Mindfulness meditation modulates reward prediction errors in a passive conditioning task
(Frontiers, 2015-02-12)Reinforcement learning models have demonstrated that phasic activity of dopamine neurons during reward expectation encodes information about the predictability of reward and cues that predict reward. Self-control strategies ... -
Minor defects of the luminal integrity in arterial introducer eSheaths after transcatheter aortic valve implantation
(PLOS, 2017-05-08)Background Medical devices such as implant delivery systems are commonly used during minimally invasive procedures in the cardiovascular system. These devices often have lubricious polymer coatings to reduce friction ... -
Mismatch Responses in the Awake Rat: Evidence from Epidural Recordings of Auditory Cortical Fields
(PLOS, 2013-04-30)Detecting sudden environmental changes is crucial for the survival of humans and animals. In the human auditory system the mismatch negativity (MMN), a component of auditory evoked potentials (AEPs), reflects the violation ... -
The Mitochondrial Basis of Aging and Age-Related Disorders
(MDPI, 2017-12-19)Aging is a natural phenomenon characterized by progressive decline in tissue and organ function leading to increased risk of disease and mortality. Among diverse factors that contribute to human aging, the mitochondrial ... -
Modulation of CREB in the Dorsal Lateral Geniculate Nucleus of Dark-Reared Mice
(Hindawi, 2012)The cAMP-response element-binding protein (CREB) plays an important role in visual cortical plasticity that follows the disruption of sensory activity, as induced by dark rearing (DR). Recent findings indicate that the ... -
Modulation of gap junction-associated Cx43 in neural stem/progenitor cells following traumatic brain injury
(2017-09)Restoration of learning and memory deficits following traumatic brain injury (TBI) is attributed, in part, to enhanced neural stem/progenitor cell (NSPCs) function. Recent findings suggest gap junction (GJ)-associated ... -
Molecular Analysis of BRCA1 in Human Breast Cancer Cells Under Oxidative Stress
(Nature Publishing Group, 2017-03-06)The precise manner in which physical changes to the breast cancer susceptibility protein (BRCA1) affect its role in DNA repair events remain unclear. Indeed, cancer cells harboring mutations in BRCA1 suffer from genomic ... -
Molecular mechanisms of experience-dependent plasticity in visual cortex
(Royal Society, 2008)A remarkable amount of our current knowledge of mechanisms underlying experience-dependent plasticity during cortical development comes from study of the mammalian visual cortex. Recent advances in high-resolution cellular ... -
Molecular structure and dimeric organization of the Notch extracellular domain as revealed by electron microscopy.
(2010-05-07)BACKGROUND: The Notch receptor links cell fate decisions of one cell to that of the immediate cellular neighbor. In humans, malfunction of Notch signaling results in diseases and congenital disorders. Structural information ... -
Molecular Surveillance of Viral Processes Using Silicon Nitride Membranes
(MDPI, 2013-03)Here we present new applications for silicon nitride (SiN) membranes to evaluate biological processes. We determined that 50-nanometer thin films of SiN produced from silicon wafers were sufficiently durable to bind active ... -
A Molecular Toolkit to Visualize Native Protein Assemblies in the Context of Human Disease
(Springer Nature, 2015-09-23)We present a new molecular toolkit to investigate protein assemblies natively formed in the context of human disease. The system employs tunable microchips that can be decorated with switchable adaptor molecules to select ... -
Monetary Favors and Their Influence on Neural Responses and Revealed Preference
(Society for Neuroscience, 2010-07-14)Favors from a sender to a receiver are known to bias decisions made by the recipient, especially when the decision relates to the sender, a feature of social exchange known as reciprocity. Using an art-viewing paradigm ... -
Monte Carlo Planning Method Estimates Planning Horizons during Interactive Social Exchange
(PLOS, 2015-06)Reciprocating interactions represent a central feature of all human exchanges. They have been the target of various recent experiments, with healthy participants and psychiatric populations engaging as dyads in multi-round ... -
𝛼-Motor neurons are spared from aging while their synaptic inputs degenerate in monkeys and mice
(Wiley, 2017)Motor function deteriorates with advancing age, increasing the risk of adverse health outcomes. While it is well established that skeletal muscles and neuromuscular junctions (NMJs) degenerate with increasing age, the ... -
MRSA USA300 at Alaska native medical center, Anchorage, Alaska, USA, 2000-2006
(Centers for Disease Control and Prevention, 2012-01)To determine whether methicillin-resistant Staphylococcus aureus (MRSA) USA300 commonly caused infections among Alaska Natives, we examined clinical MRSA isolates from the Alaska Native Medical Center, Anchorage, during ... -
Mucosal Airway Laceration Secondary To Endobronchial Ultrasonography
(Hindawi, 2012-01-01)Endobronchial ultrasound-guided transbronchial needle aspiration is becoming the standard of care for mediastinal sampling to diagnose and stage lung cancer. It is considered to be safe and rivals the gold standard, ... -
Multilevel analysis of BMI growth trajectories of US school children: Features and risk factors
(Elsevier, 2019-07-17)Childhood obesity continues to be a major focus of public health efforts in the United States, where nearly 17% of children are obese. In this study, we focused on two significant features that characterize U.S. society—school ... -
Multiple Retinal Axons Converge onto Relay Cells in the Adult Mouse Thalamus
(Cell, 2015)Activity-dependent refinement of neural circuits is a fundamental principle of neural development. This process has been well studied at retinogeniculate synapses—synapses that form between retinal ganglion cells (RGCs) ... -
Myocarditis Secondary to Mesalamine-Induced Cardiotoxicity in a Patient with Ulcerative Colitis
(Hindawi, 2018-03-15)Development of cardiac manifestations in patients diagnosed with inflammatory bowel disease undergoing treatment with mesalamine is a rare. When this occurs, it can be difficult to tease out the primary etiology, as both ... -
Necessary, Yet Dissociable Contributions of the Insular and Ventromedial Prefrontal Cortices to Norm Adaptation: Computational and Lesion Evidence in Humans
(Society for Neuroscience, 2015-01-14)Social norms and their enforcement are fundamental to human societies. The ability to detect deviations from norms and to adapt to norms in a changing environment is therefore important to individuals’ normal social ...
