Recent advances in systemic lupus erythematosus and microbiota: from bench to bedside

Frontiers of Medicine 2022, Volume 16, Issue 5,   Pages 686-700 doi: 10.1007/s11684-022-0957-7

Abstract: Systemic lupus erythematosus (SLE) is a complicated autoimmune disease affecting multiple systems and organs. It is highly heterogeneous, and it preferentially affects women at childbearing age, causing worldwide social burden. The pathogenesis of SLE mostly involves genetic predisposition, epigenetic dysregulation, overactivation of the immune system, and environment factors. Human microbiome, which is mostly composed of microbiota colonized in the gut, skin, and oral cavity, provides a natural microbiome barrier against environmental risks. The past decade of research has demonstrated a strong association between microbiota and metabolic diseases or gastrointestinal diseases. However, the role of microbiota in autoimmunity remains largely unknown until recently, when the technological and methodological progress facilitates further microbiota research in SLE. In this review, the latest research about the role and mechanisms of microbiota in SLE and the advances in the development of diagnostic and therapeutic strategies based on microbiota for SLE were summarized.

A novel intravenous general anesthetic--- emulsified isoflurane: from bench to bedside

Cheng Zhou, Jin Liu

Frontiers of Medicine 2012, Volume 6, Issue 4,   Pages 381-387 doi: 10.1007/s11684-012-0229-z

Abstract:

Application of volatile anesthetics greatly alters modern medicine. There are obvious advantages of volatile anesthetics such as strong anesthetic potency, rapid onset and elimination through respiration system. Isoflurane is one of the most widely used volatile anesthetics in clinic. Emulsified isoflurane, the emulsion of isoflurane, is a novel intravenous general anesthetic. With the development of emulsified isoflurane in the past fifteen years, its utility has spread from intravenous general anesthesia to various fields including regional anesthesia, organ protection, as well as anesthetic pharmacological study. In this review, we will summarize literatures of emulsified isoflurane about its history, clinical application and future potential utility in the above mentioned fields.

Impact of total organic carbon and chlorine to ammonia ratio on nitrification in a bench-scale drinking

Yongji ZHANG, Lingling ZHOU, Guo ZENG, Huiping DENG, Guibai LI

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 4,   Pages 430-437 doi: 10.1007/s11783-010-0247-5

Abstract: Nitrification occurs in chloraminated drinking water systems and is affected by water quality parameters. The aim of this study was to investigate the impact of total organic carbon and chlorine to ammonia ratio on nitrification potential in a simulated drinking water distribution system as during chloramination. The occurrence of nitrification and activity of nitrifying bacteria was primarily monitored using four rotating annular bioreactors (RAB) with different chlorine to ammonia ratios and total organic carbon (TOC) levels. The results indicated that nitrification occurred despite at a low influent concentration of ammonia, and a high concentration of nitrite nitrogen was detected in the effluent. The study illustrated that reactors 1(R1) and 3 (R3), with higher TOC levels, produced more nitrite nitrogen, which was consistent with the ammonia-oxidizing bacteria (AOB) counts, and was linked to a relatively more rapid decay of chloramines in comparison to their counterparts (R2 and R4). The AOB and HPC counts were correlated during the biofilm formation with the establishment of nitrification. Biofilm AOB abundance was also higher in the high TOC reactors compared with the low TOC reactors. The chlorine to ammonia ratio did not have a significant impact on the occurrence of nitrification. Bulk water with a high TOC level supported the occurrence of nitrification, and AOB development occurred at all examined chlorine to ammonia dose ratios (3∶1 or 5∶1).

Prediction of the shear wave velocity

Amoroso SARA

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 1,   Pages 83-92 doi: 10.1007/s11709-013-0234-6

Abstract: The paper examines the correlations to obtain rough estimates of the shear wave velocity from non-seismic dilatometer tests (DMT) and cone penetration tests (CPT). While the direct measurement of is obviously preferable, these correlations may turn out useful in various circumstances. The experimental results at six international research sites suggest that the DMT predictions of from the parameters (material index), (horizontal stress index), (constrained modulus) are more reliable and consistent than the CPT predictions from (cone resistance), presumably because of the availability, by DMT, of the stress history index .

Strategic Study of CAE 2014, Volume 16, Issue 11,   Pages 36-41

Abstract:

This paper numerically simulates the stress development and generates a three-dimensional model of the medium-deep hole blasting in infinite rock mass for continuous charge and divided charge in blasting by using the large-scale nonlinear dynamic analysis software LS-DYNA and the elastic-plastic model *MAT_PLASTIC_KINEMATIC and JWO-EOS. The difference of the decreasing rate in Von Mises effective stress of blasting, element effective stress peak in free face, the bore wall stress and acceleration are investigated. It is shown that divided charge could greatly improve the blasting effect by engineering blasting practice.
