Intercalation of Neutral Guests in Pillared Salt Cocrystals of 5-Ureidosalyclic Acid.

The salts of 5-ureidosalyclic acid (5-USA) form a range of pillared salt inclusion complexes from basic solvents, namely, triethylamine, piperidine, morpholine, and 4-ethylpyridine. The triethylamine derivative is unsolvated, while the other salts include 1-3 solvent molecules of formula XH(5-USA-H)·X (X = morpholine, = 1, 2, and 3 ( - ); X = 4-ethylpyridine, = 1 () and X = piperidine, = 2.5 ()).

Drinking private well water: Groundwater quality and management of wells in southern Alabama.

Private wells provide a source of household water for over 40 million people in the United States and an estimated 1 million people in the Coastal Lowlands Aquifer system along the Gulf of Mexico. Well water quality is dependent on the local geology and factors that contribute to anthropogenic contamination from the surface. Here, we evaluated groundwater quality and well management in southern Alabama, USA, to better understand factors that influence exposures through drinking water from private wells.

Enterotoxemia in a 2-day-old lamb produced by a type D lambda toxin-positive strain.

type D is a gram-positive bacterium that causes enterotoxemia in sheep, goats, and, less frequently, other animals. This microorganism encodes 2 major toxins, alpha (CPA) and epsilon (ETX). Enterotoxemia occurs when epsilon prototoxin (pETX) is produced in the intestine and is activated by one or more proteases before being absorbed into the general circulation.

Characteristics and Outcomes of Children Hospitalized With COVID-19 During Early Pandemic and Delta Variant.

Children were less affected by severe illness as compared to adults at the start of the COVID-19 pandemic. As the pandemic progressed and variants emerged, pediatric hospitalizations increased, and some previously healthy children developed multisystem inflammatory disorder. The aim of this study was to describe the characteristics and outcomes of children hospitalized with COVID-19 from the beginning of the pandemic through the Δ variant.
