Objective: Delirium is a common and potentially life-threatening clinical syndrome. The authors investigated resting-state functional connectivity in patients with delirium to elucidate possible neural mechanisms underlying this disorder. Method: Twenty-two underwent initial MRI at rest during an episode of delirium. Of these patients, 14 completed follow-up scans after the resolved. comparison subjects without also scanning. assessed cortical using seed region posterior cingulate cortex...
As the researches to utilize nanotechnology in food science are advanced, applications of various fields industry have increased. Nanotechnology can be applied for production, processing, storage, and quality control foods. Nanomaterials, unlike conventional microscale materials, having novel characteristics improve sensory foods by imparting texture, color, appearance. has been used design nanosensors detection harmful components a smart packaging system enabling recognize contamination...
An in situ cross-linkable gelatin–poly(ethylene glycol)–tyramine (GPT) hydrogel was developed as a novel injectable material for tissue regenerative medicine. The formed rapidly using horseradish peroxidase (HRP) and hydrogen peroxide (H2O2). gelation times could be controlled from five seconds to over one minute by changing the HRP concentration, mechanical properties varying H2O2 concentration. storage moduli of hydrogels ranged approximately 200 8000 Pa. In addition, an vitrocell...
Fast in situ forming supramolecular hydrogels consisted of the tyramine-conjugated structures and chitosan derivative were prepared via an enzymatic reaction with horseradish peroxidase (HRP) hydrogen peroxide (H2O2). The gel formation was varied within a time period 5 s to 10 min by controlling concentrations HRP, H2O2, polymers. Tyramine conjugation at different sites structure resulted significant changes physical properties degradation that confirmed water uptake, compressive strength...
The prevalence and characteristics of low-temperature-tolerant Bacillus cereus (psychrotolerant B. cereus) in green leaf lettuce collected during cold chain were investigated. Among the 101 isolated samples, only 18 capable growth at 7 °C, these isolates shared potential health hazard with mesophilic isolates. Most psychrotolerant contained various combinations nheA, nheB, nheC,hblA, hblA, hblC, hblD, cytK, entFM. possessed least two enterotoxin genes 28% harbored tested nine genes....
Chemical antibacterials are widely used to control microbial growth but have raised concerns about health risks. It is necessary find alternative, non-toxic antibacterial agents for the inhibition of pathogens in foods or food contact surfaces. To develop a and "green" food-grade alternative chemical sanitizers, we formulated multicomponent mixture containing Rosmarinus officinalis L., Camellia sinensis citric acid, ε-polylysine evaluated its bactericidal efficacy against Staphylococcus...
Contrary to other solid catalysts, enzymes facilitate more sophisticated chemical reactions because most specifically interact with substrates and release selective products. Lipases (triacylglycerol hydrolase, EC 3.1.1.3), which can catalyze the cleavage formation of various acyl compounds, are one best examples a unique substrate selectivity. There already several commercialized lipases that have become important tools for lipid-related studies, although there is still need discover novel...
RGD-conjugated Tetronic–tyramine (RGD–Tet–TA) hydrogels were formed in situ, and cell attachment spreading on the evaluated for an injectable tissue-regenerative scaffold. The prepared by simple mixing GRGDGGGGGY (RGD–Y) a tyramine-conjugated Tetronic (Tet–TA) polymer solution presence of horseradish peroxidase (HRP) hydrogen peroxide (H2O2). physico-chemical properties such as mechanical swelling ratio conjugated RGD concentration distribution measured using fluoresamine assay fluorescence...
Vinyl sulfone-terminated polyethylene glycol-poly(l-lactide) (VS−PEG−PLLA) diblock copolymer was designed as an amphiphilic structure containing a VS group with high reactivity toward thiols. Prior to the synthesis, heterobifunctional PEG at one terminus prepared and then PLLA introduced other end of PEG. The chemical molecular weight resulting products assigned by 1H NMR GPC. As micellar properties VS−PEG−PLLA under aqueous environment, critical micelle concentration mean size were found be...
Abstract In the present study, Δbackscattering (Δ BS ) method was developed as a simple and sensitive tool for determining emulsion stability index ( ESI by backscattering light detection. The detection uses emulsion‐scanning technology to monitor physical behavior in an function of storage time. Emulsions were prepared homogenization (8,000 rpm 2 min at 25C) distilled water perilla oil containing Tween 60, sample quiescently incubated vial 25C 11 h. To confirm this new methodology, sum Δ...
