Phenotypic and transcriptomic acclimation of the green microalga Raphidocelis subcapitata to high environmental levels of the herbicide diflufenican.

Herbicide pollution poses a worldwide threat to plants and freshwater ecosystems. However, the understanding of how organisms develop tolerance to these chemicals and the associated trade-off expenses are largely unknown. This study aims to investigate the physiological and transcriptional mechanisms underlying the acclimation of the green microalgal model species Raphidocelis subcapitata (Selenastraceae) towards the herbicide diflufenican, and the fitness costs associated with tolerance development.

Ileo-rectal anastomosis in ulcerative colitis-Long-term outcome, failure and risk of cancer at a tertiary centre.

Aim: Ileo-rectal anastomosis (IRA) is an option to restore bowel continuity after colectomy in patients with ulcerative colitis (UC). Concerns that the remaining rectum may serve as a site for continuing proctitis with subsequent poor function and IRA failure and the fear of development of dysplasia and cancer have led to the abandonment of IRA in large parts of the world. This study investigated the outcome of IRA in a large patient cohort with UC and IRA with regard to failure of IRA and development of dysplasia and cancer.

Ileal pouch-anal anastomosis; 18 years of experience and outcomes across two generations of surgeons at a tertiary center in Sweden.

Aim: Reconstructive surgery with ileal pouch-anal anastomosis (IPAA) is the standard procedure after colectomy in patients with Ulcerative Colitis (UC) and Familial Adenomatous Polyposis (FAP). It is of interest to understand how a generation shift of the surgeons performing IPAA has affected patients' outcomes.

Method: All consecutive patients who underwent IPAA in the period 1999-2016 at Sahlgrenska University Hospital/Östra, Gothenburg, Sweden, were included.

Expanding Family Medicine Scholarship to All Faculty: The Minnesota Model for Harmonizing Clinical Care, Education, and Research Missions.

Background: The Department of Family Medicine and Community Health at the University of Minnesota engaged in a 5-year transformation to expand research and scholarship opportunities to all faculty. A harmonization framework was used to integrate the 3 missions of clinical care, education, and research to ensure that research and scholarship were an ongoing focus of the department.

Methods: The key elements of our transformation included as follows: (1) a general culture of inquiry, (2) harmonized leadership, (3) training and mentoring, and (4) infrastructure and resources.

Tracking of marine predators to protect Southern Ocean ecosystems.

Southern Ocean ecosystems are under pressure from resource exploitation and climate change. Mitigation requires the identification and protection of Areas of Ecological Significance (AESs), which have so far not been determined at the ocean-basin scale. Here, using assemblage-level tracking of marine predators, we identify AESs for this globally important region and assess current threats and protection levels.
