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.

Let me give you an example: The severe acute respiratory syndrome (SARS) epidemic originating from China in 2002 was caused by a previously uncharacterized coronavirus that could be identified by specific RT-PCR amplification. Efforts to control future SARS outbreaks depend on the accurate and early identification of SARS-CoV infected patients. A real-time fluorogenic RT-PCR assay based on the 3 -noncoding region (3 -NCR) of SARS-CoV genome was developed as a quantitative SARS diagnostic tool. The ideal amplification efficiency of a sensitive SARS-CoV RT-PCR assay should yield an E value (PCR product concentration increase per amplification cycle) equal to 2.0. It was demonstrated that the 3 -NCR SARS-CoV based RT-PCR reactions could be formulated to reach excellent E values of 1.81, or 91% amplification efficacy. The SARS-CoV cDNA preparations derived from viral RNA extract and the cloned recombinant plasmid both exhibit the identical amplification characteristics, i.e. amplification efficacy using the same PCR formulation developed in this study. The viral genomic copy (or genomic equivalences, GE) per infectious unit (GE/pfu) of SARS-CoV used in this study was also established to be approximate 1200-1600:1. The assay's detection sensitivity could reach 0.005 pfu or 6-8 GE per assay. It was preliminarily demonstrated that the assay could efficiently detect SARS-CoV from clinical specimens of SARS probable and suspected patients identified in Taiwan. The 3 -NCR based SARS-CoV assay demonstrated 100% diagnostic specificity testing samples of patients with acute respiratory disease from a non-SARS epidemic region.
The answer to this example can be: Development and evaluation of an efficient 3 -noncoding region-based SARS coronavirus (SARS-CoV) RT-PCR assay for detection of SARS-CoV
Here is why: It's a correct title because the paragraph described the development of 3 -noncoding region of SARS-CoV genome and assay efficiently detecting SARS-CoV from clinical specimens.

The rat (Rattus norvegicus) is used in a broad field of biomedical research, and numerous animal models for human diseases have been developed. The rat genetic map, however, remains poorly documented. Hedrich (1990) described a rat linkage map consisting of 13 groups, of which only 6 were assigned to chromosomes. Levan and coworkers (1991, 1992) collected mapping information from the literature, including their own works. Their tables and figures contain gene chromosomal assignments, cytogenetical localizations, and comparisons of the rat G-banding pattern with those of mice and humans, but do not include any information about gene orders or distances. Recently, an informative rat genetic linkage map has been reported by Serikawa and colleagues (1992b). It is based on the segregation of 125 polymorphic markers in seven rat backcrosses and two F 2 crosses, and all of the linkage groups are assigned to particular chromosomes. The linkage map and the information on microsatellite markers became a great help for genetic studies with rat models for human diseases. Since then, a considerable amount of new data for the rat linkage map has appeared in several publications. We, therefore, have collected mapping data published up to the middle of 1993, including our recent reports, and have summarized it here in a list of mapped loci. This genetic map, constructed by combining several linkage data, and two comparative maps for mouse or human homologous rat genes should be very informative to many researchers working on genetic studies in rats, mice, or humans.
