Intracellular Transport of Silver and Gold Nanoparticles and Biological Responses: An Update
International Journal of Molecular Sciences, 2018 Medicine, food, and cosmetics represent the new promising applications for silver (Ag) and gold (Au) nanoparticles (NPs). AgNPs are most commonly used in food and cosmetics; conversely, the main applications of gold NPs (AuNPs) are in the medical field ...

Thermal Migration in Biological Transport?
Biophysical Journal, 1965 It is shown by thermodynamic arguments and by semiquantitative considerations that the contribution of thermal migration to biological transport is likely to be small.

Homogenization of oxygen transport in biological tissues [PDF]
Applicable Analysis, 2015 In this paper, we extend previous work on the mathematical modeling of oxygen transport in biological tissues (Matzavinos et al., 2009). Specifically, we include in the modeling process the arterial and venous microstructure within the tissue by means of homogenization techniques.

Effects of jamming on non-equilibrium transport times in nano-channels
, 2009 Many biological channels perform highly selective transport without direct input of metabolic energy and without transitions from a 'closed' to an 'open' state during transport.

Biological activity in the wake of an island close to a coastal upwelling [PDF]
, 2008 Hydrodynamic forcing plays an important role in shaping the dynamics of marine organisms, in particular of plankton. In this work we study the planktonic biological activity in the wake of an island which is close to an upwelling region.

Random walk with barriers: Diffusion restricted by permeable membranes
, 2010 Restrictions to molecular motion by barriers (membranes) are ubiquitous in biological tissues, porous media and composite materials. A major challenge is to characterize the microstructure of a material or an organism nondestructively using a bulk ...

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population
Population Ecology, EarlyView.This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...
