Mean Transit Time and Mean Residence Time for Linear Diffusion–Convection–Reaction Transport System [PDF]

Computational and Mathematical Methods in Medicine, 2007
Characteristic times for transport processes in biological systems may be evaluated as mean transit times (MTTs) (for transit states) or mean residence times (MRT) (for steady states). It is shown in a general framework of a (linear) reaction–diffusion–convection equation that these two times are related.

Flow and mean residence time in karst unsaturated zone (Ochoz Cave, Moravian Karst) [PDF]

, 2012
Flow and mean residence time in epikarst and unsaturated zone was studied above the Ochoz cave in the Moravian Karst. I studied various flow components with different residence time in unsaturated zone and the influence of soil and epikarst on seepage ...

Catchment travel time distributions and water flow in soils [PDF]

, 2011
Many details about the flow of water in soils in a hillslope are unknowable given current technologies. One way of learning about the bulk effects of water velocity distributions on hillslopes is through the use of tracers.

Suppression of lung adenocarcinoma migration through organelle alkalization by human lactoferrin – albumin fusion

FEBS Open Bio, EarlyView.
This paper reveals how human lactoferrin–albumin fusion (hLF‐HSA) potently suppresses lung adenocarcinoma cell migration. hLF‐HSA upregulates NHE7, leading to Golgi alkalization, disruption of the Golgi secretome, downregulation of MMP1, and reversal of EMT. These findings suggest a novel Golgi‐targeting strategy to suppress cancer cell migration.

Rural-urban differences in the association between individual, facility, and clinical characteristics and travel time for cancer treatment

BMC Public Health, 2020
Background Greater travel time to cancer care has been identified as a potential barrier to care as well as associated with worse health outcomes. While rural cancer patients have been shown to travel farther for care, it is not known what patient ...

A physiological view and structures of mean residence times

General physiology and biophysics, 2014
The author's previous theoretical study described the determination of a physiologically realistic structure of a mean residence time of an intravenously administered drug (Ďurišová 2012). This study continues previous work and the aim is to determine physiologically realistic structures of mean residence times of a drug administered either orally ...

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

FEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Enhancement of stability of metastable states in the presence of Lévy noise

SciPost Physics
The barrier-crossing event for superdiffusion characterized by symmetric Lévy flights is analyzed. Starting from the fractional Fokker-Planck equation, we derive an integro-differential equation along with the necessary conditions to calculate the mean ...
