Lysophosphatidic acids (LPAs) are biologically active signaling molecules involved in the regulation of many cellular processes and have been implicated as potential mediators of fibroblast recruitment to the pulmonary airspace, pointing to possible involvement of LPA in the pathology of pulmonary fibrosis.LPAs have been measured in various biologi
The author argues through an analysis of maritime practice, legal theory and statutory enactments that the pilot is not only an expert adviser but that he takes charge of and conducts a vessel.He distinguishes between Betaine HCl/Pepsin/Gentian Bitters conducting and commanding and points out that by recognizing that the pilot conducts a ship no ch
