Reward-based Crowdfunding Success Prediction with Multimodal Data
As an increasing number of crowdfunding platforms recommend that entrepreneurs post multimodal data to improve data diversity and attract investors’ attention, it becomes necessary to study how functions of multimodal data take effect to predict fundraising outcomes (i.e., success or failure). There is a lack of research providing a comprehensive investigation of multimodal data in crowdfunding. Rooted in language and visual image metafunctional theories, we propose a framework to explore ideational, interpersonal, and textual metafunctions of multimodal data. We empirically examine the effectiveness of each metafunction, each modality, and their combination in predicting fundraising outcomes. The empirical evaluation shows the predictive utility of any metafunctions and metafunction combinations. The results also demonstrate that adding data modalities can help to improve the prediction performance
Proteomic Dissection of Cell Type-Specific H2AX-Interacting Protein Complex Associated with Hepatocellular Carcinoma
The replacement histone variant H2AX senses DNA double-strand breaks (DSBs) and recruits characteristic sets of proteins at its phosphorylated (γ-H2AX) foci for concurrent DNA repair. We reasoned that the H2AX interaction network, or interactome formed in the tumor-associated DNA DSB environment such as in hepatocellular carcinoma (HCC) cells, where pre-neoplastic lesions frequently occur, is indicative of HCC pathogenic status. By using an in vivo dual-tagging quantitative proteomic method, we identified 102 H2AX-specific interacting partners in HCC cells that stably expressed FLAG-tagged H2AX at close to the endogenous level. Using bioinformatics tools for data-dependent network analysis, we further found binary relationships among these interactors in defined pathway modules, implicating H2AX in a multi-functional role of coordinating a variety of biological pathways involved in DNA damage recognition and DNA repair, apoptosis, nucleic acid metabolism, Ca2+-binding signaling, cell cycle, etc. Furthermore our observations suggest that these pathways interconnect through key pathway components or H2AX interactors. The physiological accuracy of our quantitative proteomic approach in determining H2AX-specific interactors was evaluated by both co-immunoprecipitation/ immunoblotting and confocal co-localization experiments performed on HCC cells. Due to their involvement in diverse functions, the H2AX interactors involved in different pathway modules, such as Poly(ADP-ribose) polymerase1, 14-3-3ζ, coflin1, and peflin1, were examined for their relative H2AX binding affinities in paired hepatocytes and HCC cells. Treatment with the DSB-inducing agent bleomycin enhanced binding of these proteins to H2AX, suggesting an active role of H2AX in coordinating the functional pathways of each protein in DNA damage recognition and repair
Mature cystic extragonadal teratoma in Douglas’ pouch: Case report and literature review
Teratomas often occur in the gonads, while Extragonadal mature cystic teratomas are reported occasionally, with the most common site being the omentum. Teratoma in the Douglas sac is extremely rare. we report a rare case of mature cystic Teratoma in the Douglas sac in a 71-year-old woman who underwent laparoscopic surgery. A cyst with a diameter of approximately 6 cm from Douglas was found during surgery, and the mass was separated from both ovaries. Microscopically, the cyst was a mature cystic teratoma that did not originate from the ovary
Simultaneous radical cystectomy and nephroureterectomy in the treatment of panurothelial carcinoma: a systematic review and single-arm meta-analysis
BackgroundPanurothelial carcinoma is a rare and aggressive malignancy that requires effective treatment strategies to enhance patient outcomes.MethodsWe conducted a systematic search of English publications in databases including PubMed, Embase, Cochrane Library, and Web of Science up to May 2023. The quality of the literature was assessed using the Newcastle-Ottawa Scale (NOS) and the Methodological Quality and Synthesis of Case Series and Case Reports tool. Data statistics and analysis were performed using Stata 15.1 software (StataSE, USA).ResultsSix studies involving 339 patients were included in the analysis. Meta-analysis revealed that Simultaneous Radical Cystectomy and Nephroureterectomy had 2-year and 5-year overall survival rates of 68% (95% CI 60%-76%, I2 = 12.4%, P < 0.001) and 44% (95% CI 36%-53%, I2 = 0, P < 0.001), respectively. The 2-year and 5-year progression-free survival rates were 91% (95% CI 86%-95%, I2 = 95%, P < 0.001) and 65% (95% CI 58%-73%, I2 = 91.5%, P < 0.001), respectively. The 2-year and 5-year cancer-specific survival rates were 73% (95% CI 66%-81%, I2 = 16.7%, P < 0.001) and 57% (95% CI 49%-66%, I2 = 0, P < 0.001), respectively. Additionally, the incidence of minor complications was 19% (95% CI 15%-23%, P < 0.01), major complications was 49% (95% CI 34%-63%, P < 0.01), and the intraoperative blood transfusion rate was 53% (95% CI 44%-61%, P < 0.01).ConclusionsSimultaneous radical cystectomy and nephroureterectomy represent feasible approaches for the treatment of Panurothelial carcinoma. Nonetheless, a comprehensive assessment of the surgical risks and benefits is imperative, and larger-scale prospective cohort studies are required to validate therapeutic efficacy.

Two ultraviolet radiation datasets that cover China
Ultraviolet (UV) radiation has significant effects on ecosystems, environments, and human health, as well as atmospheric processes and climate change. Two ultraviolet radiation datasets are described in this paper. One contains hourly observations of UV radiation measured at 40 Chinese Ecosystem Research Network stations from 2005 to 2015. CUV3 broadband radiometers were used to observe the UV radiation, with an accuracy of 5%, which meets the World Meteorology Organization's measurement standards. The extremum method was used to control the quality of the measured datasets. The other dataset contains daily cumulative UV radiation estimates that were calculated using an all-sky estimation model combined with a hybrid model. The reconstructed daily UV radiation data span from 1961 to 2014. The mean absolute bias error and root-mean-square error are smaller than 30% at most stations, and most of the mean bias error values are negative, which indicates underestimation of the UV radiation intensity. These datasets can improve our basic knowledge of the spatial and temporal variations in UV radiation. Additionally, these datasets can be used in studies of potential ozone formation and atmospheric oxidation, as well as simulations of ecological processes

Interaction between PHB2 and Enterovirus A71 VP1 Induces Autophagy and Affects EV-A71 Infection
Enterovirus A71 (EV-A71) is a major pathogen that causes severe and fatal cases of hand-foot-and-mouth disease (HFMD). HFMD caused by EV-A71 seriously endangers children’s health. Although autophagy is an important antiviral defense mechanism, some viruses have evolved strategies to utilize autophagy to promote self-replication. EV-A71 can utilize autophagy vesicles as replication scaffolds, indicating that EV-A71 infection is closely related to its autophagy induction mechanism. VP1, a structural protein of EV-A71, has been reported to induce autophagy, but the underlying mechanism is still unclear. In this study, we found that the C-terminus (aa 251–297) of VP1 induces autophagy. Mass spectrometry analysis suggested that prohibitin 2 (PHB2) interacts with the C-terminus of the EV-A71 VP1 protein, and this was further verified by coimmunoprecipitation assays. After PHB2 knockdown, EV-A71 replication, viral particle release, and viral protein synthesis were reduced, and autophagy was inhibited. The results suggest that PHB2 interaction with VP1 is essential for induction of autophagy and the infectivity of EV-A71. Furthermore, we confirmed that EV-A71 induced complete autophagy that required autolysosomal acidification, thus affecting EV-A71 infection. In summary, this study revealed that the host protein PHB2 is involved in an autophagy mechanism during EV-A71 infection
