LPS inmobilization on porous and non-porous supports as an approach for the isolation of anti-LPS host-defense peptides.

Lipopolysaccharides (LPSs) are the major molecular component of the outer membrane of Gram-negative bacteria. This molecule is recognized as a sign of...

Porous and Nonporous Nerve Conduits: The Effects of a Hydrogel Luminal Filler With and Without a Neurite-Promoting Moiety.
Nerve conduits prefilled with hydrogels are frequently explored in an attempt to promote nerve regeneration. This study examines the interplay in vivo between the porosity of the conduit wall and the level of bioactivity of the hydrogel used to fill

Comparison of superficially porous and fully porous silica supports used for a cyclofructan 6 hydrophilic interaction liquid chromatographic stationary phase.
A new HILIC stationary phase comprised of native cyclofructan-6 (CF6) bonded to superficially porous silica particles (2.7μm) was developed. Its performance was evaluated and compared to fully porous silica particles with 5μm (commercially available

Isolation of human mesenchymal stem cells and their cultivation on the porous bone matrix.
Mesenchymal stem cells (MSCs) have a differentiation potential towards osteoblastic lineage when they are stimulated with soluble factors or specific biomaterials. This work presents a novel option for the delivery of MSCs from human amniotic membran

An Experimenting Field Approach for the Numerical Solution of Multiphase Flow in Porous Media.
In this work, we apply the experimenting pressure field technique to the problem of the flow of two or more immiscible phases in porous media. In this technique, a set of predefined pressure fields are introduced to the governing partial differential

An Umpolung Approach for the Chemoselective Arylation of Selenocysteine in Unprotected Peptides.
Herein we report an umpolung strategy for the bioconjugation of selenocysteine in unprotected peptides. This mild and operationally simple approach takes advantage of the electrophilic character of an oxidized selenocysteine (Se-S bond) to react with

Template-free synthesis of beta zeolite membranes on porous α-Al₂O₃ supports.
The preferentially (h0l)-oriented beta zeolite membrane was prepared on the porous α-Al2O3 support by secondary growth of a beta seed layer in the absence of organic templates.

Phylogenomic analysis supports the ancestral presence of LPS-outer membranes in the Firmicutes.
One of the major unanswered questions in evolutionary biology is when and how the transition between diderm (two membranes) and monoderm (one membrane) cell envelopes occurred in Bacteria. The Negativicutes and the Halanaerobiales belong to the class

Planar, Polysilazane-Derived Porous Ceramic Supports for Membrane and Catalysis Applications.
Porous, silicon carbonitride-based ceramic support structures for potential membrane and catalysis applications were generated from a preceramic polysilazane precursor in combination with spherical, ultrahigh-molecular weight polyethylene micropartic

The effects of LPS on the activity of Trp-containing antimicrobial peptides against Gram-negative bacteria and endotoxin neutralization.
A series of synthesized Trp-containing antimicrobial peptides showed significantly different antimicrobial activity against Gram-negative bacteria despite having similar components and amino acid sequences and the same net positive charge and hydroph

Application of immobilized synthetic anti-lipopolysaccharide peptides for the isolation and detection of bacteria.
The molecular detection of microorganisms in liquid samples generally requires their enrichment or isolation. The aim of our study was to evaluate the capture and pre-concentration of bacteria by immobilized particular cationic antimicrobial peptides
