In vitro, in the hemocytes of the marine mussel Mytilus hemocytes, suspension of TiO2 NPs (Degussa P25, 10 μg/ml) stimulated immune and inflammatory responses, such as lysozyme release, oxidative burst and nitric oxide production. Vevers and Jha demonstrated the intrinsic genotoxic and cytotoxic potential of TiO2 NPs on a fish-cell line derived from rainbow-trout gonadal tissue (RTG-2 cells) after 24 h of exposure to 50 μg/ml. Reeves et al. demonstrated a significant increase in the level of oxidative DNA damage in goldfish cells, and suggested that damage could not repaired by DNA repair mechanisms. Another suggestion from the mentioned study was that hydroxyl radicals are generated also in the absence of UV light. It has been shown that fish cells are generally more susceptible to toxic/oxidative injury than mammalian cells.

  • In conclusion, long arm stitching machines offer a range of benefits that make them a valuable investment for sewers of all skill levels. With their spacious workspace, greater visibility, versatility, and advanced features, these machines make sewing and stitching easier, faster, and more enjoyable. If you're looking to upgrade your sewing equipment and take your projects to new heights, consider adding a long arm stitching machine to your collection.


  • The Mechanism Behind Chain Stitch Machines


  • One of the standout advantages of using a hand crank leather stitching machine is the quality of the stitches produced. These machines typically utilize a saddle stitch technique, which is renowned for its strength and durability. Unlike a straight stitch, the saddle stitch interlocks the two threads, resulting in a more robust seam that can withstand the wear and tear of everyday use. This makes hand crank machines particularly popular among leatherworkers creating high-quality items such as belts, wallets, bags, and more.
