Marine cross-border areas are ideal for monitoring pollutants so as to increase ecosystems protection. This study was conducted at the Romanian-Ukraine border of the Black Sea to reveal evidence of contamination with toxic metals based on... more
Assesing the influence of the leaf extract to histopathological on hepatopancreas of shrimp as protection from Vibrio harveyi. Crude, ethyil acetate, and n-butanol fraction was given by dipping method. The best survival was the fraction... more
The influence of sinus and mandibular glands on the metabolism of the Ocypode macrocerawas studied. Carbohydrate content of heart, hepatopancreas, muscles and hemolymph of eyestalk extract injected crabs was significantly higher than that... more
Selenoneine, 2-selenyl-Nα, Nα, Nα-trimethyl-L-histidine, is the major organic selenium compound in marine fish. To characterize biological antioxidant function of selenoneine in fish, the accumulation of selenoneine and other selenium... more
This paper describes the first systematic monitoring conducted in 2002 at shrimp farms in Sinaloa and Sonora (Mexico) for the presumptive and confirmative diagnosis of necrotizing hepatopancreatitis bacterium (NHPB) in Litopenaeus... more
A 12-day experiment was conducted to investigate the effects of Artemia enrichment with two experimental microalgal emulsions (formulated with selected fatty acid contents) on Penaeus vannamei postlarvae. For this purpose, 405,000... more
“ Candidatus Hepatoplasma crinochetorum” Ps is an extracellular symbiont residing in the hepatopancreas of the terrestrial isopod Porcellio scaber . Its genome is highly similar to that of the close relative “ Ca. Hepatoplasma... more
Slow growth rate tends to be a challenge in the cultivation of spiny lobster (P. homarus) because it impact on long rearing periods and high operational costs, especially for feeds. Short-term starvation or fasting has known to allow the... more
The presence of a xenobiotic in the environment can often represent a risk for living organisms. Quaternium-15, a preservative, is one of the most used substances and is added to several cosmetics and other industrial products. For this... more
This study investigated the effects of dietary supplementation of combined black cumin (BC) and grape seed (GS) powder at different rates (0%, 1%, 2%, and 4%, respectively) on growth performance and hepatopancreas histology of third... more
PirAB is a binary protein complex secreted by specific strains of Vibrio parahaemolyticus (Vp) that harbor the pVA1 virulence plasmid and express PirAVp and PirBVp toxins. PirABVp causes acute hepatopancreatic necrosis disease (AHPND), a... more
Vibrio parahaemolyticusstrains have been identified as the causative agent of acute hepatopancreas necrosis disease (VpAHPND+) in shrimp. In the present work, a highly virulent (M0904) and less virulent (M0607) strain ofVpAHPND+ were used... more
Moribund shrimp affected by acute hepatopancreatic necrosis disease (AHPND) from farms in northwestern Mexico were sampled for bacteriological and histological analysis. Bacterial isolates were molecularly identified as Vibrio... more
Vibriosis is one of the most widespread infectious diseases of cultured shrimp in Mexico; as a result, the Research Centre for Food and Development (CIAD, for the Spanish wording) offers a diagnostic service to the shrimp farmers where... more
Lobster (Homarus americanus) hepatopancreas is a complex, heterogeneous tissue composed of four epithelial cell types that individually contribute to the overall functional properties of digestion, absorption, secretion, and... more
SUMMARYCrustacean hepatopancreatic lysosomes are organelles of heavy metal sequestration and detoxification. Previous studies have shown that zinc uptake by lysosomal membrane vesicles (LMV) occurred by a vanadate- and... more
SUMMARYThis study describes the membrane transport mechanisms used by lobster (Homarus americanus) hepatopancreatic epithelial lysosomes to accumulate and sequester heavy metals from the cytosol, and thereby aid in the regulation of these... more
This study aimed to describe the Macrobrachium rosenbergii hepatopancreas histomorphology. The hepatopancreas is constituted by a set of blind end tubules, divided into proximal, middle, and distal regions, with the epithelium formed by... more
The effect of biofloc (BFT) and clear water (CW) at low (ls) and high-water salinity (hs) in wild juveniles of Penaeus setiferus were evaluated. Four treatments were implemented: hsBFT, lsBFT, hsCW, and lsCW. After 45 days, final weight... more
