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".

[EX Q]: Paragraph: Madin Darby canine kidney (MDCK) cells were adapted to serum-free RPMI 1640 medium and used for cultivation of canine viruses. RPMI 1640 medium was supplemented with a soybean peptone, l-glutamine and antibiotics, so that the protein concentration was less than 5 g/ml (RPMI/SP medium). The resulting adapted MDCK-SP cells showed steady growth after the twenty-eighth passage in RPMI/SP medium (MDCK-SP cell culture). Canine distemper virus, canine parvovirus, canine adenoviruses and canine parainfluenza virus, which are the principal components of canine combined virus vaccines, grew in the MDCK-SP cell culture as efficiently as the parental MDCK cells cultured in the conventional Eagle's MEM containing fetal bovine serum. Consequently, the use of MDCK-SP cell culture can make current canine vaccine products much safer, of higher quality and at lower cost.

[EX Q]: Paragraph: Dengue virus (DENV) of the Flaviviridae family is a single positive-stranded RNA virus that is transmitted by Aedes aegypti and Aedes albopictus mosquitoes. The objective of this study was to investigate the use of chloroquine (CLQ) as an antiviral drug against dengue virus in monkeys. To analyze the action of the drug in vivo, nonhuman primates groups (Aotus azarai infulatus) were inoculated with a subcutaneous injection of a virulent strain of DENV-2, treated and untreated CLQ. Blood hematological, viremia, and serum biochemical values were obtained from 16 DENV-2-inoculated, treated and untreated; four received only CLQ and one mock-infected Aotus monkeys. Monkey serum samples (day 0-10 post-inoculation) were assayed by reverse transcription polymerase chain reaction and Cytometric Bead Array for determination of viremia and inflammatory cytokines, respectively. Additionally, body temperature and activity levels were determined. In the present work, CLQ was effective on replication of DENV-2 in Aotus monkeys; a time viremia reduction was observed compared with the controls. The concentration of tumor necrosis factor alpha and interferon gamma in the serum of the animals had a statistically significant reduction in the groups treated with CLQ after infection compared with the controls. A significant decrease in systemic levels of the liver enzyme aspartate aminotransferase (AST) was also observed in the animals treated with CLQ after infection compared with the controls. These results suggest that CLQ interferes in DENV-2 replication in Aotus monkeys.

[EX Q]: Paragraph: The subgenomic (sg) mRNAs of arteriviruses (order Nidovirales) form a 5-and 3-coterminal nested set with the viral genome. Their 5 common leader sequence is derived from the genomic 5-proximal region. Fusion of sg RNA leader and "body" segments involves a discontinuous transcription step. Presumably during minusstrand synthesis, the nascent RNA strand is transferred from one site in the genomic template to another, a process guided by conserved transcription-regulating sequences (TRSs) at these template sites. Subgenomic RNA species are produced in different but constant molar ratios, with the smallest RNAs usually being most abundant. Factors thought to influence sg RNA synthesis are size differences between sg RNA species, differences in sequence context between body TRSs, and the mutual influence (or competition) between strand transfer reactions occurring at different body TRSs. Using an Equine arteritis virus infectious cDNA clone, we investigated how body TRS activity affected sg RNA synthesis from neighboring body TRSs. Flanking sequences were standardized by head-to-tail insertion of several copies of an RNA7 body TRS cassette. A perfect gradient of sg RNA abundance, progressively favoring smaller RNA species, was observed. Disruption of body TRS function by mutagenesis did not have a significant effect on the activity of other TRSs. However, deletion of body TRS-containing regions enhanced synthesis of sg RNAs from upstream TRSs but not of those produced from downstream TRSs. The results of this study provide considerable support for the proposed discontinuous extension of minus-strand RNA synthesis as a crucial step in sg RNA synthesis.
