The ventilator-induced cyclic changes in intrathoracic pressure produce significant arterial pressure variations if the circulation is fluid responsive.
There may be regional and annual variations in the circulation of different coronavirus species, as have been described by others [ 19].
Jiang et al. (2013b) considered several possibilities such as (i) the accuracy of SSN, (ii) sunspot tilt angle variation, and (iii) the variation in the meridional circulation during cycle 23.
Our study was designed to examine the extent of genetic variation and the circulation pattern of hMPV in a single South African community in 3 consecutive years (2000 2002) by sequence analysis of the 2 surface (F and G) glycoprotein genes from South African strains.
An exemplary dataset from September 2013 is discussed in which a variation in the efficiency of shallow circulation and convection, the processes that transport volatile-rich magma to the surface of the summit lava lake, appears to have caused two distinctly different phases of lake activity and degassing.
The interannual variation in Southern Ocean circulation patterns causes variability in biogeochemical cycles [ Lovenduski and Gruber, 2005; Lenton and Matear, 2007; Lovenduski et al., 2007].
In addition, the contrast variations of corin level in the circulation and tissues indicated that corin may have other unknown functions or that there are some other unknown factors that could influence corin levels.
As a result, the cost and time could be saved and the variation of therapeutic protein levels in the circulation could be avoided.
To reduce the variability among different subjects, which was probably due to the potential variation in the amounts of contrast entering the circulation, the volume-related parameters were standardized by dividing the corresponding parameters detected in the ipsilateral kidney and were presented as ratios.
In short, despite annual variations registered, the circulation of the four DENV serotypes from temperate to subtropical Argentina is currently a main public health concern.
