Neurosteroids: endogenous analgesics?
… target for many clinical drugs, and certain endogenous neurosteroids act as potent allosteric modulators of these receptors. A developmental change in the rate of exponential decay of GABAergic synaptic events has been observed in other types of neurones and this may be related in part to …

Novel Endogenous Antimicrobial Peptides
… derived from heparin-binding sequences within endogenous proteins. In addition, novel antimicrobial activity and heparin-binding capacity were discovered for the anaphylatoxin C3a, generated during activation of the complement system, and the inactive derivative of C3a (C3adesArg), as well as …

Mus dunni endogenous virus (MDEV)
… and therefore named the novel virus Mus dunni endogenous virus (MDEV). Retroviral interference experiments indicate that MDEV uses a different receptor for cell entry than those used by previously-known mouse retroviruses. The MDEV receptor is widely expressed, as judged by the ability of MDEV …

Optimal taxation with endogenous wages
… of three chapters on optimal tax theory with endogenous wages. Chapter 1 studies optimal linear and nonlinear income taxation when firms do not know workers' abilities, and competitively screen them through nonlinear compensation contracts, unobservable to the government, in a …

Relative Wages and Endogenous Growth
… an important role in growth. Recent models of endogenous growth based on technological progress predict that high technological progress and growth are associated with a high relative supply of skilled workers who earn constant or relatively low wages. Chapter 1 of this dissertation reviews …

Essays on Matching With Endogenous Effort
… two-sided matching literature by including an endogenous effort choice after the matching stage. We examine how different matching rules affect incentives to exert effort and the costs paid to induce various effort levels in three settings: a legal system, an education system, and a labor …

Bifurcation Analysis of Endogenous Growth Models
… parameter space, the dynamics of the Uzawa-Lucas endogenous growth model. We examine the stability properties of both centralized and decentralized versions of the model and locate Hopf and transcritical bifurcation boundaries. In an extended analysis, we investigate the existence of Andronov-Hopf …

Knowledge Codification and Endogenous Growth Theory
The present thesis develops a formal model of endogenous growth that incorporates costly knowledge codification as a means of intergenerational knowledge transfer. It identifies the circumstances under which knowledge codification takes place in the long run and studies its effects on long run …

Targeting and Manipulating Endogenous Transcriptional Condensates
… optogenetic tools to target and manipulate endogenous transcriptional condensates. We find that intrinsically disordered regions of transcription factors can be used to direct cargo to the condensates. Combined with an improved light-induced dimer and its binding partner allow us to generate …

Regulation of Endogenous Excitatory Neurotransmitters by Isoprostanes
… in vitro. However, the regulation of retinal endogenous glutamateby IsoPs is unknown. The objective of the present study was to investigate the effect of 8-isoprostaglandin E2 (8-isoPGE2) on endogenous levels of glutamate and its metabolite, glutamine in bovine retina, ex vivo. Freshly …

An endogenous search model and its applications
… decision of the displaced workers is made endogenous. The introduction of participation data enables us to identify more parameters and to avoid potential selection bias in the empirical work. The model is applied to study how the presence of young children affects the reservation wage and …

Endogenous atrial natriuretic factor and airway control
… two experiments investigating the role of endogenous atrial natriuretic factor (ANF) in the modulation of airway calibre and bronchial hyperresponsiveness in humans under normal physiological conditions. Two approaches are used. One approach examines the diurnal variation of endogenous ANF …

Endogenous Shocks in the New Keynesian Model
… has recently devoted considerable attention to endogenous shocks to the Phillips curve. One reason for such scrutiny is their ability to generate a meaningful tradeoff between inflation and the output gap without resorting to ad hoc exogenous shocks. Chapter 1 surveys three mechanisms that give …

Sampling, Detection, and Characterization of Endogenous Peptides
"In the past two decades mass spectrometric detection has exploded onto the scene of biological research due to the soft ionization techniques of matrix assisted laser desorption ionization (MALDI) and electro spray ionization (ESI), as evidenced by the 2002 Nobel Prize in Chemistry. Using these …

Deoxyribose oxidation chemistry and endogenous DNA adducts
Endogenous and exogenous oxidants react with cellular macromolecules to generate a variety of electrophiles that react with DNA produce cytotoxic and mutagenic adducts. One source of such electrophiles is deoxyribose in DNA itself. Oxidation of each position in deoxyribose generates a unique …

Endogenous and chemical modifications of model proteins
… biopharmaceuticals. To probe the biochemistry of endogenous glycosylation and to test the efficacy of novel synthetic modifications, tractable protein scaffolds are needed. Previously, members of the pancreatic-type ribonuclease (ptRNases) superfamily have been utilized as model protein scaffolds. …

Training endogenous task shifting using neurologic music therapy
… neurologic music therapy approach to train endogenous task shifting would create positive results in standard measures of executive functioning (the Trail Making Test and the PASAT). In this pilot study, participants were randomly assigned to one of three groups: a neurologic music therapy …
