Multi-metal ions co-regulated vanadium oxide cathode toward long-life aqueous zinc-ion batteries.

Interlayer intercalation engineering shows great feasibility to improve the structure stability of the layered oxides. Although high Zn-storage capability has been attained based on the pillar effect of multifarious intercalants, an in-depth understanding the synergistic effect of intercalated multiple metal ions is still in deficiency. Herein, alkali metal ion K, alkaline earth metal ion Mg and trivalent metal ion Al are introduced into the VO interlayer of VO.

Rare earth elements induced electronic engineering in Rh cluster toward efficient alkaline hydrogen evolution reaction.

The unique electronic and crystal structures of rare earth metals (RE) offer promising opportunities for enhancing the hydrogen evolution reaction (HER) properties of materials. In this work, a series of RE (Sm, Nd, Pr and Ho)-doped Rh@NSPC (NSPC stands for N, S co-doped porous carbon nanosheets) with sizes less than 2 nm are prepared, utilizing a simple, rapid and solvent-free joule-heat pyrolysis method for the first time. The optimized Sm-Rh@NSPC achieves HER performance.

Revision Total Hip Arthroplasty with Severe Acetabular Defect: A Preliminary Exploration and Attempt of Robotic-Assisted Technology.

Background: Robotic-assisted technology may be useful in hip revision cases with acetabular defects. However, data on the use of robotic-assisted technology for such complex diseases is lacking.

Case Presentation: This case study described the adoption of MAKO robotic-assisted treatment of revision total hip arthroplasty (THA) combined with severe acetabular defect (Paprosky type IIIB).

Xanthatin inhibits corneal neovascularization by inhibiting the VEGFR2‑mediated STAT3/PI3K/Akt signaling pathway.

Alkali burn is one of the main causes of corneal injury. The inflammation and neovascularization caused by alkali burns aggravate corneal damage, resulting in loss of vision. The aim of the present study was to evaluate the efficacy of xanthatin in the treatment of alkali burn‑induced inflammation and neovascularization.

Altered intrinsic brain activities in patients with acute eye pain using amplitude of low-frequency fluctuation: a resting-state fMRI study.

Objective: Many previous studies have reported that pain symptoms can lead to significant brain function and anatomical changes, whereas the intrinsic brain activity changes in acute eye pain (EP) patients remain unknown. Using the amplitude of low-frequency fluctuation (ALFF) method, this study aimed to evaluate the spontaneous brain activity alterations and their relationships with clinical features in acute EP patients.

Participants And Methods: A total of 20 patients with EP (15 males and 5 females) and 20 healthy controls (HCs; 15 males and 5 females) closely matched in age, sex, and education underwent resting-state functional magnetic resonance imaging scans.

[Levels of IL-8,IL-10 in patients with chronic periodontitis and coronary heart disease].

Purpose: To detect the level of interleukin-8 (IL-8) and interleukin-10 (IL-10) in serum and gingival crevicular fluid in patients with chronic severe periodontitis (CP) and coronary heart disease (CHD) and investigate the relationship between CP and CHD.

Methods: Thirty patients with CHD and CP(group A), twenty-five patients with only CP(group B) and thirty healthy controls (group C) were included in this study. Gingival crevicular fluid and serum IL-8, IL-10 levels were detected by ELISA.

[Elimination of interference in the determination of selenium in high purity tellurium by HG-AFS].

The samples were decomposed with HNCO3 +HCl, and Fe(3+)-citric acid mix solution was added to eliminate interferences. The elimination and mechanism of tellurium interference with selenium determination by HG-AFS were studied, and the residuary influence of NO3- and NO2- was investigated. The interference of ferric trichloride, hydrochloric acid, citric acid and PBH concentration with the fluorescence intensity of selenium was observed by the orthogonal test design combined with the mono-factor test.
