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: AIMS Alcohol is believed to be an important factor behind the sharp rise in mortality during the period 1990-94 in Russia. However, the rise in the standard alcohol consumption proxy does not seem to be sufficient to explain all the increase in mortality. This study adopts a novel approach to exploring the role of the alcohol factor in the increased mortality by investigating whether the mismatch between trends in mortality and recorded alcohol consumption is due to an underestimation of the consumption increase.
DESIGN AND MEASUREMENTS First, the alcohol effect on the male accident rate was estimated using data for the period 1959-89. Next, the estimated alcohol effect and the observed accident mortality rate for the period 1990-98 were used to backcast alcohol consumption during that period. Thirdly, the backcasted alcohol series was used to predict trajectories in alcohol poisoning mortality, the homicide rate and all-cause mortality during the period 1990-98.
FINDINGS There was a markedly stronger increase in the backcasted consumption proxy than in the standard alcohol consumption proxy during the period 1990-98. There was a substantial gap between the observed mortality rates and the rates predicted from the standard alcohol consumption proxy, whereas the predictions from the backcasted alcohol proxy were much closer to the target.
CONCLUSIONS Much of the rise in Russian mortality in 1990-94 appears to have been due to the increase in population drinking, but this increase is grossly underestimated by the commonly used consumption proxy combining alcohol sales, estimation of illicit alcohol production and proportion of alcohol-positive violent deaths..

Example Input: Abstract: Prions cause transmissible spongiform encephalopathies for which no treatment exists. Prions consist of PrPSc, a misfolded and aggregated form of the cellular prion protein (PrPC). We explore the antiprion properties of luminescent conjugated polythiophenes (LCPs) that bind and stabilize ordered protein aggregates. By administering a library of structurally diverse LCPs to the brains of prion-infected mice via osmotic minipumps, we found that antiprion activity required a minimum of five thiophene rings bearing regularly spaced carboxyl side groups. Solid-state nuclear magnetic resonance analyses and molecular dynamics simulations revealed that anionic side chains interacted with complementary, regularly spaced cationic amyloid residues of model prions. These findings allowed us to extract structural rules governing the interaction between LCPs and protein aggregates, which we then used to design a new set of LCPs with optimized binding. The new set of LCPs showed robust prophylactic and therapeutic potency in prion-infected mice, with the lead compound extending survival by >80% and showing activity against both mouse and hamster prions as well as efficacy upon intraperitoneal administration into mice. These results demonstrate the feasibility of targeted chemical design of compounds that may be useful for treating diseases of aberrant protein aggregation such as prion disease..

Example Input: Abstract: -catenin (encoded by CTNNB1) is a subunit of the cell surface cadherin protein complex that acts as an intracellular signal transducer in the WNT signaling pathway; alterations in its activity have been associated with the development of hepatocellular carcinoma and other liver diseases. Other than WNT, additional signaling pathways also can converge at -catenin. -catenin also interacts with transcription factors such as T-cell factor, forkhead box protein O, and hypoxia inducible factor 1 to regulate the expression of target genes. We discuss the role of -catenin in metabolic zonation of the adult liver. -catenin also regulates the expression of genes that control metabolism of glucose, nutrients, and xenobiotics; alterations in its activity may contribute to the pathogenesis of nonalcoholic steatohepatitis. Alterations in -catenin signaling may lead to activation of hepatic stellate cells, which is required for fibrosis. Many hepatic tumors such as hepatocellular adenomas, hepatocellular cancers, and hepatoblastomas have mutations in CTNNB1 that result in constitutive activation of -catenin, so this molecule could be a therapeutic target. We discuss how alterations in -catenin activity contribute to liver disease and how these might be used in diagnosis and prognosis, as well as in the development of therapeutics..
