A comprehensive approach for elucidating the interplay between 4f and 4f 5d configurations in Ln complexes.

Lanthanides (Ln) are typically found in the +3 oxidation state. However, in recent decades, their chemistry has been expanded to include the less stable +2 oxidation state across the entire series except promethium (Pm), facilitated by the coordination of ligands such as trimethylsilylcyclopentadienyl, CHSiMe (Cp'). The complexes have been the workhorse for the synthesis and theoretical study of the fundamental aspects of divalent lanthanide chemistry, where experimental and computational evidence have suggested the existence of different ground state (GS) configurations, 4f or 4f 5d, depending on the specific metal.

Xerostomia: a silent burden for people receiving palliative care - a qualitative descriptive study.

Background: The prevalence of dry mouth in the palliative care population is well documented and increases due to polypharmacy, radiotherapy and systemic conditions. Saliva as a lubricant for the mouth and throat has implications for swallowing, chewing, and speech. The literature about the experience of xerostomia (perceived feeling of dry mouth) in palliative care is scarce.

Physiological monitoring to prevent diving disorders.

Insight into human physiology is key to maintaining diver safety in underwater operational environments. Numerous hazardous physiological phenomena can occur during the descent, the time at depth, the ascent, and the hours after a dive that can have enduring consequences. While safety measures and strict adherence to dive protocols make these events uncommon, diving disorders still occur, often with insufficient understanding of the factors that triggered the event.

Approaching Universal Prenatal Detection of Significant Cardiovascular Malformations in Nevada.

Objective: To report our recent experience with prenatal detection of significant cardiovascular malformations (CVMs) in Nevada's state-wide maternal population receiving prenatal care.

Methods: We queried our databases for those with significant CVMs diagnosed pre- or postnatally between May 1, 2021, and April 30, 2024. We defined CVMs as those that required, would have required, or will likely require a therapeutic procedure in the first 12 months.

Three Developments Related to ANSI/HPS Standard N13.56.

Three topics related to ANSI/HPS Standard N13.56, Sampling and Monitoring Releases of Airborne Radioactivity in the Workplace, are discussed. First, due to the omission of consideration of the activity's half-life in the standard's continuous particulate air monitor (CPAM) quantitative method, it is possible for concentration estimates produced by that calculation to be underestimated.
