The value of simultaneous 62-lead electrocardiographic recordings in localizing the site of origin of ectopic ventricular activation in a structurally normal heart was assessed by examining body surface QRS integral maps in 12 patients during left and right ventricular (LV and RV) pacing at 182 distinct endocardial sites. A data base of38 characteristic mean integral maps was composed after vis...

If laboratory monitoring of low molecular weight heparin (LMWH) therapy is required the test of choice is the anti Xa activity assay. The relationship between anti Xa results obtained using different techniques is unknown. The aim of the present study was to compare anti Xa results obtained with eight different commercially available anti Xa activity assays (five chromogenic and three clotting ...

The choice of a reference image typically influences the results of deformable image registration, thereby making it asymmetric. This is a consequence of a spatially non-uniform weighting in the cost function integral that leads to general registration inaccuracy. The inhomogeneous integral measure--which is the local volume change in the transformation, thus varying through the course of the r...

The emergence of new technologies for the production structural elements gives impetus to development their design, in particular with involvement a topology optimization method. most common algorithm designing topologically optimal structures is focused on reducing elastic flexibility at given volume material. However, closer engineering design approach minimization element while limiting resu...

To prepare anti-Brucella abortus serum used for calibrate the agglutination test follwing the national standard, 4 anti-Brucella abortus sera were obtained from 4 cows infected with Brucella abortus naturally. By potency testing, the third serum was selected. Sterility, vaccum degree, residual moisture, uniformity and stability of this standard material were tested and proved to meet the nation...

The purpose of this paper is to prove, assuming that the conjecture of Lang and Vojta holds true, that there is a uniform bound on the number of stably integral points in the complement of the theta divisor on a principally polarized abelian surface defined over a number field. Most of our argument works in arbitrary dimension and the restriction on the dimension ≤ 2 is used only at the last st...

CONTEXT Whether ergocalciferol (D(2)) and cholecalciferol (D(3)) are equally effective to increase and maintain serum 25-hydroxyvitamin D [25(OH)D] concentration is controversial. OBJECTIVE The aim of the study was to evaluate the effect of daily and once monthly dosing of D(2) or D(3) on circulating 25(OH)D and serum and urinary calcium. DESIGN, SETTING AND PARTICIPANTS In a university cli...
