systemic reaction characterized by fever, leukocytosis, increase in erythrocyte sedimentation rate, increases in Leucocytosis secretion of ACTH and glucocorticoids, activation of Complement activat complement and clotting cascades, decreases in serum levels of iron and zinc, a negative nitrogen balance, and by dramatic changes in the concentration of some plasma ,l' proteins. These proteins are...

Phase response curve (PRC) of an oscillatory neuron describes the response of the neuron to external perturbation. The PRC is useful to predict synchronized dynamics of neurons; hence, its measurement from experimental data attracts increasing interest in neural science. This paper introduces a Bayesian method for estimating PRCs from data, which allows for the correlation of errors in explanat...

In a recent paper, Suppes, de Barros, & Oas (2012) used neural oscillators to create a model, based on reasonable neurophysiological assumptions, of the behavioral stimulus-response (SR) theory. In this paper, we describe the main characteristics of the model, emphasizing its physical and intuitive aspects.

The patterns of acute-phase response (APR) biomarkers differ upon various inflammatory conditions. Little information is available on the systemic inflammatory response in urticaria/angio-oedema. It has been shown that concentrations of circulating APR biomarkers, IL-6 and C-reactive protein (CRP), are elevated more in severe chronic urticaria (CU) than in patients showing milder urticarial sym...

OBJECTIVE The purpose of this study was to examine the interactive action of serum amyloid A (SAA), group IIA secretory phospholipase A(2) (sPLA(2)-IIA), and cholesteryl ester transfer protein (CETP) on HDL remodeling and cholesterol efflux during the acute phase (AP) response elicited in humans after cardiac surgery. METHODS AND RESULTS Plasma was collected from patients before (pre-AP), 24 ...

Background: In recent years, neoadjuvant chemoradiation and subsequent surgical resection with total mesorectal excision has been shown to increase local control with decreased toxicity. Neoadjuvant chemoradiotherapy is the standard treatment for locally advanced rectal cancer. In this study we evaluated the efficacy a cox-2 inhibitor on pathologic response, sphincter preservation and acute tox...

Acute phase proteins (APPs) are important diagnostic indicators of inflammatory disturbances in animals. The objectives of the current study were to validate analytical methods for measuring haptoglobin (Hp), serum amyloid A (SAA), acid soluble glycoprotein (ASG), fibrinogen, and albumin concentrations in goats and to evaluate their response to an inflammatory stimulus in this species. Intra- a...

Using 'classical' experimental protocols, a human phase-response curve (PRC) to a single 3-h bright light pulse has been established. When the light pulse was centred slightly before the time of body temperature minimum, the circadian system delayed, whilst a pulse slightly after the minimum advanced it. Maximum phase shifts were about 2 h. When light pulses over 3 successive cycles were used, ...

Many real oscillators are coupled to other oscillators, and the coupling can affect the response of the oscillators to stimuli. We investigate phase-response curves (PRCs) of coupled oscillators. The PRCs for two weakly coupled phase-locked oscillators are analytically obtained in terms of the PRC for uncoupled oscillators and the coupling function of the system. Through simulation and analytic...

OBJECTIVE To test the hypothesis that not all acute phase reactants respond in the same way during attacks of familial Mediterranean fever (FMF) and that there is a subclinical acute phase response (APR) in a proportion of patients during the interval between attacks. METHODS Blood and urine samples were obtained from 49 patients with FMF during an attack and the attack-free period that follo...
