...Patricia A. Wright; Chris M. Wood; Jonathan M. Wilson Increased renal ammonia excretion in response to metabolic acidosis is thought to be a conserved response in vertebrates. We tested the hypothesis that Rhesus (Rh) glycoproteins in the kidney of the freshwater common carp, Cyprinus carpio , play...

... to increase the mass of backward accelerated water during swimming. The amount, dimensions, orientation and growth of actinotrichia were measured at various locations along the finfold in several developmental stages of common carp ( Cyprinus carpio ) and zebrafish ( Danio rerio ). Actinotrichia morphology...

.... Such heterotopic thyroid follicles are active,and considered to work in concert with the subpharyngeal thyroid. In Mozambique tilapia ( Oreochromis mossambicus ) thyroid activity is,indeed, restricted to the subpharyngeal region; in common carp ( Cyprinus carpio ) the functional endocrine thyroid is associated...

... manifestations. Construction of a cDNA microarray led to a survey of transcript expression levels in seven tissues of carp, as a function of time,and three different extents of cooling. The resulting data delineated a common stress response found in all tissues that comprises genes involved in cellular...

... differences from the high turnover carp rbc CA( Esbaugh et al., 2004 ). Even more intriguing, none of the mentioned amino acid differences appear in residues that have been implicated in enzyme function( Stams and Christianson,2000 ). The same trend arises when lamprey CA is compared to mammalian CA isozymes...

...Yoshiaki Nihei; Atsushi Kobiyama; Daisuke Ikeda; Yosuke Ono; Satoshi Ohara; Nicholas J. Cole; Ian A. Johnston; Shugo Watabe SUMMARY Three embryonic class II myosin heavy chains (MYHs) were cloned from the common carp ( Cyprinus carpio L.), MYH emb1 ,MYH emb2 and MYH emb3 . MYH DNA clones were also...

...Margarita I. Concha; Rodrigo López; Julieta Villanueva; Nadya Báez; Rodolfo Amthauer SUMMARY High density lipoprotein (HDL) has been shown to play an important role in the dietary lipid mobilisation in the carp. In spite of this, previous studies have failed to demonstrate the synthesis...

...Nicholas J. Cole; Thomas E. Hall; Christopher I. Martin; Mark A. Chapman; Atsushi Kobiyama; Yoshiaki Nihei; Shugo Watabe; Ian A. Johnston SUMMARY Embryos of the common carp, Cyprinus carpio L., were reared from fertilization of the eggs to inflation of the swim bladder in the larval stage at 18...

... the opercular slits. In crossflow filtration, the particle suspension is pumped parallel to the filter surface as filtrate exits through the filter pores, causing the suspension to become more concentrated as it travels downstream along the filter. We used high-speed video endoscopy to determine whether carp...

...S. Brooks; G. T. Clark; S. M. Wright; R. J. Trueman; A. D. Postle; A. R. Cossins; N. M. Maclean SUMMARY Cold acclimation of carp from 30°C to 10°C causes a restructuring of liver microsomal phospholipids characterised by increased proportions of monounsaturated fatty acid in phosphatidylcholine (PC...

...Shugo Watabe SUMMARY Three myosin heavy chain isoforms with different actin-activated Mg 2+ -ATPase activities were found in the fast skeletal muscle from carp ( Cyprinus carpio ) acclimated to 10 and 30°C. The composition of three types of myosin heavy chain was dependent on acclimation...

...Frank B. Jensen SUMMARY Autoxidation of oxyhaemoglobin (oxyHb) to methaemoglobin was measured at different temperatures in haemoglobin solutions from Atlantic hagfish, river lamprey, common carp, yellowfin tuna and pig. The aims were to evaluate the impact of the absent distal histidine in hagfish...

...SHIN OIKAWA; YASUO ITAZAWA The relationships of resting metabolism per unit mass of body to gill and body surface areas were examined by measuring gill, body surface and fin areas of carp ranging from 0.0016 to 2250g. There was a triphasic allometry for the relationship between gill area and body...
