Ultrafast self-healing zwitterionic hydrogels reinforced by carboxymethyl chitosan-oxidized hyaluronic acid and graphene oxide toward high-performance strain sensors.

Inspired by the inherent recuperative ability of organisms in nature, researchers have dedicated significant efforts towards developing self-healing hydrogel sensors. Although the works on self-healing hydrogels have made great progress, achieving hydrogel sensors combining with rapid and efficient healing capability, excellent mechanical properties and high sensing sensitivity remains a challenging task. In this study, we proposed a novel approach for fabricating a self-healing conductive zwitterionic hydrogel sensor by adding carboxymethyl chitosan (CMCs) and oxidized hyaluronic acid (OHA) to induce dynamic Schiff base reaction, and graphene oxide (GO) nanosheets as physical crosslinker.

Non-Invasive Brain Stimulation Progression in Post-Stroke Depression Treatment: A Systematic Review.

Objective: Post-stroke depression (PSD) is the most common psychological disorder in patients with stroke. It not only seriously affects the patient's functional recovery, quality of life, and ability to return to society but also increases stroke recurrence rate and mortality. However, the effectiveness of drug treatment is unpredictable and associated with certain side effects and low compliance.

Fabrication of anti-freezing and self-healing hydrogel sensors based on carboxymethyl guar gum and poly(ionic liquid).

As classical soft materials, conductive hydrogels have attracted wide attention in the field of strain sensors due to their unique flexibility and conductivity. However, there are still challenges in developing conductive hydrogels with comprehensive mechanical strength, self-healing ability and sensitive sensing properties. In this paper, a novel PAV/CMGG hydrogel was prepared by a simple one-pot method through the introduction of 1-vinyl-3-butylimidazolium bromide (VBIMBr), acrylic acid (AA), carboxymethyl guar gum (CMGG) and AlCl.

Fair non-contact blood pressure estimation using imaging photoplethysmography.

Therefore, there is a need for a portable, non-contact method for estimating blood pressure.

Novel flexible hydrogels based on carboxymethyl guar gum and polyacrylic acid for ultra-highly sensitive and reliable strain and pressure sensors.

To realize on stable and real-time monitoring of human activities, novel hydrogels using polyacrylic acid (PAA) and carboxymethyl guar gum (CMGG) were fabricated as wearable and flexible strain or pressure sensors in the presence of lignosulfonate (LS) and Al.

The hydrogels displayed good self-adhesion behavior and an ultra-high tensile sensitivity (gauge factor (GF) = 24.

Evaluation of Relationships between Corticospinal Excitability and Somatosensory Deficits in the Acute and Subacute Phases of Stroke.

Background: Somatosensory deficits are common symptoms post stroke. Repetitive transcranial magnetic stimulation (rTMS) over the motor cortex is able to promote motor rehabilitation, whereby its impact on somatosensory functioning remains unknown. This study was designed to evaluate the association between somatosensory deficits and corticospinal excitability following stroke, with the purpose to provide insights on rTMS interventions for the management of somatosensory deficits.

Selective Cocatalyst Decoration of Narrow-Bandgap Broken-Gap Heterojunction for Directional Charge Transfer and High Photocatalytic Properties.

Narrow-bandgap semiconductors are promising photocatalysts facing the challenges of low photoredox potentials and high carrier recombination. Here, a broken-gap heterojunction Bi/Bi S /Bi/MnO /MnO , composed of narrow-bandgap semiconductors, is selectively decorated by Bi, MnO nanodots (NDs) to achieve robust photoredox ability. The Bi NDs insertion at the Bi S /MnO interface induces a vertical carrier migration to realize sufficient photoredox potentials to produce O and OH active species.

Sodium-Based Cylindrical Plasmonic Waveguides in the Near-Infrared.

Subwavelength optical field confinement and low-loss propagation are of great significance for compact photonic integration. However, the field confinement capability of plasmonic devices is always accompanied by the inherent Ohmic loss. Although recent studies have shown that sodium (Na) exhibits lower loss than noble metals in the near-infrared band, the field confinement ability has not been adequately assessed.

MiR-10b-3p Protects Cerebral I/R Injury through Targeting Programmed Cell Death 5 (PDCD5).

Previous studies have demonstrated that miR-10b-3p is significantly downregulated in rats after cerebral ischemia injury, and this study aimed to investigate the effect of miR-10b-3p in cerebral ischemia/reperfusion (I/R) injury. The oxygen-glucose deprivation (OGD) induced SH-SY5Y cell model and middle cerebral artery occlusion model (MCAO) rats were constructed to investigate the role of miR-10b-3p and underline the regulatory mechanism of miR-10b-3p/PDCD5 axis in cerebral I/R injury. The expression of miR-10b-3p and PDCD5 was evaluated by qRT-PCR and Western blot.

Single and simultaneous effects of naphthalene and salinity on anaerobic digestion: Response surface methodology, microbial community analysis and potential functions prediction.

Polycyclic aromatic hydrocarbons (PAHs) are a persistent and prevalent class of pollutants in petroleum-contaminated saline environment, which pose potential harm to organisms. Researches on anaerobic biodegradation of PAHs are gradually emerging, but the response of anaerobic microorganisms to salinity changes and the co-effects of salinity and PAHs in anaerobic digestion (AD) system have seldom been reported. Thus, we investigated the variations of AD system performance and anaerobic microbial community caused by different concentrations of naphthalene (Nap) or/and NaCl based on Box-Behnken Design (0 mg/L ≤ Nap ≤150 mg/L, 0 g/L ≤ NaCl ≤25 g/L).
