Density of vibrios in hemolymph and hepatopancreas
of diseased Pacific white shrimp, Litopenaeus vannamei, from northwestern Mexico.
piscinalis, microscopic examination of these mollusks' hepatopancreas
was not carried out.
For histopathological analysis, hepatopancreas
tissues were immersion-fixed in Davidson's solution and stained by standard Hematoxylin and Eosin staining method as described previously (16).
The ovary and hepatopancreas
are the two main edible parts of females; therefore, the status of their gonadal development directly affects their food values and market price (Jiang et al.
Some nutrients are differentially deposited in the body: lipids are mainly stored in the hepatopancreas
, which is located in the cephalothorax, while proteins are mainly stored in the muscle, which is mostly located in the pleon.
Certified and obtained values of elements concentration ([micro]g x [g.sup.-1] dry weight) in the certificate reference materials (TORT-2; lobster hepatopancreas
) and (DORM-3; fish protein).
Isolation: 73.5 g hepatopancreas
of freshly collected 60 mussels were homogenized in 200 mL of 10 mM Tris-HCl containing 1 mM EDTA, pH 7.5 buffer (TE buffer) by means of a homogenizer (Art-MICCRA D-1, Heitersheim, Deutschland).
Aquello, generalmente se acompana del organo perigastrico, anteriormente conocido como hepatopancreas
(Cervellione et al.
The muscle and the hepatopancreas
take part in adjustment mechanisms subsidiary to osmo-ionoregulation (Li et al., 2008; Martins et al., 2011; Michiels et al., 2013; Pinoni et al., 2013; Longo & Diaz, 2015).
Se han reportado estudios proteoliticos en carpa donde se determinaron optimos de actividad proteolitica a pH 2.7-3.7 para aspartil proteasas del musculo (Goldman-Levkovitz, Rimon, & Rimon, 1995), a pH 2.5 para catepsinas D (Liu, Wang, & Zhang, 2008), y actividad proteolitica maxima a pH de 5.5 a 6.5 para cistein proteasas del hepatopancreas
(Aranishi, Hara, Osatomi, & Ishihara, 1997), que concuerdan con lo obtenido en este estudio para proteasas con actividad a pH acido.
Jumbo squid is an important fishery in Mexico, usually sold as frozen or cooked-frozen gutted mantle (Luna-Raya et al., 2006), after the hepatopancreas
is removed, as it represents a source of contamination.
