Objective The efficacy of sirolimus in treating severe or refractory systemic lupus erythematosus (SLE) has been confirmed by small-scale clinical trials. However, few studies focused on mild moderate SLE. Therefore, this study we elucidated add-on patients with Methods Data 17 consecutive SLE were retrospectively collected. Disease Activity Index-2000 (SLEDAI-2K), manifestation, laboratory data and peripheral T lymphocyte subsets cytokines collected before 6 months after treatment. cell...

T cells play a crucial role in the pathogenesis of systemic lupus erythematosus (SLE), with their functions regulated by various metabolic pathways. This study explores SLE and therapeutic effects human umbilical cord-derived mesenchymal stem (hUC-MSCs) via reprogramming. Clinical data peripheral blood samples were collected from 15 patients matched healthy controls. CD4+ isolated activated vitro anti-CD3/CD28. Following 72 h co-culture hUC-MSCs, cell viability was assessed using CCK-8...

Despite their potential for biodiesel synthesis, directly calcined minerals rich in magnesium/calcium carbonates are used at the expense of large amounts catalyst, high alcohol loading, long processing times, and severe conditions. We report a facile low-cost route preparing porous calcite (CPC) dolomite (CPD) via simple thermal decomposition reaction mixtures natural with stearic acid. CPC CPD, both which have structures, were compared previously reported catalysts examined as promising...

Au@Pt nanozyme, a bimetallic core–shell structure Au and Pt nanoparticle, has attracted significant attention due to its excellent catalytic activity stability. Here, we propose that improves glucose tolerance reduces TG after four weeks administration. The transcriptomic analysis of mouse liver tissues treated with nanozyme showed changes in genes related lipid metabolism signaling pathways, including glycolysis/gluconeogenesis, pyruvate metabolism, PPAR signaling, insulin signaling....

Heterogeneous catalysis using sole metal-organic frameworks (MOFs) remains an immature field because these MOFs have insufficient active sites. The “inorganic effect” allows to become solid supports immobilize polyoxometalates and metal nanoparticles, whereas the “organic enables function with organic groups such as -NH2 -SO3H. These functionalized can be applied in various reactions, oxidation, hydrogenation, Knoevenagel condensation, dehydration, hydrolysis. This review presents catalytic...

The effective prevention of plant bacterial infections has been complicated and challenged by unceasing resistance. application traditional bactericides achieved certain effects to alleviate this situation. However, these chemicals also have limitations, such as short half-life in reality, limited bioavailability, pollutant emission from their formulations. These disadvantages drive the demand for promoting antibacterial therapeutics. Self-assembled nanostructures based on amphiphiles...

Using β-cyclodextrins (β-CD) as raw material, [β-CD-2-C3Im]+[OH]– and [β-CD-6-C3Im]+[OH]– ionic liquids were prepared, further applied for biodiesel production. The results showed that the catalytic activity of [β-CD-6-C3Im]+[OH]− (6-ILs) was higher than [β-CD-2-C3Im]+[OH]− (2-ILs) because 6-ILs had larger specific surface area base strength. Systematic studies indicated interaction between cyclodextrin cavity triglyceride molecules affected role basic active sites ester groups.

Three-dimensional (3D) ZnO hierarchical microspheres composed of well-ordered nanorods were synthesized by a facile one-step hydrothermal method without any surfactants. The effects reaction conditions including temperature, time on the microstructure investigated. results demonstrated that played an important role in morphology 3D microspheres. A three-stage mechanism was proposed. Firstly, Zn2+ reacts with OH− and NH4+ to produce nanoparticles. Then nanoparticles are self-assembled into...

Biodiesel is a more attractive alternative fuel to diesel engines, because it renewable and nonpolluting that can be produced from plant animal fats. In this paper, two kinds of new nonedible herbaceous vegetable oils, including Leonurus artemisia L. (LAL) Peganum harmala (PHL), have been developed for biodiesel production. Their oil content, acid value, iodine value were found around 30.23 wt% 23.21wt%, 15.67 mg KOH/g 15.27 KOH/g, 116 I2/100 g 128 g, respectively. The fatty compositions...
