Scalable fabrication of bijel films via continuous flow slit-coating [PDF]

open access: yesarXiv, 2023
Nanocomposite membranes are an emerging filtration material in the production of clean water. Recently, the fabrication of porous nanocomposite membranes via solvent transfer induced phase separation (STrIPS) was introduced. During STrIPS, the phase separation of two immiscible liquids is arrested by the attachment of nanoparticles at the liquid-liquid

Studying evolution of the primary body axis in vivo and in vitro [PDF]

open access: yesarXiv, 2020
The metazoan body plan is established during early embryogenesis via collective cell rearrangements and evolutionarily conserved gene networks, as part of a process commonly referred to as gastrulation. While substantial progress has been achieved in terms of characterizing the embryonic development of several model organisms, underlying principles of ...

Counterion density profiles at charged flexible membranes [PDF]

open access: yes, 2004
Counterion distributions at charged soft membranes are studied using perturbative analytical and simulation methods in both weak coupling (mean-field or Poisson-Boltzmann) and strong coupling limits. The softer the membrane, the more smeared out the counterion density profile becomes and counterions pentrate through the mean-membrane surface location ...

Wnt Inhibition Safeguards Porcine Embryonic Stem Cells From the Acquisition of Extraembryonic Endoderm Cell Fates

open access: yesAdvanced Science, EarlyView.
The study reports that Wnt inhibitors safeguard porcine embryonic stem cells (ESCs) from acquiring the extraembryonic endoderm (XEN) lineage, and further develop an efficient strategy to derive XEN cells from ESCs. The XEN cells from ESCs exhibit similar transcriptome and chromatin accessibility features to XEN cells from embryos and contribute to ...

Lateral phase separation of confined membranes [PDF]

open access: yes, 2010
We consider membranes interacting via short, intermediate and long stickers. The effects of the intermediate stickers on the lateral phase separation of the membranes are studied via mean-field approximation. The critical potential depth of the stickers increases in the presence of the intermediate sticker.

The flipflop orphan genes are required for limb bud eversion in the Tribolium embryo [PDF]

open access: yes, 2017
Background Unlike Drosophila but similar to other arthropod and vertebrate embryos, the flour beetle Tribolium castaneum develops everted limb buds during embryogenesis.

Development of node architecture and emergence of molecular organizer characteristics in the pig embryo

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The avian node is the equivalent of the amphibian Spemann's organizer, as indicated by its ability to induce a secondary axis, cellular contribution, and gene expression, whereas the node of the mouse, which displays limited inductive capacities, was suggested to be a part of spatially distributed signaling.

Deep sequencing and expression of microRNAs from early honeybee (Apis mellifera) embryos reveals a role in regulating early embryonic patterning

open access: yesBMC Evolutionary Biology, 2012
Background Recent evidence supports the proposal that the observed diversity of animal body plans has been produced through alterations to the complexity of the regulatory genome rather than increases in the protein-coding content of a genome.

Dynamics of membranes driven by actin polymerization [PDF]

open access: yes, 2005
A motile cell, when stimulated, shows a dramatic increase in the activity of its membrane, manifested by the appearance of dynamic membrane structures such as lamellipodia, filopodia and membrane ruffles. The external stimulus turns on membrane bound activators, like Cdc42 and PIP2, which cause increased branching and polymerization of the actin ...

Transport of particles through RO membrane in steady state condition [PDF]

open access: yesarXiv, 2023
Reverse Osmosis(RO) membranes are widespread nowadays for separating the solvent from a solution. RO membranes are made of polymer matrix. Experiments show changes in relative interaction of solvent and solute with RO membrane matrix lead to changes in solvent permeation, solute rejection and fouling.
