Abstract
Global polarization of Ξ and Ω hyperons has been measured for the first time in Au+Au collisions at sqrt[s_{NN}]=200 GeV. The measurements of the Ξ^{-} and Ξ[over ¯]^{+} hyperon polarization have been performed by two independent methods, via analysis of the angular distribution of the daughter particles in the parity violating weak decay Ξ→Λ+π, as well as by measuring the polarization of the daughter Λ hyperon, polarized via polarization transfer from its parent. The polarization, obtained by combining the results from the two methods and averaged over Ξ^{-} and Ξ[over ¯]^{+}, is measured to be ⟨P_{Ξ}⟩=0.47±0.10(stat)±0.23(syst)% for the collision centrality 20%-80%. The ⟨P_{Ξ}⟩ is found to be slightly larger than the inclusive Λ polarization and in reasonable agreement with a multiphase transport model. The ⟨P_{Ξ}⟩ is found to follow the centrality dependence of the vorticity predicted in the model, increasing toward more peripheral collisions. The global polarization of Ω, ⟨P_{Ω}⟩=1.11±0.87(stat)±1.97(syst)% was obtained by measuring the polarization of daughter Λ in the decay Ω→Λ+K, assuming the polarization transfer factor C_{ΩΛ}=1.

Abstract
Setting time and mechanical properties are key metrics needed to assess the properties of municipal solid waste incineration (MSWI) bottom ash alkali-activated samples. This study investigated the solidification law, polymerization, and strength development mechanism in response to NaOH and liquid sodium silicate addition. Scanning electron microscopy and X-ray diffraction were used to identify the formation rules of polymerization products and the mechanism of the underlying polymerization reaction under different excitation conditions. The results identify a strongly alkaline environment as the key factor for the dissolution of active substances as well as for the formation of polymerization products. The self-condensation reaction of liquid sodium silicate in the supersaturated state (caused by the loss of free water) is the major reason for the rapid coagulation of alkali-activated samples. The combination of both NaOH and liquid sodium silicate achieves the optimal effect, because they play a compatible coupling role.

Abstract
OBJECTIVE Fragile fracture patients need to be treated with long-term fixation and the recovery process is slow. Several studies have shown that the fracture healing process is related to gene expression. We aimed to investigate the role of long chain non-coding RNA TSIX (lncRNA TSIX) on fracture healing after tibial fracture (TF) and explore the molecular mechanism underlying its action. MATERIALS AND METHODS The male C57BL/6J mice were used to construct TF models and osteoblasts were used as in vitro model. The proliferation, apoptosis, and osteogenesis-related genes of Col1a1, Col-II, and Col-X were detected to evaluate the role of lncRNA TSIX in vivo and in vitro after TF. Haematoxylin-eosin (HE) staining was conducted to confirm the fracture healing conditions. RESULTS We found that LncRNA TSIX expression in plasma of TF mice significantly upregulated in a time-dependent manner. Overexpression of lncRNA TSIX could significantly inhibit proliferation but promote apoptosis and regulate the osteogenesis-related genes expression by binding and positively regulate sex-determining region Y box 6 (SOX6) expression, while knockdown of lncRNA TSIX showed the opposite effect in osteoblastic cells. Inhibition of lncRNA TSIX could improve fracture healing after TF. CONCLUSIONS Taken together, our study supported that knockdown of lncRNA TSIX could promote the tibia fracture healing by binding and inhibiting the SOX6 expression. We suggest that lncRNA TSIX/SOX may be the potential targets for the treatment of TF.

Abstract
OBJECTIVE Osteogenic differentiation of bone marrow stromal stem cells (BMSCs) is beneficial to the treatment of osteoarthritis (OA). Lnc-RNA BLACAT1 involves in occurrence and development of various diseases. However, the role of Lnc-RNA BLACAT1 in BMSCs differentiation under inflammation remains unclear. MATERIALS AND METHODS Rat BMSCs were isolated and randomly divided into control group and inflammation group (addition of IL-6). The inflammation group was further divided into BLACAT1 siRNA group and BLACAT1 siRNA+miR-142-5p inhibitor group, followed by analysis of Lnc-RNA BLACAT1 expression by real time PCR, BMSCs proliferation, Caspase 3 activity, ALP activity, expression of Runx2, OC and PPARγ2 by real time PCR, and secretion of TNF-α and IL-1β by enzyme-linked immunosorbent assay (ELISA). The bioinformatics software and the Luciferase reporter system analyze the targeted relationship between BLACAT1 and miR-142-5p. RESULTS In inflammation group, Lnc-BLACAT1 expression was increased, along with inhibited BMSCs proliferation, increased Caspase 3 activity, decreased ALP activity, and expression of Runx2 and OC, increased PPARγ2 expression and secretion of TNF-α and IL-1β. The difference was statistically significant compared with control group (p<0.05). MiR-142-5p is the target miRNA of Lnc-RNA BLACAT1. BLACAT1 siRNA down-regulated BLACAT1 expression, promoted cell proliferation, inhibited Caspase 3 activity, increased ALP activity and Runx2 and OC expression, decreased PPARγ2 expression and TNF-α and IL-1β secretion. Compared with inflammation group, the difference was statistically significant (p<0.05). Of note, BLACAT1 siRNA+miR-142-5p inhibitor group reversed the effect of siRNA-mediated knockdown of BLACAT1. CONCLUSIONS Lnc-RNA BLACAT1 expression was increased in inflammatory BMSCs, and knockdown of BLACAT1 promoted proliferation and osteogenic differentiation of BMSCs targeting miR-142-5p.

Abstract
Nonmonotonic variation with collision energy (sqrt[s_{NN}]) of the moments of the net-baryon number distribution in heavy-ion collisions, related to the correlation length and the susceptibilities of the system, is suggested as a signature for the quantum chromodynamics critical point. We report the first evidence of a nonmonotonic variation in the kurtosis times variance of the net-proton number (proxy for net-baryon number) distribution as a function of sqrt[s_{NN}] with 3.1 σ significance for head-on (central) gold-on-gold (Au+Au) collisions measured solenoidal tracker at Relativistic Heavy Ion Collider. Data in noncentral Au+Au collisions and models of heavy-ion collisions without a critical point show a monotonic variation as a function of sqrt[s_{NN}].

Abstract
Objective: To explore the feasibility, safety and effectiveness of anatomical partial lobectomy. Methods: The clinical data of 3 336 patients with lung nodules underwent anatomical partial lobectomy in our center from November 2013 to November 2019 were retrospectively analyzed. We set the safety margin distance according to the imaging feature of the lesion. The surgeons then anatomically detached the major vessels and bronchus in this region, resected the targeted lung tissue along the plane, and completed the resection of anatomical pulmonary lobe and clean and sampling of systemic lymph nodules. Results: A total of 668 cases were multiple nodules and 2 668 cases were solitary pulmonary nodules. According to the postoperative pathological results, 283 cases were benign, 1 197 cases were preinvasive lesions (including 38 cases of atypical adenomatous hyperplasia, 445 cases of adenocarcinoma in situ and 714 cases of minimally invasive adenocarcinoma), 1 713 cases were invasive adenocarcinoma, 73 cases were non-adenocarcinoma and 70 cases were metastatic carcinoma. Among 1 786 invasive primary lung cancers, 11 cases received preoperative neoadjuvant chemotherapy, and their postoperative pathologic diagnoses were stage ypIA. Other 1 775 cases who did not receive postoperative neoadjuvant treatment included 1 587 cases in stage ⅠA, 112 cases in stage ⅠB, 3 cases in stage ⅡA, 18 cases in stage ⅡB, 37 cases in stage ⅢA, 9 cases in stage ⅢB, 9 cases in stage Ⅳ. The average operation time was (127.3±55.3) minutes, and the mean postoperative hospital stay was (4.8±2.4) days. The incidence rate of complications (grade>2) was 1.1%(38/3 336), and no death occurred during 30 days after operation. Conclusion: Anatomic partial lobectomy has good clinical applicability, safety and effectiveness, which is worthy of clinical application and recommendation.

Abstract
The necrosome is a large-molecular-weight complex in which the terminal effector of the necroptotic pathway, Mixed Lineage Kinase Domain-Like protein (MLKL), is activated to induce necroptotic cell death. The precise mechanism of MLKL activation by the upstream kinase, Receptor Interacting Serine/Threonine Protein Kinase 3 (RIPK3) and the role of Receptor Interacting Serine/Threonine Protein Kinase 1 (RIPK1) in mediating MLKL activation remain incompletely understood. Here, we reconstituted human necrosome interactions in yeast by inducible expression of these necrosome effectors. Functional interactions were reflected by the detection of phosphorylated MLKL, plasma membrane permeabilization, and reduced proliferative potential. Following overexpression of human necrosome effectors in yeast, MLKL aggregated in the periphery of the cell, permeabilized the plasma membrane and compromised clonogenic potential. RIPK1 had little impact on RIPK3/MLKL-mediated yeast lethality; however, it exacerbated the toxicity provoked by co-expression of MLKL with a RIPK3 variant bearing a mutated RHIM-domain. Small molecule necroptotic inhibitors necrostatin-1 and TC13172, and viral inhibitors M45 (residues 1–90) and BAV_Rmil, abated the yeast toxicity triggered by the reconstituted necrosome. This yeast model provides a convenient tool to study necrosome protein interactions and to screen for and characterize potential necroptotic inhibitors.

Abstract
Toxoplasma gondii is an obligate intracellular protozoan parasite that can infect all nucleated cells through active invasion. Some non-canonical pathways for T. gondii infection of macrophages have recently been reported. We report a new mode of T. gondii invasion using a time-lapse imaging system, in which T. gondii tachyzoites are engulfed by a tube-like structure on peritoneal macrophage phagosomes and then escape from the phagosomes. Escaped parasites re-invade macrophages through intercellular junctions between their apical end and host cell membranes. We call this invasion pathway of T. gondii "pseudopod-assisted invasion" (PAI). The completion of this invasion process depends on parasitic motility and secretion of adhesins from parasitic micronemes. Our results provide new information about T. gondii infection and establish another platform for studying interactions between T. gondii and macrophages.

Abstract
AbstractRed mud, a by-product of alumina production, has a great impact on the environment due to its high alkalinity. In this paper, two-part geopolymer mortar was synthesized by combining red mud and blast furnace slag (BFS) to obtain optimized compressive strength and flexural strength for construction materials. Geopolymer concrete was prepared with the cementitious material in the concrete replaced by geopolymer mortar. Mechanical properties, permeability and microscopic properties of geopolymer concrete were measured. The results showed that the compressive strength grade of concrete prepared with geopolymer concrete can reach 54.43 MPa indicating that the geopolymer concrete can be used as materials for load-bearing members in structures. Due to lower total porosity and better pore structure, the permeability resistance of geopolymer concrete was significantly better than ordinary concrete. Microscopic analysis indicated that a large amount of aluminosilicate reaction products was generated in a geopolymer by the reaction of OH− with the aluminosilicate components in red mud and BFS in a strongly alkaline environment. The surface [SiO4]4− and [AlO4]4− tetrahedrons form chemical bonds through dehydroxylation, which is the direct reason for their high strength and determines their excellent physical and chemical properties.

PARTICIPANTS Patients (n=120) diagnosed clinically as probable AD and in stable condition from Tianjin Key Laboratory of Cerebrovascular and Neurodegenerative Diseases. MEASUREMENTS Individuals were randomly divided into the intervention group (n=60, folic acid 1.2 mg/d + vitamin B12 50 μg/d) and the placebo group (n=60). Cognitive performance, blood folate, vitamin B12, one carbon cycle metabolite, and inflammatory cytokine levels were measured at baseline and after 6 months. The data were analyzed using linear mixed models for repeated measures. RESULTS A total of 101 participants (51 in the intervention group and 50 in the placebo group) completed the trial. Folic acid plus vitamin B12 supplementation had a beneficial effect on the MoCA total scores (P=0.029), naming scores (P=0.013), orientation scores (P=0.004), and ADAS-Cog domain score of attention (P=0.008), as compared to those of the control subjects. Moreover, supplementation significantly increased plasma SAM (P<0.001) and SAM/SAH (P<0.001), and significantly decreased the levels of serum Hcy (P<0.001), plasma SAH (P<0.001), and serum TNFα (P<0.001) compared to in the control subjects. CONCLUSIONS Folic acid and vitamin B12 supplementation showed a positive therapeutic effect in AD patients who were not on a folic acid-fortified diet. The findings of this study help to delineate nutrient intervention as far as public health management for the prevention of dementia is concerned.

Abstract
Background: Toxoplasma gondii is an obligate intracellular parasite, which can infect all nucleated cells in a variety of vertebrate animals, including human, causing toxoplasmosis. Although a number of studies have reported on the seroprevalence of T. gondii infection in dogs in China, however, information about T. gondii infection in pet dogs in Anhui, China is not available. Methods: The modified agglutination test (MAT) was used to detect antibodies in sera samples from 468 pet dogs at Anhui Province in China from November 2013 to April 2017. Results: 18.6% animals were T. gondii seropositive, indicating a slightly higher prevalence of T. gondii infection in pet dogs in Anhui, China in comparison with other provinces in China. Conclusion: Our present study provided epidemiological data on T. gondii seroprevalence in pet dogs in Anhui, China for the effective prevention and control of the parasite prevalence in this area.

Abstract
Toxoplasma gondii (T. gondii) is a neurophilic and intracellular parasite that can affect plenty of vertebrate animals, including humans. Recent researches indicate that T. gondii infection is associated with neurodegenerative diseases such as Alzheimer's disease(AD). In addition, tau hyper-phosphorylation is a crucial event leading to the formation of nerve fiber tangles in AD. Despite the efforts to understand the interactions between T. gondii and AD, there are no clear results available so far. Here, we infected mice with the T. gondii of the Chinese 1 genotype Wh6 strain (TgCtwh6) for 60 days. Then we observed the formation of tissue cysts in the brain, the damage of neuron and the increased expression of phosphorylated tau (p-tau) in the hippocampal tissue of the mice. Similarly, we also found that p-tau, glycogen synthase kinase 3 beta (GSK3β), and phosphorylated GSK3β (p-GSK3β) were upregulated in vitro in TgCtwh6 challenged hippocampal neuron cell strain, HT22 cells. We noted a down-regulated expression of GSK3β,p-GSK3β, and p-tau in HT22 cells, which were pretreated with LiCl, an inhibitor of GSK3β. These data suggested that p-GSK3β may mediate tau phosphorylation after TgCtwh6 infection. Furthermore, TgCtwh6 infection also caused the increased expression of Bax and Caspase3, the decreased expression of Bcl-XL in HT22 cells, which had both early and late apoptosis. In all, our results indicated that TgCtwh6 infection not only led to phosphorylation of tau via activating GSK3β but also promoted hippocampal neuron apoptosis. Our research may partially reveal the mechanism with which TgCtwh6 induce neurofibrillary pathology.

Abstract
This study describes a simple method for the large‐scale isolation of pure Toxoplasma gondii tachyzoites and bradyzoites. T. gondii tachyzoites were obtained from infected human foreskin fibroblasts (HFFs) and peritoneal exudates of mice, while tissue cysts containing bradyzoites were collected from chronically infected mice. Harvested cells and brain tissues were incubated in Hanks balanced salt solution (HBSS), containing 0.25% trypsin and 0.5% taurodeoxycholic acid (TDC) for 5 min. Subsequent washes in phosphate buffered saline (PBS) were conducted, and the cell viability of the preparations was good, as determined by flow cytometry and ability to reinfect HFF cells and propagate in mice. The purification procedure allowed for a rapid preparation of pure T. gondii tachyzoites and bradyzoites in sufficient quantity that can be used for downstream procedures. The advantage of the new method is that it is convenient and inexpensive.

Abstract
AIM The aim of this study was to study the effects of salt concentrations on the microbial communities, physicochemical properties, metabolome profiles and sensory characteristics during the fermentation of traditional northeast sauerkraut. METHODS AND RESULTS Northeast sauerkraut was spontaneously fermented under four salt concentrations (0·5, 1·5, 2·5 and 3·5%, w/w). The result of microbiological analysis showed that the population of lactic acid bacteria in 2·5%-salted sauerkraut was significantly higher than that in the other samples. Correspondingly, the speed of decrease in pH and accumulation of acids were the highest in 2·5%-salted sauerkraut. The glucose (analysed by HPLC) in 2·5%-salted sauerkraut was consumed more completely to produce higher levels of organic acids compared to those in the other samples. Principle component analysis showed clear differences in the metabolites of sauerkraut according to different salt concentrations. A higher level of volatiles (detected by HS-SPME/GC-MS) was identified in 2·5%-salted sauerkraut, and sensory evaluation demonstrated that 2·5%-salted sauerkraut had the best sensory characteristics. CONCLUSION The best quality of sauerkraut was obtained from fermented under 2·5% salt concentration. SIGNIFICANCE AND IMPACT OF THE STUDY This study facilitated the understanding of the effects of salt on the sauerkraut fermentation and may be useful for developing the quality of sauerkraut.

Abstract
Glutathione S-transferases (GSTs) are members of a multifunctional enzyme superfamily. Forty-one GSTs have been identified in Tribolium castaneum; however, none of the 41 GSTs has been functionally characterized. Here, three delta-class GSTs, TcGSTd1, TcGSTd2 and TcGSTd3, of T. castaneum were successfully cloned and expressed in Escherichia coli. All of the studied GSTs catalysed the conjugation of reduced glutathione with 1-chloro-2,4-dinitrobenzene. Insecticide treatment showed that the expression levels of TcGSTd3 and TcGSTd2 were significantly increased after exposure to phoxim and lambda-cyhalothrin, whereas TcGSTd1 was slightly upregulated only in response to phoxim. A disc diffusion assay showed that overexpression of TcGSTD3, but not TcGSTD1 or TcGSTD2, in E. coli increased resistance to paraquat-induced oxidative stress. RNA interference knockdown of TcGSTd1 caused metamorphosis deficiencies and reduced fecundity by regulating insulin/target-of-rapamycin signalling pathway-mediated ecdysteroid biosynthesis, and knockdown of TcGSTd3 led to reduced fertility and a decreased hatch rate of the offspring, probably caused by the reduced antioxidative activity in the reproductive organs. These results indicate that TcGSTd3 and TcGSTd2 may play vital roles in cellular detoxification, whereas TcGSTd1 may play essential roles in normal development of T. castaneum. These delta-class GSTs in T. castaneum have obtained different functions during the evolution.

Abstract
We report on the first measurement of the charmed baryon Λ_{c}^{±} production at midrapidity (|y|<1) in Au+Au collisions at sqrt[s_{NN}]=200 GeV collected by the STAR experiment at the Relativistic Heavy Ion Collider. The Λ_{c}/D^{0} [denoting (Λ_{c}^{+}+Λ_{c}^{-})/(D^{0}+D[over ¯]^{0})] yield ratio is measured to be 1.08±0.16 (stat)±0.26 (sys) in the 0%-20% most central Au+Au collisions for the transverse momentum (p_{T}) range 3<p_{T}<6 GeV/c. This is significantly larger than the pythia model calculations for p+p collisions. The measured Λ_{c}/D^{0} ratio, as a function of p_{T} and collision centrality, is comparable to the baryon-to-meson ratios for light and strange hadrons in Au+Au collisions. Model calculations including coalescence hadronization for charmed baryon and meson formation reproduce the features of our measured Λ_{c}/D^{0} ratio.

Abstract
Objective: To compare the histologic features of immune-mediated hepatitis (IMH) due to immune checkpoint inhibitors (ICIs) monotherapy and combined ICIs anti-angiogenesis tyrosine kinases (TKIs) targeted therapy. Methods: Twenty-one IMH patients who had liver biopsy during ICIs treatment in Zhongshan Hospital of Fudan University from 2015 to 2019 were included. Among them, ten were treated with ICIs monotherapy, and 11 were treated with combined ICIs and anti-angiogenesis targeted therapy. The histologic features of IMH were assessed by HE staining and PD-L1/2 was evaluated by immunohistochemical staining. Results: Patients treated with monotherapy ICIs presented with different levels of lobular hepatitis and portal inflammation. Besides, there were also cholangitis, endothelialitis, Kupffer cells activation and peliosisi hepatitis. Eight cases (8/10) showed mild and two cases (2/10) showed moderate hepatic injury. As for patients receiving combined ICIs and TKIs therapy, the extent of IMH was more severe, with four cases (4/11) showing moderate-severe liver injury, with confluent or bridging necrosis, portal inflammation, cholangitis, interface hepatitis. Among these, one patient developed acute severe hepatitis with massive hepatocyte necrosis and died of multisystem dysfunction. In those cases with severe liver injury, many CD8 positive lymphocytes aggregated in the portal area and hepatic sinusoid, and PD-L1 was expressed in many endothelial cells. There were both 2 cases of death in ICIs monotherapy and combination therapy group. Among the latter group, 1 patient developed acute severe hepatitis with massive hepatocyte necrosis and died of multisystem dysfunction. Conclusion: Compared with ICIs monotherapy, combined ICIs and anti-angiogenesis targeted TKIs therapy may cause overlapping hepatic injury, leading to severe IMH.
