文摘Accurately forecasting the triple point(TP)path is essential for analyzing blast loads and assessing the destructive effectiveness of the height of burst explosion.Empirical models that describe the TP path under normal temperature and pressure environments are commonly employed;however,in certain configurations,such as at high-altitudes(HAs),the environment may involve low temperature and pressure conditions.The present study develops a theoretical prediction model for the TP path under reduced pressure and temperature conditions,utilizing the image bursts method,reflected polar analysis,and dimensional analysis.The model's accuracy is evaluated through numerical simulations and experimental data.Results indicate that the prediction model effectively evaluates the TP path under diminished temperature and pressure conditions,with most predictions falling within a±15%deviation.It was found that the TP height increases with altitude.As the altitude rises from 0 m to 10,000 m,the average TP height increases by 61.7%,87.9%,109.0%,and 134.3%for the scaled height of burst of 1.5 m,2.0 m,2.5 m,and 3.0 m,respectively.Moreover,the variation in TP height under HA environments closely mirrors that observed under corresponding reduced pressure conditions.In HA environments,only the effect of low-pressure conditions on the TP path needs to be considered,as the environmental lowtemperature has a minimal effect.
文摘BACKGROUND Standard triple therapy is an effective treatment for eradicating Helicobacter pylori infection,but it is encountered with drug resistance.The stool antigen test is a cost-effective and easy-to-perform test to confirm the eradication of H.pylori,4-8 weeks post-therapy,with 86%sensitivity and 92%specificity.AIM To assess the H.pylori eradication rate of standard triple therapy and factors affecting the eradication rate.METHODS We conducted a prospective,multicenter follow-up study in Addis Ababa,Ethiopia,at selected healthcare facilities among dyspeptic patients with positive stool H.pylori antigen tests from June 1,2023 to October 30,2023 to assess the H.pylori eradication rate.After completing the standard triple therapy,the eradication was confirmed using a stool antigen test 4 weeks later.The data were analyzed using bivariate and multivariate logistic regression methods.RESULTS The H.pylori eradication rate was 85.4%.Patients with a previous diagnosis of H.pylori infection,smokers,and local alcohol consumption were associated with a lower H.pylori eradication rate,with adjusted odds ratio(AORs)of 0.159[95%confidence interval(CI):0.050-0.511],0.206(95%CI:0.052-0.822),and 0.228(95%CI:0.052-0.997),respectively.Patients with complete symptom resolution were 5.383 times more likely to achieve eradication than patients without symptom improvement,AOR=5.383,95%CI:1.74-21.089.CONCLUSION H.pylori eradication rate was lower than expected.Post-treatment testing is crucial to confirm eradication and guide further management,such as susceptibility testing.
文摘BACKGROUND Patients with gastric cancer may have a risk of depression after radical surgery,which affects recovery and requires intensive intervention.AIM To explore the role of Bifidobacterium triple viable bacteria-assisted mirtazapine in patients with depression after radical surgery for gastric cancer.METHODS This study included 80 patients with gastric cancer who experienced depression after undergoing radical surgery from January 2022 to December 2023 at Jiangnan University Hospital in Wuxi city in Jiangsu province.The patients were categorized into the control group(n=40)treated with mirtazapine and observation group(n=40)treated with combined Bifidobacterium triple viable bacteria-assisted mirtazapine.Neuroendocrine index,intestinal flora level,nutrition status,and patient quality of life were analyzed.RESULTS Before drug index level,no statistically significant difference was observed between the two groups (P>0.05).After drug administration,both groups experienced a decline in depression scores,cortisol,Escherichia coli,Enterococcus faecalis levels,and quality of life scores,whereas dopamine,serotonin,Lactobacillus,Bifidobacteria,hemoglobin,serum albumin and prealbumin levels increased.The observation group demonstrated significantly greater improvements across these indicators,with significant differences within groups and between groups(P<0.05).CONCLUSION Bifidobacterium has a relieving effect on depression in patients after radical surgery for gastric cancer,improves neuroendocrine status,regulates intestinal flora,and improves nutritional status and quality of life.

文摘Discoidin domain receptor 1(DDR1)is overexpressed in various tumors,such as triple-negative breast cancer(TNBC),and is rarely expressed in normal tissues.These characteristics make DDR1 a preferable target candidate for the construction of an antibody-drug conjugate(ADC)for targeted therapy.Here,we investigated the preparation and preclinical efficacy of DDR1-DX8951,an ADC that includes an anti-DDR1 monoclonal antibody conjugated to DX8951 by a cleavable Gly-Gly-Phe-Gly(GGFG)linker.The anti-DDR1 monoclonal antibody was coupled to DX8951(i.e.,DDR1-DX8951),producing the targeted therapy ADC.The antitumor activities of DDR1-DX8951 monotherapy or DDR1-DX8951 plus pembrolizumab were assessed in TNBC mouse models.DDR1-DX8951 can specifically target DDR1,be quickly internalized by TNBC cells,and reduce the viability of TNBC cells in vitro.The potent antitumor activity of DDR1-DX8951 was revealed in TNBC xenograft models.Importantly,our investigation demonstrated that DDR1-DX8951 plus pembrolizumab not only revealed the inhibitory efficacy on tumor growth and metastasis but also played an important role in improving the immunosuppressive tumor microenvironment(TME)of TNBC.Taken together,this investigation provides justification for large-sample studies to further assess the safety and efficacy of DDR1-DX8951 plus pembrolizumab for TNBC clinical trials.

文摘Promoting the high penetration of renewable energies like photovoltaic(PV)systems has become an urgent issue for expanding modern power grids and has accomplished several challenges compared to existing distribution grids.This study measures the effectiveness of the Puma optimizer(PO)algorithm in parameter estimation of PSC(perovskite solar cells)dynamic models with hysteresis consideration considering the electric field effects on operation.The models used in this study will incorporate hysteresis effects to capture the time-dependent behavior of PSCs accurately.The PO optimizes the proposed modified triple diode model(TDM)with a variable voltage capacitor and resistances(VVCARs)considering the hysteresis behavior.The suggested PO algorithm contrasts with other wellknown optimizers from the literature to demonstrate its superiority.The results emphasize that the PO realizes a lower RMSE(Root mean square errors),which proves its capability and efficacy in parameter extraction for the models.The statistical results emphasize the efficiency and supremacy of the proposed PO compared to the other well-known competing optimizers.The convergence rates show good,fast,and stable convergence rates with lower RMSE via PO compared to the other five competitive optimizers.Moreover,the lowermean realized via the PO optimizer is illustrated by the box plot for all optimizers.
