Enhancing compressive strength and durability of self-compacting concrete modified with controlled-burnt

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 2,   Pages 161-174 doi: 10.1007/s11709-021-0796-7

Abstract: showed that the presence of amorphous silica was detected for the processed SBA, revealing that the strengthThe compressive strength of SCC containing SBA (without BFS) could reach 98%−127% of that of the control; combination of SBA and 30% BFS gets a similar strength to the control after 28 d.Finally, a hyperbolic formula for interpolating the compressive strength of the SBA-based SCC was proposed

Lingguizhugan Decoction, a Chinese herbal formula, improves insulin resistance in overweight/obese subjects

Frontiers of Medicine 2022, Volume 16, Issue 5,   Pages 745-759 doi: 10.1007/s11684-021-0880-3

Abstract: Lingguizhugan Decoction (LGZG) has been investigated in basic studies, with satisfactory effects on insulin resistance in non-alcoholic fatty liver disease (NAFLD). This translational approach aimed to explore the effect and underlying mechanism of LGZG in clinical setting. A randomized, double-blinded, placebo-controlled trial was performed. A total of 243 eligible participants with NAFLD were equally allocated to receive LGZG (two groups: standard dose and low dose) or placebo for 12 weeks on the basis of lifestyle modifications. The primary efficacy variable was homeostasis model assessment of insulin resistance (HOMA-IR). Analyses were performed in two populations in accordance with body mass index (BMI; overweight/obese, BMI ≥ 24 kg/m2; lean, BMI < 24 kg/m 2). For overweight/obese participants, low-dose LGZG significantly decreased their HOMA-IR level compared with placebo (−0.19 (1.47) versus 0.08 (1.99),P = 0.038). For lean subjects, neither dose of LGZG showed a superior effect compared with placebo. Methylated DNA immunoprecipitation sequencing and real-time qPCR found that the DNA N6-methyladenine modification levels of protein phosphatase 1 regulatory subunit 3A (PPP1R3A) and autophagy related 3 (ATG3) significantly increased after LGZG intervention in overweight/obese population. Low-dose LGZG effectively improved insulin resistance in overweight/obese subjects with NAFLD. The underlying mechanism may be related to the regulation of DNA N6-methyladenine modification of PPP1R3A and ATG3. Lean subjects may not be a targeted population for LGZG.

Recovery of NH

Yang ZHANG,Zifu LI,Ibrahim B MAHMOOD

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 6,   Pages 825-834 doi: 10.1007/s11783-014-0682-9

Abstract: ion, a main pollutant in aquatic systems, not only causes eutrophication in rivers and lakes but also contributes to fish toxicity. In this study, an eco-friendly biosorbent was prepared from the pyrolysis of corn cob, a low-cost agricultural residue. The biochars produced by pyrolysis of corn cob at 400°C and 600°C were characterized and investigated as adsorbents for from an aqueous solution. The biochars were characterized through elemental analysis, Brunauer–Emmett–Teller–N surface area analysis, scanning electron microscopy, and Fourier transform infrared spectroscopy. Batch experiments were conducted to investigate the adsorption process of the corn cob biochars. The Freundlich isotherm model fitted the adsorption process better than the Langmuir and Dubinin–Radushkevich isotherm models. Moreover, the adsorption process was well described by a pseudo-second-order kinetic model. Results of thermodynamic analysis suggested that adsorption was a nonspontaneous exothermic process. Biochars produced at 400°C had higher adsorption capacity than those produced at 600°C because of the presence of polar functional groups with higher acidity. The exhausted biochar can be potentially used as soil conditioner, which can provide 6.37 kg (N fertilizer per ton of biochar).
