The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Hyponatremia is a common electrolyte disorder in the emergency department (ED), but its clinical burden is not evenly distributed across the sodium spectrum. We conducted a retrospective observational cohort study of adult ED encounters at a tertiary referral hospital between July 2019 and July 2024 to identify a data‐driven threshold for ...

Synthesis of Microbial‐Derived Octadecanoids
Lipids, EarlyView.C18‐carbon containing dietary polyunsaturated fatty acids (e.g., linoleic acid, α‐linolenic acid, and γ‐linolenic acid) are metabolized by bacteria in the gut into oxygenated lipid mediators termed octadecanoids. To study the biological function of these compounds, we report here the chemical synthesis of multiple octadecanoids.

A Boothby–Wang Construction in Generalized Contact Geometry
Mathematische Nachrichten, EarlyView.ABSTRACT We establish a generalized analogue of the Boothby–Wang theorem in generalized contact geometry, along with related results. We present a general method for constructing examples of generalized contact structures that are not of Poon–Wade type, and even examples that fail to be generalized contact structures.
