Fungal pores feel the pull S teinberg et al. report that fungi use motor proteins to distribute their nuclear pores around the nuclear envelope. In animal cells, the nuclear lamina holds the nuclear pores in place, ensuring that they are evenly spaced. The lamina prevents nuclear pores from clustering, promoting import of cargoes through the pores and helping to organize the chromosomes, which ...

The mechanism of the formation of alveolar pores (Kohn's pores) in neonatal male rabbits was studied by scanning electron microscopy and scanning electron microscopic morphometric analysis. The number of alveolar pores per alveolus was increased after birth. About 80 percent f alveolar pores had Type H alveolar epithelial cells on their edges when the rabbits were I-day old. This percentage dec...

Mesoporous silicon has become a material of high interest for drug delivery due to its outstanding internal surface area and inherent biodegradability. We have previously reported the preparation of mesoporous silicon microparticles (MS-MPs) synthesized by an advantageous electrochemical method, and showed that due to their inner structure they can adsorb proteins in amounts exceeding the mass ...

Within multiscale brain dynamics, the structure-function relationship between cellular changes at a lower scale and coordinated oscillations at a higher scale is not well understood. This relationship may be particularly relevant for understanding functional impairments after a mild traumatic brain injury (mTBI) when current neuroimaging methods do not reveal morphological changes to the brain ...

Biodegradable anisotropic neat porous starch materials without any additional cross-linking, plasticizer or extra matter have been fabricated via facile ice-templating method. Waxy maize was dissolved in water followed by unidirectional freezing and ice sublimation. The influence of process parameters (starch concentration retrogradation time) on the morphology, density, mechanical properties u...
