Multisystemic inflammatory disease in Pheasantshell (Unionidae, Actinonaias pectorosa) associated with Yokenella regensburgei infection at sites experiencing seasonal mass mortality events.

Freshwater mussels are integral components of riverine ecosystems, influencing water quality, nutrient cycling, and habitat characteristics. Enigmatic freshwater mussel declines, often characterized by sudden mass mortality events, pose significant challenges to conservation efforts. The Clinch River, a freshwater biodiversity hotspot in Virginia and Tennessee, USA, has experienced several enigmatic mass mortality events since 2016.

Panmixia in the American eel extends to its tropical range of distribution: Biological implications and policymaking challenges.

The American eel () has long been regarded as a panmictic fish and has been confirmed as such in the northern part of its range. In this paper, we tested for the first time whether panmixia extends to the tropical range of the species. To do so, we first assembled a reference genome (975 Mbp, 19 chromosomes) combining long (PacBio and Nanopore and short (Illumina paired-end) reads technologies to support both this study and future research.

Embodiment and the foundation of biographical disruption.

The concept of biographical disruption has now enjoyed nearly 40 years of use in medical sociology. This paper argues that taking an embodied approach to biographical disruption helps to explain the concept's enduring efficacy. Drawing on the work of Maurice Merleau-Ponty and contemporary theories of embodiment inspired by his phenomenology, this paper advances that biographical disruption involves, in the first instance, a disruption to the ability to enact an embodied orientation towards the world.

Increased plasma hyaluronan in severe pre-eclampsia and eclampsia.

Pre-eclampsia is a serious multi-system disorder with general endothelial disease, often with a component of hepatic dysfunction. The pathogenesis of preeclampsia is not fully understood, and no specific diagnostic tests are available for early and reliable diagnosis, or for monitoring of the disease process. Hyaluronan is an extracellular matrix polysaccharide present at low concentrations in plasma.

Crystalloid infusion increases plasma hyaluronan.

Objective: To investigate the changes in plasma hyaluronan concentrations after intravenous infusion of crystalloid solution in healthy subjects.

Design: Crossover, controlled study.

Setting: General intensive care unit in a university hospital.
