The claw closer muscle of Neohelice granulata (Grapsoidea, Varunidae): a morphological and histochemical study

Acta Zoologica (2010)

María Victoria Longo Adriana L. Goldemberg Alcira Ofélia Díaz

Longo, M.V., Goldemberg, A.L. and Díaz, A.O. 2011. The claw closer muscle of Neohelice granulata (Grapsoidea, Varunidae): a morphological and histochemical study. —Acta Zoologica (Stockholm) 92: 126–133. The claw closer muscle of Neohelice granulata was studied according to histological, histochemical, and morphometrical criteria. Adult male crabs in intermoult stage were collected from Mar Chiquita Lagoon (Buenos Aires, Argentina). Muscle fibers show evident striations and oval-elongated nuclei with loose chromatin. The loose connective tissue among muscle fibers consists of cells and fibers embedded in an amorphous substance. Muscle histochemistry reveals two slow fiber types: ‘A’ and ‘B’. Prevailing A fibers are larger, and they usually show, with respect to B type, a weaker reaction to whole techniques. Fibers with short (SS), intermediate (IS), and long sarcomeres (LS) appear in the claw closer muscle, being the LS fibers predominant. Concluding, the histochemical and morphometrical characteristics of the claw closer muscle fibers of N. granulata are indicative of slow fibers. The slow A type (low resistant to fatigue) prevails.

Studies of the claws of the crab Cyrtograpsus angulatus Dana (Crustacea, Brachyura, Grapsidae)

Biociências (On-line) (2007)

Analía Verónica Fernández-Giménez Adriana L. Goldemberg Alcira Ofélia Díaz

The present work describes the histological characteristics and composition of the closer muscle fibers of Cyrtograpsus angulatus (Dana, 1851). Intermolt adult males were sampled in Mar Chiquita lagoon (Buenos Aires, Argentina). The claws were dissected and processed by standard histological and histochemical techniques. The composition of the fibers present in the muscle was analyzed measuring the sarcomere length at three different zones (dorsal, central and ventral). Muscular fibers showed evident striation, elongated nuclei with finely granular nuclear chromatin, and abundant loose connective tissue with amorphous substance, melanin, collagen fibers and haemocytes. The closer muscle presents different kind of fibers, being predominant the slower fibers. The relationship between the structure and function of the muscle and the possible correspondence between the mechanical power produced by the closer muscle and the sarcomere length of the fibers is under discussion. Keywords: Brachyura, claw, crab, Crustacea, histology, sarcomere.

Histology of the liver of Oligosarcus jenynsii (Ostariophysi, Characidae) from Los Padres Lake, Argentina

Iheringia Série Zoologia (2006)

Gladys M. Petcoff Alcira Ofélia Díaz Alicia H. Escalante Adriana L. Goldemberg

The liver is an organ notable for its sensitivity to a great variety of environmental factors. It is composed of a parenchyma divided into irregular lobules by the exocrine pancreas or hepatopancreas; the pancreatic cells are arranged around a branch of the portal vein. The hepatocytes are radially arranged in cords around a central sinusoid. The liver histomorphology and the organization of exocrine pancreatic tissue of O. jenynsii (Günther, 1864) is similar to the acinar morphology of many teleosts, including freshwater and marine species. The aim of the present work was to carry out the histological analysis of the liver of Oligosarcus jenynsii, one of the most common species inhabiting Los Padres Lake (Buenos Aires Province, Argentina).

Characterization of Lateral Musculature in the Striped Weakfish (Cynoscion striatus Cuvier)

Anatomia Histologia Embryologia (1998)

C. V. Devincenti Alcira Ofélia Díaz Adriana L. Goldemberg

Summary Histochemical and ultrastructural studies were performed on lateral musculature from individual female weakfish ( Cynoscion striatus Cuvier). Based upon SDH, PhR, Sudan and myosin‐ATPase determinations, different kinds of red, pink and white fibres were discerned at the anterior, medium and posterior regions. Levels of glycolytic activity increased from red to white fibres, being intermediate in the pink ones. Contrarily, oxidative activity decreased from red to pink and white fibres. Histochemical stain showed a complex distribution of fibre types in each layer. A considerable variation in size and distribution was also found among fibres.

Glycoproteins histochemistry of the gills of Odontesthes bonariensis (Teleostei, Atherinopsidae)

Journal of Fish Biology (2010)

A. O. Díaz A. M. García Alicia H. Escalante Adriana L. Goldemberg

The histochemistry of glycoproteins (GP) in the mucous cells of the gills of the silverside Odontesthes bonariensis was identified with: (1) oxidizable vicinal diols; (2) sialic acid and some of their chain variants, carbon 7 ( 7 C), carbon 8 ( 8 C) or carbon 9 ( 9 C); (3) sialic acid residues without O‐acyl substitution and with O‐acyl substitution at 7 C, 8 C or 9 C; (4) carboxyl groups and (5) sulphate groups. A battery of seven biotinylated lectins allowed GPs sugar residues to be distinguished. Mucous cells showed the presence of neutral, sulphated and sialylated GPs. Dolichos biflorus agglutinin (DBA) and Glycine max agglutinin (SBA) showed strong positive staining; Arachis hypogaea agglutinin (PNA), Ricinus communis agglutinin‐I (RCA‐I) and Triticum vulgaris agglutinin (WGA) showed moderate staining, while Ulex europaeus agglutinin‐I (UEA‐I) was completely negative.

Characterization of the Swimming Muscle of the Anchovy Engraulis anchoita (Hubbs & Martini 1935)

Anatomia Histologia Embryologia (2000)

C. V. Devincenti Alcira Ofélia Díaz Adriana L. Goldemberg

The lateral muscle characteristics of individual female anchovies (Engraulis anchoita) were studied by histochemical and ultrastructural techniques. Red, pink and white fibres were discerned on the basis of the activity of the metabolic enzymes succinic dehydrogenase, phosphorylase and myofibrilar ATPase, and the usage of Sudan and periodic-acid Schiff staining techniques. Red fibres were located at the surface, white fibres deep inside and pink fibres in between. The red fibres appeared flattened or ribbon-shaped in transverse section and they were located in rows separated by myosepta of connective tissue. The red and pink fibres were multi-innervated whereas the white fibres were terminally innervated. The relative proportion of the red muscle increased toward the caudal region, the white muscle diminished toward that region, whereas the proportion of pink muscle did not vary according to region, being scarce throughout. The distribution of capillaries was also investigated, and as a result, the vascular supply proved to be scarce in both white and pink muscle.

Biochemical and Physicochemical Properties of Actomyosin from Pre‐ and Post‐spawned Hake (Merluccius hubbsi) Stored on Ice

Journal of Food Science (1990)

Sara I. Roura Claudia Montecchia Adriana L. Goldemberg Raúl E. Trucco Marcos Crupkin

ABSTRACT Biochemical and physicochemical properties of natural actomyosin (NAM) from pre‐ and post‐spawned hake stored on ice were studied. At the beginning of storage both reduced viscosity and ATPases activities of NAM from post‐spawned hake were about 3 times higher than those of the pre‐spawned ones, except for the Mg 2+ ‐(Ca 2+ )‐ATPase. Higher loss of functional components during pre‐spawned hake NAM purification was found compared to NAM from post‐spawned fish. Reduced viscosity and Mg 2+ ‐(EGTA)‐ATPase activity of NAM from both pre‐ and post‐spawned hake decreased following ice storage. SDS‐PAGE patterns of NAM from pre‐spawned hake showed an absence of the myosin heavy chain and the presence of a 160 kDa component at zero time of storage. No proteolysis occurred in ice‐stored fish caught in both gonadal stages.
