The bead model and limit behaviors of dimer models
, 2011 In this paper, we study the bead model: beads are threaded on a set of wires on the plane represented by parallel straight lines. We add the constraint that between two consecutive beads on a wire; there must be exactly one bead on each neighboring wire.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Microbial Cell Factories, 2018 Background Bacterial expression and purification of recombinant proteins under homogeneous active form is often challenging. Fusion to highly soluble carrier proteins such as Maltose Binding Protein (MBP) often improves their folding and solubility, but ...

Method to Determine the Optimal Aptamer-to-Bead Ratio by Using Flow Cytometry
Scientifica, 2023 Research on the effective attachment of aptamers to beads, which is essential for using aptamers, has made relatively little progress. Here, we demonstrate a new method based on flow cytometry to determine the optimal aptamer-to-bead ratio for aptamer ...

SCORBUTIC BEADING OF THE RIBS [PDF]
Archives of Pediatrics and Adolescent Medicine, 1920 Early study on infantile scurvy: "Beading of the ribs, the so-called rachitic rosary, should not be regarded as pathognomonic of rickets. It occurs very frequently in connection with infantile scurvy and is one of the typical signs of this disorder, developing in the course of the disease, and disappearing rapidly with the recession of the other ...

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Book Review: The Bead Maker From Ribe: The Story of a Viking Craftsman by Thomas Risom
EXARC Journal, 2021 Having been involved with experimental work with Viking Era beads for a decade and a half, I am always looking for more information on the topic. Ribe is the most significant beadmaking site of the Viking Era due to its archaeological remains and the ...

Defence Technology, 2018 The weld quality is significantly affected by the weld parameters (arc voltage, welding current, nozzle to plate distance and welding speed) in the submerged arc welding (SAW). Bead-on-plate welds were performed on stainless steel plates by automated SAW

Electrical conductance of a 2D packing of metallic beads under thermal perturbation [PDF]
, 2000 Electrical conductivity measurements on a 2D packing of metallic beads have been performed to study internal rearrangements in weakly pertubed granular materials. Small thermal perturbations lead to large non gaussian conductance fluctuations.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
