Objective: To investigate the protective effects of Gumibao recipe on glucocorticoid-included bone microcirculatory endothelial cell (BMEC) injury, and elucidate the possible underlying mechanism.

Methods: BMECs were treated with different concentrations of hydrocortisone at different time points, and the viability as well as migration of BMECs were evaluated; furthermore, the release of LDH, levels of VEGF, PAI-1, t-PA, and the content of NO by BMECs have been evaluated by commercially available kits; moreover, the expressions of eNOS, p-PI3K, p-Akt and p-mTOR in BMECs were examined by WB methods. Next, hydrocortisone treated BMECs were co-treated with Gumibao recipe, and the viability, migration and autophagy of BMECs were evaluated.

Metal-Catalyzed Carbon Foams Synthesized from Glucose as Highly Efficient Electromagnetic Absorbers.

This paper introduces a novel method for preparing high-performance, metal-containing carbon foam wave-absorbing materials. The process involves foaming glucose through catalysis by transition metals followed by high-temperature pyrolysis. The resulting carbon foam materials exhibit a highly porous structure, which is essential for their wave-absorption properties.

Microenvironment heterogeneity affected by anthropogenic wildfire-perturbed soil mediates bacterial community in forests.

Introduction: In recent years, the frequency and intensity of anthropogenic wildfires have drastically increased, significantly altering terrestrial ecosystems worldwide. These fires not only devastate vegetative cover but also impact soil environments and microbial communities, affecting ecosystem structure and function. The extent to which fire severity, soil depth, and their interaction influence these effects remains unclear, particularly in forests.

Retention and transport of PFOA and its fluorinated substitute, GenX, through water-saturated soil columns.

Perfluoro-2-propoxypropanoic acid (GenX) has emerged as a substitute for perfluorooctanoic acid (PFOA) especially since PFOA was listed among the persistent organic pollutants (POPs) by the Stockholm Convention in 2019. However, limited knowledge exists regarding the behavior and mobility of GenX in natural soils hindering the prediction of its environmental fate. This study investigated the mobility and retention of GenX and PFOA in soils under batch and water-saturated flow-through conditions.

Characteristics and mechanisms of resorption in lumbar disc herniation.

Lumbar disc herniation (LDH) can be spontaneously absorbed without surgical treatment. However, the pathogenesis and physiological indications for predicting protrusion reabsorption are still unclear, which prevents clinicians from preferentially choosing conservative treatment options for LDH patients with reabsorption effects. The purpose of this review was to summarize previous reports on LDH reabsorption and to discuss the clinical and imaging features that favor natural absorption.

Comprehensive adsorption behavior and mechanism of PFOA and PFCs in various subsurface systems in China.

The adsorption-desorption performance of perfluorooctanoic acid (PFOA), one of the environmentally persistent pollutants which is refractory to degrade in soil, was investigated and reported. The adsorption-desorption process of PFOA was firstly conducted using different fractions (sand, coarse silt and fine silt) of soil collected from Shanghai, China. More than 50% of PFOA (2.

Direct and efficient reduction of perfluorooctanoic acid using bimetallic catalyst supported on carbon.

A variety of metal elements have exhibited strong reductive and dehalogenative capabilities for the removal of persistent organic pollutants, owing to electron transfer or electron-hole activation through various methods. Herein, a bimetallic C-AlO structure (AlC) was successfully synthesized to simultaneously function as sorbent and catalyst in the reduction of perfluoroalkyl carboxylic acids (PFOA) polluted wastewater. Using a reaction period of 3 h, 98% of PFOA was removed by AlC through a mechanochemical stirring method and 70.

In Vitro and In Vivo Evaluations of β-Lactam/β-Lactamase Mono- and Combined Therapies against Carbapenem-Nonsusceptible Enterobacteriaceae in Taiwan.

Increasing carbapenem resistance rates worldwide underscored the urgent need of novel antimicrobials. Ceftazidime-avibactam and aztreonam-avibactam combinations are developed to combat carbapenem resistance, but biological and geographic variations must be considered for antibiotic susceptibility patterns varied. Thus, we sought to assess the susceptibilities of ceftazidime-avibactam and aztreonam-avibactam against 660 carbapenem-nonsusceptible Enterobacteriaceae isolates (472 and 188 ) collected during an earlier Taiwan surveillance study.

[Analysis of related factors and evaluation of quality of life of osteonecrosis of femoral head after internal fixation of femoral neck fracture].

Objective: To explore the risk factors of osteonecrosis of femoral head after internal fixation of femoral neck fracture in young patients, to describe the quality of life of patients with surviving femoral head, and to quantify the predictive factors.

Methods: From January 2013 to December 2016, 172 patients (174 hips) with femoral neck fracture treated by closed reduction and cannulated screw internal fixation were selected for retrospective analysis. The general data of the patients were summarized, including age, gender, body mass index, trauma mechanism, trauma operation interval, trauma season and whether the internal fixation was removed.

Green waste compost as a substitute for turfy soil in external-soil spray seeding substrate.

The scarcity of turfy soil (TS), which is the most commonly used external-soil spray seeding (ESSS) substrate component, has recently increased. The aim of this study was to introduce a substitute for TS as an organic matter additive in substrate. Green waste compost (GWC) that was combined with sandy loam soil, polyacrylamide (PAM), and super absorbent polymer (SAP) was used for preparing the soil substrate.

A novel fluorescent probe (dtpa-bis(cytosine)) for detection of Eu(III) in rare earth metal ions.

In this paper, a novel fluorescent probe, dtpa-bis(cytosine), was designed and synthesized for detecting europium (Eu) ion. Upon addition of Eu ions into the dtpa-bis(cytosine) solution, the fluorescence intensity can strongly be enhanced. Conversely, adding other rare earth metal ions, such as Y, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Yb and Lu, into dtpa-bis(cytosine) solution, the fluorescence intensity is decreased slightly.
