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: The role of DNA cytosine methylation, an epigenetic regulator of chromatin structure and function, during normal and pathological brain development and aging remains unclear. Here, we examined by MethyLight PCR the DNA methylation status at 50 loci, encompassing primarily 5 CpG islands of genes related to CNS growth and development, in temporal neocortex of 125 subjects ranging in age from 17 weeks of gestation to 104 years old. Two psychiatric disease cohortsdefined by chronic neurodegeneration (Alzheimer's) or lack thereof (schizophrenia)were included. A robust and progressive rise in DNA methylation levels across the lifespan was observed for 8/50 loci (GABRA2, GAD1, HOXA1, NEUROD1, NEUROD2, PGR, STK11, SYK) typically in conjunction with declining levels of the corresponding mRNAs. Another 16 loci were defined by a sharp rise in DNA methylation levels within the first few months or years after birth. Disease-associated changes were limited to 2/50 loci in the Alzheimer's cohort, which appeared to reflect an acceleration of the age-related change in normal brain. Additionally, methylation studies on sorted nuclei provided evidence for bidirectional methylation events in cortical neurons during the transition from childhood to advanced age, as reflected by significant increases at 3, and a decrease at 1 of 10 loci. Furthermore, the DNMT3a de novo DNA methyl-transferase was expressed across all ages, including a subset of neurons residing in layers III and V of the mature cortex. Therefore, DNA methylation is dynamically regulated in the human cerebral cortex throughout the lifespan, involves differentiated neurons, and affects a substantial portion of genes predominantly by an age-related increase..

Example Input: Abstract: Nuclear lamin B1 (LMNB1) constitutes one of the major structural proteins in the lamina mesh. We silenced the expression of LMNB1 by RNA interference in the colon cancer cell line DLD-1 and showed a dramatic redistribution of H3K27me3 from the periphery to a more homogeneous nuclear dispersion. In addition, we observed telomere attrition and an increased frequency of micronuclei and nuclear blebs. By 3D-FISH analyses, we demonstrated that the volume and surface of chromosome territories were significantly larger in LMNB1-depleted cells, suggesting that LMNB1 is required to maintain chromatin condensation in interphase nuclei. These changes led to a prolonged S phase due to activation of Chk1. Finally, silencing of LMNB1 resulted in extensive changes in alternative splicing of multiple genes and in a higher number of enlarged nuclear speckles. Taken together, our results suggest a mechanistic role of the nuclear lamina in the organization of chromosome territories, maintenance of genome integrity and proper gene splicing..

Example Input: Abstract: OBJECTIVES This paper examines policy implementation gaps of user fees plus exemptions and health insurance in providing financial access to primary clinical care for children under five in Ghana.
METHODS Methods included analysis of routine data, focus group discussions, in-depth interviews, and administration of a structured questionnaire.
RESULTS Providers modified exemptions policy implementation arrangements, sometimes giving partial or no exemptions. Clients who knew or suspected exemption entitlements failed to request them because of fear of negative reactions from providers. Providers attributed their modification of implementation arrangements and negative reactions to the threat posed to the financial viability of their institutions by reimbursement uncertainty and delays. At the time of the study insurance coverage was low and frontline workers were not noticeably modifying implementation arrangements. However, the underlying goal conflicts, resource scarcity, conditions of work and relationships between frontline workers and clients that fueled the exemptions policy implementation gaps were unchanged. The potential for the health insurance policy to stumble over implementation gaps as happened with the exemptions policy therefore remained.
CONCLUSIONS Policies that do not take into account the incentives for frontline worker adherence and align them better with policy objectives may experience implementation gaps..
