N = 1 dualities of SO and USp gauge theories and T-duality of string theory
(Elsevier, 1997)Extending recent work on SU gauge theory, we engineer local string models for N = 1 four-dimensional SO and USp gauge theories coupled to matter in the fundamental. The local models are type IIB orientifolds with D7 branes ... -
N = 4 topological strings
(Elsevier, 1995)We show how to make a topological string theory starting from an N = 4 superconformal theory. The critical dimension for this theory is c ($) over cap = 2 (c = 6). It is shown that superstrings (in both the RNS and GS ... -
N-Acetyl-Serotonin Protects HepG2 Cells from Oxidative Stress Injury Induced by Hydrogen Peroxide
(Hindawi Publishing Corporation, 2014)Oxidative stress plays an important role in the pathogenesis of liver diseases. N-Acetyl-serotonin (NAS) has been reported to protect against oxidative damage, though the mechanisms by which NAS protects hepatocytes from ... -
N-Alpha-Acetylation of α-Synuclein Increases Its Helical Folding Propensity, GM1 Binding Specificity and Resistance to Aggregation
(Public Library of Science, 2014)A switch in the conformational properties of α-synuclein (αS) is hypothesized to be a key step in the pathogenic mechanism of Parkinson’s disease (PD). Whereas the beta-sheet-rich state of αS has long been associated with ... -
N-cadherin prevents the premature differentiation of anterior heart field progenitors in the pharyngeal mesodermal microenvironment
(Nature Publishing Group, 2014)The cardiac progenitor cells (CPCs) in the anterior heart field (AHF) are located in the pharyngeal mesoderm (PM), where they expand, migrate and eventually differentiate into major cell types found in the heart, including ... -
N-Glycan Moieties in Neonatal Fc Receptor Determine Steady-state Membrane Distribution and Directional Transport of IgG

N-linked glycosylation of SV2 is required for binding and uptake of botulinum neurotoxin A
(2016)Botulinum neurotoxin serotype A1 (BoNT/A1) is one of the most dangerous potential bioterrorism agents, and exerts its action by invading motoneurons. It is also a licensed drug widely used for medical and cosmetic applications. ... -

N-Methyl D-Aspartate (NMDA) Receptor Antagonists and Memantine Treatment for Alzheimer’s Disease, Vascular Dementia and Parkinson’s Disease
(Bentham Science Publishers Ltd., 2012-07)Memantine, a partial antagonist of N-methyl-D-aspartate receptor (NMDAR), approved for moderate to severe Alzheimer’s disease (AD) treatment within the US and Europe under brand name Namenda (Forest), Axura and Akatinol ... -
An N-nitrosating metalloenzyme constructs the pharmacophore of streptozotocin
(Springer Science and Business Media LLC, 2019-02)N-nitroso-containing small molecules, such as the bacterial natural product streptozotocin, are prominent carcinogens as well as important cancer chemotherapeutics. Despite this functional group’s significant impact on ... -
N-terminal Extension of the Cholera Toxin A1-chain Causes Rapid Degradation after Retrotranslocation from Endoplasmic Reticulum to Cytosol
(American Society for Biochemistry and Molecular Biology, 2010)Cholera toxin travels from the plasma membrane to the endoplasmic reticulum of host cells, where a portion of the toxin, the A1-chain, is unfolded and targeted to a protein-conducting channel for retrotranslocation to the ... -
N-WASP Is Essential for the Negative Regulation of B Cell Receptor Signaling
(Public Library of Science, 2013)Negative regulation of receptor signaling is essential for controlling cell activation and differentiation. In B-lymphocytes, the down-regulation of B-cell antigen receptor (BCR) signaling is critical for suppressing the ... -
N-WASP Is Required for Structural Integrity of the Blood-Testis Barrier
(Public Library of Science, 2014)During spermatogenesis, the blood-testis barrier (BTB) segregates the adluminal (apical) and basal compartments in the seminiferous epithelium, thereby creating a privileged adluminal environment that allows post-meiotic ... -
N100 Repetition Suppression Indexes Neuroplastic Defects in Clinical High Risk and Psychotic Youth
(Hindawi Publishing Corporation, 2016)Highly penetrant mutations leading to schizophrenia are enriched for genes coding for N-methyl-D-aspartate receptor signaling complex (NMDAR-SC), implicating plasticity defects in the disease's pathogenesis. The importance ... -
N2 Universal: A Case Study of an NDA
(1994)Food and drug law, like all areas of administrative law, is rife with tension among countervailing principles. The Food and Drug Administration is charged with protecting the health and safety of the American public. This ... -
Na,K-ATPase alpha isoforms at the blood-cerebrospinal fluid-trigeminal nerve and blood-retina interfaces in the rat
(BioMed Central, 2013)Background: Cerebrospinal fluid (CSF) sodium concentration increases during migraine attacks, and both CSF and vitreous humor sodium increase in the rat migraine model. The Na,K-ATPase is a probable source of these sodium ... -
Nabokov's Details: Making Sense of Irrational Standards
(2012-12-20)Vladimir Nabokov's passion for detail is well-known, central to our very idea of the "Nabokovian." Yet Nabokov's most important claims for detail pose a challenge for the reader who would take them seriously. Startlingly ... -

Nacre Tablet Thickness Records Formation Temperature in Modern and Fossil Shells
(Elsevier BV, 2017-02-15)Nacre, the iridescent outer lining of pearls and inner lining of many mollusk shells, is composed of periodic, parallel, organic sheets alternating with aragonite (CaCO3) tablet layers. Nacre tablet thickness (TT) generates ...
