TL;DR: The inhibitory results indicate that the enzyme is a serine protease of the trypsin-like type and it is concluded that Holothuria polii cell-free coelomic fluid and coelomocyte lysate possess protease activity.
Abstract: 1. 1. Holothuria polii cell-free coelomic fluid and coelomocyte lysate possess protease activity. It depends on thermolabile enzymes influenced by pH and temperature but not affected by cations supplementation in the reaction medium. 2. 2. The protease is produced by coelomocytes which in vitro release it. 3. 3. The inhibitory results indicate that the enzyme is a serine protease of the trypsin-like type.

TL;DR: High bootstrap value and consistent clustering made Molpadia, Stichopus, Bohadschia and Actinopyga monophyletic, and the pairwise genetic distance calculated using Kimura 2-parameter model further supported and verified findings from the phylogenetic trees.
Abstract: This study aimed to determine phylogenetic relationship between and among selected species of sea cucumbers (Echinodermata: Holothuroidea) using 16S mitochondrial ribosomal RNA (rRNA) gene. Phylogenetic analyses of 37 partial sequences of 16S mitochondrial rRNA gene using three main methods namely neighbour joining (NJ), maximum parsimony (MP) and maximum likelihood (ML) showed the presence of five main genera of sea cucumbers: Molpadia from order Molpadiida and four genera of order Aspidochirotida namely Holothuria, Stichopus, Bohadschia and Actinopyga. All of the 17 species obtained from Malaysia distributed among the main genera except within Interestingly, Holothuria excellens was out of Holothuria group causing Holothuria to be paraphyletic. High bootstrap value and consistent clustering made Molpadia, Stichopus, Bohadschia and Actinopyga monophyletic. The relationship of with the other genera was unclarified and Stichopus was sister to Molpadia. The latter finding caused the resolution at order level unclear. The pairwise genetic distance calculated using Kimura 2-parameter model further supported and verified findings from the phylogenetic trees. Further studies with more samples and different mitochondrial DNA genes need to be done to get a better view and verification on the molecular phylogeny of sea cucumbers.

TL;DR: The importance of the Kiunga Marine National Reserve as a sanctuary in the conservation of the marine invertebrate fauna is stressed, based on the results of a field trip, and additional information from the literature.
Abstract: The echinoderm fauna of the Kiunga Marine National Reserve, Kenya, is documented, based on the results of a field trip, and additional information from the literature. In this first paper, the Holothuroidea and Echinoidea are discussed. A total of 91 specimens representing eight orders, 13 families, 19 genera and 37 species were collected. Five other species were not collected but were identified in the field. Six additional species are reported from literature only and are not discussed. Diagnostic characters of every species recorded are given, as well as an assessment of their abundance in the Kiunga Marine Reserve. Clypeaster rarispinus, Phyllacanthus imperialis, Microcyphus rousseaui (Echinoidea), Holothuria (Cystipus) rigida, Holothuria (Platyperona) difficilis, Labidodemas pertinax, Stichopus chloronotus and Stichopus cf. monotuberculatus (Holothuroidea) are new records for Kenya. Holothuria (Theelothuria) turriscelsa is a new record for the Indian Ocean. This study stresses the importance...

TL;DR: The results showed that FCShp and FCSht had beneficial effects on hematopoietic function recovery in CTX-induced bone marrow suppression mice, and provided basis for developing the drugs to reduce side effects of chemotherapy.
