Fibrin association at hybrid biointerfaces made of clot-binding peptides and polythiophene [PDF]

open access: yes, 2016
The properties as biointerfaces of electroactive conducting polymer-peptide biocomposites formed by poly(3,4-ethylenedioxythiophene) (PEDOT) and CREKA or CR(NMe)EKA peptide sequences (where Glu has been replaced by N-methyl-Glu in the latter) have been ...

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

In vitro evaluation of bi-layer silk fibroin scaffolds for gastrointestinal tissue engineering

open access: yesJournal of Tissue Engineering, 2014
Silk fibroin scaffolds were investigated for their ability to support attachment, proliferation, and differentiation of human gastrointestinal epithelial and smooth muscle cell lines in order to ascertain their potential for tissue engineering.

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

open access: yesAdvanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Association between genotypic diversity and biofilm production in group B Streptococcus [PDF]

open access: yes, 2016
Background: Group B Streptococcus (GBS) is a leading cause of sepsis and meningitis and an important factor in premature and stillbirths. Biofilm production has been suggested to be important for GBS pathogenesis alongside many other elements ...

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

open access: yesAdvanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

An Electron Microscopic Observation on Epithelial Attachment

open access: yesNihon Shishubyo Gakkai Kaishi (Journal of the Japanese Society of Periodontology), 1973
臨床的に正常歯肉と判定し, 光顕で病理組織的に初期歯肉炎とみとめた成人 (20歳~54歳) の辺縁歯肉を, 電子顕微鏡的に観察した。観察は上皮付着部を歯冠側から根尖側の尖端部にわたって行い, その結果次の様な所見を得た。(1) 歯肉溝中央より歯冠側のエナメル質表面には, cuticle に接して上皮細胞がわずかに存在した。cuticle と上皮細胞との間は, 電子密度の低い一層で隔てられ, 両者にはしばしば hemi-desmosome による接合をみとめた。(2) セメント質部の cuticle は, 根尖側にゆくにしたがってその厚さを減じ, 付着上皮の根尖側最尖端の上皮細胞とセメント質との接触部には cuticle をみとめなかった。(3) セメント質表面の cuticle は ...

Alterations in vasodilator-stimulated phosphoprotein (VASP) phosphorylation: associations with asthmatic phenotype, airway inflammation and β\u3csub\u3e2\u3c/sub\u3e-agonist use [PDF]

open access: yes, 2006
Background Vasodilator-stimulated phosphoprotein (VASP) mediates focal adhesion, actin filament binding and polymerization in a variety of cells, thereby inhibiting cell movement.
