Stocking, Enhancement, and Mariculture of Penaeus orientalis and Other Species in Shanghai and Zhejiang Provinces, China [PDF]

, 1997
China's marine aquaculture landings provide only 18% of its combined freshwater and amrine capture and culture landings, at a per-capita consumption of only 3.2 kg/yr out of a total of 18.1 kg/yr.

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Benralizumab for anti‐tumor necrosis factor‐associated eosinophilic gastrointestinal disease in a child with ileal Crohn's: A case report

JPGN Reports, EarlyView.
Abstract Crohn's disease (CD) and eosinophilic gastrointestinal diseases (EGIDs) are distinct inflammatory entities, but eosinophilic disease may emerge as a paradoxical immune complication of anti–tumor necrosis factor therapy. We report a 12‐year‐old boy with terminal ileal CD who developed severe eosinophilic gastritis and ileitis, peripheral ...

Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

An Update of Tetrodotoxins Toxicity and Risk Assessment Associated to Contaminated Seafood Consumption in Europe: A Systematic Review

Toxins
Following the occurrence of Tetrodotoxins (TTXs) in Europe—a group of neurotoxins identified in Asia, where fatalities occurred after the ingestion of contaminated pufferfish—the EFSA proposed a limit of 44 µg of TTX/kg of shellfish meat in mollusks in ...

The History, Present Condition, and Future of the Molluscan Fisheries of North and Central America and Europe: Volume 2, Pacific Coast and Supplemental Topics [PDF]

, 1997
Over 100 molluscan species are landed in Mexico. About 30% are harvested on the Pacific coast and 70% on the Atlantic coast. Clams, scallops, and squid predominate on the Pacific coast (abalone, limpets, and mussels are landed there exclusively). Conchs

"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

Journal of Quaternary Science, EarlyView.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Extraction of α-, β- and γ-chitosan from Portunus segnis, Sepia pharaonis and Aspergillus niger, and comparison of their antimicrobial activities

یافته‌های نوین در علوم زیستی, 2017
Three types of chitin as α (exoskeleton of crustaceans), β (cuttlebone of cephalopods) and γ (some fungal cell wall) exist in nature. Chitosan is the most important derivative of chitin, which has various biological activities.
