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.

Ex Input:
ARTICLES We synthesized three overlapping 19-amino-acid peptides spanning the F binding domain of RhoA (amino acids 67-110) and used these to study the effect of peptides on virus-induced syncytium formation. Pretreatment of virus inoculum with the RhoA 77-95 peptide completely blocked plaque formation, whereas pretreatment with RhoA 87-105 did not have any effect on the plaque formation relative to media-treated controls (Fig. 1) . The RhoA 67-85 peptide did not block RSV-induced syncytium forma- by reduction of peak titer by 2 log 10 in RSV-infected mice. These findings indicate that the interaction between these two paramyxovirus fusion proteins and RhoA is an important target for new antiviral strategies.

Ex Output:
A RhoA-derived peptide inhibits syncytium formation induced by respiratory syncytial virus and parainfluenza virus type 3

Quinone-methide triterpenes, celastrol (1), pristimerin (2), tingenone (3), and iguesterin (4) were isolated from Triterygium regelii and dihydrocelastrol (5) was synthesized by hydrogenation under palladium catalyst. Isolated quinone-methide triterpenes (1-4) and 5 were evaluated for SARS-CoV 3CL pro inhibitory activities and showed potent inhibitory activities with IC 50 values of 10.3, 5.5, 9.9, and 2.6 lM, respectively, whereas the corresponding 5 having phenol moiety was observed in low activity (IC 50 = 21.7 lM). As a result, quinone-methide moiety in A-ring and more hydrophobic E-ring assist to exhibit potent activity. Also, all quinone-methide triterpenes 1-4 have proven to be competitive by the kinetic analysis.

Ex Output:
SARS-CoV 3CL pro inhibitory effects of quinone-methide triterpenes from Tripterygium regelii

Ex Input:
Severe acute respiratory syndrome -associated coronavirus (SARS-CoV) was introduced to the United States through air travel. Although the risk of SARS-CoV transmission within aircraft cabins has been addressed by several studies, the magnitude of the risk remains unclear. Methods. We attempted to contact all persons with working US telephone numbers aboard seven US-bound fl ights carrying SARS patients. Consenting participants responded to a questionnaire, and a serum sample was collected at least 38 days after the fl ight and tested for SARS-CoV-associated antibodies. Participants reporting an illness compatible with SARS, with onset during the 2-to 10-day incubation period, were considered suspect cases; positive serology was required for confi rmed cases. Results. Among 1,766 passengers and crew, 339 (19%) persons were contacted. Of these, 312 (92%) completed questionnaires, and blood was collected from 127 (37%). Serology was negative for all 127 participants, including three of four who met the clinical case criteria for SARS, and the fourth had a mild illness that lasted only 5 days. Conclusions. Transmission of SARS-associated CoV was not observed, suggesting that the risk of transmission is not amplifi ed aboard aircraft.
