In this task, you're given a paragraph and title from the research paper. Your task is to classify whether the given title is suitable or not for the research paper based on the given paragraph. Return "True" if title is proper according to paragraph else "False".

[Q]: Paragraph: Experimental studies were conducted to evaluate two species of cotton rats, Sigmodon hispidus and Sigmodon fulviventer, as a model for severe acute respiratory syndrome (SARS). Blood and turbinate wash samples, and lung tissue were collected from each animal at different time points after SARS coronavirus (CoV) infection for determining the growth curve of virus, if any, by the standard infectivity assay in Vero E6 cells. In addition, sections of the lung, liver, spleen, and kidney were taken and used for histology analysis. All animals were observed daily for signs of illness, and in some experiments, animals were weighed on the day when they were sacrificed. The results indicated that the cotton rat species, S. hispidus and S. fulviventer, were not a useful model for either SARS-CoV infection or disease. This observation was supported by the absence of any signs of illness, the failure to consistently demonstrate virus in the blood and tissues, and the absent of any notable histopathology. However, infected animals were capable of producing neuralizing antibodies against SARS-CoV, suggesting the seroconversion did occur. Further studies are warranted to consider other animal species in efforts to find better animal models for the evaluation of SARS-CoV vaccines and antiviral drugs. Key Words: Cotton rats-SARS-Model animal.

[Q]: Paragraph: Although coronavirus tropism is most often ascribed to receptor availability, increasing evidence suggests that for the neurotropic strains of the murine coronavirus mouse hepatitis virus (MHV), spike-receptor interactions cannot fully explain neurovirulence. The canonical MHV receptor CEACAM1a and its spike-binding site have been extensively characterized. However, CEACAM1a is poorly expressed in neurons, and the extremely neurotropic MHV strain JHM.SD infects ceacam1a S/S mice and spreads among ceacam1a S/S neurons. Two proposed alternative MHV receptors, CEACAM2 and PSG16, also fail to account for neuronal spread of JHM.SD in the absence of CEACAM1a. It has been reported that JHM.SD has an unusually labile spike protein, enabling it to perform receptor-independent spread (RIS), but it is not clear if the ability to perform RIS is fully responsible for the extremely neurovirulent phenotype. We propose that the extreme neurovirulence of JHM.SD is multifactorial and might include as yet unidentified neuron-specific spread mechanisms.

[Q]: Paragraph: RSV, PIVs, and HMPV are members of the Paramyxoviridae family. The epidemiology, clinical manifestations, and treatment of each of these viruses are discussed separately. RSV has two subtypes, A and B, with the former typically causing more severe disease. While both subtypes can simultaneously circulate during outbreaks, a few distinct genotypes of each subtype can predominate within a community. The dominant strains can also shift yearly. This shifting of viral strains, along with the waning protective immunity from natural infection, might account for frequent re-infections throughout life [38] . RSV usually causes mild and self-limited URTI in healthy older children and nonelderly adults, but certain patient populations are at risk for developing severe RSV infection, including premature or very young infants, elderly patients with comorbidities, or immunocompromised hosts [39] [40] [41] . RSV has been associated with apnea in young or preterm infants [42] and can cause severe LRTI in children including bronchiolitis, pneumonia, and acute respiratory failure [42] . Among adults infected with RSV, more than 80% are symptomatic, and lower respiratory tract signs and symptoms can occur in a quarter of the patients [43] . Signs of URTI include cough, rhinorrhea, and conjunctivitis, and compared to influenza, RSV is more frequently associated with nasal congestion, ear and sinus involvement, productive cough, and longer duration of illness [43] .
