...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...

...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...

...R. J. Trueman; P. E. Tiku; M. X. Caddick; A. R. Cossins ABSTRACT Cold acclimation induces a transient enzymatic activation of the acyl CoA-Δ 9 -desaturase in carp liver. We have determined thresholds for two underlying mechanisms; namely, the activation of latent enzyme and the induced synthesis...

...J. C. Fenwick; S. E. Wendelaar Bonga; G. Flik ABSTRACT In vivo treatment with external bafilomycin A 1 , a selective inhibitor of V-ATPase H + pumps, reduced whole-body Na + influx by up to 90 % in young tilapia and 70 % in young carp. The inhibition was rapidly reversible, with whole-body Na...

...James M. Wakeling; Kirsty M. Kemp; Ian A. Johnston ABSTRACT Common carp Cyprinus carpio L. were reared a constant temperature of 20 °C from the larval (7 mm total length) to the juvenile (80 mm) stage. Body morphology and white muscle mass distribution were measured. Fast-start escape responses...

... pulse in voltage-clamped heart cells, we examined sarcolemmal Ca 2+ influx through Na + /Ca 2+ exchange and L-type Ca 2+ channels in crucian carp ( Carassius carassius L.) ventricular myocytes. When other cation conductances were blocked, a Ni 2+ -sensitive current with the characteristic voltage...

... in a species of fish. In this study, we identify two developmentally regulated MyoHC gene transcripts (named Eggs22 and Eggs24 ) in carp ( Cyprinus carpio ) and characterise their expression patterns during embryonic and larval development. The transcripts showed an identical temporal pattern of expression...

...James M. Wakeling; Ian A. Johnston ABSTRACT Fish fast-starts are rapid events caused by the simultaneous onset of muscle activity along one side of the body. Spine curvature and the strain and electromyographic activity in white muscle were measured for fast-starts in the common carp Cyprinus...

...Igor L. Y. Spierts; Johan L. Van Leeuwen ABSTRACT An analysis is presented of body curvature, acceleration and muscle strain during fast-starts in the common carp ( Cyprinus carpio L.). C- and S-starts were filmed at 200 frames s −1 at 23 °C. Curvatures and accelerations of mid-body axes were...
