When Fleeing Matters:Differences in Escape Behaviours of Three Northeast Asian Anurans

Prey species may have their own optimal escape strategy to balance predation risks and the energetic cost of fleeing.Some species have an advantage when maintaining a short fleeing distance,while others may favour an earlier escape based on microhabitat,size,or body condition.Here,we examined the escape behaviour of the three syntopic Northeast Asian anuran species:Mongolian toads(Strauchbufo raddei),Amur brown frogs(Rana amurensis),and Japanese treefrogs(Dryophytes japonicus)in Mongolia,Russia,China and DPR Korea.We examined flight initiation distance(FID;the distance from a potential predator to the point when the individual starts to flee)and distance fled(DF;distance between flight initiation and flight termination points)of each species and the effects of microhabitat,sex,and body size.Strauchbufo raddei and R.amurensis had a longer FID than D.japonicus,and S.raddei also had a longer DF than D.japonicus.These trends remained similar when dividing FID and DF by a size proxy(snout-vent length)for all individuals.This suggests that the treefrog D.japonicus used a strategy to stay immobile even when they were detected,and the toad S.raddei reacted quicker and more sensitively to predators despite the presence of toxin.Female S.raddei had a significantly longer FID than males suggesting that females are more sensitive to predation risk in this species,but body size was not significant for any of the three species.Our results indicate that the three sympatric species have different escaping strategies,likely related to differences in physiology and crypticity.

Possible mechanisms associated with immune escape and apoptosis on anti-hepatocellular carcinoma effect of Mu Ji Fang granules

BACKGROUND Hepatocellular carcinoma(HCC)is one of the most common digestive system cancers with high mortality rates worldwide.The main ingredients in Mu Ji Fang Granules(MJF)are alkaloids,flavonoids,and polysaccharides.MJF has been used in the clinical treatment of hepatitis,cirrhosis and HCC for more than 30 years.Few previous studies have focused on the mechanism of MJF on tumor immunology in the treatment of HCC.AIM To explore the mechanism of action of MJF on tumor immunology in the treatment of HCC.METHODS The absorbable ingredients of MJF were identified using Molecule Network related to High Performance Liquid Chromatography-Electron Spray Ionization-Time of Flight-Mass Spectrometry,and hub potential anti-HCC targets were screened using network pharmacology and pathway enrichment analysis.Forty male mice were randomly divided into the Blank,Model,and MJF groups(1.8,5.4,and 10.8 g/kg/d)following 7 d of oral administration.Average body weight gain,spleen and thymus indices were calculated,tumor tissues were stained with hematoxylin and eosin,and Interferon gamma(IFN-γ),Tumor necrosis factorα(TNF-α),Interleukin-2,aspartate aminotransferase,alanine aminotransferase,alpha-fetoprotein(AFP),Fas,and FasL were measured by Enzyme-linked Immunosorbent Assay.Relevant mRNA expression of Bax and Bcl2 was evaluated by Real Time Quantitative PCR(RTqPCR)and protein expression of Transforming growth factorβ1(TGF-β1)and Mothers against decapentaplegic homolog(SMAD)4 was assessed by Western blotting.The HepG2 cell line was treated with 10 mg/mL,20 mg/mL,30 mg/mL,40 mg/mL of MJF,and another 3 groups were treated with TGF-β1 inhibitor(LY364947)and different doses of MJF.Relevant mRNA expression of TNF-α,IFN-γ,Bax and Bcl2 was evaluated by RT-qPCR and protein expression of TGF-β1,SMAD2,p-SMAD2,SMAD4,and SMAD7 was assessed by Western blotting.RESULTS It was shown that MJF improved body weight gain and tumor inhibition rate in H22 tumorbearing mice,protected immune organs and liver function,reduced the HCC indicator AFP,affected immunity and apoptosis,and up-regulated the TGF-β1/SMAD signaling pathway,by increasing the relative expression of TGF-β1,SMAD2,p-SMAD2 and SMAD4 and decreasing SMAD7,reducing immune factors TNF-αand IFN-γ,decreasing apoptosis cytokines Fas,FasL and Bcl2/Bax,and inhibiting the effect of LY364947 in HepG2 cells.CONCLUSION MJF inhibits HCC by activating the TGF-β1/SMAD signaling pathway,and affecting immune and apoptotic cytokines,which may be due to MJF adjusting immune escape and apoptosis.

Noise color influence on escape times in nonlinear oscillators-experimental and numerical results

The interplay between noise and nonlinearites can lead to escape dynamics.Associated nonlinear phe-nomena have been observed in various applications ranging from climatology to biology and engineering.For reasons of computational ease,in most studies,Gaussian white noise is used.However,this noise model is not physical due to the associated infinite energy content.Here,the authors present extensive experimental investigations and numerical simulations conducted to examine the impact of noise color on escape times in nonlinear oscillators.With a careful parameterization of the numerical simulations,the authors are able to make quantitative comparisons with experimental results.Through the experi-ments and simulations,it is illustrated that the noise color can drastically influence escape times and escape probability.

Secondary electron emission and photoemission from a negative electron affinity semiconductor with large mean escape depth of excited electrons

The formulae for parameters of a negative electron affinity semiconductor(NEAS)with large mean escape depth of secondary electrons A(NEASLD)are deduced.The methods for obtaining parameters such asλ,B,E_(pom)and the maximumδandδat 100.0 keV≥E_(po)≥1.0 keV of a NEASLD with the deduced formulae are presented(B is the probability that an internal secondary electron escapes into the vacuum upon reaching the emission surface of the emitter,δis the secondary electron yield,E_(po)is the incident energy of primary electrons and E_(pom)is the E_(po)corresponding to the maximumδ).The parameters obtained here are analyzed,and it can be concluded that several parameters of NEASLDs obtained by the methods presented here agree with those obtained by other authors.The relation between the secondary electron emission and photoemission from a NEAS with large mean escape depth of excited electrons is investigated,and it is concluded that the presented method of obtaining A is more accurate than that of obtaining the corresponding parameter for a NEAS with largeλ_(ph)(λ_(ph)being the mean escape depth of photoelectrons),and that the presented method of calculating B at E_(po)>10.0 keV is more widely applicable for obtaining the corresponding parameters for a NEAS with largeλ_(ph).

Meta-Analysis of the Effect of the Escape Room Teaching Method on Nursing Education

Objectives:A meta-analysis was conducted to systematically evaluate the effect of the escape room teaching method on nursing education.Methods:We searched PubMed,Medline,Web of Science,CNKI,VIP,and Wanfang databases,with a search time frame from the first day of database establishment to October 2022.Two researchers evaluated the quality of the obtained literature and extracted the data.The RevMan5.4 software was used for meta-analysis.Results:A total of 7 studies involving 1487 nursing students were included.Compared with the control group,the escape room teaching method improved the professional performance of nursing students[standardized mean difference(SMD)=0.98,95%confidence interval(CI;0.38,1.59),P<0.0001].The critical thinking ability of nursing students was enhanced[mean difference(MD)=12.64,95%CI(7.91,17.37),P<0.0001],and the investment level of nursing students in learning was improved[MD=4.18,95%CI(1.74,6.62),P<0.0001].Conclusion:The escape room teaching method can improve nursing students’professional performance,critical thinking ability,and learning engagement level.There is no significant difference in the impact of nursing teaching satisfaction,and there is still a lack of data support.This paper is limited by the quality and quantity of included literature,and more high-quality studies are still needed to further demonstrate the above conclusions.

Alpha-fetoprotein triggers hepatoma cells escaping from immune surveillance through altering the expression of Fas/FasL and tumor necrosis factor related apoptosis-inducing ligand and its receptor of lymphocytes and liver cancer cells

AIM: To investigate the mechanism of α-fetoprotein (AFP)in escaping from the host immune surveillance of hepatocellular carcinoma.METHODS: AFP purified from human umbilical blood was administrated into the cultured human lymphoma Jurkat T cell line or hepatoma cell line, Bel7402 in vitro. The expression of tumor necrosis factor related apoptosisinducing ligand (TRAIL) and its receptor (TRAILR) mRNA were analyzed by Northern blot and Western blot wasused to detect the expression of Fas and Fas ligand (FasL)protein.RESULTS: AFP (20 mg/L) could promote the expression of FasL and TRAIL, and inhibit the expression of Fas and TRAILR of Bel7402 cells. For Jurkat cell line, AFP could suppress the expression of FasL and TRAIL, and stimulate the expression of Fas and TRAILR. AFP also could synergize with Bel7402 cells to inhibit the expression of FasL protein and TRAIL mRNA in Jurkat cells. The monoclonal antibody against AFP (anti-AFP) could abolish these functions of AFP.CONCLUSION: AFP is able to promote the expression of FasL and TRAIL in hepatoma cells and enhance the expression of Fas and TRAILR in lymphocytes. These could elicit the escape of hepatocellular carcinoma cells from the host's lymphocytes immune surveillance.

Escape from the Besieged Fortress——An Analysis of Alice Munro's "Runaway"

Alice Munro is one of the famous Canadian writers and is renowned above all for the astonishing subtlety of her short stories.Her theme has often been the dilemmas of the female coming to terms with family, friends in a small town. This paper attempts to make a brief introduction about the stories of Alice Munro's Runaway and explores the protagonist's choices in the dilemma situation, and then exposes the cruelty of reality is that they cannot get rid of the ineluctable reality of life. Escape is only a temporary action which cannot save them from endless triviality of life. What they should do is not to escape from life, but to adapt to the reality of life.

Costimulatory Molecule B7-H1 on the Immune Escape of Bladder Cancer and Its Clinical Significance

B7-H1, a recently described member of the B7 family of costimulatory molecules, is thought to be involved in tumor immune escape by inducing T-cell apoptosis. In order to investigate the relationship between B7-H1 and immune escape of bladder cancer, B7-H1 expression in 50 cases of bladder cancer was detected by using immunohistochemical method. Survival curves were con- structed using the Kaplan-Meier method and independent prognostic factors were evaluated using the Cox regression model. Our results showed that the positive rate of B7-H1 immunostaining in normal bladder tissue and bladder cancer was 0 and 72% respectively. The expression of B7-H1 was strongly associated with the pathological grade, clinical stage and recurrence （P〈0.05）. The survival rate was significantly lower in patients with B7-H1 positive group than in those with B7-H1 negative group and multi-variable analysis revealed that B7-H1 could be regarded as an independent factor in evaluating the prognosis of bladder cancer. It is concluded that the expression of B7-H1 is strongly associated with neoplastic progression and prognosis of bladder cancer. The manipulation of B7-H1 may become a beneficial target for immunotherapy in human bladder cancer.

A Case of Hepatitis B Reactivation due to the Hepatitis B Virus Escape Mutant in a Patient undergoing Chemotherapy

A 62-year-old man had chronic hepatitis B virus （HBV） infection and was diagnosed with liver cirrhosis. At the time of diagnosis the patient＇s virologic markers were positive for hepatitis B surface antigen （HBsAg）, antibody to hepatitis B e antigen （anti-HBe） and antibody to hepatitis B core antigen （anti-HBc）, while antibody to hepatitis B surface antigen （anti-HBs） and HBV DNA were negative. Later the patient received chemotherapy for malignancy. However, this was interrupted due to elevated liver enzymes. At the same time HBV DNA became positive. Lamivudine （LMV） therapy was administered immediately. However, the levels of serum aminotransferase and total bilirubin （TB） were still rising. Finally the patient died of fulminant hepatic failure. A sequence revealed HBV genotype C （HBsAg subtype adw） with immune escape mutations, F8L, $34L, F41S, G44V, F93C, V96G, Lll0I, C149Y and F161Y. The high morbidity and mortality of this complication is one of the major obstacles to completing the standard treatment for malignancy in HBV carriers. Therefore, the relative risk of antiviral prophylactic failure should be further assessed and the optimal strategy for antiviral prophylaxis in HBsAg-positive patients with oncologic and hematologic malignancies undergoing chemotherapy should be revised.

Single-cell RNA-seq reveals the immune escape and drug resistance mechanisms of mantle cell lymphoma

Objective:Mantle cell lymphoma(MCL)is a rare subtype of non-Hodgkin lymphoma(NHL)with high heterogeneity and a high recurrence rate.How heterogenous cell populations contribute to relapse remains to be elucidated.Methods:We performed single cell RNA sequencing(scRNA-seq)on approximately 4,000 bone marrow cells sampled from one patient with multidrug resistant MCL.We identified 10 subpopulations comprising 4 malignant B cell subtypes,3 T cell subtypes,2 dendritic cell subtypes and 1 natural killer(NK)cell subtype.Subsequently,we identified cell markers,including a series of genes associated with immune escape and drug resistance.In addition,we explored the roles of these genes in the mechanism of immune escape and drug resistance,and we verified the expression imbalance and clinical prognostic potential by using GEO datasets including 211 MCL samples.Results:The major immune escape mechanisms of MCL included anti-perforin activity,decreased immunogenicity and direct inhibition of apoptosis and cell killing,as mediated by type I and II B cells.The drug resistance mechanisms of different cell clusters included drug metabolism,DNA damage repair,apoptosis and survival promotion.Type III B cells closely communicate with other cells.The key genes involved in the resistance mechanisms showed dysregulated expression and may have significant clinical prognostic value.Conclusion:This study investigated potential immune escape and drug resistance mechanisms in MCL.The results may guide individualized treatment and promote the development of therapeutic drugs.
