ATP Uptake in the Golgi and Extracellular Release Require Mcd4 Protein and the Vacuolar H + -ATPase
(American Society for Biochemistry and Molecular Biology, 2003)Extracellular nucleotides signal via a large group of purinergic receptors. Although much is known about these receptors, the mechanism of nucleotide transport out of the cytoplasm is unknown. We developed a functional ... -
ATR inhibition selectively sensitizes G1 checkpoint-deficient cells to lethal premature chromatin condensation
(National Academy of Sciences, 2001) -
ATR Is Not Required for p53 Activation but Synergizes with p53 in the Replication Checkpoint
(American Society for Biochemistry and Molecular Biology, 2002)ATR (ataxia telangiectasia and Rad-3-related) is a protein kinase required for survival after DNA damage. A critical role for ATR has been hypothesized to be the regulation of p53 and other cell cycle checkpoints. ATR has ... -
Attachment Patterns Trigger Differential Neural Signature of Emotional Processing in Adolescents
(Public Library of Science, 2013)Background: Research suggests that individuals with different attachment patterns process social information differently, especially in terms of facial emotion recognition. However, few studies have explored social information ... -
Attention Alters Perceived Attractiveness
(SAGE Publications, 2016-03-10)Can attention alter the impression of a face? Previous studies showed that attention modulates the appearance of lower-level visual features. For instance, attention can make a simple stimulus appear to have higher contrast ... -
Attention bias modification for social anxiety: A systematic review and meta-analysis
(Elsevier BV, 2015)Research on attention bias modification (ABM) for social anxiety disorder (SAD) is inconclusive, with some studies finding clear positive effects and other studies finding no significant benefit relative to control training ... -
Attention Bias Modification Training Via Smartphone to Reduce Social Anxiety: A Randomized, Controlled Multi-Session Experiment
(Springer Science + Business Media, 2014)Testing feasibility and efficacy of psychological treatment via mobile devices is important, given its potential benefits for high-dosage treatment delivery, widespread and inexpensive dissemination, and efficient research ... -
Attention selection, distractor suppression and N2pc
(Elsevier BV, 2009)N2pc is generally interpreted as the electrocortical correlate of the distractor-suppression mechanisms through which attention selection takes place in humans. Here, we present data that challenge this common N2pc ... -
Attention Training Toward and Away from Threat in Social Phobia: Effects on Subjective, Behavioral, and Physiological Measures of Anxiety
(Elsevier, 2012)Social Phobics exhibit an attentional bias for threat in probe detection and probe discrimination paradigms. Attention training programs, whereby probes always replace nonthreat cues, reduce attentional bias for threat ... -
Attention, Intentions, and the Structure of Discourse
(Association for Computational Linguistics/MIT, 1986)In this paper we explore a new theory of discourse structure that stresses the role of purpose and processing in discourse. In this theory, discourse structure is composed of three separate but interrelated components: the ... -
Attentional bias modification in depression through gaze contingencies and regulatory control using a new eye-tracking intervention paradigm: study protocol for a placebo-controlled trial
(BioMed Central, 2016)Background: Attentional biases, namely difficulties both to disengage attention from negative information and to maintain it on positive information, play an important role in the onset and maintenance of the disorder. ... -
Attentional bias toward suicide-related stimuli predicts suicidal behavior.
(American Psychological Association (APA), 2010)A long-standing challenge for scientific and clinical work on suicidal behavior is that people often are motivated to deny or conceal suicidal thoughts. We proposed that people considering suicide would possess an objectively ... -
Attentional control mediates the relationship between social anhedonia and social impairment
(Frontiers Media S.A., 2014)Social anhedonia (SA), a trait-like disinterest in social contact and diminished capacity to experience pleasure from social interactions, is consistently associated with social impairments in both healthy and clinical ... -
Attenuated Spreading in Sanskrit Retroflex Harmony
(MIT Press - Journals, 2017)Drawing on a two-million-word corpus of Sanskrit, two previously unrecognized generalizations are documented and analyzed concerning the morpho-prosodic conditioning of retroflex spreading (nati). Both reveal harmony to ... -
Attenuation of age-related changes in mouse neuromuscular synapses by caloric restriction and exercise
(Proceedings of the National Academy of Sciences, 2010)The cellular basis of age-related behavioral decline remains obscure but alterations in synapses are likely candidates. Accordingly, the beneficial effects on neural function of caloric restriction and exercise, which are ... -
Attenuation of Notch and Hedgehog Signaling Is Required for Fate Specification in the Spinal Cord
(Public Library of Science, 2012)During the development of the spinal cord, proliferative neural progenitors differentiate into postmitotic neurons with distinct fates. How cells switch from progenitor states to differentiated fates is poorly understood. ... -
Attitude and Self-reported Practice Regarding Prognostication in a National Sample of Internists
(American Medical Association (AMA), 1998)Background Since prognostication appears increasingly important in clinical practice, especially in end-of-life care, we examined physicians' experiences and attitudes regarding it. Methods We mailed a survey to a ... -
Attractive Noncovalent Interactions in Asymmetric Catalysis: Links Between Enzymes and Small Molecule Catalysts
(Proceedings of the National Academy of Sciences, 2010)Catalysis by neutral, organic, small molecules capable of binding and activating substrates solely via noncovalent interactions—particularly H-bonding—has emerged as an important approach in organocatalysis. The mechanisms ... -
Attractive photons in a quantum nonlinear medium
(Springer Nature, 2013)The fundamental properties of light derive from its constituent particles—massless quanta (photons) that do not interact with one another\(^1\). However, it has long been known that the realization of coherent interactions ... -
Attractors at Weak Gravity
(Elsevier, 1998)We study the attractor mechanism in low energy effective D=4, N=2 Yang-Mills theory weakly coupled to gravity, obtained from the effective action of type IIB string theory compactified on a Calabi-Yau manifold. Using special ...
