Dendritic cells (DC) present antigen and initiate T cell-mediated immune responses. To investigate the possible association of autoimmunity with DC function, we compared the accessory activity of splenic DC from Wistar/Furth (WF) and diabetes-prone (DP) BioBreeding (BB) rats. The latter develop autoimmune diabetes and thyroiditis. DC function was quantified in vitro by measuring T cell prolifer...

OBJECTIVES The purpose of this study was to evaluate the ability of novel Doppler indices of left ventricular (LV) systolic and diastolic function to predict survival in patients with congestive heart failure (CHF). BACKGROUND Congestive heart failure is associated with an increased risk of death or cardiac transplantation, yet techniques to predict survival are limited. METHODS Doppler-der...

the biobreeding- diabetes prone (bb-dp) rat spontaneously develops an autoimmune diabetic syndrome that is dependent on the rt1 u major histocompatibility complex (mhc) haplotype and homozygosity for an allele at the lymphopenia (lyp) locus. lyp mutation is responsible for a peripheral t -lymphopenia. there are other genetic loci contributing to diabetes susceptibility in this strain. bb rats c...

Abstract To improve the efficiency of dim point target detection based on dynamic programming (DP), this paper proposes a multi-frame method DP ring network (DPRN). In proposed method, first, trajectory is approximated using piecewise linear function. The velocity space partition (VSP-DP) used to accumulate merit functions each segment avoid function diffusion in different spaces. addition, mat...

BACKGROUND The complete continuous-wave Doppler mitral regurgitant velocity curve should allow reconstruction of the ventriculoatrial (VA) pressure gradient from mitral valve closure to opening, including left ventricular (LV) isovolumic contraction, ejection, and isovolumic relaxation. Assuming that the left atrial pressure fluctuation is relatively minor in comparison with the corresponding L...

in this paper, after reviewing the classification of quantifiers, we aim toanswer the question of whether the merge position of quantifiers kheili and ba’zi is in the dp. contra moazzami (2006) and samiian (1983), we show that these quantifiers do not originate  in the dp. by appealing to the preference of merge over move and in the light of giusti (1991), we propose that these elements merge a...
