Fine-Scale Genetic Structure of Small Fish Populations in Islands: The Case of Brook Charr (Mitchill, 1814) in Saint-Pierre and Miquelon (France).

Island ecosystems, particularly vulnerable to environmental challenges, host many endangered native species. Diadromous fish, in particular, are threatened throughout their marine and freshwater habitats. The conservation of these species requires an in-depth understanding of their genetic diversity and structure, to better understand their adaptive potential.

Evaluating the impact of COVID-19 protection measures and staff absence on radiotherapy practice: A simulation study.

Background: Radiotherapy practice for cancer treatment is resource-intensive and demands optimised processes for patient throughput while guaranteeing the quality and safety of the therapy. With the COVID-19 pandemic, ad-hoc changes in the operation of radiotherapy centres became necessary to protect patients and staff. This simulation study aimed to quantify the impact of designated COVID-19 protection measures and pandemic-related staff absence on patient waiting times and throughput.

Burnout and Professional Quality of Life Assessment in Portuguese Healthcare Professionals Working in Oncology and Palliative Care: A Cross-Sectional Study.

Introduction/background: Burnout is a three-dimensional syndrome characterized by exhaustion that appears when the professional is constantly exposed to a stressful work environment, as well as depersonalization and lower personal accomplishment. Professional quality of life at work can be defined as the satisfaction degree that a person feels when being or going to their workplace.

Objective: To evaluate burnout and professional quality of life in healthcare professionals working in oncology and palliative care.

Double-faced diffusive gradient in thin films sampler (df-DGT): Proposing an improved DGT sampler design for water deployments.

Background: The Diffusive Gradients in Thin Films (DGT) technique has become the most widely used passive sampling method for inorganic compounds. This widespread adoption can be partly attributed to the development of new binding phases that facilitate the sampling of numerous analytes. In contrast, to date, the DGT sampler for inorganic compounds has not seen any significant design improvements.

Dietary nitrate supplementation very slightly mitigates the oxidative stress induced by high-intensity training performed in normobaric hypoxia.

Oxidative stress is augmented under hypoxic environments, which may be attenuated with antioxidant supplementation. We investigated the effects of dietary nitrate (NO-) supplementation combined with high-intensity training performed under hypoxic conditions on antioxidant/pro-oxidant balance. Thirty trained participants were assigned to one of three groups - HNO: hypoxia (13% FO) + NO-; HPL: hypoxia + placebo; CON: normoxia (20.
