[Argentine Consensus of the Diagnosis and Treatment of Hereditary Angioedema].

Objectives: Hereditary angioedema (HAE) is a rare disease. During the last years, many studies and advances have been developed with the aim of better understanding the pathophysiology, as well as optimizing patient management. Several international working groups have attempted to clarify and standardize the care of HAE communicated as guidelines and consensus recommendations.

Nonadiabatic electron pumping: maximal current with minimal noise.

The noise properties of pump currents through an open double-quantum-dot setup with nonadiabatic ac driving are investigated. Driving frequencies close to the internal resonances of the double-dot system mark the optimal working points at which the pump current assumes a maximum while its noise power possesses a remarkably low minimum. A rotating-wave approximation provides analytical expressions for the current and its noise power and allows to optimize the noise characteristics.

[Association between soybean dust exposure, allergic sensitivity and profile of respiratory symptoms].

The purpose of this study was to correlate soybean dust (SD) exposure, skin reactivity to soybean hull (SH) allergens, and symptoms of asthma and/or allergic rhinitis. A group of 365 subjects with asthma and/or allergic rhinitis and a control group of 50 individuals without respiratory symptoms were studied. The level of exposure to SD is defined as follows: 1) direct (DE); 2) indirect (ID), and 3) urban (UE).

[Chromatin reorganization in a medium of physiological ionic strength in the presence of additional total histone].

The authors studied the capability of chromatin for structural reorganization in a medium of ionic strength, close to physiological one, under the effect of polyions of polycationic nature--summary histone of chromatin. Electrophoretic analysis demonstrated that like polyanions, summary histone forces out histone HI and partially histones H2B and H2A from chromatin. However, in contrast to polyanions, summary histone makes chromatin resistant to DNase-II, apparently potentiating the aggregation capability of chromatin despite the removal of histone HI.
