Background: Data on the readiness of the general emergency departments (EDs) in Canada to care for children requiring emergency care are limited. Recent evidence suggests an inverse association between pediatric readiness of the general ED and mortality.
Objectives: To assess the baseline pediatric readiness of the general EDs in the province of Manitoba, Canada, to care for acutely ill and injured children.
Little is understood about the unintended consequences of cannabis liberalization on children. Subsequently, this scoping review aimed to map and identify evidence related to acute cannabis intoxication in children. We searched three medical literature databases from inception until October 2019.

Mutant p53 induces enhanced tumour metastasis in mice, and human cells overexpressing p53R273H have aberrant polarity and increased invasiveness, demonstrating the 'gain of function' of mutant p53 in carcinogenesis. We hypothesize that p53R273H interacts with mutant p53-specific binding partners that control polarity, migration or invasion.

The DENV-2 positive-strand RNA genome contains 5' and 3' untranslated regions (UTRs) that have been shown to form secondary structures required for virus replication and interaction with host cell proteins. In order to comprehensively identify host cell factors that bind the DENV-2 UTRs, we performed RNA chromatography, using the DENV-2 5' and 3' UTRs as "bait", combined with quantitative mass spectrometry.

Though the tumor suppressive function involves the lipid phosphatase-dependent and -independent activities of PTEN, the mechanism leading to the phosphatase-independent function of PTEN is understood poorly. Some PTEN mutants have lipid phosphatase activity but fail to suppress cell growth.
