External Testing of a Commercial AI Algorithm for Breast Cancer Detection at Screening Mammography.

Purpose To test a commercial artificial intelligence (AI) system for breast cancer detection at the BC Cancer Breast Screening Program. Materials and Methods In this retrospective study of 136,700 women (age: µ = 58.8, σ = 9.

Sphingobacterium gobiense sp. nov., isolated from soil of the Gobi Desert.

A Gram-stain-negative, short rod-shaped, non-motile, non-spore-forming bacterial strain, designated H7(T), was isolated from the Gobi desert, Xinjiang Province of China. The temperature, NaCl and pH ranges for growth were 8-40 °C (optimum 30 °C), 0-5 % (w/v) NaCl and pH 6-10 (optimum pH 7), respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain H7(T) belonged to the genus Sphingobacterium and showed highest sequence similarity (91 %) to Sphingobacterium composti DSM 18850.

Genome-wide investigation and functional characterization of the beta-ketoadipate pathway in the nitrogen-fixing and root-associated bacterium Pseudomonas stutzeri A1501.

Background: Soil microorganisms are mainly responsible for the complete mineralization of aromatic compounds that usually originate from plant products or environmental pollutants. In many cases, structurally diverse aromatic compounds can be converted to a small number of structurally simpler intermediates, which are metabolized to tricarboxylic acid intermediates via the beta-ketoadipate pathway. This strategy provides great metabolic flexibility and contributes to increased adaptation of bacteria to their environment.
