Herein, we applied the Illumina MiSeq pyrosequencing platform to amplify V3–V4 hypervariable regions of 16 S rRNA gene gut microbiota (GM) and a gas chromatograph–mass spectrometer detect metabolites after supplementation with pumpkin oligosaccharides (POSs) determine metabolic markers mechanisms in rats type 2 diabetes (T2D). The POSs alleviated glucolipid metabolism by decreasing serum low-de...
A new hybrid thermoplastic polyurethane (TPU) system that incorporates an organic, biodegradable poly(D, L-lactide) soft block with a hard block bearing the inorganic polyhedral oligosilsesquioxane (POSS) moiety is introduced and studied. Changes in the polyol composition made through variation of the hydrophilic initiator molecular weight show direct control of the final transition temperature...
The process of insertion of molecular oxygen and nitrogen into polyhedral oligomeric silsesquioxanes (POSS) has been investigated theoretically. Using ab initio methods, the N2interaction with the POSS has been described with restricted Hartree−Fock (RHF) with a triple-ζ basis set, while systems involving O2 require restricted open shell (ROHF) wave functions, to account for their open-shell gr...
This paper considers the problem of transforming a resource feasible, fixed-times schedule into a partial order schedule (POS) to enhance its robustness and stability properties. Whereas a fixed-times schedule is brittle in the face of unpredictable execution dynamics and can quickly become invalidated, a POS retains temporal flexibility whenever problem constraints allow it and can often absor...
In this work, a novel soft shape memory polymer nanocomposite derived from a bacterial medium-chain-length polyhydroxyalkanoate, poly(3-hydroxyoctanoate-co-3-hydroxyundecenoate) (PHOU), used to form a covalent network grafted with polyhedral oligomeric silsesquioxane (POSS), a crystallizable inorganic–organic hybrid nanofiller, was prepared. The PHOU– POSS nanocomposite, PHOU–POSSw-net [w (1⁄4 ...
A new approach is presented for detecting whether a particular computation of an asynchronous distributed system satis es Poss (read \possibly "), meaning the system could have passed through a global state satisfying predicate , or Def (read \de nitely "), meaning the system de nitely passed through a global state satisfying . Detection can be done easily by straightforward state-space search;...
Incorporation of additives into a reinforced concrete matrix to delay or even completely avoid the initiation corrosion during service-life construction is widely pursued topic. One new promising technologies achieving increased interest incorporate inhibitors encapsulated in layered double hydroxide (LDH). LDH structures follow controlled release inhibitor while chloride efficiently trapped at...
An acid-base switchable dendritic complex was constructed by self-assembly between dibenzo-24-crown-8 terminated T(10)-POSS dendrimer and dibenzylammonium hexafluorophosphate salt based on T(8)-POSS. The formation and its threading-dethreading property were characterized by (1)H NMR and UV-visible absorption spectroscopy.
In situ endothelialization of cardiovascular implants has emerged in recent years as an attractive means of targeting the persistent problems of thrombosis and intimal hyperplasia. This study aimed to investigate the efficacy of immobilizing anti-CD34 antibodies onto a POSS-PCU nanocomposite polymer surface to sequester endothelial progenitor cells (EPCs) from human blood, and to characterize t...
With the continuous and expanding use of implantable biomaterials in a clinical setting, this study aims to elucidate the influence of sterilization techniques on the material surface and bulk properties of two polyurethane nanocomposite biomaterials. Both solid samples and porous membranes of nondegradable polyhedral oligomeric silsesquioxane poly(carbonate-urea) urethane (POSS-PCU) and a biod...
