AbstractAnatomical forceps are used for the handling of sensitive structures in medicine. Structures which are manipulated with these forceps can get damaged or slip out of the grip of the forceps. This paper presents a forceps using the bionic Fin-Ray-Effect inspired by fish-fins in order to handle vulnerable structures in particular. During the process of development, functional models of this forceps were designed, 3D-printed and evaluated.

Razak A. 2018. The diversity of chemical compounds of bilih fish body (Mystacoleucus padangensis Bleeker) originating fromLake Toba and Lake Singkarak, Sumatra, Indonesia. Biodiversitas 19: 1552-1557. Bilih fish (Mystacoleucus padangensis) is anendemic fish in Lake Singkarak, West Sumatra. Bilih fish in Lake Singkarak experiencing pressure due to human activities that destroythe habitat of this fish in Lake Singkarak. The improvement of bilih fish habitat conducted by the government by introducing bilih fishto Lake Toba for bilih fish preservation. The purpose of this study is to describe the diversity of chemical compounds and their relationto several ecological factors that influence bilih fish in Lake Toba and Lake Singkarak. The research method is survey method. Bilih fishtaken at three to four points on both Lakes. The distance between sample points is 8000 m. The result of this research is to find themorphology of bilih fish from Lake Toba bigger than bilih Lake Singkarak fish. The bilih fish Fins of Lake Toba have a 52.08% CaOcompound (per 100 ppm sample), the fins of Lake Singkarak have a 53% CaO compound higher than Lake Toba, 51%. The content ofBilih Lake Toba fish muscle has P2O5 compounds 34,48% higher than Lake Singkarak with P2O5 34.58% higher, Bilih Danau Toba fishbone has CaO 57.66%, from Lake Singkarak 60,83%. Bilih Lake Toba has 97.32% Fluoride compound, higher than Lake Singkarak98.43%. The ecological conditions in Lake Toba are relatively similar to the condition of the waters in Lake Singkarak.

AbstractAcross the ∼30,000 species of ray-finned fish, fins show incredible diversity in overall shape and in the patterning of the supportive bony rays. Fin length mutant zebrafish have provided critical insights into the developmental pathways that regulate relative fin size. However, the processes that govern skeletal patterning along the proximodistal axis of the fin have remained less well understood. Here, we show that thyroid hormone regulates proximodistal identity of fin rays, distalizing gene expression profiles, morphogenetic processes during outgrowth, and ultimate morphology of the fin. This role for thyroid hormone in specifying proximodistal identity appears conserved between development and regeneration, in all the fins, and between species. We demonstrate that proximodistal identity is regulated independently from pathways that determine size, and we show that modulating proximodistal patterning relative to growth can recapitulate the spectrum of fin ray diversity found in nature.

AbstractFish cells are largely affected by their culture media. Fibroblast-like cells obtained from the fish fins can differentiate to various kinds of cells such as skeletal muscle-like, neurofilaments and adipocytes. Our results suggest that the fins which are usually discarded as food wastes may practically applied to the clean meat technology.
