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".

[EX Q]: Abstract: Injection drug users (IDUs) are at increased risk for HIV, viral hepatitis, and tuberculosis, and making up more than a quarter of the incarcerated population in the United States. Methadone maintenance treatment of opiate addiction is highly effective at reducing drug use, drug-related criminal activity, and risk of HIV transmission. Recently released inmates are at particularly high risk for overdose and disease transmission. Linkage to methadone treatment immediately upon release from incarceration is a promising opportunity to combat disease transmission, facilitate reentry into the community, and reduce recidivism..

[EX Q]: Abstract: The proteasome is a major cytosolic proteolytic assembly, essential for the physiology of eukaryotic cells. Both the architecture and enzymatic properties of the 20S proteasome are relatively well understood. However, despite longstanding interest, the integration of structural and functional properties of the proteasome into a coherent model explaining the mechanism of its enzymatic actions has been difficult. Recently, we used tapping mode atomic force microscopy (AFM) in liquid to demonstrate that the alpha-rings of the proteasome imaged in a top-view position repeatedly switched between their open and closed conformations, apparently to control access to the central channel. Here, we show with AFM that the molecules in a side-view position acquired two stable conformations. The overall shapes of the 20S particles were classified as either barrel-like or cylinder-like. The relative abundance of the two conformers depended on the nature of their interactions with ligands. Similarly to the closed molecules in top view, the barrels predominated in control or inhibited molecules. The cylinders and open molecules prevailed when the proteasome was observed in the presence of peptide substrates. Based on these data, we developed the two-state model of allosteric transitions to explain the dynamics of proteasomal structure. This model helps to better understand the observed properties of the 20S molecule, and sets foundations for further studies of the structural dynamics of the proteasome..

[EX Q]: Abstract: Aims The gut microbiome influences metabolic syndrome (MetS) and inflammation and is therapeutically modifiable. Arterial stiffness is poorly correlated with most traditional risk factors. Our aim was to examine whether gut microbial composition is associated with arterial stiffness. Methods and results We assessed the correlation between carotid-femoral pulse wave velocity (PWV), a measure of arterial stiffness, and gut microbiome composition in 617 middle-aged women from the TwinsUK cohort with concurrent serum metabolomics data. Pulse wave velocity was negatively correlated with gut microbiome alpha diversity (Shannon index, Beta(SE)= -0.25(0.07), P = 1 10-4) after adjustment for covariates. We identified seven operational taxonomic units associated with PWV after adjusting for covariates and multiple testing-two belonging to the Ruminococcaceae family. Associations between microbe abundances, microbe diversity, and PWV remained significant after adjustment for levels of gut-derived metabolites (indolepropionate, trimethylamine oxide, and phenylacetylglutamine). We linearly combined the PWV-associated gut microbiome-derived variables and found that microbiome factors explained 8.3% (95% confidence interval 4.3-12.4%) of the variance in PWV. A formal mediation analysis revealed that only a small proportion (5.51%) of the total effect of the gut microbiome on PWV was mediated by insulin resistance and visceral fat, c-reactive protein, and cardiovascular risk factors after adjusting for age, body mass index, and mean arterial pressure. Conclusions Gut microbiome diversity is inversely associated with arterial stiffness in women. The effect of gut microbiome composition on PWV is only minimally mediated by MetS. This first human observation linking the gut microbiome to arterial stiffness suggests that targeting the microbiome may be a way to treat arterial ageing..
