Identification and Health Risks of an Emerging Means of Drug Use in Correctional Facilities.

Importance: Recreational use of drug-soaked paper strips (hereafter, strips) in correctional facilities poses a major public health risk owing to the diverse and potentially severe toxic effects of the substances they contain. Understanding the clinical manifestations and outcomes of exposure to these strips is important for developing effective management and prevention strategies.

Objective: To characterize the clinical manifestations, management, and outcomes of intoxication from strips in a correctional facility population, and to identify the specific substances present in these strips.

Probing iron in Earth's core with molecular-spin dynamics.

Dynamic compression of iron to Earth-core conditions is one of the few ways to gather important elastic and transport properties needed to uncover key mechanisms surrounding the geodynamo effect. Herein, a machine-learned ab initio derived molecular-spin dynamics (MSD) methodology with explicit treatment for longitudinal spin-fluctuations is utilized to probe the dynamic phase-diagram of iron. This framework uniquely enables an accurate resolution of the phase-transition kinetics and Earth-core elastic properties, as highlighted by compressional wave velocity and adiabatic bulk moduli measurements.

Behavioral Alterations in Mice Exposed to Manganese via Drinking Water: Effects of Sex and a Lipopolysaccharide Challenge.

Manganese (Mn) is an essential and important metal; however, overexposures lead to adverse neurological outcomes. Nonoccupational Mn overexposure occurs primarily through consumption of Mn-contaminated drinking water (DW). Sex differences in terms of nervous and immune systems' responsiveness to excessive Mn in the DW are understudied.
