The roles of tissue nitrate reductase activity and myoglobin in securing nitric oxide availability in deeply hypoxic crucian carp [PDF]

open access: yes, 2016
In mammals, treatment with low doses of nitrite have cytoprotective effects in ischemia/reperfusion events, due to nitric oxide formation and S-nitrosation of proteins.

Hira基因产物在银鲫和彩鲫卵子发生过程中的动态变化 [PDF]

open access: yes, 2010
为进一步研究Hira基因在卵子发生和雌核发育过程中的作用,通过原位杂交和免疫荧光定位的方法检测了Hira mRNA和蛋白质在雌核发育银鲫和两性生殖彩鲫卵子发生过程中的动态变化。结果表明,银鲫和彩鲫卵子发生过程中Hira基因转录产物的变化基本一致,在Ⅰ期卵母细胞的细胞核中大量表达,至Ⅱ期卵母细胞时转至细胞质中均匀分布,在Ⅲ期卵母细胞中,杂交信号逐渐移向细胞的周边,到Ⅳ期时随着卵黄物质大量积累,杂交信号几乎不见。HIRA蛋白在银鲫和彩鲫卵子发生过程中的变化略有差别。HIRA蛋白在银鲫Ⅰ期卵母细胞中没有表达,

Differential gene expression of protein kinases in oocytes between natural gynogenetic silver crucian carp and amphimictic crucian carp

open access: yesChinese Science Bulletin, 1999
A modified mRNA differential display method has been applied to studying differential expression of protein kinase genes in oocytes between natural gynogenetic silver crucian carp and amphimictic crucian carp. Total RNA was reverse transcribed using downstream 3′ primers T12MA, T12MG and T12MC respectively.

Electrical excitation of the heart in a basal vertebrate, the european river lamprey (Lampetra fluviatilis) [PDF]

open access: yes, 2014
Hagfishes and lampreys (order Cyclostomata) are living representatives of an ancient group of jawless vertebrates (class Agnatha). Studies on cyclostome hearts may provide insights into the evolution of the vertebrate heart and thereby increase our ...

Effect of fish meal replacement by Chlorella meal with dietary cellulase addition on growth performance, digestive enzymatic activities, histology and myogenic genes' expression for crucian carp Carassius auratus [PDF]

open access: yes, 2017
This study was conducted to investigate the effects of fish meal (FM) replacement by Chlorella meal (CM) with dietary cellulase supplementation on growth performance, digestive enzymatic activities, histology and myogenic genes' expression in crucian

Comparison of the Carp and the Crucian Carp from Pisci-cultural Point of View

open access: yesNIPPON SUISAN GAKKAISHI, 1955
With regard to ecological characteristics of the carp and the crucian carp when used as objects of loosely diffused culture, the present study was carried out to compare them with each other. (1) Survival rate of the crucian carp is always higher than that of the carp, and yearlings of the crucian carp grow faster than the other in such circumstances ...

The Olfactory Nervous System Of Terrestrial And Aquatic Vertebrates [PDF]

open access: yes, 2011
Animals in their natural milieu are surrounded by odors. These odors are rich source of information, and are perceived by sophisticated olfactory systems, that have evolved over time.

Consequences of fish for cladoceran, water beetle and macrophyte communities in a farmland pond landscape: implications for conservation [PDF]

open access: yes, 2017
Traditionally, fish have been neglected in pond ecology and conservation studies and it has frequently been assumed that they have a detrimental impact on pond biodiversity and ecosystem function.
