Peptides, due to their diverse and controllable properties, are used as both liquid and gas phase recognition elements for both biological and chemical targets. While it is well understood how binding of a peptide to a biomolecule can be converted into a sensing event, there is not the same mechanistic level of understanding with regard to how peptides modulate the selectivity of semiconductor/conductor-based gas sensors. Notably, a rational, mechanistic study has not yet been performed to correlate peptide properties to the sensor response for volatile organic compounds (VOCs) as a function of chemical properties.

A nanobionic VOC sensor plant is created to study VOC-mediated plant intercommunication by incorporating surface-enhanced Raman scattering (SERS) nanosensors into a living plant. This sensor allows real-time monitoring of VOC with a sensitivity down to the parts per trillion level.
View Article and Find Full Text PDFBackground: Web-based advance care planning (ACP) interventions offer a promising solution to improve ACP engagement, but none are specifically designed to meet the needs of patients with heart failure and their caregivers.
Objective: We aimed to develop and assess the usability and acceptability of a web-based ACP decision aid called "My Voice," which is tailored for patients with heart failure and their caregivers.
Methods: This study's team and advisory board codeveloped the content for both patient and caregiver modules in "My Voice.
Purpose: The integration of cardiovascular genetic (CVG) testing into clinical practice is gaining recognition, but its implementation in the Asian setting has not been widely reported. We present our experience developing a clinical CVG service and analyze its impact on patient care at our center.
Methods: In 2020, the National Heart Centre Singapore collaborated with SingHealth Duke-NUS Genomic Medicine Centre, to establish a comprehensive clinical CVG service.
Importance: Predicting undesirable outcomes following anti-VEGF initiation in macular oedema is critical for effective clinical decision-making and optimised care.
Objective: To estimate the time to undesirable events in diabetic macular oedema (DMO), central and branch vein occlusions (CRVO and BRVO) after appropriate loading doses with either ranibizumab or aflibercept and identified baseline predictors of negative outcome.
Design, Setting, Participants: A retrospective cohort study of 3277 patients (N = 2107 in DMO, N = 413 in CRVO and N = 757 in BRVO) collected over a 10-year period, in a large UK tertiary centre.
