This dual amplification process is characterized by a low limit of detection (LOD) of 3.04 aM. In addition, the electrochemical biosensor exhibits good selectivity for miR-21 detection, and shows benefits of simple operation, low cost, portability. Overall, the electrochemical biosensor provides a promising platform for the early diagnosis and screening of tumor biomarkers and the development of devices for point-of-care testing (POCT).Children attach to objects for many reasons. Early research on object attachment focused primarily on infants and toddlers and their attachment to soft objects as a source of security, but this review reveals that children of all ages attach to a variety of objects and with a variety of motivations. This review also introduces the concept of transitory object attachments, in which children quickly attach to an object but un-attach almost as quickly. Repeated transitory object attachments are manifest as materialism. After a discussion of motivations for object attachment generally, the review focuses on the insecurities of childhood that can foster transitory object attachments and materialism in children. Managing persistent epistaxis poses a great challenge for the otolaryngologist. Despite continuous development in treatment methods, no universal guideline has been commonly adopted. Among the popular methods is endoscopic sphenopalatine artery ligation (ESPAL). This study aims to evaluate the impact of ESPAL integration on persistent epistaxis management over 15years in a single academic center. A retrospective study including all cases who were hospitalized due to persistent epistaxis and required intervention between 2000 and 2016. From 2011, ESPAL was routinely utilized in our center, hence the study population was divided based o
