Sea urchins are model non-chordate deuterostomes, and studying the nervous system of their embryos can aid in the understanding of the universal mechanisms of neurogenesis. However, despite the long history of sea urchin embryology research, the molecular mechanisms of their neurogenesis have not been well investigated, in part because neurons appear relatively late during embryogenesis. In thi...

A neuritogenic monoglyceride, 1-O-(myristoyl) glycerol (MG), was isolated from the head of Ilisha elongate using a PC12 cell bioassay system, and its chemical structure was elucidated using spectroscopic methods. MG significantly induced 42% of the neurite outgrowth of PC12 cells at a concentration of 10 μM. To study the structure-activity relationships of MG, a series of monoglycerides was des...

The taxonomy of clupeiforms has been extensively studied, yet phylogenetic relationships among component taxa remain controversial or unresolved. Here we test current and new hypotheses of relationships among clupeiforms using mitochondrial rRNA genes (12S and 16S) and nuclear RAG1 and RAG2 sequences (total of 4749bp) for 37 clupeiform taxa representing all five extant families and all subfamil...

Background: Fish is an important source of food for people. According to the FAO, It man’s most single high-quality protein and dietary omega-three fatty acids. Objective: The study consisted chemical characterization oil extracted from Ilisha africana and Sardinella maderensis being fish species Cameroonian coast. Material methods: were collected at fishing port Douala, transport...

Assessment of fish stock status is generally required for fisheries management, which difficult when the data are limited. The length-based Bayesian Biomass (LBB) approach a powerful and new method, where only length-frequency used estimating resources. Here, we applied LBB method to assess seven commercially valuable marine fishes from northern tip Bay Bengal (BoB), Bangladesh. These species w...
