In Burkina Faso, recent dengue outbreaks were exacerbated by Aedes aegypti mosquitoes, which have developed resistance to conventional insecticides. This study investigates the potential of Metarhizium pingshaense Met_S26, a fungus from Burkina Faso, for controlling both endophilic and exophilic Aedes mosquitoes. Traditional interventions are less effective against mosquitoes resting outdoors, and the ability of the fungus to be sexually transmitted could enhance its efficacy. Aedes mosquitoes were reared and exposed to various concentrations of Metarhizium pingshaense to assess its virulence. The fungus showed significant efficacy, with lethal times (LT80) ranging from 8.67 to 11.83 days depending on the concentration. Furthermore, bioassays demonstrated effective sexual auto-dissemination, with substantial transmission of fungal spores between infected and uninfected mosquitoes, leading to lower survival rates in uninfected mates. This study highlights Metarhizium pingshaense Met_S26 as a promising tool for controlling both indoor and outdoor Aedes populations, complementing existing vector control strategies such as the Sterile Insect Technique (SIT) and Wolbachia-based approaches. Future research should explore integrating this fungus with other control methods for a comprehensive vector management strategy. 展开更多

The current international dissemination of China’s human rights discourse predominantly adopts a“sender-oriented”model,emphasizing the output of human rights discourse by transmitters while overlooking strategy adjustments based on audience feedback.To some extent,the current approach has resulted in characteristics such as strong practical implementation but weak discourse,limited theoretical foundation,and insufficient recognition in China’s international human rights communication.Consequently,while China has achieved remarkable progress in its human rights endeavors,human rights issues remain a critical area of stigmatization by some Western countries.An“effect-oriented”mechanism for the international dissemination of China’s human rights discourse,therefore,aims to address this challenge by re-centering the audience as active participants in the communication process.By emphasizing the dual nature of human rights’international communication,this approach leverages the reflexive monitoring of initial transmitters throughout the dissemination process to finally construct a dynamic human rights discourse framework responsive to different time and space contexts.This mechanism directly confronts the diverse backgrounds of global audiences and the resulting varied interpretations of China’s human rights discourse.It advocates for dynamic evaluation of global dissemination outcomes based on audience feedback and the timely adaptation of communication strategies according to context.By doing so,it seeks to effectively advance China’s human rights communication efforts and enhance dissemination efficiency on the global scale. 展开更多

There is no effective therapy for this condition. The 5-year survival rate of patients with peritoneal dissemination is 2%, even including patients with only microscopic free cancer cells without macroscopic peritoneal nodules. The mechanism of peritoneal dissemination of GC involves several steps: detachment of cancer cells from the primary tumor, survival in the free abdominal cavity, attachment to the distant peritoneum, invasion into the subperitoneal space and proliferation with angiogenesis. These steps are not mutually exclusive, and combinations of different molecular mechanisms can occur in each process of peritoneal dissemination. A comprehensive understanding of the molecular events involved in peritoneal dissemination is important and should be systematically pursued. It is crucial to identify novel strategies for the prevention of this condition and for identification of markers of prognosis and the development of molecular-targeted therapies. In this review, we provide an overview of recently published articles addressing the molecular mechanisms of peritoneal dissemination of GC to provide an update on what is currently known in this field and to propose novel promising candidates for use in diagnosis and as therapeutic targets. 展开更多

Objective: The predictive and prognostic role of prognostic nutritional index(PNI) in gastric cancer patients with peritoneal dissemination remains unclear. This study aims to explore the role of the PNI in predicting outcomes of gastric cancer patients with peritoneal dissemination.Methods: A total of 660 patients diagnosed with gastric adenocarcinoma with peritoneal metastasis between January 2000 and April 2014 at Sun Yat-sen University Cancer Center and the Sixth Affiliated Hospital of Sun Yatsen University were retrospectively analyzed. The clinicopathologic characteristics and clinical outcomes of patients with peritoneal dissemination were analyzed.Results: Compared with PNI-high group, PNI-low group was correlated with advanced age(P=0.036), worse performance status(P0.001), higher frequency of ascites(P0.001) and higher frequency of multisite distant metastasis(P0.001). Kaplan-Meier survival curves showed that PNI-high group had a significantly longer median overall survival than PNI-low group(13.13 vs. 9.03 months, P0.001). Multivariate survival analysis revealed that Borrmann type IV(P=0.014), presence of ascites(P=0.017) and lower PNI(P=0.041) were independent poor prognostic factors, and palliative surgery(P0.001) and first-line chemotherapy(P0.001) were good prognostic factors. For patients receiving palliative surgery, the postoperative morbidity rates in the PNI-low group and PNIhigh group were 9.1% and 9.9%, respectively(P=0.797). The postoperative mortality rate was not significantly different between PNI-low and PNI-high groups(2.3% vs. 0.9%, P=0.362).Conclusions: PNI is a useful and practical tool for evaluating the nutritional status of gastric cancer patients with peritoneal dissemination, and is an independent prognostic factor for these patients. 展开更多

Mineral dissemination and pore space distribution in ore particles are important features that influence heap leaching performance.To quantify the mineral dissemination and pore space distribution of an ore particle,a cylindrical copper oxide ore sample(I center dot 4.6 mm x 5.6 mm)was scanned using high-resolution X-ray computed tomography(HRXCT),a nondestructive imaging technology,at a spatial resolution of 4.85 mu m.Combined with three-dimensional(3D)image analysis techniques,the main mineral phases and pore space were segmented and the volume fraction of each phase was calculated.In addition,the mass fraction of each mineral phase was estimated and the result was validated with that obtained using traditional techniques.Furthermore,the pore phase features,including the pore size distribution,pore surface area,pore fractal dimension,pore centerline,and the pore connectivity,were investigated quantitatively.The pore space analysis results indicate that the pore size distribution closely fits a log-normal distribution and that the pore space morphology is complicated,with a large surface area and low connectivity.This study demonstrates that the combination of HRXCT and 3D image analysis is an effective tool for acquiring 3D mineralogical and pore structural data. 展开更多

Objective:Peritoneal dissemination is difficult to diagnose by conventional imaging technologies.We aimed to construct a nomogram to predict peritoneal dissemination in gastric cancer(GC)patients.Methods:We retrospectively analyzed 1,112 GC patients in Sun Yat-sen University Cancer Center between2001 and 2010 as the development set and 474 patients from The Sixth Affiliated Hospital,Sun Yat-sen University between 2010 and 2016 as the validation set.The clinicopathological variables associated with gastric cancer with peritoneal dissemination(GCPD)were analyzed.We used logistic regression analysis to identify independent risk factors for peritoneal dissemination.Then,we constructed a nomogram for the prediction of GCPD and defined its predictive value with a receiver operating characteristic(ROC)curve.External validation was performed to validate the applicability of the nomogram.Results:In total,250 patients were histologically identified as having peritoneal dissemination.Logistic regression analysis demonstrated that age,sex,tumor location,tumor size,signet-ring cell carcinoma(SRCC),T stage,N stage and Borrmann classification IV(Borrmann IV)were independent risk factors for peritoneal dissemination.We constructed a nomogram consisting of these eight factors to predict GCPD and found an optimistic predictive capability,with a C-index of 0.791,an area under the curve(AUC)of 0.791,and a 95%confidence interval(95%CI)of 0.762-0.820.The results found in the external validation set were also promising.Conclusions:We constructed a highly sensitive nomogram that can assist clinicians in the early diagnosis of GCPD and serve as a reference for optimizing clinical management strategies. 展开更多

Objective: To identify independent prognostic factors to be included in a nomogram to predict the prognosis ofgastric cancer patients with peritoneal dissemination.Methods: This is a retrospective study on 684 patients with a histological diagnosis of gastric cancer withperitoneal dissemination from the Sun Yat-sen University Cancer Center as the development set, and 62 gastriccancer patients from the Sixth Affiliated Hospital of Sun Yat-sen University as the validation group. Chi-square testand Cox regression analysis were used to compare the clinicopathological variables and the prognosis of gastriccancer patients with peritoneal dissemination. The Harrell's concordance index (C-index) and calibration curvewere determined for comparisons of predictive ability of the nomogram.Results: Univariate and multivariate analyses showed that serum carcinoembryonic antigen (CEA) level(P=0.032), ascites grading (P=0.008), presence of extraperitoneal metastasis (P〈0.001), seeding status (P=0.016) andperformance status (P=0.009) were independent prognostic factors for gastric cancer patients with peritonealdissemination in the development set. The nomogram model was constructed using these five factors. Internalvalidation showed that the C-index of the model was 0.641. For the external validation, the C-index of this modelwas 0.709.Conclusions: We developed and validated a nomogram to predict the prognosis for gastric cancer patients withperitoneal dissemination. This nomogram may play an important clinical role in guiding palliative therapy for thesetypes of patients, although it may need more data for optimization. 展开更多

In opportunistic networks, most existing buffer management policies including scheduling and passive dropping policies are mainly for routing protocols. In this paper, we proposed a Utility-based Buffer Management strategy(UBM) for data dissemination in opportunistic networks. In UBM, we first design a method of computing the utility values of caching messages according to the interest of nodes and the delivery probability of messages, and then propose an overall buffer management policy based on the utility. UBM driven by receivers completely implements not only caching policies, passive and proactive dropping policies, but also scheduling policies of senders. Simulation results show that, compared with some classical dropping strategies, UBM can obtain higher delivery ratio and lower delay latency by using smaller network cost. 展开更多
