Site-selective -arylations of glycoside-derived diols have been achieved by couplings with bromoarenes upon irradiation with blue LEDs in the presence of an iridium photocatalyst and a nickel complex. The use of hexamethylenetetramine (hexamine) in place of quinuclidine, along with the application of a methoxy-substituted 2,2'-bipyridine ligand, provided improvements in yield for this relatively challenging substrate class. Selective arylation took place at the less sterically hindered OH group, as determined by the substitution pattern and configuration of the glycoside substrate.

- Mycobacterium abscessus complex (MABC) is an opportunistic bacteria that can cause severe pulmonary infections, leading to a study investigating its transmission in healthcare settings in Montréal.
- The research analyzed 221 bacterial isolates from 115 individuals between 2010-2018 for genetic similarities, revealing 28 sequence types and 210 pairs of isolates within a close genetic range, although no definitive person-to-person transmission was identified.
- The study concluded that while genomic analysis is helpful, it’s not enough to confirm MABC transmission in healthcare, suggesting that infections likely aren't spread directly between patients in these environments.
SNAP Online Food Shopping: Nutrition Education Needs Perceived by Practitioners.
J Nutr Educ Behav
November 2024
The change in policy that allowed Supplemental Nutrition Assistance Program recipients to redeem their benefits online during the coronavirus disease 2019 pandemic highlighted the potential role of nutrition education programs in facilitating the purchase of healthy, economical food online. The objective of this exploratory qualitative study was to understand the education provided by nutrition educators on online grocery shopping and educators' perspectives on education needs and ways that healthy purchases can be encouraged online. Interviews revealed topics that can be included in in-person education on online shopping, insights for online nutrition education, and promotion strategies for encouraging healthy purchases by low-income shoppers online.

However, we have only a poor understanding of what may be driving this variation. In this study, we used acoustic telemetry to quantify the spatial and temporal variations in river migration success in Atlantic salmon smolts on their first migration to sea.
