Abstract:

Abstract We reported the rapid and permanent deletion of immunization-induced bovine CD4 T cell responses to Anaplasma marginale major surface proteins (MSPs) after infection. To determine if antigen-specific T cells were anergic, sequestered, or deleted, CD4 T cells specific for a MSP1a T cell epitope were enumerated with a DRB3*1101 tetramer. The pre-challenge frequency of tetramer+ CD4+ cells of 0.025% dropped rapidly at the peak of infection to control levels of 0.0003%, paralleling loss of antigen specific T cell responses. Background frequencies of tetramer+ CD4+ T cells in spleen and ly

Background:Social support is defined as a helpful resource that can meet an individual’s urgent needs and is provided by a network of others, such as family members, friends, colleagues and other communities. Perceived social support (PSS) is the subjective support that individuals may experience, emphasizing the individual’s self-understanding, experience and feelings of social support from different sources. Social support directly exerts beneficial effects on the health-related quality of life in rheumatoid arthritis and fibromyalgia patients.Objectives:The aim of this study is to compare t

ABSTRACT Anaplasma marginale, a tick-borne rickettsial pathogen of cattle, infects bovine erythrocytes, resulting in mild to severe hemolytic disease that causes economic losses in domestic livestock worldwide.

Development of A. marginale in cell culture was morphologically similar to that described previously in ticks.

ABSTRACT Anaplasma marginale, the causative agent of bovine anaplasmosis, is a tick-borne rickettsial pathogen of cattle that multiplies in erythrocytes and tick cells. Major surface protein 1a (MSP1a) and MSP1b form the MSP1 complex of A. marginale, which is involved in adhesion of the pathogen to host cells. In this study we tested the hypothesis that MSP1a and MSP1b were glycosylated, because the observed molecular weights of both proteins were greater than the deduced molecular masses. We further hypothesized that the glycosylation of MSP1a plays a role in adhesion of A. marginale to tick

Abstract. The Multidimensional Scale of Perceived Social Support (MSPSS) is a widely used 12-item measure that assesses perceived social support from three sources: friends, family, and significant others.

The current studies sought to develop such a reduced scale across two studies.

Abstract:

Background and Purpose: Low social support is associated with worse outcomes in patients with heart failure. Thus, the purpose of this study was to examine the reliability and validity of the Multidimensional Scale of Perceived Social Support (MSPSS). Methods: We performed a secondary analysis of registry data from patients (n = 475) with confirmed heart failure. Results: The MSPSS demonstrated excellent internal consistency reliability. Factor analysis yielded 3 factors that explained 83% of the variance in perceived social support. More than half of the sample had depressive symptoms (56%).

Methods: In total 462 participants were recruited - 310 medical students from Chiang Mai University and 152 psychiatric patients, and they completed the Thai version of the MSPSS, the State Trait Anxiety Inventory (STAI), the Rosenberg Self-Esteem Scale (RSES) and the Thai Depression Inventory (TDI). Test-retest reliability was conducted over a four week period. Results: Factor analysis produced three-factor solutions for both patient (PG) and student groups (

Abstract:

To improve the accuracy and efficiency of fault data identification of traffic detectors is crucial in order to decrease the probability of unexpected failures of the intelligent transportation system (ITS). Since convolutional fault data recognition based on traffic flow three-parameter law has a poor capability for multiscale of fault data, PCA (principal component analysis) is adopted for traffic fault data identification. This paper proposes the fault data detection models based on the PCA model, MSPCA (multiscale principal component analysis) model and improved MSPCA model, respectively.

Abstract:

In this paper, a new methodology to develop an Optimal Fuzzy model (OptiFel) using an improved Multi-swarm Particle Swarm Optimization (MsPSO) algorithm is proposed with a new adaptive inertia weight based on Grey relational analysis. Since the classical MsPSO suffers from premature convergence and can be trapped into local optima, which significantly affects the model accuracy, a modified MsPSO algorithm is presented here. The most important advantage of the proposed algorithm is the adjustment of fewer parameters in which the main parameter is the inertia weight. In fact, the control of this

Abstract:

Metabolic syndrome is the pathological basis of cardiovascular and cerebrovascular diseases and type 2 diabetes. With the prevalence of modern lifestyles, the incidence of metabolic syndrome has risen rapidly. In recent years, marine sulfate polysaccharides (MSPs) have shown positive effects in the prevention and treatment of metabolic syndrome, and they mainly come from seaweeds and marine animals. MSPs are rich in sulfate and have stronger biological activity compared with terrestrial polysaccharides. MSPs can alleviate metabolic syndrome by regulating glucose metabolism and lipid metabolism

This paper deals with bistatic track association and deghosting in the classical frequency modulation (FM)-based multi-static primary surveillance radar (MSPSR). The main contribution of this paper is a novel algorithm for bistatic track association and deghosting. The proposed algorithm is based on a hierarchical model which uses the Indian buffet process (IBP) as the prior probability distribution for the association matrix. The inference of the association matrix is then performed using the classical reversible jump Markov chain Monte Carlo (RJMCMC) algorithm with the usage of a custom set

Abstract:

Network intrusion detection systems that employ existing IP traceback (IPTBK) algorithms are generally unable to trace multiple attack sources. In these systems, the sampling mechanism only screens parts of the routing information, which leads to the tracing of the neighbour of the attack source and fails to identify the attack source. Theoretically, the multimodal optimisation problem cannot be solved for all of its multiple solutions using the traditional particle swarm optimisation (PSO) algorithm. The present study focuses on the use of multiple-swarm PSO (MSPSO) for recursively tracing at

ABSTRACT We present a comprehensive census of X-ray millisecond pulsars (MSPs) in 29 Galactic globular clusters (GCs), including 68 MSPs with confirmed X-ray luminosities and 107 MSPs with X-ray upper limits. We compile previous X-ray studies of GC MSPs, and add new analyses of six MSPs (PSRs J1326–4728A, J1326–4728B, J1518+0204C, J1717+4308A, J1737–0314A, and J1807–2459A) discovered in five GCs. Their X-ray spectra are well described by a single blackbody model, a single power-law model, or a combination of them, with X-ray luminosities ranging from 1.9 × 1030to 8.3 × 1031 erg s−1.

Abstract. The charging by secondary electron emission (SEE) from particles is known as a significant charging process in astrophysical plasmas. This work aims at evaluating the significance of SEE for charging of meteoric smoke particles (MSPs) in the Earth's polar atmosphere. Here, the atmosphere is subject to a bombardment of energetic electrons from the magnetosphere (and partly the sun). We employ the SEE formalism to MSPs in the upper mesosphere using electron precipitation fluxes for three different precipitation strengths. In addition, we address the possible effect of tertiary electron

Abstract. We investigate if the presence of meteoric smoke particles (MSPs) influences the electron temperature during artificial heating in the D-region. By transferring the energy of powerful high-frequency radio waves into thermal energy of electrons, artificial heating increases the electron temperature. Artificial heating depends on the height variation of electron density. The presence of MSPs can influence the electron density through charging of MSPs by electrons, which can reduce the number of free electrons and even result in height regions with strongly reduced electron density, so-
