Analysis of faulting destruction and water supply pipeline damage from the first mainshock of the February 6,2023 Türkiye earthquake doublet

In 2023,two consecutive earthquakes exceeding a magnitude of 7 occurred in Türkiye,causing severe casualties and economic losses.The damage to critical urban infrastructure and building structures,including highways,railroads,and water supply pipelines,was particularly severe in areas where these structures intersected the seismogenic fault.Critical infrastructure projects that traverse active faults are susceptible to the influence of fault movement,pulse velocity,and ground motions.In this study,we used a unique approach to analyze the acceleration records obtained from the seismic station array(9 strong ground motion stations)located along the East Anatolian Fault(the seismogenic fault of the MW7.8 mainshock of the 2023 Türkiye earthquake doublet).The acceleration records were filtered and integrated to obtain the velocity and displacement time histories.We used the results of an on-site investigation,jointly conducted by China Earthquake Administration and Türkiye’s AFAD,to analyze the distribution of PGA,PGV,and PGD recorded by the strong motion array of the East Anatolian Fault.We found that the maximum horizontal PGA in this earthquake was 3.0 g,and the maximum co-seismic surface displacement caused by the East Anatolian Fault rupture was 6.50 m.As the fault rupture propagated southwest,the velocity pulse caused by the directional effect of the rupture increased gradually,with the maximum PGA reaching 162.3 cm/s.We also discussed the seismic safety of critical infrastructure projects traversing active faults,using two case studies of water supply pipelines in Türkiye that were damaged by earthquakes.We used a three-dimensional finite element model of the PE(polyethylene)water pipeline at the Islahiye State Hospital and fault displacement observations obtained through on-site investigation to analyze pipeline failure mechanisms.We further investigated the effect of the fault-crossing angle on seismic safety of a pipeline,based on our analysis and the failure performance of the large-diameter Thames Water pipeline during the 1999 Kocaeli earthquake.The seismic method of buried pipelines crossing the fault was summarized.

Role of ACLY in the development of gastric cancer under hyperglycemic conditions

To investigate the impact of hyperglycemia on the prognosis of patients with gastric cancer and identify key molecules associated with high glucose levels in gastric cancer development,RNA sequencing data and clinical features of gastric cancer patients were obtained from The Cancer Genome Atlas(TCGA)database.High glucose-related genes strongly associated with gastric cancer were identified using weighted gene co-expression network and differential analyses.A gastric cancer prognosis signature was constructed based on these genes and patients were categorized into high-and low-risk groups.The immune statuses of the two patient groups were compared.ATP citrate lyase(ACLY),a gene significantly related to the prognosis,was found to be upregulated upon high-glucose stimulation.Immunohistochemistry and molecular analyses confirmed high ACLY expression in gastric cancer tissues and cells.Gene Set Enrichment Analysis(GSEA)revealed the involvement of ACLY in cell cycle and DNA replication processes.Inhibition of ACLY affected the proliferation and migration of gastric cancer cells induced by high glucose levels.These findings suggest that ACLY,as a high glucose-related gene,plays a critical role in gastric cancer progression.

Herbal formula BaWeiBaiDuSan alleviates polymicrobial sepsis-induced liver injury via increasing the gut microbiota Lactobacillus johnsonii and regulating macrophage anti-inflammatory activity in mice

Sepsis-induced liver injury(SILI)is an important cause of septicemia deaths.BaWeiBaiDuSan(BWBDS)was extracted from a formula of Panax ginseng C.A.Meyer,Lilium brownie F.E.Brown ex Miellez var.viridulum Baker,Polygonatum sibiricum Delar.ex Redoute,Lonicera japonica Thunb.,Hippophae rhamnoides Linn.,Amygdalus Communis Vas,Platycodon grandiflorus(Jacq.)A.DC.,and Cortex Phelloderdri.Herein,we investigated whether the BWBDS treatment could reverse SILI by the mechanism of modulating gut microbiota.BWBDS protected mice against SILI,which was associated with promoting macrophage anti-inflammatory activity and enhancing intestinal integrity.BWBDS selectively promoted the growth of Lactobacillus johnsonii(L.johnsonii)in cecal ligation and puncture treated mice.Fecal microbiota transplantation treatment indicated that gut bacteria correlated with sepsis and was required for BWBDS anti-sepsis effects.Notably,L.johnsonii significantly reduced SILI by promoting macrophage anti-inflammatory activity,increasing interleukin-10+M2 macrophage production and enhancing intestinal integrity.Furthermore,heat inactivation L.johnsonii(HI-L.johnsonii)treatment promoted macrophage anti-inflammatory activity and alleviated SILI.Our findings revealed BWBDS and gut microbiota L.johnsonii as novel prebiotic and probiotic that may be used to treat SILI.The potential underlying mechanism was at least in part,via L.johnsonii-dependent immune regulation and interleukin-10+M2 macrophage production.
