Venous leg ulcers have impact on people's lives far beyond that of a skin lesion but these impacts have not been explored from an Indigenous perspective. We used a Māori-centered narrative approach to interview 13 Māori in Aotearoa New Zealand with venous leg ulcers. Data analysis was informed by a reflexive thematic approach and four themes were identified: Ko waewae ahau (I wear the leg); Ngā mea hōhā (annoying things); Ka tangi te ngākau (heartfelt grief); and Mamae (pain, sore, hurt).

- A deep understanding of carbon cycling in soil-plant systems is crucial for creating accurate models that predict how global carbon reserves respond to human activities.
- Honey, rich in carbon and produced by pollinators, reflects the interactions of millions of plants and insects, and our study of 121 U.S. honey samples reveals the presence of older carbon affected by these interactions.
- We found that some honey samples contained carbon values significantly above expected atmospheric levels, suggesting that sources like soil carbon or plant sugars contributed to this older carbon, shifting sample ages and indicating a new method for tracing carbon in ecosystems.
Trees and shrubs maintain carbon reserves to support their functions during periods when metabolic demand exceeds carbon supply, such as during the dormant season. To gain a better understanding of carbon storage and utilisation dynamics of eight woody plant species in temperate Central Europe, bud scale and leaf samples were collected to determine the radiocarbon age of fresh sprouts in trees and shrubs, at three background sites avoiding local emissions that may influence affect the observed C/C ratio. The accelerator mass spectrometry-based bomb-radiocarbon approach, to determine the age of the mobilized carbon in the plant bud samples from storage, was complemented by stable carbon isotope measurements.

Method: This was a secondary analysis of a cohort of four randomised controlled trials (RCTs) of treatments adjuvant to compression. Self-reported ulcer duration, and measured ulcer length and width, to calculate estimated ulcer area, were used to obtain a Margolis index score.
