Stomatal vs. genome size in angiosperms: the somatic tail wagging the genomic dog?
(Oxford University Press, 2010-04)
Background and Aims Genome size is a function, and the product, of cell volume. As such it is contingent on ecological circumstance. The nature of ‘this ecological circumstance’ is, however, hotly debated. Here, we ...
Seasonal variations of gonadotropins in the pars distalis male viscacha pituitary: Effect of chronic melatonin treatment
(Società Italiana di Istochimica, 2005-12)
The gonadotropes, LH and FSH cells, were immunohistochemically identified in the pituitary pars distalis of the adult male viscacha (Lagostomus maximus maximus) using specific antibodies against hLHb and hFSHb with the ...
Effect of pollution on early diatom colonisation on artificial substrata in urban lowland streams
(Csiro Publishing, 2020-08-26)
The colonisation patterns of diatom assemblages were studied on artificial substrates in lowland streams with different urban pollution levels. Density, diversity, colonisation rates, ecological guilds and cell size classes ...
Label-free counting of Escherichia coli cells in nanoliter droplets using 3D printed microfluidic devices with integrated contactless conductivity detection
(Elsevier Science, 2019-04)
This study describes for the first time the development of 3D printed microfluidic devices with integrated electrodes for label-free counting of E. coli cells incorporated inside droplets based on capacitively coupled ...
Cholesterol depletion activates rapid internalization of submicron-sized acetylcholine receptor domains at the cell membrane
(Taylor & Francis Ltd, 2007-01-09)
Novel effects of cholesterol (Chol) on nicotinic acetylcholine receptor (AChR) cell-surface stability, internalization and function are reported. AChRs are shown to occur in the form of submicron-sized (240–280 nm) domains ...
Human Cytomegalovirus Inhibits Autophagy of Renal Tubular Epithelial Cells and Promotes Cellular Enlargement
(Frontiers Media, 2020-09)
Human Cytomegalovirus (HCMV) is a frequent opportunistic pathogen in immunosuppressed patients, which can be involved in kidney allograft dysfunction and rejection. In order to study the pathophysiology of HCMV renal ...
Freezing resistance in Patagonian woody shrubs: the role of cell wall elasticity and stem vessel size
(Oxford University Press, 2016-03)
Freezing resistance through avoidance or tolerance of extracellular ice nucleation is important for plant survival in habitats with frequent subzero temperatures. However, the role of cell walls in leaf freezing resistance ...
Activated macrophages as a feeder layer for growth of resident cardiac progenitor cells
(Springer, 2014-11)
The adult heart contains a population of cardiac progenitor cells (CPCs). Growing and collecting an adequate number of CPCs demands complex culture media containing growth factors. Since activated macrophages secrete many ...
A dynamic cell recruitment process drives growth of the Drosophila wing by overscaling the vestigial expression pattern
(Academic Press Inc Elsevier Science, 2020-06-15)
Organs mainly attain their size by cell growth and proliferation, but sometimes also grow through recruitment of undifferentiated cells. Here we investigate the participation of cell recruitment in establishing the pattern ...
Electrospun scaffolds with enlarged pore size: Porosimetry analysis
(Elsevier Science, 2018-09)
Electrospun polymeric/composite scaffolds exhibit a micro/nanofibrous structure that resembles the architecture of native extracellular matrix. The unique properties of the interconnected pores and high porosity of electrospun ...
