Influence of Polypyrrole on Phosphorus- and TiO-Based Anode Nanomaterials for Li-Ion Batteries.

Phosphorus (P) and TiO have been extensively studied as anode materials for lithium-ion batteries (LIBs) due to their high specific capacities. However, P is limited by low electrical conductivity and significant volume changes during charge and discharge cycles, while TiO is hindered by low electrical conductivity and slow Li-ion diffusion. To address these issues, we synthesized organic-inorganic hybrid anode materials of P-polypyrrole (PPy) and TiO-PPy, through in situ polymerization of pyrrole monomer in the presence of the nanoscale inorganic materials.

Lysophosphatidic Acid (LPA) Receptor 3-Mediated LPA Signal Transduction Pathways: A Possible Relationship with Early Development of Peri-Implantation Porcine Conceptus.

Lysophosphatidic acid (LPA) is a phospholipid with a variety of fatty acyl groups that mediates diverse biological effects on various types of cells through specific G protein-coupled receptors. LPA appears to play a significant role in many reproductive processes, including luteolysis, implantation, and placentation. Our previous study in pigs demonstrated that LPA and the LPA receptor system are present at the maternal-conceptus interface and that LPA increases uterine endometrial expression of prostaglandin-endoperoxide synthase 2 (PTGS2) through LPA receptor 3 (LPAR3).
