Example Input: Dendritic cells (DC)-derived or tumor-derived exosomes are a population of nanometer sized membrane vesicles that can induce specific anti-tumor immunity. However, the immunogenic potential and efficiency of exosomes-based tumor vaccine are not satisfactory enough to achieve a curative effect in clinical trials. In this article we investigated whether IL-18 genetic modification of tumor cells can increase the efficacy of exosomes derived from IL-18 gene-modified tumor cells. We transfected carcinoembryonic antigen (CEA)-expressing tumor cells with a recombinant adenovirus encoding human IL-18 (AdhIL-18) and prepared the exosomes, Exo/IL-18, from IL-18 gene-modified tumor cells. We found that Exo/IL-18 naturally contain CEA and bioactive IL-18. Moreover, Exo-IL-18 are potent in chemoattracting DC and T cells, enhancing the proliferation and Th1 cytokine release of PBMC, and promoting the phenotypic and functional maturation of DC. Furthermore, Exo/IL-18-pulsed DC are quite potent to induce HLA-A*0201-restricted, CEA-specific CD8 + CTL from the PBMC of HLA-A*0201 CEA + cancer patients in vitro. In almost all of these experiments, Exo/IL-18 show more potent functions than the conventionally prepared exosomes derived from parent tumor cells without IL-18 gene modification. Our findings suggest that Exo/IL-18 has more potent capability to induce specific anti-tumor immunity, and our strategy of IL-18 modification of exosomes is a feasible approach to develop exosomesbased tumor vaccines.
Example Output: Enhanced induction of dendritic cell maturation and HLA-A*0201-restricted CEA-specific CD8 + CTL response by exosomes derived from IL-18 gene-modified CEA-positive tumor cells

Example Input: In this paper, a modified susceptible infected susceptible (SIS) epidemic model is proposed on community structure networks considering birth and death of node. For the existence of node's death would change the topology of global network, the characteristic of network with death rate is discussed. Then we study the epidemiology behavior based on the mean-field theory and derive the relationships between epidemic threshold and other parameters, such as modularity coefficient, birth rate and death rates (caused by disease or other reasons). In addition, the stability of endemic equilibrium is analyzed. Theoretical analysis and simulations show that the epidemic threshold increases with the increase of two kinds of death rates, while it decreases with the increase of the modularity coefficient and network size.

Example Input: Background: Molecular assays for diagnosis of Flu A, Flu B, and RSV with short turn-around-time (TAT) are of considerable clinical importance. In addition, rapid and accurate diagnosis of a large panel of viral and atypical pathogens can be crucial in immunocompromised patients. Objectives: First, to evaluate the performance of the Simplexa™️ Direct assay system in comparison with direct fluorescent antibody (DFA) and customized Taqman®️ Array Card (TAC) testing for RSV, Flu A, and Flu B in immunocompromised patients. Second, to evaluate different algorithms for the detection of respiratory pathogens in terms of cost, turn-around-time (TAT) and diagnostic yield. Study design: We collected 125 nasopharyngeal swabs (NTS) and 25 BAL samples from symptomatic immunocompromised patients. Samples for which Simplexa™️ and TAC results were discordant underwent verification testing. The TAC assay is based on singleplex RT-PCR, targeting 24 viruses, 8 bacteria and 2 fungi simultaneously. Results: The overall sensitivity was significantly lower for DFA testing than for the two molecular methods (p < 0.05). Performance characteristics of Simplexa™️ testing were not significantly different compared to TAC testing (p > 0.1). For BAL samples only, the sensitivity and specificity of the Simplexa™️ assay was 100%. In total, 6.7, 16 and 18% of samples were positive for Flu A, Flu B or RSV by DFA, Simplexa™️ and TAC testing, respectively. When considering not only these pathogens but also all results for TAC, the method identified 93 samples with one or more respiratory pathogens (62%). A co-infection rate of 15.3% was found by TAC. The estimated costs and TAT were 8.2 and 2 h for DFA, 31.8 and 1.5 h for Simplexa™️ and 55 and 3 h for TAC testing. Conclusions: Performing the Simplexa™️ test 24 h a day/7 days a week instead of DFA would considerably improve the overall sensitivity and time-to-result, albeit at a higher cost generated in the laboratory. Performing the TAC would increase the diagnostic yield and detection of co-infections significantly.
