Twenty-six chemical elements and oxidative status were determined in serum of 12 patients with first demyelinating episode and brain magnetic resonance imaging compatible with the disease at different time points. Quantifications of Al, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Hg, Li, Mg, Mn, Mo, Ni, Pb, Sb, Si, Sn, Sr, V, Tl, W, Zn and Zr, as well as of serum oxidative status and antioxidant capaci...

The most cpmmon parameters in the specific protein field, namely the immunoglobulins G, A and M were investigated on the recently developed Immuno Video Nephelometer System (IVNS). This System consists of the nephelometer, a microprocessor controlled program and a monitor screen, where instructions, Standard curve and results are displayed. Scattered light of immuno-complexes is measured at equ...

We connect the recent medical and economic literatures on the long-run effects of early-life conditions by analyzing the effects of economic conditions on the individual cardiovascular (CV) mortality rate later in life, using individual data records from the Danish Twin Registry covering births since the 1870s and including the cause of death. To capture exogenous variation of conditions early ...

We describe a rapid, relatively simple-procedure for fluorometry of glutamine in cerebrospinal fluid. Glutamine is de-aminated with diluted sulfuric acid at 100 degrees C. The ammonia liberated is then reacted with a buffered o-phthalaldehyde--mercaptoethanol solution, pH 7.4, to form a fluorochrome. Fluorescence is linearly related to the concentration of glutamine from 0.10 to 0.60 g/L (0.68 ...

This paper describes compensation methods for deformations of both the parallel kinematic mechanism and the frame supporting the mechanism. In general, these deformations are caused by the heat, the internal forces and the external forces during the processes. First, runouts and deformations of spherical joints and revolutionary joints are measured and compensated by nine displacement sensors b...

In this paper, a hybrid control strategy is studied and implemented on an Inductive Power Transfer (IPT) system to simultaneously realize zero-voltage switching (ZVS) constant current (CC) voltage (CV) battery charging. A steady-state analysis of pulse frequency modulation was conducted, based the characteristic gain versus frequency, CC CV charging modes were promised. The ZVS inverter obtaine...

A number of studies are now collecting diffusion tensor imaging (DTI) data across sites. While the reliability of anatomical images has been established by a number of groups, the reliability of DTI data has not been studied as extensively. In this study, five healthy controls were recruited and imaged at eight imaging centers. Repeated measures were obtained across two imaging protocols allowi...

The means by which various microevolutionary processes have acted in the past to produce patterns of cranial variation that characterize modern humans is not thoroughly understood. Applying a microevolutionary framework, within- and among-population variance/covariance (V/CV) structure was compared for several functional and developmental modules of the skull across a worldwide sample of modern...

wk). Birds grew 819 g during the 4 to 8wk period (CV = 15.0 %), as compared to only 389 g in the 8 to 12 wk period (CV = 15.3 %). Although there was no difference in the variation on a population basis, drastic changes are apparent when data was expressed in relative gains. The variation for relative gains ranged from a low of 17.2 % in the 4 to 8 wk period to a high of 41.0 % in the 16 to 18 w...

Intra-specific morphological variation in the indigenous catfish Arius jella (Ariidae) was studied in five estuarine localities in Sri Lanka (Koggala lagoon, Walawe estuary, Garanduwa lagoon, Nilwala estuary and Chilaw lagoon) using morphometric analysis. Five morphometric characteristics describing the shape of the fish were significantly different among some of the locations. Significantly sh...
