Keeping schools open during the emergence of the COVID-19 alpha variant: Impact on the circulation of SARS-CoV-2 among children during the 2020-2021 school year: Epidemiology of COVID-19 in children and adolescents during the 2020-2021 school year in France.

Background: During 2020-2021, in the context of increasing SARS-CoV-2 transmission in the general population, French authorities made the decision to keep schools open and set up massive screening campaigns for students. Here, we describe the impact of this strategy on the circulation of SARS-COV-2 among children and adolescents during this period.

Methods: We analyzed SARS-COV-2 surveillance data provided by the French National Public Health Agency for the 2020-2021 school year along with the results of school-based screening campaigns implemented by the Ministry of National Education.

Long-term consequences of positive surgical margin after partial nephrectomy for renal cell carcinoma: multi-institutional analysis.

Introduction: The aim of the study was to determine the impact of positive surgical margins (PSM) after PN on very long-term recurrence in a contemporary cohort.

Methods: Patients who underwent PN for a localized renal tumour were included. Patients were stratified according to the presence of PSM.

Coevolutionary analysis of Pseudomonas syringae-phage interactions to help with rational design of phage treatments.

Treating plant bacterial diseases is notoriously difficult because of the lack of available antimicrobials. Pseudomonas syringae pathovar syringae (Pss) is a major pathogen of cherry (Prunus avium) causing bacterial canker of the stem, leaf and fruit, impacting productivity and leading to a loss of trees. In an attempt to find a treatment for this disease, naturally occurring bacteriophage (phage) that specifically target Pss is being investigated as a biocontrol strategy.

Genetic dissection of the tissue-specific roles of type III effectors and phytotoxins in the pathogenicity of Pseudomonas syringae pv. syringae to cherry.

When compared with other phylogroups (PGs) of the Pseudomonas syringae species complex, P. syringae pv. syringae (Pss) strains within PG2 have a reduced repertoire of type III effectors (T3Es) but produce several phytotoxins.
