Diffusion of virus from the gels decreased dramatically, especially at high concentrations of FXIII, even for fibrin gels with low fibrinogen concentration that were loaded with high titer virus.
We compared HIV-1+ T cell uptake with cell-free virus using supernatant derived from the same HIV-1+ T cells immediately prior to coculture with MDMs or across 3 μm transwells that prevent T cell transfer but allow free diffusion of virus (Martin et al., 2010).
Moreover, the rapid diffusion of influenza virus throughout Peru, even in the more remote regions, also serves as a potent reminder of how quickly influenza virus can disseminate.
Rumor propagation is very similar to the diffusion of a virus, thus, most of the existing models of rumor propagation are derived from the models of infectious diseases [3 11].
We investigated the dynamics of porcine reproductive and respiratory syndrome virus (PRRSV) variability in a range of swine PRRS-positive farms located in Northern Italy, to provide insights into the epidemiology and diffusion of the virus, particularly throughout the entire swine production chain.
Intranuclear diffusion of CPV virus like particles (VLPs) was studied with photoactivable VP2.
A further analysis (shown in Text S1) has revealed that, if the risk of infection is overestimated during the early phases of the epidemic, the diffusion of the virus would be slowed down (thus gaining time for vaccine production).
An additional consideration is that the increase in vitreous viscosity in humans above the age of 40 could impair the diffusion of the virus in older patients' vitreous, though this concern is potentially offset by an increase in liquid vitreous localized directly in front of the retina [24] enabling one to inject into this fluid region and avoid the more viscous vitreous gel.
Hence, it is possible that frequent human movement in and out of this location is creating more diffusion of influenza virus.
If the 1918 pandemic virus had indeed reached Chile by July 1918, only ≈4 months after the earliest putative outbreaks in New York City (4 ), this finding would indicate rapid transcontinental diffusion of the virus via boats and railways, reminiscent of the 1889 pandemic (38 ).
Based on the observation that the diffusion coefficients of virus-sized dextrans are ∼25% smaller in the nucleus than in water [52], the nuclear diffusion coefficient of the CPV VLP can be estimated to be D = 4.3 µm2/s.
