Aldehyde perception induces specific molecular responses in Laminaria digitata and affects algal consumption by a specialist grazer.

In the marine environment, distance signaling based on water-borne cues occurs during interactions between macroalgae and herbivores. In the brown alga Laminaria digitata from North-Atlantic Brittany, oligoalginates elicitation or grazing was shown to induce chemical and transcriptomic regulations, as well as emission of a wide range of volatile aldehydes, but their biological roles as potential defense or warning signals in response to herbivores remain unknown. In this context, bioassays using the limpet Patella pellucida and L.

The Rhodoexplorer Platform for Red Algal Genomics and Whole-Genome Assemblies for Several Gracilaria Species.

Macroalgal (seaweed) genomic resources are generally lacking as compared with other eukaryotic taxa, and this is particularly true in the red algae (Rhodophyta). Understanding red algal genomes is critical to understanding eukaryotic evolution given that red algal genes are spread across eukaryotic lineages from secondary endosymbiosis and red algae diverged early in the Archaeplastids. The Gracilariales is a highly diverse and widely distributed order including species that can serve as ecosystem engineers in intertidal habitats and several notorious introduced species.

[Castleman-like presentation of systemic lupus: About a case report].

Introduction: Castleman disease is a rare lymphoproliferation, which may mimic systemic lupus. Conversely, systemic lupus sometimes presents like an hematological malignancy. In these cases, a "Castleman-like" histology has been exceptionally described.

Loss of bone mineral density in hemiplegic patients after stroke: Prospective single-center study.

The aim of our prospective single-center study was to assess the loss of bone mineral density (BMD) in the year following stroke with hemiplegia. We evaluated functional disability and bone mineral density (BMD) in 18 patients immediately following and at 1 year of stroke with hemiplegia. The most significant variation in BMD concerns the femoral neck on the hemiplegic side: -0.
