Seawater contains uranium at a concentration of ≈3.3 ppb, thus representing a rich and sustainable nuclear fuel source. Herein, an adsorption-electrocatalytic platform is developed for uranium extraction from seawater, comprising atomically dispersed indium anchored on hollow nitrogen-doped carbon capsules functionalized with flexible amidoxime moieties (In-Nx -C-R, where R denotes amidoxime groups). In-Nx -C-R exhibits excellent uranyl capture properties, enabling a uranium removal rate of 6.35 mg g-1 in 24 h, representing one of the best uranium extractants reported to date. Importantly, In-Nx -C-R demonstrates exceptional selectivity for uranium extraction relative to vanadium in seawater (8.75 times more selective for the former). X-ray absorption spectroscopy (XAS) reveals that the amidoxime groups serve as uranyl chelating sites, thus allowing selective adsorption over other ions. XAS and in situ Raman results directly indicate that the absorbed uranyl can be electrocatalytically reduced to an unstable U(V) intermediate, then re-oxidizes to U(VI) in the form of insoluble Na2 O(UO3 ·H2 O)x for collection, through reversible single electron transfer processes involving InNx sites. These results provide detailed mechanistic understanding of the uranium extraction process at a molecular level. This work provides a roadmap for the adsorption-electrocatalytic extraction of uranium from seawater, adding to the growing suite of technologies for harvesting valuable metals from the earth's oceans.
Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are neurodevelopmental disorders in need of innovative 'real-world' outcome measures to evaluate treatment effects. Instrumented gait analysis (IGA) using wearable technology offers a potentially feasible solution to measure "real-world' neurological and motor dysfunction in these groups.

Children (50% female; 6-16years) diagnosed with PWS (n=9) and AS (n=5) completed 'real-world' IGA assessments using the Physilog®5 wearable. PWS participants completed a laboratory assessment and a 'real-world' long walk. The AS group completed 'real-world' caregiver-assisted assessments. Mean and variability results for stride time, cadence, stance percentage (%) and stride length were extracted and compared across three different data reduction protocols.

The wearables approach was found to be feasible, with all participants able to complete at least one assessment. This study also demonstrated significant agreement, using Lin's concordance correlation coefficient (CCC), between laboratory and 'real-world' assessments in the PWS group for mean stride length, mean stance % and stance % CV (n=7, CCC 0.782-0.847, P=0.011-0.009).

'Real-world' gait analysis using the Physilog®5 wearable was feasible to efficiently assess neurological and motor dysfunction in children affected with PWS and AS.

In this paper, high transmittance (80.5% on glass) and low work function (2.92 eV) lithium fluoride (LiFx )/MgFx Oy electron contact stack by tailoring the composition of MgFx Oy hybrid film is reported. This hybrid structure exhibits a high conductivity (2978.4 S cm-1 ) and a low contact resistivity (2.0 mΩ cm2 ). The element profile of LiFx /MgFx Oy contact is measured and the reaction kinetics is analyzed. As a proof-of-concept, this electron selective contact is applied for dopant-free silicon solar cells. An impressive efficiency of 21.3% is achieved on dopant-free monofacial solar cell with molybdenum oxide (MoOx )/zinc-doped indium oxide (IZO) hole contact. An efficiency bifaciality of 71% is obtained for dopant-free bifacial solar cell with full-area LiFx /MgFx Oy /ITO (tin-doped indium oxide) transparent electron contact. It is the highest efficiency bifaciality so far for dopant-free bifacial solar cells to the best knowledge. Both cell configurations with LiFx /MgFx Oy contacts show excellent environment stability. The cell efficiency maintains more than 95% of its initial value after keeping in air for 1500 h. This work provides a new idea to achieve transparent electron contact, showing a great potential for high-efficiency and low-cost optoelectronic devices.Cadmium (Cd), an important toxic environmental pollutant, can invade the gastrointestinal tract and induce the occurrence of gastrointestinal diseases. This study aimed to investigate the protective effect of rice hull insoluble dietary fiber (RHF) on Cd-promoted colitis induced by low dose of dextran sulfate sodium. Administration of RHF attenuated inflammation by limiting Cd accumulation and regulating intestinal immune homeostasis in colitis mice with Cd exposure. RHF could maintain the structure of the gut barrier by increasing mucin secretion and intestinal tight connectivity in mice. Subsequently, RHF repressed the colonic inflammation mediated by the TLR4/MyD88/NF-κB pathway, and inhibited the transcription regulation of inflammatory cytokines. Furthermore, RHF showed an enhancement of a variety of probiotics, such as Eubacterium and Faecalibaculum. RHF also inhibited the growth of pathogenic bacteria, including Erysipelatoclostridium, Helicobacter and Bacteroides. The growth of beneficial bacteria was also accompanied by reversing the decline in short-chain fatty acids, supporting the initial potentiality of RHF as a prebiotic in cases of damage by Cd exposure in colitis mice. Importantly, RHF also remained resistant to Cd toxicity in colitis mice when the gut microbiota was depleted by antibiotics. We suggest that RHF could be used as a novel dietary supplement strategy against Cd-exacerbated colitis.Carbon monoxide (CO) is considered as the second gasotransmitter involved in a series of physiological and pathological processes. Although a number of organic fluorescent probes have been developed for imaging CO, these probes display excitation within the ultraviolet or visible range, which restrict their applications in the complex biosystems. In the present work, a strategy is developed to construct an upconversion nanoparticles-based nanosystem for upconversion luminescent (UCL) sensing CO. This nanosystem exhibits a fast response to CO with high sensitivity and selectivity in aqueous solution by a near-infrared-excited ratiometric UCL detection method. Meanwhile, laser scanning upconversion luminescence microscope experiments demonstrate that this nanosystem can visualize the endogenous CO bio-signaling in living cells, deep tissues, zebrafish, and living mice by ratiometric UCL imaging. In particular, this nanosystem has been successfully employed in visualization of the endogenous CO bio-signaling through up-regulation of heme oxygenase-1 (HO-1) in the progression of hypoxia, acute inflammation, or ischemic injury. This work demonstrates that the outstanding performance of the nanosystem not only can provide an effective tool for further understanding the role of CO in the physiological and pathological environment, but also may have great potential ability for tracking the expression of HO-1 in living systems.
Published studies have shown that several factors affect the development of C5 palsy after cervical open-door laminoplasty. As such, predicting its occurrence preoperatively is not possible. The current study aimed to uncover factors that can predict the development of C5 palsy before surgery by evaluating several different parameters.

A total of 177 patients who underwent surgery between 2015 and 2020 were included in the study. In total, C5 palsy was observed in 22 (12.4%) of our patients. The radiological and clinical data of the patients were retrospectively analyzed and added to the data.

A total of 177 patients who satisfied the criteria were included in the study, among whom 117 (66.1%) and 60 (33.9%) were male and female, respectively. Patients with ossified posterior longitudinal ligament (OPLL) (92; 52.0%) needed surgery the most. C5 palsy developed in 16/92 (17.3%) patients who had surgery for OPLL. This result was statistically significant (p 0.001). However, a significant difference in the postoperative Pavlov ratio was noted between both groups (p = 0.027). Selleckchem Androgen Receptor Antagonist The foraminal dimensions for the C5 palsy group were significantly lower than those for the non-C5 palsy group.

Smaller C5 root foramina diameter measurements were the most important predictive factor for the development of C5 palsy after open-door cervical laminoplasty. Although the pathophysiology remains to be fully understood, ischemia-reperfusion injury supposedly plays a role therein.

To evaluate the effect of early myelotomy on glutamate concentrations in injured spinal cord tissue with a weight drop spinal cord injury rat model.

The rats were assigned randomly to one of four groups, as follows in group I, rats underwent laminectomy; group II, myelotomy was performed after laminectomy; group III, rats received contusion after laminectomy; and group IV, myelotomy was performed 1 hour after laminectomy and contusion. In order to create a spinal cord injury, a 10-g rod was dropped from a height of 50 mm onto the exposed dura at T10 level. For the myelotomy procedure, a longitudinal 1-1.5 mm depth midline incision was made to the spinal cord. Twelve hours later, rats were decapitated, and the spinal cord tissues were removed. The obtained tissues' glutamate concentrations were measured using the HPLC technique.

The glutamate levels were significantly lower in group III than those of groups I and II. In group IV, glutamate levels were significantly high compared to group III and significantly low compared to group I. Between groups I and II, there was no statistically significant difference.

This study's results suggest that early myelotomy significantly prevented glutamate depletion from the injured spinal cord. Compared to the normal spinal cord, there was still significant depletion in injured spinal cord with myelotomy because of the initial glutamate release until the myelotomy was performed. It was also concluded that myelotomy was not harmful to the spinal cord as it did not cause significant glutamate depletion.

Vertebral compression fractures (VCF) occur most commonly at the thoracolumbar junction (TLJ). Balloon kyphoplasty (BKP) is an effective method of bone remodeling in these cases. In this study, we evaluate the parameters that affect bone retropulsion and restoration in TLJ VCF without neurological deficits.

Thirty-one of Frankel E and AO A3-4 type VCFs fractures at the TLJ, with bone retropulsion into the spinal canal, from 2017 to 2020, were evaluated retrospectively. Data was gathered on patient demographics and medical histories. Measurements of anterior vertebral heights, posterior vertebral heights, local kyphotic angles, spinal cord area, and bone retropulsion into the spinal canal (BRC) were evaluated preoperatively, early postoperatively, and late postoperatively.

In those patients who underwent early surgery ( 4 weeks postfracture), a significantly greater increase in anterior vertebral heights was seen between early postoperative and preoperative measurements than in patients who underwent late surgery ( 4 weeks postfracture) (p = 0.
