In this task, you are given a abstract of article and corresponding title of an article. Your task is to generate label "yes" if title is right for article, otherwise generate "no".

Example Input: Abstract: Myelodysplastic syndromes are a heterogeneous group of diseases characterized by ineffective hematopoiesis and the propensity to leukemic transformation. Their pathogenesis is complex and likely depends on interplay between aberrant hematopoietic cells and their microenvironment. How niche cells play a role in disease evolution is poorly defined, but the delineation of the hematopoietic stem cell niche and the ability to interrogate its role in hematopoietic disease in animal models have furthered our insights in recent years. The data support a view in which the microenvironment can play an active role in the evolution of myelodysplasia and myeloproliferative disorders, thus providing further rationale to explore therapeutic targeting of mesenchymalhematopoietic interactions in these diseases..

Example Input: Abstract: BACKGROUND Analysis of fetal DNA in maternal plasma has recently been introduced as a new method for noninvasive prenatal diagnosis, particularly for the analysis of fetal genetic traits, which are absent from the maternal genome, e.g., RHD or Y-chromosome-specific sequences. To date, the analysis of other fetal genetic traits has been more problematic because of the overwhelming presence of maternal DNA sequences in the circulation. We examined whether different biochemical properties can be discerned between fetal and maternal circulatory DNA.
METHODS Plasma DNA was examined by agarose gel electrophoresis. The fractions of fetal and maternal DNA in size-fractionated fragments were assayed by real-time PCR. The determination of paternally and maternally inherited fetal genetic traits was examined by use of highly polymorphic chromosome-21-specific microsatellite markers.
RESULTS Size fractionation of circulatory DNA indicated that the major portion of cell-free fetal DNA had an approximate molecular size of <0.3 kb, whereas maternally derived sequences were, on average, considerably larger than 1 kb. Analysis of size-fractionated DNA (</=0.3 kb) from maternal plasma samples facilitated the ready detection of paternally and maternally inherited microsatellite markers.
CONCLUSIONS Circulatory fetal DNA can be enriched by size selection of fragment sizes less than approximately 0.3 kb. Such selection permits easier analysis of both paternally and maternally inherited DNA polymorphisms.. Title: The financial cost of doctors emigrating from sub-Saharan Africa: human capital analysis

Example Input: Abstract: A 17-year-old boy with frequent faints due to blood-injury phobia was studied. During cardiovascular reflex investigation in our syncope unit, 50 seconds of asystole were recorded. He was treated using systematic desensitization with muscular tension and cognitive techniques by the Pediatric Psychosocial Department and has not experienced syncopal events again..
