The role of biofilms in subsurface transport processes [PDF]
, 2010 Landfill and radioactive waste disposal risk assessments focus on contaminant transport and are principally concerned with understanding the movement of gas, water and solutes through engineered barriers and natural groundwater systems.

Mechanisms of nuclear pore complex assembly – two different ways of building one molecular machine
FEBS Letters, 2017 The nuclear pore complex (NPC) mediates all macromolecular transport across the nuclear envelope. In higher eukaryotes that have an open mitosis, NPCs assemble at two points in the cell cycle: during nuclear assembly in late mitosis and during nuclear ...

Nuclear pore interactions with the genome [PDF]
Current Opinion in Genetics & Development, 2014 Within the nucleus, chromatin is functionally organized into distinct nuclear compartments. The nuclear periphery, containing Nuclear Pore Complexes (NPCs), plays an important role in the spatial organization of chromatin and in transcriptional regulation.

Preparation of nuclear matrices from cultured cells: subfractionation of nuclei in situ [PDF]
, 1984 Analyses of the different structural systems of the nucleus and the proteins associated with them pose many problems. Because these systems are largely overlapping, in situ localization studies that preserve the in vivo location of proteins and cellular ...

Postmitotic nuclear pore assembly proceeds by radial dilation of small membrane openings
Nature Structural & Molecular Biology, 2017 The nuclear envelope has to be reformed after mitosis to create viable daughter cells with closed nuclei. How membrane sealing of DNA and assembly of nuclear pore complexes (NPCs) are achieved and coordinated is poorly understood.

Multi-scale simulation of capillary pores and gel pores in Portland cement paste [PDF]
, 2015 The microstructures of Portland cement paste (water to cement ratio is 0.4, curing time is from 1 day to 28 days) are simulated based on the numerical cement hydration model, HUMOSTRUC3D (van Breugel, 1991; Koenders, 1997; Ye, 2003).

Interactome Mapping Reveals the Evolutionary History of the Nuclear Pore Complex
PLoS Biology, 2016 The nuclear pore complex (NPC) is responsible for nucleocytoplasmic transport and constitutes a hub for control of gene expression. The components of NPCs from several eukaryotic lineages have been determined, but only the yeast and vertebrate NPCs have ...

Molecular genetics of oogenesis in Drosophila melanogaster [PDF]
Invertebrate Survival Journal, 2004 Gonadal development requires complex differentiation programs leading to the production offunctional female and male gametes. Upon fertilization, while the male germ cell contributes to thenewly formed zygote only its genetic material, the female germ ...

Meiotic cellular rejuvenation is coupled to nuclear remodeling in budding yeast. [PDF]
, 2019 Production of healthy gametes in meiosis relies on the quality control and proper distribution of both nuclear and cytoplasmic contents. Meiotic differentiation naturally eliminates age-induced cellular damage by an unknown mechanism.
