homogeneity (FcHo) method to identify the voxel-wise changes of functional connectivity patterns in 27 medication-free MDD patients and 34 gender-, age-, and education level-matched healthy controls (HC).

Experience-dependent mechanisms in the regulation of parental care.

Front Neuroendocrinol 2019 Apr 19. Epub 2019 Apr 19.

University of California, Davis, Department of Psychology, One Shields Ave. Davis, CA 95616.

Maternal behavior is a defining characteristic of mammals, which is regulated by a core, conserved neural circuit. However, mothering behavior is not always a default response to infant conspecifics. For example, initial fearful, fragmented or aggressive responses toward infants in laboratory rats and mice can give way to highly motivated and organized caregiving behaviors following appropriate hormone exposure or repeated experience with infants.

Behavioral profile of intermittent vs continuous access to a high fat diet during adolescence.

Behav Brain Res 2019 Apr 19. Epub 2019 Apr 19.

Unidad de Investigación Psicobiología de las Drogodependencias, Departamento de Psicobiología, Facultad de Psicología, Universitat de València, Avda. Blasco Ibáñez, 21, 46010 Valencia, Spain. Electronic address:

Over the past few years, the effects of a high-fat diet (HFD) on cognitive functions have been broadly studied as a model of obesity, although no studies have evaluated whether these effects are maintained after the cessation of this diet. In addition, the behavioral effects of having a limited access to an HFD (binge-eating pattern) are mostly unknown, although they dramatically increase the vulnerability to drug use in contrast to having continuous access. Thus, the aim of the present study was to compare the effects of an intermittent versus a continuous exposure to an HFD during adolescence on cognition and anxiety-like behaviors, as well as to study the changes observed after the interruption of this diet.

A Facial-Action Imposter: How Head Tilt Influences Perceptions of Dominance From a Neutral Face.

Psychol Sci 2019 Apr 22:956797619838762. Epub 2019 Apr 22.

Department of Psychology, The University of British Columbia.

Research on face perception tends to focus on facial morphology and the activation of facial muscles while ignoring any impact of head position. We raise questions about this approach by demonstrating that head movements can dramatically shift the appearance of the face to shape social judgments without engaging facial musculature. In five studies (total N = 1,517), we found that when eye gaze was directed forward, tilting one's head downward (compared with a neutral angle) increased perceptions of dominance, and this effect was due to the illusory appearance of lowered and V-shaped eyebrows caused by a downward head tilt.

Ambivalence in the Early Years of Marriage: Impact on Ambulatory Blood Pressure and Relationship Processes.

Ann Behav Med 2019 Apr 22. Epub 2019 Apr 22.

Mannheim Institute of Public Health, Universität Heidelberg, Heidelberg, Germany.

Background: Marriage is associated with lower cardiovascular morbidity and mortality, but quality matters. Marriages characterized by ambivalent behaviors (containing both highly positive and highly negative behaviors concurrently) may not confer the same cardiovascular benefits as characterized by purely positive behavior. Ambivalence is assumed to take time to develop but couples in the early years of marriage may already exhibit ambivalent behaviors and thus be at increased risk for future cardiovascular events.

Pupylated proteins are subject to broad proteasomal degradation specificity and differential depupylation.

PLoS One 2019 22;14(4):e0215439. Epub 2019 Apr 22.

Institute of Molecular Biology and Biophysics, Department of Biology, ETHZ, Zurich, Switzerland.

In actinobacteria, post-translational modification of proteins with prokaryotic ubiquitin-like protein Pup targets them for degradation by a bacterial proteasome assembly consisting of the 20S core particle (CP) and the mycobacterial proteasomal ATPase (Mpa). Modification of hundreds of cellular proteins with Pup at specific surface lysines is carried out by a single Pup-ligase (PafA, proteasome accessory factor A). Pupylated substrates are recruited to the degradative pathway by binding of Pup to the N-terminal coiled-coil domains of Mpa. Read More

Temporal pattern separation in hippocampal neurons through multiplexed neural codes.

PLoS Comput Biol 2019 Apr 22;15(4):e1006932. Epub 2019 Apr 22.

Department of Neuroscience, University of Wisconsin-Madison, WI, United States of America.

Pattern separation is a central concept in current theories of episodic memory: this computation is thought to support our ability to avoid confusion between similar memories by transforming similar cortical input patterns of neural activity into dissimilar output patterns before their long-term storage in the hippocampus. Because there are many ways one can define patterns of neuronal activity and the similarity between them, pattern separation could in theory be achieved through multiple coding strategies. Using our recently developed assay that evaluates pattern separation in isolated tissue by controlling and recording the input and output spike trains of single hippocampal neurons, we explored neural codes through which pattern separation is performed by systematic testing of different similarity metrics and various time resolutions.

Finding the balance between model complexity and performance: Using ventral striatal oscillations to classify feeding behavior in rats.

PLoS Comput Biol 2019 Apr 22;15(4):e1006838. Epub 2019 Apr 22.

Department of Psychiatry, Geisel School of Medicine at Dartmouth, Dartmouth College, Hanover, New Hampshire, United States of America.

The ventral striatum (VS) is a central node within a distributed network that controls appetitive behavior, and neuromodulation of the VS has demonstrated therapeutic potential for appetitive disorders. Local field potential (LFP) oscillations recorded from deep brain stimulation (DBS) electrodes within the VS are a pragmatic source of neural systems-level information about appetitive behavior that could be used in responsive neuromodulation systems. Here, we recorded LFPs from the bilateral nucleus accumbens core and shell (subregions of the VS) during limited access to palatable food across varying conditions of hunger and food palatability in male rats.

Siponimod (BAF312) Treatment Reduces Brain Infiltration but Not Lesion Volume in Middle-Aged Mice in Experimental Stroke.

Stroke 2019 May;50(5):1224-1231

From the Department of Neurology (A.V., J.R., A.D., J.S.), University Medicine, Greifswald, Germany.

Background and Purpose- The contribution of neuroinflammation and, in particular, the infiltration of the brain by lymphocytes is increasingly recognized as a substantial pathophysiological mechanism after stroke. The interaction of lymphocytes with endothelial cells and platelets, termed thromboinflammation, fosters microvascular dysfunction and secondary infarct growth. Siponimod is an S1PR (sphingosine-1-phosphate receptor) modulator, which blocks the egress of lymphocytes from lymphoid organs and has demonstrated beneficial effects in multiple sclerosis treatment.

Pharmacological Treatment of Youth Substance Use Disorders.

J Child Adolesc Psychopharmacol 2019 Apr 22. Epub 2019 Apr 22.

Department of Psychiatry and Behavioral Sciences, Medical University of South Carolina, Charleston, South Carolina.

While the majority of youth who experiment with alcohol and drugs do not develop problematic levels of use, 5% of adolescents and 15% of young adults meet criteria for a substance use disorder (SUD). Pharmacotherapy, in combination with behavioral interventions, has the potential to increase the likelihood of successful treatment for youth struggling with SUD; however, the literature in this area is limited. To date, there are no Food and Drug Administration (FDA)-approved medications for adolescent SUD, other than buprenorphine, which has been approved down to 16 years of age for opioid use disorder.

Understanding Water Structure in an Ion-Pair Solvation Shell in the Vicinity of a Water/Membrane Interface.

J Phys Chem B 2019 Apr 22. Epub 2019 Apr 22.

The anomalous properties of interfacial water at the surface of a lipid membrane and their implications on nearby chemical processes are well recognized. However, we have found that ion pairing thermodynamics may not be significantly affected by interfacial water in a classical, non-polarizable force field. To trace the root cause of such a counter-intuitive finding, we performed atomistic molecular dynamics simulations to explore the impact of polarizable interactions and characterize the hydration structure of a sodium chloride (NaCl) ion pair at the surface of a model lipid membrane and in a bulk phase.

Water Contaminant Levels Interact with Parenting Environment to Predict Development of Depressive Symptoms in Adolescents.

Dev Sci 2019 Apr 22:e12838. Epub 2019 Apr 22.

Ian H. Gotlib, Department of Psychology, Stanford University, 450 Serra Mall, Stanford, CA, 94305.

Contaminants in drinking water, such as lead, nitrate, and arsenic, have been linked to negative physical health outcomes. We know less, however, about whether such pollutants also predict mental health problems and, if so, the conditions under which such effects are strongest. In this longitudinal study, we examined whether drinking water contaminants interact with negative family environments (parental psychological control) to predict changes in depressive symptoms in 110 adolescents-a developmental period when symptoms often first emerge.

Sexual cues influence cocaine-induced locomotion, anxiety and the immunoreactivity of estrogen receptor alpha and tyrosine hydroxylase in both sexes.

J Neuroendocrinol 2019 Apr 22:e12720. Epub 2019 Apr 22.

College of Biological Sciences and Engineering, North Minzu University, Yinchuan, Ningxia, 750021, China.

Dyadic physical social interaction influences cocaine-seeking behavior, but whether limited sexual cues (LSCs) from an opposite-sex partner influence behavioral responses to cocaine is unclear. We investigated this issue using a cylindrical wire cage containing a stimulus mouse (of the opposite sex); the subject mouse had access to this stimulus mouse during a "binge" injection pattern (injected with cocaine or saline vehicle twice a day, at 6-h intervals). Following the second injection, locomotion and anxiety-like behaviors were examined using the open-field and elevated plus-maze test, while estrogen receptor alpha (ERα) and tyrosine hydroxylase (TH) immunoreactivity were also examined.

Behavioral Tracking and Neuromast Imaging of Mexican Cavefish.

J Vis Exp 2019 Apr 6(146). Epub 2019 Apr 6.

Department of Biology, University of Hawai'i at Mānoa;

Cave-dwelling animals have evolved a series of morphological and behavioral traits to adapt to their perpetually dark and food-sparse environments. Among these traits, foraging behavior is one of the useful windows into functional advantages of behavioral trait evolution. Presented herein are updated methods for analyzing vibration attraction behavior (VAB: an adaptive foraging behavior) and imaging of associated mechanosensors of cave-adapted tetra, Astyanax mexicanus.

Mediating effect of social support on the associations between health literacy, productive aging, and self-rated health among elderly Chinese adults in a newly urbanized community.

Medicine (Baltimore) 2019 Apr;98(16):e15162

No. 4 West China Teaching Hospital, Sichuan University, Chengdu, China.

With the growing urbanization of China, which has changed older adults' living conditions, lifestyle, and the source of support, coupled with rapid population aging, the health status of the elderly should be paid attention to. In addition to objective indicators such as the decline of function, specific factors, such as social support, health literacy, and productive aging, also have an impact on the health outcomes of the elderly. However, the interrelationships among these factors and their potential mechanisms in the context of urbanization remain unclear. Read More
