Abdominal Ultrasound Assists the Diagnosis and Management of Necrotizing Enterocolitis.

Background: Abdominal x-ray (KUB) routinely aids in detecting necrotizing enterocolitis (NEC), one of the most serious neonatal intestinal diseases. However, a KUB may miss up to 50% of the early signs of NEC. Recent advances in abdominal ultrasound (AUS) can expedite this diagnosis and improve clinical management.

The revised Approved Instructional Resources score: An improved quality evaluation tool for online educational resources.

Background: Free Open-Access Medical education (FOAM) use among residents continues to rise. However, it often lacks quality assurance processes and residents receive little guidance on quality assessment. The Academic Life in Emergency Medicine Approved Instructional Resources tool (AAT) was created for FOAM appraisal by and for expert educators and has demonstrated validity in this context.

Molecular characterization of two lactate dehydrogenase genes with a novel structural organization on the genome of Lactobacillus sp. strain MONT4.

Two lactate dehydrogenase (ldh) genes from Lactobacillus sp. strain MONT4 were cloned by complementation in Escherichia coli DC1368 (ldh pfl) and were sequenced. The sequence analysis revealed a novel genomic organization of the ldh genes.
