Article Synopsis
  • The red king crab and Japanese mitten crab are important for both their nutritional value and ecological research.
  • A study focused on the changes in lipid profiles during the crabs' embryonic and larval stages, highlighting how triacylglycerols disappeared in early larvae but reappeared later with different compositions.
  • The research revealed species-specific demands for polyunsaturated fatty acids, which could guide better diet selection in aquaculture practices.

Objectives: The use of infrapatellar fat pad adipose stem cells (IPFP-ASCs) shows an age-independent proliferation and differentiation potential. In addition, the pronounced chondrogenic potential of IPFP-ASCs makes them promising candidates for research for use in other methods of regenerative therapy. The purpose of this study was to ascertain the presence and compare the relative abundance of cells exhibiting an immunohistochemical profile characteristic of adipose-derived mesenchymal stem cells in selected samples of the stromal vascular fraction (SVF) obtained from the IPFP and subcutaneous fat tissue.

Delayed union of fractures is one of the most frequent complications in orthopedic practice, especially in polytrauma patients. With the development of new methods of regenerative medicine, including the use of adipose derived stromal cells as a component of the stromal-vascular fraction (SVF), new possibilities for conservative treatment of this problem have emerged. This article presents a clinical case of conservative treatment of delayed union of a radial bone fracture using local SVF injections.

This article presents recent findings as regards distribution of cells producing serotonin and dopamine in the larval central nervous system at different developmental stages, including four pelagic larval stages (zoea I-IV), a semibenthic postlarval stage glaucothoe (megalopa), benthic juveniles, and adult red king crabs, , made by using immunocytochemistry and confocal laser scanning microscopy. We have shown that the serotonergic and dopaminergic neurons are present long before the onset of metamorphosis. In the red king crab b larval nervous system, the changes become particularly pronounced during the first metamorphosis from zoea IV to glaucothoe, which may be related to the development of the segmental appendages and maturation of motor behaviors in decapods.

The digestive system structure in pre-zoea and zoea I larvae of the red king crab Paralithodes camtschaticus has been examined. During this development period, the digestive system consists of an esophagus, a stomach, a midgut (where the hepatopancreas ducts open), and a hindgut. The esophagus begins from the oral slit on the animal's ventral side and extends vertically up to the junction with the cardiac stomach.
