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".

Input: Consider Input: Abstract: Telomerase is a ribonucleoprotein enzyme complex that reverse-transcribes an integral RNA template to add short DNA repeats to the 3'-ends of telomeres. G-quadruplex structure in a DNA substrate can block its extension by telomerase. We have found that hnRNP A1--which was previously implicated in telomere length regulation--binds to both single-stranded and structured human telomeric repeats, and in the latter case, it disrupts their higher-order structure. Using an in vitro telomerase assay, we observed that depletion of hnRNP A/B proteins from 293 human embryonic kidney cell extracts dramatically reduced telomerase activity, which was fully recovered upon addition of purified recombinant hnRNP A1. This finding suggests that hnRNP A1 functions as an auxiliary, if not essential, factor of telomerase holoenzyme. We further show, using chromatin immunoprecipitation, that hnRNP A1 associates with human telomeres in vivo. We propose that hnRNP A1 stimulates telomere elongation through unwinding of a G-quadruplex or G-G hairpin structure formed at each translocation step.. Title: hnRNP A1 associates with telomere ends and stimulates telomerase activity.

Input: Consider Input: Abstract: OBJECTIVES To investigate the views of parents, clinicians, and children pertaining to prescribing decisions for acute childhood infection in primary care.
METHODS A systematic review of qualitative studies. Meta-ethnographic methods were used, with data drawn from the primary studies in an interpretive analysis.
RESULTS A total of 15 studies met the inclusion criteria. The literature was dominated by concerns about antibiotic over-prescription. Children's views were not reported. Clinicians prescribed antibiotics when they felt pressured by parents or others (e.g. employers) to do so, when they believed there was a clear clinical indication, but also when they felt uncertain of clinical or social outcomes they prescribed "just in case". Parents wanted antibiotics when they felt they would improve the current illness, and when they felt pressure from daycare providers or employers. Clinicians avoided antibiotics when they were concerned about adverse reactions or drug resistance, when certain they were not indicated, and when there was no perceived pressure from parents. Parents also wished to avoid adverse effects of antibiotics, and did not want antibiotics when they would not relieve current symptoms. Some parents preferred to avoid medication altogether. Within paediatric consultations, parents sought a medical evaluation and decision. Primary care clinicians want satisfied parents and short consultations.
CONCLUSIONS Antibiotic prescriptions for childhood infections in primary care often result from "just in case" prescribing. These findings suggest that interventions which reduce clinician uncertainty regarding social or clinical outcomes and provide strategies to meet parents' needs within a short consultation are most likely to reduce antibiotic prescribing..

Input: Consider Input: Abstract: The object of this study was to assess the role of brown adipose tissue (BAT) and the sympathetic nervous system in the rise in heat production associated with endotoxin-induced fever. Oxygen consumption (VO2) was found to be significantly increased (28%) over a 4-h period after two doses of endotoxin (Escherichia coli lipopolysaccharide, 0.3 mg/100 g body wt) given 24 h apart. Injection of a mixed beta-adrenoceptor antagonist (propranolol) reduced VO2 by 14% in endotoxin-treated rats, whereas the selective beta 1- (atenolol) or beta 2- (ICI 118551) antagonists suppressed VO2 by 10%. These drugs did not affect VO2 in control animals. BAT thermogenic activity assessed from measurements of in vitro mitochondrial guanosine 5'-diphosphate (GDP) binding was elevated by 54% in interscapular BAT and by 171% in other BAT depots. Surgical denervation of one lobe of the interscapular depot prevented these responses. Endotoxin failed to stimulate GDP binding in rats fed protein-deficient diets. This may have been because BAT thermogenic activity was already elevated in control rats fed these diets or because endotoxin caused a marked suppression of food intake in the protein-deficient animals. The results indicate that sympathetic activation of BAT is involved in the thermogenic responses to endotoxin and that these can be modified by dietary manipulation..
