In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.

[Q]: Many examples of the emergence or re-emergence of infectious diseases involve the adaptation of zoonotic viruses to new amplification hosts or to humans themselves. These include several instances of simple mutational adaptations, often to hosts closely related to the natural reservoirs. However, based on theoretical grounds, arthropod-borne viruses, or arboviruses, may face several challenges for adaptation to new hosts. Here, we review recent findings regarding adaptive evolution of arboviruses and its impact on disease emergence. We focus on the zoonotic alphaviruses Venezuelan equine encephalitis and chikungunya viruses, which have undergone adaptive evolution that mediated recent outbreaks of disease, as well as the flaviviruses dengue and West Nile viruses, which have emerged via less dramatic adaptive mechanisms.

[Q]: The requirement for negative pressure isolation procedures has been an accepted component of pediatric care to protect patients and staff from highly infectious respiratory agents. Surveys regarding airborne isolation were distributed to 43 pediatric emergency departments at US children's hospitals with 26 responses. There was a median of 5 airborne isolation rooms, a median of 4 of those with negative pressure, and 61% without an ante-room. Capacity to manage pediatric patients infected with a highly pathogenic airborne-transmitted organism during an epidemic is limited.

[Q]: 20 This work aimed to evaluate the cytotoxic potential against cancer cells of Passiflora genus 21 plant species cultivated in Brazil and identify the mechanism of cytotoxicity induced by the 22 most promising extract. Leaf extracts from 14 Passiflora (P.) species were obtained ASE and 23 in vitro cytotoxicity evaluated against cancer cell lines using MTT assay at a single .

Additionally, the IC 50 of the P. alata (ELPA) leaf extracts was 25 determined against both tumor (HCT-116, SF-295, OVACAR-8, and HL-60), and non-tumor 26 cells (PBMC). The ELPA flavonoids were identified by HPLC-DAD and UHPLC-MS/MS. 27 The morphological analyses used light and fluorescence microscopy, and cell cycle and DNA 28 fragmentation analyses used flow cytometry to determine the mechanism of cell death induced 29 by ELPA in HL-60. Among the Passiflora leaf extracts evaluated; ELPA stood out with high 30 cytotoxic activity, followed by P. capsularis and P. quadrangulares with varying high and low 31 cytotoxic activity. ELPA presented high cytotoxic potency in HL-60 (IC 50 19.37 g/mL), yet 32 without cytotoxic activity against PBMC, suggesting selectivity for tumor cells. The cytotoxic 33 activity of ELPA may well be linked to the presence of ten identified flavonoids. Cells treated 34 with ELPA presented the hallmarks typical of apoptosis and necrosis, with cell cycle arrest in 35 the G2/M phase. Conclusion: From among the studied species, ELPA presented greater 36 cytotoxic activity, possibly a consequence of synergistic flavonoid action which induces cell 37 death by apoptosis and necrosis.
