Metabolomics and Transcriptomics Reveal the Response Mechanisms of to Infection.

is one of the worst invasive species globally and can cause significant negative impacts on agricultural and forestry economics, particularly in Asia and the Pacific region. The rust has been used successfully as a biological control agent in several countries to help manage . However, the response mechanisms of to infection have never been studied.

Global Actions for Managing Cactus Invasions.

The family Cactaceae Juss. contains some of the most widespread and damaging invasive alien plant species in the world, with Australia (39 species), South Africa (35) and Spain (24) being the main hotspots of invasion. The Global Cactus Working Group (IOBC GCWG) was launched in 2015 to improve international collaboration and identify key actions that can be taken to limit the impacts caused by cactus invasions worldwide.

Characteristics of children hospitalized with infective endocarditis.

Background: Infective endocarditis in children is rare, and most reports describe the experience in referral centers. The purpose of our study was to assess the characteristics of children with infective endocarditis in a large national sample.

Methods And Results: We analyzed hospital discharge records with International Classification of Diseases, ninth revision, codes indicating infective endocarditis among admissions of patients <21 years of age in the Kids' Inpatient Databases 2000 and 2003; analyses for the 2 years were combined.

Skip metastasis in osteosarcoma.
