Methane emissions from forested closed landfill sites: Variations between tree species and landfill management practices.

Trees in natural and managed environments can act as conduits for the transportation of methane (CH) from below ground to the atmosphere, bypassing oxidation in aerobic surface soils. Tree stem emissions from landfill sites exhibit large temporal and spatial variability in temperate environments and can account for approximately 40% of the total surface CH flux. Emission variability was further investigated in this study by measuring CH and CO fluxes from landfill sites with different management strategies and varying tree species over a 7-month period.

Methane emissions from trees planted on a closed landfill site.

Trees have morphological adaptations that allow methane (CH) generated below ground to bypass oxidation in aerobic surface soils. This natural phenomenon however has not been measured in a landfill context where planted trees may alter the composition and magnitude of CH fluxes from the surface. To address this research gap, we measured tree stem and soil greenhouse gas (GHG) emissions (CH and CO) from a closed UK landfill and comparable natural site, using an off-axis integrated cavity output spectroscopy analyser and flux chambers.

Preferential human epidermal growth factor receptor 2 expression in myometrial and lymphovascular invasion of a uterine carcinosarcoma: A case report.

This case report describes a unique pattern of human epidermal growth factor receptor 2 expression in a patient with uterine carcinosarcoma. The endometrial tumor showed biphasic morphology composed of serous carcinoma and a heterologous high-grade sarcoma component. Human epidermal growth factor receptor 2 immunostaining showed positive (3+) expression in foci of myoinvasion, lymphovascular invasion, and lymph node metastasis but was negative in both the endometrial surface tumor and sarcomatous component.

Disseminated Tele-OSCE During a Pandemic: One University's Experience.

Background: Due to coronavirus disease 2019 (COVID-19), in-person educational activities were suspended across the globe throughout 2020. In health care education, this required a swift, creative response to maintain the flow of trained clinicians into the workforce without compromising the integrity of core learning outcomes. Early during the pandemic, remote synchronous simulation emerged as a compelling focus of the overall strategy.

The Tele-STELLA protocol: Telehealth-based support for families living with later-stage Alzheimer's disease.

Aims: We aim to establish the feasibility and acceptability of the Tele-STELLA (Support via Telehealth: Living and Learning with Advancing Alzheimer's Disease and Related Dementias) intervention. We will also assess the efficacy of the intervention in reducing the frequency of behavioural symptoms of dementia as well as family Care Partner reactivity to the symptoms.

Design: This is a multi-component, quasi-experimental study that focuses on facilitating effective management of behavioural symptoms that occur in the later stages of dementia.
