Equity-oriented food supports: Learnings from the Nova Scotia COVID-19 pandemic response.

Setting: Public health measures enacted during the COVID-19 pandemic significantly impacted Nova Scotians experiencing food insecurity. Public Health (PH), Nova Scotia Health, created a provincial Housing Isolation Program (HIP) which addressed barriers to isolation, including food access, for COVID-19 cases and contacts being followed by PH.

Intervention: HIP worked with partners to coordinate and respond to urgent food needs of isolating clients by providing grocery and meal delivery options.

Synthesis, structural studies and Hirshfeld surface analysis of 2-[(4-phenyl-1-1,2,3-triazol-1-yl)methyl]pyridin-1-ium hexa-kis-(nitrato-κ ,')thorate(IV).

Reaction of thorium(IV) nitrate with 2-[(4-phenyl-1-1,2,3-triazol-1-yl)meth-yl]pyridine () yielded (H)[Th(NO)] or (CHN)[Th(NO)] (), instead of the expected mixed-ligand complex [Th(NO) ], which was detected in the mass spectrum of . In the structure, the [Th(NO)] anions display an icosa-hedral coordination geometry and are connected by H cations through C-H⋯O hydrogen bonds. The H cations inter-act N-H⋯N hydrogen bonds.

Neutral rhenium(I) tricarbonyl complexes with sulfur-donor ligands: anti-proliferative activity and cellular localization.

Rhenium(I) tricarbonyl complexes are widely studied for their cell imaging properties and anti-cancer and anti-microbial activities, but the complexes with S-donor ligands remain relatively unexplored. A series of six -[Re(NN)(CO)(SR)] complexes, where (NN) is 2,2'-bipyridyl (bipy) or 1,10-phenanthroline (phen), and RSH is a series of thiocarboxylic acid methyl esters, have been synthesized and characterized. Cellular uptake and anti-proliferative activities of these complexes in human breast cancer cell lines (MDA-MB-231 and MCF-7) were generally lower than those of the previously described -[Re(NN)(CO)(OH)] complexes; however, one of the complexes, -[Re(CO)(phen)(SC(Ph)CHC(O)OMe)] (3b), was active (IC ∼ 10 μM at 72 h treatment) in thiol-depleted MDA-MB-231 cells.

Rare Earths-The Answer to Everything.

Rare earths, scandium, yttrium, and the fifteen lanthanoids from lanthanum to lutetium, are classified as critical metals because of their ubiquity in daily life. They are present in magnets in cars, especially electric cars; green electricity generating systems and computers; in steel manufacturing; in glass and light emission materials especially for safety lighting and lasers; in exhaust emission catalysts and supports; catalysts in artificial rubber production; in agriculture and animal husbandry; in health and especially cancer diagnosis and treatment; and in a variety of materials and electronic products essential to modern living. They have the potential to replace toxic chromates for corrosion inhibition, in magnetic refrigeration, a variety of new materials, and their role in agriculture may expand.

Gallium reactivates first and second generation quinolone antibiotics towards drug-resistant .

Herein, we report on a series of homoleptic [GaL] and heteroleptic organometallic [GaMeL] complexes of inactive quinolone antibiotics; nalidixic acid, oxolinic acid and norfloxacin with their antibacterial activity (MIC 0.024-0.781 μM) towards four multi-drug resistant strains of through complexation to gallium.
