RESUMO
The measurement of two-particle angular correlation functions in high-multiplicity e^{+}e^{-} collisions at sqrt[s]=10.52 GeV is reported. In this study, the 89.5 fb^{-1} of hadronic e^{+}e^{-} annihilation data collected by the Belle detector at KEKB are used. Two-particle angular correlation functions are measured in the full relative azimuthal angle (ΔÏ) and three units of pseudorapidity (Δη), defined by either the electron beam axis or the event-shape thrust axis, and are studied as a function of charged-particle multiplicity. The measurement in the thrust axis analysis, with mostly outgoing quark pairs determining the reference axis, is sensitive to the region of additional soft gluon emissions. No significant anisotropic collective behavior is observed with either coordinate analyses. Near-side jet correlations appear to be absent in the thrust axis analysis. The measurements are compared to predictions from various event generators and are expected to provide new constraints to the phenomenological models in the low-energy regime.
RESUMO
Cardiac amyloidosis is accumulation in the heart of a pathologic fibrillar protein amyloid. It represents a heterogeneous group of states from clinically insignificant amyloid accumulation in isolated atrial amyloidosis to severe involvement of the heart in primary amyloidosis when mean duration of life equals to 6 months. Insufficient awareness of physicians of this pathology leads to erroneous and belated diagnosis of cardiac amyloidosis. This paper contains contemporary data of pathophysiology, clinical manifestation, diagnosis, treatment, and prognosis of various variants of cardiac amyloidosis.

The paper gives current general data on the structure of amyloid fibril and the principles in the classification of amyloidosis, information on the clinical course of cardiac and renal involvements in systemic AL and AA amyloidosis, and that on diagnostic and prognostic criteria and the specific features of cardiorenal links. The authors draw the conclusion that the identification of acute and chronic cardiorenal links is of practical value for systemic amyloidosis. Cardiorenal and renocardiac syndromes are not always differentiated clearly in the systemacy of involvement.
