Phylogenomic conflict coincides with rapid morphological innovation.

Proceedings of the National Academy of Sciences of the United States of America

Parins-Fukuchi C, Stull GW, Smith SA.
PMID: 33941696
Proc Natl Acad Sci U S A. 2021 May 11;118(19). doi: 10.1073/pnas.2023058118.

Evolutionary biologists have long been fascinated with the episodes of rapid phenotypic innovation that underlie the emergence of major lineages. Although our understanding of the environmental and ecological contexts of such episodes has steadily increased, it has remained unclear...

Journal for nurses in professional development

Smith TA, Perez JK, Friesen MA.
PMID: 33935191
J Nurses Prof Dev. 2021 Apr 28; doi: 10.1097/NND.0000000000000750. Epub 2021 Apr 28.

Focus groups are a standard method of qualitative data collection and an excellent method for data collection in nursing professional development. Advances in technology, virtual health care, and the COVID-19 pandemic increase the opportunities to use virtual focus groups...

Transplanting hepatitis C viremic donor organs into hepatitis C virus (HCV)-negative recipients is becoming increasingly common; however, practices for posttransplant direct-acting antiviral (DAA) treatment vary widely. Protracted insurance authorization processes for DAA therapy often lead to treatment delays.METHODS: At...

Exposure to cumulative stressors affects the laying phenology and incubation behaviour of an Arctic-breeding marine bird.

The Science of the total environment

Smith RA, Albonaimi SS, Hennin HL, Gilchrist HG, Fort J, Parkinson KJL, Provencher JF, Love OP.

Wildlife are exposed to multiple stressors across life-history stages, the effects of which can be amplified as human activity surges globally. In Arctic regions, increasing air and ocean temperatures, more severe weather systems, and exposure to environmental contaminants all...

Longitudinal increases in childhood depression symptoms during the COVID-19 lockdown.

Archives of disease in childhood

Bignardi G, Dalmaijer ES, Anwyl-Irvine AL, Smith TA, Siugzdaite R, Uh S, Astle DE.

Arch Dis Child. 2020 Dec 09; doi: 10.1136/archdischild-2020-320372. Epub 2020 Dec 09.

OBJECTIVE: There has been widespread concern that so-called lockdown measures, including social distancing and school closures, could negatively impact children's mental health. However, there has been little direct evidence of any association due to the paucity of longitudinal studies...

Reactions of a series of phenyl esters with a (PNP)Rh fragment have been studied. PhO(2)CPh only underwent C-H oxidative addition (OA). PhO(2)CCF(3) chiefly underwent acyl-oxygen OA. PhO(2)CBu(t) and PhO(2)CNEt(2) initially underwent OA of an ortho-C-H bond of the phenyl...
