Comparative analysis of early versus late surgical intervention for lumbosacral hemivertebra: a minimum 2-year follow-up retrospective study.

Background Context: Lumbosacral hemivertebra (LSHV) is a complex and unique congenital spinal deformity characterized by early severe trunk imbalance and progressive compensatory curve. Previous studies have proved the efficiency of posterior LSHV resection. However, the optimal timing for surgical intervention of LSHV still remains controversial.

Deciphering the Formation of Fe(IV) in the Fe(II)/Peroxydisulfate Process: The Critical Role of Sulfate Radical.

This study delves into the formation of ferryl ions (Fe(IV)) within the Fe(II)/peroxydisulfate (PDS) process, a pivotal reaction in advanced oxidation processes (AOPs) aimed at organic pollutant removal. Our findings challenge the conventional view that Fe(IV) predominantly forms through oxygen transfer from PDS to Fe(II), revealing that sulfate radicals (SO) play a crucial role in Fe(IV) generation. By employing competitive kinetics, the second-order rate constant for Fe(III) oxidation by SO was quantified as 4.

Trade-off between sulfidated zero-valent iron reactivity and air stability: Regulation of iron sulfides by ammonium dihydrogen phosphate.

The reactivity and stability of zero-valent iron (ZVI) and sulfidated zero-valent iron (S-ZVI) are inherently contradictory. Iron sulfides (FeS) on the S-ZVI surface play multiple roles, including electrostatic adsorption and catalyzing reduction. We proposed to balance the reactivity and air stability of S-ZVI by regulating FeS.

Treatment of Leakage Following Sleeve Gastrectomy by Laparo-Endoscopic Gastrostomy (LEG).

Sleeve gastrectomy (SG) is widely recognized as the leading bariatric procedure worldwide. However, leakage, its major complication, remains a significant concern. This study focuses on the challenges of managing leakage, especially when conventional endoscopic treatments are ineffective.

Gastrosplenic Fistula and/or Splenic Abscess: A Rare and Refractory Complication Following Sleeve Gastrectomy.

Splenic abscess is a rare complication often associated with sleeve gastrectomy (SG) due to factors including local infections, distant infections, tumors, ischemia, and trauma, which presents substantial challenges. We report four cases of gastrosplenic fistula and/or splenic abscess after SG. Patient data, including demographics, comorbidities, diagnostic procedures, treatments, and outcomes, were recorded.

Strong enhancement of third harmonic generation from a Tamm plasmon multilayer structure with WS.

Improving the conversion efficiency is particularly important for the generation and applications of harmonic waves in optical microstructures. Herein, we propose to enhance the efficiency of third harmonic generation by integrating a monolayer WS with the metal/dielectric/photonic crystal multilayer structure. The numerical simulations show that the multilayer structure enables to generate the Tamm plasmon mode between the metal film and photonic crystal around the telecommunication wavelength, which is consistent with the experimental result.

Development of diffusive gradients in thin-films technique for monitoring polycyclic aromatic hydrocarbons in coastal waters.

Addressing the challenge of accurately monitoring polycyclic aromatic hydrocarbons (PAHs) in aquatic systems, this study employed diffusive gradients in thin-films (DGT) technique to achieve methods detection limits as low as 0.02 ng L to 0.05 ng L through in situ preconcentration and determination of time-integrated concentrations.

Sprayed PAA-CaO nanoparticles combined with calcium ions and reactive oxygen species for antibacterial and wound healing.

The most common socioeconomic healthcare issues in clinical are burns, surgical incisions and other skin injuries. Skin lesion healing can be achieved with nanomedicines and other drug application techniques. This study developed a nano-spray based on cross-linked amorphous calcium peroxide (CaO) nanoparticles of polyacrylic acid (PAA) for treating skin wounds (PAA-CaO nanoparticles).

Overcoming defensive responding in the estimation of prevalence of non-medical use of prescription stimulants.

Background: Prevalence of Non-Medical Use of Prescription Stimulants (NMUPS) is estimated to be high among young adults enrolled in college. However, precise estimation of the prevalence of NMUPS is challenging owing to biases affecting self-report of sensitive and potentially illegal behaviors.

Objective: This study aimed to estimate the prevalence and risk factors of NMUPS using the crosswise randomized response technique (CRRT) and compare findings to the traditionally-used direct self-report (DSR) method.

Optimum Reaction Conditions for the Synthesis of Selenized Ait. (Liliaceae) Polysaccharides and Measurement of Their Antioxidant Activity In Vivo.

This study determined the optimum reaction conditions for synthesizing selenium-containing polysaccharides. Polysaccharide IIA (with the highest yield) from Ait. (Liliaceae) (OCAPIIA) was extracted and purified.

Enhanced Ca-Dependent SK-Channel Gating and Membrane Trafficking in Human Atrial Fibrillation.

Background: Small-conductance Ca-activated K (SK)-channel inhibitors have antiarrhythmic effects in animal models of atrial fibrillation (AF), presenting a potential novel antiarrhythmic option. However, the regulation of SK-channels in human atrial cardiomyocytes and its modification in patients with AF are poorly understood and were the object of this study.

Methods: Apamin-sensitive SK-channel current (I) and action potentials were recorded in human right-atrial cardiomyocytes from sinus rhythm control (Ctl) patients or patients with (long-standing persistent) chronic AF (cAF).

Hand-Sewn Gastrojejunostomy In Situ to Solve Acute Anastomotic Stricture Due to Submucosal Tunneling in Gastric Bypass.

Roux-en-Y gastric bypass (RYGB) is the second most widely used bariatric surgical procedure for morbid obesity and its related comorbidities. Anastomotic stricture is one of the major complications after RYGB. Submucosal tunneling is a rare cause of anastomotic stricture or occlusion, and clinical symptoms will appear soon after surgery.

Could manganate be an alternative of permanganate for micropollutant abatement?

Permanganate (MnO), an oxidant that has been applied in water treatment, has highly varied reactivity toward pollutants. In this study, we found manganate (MnO) could destruct diverse functional groups, with oxidation rates being higher than that of permanganate under acidic and neutral conditions. Mechanistic study revealed manganate rapidly disproportionated to permanganate and colloidal MnO in solution.

The alterations of circulating mucosal-associated invariant T cells in polycystic ovary syndrome.

Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting reproductive age females and an important cause of infertility. Although the etiology is complex and its pathogenesis remains unclear, the pathological process of PCOS is tightly related with the immune dysfunction and gut microbial dysbiosis. Mucosal-associated invariant T (MAIT) cells are a subset of innate-like T cells which can regulate inflammation through the production of cytokines and play a role in regulating the gut microbiota.

Clinical Application of the Roussouly Classification in the Sagittal Balance Reconstruction of 101 Adolescent Idiopathic Scoliosis Patients.

Purpose: Although Roussouly classification has been widely used in spinal surgery, it was mainly applied to degenerative scoliosis patients and correlational studies concerning adolescent idiopathic scoliosis (AIS) are still insufficient. This retrospective study explored the clinical application of Roussouly classification in surgeries and prognosis prediction for AIS.

Methods: This clinical research selected 101 AIS patients who received surgeries between August 2005 and November 2019.
