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: The pursuit for drugs that inhibit cyclin-dependent kinases (CDKs) has been an intense area of research for more than 15 years. The first-generation inhibitors, Flavopiridol and CY-202, are in late-stage clinical trials, but so far have demonstrated only modest activity. Several second-generation inhibitors are now in clinical trials. Future approaches to determine clinical benefit need to incorporate both the lessons learned from these early compounds and information recently obtained from the genetic analysis of CDKs in preclinical models. Here we discuss key concepts that should be considered when validating the clinical utility of CDK inhibitors in cancer therapy.. Title: CDK inhibitors in cancer therapy: what is next?

Output: yes

Input: Consider Input: Abstract: BACKGROUND Avian influenza (AI) caused by H7 AI viruses (AIVs) of both low pathogenicity (LP) and high pathogenicity (HP) are notifiable poultry diseases.
OBJECTIVES Design and validate two RealTime reverse transcriptase polymerase chain reactions (RRT PCRs) for Eurasian H7 AIV detection and pathotyping.
METHODS The H7 RRT PCRs amplified within the (i) HA2 and (ii) cleavage site CS regions of the haemagglutinin gene. Both were validated against 65 H7 AIVs, 57 non-H7 AIVs and 259 poultry swabs in comparison to M gene (AI generic) RRT PCR and virus isolation (VI). An additional 38 swabs and 20 tissue specimens extended validation against M gene RRT PCR.
RESULTS Both H7 RRT PCRs amplified all 61 Eurasian lineage H7 AIVs and none of 57 non-H7 AIVs. A total of 297 poultry swabs were used to determine diagnostic sensitivity and specificity relative to M gene RRT PCR, sensitivity was 95.4% and 64.6% for the HA2 and CS RRT PCRs respectively, and specificity 97.9% and 99.6% respectively. The H7 HA2 RRT PCR was more sensitive than VI. This was emphasized by analysis of 37 swabs from turkeys infected experimentally with HPAI H7N1 virus sampled at 24 hours post-inoculation and LPAI H7N1 chicken infections sampled at 40-64 hours. Although less sensitive, usefulness of the H7 CS RRT PCR was confirmed by the correct molecular pathotyping for all 61 Eurasian lineage H7 AIVs tested.
CONCLUSIONS The high sensitivity of H7 HA2 RRT PCR confirms its suitability for use in poultry surveillance and disease diagnosis. H7 CS RRT PCR provides an opportunity for rapid pathotyping of H7 AIVs.. Title: Survival rates of tropical and temperate passerines: a Trinidadian perspective.

Input: Consider Input: Abstract: OBJECTIVE Corin is a serine protease that converts pro-atrial natriuretic peptide (pro-ANP) to atrial natriuretic peptide (ANP), a cardiac hormone that regulates salt-water balance and blood pressure. ANP is degraded by natriuretic peptide receptor (NPR). This study was to determine if aberrant pro-ANP/corin/NPR signaling is present in maternal vascular system in preeclampsia. STUDY DESIGN Maternal venous blood was obtained from 197 pregnant women (84 normotensive, 16 complicated with chronic hypertension (CHT), 11 mild and 86 severe preeclampsia). Plasma corin and pro-ANP concentrations were measured by enzyme-linked immunosorbent assay. Maternal subcutaneous fat tissue was obtained from 12 pregnant women with cesarean section delivery (6 normotensive and 6 preeclampsia). Vascular ANP and its receptors NPR-A, NPR-B, and NPR-C expression were examined by immunostaining of paraffin embedded subcutaneous fat tissue sections.
RESULTS Corin concentrations were significantly higher in mild (2.78 0.67 ng/ml, p < .05) and severe (2.53 0.18 ng/ml, p < .01) preeclampsia than in normotensive (1.58 0.08 ng/ml) and CHT (1.55 0.20 ng/ml) groups. Pro-ANP concentrations were significantly higher in CHT (1.59 0.53 ng/ml, p < .05) and severe preeclampsia (1.42 0.24 ng/ml, p < .01) than in normotensive (0.48 0.06 ng/ml) and mild preeclampsia (0.52 0.09 ng/ml) groups. ANP and NPR-B expression was undetectable in maternal vessels from normotensive and preeclamptic pregnancies, but reduced NPR-A expression and increased NPR-C expression was found in maternal vessel endothelium in preeclampsia.
CONCLUSIONS ANP is a vasodilator and NPR-C is a clearance receptor for ANP. The finding of upregulation of NPR-C expression suggests that circulating ANP clearance or degradation is increased in preeclampsia. These results also suggest that pro-ANP/corin/NPR signaling is dominant in the vascular system in preeclampsia..
