Oral administration of siRNA is a challenging strategy for the local treatment of intestinal diseases, including cancer and inflammatory bowel disease. Both nucleic acids and delivery systems, especially lipid nanoparticles (LNPs), are sensitive to the acidic pH of the stomach, bile salts and digestive enzymes. The present work focuses on the design and evaluation of gastroresistant alginate microparticles (MPs) prepared with an original process for oral delivery of siRNA.

At least 1 in 4 women seek pelvic floor care and many more suffer with concurrent symptoms of bowel, bladder and sexual dysfunction, which can have a large impact on quality of life. It is estimated that 1 in 5 women will undergo surgery for POP.

Sacrospinous ligament suspension is used for suspension of apical prolapse; however, it has a high rate of recurrence compared with sacrocolpopexy, and a high rate of pain compared with uterosacral suspension. We developed a novel surgical procedure of bilateral sacrospinous vaginal vault fixation with synthetic mesh arms. We previously demonstrated its safety, and in Supplementary video 1, we describe a step-by-step surgical approach that could be replicated.

Metabolic pathways are affected by the impacts of environmental contaminants underlying a large variability of toxic effects across different species. However, the systematic reconstruction of metabolic pathways remains limited in environmental sentinel species due to the lack of available genomic data in many taxa of animal diversity. In this study we used a multi-omics approach to reconstruct the most comprehensive map of metabolic pathways for a crustacean model in biomonitoring, the amphipod Gammarus fossarum in order to improve the knowledge of the metabolism of this sentinel species.
